AIM The first aim of this study was to assess how changes in the mechanical characteristics of the foot/shoe-ground interface affect spatio-temporal variables, ground pressure distribution, sagittal plane kinematics, and running economy in 8 experienced barefoot runners. The second aim was to assess if a special lightweight shoe (Vibram Fivefingers) was effective in mimic the experience of bare...

This study aimed to use the plantar pressure insole for estimating the three-dimensional ground reaction force (GRF) as well as the frictional torque (T(F)) during walking. Eleven subjects, six healthy and five patients with ankle disease participated in the study while wearing pressure insoles during several walking trials on a force-plate. The plantar pressure distribution was analyzed and 10...

background thermal injury is associated with several biochemical and histopathological alteration in tissue. analysis of these objective parameters in research and clinical field are common to determine healing rate of burn wound. negative pressure wound therapy has been achieved wide success in treating chronic wounds. this study determines superficial burn wound healing with intermittent nega...

The aerodynamic characteristics of the wing-in-ground effect (WIG) craft model that has a noble configuration of a compound wing was experimentally investigated and Universiti Teknologi Malaysia (UTM) wind tunnel with and without endplates. Lift and drag forces, pitching moment coefficients, and the centre of pressure were measured with respect to the ground clearance and the wing angle of atta...

Abstract During the ground operation of aircraft, the interaction between the propulsor-induced flow field and the ground may lead to the generation of ground vortices. Utilizing numerical approaches, the source of vorticity entering ground vortices is investigated. The results show that the production of wall-parallel components of vorticity has a strong contribution from the wall-parallel com...

The aerospace community has an increasing interest in developing super sonic transport class vehicles for civil aviation. One of the concerns in such a project is to minimize the sonic boom produced by the aircraft as demonstrated by its ground signature. One approach being considered is to attach a spike/keel on the front of the aircraft to attenuate the magnitude of an aircraft’s ground signa...

Two main results are presented in this paper: Isakov’s Theorem about the impossibility of an analytic continuation of the pressure at a first order phase transition point and Friedli’s work about the restoration of the analytic continuation of the pressure in the van der Waals limit at such a transition point. An exposition of Pirogov-Sinai theory for models with two periodic ground-states is g...

2.1 Structure of the atmospheric boundary layer Wind is moving air caused by pressure differences in the atmosphere, initiated by temperature differences. At large heights (~1000 m) the wind is not perpendicular to the isobars but parallel to it due to the Coriolis force (perpendicular to the wind direction, caused by the rotation of the earth). This wind is denoted the geostrophic wind. G : pr...

Model calculations of Langmuir monolayers: Pressure effects on tilting behavior of idealized amphiphiles" (1996). Model amphiphiles consisting of lines of Lennard-Jones ͑LJ͒ centers are investigated to determine the effect of pressure and molecular geometry on ground-state tilting behavior. Both the amphiphile length and the intramolecular distance between LJ centers is varied. The results give g...

main perennial rivers of gujarat, tapi, narmada, mahi and sabarmatiare meeting arabian sea in gulf of khambhat. the out flow of mahi river intothe sea is decreased due to construction of dams like bajaj sagar, kadana, panamand wanakbori weir. so, tidal effect of sea and sea water intrusion is beingincreased on landward side. moreover, due to erratic nature of rainfall andimproper management of ...
