رآکتور مینیاتوری چشمه نوترونی یک تحقیقاتی از نوع مخزن-استخری است که در آن اورانیم با غنای بالا به‌عنوان سوخت، آب سبک خنک‌کننده و برلیوم بازتابنده استفاده ‌شده است. هنگام بهره­برداری دمای سیال افزایش می­یابد باعث ایجاد فیدبک منفی می‌شود. بر اثر تزریق راکتیویته عین حال یکی مزایای این خصلت ایمنی ذاتی است، اضافی دسترس کاهش‌یافته زمان عملکرد کاهش می‌یابد؛ بنابراین محدودیت­های اصلی MNSR کوتاه (حدود 5...

In this paper, we present a novel continuous mixture of diffusion tensors model for the diffusion-weighted MR signal attenuation. The relationship between the mixing distribution and the MR signal attenuation is shown to be given by the Laplace transform defined on the space of positive definite diffusion tensors. The mixing distribution when parameterized by a mixture of Wishart distributions ...

The present work deals with the development of solid state fermenter for enzymes production and the development of a pilot scale of enzymatic deinking system. The newly developed solid state fermenter, was named FERMSOSTAT®, which was used for the production of cellulases and xylanase using a local isolate; Aspergillus niger USM AI 1. Optimization of enzymes production was carried out and the o...

lodged, more or less forcibly, breaking it into two pieces before removal, as the entire piece could not come away at once. Till then the patient had no knowledge of its presence, but now remembered that seven or eight years before he had a Mow on his forehead, just above the left eyebrow, with a stone causing a big wound. The wound gradually healed by some household applications, but he could ...
