Alexander Kellas
Alexander Mitchell Kellas (21 June 1868 – 5 June 1921) was a British chemist, explorer, and mountaineer known for his studies of high-altitude physiology. Biography Kellas was born in Aberdeen, Scotland on 21 June 1868.Jill Neate, ''High Asia: An illustrated guide to the 7,000 metre peaks'', The Mountaineers, 1989, . Himalayan Club Vice President Meher Mehta characterized Kellas' papers ''A Consideration of the Possibility of Ascending the Loftier Himalaya'' and ''A Consideration of the Possibility of Ascending Mt Everest'' as "key catalysts in driving scientific thinking into climbing big peaks. His studies included the physiology of acclimatization in relationship to important variables like altitude, barometric pressures, alveolar PO2, arterial oxygen saturation, maximum oxygen consumption, and ascent rates at different altitudes. He had concluded that Mount Everest could be ascended by men of extreme physical and mental constitution without supplementary oxygen if the ...

Aberdeen, Scotland
Aberdeen ( ; ; ) is a port city in North East Scotland, and is the third most populous Scottish city. Historically, Aberdeen was within the historic county of Aberdeenshire, but is now separate from the council area of Aberdeenshire. Aberdeen City Council is one of Scotland's 32 local authorities (commonly referred to as ''councils''). Aberdeen has a population of for the main urban area and for the wider settlement including outlying localities, making it the United Kingdom's 39th most populous built-up area. Aberdeen has a long, sandy coastline and features an oceanic climate, with cool summers and mild, rainy winters. Aberdeen received royal burgh status from David I of Scotland (1124–1153), which transformed the city economically. The traditional industries of fishing, paper-making, shipbuilding, and textiles have been overtaken by the oil industry and Aberdeen's seaport. Aberdeen Heliport is one of the busiest commercial heliports in the world, and the seaport ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It marks the origin of the Teesta River. First ascent Pauhunri has an elevation of and was first climbed in 1911 by Scottish mountaineer, Alexander Mitchell Kellas, along with two Sherpas known only as "Sony" and "Tuny’s brother". Unknown at the time, it was revealed 80 years later that this climb made Pauhunri the highest climbed summit on Earth from 1911 to 1930.

High-altitude Physiology Researchers
Altitude is a distance measurement, usually in the vertical or "up" direction, between a reference datum and a point or object. The exact definition and reference datum varies according to the context (e.g., aviation, geometry, geographical survey, sport, or atmospheric pressure). Although the term ''altitude'' is commonly used to mean the height above sea level of a location, in geography the term elevation is often preferred for this usage. In aviation, altitude is typically measured relative to mean sea level or above ground level to ensure safe navigation and flight operations. In geometry and geographical surveys, altitude helps create accurate topographic maps and understand the terrain's elevation. For high-altitude trekking and sports, knowing and adapting to altitude is vital for performance and safety. Higher altitudes mean reduced oxygen levels, which can lead to altitude sickness if proper acclimatization measures are not taken. Vertical distance measurements in t ...

Kabru
Kabru is a mountain in the Himalayas on the border of eastern Nepal and India. It is part of a ridge that extends south from the third highest mountain in the world Kangchenjunga, and is the southernmost peak in the world. The main features of this ridge are as follows (north to south): * Kangchenjunga South top, 8476 m, at * A 6600–6700 m saddle, located at * A 7349 m summit, known as Talung, at * A 6983 m saddle, at * A 7412 m summit, at . This point has sufficient prominence to be classified as the highest point of a separate mountain, according to the definition used in List of highest mountains. It is confusingly referred to by some authorities as "Kabru IV", but it is not clear that this is correct, or that any "Kabru" name is correctly applied to this summit. * A substantial "field of firn" measuring about 2 km from north to south, and 1 km from east to west. This is almost entirely over 7200 m, and the watershed divide that runs through this field doe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1921 British Mount Everest Reconnaissance Expedition
The 1921 British Mount Everest reconnaissance expedition set off to explore how it might be possible to get to the vicinity of Mount Everest, to reconnoitre possible routes for ascending the mountain, and – if possible – make the first ascent of the highest mountain in the world. At that time Nepal was closed to foreigners, so any approach had to be from the north, through Tibet. A feasible route was discovered from the east up the Kharta Glacier and then crossing the Lhakpa La pass north east of Everest. It was then necessary to descend to the East Rongbuk Glacier before climbing again to Everest's North Col. However, although the North Col was reached, it was not possible to climb further before the expedition had to withdraw. Initially the expedition explored from the north and discovered the main Rongbuk Glacier, only to find that it seemed to provide no likely routes to the summit. However, at the time it was not realised that the East Rongbuk glacier actually flowe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myocardial Infarction
A myocardial infarction (MI), commonly known as a heart attack, occurs when Ischemia, blood flow decreases or stops in one of the coronary arteries of the heart, causing infarction (tissue death) to the heart muscle. The most common symptom is retrosternal Angina, chest pain or discomfort that classically radiates to the left shoulder, arm, or jaw. The pain may occasionally feel like heartburn. This is the dangerous type of acute coronary syndrome. Other symptoms may include shortness of breath, nausea, presyncope, feeling faint, a diaphoresis, cold sweat, Fatigue, feeling tired, and decreased level of consciousness. About 30% of people have atypical symptoms. Women more often present without chest pain and instead have neck pain, arm pain or feel tired. Among those over 75 years old, about 5% have had an MI with little or no history of symptoms. An MI may cause heart failure, an Cardiac arrhythmia, irregular heartbeat, cardiogenic shock or cardiac arrest. Most MIs occur d ...

Lenin Peak
Lenin Peak or Ibn Sina (Avicenna) Peak (, ; ; , renamed () in July 2006 (Tajik); for Russian tex .), rises to in Gorno-Badakhshan (GBAO) on the Kyrgyzstan–Tajikistan border, and is the second-highest point of both countries. It is considered one of the less technical 7,000 m peaks in the world to climb and it has by far the most ascents of any 7,000 m or higher peak on Earth, with every year seeing hundreds of mountaineers make their way to the summit. Lenin Peak is the highest mountain in the Trans-Alay Range of Central Asia, and in the Pamir Mountains in Tajikistan it is exceeded only by Ismoil Somoni Peak (7,495 m). It was thought to be the highest point in the Pamirs in Tajikistan until 1933, when Ismoil Somoni Peak (known as ''Stalin Peak ...
