This lists the character tables for the more common molecular point groups used in the study of molecular symmetry. These tables are based on the group-theoretical treatment of the symmetry operations present in common molecules, and are useful in molecular spectroscopy and quantum chemistry. Information regarding the use of the tables, as well ...
The irreducible complex characters of a finite group form a character table which encodes much useful information about the group G in a concise form. Each row is labelled by an irreducible character and the entries in the row are the values of that character on any representative of the respective conjugacy class of G (because characters are class functions).
Caterpillar D4H LGP (Low Ground Pressure) model, Eschborn, Germany. The Caterpillar D4 track-type tractor is a small bulldozer manufactured by Caterpillar Inc.. Caterpillar first introduced the RD4 in 1936, [1] as the diesel follow on to the successful CAT 30 gas model.
The D4H 1,000 mm (3 ft 3 + 3 ⁄ 8 in) and 9 locomotives D4Hr for standard gauge 1,435 mm (4 ft 8 + 1 ⁄ 2 in), also known as the TU7 - TU7A (ТУ7 - ТУ7А) diesel locomotive, [1] is a series of diesel locomotives currently used on the Vietnamese railway network.
Roblox occasionally hosts real-life and virtual events. They have in the past hosted events such as BloxCon, which was a convention for ordinary players on the platform. [45] Roblox operates annual Easter egg hunts [51] and also hosts an annual event called the "Bloxy Awards", an awards ceremony that also functions as a fundraiser. The 2020 ...
Rift Royale is a battle royale game developed by Easy.gg, the developers behind BedWars and Islands. The game was inspired by Fortnite Battle Royale, and was an attempt to create an "awesome competitive game" within the Roblox platforms limitations. In August 2022, the game was shut down following a mass wave of exploiters rendering the game ...
A more serious problem with this type of propeller is a "frozen-on" spline bushing, which makes propeller removal impossible. In such cases the propeller must be heated in order to deliberately destroy the rubber insert. Once the propeller is removed, the splined tube can be cut away with a grinder and a new spline bushing is then required.
The momentum theory or disk actuator theory – a theory describing a mathematical model of an ideal propeller – was developed by W.J.M. Rankine (1865), Alfred George Greenhill (1888) and Robert Edmund Froude (1889). The propeller is modelled as an infinitely thin disc, inducing a constant velocity along the axis of rotation.
