Flavobacterium columnare, the causative agent of columnaris disease in fish, causes millions of dollars of losses in the US channel catfish industry alone, not to mention aquaculture industry worldwide. Novel methods are needed for the control and treatment of bacterial diseases in aquaculture to replace traditionally used chemotherapies. A potential solution could be the use of phages, i.e., b...

در صورتی که بتوان مدت زمان عبور جریان اتصال کوتاه از شبکه را کاهش داد می توان مشکلات فوق را تا حدی محـدود نمود.متأسفانه سیستم های حفاظتی و مدارشکـن های مورد استفاده در سیستم قـدرت برای عملکـرد کامل نیازمند زمانی معـادل چند سیکـل(چند میلی ثانیه)می بـاشد.عبـور مقـادیر بزرگ جریان از خطوط و تجهیزات سیستم قدرت در همین چند سیکل می تواند موجب تخریب جـدی تجهیزات شود.روش دیگر برای حل مشکل جریان هـای اتص...

Wind energy is seen as one of the main pillars renewable energy. However, intermittent nature these sources still poses a major challenge. Moreover, sensitivity to grid faults and response load changes are also concerns. Superconducting devices have been introduced solve storage problems associated with sources. Nevertheless, cost superconducting materials was drawback for their application in ...

Fault current limiters (FCLs) can be considered as key elements in power systems using high temperature superconductors. This analysis takes into account the system benefits provided by the introduction of FCLs in various network configurations. New meshing possibilities, alternative grounding method and increase of power transmission are highlighted. It is the desire of most power system utili...

The miscoordination and malfunctioning of directional overcurrent relays (DOCR) may occur due to a significant change in the fault current level (FCL) network topology, from radial ring caused by renewable energy resource-based distributed generation (RES-DG). In this paper, hybrid time–current–voltage (TCV)-based protection scheme is proposed eliminate DOCR reduce overall operation time DOCRs....

Background: Injuries to the fibular collateral ligament (FCL) seldom occur in isolation and may present with a concomitant injury biceps femoris tendon anterior cruciate (ACL). structures of posterolateral corner (PLC) lead varus rotational instability knee, subjecting ligaments increased forces that result graft failure. Therefore, reconstruction these should be performed concurrently ACL. Ind...

Results The index case was a 10 year old Afro-Caribbean boy who initially presented with a non-progressive developmental delay and severe chilblains (the chilblains improved with methotrexate). He developed transient acute ataxia and flattened affect, with visual and auditory hallucinations. Parotid swelling, arthritis and proximal myopathy were noted, but autoantibodies were negative and compl...
