| 1 | A new distance correction method for sulfur analysis in coal using online XRF measurement system显示文摘When X-ray fluorescence(XRF)technology is used to measure the sulfur concentration in coal online,the measurement accuracy is affected by the coal’s uneven surface and the particle size.In order to improve the accuracy of sulfur concentration measurement,an online measurement system,consisting of a portable X-ray fluorescence instrument and an auxiliary distance correction module,was developed in this paper.By measuring the standard coal samples of known sulfur concentration,we obtained a calibration curve that can be used to analyze the sulfur concentration.We studied the relationship between the X-ray fluorescence intensity(I)and the distance(D)from surfaces to instrument.The results showed that there was a good linear relationship between I and D when the sulfur content was certain.Based on these knowledge,the distance correction formula of X-ray fluorescence intensity was proposed.By applying the distance correction formula to experimental sulfur concentration measurement,we demonstrated that the measurement accuracy can be significantly increased. | JIA WenBao ZHANG Yan GU ChenGuang HEI DaQian LING YongShen SHAN Qing | 2014 | Science China(Technological Sciences)2014，57，1： | 4 |
| 2 | Comparative proteomic study and functional analysis of translationally controlled tumor protein in rice roots under Hg^(2+) stress显示文摘So far,very little is known about mercury stress-induced intercellular metabolic changes in rice roots at the proteome level.To investigate the response of rice roots to mercury stress,changes in protein expression in rice roots were analyzed using a comparative proteomics approach.Six-leaf stage rice seedlings were treated with 50 μmol/L HgCl2 for 3 hr;29 protein spots showed a significant changes in abundance under stress when compared with the Hg2+-tolerant rice mutant and wild type(Zhonghua 11).Furthermore,all these protein spots were identified by mass spectrometry to match 27 diverse protein species.The identified proteins were involved in several processes,including stress response,redox homeostasis,signal transduction,regulation and metabolism;some were found to be cellular structure proteins and a few were unknown.Among the up-regulated proteins,OsTCTP(translationally controlled tumor protein) was chosen to perform hetereologous expression in yeast which was presumed to participate in the Hg2+ tolerance of rice,providing evidence for its role in alleviating Hg2+ damage.Among the many tests,we found that OsTCTP-overexpressed yeast strains were more resistant to Hg2+ than wild-type yeast.Thus,we propose that OsTCTP contributes to Hg2+ resistance.Here we present,for the first time,the functional characterization of OsTCTP in connection with Hg2+ stress in plants. | Feijuan Wang Yongshen Shang Ling Yang Cheng Zhu | 2012 | Journal of Environmental Sciences2012，24，12： | 2 |
