Tarrytown Light
Tarrytown Light, also known as Kingsland Point Light and Sleepy Hollow Light, is a sparkplug lighthouse on the east side of the Hudson River in Sleepy Hollow, New York, United States. It a conical steel structure erected in the 1880s. In 1979 it was listed on the National Register of Historic Places. The need for a lighthouse to warn ships away from the shoals near the common route off Tarrytown and Ossining had been obvious by the mid-19th century. But high land values at two favored locations led the federal government to instead build it offshore. It was the only family station on the lower Hudson, the only conical steel lighthouse on the Hudson to have living quarters within it rather than attached to it, and the only lighthouse in Westchester County. It remained in use until the mid-20th century; the construction of the Tappan Zee Bridge on the shoals where it stood and the development of the General Motors Tarrytown Truck Assembly plant on land reclaimed from the rive ...

Tappan Zee Bridge (1955–2017)
The Governor Malcolm Wilson Tappan Zee Bridge, commonly known as the Tappan Zee Bridge, was a cantilever bridge in the U.S. state of New York. It was built from 1952 to 1955 to cross the Hudson River at one of its widest points, north of Midtown Manhattan, from South Nyack to Tarrytown. As an integral conduit within the New York Metropolitan Area, the bridge connected South Nyack in Rockland County with Tarrytown in Westchester County in the Lower Hudson Valley. Opened on December 14, 1955, the Tappan Zee Bridge was one of the primary crossings of the Hudson River north of New York City; it carried much of the traffic between southern New England and points west of the Hudson. The bridge was the longest bridge in New York State, a title retained by its replacement. The total length of the bridge approached . The cantilever span was , which provided a maximum clearance of over the water. The bridge was officially named after former governor Malcolm Wilson in 1994, though t ...

Industrialization
Industrialisation ( alternatively spelled industrialization) is the period of social and economic change that transforms a human group from an agrarian society into an industrial society. This involves an extensive re-organisation of an economy for the purpose of manufacturing. Historically industrialization is associated with increase of polluting industries heavily dependent on fossil fuels. With the increasing focus on sustainable development and green industrial policy practices, industrialization increasingly includes technological leapfrogging, with direct investment in more advanced, cleaner technologies. The reorganization of the economy has many unintended consequences both economically and socially. As industrial workers' incomes rise, markets for consumer goods and services of all kinds tend to expand and provide a further stimulus to industrial investment and economic growth. Moreover, family structures tend to shift as extended families tend to no longer live ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cistern
A cistern (Middle English ', from Latin ', from ', "box", from Greek ', "basket") is a waterproof receptacle for holding liquids, usually water. Cisterns are often built to catch and store rainwater. Cisterns are distinguished from wells by their waterproof linings. Modern cisterns range in capacity from a few litres to thousands of cubic metres, effectively forming covered reservoirs. Origins Early domestic and agricultural use Waterproof lime plaster cisterns in the floors of houses are features of Neolithic village sites of the Levant at, for instance, Ramad and Lebwe, and by the late fourth millennium BC, as at Jawa in northeastern Lebanon, cisterns are essential elements of emerging water management techniques in dry-land farming communities. The Ancient Roman impluvium, a standard feature of the domus house, generally had a cistern underneath. The impluvium and associated structures collected, filtered, cooled, and stored the water, and also cooled and ventilated ...

Fog Bell
A fog bell is a navigation mark used as an audible aid to navigation in seafaring, especially in fog and poor visibility. Floating navigation signs with bells are called bell buoys. On ships, the ship's bell is used for sound signals. Due to more suitable sound generators, but also the development and spread of radar, satellite navigation and Electronic Chart Display and Information System, electronic charting systems, fog bells have lost their importance for maritime navigation. Maritime marks on land Starting in the 18th century, fog signals were given for seafaring in Europe, initially cannons or guns. In 1766, the first bell for this purpose was installed in Nidingen on the Baltic Sea.Thomas Tag''Fog Bells'' United States Lighthouse Society website. Retrieved September 27, 2021. These were initially rung by hand, which was a chore during prolonged fog, others used mechanisms similar to clockwork that had to be wound periodically.

Thermal Insulation
Thermal insulation is the reduction of heat transfer (i.e., the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence. Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials. Heat flow is an inevitable consequence of contact between objects of different temperature. Thermal insulation provides a region of insulation in which thermal conduction is reduced, creating a thermal break or thermal barrier, or thermal radiation is reflected rather than absorbed by the lower-temperature body. The insulating capability of a material is measured as the inverse of thermal conductivity (k). Low thermal conductivity is equivalent to high insulating capability ( resistance value). In thermal engineering, other important properties of insulating materials are product density (ρ) and specific heat capacity (c). Definition T ...

Catwalk
A fashion show ( French ''défilé de mode'') is an event put on by a fashion designer to showcase their upcoming line of clothing and/or accessories during a fashion week. Fashion shows debut every season, particularly the Spring/Summer and Fall/Winter seasons. This is where the latest fashion trends are made. The four major fashion weeks in the world, collectively known as the "Big 4", are those in Paris, London, Milan, and New York. Berlin fashion week is also of global importance. In a typical fashion show, models walk the catwalk dressed in the clothing created by the designer. Clothing is illuminated on the catwalk using various forms of lighting and special effects. The order in which each model walks out, wearing a specific outfit, is usually planned in accordance with the statement that the designer wants to make about their collection. It is then up to the audience to not only try to understand what the designer is trying to say, but to also visually deconstruct ea ...

Porthole
A porthole, sometimes called bull's-eye window or bull's-eye, is a generally circular window used on the hull of ships to admit light and air. Though the term is of maritime origin, it is also used to describe round windows on armored vehicles, aircraft, automobiles (the Ford Thunderbird a notable example) and even spacecraft. On a ship, the function of a porthole, when open, is to permit light and fresh air to enter the dark and often damp below- deck quarters of the vessel. It also affords below-deck occupants a limited view to the outside world. When closed, the porthole provides a strong water-tight, weather-tight and sometimes light-tight barrier. A porthole on a ship may also be called a sidescuttle or side scuttle (side hole), as officially termed in the International Convention for the Safety of Life at Sea. This term is used in the U.S. Code of Federal Regulations. It is also used in related rules and regulations for the construction of ships. The use of the word "si ...

Caisson (engineering)
In geotechnical engineering, a caisson ( or ; borrowed from French ''caisson'', from Italian ''cassone'', meaning ''large box'', an augmentative of ''cassa'') is a watertight retaining structure used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, or for the repair of ships. Caissons are constructed in such a way that the water can be pumped out, keeping the work environment dry. When piers are being built using an open caisson, and it is not practical to reach suitable soil, friction pilings may be driven to form a suitable sub-foundation. These piles are connected by a foundation pad upon which the column pier is erected. Caisson engineering has been used at least since the 18th century, and was notably used in the construction of the Brooklyn Bridge, which was completed in 1883. Types To install a caisson in place, it is brought down through soft mud until a suitable foundation material is encountered. While bedrock is pref ...

Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications and are ...

Foundation (architecture)
In engineering, a foundation is the element of a structure which connects it to the ground, transferring loads from the structure to the ground. Foundations are generally considered either shallow or deep. Foundation engineering is the application of soil mechanics and rock mechanics ( geotechnical engineering) in the design of foundation elements of structures. Purpose Foundations provide the structure's stability from the ground: * To distribute the weight of the structure over a large area in order to avoid overloading the underlying soil (possibly causing unequal settlement). * To anchor the structure against natural forces including earthquakes, floods, droughts, frost heaves, tornadoes and wind. * To provide a level surface for construction. * To anchor the structure deeply into the ground, increasing its stability and preventing overloading. * To prevent lateral movements of the supported structure (in some cases).
