Threshing Machine
A threshing machine or a thresher is a piece of agricultural machinery, farm equipment that separates grain seed from the plant stem, stalks and husks. It does so by beating the plant to make the seeds fall out. Before such machines were developed, threshing was done by hand with Flail (tool), flails: such hand threshing was very laborious and time-consuming, taking about one-quarter of agricultural labour by the 18th century. Mechanization of this process removed a substantial amount of drudgery from farm labour. The first threshing machine was invented circa 1786 by the Scottish engineer Andrew Meikle, and the subsequent adoption of such machines was one of the earlier examples of the mechanised agriculture, mechanization of agriculture. During the 19th century, threshers and mechanical reapers and reaper-binders gradually became widespread and made grain production much less laborious. Separate reaper-binders and threshers have largely been replaced by machines that combine all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Threshing Machine In Action
Threshing or thrashing is the process of loosening the edible part of grain (or other crop) from the straw to which it is attached. It is the step in grain preparation after reaping. Threshing does not remove the bran from the grain. History of threshing Through much of the important history of agriculture, threshing was time-consuming and usually laborious, with a bushel of wheat taking about an hour. In the late 18th century, before threshing was mechanized, about one-quarter of agricultural labor was devoted to it. It is likely that in the earliest days of agriculture the little grain that was raised was shelled by hand, but as the quantity increased the grain was probably beaten out with a stick, or the sheaf beaten upon the ground. An improvement on this, as the quantity further increased, was the practice of the ancient Egyptians of spreading out the loosened sheaves on a circular enclosure of hard ground, and driving oxen, sheep or other animals round and round over it ...

Self-sufficiency
Self-sustainability and self-sufficiency are overlapping states of being in which a person, being, or system needs little or no help from, or interaction with others. Self-sufficiency entails the self being enough (to fulfill needs), and a self-sustaining entity can maintain self-sufficiency indefinitely. These states represent types of personal or collective autonomy. A self-sufficient economy is one that requires little or no trade with the outside world and is called an autarky. Description Self-sustainability is a type of sustainable living in which nothing is consumed other than what is produced by the self-sufficient individuals. Self-sustainability is a comprehensive approach to sustainable living that extends beyond mere environmental responsibility to encompass economic independence, reduced reliance on major corporations, and minimizing environmental impact through personal actions. Examples of attempts at self-sufficiency in North America include simple living, fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Penal Transportation
Penal transportation (or simply transportation) was the relocation of convicted criminals, or other persons regarded as undesirable, to a distant place, often a colony, for a specified term; later, specifically established penal colony, penal colonies became their destination. While the prisoners may have been released once the sentences were served, they generally did not have the resources to return home. Origin and implementation Banishment or forced exile from a polity or society has been used as a punishment since at least the 5th century BCE in Ostracism, Ancient Greece. The practice of penal transportation reached its height in the British Empire during the 18th and 19th centuries. Transportation removed the offender from society, mostly permanently, but was seen as more merciful than capital punishment. This method was used for criminals, debtors, military prisoners, and political prisoners. Penal transportation was also used as a method of colonization. For example, ...

Enclosure
Enclosure or inclosure is a term, used in English landownership, that refers to the appropriation of "waste" or "common land", enclosing it, and by doing so depriving commoners of their traditional rights of access and usage. Agreements to enclose land could be either through a formal or informal process. The process could normally be accomplished in three ways. First there was the creation of "closes", taken out of larger common fields by their owners. Secondly, there was enclosure by proprietors, owners who acted together, usually small farmers or squires, leading to the enclosure of whole parishes. Finally there were enclosures by acts of Parliament. The stated justification for enclosure was to improve the efficiency of agriculture. However, there were other motives too, one example being that the value of the land enclosed would be substantially increased. There were social consequences to the policy, with many protests at the removal of rights from the common people. Enc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Revolt
Rebellion is an uprising that resists and is organized against one's government. A rebel is a person who engages in a rebellion. A rebel group is a consciously coordinated group that seeks to gain political control over an entire state or a portion of a state. A rebellion is often caused by political, religious, or social grievances that originate from a perceived inequality or marginalization. ''Rebellion'' comes from Latin ''re'' and ''bellum'', and in Lockian philosophy refers to the responsibility of the people to overthrow unjust government. Classification Uprisings which revolt, resisting and taking direct action against an authority, law or policy, as well as organize, are rebellions. An insurrection is an uprising to change the government. If a government does not recognize rebels as belligerents, then they are insurgents and the revolt is an insurgency. In a larger conflict, the rebels may be recognized as belligerents without their government being recognize ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swing Riots
The Swing Riots were a widespread uprising in 1830 by agricultural workers in southern and eastern England in protest of agricultural mechanisation and harsh working conditions. The riots began with the destruction of threshing machines in the Elham Valley area of East Kent in the summer of 1830 and by early December had spread through the whole of southern England and East Anglia. It was to be the largest movement of social unrest in 19th-century England. As well as attacking the popularly-hated threshing machines, which displaced workers, the protesters rioted over low wages and required tithes by destroying workhouses and tithe barns associated with their oppression. They also burned ricks and maimed cows. The rioters directed their anger at the three targets identified as causing their misery: the tithe system, requiring payments to support the established Anglican Church; the Poor Law guardians, who were thought to abuse their power over the poor; and the rich tenant fa ...

Free Variation
In linguistics, free variation is the phenomenon of two (or more) sounds or forms appearing in the same environment without a change in meaning and without being considered incorrect by native speakers. Sociolinguists argue that describing such variation as "free" is very often a misnomer, since variation between linguistic forms is usually constrained probabilistically by a range of systematic social and linguistic factors, not unconstrained as the term "free variation" suggests. The term remains in use, however, in studies focused primarily on language as systems (e.g. phonology, morphology, syntax). Effects When phonemes are in free variation, speakers are sometimes strongly aware of the fact (especially if such variation is noticeable only across a dialectal or sociolectal divide), and will note, for example, that ''tomato'' is pronounced differently in British and American English ( and respectively), or that ''either'' has two pronunciations that are distributed fairly r ...

Word Sense
In linguistics, a word sense is one of the meanings of a word. For example, a dictionary may have over 50 different senses of the word "play", each of these having a different meaning based on the context of the word's usage in a sentence, as follows: In each sentence different collocates of "play" signal its different meanings. People and computers, as they read words, must use a process called word-sense disambiguationR. Navigli''Word Sense Disambiguation: A Survey'' ACM Computing Surveys, 41(2), 2009, pp. 1-69. to reconstruct the likely intended meaning of a word. This process uses context to narrow the possible senses down to the probable ones. The context includes such things as the ideas conveyed by adjacent words and nearby phrases, the known or probable purpose and register of the conversation or document, and the orientation (time and place) implied or expressed. The disambiguation is thus context-sensitive. Advanced semantic analysis has resulted in a sub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synonym
A synonym is a word, morpheme, or phrase that means precisely or nearly the same as another word, morpheme, or phrase in a given language. For example, in the English language, the words ''begin'', ''start'', ''commence'', and ''initiate'' are all synonyms of one another: they are ''synonymous''. The standard test for synonymy is substitution: one form can be replaced by another in a sentence without changing its meaning. Words may often be synonymous in only one particular sense: for example, ''long'' and ''extended'' in the context ''long time'' or ''extended time'' are synonymous, but ''long'' cannot be used in the phrase ''extended family''. Synonyms with exactly the same meaning share a seme or denotational sememe, whereas those with inexactly similar meanings share a broader denotational or connotational sememe and thus overlap within a semantic field. The former are sometimes called cognitive synonyms and the latter, near-synonyms, plesionyms or poecilonyms. Lexic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
