INTRODUCTION Presence of vermiform appendix (non-inflamed or inflamed) in inguinal hernia is called Amyand's hernia in honor to surgeon C. Amyand who published the first case of perforated appendicitis within inguinal hernia in a boy caused by ingested pin. This presentation of foreign body Amyand's hernia appendicitis is very rare, and here we present such a case. CASE PRESENTATION A 6-year-...

Heat sinks are used in industrial equipment to dissipate the excess heat from their heat-generating parts to the ambient. In the last few years, efforts on manufacturing electronic or mechanical devices with less weight, space, and lower cost were spent. Heat dissipation from the heat sink is stalling a big problem which many researchers are trying to solve. The aim of this study is to brief th...

Within the new generation of advanced central solar receivers, microchannel pressurised gas receivers are emerging as reliable and efficient alternatives to operate at high temperatures pressures. This paper presents an optimisation comparative analysis different compact plate-fin type structures, constituting receiver’s absorber panels, classified according fin arrangement inside: plain rectan...

Multi-tube multi-fin heat exchangers are extensively used in various industries. In the current work, detailed experimental investigations were carried out to establish flow/heat transfer characteristics three distinct exchanger geometries. A novel perforated plain fin design was developed, and its performance evaluated against standard louvred fins designs. Experimental setups designed, tests ...
