Elza, Tennessee
Elza was a community in Anderson County, Tennessee, that existed before 1942, when the area was acquired for the Manhattan Project. Its site is now part of the city of Oak Ridge, Tennessee. History Elza formed around a flagstop on the Louisville and Nashville Railroad. The community had a country store but no post office, instead receiving mail through the nearby community of Dossett., National Register of Historic Places Multiple Property Documentation Form, July 1991. Section E, page 5. The community's name was derived from the surname of a railroad construction engineer named Paul Elza. Construction materials for a bridge over the Clinch River and an underpass near Dossett were marked "Elza" and were delivered to a shed near the railroad tracks. William "Fiddlin' Bill" Sievers, an early country music guitarist and member of the Tennessee Ramblers band, was born in the Elza area in 1875.Charles WolfeThe Tennessee Ramblers: Ramblin' On."

Country Music
Country (also called country and western) is a genre of popular music that originated in the Southern and Southwestern United States in the early 1920s. It primarily derives from blues, church music such as Southern gospel and spirituals, old-time, and American folk music forms including Appalachian, Cajun, Creole, and the cowboy Western music styles of Hawaiian, New Mexico, Red Dirt, Tejano, and Texas country. Country music often consists of ballads and honky-tonk dance tunes with generally simple form, folk lyrics, and harmonies often accompanied by string instruments such as electric and acoustic guitars, steel guitars (such as pedal steels and dobros), banjos, and fiddles as well as harmonicas. Blues modes have been used extensively throughout its recorded history. The term ''country music'' gained popularity in the 1940s in preference to '' hillbilly music'', with "country music" being used today to describe many styles and subgenres. It came to encomp ...

Uranium
Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years. The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143 neutrons). Uranium has the highest atomic weight of the primordially occurring elements. Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. In nature, uranium is found as uranium-238 (99. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polychlorinated Biphenyl
Polychlorinated biphenyls (PCBs) are highly carcinogenic chemical compounds, formerly used in industrial and consumer products, whose production was banned in the United States by the Toxic Substances Control Act in 1979 and internationally by the Stockholm Convention on Persistent Organic Pollutants in 2001. They are organic chlorine compounds with the formula C12 H10−''x'' Cl''x''; they were once widely used in the manufacture of carbonless copy paper, as heat transfer fluids, and as dielectric and coolant fluids for electrical equipment. Because of their longevity, PCBs are still widely in use, even though their manufacture has declined drastically since the 1960s, when a host of problems were identified. With the discovery of PCBs' environmental toxicity, and classification as persistent organic pollutants, their production was banned by United States federal law in 1978, and by the Stockholm Convention on Persistent Organic Pollutants in 2001.

Uranium Ore
Uranium ore deposits are economically recoverable concentrations of uranium Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weak ... within the Earth's crust (geology), crust. Uranium is one of the more common elements in the Earth's crust, being 40 times more common than silver and 500 times more common than gold. It can be found almost everywhere in rock, soil, rivers, and oceans. The challenge for commercial uranium extraction is to find those areas where the concentrations are adequate to form an economically viable deposit. The primary use for uranium obtained from mining is in fuel for nuclear reactors. Globally, the distribution of uranium ore deposits is widespread on all continents, with the largest deposits found in Australia, Kazakhstan, and Canada. To date, high-grade deposi ...

Warehouse
A warehouse is a building for storing goods. Warehouses are used by manufacturers, importers, exporters, wholesalers, transport businesses, customs, etc. They are usually large plain buildings in industrial parks on the outskirts of cities, towns, or villages. Warehouses usually have loading docks to load and unload goods from trucks. Sometimes warehouses are designed for the loading and unloading of goods directly from railways, airports, or seaports. They often have cranes and forklifts for moving goods, which are usually placed on ISO standard pallets and then loaded into pallet racks. Stored goods can include any raw materials, packing materials, spare parts, components, or finished goods associated with agriculture, manufacturing, and production. In India and Hong Kong, a warehouse may be referred to as a "godown". There are also godowns in the Shanghai Bund.

Manhattan Engineer District
The Manhattan Project was a research and development undertaking during World War II that produced the first nuclear weapons. It was led by the United States with the support of the United Kingdom and Canada. From 1942 to 1946, the project was under the direction of Major General Leslie Groves of the U.S. Army Corps of Engineers. Nuclear physicist Robert Oppenheimer was the director of the Los Alamos Laboratory that designed the actual bombs. The Army component of the project was designated the Manhattan District as its first headquarters were in Manhattan; the placename gradually superseded the official codename, Development of Substitute Materials, for the entire project. Along the way, the project absorbed its earlier British counterpart, Tube Alloys. The Manhattan Project began modestly in 1939, but grew to employ more than 130,000 people and cost nearly US$2 billion (equivalent to about $ billion in ). Over 90 percent of the cost was for building factories and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Clinton, Tennessee
Clinton is a city in and the county seat of Anderson County, Tennessee, United States. Clinton is included in the Knoxville metropolitan area. Its population was 10,056 at the 2020 census. History Prehistoric Native American habitation was not uncommon throughout the Clinch valley, especially during the Woodland period (1000 B.C. – 1000 A.D.) and the Mississippian period (1000–1550 A.D.). A number of such habitation sites were excavated in the 1930s and 1950s in anticipation of the construction of Norris Dam and Melton Hill Dam, respectively. The Melton Hill excavations uncovered two substantial Woodland period villages along the Clinch at Bull Bluff and Freels Bend, both approximately downstream from Clinton. By the time Euro-American explorers and long hunters arrived in the Clinch valley in the mid-18th century, what is now Anderson County was part of a vast stretch of land claimed by the Cherokee. Although the Treaty of Holston, signed in 1791, was intended as a ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Security Guard
A security guard (also known as a security inspector, security officer, or protective agent) is a person employed by a government or private party to protect the employing party's assets (property, people, equipment, money, etc.) from a variety of hazards (such as criminal activity, waste, damaged property, unsafe worker behavior, etc.) by enforcing preventative measures. Security guards do this by maintaining a high-visibility presence to deter illegal and inappropriate actions, looking (either directly, through patrols, or indirectly, by monitoring alarm, alarm systems or closed-circuit television, video surveillance cameras) for signs of crime or other hazards (such as a fire), taking action to minimize damage (such as warning and escorting trespassers off property), and reporting any incidents to their clients and emergency services (such as the police or paramedics), as appropriate. Security officers are generally uniformed to represent their lawful authority to protect priv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
