· 1. Introduction. The Romanian 1 economist Georgescu-Roegen is best known for pointing out somewhat controversially—but correctly—that high-quality low-entropy resources such as oil and gas and metals are converted by the economy into high-entropy wastes. He went on to assert a fourth law of thermodynamics namely that mass like energy becomes increasingly unavailable and that
· There are two types of boards. One is the print circuit board (PCB) and the other is the print wiring board (PWB) that copper pattern exists inside of board. The copper smelter in Japan is compared with the recycling process of PCB using heat treatment. The evaluation of copper nickel and tantalum recovery process from PCB is considered as follows.
Energy consumption is very low. The output is linear and temperature-stable. The sensor IC frequency response is flat up to approximately 25 kHz. A Hall-effect sensor IC is more efficient and effective than inductive or optoelectronic sensors and at a lower cost. top Sensitive Circuits for Rugged Service
