Body Mass
Human body weight is a person's Mass versus weight, mass or weight. Strictly speaking, body weight is the measurement of weight without items located on the person. Practically though, body weight may be measured with clothes on, but without shoes or heavy accessories such as mobile phones and wallets, and using manual or digital Weighing scale, weighing scales. Excess or reduced body weight is regarded as an indicator of determining a person's health, with body volume measurement providing an extra dimension by calculating the distribution of body weight. Average adult human weight varies by continent, from about in Asia and Africa to about in North America, with men on average weighing more than women. Estimation in children There are a number of methods to estimate weight in children for circumstances (such as emergencies) when actual weight cannot be measured. Most involve a parent or health care provider guessing the child's weight through weight-estimation formulas. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mass Versus Weight
In common usage, the mass of an object is often referred to as its weight, though these are in fact different concepts and quantities. Nevertheless, one object will always weigh more than a second object, if the first object has greater mass, and the two objects are subject to the same gravity (i.e. the same gravitational field, gravitational field strength). In scientific contexts, mass is the amount of "matter" in an object (though "matter" may be difficult to define), whereas weight is the force exerted on an object by gravitation, gravity. In other words, an object with a mass of 1.0 kilogram weighs approximately 9.81 newton (unit), newtons on the surface of the Earth, which is its mass multiplied by the gravitational field strength. The object's weight is less on Mars, where gravity is weaker; more on Saturn, where gravity is stronger; and very small in space, far from significant sources of gravity; but it always has the same mass. Objects on the surface of the Earth have wei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Judo
is an unarmed gendai budō, modern Japanese martial art, Olympic sport (since 1964), and the most prominent form of jacket wrestling competed internationally.『日本大百科全書』電子版【柔道】(CD-ROM version of Encyclopedia Nipponica, "Judo"). Judo was created in 1882 by Kanō Jigorō () as an eclectic martial art, distinguishing itself from its predecessors (primarily Tenjin Shin'yō-ryū, Tenjin Shinyo-ryu jujutsu and Kitō-ryū jujutsu) due to an emphasis on "randori" (, lit. 'free sparring') instead of "kata" (pre-arranged forms) alongside its removal of striking and weapon training elements. Judo rose to prominence for its dominance over Kodokan–Totsuka rivalry, established jujutsu schools in tournaments hosted by the Tokyo Metropolitan Police Department (警視庁武術大会, ''Keishicho Bujutsu Taikai''), resulting in its adoption as the department's primary martial art. A judo practitioner is called a , and the judo uniform is called . The objective of co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latin America
Latin America or * french: Amérique Latine, link=no * ht, Amerik Latin, link=no * pt, América Latina, link=no, name=a, sometimes referred to as LatAm is a large cultural region in the Americas where Romance languages — languages derived from Latin — are predominantly spoken. The term was coined in the nineteenth century, to refer to regions in the Americas that were ruled by the Spanish, Portuguese and French empires. The term does not have a precise definition, but it is "commonly used to describe South America, Central America, Mexico, and the islands of the Caribbean." In a narrow sense, it refers to Spanish America plus Brazil (Portuguese America). The term "Latin America" is broader than categories such as ''Hispanic America'', which specifically refers to Spanish-speaking countries; and ''Ibero-America'', which specifically refers to both Spanish and Portuguese-speaking countries while leaving French and British excolonies aside.

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

Asia
Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area of , about 30% of Earth's total land area and 8.7% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, ...

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pharmacokinetics
Pharmacokinetics (from Ancient Greek ''pharmakon'' "drug" and ''kinetikos'' "moving, putting in motion"; see chemical kinetics), sometimes abbreviated as PK, is a branch of pharmacology dedicated to determining the fate of substances administered to a living organism. The substances of interest include any chemical xenobiotic such as: pharmaceutical drugs, pesticides, food additives, cosmetics, etc. It attempts to analyze chemical metabolism and to discover the fate of a chemical from the moment that it is administered up to the point at which it is completely eliminated from the body. Pharmacokinetics is the study of how an organism affects a drug, whereas pharmacodynamics (PD) is the study of how the drug affects the organism. Both together influence dosing, benefit, and adverse effects, as seen in PK/PD models. Overview Pharmacokinetics describes how the body affects a specific xenobiotic/chemical after administration through the mechanisms of absorption and distribution, as ...

Boxing At The 2004 Summer Olympics
Boxing at the 2004 Summer Olympics took place in the Peristeri Olympic Boxing Hall. The event was only open to men and bouts were contested over four rounds of two minutes each. Five judges scored the fighters in real time and the boxer with the most points at the end was the winner. Three days before the Games opening ceremony the International Olympic Committee announced that Kenyan boxer David Munyasia had tested positive for cathine and has been excluded from the event. Several medalists at the 2004 Olympics, including Amir Khan, Andre Ward, Gennady Golovkin, Yuriorkis Gamboa, and Guillermo Rigondeaux, later went on to become world champions in professional boxing. However, Russian boxers don’t typically turn pro as their government provides them with extensive funding which allows them to keep their “amateur” status and compete at multiple Olympics. The tournament was also Mario Kindelán's final Olympic event before retirement, with a second lightweight gold metal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Judo At The 2004 Summer Olympics
Judo at the 2004 Summer Olympics took place in the Ano Liossia Olympic Hall and featured 368 judoka competing for 14 gold medals with seven different weight categories in both the men's and women's competitions. Japan dominated the event by taking 8 gold and 2 silver medals. Gold and silver medals in each weight class were determined by a single-elimination bracket. There was a repechage for those who are eliminated by one of the eventual semifinalists. Since there are four semifinalists, this means that four of the losers of the round of 32 (i.e., 25%) faced four of the losers from the round of 16 (50%). The winners of these matches faced the four judokas who have lost in the quarterfinals. The winners, then, of these four matches faced each other to narrow the repechage field down to two judokas. Until this stage, the repechage has been segregated into two distinct halves, with each successive competitor facing another one from the same half of the original bracket; but each of ...

Boxing Weight Classes
In boxing, a weight class is a measurement weight range for boxers. The lower limit of a weight class is equal to the upper weight limit of the class below it. The top class, with no upper limit, is called heavyweight in professional boxing and super heavyweightAIBA, ''Technical & Competition Rules'', §1.2 & Appendix K in amateur boxing. A boxing match is usually scheduled for a fixed weight class, and each boxer's weight must not exceed the upper limit. Although professional boxers may fight above their weight class, an amateur boxer's weight must not fall below the lower limit. A nonstandard weight limit is called a catchweight. Weigh-in A boxer who is over the weight limit may strip naked to make the weight if the excess is minimal; otherwise, in a professional bout, one can try again later, typically after losing weight in the interim through dehydration by vigorous exercise in a steam room. If the excess weight is too great, the effort expended trying to "make weight" wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
