Ethane (US: / ˈɛθeɪn / ETH-ayn, UK: / ˈiː -/ EE-) is a naturally occurring organic chemical compound with chemical formula C. 2H. 6. At standard temperature and pressure, ethane is a colorless, odorless gas. Like many hydrocarbons, ethane is isolated on an industrial scale from natural gas and as a petrochemical by-product of petroleum ...
Thane (/ ˈ θ eɪ n /; Scottish Gaelic: taidhn) [1] was the title given to a local royal official in medieval eastern Scotland, equivalent in rank to the son of an earl, [2] who was at the head of an administrative and socio-economic unit known as a thanedom or thanage.
Maslow's hierarchy of human needs. This is an example of a hierarchy visualized with a triangle diagram. The hierarchical aspect represented here is that needs at lower levels of the pyramid are considered more basic and must be fulfilled before higher ones are met.

The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are possibly arranged in the real three-dimensional space. The chemical bonding within the molecule is also shown, either explicitly or implicitly.
In software engineering, a class diagram[1] in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system's classes, their attributes, operations (or methods), and the relationships among objects. The class diagram is the main building block of object-oriented modeling.
Structural integrity and failure is an aspect of engineering that deals with the ability of a structure to support a designed structural load (weight, force, etc.) without breaking and includes the study of past structural failures in order to prevent failures in future designs. Structural integrity is the ability of an item—either a ...
