1. Avaliação de impacto do programa nacional de crédito fundiário na região sul do Brasil / Impact evaluation of Programa Nacional de Crédito Fundiário in the south region of Brazil
Since it was a colony, Brazil has presented a very concentrated land property structure. From the 30s on, laws and politics have been developed in order to promote an agrarian reform. In the present days, two alternative models of agrarian reform are being applied in Brazil expropriation of non-productive land (traditional model) and acquisition of land by m

2. EXPERIMENTAL STUDY OF AXIAL FLOW THROUGH AND ANNULAR REGION WITH INNER CYLINDER ROTATION / ESTUDO EXPERIMENTAL DO ESCOAMENTO AXIAL ATRAVÉS DE REGIÃO ANULAR COM ROTAÇÃO DO CILINDRO INTERNO
The flow between concentric cylinders with an inner rotating cylinder with an imposed pressure-driven axial flow was studied experimentally. The radius ratio was (n) = 0, 64 and the aspect ration was (r) = 265. Friction factor and velocity fields were studied for four rotations of the inner cylinder and for laminar, transitional, and turbulent flow. Velocity

3. Conflito e interdependência na cadeia de suprimentos de marcas próprias
The supply chain management involves participants with conflicting objectives. Attrition situations naturally occur and the use of power defines the conformation of the supply chain. Such attritions can, eventually, modify the product offered to the consumer, in the last loop of the chain. On the private label issue the behavioral dimension of the supply cha

4. Estudo do comportamento carga VS recalque de estacas raiz carregadas a compressão / Study of the load VS settlement behavior of root piles submitted to compression efforts
In this research, the behavior of the curve load versus settlement ofloaded isolated pile to the compression is analyzed, through forecast methods. Two root piles had been assayed, one with 23m oflength and 31 cm of diameter, and the other with length of 12 m and 41 cm of diameter, in order to attribute the behavior of the interaction ground-pile to one or a

5. OPÇÕES REAIS HÍBRIDAS COM APLICAÇÕES EM PETRÓLEO / HYBRID REAL OPTIONS WITH PETROLEUM APPLICATIONS
This methodological and normative thesis extends the modern economic valuation theory of projects under uncertainty, known as real options theory, from the point of view of an oil company that optimizes the allocation of investment and resources. The real options theory is combined with other theories - so the name hybrid real options - in order to perform a

6. It influences of the factor of variable attrition in the evaluation of the Transitory flowing in waterworks / Influencia do fator de atrito variavel na avaliação do escoamento transitorio em sistemas hidraulicos
O transiente hidráulico é definido como a transição entre duas condições de escoamento permanente. Nessa transição a variação das grandezas associadas ao escoamento, principalmente a pressão, é importante no dimensionamento e exploração da instalação hidráulica. Os estudos das situações transitórias e das manobras que as provocaram, são

7. Head loss.set by heterogeneous average in conduits horizontal / Perda de carga provocada por escoamento heterogeneo em condutos horizontais
The head loss of solid-liquid draining mixtures in horizontal forced conduits in the heterogeneous regimen, can be calculated by knowing a parameter «I» of adimensional sediment carrier. This adimensional depends on the draining average speed, on the relative density and the solid grain size, on the conduit diameter, and on experimentally determined consta

8. Função mastigatoria em indios Ianomami
This work is based on the occlusion and masticatory function of two lanomami groups, one of them already contacted for some years, and the other just beginning contact with civilized habits, in order to question the present day concepts of dental occlusion and methods of treatment for oclusal disorders. The evidence of four milIion years of natural history,

9. FRICTION COEFFICIENTS OF SUBCHANNELS AND FLOW DISTRIBUTION IN HEXAGONAL ARRANGEMENTS OF BARS WITH HELICOIDAL SPACERS / COEFICIENTES DE ATRITO DE SUBCANAIS E DISTRIBUIÇÃO DO ESCOAMENTO EM ARRANJOS HEXAGONAIS DE BARRAS COM ESPAÇADORES HELICOIDAIS
O núcleo de um reator rápido, tipo LMFBR, é composto de feixes hexagonais de barras de arranjo triangular com espaçadores helicoidais. Neste trabalho, foi feita uma análise hidráulica dos subcanais lateral e de canto, que juntamente com o interno, compõem o feixe. Foram realizadas medidas de queda de pressão, vazão e temperatura para o escoamento de

10. Telomere attrition and Chk2 activation in human heart failure
The “postmitotic” phenotype in adult cardiac muscle exhibits similarities to replicative senescence more generally and constitutes a barrier to effective restorative growth in heart disease. Telomere dysfunction is implicated in senescence and apoptotic signaling but its potential role in heart disorders is unknown. Here, we report that cardiac apoptosis

11. Induction of Extracellular Matrix-Remodeling Genes by the Senescence-Associated Protein APA-1
Human fibroblasts undergo cellular senescence after a finite number of divisions, in response to the erosion of telomeres. In addition to being terminally arrested in the cell cycle, senescent fibroblasts express genes that are normally induced upon wounding, including genes that remodel the extracellular matrix. We have identified the novel zinc finger prot
