DAB
Digital radio is the use of digital technology to transmit or receive across the radio spectrum. Digital transmission by radio waves includes digital broadcasting, and especially digital audio radio services. Types In digital broadcasting systems, the analog audio signal is digitized, compressed using an audio coding format such as AAC+ ( MDCT) or MP2, and transmitted using a digital modulation scheme. The aim is to increase the number of radio programs in a given spectrum, to improve the audio quality, to eliminate fading problems in mobile environments, to allow additional datacasting services, and to decrease the transmission power or the number of transmitters required to cover a region. However, analog radio (AM and FM) is still more popular and listening to radio over IP (Internet Protocol) is growing in popularity. In 2012 four digital wireless radio systems are recognized by the International Telecommunication Union: the two European systems Digital Audio Broa ...

Dictionary Of American Biography
The ''Dictionary of American Biography'' was published in New York City by Charles Scribner's Sons under the auspices of the American Council of Learned Societies (ACLS). History The dictionary was first proposed to the Council in 1920 by historian Frederick Jackson Turner. The first edition was published in 20 volumes from 1928 to 1936, appearing at a rate of two or three volumes per year. These 20 volumes contained 15,000 biographies. In 1946, the 20 volumes were released as a ten-volume set, with each of the ten volumes divided into two parts (Part 1 and Part 2) corresponding to two volumes of the first edition combined into one, the page numbering of the first edition being retained. The ACLS appealed to Adolph Ochs, publisher of ''The New York Times'', for funding. He loaned the Council $50,000 per year for 10 years. Ochs exercised no editorial control. The dictionary included no biographies of the living, and some period of residence in the United States was required ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Dab
The common dab (''Limanda limanda'') is an edible flatfish of the family Pleuronectidae. It is a demersal fish native to shallow seas around Northern Europe, in particular the North Sea, where it lives on sandy bottoms down to depths of about . It can reach in length and can weigh up to , though most specimens grow no longer than . Taxonomy and nomenclature The etymology of the name ''dab'' is unclear, but the modern English use seems to originate from the Middle English ''dabbe''. It is first recorded in the late 16th century. The common dab was first named ''Pleuronectes limanda'' by Carl Linnaeus in the 1758 10th edition of ''Systema Naturae''. It has also been moved to other genera, including ''Liopsetta'', and is now known as ''Limanda limanda''. Identification The common dab has a similar appearance to both the plaice and the flounder, and similarly has both its eyes normally on the right-hand side of its body. The upper surface is usually pale brown in colour with s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Motorcycle Trials
Motorcycle trials, also known as observed trials, often called simply trial/s (with or without the plural "s"), is a non-speed event on specialized motorcycles. The sport is most popular in the United Kingdom and Spain, though there are participants around the globe. Modern trials motorcycles are distinctive in that they have evolved to become extremely lightweight, lack seating (they are designed to be ridden standing up) and have suspension travel that is short, relative to a motocross or enduro motorcycle. Motorcycle trials is often utilized by competitors in other motorcycle sports (such as enduro, motocross or road racers) as a way to cross-train, as trials requires fine throttle, balance, and machine control. Characteristics The event is split into sections where a competitor rides through an obstacle course while attempting to avoid touching the ground with their feet. The obstacles in the course may be of natural or constructed elements. In all sections, regardless of co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hash Oil
Hash oil or cannabis oil, is an oleoresin obtained by the extraction of cannabis or hashish. It is a cannabis concentrate containing many of its resins and terpenes – in particular, tetrahydrocannabinol (THC), cannabidiol (CBD), and other cannabinoids. Hash oil is usually consumed by smoking, vaporizing or eating. Preparations of hash oil may be solid or colloidal depending on both production method and temperature and are usually identified by their appearance or characteristics. Color most commonly ranges from transparent golden or light brown, to tan or black. There are various extraction methods, most involving a solvent, such as butane or ethanol. Hash oil is an extracted cannabis product that may use any part of the plant, with minimal or no residual solvent. It is generally thought to be indistinct from traditional hashish, according to the 1961 UN Single Convention on Narcotic Drugs (Schedule I and IV), as it is "the separated resin, whether crude or purified, obt ...

Daytona Beach International Airport
Daytona Beach International Airport is a county-owned airport located three miles (5 km) southwest of Daytona Beach, next to Daytona International Speedway, in Volusia County, Florida, United States. The airport has 3 runways, a six-gate domestic terminal, and an international terminal. Daytona Beach is the headquarters of Embry-Riddle Aeronautical University. History The Beach Daytona Beach’s beach was known for having a smooth, hard, and relatively clean surface for motor vehicles which would frequently race on it. Pilots soon realized the effectiveness of the compact sand and began using the beach as a runway. Hangars were built later and aircraft service was provided on beach. This former airport is one of only two beach airports that were successful. The other, Old Orchard Beach in Maine, was the starting point for at least five transatlantic flights during the 1920s and 1930s. The first flight on the beach was in 1906 by Charles K. Hamilton, using Israel Ludlow's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dab (dance)
Dabbing, or the dab, is a gesture in which a person drops their head into the bent crook of a slanted, upward angled arm, while raising the opposite arm out straight in a parallel direction. The move looks similar to someone sneezing into the crook of their elbow. Since 2015, dabbing has been used as a gesture of triumph or playfulness, becoming a youthful fad and Internet meme. Origins Before the term "dab" was coined, the move had been a feature of Japanese popular culture for decades. A popular example is the 1990s anime series ''Dragon Ball Z'', where the character Gohan (as The Great Saiyaman) occasionally performs the dab move. It is known as a "Sentai move" in Japan, from its popular use in the ''Super Sentai'' and ''Kamen Rider'' tokusatsu superhero series since the 1970s (localised as ''Power Rangers'' and '' Masked Rider'' in the 1990s). It resurfaced again in 1993, seen in one of Janet Jackson's dance videos for the song "If", which also had strong Asian influe ...

Stereotype (printing)
In printing, a stereotype, stereoplate or simply a stereo, is a solid plate of type metal, cast from a papier-mâché or plaster mould taken from the surface of a forme of type. The mould was known as a '' flong''. Background In the days of set movable type, printing involved placing individual letters (called type) plus other elements (including leading and furniture) into a block called a chase. Cumulatively, this full setup for printing a single page was called a forme. Ink was then applied to the forme, pressed against paper and a printed page was made. This process of creating formes was labour-intensive, costly and prevented printers from using their type, leading, furniture and chases for other work. Furthermore, printers who underestimated demand would be forced to reset the type for subsequent print runs. ... while Nathaniel Hawthorne's publishers assumed that ''The Scarlet Letter'' (1850) would do well, printing an uncharacteristically large edition of 2,500 co ...

4-Dimethylaminoazobenzene
Methyl yellow, or C.I. 11020, is an organic compound with the formula C6H5N2C6H4N(CH3)2. It is an azo dye derived from dimethylaniline. It is a yellow solid. According to X-ray crystallography, the C14N3 core of the molecule is planar. It is used as a dye for plastics and may be used as a pH indicator. In aqueous solution at low pH, methyl yellow appears red. Between pH 2.9 and 4.0, methyl yellow undergoes a transition, to become yellow above pH 4.0. Safety It is a possible carcinogen. As "butter yellow", the agent had been used as a food additive in butter and margarine before its toxicity was recognized. History Butter yellow was synthesized by Peter Griess in the 1860s at the Royal College of Chemistry in London. The dye was used to dye butter in Germany and other parts of the world during the latter half of the 19th century and the beginning of the 20th before being phased out in the 1930s and 40s. It was in the 1930s that research led by Riojun Kinosita showed the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
