Recently, the topological properties of composite vortices, i.e., superposition between vortex modes a different order, have proven effective in manipulating radiation patch antennas and making them suitable for new operative scenarios. In this paper, we exploit these to design multi-antenna system exhibiting both pattern- polarization-diversity. The low mutual coupling possibility steer two or...

In this study, the fatigue behaviors of non-patched and patched aluminum pipes were investigated numerically. The Finite Element Method was used for analysis in study. implemented with Ansys Workbench (15.0) program. Al 6063 type pipe, DP-460 adhesive [0/90]2 reinforced angled glass-epoxy composite patch material analyzes. As a result numerical it observed that size is an effective parameter st...

background: cutaneous manifestations are commonly observed in the neonatal period. it is important to differentiate physiologic skin lesions from pathologic ones to avoid parents’ concerns. regarding this, the current study aimed to investigate the frequency and localization of salmon patch (sp) and mongolian spot (ms) in iranian newborns to assess the potential relationship between the neonata...

Here we report a novel approach for preparation of a 6-day transdermal drug delivery system (TDDS) as treatment for mild to moderate Alzheimer’s disease. The spray drying method was used to prepare microparticles containing the anti-Alzheimer drug. The content of the drug was determined by High Performance Liquid Chromatography (HPLC) method. The morphology and size range of the microparticles ...

Therapeutic angiogenesis has emerged as a promising strategy to treat various acute and chronic vascular diseases, and to enhance tissue repair and regeneration. 1 Common revascularization therapies include the administration of angiogenic factors, such as vascular endothelial growth factor (VEGF). 2 The success of these therapies greatly relies on the ability to control the spatial organizatio...

This study proposes a vibration suppression technique that uses piezoelectric material to restrict the dynamic amplitudes of cantilever beam. The finite element analysis (FEA) model is created and incorporated with Macro Fiber Composite (MFC8507-P2) in ANSYS framework. A comparative has been performed using three different types materials i.e., Polylactic acid (PLA), PLA Short Carbon Fibers (PL...

the dynamic response of a transversely isotropic, linearly elastic layer bonded to the surface of a half-space of a different transversely isotropic material under arbitrary shape surface loads is considered. with the help of displacements and stresses green’s functions, an analytical formulation is presented for the determination of the displacements and stresses at any point in both surface l...
