Onge People
The Onge (also Önge, Ongee, and Öñge) are an Andamanese ethnic group, indigenous to the Andaman Islands in Southeast Asia at the Bay of Bengal, currently administered by India. They are traditionally hunter-gatherers and fishers, but also practice plant cultivation. They are designated as a Scheduled Tribe of India. History In the 18th century the Onge, or Madhumitha, were distributed across Little Andaman Island and the nearby islands, with some territory and camps established on Rutland Island and the southern tip of South Andaman Island. After they encountered British colonial officers, friendly relations were established with the British Empire in the 1800s through Lieutenant Archibald Blair. British naval officer M. V. Portman described them as the "mildest, most timid, and inoffensive" group of Andamanese people he had encountered. By the end of the 19th century they sometimes visited the South and North Brother Islands to catch sea turtles; at the time, those ...

Ethanol
Ethanol (abbr. EtOH; also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound. It is an Alcohol (chemistry), alcohol with the chemical formula . Its formula can be also written as or (an ethyl group linked to a hydroxyl group). Ethanol is a Volatility (chemistry), volatile, Combustibility and flammability, flammable, colorless liquid with a characteristic wine-like odor and pungent taste. It is a psychoactive recreational drug, the active ingredient in alcoholic drinks. Ethanol is naturally produced by the fermentation process of Carbohydrate, sugars by yeasts or via Petrochemistry, petrochemical processes such as ethylene hydration. It has medical applications as an antiseptic and disinfectant. It is used as a chemical solvent and in the Chemical synthesis, synthesis of organic compounds, and as a Alcohol fuel, fuel source. Ethanol also can be dehydrated to make ethylene, an important chemical feedstock. As of 2006, world produ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Methanol
Methanol (also called methyl alcohol and wood spirit, amongst other names) is an organic chemical and the simplest aliphatic alcohol, with the formula C H3 O H (a methyl group linked to a hydroxyl group, often abbreviated as MeOH). It is a light, volatile, colourless, flammable liquid with a distinctive alcoholic odour similar to that of ethanol (potable alcohol). A polar solvent, methanol acquired the name wood alcohol because it was once produced chiefly by the destructive distillation of wood. Today, methanol is mainly produced industrially by hydrogenation of carbon monoxide. Methanol consists of a methyl group linked to a polar hydroxyl group. With more than 20 million tons produced annually, it is used as a precursor to other commodity chemicals, including formaldehyde, acetic acid, methyl tert-butyl ether, methyl benzoate, anisole, peroxyacids, as well as a host of more specialised chemicals. Occurrence Small amounts of methanol are present in normal, healthy hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cultural Survival Quarterly
Cultural Survival (founded 1972) is a nonprofit group based in Cambridge, Massachusetts, United States, which is dedicated to defending the human rights of indigenous peoples. History Cultural Survival was founded by anthropologist David Maybury-Lewis and his wife, Pia, in response to the opening up of the Amazonian and South American hinterlands during the 1960s, and the drastic effects this had on Indigenous inhabitants. It has since worked with Indigenous communities in Asia, Africa, South America, North America, and Australia, becoming the leading US-based organization defending the rights of Indigenous Peoples around the world. Headquartered in Cambridge, Massachusetts, Cultural Survival also has a satellite office for the Guatemala Radio Project in Guatemala. As of 2022, Cultural Survival had a four-star rating from Charity Navigator.

2004 Indian Ocean Earthquake
An earthquake and a tsunami, known as the Boxing Day Tsunami and, by the scientific community, the Sumatra–Andaman earthquake, occurred at 07:58:53 local time (UTC+7) on 26 December 2004, with an epicentre off the west coast of northern Sumatra, Indonesia. It was an undersea megathrust earthquake that registered a magnitude of 9.1–9.3 , reaching a Mercalli intensity up to IX in certain areas. The earthquake was caused by a rupture along the fault between the Burma Plate and the Indian Plate. A series of massive tsunami waves grew up to high once heading inland, after being created by the underwater seismic activity offshore. Communities along the surrounding coasts of the Indian Ocean were devastated, and the tsunamis killed an estimated 227,898 people in 14 countries, making it one of the deadliest natural disasters in recorded history. The direct results caused major disruptions to living conditions and commerce in coastal provinces of surrounded countries, including Ac ...

Tsunami
A tsunami ( ; from ja, 津波, lit=harbour wave, ) is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions (including detonations, landslides, glacier calvings, meteorite impacts and other disturbances) above or below water all have the potential to generate a tsunami. Unlike normal ocean waves, which are generated by wind, or tides, which are in turn generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water from a large event. Tsunami waves do not resemble normal undersea currents or sea waves because their wavelength is far longer. Rather than appearing as a breaking wave, a tsunami may instead initially resemble a rapidly rising tide. For this reason, it is often referred to as a tidal wave, although this usage is not favoured by the scientific community because it might give ...

Net Reproductive Index
In population ecology and demography, the net reproduction rate, ''R''0, is the average number of offspring (often specifically daughters) that would be born to a female if she passed through her lifetime conforming to the age-specific fertility and mortality rates of a given year. This rate is similar to the gross reproduction rate but takes into account that some females will die before completing their childbearing years. An ''R''0 of one means that each generation of mothers is having exactly enough daughters to replace themselves in the population. If the R0 is less than one, the reproductive performance of the population is below replacement level. The ''R''0 is particularly relevant where sex ratios at birth are significantly affected by the use of reproductive technologies, or where life expectancy is low. The current (2015–20) estimate for the R0 worldwide under the UN's medium variant model is 1.09 daughters per woman. See also *List of countries by net reproduction ...

Great Andamanese People
The Great Andamanese are an indigenous people of the Great Andaman archipelago in the Andaman Islands. Historically, the Great Andamanese lived throughout the archipelago, and were divided into ten major tribes. Their distinct but closely related languages comprised the Great Andamanese languages, one of the two identified Andamanese language families. The Great Andamanese were clearly related to the other Andamanese peoples, but were well separated from them by culture and geography. The languages of those other four groups were only distantly related to those of the Great Andamanese and mutually unintelligible; they are classified in a separate family, the Ongan languages. They were once the most numerous of the five major groups in the Andaman Islands with an estimated population between 2,000 and 6,600, the Great Andamanese were heavily decimated by diseases, alcohol, colonial warfare and loss of hunting territory. Only 52 remained as of February 2010; by August 2020 there ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Turtle
Sea turtles (superfamily Chelonioidea), sometimes called marine turtles, are reptiles of the order Testudines and of the suborder Cryptodira. The seven existing species of sea turtles are the flatback, green, hawksbill, leatherback, loggerhead, Kemp's ridley, and olive ridley sea turtles. All six of the sea turtle species present in US waters (all of those listed above except the flatback) are listed as endangered and/or threatened under the Endangered Species Act. The seventh sea turtle species is the flatback, which exists in the waters of Australia, Papua New Guinea and Indonesia. Sea turtles can be separated into the categories of hard-shelled (cheloniid) and leathery-shelled ( dermochelyid).Wyneken, J. 2001. The Anatomy of Sea Turtles. U.S Department of Commerce NOAA Technical Memorandum NMFS-SEFSC-470, 1-172 pp. There is only one dermochelyid species which is the leatherback sea turtle.
