1. Inelastic second-order analysis of steel columns under minor-axis bending
Abstract The inelastic second-order behavior of steel structural columns under minor-axis bending is presented in this article. To study this behavior, a nonlinear frame element formulation is adopted in which the steel's plasticity process is accompanied at the nodal points of each finite element through the refined plastic-hinge method (RPHM). A tangent mo

2. MICROEMULSION OF BRAZIL NUT OIL AS A NATURAL PRODUCT TO IMPROVE SUPEROXIDE RELEASE IN HUMAN PHAGOCYTES
The aim of this study was to develop and characterize a Brazil nut oil microemulsion system and determine the effect of this microemulsion on the superoxide release in human phagocytes. The microemulsion was formulated using distilled water, Brazil nut as the oily phase, Sorbitan monooleate, Polysorbate 80, and butan-1-ol. Hydrophile-lipophile balance of Bra

3. USING A DOE AND EIS TO EVALUATE THE SYNERGISTIC EFFECTS OF LOW TOXICITY INHIBITORS FOR MILD STEEL
Abstract Inhibitors are widely used to prevent corrosion in cooling-water systems, and their protective performance can be enhanced by combination. The aim of this paper is to identify possible synergistic effects between four low toxicity substances used as corrosion inhibitors for mild steel in industrial cooling-water systems. Electrochemical measurements

5. Um processo de projetar em arquitetura aplicado a uma escola / An architecture designing process applied on a school
This work deals with a design process in Architecture. It attempts to explore as much as possible the contextual aspects regarding site and building construction. It also means to consider the set of people needs and demands. At the same time speculations on the scheme of building parts must be considered. The final form is the result of this search. This wo

6. SUPPORTING THE DESIGN AND THE INTERPRETATION OF HUMAN-COMPUTER INTERACTION DIAGRAMS REPRESENTED IN MOLIC / APOIO AO DESIGN E À INTERPRETAÇÃO DE MODELOS DE INTERAÇÃO HUMANO-COMPUTADOR REPRESENTADOS EM MOLIC
Personal computer users frequently view an interactive computational system as the user interface itself. Therefore, it´s desirable that such interface be developed in a way they can understand what the system is for, what it allows their users to do and in which way, for whom it´s made etc. Based on Semiotic Engineering, which is the theoretical foundatio

7. MODELOS DE DIMENSÃO REDUZIDA PARA ANÁLISE DAS OSCILAÇÕES NÃO-LINEARES E ESTABILIDADE DE CASCAS CILÍNDRICAS / LOW DIMENSIONAL MODELS FOR NONLINEAR VIBRATION ANALYSIS AND STABILITY OF CYLINDRICAL SHELLS.
The nonlinear vibrations and stability of a fluid-filled cylindrical shell is investigated using reduced order models. First, the nonlinear equations of motion of the cylindrical shell are deduced based on the expressions for the potential and kinetic energy, which are obtained using Donnell shallow shell theory. The internal fluid is considered to be irrota

8. Atividades de ótica exploradas no ensino médio através de reflexões epistemológicas com o emprego do V de Gowin
A Física tem uma maneira própria de olhar a natureza e de estudar seus fenômenos. Por essa razão, o ensino-aprendizagem de Física não pode estar centrado na transmissão de informações, mas sim na construção do conhecimento em um contexto amplo que envolva conteúdos, novas metodologias e novos instrumentos adequados à realidade da escola, que ven

9. Comportamento de fases de soluções binarias e ternarias de poli(etileno-co-alcool vinilico), poli(metacrilato de metila) e dimetilformamida / Phase behavior of binary and ternary solutions of poly(ethylene-co-vinyl alcohol), poly(methyl methacrylate) and dimethylformamide
In this work blends of poly (ethylene-co-vinyl alcohol) (EVOH), a semicrystalline copolymer which combines hydrophobic and hydrophilic segments and poly (methyl methacrylate) (PMMA), an amorphous and hydrophilic polymer were studied. EVOH blends, with ethylene content ranging from 27 to 44 mol% and PMMA were prepared by casting from solutions in DMF, and by

10. Charmed-meson scattering on nucleons in a QCD Coulomb gauge quark model
The scattering of charmed mesons on nucleons is investigated within a chiral quark model inspired on the QCD Hamiltonian in Coulomb gauge. The microscopic model incorporates a longitudinal Coulomb confining interaction derived from a self-consistent quasi-particle approximation to the QCD vacuum, and a traverse hyperfine interaction motivated from lattice si

11. Current conservation in light front dynamics.
We adopt the quasi-potential method as a systematic tool to study relativistic composite systems projected at light-front global time hyperplanes. We address specifically the light-front projection of the Bethe-Salpeter equation for two-bosons, two-fermions and three-bosons systems. The quasi-potential formalism: i) provides a suitable framework for performi
