background: the objectives of an educational system in a society are based on society's requirements. since personnel knowledge and skill are not qualified with the advantages of science and invention of new tools, new needs are arisen. comparing the curriculum of undergraduate course of operating room of our country with international societies, it seems that this curriculum is not a good one ...

In a scenario characterized by an increasing penetration of non-dispatchable renewable energy sources and the need fast-ramping grid-balancing power plants, EU project GRASSHOPPER aims to setup demonstrate highly flexible PEMFC Power Plant, hydrogen fueled scalable MW-size, designed provide grid support. this work, different layouts proposed for innovative MW-scale plant are simulated optimize ...

Crude brain homogenates of terminally diseased hamsters infected with the 263 K strain of scrapie (PrP Sc) were heated and/or pressurized at 800 MPa at 60 degrees C for different times (a few seconds or 5, 30, 120 min) in phosphate-buffered saline (PBS) of different pH and concentration. Prion proteins were analyzed on immunoblots for their proteinase K (PK) resistance, and in hamster bioassays...

OBJECTIVES To report a case of extensive subcutaneous emphysema introduced during vitrectomy while using an advanced feedback-controlled pressurized infusion system. METHODS Clinical case report of a 56-year-old woman undergoing pars plana vitrectomy for rhegmatogenous retinal detachment of the left eye. The clinical and radiologic findings of the patient's eyes were documented. The mechanism...

This study assessed whether the improper use of pressurized metered-dose inhalers (pMDIs) is associated with decreased asthma control in asthmatics treated by inhaled corticosteroids (ICS). General practitioners (GPs) included consecutive asthmatic outpatients treated by pMDI-administered ICS and on-demand, short-acting beta2-agonists. They measured an asthma instability score (AIS) based on da...

PURPOSE We aimed to investigate the cardiopulmonary effects of pressurized cement insertion in elderly patients undergoing cemented hip hemiarthroplasty. MATERIALS AND METHODS We conducted a randomized prospective study on elderly patients undergoing cemented hip hemiarthroplasty. Patients were divided into pressurized and non-pressurized groups based on the pressure application during cement...

The aim of the study was to assess the prevalence of throat and voice symptoms in asthma patients using pressurized aerosol, metered-dose, inhaled corticosteroid preparations. A questionnaire was administered to hospital out-patients in an asthma clinic and to a control group attending a diabetic clinic. Two hundred and fifty five consecutive out-patients using pressurized aerosol inhaled corti...

Novel smart material and actuator technology will ultimately lead to the development of aerodynamically efficient air vehicles capable of radical shape change that can accomplish various mission types with superior performance. In this research, active skins based upon pressurized flexible matrix composites (FMCs) are investigated for trailing edge flap control of a glider wing. The new active ...
