Wheat variety Ji 84-5418 has been bred on this model. The analysis results of high-yield and stability indicated that Ji 84-5418 was not only an aggregate of varied excellent characters,but a recombined biotype which could early differentiate spike and develop coordi-nately,and had better self-regulation ability and potential high productivity. Its yield is stable at 6000-8250 kg/ha.展开更多

A total of 1030 middle-aged women living in all parts of Japan participated in this study through internet research from September 2010 to May 2011. The participants were evaluated on the basis of a battery of questionnaires mainly including demographics, perceived breast cancer risk, worry about breast cancer, mammography testing beliefs, intentions to use mammography, seeking information about mammography, and actual usage of mammography thrice over an eight-month period. The main results were as follows: 1) Perceived risk and cancer worry affected the intention of undergoing mammography, and this effect was mediated by beliefs about mammography testing. 2) Intention to use mammography and past mammography usage predicted future usage of mammography, with past mammography usage being the strongest predictor. 3) Information seeking about mammography was the strongest predictor of using mammography during the eight-month follow-up period of middle-aged women who had not undergone any mammography testing. PPM was a useful model to explain the mechanism behind middle-aged Japanese women’s intentions to use mammography, as well as their actual usage of mammography. In addition, past mammography experience was the strongest predictor of regular mammography usage and information seeking was a critical factor for the first-usage of mammography.展开更多

It will start by making a comparison between thermopile, bolometer and pyroelectric technologies. Although sensitivity performances available with bolometers appear to be better at first sight, it is found that thermopiles have non-negligible advantages that make them more suitable for this application field. Then the different steps necessary for the design will be described, starting from the thermoelectric model of the sensor (temperature gradient, electrical sensitivity, etc.) and considering all steps up to technological manufacturing in a clean room. The results obtained on the structures produced on a specific computer-controlled measurement bench (temperature regulation with an onboard preamplification card) will be presented. Finally, the results prove that the square structures have better performances (S = 82 V/W and NETD = 208 mK).展开更多
