Allegheny Arsenal
The Allegheny Arsenal, established in 1814, was an important supply and manufacturing center for the Union Army during the American Civil War, and the site of the single largest civilian disaster during the war. It was located in the community of Lawrenceville (Pittsburgh), Lawrenceville, Pennsylvania, which was annexed by the city of Pittsburgh in 1868. Today, the site is the location of the nine-acre Arsenal Park as well as Arsenal Middle School, a county health services complex, and a large condominium development. In 2012, officials from the Pittsburgh History & Landmarks Foundation began drawing attention to the deteriorating arsenal structures. Origins The Arsenal was established by the U.S. Army Ordnance Department near Pittsburgh in 1814. It was situated on of land bordering the Allegheny River in the community of Lawrenceville (Pittsburgh), Lawrenceville. The site was bounded by 39th Street, 40th Street, and Penn Avenue, and bisected by Butler Street, which was and sti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lawrenceville (Pittsburgh)
Lawrenceville is one of the largest neighborhood areas in Pittsburgh in the U.S. state of Pennsylvania. It is located northeast of downtown, and like many of the city's riverfront neighborhoods, it has an industrial past. The city considers Lawrenceville three neighborhoods, Upper Lawrenceville, Central Lawrenceville, and Lower Lawrenceville, but these distinctions have little practical effect. Accordingly, Lawrenceville is almost universally treated as being a single large neighborhood. In 2019, the Lawrenceville Historic District, which encompasses the majority of the neighborhood, was added to the National Register of Historic Places. History Lawrenceville was founded in 1814 by William B. Foster, father of composer Stephen Foster, who was born there in 1826. It is named for Captain James Lawrence, hero of the War of 1812, famous for his dying words, " Don't Give Up The Ship!" Lawrenceville was selected as home to the Allegheny Arsenal, due to "The area's accessibility to r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smolder
Smouldering (British English) or smoldering (American English; see spelling differences) is the slow, flameless form of combustion, sustained by the heat evolved when oxygen directly attacks the surface of a condensed-phase fuel. Many solid materials can sustain a smouldering reaction, including coal, cellulose, wood, cotton, tobacco, cannabis, peat, plant litter, humus, synthetic foams, charring polymers including polyurethane foam and some types of dust. Common examples of smouldering phenomena are the initiation of residential fires on upholstered furniture by weak heat sources (e.g., a cigarette, a short-circuited wire), and the persistent combustion of biomass behind the flaming front of wildfires. Fundamentals The fundamental difference between smouldering and flaming combustion is that smouldering occurs on the surface of the solid rather than in the gas phase. Smouldering is a surface phenomenon but can propagate to the interior of a porous fuel if it is permeable to f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sharpsburg, Maryland
Sharpsburg is a town in Washington County, Maryland. The town is approximately south of Hagerstown. Its population was 705 at the 2010 census. During the American Civil War, the Battle of Antietam, sometimes referred to as the Battle of Sharpsburg, was fought on what is now Antietam National Battlefield, in the vicinity of Antietam Creek. History The first American of European descent to own land in what would eventually become Sharpsburg was the one-time indian trader Edmund Cartledge. By the time Cartledge surveyed his "Hickory Tavern" land tract in 1737, the Great Philadelphia Wagon Road was already well established over the path that would become Sharpsburg's main street. Hickory Tavern is noted in the patent as between the wagon road and Garrison Spring, today's Big Spring. Thousands of immigrants used this route of the wagon road traveling from Pennsylvania as far south as the Carolinas. On May 1, 1755 the road was used by Major general Edward Braddock, colonial gov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antietam
The Battle of Antietam (), or Battle of Sharpsburg particularly in the Southern United States, was a battle of the American Civil War fought on September 17, 1862, between Confederate Gen. Robert E. Lee's Army of Northern Virginia and Union Gen. George B. McClellan's Army of the Potomac near Sharpsburg, Maryland and Antietam Creek. Part of the Maryland Campaign, it was the first field army–level engagement in the Eastern Theater of the American Civil War to take place on Union soil. It remains the bloodiest day in American history, with a combined tally of 22,717 dead, wounded, or missing. Although the Union army suffered heavier casualties than the Confederates, the battle was a major turning point in the Union's favor. After pursuing Confederate Gen. Robert E. Lee into Maryland, Maj. Gen. George B. McClellan of the Union Army launched attacks against Lee's army who were in defensive positions behind Antietam Creek. At dawn on September 17, Maj. Gen. Joseph Hooker's corp ...

Dupont And Company
DuPont de Nemours, Inc., commonly shortened to DuPont, is an American multinational chemical company first formed in 1802 by French-American chemist and industrialist Éleuthère Irénée du Pont de Nemours. The company played a major role in the development of Delaware and first arose as a major supplier of gunpowder. DuPont developed many polymers such as Vespel, neoprene, nylon, Corian, Teflon, Mylar, Kapton, Kevlar, Zemdrain, M5 fiber, Nomex, Tyvek, Sorona, Corfam and Lycra in the 20th century, and its scientists developed many chemicals, most notably Freon (chlorofluorocarbons), for the refrigerant industry. It also developed synthetic pigments and paints including ChromaFlair. In 2015, DuPont and the Dow Chemical Company agreed to a reorganization plan in which the two companies would merge and split into three. As a merged entity, DuPont simultaneously acquired Dow and renamed itself to DowDuPont on August 31, 2017, and after 18 months spin off the merged entity's mater ...

Coroner's Jury
A coroner's jury is a body convened to assist a coroner in an inquest, that is, in determining the identity of a deceased person and the cause of death. The laws on its role and function vary by jurisdiction. United Kingdom In England and Wales, all inquests were once conducted with a jury. They acted somewhat like a grand jury, determining whether a person should be committed to trial in connection to a death. Such a jury was made up of up to twenty-three men, and required the votes of twelve to render a decision. Similar to a grand jury, a coroner's jury merely accused, it did not convict. There are no coroners in Scotland, which has its own legal system. The Scottish equivalent of an inquest is a Fatal Accident Inquiry, held where there is a sudden, suspicious, accidental, or unexplained death, which is ordered by a Procurator Fiscal and presided over by a Sheriff without a jury. Since 1927, coroner's juries have rarely been used in England. Under the Coroners Act 1988, a j ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gunpowder
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon (in the form of charcoal) and potassium nitrate (saltpeter). The sulfur and carbon act as fuels while the saltpeter is an oxidizer. Gunpowder has been widely used as a propellant in firearms, artillery, rocketry, and pyrotechnics, including use as a blasting agent for explosives in quarrying, mining, building pipelines and road building. Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance. Low explosives deflagrate (i.e., burn at subsonic speeds), whereas high explosives detonate, producing a supersonic shockwave. Ignition of gunpowder packed behind a projectile generates enough pressure to force the shot from the muzzle at high speed, but usually not enough force to rupture the gun barrel. It thus makes a good propellan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horseshoe
A horseshoe is a fabricated product designed to protect a horse hoof from wear. Shoes are attached on the palmar surface (ground side) of the hooves, usually nailed through the insensitive hoof wall that is anatomically akin to the human toenail, although much larger and thicker. However, there are also cases where shoes are glued. Horseshoes are available in a wide variety of materials and styles, developed for different types of horse and for the work they do. The most common materials are steel and aluminium, but specialized shoes may include use of rubber, plastic, magnesium, titanium, or copper.Price, Steven D. (ed.) ''The Whole Horse Catalog: Revised and Updated'' New York:Fireside 1998 , pp. 84–87. Steel tends to be preferred in sports in which a strong, long-wearing shoe is needed, such as polo, eventing, show jumping, and western riding events. Aluminium shoes are lighter, making them common in horse racing where a lighter shoe is desired, and often facilitate ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turney House
The Turney House is a historic house in the Lawrenceville neighborhood of Pittsburgh, Pennsylvania, and a designated Pittsburgh historic landmark. It was built circa 1851 by Lucian B. Turney, a carpenter who also served on the Lawrenceville Borough Council during the 1850s. It was also the residence of Turney's daughter Margaret, who at age 17 was one of 78 workers killed in the 1862 Allegheny Arsenal Explosion, the deadliest civilian disaster during the U.S. Civil War. After the demolition of 184 38th Street in 2011, the Turney House is the only surviving house known to be associated with a victim of the explosion. Another one of Turney's children, Olive, became a successful artist. In 1996, the house was purchased by architectural historian Carol Peterson, who restored it to a period-appropriate appearance. History Built by Lucian B. Turney, a 19th-century carpenter, member of the Lawrenceville Borough Council, and a member of the Lawrenceville School Board (1856), Turney H ...
