Photoswitchable interlocked thiodiglycolamide as a cocatalyst of a chalcogeno-Baylis–Hillman reaction

Photoswitchable interlocked thiodiglycolamide as a cocatalyst of a chalcogeno-Baylis-Hillman reaction.

En route to a photoswitchable interlocked catalyst we have proved the ability of thiodiglycolamide to act as a template in the formation of hydrogen-bonded [2]rotaxanes. X-ray diffraction studies reveal the shielding of the sulfide atom by the macrocycle. A series of molecular shuttles are described as having an isomerizable fumaramide and thiodiglycolamide binding sites for controlling the rel...

translating allusive devices:a survey of a portrait of the artist as a young man by james joyce

تلمیح یکی از عناصری است که تقریباً در همه ی متون ادبی یافت و باعث ایجاد شکاف های فرهنگی می شود. در این تحقیق به عنوان شکلی از بینامتنیت در ترجمه مورد توجه قرار می گیرد. تلاش شده است تا راهکارهای مترجمان برای ترجمه چهار نوع اسامی خاص و عبارات کلیدی تلمیحی (مذهبی، سیاسی، تاریخی و اسطوره ای) موجود در رمانِ چهره مرد هنرمند در جوانی به فارسی بررسی شود. این تحقیق مقایسه ای بر اساس راهکارهای ترجمه تلمیح...

the effectiveness of strategy-based instruction in teaching english as a second or foreign language: a meta-analysis of experimental studies

a large number of single research studies on the effects of strategy-based instruction (sbi) in teaching english as a foreign or second language has been conducted so far. however, the lack of a comprehensive meta-analysis targeting the effectiveness of english language sbi is observed. moreover, the findings of experimental studies regarding the context of the english language, proficiency lev...

the significance of conjunction as a cohesive device in teaching writing

the research questions were as follows: 1. is there any relationship between the students concious awareness of the form and implications of the conjuncations and their improvement in using appropriate conjunctions? 2. does students knowledge of the from and the implications of the conjunctions help them to produce more coherent writings. 3. does a comparison between english conjunctions and th...
