Importance of covalent bonded two-dimensional monolayer nanostructures and also hydrocarbons is undeniably responsible for creation of new fascinating materials like polyphenylene polymer, a hydrocarbon super honeycomb network, so-called porous graphene. The mechanical properties of porous graphene such as its Young’s modulus, Poisson’s ratio and the bulk modulus as the determinative properties...

Effects of Hall current, ion-slip and Coriolis force on unsteady MHD Couette-Hartmann flow of a viscous incompressible electrically conducting fluid through a porous medium bounded by porous plates in the presence of a uniform transverse magnetic field which is either fixed relative to the fluid or to the moving porous plate is investigated using Laplace transform technique. The expressions for...

Background: One of the main challenges with conventional scaffold fabrication methods is the inability to control scaffold architecture. Recently, scaffolds with controlled shape and architecture have been fabricated using 3D-printing. Herein, we aimed to determine whether the much tighter control of microstructure of 3DP PLGA/β-TCP scaffolds is more effective in promoting osteogenesis than por...

A skin lesion previously unassociated with Crohn's disease is described. Although superficially resembling erythema nodosum it runs a different clinical course and has different histological appearances, the central feature being necrobiotic collagen. The term ;nodular necrobiosis' is suggested.

In recent decades, porous asphalt has been extended for surface drainage in various regions throughout the world. The permeability of porous asphalt has an important role in the performance of asphalt pavements in the rainy weather. The most remarkable problem related to the porous asphalt is its short service time. Considerable efforts have been made to enhance the mechanical properties of por...

We report the radiologic and pathologic findings of an intracerebral schwannoma. MR imaging studies showed a superficially located cystic mass with an enhancing nodule and evidence of peritumoral edema or gliosis.

Religion and spirituality are usually considered as protective factors against a host of negative health outcomes. Recent surveys have documented several associations between religion/spirituality and physical and mental health outcomes. Most of the evidences on the effects of religion on general health suggest that religion commonly plays a positive role. On the other side, religion and spirit...

a simple method for fabrication of highly ordered gold nanorod film is introduced in this article. the procedure is based on thermal evaporation of gold into a porous anodic alumina film (paa). the ppa film was fabricated by combining the hard and mild anodization. this combination effectively decreases the processing time of fabrication of highly ordered porous anodic alumina film with control...

The resolution of present day computed tomography (CT) scanners routinely permits discrimination of gray from white matter with delineation of a gray-white matter interface. Superficially situated extraaxial masses usually preserve the gray-white interface and tend to compress and/or buckle adjacent edematous white matter. This does not occur with superficially situated intraaxial lesions and i...
