25. ESPECIALIZATION OF AGRICULTURAL IN REGION COREDE FRONTEIRA OESTE DO RIO GRANDE DO SUL: An geographical analysis of the production of rice, soybean, corn and wheat / ESPECIALIZAÇÃO DA AGRICULTURA NA REGIÃO COREDE FRONTEIRA OESTE DO RIO GRANDE DO SUL: Uma análise geográfica da produção de arroz, soja, milho e trigo.
This study aims to analyze in the geographical category rural space the agricultural production of the territory belonging to the region COREDE Fronteira Oeste do RS, through the contemporaneous acceleration, due to the Tecnic-Scientific-Informacional period following the globalization process f the economics. This region COREDE was analyzed from the intensi

26. Variedades com curvatura prescrita : resultados de existÃncia, unicidade, rigidez e bifurcaÃÃo / Manifolds with prescribe curvature: results of existence uniqueness, rigidity and bifurcation
We present several results of existence, uniqueness, rigidity and bifurcation for the problem of prescribing various geometric structures on Riemannian manifolds, among which include: i) deformation and rigidity for 2k-Einstein structures on manifolds with constant (2k − 2)-sectional curvature; ii) conformal deformation of metrics in the context of the

27. A contribuição da União Europeia à governança da mudança climática global: explicando as condições para a actorness da UE
As a regional organization, the European Union's role in global climate governance faces constraints that do not apply to other members of the United Nations Framework Convention on Climate Change (UNFCCC) and Kyoto Protocol. Addressing that uniqueness, this article provides a theoretical and empirical analysis of how the elements of actorness (recognition,

28. Numerical analysis of the nonlinear subgrid scale method
This paper presents the numerical analysis of the Nonlinear Subgrid Scale (NSGS) model for approximating singularly perturbed transport models. The NSGS is a free parameter subgrid stabilizing method that introduces an extra stability only onto the subgrid scales. Thisnew feature comes from the local control yielded by decomposing the velocity field into the

29. Justiça em Paul Ricoeur: uma hermenêutica do homem justo
This work deals with the in Paul Ricoeur developed Justice philosophy theory based in the hermeneuthics of judge decisions. The understanding of such concept leads to the investigation of mans ability to judge (decide) on the basis of ethical values and trustful behaviour as well. The Thesis main purpose is the identification of the three levels of elements

30. Sobre rigidez de hipersuperfÃcies completas / On rigidity of complete hypersurfaces
The purpose of this thesis is to obtain characterization theorems of complete spacelike hypersurfaces isometrically immersed in a semi-Riemannian ambient space under some restrictions on the Gauss mapping or about the r-mean curvatures of these objects. We start our work by providing necessary conditions to ensure the umbilicity of immersed hypersurfaces in

31. Controlabilidade Finito-Aproximada e Nula para a Equação do Calor Semilinear / Controlabilidade Finito-Aproximada e Nula para a Equação do Calor Semilinear
Consideremos a equação do calor semilinear envolvendo termos do gradiente em um domínio limitado do Rn. Assumimos que a não-linearidade é globalmente Lipschtz. Usando o método do ponto fixo, provamos que o sistema é finito-aproximadamente controlável e nulamente controlável, quando o controle age em um subconjunto não vazio do domínio.

32. Os processos de (re)estruturação do tecido urbano de Vila Rica: a influência da Igreja Católica
Since the beginning of formation of Ouro Preto (formerly Vila Rica), the Church stood out in the landscape of the camps wich were created there. Simultaneously, the streets (and churchyards / plazas) were then setting, often from the surroundings of these temples. In the first decade of the century, two parishes (known as Nossa Senhora doPilar de Ouro Preto

33. Some characterization, uniqueness and existence results for euclidean graphs of constant mean curvature with planar boundary
We establish the existence and uniqueness of solutions to the Dirichlet problem for the cmc surface equation, including the minimal one, for zero boundary data, in certain domains of the plane. We obtain results that characterize the sphere and cmc graphs among compact embedded cmc surfaces with planar boundary satisfying certain geometric conditions. We als

34. Closed balls for interpolating quasi-polynomials
The classic interpolation problem asks for polynomials to fit a set of given data. In this paper, quasi-polynomials are considered as interpolating functions passing through a set of spatial points. Existence and uniqueness is obtained by means of generalized Vandermonde determinants. By means of several estimates related to these determinants, we are also a

35. On a nonstationary nonlinear coupled system
In this paper, a strongly nonlinear coupled elliptic-parabolic system modelling a class of engineering problems with heat effect is studied. Existence of a weak solution is first established by Schauder fixed point theorem, where the coupled functions σ(s), k(s) are assumed to be bounded. The uniqueness of the solution is obtained by applying Meyers' theore

36. Genetic diversity and population structure of Brazilian native bovine breeds.
Conservation and improvement strategies should be based on the association between genetic and phenotypic characteristics. The objective of this work was to characterize five native Brazilian cattle breeds (Caracu, Crioulo Lageano, Curraleiro, National Polled and Pantaneiro) and two commercial breeds (Holstein and Nellore) using RAPD technique to estimate ge
