Igloo
An igloo (Inuit languages: , Inuktitut syllabics (plural: )), also known as a snow house or snow hut, is a type of shelter built of suitable snow. Although igloos are often associated with all Inuit, they were traditionally used only by the people of Canada's Central Arctic and the Qaanaaq area of Greenland. Other Inuit tended to use snow to insulate their houses, which were constructed from whalebone and hides. Snow is used because the air pockets trapped in it make it an insulator. On the outside, temperatures may be as low as , but on the inside, the temperature may range from when warmed by body heat alone. Nomenclature The Inuit language word (plural ) can be used for a house or home built of any material, and is not restricted exclusively to snowhouses (called specifically , plural ), but includes traditional tents, sod houses, homes constructed of driftwood and modern buildings. Several dialects throughout the Canadian Arctic (Siglitun, Inuinnaqtun, Natsil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Igloolik
Igloolik ( Inuktitut syllabics: , ''Iglulik'', ) is an Inuit hamlet in Foxe Basin, Qikiqtaaluk Region in Nunavut, northern Canada. Because its location on Igloolik Island is close to Melville Peninsula, it is often mistakenly thought to be on the peninsula. The name "Igloolik" means "there is a house here". It derives from meaning house or building, and refers to the sod houses that were originally in the area, not to snow igloos. In Inuktitut the residents are called Iglulingmiut (the suffix ''miut'' means "people of"). History Information about the area’s earliest inhabitants comes mainly from numerous archaeological sites on the island; some dating back more than 4,000 years. First contact with Europeans came when British Navy ships HMS ''Fury'' and HMS ''Hecla'', under the command of Captain William Edward Parry, wintered in Igloolik in 1822. The island was visited in 1867 and 1868 by the American explorer Charles Francis Hall in his search for survivors of the lost ...

Inuit
Inuit (; iu, ᐃᓄᐃᑦ 'the people', singular: Inuk, , dual: Inuuk, ) are a group of culturally similar indigenous peoples inhabiting the Arctic and subarctic regions of Greenland, Labrador, Quebec, Nunavut, the Northwest Territories, and Alaska. Inuit languages are part of the Eskimo–Aleut languages, also known as Inuit-Yupik-Unangan, and also as Eskaleut. Inuit Sign Language is a critically endangered language isolate used in Nunavut. Inuit live throughout most of Northern Canada in the territory of Nunavut, Nunavik in the northern third of Quebec, Nunatsiavut and NunatuKavut in Labrador, and in various parts of the Northwest Territories, particularly around the Arctic Ocean, in the Inuvialuit Settlement Region. With the exception of NunatuKavut, these areas are known, primarily by Inuit Tapiriit Kanatami, as Inuit Nunangat. In Canada, sections 25 and 35 of the Constitution Act of 1982 classify Inuit as a distinctive group of Aboriginal Canadians wh ...

Netsilik Inuit
The Netsilik (Netsilingmiut) are Inuit who live predominantly in Kugaaruk and Gjoa Haven of the Kitikmeot Region, Nunavut and to a smaller extent in Taloyoak and the north Qikiqtaaluk Region, in Canada. They were, in the early 20th century, among the last northern indigenous peoples to encounter missionaries from the south. Language The missionaries introduced a system of written language called Qaniujaaqpait, based on syllabics, to the Netsilik in the 1920s. Eastern Canadian Inuit, among them the Netsilik, were the only Inuit to adopt a syllabic system of writing. The Netsilik's spoken language is ''Natsilingmiutut''. The Utkuhiksalingmiut, a Caribou Inuit band, speak a variant of it, Utkuhiksalik. Hunting and fishing The harsh Arctic environment that the Netsilik inhabited yielded little plant life, so the Netsilik had to rely on hunting to acquire most of the resources they needed to survive. In the summer months, the Netsilik would hunt caribou on the tundra. The car ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kudlik
The qulliq (seal-oil, blubber or soapstone lamp, iu, ᖁᓪᓕᖅ, ''kudlik'' ; ik, naniq), is the traditional oil lamp used by Arctic peoples, including the Inuit, the Chukchi and the Yupik peoples. This characteristic type of oil lamp provided warmth and light in the harsh Arctic environment where there was no wood and where the sparse inhabitants relied almost entirely on seal oil or on whale blubber. This lamp was the single most important article of furniture for the Inuit in their dwellings. History It is uncertain in which period the seal-oil lamps began to be used. They are part of a series of technological innovations among the Arctic peoples whose introduction and spread has been partly documented. Oil lamps have been found in sites of Paleo-Eskimo communities dating back to the time of the Norton tradition, 3,000 years ago. They were a common implement of the Dorset culture and of the Thule people, the lamps manufactured then showing little changes compared ...

Cold Trap
In vacuum applications, a cold trap is a device that condenses all vapors except the permanent gases into a liquid or solid. The most common objective is to prevent vapors being evacuated from an experiment from entering a vacuum pump where they would condense and contaminate it. Particularly large cold traps are necessary when removing large amounts of liquid as in freeze drying. Cold traps also refer to the application of cooled surfaces or baffles to prevent oil vapours from flowing from a pump and into a chamber. In such a case, a baffle or a section of pipe containing a number of cooled vanes, will be attached to the inlet of an existing pumping system. By cooling the baffle, either with a cryogen such as a dry ice mixture, or by use of an electrically driven Peltier element, oil vapour molecules that strike the baffle vanes will condense and thus be removed from the pumped cavity. Applications Pumps that use oil either as their working fluid (diffusion pumps), or as thei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Architecture
Architecture is the art and technique of designing and building, as distinguished from the skills associated with construction. It is both the process and the product of sketching, conceiving, planning, designing, and constructing buildings or other structures. The term comes ; ; . Architectural works, in the material form of buildings, are often perceived as cultural symbols and as works of art. Historical civilizations are often identified with their surviving architectural achievements. The practice, which began in the prehistoric era, has been used as a way of expressing culture for civilizations on all seven continents. For this reason, architecture is considered to be a form of art. Texts on architecture have been written since ancient times. The earliest surviving text on architectural theories is the 1st century AD treatise '' De architectura'' by the Roman architect Vitruvius, according to whom a good building embodies , and (durability, utility, and beauty). ...

Reindeer
Reindeer (in North American English, known as caribou if wild and ''reindeer'' if domesticated) are deer in the genus ''Rangifer''. For the last few decades, reindeer were assigned to one species, ''Rangifer tarandus'', with about 10 subspecies. A 2022 revision of the genus elevated five of the subspecies to species (see Taxonomy below). They have a circumpolar distribution and are native to the Arctic, sub-Arctic, tundra, boreal forest, and mountainous regions of northern Europe, Siberia, and North America. Reindeer occur in both migratory and sedentary populations, and their herd sizes vary greatly in different regions. The tundra subspecies are adapted for extreme cold, and some are adapted for long-distance migration. Reindeer vary greatly in size and color from the smallest species, the Svalbard reindeer (''R. t. platyrhynchus''), to the largest subspecies, Osborn's caribou (''R. t. osborni''). Although reindeer are quite numerous, some species and subspecies are in d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ice Crystals
Ice crystals are solid ice exhibiting atomic ordering on various length scales and include hexagonal columns, hexagonal plates, dendritic crystals, and diamond dust. Formation The hugely symmetric shapes are due to depositional growth, namely, direct deposition of water vapor onto the ice crystal. Depending on environmental temperature and humidity, ice crystals can develop from the initial hexagonal prism into numerous symmetric shapes. Possible shapes for ice crystals are columns, needles, plates and dendrites. If the crystal migrates into regions with different environmental conditions, the growth pattern may change, and the final crystal may show mixed patterns. Ice crystals tend to fall with their major axis aligned along the horizontal, and are thus visible in polarimetric weather radar signatures with enhanced (positive) differential reflectivity values. Electrification of ice crystals can induce alignments different from the horizontal. Electrified ice crystals are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inca Empire
The Inca Empire (also known as the Incan Empire and the Inka Empire), called ''Tawantinsuyu'' by its subjects, (Quechua for the "Realm of the Four Parts", "four parts together" ) was the largest empire in pre-Columbian America. The administrative, political and military center of the empire was in the city of Cusco. The Inca civilization arose from the Peruvian highlands sometime in the early 13th century. The Spanish began the conquest of the Inca Empire in 1532 and by 1572, the last Inca state was fully conquered. From 1438 to 1533, the Incas incorporated a large portion of western South America, centered on the Andean Mountains, using conquest and peaceful assimilation, among other methods. At its largest, the empire joined modern-day Peru, what are now western Ecuador, western and south central Bolivia, northwest Argentina, the southwesternmost tip of Colombia and a large portion of modern-day Chile, and into a state comparable to the historical empires of Eurasia ...
