the environmental scanning electron microscopy (esem) is a new development in the field of electron microscopy. in this study esem has been used to study the structure of veal semimembranosus muscle. four treatments, raw (control), conventional heating, domestic and industrial microwave heating, were observed using esem. the temperature used in conventional heating was 163 0c. frequency app...
پلی کربنات یکی از پلاستیکهای مهمی است که به صورت گسترده در تولید لوحهای فشرده، قطعات رایانه، مواد ساختمانی و غیره مورد استفاده قرار می گیرد. این پلیمر بصورت عمده از تراکم مونومر بیس فنولa (bpa) و کربنیل کلرید یا دی متیل کربنات ها بدست می آید. در سالهای اخیر بازیافت شیمیایی پلی کربنات بیشتر مورد توجه بوده است. بازیافت شیمیایی پلی کربنات برای بدست آوردن مواد اولیه آن با روشهای متفاوتی مانند تجزی...
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
background and objectives: red colored fruits such as cornelian cherry (cornus mas l) are recognized as being healthy. the color of these fruits is an important sensory property in assessment of product quality therefore, minimizing the loss of color in the process is very important. materials and methods: in this study, comparison of the color, turbidity, degradation rate of anthocyanin, and r...

Utilization of combined heat and power (CHP) systems that simultaneously fulfill the electrical and heating energy needs is considered as an effective strategy for management of energy demand and consumption. Overall operational efficiency in excess of 70% is made possible, when these systems are utilized, and it is expected that needs for both the demand and supply sides are met even under ...
We present the design and simulation of a single-walled carbon nanotube(SWCNT)-based field-effect transistor (FET) using Silvaco TCAD. In this paper, theself-heating effect modeling of the CNT MOSFET structure is performed and comparedwith conventional MOSFET structure having same channel length. The numericalresults are presented to show the self-heating effect on the I...
The present work evaluates the anthocyanin degradation in blueberry pulp after thermal treatment using ohmic and conventional heating. The ohmic heating technology was studied using a rotatable central composite design, and the variables studied were voltage and solids content. The anthocyanin content of the samples was determined using HPLC. The results show that degradation increased with bot...
