Luminescence in a semiconductor results when an electron in the conduction band recombines with a hole in the valence band. The difference energy (band gap) of this transition can be emitted in form of a photon. The energy (color) of the photon, and the probability that a photon and not a phonon will be emitted, depends on the material, its purity, and the presence of defects. First, the electron has to be excited from the valence band into the conduction band.
|
|
In C99, a function defined `inline` will never, and a function defined `extern inline` will always, emit an externally visible function. Unlike in C++, there is no way to ask for an externally visible function shared among translation units to be emitted only if required. If `inline` declarations are mixed with `extern inline` declarations or with unqualified declarations (ie., without `inline` qualifier or storage class), the translation unit must contain a definition (no matter whether unqualified, `inline`, or `extern inline`) and an externally visible function will be emitted for it.

This allows only light in a very narrow frequency range to resonate in the cavity and be emitted as laser emission. The wide tunability range, high output power, and pulsed or CW operation make the dye laser particularly useful in many physical & chemical studies.
|
|
Or the electron can even break free from its associated atom's shell; this is ionization to form a positive ion. When an electron loses energy (thereby causing a photon to be emitted), then it can move to an inner shell which is not fully occupied.
|
|
This process of accretion is one of the most efficient energy- producing processes known; up to 40% of the rest mass of the accreted material can be emitted as radiation. (In nuclear fusion only about 0.7% of the rest mass will be emitted as energy.) In many cases, accretion disks are accompanied by relativistic jets that are emitted along the poles, which carry away much of the energy. The mechanism for the creation of these jets is currently not well understood, in part due to insufficient data. As such, many of the universe's more energetic phenomena have been attributed to the accretion of matter on black holes.

|
|
There are concerns, originating in the USA that drilling could lead to pollution from hydrocarbon based chemicals. Regulations in the UK call for total fluid and gas security meaning that in routine operations, no unburnt gases would be emitted. Venting of unburnt gas is only permitted for safety reasons or in an emergency.

Data on the rates at which CO2 is being released into the atmosphere is not robust currently; however, research is being conducted to gather a better information to analyze trends. Loss of underground biomass (roots and rhizomes) will allow for CO2 to be emitted changing these habitats into sources rather than carbon sinks.

Compounds including benzodiazepines, which are positive modulators of GABA receptors, will decrease the production of ultrasonic vocalizations which are emitted in response to social isolation. During emission of 22-kHz calls, juveniles and adults are often exhibiting freezing behaviour and experiencing an increase in heart rate and blood pressure. Since 22-kHz calls are emitted in response to unpleasant situations and noxious stimuli, it has been thought that these calls serve two functions: reflecting anxiety, and communication. With respect to communication, these calls could be emitted as threat signalling to conspecifics or individuals of other species to decrease the probability of an aggressive encounter, or they could be emitted as alarm calling to warn other individuals in the population of imminent danger.

Internal conversion is a radioactive decay process wherein an excited nucleus interacts electromagnetically with one of the orbital electrons of the atom. This causes the electron to be emitted (ejected) from the atom.M.E.

EUV light can also be emitted by free electrons orbiting a synchrotron. Continuously tunable narrowband EUV light can be generated by four wave mixing in gas cells of krypton and hydrogen to wavelengths as low as 110 nm. In windowless gas chambers fixed four wave mixing has been seen as low as 75 nm.

A hologram emitter created multiple images to make the armor harder to target. In addition to the sonic emitter, a voice distorter helped protect Stark's identity and could also be used to duplicate sounds. The armor could travel underground. Freon could be emitted and a built-in fire extinguisher handled internal and external fire.
|
|
The electrons from the highest occupied states will have the highest kinetic energy. In metals, those electrons will be emitted from the Fermi level. When the photoelectron is emitted into a solid rather than into a vacuum, the term internal photoemission is often used, and emission into a vacuum is distinguished as external photoemission.

Alternatively, the protons may be emitted separately but simultaneously—so-called "democratic decay". The experiment was not sensitive enough to establish which of these two processes was taking place. More evidence of was found in 2008 at the Istituto Nazionale di Fisica Nucleare, in Italy. A beam of ions was directed at a target of beryllium foil.

Then they would cut the pipe's head and attach the instrument's reed to this place. On the surface, the area of reed is a bit cut off. Only from this air way the air should be emitted, that is why the blowing part (neck) is entirely closed. Then they cut 8 oval front keys along the instrument's reed.

Neutral atoms or condensed matter cannot emit EUV radiation. Ionization must take place first. EUV light can only be emitted by electrons which are bound to multicharged positive ions; for example, to remove an electron from a +3 charged carbon ion (three electrons already removed) requires about 65 eV. Such electrons are more tightly bound than typical valence electrons.
|
|
These well-developed perturbation methods were adopted and adapted to solve new problems arising during the development of quantum mechanics in 20th century atomic and subatomic physics. Paul Dirac developed quantum perturbation theory in 1927 to evaluate when a particle would be emitted in radioactive elements. This was later named Fermi's golden rule. See equations (24) and (32).

On 2 January 1980, the use of separate stamps for the Azores (and Madeira) were revived. The modern stamps are inscribed both "PORTUGAL" and "AÇORES". Personalized and regional stamps began to be emitted from 2008 by the Portuguese postal service. These stamps have no special purpose beyond the expression of local pride; all are sold and valid in Portugal.

This phenomenon could only be explained via photons. Einstein's "light quanta" would not be called photons until 1925, but even in 1905 they represented the quintessential example of wave-particle duality. Electromagnetic radiation propagates following linear wave equations, but can only be emitted or absorbed as discrete elements, thus acting as a wave and a particle simultaneously.

Japanese coins of the 17th to 19th centuries Coinage in Japan initially consisted of Chinese coins that arrived in Japan through trade. It is not clear when the influx of Chinese coins began. In the late 7th century CE, domestically minted coins commenced. Such domestically minted coins, modelled on the Tang Dynasty precedent, continued to be emitted until 958.

|
This often activates the nucleus, putting it into an excited, unstable, short-lived energy state which causes it to quickly emit some kind of radiation to bring it back down to a stable or ground state. Alpha, beta, gamma, and protons may be emitted. Particles scattered in this type of nuclear reaction may cause the nucleus to recoil in the other direction.
|
|
31 in Also, the photon does not obey the Pauli exclusion principle, but instead obeys Bose–Einstein statistics. Photons are emitted in many natural processes. For example, when a charge is accelerated it emits synchrotron radiation. During a molecular, atomic or nuclear transition to a lower energy level, photons of various energy will be emitted, ranging from radio waves to gamma rays.

A solar eclipse. Coronium, also called newtonium, was the name of a suggested chemical element, hypothesised in the 19th century. The name, inspired by the solar corona, was given by Gruenwald in 1887. A new atomic thin green line in the solar corona was then considered to be emitted by a new element unlike anything else seen under laboratory conditions.

General γ-γ-cascade with life-time \tau_N of the intermediate state. The first \gamma- quantum (\gamma_1, k_1) will be emitted isotopically. Detecting this quantum in a detector selects a subset with an orientation of the many possible directions that has a given. The second \gamma-quantum (\gamma_2, k_2) has an anisotropic emission and shows the effect of the angle correlation.

Since Sercos III telegrams continue to be emitted by transmit PMAs on unconnected ports, and receive PMAs on unconnected ports continue to monitor for incoming data, when a Sercos III port recognizes that a ring has by physically re-closed, it will re-activate the counter-rotating telegrams to functionally close the rings again. This operation is also bump-less.

Additive color mixing: Three overlapping light bulbs in a vacuum, adding together to create white. Subtractive color mixing: Three splotches of paint on white paper, subtracting together to turn the paper black. RGB uses additive color mixing, because it describes what kind of light needs to be emitted to produce a given color. RGB stores individual values for red, green and blue.

When considering light in the context of contact electrification, the light energy is changed directly into electrical energy, allowing creation of solar cells. Later it was found that the same process can be reversed, and if a current is forced backwards across the contact region between the semiconductors, sometimes light will be emitted, allowing creation of the light-emitting diode (LED).
|
|
It is therefore an E2 transition. The case of the 1.17 MeV transition is a bit more complex: going from J = 4 to J = 2, all values of angular momentum from 2 to 6 could be emitted. But in practice, the smallest values are most likely, so it is also a quadrupole transition, and it is E2 since there is no parity change.
|

A fiber laser is usually generated first from a laser diode. The laser diode then couples the light into a fiber where it will be confined. Different wavelengths can be achieved with the use of doped fiber. The pump light from the laser diode will excite a state in the doped fiber which can then drop in energy causing a specific wavelength to be emitted.

Flight formation aerobatics are flown by teams of up to sixteen aircraft, although most teams fly between four and ten aircraft.The record is a 22-aircraft formation in 1958. Some are state funded to reflect pride in the armed forces while others are commercially sponsored. Coloured smoke trails may be emitted to emphasise the patterns flown and/or the colours of a national flag.

In this alternating timed automaton, two branches are started. A branch restarts the clock x, and ensures that each time in the future when a letter is emitted, the clock x is distinct from 1. This ensure that between this letter and the next ones, the time elapsed is not one. The second branch only waits for other letters to be emitted and do the same checking.

The Fisker Karma has an automatic warning sound-generator. The 2011 Chevrolet Volt includes a manually activated warning sound. Fisker Automotive developed a sound-generator that was incorporated in its Fisker Karma luxury plug-in hybrid electric vehicle, released in 2011. According to the car manufacturer, the sound is designed to both alert pedestrians and enhance the driver experience, and the warning noise will be emitted automatically.

No such designation exists for the amount of reflector coverage the lamp has. Reflector lamps are used when light is only desired to be emitted in a single direction, or when an application requires the maximum amount of light. For example, these lamps can be used in tanning beds or in backlighting electronic displays. An internal reflector is more efficient than standard external reflectors.
|
|
In an "indirect" gap, a photon cannot be emitted because the electron must pass through an intermediate state and transfer momentum to the crystal lattice. Examples of direct bandgap materials include amorphous silicon and some III-V materials such as InAs, GaAs. Indirect bandgap materials include crystalline silicon and Ge. Some III-V materials are indirect bandgap as well, for example AlSb. Energy vs.

60Co Decay, with spins and parities shownAlpha- beta- and gamma rays can only be emitted if the conservation laws (energy, angular momentum, parity) are obeyed. This leads to so-called selection rules. Applications for gamma decay can be found in Multipolarity of gamma radiation. To discuss such a rule in a particular case, it is necessary to know angular momentum and parity for every state.
|
|
In quantum mechanics, angular momentum is quantized. The various multipole fields have particular values of angular momentum: E\ell radiation carries an angular momentum \ell in units of \hbar; likewise, M\ell radiation carries an angular momentum \ell in units of \hbar. The conservation of angular momentum leads to selection rules, i.e., rules defining which multipoles may or may not be emitted in particular transitions.

Principle: Photoacoustic tomography (PAT) works on the natural phenomenon of tissues to thermalelastically expand when stimulated with externally applied electromagnetic waves, such as short laser pulses. This causes ultrasound waves to be emitted from these tissues, which can then be captured by an ultrasound transducer. The thermoelastic expansion and the resulting ultrasound wave is dependent on the wavelength of light used. PAT allows for complete non-invasiveness when imaging the animal.

This would require more than one neutron to be emitted per fission on average in order to keep the chain reaction going. By March 1939, they established that about two were being emitted per fission on average. The delay between an atom absorbing a neutron and fission occurring would be the key to controlling a chain reaction. At this point Zinn began working for Fermi, constructing experimental uranium lattices.

Such behavior is said to be emitted because it does not force the behavior to occur since stimulus control is a direct result of historical reinforcement contingencies, as opposed to reflexive behavior that is said to be elicited through respondent conditioning. Some theorists believe that all behavior is under some form of stimulus control. For example, in the analysis of B. F. Skinner,Skinner, Burrhus Frederick (1957). Verbal Behavior.

The merger is accompanied by the emission of gravitational waves, which can be emitted anisotropically, imparting linear momentum to the merger remnant - in effect, "kicking" the black hole out of the galaxy. This discovery is important because it indirectly proves that black holes merge and that the mergers can be accompanied by large kicks. This process had been postulated by theory, but never before confirmed via direct observation.
|
|
Skinner notes his categories of verbal behavior: mand, textual, intraverbal, tact, audience relations, and notes how behavior might be classified. He notes that form alone is not sufficient (he uses the example of "fire!" having multiple possible relationships depending on the circumstances). Classification depends on knowing the circumstances under which the behavior is emitted. Skinner then notes that the "same response" may be emitted under different operant conditions.

Hawking had initially opposed Bekenstein's idea on the grounds that a black hole could not radiate energy and therefore could not have entropy.Overbye, Dennis, Jacob Bekenstein, Physicist, dies at 68; revolutionized the study of black holes, New York Times, August 22, 2015, p.B7 However, in 1974, Hawking performed a lengthy calculation that convinced him that particles can indeed be emitted from black holes. Today this is known as Hawking radiation.

The construction of the two power stations has provoked a huge controversy in Norway, due to the large amounts of carbon dioxide that will be emitted. The Kårstø plant will emit 1.2 million tonnes of carbon dioxide, or about 2.5% of the total emissions of Norway. Prior to the opening of the Kårstø power station on November 2, 2007 Norway's sole domestic production of grid electricity was provided through renewable energy.

A common technique for many radar systems (usually also found in SAR systems) is to "chirp" the signal. In a "chirped" radar, the pulse is allowed to be much longer. A longer pulse allows more energy to be emitted, and hence received, but usually hinders range resolution. But in a chirped radar, this longer pulse also has a frequency shift during the pulse (hence the chirp or frequency shift).

As the atomic number Z increases, so too does the number of potential Auger transitions. Fortunately, the strongest electron-electron interactions are between levels that are close together, giving rise to characteristic peaks in an Auger spectrum. KLL and LMM peaks are some of the most commonly identified transitions during surface analysis. Finally, valence band electrons can also fill core holes or be emitted during KVV-type transitions.

|
The "photoelectrons" emitted as a result of the photoelectric effect have a certain kinetic energy, which can be measured. This kinetic energy (for each photoelectron) is independent of the intensity of the light, but depends linearly on the frequency; and if the frequency is too low (corresponding to a photon energy that is less than the work function of the material), no photoelectrons are emitted at all, unless a plurality of photons, whose energetic sum is greater than the energy of the photoelectrons, acts virtually simultaneously (multiphoton effect). Assuming the frequency is high enough to cause the photoelectric effect, a rise in intensity of the light source causes more photoelectrons to be emitted with the same kinetic energy, rather than the same number of photoelectrons to be emitted with higher kinetic energy. Einstein's explanation for these observations was that light itself is quantized; that the energy of light is not transferred continuously as in a classical wave, but only in small "packets" or quanta.

A Notice of Hearing is a prepared legal document that invokes all parties to hear a motion and may be emitted by any party. Most notably the notice contains a time and date for the court clerk to amend schedule for and what motion will be attempted. Permission to schedule is not required since making motions are protected right. This kind of motion comes after the commencement of action and summons and until final judgment.

Instead of resulting in orderly, coherent phonons, laser structures that can produce terahertz sound tend to emit phonons randomly. Researchers have overcome the problem of terahertz frequencies by following various approaches. Scientists in Caltech have overcome this problem by assembling a pair of microscopic cavities that only permit specific frequencies of phonons to be emitted. This system can be also tuned to emit phonons of different frequencies by changing the relative separation of the microcavities.

Detecting zero kinetic energy or threshold electrons in threshold photoelectron photoion coincidence spectroscopy, TPEPICO, has two major advantages. Firstly, no kinetic energy electrons are produced in energy ranges with poor Franck–Condon factors in the photoelectron spectrum, but threshold electrons can still be emitted via other ionization mechanisms. Second, threshold electrons are stationary and can be detected with higher collection efficiencies, thereby increasing signal levels. Threshold electron detection was first based line-of-sight, i.e.

Further research on electrical properties is needed to explicate such conductivity in ta-C in order to determine its practical value. However, a different electrical property of emissivity has been shown to occur at unique levels for ta-C. Such high values allow for electrons to be emitted from ta-C coated electrodes into vacuum or into other solids with application of modest levels of applied voltage. This has supported important advances in medical technology.

Finally, one can hold the bowl of a single spoon in the left hand and hit it with another spoon. In this style, different sounds can be emitted by holding the bowl more or less tightly. These wooden spoons are commonly used in performances of Russian folk music and sometimes even in Russian orchestras. A video of a choir performing a Russian folk song with spoon and balalaika accompaniment can be found below.

Thomson enclosed a metal plate (a cathode) in a vacuum tube, and exposed it to high- frequency radiation. It was thought that the oscillating electromagnetic fields caused the atoms' field to resonate and, after reaching a certain amplitude, caused a subatomic corpuscles to be emitted, and current to be detected. The amount of this current varied with the intensity and color of the radiation. Larger radiation intensity or frequency would produce more current.

In practice most actual experiments have used light, assumed to be emitted in the form of particle-like photons (produced by atomic cascade or spontaneous parametric down conversion), rather than the atoms that Bell originally had in mind. The property of interest is, in the best known experiments, the polarisation direction, though other properties can be used. Such experiments fall into two classes, depending on whether the analysers used have one or two output channels.

|
Relativistically moving objects are beamed due to a variety of physical effects. Light aberration causes most of the photons to be emitted along the object's direction of motion. The Doppler effect changes the energy of the photons by red- or blue-shifting them. Finally, time intervals as measured by clocks moving alongside the emitting object are different from those measured by an observer on Earth due to time dilation and photon arrival time effects.

However, the port 3 is connected to a matched load. All the incoming signal is then absorbed and no signal can be emitted from port 3.Most common types of ferrite-based isolators are classified into four categories: terminated circulators, Faraday rotation isolators, field-displacement isolators, and resonance isolators. In all these kinds of device, the observed non- reciprocity arises from the wave-material interaction which depends on the direction of propagation.

Cofiring relates to the combustion of two different types of materials. The process is primarily used to decrease CO2 emissions despite the resulting lower energy efficiency and higher variable cost. The combination of materials usually contains a high carbon emitting substance such as coal and a lesser CO2 emitting material such as biomass. Even though CO2 will still be emitted through the combustion of biomass, the net carbon emitted is nearly negligible.

The dispersal of spores is different from most "typical" mushrooms that spread their spores through the air. Stinkhorns instead produce a sticky spore mass on their tip which has a sharp, sickly-sweet odor of carrion to attract flies and other insects. Odorous chemicals in the gleba include methanethiol, hydrogen sulfide, linalool, trans-ocimene, phenylacetaldehyde, dimethyl sulfide, and dimethyl trisulfide. The latter compound has been found to be emitted from fungating cancerous wounds.

The user navigates through the house into different rooms, each corresponding with a set of variables which affect the amount of greenhouse gases which will be emitted on account of the user. In the bedroom, the user inputs the lighting settings include the number and kinds of lightbulbs and the heating and cooling settings (such as the temperatures and how many days each is used). In the living room, home appliance settings (e.g. TV) are adjusted.

After the IC electron has been emitted, the atom is left with a vacancy in one of its electron shells, usually an inner one. This hole will be filled with an electron from one of the higher shells, which causes another outer electron to fill its place in turn, causing a cascade. Consequently, one or more characteristic X-rays or Auger electrons will be emitted as the remaining electrons in the atom cascade down to fill the vacancies.

Bacher was able to report that the number of neutrons per fission of plutonium-239 was 2.64 ± 0.2, about 1.2 times as much as uranium-235. Titterton and Boyce McDaniel of Wilson's P-1 (Cyclotron) Group attempted to measure the time it took for prompt neutrons to be emitted from a uranium-235 nucleus when it fissions. They calculated that most were emitted in less than 1 nanosecond. Subsequent experiments demonstrated that fission took less than a nanosecond too.

Carbon rift is a theory attributing the input and output of carbon into the environment to human capitalistic systems. This is a derivative of Karl Marx's concept of metabolic rift. In practical terms, increased commodity production demands that greater levels of carbon dioxide (or CO2) be emitted into the biosphere via fossil fuel consumption. Carbon rift theory states that this ultimately disrupts the natural carbon cycle and that this "rift" has adverse effects on nearly every aspect of life.

That decision ultimately led to his development of special relativity as a theory founded on two postulates of which he could be sure. Expressed in contemporary physics vocabulary, his postulates were as follows: :1. The laws of physics take the same form in all inertial frames. :2. In any given inertial frame, the velocity of light c is the same whether the light be emitted by a body at rest or by a body in uniform motion.

But due to the surrounding environment adding energy, the electrons will be found in a range of energies at any given instant. Electrons that are not in the lowest possible energy state are known as "excited", as are the atoms that contain them. Stimulated emission occurs when an excited electron can drop by the same amount of energy as a passing photon. This causes a second photon to be emitted, closely matching the original's energy, momentum, and phase.

Neutrons are categorized according to their speed/energy. Neutron radiation consists of free neutrons. These neutrons may be emitted during either spontaneous or induced nuclear fission. Neutrons are rare radiation particles; they are produced in large numbers only where chain reaction fission or fusion reactions are active; this happens for about 10 microseconds in a thermonuclear explosion, or continuously inside an operating nuclear reactor; production of the neutrons stops almost immediately in the reactor when it goes non-critical.

The command line processors in DOS Plus, Multiuser DOS, REAL/32 and in all versions of DR-DOS support a number of optional environment variables to define escape sequences allowing to control text highlighting, reversion or colorization for display or print purposes in commands like TYPE. All mentioned command line processors support %$ON% and %$OFF%. If defined, these sequences will be emitted before and after filenames. A typical sequence for %$ON% would be \033[1m in conjunction with ANSI.

Because of that, in other directions less energy wil be emitted. The gain of an antenna, in a given direction, is usually referenced to an (hypothetical) isotropic antenna, which emits the radiation evenly strong in all directions. The antenna gain is the power in the strongest direction divided by the power that would be transmitted by an isotropic antenna emitting the same total power. In this case the antenna gain (Gi) is often specified in dBi, or decibels over isotropic.

|
This would signify the violation of parity symmetry because if the weak interaction were parity conserving, the decay emissions should be emitted with equal probability in all directions. As stated by Wu et al.: The reason for this is that the cobalt-60 nucleus carries spin, and spin does not change direction under parity (because angular momentum is an axial vector). Conversely, the direction that the decay products are emitted is changed under parity because momentum is a polar vector.

Ravindra Nath Sudan (also called Ravi Sudan; June 8, 1931 – January 22, 2009) was an Indian-American electrical engineer and physicist who specialized in plasma physics. He was known for independently discovering the whistler instability in 1963, an instability which causes audible low-frequency radio waves to be emitted in the magnetosphere in the form of whistler waves. He also pioneered the study of the generation and propagation of intense ion beams, and contributed to theories of plasma instabilities and plasma turbulence.

Light causes cumulative and irreversible damage to light-sensitive objects. The energy from light interacts with objects at the molecular level and can lead to both physical and chemical damage such as fading, darkening, yellowing, embrittlement, and stiffening. Ultraviolet radiation and Infrared radiation, in addition to visible light, can be emitted from light sources and can also be damaging to material culture. Cultural institutions are tasked with finding the balance between needing light for patrons and guests and exposure to the collection.

Operant behavior is said to be "emitted"; that is, initially it is not elicited by any particular stimulus. Thus one may ask why it happens in the first place. The answer to this question is like Darwin's answer to the question of the origin of a "new" bodily structure, namely, variation and selection. Similarly, the behavior of an individual varies from moment to moment, in such aspects as the specific motions involved, the amount of force applied, or the timing of the response.

Passive sonar has a wide variety of techniques for identifying the source of a detected sound. For example, U.S. vessels usually operate 60 Hz alternating current power systems. If transformers or generators are mounted without proper vibration insulation from the hull or become flooded, the 60 Hz sound from the windings can be emitted from the submarine or ship. This can help to identify its nationality, as all European submarines and nearly every other nation's submarine have 50 Hz power systems.

One of the fundamental predictions of General Theory of Relativity is that of gravitational waves — waves of distortion of spacetime itself - propagating at a finite speed of light. This replaces the Newtonian gravitations forces which was instantaneous. Such waves are expected to be emitted when, for example, two massive inspiralling stars tend to coalesce under their mutual gravitations attraction. Accurate calculation of this gravitational radiation — its waveform — has been one of the major research programmes of the theoretical physics group at the institute.

The process of converting radioactivity to light requires a liquid medium of scintillation combination consisting soluble organic scintillators and organic solvents. During the process of radioactive decay, a beta particle will be released. While this particle travels in the medium, the energy it possesses is dissipated as it collides with the surrounding molecules in the solvent, exciting them while doing so. The excited molecules will transfer the energy they now possess to the scintillator molecules, where the energy will be emitted as light.

So, as temperature increases, the glow color changes from red to yellow to white to blue. Even as the peak wavelength moves into the ultra-violet, enough radiation continues to be emitted in the blue wavelengths that the body will continue to appear blue. It will never become invisible—indeed, the radiation of visible light increases monotonically with temperature. The Stefan–Boltzmann law also says that the total radiant heat energy emitted from a surface is proportional to the fourth power of its absolute temperature.

In the case of SN 2011fe, the companion star must have been smaller than the Sun, if it existed. The Chandra X-ray Observatory revealed that the X-ray radiation of five elliptical galaxies and the bulge of the Andromeda Galaxy is 30–50 times fainter than expected. X-ray radiation should be emitted by the accretion discs of Type Ia supernova progenitors. The missing radiation indicates that few white dwarfs possess accretion discs, ruling out the common, accretion-based model of Ia supernovae.

Fluorescent lamps may produce flicker at the power supply frequency (50 or 60 Hz), which is noticeable by more people. This happens if a damaged or failed cathode results in slight rectification and uneven light output in positive and negative going AC cycles. Power frequency flicker can be emitted from the ends of the tubes, if each tube electrode produces a slightly different light output pattern on each half-cycle. Flicker at power frequency is more noticeable in the peripheral vision than it is when viewed directly.

|
The `time of flight' of the pulse is defined as the time taken for it to be emitted by an acoustic source, scattered by an object and received by the detector, which is usually coincident with the source. The time of flight can be used to determine the distance of the inhomogeneity from the source given knowledge of the speed through the medium. Based on the measurement, a value is assigned to the location investigated. The transducer (or object) is moved slightly and then insonified again.

Each outgoing ion generated by an electron allows a number of electrons to be emitted. This number is approximately equal to the square root of the ratio of the ion mass to the electron mass. It can be seen in the below chart what a typical I-V curve looks like for a hollow cathode in electron emission mode. Given a certain keeper geometry (the ring in the figure above that the electrons exit through), ion flow rate, and Vp, the I-V profile can be determined.

Ventilation Air Methane Thermal Oxidizers are used for the very low methane concentrations operate continuously. These systems can destroy 95-98+% methane (CH4) that would otherwise be emitted. Ventilation Air Methane Thermal Oxidizers can be designed with hot gas bypass systems, re-circulation heat exchangers that convert heat into energy, and oxygen monitoring to reduce any possible carbon monoxide and/or nitrous oxide production. Methane streams allow the VAMTOX to operate at reduced or zero fuel usage, which makes these systems ideal for mine shaft ventilation operations.

Thunderstorms can produce a brief pulse of gamma radiation called a terrestrial gamma-ray flash. These gamma rays are thought to be produced by high intensity static electric fields accelerating electrons, which then produce gamma rays by bremsstrahlung as they collide with and are slowed by atoms in the atmosphere. Gamma rays up to 100 MeV can be emitted by terrestrial thunderstorms, and were discovered by space-borne observatories. This raises the possibility of health risks to passengers and crew on aircraft flying in or near thunderclouds.

While nanomaterials can increase energy efficiency of fuel in several ways, a drawback of their use lies in the effect of nanoparticles on the environment. With cerium oxide nanoparticle additives in fuel, trace amounts of these toxic particles can be emitted within the exhaust. Cerium oxide additives in diesel fuel have been shown to cause lung inflammation and increased bronchial alveolar lavage fluid in rats. This is concerning, especially in areas with high road traffic, where these particles are likely to accumulate and cause adverse health effects.

Somewhat over a million tonnes of CO2 is emitted for every TWh of electricity generated in Turkey by coal-fired power stations. According to page xix of the February 2020 (final) version of the Afşin- Elbistan C environmental impact assessment (EIA) it is aimed to generate just over 12.5 TWh (gross) per year, so why the CO2 emissions are predicted to be so high is unclear. According to the calculation on page 319 of the EIA, 61,636,279.98 tCO2/year would be emitted; this has been rounded above.

Localized surface Plasmon Resonance (LSPR) characteristically occurs in quantum dots which contain a base metal like Cadmium or Lead. this interaction of nano-scale metals with light is characterized by surface-bound charge density oscillations of the free electrons in resonance with the driving electromagnetic field and produces a specific intensity of light. In Laymen terms, this means the valence electron of the metal oscillates up and down in resonance with the applied electromagnetic field from the natural light thus causing a.different color to be emitted.

So, too much pollution could be emitted and people not involved in the production pay the cost of the pollution instead of the firm that initially emitted the air pollution. Critics of market failure theory, like Ronald Coase, Harold Demsetz, and James M. Buchanan argue that government programs and policies also fall short of absolute perfection. In this view, market failures are often small, and government failures are sometimes large. It is therefore the case that imperfect markets are often better than imperfect governmental alternatives.

Arno Penzias and Robert Wilson announce the discovery of a weak radio signal coming from all parts of the sky. Scientists figure out that this must be emitted by an object at a temperature of -270 °C. Soon it is recognized as the remnant of the very hot radiation from the Big Bang that created the universe 13 billion years ago, see Cosmic microwave background. This radio signal is emitted by the electron in hydrogen flipping from pointing up or down and is approximated to happen once in a million years for every particle.

Performance standards or emission limits are types of regulations that set an objective or performance level for the regulatory target to meet. What makes these regulatory approaches unique is that they do not specify how the polluter must meet the standard. These regulations can include emission limits that specify the rate, amount, and kinds of pollutants that may be emitted from a given source over a specific period. The EPA's various effluent limitations for water pollution under the Clean Water Act are simply a few of the many environmental regulations that are nominally performance standards.

The molecules are driven strongly between distinguishable molecular states at each specific location, so that finally light can be emitted at only a small fraction of space, hence an increased resolution. As well in the 1990s another super resolution microscopy method based on wide field microscopy has been developed. Substantially improved size resolution of cellular nanostructures stained with a fluorescent marker was achieved by development of SPDM localization microscopy and the structured laser illumination (spatially modulated illumination, SMI). Combining the principle of SPDM with SMI resulted in the development of the Vertico SMI microscope.

A key enabling technology of LIGA is the synchrotron, capable of emitting high- power, highly collimated X-rays. This high collimation permits relatively large distances between the mask and the substrate without the penumbral blurring that occurs from other X-ray sources. In the electron storage ring or synchrotron, a magnetic field constrains electrons to follow a circular path and the radial acceleration of the electrons causes electromagnetic radiation to be emitted forward. The radiation is thus strongly collimated in the forward direction and can be assumed to be parallel for lithographic purposes.

Here, η is the electron gun assembly (EGA) efficiency (~0.97 in TSS-1), ρ is the perveance of the EGA (7.2 micropervs in TSS-1), ΔVtc is the voltage across the accelerating grid of the EGA, and It is the emitted current. The perveance defines the space charge limited current that can be emitted from a device.

88–90 Ringing artifacts are also present in square waves; see Gibbs phenomenon. Ringing is undesirable because it causes extra current to flow, thereby wasting energy and causing extra heating of the components; it can cause unwanted electromagnetic radiation to be emitted; it can delay arrival at a desired final state (increase settling time); and it may cause unwanted triggering of bistable elements in digital circuits. Ringy communications circuits may suffer falsing. Ringing can be due to signal reflection, in which case it may be minimized by impedance matching.

Diagram showing a possible internal structure of Ceres Two models for the composition of Europa suggest a large subsurface ocean of liquid water. Similar models have been proposed for other celestial bodies in the Solar System Models of Solar System objects indicate the presence of liquid water in their internal differentiation. Some models of the dwarf planet Ceres, largest object in the asteroid belt indicate the possibility of a wet interior layer. Water vapor detected to be emitted by the dwarf planet may be an indicator, through sublimation of surface ice.

Albert C. Geyser is known for creating the Cornell Tube in 1905, named after the college with which he was associated. The Cornell Tube was made of heavy lead glass through which no x-rays were thought to be emitted and was thought to eliminate the danger of burning in medical use of the x-ray. Geyser claimed that the lead filtration would eliminate all unsafe radiation. He was known for promoting x-ray to eliminate "excessive hair" to achieve "faultless skin" that would be white and hairless.

Spectrum of the X-rays emitted by an X-ray tube with a rhodium target, operated at 60 kV. The continuous curve is due to bremsstrahlung, and the spikes are characteristic K lines for rhodium. The Duane–Hunt law explains why the continuous curve goes to zero at 21 pm. The Duane–Hunt law, named after the American physicists William Duane and Franklin L. Hunt, gives the maximum frequency of X-rays that can be emitted by Bremsstrahlung in an X-ray tube by accelerating electrons through an excitation voltage V into a metal target.

Cavity dumpers usually use a high- reflective mirror on each end of the cavity, allowing the beam to receive full gain from the medium. At a specific interval, the beam is redirected, using a device such as a Pockels cell, an acousto-optic modulator, or a fast-rotating prism or mirror. This redirected beam bypasses the end mirror, allowing a very powerful pulse to be emitted. Cavity dumpers can be used for continuous-wave operation, but their most common use is with mode-locked lasers, to extract a very short pulse at its peak intensity.

Benzene, known to be emitted from gas flares in undocumented quantities, is well recognized as a cause for leukemia and other blood-related diseases. A study done by Climate Justice estimates that exposure to benzene would result in eight new cases of cancer yearly in Bayelsa State alone. Gas flares are often close to communities and regularly lack fencing or protection for villagers who risk working near their heat. Many communities claim that nearby flares cause acid rain which corrodes their homes and other structures, many of which have zinc-based roofing.

In the early years the DCP did have an assembler (Dacoma), an application program called DCPProgen written in B6500 ALGOL. Later the NDL (Network Definition Language) compiler generated the DCP code and NDF (network definition file). There was one ALGOL function for each kind of DCP instruction, and if you called that function then the corresponding DCP instruction bits would be emitted to the output. A DCP program was an ALGOL program comprising nothing but a long list of calls on these functions, one for each assembly language statement.

In August 2017, rumors circulated regarding a short gamma-ray burst designated GRB 170817A, of the type conjectured to be emitted in the collision of two neutron stars. On 16 October 2017, the LIGO and Virgo collaborations announced that they had detected a gravitational wave event, designated GW170817. The gravitational wave signal matched prediction for the merger of two neutron stars, two seconds before the gamma-ray burst. The gravitational wave signal, which had a duration of about 100 seconds, was the first gravitational wave detection of the merger of two neutron stars.

Taking the address of an `inline` function requires code for a non-inlined copy of that function to be emitted in any case. In C99, an `inline` or `extern inline` function must not access `static` global variables or define non-`const` `static` local variables. `const static` local variables may or may not be different objects in different translation units, depending on whether the function was inlined or whether a call was made. Only `static inline` definitions can reference identifiers with internal linkage without restrictions; those will be different objects in each translation unit.

The episode refers to inconsistencies in dating UNIT stories when the Doctor is unsure whether he worked for UNIT in the 1970s or 1980s. Raynor initially envisioned the poisonous gas would be emitted by factories, but changed it in later drafts to cars for several reasons: the episode would provide social commentary and the idea of an "evil satnav system" was "much more engageable" and "irresistible". Davies thought the concept was "so very Doctor Who". Because the series was produced out of order, the "ATMOS" subplot was seeded in the previous episode "Partners in Crime".

Even the hardest vacuum produced on earth is still too dense for CELs to be observed. For this reason, when CELs were first observed by William Huggins in the spectrum of the Cat's Eye Nebula, he did not know what they were, and attributed them to a hypothetical new element called nebulium. However, the lines he observed were later found to be emitted by extremely rarefied oxygen. CELs are very important in the study of gaseous nebulae, because they can be used to determine the density and temperature of the gas.

For fully ionized atoms (bare nuclei), it is possible in likewise manner for electrons to fail to escape the atom, and to be emitted from the nucleus into low-lying atomic bound states (orbitals). This cannot occur for neutral atoms with low-lying bound states which are already filled by electrons. Bound-state β decays were predicted by Daudel, Jean, and Lecoin in 1947, and the phenomenon in fully ionized atoms was first observed for 163Dy66+ in 1992 by Jung et al. of the Darmstadt Heavy-Ion Research group.

A core electron can be removed from its core-level upon absorption of electromagnetic radiation. This will either excite the electron to an empty valence shell or cause it to be emitted as a photoelectron due to the photoelectric effect. The resulting atom will have an empty space in the core electron shell, often referred to as a core-hole. It is in a metastable state and will decay within 10−15 s, releasing the excess energy via X-ray fluorescence (as a characteristic X-ray) or by the Auger effect.

To treat the food, it is exposed to a radioactive source, for a set period of time to achieve a desired dose. Radiation may be emitted by a radioactive substance, or by X-ray and electron beam accelerators. Special precautions are taken to ensure the food stuffs never come in contact with the radioactive substances and that the personnel and the environment are protected from exposure radiation. Irradiation treatments are typically classified by dose (high, medium, and low), but are sometimes classified by the effects of the treatment (radappertization, radicidation and radurization).

The detection and timing of the gamma ray pulsations was used to determine the spin period of the pulsar to be 2.5 milliseconds. The presence of the companion to the pulsar causes very slight variations in the time at which these pulses appear to be emitted, meaning precise timing allows the minimum mass of the companion to be determined using Kepler's third law. The minimum mass found with this method is 8.2 x 10−3 M_\odot, or roughly 8 times the mass of Jupiter. Optical spectroscopy of this companion reveal that it is composed primarily of helium, with no hydrogen detected.

The term operant conditioning was introduced by B. F. Skinner to indicate that in his experimental paradigm the organism is free to operate on the environment. In this paradigm the experimenter cannot trigger the desirable response; the experimenter waits for the response to occur (to be emitted by the organism) and then a potential reinforcer is delivered. In the classical conditioning paradigm the experimenter triggers (elicits) the desirable response by presenting a reflex eliciting stimulus, the Unconditional Stimulus (UCS), which he pairs (precedes) with a neutral stimulus, the Conditional Stimulus (CS). Reinforcement is a basic term in operant conditioning.

A phonon laser device Sound amplification by stimulated emission of radiation (SASER) refers to a device that emits acoustic radiation. It focuses sound waves in a way that they can serve as accurate and high-speed carriers of information in many kinds of applications—similar to uses of laser light. Acoustic radiation (sound waves) can be emitted by using the process of sound amplification based on stimulated emission of phonons. Sound (or lattice vibration) can be described by a phonon just as light can be considered as photons, and therefore one can state that SASER is the acoustic analogue of the laser.

Cryogenic Optical Localization in Three Dimensions (COLD) allows to determine the four biotin binding sites in the protein streptavidin. Cryogenic Optical Localization in 3D (COLD) is a method that allows localizing multiple fluorescent sites within a single small- to medium-sized biomolecule with Angstrom-scale resolution. The localization precision in this approach is enhanced because the slower photochemistry at low temperatures leads to a higher number of photons that can be emitted from each fluorophore before photobleaching. As a result, cryogenic stochastic localization microscopy achieves the sub-molecular resolution required to resolve the 3D positions of several fluorophores attached to a small protein.

In NDP, a thermal or cold neutron beam passes through a material and interacts with isotopes that emit monoenergetic charged particles upon neutron absorption; either a proton or an alpha, and a recoil nucleus. Since the charged particles are equally likely to be emitted in any direction, reaction kinematics are straightforward. Because low-energy neutrons are used, there is no significant momentum transfer from the neutron beam to the substrate, and the analysis is practically non-destructive. As charged particles move towards the surface, they are rapidly slowed down, primarily by interacting with the electrons of the substrate.

The best theoretical explanation of the experimental results was the Rayleigh–Jeans law, which agrees with experimental results well at large wavelengths (or, equivalently, low frequencies), but strongly disagrees at short wavelengths (or high frequencies). In fact, at short wavelengths, classical physics predicted that energy will be emitted by a hot body at an infinite rate. This result, which is clearly wrong, is known as the ultraviolet catastrophe. However, classical physics led to the Rayleigh–Jeans law, which, as shown in the figure, agrees with experimental results well at low frequencies, but strongly disagrees at high frequencies.

When this exciton recombines (i.e. the electron resumes its ground state), the exciton's energy can be emitted as light. This is called fluorescence. In a simplified model, the energy of the emitted photon can be understood as the sum of the band gap energy between the highest occupied level and the lowest unoccupied energy level, the confinement energies of the hole and the excited electron, and the bound energy of the exciton (the electron-hole pair): the figure is a simplified representation showing the excited electron and the hole in an exciton entity and the corresponding energy levels.

On 8 June 2008, following the Second Reading of the Bill, only five members of the House of Commons voted against. The five were Christopher Chope, Philip Davies, Peter Lilley, Andrew Tyrie, and Ann Widdecombe.Charles Moore, "To win the battle for the consumer, Cameron must cut taxes soon", The Daily Telegraph, 28 September 2013. During the debate on the Third Reading on 28 October, the government rejected an opposition amendment to allow the Secretary of State to set the maximum level of carbon dioxide that may be emitted per unit of output by any generating station.

An obvious but often overlooked factor when analyzing response distributions is that responses are not instantaneous, but take some amount of time to emit (Killeen, 1994). These ceilings on response rate are often accounted for by competition from other responses, but less often for the fact that responses cannot always be emitted at the same rate at which they are elicited (Killeen & Sitomer, 2003). This limiting factor must be taken into account in order to correctly characterize what responding could be theoretically, and what it will be empirically. An organism may receive impulses to respond at a certain rate.

The boundary of this region is called the event horizon and has an effective radius called the Schwarzschild radius, which is about for Cygnus X-1. Anything (including matter and photons) that passes through this boundary is unable to escape. Evidence of just such an event horizon may have been detected in 1992 using ultraviolet (UV) observations with the High Speed Photometer on the Hubble Space Telescope. As self-luminous clumps of matter spiral into a black hole, their radiation will be emitted in a series of pulses that are subject to gravitational redshift as the material approaches the horizon.

Additional kinetic energy is required to move an electron out of the conduction band and into the vacuum level. This is known as the electron affinity of the photocathode and is another barrier to photoemission other than the forbidden band, explained by the band gap model. Some materials such as gallium arsenide have an effective electron affinity that is below the level of the conduction band. In these materials, electrons that move to the conduction band all have sufficient energy to be emitted from the material, so the film that absorbs photons can be quite thick.

The call is a distinctive rippling whistle, per,r,r,rit and the typical Plectrophenax warble hudidi feet feet feew hudidi. Snow buntings use vocalizations to communicate among each other and males will have a song to attract the female. The communication calls are done by both the male and the female and they tend to be emitted in flight or in the ground, while the males will often emit the song from a perching position or in a flight display. The males will start singing as soon as they will reach the breeding grounds, and will stop once they find a mate.

In 2001–2002 the UK government performed a study on 18 untrained subjects. The experimenters recorded the Electric field and Magnetic field around each viewer to see if the cerebral activity of successful viewings caused higher-than-usual fields to be emitted from the brain. However, the experimenters did not find any evidence that the viewers had accessed the targets in the data collection phase, the project was abandoned, and the data was never analyzed since no RV activity had happened. Some "narrow-band" Electric fields were detected during the viewings, but they were attributed to external causes.

Cheduba Island was a stop on the coastal trade route from Bengal by which Indian civilization migrated to Myanmar. Historical records show that an earthquake of a magnitude of 8.5 to 9.0 hit off the western coast of Myanmar in April 1762, and reports speculated that a tsunami could kill more than one million people in Myanmar and Bangladesh. In 1881, a 7.9 magnitude earthquake in the Bay of Bengal caused "broad massive flames of fire" to be emitted on the island. In the 1780s, after the Burmese conquest of the area, Cheduba became a province of Arakan.

Reducing the output of New Zealand firms, it is argued, will result in increased production in another nation, and perhaps a net increase in global emissions. Economist Geoff Bertram compared the price incentives of the 2008 NZ ETS with a carbon or greenhouse gas tax for Kyoto commitment period 1, 2008 to 2012. A tax of $NZ30 per tonne, on the 386 million tonnes of emitted greenhouse gases likely to be emitted from 2008 to 2012, would give a price signal (or government revenue) of $NZ11.6 billion. The exemptions and subsidies in Labour's ETS would have reduced that to about $NZ1 billion.

TRIUMF utilizes a technique called μSR, a powerful probe into materials like semiconductors, magnets and superconductors. Beams of positive muons are created with their spins lined up in the same direction. When these beams are shot into a material, the muons' spins precess (wobble like a top) around the local magnetic fields in the material. The unstable muons soon decay into positrons; since these antielectrons tend to be emitted in the direction of the muons' spin, μSR scientists can examine how the internal magnetic fields of different materials have affected the muons' spins by observing the directions in which the positrons are emitted.

When a nucleus in a solid emits or absorbs a gamma ray, some energy can still be lost as recoil energy, but in this case it always occurs in discrete packets called phonons (quantized vibrations of the crystal lattice). Any whole number of phonons can be emitted, including zero, which is known as a "recoil-free" event. In this case conservation of momentum is satisfied by the momentum of the crystal as a whole, so practically no energy is lost.International Board on the Applications of the Mössbauer Effect (IBAME) and Mössbauer Effect Data Center (MEDC), Mössbauer Effect website Accessed June 3, 2010.

Some jet trainers, such as the Aermacchi MB-326, Casa C-101, Folland Gnat, Fouga Magister and British Aerospace Hawk, are used by national formation aerobatic teams. Early jet aerobatic teams tended to use combat types such as the Hawker Hunter, English Electric Lightning, and North American F-100 Super Sabre. As air forces' combat fleets were scaled-down, it made sense for most national display teams to change to lighter training types. A few modifications may be needed to enable coloured smoke to be emitted during displays, but essentially these airframes can still perform their pilot training function.

It was during this time that KB-11 found that they could use lithium–deuterium as a thermonuclear fuel to replace the deuterium–tritium fuel that was decided upon after publication of the Teller–Ulam tests. Several factors had to be overcome by Design Bureau 11 in implementing the idea of atomic compression. The main problems dealt with the massive amounts of radiation that would be emitted from the initial atomic bomb implosion. The calculated yields were large enough that there was much concern whether or not a structure could be engineered to house and hold the energy emission.

In support of all this, Langer cites ethnographic reports of tribal songs consisting entirely of "rhythmic nonsense syllables". She concedes that an English equivalent such as "hey-nonny-nonny", although perhaps suggestive of certain feelings or ideas, is neither noun, verb, adjective, nor any other syntactical part of speech. So long as articulate sound served only in the capacity of "hey nonny-nonny", "hallelujah" or "alack-a-day", it cannot yet have been speech. For that to arise, according to Langer, it was necessary for such sequences to be emitted increasingly out of context — outside the total situation that gave rise to them.

According to the standard calculations these are harmless because they would quickly decay by Hawking radiation. Hawking radiation is a thermal radiation predicted to be emitted by black holes due to quantum effects. Because Hawking radiation allows black holes to lose mass, black holes that lose more matter than they gain through other means are expected to dissipate, shrink, and ultimately vanish. Smaller micro black holes (MBHs), which could be produced at the LHC, are currently predicted by theory to be larger net emitters of radiation than larger black holes, and to shrink and dissipate instantly.

The value is defined as the total energy released in a given nuclear decay. In beta decay, is therefore also the sum of the kinetic energies of the emitted beta particle, neutrino, and recoiling nucleus. (Because of the large mass of the nucleus compared to that of the beta particle and neutrino, the kinetic energy of the recoiling nucleus can generally be neglected.) Beta particles can therefore be emitted with any kinetic energy ranging from 0 to . A typical is around 1 MeV, but can range from a few keV to a few tens of MeV.

The compositor in turn sends information back to the client by causing the object to emit events (probably with arguments too). These events can be emitted by the compositor as a response to a certain request, or asynchronously, subject to the occurrence of internal events (such as one from an input device) or state changes. The error conditions are also signaled as events by the compositor. For a client to be able to make a request to an object, it first needs to tell the server the ID number it will use to identify that object.

Thermal radiation is characterized by a particular spectrum of many wavelengths that are associated with emission from an object, due to the vibration of its molecules at a given temperature. Thermal radiation can be emitted from objects at any wavelength, and at very high temperatures such radiation is associated with spectra far above the infrared, extending into visible, ultraviolet, and even X-ray regions (e.g. the solar corona). Thus, the popular association of infrared radiation with thermal radiation is only a coincidence based on typical (comparatively low) temperatures often found near the surface of planet Earth.

In electron spectroscopy, depending on the technique, irradiating the sample with high-energy particles such as X-ray photons, electron beam electrons, or ultraviolet radiation photons, causes Auger electrons and photoelectrons to be emitted. Figure 1 illustrates this on the basis of a single particle in which, for example, the incoming X-ray photon from a particular energy range (E=hν) transfers its energy to an electron in the inner shell of an atom. Photon absorption causes electron emission leaves a hole in the atomic shell (see figure 1 (a)). The hole can be filled in two ways, forming different characteristic rays that are specific to each element.

The subject of mouthpiece pressure is closely related to the issue of embouchure collapse/embouchure overuse. Many brass instrumentalists argue that excessive mouthpiece pressure is a major cause of embouchure problems and can be a factor in causing embouchure collapse. However, the pressure of the mouthpiece is not static during playing: it increases the higher in the register a player plays and the louder volume level. Also, a little mouthpiece pressure is essential to provide a seal between the player's embouchure and the instrument; without this, all the air would escape before entering the instrument and no sound would be emitted (brass instruments are dependent on an airflow to produce sound).

In order to be used as a tracer, a compound must be emitted preferentially by some sources and not by others, giving the emission source a relatively unique chemical makeup. The compound must react slowly enough in the atmosphere that it is chemically conserved from the emission source to the receptor site where an ambient sample may be taken. Additionally, a tracer species should not be formed in the atmosphere and it should not volatilize during transport so that mass balance is maintained. Tracer compounds must then be of primary origins (not formed in the atmosphere), which are created through condensation and coagulation of mainly combustion and biological sources.

The basic structure of carbon fee and dividend is as follows: # A fee is levied on fuels at their point of origin into the economy, such as the well, mine, or port of entry. The fee is based upon the carbon content of a given fuel, with a commonly-proposed starting point being $10–$16 per ton of carbon that would be emitted once the fuel is burned. # The fee is progressively increased, providing a steady, predictable price signal and incentivizing early transition to low-carbon energy sources and products. # A border tax adjustment is levied on imports from nations that lack their own equivalent fee on carbon.

Neutrons may be emitted from nuclear fusion or nuclear fission, or from other nuclear reactions such as radioactive decay or particle interactions with cosmic rays or within particle accelerators. Large neutron sources are rare, and usually limited to large-sized devices such as nuclear reactors or particle accelerators, including the Spallation Neutron Source. Neutron radiation was discovered from observing an alpha particle colliding with a beryllium nucleus, which was transformed into a carbon nucleus while emitting a neutron, Be(α, n)C. The combination of an alpha particle emitter and an isotope with a large (α, n) nuclear reaction probability is still a common neutron source.

Class numbers were designated using Roman numerals (I–IV) in the US under the old system and Arabic numerals (1–4) in the EU. The revised system uses Arabic numerals (1–4) in all jurisdictions. The classification of a laser is based on the concept of accessible emission limits (AEL) that are defined for each laser class. This is usually a maximum power (in W) or energy (in J) that can be emitted in a specified wavelength range and exposure time that passes through a specified aperture stop at a specified distance. For infrared wavelengths above 4 μm, it is specified as a maximum power density (in W/m2).

In the summer of 1985, Robin Cannon and Charlotte Bullock established CCSCLA is response to the proposed construction of the Los Angeles City Energy Recovery (LANCER) municipal waste incinerator. The waste facility would burn million of tons of waste during its operation causing concern for citizens of the pollutants that would be emitted. Cannon and Bullock were concerned South Central Los Angeles was chosen for the incinerator's location because of the community's high unemployment rate, low average income, and high population of people of color. The LANCER was to be built in a vacant lot, near Jefferson High School and a public recreation center in a residential area of 16,000 people.

Muon capture is the capture of a negative muon by a proton, usually resulting in production of a neutron and a neutrino, and sometimes a gamma photon. Muon capture by heavy nuclei often leads to emission of particles; most often neutrons, but charged particles can be emitted as well. Ordinary muon capture (OMC) involves capture of a negative muon from the atomic orbital without emission of a gamma photon: : + -> μ + Radiative muon capture (RMC) is a radiative version of OMC, where a gamma photon is emitted: : + -> μ + + Theoretical motivation for the study of muon capture on the proton is its connection to the proton's induced pseudoscalar form factor gp.

Cosmic Hot Interstellar Plasma Spectrometer The primary objective of the science team, led by Principal Investigator Mark Hurwitz, was to study the million-degree gas in the local interstellar medium. CHIPSat was designed to capture the first spectra of the faint, extreme ultraviolet glow that is expected to be emitted by the hot interstellar gas within about 300 light-years of the Sun, a region often referred to as the Local Bubble. Surprisingly, these measurements produced a null result, with only very faint EUV emissions detected, despite theoretical expectations of much stronger emissions. It was the first U.S. mission to use TCP/IP for end-to-end satellite operations control.

Estimates vary on how many tons of greenhouse gases are emitted from thawed permafrost soils. One estimate suggests that 110–231 billion tons of CO2 equivalents (about half from carbon dioxide and the other half from methane) will be emitted by 2040, and 850–1400 billion tons by 2100. This corresponds to an average annual emission rate of 4–8 billion tons of CO2 equivalents in the period 2011–2040 and annually 10–16 billion tons of CO2 equivalents in the period 2011–2100 as a result of thawing permafrost. For comparison, the anthropogenic emission of all greenhouse gases in 2010 is approximately 48 billion tons of CO2 equivalents.

In particle physics, soft photons are photons having photon energies much smaller than the energies of the particles participating in a particular scattering process, and they are not energetic enough to be detected. Such photons can be emitted from (or absorbed by) the external (incoming and outgoing) lines of charged particles of the Feynman diagram for the process. Even though soft photons are not detected, the possibility of their emission must be taken into account in the calculation of the scattering amplitude., pages 177-184 and appendix A6 Taking the soft photons into account multiplies the rate of a given process by a factor which approaches zero.

However, because the researchers cannot definitively rule out the Cherenkov radiation effects as a probable cause of the LF experienced by astronauts, it seems likely that some LF may be the result of Cherenkov radiation effects in the eye itself, instead. The Cherenkov effect can cause Cherenkov light to be emitted in the vitreous body of the eye and thus allow the person to perceive the LF. Hence, it appears that the LF perceived by astronauts in space have different causes. Some may be the result of actual light stimulating the retina, while others may be the result of activity that occurs in neurons along the visual pathway, producing phosphenes.

If the concentration of ice nuclei is seeded such that the resulting cloud particle density is less than that for the natural case, the cloud particles should grow larger due to less water vapor competition and attain higher settling velocities. By seeding with aerosols, ice crystals could grow rapidly and deplete water vapor, suppress nucleation and any growth of ice crystals by homogeneous nucleation. The net effect would be a reduced optical thickness and a reduced cloud lifetime, allowing more infrared radiation to be emitted at the top of the atmosphere, as the ice particles sediment out. Less upper tropospheric water vapor and infrared radiation in the atmosphere would consequently cool the climate.

Additionally, absorption at any of the above wavelengths stimulates fluorescent emission of 694-nanometer-wavelength red light, which adds to its red color and perceived luster. After absorbing short-wavelength light, there is a short interval of time when the crystal lattice of ruby is in an excited state before fluorescence occurs. If 694-nanometer photons pass through the crystal during that time, they can stimulate more fluorescent photons to be emitted in-phase with them, thus strengthening the intensity of that red light. By arranging mirrors or other means to pass emitted light repeatedly through the crystal, a ruby laser in this way produces a very high intensity of coherent red light.

Bluetooth low energy devices can operate in an advertisement mode to notify nearby devices of their presence. In the simplest form, an iBeacon is a Bluetooth low energy device emitting advertisements following a strict format, that being an Apple-defined iBeacon prefix, followed by a variable UUID, and a major, minor pair. An example iBeacon advertisement frame could look like: fb0b57a2-8228-44 cd-913a-94a122ba1206 Major 1 Minor 2 where fb0b57a2-8228-44 cd-913a-94a122ba1206 is the UUID. Since iBeacon advertising is just an application of the general Bluetooth Low Energy advertisement, the above iBeacon can be emitted by issuing the following command on Linux to a supported Bluetooth 4 Low Energy device on a modern kernel.

If an electron in an atom is moving on an orbit with period , classically the electromagnetic radiation will repeat itself every orbital period. If the coupling to the electromagnetic field is weak, so that the orbit does not decay very much in one cycle, the radiation will be emitted in a pattern which repeats every period, so that the Fourier transform will have frequencies which are only multiples of . This is the classical radiation law: the frequencies emitted are integer multiples of . In quantum mechanics, this emission must be in quanta of light, of frequencies consisting of integer multiples of , so that classical mechanics is an approximate description at large quantum numbers.

Market failure occurs when an externality is present and a market will often either under-produce a product with a positive externalisation or overproduce a product that generates a negative externalisation. Air pollution is a negative externalisation that cannot be easily incorporated into markets as the world's air is not owned and then sold for use to polluters. So too much pollution could be emitted and people not involved in the production pay the cost of the pollution instead of the firm that initially emitted the air pollution. Critics of market failure theory such as Ronald Coase, Harold Demsetz and James M. Buchanan argue that government programs and policies also fall short of absolute perfection.

Bekenstein noted that this theorized outcome violated the quantum mechanical law of reversibility, which essentially holds that quantum information must not be lost in any process. This field of study is today known as black hole thermodynamics. Even if quantum information was not extinguished in the singularity of a classic black hole and it somehow still existed, quantum data would be unable to climb up against infinite gravitational intensity to reach the surface of its event horizon and escape. Hawking radiation (so-far undetected particles and photons thought to be emitted from the proximity of black holes) would not circumvent the information paradox; it could reveal only the mass, angular momentum, and electric charge of classic black holes.

He also demonstrated, by simultaneous measurements at Durham's Observatory and science site (960m apart) that charge can be emitted by steam locomotives and power lines and that these electrical structures remain identifiable whilst being carried by the wind. Chalmers died following a short illness in 1967. After this, the group was led at Durham by Walter Hutchinson, broadening to include collaboration between Durham's atmospheric physicists and astronomers. On 26 May 2017 the Royal Meteorological Society's Special Interest Group on Atmospheric Electricity held a discussion meeting at Durham's Physics Department to mark the 50th anniversary year of Chalmers' death, which included contributions by his former co-workers, and has inspired a biographical article.

Every 12 July many of them celebrate by lighting a bonfire in the centre of the estate. In 2007 there was a legal threat over the inclusion of hundreds of tyres in the bonfire with the fear that excessive toxic fumes would be emitted, however it was not possible to establish who had been involved in placing them there, and the bonfire was allowed to go ahead. On the Ballycraigy estate is a memorial garden dedicated to Billy Wright, leader of the Loyalist Volunteer Force paramilitary organisation. Ballycraigy Manor, a country house with a tower and crenellated battlements was built here in 1869, the residence of James Chaine, a businessman involved in shipping and a Conservative Party politician.

Viral luciferase expression in a mouse tumour Both in the laboratory and in the clinic it is useful to have a simple means of identifying cells infected by the experimental virus. This can be done by equipping the virus with "reporter genes" not normally present in viral genomes, which encode easily identifiable protein markers. One example of such proteins is GFP (green fluorescent protein) which, when present in infected cells, will cause a fluorescent green light to be emitted when stimulated by blue light. An advantage of this method is that it can be used on live cells and in patients with superficial infected lesions, it enables rapid non-invasive confirmation of viral infection.

The Integrated Waste Management Facilities develops with advanced incineration as its core along with recycling plant for recovering recyclable wastes from MSW. Apart from alleviating the landfill load, nearly hundred tons of useful materials such as metals will be recovered each day. The IWMF can also recover energy from the waste and convert the energy into electricity supplying more than 100,000 households, in turn reducing carbon dioxide emission by 440,000 tons each year (EDP, 2011). Yet, local concerns are still growing with respect to whether pollutant gases and dust particles harmful to health and environment will be emitted, and the price of incinerators run high, costing $14.9 billion for construction and $353 million a year for operations (Cheung, 2012).

The automation for the screen deployment was provided by Kinesys UK."U2 360" Kinesys UK project The LED segments of the screen are weather-resistant. U2 announced that it would purchase carbon offsets to take into consideration the environmental impact of the large production, which has been estimated to be up to 65,000 tonnes of carbon dioxide; approximately the same amount that would be emitted in flying a passenger plane 34 million miles. In addition to the carbon offsets, the band also set up a page on PickupPal so that people could carpool to concerts in an attempt to lower the carbon footprint. Additionally they launched a fan travel carbon offset program in partnership with Offset Options.

The game includes a natural language text parser shared with other Skotos games, such as Lovecraft Country: Arkham by Night and the Lazarus Project, so that commands can be entered more like typical sentences rather than as computer-oriented commands. Castle Marrach does not allow for free-emoting, which means players are restricted in their actions to what the parser understands. The game's parser has an extensive adverb verb noun system, which allows players to adjust items, their own bodies (and body parts), and the bodies (and body parts) of others. A command such as, shyly hold bob's hand would be accepted by the parser and be emitted as Jane shyly holds Bob's hand.

While the production and consumption of CFCs are regulated under the Montreal Protocol, emissions from existing banks of CFCs are not regulated under the agreement. In 2002, there were an estimated 5,791 kilotons of CFCs in existing products such as refrigerators, air conditioners, aerosol cans and others.Campbell, Nick et al. "HFCs and PFCs: Current and Future Supply, Demand and Emissions, plus Emissions of CFCs, HCFCs and Halons", Ch. 11 in IPCC/TEAP Special Report: Safeguarding the Ozone Layer and the Global Climate System Approximately one- third of these CFCs are projected to be emitted over the next decade if action is not taken, posing a threat to both the ozone layer and the climate.

It calls for global emissions to be capped at their current level and then brought down year by year at a rate fast enough to prevent catastrophic climate change. Each year, the emissions tonnage involved would be shared equally amongst the Earth's adult population, each of whom would receive a certificate representing their individual entitlement. The recipients would then sell their certificates through the banking system to oil, coal and gas producers who would need to acquire enough of them to cover the carbon dioxide emissions that would be emitted from all of the fossil fuel they sold. Everyone would receive at least partial compensation for the higher cost of fossil fuels that limiting their availability would necessarily involve.

When puberty approaches, children should be taught the signs of puberty and the characteristics which distinguish men from women, and the types of discharge that may be emitted from the front passage of both sexes. They should also be taught the rulings on wudoo’ and ghusl, paying attention to the phrases used in teaching and ensuring that it is taught according to what the child needs to know. Munajjid has maintained two as important matters which should begin at a very early age (contradiction of earlier saying about sex education) that have a basic connection to the issue of sex education. They are: # The necessity for the boy or girl to be able to distinguish between male and female.

The principal source of noise in DFAs is Amplified Spontaneous Emission (ASE), which has a spectrum approximately the same as the gain spectrum of the amplifier. Noise figure in an ideal DFA is 3 dB, while practical amplifiers can have noise figure as large as 6–8 dB. As well as decaying via stimulated emission, electrons in the upper energy level can also decay by spontaneous emission, which occurs at random, depending upon the glass structure and inversion level. Photons are emitted spontaneously in all directions, but a proportion of those will be emitted in a direction that falls within the numerical aperture of the fiber and are thus captured and guided by the fiber.

The electrons tunnel to the next period of the structure and the process repeats. Additionally, in semiconductor laser diodes, electrons and holes are annihilated after recombining across the band gap and can play no further part in photon generation. However, in a unipolar QCL, once an electron has undergone an intersubband transition and emitted a photon in one period of the superlattice, it can tunnel into the next period of the structure where another photon can be emitted. This process of a single electron causing the emission of multiple photons as it traverses through the QCL structure gives rise to the name cascade and makes a quantum efficiency of greater than unity possible which leads to higher output powers than semiconductor laser diodes.

In his 2013 campaign, McAuliffe claimed to support tougher safety requirements on coal plants. He also announced his support for the Environmental Protection Agency's Clean Power Plan, which would limit the amount of carbon dioxide that could be emitted by power plants and therefore make it difficult for new coal-fired plants to be built and for old ones to remain in operation. In 2017, McAuliffe filed a request with the federal Bureau of Ocean Energy Management to request that Virginia's coastal areas be excluded from a program to open up the East Coast to offshore drilling. In May 2017, McAuliffe issued an executive order for Virginia to become a member of the Regional Greenhouse Gas Initiative (RGGI) to cut greenhouse gases from power plants.

In 1902, Philipp Lenard discovered that the maximum possible energy of an ejected electron is related to the frequency of the light, not to its intensity: if the frequency is too low, no electrons are ejected regardless of the intensity. Strong beams of light toward the red end of the spectrum might produce no electrical potential at all, while weak beams of light toward the violet end of the spectrum would produce higher and higher voltages. The lowest frequency of light that can cause electrons to be emitted, called the threshold frequency, is different for different metals. This observation is at odds with classical electromagnetism, which predicts that the electron's energy should be proportional to the intensity of the incident radiation.

Propellant atoms are injected into the discharge chamber and are ionized by electron bombardment, forming a plasma. There are several ways of producing the energetic electrons for the discharge: electrons can be emitted from a hollow cathode and accelerated by potential difference with the anode; the electrons can be accelerated by an oscillating electric field induced by an alternating electromagnet, which results in a self-sustaining discharge and omits any cathode (radio frequency ion thruster); and microwave heating. The positively charged ions diffuse towards the chamber's extraction system (2 or 3 multi-aperture grids). After ions enter the plasma sheath at a grid hole, they are accelerated by the potential difference between the first and second grids (called the screen and accelerator grids, respectively).

Such a wave must be emitted \tau_1=L_U/v_f times unit earlier, at point P' on the figure. Since the vehicle number does not change along this characteristic, we see that the vehicle number at the M-detector calculated from conditions upstream is the same as that observed at the upstream detector \tau_1 time units earlier. Since \tau_1 is independent of the traffic state (it is a constant), this result is equivalent to shifting the smoothed N-curve of the upstream detector (curve U of Figure 3) to the right by an amount \tau_1. Downstream. Likewise, since the state over the downstream detector is queued, there will be a wave reaching P from a location P_2 with wave velocity -w<0.

The Bayport Terminal was controversial since before its construction because of concerns raised about environmental impact and the general suitability of the site. The United States Army Corps of Engineers approved the permit, but stated in the Environmental Impact Statement that unavoidable impacts of increased noise in the area, increased levels of nitrous oxides, sulfur dioxide, carbon dioxide, and cancer causing particulate matter would be emitted by the terminal. Homes are within of the docks. Due to the prevailing southeast wind and the proximity of the residents, the Corps of Engineers recommended a sound wall to block sound levels that they estimated to be as high as 70 dBA (as of 2010 the terminal was only approximately 30% in operation yet produced levels of 65 dBA).

Electrons that are bound in atoms, molecules and solids each occupy distinct states of well-defined binding energies. When light quanta deliver more than this amount of energy to an individual electron, the electron may be emitted into free space with excess (kinetic) energy that is h u higher than the electron's binding energy. The distribution of kinetic energies thus reflects the distribution of the binding energies of the electrons in the atomic, molecular or crystalline system: an electron emitted from the state at binding energy E_B is found at kinetic energy E_k=h u-E_B. This distribution is one of the main characteristics of the quantum system, and can be used for further studies in quantum chemistry and quantum physics.

The central assumption behind his new derivation, presented to the DPG on 14 December 1900, was the supposition, now known as the Planck postulate, that electromagnetic energy could be emitted only in quantized form, in other words, the energy could only be a multiple of an elementary unit: :E = h u where is Planck's constant, also known as Planck's action quantum (introduced already in 1899), and is the frequency of the radiation. Note that the elementary units of energy discussed here are represented by and not simply by . Physicists now call these quanta photons, and a photon of frequency will have its own specific and unique energy. The total energy at that frequency is then equal to multiplied by the number of photons at that frequency.

Stimulating these mineral grains using either light (blue or green for OSL; infrared for IRSL) or heat (for TL) causes a luminescence signal to be emitted as the stored unstable electron energy is released, the intensity of which varies depending on the amount of radiation absorbed during burial and specific properties of the mineral. Most luminescence dating methods rely on the assumption that the mineral grains were sufficiently "bleached" at the time of the event being dated. For example, in quartz a short daylight exposure in the range of 1–100 seconds before burial is sufficient to effectively “reset” the OSL dating clock. This is usually, but not always, the case with aeolian deposits, such as sand dunes and loess, and some water-laid deposits.

Emissions budgets are relevant to climate change mitigation because they indicate a finite amount of carbon dioxide that can be emitted over time, before resulting in dangerous levels of global warming. Change in global temperature is independent from the geographic location of these emissions, and is largely independent of the timing of these emissions. In line with the 2018 Special report on Global Warming of 1.5° C by the IPCC, the Mercator Research Institute on Global Commons and Climate Change estimates that the budget associated with 1.5 °C degrees of warming will be exhausted in 2028 if emissions remain on the current level of the late 2010s. Beyond a 1.5°C temperature rise, the risk of long-lasting and irreversible consequences of climate change increases.

Feedback (Rückkopplung) in this case refers to tape delay, through which music played by the soloist is made to return after periods of time specified in six different form plans, one of which is to be chosen for any performance . The performer is given six pages of conventionally notated material constituting the "content" of the work, and selects material according to certain criteria, playing it into a stereo pair of microphones that feed into the tape-loop system. Three assistants choose one or both recording channels, the degree of feedback, and the level of sound to be emitted from the speakers. This results in a regular though transformed periodic recurrence of the initial material, while the soloist adds new material over it.

The observation was heralded as inaugurating a revolutionary era of gravitational- wave astronomy. Prior to this detection, astrophysicists and cosmologists were able to make observations based upon electromagnetic radiation (including visible light, X-rays, microwave, radio waves, gamma rays) and particle-like entities (cosmic rays, stellar winds, neutrinos, and so on). These have significant limitations – light and other radiation may not be emitted by many kinds of objects, and can also be obscured or hidden behind other objects. Objects such as galaxies and nebulae can also absorb, re-emit, or modify light generated within or behind them, and compact stars or exotic stars may contain material which is dark and radio silent, and as a result there is little evidence of their presence other than through their gravitational interactions.

In addition to reproducing certain in-game sound effects that reflect the on- screen action, the Wii Remote speaker can also function as a voice receiver through which non-player characters can speak to the player with long-distance telecommunication, featured in games like Red Steel, Real Heroes: Firefighter and GoldenEye 007. Some party games and hotseat multiplayer games also utilize the speaker to indicate changes between player turns. The volume can be changed or muted with the "Home" button and selecting the corresponding controller icon at the bottom of the screen; if the speaker is muted, any sounds intended to be emitted from the speaker will come from the television in most cases. The rumble feature can also be switched on or off using the Home Menu.

Baade and Zwicky correctly proposed at that time that the release of the gravitational binding energy of the neutron stars powers the supernova: "In the supernova process, mass in bulk is annihilated". Neutron stars were thought to be too faint to be detectable and little work was done on them until November 1967, when Franco Pacini pointed out that if the neutron stars were spinning and had large magnetic fields, then electromagnetic waves would be emitted. Unbeknown to him, radio astronomer Antony Hewish and his research assistant Jocelyn Bell at Cambridge were shortly to detect radio pulses from stars that are now believed to be highly magnetized, rapidly spinning neutron stars, known as pulsars. In 1965, Antony Hewish and Samuel Okoye discovered "an unusual source of high radio brightness temperature in the Crab Nebula".

The X-ray emission from Vega is very low, demonstrating that the corona for this star must be very weak or non-existent. However, as the pole of Vega is facing Earth and a polar coronal hole may be present, confirmation of a corona as the likely source of the X-rays detected from Vega (or the region very close to Vega) may be difficult as most of any coronal X-rays would not be emitted along the line of sight. Using spectropolarimetry, a magnetic field has been detected on the surface of Vega by a team of astronomers at the Observatoire du Pic du Midi. This is the first such detection of a magnetic field on a spectral class A star that is not an Ap chemically peculiar star.

The probability "wave" can be said to "pass through space" because the probability values that one can compute from its mathematical representation are dependent on time. One cannot speak of the location of any particle such as a photon between the time it is emitted and the time it is detected simply because in order to say that something is located somewhere at a certain time one has to detect it. The requirement for the eventual appearance of an interference pattern is that particles be emitted, and that there be a screen with at least two distinct paths for the particle to take from the emitter to the detection screen. Experiments observe nothing whatsoever between the time of emission of the particle and its arrival at the detection screen.

The Auger effect is an electronic process at the heart of AES resulting from the inter- and intrastate transitions of electrons in an excited atom. When an atom is probed by an external mechanism, such as a photon or a beam of electrons with energies in the range of several eV to 50 keV, a core state electron can be removed leaving behind a hole. As this is an unstable state, the core hole can be filled by an outer shell electron, whereby the electron moving to the lower energy level loses an amount of energy equal to the difference in orbital energies. The transition energy can be coupled to a second outer shell electron, which will be emitted from the atom if the transferred energy is greater than the orbital binding energy.

General exhaust ventilation (GEV), also called dilution ventilation, is different from local exhaust ventilation because instead of capturing emissions at their source and removing them from the air, general exhaust ventilation allows the contaminant to be emitted into the workplace air and then dilutes the concentration of the contaminant to an acceptable level. GEV is inefficient and costly as compared to local exhaust ventilation, and given the lack of established exposure limits for most nanomaterials, they are not recommended to be relied upon for controlling exposure. However, GEV can provide negative room pressure to prevent contaminants from exiting the room. The use of supply and exhaust air throughout the facility can provide pressurization schemes that reduce the number of workers exposed to potentially hazardous materials, for example keeping production areas at a negative pressure with respect to nearby areas.

In both nuclear and chemical reactions, such energy represents the difference in binding energies of electrons in atoms (for chemistry) or between nucleons in nuclei (in atomic reactions). In both cases, the mass difference between reactants and (cooled) products measures the mass of heat and light which will escape the reaction, and thus (using the equation) give the equivalent energy of heat and light which may be emitted if the reaction proceeds. In chemistry, the mass differences associated with the emitted energy are around 10−9 of the molecular mass. However, in nuclear reactions the energies are so large that they are associated with mass differences, which can be estimated in advance, if the products and reactants have been weighed (atoms can be weighed indirectly by using atomic masses, which are always the same for each nuclide).

Also, these regenerations are portrayed as violent discharges that could harm anyone nearby, to the point where the most powerful occurrences, seen in "The End of Time" and "The Time of the Doctor", were able to destroy the Tardis interior and send out a shockwave that destroyed a Dalek ship along with several troops respectively. Each time there was a regeneration with people nearby, either the Doctor or his companions had everyone present get away from the person who was regenerating to avoid them being harmed. In smaller discharges, regeneration was far less harmful and could be emitted from the hand in wisps of golden regeneration energy, which was capable of healing the injuries of others. The subsequent Children in Need special established that there was residual "regeneration energy" in a gaseous state after a transformation that had to be expelled through the mouth.

As the electron decays down to the ground state (minimum energy level), energy conservation requires radiation to be emitted by the impurity ion. This emission has discrete values of energy, or wavelength, which correspond to the energy differences between the initial and final atomic levels of a particular electron transition. For example, consider charge exchange between a deuterium atom and a C+6 ion: if the electron is transferred to the n=7 energy level of the carbon ion, then the ion will emit radiation at discrete energies given by the difference in energy between the n=7 and n=6 levels, the n=6 and n=5 levels, the n=5 and n=4 levels, and so on (down to n=1). This line emission is Doppler-broadened as a result of ion thermal motion, and Doppler-shifted as a result of ion flow.

Many modern hospital beds are able to feature a bed exit alarm whereby a pressure pad on or in the mattress arms an audible alert when a weight such as a patient is placed on it, and activating the full alarm once this weight is removed. This is helpful to hospital staff or caregivers monitoring any number of patients from a distance (such as a nurse's station) as the alarm will trigger in the event of a patient (especially the elderly or memory impaired) falling out of the bed or wandering off unsupervised. This alarm can be emitted solely from the bed itself or connected to the nurse call bell/light or hospital phone/paging system. Also some beds can feature a multi-zone bed exit alarm which can alert the staff when the patient start moving in the bed and before the actual exit which is necessary for some cases.

Committee on Climate Change The Committee on Climate Change (CCC) is an independent non-departmental public body, formed under the Climate Change Act (2008) to advise the United Kingdom and devolved Governments and Parliaments on tackling and preparing for climate change. The Committee provides advice on setting carbon budgets (for the UK Government carbon budgets are designed to place a limit or ceiling on the level of economy-wide emissions that can be emitted in a five-year period), and reports regularly to the Parliaments and Assemblies on the progress made in reducing greenhouse gas emissions. The CCC has recommended net zero greenhouse gas emissions by the United Kingdom by 2050 and the Energy and Climate Intelligence Unit (ECIU) has said it would be affordable. On 27 June 2019 the British Parliament amended the Climate Change Act (2008) to include a commitment to net zero emissions by 2050.

The nucleus can also be modified through bombardment by high energy subatomic particles or photons. If this modifies the number of protons in a nucleus, the atom changes to a different chemical element. If the mass of the nucleus following a fusion reaction is less than the sum of the masses of the separate particles, then the difference between these two values can be emitted as a type of usable energy (such as a gamma ray, or the kinetic energy of a beta particle), as described by Albert Einstein's mass-energy equivalence formula, E=mc^2, where m is the mass loss and c is the speed of light. This deficit is part of the binding energy of the new nucleus, and it is the non-recoverable loss of the energy that causes the fused particles to remain together in a state that requires this energy to separate.

In order to receive a signal strong enough to index with, the beam had to be left on at all times, which reduced contrast ratio in relation to conventional tubes, since some light still had to be emitted for the electron beam to be tracked by the photodiodes. The beam-index tube bears some resemblance to two other types of television tubes which also used vertical stripes of colored phosphor instead of dots or grids. The Chromatron used two sets of fine wires suspended behind the display area to electrically focus its single beam, one set of wires pulling the beam towards the red side and the other towards the blue. The grids were aligned so the beam would normally focus onto the green stripe in the middle, but by varying the relative voltage between the two the beam could accurately hit the colored stripes.

The carbon footprint explained A carbon footprint is the total greenhouse gas (GHG) emissions caused by an individual, event, organization, service, or product, expressed as carbon dioxide equivalent. Greenhouse gases, including the carbon-containing gases carbon dioxide and methane, can be emitted through the burning of fossil fuels, land clearance and the production and consumption of food, manufactured goods, materials, wood, roads, buildings, transportation and other services. In most cases, the total carbon footprint cannot be calculated exactly because of inadequate knowledge of and data about the complex interactions between contributing processes, including the influence of natural processes that store or release carbon dioxide. For this reason, Wright, Kemp, and Williams proposed the following definition of a carbon footprint: The global average annual carbon footprint per person in the late 2010s was 0.7 tonnes CO2eq food, 1.1 tonnes from the home, 0.8 tonnes transport and 0.8 tonnes other.

By demanding that high-frequency light must be emitted by an oscillator of equal frequency, and further requiring that this oscillator occupy higher energy than one of a lesser frequency, Planck avoided any catastrophe, giving an equal partition to high-frequency oscillators produced successively fewer oscillators and less emitted light. And as in the Maxwell–Boltzmann distribution, the low-frequency, low-energy oscillators were suppressed by the onslaught of thermal jiggling from higher energy oscillators, which necessarily increased their energy and frequency. The most revolutionary aspect of Planck's treatment of the black body is that it inherently relies on an integer number of oscillators in thermal equilibrium with the electromagnetic field. These oscillators give their entire energy to the electromagnetic field, creating a quantum of light, as often as they are excited by the electromagnetic field, absorbing a quantum of light and beginning to oscillate at the corresponding frequency.

This nuclear reaction 14N (n,p) 14C continually happens in the Earth's atmosphere, forming equilibrium amounts of the radionuclide 14C. Most (n,p) reactions have threshold neutron energies below which the reaction cannot take place as a result of the charged particle in the exit channel requiring energy (usually more than a MeV) to overcome the Coulomb barrier experienced by the emitted proton. The (n,p) nuclear reaction 14N (n,p) 14C is an exception to this rule, and is exothermic – it can take place at all incident neutron energies. The 14N (n,p) 14C nuclear reaction is responsible for most of the radiation dose delivered to the human body by thermal neutrons – these thermal neutrons are absorbed by the nitrogen 14N in proteins, causing a proton to be emitted; the emitted proton deposits its kinetic energy over a very short distance in the body tissue, thereby depositing radiation dose.

Of this paper and Maxwell's related works, fellow physicist Richard Feynman said: "From the long view of this history of mankind – seen from, say, 10,000 years from now – there can be little doubt that the most significant event of the 19th century will be judged as Maxwell's discovery of the laws of electromagnetism." Albert Einstein used Maxwell's equations as the starting point for his Special Theory of Relativity, presented in The Electrodynamics of Moving Bodies, a paper produced during his 1905 Annus Mirabilis. In it is stated: : "the same laws of electrodynamics and optics will be valid for all frames of reference for which the equations of mechanics hold good" and : "Any ray of light moves in the "stationary" system of co-ordinates with the determined velocity c, whether the ray be emitted by a stationary or by a moving body." Maxwell's equations can also be derived by extending general relativity into five physical dimensions.

In 1915 Bohr published a paper noting that the measurements of Franck and Hertz were more consistent with the assumption of quantum levels in his own model for atoms. Kragh quotes a sentence from one of Bohr's 1915 papers in which he discusses the 1914 papers by Franck and Hertz: "It seems that their experiment may possibly be consistent with the assumption that this voltage (4.9 V) corresponds only to the transition from the normal state to some other stationary state of the neutral atom." In the Bohr model, the collision excited an internal electron within the atom from its lowest level to the first quantum level above it. The Bohr model also predicted that light would be emitted as the internal electron returned from its excited quantum level to the lowest one; its wavelength corresponded to the energy difference of the atom's internal levels, which has been called the Bohr relation.

To illustrate the significance of these formulae, the annihilation of a particle with its antiparticle in free space must result in the creation of at least two photons for the following reason. In the center of momentum frame, the colliding antiparticles have no net momentum, whereas a single photon always has momentum (since, as we have seen, it is determined by the photon's frequency or wavelength, which cannot be zero). Hence, conservation of momentum (or equivalently, translational invariance) requires that at least two photons are created, with zero net momentum. (However, it is possible if the system interacts with another particle or field for the annihilation to produce one photon, as when a positron annihilates with a bound atomic electron, it is possible for only one photon to be emitted, as the nuclear Coulomb field breaks translational symmetry.) The energy of the two photons, or, equivalently, their frequency, may be determined from conservation of four-momentum.

According to Bragg's law, when an X-ray beam of wavelength "λ" strikes the surface of a crystal at an angle "Θ" and the crystal has atomic lattice planes a distance "d" apart, then constructive interference will result in a beam of diffracted x-rays that will be emitted from the crystal at angle "Θ" if ::nλ = 2d sinΘ, where n is an integer. This means that a crystal with a known lattice size will deflect a beam of x-rays from a specific type of sample at a pre-determined angle. The x-ray beam can be measured by placing a detector (usually a scintillation counter or a proportional counter) in the path of the deflected beam and, since each element has a distinctive x-ray wavelength, multiple elements can be determined by having multiple crystals and multiple detectors. To improve accuracy the x-ray beams are usually collimated by parallel copper blades called a Söller collimator.

Thilo Schaefer, climate and energy expert at the Cologne Institute for Economic Research (IW), comments that "it looks like the government forgot that the energy sector and industry already participate in the European emissions trading system... in the end, it will simply become more expensive for the affected sectors, but they won't save a single extra ton of ... because the emissions saved by German sectors can be emitted by other states". Simone Peter, co-chair of the Green Party, said "this is not a good plan anymore, it has become an empty shell, because the ministerial colleagues of [environment minister] Hendricks have removed anything that could be of relevance – be it the coal exit, the end of the combustion engine, or a transition in agriculture". Klaus Töpfer, founding director of the Institute for Advanced Sustainability Studies (IASS), said "this plan is certainly not yet capable of securing the German contribution to the Paris Climate Agreement. This will require more work".

University of Maryland School of Public Policy professor and former Chief Economist for the World Bank Herman E. Daly (working from theory initially developed by Romanian economist Nicholas Georgescu-Roegen and laid out in his 1971 opus "The Entropy Law and the Economic Process") suggests the following three operational rules defining the condition of ecological (thermodynamic) sustainability: #Renewable resources such as fish, soil, and groundwater must be used no faster than the rate at which they regenerate. #Nonrenewable resources such as minerals and fossil fuels must be used no faster than renewable substitutes for them can be put into place. #Pollution and wastes must be emitted no faster than natural systems can absorb them, recycle them, or render them harmless. Some commentators have argued that the "Daly Rules", being based on ecological theory and the Laws of Thermodynamics, should perhaps be considered implicit or foundational for the many other systems that are advocated, and are thus the most straightforward system for operationalization of the Bruntland Definition.

Drawing on research from the Potsdam Institute for Climate Impact Research, Carbon Tracker's reports showed that the world's reserves and resources of coal, oil and gas, if burned, would emit more than three times this amount: approximately 2800 gigatonnes. This raises the possibility that, by financing the development and production of fossil fuels that might never be consumed, investors are exposed to the risk of "stranded assets", rendered unprofitable by climate regulations and technological alternatives such as renewable energy.At about that time, the carbon budget idea was plucked from academia by Carbon Tracker, a small London think-tank founded by Mark Campanale, one of the city’s first sustainable investment analysts. Applying the research to the world’s coal mines, oil wells and gasfields, the think-tank said that to have even a small chance of meeting the 2C target, only 565 gigatonnes of CO2 could be emitted up to 2050. But the known fossil fuel reserves of energy and mining companies were equal to 2,795 gigatonnes of CO2. So if the world ever took serious action to meet the 2C goal, most of those reserves would become “unburnable” stranded assets.
