The motorway is dual three lanes except for junction 1A to junction 3 (which is dual four lanes) a short section in-between the exit and entry highway ramp, slip-roads at junction 4 (which is two lanes in both directions) and also between the slip-roads at junction 9 (in the south-eastbound direction only). An Active Traffic Management system operates on the short section north-westbound from junction 16 (A3400 road, A3400) to the M42 motorway, M42. History London to Great Milton The motorway between London and Oxford was constructed in stages between 1967 and 1974. The first section opened in June 1967, from Handy Cross roundabout, High Wycombe to Stokenchurch (junctions 4–5). In 1969, extending in a southerly direction to Holtspur, Beaconsfield, a temporary junction 2 was opened.

Masters athletes are sometimes known as "veterans" and the European Masters Championships, for instance, is known as "Eurovets". This and other high level events including biennial World Championships cater largely to elite-level athletes, but many masters athletes are novices to athletics and enjoy the camaraderie offered by masters competition at the local, National and International level. Most National governing bodies for track and field hold annual Masters championships. Prestigi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stahlhelm
The ''Stahlhelm'' (German for "''steel helmet''") is a term used to refer to a series of German steel combat helmet designs intended to protect the wearer from common battlefield hazards such as shrapnel. The armies of the great powers began to issue steel helmets during World War I as a result of combat experience and experimentation. The German Army (German Empire), German Army began to replace the boiled leather ''Pickelhaube'' with the ''Stahlhelm'' in 1916. The ''Stahlhelm's'' distinctive ''coal scuttle'' shape, was instantly recognizable and became a common element of propaganda on both sides, like the ''Pickelhaube'' before it. The name was used by ''Der Stahlhelm, Bund der Frontsoldaten, Der Stahlhelm'', a German veterans' organization that existed from 1918 to 1935. After World War II, both East Germany, East and West Germany, West German militaries adopted helmets unrelated to the archetypical German helmet designs from the world wars, but continued to refer to the n ...

SSh-40
The SSh-39 () and SSh-40 (, both from стальной шлем, ''stal'noy shlem'', ) were two similar designs of steel combat helmet designed and used by the Soviet Union's Red Army. They were the main forms of helmet in use during World War II and had only superficial differences between them. History In 1931, soldiers of the Red Army received a small number of steel helmets. They were used during military exercises in 1931. Since 1936, the first standard army helmet, the SSh-36, began to be made for the Red Army. In 1939, camouflage nets (worn over helmets to improve camouflage) began to be made in the USSR. SSh-39 The SSh-39 was of simple, more modern design, and was much easier to manufacture than the SSh-36. The SSh-39 would be the standard design for Soviet helmets for the next 29 years, with only minor changes occurring during that time. It is also the design for the helmet on the Tomb of the Unknown Soldier (Moscow), Tomb of the Unknown Soldier in Moscow. The helm ...

M40 Recoilless Rifle
The M40 recoilless rifle is a portable, crew-served 105 mm recoilless rifle made in the United States. Intended primarily as an anti-tank weapon, it could also be employed in an antipersonnel role with the use of an antipersonnel-tracer flechette round. The bore was commonly described as being 106 mm caliber but is in fact 105 mm; the 106 mm designation was intended to prevent confusion with incompatible 105 mm ammunition from the failed M27. The air-cooled, breech-loaded, single-shot rifle fired fixed ammunition and was used primarily from a wheeled ground mount or M92 ground mount. It was designed for direct firing only, and sighting equipment for this purpose was furnished with each weapon, including an affixed M8C .50 cal spotting rifle. 297 M50 "Ontos" were built as self-propelled light armored tracked anti-tank vehicles. They had six 105 mm M40 recoilless rifles as their main armament, which could be fired in rapid succession against a single ...

M40 Rifle
The M40 rifle is a bolt-action sniper rifle used by the United States Marine Corps. It has had four variants: the M40, M40A1, M40A3, and M40A5. The M40 was introduced in 1966. The changeover to the A1 model was completed in the 1970s, the A3 in the 2000s, and the A5 in 2009. Each M40 is built from a Remington Model 700 bolt-action rifle, and is modified by USMC armorers at Marine Corps Base Quantico, using components from a number of suppliers. New M40A5s are being built, and A1s are upgraded to A3s and A5s as they rotate into the armory for service and repair. The rifles have had many sub-variations in telescopic sights, and smaller user modifications. The M40A5 incorporates a detachable magazine and a threaded barrel to allow for the use of a sound suppressor or another muzzle device. The original M40 was a military type-classified version of the Remington 700; it was factory-made, and had a one-piece wooden Stock (firearms), stock. The M40A1 and A3 switched to fiberglass ...

Mersenne Prime
In mathematics, a Mersenne prime is a prime number that is one less than a power of two. That is, it is a prime number of the form for some integer . They are named after Marin Mersenne, a French Minim friar, who studied them in the early 17th century. If is a composite number then so is . Therefore, an equivalent definition of the Mersenne primes is that they are the prime numbers of the form for some prime . The exponents which give Mersenne primes are 2, 3, 5, 7, 13, 17, 19, 31, ... and the resulting Mersenne primes are 3, 7, 31, 127, 8191, 131071, 524287, 2147483647, ... . Numbers of the form without the primality requirement may be called Mersenne numbers. Sometimes, however, Mersenne numbers are defined to have the additional requirement that should be prime. The smallest composite Mersenne number with prime exponent ''n'' is . Mersenne primes were studied in antiquity because of their close connection to perfect numbers: the Euclid–Eule ...

M-40 (Michigan Highway)
M-40 is a north–south state trunkline highway in the Lower Peninsula of the US state of Michigan. The highway runs from US Highway 12 (US 12) near the Indiana state line in Porter Township north through Paw Paw and Allegan to end in the outskirts of Holland. The current northern end is near Interstate 196 (I-196) at an intersection with US 31/ Business Loop I-196 (BL 196). In between, M-40 runs through mixed agricultural and forest lands and along lakes and rivers through Southwest Michigan. The trunkline was designated by July 1, 1919, along with the rest of the original state highway system along a route that is different that of that of the 21st century. South of Paw Paw, the original M-40 reached Niles and even the Indiana state line for a time. The northern end was extended in stages to Holland. The southern end was shifted in the 1970s, resulting in the modern routing. Route description M-40 starts at an intersection with US 12 in rural Cass ...
