Dynastic cycle (traditional Chinese: 朝代循環; simplified Chinese: 朝代循环; pinyin: Cháodài Xúnhuán) is an important political theory in Chinese history. According to this theory, each dynasty of China rises to a political, cultural, and economic peak and then, because of moral corruption, declines, loses the Mandate of Heaven ...
The nuclear fuel cycle, also called nuclear fuel chain, is the progression of nuclear fuel through a series of differing stages. It consists of steps in the front end , which are the preparation of the fuel, steps in the service period in which the fuel is used during reactor operation, and steps in the back end , which are necessary to safely ...
Zooming out from the dynastic cycle but maintaining focus on power dynamics, the following general periodization, based on the most powerful groups and the ways that power is used, has been proposed for Chinese history: [37]: 45 The aristocratic settlement state (to c. 550 BCE)
Although he did not live to see the Zhou conquest of Shang, his legitimacy passed to his heirs. [20] Early on in the dynasty, there was some debate as to whether Heaven's mandate had fallen to the senior sons of King Wen's line, or to the house of Zhou as a group, as exemplified by an exchange surviving in the classic Book of Documents.

A Brayton cycle that is driven in reverse uses work to move heat. This makes it a form of gas refrigeration cycle. When air is the working fluid, it is known as the Bell Coleman cycle. [20] It is also used in the LNG industry for subcooling LNG using power from a gas turbine to drive the compressor. [dubious – discuss] [citation needed]
The laws describing the behaviour of gases under fixed pressure, volume, amount of gas, and absolute temperature conditions are called gas laws.The basic gas laws were discovered by the end of the 18th century when scientists found out that relationships between pressure, volume and temperature of a sample of gas could be obtained which would hold to approximation for all gases.
Teenagers are inhaling canisters of nitrous oxide sold under the brand name Galaxy Gas The brightly colored canisters are used to make airy whipped creams, but can cause “life-threatening health ...
The history of thermodynamics is a fundamental strand in the history of physics, the history of chemistry, and the history of science in general. Due to the relevance of thermodynamics in much of science and technology, its history is finely woven with the developments of classical mechanics, quantum mechanics, magnetism, and chemical kinetics, to more distant applied fields such as ...
