[ 1 ] - ارزیابی سهم فناوری در ایجاد ارزش‌افزودۀ بخش صنعت (مطالعۀ موردی: زنجیرۀ ارزش صنایع شیمیایی استان فارس)
این مطالعه با هدف سنجش سهم فناوری در زنجیرة ارزش صنایع شیمیایی و تأثیر آن بر ارزش‌افزودة این زنجیره انجام گرفته است. شبکة ارزش صنایع شیمیایی استان شامل 581 واحد تولیدی فعال است که در پنج مرحله و 21 گروه تولیدی ترسیم شد و داده‌ها با استفاده از 141 پرسشنامه به روش گلوله‌برفی گردآوری شدند. سهم فناوری و ارزش‌افزوده در هر مرحله و گروه براساس مدل فرناندز تعیین و سهم فناوری در ایجاد ارزش‌افزودة هر گرو...
[ 2 ] - Experimental and Theoretical Investigation of Drying of Green Peas in a Fluidized Bed Dryer of Inert Particles Assisted by Infrared Heat Source
Drying of green peas in a Fluidized Bed Dryer (FBD) with inert particle, heated by combined sources of hot air and InfraRed (IR) radiation, has been experimentally and theoretically studied. For this purpose, an experimental set up was constructed. This setup was composed of a cylindrical bed dryer containing some inert particles which are fluidized by hot air. Some infrar...
[ 3 ] - Physical Properties of Green Pea in an Inert Medium FBD Dryer Assisted by IR Heating
The drying behavior of green peas is investigated in a pilot scaled Fluidized Bed Dryer (FBD) with inert particles assisted by an Infra Red (IR) heat source. The variation of shrinkage and moisture diffusivity with temperature and moisture content were investigated. The experimental drying curves were adjusted to the diffusion model of Fick’s law for spherical particles. The result was that...
[ 4 ] - Enhancement of Pseudomonas Aeruginosa Growth and Rhamnolipid Production Using Iron-Silica Nanoparticles in Low-Cost Medium
The application of iron-silica (Fe-Si) nanoparticles for the enhancement of the Pseudomonas aeruginosa growth and rhamnolipid production in molasses medium was studied. The experiments were designed based on the response surface method (RSM) to optimize growth and rhamnolipid production. The concentration of nanoparticles and the time required to add nanoparticles to culture medium were conside...
