a design discharge is an important issue in the design process of pressurized irrigation networks. underestimating the desing discharge affect, the required pressure and offtake discharge, increase the cost of the network. because of the lack of a standard and reliable method for this propuse, usually different approches are used by designers. the network fails to provide the required flow rate...

correct selection of manufacturing condition is one of the most important aspects which should be considered in the majority of manufacturing processes,  particularly in the process related to advanced machining process like electrical discharge machining. in electrical discharge machining (edm), dielectric fluid plays an important role since machining characteristics are greatly influenced by ...

the hydrodynamic behavior of approaching flow and the amount of sediment entry into right-angled lateral intakes in diversion dams were investigated using a laboratory channel by experimental measurement and observation. the velocity field upstream of the intake in the main channel and before it at the sluice gate was measured at different elevations of flow at different discharge rates of the ...

Background It is controversial whether shortening the average length of hospital stay and increasing discharge from a rehabilitation facility to home with either health care or outpatient physical therapy is safe and cost-effective. Methods We computed the average length of hospital stay; the rate of discharge to a rehabilitation facility, home with health care, or home with outpatient physic...

The dynami~ cha~:-acteristics of scroll compresso~: operation have been demonstrated and analyzed in a number of papers over the past decade. This paper discusses the modeling methods used to describe the scroll ~ompressor discharge dynamics. Nume~:ous models are required to accurately represent this complex dynamic p~:-ocess. These include the differential mass continuity and polytropic compre...

BACKGROUND With improvements in cardiopulmonary resuscitation (CPR) techniques, the quality and the effectiveness of CPR have been established; nevertheless, the survival rate after cardiac arrest still remains poor. Recently, many reports have shown good outcomes in cases where extracorporeal membrane oxygenation (ECMO) was used during prolonged CPR. Accordingly, we attempted to evaluate the i...

The cardiac rate and rhythm were studied by 24-hour ambulatory electrocardiographic recording in 44 patients before, during, and after being discharged from hospital following an acute myocardial infarction. The first recordings were started 48 hours before discharge, the second on the morning of the day of discharge, and the third 48 hours after discharge (at home). While in hospital and after...

The development of a handheld single and triple chamber atmospheric pressure coaxial dielectric barrier discharge driven by Flyback circuitry for helium and argon discharges is described. The Flyback uses external metal-oxide-semiconductor field-effect transistor power switching technology and the transformer operates in the continuous current mode to convert a continuous dc power of 10-33 W to...
