žagrė
In Eastern Europe a sokha (; ) is a light wooden ard, consisting of two body ards, with their parallel beams forming the two shafts for a single horse-drawn tillage implement with two socket shares (рассоха). In later types the double body is combined into one wooden board. Chronicles and other literary sources show that the sokha was in use in Russia at least since the 13th century. It originated from northern Russia, e.g., around Novgorod.http://www.kroka.ru/html/s/soha.html The sokha adapts the body ard to a single-animal harness following the pattern of a shaft-drawn cart and adds a spade-like component that turned over the soil. (On ploughs the curved mouldboard both cuts and turns the soil.) Other design features can vary depending on local building custom.

Science And Technology In Russia
Science and technology in Russia have developed rapidly since the Age of Enlightenment, when Peter the Great founded the Russian Academy of Sciences and Saint Petersburg State University and polymath Mikhail Lomonosov founded the Moscow State University, establishing a strong native tradition in learning and innovation. In the 19th and 20th centuries, Russia produced many notable List of Russian scientists, scientists, making important contributions in physics, astronomy, mathematics, computer sciences, computing, chemistry, biology, geology and geography. Russian inventors and engineers excelled in such areas as electrical engineering, shipbuilding, aerospace, weaponry, communications, Information technology, IT, nuclear technology and space technology. The crisis of the 1990s led to the drastic reduction of state support for science and technology, leading many Russian scientists and university graduates to move to Western Europe or the United States. In the 2000s, on the wave o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gardening Tools
Gardening is the process of growing plants for their vegetables, fruits, flowers, herbs, and appearances within a designated space. Gardens fulfill a wide assortment of purposes, notably the production of aesthetically pleasing areas, medicines, cosmetics, dyes, foods, poisons, wildlife habitats, and saleable goods (see market gardening). People often partake in gardening for its therapeutic, health, educational, cultural, philosophical, environmental, and religious benefits. Gardening varies in scale from the 800 hectare Versailles gardens down to container gardens grown inside. Gardens take many forms; some only contain one type of plant, while others involve a complex assortment of plants with no particular order. Gardening can be difficult to differentiate from farming. They are most easily differentiated based on their primary objectives. Farming prioritizes saleable goods and may include livestock production, whereas gardening often prioritizes aesthetics and lei ...

Animal Equipment
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia (). With few exceptions, animals consume organic material, breathe oxygen, have myocytes and are able to move, can reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development. Animals form a clade, meaning that they arose from a single common ancestor. Over 1.5 million living animal species have been described, of which around 1.05 million are insects, over 85,000 are molluscs, and around 65,000 are vertebrates. It has been estimated there are as many as 7.77 million animal species on Earth. Animal body lengths range from to . They have complex ecologies and interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology, and the study of animal behaviour is known as ethology. The animal kingdom is divided into five major clades, namely Porifera, Ctenophora, Plac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agricultural Machinery
Agricultural machinery relates to the machine (mechanical), mechanical structures and devices used in farming or other agriculture. There are list of agricultural machinery, many types of such equipment, from hand tools and power tools to tractors and the farm implements that they tow or operate. Machinery is used in both organic farming, organic and nonorganic farming. Especially since the advent of mechanised agriculture, agricultural machinery is an indispensable part of how the world is fed. Agricultural machinery can be regarded as part of wider agricultural automation technologies, which includes the more advanced digital equipment and agricultural robotics. While robots have the potential to automate the three key steps involved in any agricultural operation (diagnosis, decision-making and performing), conventional motorized machinery is used principally to automate only the performing step where diagnosis and decision-making are conducted by humans based on observations an ...

Mouldboard
A plough or ( US) plow (both pronounced ) is a farm tool for loosening or turning the soil before sowing seed or planting. 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 Romans as an ''aratrum''. 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 nutrients to the surface while burying weeds and crop remains to decay. Trenches cut by the plough are called furrows. In modern use, a ploughed field is normally left to dry and then harrowed before planting. Ploughing and cultivating soil evens the content of the upper layer of soil, where most plant feeder roots grow. Ploughs were initially powered by humans, but the us ...

George Vernadsky
George Vernadsky (; August 20, 1887 – June 12, 1973) was a Russian-born American historian and an author of numerous books on Russian history. European years Born in Saint Petersburg on August 20, 1887, Vernadsky stemmed from a respectable family of the Russian intelligentsia. His father was Vladimir Vernadsky, a famous Russian/Ukrainian geologist. He entered the Moscow University (where his father was professor) in 1905 but, due to the disturbances of the First Russian Revolution, had to spend the next two years in Germany, at the Albert Ludwigs University of Freiburg and the University of Berlin, where he imbibed the doctrines of Heinrich Rickert. Back in Russia, Vernadsky resumed his course at the Moscow University, graduating with honors in 1910. His instructors included the historians Vasily Klyuchevsky and Robert Vipper. The young scholar declined to continue his career in the university after the 1910 Kasso affair and moved to Saint Petersburg University, where ...

Spade
A spade is a tool primarily for digging consisting of a long handle and blade, typically with the blade narrower and flatter than the common shovel. Early spades were made of riven wood or of animal bones (often shoulder blades). After the art of metalworking was developed, spades were made with sharper tips of metal. Before the introduction of metal spades manual labor was less efficient at moving earth, with picks being required to break up the soil in addition to a spade for moving the dirt. With a metal tip, a spade can both break and move the earth in most situations, increasing efficiency. A classic spade, with a narrow body and flat (or near flat) tip is suited for digging post holes, and is not to be confused with a "roundpoint" shovel, which has a wider body and tapered tip. Etymology English ''spade'' is from Old English ' (f.) or ' (m.). The same word is found in Old Frisian ' and Old Saxon '. High German ' only appears in Early Modern German, probably loaned from ...
