Background Children undergo painful procedures during care and treatment. This study aimed to determine the effect of distractionon the intensityof pain in children aged 6 to 12 years old. Materials and Methods This clinical trial was conducted on the school-age children, who referred to Imam Hossein Hospital, Iran, Heris city, East Azarbaijan province (Iran) in 2017. In total 48 patients were...

The interaction of a diffusing outgas flow from a sphere nose opposing a hypersonic free stream is studied numerically using the direct simulation Monte-Carlo technique under the transitional rarefied-gas-flow regime conditions at Knudsen numbers from 0.016 to 1.5 and blowing factors from 0.15 to 1.5. Strong influences of the blowing factor (the ratio of outgas mass flux to upstream mass flux) ...

A numerical simulation is conducted to study the laminar flow past a square cylinder confined in a channel (the ratio of side length of the square to channel width is fixed at 1/4) subjected to a locally uniform blowing/suction speed placed at the top and bottom channel walls. Governing equations with boundary conditions are resolved using a finite volume method in pressure-velocity formulation...

Orbital floor fracture due to vigorous nose blowing in the absence of mechanical trauma is rare, only four cases having previously been reported. In each of these cases, predisposing factors have been identified; preceding URTI in three and a history of sino-nasal surgery in the fourth case. We present the case of a 49-year-old woman who developed a maxillary sinus fracture and orbital emphysem...

This dissertation is to discuss the initial-boundary value problem under the third nonlinear boundary condition for a kind of quasi-linear parabolic equations. To apply the maximum value theory and convex method, it is proved that the blowing up of solution in the definite time. And for application, this paper research into a mathematics model of fluids in porous medium. And have got the blowin...

agent technology is an emerging and promising research area in software technology, which increasingly contributes to the development of value-added information systems for large healthcare organizations due to its capability to automatically modify themselves in response to changes in their operating environment. multi agent system (mas) approach is the construction of a complex system as a se...
