Aequi

Ancient people of Italy originally inhabiting the region watered by the tributaries of the Avens River (modern Velino). Long hostile to Rome, they became especially menacing in the 5th century BC, advancing to the Alban Hills. Although repulsed by the Romans in 431, the Aequi were not completely subdued by Rome until the end of the Second Samnite War (304 BC), when they received civitas

Vacuum Technology

Capacities >are available from 1/2 to 1,000 cubic feet per minute, operating from atmospheric pressure down to as low as 2 ´ 10-2 torr for single-stage pumps and less than 5 ´ 10-3 torr for two-stage pumps. The pumps develop their full speed from atmosphere to about one torr, the speed then decreasing to zero at their ultimate pressures. One device of this type, useful for pumping both liquids

Epidendrum

Genus of tropical orchids, family Orchidaceae, with about 1,000 species that are distributed from southeastern North America to central South America. Epidendrum species are primarily epiphytic (supported by other plants and having aerial roots exposed to the humid atmosphere), but some grow on rocks or in soil. Flowers are usually borne on a terminal

Differential

In mathematics, an expression based on the derivative (q.v.) of a function, useful for approximating certain values of the function. The derivative of a function at the point x0, written as f¢(x0), is defined as the limit as Dx approaches 0 of the quotient Dy/Dx, in which Dy is f(x0 + Dx) - f(x0). Because the derivative is defined as the limit, the closer Dx is to 0, the closer will be the quotient to the derivative. Therefore,
