از سالهای پایانی دهۀ 60 موج تغییر فرهنگی و اجتماعی در ایران به راه افتاد و بهتدریج کل حیات اجتماعی را درنوردید. این تغییر عمدتاً به سیاستهای اقتصادی- اجتماعی پس از پایان جنگ و از جمله برنامۀ تعدیل ساختاری اقتصاد نسبت داده شده است. این مقاله با هدف روایت نمونهای از مواجهه هنرمندان با این روند، فیلم سگکشی بهرام بیضایی را بازخوانی میکند؛ فیلمی که سناریوی آن درست در آغاز دهۀ 70 نوشته شد، اما س...
Testing for software security is a lengthy, complex and costly process. Currently, security testing is done using penetration analysis and formal verification of security kernels. These methods are not complete and are difficult to use. Hence it is essential to focus testing effort in areas that have a greater number of security vulnerabilities to develop secure software as well as meet budget ...
Watanabe M, Bland C, Fox K, Poole-Wilson PA, Rees RS et al. Dimensional accuracy of magnetic resonance in studies of the heart. Lancet 1985;1: 1360–1362. 32. Fieno DS, Kim RJ, Chen EL, Lomasney JW, Klocke FJ, Judd RM. Contrast-enhanced magnetic resonance imaging of myocardium at risk: distinction between reversible and irreversible injury throughout infarct healing. J Am Coll Cardiol 2000;36: 1...
We report results from a survey of high velocity clouds and the Magellanic Stream for faint, diffuse optical recombination emission lines. We detect Hα emission with surface brightness from 41 to 1680 mR from HVCs, and from < 40 to 1360 mR in the MS. A simple model for the photoionizing radiation emergent from the Galaxy, normalized to the HVCs A and M with known distances, predicts distances f...
H2Av is a versatile histone variant that plays both positive and negative roles in transcription, DNA repair, and chromatin structure in Drosophila. H2Av, and its broader homolog H2A.Z, tend to be enriched toward 5' ends of genes, and exist in both euchromatin and heterochromatin. Its organization around euchromatin genes and other features have been described in many eukaryotic model organisms...
We determined yearly change in prevalence and risk factors for amebic colitis caused by intestinal invasive amebiasis among persons who underwent endoscopy and assessed differences between HIV-positive and HIV-negative persons in Japan. A total of 10,930 patients were selected for analysis, of whom 54 had amebic colitis. Prevalence was in 2009 (0.88%, 12/1360) compared with 2003 (0.16%, 3/1904)...
The aim of this study was to determine the caries prevalence in urban and suburban Albanian schools. A large sample (n= 2617) of subjects, aged 7-15, was examined by a clinical observation without radiograms. The sample comprised 1257 males and 1360 females. For each subject an anamnestic questionnaire about feeding, fluoride, dentist attendance and familiar informations was obtained. Gender an...
This article describes the development of a test for measuring the intelligibility of speech in noise for the Spanish language, similar to the test developed by Kalikow, Stevens, and Elliot (Journal of the Acoustical Society of America, 5, 1337-1360, 1977) for the English language. The test consists of six forms, each comprising 25 high-predictability (HP) sentences and 25 low-predictability (L...
A theory for non-linear rheology of molten polymer layers between solid surfaces in the Rouse regime is discussed. It is shown that the effect of finite extensibility of polymer chains leads to the characteristic 1/3 power law for the shear stress vs. shear velocity in the regime of high velocities. It is also shown that bridging polymer fragments connecting the two surfaces play an important r...
دهۀ 1980 دهه انتظارات بزرگ بود. ضربات تخریب کنندۀ دهۀ 13970 را سپری کرده بودیم رکدها هر چند دردناک بود ولی باعث ایجاد زمینۀ رونق غیر تورمی و رشد اقتصادی شد متأسفانه فرصت از دست داده شد و اینک در دهه 1990 دولت ها وارث اقتصادی ملی می باشند که به مراتب پایین تر از ظرفیت بالقوه آنها عمل می کند و شاهد سیاست های نا هماهنگی هستند که مبادلات جهانی را دستخوش هرج و مرج و بی نظمی می سازد.
