OBJECTIVES The purpose of this study was to examine the effects of the use of a vapocoolant blend of pentafluoropropane and tetrafluoroethane (Gebauer's Spray and Stretch) on hip flexion stretching. METHODS Thirty volunteers were randomly assigned to spray and stretch treatment and stretch only control groups. Each group was assessed pre- and posttest on passive and active hip flexion range o...

We show that the conductance $G$ of molecular tunnel junctions wherein charge transport is dominated by a single energy level can be expressed in closed analytic form which exact and valid at arbitrary temperature $T$ model parameter values. On this basis, we single-step tunneling mechanism compatible with continuous thermal transition from weakly $T$-dependent low (Sommerfeld regime) to nearly...

background hamstring muscles play an important role in functional activities and relaxation and most people around the world suffer from the shortened muscles. different methods of repairing were suggested and there were disagreements with regard to determination of one technique with high efficiency. objectives this study aimed to introduce more effective method, either a static stretch or hol...

INTRODUCTION Le Bihan et al (1) proposed using diffusion-weighted imaging (DWI) based on intravoxel incoherent motion (IVIM) to distinguish pure molecular diffusion and microcirculation, or blood perfusion, by acquiring DW data with the diffusion sensitivity parameter b at low values (<200 sec/mm and at high values (>200 s/mm). The ability of IVIM to provide sensitive and specific values for th...

The positive gate-bias temperature stress (PBTS)-induced instability in top gate self-aligned coplanar InGaZnO thin-film transistors is experimentally decomposed into contributions of distinct mechanisms by combining the stress-time-divided measurements and the extraction of subgap density-of-states (DOS) from the optical response of C-V characteristics. It is found that a total threshold volta...

We consider the problems of numerical solution Cauchy problem for an evolutionary equation with memory when kernel integral term is a difference one. The computational implementation associated need to work approximate all previous points in time. In this paper, considered nonlocal transformed into local one; loosely coupled system additional ordinary differential equations solved. This approac...

In present study, the dynamics of stretching-stretching and stretching-bending entanglement in H2O are studied with considering the inherent decoherence process. It is shown that the excitation in the bending vibration can lead to the decrease of the generation rate of stretching-stretching entanglement for the non-superposed state and the degeneration of entanglement for the initial entangled ...

[Purpose] The purpose of this study was to investigate the effects of two different stretching techniques on range of motion (ROM), muscle activation, and balance. [Subjects] For the present study, 48 adults with hamstring muscle tightness were recruited and randomly divided into three groups: a static stretching group (n=16), a PNF stretching group (n=16), a control group (n=16). [Methods] Bot...

Imidazole phosphate and phosphonate solid acids model the hydrogen-bonding networks and dynamics of the anhydrous electrolyte candidate for proton exchange membrane fuel cells. Solid-state NMR reveals that phosphate and phosphonate anion dynamics dominate the rate of long-range proton transport, and that the presence of a membrane host facilitates proton mobility, as evidenced by a decreased co...
