نمایشنامه به پیروی از ماهیت دوگانه اش، کارکردی دوگانه به خود می گیرد، بدین معنا که در هر دو نظام ادبی و تئاتری می تواند کارکردی مختص به خود یابد. هدف از انجام این پژوهش یافتن تفاوت ها میان ترجمه صفحه و ترجمه صحنه است.. پرسش مطرح شده عبارتست از: بر اساس مدل ارائه شده توسط لدوسر (1995)، تفاوت های ترجمه صفحه و ترجمه صحنه در چیست؟ یافته های این پژوهش حاکی از آن است که ترجمه صفحه به نمایشنامه ا...
Sonochemical preparation of supported hydrodesulfurization catalysts.
Sonochemical preparation of Co and Ni promoted MoS(2) supported on alumina was achieved by high-intensity ultrasonic irradiation of isodurene solutions containing molybdenum carbonyl, dicobalt octacarbonyl, elemental sulfur, and Al(2)O(3) or Ni-Al(2)O(3) under Ar flow. The sonochemically prepared catalysts were characterized by elemental analysis, XPS, SEM, TEM, and XEDS, and hydrodesulfurizati...
متن کاملSolid State Synthesis and Characterization of Model Hydrodesulfurization Catalysts
Solid-state reactions of elemental sulfur with metallic cobalt and molybdenum powders were used to synthesize model catalysts for hydrodesulfurization (HDS). The resulting materials had a general stoichiometry of CozlMo,-,S2 with x between 0.025 and 0.3. The solid phases formed during synthesis and after exposure to typical HDS reaction conditions were identified by X-ray diffraction and select...
