this research concentrates on the lithostratigraphy, biostratigraphy, microfacies and sedimentary environment of the asmari and gachsaran formations at southwest firuzabad. the thickness of the studied section in all 608.95 meters that 220.8 meters belong to the asmari formation and 387.95 meters belong to the gachsaran formation (champe and mol members). in the study area, the asmari formation...
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. ...
literature has always been proportional to the taste of humanity and played a prominent role in revolutions and social movements to achieve independence and freedom during history. resistance literature as a branch of literature, has made a roaring literature that there is no way of stop and hopelessness to it, and has defended societies by putting aside repressive force, it has acted like a de...
this study investigated how group formation method, namely student-selected vs. teacher-assigned, influences the results of the community model of teaching creative writing; i.e., group dynamics and group outcome (the quality of performance). the study adopted an experimental comparison group and microgenetic research design to observe the change process over a relatively short period of time. ...
dans le monde où l’homme est l’élément le plus important de la vie, la formation de nouvelles générations a une importance particulière. en rédigeant emile, jean jacques rousseau, exerce une influence extraordinaire sur la vie humaine et mène à réfléchir sur la question de l’éducation en tant qu’un art. ce penseur du xviiie siècle, grâce à son élève imaginaire, emile, présente son idéal pédagog...
در این پژوهش به منظور درک سن و محیط رسوبی سازند آسماری در برش کوه شجبیل، شمال غرب یاسوج به ضخامت 375 متر 171 نمونه برداشت گردیده است. سازند آسماری در برش مورد مطالعه با معیارهای سنگ شناختی به سه واحد مشخص تفکیک شده است. این واحد ها با داشتن شمای آهک های مسیو، ضخیم، متوسط و نازک لایه، آهک های نازک لایه ی مارنی و بعضاً مارن مشخص می گردد. در این برش تعداد 18 جنس و 29 گونه از فرامینیفرهای بنتیک شنا...
in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...
