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 ...

Currency In Ancient China
The history of Chinese currency spans more than 3000 years from ancient China to imperial China and modern China. Currency of some type has been used in China since the Neolithic age which can be traced back to between 3000 and 4500 years ago. The history of China's monetary system traces back to the Shang dynasty (c. 1766–1154 BCE), where cowrie shells served as early currency. Cowry shells are believed to have been the earliest form of currency used in Central China, and were used during the Neolithic period. By the Warring States period, diverse metal currencies like knife and spade coins emerged. These early currencies, starting as a commodity exchange to cowrie shells, copper coins, paper money and modern Chinese currencies and digital currencies shows how centralized power developed the most influential monetary system in the world. Early Establishment The Shang dynasty (c. 1600 – c. 1046 BC) came as a significant first step in the evolution of currency by int ...

Garden Fork
A garden fork, spading fork, or digging fork (in the past also an ''asparagus fork'', the same name as a very different utensil) is a gardening implement, with a handle and a square-shouldered head featuring several (usually four) short, sturdy tines. It is used for loosening, lifting and turning over soil in gardening and farming, and not to be confused with the pitchfork, a similar tined tool used for moving (or throwing) loose materials such as hay, straw, silage, and manure. Uses A garden fork is used similarly to a spade in loosening and turning over soil. Its tines allow it to be pushed more easily into the ground, and it can rake out stones and weeds and break up clods, it is not so easily stopped by stones, and it does not cut through weed roots or root-crops. Garden forks were originally made of wood, but the majority are now made of forged carbon steel or stainless steel. Types Reflecting their differing uses, garden forks have shorter, flatter, thicker, and more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latin
Latin ( or ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages. Latin was originally spoken by the Latins (Italic tribe), Latins in Latium (now known as Lazio), the lower Tiber area around Rome, Italy. Through the expansion of the Roman Republic, it became the dominant language in the Italian Peninsula and subsequently throughout the Roman Empire. It has greatly influenced many languages, Latin influence in English, including English, having contributed List of Latin words with English derivatives, many words to the English lexicon, particularly after the Christianity in Anglo-Saxon England, Christianization of the Anglo-Saxons and the Norman Conquest.

Ice Cream Cone
An ice cream cone (England) or poke (Ireland) is a brittle, cone-shaped pastry, usually made of a wafer similar in texture to a waffle, made so ice cream can be carried and eaten without a bowl or spoon. Many styles of cones are made, including pretzel cones, sugar-coated and chocolate-coated cones (coated on the inside). The term ''ice cream cone'' can also refer, informally, to the cone with one or more scoops of ice cream on top. There are two techniques for making cones: one is by baking them flat and then quickly rolling them into shape (before they harden), the other is by baking them inside a cone-shaped mold. History 19th century Cones, in the form of wafers rolled and baked hard, date back to Ancient Rome and Greece. When exactly they transitioned to being used for desserts, and ice cream in particular, is not clear. Some historians point to France in the early 19th century as the birthplace of the ice cream cone: an 1807 illustration of a Parisian girl enjoyin ...

Chemical Process
In a scientific sense, a chemical process is a method or means of somehow changing one or more chemicals or chemical compounds. Such a chemical process can occur by itself or be caused by an outside force, and involves a chemical reaction of some sort. In an "engineering" sense, a chemical process is a method intended to be used in manufacturing or on an industrial scale (see Industrial process) to change the composition of chemical(s) or material(s), usually using technology similar or related to that used in chemical plants or the chemical industry. Neither of these definitions are exact in the sense that one can always tell definitively what is a chemical process and what is not; they are practical definitions. There is also significant overlap in these two definition variations. Because of the inexactness of the definition, chemists and other scientists use the term "chemical process" only in a general sense or in the engineering sense. However, in the "process (engine ...

Oil Industry
The petroleum industry, also known as the oil industry, includes the global processes of exploration, extraction, refining, transportation (often by oil tankers and pipelines), and marketing of petroleum products. The largest volume products of the industry are fuel oil and gasoline (petrol). Petroleum is also the raw material for many chemical products, including pharmaceuticals, solvents, fertilizers, pesticides, synthetic fragrances, and plastics. The industry is usually divided into three major components: upstream, midstream, and downstream. Upstream regards exploration and extraction of crude oil, midstream encompasses transportation and storage of crude, and downstream concerns refining crude oil into various end products. Petroleum is vital to many industries, and is necessary for the maintenance of industrial civilization in its current configuration, making it a critical concern for many nations. Oil accounts for a large percentage of the world's energy consum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Qin Dynasty
The Qin dynasty ( ) was the first Dynasties of China, imperial dynasty of China. It is named for its progenitor state of Qin, a fief of the confederal Zhou dynasty (256 BC). Beginning in 230 BC, the Qin under King Ying Zheng engaged in a Qin's wars of unification, series of wars conquering each of the rival states that had previously pledged fealty to the Zhou. This culminated in 221 BC with the successful unification of China under Qin, which then assumed an imperial prerogativewith Ying Zheng declaring himself to be Qin Shi Huang, the first emperor of China, and bringing an end to the Warring States period (221 BC). This state of affairs lasted until 206 BC, when the dynasty collapsed in the years following Qin Shi Huang's death. The Qin dynasty's 14-year existence was the shortest of any major dynasty in Chinese history, with only two emperors. However, the succeeding Han dynasty (202 BC220 AD) largely continued the military and administ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drainage
Drainage is the natural or artificial removal of a surface's water and sub-surface water from an area with excess water. The internal drainage of most agricultural soils can prevent severe waterlogging (anaerobic conditions that harm root growth), but many soils need artificial drainage to improve production or to manage water supplies. History Early history The Indus Valley Civilization had sewerage and drainage systems. All houses in the major cities of Harappa and Mohenjo-daro had access to water and drainage facilities. Waste water was directed to covered gravity sewers, which lined the major streets. 18th and 19th century The invention of hollow-pipe drainage is credited to Sir Hugh Dalrymple, who died in 1753. Current practices Simple infrastructure such as open drains, pipes, and berms are still common. In modern times, more complex structures involving substantial earthworks and new technologies have been common as well. Geotextiles New storm water drainag ...
