Hockey Stick
A hockey stick is a piece of sports equipment used by the players in all the forms of hockey to move the ball or puck (as appropriate to the type of hockey) either to push, pull, hit, strike, flick, steer, launch or stop the ball/ puck during play with the objective being to move the ball/puck around the playing area using the stick, and then trying to score. The word "stick" is a very generic term for the equipment since the different disciplines of hockey require significant differences in both the form and the size of the stick used for it to be effective in the different sports. Field/ice/roller hockey all have a visually similar form of stick with a long shaft or handle which can be held with two hands, and a curved and flattened end; the end and curvature of these sticks are generally the most visible differences between the sticks for these sports. A modern underwater hockey stick bears little resemblance to any field/ice/roller hockey stick, since it is much smaller to ena ...

Paul Stastny
Paul Stastny (born December 27, 1985) is a Canadian-born American professional ice hockey center for the Carolina Hurricanes of the National Hockey League (NHL). He has previously played for the Colorado Avalanche, St. Louis Blues, Winnipeg Jets and Vegas Golden Knights of the National Hockey League (NHL). Of Slovak lineage, Stastny is the son of Peter Šťastný, a Hockey Hall of Famer who played for the Colorado Avalanche's predecessor, the Quebec Nordiques, and finished his career with the St. Louis Blues.

After winning the NCAA Men's Ice Hockey Championship in his first season playing for the Pioneers, he rem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southsea
Southsea is a seaside resort and a geographic area of Portsmouth, Portsea Island in England. Southsea is located 1.8 miles (2.8 km) to the south of Portsmouth's inner city-centre. Southsea is not a separate town as all of Portsea Island's settlements (including Southsea) were incorporated into the boundaries of Portsmouth in 1904. Southsea began as a fashionable 19th-century Victorian seaside resort named ''Croxton Town'', after a Mr Croxton who owned the land. As the resort grew, it adopted the name of nearby Southsea Castle, a seafront fort constructed in 1544 to help defend the Solent and approaches to Portsmouth Harbour. In 1879, South Parade Pier was opened by Princess Edward of Saxe-Weimar in Southsea. The pier began operating a passenger steamer service across the Solent to the Isle of Wight. This service gave rise to the idea of linking Southsea and its pier to Portsmouth's railway line, and for tourists to bypass the busy town of Portsmouth and its crowded harb ...

Octopush
Underwater hockey (UWH), (also known as Octopush in the United Kingdom) is a globally played limited-contact sport in which two teams compete to manoeuvre a puck across the bottom of a swimming pool into the opposing team's goal by propelling it with a hockey stick (or pusher). A key challenge of the game is that players are not able to use breathing devices such as scuba gear whilst playing, they must hold their breath. The game originated in England in 1954 when Alan Blake, a founder of the newly formed Southsea Sub-Aqua Club, invented the game he called Octopush as a means of keeping the club's members interested and active over the cold winter months when open-water diving lost its appeal. Underwater hockey is now played worldwide, with the Confédération Mondiale des Activités Subaquatiques, abbreviated CMAS, as the world governing body. The first Underwater Hockey World Championship was held in Canada in 1980 after a false start in 1979 brought about by internationa ...

Ambidexterity
Ambidexterity is the ability to use both the right and left hand equally well. When referring to objects, the term indicates that the object is equally suitable for right-handed and left-handed people. When referring to humans, it indicates that a person has no marked preference for the use of the right or left hand. Only about one percent of people are naturally ambidextrous, which equates to about 70,000,000 people in the world. In modern times, it is common to find some people considered ambidextrous who were originally left-handed and who learned to be ambidextrous, either deliberately or as a result of training in schools or in jobs where right-handed habits are often emphasized or required. Since many everyday devices (such as can openers and scissors) are asymmetrical and designed for right-handed people, many left-handers learn to use them right-handedly due to the rarity or lack of left-handed models. Thus, left-handed people are more likely to develop motor skills in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Handedness
In human biology, handedness is an individual's preferential use of one hand, known as the dominant hand, due to it being stronger, faster or more Fine motor skill, dextrous. The other hand, comparatively often the weaker, less dextrous or simply less subjectively preferred, is called the non-dominant hand. In a study from 1975 on 7688 children in US grades 1-6, Left handers comprised 9.6% of the sample, with 10.5% of male children and 8.7% of female children being left-handed. Handedness is often defined by one's writing hand, as it is fairly common for people to prefer to do some tasks with each hand. There are examples of true ambidexterity (equal preference of either hand), but it is rare—most people prefer using one hand for most purposes. Most of the current research suggests that left-handedness has an epigenetic marker—a combination of genetics, biology and the environment. Because the vast majority of the population is right-handed, many devices are designed for u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PTFE
Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. It is one of the best-known and widely applied PFAS. The commonly known brand name of PTFE-based composition is Teflon by Chemours, a spin-off from DuPont, which originally discovered the compound in 1938. Polytetrafluoroethylene is a fluorocarbon solid, as it is a high-molecular-weight polymer consisting wholly of carbon and fluorine. PTFE is hydrophobic: neither water nor water-containing substances wet PTFE, as fluorocarbons exhibit only small London dispersion forces due to the low electric polarizability of fluorine. PTFE has one of the lowest coefficients of friction of any solid. Polytetrafluoroethylene is used as a non-stick coating for pans and other cookware. It is non-reactive, partly because of the strength of carbon–fluorine bonds, so it is often used in containers and pipework for reactive and corrosive chemicals. Where used as a lubricant, PTFE ...

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 research pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Homogeneous
Homogeneity and heterogeneity are concepts often used in the sciences and statistics relating to the uniformity of a substance or organism. A material or image that is homogeneous is uniform in composition or character (i.e. color, shape, size, weight, height, distribution, texture, language, income, disease, temperature, radioactivity, architectural design, etc.); one that is heterogeneous is distinctly nonuniform in at least one of these qualities. Heterogeneous Mixtures, in chemistry, is where certain elements are unwillingly combined and, when given the option, will separate. Etymology and spelling The words ''homogeneous'' and ''heterogeneous'' come from Medieval Latin ''homogeneus'' and ''heterogeneus'', from Ancient Greek ὁμογενής (''homogenēs'') and ἑτερογενής (''heterogenēs''), from ὁμός (''homos'', “same”) and ἕτερος (''heteros'', “other, another, different”) respectively, followed by γένος (''genos'', “kind”); - ...
