	Business-to-government Business-to-government (B2G),Market Business NewsWhat is B2G or business-to-government? Definition and examples accessed 31 August 2020 also known as business-to-administration (B2A), refers to trade between the business sector as a supplier and a government body as a customer. Public-sector organizations generally post tenders in the form of requests-for-proposals, requests-for-information, requests-for-quotations, and sources-sought, to which private suppliers respond. Business-to-government networks provide a platform for businesses to bid on government opportunities that are presented as solicitations, in the form of requests-for-proposals, through a reverse auction.

	Haplogroup B (mtDNA) In human mitochondrial genetics, haplogroup B is a human mitochondrial DNA (mtDNA) haplogroup. Origin Haplogroup B is believed to have arisen in Asia some 50,000 years before present. Its ancestral haplogroup was haplogroup R. The greatest variety of haplogroup B is in China. It is therefore likely that it underwent its earliest diversification in mainland East or South East Asia.Yong-Gang Yao et al. 2001Phylogeographic Differentiation of Mitochondrial DNA in Han ChineseAm J Hum Genet. 2002 March; 70(3): 635–651 Distribution Basal B was found in Upper Paleolithic Tianyuan man. Haplogroup B is now most common among populations native to Southeast Asia, as well as speakers of Sino-Tibetan languages and Austronesian languages. A subclade of B4b (which is sometimes labeled B2) is one of five haplogroups found among the indigenous peoples of the Americas, the others being A, C, D, and X. Because the migration to the Americas by the ancestors of indigenous Americans is gener ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Sidecar World Championship FIM Sidecar World Championship is the international sidecar racing championship. It is the only remaining original FIM road racing championship class that started in 1949. It was formerly named Superside when the sidecars moved from being part of Grand Prix Motorcycles racing to being support events for the Superbike World Championship. In 2010 the FIM took over the management of the series from the Superside promoters, and the championship was called "FIM Sidecar World Championship". However, the FIM still uses the word Superside for promotion purposes, despite the demise of the Superside promoters. The championship is raced over a number of rounds at circuits mainly in Europe, although other venues have been included in United States (Monterey), South Africa at Kyalami and Australia's Phillip Island. History Formative years When the sidecar world championships began in 1949, they were dominated by unambiguous, orthodox outfits where a sidecar was attached to a conventional sol ...

picture info	Brantly B-2A The Brantly B-2 is an American two-seat light helicopter produced by the Brantly Helicopter Corporation. Design and development After the failure of his first design, the Brantly B-1, Newby O. Brantly decided to design a simpler and less complicated helicopter for the private buyer. The B-2 had a single main rotor and an anti-torque tail rotor and first flew on 21 February 1953. This was followed by an improved second prototype that first flew on 14 August 1956. The B-2A was introduced with a modified cabin, and the B-2B had a larger 180 hp fuel-injected engine. The B-2B has a three-bladed articulated main rotor and an all-metal fuselage, it can be operated with skid, wheel or float landing gear. The piston engine is fitted vertically in the fuselage behind the cabin. Operational history The basic design has remained in production for over 50 years. The United States Army ordered five B-2s (designated the YHO-3) to be evaluated in the Light Observation Helicopter competiti ...

picture info	Northrop-Grumman B-2A Spirit The Northrop (later Northrop Grumman) B-2 Spirit, also known as the Stealth Bomber, is an American heavy strategic bomber, featuring low-observable stealth technology designed to penetrate dense anti-aircraft defenses. A subsonic flying wing with a crew of two, the plane was designed by Northrop, later Northrop Grumman, and produced from 1987 to 2000. The bomber can drop conventional and thermonuclear weapons, such as up to eighty Mk 82 JDAM GPS-guided bombs, or sixteen B83 nuclear bombs. The B-2 is the only acknowledged aircraft that can carry large air-to-surface standoff weapons in a stealth configuration. Development began under the Advanced Technology Bomber (ATB) project during the Carter administration, which cancelled the Mach 2-capable B-1A bomber in part because the ATB showed such promise. But development difficulties delayed progress and drove costs up. Ultimately, the program produced 21 B-2s at an average cost of $2.13 billion (in 1997 dollars), includin ...
