English Language
English is a West Germanic language that developed in early medieval England and has since become a English as a lingua franca, global lingua franca. The namesake of the language is the Angles (tribe), Angles, one of the Germanic peoples that Anglo-Saxon settlement of Britain, migrated to Britain after its End of Roman rule in Britain, Roman occupiers left. English is the list of languages by total number of speakers, most spoken language in the world, primarily due to the global influences of the former British Empire (succeeded by the Commonwealth of Nations) and the United States. English is the list of languages by number of native speakers, third-most spoken native language, after Mandarin Chinese and Spanish language, Spanish; it is also the most widely learned second language in the world, with more second-language speakers than native speakers. English is either the official language or one of the official languages in list of countries and territories where English ...

Calamine (mineral)
Calamine is a historic name for an ore of zinc. The name ''calamine'' was derived from ''lapis calaminaris'', a Latin correption of Greek ''cadmia (καδμία)'', the old name for zinc ores in general. The name of the Belgium, Belgian town of Kelmis, ''La Calamine'' in French language, French, which was home to a zinc mine, comes from this. In the 18th and 19th centuries large ore mines could be found near the Germany, German village of Breinigerberg. During the early 19th century it was discovered that what had been thought to be one ore was actually two distinct minerals: * Zinc carbonate ZnCarbon, COxygen, O3 or smithsonite and * Zinc silicate Zn4Silicon, Si2O7(OHydrogen, H)2·H2O or hemimorphite. Although chemically and crystallographically quite distinct, the two minerals exhibit similar massive or botryoidal external form and are not readily distinguished without detailed chemical or physical analysis. The first person to separate the minerals was the Great Britain, Bri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zinc
Zinc is a chemical element; it has symbol Zn and atomic number 30. It is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ( electrowinning). Zinc is an essential trace element for humans, animals, plants and for microorganisms and is necessary for prenatal and postnatal development. It is the second most abundant trace metal in humans after iron, an import ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an sufficiency of disclosure, enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private la ...

William Champion (metallurgist)
William Champion (1709–1789) is credited with patenting a process in Great Britain to distill zinc metal from calamine (mineral), calamine using charcoal in a smelter. Background After Abraham Darby I had left the Bristol Brass Company to form his own new copper works at Coalbrookdale, fellow Quaker Nehemiah Champion took over leadership. Nehemiah had three sons: John (1705–1794); Nehemiah (1709–1782); and the youngest William (1710–1789). Early life and patent As a young man, William Champion toured Europe to learn the art of brass making, returning to become a junior partner in the Bristol Brass Company in 1730. He then experimented for six years to develop a process to create zinc – then known as spelter. Using a scaled-up process similar to that used at the Zawar mines in India where this process was available centuries before William Champion rediscovered it, since the 12th century AD,p. 46, Ancient mining and metallurgy in Rajasthan, S.

Royal National Hospital For Rheumatic Diseases
The Royal National Hospital for Rheumatic Diseases is a small, specialist NHS hospital on the Royal United Hospital (RUH) site in the northwestern outskirts of Bath, England. The hospital was founded in 1738 as a general hospital for the poor in the city centre, where the frontage of its building still reads Royal Mineral Water Hospital. Thus it is known locally as "The Mineral Hospital" or "The Min". The hospital moved to a new building at the RUH site in 2019. History From the 16th century, the needs of the "deserving poor" who came to take the healing waters of the Roman Baths were recognised and they were allowed free use of the waters. This attracted beggars; large numbers of people visited the city but St John's Hospital was only accessible to local residents. Proposals in 1716 for a hospital to receive them were supported by Lady Elizabeth Hastings, Henry Hoare, Joseph Jekyll, William Oliver, Beau Nash and others. The hospital was established in 1738 as The Mineral W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Europe
Central Europe is a geographical region of Europe between Eastern Europe, Eastern, Southern Europe, Southern, Western Europe, Western and Northern Europe, Northern Europe.

Bubonic Plague
Bubonic plague is one of three types of Plague (disease), plague caused by the Bacteria, bacterium ''Yersinia pestis''. One to seven days after exposure to the bacteria, flu-like symptoms develop. These symptoms include fever, headaches, and vomiting, as well as Lymphadenopathy, swollen and painful lymph nodes occurring in the area closest to where the bacteria entered the skin. Acral necrosis, the dark discoloration of skin, is another symptom. Occasionally, swollen lymph nodes, known as "buboes", may break open. The three types of plague are the result of the route of infection: bubonic plague, septicemic plague, and pneumonic plague. Bubonic plague is mainly spread by infected fleas from small animals. It may also result from exposure to the body fluids from a dead plague-infected animal. Mammals such as rabbits, hares, and some cat species are susceptible to bubonic plague, and typically die upon contraction. In the bubonic form of plague, the bacteria enter through the ...
