Forced convection of non-darcy flow of ethylene glycol conveying copper(II) oxide and titanium dioxide nanoparticles subject to lorentz force on wedges: Non-newtonian casson model.

The topic of two-dimensional steady laminar MHD boundary layer flow across a wedge with non-Newtonian hybrid nanoliquid (CuO-TiO/CHO) with viscous dissipation and radiation is taken into consideration. The controlling partial differential equations have been converted to non-linear higher-order ordinary differential equations using the appropriate similarity transformations. It is demonstrated that a number of thermo-physical characteristics govern the transmuted model.

Entropy optimized MHD 3D nanomaterial of non-Newtonian fluid: A combined approach to good absorber of solar energy and intensification of heat transport.

Background: The present work provides important insights regarding three dimensional unsteady magnetohydrodynamic flow and entropy generation of micropolar Casson Cross nanofluid subject to nonlinear thermal radiation and chemical reaction. The Buongiorno's nanofluid model featured with Brownian movement and thermophoresis is considered. Realistic aspects namely convective boundary condition, viscous dissipation and joule heating are introduced.

Cellulose-Derived Absorbable Hemostatic Product as a Risk Factor for Mediastinitis after Cardiac Surgery.

We describe the management and control of an outbreak of mediastinitis in a cardiac surgery department. We performed a retrospective cohort study of 87 patients who underwent coronary artery bypass grafting (CABG), valve replacement, or both during a five-month period with a higher than normal number of cases of post-operative mediastinitis. In addition to medical records review, a survey was conducted among surgeons to estimate the frequency of cellulose-derived absorbable hemostatic (CDAH) use.

Anti-inflammatory and analgesic activity of Habbe Gule Aakh, A polyherbal Unani formulation in animal models.

Background: Habbe Gule Aakh is extensively used in Unani medicine for anti-inflammatory and analgesic activity.

Objective: To evaluate anti-inflammatory and analgesic effects of Habbe Gule Aakh on Wistar rats and Swiss mice of either sex.

Materials And Methods: The study was carried out in Wistar rats for anti-inflammatory activity while Swiss mice were used for analgesic activity.

Orbital driven impurity spin effect on the magnetic order of quasi-3D cupric oxide.

Density functional calculations are performed to study the magnetic order of the severely distorted square planar cupric oxide (CuO) and local spin disorder in it in the presence of the transition metal impurities M (=Cr, Mn, Fe, Co and Ni). The distortion in the crystal structure, arisen to reduce the band energy by minimizing the covalent interaction, creates two crisscrossing zigzag spin-1/2 chains. From the spin dimer analysis we find that while the spin chain along [Formula: see text] has strong Heisenberg type antiferromagnetic coupling (J ~ 127 meV), along [Formula: see text] it exhibits weak, but robust, ferromagnetic coupling (J ~ 9 meV) mediated by reminiscent p-d covalent interactions.
