This paper presents numerical simulations for a MHD convective process in curved channels. The worked suspension consists of water as based hybrid nanofluid and two types the nanoparticles, namely, Cu Al2O3. Two systems governing equations are formulated dusty phases. system is modeled view lubrication approach. mapped to regular computational domain then they solved numerically using fourth or...

Rhythmic movements, such as peristaltic contraction, are initiated by output from central pattern generator (CPG) networks in the CNS. These oscillatory networks elicit locomotion in the absence of external sensory or descending inputs, but CPG circuits produce more directed and behaviorally relevant movement via peripheral nervous system (PNS) input. Drosophila melanogaster larval locomotion r...

Peristaltic flow is a fundamental method of fluid conveyance in engineering, medicine, and the nuclear industry. The peristaltic mechanism applied designing blood pump machines, dialysis other medical devices. current mathematical model developed to investigate Sisko under influence heat transfer by considering variable viscosity, slip effects, thermal conductivity, wall properties. Long wavele...

We defined the sensory-motor characteristics of the lower esophageal sphincter relaxation (LESR) (stimulus threshold volume, response onset, and relaxation period, relaxation magnitude, nadir) during maturation in human neonates. We hypothesized that LESR kinetics differs during maturation and with peristaltic reflex type. Basal and adaptive esophageal motility testing was performed (N = 20 pre...

This paper describes the effects of induced magnetic field and partial slip on the peristaltic flow of a couple stress fluids in an asymmetric channel. The two dimensional equation of couple stress fluid are simplified by making the assumptions of long wave length and low Reynolds number. The exact solutions of reduced momentum equation and magnetic force function have been computed in wave...

The effect of some endogenous components -endogenous opiates, cholecystokinin (CCK), vasoactive intestinal polypeptide (VIP) and somatostatin-as inhibitory or excitatory transmitters in the local nervous pathways involved in peristaltic responses was examined. The peristaltic reflex was studied using a modification of the Trendelenberg preparation. In each preparation, the luminal distens...

Introduction Even with the technological development of infusion pumps, pediatric intensive care nurses are resistant to administer red blood cells (RBC) by linear peristaltic infusion pumps due to the supposed risk of cells damage, despite the need of accuracy in low flow rates. Patient safety can be compromised both by RBC quality decrease due to the pumping mechanism, as well as, by possible...
