A survey of the smoking habits amongst Medical students was conducted in January July, 1981. Of 2204 registered students, 1363 (62%) returned the self administered questionnaires. At the time of survey there were 191 smokers (M.188, F-3), 27 ex.smokers (M-26 F-1) and 1145 Non-smokers (M668, F477). The average age at start of smoking was 17 years amongst smokers and 18 year amongst exsmokers. Th...
The ERD2 gene, which encodes the yeast HDEL (His-Asp-Glu-Leu) receptor, is essential for growth (Semenza, J. C., K. G. Hardwick, N. Dean, and H. R. B. Pelham. 1990. Cell. 61:1349-1357; Lewis, M. J., D. J. Sweet, and H. R. B. Pelham. 1990. Cell. 61:1359-1363). SED5, when present in multiple copies, enables cells to grow in the absence of Erd2p. Sequence analysis of SED5 reveals no significant ho...

We study multivariable spectral multipliers F (L1, L2) acting on Cartesian product of ambient spaces of two self-adjoint operators L1 and L2. We prove that if F satisfies Hörmander type differentiability condition then the operator F (L1, L2) is of Calderón-Zygmund type. We apply obtained results to the analysis of quasielliptic operators acting on product of some fractal spaces. The existence ...
This paper raises the need for quantitative accessibility measurement and proposes three different application scenarios where quantitative accessibility metrics are useful: Quality Assurance within Web Engineering, Information Retrieval and accessibility monitoring. We propose a quantitative metric which is automatically calculated from reports of automatic evaluation tools. In order to prove ...
Online banking and e-commerce applications have good protection against attacks directed direct towards their computer systems. This, the attacker has considered and instead use " social engineering " attacks, such as phishing to gain access to the information inside [1] [15] [20]. Phishing is a growing problem that many different companies are trying to develop a working protection against. Th...
باتوجه به رشد نظامهای اقتصادی و پیچیده تر شدن روابط بین متغیرها، لزوم بررسی و تصمیم گیریهای اقتصادی براساس روشهای پیشرفته ریاضی بیشتر احساس میشود. میتوان گفت برای سیستمهای ساده مهمترین مسئله شناخت روابط بین متغیرهای آن است . اما با پیچیده ترشدن سیستمها علاوه برشناخت روابط بین متغیرها، چگونگی کنترل و هدایت آنها نیزاهمیت پیدامیکند بطوریکه دربعضی از موارد داشتن روشی برای بررسی و سیاستگذاری بیش از ...
