In this study, the effect of suction flow control on a centrifugal compressor at operation and stall flow rates was investigated using computational fluid dynamics (CFD).The compressor geometry was reconstructed from available open source profile data and the CFD analyses have been performed on this geometry using the appropriate mesh.To validate t

A short superconducting segment can couple attached quantum Games dots via elastic cotunneling (ECT) and crossed Andreev reflection (CAR).Such coupled quantum dots can host Majorana bound states provided that the ratio between CAR and ECT can be controlled.Metallic superconductors have so far been shown to mediate such tunneling phenomena, albeit w

The national HIV seroprevalence in Nigeria has risen steeply from about 3% in 1993 to 5-8% in 2001 and now stands at 4.4%.HIV epidemic continues to be a serious threat to the most populous country in Africa with a population of 140 million, with limited use of antiviral drugs that is taken for life since it only suppresses the virus without complet

The evaluation of the trench stability under the action of ocean waves is an important issue in the construction of an immersed tunnel.In this study, a two-dimensional coupling model of a wave-seabed-immersed tunnel is proposed for the dynamic responses of a trench under wave action in the immersing process of tunnel elements.The porous seabed is c
