A generalization of the kinetic equation using the prabhakar-type operators
(Honam Mathematical Society, 2017)
Fractional kinetic equations are investigated in order to
describe the various phenomena governed by anomalous reaction in
dynamical systems with chaotic motion. Many authors have pro-
vided solutions of various families ...
Changes in the structure of melolonthidae (coleoptera: scarabaeoidea) assemblages along a temporal gradient in a natural reserve in Chaco, Argentina
(Wiley Online Library, 2017-05-26)
Melolonthidae beetles have been proposed as bioindicators because of their important role in the ecosystem and
