1. The perceptions of physical therapists about facilitators and challenges in the use of different tools for resistance training in COPD patients: a mixed-method study
RESUMO O objetivo do estudo foi quantificar e analisar qualitativamente a percepção de fisioterapeutas sobre facilitadores e barreiras no uso de diferentes ferramentas para treinamento resistido em pacientes com doença pulmonar obstrutiva crônica (DPOC). O método utilizado foi desenvolvido em um centro de reabilitação. Seis fisioterapeutas que partici

2. Development of an ex vivo model of endovenous laser ablation of the great saphenous vein in a pilot study
ABSTRACT PURPOSE: To develop an ex vivo model for the analysis of macroscopic, histological and immunohistochemical changes after experimental endovenous laser ablation (EVLA) of the great saphenous vein (GSV). METHODS: We describe a model produced with glass tubes and introducer sheaths to mimic the physiological conditions of EVLA procedures, such as t

3. A Numerical and experimental study on the crash behavior of the extruded aluminum crash box with elastic support
Thin-walled structures like crash boxes may be used as energy absorption members in automotive chassis. There have been many studies addressing the behaviors of energy absorption members on frontal crash. These researches have attempted to predict the energy absorption and maximum impact load in shell structures. The energy absorption and maximum impact load

4. Influence of fabrication process on the final properties of natural-rubber latex tubes for vascular prosthesis
We report a process of fabrication of latex tubes using the dip-coating technique. We investigated centrifuged latex, with different original viscosities, extracted from the Hevea brasiliensis. The influence of the main deposition parameters (dip-coating velocity, mold material, mold diameter and number of coatings) and post-deposition drying process paramet

5. Study of the force by hamstrings in resisted exercises / Estudo da força gerada pelo grupo muscular isoquiotibial em exercícios resistidos
O desenvolvimento de protocolos de fortalecimento muscular, tanto na reabilitação quanto no treinamento, é realizado por exercícios resistidos, os quais envolvem a aplicação de sobrecargas externas ao músculo exercitado. Estas sobrecargas podem ser do tipo constante ou variável. Dentre os recursos existentes para a aplicação da resistência variáv

6. MODELO PARA ANÁLISE DA ESTABILIDADE DE DUTOS EM MEIO ELÁSTICO / ANALYTICAL MODEL FOR STABILITY ANALYSIS OF TUBES ON ELASTIC MEDIA
With the growth and advance of the petroleum industry there is a need for better transportation facilities for liquid and gaseous materials. Concerns are raised with respect to savings in materials in structures and environmental problemas connected with failures and spills. Usual transportation media are cilindrical tubes, functioning as pipelines embedded

7. A pulsatile flow model for in vitro quantitative evaluation of prosthetic valve regurgitation
A pulsatile pressure-flow model was developed for in vitro quantitative color Doppler flow mapping studies of valvular regurgitation. The flow through the system was generated by a piston which was driven by stepper motors controlled by a computer. The piston was connected to acrylic chambers designed to simulate "ventricular" and "atrial" heart chambers. In

8. AXIAL AND BENDING LOADING OF STRUCTURES CAUSED BY THERMAL DIFFERENCES / SOLICITAÇÃO DE HASTES A FLEXÃO E ESFORÇO AXIAL PROVOCADOS POR DIFERENÇAS TÉRMICAS
Different types of structures submitted to thermal loadings under different conditions of support are studied in this work, with the purpose of analysing the thermal Ratchet Mechanism. This phenomena is na important criteria of safety of nuclear power systems. A first model was used to simulate the bahavior of a structure free of bending, submitted to temper

9. Pulse-wave propagation in an artery with leakage into small side branches.
Linear pulse propagation theory is applied to a network of elastic tubes. The network is specialized to one having a main branch with many low-admittance side branches. Continuum approximations and an asymptotic analysis of side-branch network input admittance reduce the original network to a tapered leaky tube. The outflow law is equivalent to distributed W

10. Polymorphism of DNA–anionic liposome complexes reveals hierarchy of ion-mediated interactions
Self-assembled DNA delivery systems based on anionic lipids (ALs) complexed with DNA mediated by divalent cations have been recently introduced as an alternative to cationic lipid–DNA complexes because of their low cytotoxicity. We investigate AL–DNA complexes induced by different cations by using synchrotron small angle x-ray scattering and confocal mic
