Snow Shovel
A snow shovel is a specialized shovel designed for snow removal. Snow shovels come in several different designs, each of which is designed to move snow in a different way. Removing snow with a snow shovel has health and injury risks, but can also have significant health benefits when the snow shovel is used correctly. History The earliest known snow shovel was found in a bog in Russia. Estimated to be 6,000 years old, its blade was made from a carved elk antler section. According to archaeologists, the antler piece was tied to a wood or bone handle. Features All snow shovels consist of a handle and a scoop. Sometimes there may be a shaft connecting handle and scoop, while in other snow shovels, the handle is extended and attaches directly to the scoop. Most snow shovels are designed for either pushing snow or lifting snow, although some are crossovers which can do either job. Some snow shovel scoops have sharpened blades which can chip away and lever up slabs of ice. Handles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snow Removal
Snow removal or snow clearing is the job of removing snow after a snowfall to make travel easier and safer. This is done by both individual households and by governments and institutions. De-icing and anti-icing De-icing is defined as removal of existing snow, ice or frost from a roadway, airport runway, roof, or other surface. It includes both mechanical means, such as plowing, vacuuming or scraping, and chemical means, such as application of salt or other ice-melting chemicals. Anti-icing is treatment with ice-melting chemicals before or during the onset of a storm in order to prevent or delay the formation and adhesion of ice and snow to the surface. Brine, or wetted salt, is usually applied shortly before the beginning of a snowstorm. When properly performed, anti-icing can significantly reduce the amount of salt required and allow easier removal by mechanical methods, including plowing. The de-icing of roads has historically been accomplished by snowplows or specially de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chicago Tribune
The ''Chicago Tribune'' is a daily newspaper based in Chicago, Illinois, United States, owned by Tribune Publishing. Founded in 1847, and formerly self-styled as the "World's Greatest Newspaper" (a slogan for which WGN radio and television are named), it remains the most-read daily newspaper in the Chicago metropolitan area and the Great Lakes region. It had the sixth-highest circulation for American newspapers in 2017. In the 1850s, under Joseph Medill, the ''Chicago Tribune'' became closely associated with the Illinois politician Abraham Lincoln, and the Republican Party's progressive wing. In the 20th century under Medill's grandson, Robert R. McCormick, it achieved a reputation as a crusading paper with a decidedly more American-conservative anti-New Deal outlook, and its writing reached other markets through family and corporate relationships at the ''New York Daily News'' and the ''Washington Times-Herald.'' The 1960s saw its corporate parent owner, Tribune Company, rea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yale University Art Gallery
The Yale University Art Gallery (YUAG) is the oldest university art museum in the Western Hemisphere. It houses a major encyclopedic collection of art in several interconnected buildings on the campus of Yale University in New Haven, Connecticut. Although it embraces all cultures and periods, the gallery emphasizes early Italian painting, African sculpture, and modern art. History The gallery was founded in 1832, when patriot-artist John Trumbull donated more than 100 paintings of the American Revolution to Yale College and designed the original Picture Gallery. This building, on the university's Old Campus, was razed in 1901. Street Hall, designed by Peter Bonnett Wight, was opened as the Yale School of the Fine Arts in 1866, and included exhibition galleries on the second floor. The exterior was in a neo-Gothic style, with an appearance influenced by 13th-century Venetian palaces. These spaces are the oldest ones still in use as part of the Yale University Art Gallery.

Marcel Duchamp
Henri-Robert-Marcel Duchamp (, , ; 28 July 1887 – 2 October 1968) was a French painter, sculptor, chess player, and writer whose work is associated with Cubism, Dada, and conceptual art. Duchamp is commonly regarded, along with Pablo Picasso and Henri Matisse, as one of the three artists who helped to define the revolutionary developments in the plastic arts in the opening decades of the 20th century, responsible for significant developments in painting and sculpture. Duchamp has had an immense impact on twentieth-century and twenty first-century art, and he had a seminal influence on the development of conceptual art. By the time of World War I he had rejected the work of many of his fellow artists (such as Henri Matisse) as "retinal" art, intended only to please the eye. Instead, Duchamp wanted to use art to serve the mind. Early life and education Marcel Duchamp was born at Blainville-Crevon in Normandy, France, to Eugène Duchamp and Lucie Duchamp (formerly Lucie Nicolle) ...

Readymades Of Marcel Duchamp
The readymades of Marcel Duchamp are ordinary manufactured objects that the artist selected and modified, as an antidote to what he called "retinal art".Tomkins: ''Duchamp: A Biography'', page 158. By simply choosing the object (or objects) and repositioning or joining, titling and signing it, the found object became art. Duchamp was not interested in what he called "retinal art"—art that was only visual—and sought other methods of expression. As an antidote to retinal art he began creating readymades in 1914, when the term was commonly used in the United States to describe manufactured items to distinguish them from handmade goods. He selected the pieces on the basis of "visual indifference",Cabanne: ''Dialogs with Marcel Duchamp'', Thames and Hudson (1971), page 48. ''Cabanne: What determined your choice of readymades? Duchamp: That depended on the object. In general, I had to beware, at the end of fifteen days, you begin to like it or hate it. You have to approach somethi ...

In Advance Of The Broken Arm
''In Advance of the Broken Arm'', also called ''Prelude to a Broken Arm'', is a 1915 sculpture by Dada artist Marcel Duchamp that consisted of a regular snow shovel with "from Marcel Duchamp 1915" painted on the handle. One explanation for the title is that without the shovel to remove snow, one might fall and break an arm. This type of humor is not atypical of dadaist work. An antidote to what Duchamp called " retinal art", ''In Advance of the Broken Arm'' was the second of a series of sculptures that he named " ready-mades", the most famous of which is his 1917 ''Fountain''. At the time, the term "ready-made" referred to manufactured goods as opposed to handmade goods, but Duchamp used the term to describe "an ordinary object elevated to the dignity of a work of art by the mere choice of an artist". The original was hung from a wire in the studio and has since been lost. A replica of the sculpture is on display at the Yale University Art Gallery The Yale University Art Gal ...

Myocardial Infarction
A myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops to the coronary artery of the heart, causing damage to the heart muscle. The most common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck or jaw. Often it occurs in the center or left side of the chest and lasts for more than a few minutes. The discomfort may occasionally feel like heartburn. Other symptoms may include shortness of breath, nausea, feeling faint, a cold sweat or feeling tired. About 30% of people have atypical symptoms. Women more often present without chest pain and instead have neck pain, arm pain or feel tired. Among those over 75 years old, about 5% have had an MI with little or no history of symptoms. An MI may cause heart failure, an irregular heartbeat, cardiogenic shock or cardiac arrest. Most MIs occur due to coronary artery disease. Risk factors include high blood pressure, smoking, diabetes, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
