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. ...

15 صفحه اولروسیه و دورنمای گاز در آسیای مرکزی و قفقاز فرصتهاو تهدیدهای ایران russia and outlook of gas in central asia and caucasus opprtunities and threats of iran
بر اساس قانون عرضه و تقاضا افزایش عرضه هر کالا به کاهش قیمت آن منجر میشود گاز طبیعی هم بعنوان یک کالای مهم و پر مصرف از این قاعده مستثنی نیست و فروش بی رویه گاز از طرف کشورهای دارنده آن در آسیای مرکزی و قفقاز میتواند منافع ملی ایران و روسیه را تحت الشعاع قرار دهد . این رساله فرصت ها و تهدید های ایران را در این زمینه مورد مطالعه قرار میدهد.
15 صفحه اولDirect measurements of intervessel pit membrane hydraulic resistance in two angiosperm tree species.
The hydraulic resistance of pit membranes was measured directly in earlywood vessels of Fraxinus americana and Ulmus americana. The area-specific resistance of pit membranes (r(mem)) was higher than modeled or measured values obtained previously for hardwood species, with r(mem) of 5.24 × 10(3) MPa·s·m(-1) for Fraxinus and 2.56 × 10(3) MPa·s·m(-1) for Ulmus. The calculated resistance of pit can...
متن کاملResponse of three eastern tree species to supplemental UV-B radiation: leaf chemistry and gas exchange
Quantitative changes in foliar chemistry in response to UV-B radiation are frequently reported but less is known about the qualitative changes in putative UV-screening compounds. It has also not been conclusively shown whether qualitative differences in screening compounds or differences in localization patterns influence the sensitivity of plants to damage from UV-B radiation and there is some...
