Market penetration studies indicate that in the absence of tax credits, large reductions in the costs of active solar hot water/space heating systems will be necessary. A number of potential means for equipment and labor cos‘t reductions are pres'ented. The use of drainback systems with'polybutylene pipe and a variety of low-cost collector concepts is discussed-. The pros and cons of the variou...

An easy and cheap fabrication method for intricate polydimethylsiloxane microfluidic devices is presented. The acrylonitrile butadiene styrene scaffold-removal method uses cheap, off-the-shelf materials and equipment for the fabrication of intricate microfluidic devices. The versatility of the method is proven by the fabrication of 3D multilayer, ship-in-a-bottle, selective heating, sensing, an...

Background & Aims of the Study: Many working conditions-related stress factors that can produce injuries and illnesses are important in hospital environments. So, the health and safety of nurses and patients from workplace-induced injuries and illnesses is important. In this study, we have assessed the safety condition of one of the teaching hospitals in Kermanshah (2015). ...

“Heat Flux” instruments use an alternative method where both pans are heated from a single heating source in the DSC cell walls. The temperature difference between the two pans is monitored using thermocouples positioned under the sample and reference pans. The actual heat flow into or out of the sample pan is calculated from the measured temperature difference. This approach is that used by TA...

Induction heating equipment is a source of strong and nonhomogeneous magnetic fields, which can exceed occupational reference levels. We investigated a case of an induction tempering tunnel furnace. Measurements of the emitted magnetic flux density (B) were performed during its operation and used to validate a numerical model of the furnace. This model was used to compute the values of B and th...

In the past few years, Rapid Thermal Processes (RTP) have gained acceptance as mainstream technology for semi-conductors manufacturing. These processes are characterized by a single wafer processing with a very fast ramp heating of the silicon wafer (up to 200C/sec). The single wafer approach allows for faster wafer processing and better control of process parameters on the wafer. As feature si...
