OBJECTIVE To observe the repercussion of respiratory physiotherapy techniques on the mean arterial pressure (MBP), intracranial pressure (ICP), cerebral perfusion pressure (CPP), jugular venous oxygen pressure (PjvO2) and jugular venous oxygen saturation (SjvO2). METHOD The sample consisted of 20 patients with head trauma. The protocol consisted of physiotherapy techniques application of vibr...

This work studies the free convection heat transfer from a non-isothermal permeable cone with suction and temperature-dependent viscosity. A suitable coordinate transformation is used to transform the governing equations into nonsimilar boundary layer solutions, and the cubic spline collocation method is then employed to solve the obtained governing equations. The local Nusselt number is presen...

INTRODUCTION Rigid endoscopes, now available in varying angles (ranging from 0° to 20°), have given otolaryngologists unparalleled visualization of the paranasal sinuses. However, visualization without proper instrumentation to access difficult-to-reach areas can make sinus treatment frustrating and ineffective. Suction access to different areas within the nose and sinuses is not a straightforw...

Reduction of leakage loss by reducing the height of the cylinder is an effective method to improve efficiency in a rotary compressor. There are, however, few challenges we must face by doing so. Below are some problems for reducing the height of the cylinder. 1) In order to keep the same stroke volume, the diameter of the rolling piston needs to be reduced. This change will create a space betwe...

in this study, the effect of suction and the parameters such as suction amplitude, suction coefficient and suction jet length on naca0012 was evaluated. the turbulence employed model was the rsm model. suction jet is located in 10% of the chord length. the range of suction jet entrance velocity was selected from 0.1 to 0.5 of freestream velocity. the maximum increase in lift to drag ratio was s...

This study presents a finger-triggered portable polydimethylsiloxane suction cup that enables equipment-free microfluidic pumping. The key feature of this method is that its operation only involves a “pressing-and-releasing” action for the cup placed at the outlet of a microfluidic device, which transports the fluid at the inlet toward the outlet through a microchannel. This method is simple, b...

Although various devices have been designed to enable the syringe to be held single handed2l 3 4 we have found the "braced thumb method" as described by Webbl56 to be satisfactory. The lump to be aspirated is steadied between the thumb and forefinger of the left hand while a 20 ml syringe with a No. 18 guage (green) needle is held in the right hand. The needle is introduced into the lesion whil...
