OBJECTIVE Total bilirubin is beneficial for protecting cardiovascular diseases in adults. The authors aimed to investigate the association of total bilirubin, red blood cell, and hemoglobin levels with the prevalence of high blood pressure in children and adolescents. METHODS A total of 3776 students (aged from 6 to 16 years old) were examined using cluster sampling. Pre-high blood pressure a...

eart pressure problems are encountered in retaining walls, bulkheads, sheeting and bracing in cuts,culverts, tunnels, and cofferdams. in many cases, the lateral pressure is determined by use of classical earth pressure theories, such as coulomb's, where the equilibrium conditions of a failure wedge of soil is considered. excessive dynamic lateral earth pressure on retaining structures resu...

In this article, a Ranque–Hilsch Vortex Tube has been optimized utilizing axial angles for nozzles. Effect of nozzles angles on the flow behavior has been investigated by computational fluid dynamics (CFD) techniques. A finite volume approach with the standard k–ε turbulence model has been used to carry out all the computations. The dimensions of studied vortex tubes are kept the same for all m...

An extensive experimental study is conducted to examine effects of different winglet-shapes and orientations on the vortex behind a wing, static surface pressure over the wing, and wing wake of a swept wing at various angles of attack. Four types of winglets, spiroid (forward and aft), blended, and winggrid are used in this investigation. Wing static surface pressure measurements are obtained f...

The mechanism of the low temperature oxidation of gaseous acetaldehyde was investigated in the temperature range of 1 50-400?°C. The minor, intermediate and major products were identified and measured quantitatively by sampling directly into the ionization chamber of an MS10-C2 mass spectrometer from the reactor. The formation of H2O, CO, CO2, HCOOH, H2, HCHO, CH3COOH and CH3OH as the major pro...

background thermal injury is associated with several biochemical and histopathological alteration in tissue. analysis of these objective parameters in research and clinical field are common to determine healing rate of burn wound. negative pressure wound therapy has been achieved wide success in treating chronic wounds. this study determines superficial burn wound healing with intermittent nega...

the interaction between the solar wind and the earth’s magnetosphere results in the transport of magnetic flux into the magnetotail and to avoid a continued buildup in the tail, there is a return convection of magnetic flux from the magnetotail into the night-side dipole-like region and from there to the day-side. since there is energetic plasma with this magnetic flux, hence electric currents ...

four patients were studied for intercostals nerve blockade in cholecystectomy. all of the patients were poor risks (class 4) and received premedication before the procedure. intercostals nerve blockade (icnb) of the 7th and 10th thoracic nerves on the right side was performed with lidocaine 1% plus adrenaline 5 ml. at each segment, t7-t10 (a total dose of 20 ml). ventilation was controlled usin...
