Argon–argon dating: Argon–argon (or 40Ar/39Ar) dating is a radiometric dating method invented to supersede potassium-argon (K/Ar) dating in accuracy. The older method required splitting samples into two for separate potassium and argon measurements, while the newer method requires only one rock fragment or mineral grain and uses a single measurement of argon isotopes.Atmospheric-pressure laser ionization: Atmospheric pressure laser ionization is an atmospheric pressure ionization method for mass spectrometry (MS). Laser light in the UV range is used to ionize molecules in a resonance-enhanced multiphoton ionization (REMPI) process.Noble gas compoundHydrogen narcosis: Hydrogen narcosis (also known as the hydrogen effect) is the psychotropic state induced by breathing hydrogen at high pressures. Hydrogen narcosis produces symptoms such as hallucinations, disorientation, and confusion, which are similar to hallucinogenic drugs.Corona treatment: Corona treatment (sometimes referred to as air plasma) is a surface modification technique that uses a low temperature corona discharge plasma to impart changes in the properties of a surface. The corona plasma is generated by the application of high voltage to an electrode that has a sharp tip.BalloonIsotopes of krypton: There are 33 known isotopes of krypton (Kr) with atomic mass numbers from 69 through 101. Naturally occurring krypton is made of six stable isotopes, two of which might theoretically be slightly radioactive, plus traces of radioisotopes that are produced by cosmic rays in the atmosphere.Chlorinated polyvinyl chlorideSentinel loop: A sentinel loop is a sign seen on a radiograph that indicates localized ileus from nearby inflammation. Simply put, it is the dilatation of a segment of large or small intestine.Volumetric heat capacity: Volumetric heat capacity (VHC), also termed volume-specific heat capacity, describes the ability of a given volume of a substance to store internal energy while undergoing a given temperature change, but without undergoing a phase transition. It is different from specific heat capacity in that the VHC is a 'per unit volume' measure of the relationship between thermal energy and temperature of a material, while the specific heat is a 'per unit mass' measure (or occasionally per molar quantity of the material).Helium–neon laser: A helium–neon laser or HeNe laser, is a type of gas laser whose gain medium consists of a mixture of helium and neon(10:1) inside of a small bore capillary tube, usually excited by a DC electrical discharge. The best-known and most widely used HeNe laser operates at a wavelength of 632.Arteriovenous oxygen difference: The arteriovenous oxygen difference, or a-vO2 diff, is the difference in the oxygen content of the blood between the arterial blood and the venous blood. It is an indication of how much oxygen is removed from the blood in capillaries as the blood circulates in the body.Gene gunAir sensitivity: Air sensitivity is a term used, particularly in chemistry, to denote the reactivity of chemical compounds with some constituent of air. Most often, reactions occur with atmospheric oxygen (O2) or water vapor (H2O),Handling and Storage of Air-Sensitive Reagents, Technical Bulletin AL-134, Sigma-Aldrich although reactions with the other constituents of air such as carbon monoxide (CO), carbon dioxide (CO2), and nitrogen (N2) are also possible.Nitrogen deficiencyNational Fire Academy: The National Fire Academy (NFA)National Fire Academy Mission Accessed: 6/12/2012 is one of two schools in the United States operated by the Federal Emergency Management Agency (FEMA) at the National Emergency Training Center (NETC) in Emmitsburg, Maryland. Operated and governed by the United States Fire Administration (USFA) as part of the U.EdemaHoneywell Uranium Hexafluoride Processing Facility: The Honeywell Uranium Hexafluoride Processing Facility, a uranium conversion facility, is located 3 km northwest of Metropolis, Illinois. The plant, Honeywell Specialty Chemicals in Metropolis, Illinois, has a nominal capacity of 15,000 tU as uranium hexafluoride per year.Richard A Neubauer: Richard Allen Neubauer (16 January 1924–11 June 2007), was a physician known for his work in the use of hyperbaric oxygen therapy.Transpulmonary pressure: Transpulmonary pressure is the difference between the alveolar pressure and the intrapleural pressure in the lungs. During human ventilation, air flows because of pressure gradients.List of countries by carbon dioxide emissionsGas laser: A gas laser is a laser in which an electric current is discharged through a gas to produce coherent light. The gas laser was the first continuous-light laser and the first laser to operate on the principle of converting electrical energy to a laser light output.Isotopes of meitnerium: Meitnerium (Mt) is a synthetic element, and thus a standard atomic mass cannot be given. Like all synthetic elements, it has no stable isotopes.Air displacement pipetteNatural nuclear fission reactorSaturation diving: Saturation diving is a diving technique that allows divers to reduce the risk of decompression sickness ("the bends") when they work at great depths for long periods of time.Laser-induced breakdown spectroscopy: Laser-induced breakdown spectroscopy (LIBS) is a type of atomic emission spectroscopy which uses a highly energetic laser pulse as the excitation source. The laser is focused to form a plasma, which atomizes and excites samples.Helium-3Lung receptor: Lung receptors sense irritation or inflammation in the bronchi and alveoli.Xenon arc lampHistory of tracheal intubation: Tracheal intubation (usually simply referred to as intubation), an invasive medical procedure, is the placement of a flexible plastic catheter into the trachea. For millennia, tracheotomy was considered the most reliable (and most risky) method of tracheal intubation.Cheyne–Stokes respirationDimefoxPolyvalent DNA gold nanoparticles: Polyvalent DNA gold nanoparticles are colloidal gold whose surface is modified with thiol capped synthetic DNA sequences. They were co-discovered by Chad Mirkin et al.Peak inspiratory pressure: Peak inspiratory pressure (PIP) is the highest level of pressure applied to the lungs during inhalation. In mechanical ventilation the number reflects a positive pressure in centimeters of water pressure (cmH2O).Anesthesia cart: Anesthesia carts are hospital devices used to store tools that are necessary for aid during procedures that require administration of anesthesia. Anesthesia refers to the use of drugs to subdue a patient's mind and prevent him or her from feeling any pain during a surgical operation.Plateau pressure: Plateau pressure (PPLAT) is the pressure applied to small airways and alveoli during positive-pressure mechanical ventilation.Morgan, Edward G.Pulmonary gas pressures: The factors that determine the values for alveolar pO2 and pCO2 are:Permissive temperature: The permissive temperature is the temperature at which a temperature sensitive mutant gene product takes on a normal, functional phenotype.http://www.Temporal analysis of products: Temporal Analysis of Products (TAP), (TAP-2), (TAP-3) is an experimental technique for studyingMatrix model: == Mathematics and physics ==Fishpaper: Fish paper or fishpaper is a strong, flexible, fibrous dielectric paper. It resists moderate heat and mechanical injury, and is often used for wrapping coils and insulating stove-top parts.Gas chromatography–mass spectrometry: right|300 px|Example of a GC-MS instrument|thumbAlkaliphile: Alkaliphiles are a class of extremophilic microbes capable of survival in alkaline (pH roughly 8.5-11) environments, growing optimally around a pH of 10.Generalizability theory: Generalizability theory, or G Theory, is a statistical framework for conceptualizing, investigating, and designing reliable observations. It is used to determine the reliability (i.Concentration effect: In the study of inhaled anesthetics, the concentration effect is the increase in the rate that the Fa(alveolar concentration)/Fi(inspired concentration) ratio rises as the alveolar concentration of that gas is increased. In simple terms, the higher the concentration of gas administered, the faster the alveolar concentration of that gas approaches the inspired concentration.
