The thorium fuel cycle is a nuclear fuel cycle that uses an isotope of thorium, 232. Th. , as the fertile material. In the reactor, 232. Th. is transmuted into the fissile artificial uranium isotope 233. U. which is the nuclear fuel. Unlike natural uranium, natural thorium contains only trace amounts of fissile material (such as 231.
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 ...

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.
The Airbus A350 is a long-range, wide-body twin-engine airliner developed and produced by Airbus.The initial A350 design proposed in 2004, in response to the Boeing 787 Dreamliner, would have been a development of the Airbus A330 with composite wings and new engines.

Overview. The first locomotives of the 2-6-6-2 wheel arrangement were built in 1906 by the Great Northern Railway to permit longer trains on their heavily graded line over the Cascade Mountains. [5] They were a refinement of the first North American Mallets, 0-6-6-0 engines built for the Baltimore & Ohio in 1904, with leading and trailing ...
