Analytical Modeling of MHD Flow over a Permeable Rotating Disk in the Presence of Soret and Dufour Effects: Entropy Analysis

Entropy, 2016
The main concern of the present article is to study steady magnetohydrodynamics (MHD) flow, heat transfer and entropy generation past a permeable rotating disk using a semi numerical/analytical method named Homotopy Analysis Method (HAM).

The role of rare copy number variants in early‐onset depression

JCPP Advances, EarlyView.
Abstract Background Depression is a highly heterogeneous condition. Depression with an onset in childhood and early adolescence has a worse clinical course, is more heritable, and shows a lower genetic correlation with other depression subtypes, than does later‐onset depression.

Radiation Effect on MHD Blood Flow Through a Tapered Porous Stenosed Artery with Thermal and Mass Diffusion

International Journal of Applied Mechanics and Engineering, 2019
A mathematical model for MHD blood flow through a stenosed artery with Soret and Dufour effects in the presence of thermal radiation has been studied. A uniform magnetic field is applied perpendicular to the porous surface.

Rayleigh-Marangoni Instability of Binary Fluids with Small Lewis Number and Nano-Fluids in the Presence of the Soret Effect

Fluid Dynamics & Materials Processing, 2010
A general model for two-component transport phenomena applicable for both nanofluids and binary solutions is formulated. We investigate a combined long-wave Marangoni and Rayleigh instability of a quiescent state of a binary (nano-) liquid layer with a non-deformable free surface. The layer is heated from below or from above. The concentration gradient

Effect of HBr on Explosion Limits of Stoichiometric Hydrogen‐oxygen Mixture

International Journal of Chemical Kinetics, EarlyView.
ABSTRACT This work, based on numerical simulations, discusses the effect of HBr as an inhibitor on the explosion limit of stoichiometric hydrogen‐oxygen gas mixture in a closed spherical vessel. The numerical simulation solves the complete governing equations for mass, momentum, species and energy.

The Combined Effects of Variable Viscosity and Thermal Conductivity of An Unsteady Casson Fluid Flow Along a Vertical Porous Channel With Convective Cooling Walls, Using the Bivariate Spectral Local Linearization Method

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This study examines the combined impact of different thermal conductivity and viscosity on unsteady non‐Newtonian Casson fluid flow of incompressible, electrical conductivity in a porous vertical channel with convective cooling walls, uniform magnetic field, and constant pressure gradient.

Photocatalytic Hydrogen Evolution From Self‐Assembled Stacks of Pd–TCPP and Pt–TCPP

Small, EarlyView.
ABSTRACT The present work demonstrates that surfactant‐free precipitation of Pd– and Pt–TCPP in MeOH/H2O yields well‐defined supramolecular architectures (µm‐long nanorods) whose photocatalytic function tracks their metal‐dependent photophysics and stacking.

Levator hiatus area from 21 weeks' gestation to 8 years after first delivery according to vaginal parity: prospective cohort study with an 8‐year recall extension

Ultrasound in Obstetrics &Gynecology, EarlyView.
ABSTRACT Objectives The first aim was to describe longitudinal changes in levator hiatus area from 21 weeks' gestation in the first pregnancy to 1 and 8 years after first delivery, according to subsequent vaginal parity in women with vaginal delivery or Cesarean section (CS) at first delivery.
