3. Proposta Metodológica Para Avaliação Quantitativa da Fase Rápida da Curva Força-Tempo na Preensão Manual de Pacientes com Doença Renal Crônica / Methodological proposal for quantitative assessment of the fast phase of the handgrip force-time curve with chronic kidney disease patients.
A Doença Renal Crônica (DRC) é caracterizada pela perda da capacidade de filtragem dos rins. O paciente com DRC tem diminuição dos níveis de força muscular e de condicionamento físico, os quais estão diretamente ligados à qualidade de vida e à realização das atividades da vida diária. A atividade física, especificamente o treinamento de força

5. Funcionalization of mesoporous silica with 2-bezothiazolethiol and 3-mercaptopropyltrimetoxysilane for electronalytical application / Funcionalização de sílicas mesoporosas com benzotiazol-2-tiol e 3-mercaptopropiltrimetoxisilano para aplicações em eletroanalítica
Mesoporous silicas were functionalised by immobilisation of organic substances covalently bonded to the silanol groups on the silica surface. SBA-15 nanostructured silica was functionalised by post-synthesis with 2-benzothiazolethiol and silica films modified with 3-mercaptopropyltrimethoxysilane were obtained by direct functionalisation. The characterizatio

6. Estudo da transformação durante o resfriamento continuo e da microestrutura do aço microligado X80 utilizado na construção de tubos para transporte de gás natural e petróleo. / Study of the transformation during the continuous cooling and the microstructure of microalloyed steel X80 used in the building of pipelines for gas and oil transport.
The continuous increase of energy generated from petroleum and natural gas created the need to improve the mechanical properties of microalloyed steels used in gas and oil pipelines, in order to increase their flow with smaller costs and higher reliability. The control of the different phases, morphology of microconstituents like ferrite plus carbide aggrega

7. Propriedades magnÃticas e Ãpticas de filmes finos rugosos
In this dissertation we study the influence of susbtrate roughness on the magnetic and optical properties of polycrystalline permalloy (Py) films and the optical properties of thin silver (Ag) films, when deposited on this support. The surface roughness of the glass substrates was generated by chemical attack with high concentration flouridic acid vapor (HF-

8. Estudo do comportamento de corrosão dos intermetálicos presentes na liga AA 2024-T3, por meio de técnicas de microscopia associada a técnicas eletroquímicas / INVESTIGATION ON THE CORROSION BEHAVIOUR OF THE INTERMETALLICS IN THE AA 2024-T3 ALLOY BY MICROSCOPY ASSOCIATED TO ELECTROCHEMICAL TECHNIQUES.
The AA2024-T3 aluminium alloy is largely used in the aerospace industry. It has high mechanical properties due to the presence of alloying elements, mainly copper, that form finely distributed precipitates coherent with the matrix, during controlled aging treatment. However, during this process, large intermetallics (IMs) are also formed with composition and

9. Development of membrane biosensors and characterization of the interactions between cytochrome c and hybrid bilayer membranes by Surface Plasmon Resonance / Desenvolvimento de biosensores de membranas e caracterização da interação entre citocromo c e bicamadas híbridas por ressonância plasmônica de superfície
The aim of this work was to develop membrane biosensors based on Surface Plasmon Resonance (SPR) and to apply them to study the interactions between cytochrome c (cyt c) and model membranes. SPR is an optical technique that provides high-sensitivity measurements of refractive index (n), allowing the characterization of the adsorption and desorption of molecu

10. Electrodeposition of nickel plates on copper substrates using PC y PRC
Electrodeposition processes using direct current (DC) require the use of additives to control deposit structure and properties as well as current distribution. The Pulse Current (PC) and Pulse Reverse Current (PRC) techniques improve the properties of deposits based on an appropriate selection of the parameters involved. This research evaluates the influence

11. Analysis of the hand grip forces at elderly practicants and non-practicants of regular physical exercises / Análise da força de preensão manual em idosos praticantes e não praticantes de exercícios físicos regulares
Introduction: The hand grip is a very usual task in daily life. To grab or hold any object with hands and manipulate it, a minimum force and dexterity are necessary. In elderly people, due to the natural aging process and loss of muscular force, the hand grip biomechanical parameters can be indicators of total body force, independence and quality of life. Ob
