in this work facile sol-gel (pechni) method has been successfully established to synthesize zn4b6o13 nanocrystals which have cubic crystals with lattice parameter: a =7.48 a. the structure and morphology of the obtained material were studied by x-ray diffraction (xrd), infrared spectra (ir), scanning electron microscopy (sem) and photoluminescence analysis. the experimental results show a band ...

A numerical scheme based on the finite volume approach is developed to solve a binary breakage population balance equation (PBE) nonuniform meshes. The key feature of new that it free common requirement redistributing particle mass neighboring pivots, its formulation simpler compared other methods such as cell average and fixed pivot techniques. produces accurate results for distribution first ...

Saccharomyces cerevisiae (baker’s yeast) can exhibit sustained oscillations during the operation in a continuous bioreactor that adversely affects its stability and productivity. Because of heterogeneous nature of cell populations, the cell population balance equation (PBE) can be used to capture the dynamic behavior of such cultures. In this work, an unstructured-segregated model is used f...

Data cleaning and manipulation is an expensive and tedious process that consumes valuable time and resources. If an end-user needs to manipulate a large amount of data, he has three primary options: record a macro, write a transformation program, or perform manual manipulations on the data. Recording a macro with a fixed series of actions can be simple, but does not generalize well and is not s...

In this study, by using the first-principles calculations based on density functional theory (DFT), electronic aspects of GeP2S monolayer under effect buckling variation parameter (μ = 0, 2, 4, 6) are theoretically investigated PBE-GGA approximation method, and obtained results have been compared with previous similar structures. The imaginary part dielectric function absorption spectra is pres...

O paradigma da Prática Baseada em Evidências (PBE) surgiu na década de 1990 medicina e, gradualmente, passou a ser incorporado por outras áreas saúde, incluindo psicologia. A PBE é definida como o processo individualizado tomada decisão clínica que ocorre meio integração melhor evidência disponível com perícia no contexto das características individuais do paciente. concepção uma psicoterapia p...
