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 ...
Contribuições ao estudo da secagem em um leito pneumático vertical
(Universidade Federal de São Carlos, 2004-03-30)
Pneumatic dryers are widely applied in industry, mainly because the transport of particulate material can be performed simultaneously with heating and drying operations. However, the design of such equipment is still based ...
Estudo do comportamento da deposição das partículas de diferentes meios filtrantes
(Universidade Federal de São Carlos, 2008-03-17)
Many studies related to bag filters have focused on minimizing the amount of energy used in the process. Seeking longer filtration cycles, lower frequency of cleaning cycles and a longer filter life, such studies search ...
Influência do alimentador de sólidos na fluidodinâmica do transporte pneumático
(Universidade Federal de São Carlos, 2007-03-13)
Pneumatic transport is an operation where powdery and granular materials are conveyed through a pipeline suspended in a gas flow. It is usually found in several industries segments and it is used as a carrier, such as, in ...
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 ...
Quantificação de apoptose e necrose mediante corantes fluorescentes e análise de imagens, no cultivo de células de inseto: o caso da Drosophila melanogaster S2
(Universidade Federal de São Carlos, 2007-03-28)
In animal cell cultures there are two kinds of cell death: apoptosis
(programmed cell death) and necrosis (cell death due to external sources). The inovative
method of cell death identification that have attracted interest ...
Imobilização da enzima β-galactosidase de Kluyveromyces fragilis em agarose e quitosana utilizando diferentes protocolos de ativação
(Universidade Federal de São Carlos, 2009-02-27)
The objective of this work was stabilize and immobilize β-galactosidase from activated agarose and chitosan supports. Initially, it was evaluated the buffer type, ionic strength and bivalent ions Mn2+ and Mg2+ on the ...
Reforma a vapor do etanol sobre catalisadores de Ni e Co suportados
(Universidade Federal de São Carlos, 2004-08-17)
The Ni and Co catalysts supported on Al2O3 and 12%La-Al2O3 and the carrier 12%La-Al2O3 were prepared by impregnation of the support with an aqueous solution of corresponding nitrates metals. The catalysts were characterized ...
Projeto, construção, testes e operação de um extrator de óleos vegetais
(Universidade Federal de São Carlos, 2006-03-02)
Brazil is a rich country in biodiversity holding a great variety of plants,
being one of the main constituents - oil that has been searched by the industries,
especially, pharmaceutic, food and cosmetic. Among the plants ...
