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 .
Adenosine may have opposite effects on bone metabolism, because while certain purinergic receptors stimulate adenylyl cyclase activity, others have the opposite effect. [ 58 ] [ 59 ] Under certain circumstances adenosine stimulates bone destruction and in other situations it promotes bone formation, depending on the purinergic receptor that is ...
In 1978, Kessler found that 42 percent of cataloged debris was the result of 19 events, primarily explosions of spent rocket stages (especially US Delta rockets). [12] He discovered this by first identifying those launches that were described as having a large number of objects associated with a payload, then researching the literature to ...
A representative example of a pericyclic cascade is the endiandric acid cascade reported by Nicolaou et al. in 1982 (Scheme 8). [ 4 ] [ 19 ] Herein the highly unsaturated system 39 was first hydrogenated to the conjugated tetraene species 40 , which upon heating underwent an 8π-conrotatory electrocyclic ring closure, yielding cyclic ...
An ecological cascade effect is a series of secondary extinctions that are triggered by the primary extinction of a key species in an ecosystem.Secondary extinctions are likely to occur when the threatened species are: dependent on a few specific food sources, mutualistic (dependent on the key species in some way), or forced to coexist with an invasive species that is introduced to the ecosystem.
Here are some Mandela effect examples that have confused me over the years — and many others too. Grab your friends and see which false memories you may share. 1.
The ischemic (ischaemic) cascade is a series of biochemical reactions that are initiated in the brain and other aerobic tissues after seconds to minutes of ischemia (inadequate blood supply). [1] This is typically secondary to stroke , injury, or cardiac arrest due to heart attack .
Popular belief: Kit-Kat Reality: Kit Kat Yes, it’s true: A hyphen doesn’t separate the “kit” from “kat.” The brand even addressed the Mandela effect in a tweet from 2016, saying “the ...
