The Margules activity model is a simple thermodynamic model for the excess Gibbs free energy of a liquid mixture introduced in 1895 by Max Margules. [1] [2] After Lewis had introduced the concept of the activity coefficient, the model could be used to derive an expression for the activity coefficients of a compound i in a liquid, a measure for the deviation from ideal solubility, also known as ...
The limiting oxygen concentration (LOC), [1] also known as the minimum oxygen concentration (MOC), [2] is defined as the limiting concentration of oxygen below which combustion is not possible, independent of the concentration of fuel. It is expressed in units of volume percent of oxygen. The LOC varies with pressure and temperature.
In four different English-language countries of recipe and measuring-utensil markets, approximate cup volumes range from 236.59 to 284.1 milliliters (mL). Adaptation of volumetric recipes can be made with density approximations:
The 267 was introduced in 1979 for the GM F-body (Camaro), G-body (Chevrolet Monte Carlo, El Camino), A-body (Malibu Classic, 1979–1981) and also used on GM B-body cars (Impala and Caprice models). The 4.4 L; 267.8 cu in (4,389 cc) engine had the 350's crankshaft stroke of 3.48 in (88.4 mm) and the smallest bore of any small-block, 3.5 in (88 ...
A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a nearly constant volume independent of pressure. It is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape.
Insects do not have lungs; oxygen and other gases, such as carbon dioxide, pass through their exoskeleton via tiny valves called spiracles. Insects also lack closed blood vessels ; instead, they have a long, thin, perforated tube along the top of the body (called the "dorsal aorta") that functions like a heart, and pumps haemolymph toward the ...
People v. Murray (The People of the State of California v.Conrad Robert Murray) is the name of the American criminal trial of Michael Jackson's personal physician, Conrad Murray, who was charged with involuntary manslaughter for the pop singer's death on June 25, 2009, from a dose of the general anesthetic propofol.

It is a halogenated ether in form of a clear, colorless liquid, and its vapor has a strong fruity aroma. It is miscible with ethanol, acetone, chloroform, diethyl ether, and fixed oils. It is soluble in rubber. [13] With a minimum alveolar concentration (MAC) of 0.16%, [58] methoxyflurane is an extremely potent anesthetic agent. It is a ...
