Optical resonant microcavities with ultra high quality factors are widely used for biosensing. Until now, the primary method of detection has been based upon tracking the resonant wavelength shift as a function of biodetection events. One of the sources of noise in all resonant-wavelength shift measurements is the noise due to intensity fluctuations of the laser source. An alternative approach ...
A new detection mechanism has been developed for low molecular weight substrate binding to heme proteins based on resonance localized surface plasmon spectroscopy. Cytochrome P450 has strong electronic transitions in the visible wavelength region. Upon binding of a substrate molecule (e.g., camphor), the absorption band of cytochrome P450 shifts to shorter wavelength. The event of camphor bindi...
In this paper we present a sensing method using nano-porous silicon microcavity sensor, which was developed in order to obtain simultaneous determination of two volatile substances with different solvent concentrations as well as very low pesticide concentration in water. The temperature of the solution and the velocity of the air stream flowing through the solution have been used to control th...
امروزه ، استراتژی ها و روشهای مختلفی توسط مترجمان در زمینه ترجمه متون به کار گرفته می شود. یکی از این روشهای رایج، استفاده از شیفت ها است. مطالعه ی پیش رو کاربرد استراتژی شیفت ها در ترجمه بروشورهای تبلیغاتی مربوط به محصولات مراقبت شخصی از زبان انگلیسی به فارسی را بر اساس مدل کتفورد (1965) مورد بررسی قرار داده است. هدف این مطالعه بررسی میزان استفاده از این استراتژی از طریق مقایسه متون زبان مبدا ...
toury (1978:200) believes that translation is a kind of activity which inevitably involves at least two languages and two cultural traditions. being polite while asking for something takes place differently in different cultures and languages, therefore various strategies may be applied for making requests and also translation of them in order not to disturb or threaten the face or better to sa...
