1. IMPLEMENTAÇÃO DA TÉCNICA DE FOTOACÚSTICA DE CÉLULA ABERTA PARA OBTENÇÃO DA DIFUSIVIDADE TÉRMICA DE METAIS
The photo-acoustic technique has become a standard photo-thermal method for carrying out diverse studies on solids materials. Photo-thermal phenomena in solids results from a combination of thermal expansion, thermal diffusion, and thermo-elastic bending effects and can be obtained by c k . r a = where k is the thermal conductivity, r is the density, and c i

2. Immobilization of proteins onto polysaccharide surfaces / Imobilização de proteínas sobre superfícies de polissacarídeos
This thesis presents the study on thin film formation and characterization of xyloglucans extracted from two different sources, Hymenaea courbaril (HXG) and Tamarindus indica (TXG) onto Si/SiO2 wafers or amino-terminated wafers, as well as the application of these films as substrates for the immobilization of the lectin concanavalin A (Con A) by means of ell

3. O direito de superfície no ordenamento jurídico brasileiro
O direito de superfície é figura de direito real imobiliária, de natureza bem complexa, com previsão no Estatuto da Cidade e no Código Civil, admitindo ampla transmissibilidade. O instituto estudado possui origens no direito romano, tendo o modelo pátrio forte influência do direito luso, até mesmo pelas razões históricas que no passado nos uniram.

4. Treatment corona on surfaces textiles / Tratamento corona sobre superficies texteis
Amongst the techniques of modification of surfaces applied in the industry to improve adhesion, the treatment for discharge corona widely is used. During the treatment for discharge corona, active species are generated, which can consequently react with the surface of polymer causing chain in addition and formation of radicals, thus creating polar groups in

5. Minimal sufaces foliated by circunferences / Superficies minimas folheadas por circunferencias
Minimal surfaces are known to be the ones with mean curvature zero. Classical exampIes are the catenoid, helicoid and the Scherk surface. Historically, they were associated with the property of minimizing area. However, they can even maximize it localIy for cases of normal variation which include the boundary. For fixed boundary, we shalI analyse when they r

6. A metric property of umbilic points
No espaço das formas cúbicas de superfícies, consideradas como um G-espaço e munido de uma métrica invariante, é avaliado o quociente dos volume das formas cúbicas correspondentes aos umbílicos de índice negativo pelo volume daquele correspondente aos umbíicos de índice positivo. Esta avaliação é expressa em termos da assimetria da métrica, de

7. LIQUID DISPLACEMENT OF IMISCIBLE FLUIDS IN TUBES: CAPILLARITY, INERCIA, VISCOSITY RATIO AND RHEOLOGICAL PROPERTY EFFECTS / DESLOCAMENTO DE FLUIDOS IMISCÍVEIS EM TUBOS: EFEITO DE CAPILARIDADE, INÉRCIA, RAZ ÃO DE VISCOSIDADES E PROPRIEDADES REOL OGICAS
There are many important processes in industry that use liquid displacement of imiscible fluids in tubes. Some practical applications include enhanced oil recovery, ce- mentation of drilling wells and coating of internal surfaces of the tubes. For a good understanding of these problems, it is extremely important to study the effect of cap-illarity,inertia an
