Magnetic field influence on unsteady free convection flow of a second grade fluid near an infinite vertical flat plate with ramped wall temperature embedded in a porous medium is studied. It has been observed that magnitude of velocity as well as skin friction in case of ramped temperature is quite less than the isothermal temperature. Some special cases namely: (i) second grade fluid in the ab...

background: reactive oxygen species (ros) are a group of free radicals that in excessive amounts have negative influence on sperm quality and function. objective: to study the effect of varicocele and its severity on the level of ros in infertile men with clinical varicocele. materials and methods: in this controlled prospective study, 42 men with clinically diagnosed left varicocele and 30 fer...

background: screening of students ´ health problems could lead to timely prevention and control of many health disorders. this study aimed to determine the nationwide prevalence of common disorders through school health screening program in iran methods: this cross-sectional national screening program was conducted in 2007-2008 among first- and third-grade- stu­dents in primary schools, first- ...

The magnetohydrodynamic MHD and rotating flow of second-grade fluid over a suddenly moved flat plate is investigated, where the second-grade fluid saturates the porous medium. The new exact solution is derived by using the Fourier sine and Laplace transforms. Many interesting available results in the literature are obtained as limiting cases of our solution. Finally, some graphical results are ...

An analytic solution of the flow of a third-grade fluid on a porous plate is constructed. The porous plate is executing oscillations in its own plane with superimposed injection or suction. An increasing or decreasing velocity amplitude of the oscillating porous plate is also examined. It is also shown that in case of third-grade fluid, a combination of suction/injection and decreasing/increasi...

Background: Fluid resuscitation is the mainstay of treatment to counteract massive plasma leakage in dengue shock syndrome. We aimed to determine the differences in clinical outcomes and hemodynamic parameters of children with dengue shock syndrome post restrictive and liberal fluid resuscitation.  Materials and Methods: A retrospective observational study of pediatric patients who were betwee...
