Stowaways
A stowaway or clandestine traveller is a person who secretly boards a vehicle, such as a ship, an aircraft, a train, cargo truck or bus. Sometimes, the purpose is to get from one place to another without paying for transportation. In other cases, the goal is to enter another country without first obtaining a travel visa or other permission. Stowaways differ from people smuggling in that the stowaway needs to avoid detection by the truck driver, ship crew, and others responsible for the safe and secure operation of the transportation service. Thousands of stowaways have travelled by sea or land over the last several centuries. A much smaller number of people have attempted to stowaway on aircraft. Many stowaways have died during the attempt, especially in cases of train surfing and wheel-well stowaway flights. Origin The word takes its origin with the expression ''stow away''. This ''stow away'' expression is old and was used for things (such as food), such usage is seen for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Wheel-well Stowaway Flights
Wheel-well stowaways are people who attempt to travel in the landing gear compartment, also known as the wheel bay or undercarriage of an aircraft. Between 1947 and June 2015, a U.S. Federal Aviation Administration (FAA) researcher had documented 113 such attempts on 101 flights. These 113 people were all male and predominantly under age 30. There were 86 deaths, a 76 percent fatality rate,MotherboardThe Science of Stowing Away in an Airplane June 20, 2015 with many unidentified decedents. There may be additional undocumented cases of wheel-well stowaways. A further 19 incidents, identified since 2015, are listed here. Wheel-well stowaways face considerable risk of death during all phases of flight. Some have been unable to remain in the well during takeoff and landing and have fallen to their death. Immediately after takeoff, the landing gear retracts into the wheel wells, with the potential to crush the stowaway.USA TodayFAA: Most plane stowaways in wheel well die April 21, 2014 ...

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and wat ...

Astrakhan Trams, 1041 Stowaway
Astrakhan ( rus, Астрахань, p=ˈastrəxənʲ) is the largest city and administrative centre of Astrakhan Oblast in Southern Russia. The city lies on two banks of the Volga, in the upper part of the Volga Delta, on eleven islands of the Caspian Depression, 60 miles (100 km) from the Caspian Sea, with a population of 475,629 residents at the 2021 Census. At an elevation of below sea level, it is the lowest city in Russia. Astrakhan was formerly the capital of the Khanate of Astrakhan (a remnant of the Golden Horde), and was located on the higher right bank of the Volga, 7 miles (11 km) from the present-day city. Situated on caravan and water routes, it developed from a village into a large trading centre, before being conquered by Timur in 1395 and captured by Ivan the Terrible in 1556. In 1558 it was moved to its present site. The oldest economic and cultural center of the Lower Volga, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jan Valtin
Richard Julius Hermann Krebs (December 17, 1905 - January 1, 1951), better known by his alias Jan Valtin, was a German writer during the interwar period. He settled in the United States in 1938, and in 1940 (as Valtin) wrote his bestselling book ''Out of the Night''. Background Krebs became active in the Communist movement as a boy, when his father was involved in the naval mutiny that heralded the German Revolution of 1918–19. Career In 1923, he saw action in the failed Communist insurgency in Hamburg. Sometime after this he joined the German Communist Party, but was later expelled. Arrest In 1926, Krebs entered the United States illegally and moved to California. He spent 38 months in San Quentin State Prison for attempting to murder a merchant navy seaman during a brawl, then was deported to Germany in 1929. He worked as a seaman until 1934, when he was arrested and tortured, and acted as a witness for prosecution in a trial that brought to the conviction of a fellow ...

Tremor
A tremor is an involuntary, somewhat rhythmic, muscle contraction and relaxation involving oscillations or twitching movements of one or more body parts. It is the most common of all involuntary movements and can affect the hands, arms, eyes, face, head, vocal folds, trunk, and legs. Most tremors occur in the hands. In some people, a tremor is a symptom of another neurological disorder. A very common tremor is the teeth chattering, usually induced by cold temperatures or by fear. Types Tremor is most commonly classified by clinical features and cause or origin. Some of the better-known forms of tremor, with their symptoms, include the following: * Cerebellar tremor (also known as intention tremor) is a slow, broad tremor of the extremities that occurs at the end of a purposeful movement, such as trying to press a button or touching a finger to the tip of one's nose. Cerebellar tremor is caused by lesions in or damage to the cerebellum resulting from stroke, tumor, or disease such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vision Impairment
Visual impairment, also known as vision impairment, is a medical definition primarily measured based on an individual's better eye visual acuity; in the absence of treatment such as correctable eyewear, assistive devices, and medical treatment– visual impairment may cause the individual difficulties with normal daily tasks including reading and walking. Low vision is a functional definition of visual impairment that is chronic, uncorrectable with treatment or correctable lenses, and impacts daily living. As such low vision can be used as a disability metric and varies based on an individual's experience, environmental demands, accommodations, and access to services. The American Academy of Ophthalmology defines visual impairment as the best-corrected visual acuity of less than 20/40 in the better eye, and the World Health Organization defines it as a presenting acuity of less than 6/12 in the better eye. The term blindness is used for complete or nearly complete vision loss. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lightheadedness
Lightheadedness is a common and typically unpleasant sensation of dizziness or a feeling that one may faint. The sensation of lightheadedness can be short-lived, prolonged, or, rarely, recurring. In addition to dizziness, the individual may feel as though their head is weightless. The individual may also feel as though the room is "spinning" or moving (vertigo). Most causes of lightheadedness are not serious and either cure themselves quickly, or are easily treated. Keeping a sense of balance requires the brain to process a variety of information received from the eyes, the nervous system, and the inner ears. If the brain is unable to process these signals, such as when the messages are contradictory, or if the sensory systems are improperly functioning, an individual may experience lightheadedness or dizziness. Lightheadedness is very similar to pre-syncope. Pre-syncope is the immediate stage before syncope (fainting), particularly in cases of temporary visual field loss (i.e. ...

Acidosis
Acidosis is a process causing increased acidity in the blood and other body tissues (i.e., an increase in hydrogen ion concentration). If not further qualified, it usually refers to acidity of the blood plasma. The term ''acidemia'' describes the state of low blood pH, while ''acidosis'' is used to describe the processes leading to these states. Nevertheless, the terms are sometimes used interchangeably. The distinction may be relevant where a patient has factors causing both acidosis and alkalosis, wherein the relative severity of both determines whether the result is a high, low, or normal pH. Acidemia is said to occur when arterial pH falls below 7.35 (except in the fetus – see below), while its counterpart ( alkalemia) occurs at a pH over 7.45. Arterial blood gas analysis and other tests are required to separate the main causes. The rate of cellular metabolic activity affects and, at the same time, is affected by the pH of the body fluids. In mammals, the normal pH of ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frostbite
Frostbite is a skin injury that occurs when exposed to extreme low temperatures, causing the freezing of the skin or other tissues, commonly affecting the fingers, toes, nose, ears, cheeks and chin areas. Most often, frostbite occurs in the hands and feet. The initial symptoms are typically a feeling of cold and tingling or numbing. This may be followed by clumsiness with a white or bluish color to the skin. Swelling or blistering may occur following treatment. Complications may include hypothermia or compartment syndrome. People who are exposed to low temperatures for prolonged periods, such as winter sports enthusiasts, military personnel, and homeless individuals, are at greatest risk. Other risk factors include drinking alcohol, smoking, mental health problems, certain medications, and prior injuries due to cold. The underlying mechanism involves injury from ice crystals and blood clots in small blood vessels following thawing. Diagnosis is based on symptoms. Severity may ...

Hypoxic Hypoxia
Generalized hypoxia is a medical condition in which the tissues of the body are deprived of the necessary levels of oxygen due to an insufficient supply of oxygen, which may be due to the composition or pressure of the breathing gas, decreased lung ventilation, or respiratory disease, any of which may cause a lower than normal oxygen content in the arterial blood, and consequently a reduced supply of oxygen to all tissues perfused by the arterial blood. This usage is in contradistinction to localized hypoxia, in which only an associated group of tissues, usually with a common blood supply, are affected, usually due to an insufficient or reduced blood supply to those tissues. Genralized hypoxia is also used as a synonym for hypoxic hypoxia This is not to be confused with hypoxemia, which refers to low levels of oxygen in the blood, although the two conditions often occur simultaneously, since a decrease in blood oxygen typically corresponds to a decrease in oxygen in the surroundi ...

Hypothermia
Hypothermia is defined as a body core temperature below in humans. Symptoms depend on the temperature. In mild hypothermia, there is shivering and mental confusion. In moderate hypothermia, shivering stops and confusion increases. In severe hypothermia, there may be hallucinations and paradoxical undressing, in which a person removes their clothing, as well as an increased risk of the heart stopping. Hypothermia has two main types of causes. It classically occurs from exposure to cold weather and cold water immersion. It may also occur from any condition that decreases heat production or increases heat loss. Commonly, this includes alcohol intoxication but may also include low blood sugar, anorexia and advanced age. Body temperature is usually maintained near a constant level of through thermoregulation. Efforts to increase body temperature involve shivering, increased voluntary activity, and putting on warmer clothing. Hypothermia may be diagnosed based on either a person ...
