Mannheim Water Tower
The Water Tower (German: ''Wasserturm'') is a well-known landmark of Mannheim, Germany. The water tower was built from 1886 to 1889 on the present Frederick Square (''Friedrichsplatz'') by Gustav Halmhuber. The tower, which is 60 meters high and 19 meters in diameter, was Mannheim's first urban water tower. It initially had to meet with the required standards as a drinking water supply while maintaining steady water pressure. After the construction of the higher Luzenberg water tower in 1909, the Mannheim water tower served as an aboveground water tank until 2000. History Early history Since Mannheim lies on the Rhine Valley, the groundwater is not very deep under the earth's surface and is therefore often of poor quality. Consequently, during the reign of Elector Charles Louis (1680), the merchant Helferich Geil suggested channeling "mountain water from Rohrbach" (now a district of Heidelberg) to Mannheim. Until the 19th century, the electoral court's water requirements w ...

Cooper (profession)
A cooper is a person trained to make wooden casks, barrels, vats, buckets, tubs, troughs and other similar containers from timber staves that were usually heated or steamed to make them pliable. Journeymen coopers also traditionally made wooden implements, such as rakes and wooden-bladed shovels. In addition to wood, other materials, such as iron, were used in the manufacturing process. The trade is the origin of the surname Cooper. Etymology The word "cooper" is derived from Middle Dutch or Middle Low German ''kūper'' 'cooper' from ''kūpe'' 'cask', in turn from Latin ''cupa'' 'tun, barrel'. Everything a cooper produces is referred to collectively as ''cooperage.'' A cask is any piece of cooperage containing a bouge, bilge, or bulge in the middle of the container. A barrel is a type of cask, so the terms "barrel-maker" and "barrel-making" refer to just one aspect of a cooper's work. The facility in which casks are made is also referred to as a cooperage. As a name In ...

Government Bond
A government bond or sovereign bond is a form of bond issued by a government to support public spending. It generally includes a commitment to pay periodic interest, called coupon payments'','' and to repay the face value on the maturity date. For example, a bondholder invests $20,000, called face value or principal, into a 10-year government bond with a 10% annual coupon; the government would pay the bondholder 10% interest each year and repay the $20,000 original face value at the date of maturity (i.e. after 10 years). Government bonds can be denominated in a foreign currency or the government's domestic currency. Countries with less stable economies tend to denominate their bonds in the currency of a country with a more stable economy (i.e. a hard currency). When governments with less stable economies issue bonds, there is a possibility they will be unable to repay bondholders, resulting in a default. All bonds carry a default risk.

Benjamin Thompson
Sir Benjamin Thompson, Count Rumford, FRS (german: Reichsgraf von Rumford; March 26, 1753August 21, 1814) was an American-born British physicist and inventor whose challenges to established physical theory were part of the 19th-century revolution in thermodynamics. He served as lieutenant-colonel of the King's American Dragoons, part of the British Loyalist forces, during the American Revolutionary War. After the end of the war he moved to London, where his administrative talents were recognized when he was appointed a full colonel, and in 1784 he received a knighthood from King George III.

Typhus
Typhus, also known as typhus fever, is a group of infectious diseases that include epidemic typhus, scrub typhus, and murine typhus. Common symptoms include fever, headache, and a rash. Typically these begin one to two weeks after exposure. The diseases are caused by specific types of bacterial infection. Epidemic typhus is due to '' Rickettsia prowazekii'' spread by body lice, scrub typhus is due to '' Orientia tsutsugamushi'' spread by chiggers, and murine typhus is due to '' Rickettsia typhi'' spread by fleas. Vaccines have been developed, but none are commercially available. Prevention is achieved by reducing exposure to the organisms that spread the disease. Treatment is with the antibiotic doxycycline. Epidemic typhus generally occurs in outbreaks when poor sanitary conditions and crowding are present. While once common, it is now rare. Scrub typhus occurs in Southeast Asia, Japan, and northern Australia. Murine typhus occurs in tropical and subtropical areas o ...

Suspended Solids
Suspended solids refers to small solid particles which remain in suspension in water as a colloid or due to motion of the water. Suspended solids can be removed by sedimentation if their size or density is comparatively large, or by filtration. It is used as one indicator of water quality and of the strength of sewage, or wastewater in general. It is an important design parameter for sewage treatment processes. It is sometimes abbreviated SS, but is not to be confused with settleable solids, also abbreviated SS, which contribute to the blocking of sewer pipes. Explanation Suspended solids are important as pollutants and pathogens are carried on the surface of particles. The smaller the particle size, the greater the total surface area per unit mass of particle in grams, and so the higher the pollutant load that is likely to be carried. Removal Removal of suspended solids is generally achieved through the use of sedimentation and/or water filters (usually at a municip ...

Guild
A guild ( ) is an association of artisans and merchants who oversee the practice of their craft/trade in a particular area. The earliest types of guild formed as organizations of tradesmen belonging to a professional association. They sometimes depended on grants of letters patent from a monarch or other ruler to enforce the flow of trade to their self-employed members, and to retain ownership of tools and the supply of materials, but were mostly regulated by the city government. A lasting legacy of traditional guilds are the guildhalls constructed and used as guild meeting-places. Guild members found guilty of cheating the public would be fined or banned from the guild. Typically the key "privilege" was that only guild members were allowed to sell their goods or practice their skill within the city. There might be controls on minimum or maximum prices, hours of trading, numbers of apprentices, and many other things. These rules reduced free competition, but sometimes mainta ...
