Nubra River
The Nubra River is a river in the Nubra Valley of Ladakh in India. It is a tributary of the Shyok River (a part of the Indus River system) and originates from the Siachen Glacier, the second-longest non-polar glacier in the world. In earlier Tibetan maps, it was referred as Yarma Tsangpo. Geography The Siachen Glacier terminates in a snout located at around and two pro-glacial melt-water streams originate out of two ice caves in the region. They merge about one kilometer downstream and becomes the Nubra river. Numerous other glaciers of the Karakoram descend into Nubra. It then flows between the Karakoram range and the Saltoro Mountains in a general southeasterly direction for about before its confluence with the Shyok River near Diskit, forming the Nubra Valley. The side valleys of the Nubra Valley contains some 33 glaciers of varying proportions, and the heavy sediment load carried by the river from the melt-water is responsible for many glacio-fluvial deposits including ...

India
India, officially the Republic of India (Hindi: ), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia. Modern humans arrived on the Indian subcontinent from Africa no later than 55,000 years ago., "Y-Chromosome and Mt-DNA data support the colonization of South Asia by modern humans originating in Africa. ... Coalescence dates for most non-European populations average to between 73–55 ka.", "Modern human beings—''Homo sapiens''—originated in Africa. Then, int ...

Populus
''Populus'' is a genus of 25–30 species of deciduous flowering plants in the family Salicaceae, native to most of the Northern Hemisphere. English names variously applied to different species include poplar (), aspen, and cottonwood. The western balsam poplar ('' P. trichocarpa'') was the first tree to have its full DNA code determined by DNA sequencing, in 2006. Description The genus has a large genetic diversity, and can grow from tall, with trunks up to in diameter. The bark on young trees is smooth, white to greenish or dark gray, and often has conspicuous lenticels; on old trees, it remains smooth in some species, but becomes rough and deeply fissured in others. The shoots are stout, with (unlike in the related willows) the terminal bud present. The leaves are spirally arranged, and vary in shape from triangular to circular or (rarely) lobed, and with a long petiole; in species in the sections ''Populus'' and ''Aigeiros'', the petioles are laterally flattened, s ...

Chromium
Chromium is a chemical element with the symbol Cr and atomic number 24. It is the first element in group 6. It is a steely-grey, lustrous, hard, and brittle transition metal. Chromium metal is valued for its high corrosion resistance and hardness. A major development in steel production was the discovery that steel could be made highly resistant to corrosion and discoloration by adding metallic chromium to form stainless steel. Stainless steel and chrome plating (electroplating with chromium) together comprise 85% of the commercial use. Chromium is also greatly valued as a metal that is able to be highly polished while resisting tarnishing. Polished chromium reflects almost 70% of the visible spectrum, and almost 90% of infrared light. The name of the element is derived from the Greek word χρῶμα, ''chrōma'', meaning color, because many chromium compounds are intensely colored. Industrial production of chromium proceeds from chromite ore (mostly FeCr2O4) to produce ferro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cadmium
Cadmium is a chemical element with the symbol Cd and atomic number 48. This soft, silvery-white metal is chemically similar to the two other stable metals in group 12, zinc and mercury. Like zinc, it demonstrates oxidation state +2 in most of its compounds, and like mercury, it has a lower melting point than the transition metals in groups 3 through 11. Cadmium and its congeners in group 12 are often not considered transition metals, in that they do not have partly filled ''d'' or ''f'' electron shells in the elemental or common oxidation states. The average concentration of cadmium in Earth's crust is between 0.1 and 0.5 parts per million (ppm). It was discovered in 1817 simultaneously by Stromeyer and Hermann, both in Germany, as an impurity in zinc carbonate. Cadmium occurs as a minor component in most zinc ores and is a byproduct of zinc production. Cadmium was used for a long time as a corrosion-resistant plating on steel, and cadmium compounds are used as red, orang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cobalt
Cobalt is a chemical element with the symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal. Cobalt-based blue pigments ( cobalt blue) have been used since ancient times for jewelry and paints, and to impart a distinctive blue tint to glass, but the color was for a long time thought to be due to the known metal bismuth. Miners had long used the name ''kobold ore'' (German for ''goblin ore'') for some of the blue-pigment-producing minerals; they were so named because they were poor in known metals, and gave poisonous arsenic-containing fumes when smelted. In 1735, such ores were found to be reducible to a new metal (the first discovered since ancient times), and this was ultimately named for the ''kobold''. Today, some cobalt is produced specifically from one of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biodegradation
Biodegradation is the breakdown of organic matter by microorganisms, such as bacteria and fungi. It is generally assumed to be a natural process, which differentiates it from composting. Composting is a human-driven process in which biodegradation occurs under a specific set of circumstances. The process of biodegradation is threefold: first an object undergoes biodeterioration, which is the mechanical weakening of its structure; then follows biofragmentation, which is the breakdown of materials by microorganisms; and finally assimilation, which is the incorporation of the old material into new cells. In practice, almost all chemical compounds and materials are subject to biodegradation, the key element being time. Things like vegetables may degrade within days, while glass and some plastics take many millennia to decompose. A standard for biodegradability used by the European Union is that greater than 90% of the original material must be converted into , water and minerals b ...

Crevasse
A crevasse is a deep crack, that forms in a glacier or ice sheet that can be a few inches across to over 40 feet. Crevasses form as a result of the movement and resulting stress associated with the shear stress generated when two semi-rigid pieces above a plastic substrate have different rates of movement. The resulting intensity of the shear stress causes a breakage along the faces. Description Crevasses often have vertical or near-vertical walls, which can then melt and create seracs, arches, and other ice formations. These walls sometimes expose layers that represent the glacier's stratigraphy. Crevasse size often depends upon the amount of liquid water present in the glacier. A crevasse may be as deep as 45 metres and as wide as 20 metres. by |
World Commission On Protected Areas
The World Commission on Protected Areas (WCPA) is one of six commissions of the International Union for Conservation of Nature (IUCN). History In 1948, the IUCN established a Committee on National Parks. Two decades later the IUCN had been asked by the international community to take responsibility for preparing a world list of national parks in keeping with its role as a network to share the world’s knowledge on nature conservation, and in 1960, the IUCN raised the status of the Committee to that of a permanent Commission, with the creation of the Commission on National Parks. In 1996, the World Commission on Protected Areas took on its current name with the approval of the IUCN congress. Organizational structure WCPA is a network of volunteers. Secretariat support is provided by staff of the IUCN Programme on Protected Areas, with whom WCPA implements a shared strategic plan and work plan. The Commission has a Steering Committee, and the Chair is elected every four years ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siachen Conflict
The Siachen conflict, sometimes referred to as the Siachen Glacier conflict or the Siachen War, was a military conflict between India and Pakistan over the disputed Siachen Glacier region in Kashmir. The conflict was started in 1984 by India's successful capture of the Siachen Glacier as part of Operation Meghdoot, and continued with Operation Rajiv in 1987. India took control of the Siachen Glacier and its tributary glaciers, as well as all the main passes and heights of the Saltoro Ridge immediately west of the glacier, including Sia La, Bilafond La, and Gyong La. Pakistan controls the glacial valleys immediately west of the Saltoro Ridge. A cease-fire went into effect in 2003, but both sides maintain a heavy military presence in the area. The conflict has resulted in thousands of deaths, mostly due to natural hazards. External commentators of have characterized it as pointless, given the perceived uselessness of the territory, and indicative of bitter stubbornness on both ...

Gyong La
Gyong La is a mountain pass situated on Saltoro Ridge southwest of the vast Siachen Glacier, some directly north of map point NJ9842 which defined the end of the 1972 Line of Control between India and Pakistan. With Pakistan controlling areas just to the west along Chumik Glacier, the immediate Gyong La area has been under India's control since 1989. Dozens of Indian military tents and other equipment are visible in 2013 and 2016 Google Earth imagery 100 meters east, 670 meters northeast, and 2.7 km east-northeast of Gyong La, linked by clear trails. Nearer the former Pakistani "Naveed Top" position and 3.85 km west-northwest of Gyong La is a post and helipad is visible in 2001 and 2016 Google Earth imagery at elevation, higher than both the Indian positions and Gyong La.

Bilafond La
Bilafond La (meaning "Pass of the Butterflies" in Balti language, also known as the Saltoro Pass, is a mountain pass situated on Saltoro Ridge, sitting immediately west of the vast Siachen Glacier, some directly north of map point NJ 980420 which defined the end of the 1972 Line of Control between Pakistan and India as part of the Simla Agreement. Bilafond La is on the ancient Silk Route linking the Indian Subcontinent and China. Bilafond La was a prominent feature during the 1984 start of military action in the Siachen Conflict between India and Pakistan. The Indian Army captured the pass in 1984 along with Sia La to the north and, in 1987, Gyong La to the south. India currently maintains a fortified military base at Bilafond La. Geopolitical issues Bilafond Pass, as well as nearby passes Sia La and Gyong La, were scenes of military activity starting in 1984 during Operation Meghdoot, part of the Siachen Conflict, itself being part of the larger Kashmir Conflict.

Sia La
Sia La is a mountain pass situated on Saltoro Ridge, in Ladakh, India, some north-northwest of map point NJ9842 which defined the end of the 1972 Line of Control between India and Pakistan as part of the Simla Agreement. Sia La sits near the Chinese border and immediately northwest of the upper part of the vast Siachen Glacier, connecting that glacier to the Pakistani-controlled Kondus Glacier and valley to the west. Geopolitical issues Sia La, as well as nearby passes Bilafond La and Gyong La, saw military action starting in 1984 during Operation Meghdoot, the first military action of the Siachen conflict, itself being part of larger conflict, the Kashmir conflict. All three passes are currently held by India; However, Pakistan controls a pass just to the west that overlooks Sia La. They call it Conway Saddle & Leghari OP.
