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.
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.
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
An information cascade or informational cascade is a phenomenon described in behavioral economics and network theory in which a number of people make the same decision in a sequential fashion. It is similar to, but distinct from herd behavior. [1] [2] [3] An information cascade is generally accepted as a two-step process.
A cascade effect is an inevitable and sometimes unforeseen chain of events due to an act affecting a system. [1] If there is a possibility that the cascade effect will have a negative impact on the system, it is possible to analyze the effects with a consequence / impact analysis .
The jet exhibits a wide range of length scales, a prerequisite for the appearance of an energy cascade in the turbulence modelling. In continuum mechanics , an energy cascade involves the transfer of energy from large scales of motion to the small scales (called a direct energy cascade ) or a transfer of energy from the small scales to the ...
Cascade: Water descends a series of rock steps. [1] [2] Segmented: Distinctly separate flows of water form as it descends. [1] Tiered: Water drops in a series of distinct steps or falls. [1] Punchbowl: Water descends in a constricted form and then spreads out in a wider pool. [1]
