13. Solving tangency problems by inversions and engineering applications. / Resolução de problemas de tangências por inversões e aplicações à engenharia.
A new method to solve the tenth case of Appolonius problem is presented in this study. This method is based on the geometric transformation called inversion and the concept of coaxal circumferences. Besides allowing the resolution of all configurations of the problem, it can also be used to solve other problems. We indicate the importance of the subject abou

14. Cálculo da elasticidade de cristais líquidos nemáticos através de métodos da geometria diferencial
Found on Frank free energy relation, the bulk elastic constants of the nematic liquid crystals are computed in this work through an approach based on the affine connection method. This consists in the deformation of the isotropic fluid sferical molecules until they acquire an elipsoidal shape, likely the estimated nematic molecules form. Herewith the method

17. Aplicação da descrição cinemática co-rotacional na análise não-linear geométrica de estruturas discretizadas por elementos finitos de treliças, vigas e cascas / The application of the co-rotational kinematic description to the geometrically non-linear analysis of structures modeled by truss, beam and shell finite elements
The co-rotational formulation was used as the kinematic description to evaluate the geometrically non-linear behavior of different types of structures on a static analysis. Along the current research, it was aimed to demonstrate the basic concepts of the co-rotational approach that is based on the separation of the total motion into rigid body and deformatio

19. Produção de forragem e transformações do nitrogênio do fertilizante em pastagem irrigada de capim Tanzânia. / Herbage production and transformations of the fertilizer nitrogen in irrigated tanzania grass.
Whilst grazing management is a key component in pastoral systems little effort has been made to determine the adequate grazing intensity for tropical pastures, especially under irrigated conditions. The economical attractiveness of irrigated pasture systems depends on high pasture productivity, meaning that fertilizer nitrogen (N) must be used. However, to m

21. Valores de referência de acetona urinária em uma população do sul de Minas Gerais / Reference values for urinary acetone in a population of south of Minas Gerais state
The determination of reference values of some xenobiotics is important for the biomonitoring, to compare the concentration in the exposed and the general population. The acetone is a very popular solvent, that is used in a large number of industries and laboratories. Isopropanol is used in industries, laboratories and cosmetic products. In the human body, th

22. Fundamentos geometricos e algebricos da calibração e reconstrução tridimensional : aplicação na analise cinematica de movimentos humanos / Geometric and algebraic basis for calibra tion and threedimensional re construcion. application in the kinematic analysis of human movements
To get information such as position, orientation and size of the object of interest by measuring its image are the basis of the kinematic analysis of the human movement. Video cameras are frequently used for this purpose. The aim of this work is to study Geometric and AIgebraic concepts of the procedures used to calibrate the video cameras and of the reconst

23. Modelo de linha de transmissão polifasica utilizando quase-modos
In the present work new models to represent transmission tines including the frequency dependency of longitudinal parameters are presented. The parameters are represented in the mode domain through a cascade of 1tcircuits. The model characteristic is to take advantage of the tine geometric properties and use real phase-mode transformation matrices; the funct
