microdeletion syndromes are contiguous gene deletion syndromes of less than 5 megabases. most often, many of these syndromes are not detectable by routine chromosomal analysis and require more specific testing techniques such as fish or more accurate general coverage like array comparative genomic hybridization. as many of these syndromes are phenotypically recognizable and allow for easy cl...
در سیستم های با ولتاژ کم، نمونه گیری به دلیل تضاد بین رنج دینامیک، خطی بودن، سرعت و مصرف توان مشکل می شود. بنابراین بحث دستیابی به توان، سرعت و دقت مطلوب و نیز کاهش خطای آفست و خطای بهره برای این تقویت کننده ها در این پروژه مورد بررسی قرار گرفته است. مدارهای t/h سریع تر در ساختار حلقه باز عمل می کنند، ولی مشکل اساسی ، عدم دقت مطلوب آنهاست. مدارهای t/h با ساختار حلقه بسته می توانند خطینگی بالا ر...
We perform a comprehensive theoretical and experimental analysis of the use of all-diierent constraints. We prove that generalized arc-consistency on such constraints lies between neighborhood inverse consistency and, under a simple restriction, path inverse consistency on the binary representation of the problem. By generalizing the arguments of Kondrak and van Beek, we prove that a search alg...
in this paper, a new and ecient approach is applied for numerical approximationof the linear dierential equations with variable coecients based on operational matriceswith respect to hermite polynomials. explicit formulae which express the hermite expansioncoecients for the moments of derivatives of any dierentiable function in terms of theoriginal expansion coecients of the function itse...
a new facile route for synthesis of 3- (aryl) -8, 9- di (alkyl) thieno [3,2-e] [1,2,4] triazolo pyrimidines derivative from the same starting material, 2- amino - 4,5 -di (alkyl) thiophene-3- carboxamide, has been developed through heterocyclization of the corresponding arylidene-hydrazino -5,6 -di (alkyl) thieno [2,3-d] pyrimidine under refluxing condition with acetic anhydride followed by air...
در هنگام حفر به کمک روش های تونلسازی مکانیزه و بعد از نصب سیستم نگهداری، بین سطح خارجی نگهداری نصب شده و محیط حفاری شده یک فضای خالی بوجود می آید که می بایست جهت جلوگیری از ریزش خاک و سنگ به درون این فضا و ایجاد نشست سطحی در اثر این ریزش، بوسیله ماده مناسبی پر شود. پر کردن این فضای خالی حلقوی تحت عنوان عملیات backfilling یاد می شود که معمولاً با استفاده از دوغاب های تهیه شده از سیمان، ماسه، آب و...
The paper discusses the expanding scope of the aid-for-trade agenda, the amount of ODA donors are providing in support of trade, the prospects for additional resources, the problems related to identifying market failures, the principles for aid effectiveness, and the main areas for improving the effectiveness of aid-for-trade. It also elaborates a proposal to create aid-for-trade partnerships b...
A new, low band-gap donor-acceptor-type conjugated polymer, PDPP-PER, comprising 3,9-perylene (PER) and diketopyrrolo[3,4-c]pyrrole (DPP) was synthesized. The crystallinity of the synthesized polymer film significantly improved with thermal annealing to 150 °C. The PCE of the PDPP-PER device reached 6.35% with a high open-circuit voltage of 0.79 V.
Programme. However, the findings, interpretations and conclusions expressed in this paper are entirely those of the authors, and should not be attributed to ODA, which does not guarantee their accuracy and can accept no responsibility for any consequence of their use. i Preface This literature review has been prepared as part of a study looking at the financing of agricultural research and exte...
