Electrical discharge machining process, is one of the most widely used methods for machining, the electrically conductive parts. In this way the tool is not in contact with the workpiece and the hardness of workpiece does not affect the machining speed. In Electrical Discharge Machining process, selection of the correct machining parameters are effective in final cost and the quality of the pro...

the aim of this study was to investigate the effect of ultrasound and drying pretreatments on apparent density as well as modeling apparent density during deep-fat frying of potato slices. ultrasound pretreatment was performed at 28 and 40 khz for 15 min and drying pretreatment were conducted at 80°c for 8 and 15 min. then, the frying process was done at 150, 170 and 190°c for 60, 120, 180 and ...

In 2018, nuclear energy generated 55% of United States’ and one third the world’s carbon free electricity, making a key tool in efforts to mitigate climate change before 2050. However, current technology, light water reactors (LWRs), is limited 300°C, so it cannot be used decarbonize industrial process heat which accounts for 12% US greenhouse gas emissions. High temperature (HTGRs) can meet hi...
