Narrowly distributed poly(N-vinyl caprolactam) obtained by the MADIX/RAFT process was used for the preparation of novel thermoresponsive gold nanoparticles presenting a sharp reversible response to temperature, which can be easily modulated near the physiological temperature by simply changing the polymer molecular weight or concentration.
A SO3H-functionalized ionic liquid was used as an alternative to conventional inorganic acids in hydroxylamine stabilization, leading to the formation of a novel hydroxylamine ionic liquid salt that exhibits improved thermal stability and reactivity in the one-step, solvent-free synthesis of caprolactam in comparison with hydroxylamine hydrochloride and hydroxylamine sulfate.
in this research, efficiency of iranian forest and rangeland decision making unit was assessed using non-parametric method. inputs and outputs determined by field research and with applying a delphi method the final input and output variables selected. forty five wood-producing units (forestry plans) in three northern iranian province were studied using data envelopment analysis. the efficiency...
در آنالیز کلاسیک مشتق¬پذیری توابع نقش اساسی را ایفا می¬کند. به طور کلی در آنالیز هموار توابع همه جا مشتق پذیر نیستند، اما بحث مشتق پذیری توابع در آنالیز غیر هموار کمی پیچیدتر می¬شود. دراین پایان¬نامه بر آن هستیم که به معرفی چند مشتق برای توابع تعریف شده روی یک فضای باناخ بپردازیم. در ادامه با استفاده از مشتق¬های معرفی شده مفهوم زیر مشتق را بیان می¬کنیم. هدف اصلی ما در این پایان نامه معرفی ε-ز...
I shortly review the present status of the theoretical estimates of ε/ε . I consider a few aspects of the theoretical calculations which may be relevant in understanding the present experimental results. I discuss the role of higher order chiral corrections and in general of non-factorizable contributions for the explanation of the ∆I = 1/2 selection rule in kaon decays and ε/ε . Lacking reliab...
