A Taguchi approach for determination of parametric dependence in absorber tube of parabolic trough solar collector with roughened surfaces
Abstract: The Taguchi experimental design approach is used in this study to offer the ideal design parameters for the absorber tube with roughened surfaces. In order to determine parametric dependence, passive heat transfer augmentation strategies have been used in the parabolic trough receiver in this article by applying the Taguchi approach. So, for better understanding, two case studies are analyzed using two augmentation technique i.e., wire coil and twisted tape inserts. …

Ileal Ureteral Substitution for Long Ureteric Structure/Segment Loss by Yang-Monti Technique. A Single Centre Experience
Abstract: A new technique for replacing the ureter based on the Yang-Monti principle is introduced to overcome the drawbacks of the classic ileal ureter. Between January 2007 and January 2014, ureteral replacement by ileum was indicated in nine patients, long or multiple strictures due to tuberculosis (6), retroperitoneal tumor (1) and iatriagenic ureteric injury during ureteroscopic (2). Exclusion criteria included patients with inflammatory bowel syndrome or irradiated bowel or a non-functioning …
