1. Exploratory factor analysis for differentiating sensory and mechanical variables related to muscle-tendon unit elongation
ABSTRACT Background Stretching exercises are able to promote adaptations in the muscle-tendon unit (MTU), which can be tested through physiological and biomechanical variables. Identifying the key variables in MTU adaptations is crucial to improvements in training. Objective To perform an exploratory factor analysis (EFA) involving the variables often used

3. Reliability of isokinetic evaluation in passive mode for knee flexors and extensors in healthy children
BACKGROUND: The isokinetic dynamometer has been considered the gold-standard measurement of muscle performance. However, the reliability for the passive mode in children has not been reported to date. OBJECTIVES: The purpose was to evaluate the reliability of the isokinetic dynamometer in passive mode in children. METHOD: Twenty-one healthy child

4. Avaliação da deformação média gerada nos intermediários e na região peri-implantar durante as etapas de confecção da prótese parcial fixa parafusada: análise com strain gauges / Evaluation of abutment and simulated bone tissue mean deformation around dental implants, during fabrication stages of screw-retained fixed partial prostheses: strain gauges analysis
A adaptação passiva e estabilidade têm se tornado os dois pré-requisitos de maior importância na escolha dos materiais e técnicas de confecção em prótese implantossuportada. A proposta deste trabalho foi avaliar, com auxílio dos strain gauges ou extensômetros lineares elétricos, a deformação média ocorrida nos intermediários e na região peri

5. Evaluation of abutment and perimplantar region deformation of implant-supported screwed prostheses: an study using strain gauges / Avaliação da deformação do intermediário e região perimplantar de próteses implanto-suportada unitárias parafusada: estudo através da extensometria
The dental implant depends on the supporting bone for its stability and functional longevity. Mechanical behavior and trabecular bone structure affect the interface with the implant. Such knowledge may provide a basis for improvements in the current implant function and design, decreasing bone crest resorption and failure at bone-implant junction. Adequate q

6. Underactuated manipulator robot control via H2, H∞, H2/H∞, and µ-synthesis approaches: a comparative study
ABSTRACT This paper deals with robust control of underactuated manipulator robots. It presents a comparative study of four combined controllers H2, H∞ , H2/H∞ and µ-synthesis, pluscomputed torque method. These controllers are applied in an actual underactuated manipulator robot with 3 degrees of freedom, of which joints can be configured as active or pa

7. Analise fotoelastica e extensometrica das tensoes induzidas por estruturas de protese sobre implantes fabricadas pelas tecnicas monobloco, soldagem de borda e metodo CAD/CAM / Photoelastic and strain gauge analysis of tensions induced over implant superstructures manufactured through one-pierce technique., bolder soldering and CAD/CAM method, border soldering and one-piece technique
The lack of passivity of the implant supported prosthesis may lead to mechanical and biological disorders over the implants. By the photoelastic and strain gauge analysis, the purpose of this research was to evaluate the stress over the implants after tightening the prosthesis superstructure over five dental implants. A stainless steel matrix was manufacture

8. Mechanical behaviour of non passive multi unit implant restorations / Comportamento mecanico de restaurações multiplas implanto-retidas frente a presença de desajustes marginais
A obtenção de uma estrutura protética passivamente adaptada aos implantes e pilares de conexão tem sido sugerida como fundamental para se evitar falhas mecânicas e biológicas nas reabilitações implanto-retidas. Um melhor entendimento dos efeitos da deficiência de passividade poderia ajudar a entender a mecânica destas falhas. O objetivo desta tese

9. Determinação de níveis ótimos de passividade em prótese sobre implante em função da deformação dos intermediários / Optimum passivity levels of implant prosthesis according to abutment deformation
Passive fit has been considered one of the most important requirements for the success of implant supported prostheses. This in vitro study investigated the abutment deformation of an implant-supported prosthesis after screw tightening of palladium-silver and cobalt-chromium prosthetic cylinder. A master model was used to simulate a human mandible with five

11. Distribuição das tensões geradas em implantes interconectados com barra dolder, após solda a laser
The Implant-retained prostheses need passivity and justness in their settlement, which are considered prerequisites for the osseointegration success. To minimize distortions and to promote passive settlement it is used the cut and solder of the piece. This work investigated, through photoelasticity, the distribution of stress generated by implants interconne
