Secondary surface texture is of great significance to morphological variety and further expands the application areas of electrospun nanofibers. This paper presents the possibility of directly electrospinning grooved polystyrene (PS) fibers using both single and binary solvent systems. Solvents were classified as low boiling point solvent (LBPS): dichloromethane (DCM), acetone (ACE), and tetrah...

In this paper, Focus is on texture as primary feature. Shape and spatial information were secondary features. Texture features derived from nine grid sizes of independent and different Gabor filter banks were incorporated into the CBIR system by taking advantage of the fact that each grid size of filter is suited to capture particular set of localized frequency-images in diverse database. This ...

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

We consider a superconducting state with a mixed symmetry order parameter components, e.g. d + is or d + id ′ with d ′ = dxy. We argue for the existence of the new orbital magnetization mode which corresponds to the oscillations of relative phase φ between two components around an equilibrium value of φ = π 2. It is similar to the so called " clapping " mode in superfluid 3 He − A. We estimate ...

The Oligocene–Miocene deposits of the Asmari Formation are located in SW of the Zagros Mountains of Iran. The lower part of the Asmari Formation consists of an evaporite bed that is termed Basal Anhydrite. Seven sections from four different anticlines were selected and sampled for petrographic and mineralogical analyses .The petrographical examinations were carried out using an optical polarize...

Zaveh copper mineralization is located SE of Torbat-e-Hydarieh in Khorasan Razavi Province, in Khaf-Kashmar-Bardaskan Metallogenic Zone. Geology of the area includes Jurassic and Cretaceous sedimentary rocks and Eocene andesitic to rhyodacitic volcanic rocks. Mineralization is structurally controled and occurred as vein-veilet form with east-west ternding and hosted by Jurassic silicate-cemente...
