We present a 200 nm in-diameter single-bead sensor for the detection of single, unlabeled DNA molecules in solution using fluorescence resonance energy transfer technology. DNA-bound Alexa 488 and Crimson 625 loaded on commercial beads served as the donor and acceptor, respectively. Binding of the target DNA to the single bead sensor induces G-quadruplex stretching, resulting in a decrease in f...
In the scope of our recently completed AQUAFLUOSENSE research and development project, design construction a prototype an electron excitation fluorescence-based analytical instrument family has been carried out for water quality measurement applications. The objective project was to develop new analysis system natural artificial waters, allowing complex, systematic main parameters in situ asses...
in chapter one we will describe definitions and preliminary results to provide the global context of our own results to be presented in detail in the subsequent chapters in chapter two we consider degree-one maps of the circle and we study their rotation set. our main result in this chapter says that if the map is topologically mixing then its rotation interval is nontrivial (that is, not reduc...
Time-resolved fluorescence spectroscopy (TRFS) is a powerful analytical tool for quantifying the biochemical composition of organic and inorganic materials. The potential of TRFS for tissue diagnosis has been recently demonstrated. To facilitate the translation of TRFS to the clinical arena, algorithms for online TRFS data analysis are essential. A fast model-free TRFS deconvolution algorithm b...
in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
ارزیابی تاثیر باکتری محرک رشد (pseudomonas fluorescence) و کود آلی (ورمی کمپوست و کمپوست تفاله شیرین بیان) بر ویژگی-های مورفوفیزیولوژیک گیاه به لیمو و بررسی امکان کاربرد آن به عنوان یک گیاه زینتی انجام شد.صفات مورد بررسی شامل صفات مورفولوژیک، کلروفیل کل، کلروفیل a و b، کارتنوئید کل، میزان و عملکرد اسانس، فعالیت آنتی اکسیدانی و میزان غلظت عناصر n، p و k موجود در گیاه بود.
