been prepared by three different methods: precipitation, citrate ...
Sólidos micro-mesoestruturados tipo zeólita ZSM-5/peneira molecular MCM-41 - síntese e estudo de propriedades.
(Universidade Federal de São Carlos, 2006-08-16)
In the transformation of bulky molecules, the necessity of catalysts that allow the diffusion to and from the active sites located in the interior of the porous system has become of higher interest. The restriction for the ...
Avaliação de fontes de carbono e condições de indução na expressão de canacistatina em Escherichia coli BL21 (DE3)
(Universidade Federal de São Carlos, 2006-03-30)
Canecystatin (CC) is a competitive and reversible protease inhibitor which blocks the proteolytic enzymes activities of insets, fungus e nematodes, prejudicing thus the growth, development and reproduction from these ...
Comportamento da filtração de gases em meios filtrantes de celulose.
(Universidade Federal de São Carlos, 2006-09-15)
The present work aims to evaluate, through filtration process and cake detachment, the
behavior of two cellulose fiber filtering media with different air permeability values. The
powder material used was phosphatic ...
Estudo de condições operacionais na produção de penicilina G acilase por diferentes microrganismos
(Universidade Federal de São Carlos, 2006-12-20)
Penicillin G acylase (PGA) is an enzyme of major impact in human health for
catalyzing the deacilation of the penicillin G, to yield 6-aminopenicillanic acid (6-
APA), key intermediate in the semi-synthetic antibiotics ...
Filtração de gases: estudo da deposição de diferentes tortas de filtração em diferentes meios filtrantes
(Universidade Federal de São Carlos, 2006-06-19)
The particle retention inside a filter medium, after cleaning, significantly improves the
initial pressure drop during the subsequent cycle, that is, the residual pressure drop.
However, the way as these particles ...
Estudo da fluidodinâmica em leito fixo utilizando-se métodos numéricos de solução: escoamento monofásico de ar
(Universidade Federal de São Carlos, 2006-03-09)
Studies accomplished in the structure of tubular fixed beds proved that the porosity in these systems presents an oscillatory behavior along the radial direction. The non-uniformity of the porosity generates a behavior of ...
Análise do comportamento da fluidodinâmica do leito de jorro com misturas de tamanho de partículas
(Universidade Federal de São Carlos, 2006-08-01)
This research study presents an investigation to quantify the stability
of spouting regimes (by pressure fluctuations) and particle segregation level in
conical spouted beds operated with a variety of particle combinations ...
