Hockessin, Delaware
Hockessin () is a census-designated place (CDP) in New Castle County, Delaware, United States. The population was 13,527 at the 2010 census. History Hockessin came into existence as a little village in 1688 when several families settled in the area. The village was named after the Lenape word ''hokes'', meaning good bark or good bark hill. There is a second and more likely origin for the name. While the word Hockessin does look like a Native American word, the name Hockessin did not show up on any early maps until many years after the Hockessin Meeting House was built and what is now the Village of Hockessin was never settled by the Native Americans, while they did have a hunting camp nearby. There was no town name Hockessin and the area was referred to as Mill Creek Hundred. The actual name is believed to be derived from one of the first settled properties which was named Occasion and settled by William Cox in 1726 and also the location of the first Quaker meetings in the area be ...

Newspapers
A newspaper is a periodical publication containing written information about current events and is often typed in black ink with a white or gray background. Newspapers can cover a wide variety of fields such as politics, business, sports and art, and often include materials such as opinion columns, weather forecasts, reviews of local services, obituaries, birth notices, crosswords, editorial cartoons, comic strips, and advice columns. Most newspapers are businesses, and they pay their expenses with a mixture of subscription revenue, newsstand sales, and advertising revenue. The journalism organizations that publish newspapers are themselves often metonymically called newspapers. Newspapers have traditionally been published in print (usually on cheap, low-grade paper called newsprint). However, today most newspapers are also published on websites as online newspapers, and some have even abandoned their print versions entirely. Newspapers developed in the 17th ...

DuPont People
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 mate ...

People With Polio
Poliomyelitis (often simply called polio) is an acute viral infection that involves the gastrointestinal tract and occasionally the central nervous system. Poliovirus is acquired by faecal–oral or oral transmission. Prior to the introduction of a polio vaccine in 1955, infection was common, with epidemics during the summer and autumn of temperate countries. Polio eradication efforts have reduced the number of estimated polio cases worldwide by more than 99% since the mid-1980s. Most infections are asymptomatic; a small number cause a minor illness that is indistinguishable from many other viral illnesses; less than 1% result in acute flaccid paralysis. This article lists people who had the paralytic form of polio. The extent of paralysis varies from part of a limb to quadriplegia and respiratory failure. The latter was often treated with an iron lung. Around 30–40 years after contracting paralytic poliomyelitis, about 25–40% of cases lead to post-polio syndrome. Symptoms ...

People From St
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Poliomyelitis
Poliomyelitis, commonly shortened to polio, is an infectious disease caused by the poliovirus. Approximately 70% of cases are asymptomatic; mild symptoms which can occur include sore throat and fever; in a proportion of cases more severe symptoms develop such as headache, neck stiffness, and paresthesia. These symptoms usually pass within one or two weeks. A less common symptom is permanent paralysis, and possible death in extreme cases.. Years after recovery, post-polio syndrome may occur, with a slow development of muscle weakness similar to that which the person had during the initial infection. Polio occurs naturally only in humans. It is highly infectious, and is spread from person to person either through fecal-oral transmission (e.g. poor hygiene, or by ingestion of food or water contaminated by human feces), or via the oral-oral route. Those who are infected may spread the disease for up to six weeks even if no symptoms are present. The disease may be diagnosed by ...
