Desenvolvimento e caracterização de blendas Poli(tereftalato de etileno) - PET/ Poli(naftalato de etileno)- PEN
(Universidade Federal de São Carlos, 2000-03-03)
The scientific and technological development of food packaging polymers has increased considerably over the last years, especially in relationship to packaging for beverages such as carbonated soft drinks and beer. As for ...
Processos estocásticos de reação e difusão na rede e cadeias quânticas
(Universidade Federal de São Carlos, 2000-06-02)
In this work we investigate some reaction-difusion stochastic processes on the lattice. In particular, we determine the universality classes of critical behavior of a nonequilibrium surface growth process and of the basic ...
Estudo da influência dos óxidos de Mn, Co e Cr nas propriedades varistoras do sistema SnO2Nb2O5.
(Universidade Federal de São Carlos, 2000-12-01)
Aiming at obtaining SnO2 based varistor systems with a high degree of non linearity, new varistor compositions were studied, by means of doping the known SnO2.Nb2O5.CoO system with Cr2O3 and MnO2, as well as changing the ...
Estudo de pós cerâmicos de PbTiO3 utilizando-se o método dos precursores poliméricos.
(Universidade Federal de São Carlos, 2000-11-30)
THE STUDY OF PbTiO3 (PT) CERAMIC POWDERS USING THE POLYMERIC PRECURSOR METHOD was started by the preparation of a precursor solution of metallic cations. Citric acid was used as quelation agent and ethylene glycol as ...
Secagem de gel ágar.
(Universidade Federal de São Carlos, 2000-02-29)
Agar-agar is a hydrofilic colloid extracted from seaweed, mainly from algae Gelidium. It s used as culture medium in microbiology and as emulsificant, stabilizer and gelling in foods. Drying is an important operation in ...
Programação da produção : uma abordagem por redes neurais artificiais.
(Universidade Federal de São Carlos, 2000-02-27)
Production scheduling finds in the most detailed and complex level of
production planning and control systems. Due to its nature combinatorial,
several methods have been proposed to solve it. Among them there are the
techniques ...
Controle da volatilização de inibidores voláteis de corrosão através de suporte de alumina
(Universidade Federal de São Carlos, 2000-10-20)
During the process of the fabrication, storage and transport of equipments, the control of metallic corrosion can make though vapor phase corrosion inhibitors (VCI). These inhibitors are, generally, organic salts deriving ...
Indicadores de sustentabilidade urbana: as perspectivas e as limitações da operacionalização de um referencial sustentável
(Universidade Federal de São Carlos, 2000-04-05)
The complexity of the problems deriving from urban environments has required a deeper and more integrated understanding of the reality of these environments as an
essential step toward solutions. The main purpose of this ...
