Polyethylene
Polyethylene or polythene (abbreviated PE; IUPAC name polyethene or poly(methylene)) is the most commonly produced plastic. It is a polymer, primarily used for packaging ( plastic bags, plastic films, geomembranes and containers including bottles, etc.). , over 100 million tonnes of polyethylene resins are being produced annually, accounting for 34% of the total plastics market. Many kinds of polyethylene are known, with most having the chemical formula (C2H4)''n''. PE is usually a mixture of similar polymers of ethylene, with various values of ''n''. It can be ''low-density'' or ''high-density'': low-density polyethylene is extruded using high pressure () and high temperature (), while high-density polyethylene is extruded using low pressure () and low temperature (). Polyethylene is usually thermoplastic, but it can be modified to become thermosetting instead, for example, in cross-linked polyethylene. History Polyethylene was first synthesized by the German chemist Hans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wānaka
Wānaka () is a popular ski and summer resort town in the Otago region of the South Island of New Zealand. At the southern end of Lake Wānaka, it is at the start of the Clutha River/Mata-Au and is the gateway to Mount Aspiring National Park. Wānaka is primarily a resort town with both summer and winter seasons. Its economy is based on the many outdoor opportunities this offers. Historically, Māori visited the Wānaka area to hunt and fish in summer, or on their way to seek ''pounamu'' (greenstone) on the West Coast. Ngāi Tahu abandoned their seasonal camps after a raid by a North Island war party in 1836. The current town was founded as Pembroke during the gold rush of the 19th century, and renamed to Wanaka in 1940. Along with the rest of the Queenstown-Lakes District, Wānaka is growing rapidly, with the population increasing by 50% between 2005 and 2015. Names ''Wānaka'' is the South Island dialect pronunciation of , which means 'sacred knowledge or a place of learn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lynn Lake, Manitoba
Lynn Lake is a town in the northwest region of Manitoba, Canada, approximately from Winnipeg. The town is the fourth-largest town in Manitoba in terms of land area. It is centred on the original urban community of Lynn Lake. The town was named after Lynn Smith, chief engineer of Sherritt Gordon Mines Ltd. There are many outfitters in the Lynn Lake area, offering services for most wilderness experiences, including sport fishing and bear and moose hunting. History Lynn Lake was founded in 1950, when a deposit of nickel ore was discovered. The nickel mine was developed, and soon after, gold was also discovered. Most of Lynn Lake's 208 houses and commercial buildings were moved from the town of Sherridon, 120 miles south, over cat train trails. The buildings were moved by digging out the foundations and loading them onto tricycle winter-freighting sleighs pulled by Linn tractors and caterpillar crawlers. The buildings were loaded onto the last sleigh on each cat train, which were u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Esrange
Esrange Space Center (short form Esrange) is a rocket range and research centre located about 40 kilometers east of the town of Kiruna in northern Sweden. It is a base for scientific research with high-altitude balloons, investigation of the aurora borealis, sounding rocket launches, and satellite tracking, among other things. Located 200 km north of the Arctic Circle and surrounded by a vast wilderness, its geographic location is ideal for many of these purposes. Esrange was built in 1964 by ESRO, the ''European Space Research Organisation'', which later became European Space Agency by merging with ELDO, the European Launcher Development Organisation. The first rocket launch from Esrange occurred on 19 November 1966. In 1972, ownership was transferred to the newly started Swedish Space Corporation. History In the 1960s Esrange was established as an ESRO sounding rocket launching range located in Kiruna (Sweden). This location was chosen because it was generally agreed tha ...

Superpressure Balloon
A superpressure balloon (SPB) is a style of aerostatic balloon where the volume of the balloon is kept relatively constant in the face of changes in ambient pressure outside the balloon, and the temperature of the contained lifting gas. This allows the balloon to keep a stable altitude for long periods. This is in contrast with much more common variable-volume balloons, which are either only partially filled with lifting gas, or made with more elastic materials. Also referred to as pumpkin or Ultra Long Distance Balloons (ULDB) balloons, the sealed balloon envelopes have a pumpkin shape at flight altitude. Operation In a variable-volume balloon, the volume of the lifting gas changes due to heating and cooling in the diurnal cycle. The cycle is magnified by a greenhouse effect inside the balloon, while the surrounding atmospheric gas is subject to a much more limited cyclical temperature change. As the lift gas heats and expands, the displacement of atmospheric gas increases, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
