Agriculture is the science and art of cultivating plants and livestock. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities; the history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Pigs and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture into the twenty-first. Modern agronomy, plant breeding, agrochemicals such as pesticides and fertilizers, technological developments have increased yields, while causing widespread ecological and environmental damage. Selective breeding and modern practices in animal husbandry have increased the output of meat, but have raised concerns about animal welfare and environmental damage.
Environmental issues include contributions to global warming, depletion of aquifers, antibiotic resistance, growth hormones in industrial meat production. Genetically modified organisms are used, although some are banned in certain countries; the major agricultural products can be broadly grouped into foods, fibers and raw materials. Food classes include cereals, fruits, meat, milk and eggs. Over one-third of the world's workers are employed in agriculture, second only to the service sector, although the number of agricultural workers in developed countries has decreased over the centuries; the word agriculture is a late Middle English adaptation of Latin agricultūra, from ager, "field", which in its turn came from Greek αγρός, cultūra, "cultivation" or "growing". While agriculture refers to human activities, certain species of ant and ambrosia beetle cultivate crops. Agriculture is defined with varying scopes, in its broadest sense using natural resources to "produce commodities which maintain life, including food, forest products, horticultural crops, their related services".
Thus defined, it includes arable farming, animal husbandry and forestry, but horticulture and forestry are in practice excluded. The development of agriculture enabled the human population to grow many times larger than could be sustained by hunting and gathering. Agriculture began independently in different parts of the globe, included a diverse range of taxa, in at least 11 separate centres of origin. Wild grains were eaten from at least 105,000 years ago. From around 11,500 years ago, the eight Neolithic founder crops and einkorn wheat, hulled barley, lentils, bitter vetch, chick peas and flax were cultivated in the Levant. Rice was domesticated in China between 11,500 and 6,200 BC with the earliest known cultivation from 5,700 BC, followed by mung and azuki beans. Sheep were domesticated in Mesopotamia between 11,000 years ago. Cattle were domesticated from the wild aurochs in the areas of modern Turkey and Pakistan some 10,500 years ago. Pig production emerged in Eurasia, including Europe, East Asia and Southwest Asia, where wild boar were first domesticated about 10,500 years ago.
In the Andes of South America, the potato was domesticated between 10,000 and 7,000 years ago, along with beans, llamas and guinea pigs. Sugarcane and some root vegetables were domesticated in New Guinea around 9,000 years ago. Sorghum was domesticated in the Sahel region of Africa by 7,000 years ago. Cotton was domesticated in Peru by 5,600 years ago, was independently domesticated in Eurasia. In Mesoamerica, wild teosinte was bred into maize by 6,000 years ago. Scholars have offered multiple hypotheses to explain the historical origins of agriculture. Studies of the transition from hunter-gatherer to agricultural societies indicate an initial period of intensification and increasing sedentism. Wild stands, harvested started to be planted, came to be domesticated. In Eurasia, the Sumerians started to live in villages from about 8,000 BC, relying on the Tigris and Euphrates rivers and a canal system for irrigation. Ploughs appear in pictographs around 3,000 BC. Farmers grew wheat, vegetables such as lentils and onions, fruits including dates and figs.
Ancient Egyptian agriculture relied on its seasonal flooding. Farming started in the predynastic period at the end of the Paleolithic, after 10,000 BC. Staple food crops were grains such as wheat and barley, alongside industrial crops such as flax and papyrus. In India, wheat and jujube were domesticated by 9,000 BC, soon followed by sheep and goats. Cattle and goats were domesticated in Mehrgarh culture by 8,000–6,000 BC. Cotton was cultivated by the 5th-4th millennium BC. Archeological evidence indicates an animal-drawn plough from 2,500 BC in the Indus Valley Civilisation. In China, from the 5th century BC there was a nationwide granary system and widespread silk farming. Water-powered grain mills were in use followed by irrigation. By the late 2nd century, heavy ploughs had been developed with iron mouldboards; these spread westwards across Eurasia. Asian rice was domesticated 8,200–13,500 years ago – depending on the molecular clock estimate, used – on the Pearl River in southern China with a single genetic origin from the wild rice Oryza rufipogon
The Wehrmacht was the unified armed forces of Nazi Germany from 1935 to 1945. It consisted of the Kriegsmarine and the Luftwaffe; the designation "Wehrmacht" replaced the used term Reichswehr, was the manifestation of the Nazi regime's efforts to rearm Germany to a greater extent than the Treaty of Versailles permitted. After the Nazi rise to power in 1933, one of Adolf Hitler's most overt and audacious moves was to establish the Wehrmacht, a modern offensively-capable armed force, fulfilling the Nazi regime's long-term goals of regaining lost territory as well as gaining new territory and dominating its neighbors; this required the reinstatement of conscription, massive investment and defense spending on the arms industry. The Wehrmacht formed the heart of Germany's politico-military power. In the early part of the Second World War, the Wehrmacht employed combined arms tactics to devastating effect in what became known as a Blitzkrieg, its campaigns in France, the Soviet Union, North Africa are regarded as acts of boldness.
At the same time, the far-flung advances strained the Wehrmacht's capacity to the breaking point, culminating in the first major defeat in the Battle of Moscow. The operational art was no match to the war-making abilities of the Allied coalition, making the Wehrmacht's weaknesses in strategy and logistics apparent. Cooperating with the SS and the Einsatzgruppen, the German armed forces committed numerous war crimes and atrocities, despite denials and promotion of the myth of the Clean Wehrmacht; the majority of the war crimes were committed in the Soviet Union, Yugoslavia and Italy, as part of the war of annihilation against the Soviet Union, the Holocaust and Nazi security warfare. During the war about 18 million men served in the Wehrmacht. By the time the war ended in Europe in May 1945, German forces had lost 11,300,000 men, about half of whom were missing or killed during the war. Only a few of the Wehrmacht's upper leadership were tried for war crimes, despite evidence suggesting that more were involved in illegal actions.
The majority of the three million Wehrmacht soldiers who invaded the USSR participated in committing war crimes. The German term "Wehrmacht" stems from the compound word of German: wehren, "to defend" and Macht, "power, force", it has been used to describes any nation's armed forces. The Frankfurt Constitution of 1849 designated all German military forces as the "German Wehrmacht", consisting of the Seemacht and the Landmacht. In 1919, the term Wehrmacht appears in Article 47 of the Weimar Constitution, establishing that: "The Reich's President holds supreme command of all armed forces of the Reich". From 1919, Germany's national defense force was known as the Reichswehr, a name, dropped in favor of Wehrmacht on 21 May 1935. In January 1919, after World War I ended with the signing of the armistice of 11 November 1918, the armed forces were dubbed Friedensheer. In March 1919, the national assembly passed a law founding a 420,000-strong preliminary army, the Vorläufige Reichswehr; the terms of the Treaty of Versailles were announced in May, in June, Germany signed the treaty that, among other terms, imposed severe constraints on the size of Germany's armed forces.
The army was limited to one hundred thousand men with an additional fifteen thousand in the navy. The fleet was to consist of at most six battleships, six cruisers, twelve destroyers. Submarines and heavy artillery were forbidden and the air-force was dissolved. A new post-war military, the Reichswehr, was established on 23 March 1921. General conscription was abolished under another mandate of the Versailles treaty; the Reichswehr was limited to 115,000 men, thus the armed forces, under the leadership of Hans von Seeckt, retained only the most capable officers. The American historians Alan Millet and Williamson Murray wrote "In reducing the officers corps, Seeckt chose the new leadership from the best men of the general staff with ruthless disregard for other constituencies, such as war heroes and the nobility". Seeckt's determination that the Reichswehr be an elite cadre force that would serve as the nucleus of an expanded military when the chance for restoring conscription came led to the creation of a new army, based upon, but different from, the army that existed in World War I.
In the 1920s, Seeckt and his officers developed new doctrines that emphasized speed, combined arms and initiative on the part of lower officers to take advantage of momentary opportunities. Though Seeckt retired in 1926, the army that went to war in 1939 was his creation. Germany was forbidden to have an air force by the Versailles treaty; these officers saw the role of an air force as winning air superiority and strategic bombing and providing ground support. That the Luftwaffe did not develop a strategic bombing force in the 1930s was not due to a lack of interest, but because of economic limitations; the leadership of the Navy led by Grand Admiral Erich Raeder, a close protégé of Alfred von Tirpitz, was dedicated to the idea of reviving Tirpitz's High Seas Fleet. Officers who believed in submarine warfare led by Admiral Karl Dönitz were in a minority before 1939. By 1922
A shell is a payload-carrying projectile that, as opposed to shot, contains an explosive or other filling, though modern usage sometimes includes large solid projectiles properly termed shot. Solid shot may contain a pyrotechnic compound if a spotting charge is used, it was called a "bombshell", but "shell" has come to be unambiguous in a military context. All explosive- and incendiary-filled projectiles for mortars, were called grenades, derived from the pomegranate, so called because the many-seeded fruit suggested the powder-filled, fragmenting bomb, or from the similarity of shape. Words cognate with grenade are still used for an artillery or mortar projectile in some European languages. Shells are large-caliber projectiles fired by artillery, combat vehicles, warships. Shells have the shape of a cylinder topped by an ogive-shaped nose for good aerodynamic performance with a tapering base, but some specialized types are quite different. Solid cannonballs did not need a fuse, but hollow munitions filled with something such as gunpowder to fragment the ball, needed a fuse, either impact or time.
Percussion fuses with a spherical projectile presented a challenge because there was no way of ensuring that the impact mechanism contacted the target. Therefore, shells needed a time fuse, ignited before or during firing and burned until the shell reached its target; the earliest record of shells being used in combat was by the Republic of Venice at Jadra in 1376. Shells with fuses were used at the 1421 siege of St Boniface in Corsica; these were two hollowed hemispheres of bronze held together by an iron hoop. Written evidence for early explosive shells in China appears in the early Ming Dynasty Chinese military manual Huolongjing, compiled by Jiao Yu and Liu Bowen sometime before the latter's death, a preface added by Jiao in 1412; as described in their book, these hollow, gunpowder-packed shells were made of cast iron. At least since the 16th century grenades made of ceramics or glass were in use in Central Europe. A hoard of several hundred ceramic grenades were discovered during building works in front of a bastion of the Bavarian city of Ingolstadt, Germany dated to the 17th century.
Lots of the grenades igniters. Most the grenades were intentionally dumped in the moat of the bastion before the year 1723. An early problem was that there was no means of measuring the time to detonation — reliable fuses did not yet exist and the burning time of the powder fuse was subject to considerable trial and error. Early powder burning fuses had to be loaded fuse down to be ignited by firing or a portfire put down the barrel to light the fuse. Other shells were wrapped in bitumen cloth, which would ignite during the firing and in turn ignite a powder fuse. Shells came into regular use in the 16th century, for example a 1543 English mortar shell was filled with'wildfire'. By the 18th century, it was known that the fuse toward the muzzle could be lit by the flash through the windage between the shell and the barrel. At about this time, shells began to be employed for horizontal fire from howitzers with a small propelling charge and, in 1779, experiments demonstrated that they could be used from guns with heavier charges.
The use of exploding shells from field artillery became commonplace from early in the 19th century. Until the mid 19th century, shells remained as simple exploding spheres that used gunpowder, set off by a slow burning fuse, they were made of cast iron, but bronze, lead and glass shell casings were experimented with. The word bomb encompassed them at the time, as heard in the lyrics of The Star-Spangled Banner, although today that sense of bomb is obsolete; the thickness of the metal body was about a sixth of their diameter and they were about two thirds the weight of solid shot of the same caliber. To ensure that shells were loaded with their fuses toward the muzzle, they were attached to wooden bottoms called sabots. In 1819, a committee of British artillery officers recognized that they were essential stores and in 1830 Britain standardized sabot thickness as a half inch; the sabot was intended to reduce jamming during loading. Despite the use of exploding shell, the use of smoothbore cannons firing spherical projectiles of shot remained the dominant artillery method until the 1850s.
The mid 19th century saw a revolution in artillery, with the introduction of the first practical rifled breech loading weapons. The new methods resulted in the reshaping of the spherical shell into its modern recognizable cylindro-conoidal form; this shape improved the in-flight stability of the projectile and meant that the primitive time fuzes could be replaced with the percussion fuze situated in the nose of the shell. The new shape meant that further, armor-piercing designs could be used. During the 20th Century, shells became streamlined. In World War I, ogives were two circular radius head - the curve was a segment of a circle having a radius of twice the shell caliber. After that war, ogive shapes became more elongated. From the 1960s, higher quality steels were introduced by some countries for their HE shells, this enabled thinner shell walls with less weight of metal and hence a greater weight of explosive. Ogives were further elongated to improve their ballistic performance. Advances in metallurgy in the industrial era allowed for the construction of rifled breech-loading guns that could fire at a much greater muzzle velocity.
After the British artillery was shown up in the Cri
The Black Sea is a body of water and marginal sea of the Atlantic Ocean between the Balkans, Eastern Europe, the Caucasus, Western Asia. It is supplied by a number of major rivers, such as the Danube, Southern Bug, Dniester and the Rioni. Many countries drain into the Black Sea, including Austria, Belarus and Herzegovina, Croatia, Czech Republic, Germany, Moldova, Romania, Serbia, Slovenia and Ukraine; the Black Sea has an area of 436,400 km2, a maximum depth of 2,212 m, a volume of 547,000 km3. It is constrained by the Pontic Mountains to the south, Caucasus Mountains to the east, Crimean Mountains to the north, Strandzha to the southwest, Dobrogea Plateau to the northwest, features a wide shelf to the northwest; the longest east–west extent is about 1,175 km. Important cities along the coast include Batumi, Constanța, Istanbul, Novorossiysk, Ordu, Rize, Sevastopol, Sukhumi, Varna and Zonguldak; the Black Sea has a positive water balance. There is a two-way hydrological exchange: the more saline and therefore denser, but warmer, Mediterranean water flows into the Black Sea under its less saline outflow.
This creates a significant anoxic layer well below the surface waters. The Black Sea drains into the Mediterranean Sea, via the Aegean Sea and various straits, is navigable to the Atlantic Ocean; the Bosphorus Strait connects it to the Sea of Marmara, the Strait of the Dardanelles connects that sea to the Aegean Sea region of the Mediterranean. These waters separate the Caucasus and Western Asia; the Black Sea is connected, to the North, to the Sea of Azov by the Strait of Kerch. The water level has varied significantly. Due to these variations in the water level in the basin, the surrounding shelf and associated aprons have sometimes been land. At certain critical water levels it is possible for connections with surrounding water bodies to become established, it is through the most active of these connective routes, the Turkish Straits, that the Black Sea joins the world ocean. When this hydrological link is not present, the Black Sea is an endorheic basin, operating independently of the global ocean system, like the Caspian Sea for example.
The Black Sea water level is high. The Turkish Straits connect the Black Sea with the Aegean Sea, comprise the Bosphorus, the Sea of Marmara and the Dardanelles; the International Hydrographic Organization defines the limits of the Black Sea as follows: On the Southwest. The Northeastern limit of the Sea of Marmara. In the Kertch Strait. A line joining Cape Takil and Cape Panaghia. Current names of the sea are equivalents of the English name "Black Sea", including these given in the countries bordering the sea: Abkhazian: Амшын Еиқәа, IPA: Adyghe: Хы шӏуцӏэ, IPA: Bulgarian: Черно море, IPA: Crimean Tatar: Къара денъиз, Qara deñiz IPA: Georgian: შავი ზღვა, translit.: shavi zghva, IPA: Laz and Mingrelian: უჩა ზუღა, IPA:, or ზუღა, IPA:, "Sea" Romanian: Marea Neagră, pronounced Russian: Чёрное мо́рe, IPA: Turkish: Karadeniz, IPA: Ukrainian: Чорне море, IPA: Such names have not yet been shown conclusively to predate the 13th century, but there are indications that they may be older. In Greece, the historical name "Euxine Sea", which holds a different meaning, is still used: Greek: Éfxeinos Póntos.
The principal Greek name "Póntos Áxeinos" is accepted to be a rendering of Iranian word *axšaina-, compare Avestan axšaēna-, Old Persian axšaina-, Middle Persian axšēn/xašēn, New Persian xašīn, as well as Ossetic œxsīn. The ancient Greeks, most those living to the north of the Black Sea, subsequently adopted the name and altered it to á-xenos. Thereafter, Greek tradition refers to the Black Sea as the "Inhospitable Sea", Πόντος Ἄξεινος Póntos Áxeinos, first attested in Pindar; the name was considered to be "ominous" and was changed into the euphemistic name "Hospitable sea", Εὔξεινος Πόντος Eúxeinos Póntos, for the first time attested in Pindar. This became the used designation for the sea in Greek. In contexts related to mythology, the older form Póntos Áxeinos remained favored, it has been erroneously suggested that the name was derived from the color of the water, or was at least related to climatic conditions. Black or dark in this context, referred to a system in which colors represent the cardinal points of the known world.
Black or dark represented the north. The symbolism based on cardinal points was used in multiple occasions and is therefore attested. For example, the "Red Sea", a body of water reported since the time of Herodotus in fact designated the Indian Ocean, together with bodies of water now known as the Persian Gulf and the Red Sea. According to the same explanation and reasoning, it is therefore considered to be impossible
The machine industry or machinery industry is a subsector of the industry, that produces and maintains machines for consumers, the industry, most other companies in the economy. This machine industry traditionally belongs to the heavy industry. Nowadays, many smaller companies in this branch are considered part of the light industry. Most manufacturers in the machinery industry are called machine factories; the machine industry is a subsector of the industry that produces a range of products from power tools, different types of machines, domestic technology to factory equipment etc. On the one hand the machine industry provides: The means of production for businesses in the agriculture, mining and construction; the means of production for public utility, such as equipment for the production and distribution of gas and water. A range of supporting equipment for all sectors of the economy, such as equipment for heating and air conditioning of buildings; these means of production are called capital goods.
Much of those production machines require regular maintenance, which becomes supplied specialized companies in the machine industry. On the other end the machinery industry supplies consumer goods, including kitchen appliances, washers, dryers and a like. Production of radio and television, however, is considered belonging to the electrical equipment industry; the machinery industry itself is a major customer of the steel industry. The production of the machinery industry varies from single-unit production and series production to mass production. Single-unit production is about constructing unique products, which are specified in specific customer requirements. Due to modular design such devices and machines can be manufactured in small series, which reduces the costs. From a certain stage in the production, the specific customer requirements are build in, the unique product is created; the machinery industry came into existence during the Industrial Revolution. Companies in this emerging field grew out of iron foundries, shipyards and repair shops.
Companies were a combination of machine factory and shipyard. Early in the 20th century several motorcycle and automobile manufacturers began their own machine factories. Prior to the industrial revolution a variety of machines existed such as clocks and running gear for mills Production of these machines were on much smaller scale in artisan workshops for the local or regional market. With the advent of the industrial revolution manufacturing began of composite tools with more complex construction, such as steam engines and steam generators for the evolving industry and transport. In addition, the emerging machine factories started making machines for production machines as textile machinery, agricultural machinery, engines for ships. During the first decades of the industrial revolution in England, from 1750, there was a concentration of labor in not yet mechanized factories. There were all kinds of new machines invented, which were made by the inventors themselves. Early in the 18th century, the first steam engines, the Newcomen engine, came into use throughout Britain and Europe, principally to pump water out of mines.
In the 1770s James Watt improved this design. He introduced a steam engine easy employable to supply a large amounts of energy, which set the mechanization of factories underway. In England certain cities concentrated on making specific products, such as specific types of textiles or pottery. Around these cities specialized machinery industry arose in order to enable the mechanization of the plants. Hereby late in the 18th century arose the first machinery industry in the UK and in Germany and Belgium; the Industrial Revolution received a further boost with the upcoming railways. These arose at the beginning of the 19th century in England as innovation in the mining industry; the work in coal mines was hard and dangerous, so there was a great need for tools to ease this work. In 1804, Richard Trevithick placed the first steam engine on rails, was in 1825 the Stockton and Darlington Railway was opened, intended to transport coals from the mine to the port. In 1835 the first train drove in continental Europe between Mechelen and Brussels, in the Netherlands in 1839 the first train drove between Amsterdam and Haarlem.
For the machinery industry this brought all sorts of new work with new machinery for metallurgy, machine tool for metalworking, production of steam engines for trains with all its necessities etc. In time the market for the machine industry became wider, specialized products were manufactured for a greater national and international market. For example, it was not uncommon in the second half of the 19th century that American steelmakers ordered their production in England, where new steelmaking techniques were more advanced. In the far east Japan would import these product until the early 1930s, the creation of an own machinery industry got underway.. The term "machinery industry" came into existence in the 19th century. One of the first times this branch of industry was recognized as such, was investigated, was in a production statistics of 1907 created by the British Ministry of Trade and Industry. In this statistic the output of the engineering industry, was divided into forty different categories, including for example, agricultural machinery, machinery for the textile industry and equipment, parts for train and tram.
The inventions of new propulsion techniques based on electric motors, internal combustion engines and gas turbines brought a new generation of machines in the 20th century from cars to household ap
Albert Kahn Associates
Albert Kahn Associates is an architectural design firm in Detroit, Michigan with a second office located in Miami, Florida. It is still active today. Recent work includes being awarded third place in the Virtual Modeling Stage of NASA’s 3D-Printed Habitat Competition for their work on martian habitats, creating the world's largest penguin conservation center, Polk Penguin Conservation Center. In earlier years, it introduced a new technology in industrial building involving a unique reinforced concrete method referred to as the Kahn System of construction using proprietary patented reinforcement steel manufactured by Trussed Concrete Steel Company; the building of automobile factories and other types of factories were revolutionized from wooden timber framing construction. Besides being an advanced technology in strength that led to wider open interior spaces, it featured a high degree of fire resistance and larger window space for light; the firm started by Albert Kahn built factories for Chrysler for over a decade, Ford Automobile for 30 years and Packard Automobile for 35 years.
Other important clients of the firm were General Motors. The firm was awarded a $40 million contract to build a tractor factory in Russia in 1928; the firm's output was over a million dollars worth of work per week by 1929. By 1939, the firm designed 19 percent of all industrial buildings in the United States and had designed some $800 million of buildings worldwide. Albert Kahn was its first and only employee then. In 1896, Kahn took on two partners: Alexander Trowbridge. All three were architects at the time with the architectural firm Rice in Detroit; the firm they opened in January 1896 was called "Nettleton and Trowbridge". At the time there was an abundance of design jobs available. Mason & Rice referred some of their work to Kahn's new firm when they had more than they could handle; the firm's first large design job in Detroit was to design Children's Hospital of Michigan. Its next major project came in 1898 from James E. Scripps to design an elaborate library with an art gallery; the Scripps Library and Museum was located adjacent to Scripps' mansion home on Trumbull Avenue at Grand River Avenue.
The dynamics of the firm changed when Trowbridge took a position at Cornell University in 1897 and Nettleton died in 1900. The firm hired designers with good reputations and an ability to work as a team with other designers. Ernest Wilby, a young Englishman from Canada, was their key designer working for the firm at the time; this new team collaborated with the Mason & Rice architectural firm to design the Palms Apartments, a building with English architecture on Jefferson Avenue at Rivard Street in Detroit. It was one of the first buildings to use reinforced concrete as a major construction material; the firm changed its name in 1901 to "architect. Joseph Boyer had hired the firm to design a factory. Boyer asked the firm to design a building to house the Burroughs Adding Machine Company, where modern mechanical calculators were made. Boyer in 1902 introduced Kahn to head of the Packard Motor Car company. Kahn's firm received several non-industrial jobs including remodeling Joy's home. Joy additionally had the firm design automobile factory buildings.
Between 1903–05, the firm designed the first nine Packard Automotive Plant buildings using traditional wooden designs that had spans no longer than 14 feet. Packard produced over 700 automobiles a year by 1905, so an expansion to the factory facility was in order; the team decided to use reinforced concrete to build the new factory space. With Albert's younger brother Julius as the key architect and engineer, Building Number 10 was constructed with the Kahn bar and other reinforced concrete products; these were manufactured at the Trussed Concrete Steel Company. This new technology for concrete changed the way; this building was built with uniquely designed steel beam reinforced concrete for reinforcement that used the Kahn bar with winged tabs on the steel bar edges that were bent back at 45 degrees to resist and counter tension stresses. This was the first time reinforced concrete was used for automobile factory construction in the United States; the new state of the art design concept featured larger open interior spaces than the old mill-framed wooden factory buildings.
The building was 322 feet long by 60 feet wide. This new factory concept of building with reinforced concrete lead to Albert Kahn Associates doing all the aviation factories for the government during World War I. In 1906, the firm designed factory buildings for the Pierce-Arrow Motor Car Company in Buffalo, New York. In 1908 the Highland Park Ford Plant was designed by the firm, it was similar to the Packard factory just a few miles away, however different from the Pierce-Arrow factory buildings that were of one-story only and had saw-tooth roofs with skylights. The Ford factory building had four stories, it was however, of reinforced concrete design using the patented Kahn System of his brother Julius, just like the Packard and Pierce-Arrow factory buildings. The Ford plant was 75 feet wide; the steel reinforced. The "Model factory" featured what was referred to as Truscon's "Daylight System" because of the many large windows. Henry Ford had the firm design his River Rouge automobile factory that started construction in 1917.
At the time Ford decided to make a ship factory for the United States Na
The United States of America known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U. S. is the third most populous country. The capital is Washington, D. C. and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico; the State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean; the U. S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The diverse geography and wildlife of the United States make it one of the world's 17 megadiverse countries.
Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago. European colonization began in the 16th century; the United States emerged from the thirteen British colonies established along the East Coast. Numerous disputes between Great Britain and the colonies following the French and Indian War led to the American Revolution, which began in 1775, the subsequent Declaration of Independence in 1776; the war ended in 1783 with the United States becoming the first country to gain independence from a European power. The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties; the United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories, displacing Native American tribes, admitting new states until it spanned the continent by 1848. During the second half of the 19th century, the Civil War led to the abolition of slavery.
By the end of the century, the United States had extended into the Pacific Ocean, its economy, driven in large part by the Industrial Revolution, began to soar. The Spanish–American War and World War I confirmed the country's status as a global military power; the United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, a permanent member of the United Nations Security Council. Sweeping civil rights legislation, notably the Civil Rights Act of 1964, the Voting Rights Act of 1965 and the Fair Housing Act of 1968, outlawed discrimination based on race or color. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 U. S. Moon landing; the end of the Cold War and the collapse of the Soviet Union in 1991 left the United States as the world's sole superpower. The United States is the world's oldest surviving federation, it is a representative democracy.
The United States is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States, other international organizations. The United States is a developed country, with the world's largest economy by nominal GDP and second-largest economy by PPP, accounting for a quarter of global GDP; the U. S. economy is post-industrial, characterized by the dominance of services and knowledge-based activities, although the manufacturing sector remains the second-largest in the world. The United States is the world's largest importer and the second largest exporter of goods, by value. Although its population is only 4.3% of the world total, the U. S. holds 31% of the total wealth in the world, the largest share of global wealth concentrated in a single country.
