We have studied the thermal stability of CdSo.&%.lz nanoparticles embedded in a glass matrix as a function of isochronal thermal annealing from 25 "C to 650 "C. The average size and the size distribution of the particles have been determined from the detailed analysis of optical absorption spectra based on the available results of tight binding calculations and also from the low frequency Raman...
We have successfully demonstrated a long-haul transmission of 32 × 10 Gbit/s and 64 × 10 Gbit/s over singlemode fiber of 650 km and 530 km respectively by using RAMANEDFA hybrid optical amplifier as inline and preamplifier amplifiers. The measured Q-factors and BER of the 32 and 64 channels after 650 and 530 km respectively (16.99–17 dB) and (10 -13 ) were higher than the standard acceptable va...

The Cryogenic Dark Matter Search (CDMS) experiment utilizes discriminating detectors where both the recoil energy and ionization produced by each particle event are simultaneously measured. Here we present our latest results from operating 4 Ge (4 x 250 g) and 2 Si (2 x 100 g) detectors at the shallow Stanford site. Our new WIMP exclusion limit excludes new parameter space for low-mass WIMPS. ©...

The thermochemlcal stablllty of fast oxygen ion conductlng yttria stabillzed blsmuthoxlde (YSB) r solld solutlons containing 22.0 32.5 mol% of yttrla was investigated. It was shown that In the temperature range between 650 740 C the stabilized cublc ~ -phase contalnlng less than 31.8 mol% of yttrla ls not stable durlng long term annealing treatments (>~500 hours). During annealing at 650 C a sl...

The purpose this study was plan the dimensions building's portal structure can withstand loads safely. This research conducted Karang Asem 1, Kuningan, Setia Budi, South Jakarta. final result be concluded ther...
ضایعات کشاورزی یکی از چالشهای پیشروی محققین کشاورزی در قرن حاضر است. هر ساله در کارخانه های گلاب گیری حجم عظیمی از پس ماندهای دیگ های تقطیر باعث آلودگی محیط زیست می شود در حالی که قابل تبدیل به کمپوست می باشند. با توجه به نیاز کارخانه گلاب زهرا واقع در شهر لاله زار شهرستان بردسیر استان کرمان به یک تراکتور با سرعت خزشی برای بکار انداختن کمپوست همزن ها، در فرایند تولید کمپوست از تفاله های گل، هدف...
