However, if no bleeding occurs after progesterone withdrawal, then the patient's amenorrhea is likely to be due to either a) low serum estradiol (i.e. premature ovarian failure), b) hypothalamic-pituitary axis dysfunction (such as low GNRH or low FSH that lead to low estrogen level ), c) a nonreactive endometrium, or d) a problem with the uterine outflow tract, such as cervical stenosis or uterine synechiae (Asherman's syndrome). In order to distinguish between hypoestrogenism or a uterine outflow tract problem/nonreactive endometrium, estrogen may be administered followed by a course of progestin in order to induce withdrawal bleeding. If the patient experiences withdrawal bleeding with the combined estrogen/progestin therapy, then the amenorrhea is likely due to low estrogen.

Refrigerated liquid oxygen (LOX) is given a health hazard rating of 3 (for increased risk of hyperoxia from condensed vapors, and for hazards common to cryogenic liquids such as frostbite), and all other ratings are the same as the compressed gas form.

Some of the simplest reactive transport problems can be solved analytically. Where equilibrium sorption is described by a linear distribution coefficient, for example, the sorbing solute's velocity is retarded relative to that of a nonreactive tracer; the relative velocities can be described with a retardation factor. Analytical solutions are exact solutions of the governing equations. Complex reactive transport problems are more commonly solved numerically.

The blasts react with antibodies to myeloperoxidase and antibodies to CD13, CD33, and CD34. Human leukocyte antigen (HLA)-DR is positive in most patients. Occasional cases require in situ hybridization to identify the myeloperoxidase gene315 or genomic profiling for early myeloid-associated genes.

Lithium hydride is an inorganic compound with the formula LiH. This alkali metal hydride is a colorless solid, although commercial samples are grey. Characteristic of a salt-like (ionic) hydride, it has a high melting point, and it is not soluble but reactive with all organic and protic solvents. It is soluble and nonreactive with certain molten salts such as lithium fluoride, lithium borohydride, and sodium hydride.

The catalyst is derived from molybdenum(V) chloride and tris(2-aminoethyl)amine N-substituted with three bulky hexa-isopropylterphenyl (HIPT) groups. Nitrogen adds end-on to the molybdenum atom, and the bulky HIPT substituents prevent the formation of the stable and nonreactive Mo−N=N−Mo dimer. In this isolated pocket is the . The proton donor is a pyridinium salt of weakly coordinating counter anion.

No estimate of the overall incidence of allergic reactions to tattoo pigments exists. Allergies to latex are apparently more common than to inks; many artists will use non- latex gloves when requested.

In manufacturing processes, the liquid air product is typically fractionated into its constituent gases in either liquid or gaseous form, as the oxygen is especially useful for fuel gas welding and cutting and for medical use, and the argon is useful as an oxygen-excluding shielding gas in gas tungsten arc welding. Liquid nitrogen is useful in various low-temperature applications, being nonreactive at normal temperatures (unlike oxygen), and boiling at .

One method to prepare silicon nanotubes is using a reactor employing an electric arc without the use of any catalyst. To ensure purity, the reactor is evacuated and filled with the nonreactive noble gas argon. The actual formation of the nanotubes relies on the process of chemical vapor deposition. A more common laboratory-scale method involves the use of germanium, carbon or zinc oxide nanowires as a template.

Polytetrafluoroethylene (commonly called by its DuPont brand name, Teflon) is a polymer that is used as a coating for non-stick cookware. The polymer is a polyethylene chain with fluorine atoms replacing the hydrogen atoms. The strength of the carbon-fluorine bonds makes it nonreactive to most things. Furthermore fluorine bonded to carbon tends to not form hydrogen bonds, and this along with the overall relatively weak London dispersion forces present result in Teflon poorly sticking to other substances.

The connective tissue protein elastin also has a high percentage of both glycine and alanine. Silk fibroin, considered a β-keratin, can have these two as 75–80% of the total, with 10–15% serine, with the rest having bulky side groups. The chains are antiparallel, with an alternating C → N orientation. A preponderance of amino acids with small, nonreactive side groups is characteristic of structural proteins, for which H-bonded close packing is more important than chemical specificity.

The sugar moieties are nonreactive and the DNA backbone is not broken.

The half-life of this hydrophilic nonreactive isotope makes it suitable for geologic dating in the range of 60,000 to 1 million years. Additionally, large amounts of 36Cl were produced by irradiation of seawater during atmospheric detonations of nuclear weapons between 1952 and 1958. The residence time of 36Cl in the atmosphere is about 1 week. Thus, as an event marker of 1950s water in soil and ground water, 36Cl is also useful for dating waters less than 50 years before the present.

Lightning heats the air around it breaking the bonds of starting the formation of nitrous acid. Nitrogen can be fixed by lightning that converts nitrogen gas () and oxygen gas () present in the atmosphere into (nitrogen oxides). may react with water to make nitrous acid or nitric acid, which seeps into the soil, where it makes nitrate, which is of use to plants. Nitrogen in the atmosphere is highly stable and nonreactive due to the triple bond between atoms in the molecule.

As of 2009 (in the United States) there have been no reported cases of HIV contracted from tattoos. In amateur tattooing, such as that practiced in prisons, however, there is an elevated risk of infection. Infections that can theoretically be transmitted by the use of unsterilized tattoo equipment or contaminated ink include surface infections of the skin, fungal infections, some forms of hepatitis, herpes simplex virus, HIV, staph, tetanus, and tuberculosis. Tattoo inks have been described as "remarkably nonreactive histologically".

This means that even the slightest friction can catch the raised edges and cause the paint to flake off. It must be carefully consolidated with a nonreactive adhesive, without damaging other surrounding decoration (Clarkson 47). Many other paints used at the time were also poisonous. The compositions of many paints were discovered using Raman spectroscopy, a noninvasive method of analysis that bounces light off of a given pigment and reads back the compositions based on witch wavelengths are absorbed and reflected (De 75).

Iridium-192 and Cobalt-60, , are preferred for radiography, since these are chemically nonreactive metals and can be obtained with much higher specific activities by the activation of stable cobalt or iridium in high flux reactors. As an almost purely man-made isotope, caesium-137 has been used to date wine and detect counterfeits and as a relative-dating material for assessing the age of sedimentation occurring after 1945. Caesium-137 is also used as a radioactive tracer in geologic research to measure soil erosion and deposition.

Nitrogen fixation is a process by which molecular nitrogen in the air is converted into ammonia () or related nitrogenous compounds in soil. Atmospheric nitrogen is molecular dinitrogen, a relatively nonreactive molecule that is metabolically useless to all but a few microorganisms. Biological nitrogen fixation converts into ammonia, which is metabolized by most organisms. Nitrogen fixation is essential to life because fixed inorganic nitrogen compounds are required for the biosynthesis of all nitrogen- containing organic compounds, such as amino acids and proteins, nucleoside triphosphates and nucleic acids.

This case also illustrates the features of syncope-like epileptic seizures together with other variable autonomic symptoms (emesis, respiratory abnormalities, pallor, mydriasis) in Panayiotopoulos syndrome. A 5-year-old boy at age 13 months woke up vomiting profusely and then, while he was still in bed, became unresponsive and floppy with shallow breathing for 20 minutes. Later the same night, he woke up, vomited, and then collapsed in the bath. He remained flaccid and unresponsive for 1 hour, and his mother, described him as “flat” and pale with dilated nonreactive pupils.

The high purity, moisture barrier, clarity, and sterilization compatibility of COC resins make them an excellent alternative to glass in a wide range of medical products. Breakage prevention and weight reduction are common reasons for choosing COC in these applications. COC has a very low energy and nonreactive surface, which can extend shelf life and purity of medications such as insulin and other protein drugs in applications such as vials, syringes and cartridges. The high UV transmission of COC also drives diagnostic applications such as cuvettes and microplates.

A batch of M. pudica were grown and watered daily, and 10-20 pulvini were collected from each group of pulvini reactive to touch, and pulvini unreactive to touch. To further understand the movement of the ions, the upper and lower halves of all collected pulvini underwent separate ion analysis using the x-ray fluorescence spectroscopy method. This method tracked the location of the ions by coloring them each with a different color of fluorescence dye. In terms of calcium concentrations, there was a significant difference in concentration between both halves of the pulvini, in both the reactive and nonreactive pulvini.

Current research focuses on investigating alloying and low dimensional geometries to mitigate mechanical stress during lithiation. Alloying tin with elements that do not react with lithium, such as copper, has been shown to reduce stress. As for low dimensional applications, thin films have been produced with discharge capacities of 1127 mAhg−1 with excess capacity assigned to lithium ion storage at grain boundaries and associated with defect sites. Other approaches include making nanocomposites with Cu6Sn5 at its core with a nonreactive outer shell, SnO2-c hybrids have been shown to be effective, to accommodate volume changes and overall stability over cycles.

Double-paned windows have two parallel panes (slabs of glass) with a separation of typically about 1 cm; this space is permanently sealed and filled at the time of manufacture with dry air or other dry nonreactive gas. Such windows provide a marked improvement in thermal insulation (and usually in acoustic insulation as well) and are resistant to fogging and frosting caused by temperature differential. They are widely used for residential and commercial construction in intemperate climates. Triple-paned windows have been commercially manufactured and marketed with claims of additional benefit but have not become common.

The high temperatures of cement kilns, the ability of concrete to incorporate different materials, and the stable and nonreactive nature of the concrete end product, all make cement kilns a desirable method for the destruction of hazardous waste. Hazardous wastes efficiently destroyed by cement kilns include chlorinated solvents (methylene chloride, trichloroethylene, trichloromethane, trichloroethane, carbon tetrachloride), Freon-113, polychlorinated biphenyls (PCBs), dioxin, waste oil, and used hydrocarbon solvents. Whatever undesirable materials are not destroyed are locked in the finished concrete, a stable material with low permeability. Hydrocarbon waste and used tires contribute to the kiln heat, and reduces fuel use.

Overall, there is enough concrete in the dam to pave a two-lane highway from San Francisco to New York. Concrete cores were removed from the dam for testing in 1995; they showed that "Hoover Dam's concrete has continued to slowly gain strength" and the dam is composed of a "durable concrete having a compressive strength exceeding the range typically found in normal mass concrete". Hoover Dam concrete is not subject to alkali–silica reaction (ASR), as the Hoover Dam builders happened to use nonreactive aggregate, unlike that at downstream Parker Dam, where ASR has caused measurable deterioration.

These reagents are particularly useful in biological systems. Specially-designed nonreactive radical molecules can attach to specific sites in a biological cell, and EPR spectra can then give information on the environment of these so-called spin labels or spin probes. Spin-labeled fatty acids have been extensively used to study dynamic organisation of lipids in biological membranes, lipid-protein interactions and temperature of transition of gel to liquid crystalline phases. A type of dosimetry system has been designed for reference standards and routine use in medicine, based on EPR signals of radicals from irradiated polycrystalline α-alanine (the alanine deamination radical, the hydrogen abstraction radical, and the radical).

If the inorganic component has nonreactive organic groups attached to its surface and it can be dissolved in a monomer which is subsequently polymerized, the resulting material after the organic polymerization, is a blend. In this case the inorganic component interact only weakly or not at all with the organic polymer; hence, a class I material is formed. Homogeneous materials are only obtained in this case if agglomeration of the inorganic components in the organic environment is prevented. This can be achieved if the interactions between the inorganic components and the monomers are better or at least the same as between the inorganic components.

The overall reaction is: O.+\; O3 \to 2O2 This has been a significant impact of the use of CFCs on the upper stratosphere, however many countries have agreed to ban the use of CFCs. The nonreactive nature of CFC's allows them to pass into the stratosphere, where they undergo photo-dissociation to form Cl radicals. These then readily form chlorine monoxide, and this cycle can continue until two radicals react to form dichlorine monoxide, terminating the radical reaction. Because the concentration of CFCs in atmosphere is very low, the probability of a terminating reaction is exceedingly low, meaning each radical can decompose many thousands of molecules of ozone.

The term refrigerate after opening is an instruction on commercial preserved food products to cool the container after it has been opened and the contents exposed to open air. Moist foods are commonly preserved using canning and vacuum sealing to kill off any bacteria and molds, and to prevent further growth by removing oxygen. Dry-product containers are often preserved with heating and filling the empty container spaces with an inert nonreactive gas such as nitrogen. Once opened for consumption, the product is immediately exposed to atmospheric oxygen and floating dust particles containing bacteria and mold spores, and all protections from the preservation process are immediately lost.

If the organic polymerization occurs in the presence of an inorganic material to form the hybrid material one has to distinguish between several possibilities to overcome the incompatibility of the two species. The inorganic material can either have no surface functionalization but the bare material surface; it can be modified with nonreactive organic groups (e.g. alkyl chains); or it can contain reactive surface groups such as polymerizable functionalities. Depending on these prerequisites the material can be pretreated, for example a pure inorganic surface can be treated with surfactants or silane coupling agents to make it compatible with the organic monomers, or functional monomers can be added that react with the surface of the inorganic material.

Macroscopic and microscopic findings from a patient who died from intestinal (bowel) gas gangrene (a) Macroscopic picture of the edematous intestinal wall with multiple submucosal and subserosal cysts (b) Histological picture of the intestinal mucosa with nonreactive necrosis (c) Gram stain of cysts with large, rod-shaped bacteria (d) Electron microscopic picture of a bacterium found in a submucosal cyst Gas gangrene (also known as clostridial myonecrosis and myonecrosis) is a bacterial infection that produces tissue gas in gangrene. This deadly form of gangrene usually is caused by Clostridium perfringens bacteria. About 1,000 cases of gas gangrene are reported yearly in the United States. Myonecrosis is a condition of necrotic damage, specific to muscle tissue.

Present vaccination strategies for SIV control and prevention in swine farms typically include the use of one of several bivalent SIV vaccines commercially available in the United States. Of the 97 recent H3N2 isolates examined, only 41 isolates had strong serologic cross-reactions with antiserum to three commercial SIV vaccines. Since the protective ability of influenza vaccines depends primarily on the closeness of the match between the vaccine virus and the epidemic virus, the presence of nonreactive H3N2 SIV variants suggests current commercial vaccines might not effectively protect pigs from infection with a majority of H3N2 viruses. The United States Department of Agriculture researchers say while pig vaccination keeps pigs from getting sick, it does not block infection or shedding of the virus.

Tg can be significantly decreased by addition of plasticizers into the polymer matrix. Smaller molecules of plasticizer embed themselves between the polymer chains, increasing the spacing and free volume, and allowing them to move past one another even at lower temperatures. Addition of plasticizer can effectively take control over polymer chain dynamics and dominate the amounts of the associated free volume so that the increased mobility of polymer ends is not apparent. The addition of nonreactive side groups to a polymer can also make the chains stand off from one another, reducing Tg. If a plastic with some desirable properties has a Tg that is too high, it can sometimes be combined with another in a copolymer or composite material with a Tg below the temperature of intended use.

When the family of noble gases was first identified at the end of the nineteenth century, none of them was observed to form any compounds and it was initially believed that they were all inert gases (as they were then known) which could not form compounds. With the development of atomic theory in the early twentieth century, their inertness was ascribed to a full valence shell of electrons which render them very chemically stable and nonreactive. All noble gases have full s and p outer electron shells (except helium, which has no p sublevel), and so do not form chemical compounds easily. Their high ionization energy and almost zero electron affinity explain their non-reactivity. In 1933, Linus Pauling predicted that the heavier noble gases would be able to form compounds with fluorine and oxygen. Specifically, he predicted the existence of krypton hexafluoride (KrF6) and xenon hexafluoride (XeF6), speculated that XeF8 might exist as an unstable compound, and suggested that xenic acid would form perxenate salts.
