2. Isokinetic performance of ankle evertor and invertor muscles in adolescent female volleyball athletes
Abstract Aims: This study aimed to analyze the muscular performance of evertor and invertor ankle muscles of adolescent volleyball athletes. Methods: The information provided by database concerning the isokinetic evaluation of ankle muscles from 20 female volleyball players between the ages of 14-17 years old were analyzed. The isokinetic dynamometer was

3. Adaptive Fuzzy Sliding-Mode Control of Wheel Slide Protection Device for ER24PC Locomotive
Abstract Wheel Slide Protection Devices (WSPD) are employed in railway vehicles to maximize the average of the possible frictional braking force, which is a nonlinear function of the slip ratio of the wheel sets. In this paper, to control the WSPD, a low-order model is presented and un-modeled dynamics are considered as uncertainties. Due to the nonlinear dy

4. Análise da influência de diferentes razões de sobreposição no desempenho de turbinas eólicas Savonius empregando dinâmica dos fluidos computacional / Analysis of the influence of different overlap ratios on savonius wind turbines performance using computational fluid dynamics
Este trabalho consiste na análise da influência de diferentes razões de sobreposição das pás no desempenho de turbinas eólicas Savonius. A análise é feita utilizando a dinâmica dos fluidos computacional. Utiliza-se o software comercial Star-CCM+ para a solução das equações da continuidade e de Navier-Stokes com médias de Reynolds. Essas equaç

5. Investigação do controle sensório-motor e da relação funcional de torque de rotação do ombro em arremessadores com e sem sintomas de impacto
Repetitive throwing movement causes adaptations to athletes shoulders and predisposes them to the development of impingement symptoms. The objective of this study was to investigate if there are alterations in sensorimotor control and in the functional torque ratio of shoulder rotation in overhead athletes with impingement symptoms and to distinguish these f

6. Non-invasive 3D facial analysis and surface electromyography during functional pre-orthodontic therapy: a preliminary report
OBJECTIVES: Functional orthodontic devices can modify oral function thus permitting more adequate growth processes. The assessment of their effects should include both facial morphology and muscle function. This preliminary study investigated whether a preformed functional orthodontic device could induce variations in facial morphology and function along wit

7. Desequilíbrio muscular e qualidade de vida de indivíduos com osteoartrite e artroplastia total de joelho
A osteoartrite de joelho caracteriza-se por um processo degenerativo da cartilagem articular e do osso subcondral, com a presença de processo inflamatório, dor, rigidez, fraqueza muscular, e que leva a uma incapacidade funcional. É uma doença degenerativa e incapacitante, e que necessita de reabilitação funcional para a melhora do indivíduo. Nos casos

8. Uso do óleo vegetal em motor estacionário de ciclo diesel / Vegetable oil use in stationary engine of diesel cycle
In terms of liquid biofuels, the questions related to alcohol are in a developed level with the creation of a productive chain where all the processes are technologically decided since the production of the sugar cane until the alcohol consumption with the development of the multifuel cars. As for the use of vegetable oils, some barriers must be overcome, ma

9. Estudo da dinamica das transmissões mecanicas por trens de engrenagens planetarias
Vehicular transmissions are the way to adapt the torque supplied by the engine to that required at each moment of the path of a vehicle. Automatic gearboxes are among severa! types oftransmissions. Epicyclic Gear Trains, EGTs, are fundamental components ofthis kind of mechanical transmission. This kind of mechanism have been studied exhaustively trough the y

10. An Examination of the Stretch-Shortening Cycle of the Dorsiflexors and Evertors in Uninjured and Functionally Unstable Ankles
Objective: To determine if there were differences in concentric peak torque/body-weight (PT/BW) ratios and concentric time to peak torque (TPT) of the dorsiflexors and evertors in uninjured and functionally unstable ankles using a stretch-shortening cycle (SSC) protocol on an isokinetic dynamometer.

11. Simultaneous measurement of bacterial flagellar rotation rate and swimming speed.
Swimming speeds and flagellar rotation rates of individual free-swimming Vibrio alginolyticus cells were measured simultaneously by laser dark-field microscopy at 25, 30, and 35 degrees C. A roughly linear relation between swimming speed and flagellar rotation rate was observed. The ratio of swimming speed to flagellar rotation rate was 0.113 microns, which

12. Excitatory drive to the alpha-motoneuron pool during a fatiguing submaximal contraction in man.
1. This study was undertaken to examine changes of excitatory drive to the triceps surae alpha-motoneuron pool during fatiguing submaximal isometric contractions in man. Eight healthy subjects maintained isometric plantar flexions at 30 percent of maximum voluntary contraction (MVC) until the limit of endurance (range, 6-9 min). 2. Excitability of the alpha-
