1. Reduction of Aqueous Ag+ Steered by Electrochemical Plasma: Connecting the Bulk pH Variation with the Reaction Pathways for Hydrated Electrons
Reduction of silver cations followed by nanoparticle (Ag-NPs) synthesis is a model process to understand the reduction mechanism induced by a discharge over an aqueous surface, termed electrochemical plasma. This work aims at studying the silver reduction reaction steered by electrochemical plasma in the presence of other chemically active plasma-related int

3. Estudo do comportamento de ligações viga-pilar preenchido submetidas a ações cíclicas / Study on behavior of steel beam to CFT column connection subjected to cyclic loading
No presente trabalho foi analisado o comportamento de ligações viga-pilar em estruturas mistas de aço e concreto com o auxílio de simulação numérica e experimentação. A simulação numérica foi realizada no programa DIANA, baseado no método dos Elementos Finitos. Os modelos de ligações analisados são compostos por ligações com parafusos passa

4. Uma Nova EstratÃgia para Renderizar Descontinuidades e SuperfÃcies Intersectantes em Modelos Baseados em Splats / A New Strategy for Render and Surface Discontinuities in Models Based on Intersecting Splats
Splats based models have gained increasing attention due to its potential for rendering complex geometric models efficiently and with high quality. The absence connectivity information of these models allows complex modeling operations, as Boolean operations, and fractures in physics simulations. However, these operations often generate models with edges and

5. Action research with graduate students in nursing about the stresses of daily academic tensions. / Pesquisa-ação com graduandos em enfermagem sobre as tensões do cotidiano acadêmico
In this research, we worked on health education of the university, given the commitment that it faces in relation to a number of limitations of their daily lives. For example, time-consuming for their theoretical and practical training, cultural changes, economic and emotional connection with other circumstances of that period. Then, we propose to investigat

6. Vão e desvãos do eu na ficção tardia de Clarice Lispector
The present dissertation searchs for the deletion of the boundaries between autobiograghy and fiction in Clarice Lispectors late literary work (the texts published in the seventies), focusing on the following books: The stream of life (1973), Body crucifixion (1974) and The hour of the star (1977). In this time a radical change occured in the authors writing

7. Finding invariant tori in the problem of a periodically corrugated waveguide
Some dynamic properties for a light ray suffering specular reflections inside a periodically corrugated waveguide are studied. The dynamics of the model is described in terms of a two dimensional nonlinear area preserving map. We show that the phase space is mixed in the sense that there are KAM islands surrounded by a large chaotic sea that is confined by t

8. Avaliação do comportamento mecânico ao cisalhamento de conectores de barras de aço com ganchos em vigas mistas de madeira laminada colada e concreto
The main objective of this work was to propose a reference specimen for the push-out test of rod-type fasteners in timber-concrete connections. The following experimental tests have been performed in order to achieve the goals of this research: pull-out tests of bonded-in steel rods in wood specimens, pull-out tests of bonded-in steel rods in concrete specim

9. Dinâmica oscilatória na eletrooxidação de etileno glicol / Oscillatory dynamics in the ethylene glycol electrooxidation reaction
In the present work were studied some nonlinear aspects of the catalytic oxidation of ethylene glycol (EG) on platinum electrodes in alkaline media (KOH). The systems dynamics was investigated by means of cyclic voltammetry, current and potential time series, and electrochemical impedance spectroscopy (EIS). The EIS results reveal the presence of a hidden ne

10. "Interação não-linear entre ondas atmosféricas: um possível mecanismo para a conexão trópicos-extratrópicos em baixa-frequência" / Nonlinear interaction among atmospheric waves: a possible mechanism for the tropics-extratropics connection on low-frequency time-scales.
The asymptotic perturbation theory based on multiple scales in time is used to investigate the nonlinear interactions among equatorial waves in an equatorial beta-plane adiabatic primitive equation atmospheric model in isobaric coordinates. The equatorial Rossby, mixed Rossby-gravity, Kelvin and inertio-gravity waves, with several vertical structures, are ob

11. Efeitos de tensão em filmes finos de manganitas estudados por espectroscopia de absorção de raios-X com luz linearmente polarizada
Among the materials exhibiting the Colossal Magnetoresistance e effect, mixed manganite thin films have received special attention due to their potential applications for new generation magneto-eletronic devices. In these systems, the external biaxial strain could be used to tune the magnetism and transport properties if it were possible to settle the exact

12. DESENVOLVIMENTO DE SISTEMAS ESTRUTURAIS SEMI-RÍGIDOS EM AÇO E MISTOS PARA EDIFICAÇÕES RESIDENCIAIS MULTI-FAMILIARES / SEMI-RIGID COMPOSITE SYSTEMS FOR RESIDENTIAL BUILDINGS
Nowadays, despite the substantial increase in structural design knowledge, the semi-rigid connections steel design is still facing resistance from the structural engineers. This fact can be in part explained by few design standards that allows and explains their use, suitable computer programs and the lack of detailed information of the economical advantages
