The present article is an introductory paper in this special issue on synthetic aperture radar (SAR). A short review is presented on the recent trend and development of SAR and related techniques with selected topics, including the fields of applications
This technique assesses drug concentration using a hollow probe and a microdialysis pump. The continued development and validation of the method are constrained since variations in the skin site where the probe is placed would significantly affect the results, and it cannot be used for medications ...
The results show that when using acetone as the organic working fluid, there is a greater tendency of improvement of endogenous character in Pump 2 of around 80%. When using heptane it was manifested that for the turbine there are near to 77% opportunities for improvement, and the use of ...

This study evaluates, heat transfer and fluid flow behavior in a rectangular duct with square roughened ribs mounted on one of the principal wall (solar plate) by computational fluid dynamics software ANSYS (Fluent 6.3.26 Solver). In this study, The Reynolds-Averaged Navier-Stokes analysis is ...
The application of artificial roughness in the form of fine wires or ribs of different geometry on the heat transfer surface has been recommended to increase the heat transfer coefficient by several investigators. The use of artificial roughness on the underside of the absorber plate disturbs the ...
