the available shear correction factors have mainly been developed for homogeneous isotropic plates and/or assuming that no shear tractions are imposed on the top and bottom surfaces of the plate. in the present research, a more general case of a circular functionally graded plate subjected to non-uniform normal and shear tractions at the top and bottom surfaces is considered. these non-uniform ...

Internal radiation was investigated using the finite volume method for the heat exchanger method (HEM) growth of oxide crystals. Special attention was devoted to the temperature and thermal stress distributions in the bottom region of the grown crystal at the end of the solidification process. The numerical results show that internal radiation strongly strengthens heat transport through the cry...

in order to study the effect of drought stress and harvesting stages on quantitative and qualitative yields of coriander (coriandrum sativum l.) this experiment was conducted on split plot based on a randomized completely block design with 3 replications in torbat-e heydariyeh university, iran, during growing season of 2010-2011. treatments were drought stress (in three levels no stress: contro...

We examined the impact of simultaneous bottom-up visual influences and meaningful social stimuli on attention orienting in young children with autism spectrum disorders (ASDs). Relative to typically-developing age and sex matched participants, children with ASDs were more influenced by bottom-up visual scene information regardless of whether social stimuli and bottom-up scene properties were co...

Parameters of gear flanks, such as roughness, hardness, and residual stress, impact their working performance. Therefore, it is essential to optimize these parameters for increasing gears’ life. Thus, this study combined the meshing theory ultrasonic surface rolling technology presented an innovative design realize burnishing. First, dimensions burnishing device with two nodes integrated a at b...
