Wells turbine is a self-rectifying air turbine which is widely used in oscillating water column energy converter. The Wells turbine will always rotate in the same direction irrespective of the direction of the oscillating airflow. Furthermore the Wells turbine has a simple configuration and structure. This is why the Wells turbine is very commonly used for conversion of wave energy. At present ...

conclusions the result of this study indicated that nephrotoxicity rate among patients treated with vancomycin is under the influence of the poisoning by nephrotoxicants. higher vancomycin trough level was associated with increasing nephrotoxicity rate. results one hundred and fifty-four vap patients’ profiles were reviewed, of whom 110 were eligible. the median age was 33.50 (12 to 94) years a...

combined cycle performance can be improved by improving the performance of gas turbine based topping cycle. amongst various options the effective cooling of gas turbine blade for realizing the higher turbine inlet temperatures is one of the attractive options. the present paper deals with the thermodynam-ic analysis of advanced technology gas/steam combined cycle based power plant having closed...

Patient-ventilator asynchrony/dysynchrony is a mismatch between the patient and ventilator's delivered breaths ability of ventilator to meet demands. Any factor that alters harmony these two components produces asynchrony, which can cause discomfort an increase in patient's work breathing. Delayed cycling occurs when neural time less than mechanical ventilator. Keywords: ventilator, delayed cyc...

Patient–ventilator asynchrony can often be corrected by ventilator adjustment rather than sedation.

the purpose of this study is to improve the aerodynamic performance of wind turbine blades, using the ball-spine inverse design method. the inverse design goal is to calculate a geometry corresponds to a given pressure distribution on its boundaries. by calculating the difference between the current and target pressure distributions, geometric boundaries are modified so that the pressure differ...

in high-pressure axial turbines, when the fluid mass flow is low, the supersonic blades are being used to obtain a high specific work output. to prevent losses due to low blade aspect ratio, the turbine is used in partial admission conditions. the turbine stator is a group of convergence-divergence nozzles that provides the supersonic flow. the design of these nozzles is important, because ther...
