In this paper, a size-dependent first-order shear deformation plate model is formulated in the framework of the higher-order generalized nonlocal strain-gradient (GNSG) theory. This modelemploys ...

   The main purpose of the present investigation is to analyze more comprehensively the size-dependent nonlinear free vibration response of multilayer functionally graded graphene platelet-reinforced composite (GPLRC) nanobeams. As a consequence, both of the hardening stiffness and softening stiffness of size effect are taken into consideration by implementation of the nonlocal str...

The aim of this retrospective study of 56 patients with minor salivary gland tumours (MSGTs) of the upper aerodigestive tract is to present demographic features, distribution of tumours as well as methods and results of treatment performed in our institution over a 10-year period. Of 221 patients with salivary gland tumours, 56 patients with MSGT were selected. There were 36 female and 20 male ...

BACKGROUND Designing functionally efficient recombinant promoters having reduced sequence homology and enhanced promoter activity will be an important step toward successful stacking or pyramiding of genes in a plant cell for developing transgenic plants expressing desired traits(s). Also basic knowledge regarding plant cell specific expression of a transgene under control of a promoter is cruc...

In this study, the free vibration analysis of smart vibration control (SVC) systems based on Reddy – Levinson model and modified strain gradient theory is developed. This system consist of a micro beam at middle and two magneto-electro-elastic (MEE) composite micro beams at top and bottom which connected by enclosing elastic medium and simulated by Winkler and Pasternak foundation. The effects ...

BACKGROUND Intraoral minor salivary glands tumors (MSGT) are uncommon, with geographic variations in frequency and distribution. This study analyzed the clinic-pathologic features of these tumors in Shiraz, southern Iran. METHODS All of cases histopathologically recorded as epithelial MSGT in Pathology Department of Khalili Hospital from 2002 to 2009 were evaluated with regard to patient's ag...

-Dislocation theory is used to invoke a strain gradient theory of rate independent plasticity. Hardening is assumed to result from the accumulation of both randomly stored and geometrically necessary dislocations. The density of the geometrically necessary dislocations scales with the gradient of plastic strain. A deformation theory of plasticity is introduced to represent in a phenomenological...
