Agreement with the disulfide stretching frequency-conformation correlation of Sugeta, Go, and Miyazawa.
Two hypotheses have been advanced to explain the conformational dependence of the disulfide stretching frequency of the CCSSCC moiety in unstrained disulfides. Such compounds can adopt conformations that exhibit disulfide stretching bands near 510, 525, and 540 cm-1. Sugeta et al. [Sugeta, H., Go, A. & Miyazawa, T. (1973) Bull. Chem. Soc. Jpn. 46, 3407-3411] have attributed these three bands to...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...

این پایان نامه بدنبال بررسی کاربرد ارزیابی مستمر در یک محیط یادگیری زبان دوم از طریق طرح چهار سوال تحقیق زیر بود: (1) درک توانایی های فراگیران زمانیکه که از طریق برآورد عملکرد مستقل آنها امکان پذیر نباشد اما در طول جلسات ارزیابی مستمر مشخص شوند; (2) امکان تقویت توانایی های فراگیران از طریق ارزیابی مستمر; (3) سودمندی ارزیابی مستمر در هدایت آموزش فردی به سمتی که به منطقه ی تقریبی رشد افراد حساس ا...
15 صفحه اولFuzzy-Logic Based Frequency Controller for Wind Farms Augmented With Energy Storage and PV Systems
To improve the primary frequency response in future low-inertia hybrid power system a fuzzylogic based frequency controller (FFC) for wind farms augmented with energy storage systems(wind-storage system) and intelligent PV farms for the frequency stabilization is proposed inthis paper. Using system frequency deviations the proposed controller provides bidirectionalreal p...
متن کاملCharacterization of CF bonds with multiple-bond character: bond lengths, stretching force constants, and bond dissociation energies.
Isoelectronic C=F(+) and C=O bonds contained in fluoro-substituted carbenium ions, aldehydes, and ketones are investigated with regard to their bond properties by utilizing the vibrational spectra of these molecules. It is demonstrated that bond dissociation energies (BDEs), bond lengths, vibrational stretching frequencies, and bond densities are not reliable descriptors of the bond strength. T...
