AIM To highlight the rising trend in hospital presentation of foreign bodies retained in the rectum over a 5-year period. METHODS Retrospective review of the cases of retained rectal foreign bodies between 2008 and 2012 was performed. Patients' clinical data and yearly case presentation with data relating to hospital episodes were collected. Data analysis was by SPSS Inc. Chicago, IL, United ...

here, we report analysis of in vitro and in vivo drug release from an in situ formulation consisting of triamcinolone acetonide (tr) and poly(d,l-lactide-co-glycolide) (plga) and the additives glycofurol and hydroxyapatite nanoparticles (ha). we found that these additives enhanced drug release rate. we used the taguchi method to predict optimum formulation variables to minimise the initial burs...
On the basis of existing dust collector structure, this study designed a fan-shaped new structure microporous membrane filter plate (NSMMFP). The pressure distribution law NSMMFP can be obtained by measuring wall surface peak under different injection pressures. powder attachment experiment was carried out to explore influence moisture content on stripping rate (DSR), and high-speed camera used...
هدف از انجام این پروژه آشکارسازی trend باند آلفا سیگنال الکتروانسفالوگرام با استفاده از پردازش تصویر اسپکتروگرام آن است. به عبارت دیگر تغییرات ایجاد شده در طیف باند آلفا که در طول زمان و به دلیل یک پدیده¬ی فیزیولوژیکی یا شناختی رخ می¬دهد را بتوان با استفاده از پردازش اسپکتروگرام آشکار کرد. در این پروژه خستگی ذهنی به عنوان یک پدیده¬ی شناختی برای ایجاد تغییرات در باند آلفا مورد مطالعه قرار گرفت. ...
asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...
We present an analysis of far-infrared dust emission from diffuse cirrus clouds. This study is based on serendipitous observations at 160μm at high galactic latitude with the Multiband Imaging Photometer (MIPS) onboard the Spitzer Space Telescope by the Spitzer Infrared Nearby Galaxies Survey (SINGS). These observations are complemented with IRIS data at 100 and 60μm and constitute one of the m...
The increasing trend of opencast coal mining in India tends to release huge amounts of dust. But there is no well-defined method of estimating dust emission due to different coal mining activities. This paper examines the sources of dust emission due to coal mining activities, and focuses on the quantification of dust emission with the development and use of emission factors. Because of their s...
