Strontium chlorideEarly Cambrian geochemical fluctuations: The start of the Cambrian period is marked by fluctuations in a number of geochemical records, including Strontium, Sulfur and Carbon isotopic excursions. While these anomalies are difficult to interpret, a number of possibilities have been put forward.Project GABRIEL: Project GABRIEL refers to an investigation by the United States Atomic Energy Commission to gauge the impact of radioactive fallout resulting from nuclear warfare. GABRIEL surmised that the radioactive isotope strontium-90 (Sr-90) presented the greatest hazard to life globally.Benzo(c)thiopheneMetallocene: A metallocene is a compound typically consisting of two cyclopentadienyl anions (Cp, which is C5H5−) bound to a metal center (M) in the oxidation state II, with the resulting general formula (C5H5)2M. Closely related to the metallocenes are the metallocene derivatives, e.Isotopes of calcium: Calcium (Ca) has 24 isotopes, from 34Ca to 57Ca. There are five stable isotopes (40Ca, 42Ca, 43Ca, 44Ca and 46Ca), plus one isotope (48Ca) with such a long half-life that for all practical purposes it can be considered stable.DenosumabCalcium signaling: Calcium ions are important for cellular signalling, as once they enter the cytosol of the cytoplasm they exert allosteric regulatory effects on many enzymes and proteins. Calcium can act in signal transduction resulting from activation of ion channels or as a second messenger caused by indirect signal transduction pathways such as G protein-coupled receptors.Alkali: In chemistry, an alkali (; from Arabic: al-qaly القلي, القالي , “ashes of the saltwort”) is a basic, ionic salt of an alkali metal or alkaline earth metal chemical element. An alkali also can be defined as a base that dissolves in water.FRAX: FRAX is a diagnostic tool used to evaluate the 10-year probability of bone fracture risk. It was developed by the World Health Organization Collaborating Centre for Metabolic Bone Diseases at Sheffield University.Cancellous bone: Cancellous bone, synonymous with trabecular bone or spongy bone, is one of two types of osseous tissue that form bones. The other osseous tissue type is cortical bone also called compact bone.Femoral neck targeting: Femoral neck targeting is the process of calculating the centre of the femoral neck during hip resurfacing surgery.Comis MIHR operative technique This can be done by hand or using electronic aides.Alan S. Kornacki: Alan Stanley Kornacki (born May 4, 1952, in Bayonne, New Jersey) is an American geologist and retired Army colonel, currently the Senior Staff Geochemist at Shell International Exploration and Production Inc."...Sea pansyCalcium metabolism: Calcium metabolism refers to all the movements (and how they are regulated) of calcium atoms and ions into and out of various body compartments, such as the gut, the blood plasma, the interstitial fluids which bathe the cells in the body, the intracellular fluids, and bone. An important aspect, or component, of calcium metabolism is plasma calcium homeostasis, which describes the mechanisms whereby the concentration of calcium ions in the blood plasma is kept within very narrow limits.List of geological phenomena: A geological phenomenon is a phenomenon which is explained by or sheds light on the science of geology.Immobilized enzyme: An immobilized enzyme is an enzyme that is attached to an inert, insoluble material such as calcium alginate (produced by reacting a mixture of sodium alginate solution and enzyme solution with calcium chloride). This can provide increased resistance to changes in conditions such as pH or temperature.Kriva RekaOsseointegration: Osseointegration derives from the Greek osteon, bone, and the Latin integrare, to make whole. The term refers to the direct structural and functional connection between living bone and the surface of a load-bearing artificial implant.High-level radioactive waste management: High-level radioactive waste management concerns management and disposal of highly radioactive materials created during production of nuclear power and nuclear weapons. Radioactive waste contains a mixture of short-lived and long-lived nuclides, as well as non-radioactive nuclides.Augustine AnieboGraneledone yamana: Graneledone yamana is a species of octopus in the genus Graneledone. G.Telescoping generations: Telescoping generations can occur in parthenogenetic species, such as aphids or other life forms that have the ability to reproduce without ovum fertilization. This occurrence is characterized by a viviparous female having a daughter growing inside her that is also parthenogenetically pregnant with a daughter cell.Atomic absorption spectroscopy: Atomic absorption spectroscopy (AAS) is a spectroanalytical procedure for the quantitative determination of chemical elements using the absorption of optical radiation (light) by free atoms in the gaseous state.
