1. GPU Finite Element Method Computation Strategy Without Mesh Coloring
Abstract A GPU-adapted Finite Element Method (A-FEM) implementation without using a mesh coloring strategy to avoid race conditions is presented. All the elements are simultaneously processed, and the local data is computed and consolidated into the device memory in a new adapted Coordinate Format data structure (a-COO). The comparison between the proposed s

2. Involvement of memory T-cells in the pathophysiology of chronic lymphocytic leukemia
The role of T-cells in the pathogenesis of chronic lymphocytic leukemia has recently gained much attention due to the importance of the constant interaction between neoplastic B-cells with microenvironment substratum and T-cells. It is believed that these interactions modulate the clinical course of the disease, mainly through the regulation of the expansion

3. Translational realistic expectations of chronic cerebral hypoxemia in rat model after bilateral commom carotid artery ligation. Neurocognitive aspects
PURPOSE: To evaluate the effects of chronic cerebral hypoxia on memory of rats submitted to bilateral common carotid artery ligation (BCCL). METHODS: Every each week, for 16 weeks, 31 rats were tested for memory using a water and land mazes and compared with 30 normal rats (control group A). The variables were expressed by their mean and standard error

4. Metaheurísticas para as variantes do problema de roteamento de veículos: capacitado, com janela de tempo e com tempo de viagem estocástico
A atribuição e o planejamento de rotas de veículos é um problema crucial daadministração de cadeias de suprimentos. No ambiente real é comum encontrarproblemas que envolvam uma quantidade muito grande de clientes e queconseqüentemente fogem do alcance de métodos exatos. Neste contexto, este trabalhovisa desenvolver metaheurísticas capazes de resolv

5. Numerical simulation of the solidification of pure melt by a phase-field model using an adaptive computation domain
In this paper, we present a phase-field model with a grid based on the Finite-Difference Method, for improvement of computational efficiency and reducing the memory size requirement. The numerical technique, which is based on the temperature change of the pure material, enables us to use, in the initial steps of the computation, a very small computational do

6. PARALLEL TOPOLOGICAL SUPPORT FOR FINITE ELEMENT MESHES IN DYNAMIC FRACTURE AND FRAGMENTATION ANALYSES / SUPORTE TOPOLÓGICO EM PARALELO PARA MALHAS DE ELEMENTOS FINITOS EM ANÁLISES DINÂMICAS DE FRATURA E FRAGMENTAÇÃO
Fracture propagation and fragmentation phenomena in solids can be described by Cohesive Zone Models and simulated with the Finite Element Method. Among the computational approaches of recent interest for fracture representation in finite element meshes are those based on cohesive elements. In those approaches, fracture behavior is represented by cohesive ele

7. Etiology and immunology of infectious bronchitis virus
Infectious bronchitis virus (IBV) of chickens is currently one of the main diseases associated with respiratory syndrome in domestic poultry, as well as with losses related to egg production. The etiological agent is a coronavirus, which presents structural differences in the field, mainly in the S1 spike protein. The immune response against this virus is co

8. A função da IL-10 na paracoccidioidomise pulmonar murina. / The role of IL-10 in murine pulmonary paracoccidioidomycosis.
Cellular immunity is the main defense mechanism of hosts infected by the Paracoccidioide brasiliensis (Pb), a dimorphic fungus that causes the most important systemic mycosis in Latin America. IFN-g activated macrophages participate in this activity that is antagonized by IL-10 an anti-inflammatory cytokine. Both, in the human pathology a

9. Primates cognitive maps: analysis of movements and routes of Cebus nigritus based on geographic information system / Mapas cognitivos de primatas: análise de movimentos e rotas de Cebus nigritus apoiada por sistemas de informação geográfica
Capuchin monkeys are remarkable for their flexible foraging behavior, occupying environments with diverse characteristics, and, because of these elements they have the largest geographic distribution among the New World primates. They have skills such as tool use and spatial recognition of their home range when searching for food, relying on both egocentric

10. Development of a pseudoelastic vibration isolator / Desenvolvimento de um isolador de vibração pseudoelástico
A pseudoelasticidade é o comportamento termomecânico da ligas com memória de forma (SMA Shape Memory Alloys) observado na fase austenítica. Este comportamento está fortemente associado a uma transformação de fase martensítica induzida por tensão, e pode envolver deformações recuperáveis de até 10% em algumas ligas, conferindo a estes materiais u

12. Hybrid heuristic strategies for planning and scheduling forest harvest and transportation activities in short term / Estrategias hibridas para um problema de planejamento e escalonamento de atividades florestais em curto prazo
This thesis aimed at studying and solving a planning and scheduling problem stemming from forest harvest and wood transportation activities. Our approach treated a real problem faced by large pulp and paper companies in Brazil. It consists in planning, for a short-term horizon, the harvesting operations in different forest areas and the transportation of the
