simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
development of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles
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...
Water compatibility and organic transformations of organo-Zintl deltahedral clusters.
We report the remarkable stability of di-substituted organo-Zintl deltahedral clusters in the presence of water. This has been exploited in a reaction at the organic substituents of the cluster which produces water as a by-product. Also reported are the synthesis, characterization, and crystal structure of [K-krypt](2)[Ge(9)-(CH=CH-CH(2)NH(2))(2)] involved in the reaction.
متن کاملtechnical and legal parameters for determination of river boundary,( case study haraz river)
چکیده با توسعه شهر نشینی و دخل و تصرف غیر مجاز در حریم رودخانه ها خسارات زیادی به رودخانه و محیط زیست اطراف آن وارده می شود. در حال حاضر بر اساس آئین نامه اصلاح شده بستر و حریم رودخانه ها، حریم کمی رودخانه که بلافاصله پس از بستر قرار می گیرد از 1 تا20 متر از منتهی الیه طرفین بستر رودخانه تعیین، که مقدار دقیق آن در هر بازه از رودخانه مشخص نیست. در کشورهای دیگر روشهای متفاوتی من جمله: درصد ریسک...
15 صفحه اولStandard and modified methods for soil organic carbon determination in agricultural soils
The presented study demonstrates the benefits of using modified vertical photometry methods for rapid, reliable and accurate soil organic carbon determination in agricultural soils. For tests we selected and analysed 25 arable (Ap horizon) topsoil (Cambisol) samples, so that the determined values cover as wide a range as possible. In the proposed method soil organic carbon is determined using 0...
