Hull Classification Symbol
The United States Navy, United States Coast Guard, and United States National Oceanic and Atmospheric Administration (NOAA) use a hull classification symbol (sometimes called hull code or hull number) to identify their ships by type and by individual ship within a type. The system is analogous to the pennant number system that the Royal Navy and other European and Commonwealth navies use. History United States Navy The U.S. Navy began to assign unique Naval Registry Identification Numbers to its ships in the 1890s. The system was a simple one in which each ship received a number which was appended to its ship type, fully spelled out, and added parenthetically after the ship's name when deemed necessary to avoid confusion between ships. Under this system, for example, the battleship ''Indiana'' was USS ''Indiana'' (Battleship No. 1), the cruiser ''Olympia'' was USS ''Olympia'' (Cruiser No. 6), and so on. Beginning in 1907, some ships also were referred to alternatively ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Yottametre
The metre (British spelling) or meter (American spelling; see spelling differences) (from the French unit , from the Greek noun , "measure"), symbol m, is the primary unit of length in the International System of Units (SI), though its prefixed forms are also used relatively frequently. The metre was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole along a great circle, so the Earth's circumference is approximately km. In 1799, the metre was redefined in terms of a prototype metre bar (the actual bar used was changed in 1889). In 1960, the metre was redefined in terms of a certain number of wavelengths of a certain emission line of krypton-86. The current definition was adopted in 1983 and modified slightly in 2002 to clarify that the metre is a measure of proper length. From 1983 until 2019, the metre was formally defined as the length of the path travelled by light in a vacuum in of a second. After the 2019 redef ...

Dow Jones Industrial Average
The Dow Jones Industrial Average (DJIA), Dow Jones, or simply the Dow (), is a stock market index of 30 prominent companies listed on stock exchanges in the United States. The DJIA is one of the oldest and most commonly followed equity indexes. Many professionals consider it to be an inadequate representation of the overall U.S. stock market compared to a broader market index such as the S&P 500. The DJIA includes only 30 large companies. It is price-weighted, unlike stock indices which use market capitalization. Furthermore, the DJIA does not use a weighted arithmetic mean. The value of the index can also be calculated as the sum of the stock prices of the companies included in the index, divided by a factor which is currently () approximately 0.152. The factor is changed whenever a constituent company undergoes a stock split so that the value of the index is unaffected by the stock split. First calculated on May 26, 1896, the index is the second-oldest among U.S. market ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

YM (magazine)
''YM'' was an American teen magazine that began in 1932. The magazine ceased publication in 2004. History The magazine was published for 72 years. It was the oldest girls' magazine in the United States. ''YM'' got its start as two magazines in the 1930s—''Compact'', which was aimed at older teens, and ''Calling All Girls'', which was intended for younger girls and pioneered the signature embarrassing-moments column, "Say Anything". By the late 1960s, the publications merged into ''Young Miss'', a small digest-sized mag. The 1980s saw a change in size to a regular magazine on glossy print (similar to ''Teen'') designed by Randy Dunbar and Mark Borden. Several years later, still another title change (this time to ''Young & Modern'') under Bonnie Fuller's direction as editor-in-chief. The final title change came in 2000 (this time to ''Your Magazine''), though the abbreviation "YM" was the title by which it was commonly referred. In early 2002, then editor-in-chief Christina Kelly ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Yokozuna Monogatari
, or , is the top division of the six divisions of professional sumo. Its size is fixed at 42 wrestlers (''rikishi''), ordered into five ranks according to their ability as defined by their performance in previous tournaments. This is the only division that is featured on NHK's standard live coverage of sumo tournaments. The lower divisions are shown on their satellite coverage, with only the ''makuuchi'' broadcast having bilingual English commentary. ''Makuuchi'' literally means "inside the curtain", a reference to the early period of professional sumo, when there was a curtained-off area reserved for the top ranked wrestlers, to sit before appearing for their bouts. Wrestlers are considered for promotion or demotion in rank before each grand tournament according to their performance in the one previous. Generally, a greater number of wins than losses (''kachi-koshi'') results in a promotion, and the reverse (''make-koshi'') results in demotion. There are stricter criteria ...

Molar Concentration
Molar concentration (also called molarity, amount concentration or substance concentration) is a measure of the concentration of a chemical species, in particular of a solute in a solution, in terms of amount of substance per unit volume of solution. In chemistry, the most commonly used unit for molarity is the number of moles per liter, having the unit symbol mol/L or mol/ dm3 in SI unit. A solution with a concentration of 1 mol/L is said to be 1 molar, commonly designated as 1 M. Definition Molar concentration or molarity is most commonly expressed in units of moles of solute per litre of solution. For use in broader applications, it is defined as amount of substance of solute per unit volume of solution, or per unit volume available to the species, represented by lowercase c: :c = \frac = \frac = \frac. Here, n is the amount of the solute in moles, N is the number of constituent particles present in volume V (in litres) of the solution, and N_\text is the Av ...

Yam (god)
Yam (also ''Yamm''; Semitic: ) is the god of the sea in the Canaanite pantheon. He takes the role of the adversary of Baal in the Ugaritic ''Baal Cycle''. The deity's name derives from the Canaanite word for "Sea", and is one name of the Ugaritic god of Rivers and Sea. Also titled ''ṯpṭ nhr'' (" the Judge of the River"), he is also one of the '' 'ilhm'', or sons of El, the name given to the Levantine pantheon. Of all the gods, despite being the champion of El, Yam holds special hostility against Baal Hadad, son of Dagon. He is a deity of the sea and his palace is in the abyss associated with the depths, or Biblical tehom, of the oceans. Yam is the deity of the primordial chaos and represents the power of the sea, untamed and raging; he is seen as ruling storms and the disasters they wreak, and was an important divinity to the maritime Phoenicians. The gods cast out Yam from the heavenly mountain Sappan (modern Jebel Aqra; ''Sappan'' is cognate to '' Tsephon''). The fi ...

YM2149
The AY-3-8910 is a 3-voice programmable sound generator (PSG) designed by General Instrument in 1978, initially for use with their 16-bit CP1610 or one of the PIC1650 series of 8-bit microcomputers. The AY-3-8910 and its variants were used in many arcade games—Konami's ''Gyruss'' contains five—and pinball machines as well as being the sound chip in the Intellivision and Vectrex video game consoles, and the Amstrad CPC, Oric-1, Colour Genie, Elektor TV Games Computer, MSX, and later ZX Spectrum home computers. It was also used in the Mockingboard and Cricket sound cards for the Apple II and the Speech/Sound Cartridge for the TRS-80 Color Computer. After General Instrument's spinoff of Microchip Technology in 1987, the chip was sold for a few years under the Microchip brand. It was also manufactured under license by Yamaha (with a selectable clock divider pin and a double-resolution and double-rate volume envelope table) as the YM2149F; the Atari ST uses this versi ...
