This work concerns the peristaltic flow of a Williamson fluid model in an inclined asymmetric channel under combined effects of heat and mass transfer. The governing nonlinear partial differential equations are simplified under the lubrication approach and then solved analytically and numerically. The analytical results are computed with the help of regular perturbation and the numerical re...

Abstract. Replacement of organic solvents, in particular chlorinated, aromatic, and polar aprotic ones is an emerging issue that can find a solution the development catalytic reactions water. Nature performs multitude chemical transformations water under mild conditions mediated by enzymes. In nanoconfinement effects enzymes ensure high activity impressive stereoselectivities. Micellar catalysi...

This paper aims at investigating the impacts of introducing cost asymmetry in horizontal merger analysis. In absence efficiency gains, previous literature states negative competitive effects a between symmetric firms. We go beyond and show that result is only likely to hold for low level asymmetry. particular, we build tractable model with three firms which one them has different structure. Aft...

We develop a dynamic principal–agent model to show how imperfect public information and asymmetric beliefs, asymmetric risk attitudes, complementary actions by both parties, and inter-temporal adverse selection arising from the agent’s unobservable actions interact to affect optimal dynamic contracts. Our continuous-time formulation of the model, which features both “hidden actions” and “hidden...

[Purpose] To investigate the effects of two common asymmetric sitting positions on spinal balance. [Subjects and Methods] Thirty-seven healthy subjects in their twenties were enrolled and randomly divided into two groups. Asymmetric positions of resting the chin on a hand and crossing the legs were performed by each group for 1 hour. After 1 hour, the subjects lay in the supine position again a...

abstract background: increase in nitric oxide (no) concentration accompanied by alteration in peritoneal immune defense reactions is involved in the pathogenesis of endometriosis. asymmetric dimethylarginine is an endogenous competitive inhibitor of no synthase. this study was designed to compare no metabolite (nitrite), asymmetric dimethylarginine, and estradiol concentrations in serum and per...
