THC-O-phosphateLunar magma ocean: According to the giant impact hypothesis a large amount of energy was liberated in the formation of the Moon and it is predicted that as a result a large portion of the Moon was once completely molten, forming a lunar magma ocean. Evidence for the magma ocean hypothesis comes from the highly anorthositic compositions of the crust in the lunar highlands, as well as the existence of rocks with a high concentration of the geochemical component referred to as KREEP.Chondrule: Chondrules in the chondrite Grassland|200px|thumb|Chondrules in the chondrite Grassland. A millimeter scale is shown.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.Nina ArvesenNebulaIsotopes 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.Meanings of minor planet names: 154001–155000: ==List of minor planets==Larix kaempferi: Larix kaempferi, known as Japanese larch or karamatsu (唐松) in Japanese) is a species of larch native to Japan, in the mountains of Chūbu and Kantō regions in central Honshū.Farjon, A.Isotope-coded affinity tag: An Isotope-coded affinity tag (ICAT) is an isotopic labeling method used for quantitative proteomics by mass spectrometry that uses chemical labeling reagents. "Rapid quantitative analysis of proteins or protein function in complex mixtures," Rudolf Hans Aebersold et al.Steptoean positive carbon isotope excursion: The Steptoean Positive Carbon Isotope Excursion (SPICE) was a geological event which occurred about 500 million years ago at the end of the Cambrian Period. The SPICE event was a sudden reversal of the anoxia (lack of oxygen) that had steadily spread throughout the oceans during the Cambrian which also affected the atmosphere.Stratosphere: The stratosphere is the second major layer of Earth's atmosphere, just above the troposphere, and below the mesosphere. It is stratified in temperature, with warmer layers higher up and cooler layers farther down.Large ornamented Ediacaran microfossil: Large ornamented Ediacaran microfossils (LOEMs) are microscopic acritarchs, usually over 100 μm in diameter, which are common in sediments of the Ediacaran period, . They largely disappear from the Ediacaran fossil record before , roughly coeval with the origin of the Ediacara biota.Hadley Centre for Climate Prediction and Research: 140px|rightIsotopic signature: An isotopic signature (also isotopic fingerprint) is a ratio of non-radiogenic 'stable isotopes', stable radiogenic isotopes, or unstable radioactive isotopes of particular elements in an investigated material. The ratios of isotopes in a sample material are measured by isotope ratio mass spectrometry.Nankai Trough gas hydrate site: Nankai Methane Hydrate Site (or Japanese Methane Hydrate R&D Program at Nankai, Nankai Trough Methane Hydrate Site) is located in the Nankai Trough, Japan.Respirometer: A respirometer is a device used to measure the rate of respiration of a living organism by measuring its rate of exchange of oxygen and/or carbon dioxide. They allow investigation into how factors such as age, chemicals or the effect of light affect the rate of respiration.Mitochondrial ROS: Mitochondrial ROS (mtROS or mROS) are reactive oxygen species (ROS) that are produced by mitochondria. Generation of mitochondrial ROS mainly takes place at the electron transport chain located on the inner mitochondrial membrane during the process of oxidative phosphorylation (OXPHOS).Outline of water: The following outline is provided as an overview of and topical guide to water:EcosystemPermissive temperature: The permissive temperature is the temperature at which a temperature sensitive mutant gene product takes on a normal, functional phenotype.http://www.Thermal ionization: Thermal ionization, also known as surface ionization or contact ionization, is a physical process whereby the atoms are desorbed from a hot surface, and in the process are spontaneously ionized.
