In this paper, a new numerical control system(CNC) based on ARM9 and STC12C5410 is studied. The ARM9 core microprocessor, Samsung S3C2440A microprocessor, is the main operation core. It treats the flowing tasks: response to keyboard inputting, display contents on LCD, interpretive the NC codes, output crude interpolations and so on. The secondary CPU, STC12C5410, as the assisting microprocessor is only to realize fine interpolation. The system can be connected an 8-inches display in order to display more information and it has an interface to a four-axis hand wheel. It has a communication interface and can receive CNC codes form other computer. The system can drive four step-servo motors or servo-actuators and realize turning, milling, grinding and combination machining. That is that the system is a multifunction system. © (2012) Trans Tech Publications, Switzerland. Source

Food and Function

Carbohydrate consumption during exercise can improve performance and delay the onset of fatigue. The purpose of this study was to develop a novel sports drink powder, Jxdrink, containing the high molecular weight polysaccharide Jxsac. Animal experiments including digestion and exhaustive swimming experiments were conducted to observe the physiological effects of this beverage. Human experiments involved the participation of 10 healthy male athletes completing a 180 km road cycling test. The osmolality of Jxdrink was 170-175 mosmol kg-1, lower than that of human blood. Jxdrink was found to prolong the exhaustive swimming time in test animals. Moreover, Jxdrink had a relatively high glycemic index that maintained blood glucose levels during human cycling experiments. Thus, Jxdrink was found to effectively delay the onset of fatigue in both human and animal experiments. © 2014 the Partner Organisations. Source
