In the theory of dynamical systems, a state variable in a system is said to be unstable if it evolves without bounds. A system itself is said to be unstable if at least one of its state variables is unstable. In continuous time control theory, a system is unstable if any of the roots of its characteristic equation has real part greater than zero (or if zero is a repeated root). This is equivalent to any of the eigenvalues of the state matrix having either real part greater than zero, or, for the eigenvalues on the imaginary axis, the algebraic multiplicity being larger than the geometric multiplicity.

For Gliese 581c, the upper bound is 10.4 Earth masses.
In the preface to the score, she states that split tones "tend to be unstable and prone to distortion," and, "it is expected that a degree of fluctuation or 'fraying' will occur in most split tones and this should be regarded as part of the overall timbral quality of the trumpet part."Lim, Liza. Ehwaz. Ricordi, 2010. p. I.
The early skaffie boats located on the Stotfield beach were small with rounded stems and raked sterns. They were two-masted with a tall dipping lug sail and a mizzen sail.

Some geologists consider an unstable rock face at Mount Breakenridge, above the north end of the giant fresh-water fjord of Harrison Lake in the Fraser Valley of southwestern British Columbia, Canada, to be unstable enough to collapse into the lake, generating a megatsunami that might destroy the town of Harrison Hot Springs (located at its south end).
To summarize, usually the Crank-Nicolson scheme is the most accurate scheme for small time steps. For larger time steps, the implicit scheme works better since it is less computationally demanding. The explicit scheme is the least accurate and can be unstable, but is also the easiest to implement and the least numerically intensive. Here is an example.
Another parameter which is less commonly a factor is the trailer moment of inertia. Even if the center of mass is forward of the wheels, a trailer with a long load, and thus large moment of inertia, may be unstable. Some vehicles are equipped with a Trailer Stability Program that may be able to compensate for improper loading.
By sacrificing gain, it also has an additional effect of increasing the bandwidth of the amplifier. However, a negative feedback amplifier can be unstable such that it may oscillate. Once the stability problem is solved, the negative feedback amplifier is extremely useful in the field of electronics. Black published a famous paper, Stabilized feedback amplifiers, in 1934.
A leapfrog filter can be difficult to tune because of the complicated feedback. One strategy is to open the feedback loops so that the remaining filter structure is a simple cascade design. Each section can then be tuned independently. The inner sections, H2 and H3 have infinite Q and may be unstable when the feedback loops are opened.
A systematic review found that hyaluronate might be beneficial for clinical TMD signs in the long term, but that this may be unstable. The effects of hyaluronate may be similar to glucocorticoids.

In a dynamical system, multistability is the property of having multiple stable equilibrium points in the vector space spanned by the states in the system. By mathematical necessity, there must also be unstable equilibrium points between the stable points. Points that are stable in some dimensions and unstable in others are termed unstable, as is the case with the first three Lagrangian points.
Orthoformic acid or methanetriol is a hypothetical compound with the formula HC(OH)3. In this molecule, the central carbon atom is bound to one hydrogen and three hydroxyl groups. Orthoformic acid has not been isolated to date, and is believed to be unstable, decomposing into water and formic acid.Böhm, S., Antipova, D. and Kuthan, J. (1996), "Study of methanetriol decomposition mechanisms".
For a hybrid to be viable, the chromosomes of the two organisms will have to be very similar, i.e., the parent species must be closely related, or else the difference in chromosome arrangement will make mitosis problematic. With polyploid hybridization, this constraint is less acute. Super-numerary chromosome numbers can be unstable, which can lead to instability in the genetics of the hybrid.
X-ray structures have shown N-C-X bond angles of ca. 104 ° and 109 ° respectively. Carbenes that formally derive from imidazole-2-ylidenes by substitution of sulfur, oxygen, or other chalcogens for both α-nitrogens are expected to be unstable, as they have the potential to dissociate into an alkyne (R1C≡CR2) and a carbon dichalcogenide (X1=C=X2).
Six months after "Ricksy Business", Rick decides to unfreeze time. He warns Morty and Summer that their chronological time could initially be unstable. Rick encourages Beth and Jerry to go out for ice cream to allow them time to stabilize. Morty and Summer argue, and the resulting uncertainty tears time apart into two realities—depicted visually as two mostly synchronized parallel realities.
The latter complex was characterized by NMR spectroscopy, which demonstrated the utility of this technique in the study of metal hydride complexes. In 1957, Chatt, Shaw, and Duncanson described trans-PtHCl(PEt3)2 the first non-organometallic hydride (i.e., lacking a metal-carbon bond). It was shown to be air-stable, correcting long-held prejudice that metal hydrides would be unstable.
Under certain conditions, the shock wave in front or within a duct may be unstable, and oscillate upstream and downstream. This phenomenon is known as buzz. Stronger shock waves interacting with low momentum fluid or boundary layer tend to be unsteady and cause buzz. Buzz conditions can cause structural dynamics-induced failure if adequate margins are not incorporated into design.
Northland Region Corrections Facility is located 5 km northeast of the town of Kaikohe and is colloquially known as Ngawha - after the local area. Maori in Northland tried to persuade the Corrections Department not to upset a local taniwha by building the prison on thermal land. They were unsuccessful and the facility opened in 2005. Following completion, the foundations proved to be unstable.
The maintained cell lines after this differentiation event are largely dependent on PRC2. Without it, pluripotency genes will still be active, causing the cells to be unstable and reversion back to a stem cell-like stage where the cell would have to undergo differentiation again in order to return to its normal state. Properly differentiated cells have silenced pluripotency genes.
On the other side of the valley of stability, this ratio is large, corresponding to an excess of neutrons over protons in the nuclides. These nuclides tend to be unstable to β− decay, since such decay converts neutrons to protons. On this side of the valley of stability, β− decay also serves to move nuclides toward a more stable neutron- proton ratio.
145London 2003, p. 173. The first three aircraft were used as prototypes, with the first being launched on 31 October 1938, after numerous delays during design and construction. The Lerwick was immediately found to be unstable in the air, on the water and not suited to "hands off" flying. The latter was a major problem in an aircraft designed for long-range patrols.
The protein's chemical formula is C44189H71252N12428O14007S321. It has a theoretical Instability Index (II) of 51.63, indicating that it would be unstable in a test tube. The protein's in vivo half-life, the time it takes for half of the amount of protein in a cell to disappear after its synthesis in the cell, is predicted to be approximately 30 hours (in mammalian reticulocytes).
2-methyl-3-buten-2-ol is structurally similar to tert-amyl alcohol which was historically used as an anesthetic. Hops tend to be unstable when exposed to light or air and lose their potency after a few months' storage. Hops are of interest for hormone replacement therapy and are under basic research for potential relief of menstruation-related problems.
This also filled out the system inside e's orbit; additional planets there would be unstable at this system's age. In 2014, reanalysis of the existing radial velocities showed the possible presence of two additional planets. These planets would have almost the same mass as Gliese 876d. In 2018 a study using hundreds of new radial velocity measurements found no evidence for these planets.
If the reduction is maintained, then the cast should continue for 4 to 6 weeks. If the fracture is displaced, surgical management is the proper treatment. If the instability risk of the wrist is more than 70%, then surgical management is required. 43% of displaced fractures will be unstable within the first two weeks and 47% of the remaining unstable fractures will become unstable after two weeks.
The Servian Wall goes along the bank of the river, is pierced by the Porta Trigemina (you can see the three openings) and starts up the Aventine. Beyond the gate is the Forum Boarium. In the immediate foreground are the docks, or Navalia. The pier is highly unlikely, as any ship tied up at it as shown would be unstable in the full force of the current.
The Blackburd was found to be unstable, with the first prototype crashing before trials were complete. The second and third aircraft were fitted with an enlarged rudder. The Blackburd was considered to be inferior to the Shirl, and was therefore not ordered. Although orders were placed for production of the Shirl, they were almost immediately cancelled in favour of more orders for the Sopwith Cuckoo.
The replicative form of SpV1 has been attempted to be used as a vector to express foreign genes in S. citri R8A2. The goal is to allow foreign genes to be transcribed, translated into proteins, and maintained in a stable form for generations. However, the recombinant viral DNA can prove to be unstable after passaging. SpV1-R8A2 B can be isolated from its host.
Decays are mediated by one or several fundamental forces. The particles in the final state may themselves be unstable and subject to further decay. The term is typically distinct from radioactive decay, in which an unstable atomic nucleus is transformed into a lighter nucleus accompanied by the emission of particles or radiation, although the two are conceptually similar and are often described using the same terminology.
Numerous banks that were started during this period ultimately proved to be unstable. In many Western states, the banking industry degenerated into "wildcat" banking because of the laxity and abuse of state laws. Bank notes were issued against little or no security, and credit was over extended; depressions brought waves of bank failures. In particular, the multiplicity of state bank notes caused great confusion and loss.
Trinitromethane forms a series of bright yellow ionic salts. Many of these salts tend to be unstable and can be easily detonated by heat or impact. The potassium salt of nitroform, KC(NO2)3 is a lemon yellow crystalline solid that decomposes slowly at room temperatures and explodes above 95 °C. The ammonium salt is somewhat more stable, and deflagrates or explodes above 200 °C.
At the east end he added a bay and an apse, creating a chancel. The north and south galleries were removed, and a baptistery was created at the base of the tower. In the 1950s the tower was found to be unstable, and its upper parts, consisting of superimposed cupolas, were removed. In 1961, and again in 1971, the church had to be restored following serious fires.
Many of these coinages have proven to be unstable, and have either fallen out of use or been replaced with pronunciations more in keeping with the developing norms, such as pobo for poŭpo, vato for ŭato, and maĉo for matĉo. On the other hand, the word jida ('Yiddish'), which was also sometimes criticized on phonotactical grounds but had been used by Zamenhof, is well established.
The Lena Water Tower is a water tower located in the village of Lena, Illinois, United States. It was built in 1896 following two decades of problems with structure fires in the village. The current water tower is the result of a second attempt after the first structure proved to be unstable. The tower stands tall and is built of limestone and red brick.
As they settle down in a compartment for the rest of their journey, the assassin shows up and demands the notebook. He takes Kelso to see Mamantov. Mamantov explains how he planned for Kelso to come to Moscow to speak at the conference, discover the notebook and reveal Josef to Russia. Kelso believes Josef to be unstable and that Mamantov might be his first victim.
In practice, the linear equations that we work with are linearisations of more complicated governing equations such as the Navier–Stokes equations about some base state, with the linearisations carried out under the assumption that the perturbation quantity y is small. Transient growth may violate this assumption. When nonlinear effects are considered, then a system may be unstable even if the linearised system is stable.
The government, however, turned out to be unstable and finally collapsed during October 2011, leading to snap elections. After months of steady polling between 6 and 9 percents, the party received 6.89% of the popular vote in the 2012 elections, winning 13 seats. As in 2010, SMK-MKP failed to reach the required threshold, leaving Most–Híd as the only parliamentary party representing the interest of the Hungarian minority in Slovakia.
1,2-Dithiins are isomers of but-2-ene-dithials. They tend to be unstable with respect to loss of sulfur and formation of the thiophene derivative:Block, Eric et al, "Synthesis, Properties, Oxidation, and Electrochemistry of 1, 2-Dichalcogenins" Journal of the American Chemical Society (2000), 122(21), 5052-5064. :C4R4S2 → C4R4S + "S" They are often claret-colored. Some occur as flower pigments in plants of the family Asteraceae.
Monsieur Ouine has its origin in a spiritual crisis Bernanos went through in the early 1930s, when he contemplated how nihilism and despair lead to evil. The book took nine years to write and the author considered it to be his most ambitious work. The plot is purposely ambiguous and in certain parts inconsistent, as Bernanos considered evil to be unstable and wanted the novel to reflect this.
Knowing the audience is essential to accuracy because the language will be tailored according to what they already understand about the subject at hand. For example, instructions on how to correctly and safely assemble a bookshelf are included with purchase. Those instructions are constructed so that anyone can follow along, including accurate details as to where each fastener goes. If those instructions were inaccurate, the bookshelf could be unstable and fail.
In 1988, the Bureau of Reclamation completed a study that concluded that the dam needed modifications to prevent a failure should a significant flood or an earthquake occur. Earlier floods that had resulted in water topping the dam had eroded the abutments, and the buttresses were judged to be unstable. Work started in 1991 and included an access road to the downstream side of the dam. The work concluded in 1995.
Sneha was rumoured to play Arjun's sister-in-law. Upendra was confirmed in a role paralleling Arjun's in the film, and Sharma reportedly wore a traditional attire to suit her role. Sharma's character was revealed to be unstable, while Arjun's character was nuanced; he was confirmed as an event manager in late October 2014. Nithya Menen would reportedly play a negative role as Upendra's sister in the film.
Tropical cyclones have intensified when SSTs were slightly below this standard temperature. Tropical cyclones are known to form even when normal conditions are not met. For example, cooler air temperatures at a higher altitude (e.g., at the 500 hPa level, or 5.9 km) can lead to tropical cyclogenesis at lower water temperatures, as a certain lapse rate is required to force the atmosphere to be unstable enough for convection.
If, on the contrary, the errors grow with time the numerical scheme is said to be unstable. The stability of numerical schemes can be investigated by performing von Neumann stability analysis. For time-dependent problems, stability guarantees that the numerical method produces a bounded solution whenever the solution of the exact differential equation is bounded. Stability, in general, can be difficult to investigate, especially when the equation under consideration is nonlinear.
Richard proved to be ineffectual and was unable to maintain his rule. He resigned his title and retired into obscurity. The Rump Parliament was recalled and there was a second period where the executive power lay with the Council of state. But this restoration of Commonwealth rule, similar to that before the Protectorate, proved to be unstable, and the exiled claimant, Charles II, was restored to the throne in 1660.
In an alternate New 52 timeline, the New 52 Superman married Lois Lane and had a son, whom they named Jon Lane Kent. Jon's hybrid Kryptonian/human physiology proved to be unstable, causing him to fall ill and die shortly before his fourth birthday. In grief, Superman and Lois retreated to the Fortress of Solitude and were never heard from again. However, this death was not the end for Jon.
An alliance was then formed between Zain al-Abidin, Shah Yahya and 'Imad ad-Din Ahmad against Shah Mansur. The alliance proved to be unstable, however, and when they met Shah Mansur's army at Furg, Shah Yahya failed to show and 'Imad ad- Din Ahmad quickly retreated. The latter met Shah Mansur again, this time at Fasa, but lost and was captured in Ray. He was blinded and imprisoned.
Although these sites had been used since Roman times, William Smith developed new methods for the identification of deposits of fuller's earth to the south of Bath. Other English sources include a mine near Redhill, Surrey (worked until 2000), and Woburn, Bedfordshire, where production ceased in 2004. Hills, cliffs, and slopes that contain fuller's earth can be unstable, since this material can be thixotropic when saturated by heavy rainfall.
In such situations, it might be actually difficult to identify this region correctly. When the force is attractive, the cantilever is attracted to the surface and may become unstable. From stability considerations one finds that the cantilever will be unstable provided : dF/dh > k This instability is illustrated in the right panel of the figure on the right. As the cantilever approaches, the slope of the force curve increases.
Max Tegmark expands on the preceding argument in the following anthropic manner. If T differs from 1, the behavior of physical systems could not be predicted reliably from knowledge of the relevant partial differential equations. In such a universe, intelligent life capable of manipulating technology could not emerge. Moreover, if T > 1, Tegmark maintains that protons and electrons would be unstable and could decay into particles having greater mass than themselves.
Microsoft Visual SourceSafe (VSS) is a discontinued source control program, oriented towards small software development projects. Like most source control systems, SourceSafe creates a virtual library of computer files. While most commonly used for source code, SourceSafe can handle any type of file in its database, but older versions were shown to be unstable when used to store large amounts of non-textual data, such as images and compiled executables.
This contradiction shows that assigning all doctors to their best matches gives a matching. It is a stable matching, because any unstable pair would also be unstable for one of the matchings used to define best matches. As well as assigning all doctor to their best matches, it assigns all hospitals to their worst matches. In the partial ordering on the matchings, it is greater than all other stable matchings.
Strong tones can occur in both rectangular and circular jets when the pressure ratio is greater than the critical and the flow becomes supersonic on exit, resulting in a sequence of repetitive shock cells. These cells can be seen in the exhaust of rockets or jets operating with an afterburner. As with subsonic jets, these flows can be unstable. In a rectangular jet, the instability can show as asymmetric cell distortions.
The strength of the relationship is evaluated on the basis of time the individuals spend together, as well as on the emotional intensity of their relationship. A dyad can be unstable because both persons must cooperate to make it work. If one of the two fails to complete their duties, the group would fall apart. Because of the significance of marriages in society, their stability is very important.
With the completion of the viaduct, Folkestone station opened on 18 December 1843. East of Folkestone, a hard gault ridge was bored through by the Martello Tunnel, which took its name from a nearby Martello Tower. Between Folkestone and Dover, there were three headlands, Abbott's Cliff, Round Down Cliff and Shakespeare's Cliff. The first and last were of sound chalk, but Round Down Cliff's chalk was of a different character, being found to be unstable.
One significant danger is from flying debris, which, when improperly prepared for, can kill onlookers. Another dangerous scenario is the partial failure of an attempted implosion. When a building fails to collapse completely the structure may be unstable, tilting at a dangerous angle, and filled with un-detonated but still primed explosives, making it difficult for workers to approach safely. A third danger comes from air overpressure that occurs during the implosion.
Children's tricycle Children's plastic tricycle Compared to adult trikes, children's model are simpler, without brakes or gears, and often with crude front-drive. Tricycles are typically used by children between the ages of two and five, after which point they usually switch to a bicycle, often with training wheels (stabilisers). Child trikes can be unstable, particularly if the wheelbase or track are insufficient. Some trikes have a push bar so adults can control the trike.
John visits Matt again the following week where he appears to be unstable following his actions. Matt suggests that John puts his guilt into perspective, before giving him a stronger prescription. Matt visits Peter Barlow (Chris Gascoyne) at his home after Peter takes a fall while recovering from the injuries sustained from the events of the tram crash. Matt has an awkward incident with Sunita's aunts who are trying to find her a new husband.
A few types of vehicle use only rear wheel steering, notably fork lift trucks, camera dollies, early pay loaders, Buckminster Fuller's Dymaxion car, and the ThrustSSC. In cars, rear wheel steering tends to be unstable because in turns the steering geometry changes hence decreasing the turn radius (over steer), rather than increase it (under steer). Rear wheel steering is meant for slower vehicles that need high- maneuverability in tight spaces, e.g. fork lifts.
Covalent association of two domains represents a functional and structural advantage since there is an increase in stability when compared with the same structures non-covalently associated. Other, advantages are the protection of intermediates within inter-domain enzymatic clefts that may otherwise be unstable in aqueous environments, and a fixed stoichiometric ratio of the enzymatic activity necessary for a sequential set of reactions. Structural alignment is an important tool for determining domains.
The city has established a council to govern all aspects of the city life. The council members consist of Skandranon, Amberdrake, Cinnabar, Judeth, and Snowstar. The Cataclysm has led to mage storms that causes magic to be unstable, meaning that many that had the mage ability have lost their powers, or are seriously weakened. Amberdrake as one of the council members brings up a man that is practicing as a kestra'chern illegally.
Empirically derived NDVI products have been shown to be unstable, varying with soil colour, soil moisture, and saturation effects from high density vegetation. In an attempt to improve NDVI, Huete Huete, A.R., (1988) 'A soil- adjusted vegetation index (SAVI)' Remote Sensing of Environment, vol. 25, issue 3, pp. 259-309. DOI: 10.1016/0034-4257(88)90106-X developed a vegetation index that accounted for the differential red and near-infrared extinction through the vegetation canopy.
San Francisco's shoreline has grown beyond its natural limits. Entire neighborhoods such as the Marina, Mission Bay, and Hunters Point, as well as large sections of the Embarcadero, sit on areas of landfill. Treasure Island was constructed from material dredged from the bay as well as material resulting from the excavation of the Yerba Buena Tunnel through Yerba Buena Island during the construction of the Bay Bridge. Such land tends to be unstable during earthquakes.
The System 100 is still sought-after due to its filter, sequencer and patching capabilities, though the oscillators can be unstable at the lower frequencies, and the keyboard is prone to mis-triggering and double-triggering if not used regularly. Generally, however, it is a robust and reliable system. The SH-5 and SH-7 are similar in styling, but both have fixed signal paths, as opposed to the semi-modular System 100.
Phyllis and Michael began a wild affair. With the help of Brian, all of Phyllis's lies and manipulations were brought out in court, including the fact that Danny had been drugged that first time and never even made love with Phyllis as she had claimed. The court found her to be unstable and an unfit mother. Danny won custody of Daniel, whom he still considered his son, although Phyllis was allowed visitation.
Safety hazards of fire cleanup include the risk of re-ignition of smoldering debris, electrocution from downed or exposed electrical lines or in instances where water has come into contact with electrical equipment. Structures that have been burned may be unstable and at risk of sudden collapse. Other safety hazards may include flammable gases (i.e., propane) and gas storage tanks, tree work, confined spaces, sharp or flying objects, and heat related illnesses.
The recent theoretical results have therefore undergone much scrutiny and most of them are now ruled out by theoretical studies. For example, several alternative black hole models were shown to be unstable in extremely fast rotation, which, by conservation of angular momentum, would be a not unusual physical scenario for a collapsed star (see pulsar). Nevertheless, the existence of a stable model of a nonsingular black hole is still an open question.
Overlooking Y Ravine is the memorial to 51st (Highland) Division. The ground originally donated by the commune of Beaumont-Hamel to the Veterans of the 51st Division was found to be unstable because of the many dugouts beneath it. Lieutenant Colonel Nangle offered a location overlooking Y Ravine within the Beaumont-Hamel Newfoundland Memorial site. The Y ravine had been the scene of fierce fighting for the division on 13 November 1916.
The fourth chain has no such long lasting bottleneck isotope, so almost all of the isotopes in that chain have long since decayed down to very near the stability at the bottom. Near the end of that chain is bismuth-209, which was long thought to be stable. Recently, however, bismuth-209 was found to be unstable with a half-life of 19 billion billion years; it is the last step before stable thallium-205.
The inaugural service of the tram occurred on Saturday, 3 May 1862. A trial run between the city and the port showed amongst other things that fears the tram would be unstable when fully laden on account of the narrow gauge were not warranted. Vibrations were experienced, however, due to the wheels being locked to the axles. Fare paying passengers were carried throughout the day, with regular services commencing at 0900 the following Monday.
Low Force Waterfalls Low Force is an 18-foot (5.5m) high set of falls on the River Tees, England, UK. Further upstream is the High Force waterfall. Low Force is also the site of the Wynch Bridge, completed in 1830. It is suggested that only one person at a time should cross the bridge as it may be unstable. Low Force is within the North Pennines Area of Outstanding Natural Beauty (AONB) and European Geopark.
The Xbox 360 version of Bully: Scholarship Edition was found to be unstable on some players' consoles, resulting in glitches, crashes and performance issues. On 20 March, a patch was released, but there were reports claiming that the problems continued or worsened. When the Windows 10 version was released in July 2015, many users reported constant crashes and errors; many of these problems were addressed by an unofficial patch released by a fan.
This section of the river flows through a farm with free-roaming cattle. These cattle trampled the riverbanks, causing them to be unstable. This instability led to excessive erosion, which degraded fish habitat downstream of the site, and also led to excessive widening of the river where it passed through the farm. In 2006, a river restoration project was completed, in which this section of river was restored to a normal width.
SAPS analysis predicted that this protein would be unstable. Due to its high hydrophilicity, this protein definitely does not contain transmembrane segments. Protein sequence for the major form of CCDC130. This peptide is 396 amino acids long, contains a coiled-coil region from 182-214, a domain of unknown function (DUF572), and the COG5134 domain in the N-terminal half Alternative splicing variants of the CCDC130 protein as seen on AceView from NCBI.
The Kadomtsev model uses a resistive magnetohydrodynamic (MHD) description of the plasma. If the amplitude of the current density in the plasma core is high enough so that the central safety factor q_{0} is below unity, a m=1 linear eigenmode will be unstable, where m is the poloidal mode number. This instability may be the internal kink mode, resistive internal kink mode or m=1 tearing mode.Coppi, B. et al. (1976).
Cornell, Wieman and Ketterle won the 2001 Nobel Prize in Physics for their achievements. A group led by Randall Hulet at Rice University announced a condensate of lithium atoms only one month following the JILA work. Lithium has attractive interactions, causing the condensate to be unstable and collapse for all but a few atoms. Hulet's team subsequently showed the condensate could be stabilized by confinement quantum pressure for up to about 1000 atoms.
In the late 1970s, Egypt had several cohabitation governments which proved to be unstable, due to the struggle arising between the president and the prime minister. From 1981 until 2011, the National Democratic Party had maintained a majority in the People’s Assembly and supplied the Egyptian president. The National Democratic Party was dissolved by the supreme administrative court on 16 April 2011, following the Egyptian uprising which eventually caused the resignation of Hosni Mubarak.
In 1913 Johannes Stark proposed that three hydrogen nuclei and electrons could form a stable ring shape. In 1919 Niels Bohr proposed a structure with three nuclei in a straight line, with three electrons orbiting in a circle around the central nucleus. He believed that H3+ would be unstable, but that reacting H2− with H+ could yield neutral H3. Stanley Allen's structure was in the shape of a hexagon with alternating electrons and nuclei.
PG-X, which later would become known as prostacyclin, was 30 times more potent than any other known anti-aggregatory agent. By 1976, Vane and fellow researcher Salvador Moncada published the first paper on prostacyclin, in the scientific journal Nature. The collaboration produced a synthetic molecule which was given the name epoprostenol. But like native prostacyclin, the structure of the epoprostenol molecule proved to be unstable in solution, prone to rapid degradation.
In 1948 there was a chronic shortage of large passenger tank locomotives on the un-electrified lines of the former London Brighton and South Coast Railway. As a result, trials of the class were made with passenger stock between Victoria railway station and Tunbridge Wells West railway station via the Oxted Line. However, like the K and K1 classes the W class were found to be unstable at speed and were banned from use on passenger trains.
There are three forms reported, anhydrous, a tetrahydrate and basic beryllium carbonate. The anhydrous form is reported to be unstable, decomposing to BeO and carbon dioxide, and requiring storage under CO2.Egon Wiberg, Arnold Frederick Holleman (2001) Inorganic Chemistry, Elsevier The tetrahydrate is said to be formed when CO2 is bubbled through a solution of Be(OH)2 and is also reported to be similarly unstable.David Anthony Everest, 1964, The Chemistry of Beryllium, Elsevier Pub. Co.
He also suggested that the absence of longitudinal waves suggested that the aether had negative compressibility. George Green pointed out that such a fluid would be unstable. George Gabriel Stokes became a champion of the entrainment interpretation, developing a model in which the aether might be (by analogy with pine pitch) rigid at very high frequencies and fluid at lower speeds. Thus the Earth could move through it fairly freely, but it would be rigid enough to support light.
Capable of achieving a millennium in terms of evolution in a matter of hours, it has an immense potential to manipulate life to levels never achieved before. Unfortunately, E-DNA proves to be unstable. All of the test subjects who came in contact with it were transformed into uncontrollable genetic mutants soon named The Darkspore. Fearing these new creatures, the Crogenitors throw hero Xylan into exile for his behavior and negligence, outlawing the use of E-DNA.
For anisotropic solids, the elastic term depends on direction in a manner which can be predicted by elastic constants and how the lattice parameters vary with composition. For the cubic case, Y is a minimum for either (100) or (111) directions, depending only on the sign of the elastic anisotropy. Thus, by describing any composition fluctuation in terms of its Fourier components, Cahn showed that a solution would be unstable with respect to sinusoidal fluctuations of a critical wavelength.
Leishman, Dr. J. Gordon, Technical Fellow of AHS International. "Paper." 64th Annual Forum of the American Helicopter Society International, on the aerodynamic capability of Cornu's design, arguing that the aircraft lacked the power and rotor loading to lift free of the ground in manned flight. Cornu's helicopter completed a few more flights and achieved a height of nearly , but it proved to be unstable and was abandoned. In 1911, Slovenian philosopher and economist Ivan Slokar patented a helicopter configuration.
There were around 60,000 people at the beatification and it was rumored that her killer was present, as was President Mobutu Sese Seko. Her killer tried to secure a meeting with the pope to express his great remorse but it was denied. Joaquín Navarro said the audience was refused because the former colonel made the request through a news editor who interviewed him. One source said a contributing factor was that he was considered to be unstable.
The geocentric orbit of is chaotic due to the combined effects of tidal forces from the Sun and Earth as well as repeated close encounters with the Moon. The Moon gravitationally perturbs 's geocentric orbit, causing it to be unstable. Over the course of 's orbit around Earth, repeated close encounters with the Moon will eventually lead to ejection from its geocentric orbit as the Moon's perturbations can transfer enough momentum for to escape Earth's gravitational influence.
Garnet growth zoning is a special type of geothermobarometry that focuses on the composition variations in garnet. Zoning is a texture in solid-solution minerals which the minerals form concentric rings from core to rim upon changing P-T conditions. In a changing environment, minerals would be unstable and alter itself to reduce its Gibbs free energy to achieve stable states. However, sometimes the mineral core has not reached equilibrium upon the environmental change and zoning occurs.
However, not all the risk of the project is transferred to the private sector; only the ones they can muster, as outlined in the contract. Auditor Generals of Quebec, Ontario and New Brunswick have publicly questioned P3 rationales based on a transfer of risk, the latter stating he was "unable to develop any substantive evidence supporting risk transfer decisions". Furthermore, many PPP concessions proved to be unstable and required to be renegotiated that favour the contractor.
The walls of such lakes can be unstable and may be breached after fresh earthquakes or because of erosion. As water rushes outwards, the initial channel is cut wider and deeper, further increasing the flow. This may cause the lake's rim to collapse abruptly. The usual result is for huge amounts of water to be displaced, incorporating a great deal of sediment which increases it in volume by as much as two or four times, or even more.
The original bridge is medieval and the second one, a stone structure, built in 1753 and upgraded in 1777 and in 1814, was erected when the original bridge was thought to be unstable. The builders of the 1753 structure used the original bridge (circa 1075–1200) to support scaffolding during construction and added a second arch. The 1901 structure eliminated the slope in the roadway. In 1971, the steelwork and railings were repaired and the bridge was strengthened.
The Devonian shale bedrock of the area is overlain by of compact glacial till, followed by of stiff clay, of weak clay, of silt, of sand, and of fill dirt. These layers cause the hillside to be unstable. About above the mean water line, the shear strength is , while at the top of the hill the shear strength is . Geological data indicate that the hill is sliding into the river at a rate of about per year.
In cystic fibrosis, a point mutation in the Cystic Fibrosis Transmembrane Conductance Regulator protein, ΔF508-CFTR, causes it to be unstable and misfold, hence trapped in the endoplasmic reticulum and unable to reach the cell membrane. This lack of CFTR in the cell membrane leads to disrupted chloride transport and the symptoms of cystic fibrosis. Sodium phenylbutyrate can act as a chemical chaperone, stabilising the mutant CFTR in the endoplasmic reticulum and allowing it to reach the cell surface.
The line of beta stability follows a particular curve of neutron–proton ratio, corresponding to the most stable nuclides. On one side of the valley of stability, this ratio is small, corresponding to an excess of protons over neutrons in the nuclides. These nuclides tend to be unstable to β+ decay or electron capture, since such decay converts a proton to a neutron. The decay serves to move the nuclides toward a more stable neutron-proton ratio.
The original tripod was found to be unstable, which led to the development of a revised variant with a triangular base with a two- wheel carriage. This new variant was chosen for mass production, but at the time of the German attack in May 1940, only a few hundred of these guns were in service. With them and only approximately two hundred Oerlikons, the lack of modern light AA guns greatly hampered the French army in the campaign.
Stile Pot, Gaping Gill A boulder choke is a collection of large rocks or rubble that obstructs a shaft or passage in a cave or mine. In order to progress through passages cavers often need to negotiate or clear boulder chokes. Boulder chokes can be formed by rockfall, stream deposition, or mining debris. Due to the nature of their formation boulder chokes may be unstable and can prove difficult to navigate and map due to their complexity.
The Federal Highway Administration National Bridge Inventory found the sufficiency rating of the bridge structure to be only 14.6 percent. It found that the bridge's foundations were determined to "scour critical," meaning that the bridge's foundations were "determined to be unstable for the calculated scour conditions," and that the railing "does not meet currently acceptable standards". Its overall condition was deemed "basically intolerable requiring high priority of corrective action", with an estimated cost to improve the bridge of $107,000.
It responded to the trend -- clubs secretly paying or indirectly compensating players -- by establishing a "professional" class for 1869. As quickly as 1871, most of those clubs broke away and formed the National Association of Professional Base Ball Players (NAPBBP). That new, professional Association was open at a modest fee, but it proved to be unstable. It was replaced by the National League of Professional Base Ball Clubs in 1876, which has endured to the present day.
The outburst may have been the result of a so-called mergeburst, the merger of two main sequence stars (or an main sequence star and a pre-main sequence star). This model is strengthened by the apparent youth of the system and the fact that multiple stellar systems may be unstable. The less massive component may have been in a very eccentric orbit or deflected towards the massive one. Computer simulations have shown the merger model to be plausible.
This town sits directly north of Patapo, and is considered to be part of the greater town. A dried up river separates the two towns geographically. There are unnamed bridges that can support vehicles, part of La Florida, Av. Trapiche, and the highway 6A from west to east. Additionally, a footbridge spans it in between the former two; the bridge is known locally to be unstable, it wobbles frequently and the structure collapsed at one point.
As for the idea that the private sector is inherently better at managing risk, there has been no comprehensive study comparing risk management by the public sector and by P3s. Auditor Generals of Quebec, Ontario and New Brunswick have publicly questioned P3 rationales based on a transfer of risk, the latter stating he was "unable to develop any substantive evidence supporting risk transfer decisions". Furthermore, many PPP concessions proved to be unstable and required to be renegotiated that favor the contractor.
Marie and Pierre coined the term "radioactivity" to describe this property of matter, and isolated the radioactive elements radium and polonium. Ernest Rutherford and Frederick Soddy identified two of Becquerel's forms of radiation with electrons and the element helium. Rutherford identified and named two types of radioactivity and in 1911 interpreted experimental evidence as showing that the atom consists of a dense, positively charged nucleus surrounded by negatively charged electrons. Classical theory, however, predicted that this structure should be unstable.
The original magic roundabout had six exits in total, with the British Petroleum building spanning "Marlowes", the road leading to the town centre, in the approximate position of the earlier railway viaduct. The BP building was found to be unstable due to defective reinforced concrete and the exit had to be closed. The building was demolished but the original route was not restored, although a newer side exit from the roundabout replaced the junction with Marlowes off a side road.
Cold stabilization causes tartrates to crystallize and precipitate out of the wine. As a complex chemical mixture dependent on the activity of microorganisms, wine can be unstable and reactive to changes in its environment. Once bottled, a wine may be exposed to extremes of temperature and humidity, as well as violent movement during transportation and storage. These may cause cloudiness, sedimentation and/or the formation of tartrate crystals; more seriously, they may also cause spoilage or the production of carbonic gas.
Depending on the aircraft design and flight regime, its tailplane may create positive lift or negative lift (downforce). It is sometimes assumed that on a stable aircraft this will always be a net down force, but this is untrue..p.19p.20p.21 On some pioneer designs, such as the Bleriot XI, the centre of gravity was between the neutral point and the tailplane, which also provided positive lift. However this arrangement can be unstable and these designs often had severe handling issues.
The inner part of the galaxy, where active star formation has been observed, has been found to be unstable, contrary to the outer stable one. It has been suggested that the presence of molecular clouds accounts for the instability of the region. The nucleus of NGC 2985 is active, and based on its spectrum has been categorised as a LINER. The most accepted theory for the activity source is the presence of an accretion disk around a supermassive black hole.
Limnological studies carried out by the Central Public Health Engineering Research Institute, Nagpur, India, in 1964, indicated an unstable thermal stratification in the lake waters. The dissolved oxygen (DO) values were found to increase in some months and carbon dioxide was found to be less at the surface than at the bottom. In cooler season, the surface water was found to be less alkaline, which could be attributed to the photosynthesis activity of the algae. The pH stratification was found to be unstable.
At Odenwald she met and became lifelong friends with Klaus Mann who would later become a well-known writer. Geheeb considered Schottmüller to be unstable during the whole period she attended Odenwald School but she still managed to pass her Abitur in 1924. Between 1924 and 1927 Schottmüller completed an arts and crafts education in goldsmithing, pottery and enamel in Pforzheim and Frankfurt. Her family would not support her in becoming a sculptor and dancer, something she had practised at the Odenwald School.
Such an orbit would be unstable unless it was a Jupiter trojan. Jupiter trojans have (4.6 AU < semi- major axis < 5.5 AU; eccentricity < 0.3). The nominal semi-major axis of ' is just outside of the asteroid belt. As more observations come in, it is expected the orbit determination will be that of a main belt asteroid as they are by far the most numerous discovered objects in the solar system and account for 94% of all known Small Solar System bodies.
Knowing the situation to be unstable, Roh tries to leave quietly with Vanye and Fwar's band, but the khal are alerted and pursue. It is a close race, but some of them reach the shelter of the forest, where the few barrowlanders not caught and killed by the khal are dispatched by Roh and Vanye. Vanye guides Roh to Merir, but the lord of Shathan has no news of Morgaine. Merir decides that they must go to Nehmin for answers.
Various explanations were proposed during the 1960s and 1970s, each with their own problems. It was suggested that quasars were nearby objects, and that their redshift was not due to the expansion of space (special relativity) but rather to light escaping a deep gravitational well (general relativity). This would require a massive object, which would also explain the high luminosities. However, a star of sufficient mass to produce the measured redshift would be unstable and in excess of the Hayashi limit.
All Saints' Cathedral The cathedral church of the diocese is All Saints' Cathedral, Bathurst in the heart of the city. The cathedral building was originally designed by Edmund Blacket in 1845 as a parish church, but became a cathedral in 1870 with the creation of the Diocese of Bathurst. An organ was installed in 1886 and bells were hung in 1855. In the 1890s, however, the bell tower was found to be unstable, so the bells could not be "rung full circle" but only by striking them.
The LAV III's turret gives the vehicle a higher centre of gravity than the vehicle was initially designed for. This has led to concerns that the vehicle is more likely to roll over on uneven terrain. While there have been several recorded rollovers (about 16), the most common cause was found to be unstable terrain, specifically road shoulders unexpectedly giving away beneath the vehicle. The weight balance of the LAV III is taken into consideration during driver training, largely mitigating the chances of a rollover.
There are around 94 naturally occurring elements on earth. The atoms of each element have a nucleus containing a specific number of protons (always the same number for a given element), and some number of neutrons, which is often roughly a similar number. Two atoms of the same element having different numbers of neutrons are known as isotopes of the element. Different isotopes may have different properties - for example one might be stable and another might be unstable, and gradually undergo radioactive decay to become another element.
Tropical cyclones are known to form even when normal conditions are not met. For example, cooler air temperatures at a higher altitude (e.g., at the 500 hPa level, or 5.9 km) can lead to tropical cyclogenesis at lower water temperatures, as a certain lapse rate is required to force the atmosphere to be unstable enough for convection. In a moist atmosphere, this lapse rate is 6.5 °C/km, while in an atmosphere with less than 100% relative humidity, the required lapse rate is 9.8 °C/km.
The maximum length is limited by the distance between the peaks of the camelback humps; thus, a rod longer than that will be unstable and fall out of the trap. Both the radius and the length of the rod determine the damping of the system. The damping is primarily due to Stokes drag, as damping is non-observable under vacuum. Possible practical uses of the concept include being a platform for custom-designed 1D potentials, a highly sensitive force-distance transducer or a trap for semiconductor nanowires.
Although a controller may be stable when implemented as an analog controller, it could be unstable when implemented as a digital controller due to a large sampling interval. During sampling the aliasing modifies the cutoff parameters. Thus the sample rate characterizes the transient response and stability of the compensated system, and must update the values at the controller input often enough so as to not cause instability. When substituting the frequency into the z operator, regular stability criteria still apply to discrete control systems.
They have a double date where it seems that Deena and Henri are attracted to each other, although Henri dresses up in hippie clothing. The next day, Deena seems promoted from her career as a writer when someone could recognize her from an article she wrote. Kim on the other hand, seems to be an underdog as Francesca wouldn't allow to invest in her own dog service business. Laura, the other roommate seems to be unstable as she has been shifting jobs every week.

A system in equilibrium in which there is positive feedback to any change from its current state may be unstable, in which case the system is said to be in an unstable equilibrium. The magnitude of the forces that act to move such a system away from its equilibrium are an increasing function of the "distance" of the state from the equilibrium. Positive feedback does not necessarily imply instability of an equilibrium, for example stable on and off states may exist in positive- feedback architectures.
Trailer stability can be defined as the tendency of a trailer to dissipate side-to-side motion. The initial motion may be caused by aerodynamic forces, such as from a cross wind or a passing vehicle. One common criterion for stability is the center of mass location with respect to the wheels, which can usually be detected by tongue weight. If the center of mass of the trailer is behind its wheels, therefore having a negative tongue weight, the trailer will likely be unstable.
It proved to be unstable and affected by internal rivalries, and gradually broke apart. Different SSDF factions already fought each other in 1997 and 1998, and the government allowed it to happen as it mistrusted most of the SSDF anyway. The combat between the pro-government militias was fuelled by a desire of the warlords to control the oil-rich areas and thereby increase their revenue. Matip managed to oust Machar's followers and other rivals from the valuable region around Bentiu, drawing the latter's ire.
S. Route 29) which terminates and merges into K Street immediately east of the bridge. The central bridge is flanked by two flyover ramps that connect to the nearby terminus of Interstate 66.Ross, Amy (1992). History and Description (Drawing 10) The first bridge on the site was a stone arch bridge constructed in 1792; it was only the second crossing of Rock Creek built, the first being at M Street. This bridge was found to be unstable and its center arch was demolished in 1795.
The Arab League took over the protection of Kuwait and the British had withdrawn their forces by 19 October. Qasim was killed in a coup in 1963 but, although Iraq recognised Kuwaiti independence and the military threat was perceived to be reduced, Britain continued to monitor the situation and kept forces available to protect Kuwait until 1971. There had been no Iraqi military action against Kuwait at the time: this was attributed to the political and military situation within Iraq which continued to be unstable.
The Rolamite was invented by Sandia engineer Donald F. Wilkes and was patented on June 24, 1969. It was discovered while Wilkes was working on a miniature device to detect small changes in the inertia of a small mass. After testing an S-shaped metal foil, which he found to be unstable to support surfaces, the engineer inserted rollers into the S-shaped bends of the band, producing a mechanical assembly that has very low friction in one direction and high stiffness transversely. It became known as Rolamite.
A dust devil in Ramadi, Iraq. Atmospheric instability is a condition where the Earth's atmosphere is generally considered to be unstable and as a result the weather is subjected to a high degree of variability through distance and time.Stability of Air Atmospheric stability is a measure of the atmosphere's tendency to discourage or deter vertical motion, and vertical motion is directly correlated to different types of weather systems and their severity. In unstable conditions, a lifted thing, such as a parcel of air will be warmer than the surrounding air at altitude.
The new alloy was ultimately discovered to be problematic. It proved to be unstable and the noted imperfections in the diffraction pattern allowed for multiple explanations (including one about crystal twinning proposed by Linus Pauling) that were hotly debated for the next few years. In 1987, An-Pang Tsai and his group at Japan's Tohoku University made an important breakthrough with the synthesis of the first-ever stable icosahedral quasicrystal. It had sharp diffraction spots arranged in close accord with Steinhardt and Levine's quasicrystal theory and was inconsistent with any of the alternative explanations.
All plastic is subject to deterioration through physical or chemical means, and thus, motion picture film is at risk for the same reason. Films deteriorate over time, which can damage individual frames or even lead to the entire film being destroyed. Cellulose nitrate, cellulose diacetate and triacetate are known to be unstable media: improperly preserved film can deteriorate in a period of time much faster than many photographs or other visual presentations. Cellulose nitrate, because of its unstable chemistry, eventually breaks down, releasing nitric acid, further catalyzing the decomposition.
Ekman's solution has an intrinsic inflectional wind profile that was found to be unstable to long waves corresponding to the organized large vortices scale. The nonlinear theory showed that the growth of these finite perturbation waves modifies the mean flow, eliminating the dynamic inflectional instability energy so that equilibrium is obtained. The modified mean flow corresponds well with observations. This solution for the layer containing the PBL-scale roll wavelength requires a modification of the flux transports to accommodate modeling of the advective motion of the large vortices.
The Saturnian moon Rhea may have a tenuous ring system consisting of three narrow, relatively dense bands within a particulate disk, the first predicted around a moon. Most rings were thought to be unstable and to dissipate over the course of tens or hundreds of millions of years. Studies of Saturn's rings however indicate that they may date to the early days of the Solar System. Current theories suggest that some ring systems may form in repeating cycles, accreting into natural satellites that break up as soon as they reach the Roche limit.
Immediately west of Tanaga volcano lies Sajaka, a compound edifice. Takawangha's summit is mostly ice- covered, except for four young craters that have erupted ash and lava flows in the last few thousand years. Parts of Takawangha's edifice are hydrothermally altered and may be unstable, and could produce localized debris avalanches. No historical eruptions are known from Sajaka or Takawangha; however, field work shows that recent eruptions have occurred and it is possible that historic eruptions attributed only to Tanaga may instead have come from these other vents.
The 130th Engineer Brigade (United States) has found the system to be "unstable, slow, not friendly and a major hindrance to operations". The equivalent system for the United States Navy was planned for initial deployment by 2015, and within a shipboard network called Consolidated Afloat Networks and Enterprise Services (CANES) by 2016. Some early testing was announced in 2009 aboard the aircraft carrier . A portion of the software, a distributed data framework for the DCGS integration backbone (DIB) version 4, was submitted to an open-source software repository of the Codice Foundation on GitHub.
By the late-17th century two other churches in old town Aalborg, Our Lady's Church (Danish:Vor Frue Kirke) and the Abbey Church (Danish:Klosterkirken), were deemed to be superfluous for the few thousand residents of Aalborg. Our Lady Church, the oldest of the three, was determined to be unstable, and it was torn down. By 1800 the Abbey Church and tower were dismantled, and the stone was used to expand nearby Aalborg Castle (Danish: Aalborghus). Budolfi Cathedral's tower is the only one of the original three church towers that are visible on the Aalborg city logo.
That is, if one of the eigenvalues of the system is not both controllable and observable, this part of the dynamics will remain untouched in the closed-loop system. If such an eigenvalue is not stable, the dynamics of this eigenvalue will be present in the closed-loop system which therefore will be unstable. Unobservable poles are not present in the transfer function realization of a state-space representation, which is why sometimes the latter is preferred in dynamical systems analysis. Solutions to problems of an uncontrollable or unobservable system include adding actuators and sensors.
For higher (lower) values of Reynolds number, the rightmost eigenvalue shifts into the positive (negative) half of the complex plane. Then, a fuller picture of the stability properties is given by a plot exhibiting the functional dependence of this eigenvalue; this is shown in the second figure. On the other hand, the spectrum of eigenvalues for Couette flow indicates stability, at all Reynolds numbers. However, in experiments, Couette flow is found to be unstable to small, but finite, perturbations for which the linear theory, and the Orr–Sommerfeld equation do not apply.
This artist's impression shows the dark photon A' decays into a pair of electron and positron. The dark photon is a spin-1 boson associated with a U(1) gauge field, which could be massless and behaves like electromagnetism. But, it could be unstable and massive, quickly decays into electron-positron pairs, and interact with electrons. The dark photon was first suggested in 2008 by Lotty Ackerman, Matthew R. Buckley, Sean M. Carroll, and Marc Kamionkowski to explain the 'g–2 anomaly' in experiment E821 at Brookhaven National Laboratory,.
The Swamp Thing and Constantine witnesses the effects of the Crisis: blood-red skies, and people and beasts from many different time periods, displaced into the present day. The pair were suddenly teleported to the Monitor's satellite by Alexander Luthor Jr. Constantine introduced the Swamp Thing to Alexander, who had formed a plan to ensure that reality survived the Crisis. Constantine promised that the Swamp Thing would likewise ensure that the spiritual realms survived the aftereffects of the Crisis. Constantine revealed that after the Crisis ended, reality would be unstable and vulnerable for a time.
A reciprocal inhibition also characterizes an electronic circuit known as the flip-flop. A flip-flop can assume one of two states, usually referred to as on or off. Thus, either the sleep neurons are active and inhibit the wakefulness neurons, or the wakefulness neurons are active and inhibit the sleep neurons, Because these regions are mutually inhibitory, it is impossible for neurons in both sets of regions to be active at the same time. This flip-flop, switching from one state to another quickly, can be unstable.
Over the years, a number of RAM expansion cartridges were developed for the Commodore 64 and 128. Commodore officially produced several models of RAM expansion cartridges, referred to collectively as the 17xx-series Commodore REUs. While these devices came in 128, 256, or 512 kB sizes, third-party modifications were quickly developed that could extend these devices to 2 MB, although some such modifications could be unstable. Some companies also offered services to professionally upgrade these devices. Typically, most Commodore 64 users did not require a RAM expansion.
In 2014, the dynamical simulation shown what the Kepler-32 planetary system have likely to undergone a substantial inward migration in the past, producing an observed pattern of lower-mass planets on tightest orbits.T. O. Hands, R. D. Alexander, W. Dehnen, "Understanding the assembly of Kepler's compact planetary systems", 2014 Additional yet unobserved gas giant planets on wider orbit are likely necessary for migration of smaller planets to proceed that far inward, although current planetary system would be unstable if additional planets are located closer than 8.7 AU from the parent star.
In everyday language, and often in materials science, a chemical substance is said to be "stable" if it is not particularly reactive in the environment or during normal use, and retains its useful properties on the timescale of its expected usefulness. In particular, the usefulness is retained in the presence of air, moisture or heat, and under the expected conditions of application. In this meaning, the material is said to be unstable if it can corrode, decompose, polymerize, burn or explode under the conditions of anticipated use or normal environmental conditions.
A prototype of the Servi-Car with rear suspension had been tested and was found to be unstable. The production model had its axle mounted directly to the frame with no suspension at all. Servi-Car with Hydra-Glide forks and disc brake Until 1957, the front forks of the Servi-Car were the springer-type leading-link forks used on the R-series and W-series solo motorcycles. From 1958 on, the Servi-Car changed neck stem length and inner diameter to use Hydra-Glide front forks.
One critique of majoritarianism is that systems without supermajority requirements for changing the rules for voting can be shown to likely be unstable. Among other critiques of majoritarianism is that most decisions in fact take place not by majority rule, but by plurality, unless the voting system artificially restricts candidates or options to two only. In turn, due to Arrow's paradox, it is not possible to have plurality voting systems with more than two options that retain adherence to both certain "fairness" criteria and rational decision-making criteria.
Although the engine had been successfully test fired, the first flight attempt blew up on the launching pad on 21 December 1933, a half a second after ignition. The cause was a buildup up of propellants before ignition of its 660-pound-thrust engine. Since the design was thought to be unstable, no further attempts were made, and efforts moved to the A2 design. The A-1 was too nose-heavy, and to compensate, the gyroscope system was moved to the middle of the A-2, between the oxygen and alcohol tanks.
The Baltimore Sun reported that the woman's actual name was Emily Jackson and described a woman of "great size and uncouth appearance." One of the deceased was Cornelius G. Cox, the civil engineer who had designed a culvert to replace the trestle, which was known to be unstable. After the collapse, the area was filled with earth and a graphite culvert placed over the stream, per his design. One of the surviving passengers was former Confederate Lieutenant General James Longstreet, who was returning from the 25th reunion of the Battle of Gettysburg.
A simple example of a shear flow is Couette flow, in which a fluid is trapped between two large parallel plates, and one plate is moved with some relative velocity to the other. Here, the strain rate is simply the relative velocity divided by the distance between the plates. Shear flows in fluids tend to be unstable at high Reynolds numbers, when fluid viscosity is not strong enough to dampen out perturbations to the flow. For example, when two layers of fluid shear against each other with relative velocity, the Kelvin–Helmholtz instability may occur.
Certain criteria need to be met for their formation. In most situations, water temperatures of at least are needed down to a depth of at least ; waters of this temperature cause the overlying atmosphere to be unstable enough to sustain convection and thunderstorms. Another factor is rapid cooling with height, which allows the release of the heat of condensation that powers a tropical cyclone. High humidity is needed, especially in the lower-to-mid troposphere; when there is a great deal of moisture in the atmosphere, conditions are more favorable for disturbances to develop.
However, telomeres do not fully prevent the loss of coding DNA at the terminal ends of linear chromosomes. In fact, the eventual loss of coding DNA in cellular lines within an organism is thought to play a role in senescence. Furthermore, evidence suggests that telomeres can be unstable and can be prone to mutations which lead to tumor development. Mutations which lead to the constitutive activity of telomerase can result in the loss of cellular mortality in tumor cell lines, which is associated with the development of cancer.
The highway department and local residents lobbied to have the entire route elevated on the basis that a ground-level roadway north of Manchac would negatively impact the swamp's ecosystem and also be unstable in the long term. Due to the cost element, this proposal was turned down by the Federal Highway Administration. In October 1974, however, the agency relented after overwhelming local opposition and an environmental impact survey were presented during a series of public hearings. Meanwhile, construction of the elevated I-55 had begun in November 1973.
The village is known for its association with Joseph Popov and his wife Vera Bogdanovskaya Popova. Vera was active in introducing both education and medicine into the village as well as being one of the first female chemists. She is also thought to be one of the first women to give her live for chemistry when she blew herself up whilst trying to create a chemical which is now known to be unstable. She is buried in the village and there is a monument to her that was built in 1897.
Novel Gas Research. Accessed April 26, 2009 Another notable example is the only naturally occurring isotope of bismuth, bismuth-209, which has been predicted to be unstable with a very long half-life, but has been observed to decay. Because of their long half-lives, such isotopes are still found on Earth in various quantities, and together with the stable isotopes they are called primordial isotope. All the primordial isotopes are given in order of their decreasing abundance on Earth.. For a list of primordial nuclides in order of half-life, see List of nuclides.
These films can be contaminated with significant carbon and hydrogen as silanol, and can be unstable in air. Pressures of a few torr and small electrode spacings, and/or dual frequency deposition, are helpful to achieve high deposition rates with good film stability. High-density plasma deposition of silicon dioxide from silane and oxygen/argon has been widely used to create a nearly hydrogen-free film with good conformality over complex surfaces, the latter resulting from intense ion bombardment and consequent sputtering of the deposited molecules from vertical onto horizontal surfaces.
Although most proteasomal substrates must be ubiquitinated before being degraded, there are some exceptions to this general rule, especially when the proteasome plays a normal role in the post-translational processing of the protein. The proteasomal activation of NF-κB by processing p105 into p50 via internal proteolysis is one major example. Some proteins that are hypothesized to be unstable due to intrinsically unstructured regions, are degraded in a ubiquitin-independent manner. The most well-known example of a ubiquitin- independent proteasome substrate is the enzyme ornithine decarboxylase.
Solo tuning strings can be tuned down a tone to play in orchestra pitch, but the strings often lack projection in orchestral tuning and their pitch may be unstable. Some contemporary composers specify highly specialized scordatura (intentionally changing the tuning of the open strings). Changing the pitch of the open strings makes different notes available as pedal points and harmonics. Berio, for example, asks the player to tune their strings E1–G1–D2–G2 in Sequenza XIVb and Scelsi asks for both F1–A1–D2–E2 and F1–A1–F2–E2 in Nuits.
Finally, in 1907 the Nevada legislature established a plan to redeem the debt at 65% of the outstanding obligation, with part of the debt undertaken by Clark County, newly created from the southern part of Lincoln County in 1909. The debt was retired in 1938, the same year that the new courthouse was built. The 1872 courthouse was alleged at the time to be unstable and deteriorating. Despite its state of disrepair, the courthouse survived almost forty years of abandonment and was restored in the 1970s to function as a local history museum.
Penny was born to Charles Widmore (Alan Dale) and an unnamed woman in England. She first met Desmond (Henry Ian Cusick) sometime in 1994 at a monastery in Scotland and asked him to help her deliver wine to Carlisle, in which he gladly agreed. Two years later, they were living together, in spite of her father's disapproval. Even though both were happy together, their relationship appeared to be unstable due to the disparity between the wealth of the two characters; Penny was an heiress while Desmond merely worked at a theatre company.
In both cases, this causes the diproton and dineutron nucleus to be unstable. The proton and neutron making up deuterium can be dissociated through neutral current interactions with neutrinos. The cross section for this interaction is comparatively large, and deuterium was successfully used as a neutrino target in the Sudbury Neutrino Observatory experiment. Diatomic deuterium (D2) has ortho and para nuclear spin isomers like diatomic hydrogen, but with differences in the number and population of spin states and rotational levels, which occur because the deuteron is a boson with nuclear spin equal to one.
The Dragon is built around the Motorola MC6809E processor running at 0.89 MHz. It was an advanced 8-bit CPU design, with limited 16-bit capabilities. It was possible to increase the speed of the computer by using POKE 65495,0 which accelerated the ROM-resident BASIC interpreter, but temporarily disabled correct functioning of the cassette/printer ports. Manufacturing variances mean that not all Dragons were able to function at this higher speed, and use of this POKE could cause some units to crash or be unstable, though with no permanent damage.
If the temperature of a semiconductor Fabry-Perot laser changes, the wavelengths that are amplified by the lasing medium vary rapidly. At the same time, the longitudinal modes of the laser also vary, as the refractive index is also a function of temperature. This causes the spectrum to be unstable and highly temperature dependent. At the important wavelengths of 1.55um and 1.3um, the peak gain typically moves about 0.4nm to the longer wavelengths as the temperature increases, while the longitudinal modes shift about 0.1nm to the longer wavelengths.
Paul Davies: About Time: Einstein's Unfinished Revolution This interior solution is not likely to be physical and considered as a purely mathematical artefact.Roy Kerr (Crafoord Prize Symposium in Astronomy): Spinning Black Holes. (Youtube, Timestamp 26m) While it is expected that the exterior region of the Kerr solution is stable, and that all rotating black holes will eventually approach a Kerr metric, the interior region of the solution appears to be unstable, much like a pencil balanced on its point.Penrose 1968 This is related to the idea of cosmic censorship.
A particular RAFT agent is only suitable for a limited set of monomers and the synthesis of a RAFT agent typically requires a multistep synthetic procedure and subsequent purification. RAFT agents can be unstable over long time periods, are highly colored and can have a pungent odor due to gradual decomposition of the dithioester moiety to yield small sulfur compounds. The presence of sulfur and color in the resulting polymer may also be undesirable for some applications; however, this can, to an extent, be eliminated with further chemical and physical purification steps.
After general elections on 28 August 1910, Republican party representation had grown only to 14 deputies in the Chamber of Deputies, the lower house of the Cortes. Even with support from other pro-republican parties, the Republicans were only able to muster closer to 40 seats in the Chamber, in comparison to the 120 pro-monarchist deputies. Nevertheless, these governments tended to be unstable, and during his reign Manuel II changed the government seven times. Militant Republicans and their allies in the Carbonária were not willing to remain in the shadows of the constitutional monarchy.
A negative interface energy suggests that the system should be unstable against maximizing the number of such interfaces, which was not observed in first experiments on superconductors, before the experiments of Shubnikov in 1936 where two critical fields were found. In 1952 observation of type-II superconductivity was also reported by Zavaritskii. As was later discussed by A. A. Abrikosov, these interfaces manifest as lines of magnetic flux passing through the material, turning a region of the superconductor normal. This normal region is separated from the rest of the superconductor by a circulating supercurrent.
Conditions around the Ust-Barguzin airfield were slightly more favorable than had been projected at the aircraft's height. At 11:02 the aircraft called in to report their location, but in violation of air rules, the crew instead called the air control tower at Ulan-Ude and did not report back to Ust-Barguzin. Additionally, they did not report their location or weather conditions. The aircraft's data finder, ARP-6, was found to be unstable, about which the Ust- Barguzin air tower warned Flight 498 well in advance.
It is expected that some continual improvement of experimental sensitivity will allow discovery of very mild radioactivity (instability) of some isotopes that are considered to be stable today. For an example of a recent discovery, it was not until 2003 that bismuth-209 (the only primordial isotope of bismuth) was shown to be very mildly radioactive, confirming theoretical predictions from nuclear physics that bismuth-209 would decay very slowly by alpha emission. Isotopes that are theoretically believed to be unstable but have not been observed to decay are termed as observationally stable.
The barrier protection feature triggered much increased reverse convertible issuances in UK in the early 2000s as well as in the European retail markets. By the early 2010s, the (barrier) reverse convertibles were also among the most popular structured products in US. While the barrier protection feature was beneficial for investors, for the issuers, managing and hedging relatively long-dated (e.g. 3~5 years) equity barrier risks were a serious challenge. The hedging parameters (Greeks) near the barrier could be unstable, and they could suddenly change which would lead to a massive increase in trading volumes in the process of hedging.
As weapons level up, their number of "Synthesis Points" increases, determining how many "spectrumized" items can be attached to it. Most items in this game can be broken down, or "spectrumized", which turns the item into a "SynthSphere" that can be attached to a weapon to raise specific stats, depending on its properties. Attachments cost synthesis points; when the weapon's points are depleted, no more attachments can be made until the weapon is leveled up and more synthesis points are attained. Weapons can also be spectrumized but the resulting SynthSphere will be unstable unless the weapon is level five or higher.
It is difficult to determine whether a star is currently evolving towards hotter temperature or returning to cooler temperatures, since the evolutionary tracks for stars with different masses overlap during the blue loops. Canopus lies on the warm side of the instability strip and does not pulsate like Cepheid variables of a similar luminosity. However its atmosphere does appear to be unstable, showing strong signs of convection. Canopus may not be massive enough for its fusion chain to reach iron and trigger a core collapse and subsequent supernova, instead eventually becoming a neon-oxygen white dwarf.
On a synoptic scale, isentropic analysis is associated with weather fronts: warm fronts are found where the wind crosses lines of a chosen potential temperature from lower heights to higher ones, while cold fronts are where the wind crosses descending heights. Synoptic clouds and precipitations can thus be better found with these areas of advection than with conventional isobaric maps. From a mesoscale point of view, an air parcel moving vertically will cross isolines of potential temperature and it will be unstable if the value of those lines decrease with altitude, or stable if they increase.
Under such conditions, the polyhedral crystal form will be unstable, it will sprout protrusions at its corners and edges where the degree of supersaturation is at its highest level. The tips of these protrusions will clearly be the points of highest supersaturation. It is generally believed that the protrusion will become longer (and thinner at the tip) until the effect of interfacial free energy in raising the chemical potential slows the tip growth and maintains a constant value for the tip thickness. In the subsequent tip-thickening process, there should be a corresponding instability of shape.
According to a letter from Goya to his friend Martín Zapater, this is where they first became acquainted when Julià sought Goya's recommendation as a mutual friend of Maella. At this time, Goya was beginning to suffer from deafness, so this may have helped form a sympathetic bond between them. In 1798, Goya received a major commission to create frescoes in the Royal Chapel of St. Anthony of La Florida, but his health continued to be unstable and he sometimes employed Julià as an assistant. A portrait by Goya indicates that the two were in contact until at least 1814.
The car immediately proved to be more competitive than its predecessor, consistently setting the quickest times in preseason testing. It was particularly fast in a straight line, thanks in part to the Mercedes power unit and in part to its low-drag design. At the first race in Australia, the car proved to be unstable in mixed conditions, but both drivers made it into Q3. In the race, Massa was taken out at the first turn but Bottas finished sixth – later promoted to fifth – despite a grid penalty and clipping the wall and cutting a tyre ten laps in.
In order for a boundary layer to be absolutely unstable (have an inviscid instability), it must satisfy Rayleigh's criterion; namely D^{2}U = 0 where D represents the y-derivative and U is the free stream velocity profile. In other words, the velocity profile must have an inflection point to be unstable. It is clear that in a typical boundary layer with a zero pressure gradient, the flow will be unconditionally stable; however, we know from experience this is not the case and the flow does transition. It is clear, then, that viscosity must be an important factor in the instability.
Grazier (2006), 44–45. In each system, there are five points where a body of negligible mass would remain stationary to the two much larger bodies in the system, the gas giant and its moon. These areas, known as Lagrange points, are classified by stability; while bodies at 60° angles to the gas giant would remain in the same location relative to the other objects in the system, the other three Lagrange points are meta-stable, having the tendency to be unstable in one direction. As the Halos are located at point , the installations must actively correct their orbits.Grazier (2006), 46.
Other methods mapping and profiling the methylome have been effective but are not without their limitations that can affect resolution, level of throughput, or experimental variations. For instance, RLGS is limited by the number of restriction sites in genome that can be targets for the restriction enzyme; typically, a maximum of ~4100 landmarks can be assessed. Bisulfite sequencing-based methods, despite possible single- nucleotide resolution, have a drawback: the conversion of unmethylated cytosine to uracil can be unstable. In addition, when bisulfite conversion is coupled with DNA microarrays to detect bisulfite converted sites, the reduced sequence complexity of DNA is a problem.
Drucker stability (also called the Drucker stability postulates) refers to a set of mathematical criteria that restrict the possible nonlinear stress- strain relations that can be satisfied by a solid material. The postulates are named after Daniel C. Drucker. A material that does not satisfy these criteria is often found to be unstable in the sense that application of a load to a material point can lead to arbitrary deformations at that material point unless an additional length or time scale is specified in the constitutive relations. The Drucker stability postulates are often invoked in nonlinear finite element analysis.
Fighting associated with the War of Independence would return near the end of the conflict. Military commanders Luis de Cortázar and Anastasio Bustamante joined forces with Agustín de Iturbide and took the city of Guanajuato on 8 July 1821, declaring the entire state independent of Spanish rule. In 1824, Guanajuato was officially proclaimed a state of Mexico by the Constitutional Congress of Mexico. Trolley passing in front of the San Diego Church in Guanajuato, 1907 The years after the end of the War of Independence were extremely unstable, and would continue to be unstable through most of the rest of the 19th century.
In June 2016, an estimated several thousand mayflies hatched in Sawyer Bay (within Sturgeon Bay). This was the result of an experiment to stock millions of eggs from the species Hexagenia limbata and Hexagenia bilineata in the lower Green Bay area in an attempt to reintroduce the species. The last mayfly from the genus Hexagenia had been collected in the lower Green Bay area in 1955. As mayfly populations can be unstable and not all stocking locations appeared to be successful, as of 2017 it was not yet known whether it would be possible for populations of Hexagenia mayflies to become self-sustaining.
In a typical general equilibrium model the prices that prevail "when the dust settles" are simply those that coordinate the demands of various consumers for various goods. But this raises the question of how these prices and allocations have been arrived at, and whether any (temporary) shock to the economy will cause it to converge back to the same outcome that prevailed before the shock. This is the question of stability of the equilibrium, and it can be readily seen that it is related to the question of uniqueness. If there are multiple equilibria, then some of them will be unstable.
While nuclear pasta has not been observed in a neutron star, its phases are theorized to exist in the inner crust of neutron stars, forming a transition region between the conventional matter at the surface and the ultradense matter at the core. Towards the top of this transition region, the pressure is great enough that conventional nuclei will be condensed into much more massive semi-spherical collections. These formations would be unstable outside the star, due to their high neutron content and size, which can vary between tens and hundreds of nucleons. This semispherical phase is known as the gnocchi phase.
The imperial standard yard of 1855 was found to be unstable and shortening by measurable amounts (Barbrow & Judson 1976, 16). Also, the mint pound was found to be “likewise unfit for use.” For several years before the Mendenhall order was actually issued, the Office of Weights and Measures was “practically forced” to use the metric standards because of their superior stability, and because they were better designed for carrying out precision comparisons. The Office found that the conversion tables in the 1866 law were satisfactory and used them to derive customary length and mass from the metric standards.
In her family's Spanish villa, Kimberly Prescott (Baxter), a young South African heiress of a diamond company, is grieving after her father's recent suicide, when she is taken aback by the arrival of a man (Todd) claiming to be her brother Ward, believed to have died in a car accident a few months ago. Kimberly calls the police but the man has a driving licence, passport and letter from the bank in the name of Ward Prescott. Even two photos from upstairs look like the man now in her house. The local police chief, Vargas, leaves, believing Kim to be unstable.
Lattice masts, introduced with the American s, seemed to be a robust solution and the Andrei Pervozvanny-class ships became the only Russian battleships fitted with them. They proved to be unstable and prone to vibration in service and the signal positions in them were regularly enveloped by funnel gases. Despite those drawbacks, the captain of Andrei Pervozvanny fiercely defended them and objected to all alternatives proposed by the NTC. On the day when Austria-Hungary declared war against Russia, the captain of Imperator Pavel I, who held an opposite opinion, volunteered to replace the masts in three days.
Overall, the Bronx–Whitestone Bridge was less prone to oscillation and critical failure, as it was not as flimsy as the Tacoma Narrows Bridge. After performing a series of experiments on the bridge's design, Ammann concluded that additional measures to stiffen the Whitestone Bridge were unnecessary. Even so, the public was scared by the fact that the two bridges were similar in design, and this led to a belief that the Whitestone Bridge might be unstable, as Moses later related. Shortly after the Tacoma Narrows Bridge collapse, Moses announced that steel cable stays would be installed on the bridge's towers to reduce oscillation.
Passivity, in most cases, can be used to demonstrate that passive circuits will be stable under specific criteria. Note that this only works if only one of the above definitions of passivity is used - if components from the two are mixed, the systems may be unstable under any criteria. In addition, passive circuits will not necessarily be stable under all stability criteria. For instance, a resonant series LC circuit will have unbounded voltage output for a bounded voltage input, but will be stable in the sense of Lyapunov, and given bounded energy input will have bounded energy output.
Penrose suggests that a superposition of two or more quantum states which have a significant amount of mass displacement ought to be unstable and reduce to one of the states within a finite time. He hypothesises that there exists a "preferred" set of states which could collapse no further, specifically the stationary states of the Schrödinger–Newton equation. A macroscopic system can therefore never be in a spatial superposition since the nonlinear gravitational self-interaction immediately leads to a collapse to a stationary state of the Schrödinger–Newton equation. According to Penrose's idea, when a quantum particle is measured, there is an interplay of this nonlinear collapse and environmental decoherence.
Polyaromatic hydrocarbons (PAHs), some of which are carcinogenic, come from the incomplete combustion of organic materials and are often found as a result of structural and wildland fires.IARC 2002 Safety hazards of fire cleanup include the risk of reignition of smoldering debris, electrocution from downed or exposed electrical lines or in instances where water has come into contact with electrical equipment. Structures that have been burned may be unstable and at risk of sudden collapse. Standard personal protective equipment for fire cleanup include hard hats, goggles or safety glasses, heavy work gloves, earplugs or other hearing protection, steel-toe boots, and fall protection devices.
When the beamformer is applied to the data, it produces an estimate of the power in a "virtual channel" at the source location. The extent to which the constraint-free MEG inverse problem is ill-posed cannot be overemphasized. If one's goal is to estimate the current density within the human brain with say a 5mm resolution then it is well established that the vast majority of the information needed to perform a unique inversion must come not from the magnetic field measurement but rather from the constraints applied to the problem. Furthermore, even when a unique inversion is possible in the presence of such constraints said inversion can be unstable.
The Texas Wildcat was briefly tested in the United States before shipment, being fitted with a different wing with a more conventional airfoil for operation out of the confined Curtiss Field. First flying on July 25, it demonstrated a speed of , with a speed of expected when fitted with the high speed racing wing. Both aircraft were then sent by ship to France, with no testing carried out on the high speed wing and Cactus Kitten unflown before sailing. Texas Wildcat was reassembled at the Morane-Saulnier factory with the high speed wing, but was found to be unstable at high speeds when flown by test pilot Roland Rohlfs.
Any swept wing tends to be unstable in the stall, since the rearward end stalls first causing a pitch-up force worsening the stall and making recovery difficult. This effect is more significant with forward sweep because the rearward end is the root and carries greater lift. However, if the aeroelastic bending is sufficient, it can counteract this tendency by increasing the angle of attack at the wing tips to such an extent that the tips stall first and one of the main characteristics of the design is lost. Such a tip stall can be unpredictable, especially where one tip stalls before the other.
Current monument to victims of the attack against Alfonso XIII Episodes such as the Morral affair showcased Spanish republican ability to galvanize popular support through political drama in an age of lethargy towards formal politics. It also spotlighted Spanish republican fissures that would become an identity crisis, as Nakens impatiently broke from the gradualist philosophy of the old generation of republicans and both republican factions showed intransigence towards cooperation. The affair appeared even to favor the republican moderates (Azcárate, Nicolás Salmerón), who condemned the radical, young republicans (Lerroux, Vicente Blasco Ibáñez) and made Nakens appear, by juxtaposition, to be unstable. This schism appeared to hasten the coming revolution.
Waves in the trade winds in the Atlantic Ocean—areas of converging winds that move along the same track as the prevailing wind—create instabilities in the atmosphere that may lead to the formation of hurricanes. The formation of tropical cyclones is the topic of extensive ongoing research and is still not fully understood. While six factors appear to be generally necessary, tropical cyclones may occasionally form without meeting all of the following conditions. In most situations, water temperatures of at least are needed down to a depth of at least ; waters of this temperature cause the overlying atmosphere to be unstable enough to sustain convection and thunderstorms.
The band's second EP, the That's Our Name...EP, was released in early 2004, and featured songs recorded throughout the previous year. In March of that year, the band became a duo again after the departure of Ballantine, who had decided he wasn't committed enough to the music. Typically, the lineup continued to be unstable throughout the entire year, as a month later they were joined by drummer Marcus Belassie, and in September by bassist/guitarist/vocalist Will Saunders. At Saunders' suggestion, the band began to practise at the Scout Hut in Shalford, notable for being the place where The Stranglers used to practise before they became well known.
Everest in September 2006 Although generally less popular than spring, Mount Everest has also been climbed in the autumn (also called the "post-monsoon season"). For example, in 2010 Eric Larsen and five Nepali guides summited Everest in the autumn for the first time in ten years. The first mainland British ascent of Mount Everest (Hillary was from New Zealand), which was also the first ascent via a face rather than a ridge, was the autumn 1975 Southwest Face expedition led by Chris Bonington. The autumn season, when the monsoon ends, is regarded as more dangerous because there is typically a lot of new snow which can be unstable.
The XM-736 8-inch projectile was a binary howitzer round that was designed to carry the nerve agent VX.Adams, Robert W. "CHEMICAL WARFARE IN FUTURE MILITARY OPERATIONS", Command and Staff College, United States Navy, via Globalsecurity.org, April 6, 1984, accessed January 3, 2009. After the suspension of the testing in 1982, models indicated the shell could be unstable in flight due to the liquid properties of VX.D'Amico,William P. , Jr. "Comments on the Flight Stability of the XM736 8-Inch Binary Projectile", (Abstract/Citation), October 1982, accessed January 3, 2009. However, instabilities were not observed during earlier testing, and it is unknown if instabilities in the shell were ever found.
Sixty of the S.1 were built and these were used for about 6 months on the Western Front by the Royal Flying Corps before it was relegated to training. Although initially intended for use in Home Defence operating from the UK, it was found to be inadequate for that too. It was reported to be unstable, and it was the aircraft Captain Louis Strange was flying in a combat with a German two-seater, when one of the oddest incidents of WW1 took place. He was changing a drum on his overhead Lewis gun, when the aircraft turned over - and he fell out.
The Nexus Memory Card is a third party version of the Visual Memory Unit that features four times the memory of a stock VMU with 800 blocks (4 megabit / 512 kilobytes) but lacks an LCD screen. The card is divided into 4 pages each with 200 blocks, each page can be selected using a button on the top left of the card. The Nexus Memory Card is slightly larger than the normal VMU and can be connected to a personal computer by USB, Parallel or Serial cable. A 3200 block (16 megabit / 2 megabytes) version of the Nexus is also available, but this model has been known to be unstable.
NZR C class of 1873 The 0-4-2T arrangement was used by two classes of locomotives operated by the New Zealand Railways Department. The first was the C class of 1873, originally built as an 0-4-0T. The class was found to be unstable at speeds higher than 15 mph, so by 1880 all members of the class had been converted to 0-4-2T to rectify this problem. The second and more notable 0-4-2T class, and the only one actually built as 0-4-2T, was the unique H class designed to operate the Rimutaka Incline on the Wairarapa Line.
Naturally occurring europium is composed of 2 isotopes, 151Eu and 153Eu, which occur in almost equal proportions; 153Eu is slightly more abundant (52.2% natural abundance). While 153Eu is stable, 151Eu was found to be unstable to alpha decay with a half- life of in 2007, giving about 1 alpha decay per two minutes in every kilogram of natural europium. This value is in reasonable agreement with theoretical predictions. Besides the natural radioisotope 151Eu, 35 artificial radioisotopes have been characterized, the most stable being 150Eu with a half-life of 36.9 years, 152Eu with a half-life of 13.516 years, and 154Eu with a half-life of 8.593 years.
This change in shape allows the binding of plasma protein Factor B, which allows Factor D to cleave Factor B into Ba and Bb. Bb remains bound to C3(H2O) to form C3(H2O)Bb. This complex is also known as a fluid-phase C3-convertase. This convertase, the alternative pathway C3-convertase, although only produced in small amounts, can cleave multiple C3 proteins into C3a and C3b. The complex is believed to be unstable until it binds properdin, a serum protein. The addition of properdin forms the complex C3bBbP, a stable compound which can bind an additional C3b to form alternative pathway C5-convertase.
Reduced glacial runoff can lead to insufficient stream flow to allow these species to thrive. Alterations to the ocean currents, due to increased freshwater inputs from glacier melt, and the potential alterations to thermohaline circulation of the World Ocean, may affect existing fisheries upon which humans depend as well. One major concern is the increased risk of Glacial Lake Outburst Floods (GLOF), which have in the past had great effect on lives and property. Glacier meltwater left behind by the retreating glacier is often held back by moraines that can be unstable and have been known to collapse if breached or displaced by earthquakes, landslides or avalanches.
In the 13th century a clerestory with six Early English lancet windows on each side was added to the nave to increase the amount of natural light, much of which had been lost when the aisles were added. Another Early English lancet window from this period survives in the north wall of the chancel. The south aisle proved to be unstable and was underbuilt in an attempt to stabilise it. At a later date, it is not known in which century, the south aisle was demolished. Slightly later in the 13th century the south chapel was added, and the easternmost arch of the south aisle became the entrance to the chapel.
Early on 25 September, while it Toulon, Liberté was destroyed by an accidental magazine explosion that killed nearly three hundred of her crew. A subsequent investigation revealed the cause to be unstable Poudre B propellant used by the French Navy at the time; stricter controls were put in place to reduce the likelihood of another accident. The three surviving members of the class spent the following three years in a similar pattern of training exercises and cruises around the Mediterranean. Following the assassination of Archduke Franz Ferdinand in June 1914 and during the ensuing July Crisis, the ships remained close to Toulon to be prepared for the possibility of war.
In its original form, the theory may be unstable, although this has only been shown in the case of the linearized version. In the weak field approximation where interaction between fields is not taken into account, NGT is characterized by a symmetric rank-2 tensor field (gravity), an antisymmetric tensor field, and a constant characterizing the mass of the antisymmetric tensor field. The antisymmetric tensor field is found to satisfy the equations of a Maxwell–Proca massive antisymmetric tensor field. This led Moffat to propose Metric Skew Tensor Gravity (MSTG), in which a skew symmetric tensor field postulated as part of the gravitational action.
In later editions of the book, Darwin traced evolutionary ideas as far back as Aristotle; the text he cites is a summary by Aristotle of the ideas of the earlier Greek philosopher Empedocles. Early Christian Church Fathers and Medieval European scholars interpreted the Genesis creation narrative allegorically rather than as a literal historical account; organisms were described by their mythological and heraldic significance as well as by their physical form. Nature was widely believed to be unstable and capricious, with monstrous births from union between species, and spontaneous generation of life. Cuvier's 1799 paper on living and fossil elephants helped establish the reality of extinction.
These black holes would be tiny, with a mass of around 10 micrograms. They would also be unstable enough to explode in a burst of particles within around 10−27 seconds. Theodore Tomaras, a physicist at the University of Crete in Heraklion, Greece, and his Russian collaborators hypothesize that these miniature black holes could explain certain anomalous observations made by cosmic-ray detectors in the Bolivian Andes and on a mountain in Tajikistan. In 1972, the Andean detector registered a cascade that was strangely rich in charged, quark-based particles; far more particles were detected in the bottom portion of the detector than in the top portion.

If there is a high reward or many benefits for the individual that initiated the cooperative behavior, mutualism should be selected for. When researchers investigated the co-evolution of cooperation and choice in a choosy host and its symbiont (an organism that lives in a relationship that benefits all parties involved), their model indicated that although choice and cooperation may be initially selected for, this would often be unstable. In other words, one cooperative partner will choose another cooperative partner if given a choice. However, if this choice is made over and over, variation is removed and this selection can no longer be maintained.
At the time, he referred to this device as the "pyrotron", but this name did not catch on. In a now-famous talk on fusion in 1954, Edward Teller noted that any device with convex magnetic field lines would likely be unstable, a problem today known as the flute instability. The mirror has precisely such a configuration, but continued experiments seemed to suggest that the experimental machines were not suffering from this problem, although there were many more practical issues limiting their performance. In Russia, the first small-scale mirror ("probkotron") was built in 1959 at the Budker Institute of Nuclear Physics in Novosibirsk, Russia.
The extent of the Roman Republic in 40 BC after Caesar's conquests Caesar was still deeply in debt, but there was money to be made as a governor, whether by extortionSee Cicero's speeches against Verres for an example of a former provincial governor successfully prosecuted for illegally enriching himself at his province's expense. or by military adventurism. Caesar had four legions under his command, two of his provinces bordered on unconquered territory, and parts of Gaul were known to be unstable. Some of Rome's Gallic allies had been defeated by their rivals at the Battle of Magetobriga, with the help of a contingent of Germanic tribes.
Following a failed bid for Mayor of Lima in 2014, placing fourth with 5.6% of the popular vote, Heresi was elected to the Peruvian Congress at the 2016 general election. During his congressional term, Heresi aligned with president Pedro Pablo Kuczynski, but the PPK parliamentary caucus proved to be unstable after the Kuczynski's downfall and Martín Vizcarra's accession to the presidency. Heresi was appointed as Minister of Justice and Human Rights in April 2018, but lasted only three months in office following the revelation of indirect involvement in the National Council of the Magistrature's scandal, in which Heresi was caught in communication with the disgraced Supreme Court justice, César Hinostroza. Heresi was eventually fired by Vizcarra in July 2018.
After Rabedeaux returned from a trip to Wisconsin, his behavior, which included becoming increasingly hostile and smelling of alcohol, attracted the attention of Heat owner Connor Nguyen, who warned him that should he cause another incident, he would be fired. Nguyen had hired Tony Garbelotto as an assistant and potential interim coach. During games, he appeared to be unstable and dizzy; during his final game against the Warriors, he attempted to draw a play, but was unable to, and Garbelotto had to explain the play. The day after the game, Rabedeaux was found by Eva in the kitchen with cuts on his arms and head, and died while in a local taxicab.
Bismuth (83Bi) has 41 known isotopes, ranging from 184Bi to 224Bi. Bismuth has no stable isotopes, but does have one very long-lived isotope; thus, the standard atomic weight can be given as . Although bismuth-209 is now known to be unstable, it has classically been considered to be a "stable" isotope because it has a half-life of approximately 2.01×1019 years, which is more than a billion times the age of the universe. Besides 209Bi, the most stable bismuth radioisotopes are 210mBi with a half-life of 3.04 million years, 208Bi with a half-life of 368,000 years and 207Bi, with a half-life of 32.9 years, none of which occur in nature.
Naturally occurring europium (63Eu) is composed of 2 isotopes, 151Eu and 153Eu, with 153Eu being the most abundant (52.2% natural abundance). While 153Eu is observationally stable, 151Eu was found in 2007 to be unstable and undergo alpha decay. The half-life is measured to be (4.62 ± 0.95(stat.) ± 0.68(syst.)) × 1018 y which corresponds to 1 alpha decay per two minutes in every kilogram of natural europium. Besides the natural radioisotope 151Eu, 36 artificial radioisotopes have been characterized, with the most stable being 150Eu with a half-life of 36.9 years, 152Eu with a half-life of 13.516 years, 154Eu with a half-life of 8.593 years, and 155Eu with a half-life of 4.7612 years.
Given that personality tends to be unstable until adulthood, researchers have been reluctant to conduct self-report personality measures on younger people. In line with this, most studies on the DTDD have been administering the questionnaire in university student or adult samples; however, a study has suggested that it is also applicable to use in high- school aged population as well. Consistent with studies investigating sex differences in scores of established measures of the dark triad traits, adult males tend to score higher on the DTDD than females, especially on the psychopathy subscale. Similar pattern of sex differences in the DTDD scores have been found among adolescents, however it is not as robust as the adult samples.
A parasexual cycle is initiated by the fusion of hyphae (anastomosis) during which nuclei and other cytoplasmic components occupy the same cell (heterokaryosis and plasmogamy). Fusion of the unlike nuclei in the cell of the heterokaryon results in formation of a diploid nucleus (karyogamy), which is believed to be unstable and can produce segregants by recombination involving mitotic crossing-over and haploidization. Mitotic crossing-over can lead to the exchange of genes on chromosomes; while haploidization probably involves mitotic nondisjunctions which randomly reassort the chromosomes and result in the production of aneuploid and haploid cells. Like a sexual cycle, parasexuality gives the species the opportunity to recombine the genome and produce new genotypes in their offspring.
Occasionally, nondisjunction of chromosomes occurs during division of a diploid nucleus, so that one of the daughter nuclei has one chromosome too many (2n+1) and the other has one chromosome too few (2n–1). Such nuclei with incomplete multiples of the haploid number are termed aneuploid, as they do not have even chromosome number sets such as n or 2n. They tend to be unstable and to lose further chromosomes during subsequent mitotic divisions, until the 2n+1 and 2n-1 nuclei progressively revert to n. Consistent with this, in E. nidulans (where normally, n=8) nuclei have been found with 17 (2n+1), 16 (2n), 15 (2n–1), 12, 11, 10, and 9 chromosomes.
The ground originally donated by the commune of Beaumont-Hamel to the Veterans of the 51st (Highland) Division, for the purposes of a memorial, was found to be unstable because of the many dugouts on the site. Lieutenant Colonel Nangle, the former Roman Catholic padre of the Royal Newfoundland Regiment who was largely responsible for the establishment of the Beaumont Hamel Newfoundland Memorial, offered the association a location overlooking Y Ravine within the boundaries of the site.Nicholson p. 518 Y Ravine was a forked gully (hence its name) which contained a formidably-fortified warren of defensive positions that had been the scene of a stunning victory by the Highland Division on 13 November 1916.
With the Brand New May uncertain of her place, May proposes she become a member of the Parker family; Mary Jane agrees, though Peter distrusts her and objects to the idea. May takes a walk, reflecting on how her parents, baby brother, and potential new twin sister have overcome so much and truly become "An Amazing Spider-Man Family".Amazing Spider-Girl No. 30 The following story-line sees Mayday and her clone (now named April) begin to steadily grow as crime-fighting partners, with April proving at times to be unstable and far more intense and ruthless than her "cousin" Mayday. At one point, April murders Tombstone when she believes him to have murdered May.
However, his is not the only case: reality seems to be unstable and some special people keep seeing visions of either how reality is supposed to be, or alternate worlds continually overlapping (all of this due to Kanjar Ro's substitution of Despero, in a bid to seize the power promised to him). Tomorrow Woman starts acting strangely and evaporates or duplicates, bus stations keep changing to airports, train stations, spaceports or Wild West saloons. Tarot goes to Opal City, where her cards show that she will be helped. There, she finds Charity O'Dare, a fellow tarot mystic, and is instructed on the power of the Worldsoul-a bond linking a human to the living spirit of Earth.
Lawlessness during wars and civil conflicts can create a culture of impunity towards human rights abuses of civilians. Among some armies, looting of civilian areas is considered a way for soldiers to supplement their often meager income, which can be unstable if soldiers are not paid on time. Some militias that cannot afford to adequately pay their troops promote pillaging as a compensation for victory, and rape of civilians can be seen as a reward for winning battles. According to UNICEF, "systematic rape is often used as a weapon of war in ethnic cleansing," having been used in various armed conflicts throughout the twentieth century alone, including Bosnia and Herzegovina, Cambodia, Uganda, and Vietnam.
It will continue to librate around for at least 70,000 years and will remain a Uranus co-orbital for up to three million years before becoming a centaur. is thus a temporary Uranus trojan—a centaur captured some time ago. Uranus trojans are generally expected to be unstable and none of them are thought to be of primordial origin. A simulation led to the conclusion that at any given time, 0.4% of the centaurs in the scattered population within 34 AU would be Uranus co-orbitals, of which 64% (0.256% of all centaurs) would be in horseshoe orbits, 10% (0.04%) would be quasi- satellites, and 26% (0.104%) would be trojans (evenly split between the and groups).
If this protein promotes cell cycle progression (Start in the case of yeast), then it will link cell cycle progression to translation rate and, therefore, cell size. Importantly, this protein must be unstable, so that its levels depend on its current translation rate, rather than the rate of translation over time. Furthermore, since the cell grows in volume as well as mass, the concentration of this size sensor will remain constant with growth, so its activity must be compared against something that does not change with cell growth. Genomic DNA was suggested as such a standard early on, because it is (by definition) present in a constant quantity until the start of DNA replication.
While some star systems could be resolved to a simple pair of bodies most will not. The systemic software implements several ways of calculating orbital mechanics – from the simplistic Keplerian laws to an implementation of Runge–Kutta methods. Results one obtains can be uploaded and are analyzed independently for goodness of fit and stability and are posted among the proposed solutions for that system. If a result is found to be unstable it is removed from the list of candidate solutions, though it is possible a particular system really is in a period of transition and instability (presumed to be a rare condition) so great that planets would be ejected from the system.
The tailings dam was considered to be unstable and is leaching various minerals, including heavy metals, into neighbouring waterways and this adversely affected the stream ecology. According to Environment Waikato, the Tui mine had three major environmental impacts; # The heavy metals lead and cadmium were leaching from the tailings dam into the Tunakohoia stream, which flows through land managed by the Department of Conservation and through the centre of the town of Te Aroha. Four years after the mine closed, the Te Aroha town water supply was found to be contaminated with heavy metals leaching from the tailings. # The separate Tui catchment was also contaminated with heavy metals from the tailings dam.
In social psychology, signed graphs have been used to model social situations, with positive edges representing friendships and negative edges enmities between nodes, which represent people. Then, for example, a positive 3-cycle is either three mutual friends, or two friends with a common enemy; while a negative 3-cycle is either three mutual enemies, or two enemies who share a mutual friend. According to balance theory, positive cycles are balanced and supposed to be stable social situations, whereas negative cycles are unbalanced and supposed to be unstable. According to the theory, in the case of three mutual enemies, this is because sharing a common enemy is likely to cause two of the enemies to become friends.
The VVD became the largest party with 31 seats, closely followed by the PvdA with 30 seats. The big winner of the 2010 elections was Geert Wilders, whose right wing PVV, the ideological successor to the LPF, more than doubled its number of seats. Negotiation talks for a new government resulted in a minority government, led by VVD (a first) in coalition with CDA, which was sworn in on 14 October 2010. This unprecedented minority government was supported by PVV, but proved ultimately to be unstable, when on 21 April 2012, Wilders, leader of PVV, unexpectedly 'torpedoed seven weeks of austerity talks' on new austerity measures, paving the way for early elections.
Although the results were fruitful, the theory also apparently implied the existence of negative energy states, which would cause atoms to be unstable, since they could always decay to lower energy states by the emission of radiation. The prevailing view at the time was that the world was composed of two very different ingredients: material particles (such as electrons) and quantum fields (such as photons). Material particles were considered to be eternal, with their physical state described by the probabilities of finding each particle in any given region of space or range of velocities. On the other hand, photons were considered merely the excited states of the underlying quantized electromagnetic field, and could be freely created or destroyed.
The Zumwalt-class destroyer reintroduces the tumblehome hull form, a hull form not seen to this extent since the Russo-Japanese War in 1905. It was originally put forth in modern steel battleship designs by the French shipyard Forges et Chantiers de la Méditerranée in La Seyne, Toulon. French naval architects believed that tumblehome, in which the beam of the vessel narrowed from the waterline to the upper deck, would create better freeboard, greater seaworthiness, and, as Russian battleships were to find, would be ideal for navigating through narrow constraints (e.g. canals).Forczyk. p. 18, 76 On the downside, the tumblehome battleships leaked – partly due to their riveted construction – and could be unstable, especially when turning at high speed.
The rotor blades were to be deployed before reentry; some questions were raised about whether the blades would survive until landing. The initial plan was to have them almost vertical, but that was found to be unstable as they needed to drop lower and lower and spin faster for stability, the heating rates went up dramatically and the air flow became more head on. The implication of that was that the blades went from a lightly heated piece of hardware to one that either had to be actively cooled or made of SiC or other refractory material. The idea of popping out the blades became much more attractive at this point, and initial studies were made for that option.
In March 2011, Qian et al. claimed the presence of two planets, though the proposed orbits were subsequently shown to be unstable. and on orbits determined from a more thorough and precise analysis of the observational data. Indeed, it seems likely that the signal that was interpreted as being the result of planetary companions might be instead the result of not well- studied interactions between the white dwarf and its red dwarf companion: as of 2014 all proposed orbital solutions have been refuted and it appears that the full set of timing measurements is inconsistent with any 1, 2 or 3-planet system due to poor fits to the data and unstable orbital configurations.
Since the 19th century, the hypothesis has occasionally been put forward that the Roman inscriptions were created by movable type printing.Lanciani 1881, p. 416, A recent investigation by the typesetter and linguist Herbert Brekle, however, concludes that all material evidence points to the use of common text stamps.: Brekle describes the manufacturing method as follows: Lead pipe stamp of the Legio XIV Gemina Brekle lists the following reasons for the employment of stamps and against that of movable type: for printing on lead sheets the way the Romans created them, it would be much more practical to use single stamp blocks than sets of individual letters, since the latter would be unstable and would have required a clamp or some similar mechanism to maintain the necessary cohesion.
The History of the Keighley and Worth Valley Railway by R.O.T. Povey (pages not timbered) published in 1968 The deviation was built as a condition of the buy out of the Keighley and Worth Valley Railway by the Midland Railway. The need for the deviation was to avoid a large wooden trestle viaduct that crossed a mill pond, as the locals believed the viaduct was unsafe, and supposedly many alighted at Oakworth and continued on foot to Haworth to avoid crossing the viaduct. The original design for the deviation was to skirt the mill pond then through a cutting to rejoin the original formation. However, during construction the material in the cutting proved to be unstable, resulting in the construction of the short Mytholmes Tunnel.
In theory, though, all isotopes with an atomic number greater than 66 are supposed to be unstable to alpha decay. Conversely, all elements with atomic numbers are less than or equal to 66 (except Tc, Pm, Sm and Eu) have at least one isotope that is theoretically energetically stable to all forms of decay (with the exception of proton decay, which has never been observed, and spontaneous fission, which is theoretically possible for elements with atomic numbers greater than 40). Like all other elements, the elements of the boron group have radioactive isotopes, either found in trace quantities in nature or produced synthetically. The longest-lived of these unstable isotopes is the indium isotope 115In, with its extremely long half-life of .
All sorts of situations and events can cause loneliness, especially in combination with certain personality traits for susceptible individuals. For example, an extroverted person who is highly social is more likely to feel lonely if they are living some where with a low population density, with fewer people for them to interact with. Loneliness can sometimes even be caused by events that might normally be expected to alleviate it: for example the birth of a child ( if there is significant postpartum depression ) or after getting married (especially if the marriage turns out to be unstable, overly disruptive to previous relationships, or emotionally cold.) In addition to being impacted by external events, loneliness can be aggravated by pre-existing mental health conditions like chronic depression and anxiety.
The Roman Republic in 40 BC after Caesar's conquests Caesar was still deeply in debt, and there was money to be made as a provincial governor, whether by extortionSee Cicero's speeches against Verres for an example of a former provincial governor successfully prosecuted for illegally enriching himself at his province's expense. or by military adventurism. Caesar had four legions under his command, two of his provinces, Illyricum and Gallia Narbonensis, bordered on unconquered territory, and independent Gaul was known to be unstable. Rome's allies the Aedui had been defeated by their Gallic rivals, with the help of a contingent of Germanic Suebi under Ariovistus, who had settled in conquered Aeduan land, and the Helvetii were mobilising for a mass migration, which the Romans feared had warlike intent.
L-forms can be generated in the laboratory from many bacterial species that usually have cell walls, such as Bacillus subtilis or Escherichia coli. This is done by inhibiting peptidoglycan synthesis with antibiotics or treating the cells with lysozyme, an enzyme that digests cell walls. The L-forms are generated in a culture medium that is the same osmolarity as the bacterial cytosol (an isotonic solution), which prevents cell lysis by osmotic shock. L-form strains can be unstable, tending to revert to the normal form of the bacteria by regrowing a cell wall, but this can be prevented by long-term culture of the cells under the same conditions that were used to produce them - letting the wall-disabling mutations to accumulate by genetic drift.
There was considerable opposition to building on the tidelands, in part because it was felt such a building would be unstable in an earthquake, but it was stabilized by 30-foot-long steel pilings driven in the ground and other measures. Some of the steel pilings were alternated in a manner designed to bear lateral stress; this was a novel design and was considered to be "on the cutting edge of engineering developments." Engineering issues and the Great Depression delayed the start of construction until 1935, when $1 million of Works Progress Administration funds were assigned to the project (combined with $750,000 of local funds). President Franklin Delano Roosevelt dedicated the building on July 16, 1938 before a crowd estimated as 25,000 people.
Fallout from the affair appeared to favor the republican moderates (Gumersindo de Azcárate, Nicolás Salmerón), who condemned the radical, young republicans (Alejandro Lerroux, Vicente Blasco Ibáñez) and made Nakens appear, by juxtaposition, to be unstable. This schism appeared to hasten the coming revolution. In hindsight, historian Enrique Sanabria proposes Nakens as a tragic parable: that Nakens' decision to hide Morral reflected a willingness to work with revolutionaries that, when pronounced, would ostracize him from his more moderate republican colleagues. Nakens was shortsighted to believe that his messages of egalitarianism, democracy, and cultural revolution would not appeal to the leftists he sought to avoid, and his popularity within anarchist and radical circles reflected anticlericalism's status as a uniting force across the left.
In 1938, she became a Huff Research Fellow at Bryn Mawr College, which allowed her to receive her PhD for her thesis on nuclear physics, "Photoelectric Cross Section of the Deuteron". She subsequently took up a teaching position at the University of Tennessee in 1939, becoming an assistant professor in 1941. At a conference in New York in 1938, Way presented a paper, "Nuclear Quadrupole and Magnetic Moments", in which she examined deformation of a spinning atomic nucleus under three models, including Niels Bohr's liquid drop model. She followed this up with a closer examination of the liquid drop model in a paper entitled "The Liquid- Drop Model and Nuclear Moments", in which she showed that the resulting cigar- shaped nucleus could be unstable.
61% of the nucleons in uranium-235 are neutrons), the initial fission products are often more neutron-rich than stable nuclei of the same mass as the fission product (e.g. stable zirconium-90 is 56% neutrons compared to unstable strontium-90 at 58%). The initial fission products therefore may be unstable and typically undergo beta decay to move towards a stable configuration, converting a neutron to a proton with each beta emission. (Fission products do not decay via alpha decay.) A few neutron-rich and short-lived initial fission products decay by ordinary beta decay (this is the source of perceptible half life, typically a few tenths of a second to a few seconds), followed by immediate emission of a neutron by the excited daughter-product.
The impedance values inverted from the algorithm represents the average value in the discrete interval. Considering that inverse modeling problem is only theoretically solvable when the number of discrete intervals for sampling the properties is equal to the number of observation in the trace to be inverted, a high-resolution sampling will lead to a large matrix which will be very expensive to invert. Furthermore, the matrix may be singular for dependent equations, the inversion can be unstable in the presence of noise and the system may be under-constrained if parameters other than the primary variables inverted for, are desired. In relation to parameters desired, other than impedance, Cooke and Schneider (1983) gives them to include source wavelet and scale factor.
As of 2011, three extrasolar planets have been found to orbit the star. Announced on the first of November 1999, the first planet (HD 37124 b) was discovered orbiting its parent star around the inner edge of the habitable zone, causing the planet to have a somewhat similar insolation to that of Venus. A second planet became apparent by 2003, thought to orbit in a 1940 days on an eccentric orbit, but this was subsequently found to be unstable. Solving this, a three-planet solution was announced in 2005: this contained a second planet (HD 37124 c) orbiting at the outer edge of the habitable zone with an insolation similar to that of Mars, and a third planet, (HD 37124 d).
Dima and Inga, a girl he knew on Earth, propose the establishment of a Confederation of islands as the way to stop the Game, and get support among their peers. Some knights refuse to join the Confederation and are killed when they do not surrender to the conquerors. However, the Confederation, even realized, proves to be unstable and is doomed from the beginning: though most want to return home, some only want power for themselves... Also, this attempt was not the first: Dima and his friends discover a hidden room with remains of children who got on islands during the Second World War and locked themselves in, when their attempt of Union of Islands collapsed because of betrayal. But the heroes also find old weapons in this room, including dynamite.
Configurations of classical charged particles orbiting one another are unstable due to losses of energy by electromagnetic radiation. For quite some time, this led to the puzzling question of why matter stays together, as much evidence was found that matter was held together electromagnetically, but static configurations would be unstable, and electrodynamic configurations would be expected to radiate energy and decay. These questions eventually pointed the way to quantum mechanical explanations of the structure of the atom, where the existence of stationary (non-radiative) states in which the electron has a nonzero momentum (and therefore is not actually static) resolves the above conundrum at a fundamental level. At a more practical level, it can be said that the Pauli exclusion principle and the existence of discrete electron orbitals are responsible for making bulk matter rigid.
People in the future may even experience never-ending "gradients of bliss". Such decentralized scenarios may be unstable in the long run, as the greediest elements of the superintelligent classes would have both the means and the motive to usurp the property of the unenhanced classes. Even if the mechanisms for ensuring legal property rights are both unbreakable and loophole-free, there may still be an ever-present danger of humans and cyborgs being "tricked" by the cleverest of the superintelligent machines into unwittingly signing over their own property. Suffering may be widespread, as sentient beings without property may die, and no mechanism prevents a being from reproducing up until the limits of his own inheritable resources, resulting in a multitude of that being's descendants scrabbling out an existence of minimal sustenance.
A black string is a higher dimensional (D>4) generalization of a black hole in which the event horizon is topologically equivalent to S2 × S1 and spacetime is asymptotically Md−1 × S1. Perturbations of black string solutions were found to be unstable for L (the length around S1) greater than some threshold L′. The full non-linear evolution of a black string beyond this threshold might result in a black string breaking up into separate black holes which would coalesce into a single black hole. This scenario seems unlikely because it was realized a black string could not pinch off in finite time, shrinking S2 to a point and then evolving to some Kaluza–Klein black hole. When perturbed, the black string would settle into a stable, static non-uniform black string state.
While on the road, the relationship of the couple is revealed to be unstable, as Del Rey is forced to kiss her boyfriend while expressing sadness. The trip intercuts with scenes of the couple staying at a luxurious hotel, where they are seen lying on a bed together with the boyfriend ominously holding Del Rey's throat at one point. As Del Rey makes her way out the hotel, the scene cuts back to an apparent car accident, with the singer's bloodied corpse being carried by her lover as a huge fire burns behind them. Also, the video intercuts scenes shot at the Palace of Fontainebleau, showing Del Rey sitting on a throne with tigers beside her in the Trinity Chapel or walking in the Gallery of Francis I. The video ends with the opening scene.
Image of Tsarnaev on the cover of Rolling Stone Tsarnaev was the subject of a cover story for an August 2013 issue of Rolling Stone entitled "The Bomber: How a Popular, Promising Student Was Failed by His Family, Fell into Radical Islam and Became a Monster." The magazine drew heavy criticism for the flattering photo of Tsarnaev on the issue's cover. Boston Mayor Tom Menino wrote that the cover "rewards a terrorist with celebrity treatment." Massachusetts State Police sergeant Sean Murphy said that "glamorizing the face of terror is not just insulting to the family members of those killed in the line of duty, it also could be an incentive to those who may be unstable to do something to get their face on the cover of Rolling Stone magazine".
Carl then meets with Gwen and her father, Jim Hunt, and tells them what happened with Pastor Dan and Jerry, but neither believes him, thinking it was a dream or an "acid flashback". Realizing they will tell Pastor Dan, Carl goes to Blaylock's college, where he runs into Honey Foster, a friend from his Deadhead days who became campus security and met him at the debate. He asks her to turn in the footage from a security camera that would have seen him and Pastor Day enter, but finds that the footage has been altered to erase them - apparently by Jerry, who worked at the campus as a video technician. Meeting with Gwen and Jim, Pastor Day convinces them that Carl may be unstable and will react violently if he is caught by the police.
On the other hand, the Social Liberals and the Danish People's Party welcomed the announcement, while the Red–Green Alliance refused to support such a government. Pia Kjærsgaard, speaker of the Folketing and former leader of the Danish People's Party, called for a majority government between Venstre, the Social Democrats, and the Danish People's Party, as an SV-government would be unstable and could give the Social Liberals too much influence on the immigration policy. On 4 June, the day before the election, Løkke Rasmussen gave up on his plans to form a centre-right government, saying it was no longer "realistic". He instead made it his first priority to create a government across the political middle, in order to keep the right- and left wing away from power.
The existence of the planet was first evidenced in data collected by the Kepler spacecraft in 2012. However, the light curve of the star, a graph of its stellar flux versus time, showed that while there were regular drops in stellar flux approximately every 15 hours, the amount of light being blocked covered a wide range, from 0.2% to 1.3% of the starlight being blocked. Saul Rappaport and collaborators proposed various possible phenomena which may have caused the anomalies in the light curve, including two planets orbiting each other, and an eclipsing binary orbiting the star in a larger triple-star system. However, the authors found the hypothetical binary planet system to be unstable and the latter scenario to be poorly supported by the data collected by Kepler.
For larger fractional fillings, the Wigner crystal was thought to be unstable relative to the fractional quantum Hall effect (FQHE) liquid states. The recent observation of a Wigner crystal in the immediate neighborhood of the large fractional filling ν=1/3 was unexpected, and has led to a new understanding (based on the pinning of a rotating Wigner molecule) for the interplay between quantum-liquid and pinned-solid phases in the lowest Landau level. Another experimental realisation of the Wigner crystal occurs in single electron transistors with very low currents, where a 1D Wigner crystal will form. The current due to each electron can be directly detected experimentally. (see also the Nature review article here Additionally, experiments using quantum wires - short quantum wires are sometimes referred to as ‘quantum point contacts’, (QPCs) - have also led to suggestions of Wigner crystallization in 1D systems.
The privately revised expedition schedule required Fram to leave Norway in August 1910 and sail to Madeira in the Atlantic, its only port of call. From there the ship would proceed directly to the Ross Sea in Antarctica, heading for the Bay of Whales, an inlet on the Ross Ice Shelf (then known as the "Great Ice Barrier") where Amundsen intended to make his base camp. The Bay of Whales was the southernmost point in the Ross Sea to which a ship could penetrate, closer to the Pole than Scott's intended base at McMurdo Sound. In 1907–09 Shackleton had considered the ice in the Bay of Whales to be unstable, but from his studies of Shackleton's records Amundsen decided that the Barrier here was grounded on shoals or skerries, and would support a safe and secure base.
The ring swirling around Saturn consists of chunks of ice and dust. The little dark spot on Saturn is the shadow from Saturn's moon Enceladus. There are three ways that thicker planetary rings (the rings around planets) have been proposed to have formed: from material of the protoplanetary disk that was within the Roche limit of the planet and thus could not coalesce to form moons, from the debris of a moon that was disrupted by a large impact, or from the debris of a moon that was disrupted by tidal stresses when it passed within the planet's Roche limit. Most rings were thought to be unstable and to dissipate over the course of tens or hundreds of millions of years, but it now appears that Saturn's rings might be quite old, dating to the early days of the Solar System.
The operational service of the Mi-10 was of moderate success, being distributed mainly to units of the VVS (Voyenno-Vozdushnyye Sily - Soviet Air Force) which already operated the Mi-6. Operations with no load were found to be unstable, and the best procedure for take-off was found to be a rolling take-off, which usually also resulted in nose-wheel shimmy when lightly loaded. The main mission of the early Mi-10 virtually evaporated with the improvements in contemporary ballistic missiles; thus the majority of the long-legged variants were converted to Mi-10PP, (or mi-10P), airborne Electronic Counter-Measures helicopters, carrying a large ST-900 Step' (Step' - Steppe) ECM pod under the fuselage mounted on a pallet. Other Mi-10 long legged aircraft were converted to carry out a wide variety of missions but usually only as single prototypes.
The journal's "most famous episode" (according to Villani) concerns Henri Poincaré, who won a prize offered in 1887 by Oscar II of Sweden for the best mathematical work concerning the stability of the Solar System by purporting to prove the stability of a special case of the three-body problem. This episode was rediscovered in the 1990s by Daniel Goroff, in his preface to the English translation of "Les méthodes nouvelles de la mécanique céleste". by June Barrow-Green and K.G. Andersson.. The prized or lauded paper was to be published in Acta Mathematica, but after the issue containing the paper was printed, Poincaré found an error that invalidated his proof. He paid more than the prize money to destroy the print run and reprint the issue without his paper, and instead published a corrected paper a year later in the same journal that demonstrated that the system could be unstable.
They are most frequent and most ecologically significant in island systems, where insect and sometimes also bird populations may be unstable and less species-rich. Adaptation to a lack of animal food and of predation pressure, might therefore favour reptiles becoming more herbivorous and more inclined to feed on pollen and nectar. Most species of lizards in the families that seem to be significant in pollination seem to carry pollen only incidentally, especially the larger species such as Varanidae and Iguanidae, but especially several species of the Gekkonidae are active pollinators, and so is at least one species of the Lacertidae, Podarcis lilfordi, which pollinates various species, but in particular is the major pollinator of Euphorbia dendroides on various Mediterranean islands. Mammals are not generally thought of as pollinators, but some rodents, bats and marsupials are significant pollinators and some even specialise in such activities.
It would give the British an occupation zone that was physically close to the UK and on the coast, making it easier to resupply it from the UK. It was also hoped that the old domination of Prussia would be undermined. The United States envisaged a very different division of Germany, with a large American zone in the north, a smaller zone for the Soviets in the east (the American and Soviet zones meeting at Berlin) and a smaller zone for the British in the south. President Franklin D. Roosevelt disliked the idea of a U.S. occupation zone in the south, because its supply routes would depend on access through France, which it was feared would be unstable following its liberation. One version of events (of at least two distinct versions of the circumstances of American approval), has it that to forestall anticipated American objections, the British proposal was presented directly to the EAC without the prior agreement of the Americans.
The dihedral angles (φ, ψ) are about (–120°, 115°) in parallel sheets. It is rare to find less than five interacting parallel strands in a motif, suggesting that a smaller number of strands may be unstable, however it is also fundamentally more difficult for parallel β-sheets to form because strands with N and C termini aligned necessarily must be very distant in sequence . There is also evidence that parallel β-sheet may be more stable since small amyloidogenic sequences appear to generally aggregate into β-sheet fibrils composed of primarily parallel β-sheet strands, where one would expect anti-parallel fibrils if anti-parallel were more stable. In parallel β-sheet structure, if two atoms C and C are adjacent in two hydrogen-bonded β-strands, then they do not hydrogen bond to each other; rather, one residue forms hydrogen bonds to the residues that flank the other (but not vice versa).
National Bureau of Standards, Refinement of values for the yard and pound There were two factors that influenced the order: for one, the imperial standard yard of 1855 had been found to be unstable and shortening by measurable amounts. Secondly, the United States was a co-signee of the Treaty of the Metre of 1875 and had received two meter prototypes on which to base a new fundamental standard. In the United Kingdom, a similar situation developed with the Weights and Measures Act of 1897 legalizing the metric system, and Order in Council 411 (1898) defining the meter and kilogram in terms of the yard and pound. As a practical matter the British definitions were reversed, resulting in a de facto definition of the imperial yard as 36/39.370113 meter. In the 1890s, Albert Michelson began conducting experiments in interferometry that led in 1903 to demonstrating the feasibility of using light waves as units of linear measurement.
Nonetheless, local sailors were participants so much in the first voyage of Columbus, where names appear as Talafar, Vizcaino and Alonso Rodríguez, as whom in the Second Columbian expedition, where they went also in the caravel La Niña, the sailor Rodrigo Calafar from Cartaya, in the caravel San Juan, Alonso Rodríguez and in the caravel Cardera, Juan Vizcaíno. The still insecure population moved to Trinitarians of Barefoot Mercy, order dedicated to the redemption of captives, to settle in the locality as it had in other nearby locations. Nonetheless, the settlements continue to be unstable disappearing ancient medieval villages such as San Miguel de Arca de Buey and population decrease in the core as consequence of a plague epidemic in 1602. This critical stage contrasts with that of later centuries, especially when in the 18th century, there develops great part of Cartaya's current urban plot in spite of the presumable destructions (as in the conventual building) of the 1755 Lisbon earthquake.
Many of the ironworks of the Merthyr and Dowlais areas were declining steeply or indeed closing in this period, and the B&MR; network's dependency on those industries made it extremely vulnerable. A traffic pooling arrangement for mineral traffic between the GWR and the London Midland and Scottish Railway was agreed in 1933, and this resulted in a switch for much traffic to more efficient routes, avoiding the long and difficult climb through the Brecon Beacons and Talyllyn, and this reduced the volume of traffic. The hillside above New Tredegar had shown itself to be unstable resulting in temporary closure of the line in 1916, and more serious slips took place in September 1928, April 1929 and April 1930. This resulted in the closure of the upper portion of the branch from 14 April 1930; the only working colliery on the affected section could equally well be served by the former Rhymney Railway branch.
Several alternative universe versions of the character exist: A Legends of the Dead Earth story set in the far future features a former media-star Bizarro who owns an amusement park and who fights against his own obsolescence.Action Comics Annual #8 (1996) The Elseworlds one-shot The Superman Monster (1999), essentially a Frankenstein pastiche, features a monstrous copy of Bizarro created by a Viktor Luthor based on the remains of the infant Kal-El, who died upon arrival.The Superman Monster #1 In the limited series JLA: The Nail, having found Kal-El's ship, Lex Luthor uses DNA samples to create Bizarro-like duplicates, which he disguises as the "Liberator" robots to hunt down the supposedly rogue metahumans.JLA: The Nail #3 While the Liberators possess Superman's powers in terms of strength and speed, their genetic structure proves to be unstable, to the point that they collapse after sustaining even minor damage in combat with metahuman foes, relying on stealth and superior numbers to overwhelm their prisoners.
As it turned out, the holding of the monarchy would be unstable in itself because, although Maria da Glória's reign as Maria II began on 2 May 1826, political and civil unrest on various issues and the regent, Isabel Maria's poor health led to a decree being issued to Miguel in May 1827 asking him to return and take on the role of regent. Miguel agreed to fulfil all these conditions, at least as he led others to believe, But on his return to Lisbon on 22 February 1828, with widespread celebrations, the cheers were, "Viva o Senhor D. Miguel I nosso rei absoluto" (Long live the Lord D. Miguel, our Absolute King). In the same year, the queen was taken away from Portugal, travelling to various countries and not returning to Lisbon until 1833. William Essex (1784–1869) after the miniature by William Ross (1794–1860) painted in Lisbon in 1852.
In the western North Pacific, there are strong reciprocal relationships between the areas of formative tropical cyclones and that of the lower tropospheric monsoon troughs and the tropical upper tropospheric trough. Tropical cyclone movement can also be influenced by TUTT cells within of their position, which can lead to non- climatological tracks, such as eastward movement within the tropics or westward movement in an area where the Westerlies normally dominate. Normally, an ocean temperature of 26.5 °C (79.7 °F) spanning through a depth of at least is one of the six requirements needed to maintain the special mesocyclone that is the tropical cyclone. Cooler air temperatures at a higher altitude (e.g., at the 500 hPa level, or 5.9 km) can lead to tropical cyclogenesis at lower water temperatures than normal, as a certain lapse rate is required to force the atmosphere to be unstable enough for convection. In a moist atmosphere, this lapse rate is 6.5 °C/km (19 °F/mi), while in an atmosphere with less than 100% relative humidity, the required lapse rate is 9.8 °C/km (29 °F/mi).
To distinguish between the different states of fluid flow one must consider how the fluid reacts to a disturbance in the initial state.See Chandrasekhar (1961) "Hydrodynamic and Hydromagnetic stability" These disturbances will relate to the initial properties of the system, such as velocity, pressure, and density. James Clerk Maxwell expressed the qualitative concept of stable and unstable flow nicely when he said: > "when an infinitely small variation of the present state will alter only by > an infinitely small quantity the state at some future time, the condition of > the system, whether at rest or in motion, is said to be stable but when an > infinitely small variation in the present state may bring about a finite > difference in the state of the system in a finite time, the system is said > to be unstable." That means that for a stable flow, any infinitely small variation, which is considered a disturbance, will not have any noticeable effect on the initial state of the system and will eventually die down in time.
Ergoflavin was first isolated in pure form from Claviceps purpurea (ergot) in 1958. It was shown to be a 2,2’- biaryl linked dimer in 1963 and the structure confirmed that year by single-crystal X-ray analysis. During the following decade the structures of secalonic acids A, B, C, D and ergochrysin A were similarly firmly established, and although there was some early contention whether they were 2,2’-, 4,4’- or even 2,4’-linked it was confirmed that they too were all 2,2’- linked between the biphenyl residues. In all known secalonic acids, the methyl and methoxycarbonyl substituents are found to be trans to each other, and X-ray analysis of the crystal structure of secalonic acid A showed that the 2,2’-biaryl linkage was nonplanar and the angle between the two biphenyl planes was 36.5°. Isomerisation of 2,2’-, 2,4’-, and 4,4’-linked Secalonic acid A The tetrahydroxanthone-containing secalonic acids have been demonstrated to be unstable under basic conditions, and they can easily undergo isomerizations arising from ether linkage replacement. The 2-2’linked secalonic acid A isomerizes in DMSO at room temperature to the 2-4’linked secalonic acid A and 4-4’linked secalonic acid A during 13hr, to reach an equilibrium of 3.2 : 2 : 1.
