Croton Aqueduct
The Croton Aqueduct or Old Croton Aqueduct was a large and complex water distribution system constructed for New York City between 1837 and 1842. The great aqueducts, which were among the first in the United States, carried water by gravity from the Croton River in Westchester County to reservoirs in Manhattan. It was built because local water resources had become polluted and inadequate for the growing population of the city. Although the aqueduct was largely superseded by the New Croton Aqueduct, which was built in 1890, the Old Croton Aqueduct remained in service until 1955. Background The island of Manhattan, surrounded by brackish rivers, had a limited supply of freshwater available. It dwindled as the city grew rapidly after the American Revolutionary War, and freshwater sources became polluted by effluent. Before the aqueduct was constructed, residents of New York obtained water from cisterns, wells, natural springs, and other bodies of water. But rapid population growth i ...

High Bridge (New York City)
The High Bridge (originally the Aqueduct Bridge) is the oldest bridge in New York City, having originally opened as part of the Croton Aqueduct in 1848 and reopened as a pedestrian walkway in 2015 after being closed for over 45 years. A steel arch bridge with a height of over the Harlem River, it connects the New York City boroughs of the Bronx and Manhattan. The eastern end is located in the Highbridge section of the Bronx near the western end of West 170th Street, and the western end is located in Highbridge Park in Manhattan, roughly parallel to the end of West 174th Street. High Bridge was originally completed in 1848 with 16 individual stone arches. In 1928, the five that spanned the Harlem River were replaced by a single steel arch. The bridge was closed to all traffic from around 1970 until its restoration, which began in 2009. The bridge was reopened to pedestrians and bicycles on June 9, 2015. The bridge is operated and maintained by the New York City Department o ... [...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 ...

Gravity Feed
Gravity feed is the use of earth's gravity to move something (usually a liquid) from one place to another. It is a simple means of moving a liquid without the use of a pump. A common application is the supply of fuel to an internal combustion engine by placing the fuel tank above the engine, e.g. in motorcycles, lawn mowers, etc. A non-liquid application is the carton flow shelving system. Ancient Roman aqueducts were gravity-fed, as water supply systems to remote villages in developing countries often are. In this case the flow of water to the village is provided by the hydraulic head, the vertical distance from the intake at the source to the outflow in the village, on which gravity acts; while it is opposed by the friction in the pipe which is determined primarily by the length and diameter of the pipe as well as by its age and the material of which it is made.

West Point Military Academy
The United States Military Academy (USMA), also known metonymically as West Point or simply as Army, is a United States service academy in West Point, New York.

Cholera
Cholera is an infection of the small intestine by some strains of the bacterium ''Vibrio cholerae''. Symptoms may range from none, to mild, to severe. The classic symptom is large amounts of watery diarrhea that lasts a few days. Vomiting and muscle cramps may also occur. Diarrhea can be so severe that it leads within hours to severe dehydration and electrolyte imbalance. This may result in sunken eyes, cold skin, decreased skin elasticity, and wrinkling of the hands and feet. Dehydration can cause the skin to turn bluish. Symptoms start two hours to five days after exposure. Cholera is caused by a number of types of ''Vibrio cholerae'', with some types producing more severe disease than others. It is spread mostly by unsafe water and unsafe food that has been contaminated with human feces containing the bacteria. Undercooked shellfish is a common source. Humans are the only known host for the bacteria. Risk factors for the disease include poor sanitation, not enough clea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellow Fever
Yellow fever is a viral disease of typically short duration. In most cases, symptoms include fever, chills, loss of appetite, nausea, muscle pains – particularly in the back – and headaches. Symptoms typically improve within five days. In about 15% of people, within a day of improving the fever comes back, abdominal pain occurs, and liver damage begins causing yellow skin. If this occurs, the risk of bleeding and kidney problems is increased. The disease is caused by the yellow fever virus and is spread by the bite of an infected mosquito. It infects humans, other primates, and several types of mosquitoes. In cities, it is spread primarily by ''Aedes aegypti'', a type of mosquito found throughout the tropics and subtropics. The virus is an RNA virus of the genus ''Flavivirus''. The disease may be difficult to tell apart from other illnesses, especially in the early stages. To confirm a suspected case, blood-sample testing with polymerase chain reaction is required. A saf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temperance Movement
The temperance movement is a social movement promoting temperance or complete abstinence from consumption of alcoholic beverages. Participants in the movement typically criticize alcohol intoxication or promote teetotalism, and its leaders emphasize alcohol's negative effects on people's health, personalities and family lives. Typically the movement promotes alcohol education and it also demands the passage of new laws against the sale of alcohol, either regulations on the availability of alcohol, or the complete prohibition of it. During the 19th and early 20th centuries, the temperance movement became prominent in many countries, particularly in English-speaking, Scandinavian, and majority Protestant ones, and it eventually led to national prohibitions in Canada (1918 to 1920), Norway (spirits only from 1919 to 1926), Finland (1919 to 1932), and the United States (1920 to 1933), as well as provincial prohibition in India (1948 to present). A number of temperance organiza ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
