Spade In America
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 loane ...

Spatha
The spatha was a type of straight and long sword, measuring between 0.5 and 1 m (19.7 and 39.4 in), with a handle length of between 18 and 20 cm (7.1 and 7.9 in), in use in the territory of the Roman Empire during the 1st to 6th centuries AD. Later swords, from the 7th to 10th centuries, like the Viking swords, are recognizable derivatives and sometimes subsumed under the term ''spatha''. The Roman ''spatha'' was used in war and in gladiatorial fights. The ''spatha'' of literature appears in the Roman Empire in the 1st century AD as a weapon used by presumably Celtic auxiliaries and gradually became a standard heavy infantry weapon, relegating the ''gladius'' to use as a light infantry weapon. The ''spatha'' apparently replaced the ''gladius'' in the front ranks, giving the infantry more reach when thrusting. While the infantry version had a long point, versions carried by the cavalry had a rounded tip that prevented accidental stabbing of the cavalryman's own foot or horse. ...

Entrenching Tool
An entrenching tool (U.K.), intrenching tool (U.S.), E-tool, or trenching tool is a digging tool used by military forces for a variety of military purposes. Survivalists, campers, hikers and other outdoors groups have found it to be indispensable in field use. Modern entrenching tools are usually collapsible and made using steel, aluminum, or other light metals. History and development Entrenching tools go back at least to the times of the Roman Legion who used a type of mattock known as a Dolabra. Julius Caesar, as well as other ancient writers, documented the use of spades and other digging implements as important tools of war. The Roman Legion when on the march would dig a ditch and rampart fortified with mobile stakes around their camps every night where established camps were not available. Siege tactics throughout history required the digging of fortifications and often mining of walls was attempted, where saps were dug to a wall’s foundation, and collapsing the wal ...

Tree Spade
A tree spade is a specialized machine that mechanizes the transplanting of large plants whose hand-powered transplanting (using traditional spades, wagons, and other equipment) would be prohibitively laborious. These include large bushes and small or medium trees. By bringing mechanized power to what was formerly only a manual process, tree spades do for transplanting what tractors and combine harvesters do for agriculture, and what excavators and other heavy equipment do for construction. Today, tree spades are widely used in the tree nursery industry to increase production rates, and in the landscaping industry for tree removal and transplanting. A typical machine consists of a number of blades (generally 3 or 4, but single or dual blade designs also exist) that encircle the tree, digging into the ground and then lifting the entire tree, including its roots and soil (in what is termed a "root ball"), out of the ground and replanting or transplanting the whole tree in the desig ...

Ice Cream Cone
An ice cream cone, poke (Ireland/Scotland) or cornet (England) 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, for example, the Hong Kong-style bubble cone. Many styles of cones are made, including pretzel cones 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 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 180 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 (engineer ...

Oil Industry
The petroleum industry, also known as the oil industry or the oil patch, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Qin Dynasty
The Qin dynasty ( ; zh, c=秦朝, p=Qín cháo, w=), or Ch'in dynasty in Wade–Giles romanization ( zh, c=, p=, w=Ch'in ch'ao), was the first Dynasties in Chinese history, dynasty of Imperial China. Named for its heartland in Qin (state), Qin state (modern Gansu and Shaanxi), the Qin dynasty arose as a fief of the Western Zhou and endured for over five centuries until 221 BCE when it founded its brief empire, which lasted only until 206 BCE. It often causes confusion that the ruling family of the Qin kingdom (what is conventionally called a "dynasty") ruled for over five centuries, while the "Qin Dynasty," the conventional name for the first Chinese empire, comprises the last fourteen years of Qin's existence. The divide between these two periods occurred in 221 BCE when King Zheng of Qin declared himself the Qin Shi Huang, First Emperor of Qin, though he had already been king of Qin since 246 BCE. Qin was a minor power for the early centuries of its existence. The streng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Currency In Ancient China
The history of Chinese currency spans more than 3000 years. 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. Cowry shells are believed to have been the earliest form of currency used in Central China, and were used during the Neolithic period. Around 210 BC, the first emperor of China Qin Shi Huang (260–210 BC) abolished all other forms of local currency and introduced a uniform copper coin. Paper money was invented in China in the 9th century, but the base unit of currency remained the copper coin. Copper coins were used as the chief denomination of currency in China until the introduction of the yuan. Currently, the ''renminbi'' is the official currency of the People's Republic of China (PRC). It is the legal tender in mainland China, but not in Hong Kong or Macau. The special administrative regions of Hong Kong and Macau use the Hong Kong dollar and the Macanese pataca, respectiv ...

Drainage
Drainage is the natural or artificial removal of a surface's water and sub-surface water from an area with excess of water. The internal drainage of most agricultural soils is good enough to 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 Geotextiles New storm water drainage systems incorporate geotextile filters that retain and prevent fine grains of soil from passing into and clogging the drain. Geotextiles are synthetic textile fabrics specially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ireland
Ireland ( ; ga, Éire ; Ulster Scots dialect, Ulster-Scots: ) is an island in the Atlantic Ocean, North Atlantic Ocean, in Northwestern Europe, north-western Europe. It is separated from Great Britain to its east by the North Channel (Great Britain and Ireland), North Channel, the Irish Sea, and St George's Channel. Ireland is the List of islands of the British Isles, second-largest island of the British Isles, the List of European islands by area, third-largest in Europe, and the List of islands by area, twentieth-largest on Earth. Geopolitically, Ireland is divided between the Republic of Ireland (officially Names of the Irish state, named Ireland), which covers five-sixths of the island, and Northern Ireland, which is part of the United Kingdom. As of 2022, the Irish population analysis, population of the entire island is just over 7 million, with 5.1 million living in the Republic of Ireland and 1.9 million in Northern Ireland, ranking it the List of European islan ...
