It was inspired by Cree syllabics and is one of the writing systems in the Canadian Aboriginal syllabics Unicode range. History The Dakelh people once enjoyed extensive literacy with the script. It is recorded that it was often used to write messages on trees, and Morice published a newspaper in syllabics which was in print from 1891 to 1894. Some transcriptions of Latin and English have been recorded as well. Its usage began to decline around 1920, when the Carrier language was banned from the local schools.

  1. Carrier lifetime

    Refimprove date March 2008 A definition in semiconductor physics , carrier lifetime is defined as the average time it takes for a minority carrier to Carrier generation and recombination recombine . The process through which this is done is typically known as minority carrier recombination . The energy released due to Carrier generation and recombination recombination can be either thermal, thereby heating up the semiconductor thermal recombination or non radiative recombination , one of the sources of waste heat in semiconductor s , or released as photon s optical recombination , used in light emitting diode LEDs and semiconductor laser s . Carrier lifetime plays an important role in Bipolar junction transistor bipolar transistors and solar cells . Carrier lifetime in semiconductor lasers In semiconductor lasers, the carrier lifetime is the time it takes an electron before recombining via non radiative processes in the laser cavity. In the frame of Laser diode rate equations rate equations model , carrier lifetime is used in the charge conservation equation as the time constant of the exponential decay of carriers. The dependence of carrier lifetime on the carrier density is expressed as ref L.A. Coldren and S.W. Corzine, Diode Lasers and Photonic Integrated Circuits , Wiley Interscience, 1995 ref math frac 1 tau n N A BN CN 2 math where A, B and C are the non radiative, radiative and Auger recombination coefficients and math tau n N math is the carrier lifetime.

The purpose of the carrier is usually either to transmit the information through space as an electromagnetic wave as in radio communication , or to allow several carriers at different frequencies to share a common physical transmission medium by frequency division multiplexing as, for example, a cable television system . Frequency modulation FM and amplitude modulation AM are common modes of modulating the carrier.

    In analogue TV technology, residual carrier is the ratio of carrier level which is modulated by the maximum video signal to the unmodulated carrier level. Video signal Main Video signal Video signal VF or more formally composite video signal CVS is the signal which carries the video information as well as some auxiliary signals for synchronizing. In all systems 0 300 mV level is reserved for auxiliary signals and 300 1000 mV is reserved for video information. In monochrome TV, 300 mV or sometimes 350 mV corresponds to black and 1000 mV corresponds to white.

Private carriers may refuse to sell their services at their own discretion, whereas common carriers must treat all customers equally. Some corporations mix both systems, using common carriers and private carriage in what is called a blended operation. Private carriage usually refers to trucking, but is also found in rail and water transportation, as well as communication. Private carriage is distinguished from Trucker Types of Truck Drivers in North America independent carrier , which is an individual owner operator or trucker who may make deals with private carriers, common carriers, contract carriers, or others as he or she wishes. Private carrier may also refer to communication or communication services. Certain frequencies which are restricted to use by law enforcement are sometimes called private carriers .

Clark J.J. Clark and Harvey E. Yarnell of the US Navy. Fleet carriers instead of operating as scouts for the fleet, would operate in unison with the fleet, to ward off air attacks, and to strike opposing forces from the air. Cruisers and destroyers would protect fleet carriers. The place of fleet carriers would then displace dreadnaught s and battleship s as the preeminent assets of the surface fleet. ref Terry C Pierce, Warfighting and Disruptive Technologies , Taylor & Francis, 2005, ISBN 978 0 4157 0189 1, p. 127. ref A fleet carrier would carry over 50 aircraft, and be fast enough to keep up with other major elements of the fleet, such as cruisers and battleships. ref citation first editor Stanley editor last Sandler title World War II in the Pacific publisher Taylor & Francis year 2001 ISBN 978 0 8153 1883 5 chapter Aircraft Carriers Japanese, U.S., and British . ref In WWII, a fleet carrier usually carried three squadrons, typically, a fighter squadron, torpedo bomber squadron, and a dive bomber squadron. ref Joseph A.

ISBN 1 59807 139 4. pg. 97. ref Each carrier protein is designed to recognize only one substance or one group of very similar substances. Research has correlated defects in specific carrier proteins .... A carrier protein is required to move particles from areas of low concentration to areas of high concentration. These carrier proteins have receptors that bind to a specific molecule substrate needing transport. The molecule or ion to be transported the substrate must first bind at a binding site at the carrier ... is facing the same way, the carrier will capture or occlude take in and retain the Substrate biochemistry ....

Facilitated diffusion is used especially in the case ... that make up the bilayers. The type of carrier proteins used in facilitated diffusion is slightly different than in active transport. They are still transmembrane carrier proteins, but these are gated .... The substrate is taken in one side of the gated carrier, and without using ATP the substrate is released into the cell. Examples Each carrier protein, even within the same cell membrane, is specific to one type or family of molecules. For example, GLUT1 is a named carrier protein found in almost all animal cell membranes that transports glucose across the bilayer.
