Science / Chemistry / Stationary Phase: A stationary phase is a substance that shows different affinities for different components in a sample mixture in a separation of the mixture by chromatography. The mobile phase (a solution containing the sample) flows over or through the stationary phase to effect the separation.
Business / Human Resources (HR) / Phased Retirement: A work schedule arrangement that allows employees to gradually reduce their full-time hours over a period of time. MORE
Technology / Motors / Polyphase Motor: Two or three-phase induction motors have their windings, one for each phase, evenly divided by the same number of electrical degrees. Reversal of the two-phase motor is accomplished by reversing the c MORE
Science / Biology / Prophase: 1) The first stage of mitosis during which chromosomes condense, the nuclear envelope disappears, and the centrioles divide and migrate to opposite ends of the cell. 2) The first stage of mitosis and MORE
Technology / Computers / Quadrature Phase-Shift Keying (QPSK): A method of modulating digital signals using four phase states to code two digital bits per phase shift. MORE
Technology / Radar / Phased Array Radar: A phased array radar uses an antenna that consists of an array of antenna elements along with signal processing that allows the antenna to be steered electronically. MORE
