A ski binding is a device that connects a ski boot to the ski. Before the 1933 invention of ski lifts, skiers went uphill and down and cross-country on the same gear. As ski lifts became more prevalent, skis—and their bindings—became increasingly specialized, differentiated between alpine (downhill) and Nordic (cross-country, Telemark, and ...
Marker International is a German manufacturing company of equipment for winter sports established in 1952 and headquartered in Straubing, Lower Bavaria. Founded by Hannes Marker, the company is known for pioneering releasable binding technology. Marker's first model, the Duplex was followed in 1953 by the Simplex toe binding which was a huge ...
A binding interaction between a small molecule ligand and an enzyme protein may result in activation or inhibition of the enzyme. If the protein is a receptor, ligand binding may result in agonism or antagonism. Docking is most commonly used in the field of drug design — most drugs are small organic molecules, and docking may be applied to:
Spademan was a type of ski binding, one of a number of "plate bindings" that were popular in alpine skiing during the 1970s. It used a bronze plate screwed into the bottom of the boot as its connection point, held to the ski by a clamp-like mechanism that grasped the side of the plate. Unlike conventional bindings, the Spademan could release in ...
de Bruijn index. In mathematical logic, the de Bruijn index is a tool invented by the Dutch mathematician Nicolaas Govert de Bruijn for representing terms of lambda calculus without naming the bound variables. [1] Terms written using these indices are invariant with respect to α-conversion, so the check for α-equivalence is the same as that ...
Stability constants of complexes. In coordination chemistry, a stability constant (also called formation constant or binding constant) is an equilibrium constant for the formation of a complex in solution. It is a measure of the strength of the interaction between the reagents that come together to form the complex.
Adding 4 hours to 9 o'clock gives 1 o'clock, since 13 is congruent to 1 modulo 12. In mathematics, modular arithmetic is a system of arithmetic for integers, where numbers "wrap around" when reaching a certain value, called the modulus. The modern approach to modular arithmetic was developed by Carl Friedrich Gauss in his book Disquisitiones ...
Loops. A shoe using hook-and-loop closures. Hook-and-loop fasteners, also known as hook-and-pile fasteners or touch fasteners, are devices that allow two surfaces to be repeatedly fastened and unfastened, commonly used in clothing and other applications. They are often referred to by the genericized trademark velcro, which was the original name ...
