this study aimed to determine the relationship between suturing and electro-cautery methods of post-tonsillectomy homeostasis in imam khomeini hospital- kermanshah. an analytical study was performed on admitted patient's profiles from 2002-2004. data collection sheet was applied to extract all variables. descriptive and inferential statistics were used for data analysis. during that period 915 ...

comin the present study, co2 removal from natural gas stream has been studied using a flat sheet membrane contactor. a three dimensional mathematical model is developed to describe the process. the model considers the transport of a gas mixture containing carbon dioxide and methane through a flat sheet membrane contactor module. the model is based on the non-wetted mode of operation, in which t...

Paleoclimatic records show that the Greenland Ice Sheet consistently has lost mass in response to warming, and grown in response to cooling. Such changes have occurred even at times of slow or zero sea-level change, so changing sea level cannot have been the cause of at least some of the ice-sheet changes. In contrast, there are no documented major ice-sheet changes that occurred independent of...

The aim of this project is to improve our understanding of the past European and British ice sheets as a basis for forecasting their future. The behaviour of these ice sheets is investigated by simulating them using a numerical model and comparing model results with geological data including relative sea–level change data. In order to achieve this aim, a coupled ice sheet/lithosphere model is d...

In an attempt to provide a better understanding of our finding that regions with contracting left ventricular myofibers need not develop a significant transmural systolic wall thickening gradient, the analytic approach of Costa et al. was applied to the four-dimensional dynamic data obtained 1 and 8 wk after surgical implantation of transmural radiopaque beads in the lateral equatorial left ven...

Promise of Software Components In engineering design, the idea of aggregating standardized components to create a complex system has allowed engineers to create better systems more easily. Components are described in a handbook, where each has a “data sheet” entry. Its data sheet describes what a component does, and equally important, it gives constraints that allow the system designer to decid...

Any planar resistor (channel) close to a conducting layer left floating (gate) forms a capacitor C whose thermal voltage noise (kT/C noise) has a backgating effect on the sheet resistance of the channel that is a powerful source of 1/f resistance noise in planar resistors and, hence, in planar devices. This 1/f spectrum is created by the bias voltage VDS applied to the resistor, which is a dist...

BACKGROUND Intensive care unit is a center to provide comprehensive care for critically ill patients whose condition can be improved by receiving specialized care. The importance of accurate and rapid monitoring of patients at this precise moment is in recording patient data and its comparison with previous data. Monitoring the patient by either devices or direct examination of the nurses requi...
