A process flow diagram ( PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations. Another commonly used term for a PFD is ...
Electron mobility. In solid-state physics, the electron mobility characterises how quickly an electron can move through a metal or semiconductor when pushed or pulled by an electric field. There is an analogous quantity for holes, called hole mobility. The term carrier mobility refers in general to both electron and hole mobility.
Process engineering is the understanding and application of the fundamental principles and laws of nature that allow humans to transform raw material and energy into products that are useful to society, at an industrial level. [ 1] By taking advantage of the driving forces of nature such as pressure, temperature and concentration gradients, as ...
Pitirim Sorokin defines horizontal mobility as a change in religious, regional, political, or other horizontal shifts without any change in vertical position. [ 2] According to Andrew W. Lind, horizontal mobility occurs when a person changes their profession, but their social status remains unchanged. Eg. if a doctor switches from a job in ...
A flux pen used for electronics rework. Multicore solder containing flux. Wire freshly coated with solder, held above molten rosin flux. In metallurgy, a flux is a chemical reducing agent, flowing agent, or purifying agent. Fluxes may have more than one function at a time.
The study's authors suggest they may have used boats. Scientists say they’ve cracked a secret of the 6-ton rock at the center of Stonehenge — a discovery that only deepens the site’s mystery ...
Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
Mobilities. Mobilities is a contemporary paradigm in the social sciences that explores the movement of people ( human migration, individual mobility, travel, transport ), ideas (see e.g. meme) and things (transport), as well as the broader social implications of those movements. Mobility can also be thought as the movement of people through ...
