Dolon (air base)

Dolon (also known as Chagan and Semipalitinsk Dolon) is an air base in SemipalatinskKazakhstan that served as a major Cold War bomber base with significant tarmac space and over 50 revetments. Dolon Southwest, a former airfield 32 km to the south, no longer exists.

In 1955, Dolon was one of only six Soviet bases capable of handling the Myasishchev M-4 (Bison) bomber. The 79th Heavy Bomber Aviation Division was created at Dolon in 1957. The Tupolev Tu-160 (Blackjack) was temporarily deployed to Dolon in the late 1980s. In 1990, Dolon had 40 Tupolev Tu-95 (Bear) aircraft, which were eliminated by 1994, ending the base's strategic bomber role.

Base (geometry)

In geometry, a base is a side of a polygon or a face of a polyhedron, particularly one oriented perpendicular to the direction in which height is measured, or on what is considered to be the "bottom" of the figure. This term is commonly applied to triangles, parallelograms, trapezoids, cylinders, cones, pyramids, parallelepipeds and frustums.

Role in area and volume calculation

Bases are commonly used (together with heights) to calculate the areas and volumes of figures. In speaking about these processes, the measure (length or area) of a figure's base is often referred to as its "base."

By this usage, the area of a parallelogram or the volume of a prism or cylinder can be calculated by multiplying its "base" by its height; likewise, the areas of triangles and the volumes of cones and pyramids are fractions of the products of their bases and heights. Some figures have two parallel bases (such as trapezoids and frustums), both of which are used to calculate the extent of the figures.

Dress shirt

A dress shirt, button shirt, button-front, button-front shirt, button-down, button-down shirt, or button-up shirt is a garment with a collar and a full-length opening at the front, which is fastened using buttons or shirt studs.

Dress shirts are normally made from woven cloth, and are often accompanied by a jacket, collar sleeve, and tie, for example with a suit or formalwear, but shirts are also worn more casually.

In British English, "dress shirt" means specifically the more formal evening garment worn with black- or white-tie. Some of these formal shirts have stiff fronts and detachable collars attached with collar studs.

Traditionally dress shirts were worn by men and boys, whereas women and girls often wore blouses or, sometimes, known as chemises. However, in the mid-1800s, they also became an item of women's clothing and are worn by both sexes today.

The term "button-down" refers to a type of shirt which has a collar fastened down by buttons, but is sometimes used in error to apply to all dress shirts.

Uniworld City

Uniworld City is the name given to a major township being developed in Rajarhat on the north-eastern fringes of Kolkata, India. The entire project is being developed by Unitech Group, a real estate company in India.

Arsenal Air 100

The Arsenal Air 100 is a French single seat competition sailplane produced in the 1940s. It sold in small numbers but set several records, still holding the world absolute solo glider endurance record of 56 h 15 m.

Design and development

The successful German Jacobs Weihe sailplane of 1938 strongly influenced several wartime and postwar designs such as the Italian CVV-6 Canguro and the British Slingsby Gull 4 and Sky. The Arsenal 100 was also Weihe based, with the intention of improving on that design. Work began before the war within a small design group named the Groupe de l'Air, led by Raymond Jarlaud.

The wings of the two aircraft are similar in design and construction. Both have spans of 18.0 m (59 ft 1 in) and are straight tapered with rounded wing tips, although the Air's taper ratio (wing root chord to tip chord) is higher, resulting a slightly greater aspect ratio. Some later Air 100s have squared-off tips terminated in streamlined "salmons". Both wings use the Göttingen 549 airfoil inboard of the tips, though the Air's roots have a thickened version. They are wooden single spar structures, plywood covered ahead of the spar and fabric covered behind. The Air 100 has slotted ailerons to improve roll rates and, inboard, has Schempp-Hirth parallel-rule airbrakes mounted immediately aft of the main spar; the Weihe's DFS style brakes had never been very effective, largely because their design placed them further aft on the wing where space did not allow them to open fully.
