English Leicester (sheep)
The Leicester Longwool is an English breed of sheep. Alternative names for the breed include: Leicester, Bakewell Leicester, Dishley Leicester, English Leicester, Improved Leicester and New Leicester. It was originally developed by 18th-century breeding innovator Robert Bakewell. It is now one of Britain's rarest breeds, categorised as "endangered" by the Rare Breeds Survival Trust, since fewer than 500 registered breeding females remain in the United Kingdom. History Leicester Longwool sheep date back to the 1700s, and were found in the Midland counties of England, originally developed in Dishley Grange, Leicestershire by Robert Bakewell. Bakewell was the foremost exponent of modern animal-breeding techniques in the selection of livestock. The Leicester Longwool in the 1700s was slow-growing and coarsely boned. They now have been developed to gain weight quickly and are fast-growing. Leicester Longwool was one of the first pure sheep breeds introduced to Australia, having ...

Staple (textiles)
A staple fiber is a textile fiber of discrete length. The opposite is a filament fiber, which comes in continuous lengths. Staple length is a characteristic fiber length of a sample of staple fibers. It is an essential criterion in yarn spinning aids in cohesion and twisting. Compared to synthetic fibers, natural fibers tend to have different and shorter lengths. The quality of natural fibers like cotton is categorized on staple length such as short, medium, long-staple and, extra long. Gossypium barbadense, one of several cotton species, produces extra-long staple fibers. The staple fibers may be obtained from natural and synthetic sources. In the case of synthetics and blends, the filament yarns are cut to a predetermined length (staple length). ''The filament is <1 mm in maximum cross section (i.e., diameter, in most cases). A filament can be compared ... Manufactured fibers are produced either as continuous infinite length filaments or cut staple of desired length value.

Border Leicester Sheep
The Border Leicester is a British breed of sheep. It is a polled, long-wool sheep and is considered a dual-purpose breed as it is reared both for meat and for wool. The sheep are large but docile. They have been exported to other sheep-producing regions, including Australia and the United States. Description The live weight of a mature Border Leicester ram is in the range of and a mature ewe . A yearling ewe is around . Their white wool tends to be very long and by Merino standards, broad crimped, and in fineness about 32 to 38 microns, and is used for medium- to heavy-weight garments. This wool, though, is prized by spinners because of the crimp and lustre. The sheep are normally shorn twice a year when the wool has reached a length of around . Lambs yield an average of of wool; yearlings may yield at each shearing. The United States, Australian and New Zealand Border Leicesters very rarely sport the extreme of British flocks. All strains of Border Leicesters are known fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temperament
In psychology, temperament broadly refers to consistent individual differences in behavior that are biologically based and are relatively independent of learning, system of values and attitudes. Some researchers point to association of temperament with formal dynamical features of behavior, such as energetic aspects, plasticity, sensitivity to specific reinforcers and emotionality. Temperament traits (such as Neuroticism, Sociability, Impulsivity, etc.) are distinct patterns in behavior throughout a lifetime, but they are most noticeable and most studied in children. Babies are typically described by temperament, but longitudinal research in the 1920s began to establish temperament as something which is stable across the lifespan. Definition Temperament has been defined as "the constellation of inborn traits that determine a child's unique behavioral style and the way he or she experiences and reacts to the world." Classification schemes Many classification schemes for tempera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Constitution
A constitution is the aggregate of fundamental principles or established precedents that constitute the legal basis of a polity, organisation or other type of Legal entity, entity and commonly determine how that entity is to be governed. When these principles are written down into a single document or set of legal documents, those documents may be said to embody a ''written constitution''; if they are encompassed in a single comprehensive document, it is said to embody a ''codified constitution''. The Constitution of the United Kingdom is a notable example of an ''uncodified constitution''; it is instead written in numerous fundamental Acts of a legislature, court cases or treaties. Constitutions concern different levels of organizations, from Sovereign state, sovereign countries to Company, companies and unincorporated Club (organization), associations. A treaty which establishes an international organization is also its constitution, in that it would define how that organiza ...

Marginal Land
Marginal land is land that is of little agricultural or developmental value because crops produced from the area would be worth less than any rent paid for access to the area. Although the term ''marginal'' is often used in a subjective sense for less-than-ideal lands, it is fundamentally an economic term that is defined by the local economic context. Thus what constitutes marginal land varies both with location and over time: for example, "a soil profile with a set of specific biophysical characteristics reported as “marginal” in the US corn belt may be one of the better soils available in another context". Changes in product values – such as the ethanol-demand induced spike in corn prices – can result in formerly marginal lands becoming profitable. Marginal lands can therefore be more difficult to delineate as compared to "abandoned crop lands" which reflect more clearly definable landowner-initiated land use changes. Land may be marginal for a number of reasons, includin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

Robustness (evolution)
In evolutionary biology, robustness of a biological system (also called biological or genetic robustness) is the persistence of a certain characteristic or trait in a system under perturbations or conditions of uncertainty. Robustness in development is known as canalization. According to the kind of perturbation involved, robustness can be classified as mutational, environmental, recombinational, or behavioral robustness ''etc''. Robustness is achieved through the combination of many genetic and molecular mechanisms and can evolve by either direct or indirect selection. Several model systems have been developed to experimentally study robustness and its evolutionary consequences. Classification Mutational robustness Mutational robustness (also called mutation tolerance) describes the extent to which an organism’s phenotype remains constant in spite of mutation. Robustness can be empirically measured for several genomes and individual genes by inducing mutations and measu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
