Asphalt
Asphalt, also known as bitumen (, ), is a sticky, black, highly viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or may be a refined product, and is classed as a pitch. Before the 20th century, the term asphaltum was also used. Full text at Internet Archive (archive.org) The word is derived from the Ancient Greek ἄσφαλτος ''ásphaltos''. The largest natural deposit of asphalt in the world, estimated to contain 10 million tons, is the Pitch Lake located in La Brea in southwest Trinidad (Antilles island located on the northeastern coast of Venezuela), within the Siparia Regional Corporation. The primary use (70%) of asphalt is in Road surface, road construction, where it is used as the glue or binder mixed with construction aggregate, aggregate particles to create asphalt concrete. Its other main uses are for bituminous waterproofing products, including production of roofing felt and for sealing flat roofs. In material sciences an ...

PPTC
A resettable fuse or polymeric positive temperature coefficient device (PPTC) is a passive electronic component used to protect against overcurrent faults in electronic circuits. The device is also known as a multifuse or polyfuse or polyswitch. They are similar in function to PTC thermistors in certain situations but operate on mechanical changes instead of charge carrier effects in semiconductors. These devices were first discovered and described by Gerald Pearson at Bell Labs in 1939 and described in US patent #2,258,958.U.S. Patent 2258958. "Conductive device", filed 13 Jul 1939, retrieved 7 mar 2017. Operation A polymeric PTC device is made up of a non-conductive[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marin County Airport
Marin County Airport or Gnoss Field , formerly O56, is a public airport two miles northeast of Novato, California, United States. It covers , and has one runway and one helipad. Most U.S. airports use the same three-letter location identifier for the FAA and IATA, but Marin County Airport/Gnoss Field is DVO to the FAA and NOT to the IATA (which assigned DVO to Francisco Bangoy International Airport in Davao City, Philippines). A plan was unveiled in 2014 to extend the length of Gnoss' runway by 1100', to 4400'. The FAA's final recommendation in 2016 called for a 300-foot extension, which would make Runway 31/13 3600 feet. Public commentary, especially from aviators, was negative. Many pilots contended that the FAA has underestimated the level of activity at Gnoss Field. History The airport was opened by the Wright family just after World War II to serve the thousands of ex-military pilots expected to be flying after the war. The Wrights original privately owned airport had ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UNICOM
A UNICOM (universal communications) station is an air-ground communication facility operated by a non-air traffic control private agency to provide advisory service at uncontrolled aerodromes and airports and to provide various non-flight services, such as requesting a taxi, even at towered airports. It is also known as an ''aeronautical advisory station''. The equivalent European/ICAO service is known as ''(aerodrome) flight information service'', abbreviated as AFIS or FIS. Description UNICOM is employed at airports with a low volume of general aviation traffic and where no control tower is active. UNICOM stations typically use a single communications frequency. Some airfields always offer UNICOM service while others revert to UNICOM procedures only during hours when the control tower is closed. Under this protocol, aircraft may call a non-government ground station to make announcements of their intentions. Pilots who join the frequency later can request field advisories, which m ...

Charles M
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Some Germanic languages, for example Dutch and German, have retained the word in two separate senses. In the particular case of Dutch, ''Karel'' refers to the given name, whereas the noun ''kerel'' means "a bloke, fellow, man". Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (< Old English ''ċeorl''), which developed its dep ...

The Press Democrat
''The Press Democrat'', with the largest circulation in California's North Bay, is a daily newspaper published in Santa Rosa, California. History The newspaper was founded in 1897 by Ernest L. Finley who merged his ''Evening Press'' and Thomas Thompson's ''Sonoma Democrat'' (originally created as a voice for the Democratic Party). Finley also bought the ''Santa Rosa Republican'' in 1927 and merged it with the ''Press Democrat'' in 1948. Ernest L. Finley, his wife Ruth, daughter Ruth, and son-in-law Evert Person owned and published the "PD" between 1897 and 1985. Evert and Ruth Finley Person sold the paper to The New York Times Company in 1985. The most popular feature in the newspaper for many years was Gaye LeBaron's community column, according to a readership survey. LeBaron produced more than 8,000 columns between 1961 and her semi-retirement in 2001, writing on human interest, cultural events, ethnic history and local politics. ''The Press Democrat'' is now owned by Sonom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airfield Traffic Pattern
An airfield traffic pattern is a standard path followed by aircraft when taking off or landing while maintaining visual contact with the airfield. At an airport, the pattern (or circuit) is a standard path for coordinating air traffic. It differs from "straight-in approaches" and "direct climb-outs" in that aircraft using a traffic pattern remain close to the airport. Patterns are usually employed at small general aviation (GA) airfields and military airbases. Many large controlled airports avoid the system unless there is GA activity as well as commercial flights. However, some kind of a pattern may be used at airports in some cases such as when an aircraft is required to go around, but this kind of pattern at controlled airports may be very different in form, shape, and purpose to the standard traffic pattern as used at GA airports. The use of a pattern at airfields is for aviation safety. By using a consistent flight pattern, pilots will know from where to expect other air tr ...

Autopsy
An autopsy (post-mortem examination, obduction, necropsy, or autopsia cadaverum) is a surgical procedure that consists of a thorough examination of a corpse by dissection to determine the cause, mode, and manner of death or to evaluate any disease or injury that may be present for research or educational purposes. (The term "necropsy" is generally reserved for non-human animals). Autopsies are usually performed by a specialized medical doctor called a pathologist. In most cases, a medical examiner or coroner can determine the cause of death. However, only a small portion of deaths require an autopsy to be performed, under certain circumstances. Purposes of performance Autopsies are performed for either legal or medical purposes. Autopsies can be performed when any of the following information is desired: * Determine if death was natural or unnatural * Injury source and extent on the corpse * Manner of death must be determined * Post mortem interval * Determining the deceas ...
