I have trouble to understand what does it mean restrictions in Calculus: Integral with adjustable bounds sheet (https://www.desmos.com/calculator/u2qz73ufju) we can find this 0<=y<=f(x) {(a-x)(b-x)<0} I don't understand this restriction {(a-x)(b-x)<0} can you help me please ? best regards
Sacrificial anodes are pieces of metal attached to. the UST system that are more electrically active. than the steel UST system. Because these. anodes are more active, the corrosive current. will exit from them rather than the UST system. Thus, the UST system is protected while the. attached anode is âsacrificed.â.
Pentaerythritol tetranitrate. Pentaerythritol tetranitrate (PETN), also known as PENT, PENTA, TEN, corpent, penthrite (orârarely and primarily in Germanâas nitropenta), is the nitrate ester of pentaerythritol, and is structurally very similar to nitroglycerin. Penta refers to the five carbon atoms of the neopentane skeleton.
