abstract lexical knowledge of complex english words is an important part of language skills and crucial for fluent language use (nation, 2001). the present study, thus, was an attempt to assess the role of morphological decomposition awareness as a vocabulary learning strategy on learners’ productive and receptive recall and recognition of complex english words. so 90 sophomores (female and ma...
The asymmetric unit of the title basic strontium oxotellurate(IV), Sr5Te4O12(OH)2 {systematic name penta-strontium tetra-kis-[oxotellurate(IV)] di-hydroxide}, comprises three SrII cations (one with site symmetry 2) and two TeIV atoms, as well as seven O atoms. The coordination numbers of the alkaline earth cations to nearby O atoms range from seven (2 ×) to eight, and the TeIV atoms are surroun...
Using the 2dF multi-fibre instrument on the Anglo-Australian Telescope, moderate resolution spectra have been obtained for a large sample of stars on the main sequence and at the turnoff in the unusual globular cluster ω Cen. We investigate the behaviour of CH, CN and SrII line strength indices as a function of overall abundance for the main sequence sample. A number of stars do not follow the ...
Owing to their great potentials in genetic code extension and the development of nucleic acid-based functional nanodevices, DNA duplexes containing HgII-mediated base pairs have been extensively studied during the past 60 years. However, structural basis underlying these base pairs remains poorly understood. Herein, we present five high-resolution crystal structures including one first-time rep...
Phoborhodopsin (pR; also called sensory rhodopsin II, sRII) is a receptor of negative phototaxis of Halobacterium salinarum, and pharaonis phoborhodopsin (ppR; also pharaonis sensory rhodopsin II, psRII) is a corresponding protein of Natronobacterium pharaonis. These receptors contain retinal as a chromophore which bind to a lysine residue via Schiff base. This Schiff base can be cleaved with h...
ژنوم میتوکندریایی شامل ?? ژن کد کنندهء پروتئین است. بسیاری از این ژن ها زنجیرهء انتقال را کد می کنند.ژن 5nd-mt یکی از 13 ژن کد کننده پروتئین است، که زنجیره انتقال الکترون را کد می کند. و جایگاه آن در(i complex)است. ژن 5nd-mt دستورالعمل برای ساختن یک پروتئین به نام nadh دهیدروژناز5 را فراهم می کند. این پروتئین بخشی از یک مجــتمع آنزیم های بزرگ شناخــــته شده با عنوان (i complex)است که در میتوک...
رآیند ردوکس زوج nadh/nad+ که در بیش از 330 آنزیم دی هیدروژناز است در سال های اخیر از موضوعات مهم تحقیقاتی بوده که دارای کاربردهای تجزیه ای و زیستی است. در این کار ما از الکترود کربن شیشه ای اصلاح شده با نانوصفحات گرافن و کمپلکس روتنیوم شامل لیگاند 1و 10 -فنانترولین 5و 6- دی اون به عنوان بستری مناسب برای اکسایش الکتروکاتالیتیکی nadh بکار گرفته شده است. رفتار الکتروشیمی الکترود اصلاح شده به وسیله...
the present study is an experimental case study which investigates the impacts, if any, of skopos on syntactic features of the target text. two test groups each consisting of 10 ma students translated a set of sentences selected from advertising texts in the operative and informative mode. the resulting target texts were then statistically analyzed in terms of the number of words, phrases, si...
