In this report, the structures, morphologies, optical, electrical and gas sensing properties of ZnO and ZnO: Na spin-coated films are studied. X-ray diffraction (XRD) results reveal that the films are of a single phase wurtzite ZnO with a preferential orientation along (002) direction parallel to c-axis. Na doping reduces the crystalline quality of the films. The plane surface of ZnO film turne...

introduction autologous plasma-rich platelet (prp) is a human platelet concentrated product which is in low volume of plasma. using prp in rejuvenation and resolution of some cosmetic problems has been already popular in many countries and also in iran. as no study performed in this field in iran and regarding the high prevalence of using prp in society with no validate references in the case o...

This paper considers an idealised solar sail consisting of a uniform, elastic, isotropic square membrane that is prestressed by two pairs of equal and opposite forces applied at the corners. Two wrinkling regimes are identified. The first regime occurs for symmetric and moderately asymmetric loading; it is characterised by small, radial corner wrinkles. The second regime occurs for strongly asy...

In order to develop the performance of bed linen index objectively, first seven properties fabric are selected by twenty-four experts subjectively, and these also give weight for each property according necessity. These total hand value (THV), moisture management, abrasion resistance, air permeability, wrinkle recovery, thermal drape fabric. After selecting characteristic, an integrated is deve...

A buckling solution and a non-linear post buckling solution were employed for the wrinkling analysis of a tensioned Kapton square membrane. The buckling solution with significantly reduced bending stiffness creates localized buckling modes accounting for the wrinkle formation in the membrane. The non-linear post buckling solution with an updated Lagrangian scheme describes the detailed wrinkle ...
