Abstract This paper presents the stability-evaluation outcomes of a multimachine power system (MMPS) connected with large-scale hybrid wind farm (WF) and photovoltaic (PV) or wind/PV (HWPF) energy-storage (HESS) consisting vanadium redox flow battery (VRFB) supercapacitor (SC). A probability scheme is used to determine rated proposed HESS, where capacities VRFB-ESS SC-ESS are designed effective...

cerebrovascular disease is one of the leading causes of death in the world, and about one-fourth of cerebrovascular deaths are due to ruptured cerebral aneurysms (ca). hence it is important to find a way to reduce aneurysm formation and its subsequent morbidity and mortality. proteolytic activity capable of lysing gelatin has been shown to be increased in aneurysm tissue and expression of plasm...

Gas insulated transmission lines (GIL) have a wide application prospect in special occasions such as cross terrain power transmission. Metal particle pollution is an important reason for the low insulation performance of GIL. When micron metal particles (MMPs), which are most common engineering, adhere to insulators or high-voltage electrodes, will be reduced. Based on that, this paper mainly s...

Background: Matrix metalloproteases (MMPs) are multi-chain proteins that regulated by tissue inhibitor of metalloproteinases (TIMP) and several other mechanisms. This Includes transcription regulation and protein form secretion. The roles of MMPs in wound healing and tissue repair. In tuberculosis (TB), the activity of MMPs is increased and TIMP inhibitors decrease activity. Therefore, in tuber...

Extracellular matrix metalloproteinases (MMPs) are a family of endopeptydases which recquire a zinc ion at their active site, for proteolityc activity. There are six members of the MMP family: matrilysins, collagenases, stromelysins, gelatinases, membrane MMPs and other MMPs. Activity of MMPs is regulated at the level of gene transcription, mRNA stability, zymogene proteolitic activation, inhib...

Zinc is a trace element that requires for more than 2000 transcription factors regulating cell development, differentiation, and growth of many types including cancer cells. Prior studies reported zinc induced apoptosis in cells, such as glioma, bladder, prostate, breast, melanoma. The effects cutaneous squamous carcinoma (SCC) have not been formally assessed. Two SCC lines (A431 HSC-5) were cu...
