1. Simultaneous Equations to Estimate Aboveground Biomass of Pinus caribaea var . hondurensis
ABSTRACT This study aimed to develop equations to predict the biomass of trunks, branches, needles and total individual biomass for Pinus caribaea var. hondurensis . A simultaneous equation system was also adjusted. Twenty (20) trees from the experimental area of the State University of Southwest Bahia (UESB), Vitória da Conquista, Bahia, Brazil, were meas

2. Finite Element Simulation of Welding Distortion in Dissimilar Joint by Inherent Deformation Method
Abstract Fusion welding is widely used to join different parts to each other in various industries. However, welding-induced distortions sometimes cause problems such as misalignment during assembling and impose costs for their removal. Thus, it is imperative to predict and mitigate these problems to improve weldment quality and also reduce fabrication cost

3. A fatigue life prediction model of welded joints under combined cyclic loading. / Um modelo para previsão de vida à fadiga de juntas soldadas submetidas a carregamentos combinados.
The main purpose of this work is to develop a practical and robust methodology to evaluate the fatigue life in seam weld joints fabricated with GMAW process when subjected to combine cyclic loading. The maximum linear stress at the typical crack initiation region, better known as hot spot stress, was used to calculate the fatigue life through high cycle fati

4. Uma contribuição à avaliação de desempenho dos principais métodos para a modelagem de cargas nos estudos do compartilhamento das responsabilidades sobre as distorções harmônicas
Dentre os assuntos contemplados pela área da Qualidade da Energia está a questão das distorções harmônicas. A importância do tema tem motivado órgãos reguladores, concessionárias e consumidores a se preocuparem com a matéria, visto que, na atualidade, observam-se crescentes níveis para este indicador da qualidade do fornecimento elétrico. Devido

5. Um estudo simplificado da percepção pública dos benefícios e riscos de centrais termonucleares - sugestões para a comunicação de valor com o público / Public perception on the benefits and risks of nuclear power plants_a simplified study
Public acceptance of the nuclear based electricity generation depends on many variables that can be affected by circumstances and interests, which although seemingly not close to the issue, can strongly influence the final outcome. Explicit or consented positions assumed by opinion makers and some segments of society are subject to episodic waves of interact

6. Uma contribuição à modelagem de complexos eólicos contendo geradores especiais para atenuação das componentes harmônicas
Most of the wind energy conversion systems (WECS) currently in operation in the world use asynchronous generators in the transformation of wind energy into electricity energy. In Brazil, although it is recognized that the parcel of wind farms is still very reduced, it is evidenced that the principle of the employed generation is mainly synchronous. Within th

7. Uma Abordagem Analítica para Análise Não-Linear dos Amplificadores de RF voltada para as Estruturas do Tipo FET / Uma Abordagem Analítica para Análise Não-Linear dos Amplificadores de RF voltada para as Estruturas do Tipo FET
One of the most important characteristics to be maintained with respect to the quality of generic RF amplifiers is the linearity since that the absence of it can generate a series of effects and distortions in the signal to be transmitted. With this constant demand of the discovery of new technologies many additional impositions are imposed on the transmissi

8. Realizações do Sistema Geodésico Brasileiro associadas ao SAD 69: uma proposta metodológica de transformação. / Materialization of the Brazilian Geodesic System associates to 69 SAD: a methodology of transformation.
A transformação de coordenadas entre Sistemas e/ou Redes Geodésicas é um procedimento amplamente utilizado por usuários de informações associadas a coordenadas. A posição de um móvel, feição ou corpo pode ser estabelecida em diferentes Redes, desde que se conheça os parâmetros que as interrelacionam. Do ponto de vista conceitual pode se

9. Why are angles misperceived?
Although it has long been apparent that observers tend to overestimate the magnitude of acute angles and underestimate obtuse ones, there is no consensus about why such distortions are seen. Geometrical modeling combined with psychophysical testing of human subjects indicates that these misperceptions are the result of an empirical strategy that resolves the

10. Calculated distortions of duplex DNA by a cis, syn cyclobutane thymine dimer are unaffected by a 3' TpA step.
Molecular dynamics simulations were performed on the duplex DNA dodecamers d(CGCGAA TT CGCG): d(CGCGAATTCGCG) and d(GCACGAA TT AAG): d(CTTAATTCGTGC), where TT denotes a cis, syn cyclobutane thymine dimer. The constant temperature and pressure algorithm of the AMBER 4.1 molecular-modeling package was used with explicit water and counterions, periodic boundary

11. Interactions Required for Binding of Simian Virus 40 T Antigen to the Viral Origin and Molecular Modeling of Initial Assembly Events
The purified T-antigen origin binding domain binds site specifically to site II, the central region of the simian virus 40 core origin. However, in the context of full-length T antigen, the origin binding domain interacts poorly with DNA molecules containing just site II. Here we investigate the contributions of additional core origin regions, termed the fla

12. Modeling Membrane Deformations and Lipid Demixing upon Protein-Membrane Interaction: The BAR Dimer Adsorption
We use a self-consistent mean-field theory, designed to investigate membrane reshaping and lipid demixing upon interaction with proteins, to explore BAR domains interacting with large patches of lipid membranes of heterogeneous compositions. The computational model includes contributions to the system free energy from electrostatic interactions and elastic e
