The method modulates the amplitude of a pulsed laser beam, referred to as the pump, to bring the target molecule to an excited state. This will then affect the properties of a second coherent beam, referred to as the probe, based on the interaction of the two beams with the molecule. These properties are then measured by a detector to form an ...
Intravenous therapy (abbreviated as IV therapy) is a medical technique that administers fluids, medications and nutrients directly into a person's vein.The intravenous route of administration is commonly used for rehydration or to provide nutrients for those who cannot, or will not—due to reduced mental states or otherwise—consume food or water by mouth.
Wyeth's misreading of this regulation is based on the misunderstanding that the FDA, rather than the manufacturer, bears primary responsibility for drug labeling. It is a central premise of the Food, Drug, and Cosmetic Act (FDCA) and the FDA's regulations that the manufacturer bears responsibility for the content of its label at all times. Pp ...
The BET method is widely used in materials science for the calculation of surface areas of solids by physical adsorption of gas molecules. The total surface area S t o t a l {\displaystyle S_{\mathrm {total} }} and the specific surface area S B E T {\displaystyle S_{\mathrm {BET} }} are given by
Size-exclusion chromatography, also known as molecular sieve chromatography, [1] is a chromatographic method in which molecules in solution are separated by their shape, and in some cases size. [2] It is usually applied to large molecules or macromolecular complexes such as proteins and industrial polymers . [ 3 ]
This relationship between water activity and moisture content at a given temperature is called the moisture sorption isotherm. These curves are determined experimentally and constitute the fingerprint of a food system. [2] BET theory (Brunauer-Emmett-Teller) provides a calculation to describe the physical adsorption of gas molecules on a solid ...
The Heimlich maneuver is a first-aid method recommended by most health organizations, which uses abdominal thrusts to dislodge an obstruction from a person’s windpipe. Boy, 8, Saves Choking ...
