در دهه های اخیر فرآیندهای غشایی به مانند تراوش تبخیری و نفوذ بخار به منظور آبزدایی محلولهای آلی و همچنین جداسازی ترکیبات فرار آلی جایگاه خاصی را در بین عملیات جداسازی در صنایع مختلف به خود تخصیص داده اند. علاوه بر این، همراه کردن واکنش های تعادلی به مانند استری شدن با فرآیند جداسازی غشایی نفوذ بخار و تراوش تبخیری موجب دسترسی به درصد تبدیل بالاتر میشود. در این تحقیق فرآیند استریفیکاسیون ایزوپروپ...
Biodiesel production through chemical interesterification of triglycerides requires an excess methyl acetate that must be recovered once the reaction is finished and catalyst neutralized. The present study concerns with purification by pervaporation. PERVAP 2201 was chosen as pervaporation membrane due to its high hydrophilic character makes it suitable for elimination water in acetate. Runs we...
AM-2201 is a synthetic cannabinoid that acts as a potent agonist at cannabinoid receptors and its abuse has increased. However, there are no reports of the inhibitory effect of AM-2201 on human cytochrome P450 (CYP) or uridine 5'-diphospho-glucuronosyltransferase (UGT) enzymes. We evaluated the inhibitory effect of AM-2201 on the activities of eight major human CYPs (1A2, 2A6, 2B6, 2C8, 2C9, 2C...

We report the discovery of the most distant known AGN, the radio galaxy TN J0924−2201 at z = 5.19. The radio source was selected from a new sample of ultra–steep spectrum (USS) sources, has an extreme radio spectral index α 365MHz = −1.63, and is identified at near–IR wavelengths with a very faint, K = 21.3± 0.3 object. Spectroscopic observations show a single emission line at λ ∼ 7530 Å which ...
Core Based Trees (CBT) Multicast Routing Architecture Status of this Memo This memo defines an Experimental Protocol for the Internet community. This memo does not specify an Internet standard of any kind. Discussion and suggestions for improvement are requested. Distribution of this memo is unlimited. Abstract CBT is a multicast routing architecture that builds a single delivery tree per group...
Microstructures of Tl 2 Ba 2 CuO 6 (Tl-2201) thin ®lms with dierent doping levels grown on SrTiO 3 substrates were studied by transmission electron microscopy. It is found that Tl-2201 ®lms are epitaxial single phase over large area. A new three-dimensional modulation structure was observed for the heavily overdoped ®lms. With decrease of doping level from heavily overdoped to optimally doped,...
We have searched for HI 21cm absorption toward the two brightest radio AGN at high redshift, J0924–2201 at z = 5.20, and J0913+5919 at z = 5.11, using the Giant Meter Wave Radio Telescope (GMRT). These data set a 3σ upper limit to absorption of < 30% at 40 km s resolution for the 30 mJy source J0913+5919, and < 3% for the 0.55 Jy source J0924–2201 at 20 km s resolution. For J0924–2201, limits t...
