The survival and growth of the banking industry, on the one hand, requires the trust and satisfaction of individuals in the community, on the other hand, requires financial health. In this research, we seek to evaluate the impact of activity-based management on indices of banking health in the banking system of IR Iran. The activity-based management tools examined in this study are activity-bas...
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
selective desulfurization of thiocarbonyls to carbonyls thioacetalization of aldehydes and ketones a useful reagent system for the dethioacetalization reactions
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
Recent research has indicated that the adoption of CLT in an EFL contexts will create certain challenges. Using Engeström’s (1999) human activity system model, the present study investigated the implementation of CLT-based curriculum which was initiated in 2013 in Iranian public schools. Four groups of participants including 23 language teachers, 17 teacher directors, 23 students, and 20 parent...
in a novel dual bed reactor fischer-tropsch synthesis was studied by using two diffrent cobalt catalysts. an alkali-promoted cobalt catalyst was used in the first bed of a fixed-bed reactor followed by a rutenuim promoted cobalt catalyst in the second bed. the activity, product selectivity and accelerated deactivation of the system were assessed and compared with a conventional single bed react...
implicit and unobserved errors and vulnerabilities issues usually arise in cryptographic protocols and especially in authentication protocols. this may enable an attacker to make serious damages to the desired system, such as having the access to or changing secret documents, interfering in bank transactions, having access to users’ accounts, or may be having the control all over the syste...
اولویت کانال صوت در سیستمهای مخابرات سیار، ارسال گفتار فشرده با استاندارد مخصوص می باشد. بدلیل وجود کدک گفتار خاص کانال صوت، مخابره داده از طریق مودمهای معمولی موجود ممکن نمی گردد. از ویژگیهای منحصر به فرد این سرویس که در ارسال از طریق کانال داده وجود ندارد، امنیت در امر مخابره می باشد. این ویژگی سبب شده است استفاده از این سرویس در کاربردهای امنیتی که عدم شنود اطلاعات در اولویت بالاتری از نرخ م...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
