The main objective of this paper was to manipulate the Nano Fibrous Scaffold "NFS" surface roughness to achieve a new transdermal drug release profile. To assess the intrinsic mechanical properties of Nylon 6 or polycaprolactam, such as its proper resiliency, it was considered as the matrix. Cetirizine was used as a drug model and was loaded (1% w/v) to polymer solution (30%w/v) before spinning...

OBJECTIVE The purpose of this study was to assess the influence of conditioning methods and thermocycling on the bond strength between composite core and resin cement. MATERIAL AND METHODS Eighty blocks (8×8×4 mm) were prepared with core build-up composite. The cementation surface was roughened with 120-grit carbide paper and the blocks were thermocycled (5,000 cycles, between 5°C and 55°C, w...

A comprossiblo finite voluinc fortuulalioii for largo eddy simulation IWLS been exleiuled to solve a variety of (lows by using dynamic subgrid-scale stress model and dynamic Prandtl number model. The basic features of this finite volume fornmlatioii include a dual time stepping approach with time derivative preconditioning, an implicit low-upper symtiietric Gauss-Seidel scheme, multiblock frame...

Due to the depletion of fossil fuel reserves, it is now more important than ever explore and use alternate forms energy. “Solar energy a promising long-term solution that can meet world's needs. essential we energy-related solutions as soon possible. Solar solution. Artificially roughened solar air heaters perform better smooth ones under same operating conditions. However, artificial roughness...

The use of QuikSCAT data for wind retrievals of tropical cyclones is described. The evidence of QuikSCAT 0 dependence on wind direction for 30-m/s wind speeds is presented. The QuikSCAT 0 show a peak-to-peak wind direction modulation of 1 dB at 35-m/s wind speed, and the amplitude of modulation decreases with increasing wind speed. The decreasing directional sensitivity to wind speed agrees wel...

This paper describes the fabrication of transparent electrodes based on grids of copper microwires using a non-photolithographic process. The process--"abrasion lithography"--takes two forms. In the first implementation (Method I), a water-soluble commodity polymer film is abraded with a sharp tool, coated with a conductive film, and developed by immersion in water. Water dissolves the polymer ...

With temper rolling, which is the final stage of cold rolling manufacturing process, to surface sheet metal materials transferred roughness with specially roughened rolls. In this study, microhardness and microstructural evolution occurring in section along thickness DC04 grade rolled various reduction ratios were investigated. As a result, it was concluded that distribution taken from increase...
