5639-0, 5640-8, 15120-9, 56478-1. Blood alcohol content ( BAC ), also called blood alcohol concentration or blood alcohol level, is a measurement of alcohol intoxication used for legal or medical purposes. [1] BAC is expressed as mass of alcohol per volume of blood. In the US and many international publications, BAC levels are written as a ...
Bacterial artificial chromosome. A bacterial artificial chromosome ( BAC) is a DNA construct, based on a functional fertility plasmid (or F-plasmid ), used for transforming and cloning in bacteria, usually E. coli. [1] [2] [3] F-plasmids play a crucial role because they contain partition genes that promote the even distribution of plasmids ...
The short-term effects of alcohol consumption range from a decrease in anxiety and motor skills and euphoria at lower doses to intoxication (drunkenness), to stupor, unconsciousness, anterograde amnesia (memory "blackouts"), and central nervous system depression at higher doses. Cell membranes are highly permeable to alcohol, so once it is in ...
An Alco-Sensor IV law enforcement grade breathalyzer. A breathalyzer or breathalyser (a portmanteau of breath and analyzer/analyser ), also called an alcohol meter, is a device for measuring breath alcohol content (BrAC). It is commonly utilized by law enforcement officers whenever they initiate traffic stops.
Alcohol by volume (abbreviated as alc/vol or ABV) is a standard measure of the volume of alcohol contained in a given volume of an alcoholic beverage, expressed as a volume percent. [1] [2] [3] It is defined as the number of millilitres (mL) of pure ethanol present in 100 mL (3.5 imp fl oz; 3.4 US fl oz) of solution at 20 °C (68 °F).
The pharmacology of ethanol involves both pharmacodynamics (how it affects the body) and pharmacokinetics (how the body processes it). In the body, ethanol primarily affects the central nervous system, acting as a depressant and causing sedation, relaxation, and decreased anxiety. The complete list of mechanisms remains an area of research, but ...
A man of 70kg has typically 6 liters of blood (SG = 1.06) and blood is 70% water. Therefore the water contained in the blood is (6 x 1.06 x 70/100) = 4.452 kg. This represents 11% of the total body water and the alcohol in blood on a pro-rata basis, is (32 X 11/100) = 3.52 gram.
