Numerical methods are useful for solving differential equations that model physical problems, for example, heat transfer, fluid dynamics, wave propagation, among others; especially when these cannot be solved by means of exact analysis techniques, since such problems present complex geometries, boundary or initial conditions, or involve non-linear differential equations. Currently, the number of problems that are modeled with partial differential equations are diverse and these must be addressed numerically, so that the results obtained are more in line with reality. In this work, a comparison of the classical numerical methods such as: the finite difference method (FDM) and the finite element method (FEM), with a modern technique of discretization called the mimetic method (MIM), or mimetic finite difference method or compatible method, is approac...

Nematodes of the Anisakidae family were studied in Sardinella aurita and Mugil curema caught in Venezuelan coastal waters and sold in Cumaná’s main market in Sucre state, Venezuela. Fifty fish of each species were analyzed, examined, dissected and their internal cavities, cephalic organs, abdominal trunk and caudal regions wereinspected. They were also debrided, and muscles dissected in search of nematodes in their third larval stage (L3) through simple visual examination. Detected nematode parasites were mechanically extracted from the organs and tissues for identification and classification at the genus level. The M. curema species was the only fish found to be infected with parasites. Distinct parasitic species were observed in 48/50 (96%) of the M. curema specimens analyzed. The prevalence of helminths in these specimens included nematodes of the Anisakidae family, Acanthocephala ...
