Finally,through the empirical analysis of labor-capital investment in Henan's agricultural production,combined with the principles of isoquant curve model,this paper determines the labor required for a certain scale of investment in agricultural production,and concludes that the fixed assets investment in Henan's agricultural production is not fully utilized,and too much labor is transferred. And this paper makes the corresponding policy recommendations for Henan's macroeconomic development.展开更多

The purpose was to determine whether pressure measured behind the knee correlated with genital pressure, thereby showing that behind-the-knee pressure measurements could be extrapolated to genital pressures recorded under clinical in-use conditions. Four female volunteers wore each of 3 currently marketed feminine hygiene pads and the sensors on the genital area and behind the knee while walking, sitting, and standing for approximately 2 minutes of each activity. Four participants completed the walking and sitting portions of the study and three completed the walking, sitting, and standing portions. The pressure data collected for all 3 pads in both the genital and BTK locations were similar inn both clinical tests. The preliminary results obtained in this clinical pilot study successfully confirm that pressure exerted from feminine hygiene pads in the BTK clinical test model is very similar to real product wear conditions.展开更多
