Three techniques that use carrier information from multiple antennas to enhance carrier acquisition and tracking are presented. These techniques in combination with baseband combining are analyzed and simulated for residual and suppressedcarrier modulation. It is shown that the carrier arraying using a single carrier loop technique can acquire and track the carrier even when any single antenna ...
Backgrounds and Aim: One of the effective strategies for targeting chemotherapy in the treatment of cancer is the use of lipid nano-carriers. In this study, an optimal formulation of niosomal drug containing doxorubicin has been developed to better fight cancer cells. Material and Methods: Niosomal vesicles were prepared using phosphatidylcholine (22%), span60 (52/5%), cholesterol (22/5%) and ...
چکیده ندارد.
receptors and proteins are overexpressed in many human cancer cell membranes rather than normal tissues and are considered as the main molecular targets. specific tumor- targeting molecules which have high affinity for these receptors can be valuable tools as carrier molecules for targeted cancer therapy and imaging. pharmacokinetics and bioavailability of diagnostic and therapeutic agents are ...
با توجه به محدود بودن منابع سوختی و لزوم صرفه جویی در مصرف انرژی، استفاده از انرژی خورشیدی به عنوان یک راهکار استراتژیک از اهمیت بسیار زیادی برخوردار است. لذا در این مقاله به کمک استفاده از سیستم ذخیره خورشیدی برای گرمایش ساختمان آزمایشگاهی دانشگاه آزاد اسلامی واحد سمنان سعی در استفاده از انرژی خورشیدی بصورت بهینه شده است در این سیستم ابتدا انرژی مورد نیاز ساختمان مذکور با استفاده از نرم افزار ...
in this paper, an attempt has been made to introduce a new control strategy including plug-in hybrid electric vehicle (phev) and diesel engine generator to control the voltage and frequency of autonomous microgrids. the proposed control strategy has multiple advantages over the recent control methods in microgrids. the proposed method applies the primary and secondary frequency control strategy...
pyrolysis of low density polyethylene (ldpe) by equilibrium fluid catalytic cracking (fcc) was studied in a stirred reactor under different process parameters. in this work, the effect of process parameters such as degradation temperature (420-510°c), catalyst/polymer ratio (0-60%), carrier gas type (h2, n2, ethylene, propylene, ar and he), residence time and agitator speed (0-300 rpm) on the c...
Background and Objective: Use of nano-carriers that contain plant cytotoxic compounds instead of common chemotherapy drugs can reduce many of the challenges in front of this method of cancer therapy. In this study, surfactant nano-systems containing pomegranate peel extract were designed to evaluate its cytotoxic effects on MCF-7 cell line (breast cancer) and investigated its physicochemical pr...
Peat is the best known and the most widely used rhizobial carrier, but unfortunately, it lacks of sufficient sources in Iran. This research aimed at using some inexpensive materials as carrier instead of peat for producing the rhizobial inoculant for alfalfa. For this purpose, the physical and chemical properties of some materials to be used as carriers were determined and the viability of Sino...
