This paper presents an experimental study of the heating value of medical waste using an input-output method. The study was carried out at the Oncological Hospital in Bydgoszcz, Poland, over a period of three months. The installation for thermal treatment consisted of a loading unit, a combustion chamber, and a discharge chamber (thermoreactor). The medical waste constituted the primary fuel, a...
The gross calorific value (GCV) or heating value of a sample of fuel is one of the important properties which defines the energy of the fuel. Many researchers have proposed empirical formulas for estimating GCV value of coal. There are some known methods like Bomb Calorimeter for determining the GCV in the laboratory. But these methods are cumbersome, costly and time consuming. In this paper, m...

BACKGROUND Microwave heating is one of the most attractive cooking methods for food preparation, commonly employed in households and especially in restaurants for its high speed and convenience. The chemical constituents of oils that degrade during microwave heating do so at rates that vary with heating temperature and time in a similar manner to other type of processing methods. The rate of qu...
Accurately and efficiently predicting the LHV of MSW is vital for designing operating a waste-to-energy plant. However, previous prediction models possess limited geographical applicability. In this paper, we employ multiple linear regression artificial neural network (ANN) techniques to predict LHV. These data-driven utilize 151 globally distributed datasets identified during systematic litera...
لوکمی از جمله بیماری هایی است که در کودکان شیوع بیشتری دارد، اما ریسک فاکتورهای اصلی این بیماری همچنان ناشناخته باقی مانده اند، این مطالعه گذشته نگر به نقش میدان های الکترومغناطیسی در بروز لوکمی کودکان و تعیین نقش آلفا آمیلاز به عنوان بیومارکر تعیین کننده سابقه مواجهه با این میدان ها پرداخته است. جمعیت مورد مطالعه شامل 100 نفر کودک سالم کمتر از 12 سال و 22 نفر کودک کمتر از 12 سال با تشخیص قطعی ...
the mode of heat and mass transfer during baking of bakery products is an important factor determining the quality of the final product. the heating rate could alter the starch properties during gelatinization and affect the quality of products after baking and during aging. sangak is a kind of iranian flat bread baked on the hot pebble gravels. the aim of this study was to evaluate the impacts...
induction heating is widely used in metal industry for melting or heating thin slabs in a continuous casting plant. the wide application is based on good efficiency, high production rate and non-polluting conditions. for designing a parallel resonant induction heating system, calculating the capacitance for the resonant circuit is important, because its value affects resonance frequency, output...
