Artificial Ski Slopes
A dry ski slope or artificial ski slope is a ski slope that mimics the attributes of snow using materials that are stable at room temperature, to enable people to ski, snowboard or snow tube in places where natural, snow-covered slopes are inconvenient or unavailable. Although commonly known as "dry ski slopes", many slopes are lubricated using a mist or jet system to increase speed and prevent damage to equipment from friction heat build-up. Materials Early materials A variety of materials can be found on dry ski slopes. Early efforts to mimic snow involved laying extruded plastic tiles with upward spikes in an attempt to provide grip. These were unpopular as they provided little grip and turning capability and the experience was similar to skiing across ice. However, in present day, many ski slopes (both indoor and outdoor) continue to use plastic, injection moulded tiles. Quality has improved and many dry ski slopes in the Netherlands use these tiles for training and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lubrication
Lubrication is the process or technique of using a lubricant to reduce friction and wear and tear in a contact between two surfaces. The study of lubrication is a discipline in the field of tribology. Lubrication mechanisms such as fluid-lubricated systems are designed so that the applied load is partially or completely carried by hydrodynamic or hydrostatic pressure, which reduces solid body interactions (and consequently friction and wear). Depending on the degree of surface separation, different lubrication regimes can be distinguished. Adequate lubrication allows smooth, continuous operation of machine elements, reduces the rate of wear, and prevents excessive stresses or seizures at bearings. By repelling water and other substances, it also reduces corrosion. When lubrication breaks down, components can rub destructively against each other, causing heat, local welding, destructive damage and failure. Lubrication mechanisms Fluid-lubricated systems As the load incre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kendal, once Kirkby in Kendal or Kirkby Kendal, is a market town and civil parish in the unitary authority of Westmorland and Furness, England. It lies within the River Kent's dale, from which its name is derived, just outside the boundary of the Lake District National Park.

Huddersfield
Huddersfield is a town in the Metropolitan Borough of Kirklees in West Yorkshire, England. It is the administrative centre and largest settlement in the Kirklees district. The town is in the foothills of the Pennines. The River Holme's confluence into the similar-sized Colne is to the south of the town centre which then flows into the Calder in the north eastern outskirts of the town. The rivers around the town provided soft water required for textile treatment in large weaving sheds; this made it a prominent mill town with an economic boom in the early part of the Victorian era Industrial Revolution. The town centre has much neoclassical Victorian architecture. An example is , which is a Grade I listed building described by John Betjeman as "the most splendid station façade in England". It won the Europa Nostra award for architecture. Huddersfield hosts the University of Huddersfield and three colleges: Greenhead College, Kirklees College and Huddersfield New Coll ...

Silicone
In Organosilicon chemistry, organosilicon and polymer chemistry, a silicone or polysiloxane is a polymer composed of repeating units of siloxane (, where R = Organyl group, organic group). They are typically colorless oils or elastomer, rubber-like substances. Silicones are used in sealants, adhesives, lubricants, medicine, cooking utensils, thermal insulation, and electrical insulation. Some common forms include silicone oil, silicone grease, grease, silicone rubber, rubber, silicone resin, resin, and Caulking, caulk. Silicone is often confused with one of its constituent elements, silicon, but they are distinct substances. Silicon is a chemical element, a hard dark-grey semiconductor, semiconducting metalloid, which in its crystalline form is used to make integrated circuits ("electronic chips") and solar cells. Silicones are compounds that contain silicon, carbon, hydrogen, oxygen, and perhaps other kinds of atoms as well, and have many very different physical and chemical ...
