Separable EST expansions of potentials which vanish outside a certain radius are studied by using as a basis complete sets of eigenfunctions obtained by applying appropriate boundary conditions. The method is applied to ...

The thermal denaturation of DNA, i.e. the separation of the two strands is a phenomenon caused by the amplitude of the vibrations of the bases, therefore it is necessary to know how such separation is generated in order ...

Both the variational approach and the method of separable expansion have proved to be very useful for the solution of scattering equations. Connections are established between these two approaches. It is shown that an ...

A method is presented to synthesize process flowsheets for separations of mixtures by fractional crystallization. Using equilibrium data for a candidate set of potential operating point temperatures, a network flow model ...

Fracture toughness of ductile polymers can be measured by the incremental crack growth resistance curve, where J-Integral value is plotted as a function of crack extension. The determination of the resistance curve, J-R, ...

The prevalence of Yersinia enterocolitica in meat products was assessed by four methods: cold enrichment in trypticase soy broth (A), enrichment in modified Rappaport broth at 25 C (B), concentration by immunomagnetic ...

Composites of montmorillonite (MMT) and polyaniline (PANI) were synthetized through a facile and inexpensive method. Two samples with different MMT:PANI ratios were studied and deeply characterized by XRD, TG, zeta potential, ...
