Asphalt Green
The Municipal Asphalt Plant is a former asphalt plant at York Avenue and 91st Street on the Upper East Side of Manhattan in New York City, housing the Asphalt Green recreation center. The asphalt plant was completed in 1944 to designs by Ely Jacques Kahn and Robert Allan Jacobs. The current structure, originally a mixing plant, reopened as the George and Annette Murphy Center in 1984; it was attached to a conveyor belt and storage facility, both of which have been demolished. The Murphy Center is a New York City designated landmark and is listed on the National Register of Historic Places. The Municipal Asphalt Plant's post-modernist design was intended to fit the residential character of the surrounding neighborhood while also being industrial. The mixing plant was the first parabolic-arched building in the United States to use reinforced concrete. The exterior was designed with four arched ribs, The walls and roof are made of cast-in-place concrete panels, which were poured aro ...

New York, New York
New York, often called New York City or NYC, is the most populous city in the United States. With a 2020 population of 8,804,190 distributed over , New York City is also the most densely populated major city in the United States, and is more than twice as populous as second-place Los Angeles. New York City lies at the southern tip of New York State, and constitutes the geographical and demographic center of both the Northeast megalopolis and the New York metropolitan area, the largest metropolitan area in the world by urban landmass. With over 20.1 million people in its metropolitan statistical area and 23.5 million in its combined statistical area as of 2020, New York is one of the world's most populous megacities, and over 58 million people live within of the city.

Kahn And Jacobs
Ely Jacques Kahn (June 1, 1884September 5, 1972) was an American commercial architect who designed numerous skyscrapers in New York City in the twentieth century. In addition to buildings intended for commercial use, Kahn's designs ranged throughout the possibilities of architectural programs, including facilities for the film industry. Many of the buildings he designed under the 1916 Zoning Resolution feature architectural setbacks to keep the building profitably close to its permitted "envelope"; these have been likened to the stepped form of the Tower of Babel. Kahn is also known for his guidance to author Ayn Rand. Life and career Kahn was born in New York, the only son of a prosperous Austrian and French-American Jewish family. His sister Rena Rosenthal brought design wares from Europe to sell in New York, perhaps providing his earliest introduction to design. Ely Jacques Kahn traveled to Europe where he was aware of the work of architect Josef Hoffmann. He graduated from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sports Medicine
Sports medicine is a branch of medicine that deals with physical fitness and the treatment and prevention of injuries related to sports and exercise. Although most sports teams have employed team physicians for many years, it is only since the late 20th century that sports medicine emerged as a distinct field of health care. In some countries, sports medicine (or sport and exercise medicine) is a recognized medical specialty (with similar training and standards to other medical specialties). In the majority of countries where sports medicine is recognized and practiced, it is a physician (non-surgical) specialty, but in some (such as the USA), it can equally be a surgical or non-surgical medical specialty, and also a specialty field within primary care. In other contexts, the field of sports medicine encompasses the scope of both medical specialists and also allied health practitioners who work in the field of sport, such as physiotherapists, athletic trainers, podiatrists and ...

Bleachers
Bleachers (North American English), or stands, are raised, tiered rows of benches found at sports fields and other spectator events. Stairways provide access to the horizontal rows of seats, often with every other step gaining access to a row of benches. Benches range from simple planks to elaborate ones with backrests. Many bleachers are open to the ground below so that there are only the planks to sit and walk on. Some bleachers have vertical panels beneath the benches, either partially or completely blocking the way to the ground. Name origins The open seating area in baseball was called the "bleaching boards" as early as 1877. The term "bleachers" used in the sense of benches for spectators can be traced back to at least 1889; named as such because the generally uncovered wooden boards were "bleached by the sun". ''The Dickson Baseball Dictionary'' lists as a ''secondary'' definition the fans sitting in them. By the early 1900s, the term "bleachers" was being used for ...

Asphalt Concrete
Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and tarmac, bitumen macadam, or rolled asphalt in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, and the core of embankment dams. Asphalt mixtures have been used in pavement construction since the beginning of the twentieth century. It consists of mineral aggregate bound together with asphalt, laid in layers, and compacted. The process was refined and enhanced by Belgian-American inventor Edward De Smedt. The terms ''asphalt'' (or ''asphaltic'') ''concrete'', ''bituminous asphalt concrete'', and ''bituminous mixture'' are typically used only in engineering and construction documents, which define concrete as any composite material composed of mineral aggregate adhered with a binder. The abbreviation, ''AC'', is sometimes used for ''asphalt concrete'' but can also denote ''asphalt content'' or ''asphalt cement'', ...

Congelation
Congelation (from Latin: , ) was a term used in medieval and early modern alchemy for the process known today as crystallization. In the ('The Secret of Alchemy') attributed to Khalid ibn Yazid (), it is one of "the four principal operations", along with ''Solution'', ''Albification'' ('whitening'), and ''Rubification'' ('reddening'). It was one of the twelve alchemical operations involved in the creation of the philosophers' stone as described by Sir George Ripley () in his ''Compound of Alchymy'', as well as by Antoine-Joseph Pernety in his ''Dictionnaire mytho-hermétique'' (1758).. See also *Alchemical process *Magnum opus (alchemy) The Great Work (Latin: ''Magnum opus'') is an alchemical term for the process of working with the prima materia to create the philosopher's stone.

Monel
Monel is a group of alloys of nickel (from 52 to 67%) and copper, with small amounts of iron, manganese, carbon, and silicon. Monel is not a cupronickel alloy because it has less than 60% copper. Stronger than pure nickel, Monel alloys are resistant to corrosion by many aggressive agents, including rapidly flowing seawater. They can be fabricated readily by hot- and cold-working, machining, and welding. Monel was created in 1905 by Robert Crooks Stanley, who at the time worked at the International Nickel Company (Inco). Monel alloy 400 is a binary alloy of the same proportions of nickel and copper as is found naturally in the meteoritic nickel ore from the Sudbury (Ontario) mines and is therefore considered a puritan alloy. Monel was named after company president Ambrose Monell, and patented in 1906. One L was dropped, because family names were not allowed as trademarks at that time. The trademark was registered in May 1921, and the name is now a trademark of Special Metals C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prefabrication
Prefabrication is the practice of assembling components of a structure in a factory or other manufacturing site, and transporting complete assemblies or sub-assemblies to the construction site where the structure is to be located. The term is used to distinguish this process from the more conventional construction practice of transporting the basic materials to the construction site where all assembly is carried out. The term ''prefabrication'' also applies to the manufacturing of things other than structures at a fixed site. It is frequently used when fabrication of a section of a machine or any movable structure is shifted from the main manufacturing site to another location, and the section is supplied assembled and ready to fit. It is not generally used to refer to electrical or electronic components of a machine, or mechanical parts such as pumps, gearboxes and compressors which are usually supplied as separate items, but to sections of the body of the machine which in the ...

Sundial
A sundial is a horological device that tells the time of day (referred to as civil time in modern usage) when direct sunlight shines by the apparent position of the Sun in the sky. In the narrowest sense of the word, it consists of a flat plate (the ''dial'') and a gnomon, which casts a shadow onto the dial. As the Sun appears to move through the sky, the shadow aligns with different hour-lines, which are marked on the dial to indicate the time of day. The ''style'' is the time-telling edge of the gnomon, though a single point or ''nodus'' may be used. The gnomon casts a broad shadow; the shadow of the style shows the time. The gnomon may be a rod, wire, or elaborately decorated metal casting. The style must be parallel to the axis of the Earth's rotation for the sundial to be accurate throughout the year. The style's angle from horizontal is equal to the sundial's geographical latitude. The term ''sundial'' can refer to any device that uses the Sun's altitude or azimut ...

Sash Window
A sash window or hung sash window is made of one or more movable panels, or "sashes". The individual sashes are traditionally paned window (architecture), paned windows, but can now contain an individual sheet (or sheets, in the case of double glazing) of glass. History The oldest surviving examples of sash windows were installed in England in the 1670s, for example at Ham House.Louw, HJ, ''Architectural History'', Vol. 26, 1983 (1983), pp. 49–72, 144–15JSTOR The invention of the sash window is sometimes credited, without conclusive evidence, to Robert Hooke. Others see the sash window as a Dutch invention. H.J. Louw believed that the sash window was developed in England, but concluded that it was impossible to determine the exact inventor. The sash window is often found in Georgian architecture, Georgian and Victorian architecture, Victorian houses, and the classic arrangement has three panes across by two up on each of two sash, giving a ''six over six'' panel window, alth ...

Barrel Vault
A barrel vault, also known as a tunnel vault, wagon vault or wagonhead vault, is an architectural element formed by the extrusion of a single curve (or pair of curves, in the case of a pointed barrel vault) along a given distance. The curves are typically circular in shape, lending a semi-cylindrical appearance to the total design. The barrel vault is the simplest form of a vault: effectively a series of arches placed side by side (i.e., one after another). It is a form of barrel roof. As with all arch-based constructions, there is an outward thrust generated against the walls underneath a barrel vault. There are several mechanisms for absorbing this thrust. One is to make the walls exceedingly thick and strong – this is a primitive and sometimes unacceptable method. A more elegant method is to build two or more vaults parallel to each other; the forces of their outward thrusts will thus negate each other. This method was most often used in construction of churches, where sever ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East River
The East River is a saltwater tidal estuary in New York City. The waterway, which is actually not a river despite its name, connects Upper New York Bay on its south end to Long Island Sound on its north end. It separates the borough of Queens on Long Island from the Bronx on the North American mainland, and also divides Manhattan from Queens and Brooklyn, also on Long Island.Hodges, Godfrey. "East RIver" in Jackson, pp.393–93 Because of its connection to Long Island Sound, it was once also known as the ''Sound River''. The tidal strait changes its direction of flow frequently, and is subject to strong fluctuations in its current, which are accentuated by its narrowness and variety of depths. The waterway is navigable for its entire length of , and was historically the center of maritime activities in the city. Formation and description Technically a drowned valley, like the other waterways around New York City, the strait was formed approximately 11,000 years ago at the e ...
