In chemical engineering, a cascade is a plant consisting of several similar stages with each processing the output from the previous stage. Cascades are most commonly used in isotope separation , distillation , flotation and other separation or purification processes.
Cascade reactions are often key steps in the efficient total synthesis of complex natural products. The key step in Heathcock's synthesis of dihydroprotodaphniphylline features a highly efficient cascade involving two aldehyde/amine condensations, a Prins-like cyclization, and a 1,5-hydride transfer to afford a pentacyclic structure from an acyclic starting material.
For some, an initialism [1] or alphabetism, connotes this general meaning, and an acronym is a subset with a narrower definition: an acronym is pronounced as a word rather than as a sequence of letters.
Cascade (chemical engineering), a series of chemical processes Cascade amplifier, any two-port network constructed from a series of amplifiers; Cascade connection, a type of electrical network connection
A biochemical cascade, also known as a signaling cascade or signaling pathway, is a series of chemical reactions that occur within a biological cell when initiated by a stimulus.
TD – total depth (depth of the end of the well; also a verb, to reach the final depth, used as an acronym in this case [citation needed]) TDD – total depth (driller) TDC - Top Dead Center; TDC – total drilling cost; TDL – total depth (logger) TDM – touch-down monitoring; TDP – touch-down point; TDS – top drive system; TDS ...

Simple explanation of the mechanisms of apoptosis triggered by internal signals (bcl-2), along the caspase-9, caspase-3 and caspase-7 pathway; and by external signals ...
An availability cascade is a self-reinforcing cycle that explains the development of certain kinds of collective beliefs. A novel idea or insight, usually one that seems to explain a complex process in a simple or straightforward manner, gains rapid currency in the popular discourse by its very simplicity and by its apparent insightfulness.
