The net result of the cycle is the conversion of penetrating UV-B light into heat, without any net loss of ozone. While keeping the ozone layer in stable balance, and protecting the lower atmosphere from harmful UV radiation, the cycle also provides one of two major heat sources in the stratosphere (the other being kinetic energy, released when ...
Cobweb model. The cobweb model or cobweb theory is an economic model that explains why prices may be subjected to periodic fluctuations in certain types of markets. It describes cyclical supply and demand in a market where the amount produced must be chosen before prices are observed.
Feed conversion ratio (FCR) is the ratio of inputs to outputs; it is the inverse of "feed efficiency" which is the ratio of outputs to inputs. [2] FCR is widely used in hog and poultry production, while FE is used more commonly with cattle. [2] Being a ratio the FCR is dimensionless, that is, it is not affected by the units of measurement used ...
Quaternary glaciation. Extent of maximum glaciation (in black) in the Northern Hemisphere during the Pleistocene. The formation of 3 to 4 km (1.9 to 2.5 mi) thick ice sheets equate to a global sea level drop of about 120 m (390 ft) The Quaternary glaciation, also known as the Pleistocene glaciation, is an alternating series of glacial and ...
Kitti's hog-nosed bat is the smallest species of bat and arguably the world's smallest mammal by body length (the Etruscan shrew is regarded as the smallest by body mass). It has a reddish-brown or grey coat, with a distinctive pig-like snout. Colonies range greatly in size, with an average of 100 individuals per cave.
Instructions per second. Instructions per second (IPS) is a measure of a computer 's processor speed. For complex instruction set computers (CISCs), different instructions take different amounts of time, so the value measured depends on the instruction mix; even for comparing processors in the same family the IPS measurement can be problematic.
The nuclear fuel cycle, also called nuclear fuel chain, is the progression of nuclear fuel through a series of differing stages. It consists of steps in the front end, which are the preparation of the fuel, steps in the service period in which the fuel is used during reactor operation, and steps in the back end, which are necessary to safely ...
Solaris is a proprietary Unix operating system originally developed by Sun Microsystems.After the Sun acquisition by Oracle in 2010, it was renamed Oracle Solaris. [3]Solaris superseded the company's earlier SunOS in 1993, and became known for its scalability, especially on SPARC systems, and for originating many innovative features such as DTrace, ZFS and Time Slider.
