Herman Andrew Affel
Herman Andrew Affel (August 4, 1893 – October 13, 1972) was an American electrical engineer who invented the modern coaxial cable. Biography He was born on August 4, 1893. He attended MIT. He later married Bertha May Plummer. From MIT he went to work at Bell Laboratories. Among other projects he worked with Lloyd Espenschied on the characteristics of coaxial cable. Espenschied and Affel jointly applied for a patent on a wideband coaxial cable system of transmission, filed in 1929 and granted in 1934. The invention was disclosed in a prize-winning paper published in AIEE's Electrical Engineering in October 1934. He died on October 13, 1972. Legacy In 2006 Affel was inducted into the National Inventors Hall of Fame The National Inventors Hall of Fame (NIHF) is an American not-for-profit organization, founded in 1973, which recognizes individual engineers and inventors who hold a U.S. patent of significant technology. Besides the Hall of Fame, it also oper .... US Paten ...

Nursing Home
A nursing home is a facility for the residential care of elderly or disabled people. Nursing homes may also be referred to as skilled nursing facility (SNF) or long-term care facilities. Often, these terms have slightly different meanings to indicate whether the institutions are public or private, and whether they provide mostly assisted living, or nursing care and emergency medical care. Nursing homes are used by people who do not need to be in a hospital, but cannot be cared for at home. The nursing home facility nurses have the responsibilities of caring for the patients' medical needs and also the responsibility of being in charge of other employees, depending on their ranks. Most nursing homes have nursing aides and skilled nurses on hand 24 hours a day. In the United States, while nearly 1 in 10 residents age 75 to 84 stays in a nursing home for five or more years, nearly 3 in 10 residents in that age group stay less than 100 days, the maximum duration covered by Medicare, ...

United States Department Of War
The United States Department of War, also called the War Department (and occasionally War Office in the early years), was the United States Cabinet department originally responsible for the operation and maintenance of the United States Army, also bearing responsibility for naval affairs until the establishment of the Navy Department in 1798, and for most land-based air forces until the creation of the Department of the Air Force on September 18, 1947. The Secretary of War, a civilian with such responsibilities as finance and purchases and a minor role in directing military affairs, headed the War Department throughout its existence. The War Department existed from August 7, 1789 until September 18, 1947, when it split into the Department of the Army and the Department of the Air Force. The Department of the Army and Department of the Air Force later joined the Department of the Navy under the United States Department of Defense in 1949. History 18th century The Departme ...

Isolationist
Isolationism is a political philosophy advocating a national foreign policy that opposes involvement in the political affairs, and especially the wars, of other countries. Thus, isolationism fundamentally advocates neutrality and opposes entanglement in military alliances and mutual defense pacts. In its purest form, isolationism opposes all commitments to foreign countries including treaties and trade agreements. This distinguishes isolationism from non-interventionism, which also advocates military neutrality but does not necessarily oppose international commitments and treaties in general. This contrasts with philosophies such as colonialism, expansionism, and liberal internationalism. Introduction Isolationism has been defined as: By country Albania Bhutan Before 1999, Bhutan had banned television and the Internet in order to preserve its culture, environment, and identity. Eventually, Jigme Singye Wangchuck lifted the ban on television and the Internet. His son, Jigm ...

Ohio State University
The Ohio State University, commonly called Ohio State or OSU, is a public land-grant research university in Columbus, Ohio. A member of the University System of Ohio, it has been ranked by major institutional rankings among the best public universities in the United States. Founded in 1870 as the state's land-grant university and the ninth university in Ohio with the Morrill Act of 1862, Ohio State was originally known as the Ohio Agricultural and Mechanical College and focused on various agricultural and mechanical disciplines, but it developed into a comprehensive university under the direction of then-Governor and later U.S. president Rutherford B. Hayes, and in 1878, the Ohio General Assembly passed a law changing the name to "the Ohio State University" and broadening the scope of the university. Admission standards tightened and became greatly more selective throughout the 2000s and 2010s. Ohio State's political science department and faculty have greatly contri ...

Radar Altimeter
A radar altimeter (RA), also called a radio altimeter (RALT), electronic altimeter, reflection altimeter, or low-range radio altimeter (LRRA), measures altitude above the terrain presently beneath an aircraft or spacecraft by timing how long it takes a beam of radio waves to travel to ground, reflect, and return to the craft. This type of altimeter provides the distance between the antenna and the ground directly below it, in contrast to a barometric altimeter which provides the distance above a defined vertical datum, usually mean sea level. Principle As the name implies, radar (radio detection and ranging) is the underpinning principle of the system. The system transmits radio waves down to the ground and measures the time it takes them to be reflected back up to the aircraft. The altitude above the ground is calculated from the radio waves' travel time and the speed of light. Radar altimeters required a simple system for measuring the time-of-flight that could be displayed ...
