Some drugs have low bioavailability due to their poor aqueous solubility and/or slowdissolution rate in biological fluids. Stiripentol (STP) is a novel anticonvulsant drug that isstructurally unrelated to the currently available antiepileptics. It has poor aqueous solubilityand its solubility has to be enhanced accordingly. Polyethyleneglycol 6000 (PEG-6000) iscommonly utilized as a hydrophilic...
این آزمایش (سال 1386) برای ارزیابی اثر غلظتهای مختلف ایندول بوتیریک اسید (0، 2000 ، 4000 و 6000 میلی گرم در لیتر)، نفتالین استیک اسید (0، 1000 ،2000 و 3000 میلی گرم در لیتر) و برهمکنش آنها بر ریشه زایی قلمههای نیمه خشبی کیوی فروت (Actinidia deliciosa) رقم هایوارد به صورت فاکتوریل در قالب طرح بلوکهای کامل تصادفی در 3 تکرار و 16تیمار در گلخانه دانشگاه آزاد اسلامی واحد رشت انجام شد. قلمه ها در ...
The EFAR project has measured peculiar motions in two distant volumes of the universe using Fundamental Plane (FP) distances for 85 clusters with 6000 km s −1 <cz<15000 km s −1. The scatter in distance about the FP is observed to be 20% per galaxy for EFAR sample, resulting in peculiar velocities with a median precision of 1075 km s −1 for the 50 clusters with 3 or more galaxies. We find that t...
In December 1998, a 488 node IBM RS/6000 SP sorted a terabyte of data (10 billion 100 byte records) in 17 minutes, 37 seconds. This is more than 2.5 times faster than the previous record for a problem of this magnitude. The SPsort program itself was custom-designed for this benchmark, but the cluster, its interconnection hardware, disk subsystem, operating system, file system, communication lib...
Near-infrared (NIR) spectra of carbonates have proved important in many disciplines including planetary exploration. Classically bands in the 4000-6000 cm(-1) (2.5-1.67 μm) region are assigned to [CO3(2-)] internal mode combinations and overtones. However band assignments remain equivocal. This study examines three prominent bands ((ca 4505 cm(-1) (2.219 μm), 4900 cm(-1) (2.041 μm) and 5145 cm(...
We describe a high-performance, compact optical frequency standard based on microfabricated Rb vapor cell and low-noise, external cavity diode laser operating the two-photon transition at 778 nm. The achieves an instability of 1.8x10$^{-13}$/$\sqrt{\tau}$ for times less than 100 s flicker noise floor 1x10$^{-14}$ out to 6000 s. At long integration times, is limited by variations in probe power ...

The performance of adaptive systems that consist of microscale on-chip elements [microelectromechanical mirror (mu-mirror) arrays and a VLSI stochastic gradient descent microelectronic control system] is analyzed. The mu-mirror arrays with 5 x 5 and 6 x 6 actuators were driven with a control system composed of two mixed-mode VLSI chips implementing model-free beam-quality metric optimization by...
