in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...

LPWANs are a class of technologies that have very low power consumption and high range of communication. Along with its various advantages, these technologies also have many limitations, such as low bandwidth, connectionless transmission and low processing power, which has challenged encryption methods in this technologies. One of the most important of these challenges is encryption. The very s...

در این پایان نامه به کاربرد روش عددی شبکه بولتزمن در شبیه سازی جریان سیال غیر نیوتنی پرداخته شده است. این رساله ضمن ارایه معرفی مختصری در راجع به روش شبکه بولتزمن، برخی از معادلات ساختاری که برای سیالات غیر نیوتنی ارایه شده است را معرفی می‏نماید. در این بین، معادلات ساختاریی که جهت شبیه سازی سیالات غیر نیوتنی عمومیت بیشتری دارند مورد توجه قرارگرفته‏اند و در صورت امکان معادله حل تحلیلی این معاد...

in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...

abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
