1. Simulation of Active Eye Motion Using Finite Element Modelling
Abstract Dynamic simulation of human eye movements can significantly improve our understanding about the visuomotor system and also may be used for clinical applications. In this study we have developed a 3D finite element model of the eye orbit. The major novel issues which are considered in this work are using dynamic finite element method for properly ma

2. Theoretical studies of the EPR parameters for Ni2+ and Co+ in MgO
The electron paramagnetic resonance (EPR) parameters (g factors and the hyperfine structure constants) for Ni2+ and Co+ in MgO are theoretically studied from the perturbation formulas of these parameters for a 3d8 ion in octahedral crystal-fields. In the computations, the ligand orbital and spin-orbit coupling contributions are taken into account using the c

3. Analysis of landslides susceptibility and use and landcover evolution of Paraty City - RJ / Análise da suscetibilidade a escorregamentos e as implicações da evolução do uso e cobertura do solo no município de Paraty, RJ
The city of Paraty is located between the Angra dos Reis and Ubatuba municipalities, stages of a numerous episodes of landslides. As the neighboring cities is marked by the presence of the Serra do Mar, where the shallow landslides in the form of translational movements account for most of the evolution of relief. And yet, there is no reference to deaths ass

4. Estimativa de áreas queimadas com produtos modis como subsídio à estimativa de emissões de gases de efeito estufa pela queima de biomassa na Amazônia e Cerrado Brasileiros / Burned area estimation using MODIS fire products as a subsidy for greenhouse gases emissions estimation due biomass burning in the Brazilian Amazon and Cerrado.
At present, the estimates of parameters used in global emissions models are based on low and moderate spatial resolution satellite data, and even though those was an advanced since the rising of the first orbital platforms, it is still necessary to reduce the uncertainty of these estimates. This improvement depends basically, on the capacity of the scientifi

5. Propriedades físicas de planetas extrasolares
ROTATION is one the most important aspects to be observed in stellar astrophysics. Here we investigate that particularly in stars with planets. This physical parameter supplies information about the distribution of angular momentum in the planetary system, as well as its role on the control of dierent phenomena, including coronal and cromospherical emission

6. Sobre a natureza dos processos físicos de aquecimento da atmosfera de estrelas do tipo solar
In the present work, we have studied the nature of the physical processes of the coronal heating, considering as basis significant samples of single and binary evolved stars, that have been achieved with the ROSAT satellite. In a total of 191 simple stars were studied, classified in the literature as giants with spectral type F, G and K. The resu

8. Estudo de soluções sólidas da mulita: fabricação e propriedades.
In the present work a study is made about manufacture of mullite ceramic compacts by synthesis from mechanical mixture of silica (SiO2) and alumina (Al2O3) powders with different compositions by sintering. The silica powder used as starting material for the mullite production was obtained from the calcination of chemically treated rice husk, at temperatures

10. Aproveitamento biotecnológico de resíduos agroindustriais na produção de glucoamilase
The Alto Vale do Itajaí region is a big producer of cassava flour for starch. The processing of the cassava flour generates residues which are usually disposed in the environment in an inadequate way, leading to an environmental impact. This way, the biotechnology proves itself to be an interesting alternative in transforming these residues, which still con

11. Desenvolvimento de um navegador autônomo, usando GPS, aplicado ao controle autônomo de órbita. / Autonomous orbit navigator development, using GPS, applied to autonomous orbit control.
The appearance of modern global positioning systems motivated the study and development of precise and robust systems for autonomous orbit determination of artificial satellites. These systems maintain, independently from human intervention from the ground, a precise knowledge of the satellite orbital state, through the processing of the information, autonom

12. Fotoionização do H2S
We present the results of the application of the Schwinger iterative method in the static-exchange approximation to the photoionization of H2S, from the outermost non-bonding 2b1 orbital. Our results show a Cooper minimum in the asymmetry parameter b at 33 eV (length) and at 36 eV (velocity), as expected for sulphur-containing molecules and assign it to the
