Ploughs were traditionally drawn by oxen and horses but modern ploughs are drawn by tractors. A plough may have a wooden, iron or steel frame with a blade attached to cut and loosen the soil. It has been fundamental to farming for most of history. The earliest ploughs had no wheels; such a plough was known to the Ancient Rome, Romans as an ''aratrum''. Celts, Celtic peoples first came to use wheeled ploughs in the Roman era. The prime purpose of ploughing is to turn over the uppermost soil, bringing fresh Plant nutrients in soil, nutrients to the surface while burying weeds and crop remains to Decomposition, decay.

Internal Combustion Engine
An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons (reciprocating engine, piston engine), turbine blades (gas turbine), a Wankel engine, rotor (Wankel engine), or a propulsive nozzle, nozzle (jet engine). This force moves the component over a distance. This process transforms chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to. The first commercially successful internal combustion engines were invented in the mid-19th century. The first modern internal combustion engine, the Otto engine, was designed in 1876 by the German engineer Nicolaus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Swedish, like the other North Germanic languages, Nordic languages, is a descendant of Old Norse, the common language of the Germanic peoples living in Scandinavia during the Viking Age. It is largely mutually intelligible with Norwegian language, Norwegian and Danish language, Danish, although the degree of mutual intelligibility is dependent on the dialect and accent of the speaker. Standard Swedish, spoken by most Swedes, is the national language that evolved from the Central Swedish dialects in the 19th century, and was well established by the beginning of the 20th century.

Old Norse
Old Norse, also referred to as Old Nordic or Old Scandinavian, was a stage of development of North Germanic languages, North Germanic dialects before their final divergence into separate Nordic languages. Old Norse was spoken by inhabitants of Scandinavia and their Viking expansion, overseas settlements and chronologically coincides with the Viking Age, the Christianization of Scandinavia, and the consolidation of Scandinavian kingdoms from about the 8th to the 15th centuries. The Proto-Norse language developed into Old Norse by the 8th century, and Old Norse began to develop into the modern North Germanic languages in the mid- to late 14th century, ending the language phase known as Old Norse. These dates, however, are not precise, since written Old Norse is found well into the 15th century. Old Norse was divided into three dialects: Old West Norse (Old West Nordic, often referred to as ''Old Norse''), Old East Norse (Old East Nordic), and Old Gutnish. Old West Norse and O ...
