Bundesstraße 39
''Bundesstraße'' (German language, German for "federal highway"), abbreviated ''B'', is the denotation for Germany, German and Austrian national highways. Germany Germany's ''Bundesstraßen'' network has a total length of about 40,000 km. German ''Bundesstraßen'' are labelled with rectangular yellow signs with black numerals, as opposed to the white-on-blue markers of the ''Autobahn'' controlled-access highways. ''Bundesstraßen'', like autobahns, are maintained by the Federal agency (Germany), federal agency of the Federal Ministry of Transport, Building and Urban Development, Transport Ministry. In the German highway system they rank below autobahns, but above the ''Landesstraßen'' and ''Kreisstraßen'' maintained by the States of Germany, federal states and the Districts of Germany, districts respectively. The numbering was implemented by law in 1932 and has overall been retained up to today, except for those roads located in the former eastern territories of Germany. ...

B39 Nuclear Bomb
The Mark 39 nuclear bomb and W39 nuclear warhead were versions of an American thermonuclear weapon, which were in service from 1957 to 1966. The Mark 39 design was a thermonuclear bomb (see Teller-Ulam design) and had a yield of 3.8 megatons. It weighed 6,500–6,750 pounds (2,950–3,060 kilograms), and was about 11 feet, 8 inches long (3.556 meters) with a diameter of 2 feet, 11 inches (88.9 centimeters).The design is an improved Mark 15 nuclear bomb design (the TX-15-X3 design and Mark 39 Mod 0 were the same design). The Mark 15 was the first lightweight US thermonuclear bomb. The W39 warhead is in diameter and long, with a weight of to . It was used on the SM-62 Snark missile, PGM-11 Redstone short-range ballistic missile, and in the B-58 Hustler weapons pod. Goldsboro Incident Two Mark 39 nuclear bombs that were carried by a B-52 Stratofortress broke up in the air and crashed near Goldsboro, North Carolina on January 24, 1961. According to Parker F. Jones, a supe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
XB-39 Superfortress
The Boeing XB-39 Superfortress was a United States prototype bomber aircraft, a single example of the B-29 Superfortress converted to fly with alternative powerplants. It was intended to demonstrate that the B-29 could still be put into service even if the first choice of engine, the air-cooled Wright R-3350 radial engine, ran into development or production difficulties. Design and development Starting life as the first YB-29 delivered to the United States Army Air Forces, it was sent in November 1943 to the Fisher Body Aircraft Development Section of General Motors to be converted to use Allison V-3420-17 liquid-cooled W24 (twin- V12, common crankcase) inline engines.''Flying Magazine,''August 1945, p. 51. Fisher was chosen for the modification as it was familiar with the engine, as it was to power the P-75 Eagle that they were then developing. Testing on it began in early 1944. Further development of the engine and the aircraft was delayed by a series of changes in the plann ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Submarine B-39
''B-39'' was a Project 641 () diesel-electric attack submarine of the Soviet Navy. The "B" (actually " Б") in her designation stands for большая (''bolshaya'', "large")—Foxtrots were the Soviet Navy's largest non-nuclear submarines. In 2005, ''B-39'' became a museum ship on display at the Maritime Museum of San Diego, California, United States. In October 2021 the decision was made to withdraw the deteriorating submarine from the collection and scrap it. History Service history Her keel was laid down on 9 February 1962 at the Admiralty Shipyard in Leningrad (now known as Saint Petersburg). She was launched on 15 April 1967 and commissioned on 28 December 1967. Transferred to the 9th Submarine Squadron of the Pacific Fleet, ''B-39'' was homeported in Vladivostok. She conducted patrols and stalked U.S. warships throughout the North Pacific, along the coast of the United States and Canada, and ranging as far as the Indian Ocean and the Arctic Ocean.

HLA-B39
HLA-B39 (B39) is an HLA- B serotype. The serotype identifies the more common HLA-B*39 gene products. B39 is a split antigen of the broad antigen B16, and is a sister type of B38. B39 is most commonly found on the west pacific rim, in Japan and highest frequency in the new world. In Europe it is found in Scandinavia and Northern Russia. Serotype The serology for the most common B39 alleles, B*3901 and B*3906 is good, but some allele products are not well detected. Given the differential involvement of these alleles in disease testing should involve high resolution typing. Alleles Disease B39 is suggested as a factor in Takayasu's arteritis and gallstones in Mexico. Osteoarticular complications of brucellosis appear to be associated with B39. An association with spondylarthropathies and psoriatic arthritis was observed in several studies. Psoriatic arthritis appears to be linked to MICA-A9 which tightly linked to HLA-B39. B39 also appears to be involved in the Fishe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
