C Mathematical Functions
C mathematical operations are a group of functions in the standard library of the C programming language implementing basic mathematical functions. All functions use floating-point numbers in one manner or another. Different C standards provide different, albeit backwards-compatible, sets of functions. Most of these functions are also available in the C++ standard library, though in different headers (the C headers are included as well, but only as a deprecated compatibility feature). Overview of functions Most of the mathematical functions are defined in ( header in C++). The functions that operate on integers, such as abs, labs, div, and ldiv, are instead defined in the header ( header in C++). Any functions that operate on angles use radians as the unit of angle. Not all of these functions are available in the C89 version of the standard. For those that are, the functions accept only type double for the floating-point arguments, leading to expensive type conversions ...

Helga Labs
Helga Labs (born 22 May 1940) is an East German politician who served as the minister of public education of East Germany. Being a member of the ruling party Socialist Unity Party (SED), she held several political and public posts in East Germany. Early life and education Labs was born in Wenigtreben on 22 May 1940. Between 1955 and 1959 she studied at the institute for teacher training in Rochlitz and received a degree in teaching. Career Labs joined the Rochlitz branch of the Free German Youth organization in 1956 and served as its secretary between 1959 and 1960. In 1959 he became a member of the SED. In 1974 she was named as the head of the Ernst Thälmann Pioneer Organisation, a youth organization, replacing Egon Krenz in the post. Lab's tenure lasted until 1985, and she was replaced by Wilfried Poßner in the post. Labs was a member of the central committee of the SED from 1976 to 3 December 1989. She also served as chairman of the teaching and education union. In Nove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Low Altitude Bombing System
Toss bombing (sometimes known as loft bombing, and by the U.S. Air Force as the Low Altitude Bombing System, LABS) is a method of bombing where the attacking aircraft pulls upward when releasing its bomb load, giving the bomb additional time of flight by starting its ballistic path with an upward vector. The purpose of toss bombing is to compensate for the gravity drop of the bomb in flight, and allow an aircraft to bomb a target without flying directly over it. This is to avoid overflying a heavily defended target, or to distance the attacking aircraft from the blast effects of a nuclear (or conventional) bomb. Bomb tactics Pop-up In pop-up bombing, the pilot approaches from low altitude in level flight, and on cues from the computer pulls up at the last moment to release the bomb. Release usually occurs between 20° and 75° above the horizontal, causing the bomb to be tossed upward and forward, much like an underarm throw of a ball. Level toss Although "pop-up" bombing is ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sodium Dodecylbenzenesulfonate
Alkylbenzene sulfonates are a class of anionic surfactants, consisting of a hydrophilic sulfonate head-group and a hydrophobic alkylbenzene tail-group. Along with sodium laureth sulfate, they are one of the oldest and most widely used synthetic detergents and may be found in numerous personal-care products (soaps, shampoos, toothpaste etc.) and household-care products (laundry detergent, dishwashing liquid, spray cleaner etc.).Kurt Kosswig,"Surfactants" in Ullmann's Encyclopedia of Industrial Chemistry, Wiley-VCH, 2005, Weinheim. They were first introduced in the 1930s in the form of branched alkylbenzene sulfonates (BAS). However following environmental concerns these were replaced with linear alkylbenzene sulfonates (LAS) during the 1960s. Since then production has increased significantly from about one million tons in 1980, to around 3.5 million tons in 2016, making them most produced anionic surfactant after soaps. __TOC__ Branched alkylbenzene sulfonates Branched alkylb ...
