Qamutiik
A qamutiik ( iu, ᖃᒧᑏᒃ; alternate spellings ''qamutik'' (single sledge runner), ''komatik'', kl, qamutit) is a sled designed to travel on snow and ice, built using traditional Inuit design techniques. Adapted to the Arctic sea ice environment, such sleds are still widely used in the 21st century for travel in Arctic regions. Design The key feature of the qamutiik is that it is not built with nails or pins to hold the runners and cross pieces in place. Each piece is drilled and lashed to the next, providing a flexibility of movement that can endure the pounding of travel on open sea ice, frozen land, ice floes, and across the heavy ice of tidal zones. The cross pieces are called ''napooks''. Each napook is notched near the ends to take a lashing which is passed through holes drilled through the runners. The first and last napooks are lashed individually to the runners, using a more secure knot using two holes in the runners. For the central napooks, there is a single ho ...

Nylon
Nylon is a generic designation for a family of synthetic polymers composed of polyamides ( repeating units linked by amide links).The polyamides may be aliphatic or semi-aromatic. Nylon is a silk-like thermoplastic, generally made from petroleum, that can be melt-processed into fibers, films, or shapes. Nylon polymers can be mixed with a wide variety of additives to achieve many property variations. Nylon polymers have found significant commercial applications in fabric and fibers (apparel, flooring and rubber reinforcement), in shapes (molded parts for cars, electrical equipment, etc.), and in films (mostly for food packaging). History DuPont and the invention of nylon Researchers at DuPont began developing cellulose based fibers, culminating in the synthetic fiber rayon. DuPont's experience with rayon was an important precursor to its development and marketing of nylon. DuPont's invention of nylon spanned an eleven-year period, ranging from the initial resear ...

Sledding
Sledding, sledging or sleighing is a winter sport typically carried out in a prone or seated position on a vehicle generically known as a sled (North American), a sledge (British), or a sleigh. It is the basis of three Olympic sports: luge, skeleton and bobsledding. When practised on sand, it is known as a form of sandboarding. In Russia sledges are used for maritime activities including fishing and commuting from island to island on ice. History The practical use of sleds is ancient and widespread. They were developed in areas with consistent winter snow cover, as vehicles to transport materials and/or people, far more efficiently than wheeled vehicles could in icy and snowy conditions. Early designs included hand-pulled sizes as well as larger dog, horse, or ox drawn versions. Early examples of sleds and sledges were found in the Oseberg Viking ship excavation. The Toboggan sled is also a traditional form of transport used by the Innu and Cree of northern Canada and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snowmobile
A snowmobile, also known as a Ski-Doo, snowmachine, sled, motor sled, motor sledge, skimobile, or snow scooter, is a motorized vehicle designed for winter travel and recreation on snow. It is designed to be operated on snow and ice and does not require a road or trail, but most are driven on open terrain or trails. Snowmobiling is a sport that many people have taken on as a serious hobby. Older snowmobiles could generally accommodate two people; however, most snowmobiles manufactured since the 1990s have been designed to only accommodate one person. Snowmobiles built with the ability to accommodate two people are referred to as "2-up" snowmobiles or "touring" models and make up an extremely small share of the market. Most snowmobiles do not have any enclosures, except for a windshield, and their engines normally drive a continuous track at the rear. Skis at the front provide directional control. Early snowmobiles used simple rubber tracks, but modern snowmobiles' tracks are us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sled Dog
A sled dog is a dog trained and used to pull a land vehicle in harness, most commonly a sled over snow. Sled dogs have been used in the Arctic for at least 8,000 years and, along with watercraft, were the only transportation in Arctic areas until the introduction of semi-trailer trucks, snowmobiles and airplanes in the 20th century, hauling supplies in areas that were inaccessible by other methods. They were used with varying success in the explorations of both poles, as well as during the Alaskan gold rush. Sled dog teams delivered mail to rural communities in Alaska, Yukon, Northwest Territories and Nunavut. Sled dogs today are still used by some rural communities, especially in areas of Russia, Canada, and Alaska as well as much of Greenland. They are used for recreational purposes and racing events, such as the Iditarod Trail and the Yukon Quest. History Sled dogs are used in countries such as Canada, Greenland, Siberia, Chukotka, Norway, Sweden, and Alaska. Sled ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Day Trip
A day trip is a visit to a tourist destination or visitor attraction from a person's home, hotel, or hostel in the morning, returning to the same lodging in the evening. The day trip is a form of recreational travel and leisure to a location that is close enough to make a round-trip within a day but does not require an overnight stay. The logistics and/or costs of spending nights on the road are worth avoiding. Such travel of using one location as a homebase is popular with budget and active travelers to avoid finding new lodging at each destination. A caregiver may take a day trip from their home to return to their children or pets. History In medieval times a destination for such a trip would be religious (to a nearby shrine) or commercial (for example, to a seasonal fair). Later, in England, visits to stately homes by those who regarded themselves middle class became frequent, and it was the tradition to reward the butler or housekeeper with a tip (gratuity) for providing ...

Canvas
Canvas is an extremely durable plain-woven fabric used for making sails, tents, marquees, backpacks, shelters, as a support for oil painting and for other items for which sturdiness is required, as well as in such fashion objects as handbags, electronic device cases, and shoes. It is popularly used by artists as a painting surface, typically stretched across a wooden frame. Modern canvas is usually made of cotton or linen, or sometimes polyvinyl chloride (PVC), although historically it was made from hemp. It differs from other heavy cotton fabrics, such as denim, in being plain weave rather than twill weave. Canvas comes in two basic types: plain and duck. The threads in duck canvas are more tightly woven. The term ''duck'' comes from the Dutch word for cloth, ''doek''. In the United States, canvas is classified in two ways: by weight (ounces per square yard) and by a graded number system. The numbers run in reverse of the weight so a number 10 canvas is lighter than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windbreak
A windbreak (shelterbelt) is a planting usually made up of one or more rows of trees or shrubs planted in such a manner as to provide shelter from the wind and to protect soil from erosion. They are commonly planted in hedgerows around the edges of fields on farms. If designed properly, windbreaks around a home can reduce the cost of heating and cooling and save energy. Windbreaks are also planted to help keep snow from drifting onto roadways or yards. Farmers sometimes use windbreaks to keep snow drifts on farm land that will provide water when the snow melts in the spring. Other benefits include contributing to a microclimate around crops (with slightly less drying and chilling at night), providing habitat for wildlife, and, in some regions, providing wood if the trees are harvested. Windbreaks and intercropping can be combined in a farming practice referred to as alleycropping, or being deployed along riparian buffer stripes. Fields are planted in rows of different crops surr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hunting
Hunting is the human practice of seeking, pursuing, capturing, or killing wildlife or feral animals. The most common reasons for humans to hunt are to harvest food (i.e. meat) and useful animal products ( fur/ hide, bone/tusks, horn/antler, etc.), for recreation/taxidermy (see trophy hunting), to remove predators dangerous to humans or domestic animals (e.g. wolf hunting), to eliminate pests and nuisance animals that damage crops/livestock/poultry or spread diseases (see varminting), for trade/tourism (see safari), or for ecological conservation against overpopulation and invasive species. Recreationally hunted species are generally referred to as the ''game'', and are usually mammals and birds. A person participating in a hunt is a hunter or (less commonly) huntsman; a natural area used for hunting is called a game reserve; an experienced hunter who helps organize a hunt and/or manage the game reserve is known as a gamekeeper. Many non-human animals also hunt (see p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inuit Hunters' Camp 1995-06-11
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 who are n ...

Polyurethane
Polyurethane (; often abbreviated PUR and PU) refers to a class of polymers composed of organic units joined by carbamate (urethane) links. In contrast to other common polymers such as polyethylene and polystyrene, polyurethane is produced from a wide range of starting materials. This chemical variety produces polyurethanes with different chemical structures leading to many different applications. These include rigid and flexible foams, varnishes and coatings, adhesives, electrical potting compounds, and fibers such as spandex and PUL. Foams are the largest application accounting for 67% of all polyurethane produced in 2016. A polyurethane is typically produced by reacting an isocyanate with a polyol. Since a polyurethane contains two types of monomers, which polymerize one after the other, they are classed as alternating copolymers. Both the isocyanates and polyols used to make a polyurethane contain two or more functional groups per molecule. Global production in 2019 wa ...
