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. ...
Synthesis and Antitubercular Activity of N3,N5-Diaryl-4-(5-arylisoxazol-3-yl)-1,4-dihydropyridine-
5-Arylisoxazolyl-3-carboxaldehydes were condensed with N-aryl acetoaceta¬mide and ammonium acetate in methanol to give N3,N5-diaryl-4-(5-arylisoxazol-3-yl)-1,4-dihydropyridine-3,5-dicarboxamides. All compounds were screened for their antitubercular activity against Mycobacterium tuberculosis (H37Rv). The results for new synthesized compounds showed a moderate activity in comparison to rifampicin.

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
15 صفحه اولSYNTHESIS AND ANTIMICROBIAL ACTIVITY OF 3-(2’-n-BUTYLBENZOFURAN-3’-YL)-5-ARYL-4, 5-DIHYDRO-1H-PYRAZOLES.
3-(2’-n-butylbenzofuran-3’-yl)-5-aryl-4, 5-dihydro-1H-pyrazoles (4a-4k) have been synthesized. The synthesized products have been assayed for their antimicrobial activity against Gram+ve, Gram-ve bacteria and fungi. All the synthesized products were assigned with IR, 1HNMR, Mass Spectra, TLC, and elemental analysis. Some of the products showed moderate activi...
