In this research in numerical analysis software packages SIGMA / W based on the finite element method was to have been used. For this purpose, during the construction of the dam Kaboodval using behavioral models elastic - plastic and elastic non-homogeneous, non-linear elastic, linear elastic been analyzed and pore pressure, stresses in the body and its meeting with the Data Tools the compariso...

BACKGROUND The physical characteristics of bandage kits, in which different materials are combined, cannot be predicted by laboratory tests. They can only be assessed in vivo by measuring the interface pressure and calculation of stiffness. OBJECTIVE The objective was to investigate pressure and stiffness of some widely used multicomponent, multilayer bandages and to investigate the effect of...

OBJECTIVE To examine whether histological changes in skin owing to intrinsic aging in a laboratory rodent model are modulated by caloric restriction (CR). METHODS The abdominal skin from colony-raised ad libitum-fed Fischer 344 rats and age-matched rats subjected to CR was studied in the light microscope using histological morphometric methods. Animals 4, 12, and 24 months or older were used ...

Concerning the structure of connective-muscular components the authors studied the walls of the terminal segments of the vertebral arteries as well as the basilar artery, utilizing the following staining methods: Azan modified by Heidenheim, Weigert's resorcin-fuchsin, and Weigert modified by van Gieson. It was established that wall of the vertebro-basilar system exhibits a mixed structure, mus...

We report load transfer and mechanical properties of chemically derived single layer graphene (SLG) as reinforcements in poly (dimethyl) siloxane (PDMS) composites. Shear mixing reduced graphene sheets in polymers resulted in a marked decrease of the 2D band intensity due to doping and functionalization. Raman G mode shifts of 11.2 cm(-1)/% strain in compression and 4.2 cm(-1)/% strain in tensi...
