In this article, entropy generation due to natural convection in entrapped trapezoidal cavities filled with nanofluid under the influence of magnetic field was numerically investigated. The upper (lower) enclosure is filled with CuO-water (Al2O3-water) nanofluid. The top and bottom horizontal walls of the trapezoidal enclosures are maintained at constant hot temperature while other inclined wal...

Objective. HDT bed rest condition is a simulated microgravity condition in which subject lies on bed inclined -6 degree feet up. To determine the influence of a simulated microgravity (HDT bed rest) on oral cavity, 10 healthy male volunteers were studied before, during, just after, and after 6 weeks of the simulated microgravity condition of -6° head-down-tilt (HDT) bed rest. Materials and Meth...

Stepwise excavation is an old concept but has become a research subject more, in recent years. It is a conservative approach to treat deep dental caries lesions where the exposure of the pulp is probable. In case of pulpal exposure, Root Canal Therapy (RCT) is the routine treatment method. However, RCT is an expensive treatment, especially in countries like Iran where most of the dental treatme...

The spatial distribution of desorbing O(2) and CO(2) was examined in 193-nm photoinduced reactions in O(2)+CO adlayers on stepped Pt (112)=[(s)3(111)x(001)]. The O(2) desorption collimated in inclined ways in the plane along the surface trough, confirming the hot-atom collision mechanism. In the presence of CO(a), the product CO(2) desorption also collimated in an inclined way, whereas the incl...

The structure of a steady radial thermocapillary flow from the local heat source in cylindrical geometry has been studied numerically. up boundary liquid was partially covered by stationary film an insoluble surfactant, pushed to wall cavity. calculations are fulfilled on base interfacial hydrodynamics equations using mathematical package "Comsol Multiphysics". It is shown that effect symmetry ...
