Sicilian Defence, Accelerated Dragon
The Accelerated Dragon (or Accelerated Fianchetto) is a chess opening variation of the Sicilian Defence that begins with the moves: :1. e4 c5 :2. Nf3 Nc6 :3. d4 cxd4 :4. Nxd4 g6 The Accelerated Dragon features an early ...g6 by Black. An important difference between this line and the Dragon is that Black avoids playing ...d7–d6, so that they can later play ...d7–d5 in one move, if possible. Black also avoids the Yugoslav Attack, but since White has not been forced to play Nc3 yet, 5.c4 (the Maróczy Bind) is possible. The Accelerated Dragon generally features a more style of play than many other variations of the Sicilian. Main line One of the main lines continues: 5. Nc3 Bg7 6. Be3 Nf6 7. Bc4 (see diagram). At this point the most important Black continuations are 7...0-0 and 7...Qa5. White should not castle after 7...Qa5, unlike in the Yugoslav Attack. 7... 0-0 is the main line, after which White should proceed with 8. Bb3. If Black plays 8...d6, White usua ...

Bundesstraße 38
''Bundesstraße'' (German for "federal highway"), abbreviated ''B'', is the denotation for 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 of the Transport Ministry. In the German highway system they rank below autobahns, but above the '' Landesstraßen'' and ''Kreisstraßen'' maintained by the federal states and the 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. One distinguishing characteristic between German ''Bundesstraßen'' and ''Autobahnen'' is that there usually is a general 100 km/h (62 mph) ...

XB-38 Flying Fortress
The XB-38 Flying Fortress was a single example conversion of a production B-17E Flying Fortress, testing whether the Allison V-1710 V type engine could be substituted for the standard Wright R-1820 radial engine during early World War II. Design and development The XB-38 was the result of a modification project undertaken by Vega (a subsidiary of Lockheed) on a Boeing B-17 Flying Fortress to fit it with liquid-cooled Allison V-1710-89 V-12 engines. It was meant as an improved version of the B-17, and a variant that could be used if air-cooled Wright R-1820 radial engines became scarce. Completing the modifications took less than a year, and the XB-38 made its first flight on May 19, 1943. Only one prototype was built, and it was developed from an existing B-17 bomber. While the XB-38 delivered a substantially higher top speed, its service ceiling was lower. After a few flights it had to be grounded due to a problem with engine manifold joints leaking exhaust gases. Follow ...

The first car to use the B38 is the BMW i8 hybrid sports coupé, where it is used as a transverse mid-mounted engine. Design The B38 features direct injection, an 11:1 compression ratio, variable valve timing (double-VANOS) and the twin-power turbo turbocharger In an internal combustion engine, a turbocharger (often called a turbo) is a forced induction device that is powered b ...
