second language acquisition of telicity and aspect by persian learners of english
این تحقیق از دو قسمت اصلی تشکیل شده است: در قسمت اول فراگیری ختمیت به ویژه درک و تولید اینگونه جملات توسط فراگیران ایرانی زبان انگلیسی مورد بررسی قرار گرفته است. قضاوت تعدادی انگلیسی زبان بر روی این جملات نیز هدفی دیگر بود که در این رساله بررسی شده است. از موضوعات دیگر تفاوت بین نشانه های ختمیت در زبان انگلیسی و فارسی و تاثیر زبان اول فراگیران در درک و تولید اینگونه جملات است. در قسمت دوم استفا...
15 صفحه اولUV Spectrophotometric Simultaneous Determination of Paracetamol and Ibuprofen in Combined Tablets by Derivative and Wavelet Transforms
The application of first-order derivative and wavelet transforms to UV spectra and ratio spectra was proposed for the simultaneous determination of ibuprofen and paracetamol in their combined tablets. A new hybrid approach on the combined use of first-order derivative and wavelet transforms to spectra was also discussed. In this application, DWT (sym6 and haar), CWT (mexh), and FWT were optimiz...
متن کاملRP-HPLC Method for Simultaneous Estimation of Paracetamol and Ibuprofen in Tablets
A simple, selective, accurate high Performance Liquid Chromatographic (HPLC) method was developed and validated for the analysis of Paracetamol and Ibuprofen. Chromatographic separation achieved isocratically on a C18 column [Use Inertsil C18, 5μ , 150 mm x 4.6 mm] utilizing a mobile phase of acetonitrile/phosphate buffer (60:40, v/v, pH 7.0) at a flow rate of 0.8 ml/min with UV detection at 26...

AIM AND BACKGROUND A stability-indicating LC method was developed for the simultaneous determination of Ibuprofen and Famotidine in pharmaceutical dosage forms. MATERIALS AND METHODS The chromatographic separation was achieved on Acquity UPLC BEH C-18,50 mm × 2.1 mm and 1.7 μm column with gradient elution. The mobile phase A contains a mixture of 50 mM sodium acetate buffer (pH 5.5): methanol...
متن کاملDetermination of Metoprolol in Pharmaceutical Preparations by Zero-, First-, Second- and Third-order Derivative Spectrophotometric Method
In this study, zero-, first-, secondand third-order derivative spectrophotometry methods were developed for the determination of metoprolol in pharmaceutical preparations. In zero order spectrophotometry, absorbance values were measured at 276 nm in zero order spectra of solution of metoprolol in methanol in the range of 240-310 nm. In first derivative spectrophotometry, absorbance values were ...
