Background and Aim: Considering the great advances and extensive use of cell phones and its effects on the human communications and interactions, investigation of potential negative effects of cell phones on the users' health is necessary. The aim of this study was to determine the effect of the distance between cell phones and brain tissue on the temperature of the central and gray matters of ...
The aims of this paper are review the effects of Propellant Formulation parameters and improving an understanding of mechanisms of burn rate temperature sensitivity. The initial temperature of a solid propellant influences the burn rate, pressure and thrust of the propulsion system. The temperature sensitivity, σp of solid propellant burn rate directly affects the accuracy and performance of th...
nanostructured alumina thin films were coated on stainless steel by sol-gel dip coating method. in order to prevent crack formation, al2o3 films were kept in a solvent bath immediately after coating to reduce the rate of drying. effects of calcination temperature and withdrawal speed on structural properties were analyzed using xrd and sem. topography and thickness of coatings were analyzed by ...
orange (citrus cinensis) is one of the most important among citrus fruits. the thin layer drying kinetics of orange (thompson variety) slice was here experimentally investigated in a convective dryer and through mathematical modeling and by use of thin layer drying models. drying characteristics of oranges were determined using heated ambient air at temperatures from 40 to 80 °c and velocities ...
