"The fissility is the ability of some rocks to split along relatively smooth surfaces parallel to the bedding. This property observed mostly in fine-grained rocks is particularly expressed in outcrops, where rocks are su...

Although the problem of determining the minimum cost path through a graph arises naturally in a number of interesting applications, there has been no underlying theory to guide the development of efficient search procedu...

A general inductive approach for analysis of qualitative evaluation data is described. The purposes for using an inductive approach are to (a) condense raw textual data into a brief, summary format; (b) establish clear l...

Se ha estudiado la presencia de proteinasas en el alcaucil (Cynara scolymus L.) midiendo la actividad proteolítica y la capacidad coagulante de la leche de preparaciones crudas de diferentes partes de la inflorescencia ...

The aim of the present investigation is to improve the dissolution of poorly water soluble drug valsartan by preparing solid dispersions and also to evaluate the effect of different inert carriers on flow properties of s...

Systems as diverse as genetic networks or the World Wide Web are best described as networks with complex topology. A common property of many large networks is that the vertex connectivities follow a scale-free power-law ...

A perturbation theory is developed for treating a system of $n$ electrons in which the Hartree-Fock solution appears as the zero-order approximation. It is shown by this development that the first order correction for th...
