Patients that present with high-pressure injection injuries most often have hand or digital involvement. Overall, highpressure injection injuries to the hand are uncommon and tend to be occupation related. The usual cause is industrial equipment, with machinery such as grease guns, spray guns and diesel engine injectors accounting for most of these injuries. Materials injected include the follo...
the purpose of this study is to investigate the effect of injection parameters on a heavy duty diesel engine performance and emission characteristics. in order to analyze the injection and spray characteristics of diesel fuel with employing high-pressure common-rail injection system, the injection characteristics such as injection delay, injection duration, injection rate, number of nozzle hole...
Pressure fluctuations during fuel injection are one of the factors that negative effect on performance of diesel engine. These fluctuations are caused by the rapid opening and closing of the nozzles and the creation of pressure waves in the fuel rail. One way to control these pressure fluctuations is to change the injector design and use an accumulator in the injector. This study is performed t...
Introduction: In arthroplasty, spinal anesthesia was preferred to general anesthesia for a variety of reasons due to the use of cement. the side effects of cement on the cardiovascular system of patients, which can be catastrophic, it,s necessary to find appropriate treatment methods to reduce side effects of cement. method: In this clinical trial, 90 patients were arthroplasty candidates divid...

Evaluation of blood pressure changes following the injection of anesthetic drugs containing Adrenaline Dr. H.M. Hashemi* * - Associate professor of Oral and Maxillofacial Surgery Dept. Faculty of Dentistry Tehran University of Medical Sciences. Background and aim: Adrenaline application causes fluctuations in blood pressure. As drugs containing Adrenaline are frequently used in dentistry, the...
Designing and manufacturing the multiple jets simulator and experimental investigation of the multiple jets in crossflow at low velocity ratios have been studied Together with design and build a low-speed wind tunnel. A specific rake is used to determine the flow field pressure and changes in static pressure measured by pressure taps in the near field of the jets. There are generally three regi...
