The DO sag equation using a second-order BOD model fills a gap in the literature, as a number of investigators had explored describing BOD decay as a second-order reaction but the corresponding DO sag equation was not available to predict the impact of such wastes on a river....

A nuclear reaction can be defined as the reaction in which heavy nuclei split into small nuclei. The nuclear reaction shows various types of decay. They are used in many fields like cancer treatment, tracing devices, agriculture, industry, nuclear reactors, and many types of security dev...

TheArrhenius equationis a simple, but remarkably accurate, formula for the temperature dependence of thereaction rate constant, and therefore, rate of a chemical reaction.[1]The equation was first proposed by the Dutch chemistJ. H. van 't Hoffin 1884; five years later in 1889, the Swedish ...
Reaction-diffusion equationsInitial dataSlow decayAccelerating frontsThe Fisher-KPP equation is a model for population dynamics that has generated a huge amount of interest since its introduction in 1937. The speed with which a population spreads has been computed quite precisely when the initial data...

7.19 are identical to the net reaction rates. As the pathway is still simple enough for attempting on full solution, we shall show how this problem can be solved without further approximation. Mole balances of all the species in the batch reactor lead to (7.105)dCSdt=−k1CSCE−CSE/KS ...
This works studies a quasilinear, reaction-diffusion type parabolic free boundary problem modelling population dynamics. Hlder norm á priori estimates are established for the free boundary and the solution. Uniqueness of the solution is shown and qualitative properties of the solution are investigated....
