Office Buildings Completed In 1991
An office is a space where the employees of an organization perform administrative work in order to support and realize the various goals of the organization. The word "office" may also denote a position within an organization with specific duties attached to it (see officer or official); the latter is an earlier usage, as "office" originally referred to the location of one's duty. In its adjective form, the term "office" may refer to business-related tasks. In law, a company or organization has offices in any place where it has an official presence, even if that presence consists of a storage silo. For example, instead of a more traditional establishment with a desk and chair, an office is also an architectural and design phenomenon, including small offices, such as a bench in the corner of a small business or a room in someone's home (see small office/home office), entire floors of buildings, and massive buildings dedicated entirely to one company. In modern terms, an offic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Tallest Buildings By U
A list is a set of discrete items of information collected and set forth in some format for utility, entertainment, or other purposes. A list may be memorialized in any number of ways, including existing only in the mind of the list-maker, but lists are frequently written down on paper, or maintained electronically. Lists are "most frequently a tool", and "one does not ''read'' but only ''uses'' a list: one looks up the relevant information in it, but usually does not need to deal with it as a whole".Lucie Doležalová,The Potential and Limitations of Studying Lists, in Lucie Doležalová, ed., ''The Charm of a List: From the Sumerians to Computerised Data Processing'' (2009). Purpose It has been observed that, with a few exceptions, "the scholarship on lists remains fragmented". David Wallechinsky, a co-author of ''The Book of Lists'', described the attraction of lists as being "because we live in an era of overstimulation, especially in terms of information, and lists help us ...

Church Of Christ, Scientist
The Church of Christ, Scientist was founded in 1879 in Boston, Massachusetts, by Mary Baker Eddy, author of '' Science and Health with Key to the Scriptures,'' and founder of Christian Science. The church was founded "to commemorate the word and works of Christ Jesus" and "reinstate primitive Christianity and its lost element of healing". In the early decades of the 20th century, Christian Science churches were founded in communities around the world, though in the last several decades of that century, there was a marked decline in membership, except in Africa, where there has been growth. Headquartered in Boston, the church does not officially report membership, and estimates as to worldwide membership range from under 100,000 to about 400,000. In 2010, there were 1,153 churches in the United States. History The church was incorporated by Mary Baker Eddy in 1879, following a claimed personal healing in 1866, which she said resulted from reading the Bible. The Bible and Eddy's ...

Iowa Caucuses
The Iowa caucuses are quadrennial electoral events for the Democratic and Republican parties in the U.S. state of Iowa. Unlike primary elections, where registered voters cast ballots at polling places on election day, Iowa caucuses are meetings where voters gather to discuss and select candidates for their registered party. Political parties hold the caucuses, in contrast to most state-run primaries. Both presidential and midterm elections in Iowa use caucuses. The caucuses are also held to select delegates to county conventions and party committees, among other party activities. The Iowa caucuses are noteworthy as the first major contest of the United States presidential primary season. Although caucus-goers have been unrepresentative of the nation's overall demographic, caucuses are still seen by some as a strong indicator of how a presidential candidate will do in later contests. Candidates who do poorly in the Iowa caucus frequently drop out in the following days ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Des Moines Register
''The Des Moines Register'' is the daily morning newspaper of Des Moines, Iowa, United States. History Early period The first newspaper in Des Moines was the ''Iowa Star''. In July 1849, Barlow Granger began the paper in an abandoned log cabin by the junction of the Des Moines and Raccoon River. In 1854, ''The Star'' became the ''Iowa Statesman'' which was also a Democratic paper. In 1857, ''The Statesman'' became the ''Iowa State Journal'', which published three times per week. In 1870, ''The Iowa State Journal'' became the ''Iowa State Leader'' as a Democratic newspaper, which competed with pro- Republican ''Iowa Daily State Register'' for the next 32 years. In 1902, George Roberts bought the ''Register'' and ''Leader'' and merged them into a morning newspaper. In 1903, Des Moines banker Gardner Cowles, Sr. purchased the ''Register and Leader''. The name finally became ''The Des Moines Register'' in 1915. (Cowles also acquired the '' Des Moines Tribune'' in 1908. The ...

Sulfur
Sulfur ( American spelling and the preferred IUPAC name) or sulphur ( Commonwealth spelling) is a chemical element; it has symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with the chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature. Sulfur is the tenth most abundant element by mass in the universe and the fifth most common on Earth. Though sometimes found in pure, native form, sulfur on Earth usually occurs as sulfide and sulfate minerals. Being abundant in native form, sulfur was known in ancient times, being mentioned for its uses in ancient India, ancient Greece, China, and ancient Egypt. Historically and in literature sulfur is also called brimstone, which means "burning stone". Almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum.. Downloahere Th ...

Redox
Redox ( , , reduction–oxidation or oxidation–reduction) is a type of chemical reaction in which the oxidation states of the reactants change. Oxidation is the loss of electrons or an increase in the oxidation state, while reduction is the gain of electrons or a decrease in the oxidation state. The oxidation and reduction processes occur simultaneously in the chemical reaction. There are two classes of redox reactions: * Electron transfer, Electron-transfer – Only one (usually) electron flows from the atom, ion, or molecule being oxidized to the atom, ion, or molecule that is reduced. This type of redox reaction is often discussed in terms of redox couples and electrode potentials. * Atom transfer – An atom transfers from one Substrate (chemistry), substrate to another. For example, in the rusting of iron, the oxidation state of iron atoms increases as the iron converts to an oxide, and simultaneously, the oxidation state of oxygen decreases as it accepts electrons r ...

Verdigris
Verdigris () is a common name for any of a variety of somewhat toxic copper salt (chemistry), salts of acetic acid, which range in colour from green to a blue-green, bluish-green depending on their chemical composition.H. Kühn, Verdigris and Copper Resinate, in Artists' Pigments. A Handbook of Their History and Characteristics, Vol. 2: A. Roy (Ed.) Oxford University Press 1993, p. 131 – 158 Once used as a medicine and pharmaceutical preparation, verdigris occurs naturally, creating a patina on copper, bronze, and brass, and is the main component of a historic green pigment used for artistic purposes from antiquity until the late 20th century, including in Easel, easel painting, polychromatic sculptures, and illumination of maps. However, due to its instability, its popularity declined as other green pigments became readily available. The instability of its appearance stems from its Hydration number, hydration level and Base (chemistry), basicity, which change as the pigment inte ...
