Luteinizing Hormone
Luteinizing hormone (LH, also known as luteinising hormone, lutropin and sometimes lutrophin) is a hormone produced by gonadotropic cells in the anterior pituitary gland. The production of LH is regulated by gonadotropin-releasing hormone (GnRH) from the hypothalamus. In females, an acute rise of LH known as an LH surge, triggers ovulation and development of the corpus luteum. In males, where LH had also been called interstitial cell–stimulating hormone (ICSH), it stimulates Leydig cell production of testosterone. It acts synergistically with follicle-stimulating hormone (Follicle-stimulating hormone, FSH). Structure LH is a heteroprotein dimer, dimeric glycoprotein. Each monomeric unit is a glycoprotein molecule; one alpha and one beta subunit make the full, functional protein. Its structure is similar to that of the other glycoprotein hormones, follicle-stimulating hormone (FSH), thyroid-stimulating hormone (TSH), and human chorionic gonadotropin (hCG). The protein dimer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lincoln Highway
The Lincoln Highway is the first transcontinental highway in the United States and one of the first highways designed expressly for automobiles. Conceived in 1912 by Indiana entrepreneur Carl G. Fisher, and formally dedicated October 31, 1913, the Lincoln Highway runs coast-to-coast from Times Square in New York City west to Lincoln Park in San Francisco, originally through 13 states: New York, New Jersey, Pennsylvania, Ohio, Indiana, Illinois, Iowa, Nebraska, Colorado, Wyoming, Utah, Nevada, and California. In 1915, the "Colorado Loop" was removed, and in 1928, a realignment relocated the Lincoln Highway through the northern tip of West Virginia. Thus, there are a total of 14 states, 128 counties, and more than 700 cities, towns and villages through which the highway passed at some time in its history. The first officially recorded length of the entire Lincoln Highway in 1913 was . Over the years, the road was improved and numerous realignments were made, See throughout, bu ...

Chrysler LH Platform
The LH platform served as the basis for the Chrysler Concorde, Chrysler LHS, Chrysler 300M, Dodge Intrepid, Eagle Vision, and the final Chrysler New Yorker. A Plymouth to be called the "Accolade" was planned, but never saw production. The platform pioneered Chrysler's "cab-forward" design; featured on some Chrysler, Dodge, and Eagle cars in the 1990s and early 2000s. Development As the 1990s dawned, Chrysler faced a renewed round of financial troubles. The US economy slipped into a recession following the 1987 Black Monday stock market crash and the Savings and Loan Crisis, but the company's main problems were due to a lack of engineering innovation and careless spending during the years of prosperity in the 1980s. Most of Chrysler's lineup was based on the proven, but dated K-car platform, plus debt accumulated from expensive purchases including Italian automaker Lamborghini along with American Motors, and critics routinely criticized their inability to produce cars that were ...

Lufthansa
Deutsche Lufthansa AG (), commonly shortened to Lufthansa, is the flag carrier of Germany. When combined with its subsidiaries, it is the second- largest airline in Europe in terms of passengers carried.

Le Havre
Le Havre (, ; nrf, Lé Hâvre ) is a port city in the Seine-Maritime department in the Normandy region of northern France. It is situated on the right bank of the estuary of the river Seine on the Channel southwest of the Pays de Caux, very close to the Prime Meridian. Le Havre is the most populous commune of Upper Normandy, although the total population of the greater Le Havre conurbation is smaller than that of Rouen. After Reims, it is also the second largest subprefecture in France. The name ''Le Havre'' means "the harbour" or "the port". Its inhabitants are known as ''Havrais'' or ''Havraises''. The city and port were founded by King Francis I in 1517. Economic development in the Early modern period was hampered by religious wars, conflicts with the English, epidemics, and storms. It was from the end of the 18th century that Le Havre started growing and the port took off first with the slave trade then other international trade. After the 1944 bombings the firm of Auguste ...

LH (DOS Command)
In computing, (abbreviated ) is an internal DOS command in COMMAND.COM that is used to load a program into the upper memory area (UMA) instead of conventional memory. The command was introduced with MS-DOS 5.0 / PC DOS 5.0 in 1991, copying the built-in command earlier introduced with DR DOS 5.0 in 1990. DR DOS 6.0 added support for this naming variant as well in 1991. Overview Due to design of the IBM PC, DOS suffered from what was known as the 640 KB barrier. The size of this memory area, known as conventional memory, was fixed and independent of the amount of system memory actually installed. Various schemes were developed to support extra memory (see also EMS, XMS) and DOS extenders, but conventional memory was still an issue due to compatibility issues. It was a scarce resource as many applications demanded a large part of this basic memory fragment at runtime. Therefore, it was often necessary to move high some TSR programs like the mouse driver or the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lethbridge Hurricanes
The Lethbridge Hurricanes are a Canadian major junior ice hockey team currently members of the Eastern Conference (Central Division) of the Western Hockey League (WHL). The team is based in Lethbridge, Alberta, and play their home games at the ENMAX Centre. History When the Lethbridge Broncos returned to their original home in Swift Current following the 1985–86 season, hockey fans in Lethbridge did not have to wait long for a new team; after just one year out of the WHL, Lethbridge returned to the WHL in 1987–88 when the Calgary Wranglers moved south to become the Hurricanes. The team's crowning achievement came in 1996–97, when the Hurricanes captured their first, and to date only, WHL Championship. The Hurricanes then finished as Memorial Cup runners-up when they lost the title game to the Hull Olympiques. That same year, they also won their division title (only done twice before, in 1989–90 and 1990–91) and the regular season title. In the 2007–08 season, the ...

LH (complexity)
In computational complexity, the logarithmic time hierarchy (LH) is the complexity class of all computational problems solvable in a logarithmic amount of computation time on an alternating Turing machine with a bounded number of alternations. It is a particular case of a bounded alternating Turing machine hierarchy. It is equal to FO and to FO-uniform AC0. The ith level of the logarithmic time hierarchy is the set of languages recognised by alternating Turing machines in logarithmic time with random access Random access (more precisely and more generally called direct access) is the ability to access an arbitrary element of a sequence in equal time or any datum from a population of addressable elements roughly as easily and efficiently as any othe ... and i-1 alternations, beginning with an existential state. LH is the union of all levels. References Complexity classes {{Comp-sci-theory-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Development Of Windows Vista
New product development, Development of Windows Vista occurred over the span of five years, starting in earnest in May 2001, prior to the release of Microsoft's Windows XP operating system, and continuing until November 2006. Microsoft originally expected to ship the new version sometime late in 2003 as a minor step between Windows XP (codenamed "Whistler") and the next planned major release of Windows, code-named "Blackcomb". Vista's original List of Microsoft software codenames, codename, "Longhorn", was an allusion to this plan: While Whistler Blackcomb, Whistler and Blackcomb are large ski resorts in British Columbia, Longhorn is the name of a bar between the two mountains that Whistler's visitors pass to reach Blackcomb. Gradually, Windows "Longhorn" assimilated many of the important new features and technologies slated for "Blackcomb", resulting in the release date being pushed back a few times. Many of Microsoft's developers were also re-tasked with improving the security o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
