Beck Weathers
Seaborn Beck Weathers (born December 16, 1946) is an American pathologist from Texas. He survived the 1996 Mount Everest disaster, which was covered in Jon Krakauer's book ''Into Thin Air'' (1997), its film adaptation '' Into Thin Air: Death on Everest'' (1997), and the films ''Everest'' (1998) and ''Everest'' (2015). His autobiographical book, titled ''Left for Dead: My Journey Home from Everest'' (2000) includes his ordeal, but also describes his life before and afterward, as he focused on saving his damaged relationships. Early life and personal life Weathers was born in a military family. He attended college in Wichita Falls, Texas, married, and had two children. In 1986, he enrolled in a mountaineering course and later decided to try to climb the Seven Summits. He considered Richard Bass, the first man to climb the Seven Summits, an "inspiration" who made summitting Everest seem possible for "regular guys". In 1993, he was making a guided ascent on Vinson Massif, where he enco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pathology
Pathology is the study of the causes and effects of disease or injury. The word ''pathology'' also refers to the study of disease in general, incorporating a wide range of biology research fields and medical practices. However, when used in the context of modern medical treatment, the term is often used in a narrower fashion to refer to processes and tests that fall within the contemporary medical field of "general pathology", an area which includes a number of distinct but inter-related medical specialties that diagnose disease, mostly through analysis of tissue, cell, and body fluid samples. Idiomatically, "a pathology" may also refer to the predicted or actual progression of particular diseases (as in the statement "the many different forms of cancer have diverse pathologies", in which case a more proper choice of word would be " pathophysiologies"), and the affix ''pathy'' is sometimes used to indicate a state of disease in cases of both physical ailment (as in cardiomy ...

Effects Of High Altitude On Humans
The effects of high altitude on humans are mostly the consequences of reduced partial pressure of oxygen in the atmosphere. The oxygen saturation of hemoglobin determines the content of oxygen in blood. After the human body reaches around above sea level, the saturation of oxyhemoglobin begins to decrease rapidly. However, the human body has both short-term and long-term adaptations to altitude that allow it to partially compensate for the lack of oxygen. There is a limit to the level of adaptation; mountaineers refer to the altitudes above as the death zone, where it is generally believed that no human body can acclimatize. At extreme altitudes, the ambient pressure can drop below the vapor pressure of water at body temperature, but at such altitudes even pure oxygen at ambient pressure cannot support human life, and a pressure suit is necessary. A rapid depressurisation to the low pressures of high altitudes can trigger altitude decompression sickness. Effects as a function ...

Medical City Dallas Hospital
Medical City Dallas is a hospital located at 7777 Forest Lane, just west of North Central Expressway (US 75), in north Dallas, Texas (USA). It is operated by Hospital Corporation of America History Medical City opened its doors after Dr. Frank Seay cut the ribbon that opened Medical City Dallas Hospital to the residents of the community on October 2, 1974. Developer Trammell Crow and his partners chose to locate the hospital and medical office tower on a 250-acre plot in the Park Central area of Dallas partly because preliminary research showed that as of 1972 when the development was planned, 85 percent of all MDs in Dallas County lived within 15 minutes'driving of the new complex.(Unnamed author.) "Medical City Dallas will be strictly '20th century'," ''The Dallas Morning News'', 30 April 1972, page 14. Retrieved from NewsBank 30 April 2016. Estimates of the cost at the announcement of the project on April 6, 1972, were that the complex would cost $20 million(Unnamed author.) ...

Dallas, Texas
Dallas () is the third largest city in Texas and the largest city in the Dallas–Fort Worth metroplex, the fourth-largest metropolitan area in the United States at 7.5 million people. It is the largest city in and seat of Dallas County with portions extending into Collin, Denton, Kaufman and Rockwall counties. With a 2020 census population of 1,304,379, it is the ninth most-populous city in the U.S. and the third-largest in Texas after Houston and San Antonio. Located in the North Texas region, the city of Dallas is the main core of the largest metropolitan area in the Southern United States and the largest inland metropolitan area in the U.S. that lacks any navigable link to the sea. The cities of Dallas and nearby Fort Worth were initially developed due to the construction of major railroad lines through the area allowing access to cotton, cattle and later oil in North and East Texas. The construction of the Interstate Highway System reinforced Dallas's prominen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plastic Surgery
Plastic surgery is a surgical specialty involving the restoration, reconstruction or alteration of the human body. It can be divided into two main categories: reconstructive surgery and cosmetic surgery. Reconstructive surgery includes craniofacial surgery, hand surgery, microsurgery, and the treatment of burns. While reconstructive surgery aims to reconstruct a part of the body or improve its functioning, cosmetic (or aesthetic) surgery aims at improving the appearance of it. Etymology The word ''plastic'' in ''plastic surgery'' means "reshaping" and comes from the Greek πλαστική (τέχνη), ''plastikē'' (''tekhnē''), "the art of modelling" of malleable flesh. This meaning in English is seen as early as 1598. The surgical definition of "plastic" first appeared in 1839, preceding the modern "engineering material made from petroleum" sense by 70 years. History Treatments for the plastic repair of a broken nose are first mentioned in the Egyptian medical text ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amputation
Amputation is the removal of a limb by trauma, medical illness, or surgery. As a surgical measure, it is used to control pain or a disease process in the affected limb, such as malignancy or gangrene. In some cases, it is carried out on individuals as a preventive surgery for such problems. A special case is that of congenital amputation, a congenital disorder, where fetal limbs have been cut off by constrictive bands. In some countries, amputation is currently used to punish people who commit crimes. Amputation has also been used as a tactic in war and acts of terrorism; it may also occur as a war injury. In some cultures and religions, minor amputations or mutilations are considered a ritual accomplishment. When done by a person, the person executing the amputation is an amputator. The oldest evidence of this practice comes from a skeleton found buried in Liang Tebo cave, East Kalimantan, Indonesian Borneo dating back to at least 31,000 years ago, where it was done when ...

Western Cwm
The Western Cwm () is a broad, flat, gently undulating glacial valley basin terminating at the foot of the Lhotse Face of Mount Everest. It was named by George Mallory when he saw it in 1921 as part of the British Reconnaissance Expedition that was the first to explore the upper sections of Everest, searching for routes for future summit attempts; p. 7 Cwm is Welsh for "valley". The Western Cwm is traversed by climbers using the southeast route to the summit of Everest and is typically accessed by climbing through the Khumbu Icefall. The central section is cut by massive lateral crevasses which bar entrance into the upper Western Cwm. In this section, climbers must cross to the far right, over to the base of Nuptse, to a narrow passageway known as the Nuptse corner. From there, climbers can see the upper of Everest—the first glimpse of Everest's upper slopes since arriving at Base Camp. The snow-covered, bowl-shaped slopes surrounding the Western Cwm reflect and amplify sola ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most comm ...

Medical Evacuation
Medical evacuation, often shortened to medevac or medivac, is the timely and efficient movement and en route care provided by medical personnel to wounded being evacuated from a battlefield, to injured patients being evacuated from the scene of an accident to receiving medical facilities, or to patients at a rural hospital requiring urgent care at a better-equipped facility using medically equipped air ambulances, especially helicopters. Examples include civilian EMS vehicles, civilian aeromedical helicopter services, and military air ambulances. This term also covers the transfer of patients from the battlefield to a treatment facility or from one treatment facility to another by medical personnel, such as from a local hospital to a trauma center. History The first medical transport by air was recorded in Serbia in the autumn of 1915 during First World War. One of the ill soldiers in that first medical transport was Milan Rastislav Štefánik, a Slovak pilot-volunteer who was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porcelain
Porcelain () is a ceramic material made by heating substances, generally including materials such as kaolinite, in a kiln to temperatures between . The strength and translucence of porcelain, relative to other types of pottery, arises mainly from vitrification and formation of the mineral mullite within the body at these high temperatures. Though definitions vary, porcelain can be divided into three main categories: hard-paste, soft-paste, and bone china. The category that an object belongs to depends on the composition of the paste used to make the body of the porcelain object and the firing conditions. Porcelain slowly evolved in China and was finally achieved (depending on the definition used) at some point about 2,000 to 1,200 years ago; it slowly spread to other East Asian countries, then to Europe, and eventually to the rest of the world. Its manufacturing process is more demanding than that for earthenware and stoneware, the two other main types of pottery, and it ...

Bivouac Shelter
A bivouac shelter is any of a variety of improvised camp site, or shelter that is usually of a temporary nature, used especially by soldiers, or people engaged in backpacking, bikepacking, scouting, or mountain climbing. It may often refer to sleeping in the open with a bivouac sack, but it may also refer to a shelter constructed of natural materials like a structure of branches to form a frame, which is then covered with leaves, ferns, and similar material for waterproofing and duff (leaf litter) for insulation. Modern bivouacs often involve the use of one- or two-man tents but may also be without tents or full cover. In modern mountaineering the nature of the bivouac shelter will depend on the level of preparedness, in particular whether existing camping and outdoor gear may be incorporated into the shelter. A bivouac shelter is colloquially known as a bivvy (also spelled ''bivy'' or ''bivvi'' or ''bivi''). Etymology The word ''bivouac'' is French and ultimately derives from a ...

Yasuko Namba
was the second Japanese woman (after Junko Tabei) to reach all of the Seven Summits. Namba worked as a businesswoman for Federal Express in Japan, but her hobby of mountaineering took her all over the world. She first summited Kilimanjaro on New Year's Day in 1982, and summited Aconcagua exactly two years later. She reached the summit of Denali on July 1, 1985, and the summit of Mount Elbrus on August 1, 1992. After summiting the Vinson Massif on December 29, 1993, and the Carstensz Pyramid on November 12, 1994, Namba's final summit to reach was Mount Everest. She signed on with Rob Hall's guiding company, Adventure Consultants, and reached the summit in May 1996, but died during her descent in the 1996 Mount Everest disaster. Personal and professional life Prior to her involvement in the Everest disaster, Yasuko Namba had been employed by Federal Express as a personnel manager in Tokyo, Japan. She was survived by her husband, Kenichi Namba, and her brother, both of whom lat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
