BACKGROUND In the Facioscapulohumeral muscular dystrophy (FSHD), the association of ankle muscle impairment with knee, hip and abdominal weakness causes complex alterations of static (postural) and dynamic (walking) balance, increasing the risk of recurrent falls. Stereophotogrammetric system and body-worn gyroscopes were used to focus on locomotor capacity and upper body movements in FSHD pati...

In this paper, the stability of a functionally graded magneto-electro-elastic (FG-MEE) micro-beam under actuation of electrostatic pressure is studied. For this purpose Euler-Bernoulli beam theory and constitutive relations for magneto-electro-elastic (MEE) materials have been used. We have supposed that material properties vary exponentially along the thickness direction of the micro-beam. Gov...

Recently proposed concepts of pericardial surface pressure, as opposed to liquid pressure, have advanced our understanding of the relationship between pericardial and heart chamber pressures. However, the subsequent suggestion that right heart intracavitary pressure equals, or nearly equals, pericardial surface pressure is not strictly consistent with the physiology of pericardial constraint. I...

OBJECTIVE Tidal volume (VT) and volume of gas caused by positive end-expiratory pressure (VPEEP) generate dynamic and static lung strains, respectively. Our aim was to clarify whether different combinations of dynamic and static strains, resulting in the same large global strain, constantly produce lung edema. DESIGN Laboratory investigation. SETTING Animal unit. SUBJECTS Twenty-eight hea...

Stroke Patients To the Editor: We have read with interest the article by Georgiadis et al in the December 2002 issue of Stroke.1 The authors have attempted to examine the integrity of cerebral autoregulation in hypothermic stroke patients. We would like to raise 2 methodological issues. Despite measuring intracranial pressure, the authors have used mean arterial pressure rather than cerebral pe...

Details of pressure distributions, on a two dimensional airfoil oscillating in pitch through stall, in a 0.8 0.8 m low-speed wind tunnel are presented. Pitching occurred about the airfoils quarter-chord axis. Pitch rate, Reynolds number, and oscillation amplitudes were varied to determine the effects on pressure and lift distributions. It was found that mean angle of attack and pitching amplitu...

 Integral bridges are gaining increased popularity because of both economic and fast construction associated with the omission of bearing supports and expansion joints. In the present study the cyclic earth pressure behind integral bridge abutments under traffic surcharges are investigated and compared with that induced behind the abutment of  conventional bridges (with isolated deck and abutme...

When the femoral artery is occluded in the anesthetized clog, the pressure in the distal segment usually declines progressively and approaches a static limit asymptotically. This static limit is independent of the original degree of vasomotor tone except under extreme conditions. It is concluded that the rapid supervention of reactive hyperemia in the dog vitiates the static limit as an index o...
