The growing evidence for, and acceptance of, the role of anthropogenic CO2 in contributing to potentially dangerous climate change clearly provides a powerful incentive for the development of decarbonized forms of energy generation and storage; indeed, the development of energy technologies that are independent of fossil fuels is widely accepted as being of the highest priority. However, the vi...
Phase-Change Memory (PCM) has the potential to replace DRAM as the primary memory technology due to its non-volatility, scalability, and high energy efficiency. However, the adoption of PCM will require technological solutions to surmount some deficiencies of PCM, such as writes requiring significantly more energy and time than reads. One way to limit the number of writes is by adopting a last-...
در این تحقیق اثر الکترونگاتیوی برای استخلاف های f, cl, no2 , cf3 برروی آروماتیسیته مولکول بنزن مورد مطالعه قرار گرفته است. nics, ase, homa, homo-lumo energy gapsشاخص هایی هستند که برای نمایش تاثیر استخلاف ها به کار برده می¬شوند.علاوه بر این الکترون های انتقالی توسط پیوند سیگما وپای نیز برای همه مولکول های استخلاف شده مورد نظر محاسبه شده¬اند.نتایج بدست آمده برای این روش ها با یکدیگر متفاوت است.ب...
The energy of a graph is the sum of the singular values of its adjacency matrix. A classic inequality for singular values of a matrix sum, including its equality case, is used to study how the energy of a graph changes when edges are removed. One sharp bound and one bound that is never sharp, for the change in graph energy when the edges of a nonsingular induced subgraph are removed, are establ...
The growth in popularity of osteopathic muscle energy technique (MET) over the last two decades with osteopaths, medical practitioners, physiotherapists, chiropractors and remedial therapists is likely testament to its clinical efficacy. The techniques were originally devised and described by Fred Mitchell Snr in the 1940s and 1950s and the first technique manual published in 1979. It is time t...
terms of address as an important linguistics items provide valuable information about the interlocutors, their relationship and their circumstances. this study was done to investigate the change route of persian address terms in the two recent centuries including three historical periods of qajar, pahlavi and after the islamic revolution. data were extracted from a corpus consisting 24 novels w...
objective: losing weight in consequence of appetite loss can be a sign of a serious underlying condition. currently, the most widely prescribed medication for anorexia is cyproheptadine hydrochloride. however, the clinical use of cyproheptadine hydrochloride is limited by its side effects. in iranian traditional medicine, coriandrum sativum stimulates the appetite. therefore, the effect of cori...
Energy, water, and food are facing present and future challenges triggered by climate change, population growth, human behavior, and economics. Management strategies for energy, water, and food are possible through policies, technology, and related education. However, the links between resources (energy, water, and food) and impacting factors (population increase, human behavior, economics, and...
biosorption of two anionic dyes, eosin y and eosin b, from aqueous solution using saccharomyces cerevisiae was investigated in a batch mode. the influence process parameters such as contact time, initial dye concentration, sorbent dosage, ph and temperature of aqueous solution were studied. the maximum adsorption capacities were found to be at 200 and 100 mg g-1 for eosin y and 1 eosin b, respe...
