Toboggans
A toboggan is a simple sled used in snowy winter recreation. It is also a traditional form of cargo transport used by the Innu, Cree and Ojibwe of North America, sometimes part of a dog train. It is used on snow to carry one or more people (often children) down a hill or other slope for recreation, or as a rescue sled. Designs vary from simple, traditional models to modern engineered composites. A toboggan differs from most sleds or sleighs in that it has no runners or skis (or only low ones) on the underside. The bottom of a toboggan rides directly on the snow. Some parks include designated toboggan hills where ordinary sleds are not allowed and which may include toboggan runs similar to bobsleigh courses. Toboggans can vary depending on the climate and geographical region. Such examples are Tangalooma (Australia) where toboggans are made from Masonite boards and used for travelling down steep sand dunes at speeds up to .

Rescue Toboggan
A rescue toboggan, also known as a rescue sled or emergency rescue sledge, or by the Finnish word ahkio (also transliteration, transliterated akia, ackja, akija, and akja), is a carrier for transporting a person or goods on snowy or icy surfaces. It is used by mountain rescue or ski patrol teams to evacuate an injured skier or snowboarder. There are related designs for use on water to carry accident victims or emergency equipment. A rescue toboggan takes the form of a ''pulk'' or small sled shaped as an elongated boat-like pan, usually made of aluminum or fiberglass, with vaulted ends, each of which may be attached to forked extending handles. There are many variations and adaptations such as a brake, stability fins, and an integrated or removable Litter (rescue basket), litter. A particular variation may be preferred by various regions or individual ski patrollers.

Sled
A sled, skid, sledge, or sleigh is a land vehicle that slides across a surface, usually of ice or snow. It is built with either a smooth underside or a separate body supported by two or more smooth, relatively narrow, longitudinal runners similar in principle to skis. This reduces the amount of friction, which helps to carry heavy loads. Some designs are used to transport passengers or cargo across relatively level ground. Others are designed to go downhill for recreation, particularly by children, or competition (compare cross-country skiing with its downhill cousin). Shades of meaning differentiating the three terms often reflect regional variations depending on historical uses and prevailing climate. In British English, ''sledge'' is the general term, and more common than ''sled''. '' Toboggan'' is sometimes used synonymously with ''sledge'' but more often to refer to a particular type of sledge without runners. ''Sleigh'' refers to a moderate to large-sized, usuall ...

Industrial Revolution
The Industrial Revolution, sometimes divided into the First Industrial Revolution and Second Industrial Revolution, was a transitional period of the global economy toward more widespread, efficient and stable manufacturing processes, succeeding the Second Agricultural Revolution. Beginning in Kingdom of Great Britain, Great Britain around 1760, the Industrial Revolution had spread to continental Europe and the United States by about 1840. This transition included going from craft production, hand production methods to machines; new Chemical industry, chemical manufacturing and Puddling (metallurgy), iron production processes; the increasing use of Hydropower, water power and Steam engine, steam power; the development of machine tools; and rise of the mechanisation, mechanised factory system. Output greatly increased, and the result was an unprecedented rise in population and population growth. The textile industry was the first to use modern production methods, and textiles b ...

Great Lakes
The Great Lakes, also called the Great Lakes of North America, are a series of large interconnected freshwater lakes spanning the Canada–United States border. The five lakes are Lake Superior, Superior, Lake Michigan, Michigan, Lake Huron, Huron, Lake Erie, Erie, and Lake Ontario, Ontario (though hydrologically, Lake Michigan–Huron, Michigan and Huron are a single body of water, joined at the Straits of Mackinac). The Great Lakes Waterway enables modern travel and shipping by water among the lakes. The lakes connect to the Atlantic Ocean via the Saint Lawrence River, and to the Mississippi River basin through the Illinois Waterway. The Great Lakes are the largest group of freshwater lakes on Earth by total area and the second-largest by total volume. They contain 21% of the world's surface fresh water by volume. The total surface is , and the total volume (measured at the low water datum) is , slightly less than the volume of Lake Baikal (, 22–23% of the world's surface f ...

Loanword
A loanword (also a loan word, loan-word) is a word at least partly assimilated from one language (the donor language) into another language (the recipient or target language), through the process of borrowing. Borrowing is a metaphorical term that is well established in the linguistic field despite its acknowledged descriptive flaws: nothing is taken away from the donor language and there is no expectation of returning anything (i.e., the loanword). Loanwords may be contrasted with calques, in which a word is borrowed into the recipient language by being directly translated from the donor language rather than being adopted in (an approximation of) its original form. They must also be distinguished from cognates, which are words in two or more related languages that are similar because they share an etymological origin in the ancestral language, rather than because one borrowed the word from the other. Examples and related terms A loanword is distinguished from a calque (or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snowshoe
Snowshoes are specialized outdoor gear for walking over snow. Their large footprint spreads the user's weight out and allows them to travel largely on top of rather than through snow. Adjustable bindings attach them to appropriate winter footwear. Traditional snowshoes have a hardwood frame filled in with rawhide (material), rawhide latticework. Modern snowshoes are made of lightweight metal, plastic, and other synthetic materials. In the past, snowshoes were essential equipment for anyone dependent on travel in deep and frequent snowfall, such as Animal trapping, fur trappers. They retain that role in areas where motorized vehicles cannot reach or are inconvenient to use. However, their greatest contemporary use is for recreation. Snowshoeing is easy to learn and in appropriate conditions is a relatively safe and inexpensive recreational activity. However, doing so in icy, steep terrain requires both advanced skill and mountaineering-style pivoting-crampon snowshoes. Devel ...

Bobsled
Bobsleigh or bobsled is a winter sport in which teams of 2 to 4 athletes make timed speed runs down narrow, twisting, banked, iced tracks in a gravity-powered sleigh. International bobsleigh competitions are governed by the International Bobsleigh and Skeleton Federation (formerly the FIBT). The first bobsleds were built in the late 19th century in St. Moritz, Switzerland, by wealthy tourists from Victorian Britain who were staying at the Palace Hotel owned by Caspar Badrutt. The early sleds were adapted from boys' delivery sleds and toboggans. These eventually evolved into bobsleighs, luges and skeletons. Initially the tourists would race their hand-built contraptions down the narrow streets of St. Moritz; however, as collisions increased, growing opposition from St. Moritz residents led to bobsledding being eventually banned from public highways. In the winter of 1884, Badrutt had a purpose-built run constructed near the hamlet of Cresta. The Cresta Run remains the o ...

Whalebone
Baleen is a filter-feeding system inside the mouths of baleen whales. To use baleen, the whale first opens its mouth underwater to take in water. The whale then pushes the water out, and animals such as krill are filtered by the baleen and remain as a food source for the whale. Baleen is similar to bristles and consists of keratin, the same substance found in human fingernails, skin and hair. Baleen is a skin derivative. Some whales, such as the bowhead whale, have baleen of differing lengths. Other whales, such as the gray whale, only use one side of their baleen. These baleen bristles are arranged in plates across the upper jaw of whales. Depending on the species, a baleen plate can be long, and weigh up to . Its hairy fringes are called baleen hair or whalebone hair. They are also called baleen bristles, which in sei whales are highly calcified, with calcification functioning to increase their stiffness. Baleen plates are broader at the gumline (base). The plates have be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
