Problemas elípticos superlineares com ressonância
(Universidade Federal de São Carlos, 2015-08-14)
The aim of this work is to present results about the existence of non-trivial solutions for some classes of resonant and superlinear eliptic systems employing topological methods. More specifcally, we use a-priori bounds ...
Processos difusionais, cristalização e escoamento viscoso em dissilicato de bário vítreo
(Universidade Federal de São Carlos, 2014-04-24)
In this work, we analysed if the viscous flow successfully describes the transport of crystal nucleation and crystal growth structural units that occur at the liquid/crystal interface. In order to do this, we calculated ...
Estudos de melhorias no processo de hidrólise enzimática de biomassas para produção de etanol
(Universidade Federal de São Carlos, 2016-02-04)
In this work it was evaluated, firstly, the performance of four impellers configurations in the enzymatic hydrolysis of sugarcane bagasse. The configurations evaluated were: (1): Rushton turbine - Rushton turbine; (2): ...
Análise de critérios de seleção de materiais e processos para interiores de aeronaves executivas incorporando aspectos de sustentabilidade
(Universidade Federal de São Carlos, 2015-12-02)
Materials and processes used to manufacture executive aircraft interiors play an important role in aesthetic and competitive product differentiation, in a scenario where there is growing competition and pressures for more ...
Potencial de utilização de vinhaça como meio para o cultivo da microalga Chlorella vulgaris : aspectos toxicológicos e microbiológicos
(Universidade Federal de São Carlos, 2016-03-04)
Microalgae have been cultivated worldwide to obtain biomass for various applications.
Nonetheless the production costs of microalgae is still high due to factors such as
photobioreactors, water and nutrients to grow the ...
Beta-glicosidases das famílias GH 1 e GH 3 : caracterização estrutural, bioquímica e mecanismos estruturais de transglicosilação
(Universidade Federal de São Carlos, 2016-01-15)
The search for new sustainable alternative energy sources has followed the increasing
concerns with common welfare and fossil fuel shortage. In this context, Bioethanol is
a good option and lignocellulosic biomass is an ...
Problemas elípticos não lineares envolvendo equações do tipo Kirchhoff
(Universidade Federal de São Carlos, 2016-03-21)
In this work we study the existence of weak solutions for four nonlinear elliptic problems of Kirchhoff type. These problems have in common the presence of a function M : R+ [ f0g ! R+; known as Kirchhoff-type function. ...
Tunelamento ressonante de férmions massivos de Dirac em sistemas de simples e dupla barreiras em monocamada de grafeno
(Universidade Federal de São Carlos, 2015-04-29)
Nowadays, several efforts have been made by research groups around the physical
properties of the graphene in view of the possible technological applications of their
unique structural and electronic properties. The ...
Síntese de triazóis e análise estrutural de compostos organocalcogenetos triazólicos
(Universidade Federal de São Carlos, 2013-05-20)
In this study, we developed a synthetic route for obtaining new class of 1,2,3- triazole compounds. In the synthesis of these compounds were used flexible and modular methodologies, allowing to obtain a large number of ...
Suportes de simulação como objetos intermediários para incorporação da perspectiva da atividade na concepção de situações produtivas
(Universidade Federal de São Carlos, 2015-07-03)
Understanding the work in order to transform it is the concern of ergonomics. To expand
its capacity of effective intervention this discipline gets closer to the field of engineering,
especially the production engineering, ...
