برنج یکی از مهمترین محصولات کشاورزی است که برای افزایش عملکرد آن مقدار زیادی کود ازته مصرف می شود. مهمترین کود ازته که در شالیزارها مصرف می گردد، اوره است که علیرغم میزان بالای مصرف آن، تاثیرش بر افزایش عملکرد برنج بدلیل هدر رفت ازت در حد انتظار نمی باشد. هدر رفت ازت از کودها باعث افزایش هزینه تولید و آلودگی محیط زیست می شود. تحقیقات نشان داده اند که تصعید آمونیاک مهمترین راه هدر رفت ازت از کود...

Lalezar Granitoid Complex is located in the south-east of Urumieh-Dokhtar volcanic belt and Dehaj-Sarduieh belt (Kerman Province). It contains plutonic rocks with granitoid composition and has been intruded into the Eocene volcano-sedimentary rocks. The plutonic rocks have granite to gabbrodiorite composition with dominance of tonalite and diorite rocks. The main mineral phases are sodic plagio...
Rich area’s sub volcanic bodies in southwest of Birjand have intruded into Upper Cretaceous ophiolite mélange. These rocks are in diorite porphyry to monzonite porphyry range and their main texture is porphyry with microgranular groudmass. Plagioclase and green hornblende phenocrysts are made about 70% of these rocks. Plagioclases are andesine with albitic and carlsbad twining and distinct zon...
in this paper, we propose a new full-fuzzy video ratecontrol algorithm (rca) for variable bit rate (vbr) videoapplications. the proposed rca provides high qualitycompressed video with a low degree computational complexity.by controlling the quantization parameter (qp) on a picturebasis, it produces vbr video bit streams. the proposed rcahas been implemented on the jm h.264/avc video codec andth...

Abstract Study question How does a multiple fresh blastocyst transfer policy impacts live birth rate (LBR) and rates (MLBR) in relation to maternal age ? Summary answer Fresh transferring of ≥ 2 blastocysts only increases LBR women above the 36 substantially risk multiples all categories. What is known already Multiple pregnancies after ART are recognized as major complication it significantly ...
The global interest in MgH2 is due to the natural availability of Mg and its capacity retain hydrogen at a concentration up 7.60 wt.%. Despite appealing characteristics ease production on an industrial scale ambient temperature using reactive ball milling (RBM) technique, highly stable chemical with sluggish hydrogenation dehydrogenation rates below 300 °C. Among different methods used improve ...
افزایش روزافزون تعداد کاربران شبکه اینترنت موجب افزایش ترافیک در این شبکه شده است. یکی از مواردی که می تواند علاوه بر شبکه های زمینی به انتقال اطلاعات بپردازد ماهواره ها هستند از این رو پای ماهواره ها هم به این عرضه باز شدهاست. نگهداری می کند تا در صورت درخواستهای آینده برای همان اطلاعات نیازی به بازیابی مجدد آ>ها از شبکه نبوده و بتوان آنها را مستقیما از حافظه بازیابی کرد. با توجه به حافظه محد...
