A structure is an arrangement and organization of interrelated elements in a material object or system, or the object or system so organized. [1] Material structures include man-made objects such as buildings and machines and natural objects such as biological organisms , minerals and chemicals .
The 7.5 cm KwK 42 L/70 (from 7.5 cm Kampfwagenkanone 42 L/70) was a 7.5 cm calibre German tank gun used on German armoured fighting vehicles in the Second World War. The gun was the armament of the Panther medium tank and two variants of the Jagdpanzer IV self-propelled anti-tank gun .
The 7.5 cm KwK 40 (7.5 cm Kampfwagenkanone [a] 40) was a German 75 mm Second World War era vehicle-mounted gun, used as the primary armament of the German Panzer IV (F2 model onwards) medium tank and the Sturmgeschütz III (F model onwards) and Sturmgeschütz IV assault guns which were used as tank destroyers.
The previous generation of the military calibres used in Europe at the time were 10 to 14 mm (and black powder) as opposed to 7.5 mm of the Schmidt–Rubin ammunition, but the transition was underway in late 1880s (e. g., 8×50mmR Lebel was adopted in 1886 and 7.65×53mm Mauser in 1889). It was one of the first with 7.5 mm copper-jacketed ...
5-over-1 or over-1s, also known as a one-plus-five or a podium building, [1] is a type of multi-family residential building commonly found in urban areas of North America. [ 2 ] [ 3 ] The mid-rise buildings are normally constructed with four or five wood-frame stories above a concrete podium, usually for retail or resident amenity space.
At near-IR wavelengths, the characteristics of the 1.65, 3.1, and 4.53 μm water absorption lines are dependent on the ice temperature and crystal order. [160] The peak strength of the 1.65 μm band as well as the structure of the 3.1 μm band are particularly useful in identifying the crystallinity of water ice. [161] [162]
The dual of a 7-cube is called a 7-orthoplex, and is a part of the infinite family of cross-polytopes.. Applying an alternation operation, deleting alternating vertices of the hepteract, creates another uniform polytope, called a demihepteract, (part of an infinite family called demihypercubes), which has 14 demihexeractic and 64 6-simplex 6-faces.
In genetics, a centimorgan (abbreviated cM) or map unit (m.u.) is a unit for measuring genetic linkage. It is defined as the distance between chromosome positions (also termed loci or markers ) for which the expected average number of intervening chromosomal crossovers in a single generation is 0.01.
