A study has been carried out to analyze the effect of Magnetic field flow in a porous medium with consider thermal radiation and suction/injection over a permeable stretching wall. We consider wall boundary conditions are distribution of wall temperature, in addition to momentum, both first and second laws of the thermodynamics analyses of the problem are investigated. A set of solution to the ...
Results showed that the way the fluid-wall interaction is modeled in molecular dynamics simulations has a strong effect on the resultant simulation of liquid injection into a gas. It was found that modeling the wall as individual atoms (atomistic model) interacting with the fluid resulted in the fluid remaining in an injection tube absent any pressure or body force to force it into a gaseous re...
Domain walls, nanoscale transition regions separating oppositely oriented ferromagnetic domains, have significant promise for use in spintronic devices for data storage and memristive applications. The state of these devices is related to the wall position and thus rapid operation will require a controllable onset of domain wall motion and high speed wall displacement. These processes are tradi...
BACKGROUND Intramyocardial injection of vascular endothelial growth factor (VEGF) plasmid DNA was studied to demonstrate improvement of regional myocardial function. METHODS Twenty-one pigs that had undergone ligation of the left anterior descending coronary artery were randomly allocated to one of two treatments: intramyocardial injection of pCK-VEGF165 (VEGF group) or pCK-Null (control grou...
Background and Objectives: The proprietary of carbon nanotubes may cause harmful effects on the environment. In the present study, the effects of these nanoparticles on oxidative stress and liver function impairment in Wistar rats were investigated. Materials and Methods: In this experimental study, the multi-wall carbon nanotubes functionalized with carboxylic groups were injected to Wistar r...
In the present study, the effects of intracerebroventricular (ICV) injections of histamine, chlorpheniramine (H1-receptor antagonist) and ranitidine (H2-receptor antagonist) were investigated on visceral nociception induced by an intraperitoneal (IP) injection of acetic acid in rats. The latency time to the beginning of the first abdominal wall contraction (the first writhe) was recorded and th...
The ethylene-fueled flameholding characteristics of a cavity-based scramjet combustor are experimentally and numerically investigated. test facility used the air heater, which heats from room temperature to total 1477 K. A nozzle is installed behind heater outlet increase speed Mach 2.52. Two cavity geometries with different rear-wall heights 8 mm 10 two injection distances upstream cavities 40...
