div style float right border solid 10px white Renal worksheet div Urine sodium is a measurement of the level of sodium in the urine . Because the hypothalamus osmoreceptor system ordinarily works well to cause drinking or urination to restore the body s sodium concentrations to normal, this system can be used in medical treatment to regulate the body s total fluid content, by first controlling the body s sodium content. Thus, when a powerful diuretic drug is given which causes the kidneys to excrete sodium, the effect is accompanied by an excretion of body water water loss accompanies sodium loss . This happens because the kidney is unable to efficiently retain water while excreting large amounts of sodium. In addition, after sodium excretion, the osmoreceptor system may sense lowered sodium concentration in the blood and then direct compensatory urinary water loss in order to correct the hyponatremia hyponatremic low blood sodium state.

FASOR stands for Frequency Addition Source of Optical Radiation, and for this system it is two single mode and single frequency solid state IR lasers, 1.064 and 1.319 micrometres, that are frequency summed in a LBO crystal within a doubly resonant cavity. Sodium layer refers to a layer within the Earth s mesosphere of unbound, non ion ized atom s of sodium . The altitude of this layer is usually located between 80&ndash 105 km 50&ndash 65 miles and has a depth of about 5 km 3 miles . The sodium comes from the ablation of meteors . Atmospheric sodium below this layer is normally chemically bound in compounds such as sodium oxide , while above the layer the atoms tend to be ionized. Atoms of sodium in this layer are typically in an excited state, and radiate weakly at a wavelengths around 589 nm, which is in the yellow portion of the spectrum. These radiation bands are known as the Fraunhofer lines sodium D lines . The resulting radiation has been termed air glow night glow . Astronomer s have found the sodium layer to be useful for creating an artificial laser guide star in the upper atmosphere. The star is used by adaptive optics to compensate for movements in the atmosphere. As a result, optical telescope s can perform much closer to their theoretical limit of resolution. The sodium layer was first discovered in 1929. In 1939 the United Kingdom British United States American geophysicist Sydney Chapman astronomer Sydney Chapman proposed a reaction cycle theory to explain the night glow phenomenon.
