This paper deals with a systematic study of the convolution operator Kf = f (*) k defined on weighted pseudo almost periodic functions space PAP(X, rho) and with k is an element of L-1(R). Upon making several different ...

We study here the existence of solutions to the nonlinear Dirichlet problem (P): (phi(u'))' + f(t, u) = q(t), a.e. for t is an element of [a, b], u(a)=u(b)=0, where phi is an increasing odd homeomorphism of R, f:[a, b]XR ...

An experimental mixture plan was used in order to assess the composition effects on the catalytic activity of a ternary Cu–ZnO–Al2O3 catalyst for the water gas shift reaction (WGSR) in a constrained region of the mixture ...

Península Valdés (PV) in Argentina is an important calving ground for the southern right whale Eubalaena australis. However, a high mortality of calves has been observed in the last years, which could be associated with ...

Pseudo-nitzschia is a genus of marine diatoms, widely distributed from tropical to polar regions. Over 35 species have been described, some of which produce domoic acid (DA). This neurotoxin is responsible for the intoxication ...

In this work, a reaction protocol was developed for a new class of pseudo-peptides through multicomponent reactions (MCR) of the Ugi’s four component reaction (U-4CR) type, starting from chalcogenonucleosides. The synthetic ...
