Api (mountain)

Api is the highest peak in the Yoka Pahar Section of Gurans Himal, part of the Himalayas in the extreme northwest corner of Nepal, near the borders of India and Tibet. It is a little-known peak in a rarely visited part of the Himalayas, but it rises dramatically over the low surrounding terrain.

Notable features

Although low in elevation among the major mountains of Nepal, Api is exceptional in its rise above local terrain; the surrounding valleys are significantly lower than those surrounding most higher Himalayan peaks.

Climbing history

The Api region was visited by Westerners in 1899, 1905, and 1936, but the peak was not attempted until 1953 on a visit by W. H. Murray a Scottish Mountaineer with John Tyson. This attempt was unsuccessful, as was another, by Italians, in 1954 which resulted in the death of two expedition members.

The first ascent of Api occurred in 1960. The Doshisha Alpine Society of Japan successfully completed the Northwest Face route attempted by the 1954 party.

Mountain

A mountain is a large landform that stretches above the surrounding land in a limited area, usually in the form of a peak. A mountain is generally steeper than a hill. Mountains are formed through tectonic forces or volcanism. These forces can locally raise the surface of the earth. Mountains erode slowly through the action of rivers, weather conditions, and glaciers. A few mountains are isolated summits, but most occur in huge mountain ranges.

High elevations on mountains produce colder climates than at sea level. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains tend to be used less for agriculture and more for resource extraction and recreation, such as mountain climbing.

The highest mountain on Earth is Mount Everest in the Himalayas of Asia, whose summit is 8,850 m (29,035 ft) above mean sea level. The highest known mountain on any planet in the Solar System is Olympus Mons on Mars at 21,171 m (69,459 ft).

Sahtu

The Sahtú or North Slavey (historically called Hare or Hareskin Indians) are a Dene First Nations people of the Athabaskan-speaking ethnolinguistic group living in the vicinity of Great Bear Lake (Sahtú, the source of their name), Northwest Territories, Canada. The Sahtú peoples live in Colville Lake, Deline, Fort Good Hope, Norman Wells and Tulita which form the Sahtu Region of the NWT. The Dene of the region are represented by the Sahtu Dene Council who, in 1993, signed the Sahtu Dene and Metis Comprehensive Land Claim Agreement. Sahtú groups include the Hare Dene (K'ahsho Got'ine District, today: Colville Lake and Fort Good Hope), Bear Lake Dene (Déline District), and Mountain Dene (Tulit'a District). They call themselves also Ɂehdzo Got’ı̨ne (Trap People).

Ethnography

An early description of Sahtú cultures is given in Alexander Mackenzie's journal of his voyage down the Mackenzie River to the Arctic Ocean in 1789.

Although there are close interrelationships among the Dene communities, they are culturally and linguistically distinct. The K’ahsho Got’ine (Hare(skin) Dene) are now centred in Fort Good Hope and Colville Lake. The Shita Got’ine (Mountain Dene) have joined with the K’áálǫ Got’ine (Willow Lake Dene) (they lived around K’áálô Tué - ″Willow Lake″, today known as Brackett Lake) in the community of Tulit’a. The Sahtúot’ine (Sahtú Dene or Great Bear Lake Dene) are named after Sahtú/Great Bear Lake, and are based in Deline. Métis people, descendents of relationships established between Dene people and fur traders, reside in all five communities of the region. The Hareskin Dene called themselves K'a so Got’ine/Katoo Got’ine ("big willow people") or K’ahsho Got’ine/K'áshot’ Got’ine (″big-arrowhead-people″, mistranslated as Hareskin people, an English rendering of Gahwié Got’ine - ″Rabbit(skin) People″).

API gravity

The American Petroleum Institute gravity, or API gravity, is a measure of how heavy or light a petroleum liquid is compared to water: if its API gravity is greater than 10, it is lighter and floats on water; if less than 10, it is heavier and sinks.

API gravity is thus an inverse measure of a petroleum liquid's density relative to that of water (also known as specific gravity). It is used to compare densities of petroleum liquids. For example, if one petroleum liquid is less dense than another, it has a greater API gravity. Although mathematically, API gravity is a dimensionless quantity, see the formula below, it is referred to as being in 'degrees'. API gravity is gradated in degrees on a hydrometer instrument. API gravity values of most petroleum liquids fall between 10 and 70 degrees.

History of development

In 1916, the U.S. National Bureau of Standards accepted the Baumé scale, which had been developed in France in 1768, as the U.S. standard for measuring the specific gravity of liquids less dense than water. Investigation by the U.S. National Academy of Sciences found major errors in salinity and temperature controls that had caused serious variations in published values. Hydrometers in the U.S. had been manufactured and distributed widely with a modulus of 141.5 instead of the Baumé scale modulus of 140. The scale was so firmly established that, by 1921, the remedy implemented by the American Petroleum Institute was to create the API gravity scale, recognizing the scale that was actually being used.

6-(2-Aminopropyl)indole

6-(2-Aminopropyl)indole (6-API, 6-IT) is an indole derivative with no history of use in humans. The analogue 5-API is known to be psychoactive, indicating 6-API may also be psychoactive by the same structure-activity relationship that links 5-APB and 6-APB.

Alexander Shulgin says in his book TiHKAL "From the normal 3-position to the 2, the 4, the 5, the 6 or the 7-positions. All five alpha-methyltryptamine isomers are known, but only one is known to be active in man as a CNS active material. This is the 5-isomer, 5-(2-aminopropyl)indole or 5-IT".

Studies in dogs have also shown the drug to increase hemoglobin levels in the bloodstream.

Baculoviral IAP repeat-containing protein 3

Baculoviral IAP repeat-containing protein3 (also known as cIAP2) is a protein that in humans is encoded by the BIRC3 gene.

cIAP2 is a member of the Inhibitor of Apoptosis family that inhibit apoptosis by interfering with the activation of caspases. The encoded protein inhibits apoptosis induced by serum deprivation but does not affect apoptosis resulting from exposure to menadione, a potent inducer of free radicals. The cIAP2 protein contains three BIR domains, a UBA domain, a CARD domain and a RING finger domain. Transcript variants encoding the same isoform have been identified.

Interactions

Baculoviral IAP repeat-containing protein 3 has been shown to interact with:
