Pork cycle. A schematic diagram of the pork cycle. In economics, the term pork cycle, hog cycle, or cattle cycle [1] describes the phenomenon of cyclical fluctuations of supply and prices in livestock markets. It was first observed in 1925 in pig markets in the US by Mordecai Ezekiel and in Europe in 1927 by the German scholar Arthur Hanau [ de].
The cobweb model has been interpreted as an explanation of fluctuations in various livestock markets, like those documented by Arthur Hanau in German hog markets; see Pork cycle. However, Rosen et al. (1994) proposed an alternative model which showed that because of the three-year life cycle of beef cattle, cattle populations would fluctuate ...
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 ...
Successor. Ford Cyclone engine. The Ford Cologne V6 is a series of 60° cast iron block V6 engines produced by the Ford Motor Company from 1962 to 2011 in displacements between 1.8 L; 110.6 cu in (1,812 cc) and 4.0 L; 244.6 cu in (4,009 cc). Originally, the Cologne V6 was installed in vehicles intended for Germany and Continental Europe, while ...
Swine influenza is an infection caused by any of several types of swine influenza viruses. Swine influenza virus (SIV) or swine-origin influenza virus (S-OIV) refers to any strain of the influenza family of viruses that is endemic in pigs. [2] As of 2009, identified SIV strains include influenza C and the subtypes of influenza A known as H1N1 ...
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.
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 ...
2-6-0. Under the Whyte notation for the classification of steam locomotives, 2-6-0 represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, six powered and coupled driving wheels on three axles and no trailing wheels. This arrangement is commonly called a Mogul. [ 1]
