LOINC. 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.
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 ...
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 ...
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. 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 ...
A standard drink or (in the UK) unit of alcohol is a measure of alcohol consumption representing a fixed amount of pure alcohol. The notion is used in relation to recommendations about alcohol consumption and its relative risks to health. It helps to educate alcohol users. [ 1] A hypothetical alcoholic beverage sized to one standard drink ...
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.
The Abbott-Firestone curve was first described by Ernest James Abbott and Floyd Firestone in 1933. [3] [4] It is useful for understanding the properties of sealing and bearing surfaces. It is commonly used in the engineering and manufacturing of piston cylinder bores of internal combustion engines. [5] The shape of the curve is distilled into ...
