we report the case of a three-year-old girl who complained from dysphagia and post-prandial vomiting since she was 6months old. several diagnostic work-ups were performed for her problem. upper gi endoscopy was normal but barium swallow revealed an external pressure effect over upper part of the esophagus (figure 1) and the ct angiography of thoracic aorta showed that this external pressure eff...
In their review on mechanical ventilation in severe asthma, Stather and Stewart [1] raise a concern that use of external positive end-expiratory pressure (PEEP) will result in increased total PEEP and worsened gas trapping [1]. Of critical importance to our understanding of whether application of external PEEP will be beneficial is assessment of the presence or absence of expiratory flow limita...
Magnetohydrodynamic(MHD) peristaltic flow of a Couple Stress Fluid through a permeable channel is examined in this investigation. The flow analysis is performed in the presence of an External Magnetic Field. Long wavelength and low Reynolds number approach is implemented. Mathematical expressions of axial velocity, pressure gradient and volume flow rate are obtained. Pressure rise, frictional f...
