Unincorporated Area
An unincorporated area is a parcel of land that is not governed by a local general-purpose municipal corporation. (At p. 178.) They may be governed or serviced by an encompassing unit (such as a county) or another branch of the state (such as the military). There are many unincorporated communities and areas in the United States and Canada, but many countries do not use the concept of an unincorporated area.

Calvert City
Calvert City is a home rule-class city in Marshall County, Kentucky, United States. The population was 2,514 at the 2020 census. History Calvert City was named for Potilla Willis Calvert. He built his home, Oak Hill, in 1860 and around a decade later gave a portion of his land to a new railroad, specifying that a station be built near his home.Rennick, Robert. ''Kentucky Place Names'', p. 46. University Press of Kentucky (Lexington), 1987. Accessed 24 July 2013. That station served as the starting point of the town, which was incorporated on March 18, 1871. The railroad station and post office long favored the shorter Calvert, but the Board on Geographic Names reversed its earlier decision in 1957 and switched to the longer form. By 1896, Calvert City was known as a sundown town, where African Americans were not allowed to reside. By 1908, the rest of Marshall County had also expelled its African American residents. During the Ohio River flood of 1937, Calvert City's busin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olefin Metathesis
In organic chemistry, Olefin Metathesis or Alkene Metathesis is an organic reaction that entails the redistribution of fragments of alkenes (olefins) by the Bond cleavage, scission and regeneration of carbon-carbon double bonds. Because of the relative simplicity of olefin metathesis, it often creates fewer undesired by-products and hazardous wastes than alternative organic reactions. For their elucidation of the reaction mechanism and their discovery of a variety of highly active Catalysis, catalysts, Yves Chauvin, Robert H. Grubbs, and Richard R. Schrock were collectively awarded the 2005 Nobel Prize in Chemistry. Catalysts The reaction requires catalysis, metal catalysts. Most commercially important processes employ heterogeneous catalysis, heterogeneous catalysts. The heterogeneous catalysts are often prepared by in-situ activation of a metal halide (MClx) using organoaluminium or organotin compounds, e.g. combining MClx–EtAlCl2. A typical catalyst support is alumina. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

California Institute Of Technology
The California Institute of Technology (branded as Caltech) is a private research university in Pasadena, California, United States. The university is responsible for many modern scientific advancements and is among a small group of institutes of technology in the United States that are devoted to the instruction of pure and applied sciences. The institution was founded as a preparatory and vocational school by Amos G. Throop in 1891 and began attracting influential scientists such as George Ellery Hale, Arthur Amos Noyes, and Robert Andrews Millikan in the early 20th century. The vocational and preparatory schools were disbanded and spun off in 1910, and the college assumed its present name in 1920. In 1934, Caltech was elected to the Association of American Universities, and the antecedents of NASA's Jet Propulsion Laboratory, which Caltech continues to manage and operate, were established between 1936 and 1943 under Theodore von Kármán. Caltech has six academic divisi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemist
A chemist (from Greek ''chēm(ía)'' alchemy; replacing ''chymist'' from Medieval Latin ''alchemist'') is a graduated scientist trained in the study of chemistry, or an officially enrolled student in the field. Chemists study the composition of matter and its properties. Chemists carefully describe the properties they study in terms of quantities, with detail on the level of molecules and their component atoms. Chemists carefully measure substance proportions, chemical reaction rates, and other chemical properties. In Commonwealth English, pharmacists are often called chemists. Chemists use their knowledge to learn the composition and properties of unfamiliar substances, as well as to reproduce and synthesize large quantities of useful naturally occurring substances and create new artificial substances and useful processes. Chemists may specialize in any number of Chemistry#Subdisciplines, subdisciplines of chemistry. Materials science, Materials scientists and metallurgists sha ...

Jackson Purchase
The Jackson Purchase, also known as the Purchase Region or simply the Purchase, is a region in the U.S. state of Kentucky bounded by the Mississippi River to the west, the Ohio River to the north, and the Tennessee River to the east. Jackson's Purchase also included all of Tennessee west of the Tennessee River. In modern usage, however, the term refers only to the Kentucky portion of the Jackson Purchase.

On October 19, 1818, the two sides agreed to the transfer by signing the Treaty of Tuscaloosa.
