Winterize
Winterization is the process of preparing something for winter. Humanitarian aid In emergency or disaster response situations, such as managed by the UNHCR, winterization activities include the distribution of items including blankets, quilts, kerosene, heating stoves, jerry cans, as well as thermal floor mats and insulation to make tents warmer and more resistant to harsh winter conditions. Summer home Some summer homes, also known as cabins or cottages, were built for summer use only and need to be winterized each Autumn. This entails locking them up, turning off water, electricity, and phone lines, and protecting various features from heavy snowfall. In the New England area, many wealthy families living in cities during the 19th century had summer homes in the mountains. This was to flee the onset of yellow fever and other epidemics which often struck in the summer months, when city plumbing problems and stagnant horse manure in the streets caused a health hazard. Winteri ...

Camping
Camping is an outdoor activity involving overnight stays away from home, either without shelter or using basic shelter such as a tent, or a recreational vehicle. Typically, participants leave developed areas to spend time outdoors in more natural ones in pursuit of activities providing them enjoyment or an educational experience. The night (or more) spent outdoors distinguishes camping from day-tripping, picnicking, and other similarly short-term recreational activities. Camping as a recreational activity became popular among elites in the early 20th century. With time, it grew in popularity among other socioeconomic classes. Modern campers frequent publicly owned natural resources such as national and state parks, wilderness areas, and commercial campgrounds. In a few countries, such as Sweden and Scotland, public camping is legal on privately held land as well. Camping is a key part of many youth organizations around the world, such as Scouting, which use it to teach bot ...

Ontario Science Centre
The Ontario Science Centre, formally the Centennial Museum of Science and Technology, is a science museum in Toronto, Ontario, Canada. It is located near the Don Valley Parkway about northeast of downtown on Don Mills Road just south of Eglinton Avenue East in the former city of North York. It is built down the side of a wooded ravine formed by one branch of the Don River located in Flemingdon Park. History Planning for the Science Centre started in 1961 during Toronto's massive expansion of the late 1950s and 1960s. In 1964, Toronto architect Raymond Moriyama was hired to design the site. Construction started in 1966 with plans to open the "Centennial Centre of Science and Technology" as part of the Canadian Centennial celebrations in 1967. However construction was not completed in 1967, and the Science Centre did not open to the public until two years later, on September 26, 1969. The buildings and design were part of a broader change in Canadian architecture, and remain an ...

Block Heater
A block heater is used in cold climates to warm an engine prior to starting. They are mostly used for car engines; however they have also been used in aircraft engines. The most common design of block heater is an electrical heating element embedded in the engine block. Purpose Pre-heating of an engine is primarily used to make it easier to start. Added benefits are: *The cabin heater produces heat sooner for comfort and to de-fog the windscreen. *Reduction of condensation of fuel on cold cylinder walls during start thus ** saving fuel and reducing exhaust emissions and ** reducing oil dilution by gasoline scraped into the oil pan by the piston rings. *The engine reaches operating temperature sooner, so the engine does not run rich as long. This further reduces fuel consumption and emissions. *Less load on the starter and battery thereby prolonging their service lives. *Less engine wear as oil circulation is improved. *Reduces the need for a Remote starter, thereby further ...

Internal Combustion Engine
An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons ( piston engine), turbine blades (gas turbine), a rotor (Wankel engine), or a nozzle ( jet engine). This force moves the component over a distance, transforming chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to. This replaced the external combustion engine for applications where the weight or size of an engine was more important. The first commercially successful internal combustion engine was created by Étienne Lenoir around 1860, and the first modern internal combustion engine, known ...

Polar Region
The polar regions, also called the frigid geographical zone, zones or polar zones, of Earth are the regions of the planet that surround its geographical poles (the North Pole, North and South Poles), lying within the polar circles. These high latitudes are dominated by floating Arctic ice pack, sea ice covering much of the Arctic Ocean in the north, and by the Antarctic ice sheet on the continent of Antarctica and the Southern Ocean in the south. Definitions The Arctic has various definitions, including the region north of the Arctic Circle (currently Epoch 2010 at 66°33'44" N), or just the region north of 60th parallel north, 60° north latitude, or the region from the North Pole north to the Tree line, timberline. The Antarctic is usually defined simply as south of 60th parallel south, 60° south latitude, or the continent of Antarctica. The 1959 Antarctic Treaty System, Antarctic Treaty uses the former definition. The two polar regions are distinguished from the other two c ...

Thermal Insulation
Thermal insulation is the reduction of heat transfer (i.e., the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence. Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials. Heat flow is an inevitable consequence of contact between objects of different temperature. Thermal insulation provides a region of insulation in which thermal conduction is reduced, creating a thermal break or thermal barrier, or thermal radiation is reflected rather than absorbed by the lower-temperature body. The insulating capability of a material is measured as the inverse of thermal conductivity (k). Low thermal conductivity is equivalent to high insulating capability ( resistance value). In thermal engineering, other important properties of insulating materials are product density (ρ) and specific heat capacity (c). Definition T ...

Heating
A central heating system provides warmth to a number of spaces within a building from one main source of heat. It is a component of heating, ventilation, and air conditioning (short: HVAC) systems, which can both cool and warm interior spaces. A central heating system has a furnace that converts fuel or electricity to heat. The heat is circulated through the building either by fans forcing heated air through ducts, circulation of low-pressure steam to radiators in each heated room, or pumps that circulate hot water through room radiators. Primary energy sources may be fuels like coal or wood, oil, kerosene, natural gas, or electricity. Compared with systems such as fireplaces and wood stoves, a central heating plant offers improved uniformity of temperature control over a building, usually including automatic control of the furnace. Large homes or buildings may be divided into individually controllable zones with their own temperature controls. Automatic fuel (and sometimes ash ...

Skiing
Skiing is the use of skis to glide on snow. Variations of purpose include basic transport, a recreational activity, or a competitive winter sport. Many types of competitive skiing events are recognized by the International Olympic Committee (IOC), and the International Ski Federation (FIS). History Skiing has a history of almost five millennia. Although modern skiing has evolved from beginnings in Scandinavia, it may have been practiced more than 100 centuries ago in what is now China, according to an interpretation of ancient paintings. However, this continues to be debated. The word "ski" comes from the Old Norse word "skíð" which means to "split piece of wood or firewood". Asymmetrical skis were used in northern Finland and Sweden until at least the late 19th century. On one foot, the skier wore a long straight non-arching ski for sliding, and a shorter ski was worn on the other foot for kicking. The underside of the short ski was either plain or covered with animal ...

UNHCR
The United Nations High Commissioner for Refugees (UNHCR) is a United Nations agency mandated to aid and protect refugees, forcibly displaced communities, and stateless people, and to assist in their voluntary repatriation, local integration or resettlement to a third country. It is headquartered in Geneva, Switzerland, with over 17,300 staff working in 135 countries. Background UNHCR was created in 1950 to address the refugee crisis that resulted from World War II. The 1951 Refugee Convention established the scope and legal framework of the agency's work, which initially focused on Europeans uprooted by the war. Beginning in the late 1950s, displacement caused by other conflicts, from the Hungarian Uprising to the decolonization of Africa and Asia, broadened the scope of UNHCR's operations. Commensurate with the 1967 Protocol to the Refugee Convention, which expanded the geographic and temporal scope of refugee assistance, UNHCR operated across the world, with the bu ...

Squam Lake
Squam Lake is a lake located in the Lakes Region of central New Hampshire, United States, south of the White Mountains, straddling the borders of Grafton, Carroll, and Belknap counties. The largest town center on the lake is Holderness. The lake is located northwest of much larger Lake Winnipesaukee. It drains via a short natural channel into Little Squam Lake, and then through a dam at the head of the short Squam River into the Pemigewasset at Ashland. Covering , Squam is the second-largest lake located entirely in New Hampshire. Squam Lake was originally called ''Keeseenunknipee'', which meant "the goose lake in the highlands". The white settlers that followed shortened the name to "Casumpa", "Kusumpy" and/or "Kesumpe" around 1779. In the early 19th century, the lake was given another Abenaki name, ''Asquam'', which means "water". Finally, in the early 20th century, Asquam was shortened to its present version, Squam. Squam Lake is much less commercialized than its nei ...
