A new Modular Multilevel Converter with Interleaved half-bridge Sub-Modules (ISM-MMC) is proposed in this article. The ISM-MMC exhibits higher modularity and scalability terms of current ratings respect to a conventional MMC while preserving the typical voltage-level adaptiveness. brings known advantages classical low-voltage, high-current applications making it novel candidate for sector ultra...
تاثیر قطره میتومایسین C و تزریق زیر ملتحمه 5- فلورواوراسیل در درمان نارسایی زودرس بلب (Failing Bleb)
هدف: مقایسه اثربخشی و ایمنی قطره چشمی میتومایسین C (MMC) و تزریق زیر ملتحمهای 5- فلورواوراسیل (5-FU) جهت درمان نارسایی زودرس بلب (Bleb) پس از جراحی ترابکولکتومی یا ترابکولکتومی و فیکوامولسیفیکاسیون، به همراه کارگذاری لنز داخل چشمی (PT+PCIOL). روش پژوهش: در مطالعهای مقایسهای، 37 چشم از 37 بیمار که مستعد به نارسایی زودرس بلب بودند، مورد بررسی قرار گرفتند. قطره چشمی MMC 02/0 درصد چهار مرت...
Gastrointestinal motility disorder is a major clinical manifestation of acute liver injury, and interdigestive migrating motor complex (MMC) is an important indicator. We investigated the changes and characteristics of MMC in rats with acute liver injury. Acute liver injury was created by d-galactosamine, and we recorded the interdigestive MMC using a multichannel physiological recorder and com...
To reduce the cost of bulk power transmission using voltage source converter high-voltage DC (HVDC) technology, a unidirectional hybrid is proposed, where diode rectifier (DR) and modular multilevel (MMC) based on full-bridge (FB) submodules are connected in series side. The FB-MMC controls its to regulate transmitted power. majority via DR considering efficiency superiority only low rating req...
Due to a dramatic increase in grid-connected renewable energy resources, storage systems are interesting and important for future power systems, among which the modular multilevel converter (MMC)-based battery (BESSs) one of most modular, efficient, flexible topologies. Uneven active distribution submodules (SMs) arms an MMC-based BESS is necessary certain applications. The main contribution th...
BMY 25282, a newly designed analogue of mitomycin C (MMC), was assessed for its non-cross-resistant cytotoxic and biochemical action against MMC-resistant human colon carcinoma cells. The analogue has an amidine substituted at position 7 of MMC and has a more efficient intracellular activation to its active species than MMC. In this study we demonstrated that BMY 25282 can overcome MMC resistan...
