تقاضای روزافزون برای منابع توان کوچکتر و کارآمدتر برای تجهیزات الکترونیکی فشردهتر، منجر به روی آوردن به مبدلهای dc/dc جدید شده است. مزایای مبدلهای dc/dc کاملاً شناخته شدهاند که عبارتند از چگالی توان بالا و بازدهی خوب. کنترل صحیح این مبدلها از اهمیت زیادی برخوردار است. در این میان روش کنترلی غیرخطی به دلیل پاسخ دینامیکی خوب، مقاوم بودن و رفتار پایدار در برابر تغییرات بار و ولتاژ ورودی توجه خاصی ر...

Culture of lymphocytes from adult Xenopus laevis (Daudin) (a pipid anuran amphibian) with mitogens (PHA, ConA, LPS and PWM) reveals a wide variation in the mitogen sensitivity of these cells: relatively high concentrations of mitogen are required to stimulate Xenopus lymphocytes compared with the concentrations appropriate for mammalian lymphocytes. Significantly better responses are obtained u...

Relationships of the pipid frog genus Silurana (= Xenopus tropicalis group of some authors) are of particular interest to developmental and molecular biologists because of the purported ancestral (i.e., unduplicated) karyotype of S. tropicalis relative to the genus Xenopus. Although most previous studies have assumed that Silurana is the sister group of Xenopus, recent morphological work sugges...

1. The purpose of this study was to compare oocytes from the pipid frogs Xenopus tropicalis and Xenopus laevis, with respect to their utility for studying Ca(2+) signalling mechanisms and for expression of heterologous proteins. 2. We show that X. tropicalis oocytes possess an intracellular Ca(2+) store that is mobilized by inositol (1,4,5) trisphosphate (IP(3)). Ca(2+) signalling is activated ...

Amphibians are important vertebrates in toxicology often representing both aquatic and terrestrial forms within the life history of the same species. Of the thousands of species, only two have substantial genomics resources: the recently published genome of the Pipid, Xenopus (Silurana) tropicalis, and transcript information (and ongoing genome sequencing project) of Xenopus laevis. However, ma...
