Accidents And Incidents Involving České Dráhy
An accident is an unintended, normally unwanted event that was not deliberately caused by humans. The term ''accident'' implies that the event may have been caused by unrecognized or unaddressed risks. Many researchers, insurers and attorneys who specialize in unintentional injury prefer to avoid using the term ''accident'', and focus on conditions that increase risk of severe injury or that reduce injury incidence and severity. For example, when a tree falls down during a wind storm, its fall may not have been directly caused by human error, but the tree's type, size, health, location, or improper maintenance may have contributed to the result. Most car crashes are the result of dangerous behavior and not purely ''accidents''; however, English speakers started using that word in the mid-20th century as a result of media manipulation by the US automobile industry. Accidental deaths were much less frequent before high-powered machinery began to spread with the Industrial Revolutio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green Bank 300ft Collapsed Telescope
Green is the color between cyan and yellow on the visible spectrum. It is evoked by light which has a dominant wavelength of roughly 495570 nm. In subtractive color systems, used in painting and color printing, it is created by a combination of yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content. During post-classical and early modern Europe, green was the color commonly associated with wealth, merchants, bankers, and the gentry, while re ...

Sports Injury
Sports injuries occur during participation in sports or exercise in general. Globally, around 40% of individuals engage in some form of regular exercise or organized sports, with upwards of 60% of US high school students participating in one or more sports. Sports injuries account for 15 - 20% of annual acute care visits with an incidence of 1.79 - 6.36 injuries per 1,000 hours of participation. Sports injuries can be broken down into the types of injuries, risk factors and prevention and the overall impact that injuries have on athletes. Types of sport injury The type of sports injury suffered varies greatly based on gender, age and sport. Nonetheless, those with the highest prevalence remain contusions, fractures and sprains, followed closely by wounds and overuse injuries. Also common, the possible severity of head and neck injuries are important to consider. It is also paramount to place emphasis on the specific injuries that are most commonly encountered by sports medicine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferries
A ferry is a boat or ship that transports passengers, and occasionally vehicles and cargo, across a body of water. A small passenger ferry with multiple stops, like those in Venice, Italy, is sometimes referred to as a water taxi or water bus. Ferries form a part of the public transport systems of many waterside cities and islands, allowing direct transit between points at a capital cost much lower than bridges or tunnels. Ship connections of much larger distances (such as over long distances in water bodies like the Baltic Sea) may also be called ferry services, and many carry vehicles. History The profession of the ferryman is embodied in Greek mythology in Charon, the boatman who transported souls across the River Styx to the Underworld. Speculation that a pair of oxen propelled a ship having a water wheel can be found in 4th century Roman literature "''Anonymus De Rebus Bellicis''". Though impractical, there is no reason why it could not work and such a ferry, modifie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
