Henninger Turm-2005-Finale-Runde2-Spitzengruppe
Henninger is a family name that originated in Germany. The name is attested as 'Honigar' from the 13th century in Bavaria, and was borne by members of the nobility of the Holy Roman Empire and by the family that founded the Henninger Brewery. It is most prevalent today in Baden-Württemberg. History There are more than one, seemingly unrelated, Henninger branches from Germany. Seemingly there were branches formed from a variety of spellings in the regions of Hessia, Baden, and Saxony/Bavaria/Bohemia. The earliest origins of the Bavarian/Bohemian name date back to the Dark Ages and started with a different name altogether. In 978, the Saxon nobleman Bruno, Graf von Arneburg, died. His grandson, Wilhelm, Graf von Lutisburg seemingly took on the additional estate of 'von Seeberg' in 1089 due to marriage.

Titanium
Titanium is a chemical element with the symbol Ti and atomic number 22. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength, resistant to corrosion in sea water, aqua regia, and chlorine. Titanium was discovered in Cornwall, Great Britain, by William Gregor in 1791 and was named by Martin Heinrich Klaproth after the Titans of Greek mythology. The element occurs within a number of minerals, principally rutile and ilmenite, which are widely distributed in the Earth's crust and lithosphere; it is found in almost all living things, as well as bodies of water, rocks, and soils. The metal is extracted from its principal mineral ores by the Kroll and Hunter processes. The most common compound, titanium dioxide, is a popular photocatalyst and is used in the manufacture of white pigments. Other compounds include titanium tetrachloride (TiCl4), a component of smoke screens and catalysts; and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclist Removing Helmet After Cycling On Roads
Cycling, also, when on a two-wheeled bicycle, called bicycling or biking, is the use of Bicycle, cycles for transport, recreation, Physical exercise, exercise or sport. People engaged in cycling are referred to as "cyclists", "bicyclists", or "bikers". Apart from two-wheeled bicycles, "cycling" also includes the riding of unicycles, tricycles, quadricycles, recumbent bicycle, recumbent and similar human-powered transport, human-powered vehicles (HPVs). Bicycles were introduced in the 19th century and now number approximately one billion worldwide. They are the principal means of transportation in many parts of the world, especially in densely populated European cities. Cycling is widely regarded as an effective and efficient mode of transportation optimal for short to moderate distances. Bicycles provide numerous possible benefits in comparison with motor vehicles, including the sustained physical exercise involved in cycling, easier parking, increased maneuverability, and ...

Bicycle Helmets In New Zealand
Bicycle helmets have been mandatory in New Zealand since January 1994. The statute, delineated in Part 11 of the Land Transport (Road User) Rule 2004 (SR 2004/427), states that "A person must not ride, or be carried on, a bicycle on a road unless the person is wearing a safety helmet of an approved standard that is securely fastened." The law describes six different acceptable helmet standards.19 years) cyclists. Taylor and Scuffham cautioned that "the social costs saved due to fewer head injuries are likely to understate the true costs... our estimates of the net benefit from helmet wearing are likely to be understated". Research from Massey University in 2006 found that compulsory bicycle helmet laws led to a lower uptake of cycling, principally for aesthetic reasons. A 2010 study found a declining trend in the rate of traumatic brain injuries among cyclists from 1988–91 to 1996–99. "However, it is unclear whether this reflects the effectiveness of the mandatory all-age cy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicycle Helmets In Australia
Australia was the first country to make wearing bicycle helmets mandatory. The majority of early statistical data regarding the effectiveness of bicycle helmets originated from Australia. Their efficacy is still a matter of debate. Between 1990 and 1992, Australian states and territories introduced various laws mandating that cyclists wear bicycle helmets while riding after a campaign by various groups including the Royal Australasian College of Surgeons (RACS). History: lead-up to the laws Modern varieties of bicycle helmet first became commercially available from 1975. Industry helmet standards were developed from the 1970s and are still under development. In 1985, the House of Representatives Standing Committee on Transport Safety recommended that cooperation of states and territories should be sought to "review the benefits of bicycle helmet wearing ... and unless there are persuasive arguments to the contrary introduce compulsory wearing of helmets by cyclists on roa ...

Bicycle Helmets In The United States
The requirement to wear bicycle helmets in the United States varies by jurisdiction and by age of the cyclist, for example 21 states and the District of Columbia have statewide mandatory helmet laws for children. 29 US states have no statewide law, and 13 of these states have no such laws in any lower-level jurisdiction either. Importance States began to adopt laws on wearing helmets for bicycle riding in 1987. There are a total of 22 state laws for bicycle helmets and 201 local laws. Each year about 2% of motor vehicle crash deaths are bicyclists. In a majority of bicyclist deaths, the most serious injuries are to the head. Helmet use has been estimated to reduce the odds of head injury by 50%, and the odds of head, face, or neck injury by 33%. Protection Helmet laws reduce fatalities from bicycle accidents by about 15% in the long run. There is no evidence that shows laws requiring children to wear helmets increases adult use. Through 2000, existing helmet laws have saved 130 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicycle Helmet
A bicycle helmet is a type of helmet designed to attenuate impacts to the head of a cyclist in falls while minimizing side effects such as interference with peripheral vision. There is ongoing scientific research into the degree of protection offered by bicycle helmets in the event of an accident, and the effects of helmet wearing on cyclist and motor vehicle driver behaviour. There is active debate over what can be concluded from available studies, and on whether the use of helmets by cyclists should be promoted or mandated, either just for children, or for cyclists of all ages. In particular the debate over bicycle helmet laws has been intense and occasionally bitter, often based not only on differing interpretations of the scientific and other academic literature, but also on differing assumptions and interests of various parties. History History of designs A cycle helmet should generally be light in weight and provide ample ventilation because cycling can be an ...

Rights
Rights are legal, social, or ethical principles of freedom or entitlement; that is, rights are the fundamental normative rules about what is allowed of people or owed to people according to some legal system, social convention, or ethical theory. Rights are of essential importance in such disciplines as law and ethics, especially theories of justice and deontology. Rights are fundamental to any civilization and the history of social conflicts is often bound up with attempts both to define and to redefine them. According to the ''Stanford Encyclopedia of Philosophy'', "rights structure the form of governments, the content of laws, and the shape of morality as it is currently perceived". Definitional issues One way to get an idea of the multiple understandings and senses of the term is to consider different ways it is used. Many diverse things are claimed as rights: There are likewise diverse possible ways to categorize rights, such as: There has been considerable debate a ...

Supply Chain
In commerce, a supply chain is a network of facilities that procure raw materials, transform them into intermediate goods and then final products to customers through a distribution system. It refers to the network of organizations, people, activities, information, and resources involved in delivering a product or service to a consumer. Supply chain activities involve the transformation of natural resources, raw materials, and components into a finished product and delivering the same to the end customer. In sophisticated supply chain systems, used products may re-enter the supply chain at any point where residual value is recyclable. Supply chains link value chains. Suppliers in a supply chain are often ranked by "tier", with first-tier suppliers supplying directly to the client, second-tier suppliers supplying to the first tier, and so on. Overview A typical supply chain begins with the ecological, biological, and political regulation of natural resources, followed by the ...

COVID-19 Pandemic
The COVID-19 pandemic, also known as the coronavirus pandemic, is an ongoing global pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The novel virus was first identified in an outbreak in the Chinese city of Wuhan in December 2019. Attempts to contain it there failed, allowing the virus to spread to other areas of Asia and later worldwide. The World Health Organization (WHO) declared the outbreak a public health emergency of international concern on 30 January 2020, and a pandemic on 11 March 2020. As of , the pandemic had caused more than cases and confirmed deaths, making it one of the deadliest in history. COVID-19 symptoms range from undetectable to deadly, but most commonly include fever, dry cough, and fatigue. Severe illness is more likely in elderly patients and those with certain underlying medical conditions. COVID-19 transmits when people breathe in air contaminated by droplets and ...

Commuting
Commuting is periodically recurring travel between one's place of residence and place of work or study, where the traveler, referred to as a commuter, leaves the boundary of their home community. By extension, it can sometimes be any regular or often repeated travel between locations, even when not work-related. The modes of travel, time taken and distance traveled in commuting varies widely across the globe. Most people in least-developed countries continue to walk to work. The cheapest method of commuting after walking is usually by bicycle, so this is common in low-income countries, but is also increasingly practised by people in wealthier countries for environmental and health reasons. In middle-income countries, motorcycle commuting is very common. The next technology adopted as countries develop is more dependent on location: in more populous, older cities, especially in Eurasia mass transit (rail, bus, etc.) predominates, while in smaller, younger cities, and larg ...
