abstract background and aims: to identify and isolation of viruses a susceptible cell is need which can be primary or line. the use of primary cells is laborious, time consuming and expensive, while the use of cell lines is much easier and faster. irkhbk cell line was originated from primary cells of bovine kidney by continuous passage. the aim of this study was to introduce the irkhbk cell lin...

background: considering their specific adaption to marine milieus, marine actinomycetes constitute an excellent source for producing unique bioactive substances. they are also important sources of antibiotics and extracellular enzymes, geosmin, and enzymes with potent antibacterial and anticarcinogenic properties and low toxicity. the objective of this study is to isolate actinomycetes producin...

The single-line-to-ground faults with line breaks (SLGFs-LBs) occur more and frequently in distribution networks can cause major safety accidents. It is difficult to distinguish the (SLGFs) resonant grounding systems ungrounding due same electrical characteristics on source side uncertain operation conditions of networks. This paper proposes a method for distinguishing SLGFs-LBs SLGFs. First, s...
