1. Structural and mineralochemical characterization of a pegmatite deposit in the Santa Rosa Pegmatite Field, Minas Gerais Brazil
Abstract The Santa Rosa Pegmatite Field (SRPF), in northeastern Minas Gerais State, is one of the most important gemstone sources in Brazil. The economy of several neighboring cities greatly relies on the trade of its gemstones. However, efforts to improve gemstone mining with practical, scientific methods are scarce, making it a yet inexpensive, marginally

2. Structural Organization of Dental Biofilm Formed in situ in the Presence of Sucrose Associated to Maltodextrin
Resumo Maltodextrinas, derivadas do amido de milho, tem sido adicionadas a alimentos industrializados combinadas à sacarose. Entretanto não estão esclarecidas as propriedades de difusão na matriz do biofilme dental e a estrutura tridimensional de biofilmes multiespécies formados na presença destes carboidratos. Portanto o objetivo deste estudo foi aval

3. Sequence analysis of the cDNA encoding for SpCTx: a lethal factor from scorpionfish venom ( Scorpaena plumieri )
Abstract Background: Lethal factors are multifunctional oligomeric proteins found in the venomous apparatus of Scorpaeniformes fish. These toxins elicit not only an array of biological responses in vitro but also cardiovascular disorders and strong hemolytic, nociceptive and edematogenic activities in vivo. This work describes the cloning and molecular iden

4. Experimental evaluation of the wind effects on an operating power transmission tower
Abstract Static and dynamic effects on power transmission towers can be evaluated by methodologies available in codes, which suggest the use of linear static analysis. By using numerical simulations, it is possible to observe the strong influence of the geometric nonlinear behavior of transmission cables. Dynamic effects also strongly influence this behavior

5. Numeric reconstruction of 2D cellular actomyosin network from substrate displacement
Introduction: One of the fundamental structural elements of the cell is the cytoskeleton. Along with myosin, actin microfilaments are responsible for cellular contractions, and their organization may be related to pathological changes in myocardial tissue. Due to the complexity of factors involved, numerical modeling of the cytoskeleton has the potential to

6. Função de avaliação dinâmica em algoritmos genéticos aplicados na predição de estruturas tridimensionais de proteínas / Genetic Algorithms with Dynamic Fitness Functions Applied to Tridimensional Protein Structure Prediction
The protein structure prediction can be seen as an optimization problem where given an amino acid sequence, the tertiary protein structure must be found amongst many possible by obtaining energy functions minima. Many researchers have been proposing Evolutionary Computation strategies to find tridimensional structures of proteins; however results are not alw

7. Efeitos da restrição proteica gestacional em hipocampo de ratos machos adultos : avaliação da estrutura dendrítica tridimensional, do comportamento e de componentes neuroquímicos = Effects of gestational protein restriction in hippocampus of adult male rats / Effects of gestational protein restriction in hippocampus of adult male rats : evaluation of three-dimensional dendritic structure of hippocampal neurons, behavior and neurochemical components
Studies have demonstrated that maternal nutritional restriction during pregnancy or in early postnatal life results in hippocampus cognitive impairment and structural abnormalities in the 16-wk-old offspring. In an attempt to analyze whether gestational protein restriction might induce learning and memory impairment associated with structural changes in the

8. Determinação estrutural e funcional da enzima 5´-deoxi-5´-metiltioadenosina Fosforilase de Schistosoma mansoni / Structural and Functional Determination of 5´-deoxy-5´-methylthioadenosine Phosphorylase enzyme from Schistosoma mansoni
As doenças parasitárias são uma das maiores causas de morte em países em desenvolvimento, e recebem pouca ou nenhuma atenção das indústrias farmacêuticas para o desenvolvimento de terapias. A esquistossomose mansoni também conhecida como barriga d´água ou doença do caramujo é uma doença parasitária crônica que afeta aproximadamente 207 milhõ

9. Caracterização térmica e estrutural de pós e filmes finos de BaTiO3 sintetizados via método Pechini / Thermal and structural characterization of powders and thin films of BaTiO3 synthesized by Pechini method
Amorphous oxides are chemical compositions whose atomic or molecular configuration does not follow a periodicity like it happens with crystals, which are essentially constituted by oxygen atoms, which has to be the most electronegative element, and other elements. The barium titanate (BaTiO3), amorphous oxide obtained through this work has tetragonal structu

10. An edge-based unstructured mesh formulation for high speed tridimensional compressible flow simulation
Numerical simulation of realistic compressible flows is very important and requires accurate and flexible tridimensional formulations, which should furthermore be robust and efficient. In this work we describe the development of a computational tool for numerical simulation of inviscid compressible 3-D fluid flow problems. This tool uses as the main building

11. Estrutura eletrônica de anéis quânticos
As estruturas nanoscópicas de topologia anelar, ou anéis quânticos, têm atraído o interesse devido a sua simetria rotacional única e à possibilidade de verificar fenômenos quânticos fundamentais. Dentre eles, o estudo de efeitos relacionados à interferência do tipo Aharonov-Bohm aparece com especial ênfase. Cálculos analíticos da estrutura elet

12. Modelagem molecular de uma série de compostos inibidores da enzima integrase do vírus HIV-1 / Molecular modelling for a series of integrase HIV-I inhibitors
An essential step in the HIV life cycle is integration of the viral DNA into the host chromosome. This step is catalyzed by a 32-kDa viral enzyme HIV integrase (IN). HIV-1 IN is an important and validated target, and the drugs that selectively inhibit this enzyme, when used in combination with reverse transcriptase (RT) and protease (PR) inhibitors, are beli
