Background Walking speed is one of the best measures of overall walking ability. In plantar pressure measurements, walking speed is usually assessed using a stopwatch, photocells, or camera systems. As a simple alternative, contact time can be used but contact time and walking speed are only moderately correlated. Because walking speeds alters foot loading, the centre of pressure might be of mo...

Investigating inter-joint coordination at different walking speeds in young and elderly adults could provide insights to age-related changes in neuromuscular control of gait. We examined effects of walking speed and age on the pattern and variability of inter-joint coordination. Gait analyses of 10 young and 10 elderly adults were performed with different self-selected speeds, including a prefe...

Highly rapid and selective vortex-assisted liquid-liquid microextraction based on solidification of organic drop has been used for determination of cobalt ion. 2-Nitroso-1-naphthol (2N1N) was used as a selective complexing agent to form stable cobalt-2N1N complex which can be extracted with 1-undecanol at a short time by the assistance of vortex agitator system followed by its determination usi...

Introduction: Platelets are small, anucleated cytoplasmic fragments that play an essential role in blood clotting and wound healing. Platelets are routinely stored in plasma for five days at 220C. Aim: Our objective was to assess platelet morphology and function in random donor platelet stored for seven days in platelet additive solution. Methods: The random donor platelet was prepared by PRP m...

With more than 200 species worldwide, Hydrellia Robineau-Desvoidy is the largest genus of the family Ephydridae (Diptera). However, knowledge of this genus is much reduced in Brazil and throughout the Neotropical Region, where only 8 species are known, including one from Brazil (H. xanthocera Cresson). The objective of this study is to review the species of Hydrellia from Brazil, with an emphas...

in this paper, vacuum assisted resin transfer molding (vartm) method was simulated by analytical solution. then the effect of parameters like fiber density, distribution of layer thickness, perform layer thickness, resin viscosity was investigated theoretically. obtained results show that by selecting optimum distribution layer thickness, increasing fiber volume fraction, reducing viscosity of ...

Modeling of wet stirred media mill processes is challenging since it requires the simultaneous modeling complex multiphysics in interactions between grinding media, moving internal agitator elements, and fluid. In present study, a model an HIG5 pilot vertical with nominal power 7.5 kW developed. The based on particle-based coupled solver approach, where fluid modeled particle finite element met...
