1. Análise da influência da condutividade hidráulica saturada dos solos nos escorregamentos rasos na bacia do rio Guaxinduba (SP) / Analysis of the influence of saturated hydraulic conductivity from soils in the shallow landslides in the Basin of the River Guaxinduba (SP)
The prediction of landslides-prone areas has as fundamental step researching controlling factors and failure mechanisms. Some of these properties, such as the physical and hydrological soil properties are crucial to the instability of slopes subject to intense rainfall events. One of these properties is the saturated hydraulic conductivity, whose behavior ca

2. DinÃmica de VÃrtices pontuais na esfera S2 e no espaÃo hiperbÃlico
We present the movement equations of n punctual vortices over the following Riemann surfaces: the sphere S2 and the hyperbolic space H2. We also state the Hamiltonian formulation of the vortices motion over these surfaces. For this purpose, we primarily present the stereographic projection over S2 and over H2. Then, we construct the Laplace-Beltrami operator

3. Do teorema de Cauchy ao metodo de Cagniard
This work is about complex variables, in particular about Cauchy s integral theorem and its consequences and applications. We have, as consequences of Cauchy s integral theorem, Cauchy s theorem and the residue theorem, a keynote to the development of this work. As for the applications, our main objective was to study the integral transforms as a method to s

4. Potencials and electric fields inside and outside resistive conductors carrying steady currents / Potenciais e campos eletricos dentro e fora de condutores resistivos com correntes constantes
In Chapter 1 we present an introduction about the electric field inside and outside resistive conductors carrying steady currents. We also discuss the distribution of surface charges that maintains the current fiow and its relation with these electric fields. We present some experiments related with these electric fields outside conductors with steady curren

5. Solução de problemas poroelasticos atraves do metodo dos elementos de contorno
The Biot s theory af poroelasticity is revisited making it more easily applicable to practical problems. The parameters used by Biot are redefined as functions of other ones with an easier and simpler physical interpretation. This helps their determination and the understanding of poroelastic phenomena. The equations that govern the theory of quasi-static li

6. Analogue solution for electrical capacity of membrane covered square cylinders in square array at high concentration.
Analytical solutions of Laplace equations have given the electrical characteristics of membranes and interiors of spherical, ellipsoidal, and cylindrical cells in suspensions and tissues from impedance measurements, but the underlying assumptions may be invalid above 50% volume concentrations. However, resistance measurements on several nonconducting, close-

7. Kinetics of Heterogeneous Chemical Reactions: A Theoretical Model for the Accumulation of Pesticides in Soil
A theoretical model for the accumulation of pesticides in soil has been proposed and discussed from the viewpoint of heterogeneous reaction kinetics with a basic aim to understand the complex nature of soil processes relating to the environmental pollution. In the bulk of soil, the pesticide disappears by diffusion and a chemical reaction; the rate processes
