33-46Mathematical investigation has been presented to examine the magnetohydrodynamic boundary layer flow of viscous nanofluids bygone a nonlinear stretched plate among cumulative impact of viscous dissipation and joule heating. Physical formulation produced a system of partial differential equations which has been converted into a set of ordinary differential equations through employing suitable similarity variables. For numerical solutions of resulting governing equations of flow, a Keller-box method has been addressed. Results of dimensionless velocity and dimensionless temperature for impacts of various types of nanoparticle along with water base fluid and effects of physical parameters, namely solid volume fraction, nonlinear stretching parameter, magnetic parameter and Brinkmann number have been deliberated via graphs. Additionally, surface shear stress and surface heat flux for selected suitable values of pertinent parameters have been computed and explicated via table

Numerical investigation of unsteady MHD flow and radiation heat transfer past a stretching surface in porous media with viscous dissipation and heat generation/absorption

71-78Viscous dissipation and radiation effects on unsteady flow of laminar incompressible viscous electrically conducting fluid through stretching surface in a porous media with magnetic field and heat generation/absorption have been investigated. Taking suitable similarity variables, the governing boundary layer equations are converted into a set of ordinary differential equations and solved numerically by Runge-Kutta fourth order method along with shooting technique. The effects of the various physical dimensionless parameters such as unsteadiness parameter, permeability parameter, magnetic parameter, radiation parameter, Prandtl number, heat generation/absorption parameters and Eckert number for velocity and temperature distributions have been analyzed in detail through graphical representations. Further skin friction coefficient and Nusselt number at the surface are numerated and compared with previous researchers

Obstetric and neonatal outcome in women with epilepsy

Background: Epilepsy is the second most common neurological disorder complicating pregnancy next to migraine. Both mother and fetus stay at risk due to epilepsy and side effects of antiepileptic’s. This retrospective study was conducted to study fetal and maternal outcome in WWE.Methods: This study was conducted on 55 patients of epilepsy with pregnancy who attended antenatal clinic of our hospital from January 2016 to December 2016. Data was collected using antenatal registers in outdoor settings and medical case sheets in indoor patients and was analyzed statistically.Results: There were a total of 55 WWE in one year duration. Incidence of epilepsy being 0.4% in this study. 11 WWE were not on ante epileptic drug when conceived, while 34 WWE were on ante epileptic drugs when conceived, 8 WWE were newly diagnosed and 2 patients had both psychiatric disorders along with epilepsy. There were 3 IUDs, 4 major congenital malformation and 2 minor malformations. 2 major malformation occurred in patients taking both antipsychotic and ante epileptics since conception.Conclusions: There were a total of 55 WWE in one year duration.

Finite element scheme for MHD forced convection flow near stagnation point and heat transfer by Newtonian heating, constant wall temperature and constant heat flux

Two dimensional, steady, forced convection magnetohydrodynamic flow of an incompressible, viscous electrically conducting fluid in a forward stagnation region of an infinite solid surface with Newtonian heating, constant wall temperature and constant heat flux has been investigated. Governing partial differential equations for the exploration have been formulated and converted to nonlinear ordinary differential equations by inserting convenient variables. An efficient finite element scheme along to Gauss elimination method has been introduced to find the numerical solutions of the resultant equations. Variation in velocity and temperature distributions against the pertinent parameters like magnetic parameter, Prandtl number and Eckert number have been displayed graphically while skin-friction coefficient and Nusselt number have been discussed quantitatively. A comparison of the computational results has been found in excellent agreement with open literature for limiting cases

Uterine necrosis following B Lynch suture: a rare complication

The B-Lynch uterine suture brace is a relatively new technique used for treatment of postpartum haemorrhage. These uterine compression sutures have achieved hemostasis while preserving fertility in many women and thus their efficacy and safety have been time tested. Very few complications have been reported following B Lynch suture. These include Asherman’s syndrome, hematometra, pyometra, localized areas of uterine necrosis and full-thickness defects in the lower uterine segment or uterine fundus and erosion of uterine wall. Herewith, reporting a case of 23-year-old woman who underwent cesarean section for breech presentation. She had atonic PPH for which uterine artery ligation was done along with B-lynch suture. She developed uterine necrosis for which hysterectomy was done. Microsections showed that endometrial cavity was filled with gangrenous slough extending to variable extent in myometrium and cervix

Computational modeling of partial slip effects on hydromagnetic boundary layer flow past an exponential stretching surface in presence of thermal radiation

Numerical analysis of computational modeling is performed to investigate the influence of partial slip on boundary layer flow of electrically conducting incompressible viscous fluid over exponential stretching surface in the presence of thermal radiation. The impact of defining parameters are determined and governing boundary layer equations are reduced to ordinary differential equations by using appropriate similarity transformation. Numerical computation of the problem has been carried out by Runge-Kutta fourth order method in association with quasilinear shooting technique. Effects of magnetic parameter, radiation parameter, Prandtl number, suction or injection parameter, velocity slip parameter and thermal slip parameter on velocity and temperature profiles are computed and illustrated graphically, whereas numerical values of local skin friction coefficient and local Nusselt number are expressed through tabular arrays. Results for non-magnetic flow condition are found in concordance with earlier investigations
