3092) Study of Actual vs Predicted Heating Load on Continuous and Periodic Heating

on the relationship between actual vs. perceived difficulties of a text and iranian efl learners reading anxiety

abstract this study examines the relationship between reading anxiety and difficulty of texts as well as the relationship between reading anxiety and students perceived difficulty of the texts. since difficulty is a relative concept, i limited its definition by sticking to the readability formula. we also took students perceived difficulty levels into account. therefore, in the present study, ...

Steady-Periodic Heating of a Cylinder

chemical recycling of polycarbonate waste using conventional heating and microwave assisted method

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...

Continuous Heating of a Hollow Cylinder*

7. The essence of the method of characteristics is the following. Suppose the flow is to be determined in the channel of Fig. 4 and the flow is known up to the line I. Select points A and B on line I. At these points the velocity, the direction of flow, etc., is known. Thus characteristics Ca and Cb can be drawn. Equation (17) used along the two different characteristics gives two equations for...

Analytical and numerical study of Joule heating effects on electrokinetically pumped continuous flow PCR chips.

Joule heating is an inevitable phenomenon for microfluidic chips involving electrokinetic pumping, and it becomes a more important issue when chips are made of polymeric materials because of their low thermal conductivities. Therefore, it is very important to develop methods for evaluating Joule heating effects in microfluidic chips in a relatively easy manner. To this end, two analytical model...
