1Evaluation of non-point source pollution reduction by applying Best Management Practices using a SWAT model and QuickBird high resolution satellite imagery显示文摘This study evaluated the reduction effect of non-point source pollution by applying best management practices (BMPs) to a 1.21 km 2 small agricultural watershed using a SWAT (Soil and Water Assessment Tool) model.Two meter QuickBird land use data were prepared for the watershed.The SWAT was calibrated and validated using daily streamflow and monthly water quality (total phosphorus (TP),total nitrogen (TN),and suspended solids (SS)) records from 1999 to 2000 and from 2001 to 2002.The average Nash and Sutcliffe model efficiency was 0.63 for the streamflow and the coefficients of determination were 0.88,0.72,and 0.68 for SS,TN,and TP,respectively.Four BMP scenarios viz.the application of vegetation filter strip and riparian buffer system,the regulation of Universal Soil Loss Equation P factor,and the fertilizing control amount for crops were applied and analyzed.MiSeon Lee GeunAe Park MinJi Park JongYoon Park JiWan Lee SeongJoon Kim 2010Journal of Environmental Sciences2010,22,6:34
2三个耐冻性不同的马铃薯野生种中FAD2基因的克隆及表达分析显示文摘以3个耐冻性和冷驯化能力不同的马铃薯野生种Solanum commersonii、S.acaule和S.cardiophyllum为材料,利用RT-PCR技术克隆出不饱和脂肪酸合成途径中的关键酶基因ω-6脱氢酶基因(FAD2),分别命名为Cmm-FAD2(GenBank登录号为KF214782)、Aca-FAD2(KF214781)和Cph-FAD2(KF214783)。序列分析表明,该基因在3个马铃薯野生种中核苷酸长度都为1326 bp,编码441个氨基酸残基。3个野生种FAD2基因核苷酸序列和蛋白序列比对结果表明,在18个位点的差异核苷酸中有8个位点的差异导致对应的氨基酸残基变化,其中第11和第44氨基酸残基处,耐冻且有冷驯化能力的S.commersonii和S.acaule有相同的氨基酸,而冷冻敏感S.cardiophyllum的氨基酸却不同。二级结构预测结果表明S.commersonii和S.acaule的FAD2蛋白与S.cardiophyllum FAD2蛋白的α-螺旋、延伸链和随机卷曲存在明显差异。蛋白多序列比对和进化树分析表明,3个马铃薯野生种的FAD2基因与番茄的亲缘关系最近,其次是与马齿笕。qPCR分析表明,12 d冷驯化使FAD2基因在3个马铃薯野生种中都上调表达,S.commersonii和S.acaule的FAD2基因表达水平均高于S.cardiophyllum,且差异显著。李飞 徐建飞 刘杰 段绍光 卞春松 Jiwan P.PALTA 金黎平 2014作物学报2014,40,1:8
3冷驯化前后野生马铃薯Solanum acaule内参基因的筛选显示文摘为找到表达稳定性最好的内参基因,利用实时荧光定量PCR技术分析了4个内参基因ef1-a、Actin、β-tubulin2和β-tubulin3在野生马铃薯S.acaule冷驯化前后的表达稳定性。结果表明:β-tubulin2和ef1-a表达均稳定,Actin变化最大。因此,β-tubulin2和ef1-a适宜作为野生马铃薯S.acaule的内参基因。李飞 徐建飞 刘杰 段绍光 雷尊国 Jiwan Palta 金黎平 2012西南农业学报2012,25,5:7

6Multi-color luminescence in Eu^3+/Tb^3+ co-doped ZnAl amorphous materials and their annealed samples显示文摘Multi-color luminescence basing on amorphous Eu^(3+)/Tb^(3+) co-doped Zn-Al hydroxides and their annealed samples were studied in detail. Results suggest that excellent red emissions due to Eu^(3+) and green emissions attributed to Tb^(3+) appear under the excitation of favorable wavelength for all the asprepared amorphous samples. Moreover, the emission intensity depends on the Eu^(3+)/Tb^(3+) molar ratio. The samples annealed at 300, 500, and 700 ℃ still exhibit amorphous state,and multi-color luminescence kept in the samples annealed at 300 ℃, while luminescence quenched for the samples annealed at 500 and 700 ℃. However, a broad emission ranging from 450 to 650 nm occurs in some samples annealed at 900 ℃. Further, the fluorescence decay and lifetimes for the as-prepared samples and the samples annealed at 300 ℃ were investigated. It is found that all the decay curves of emissions due to Tb^(3+) and Eu^(3+) present characteristic double exponential function despite their different lifetimes.The present work may be a good example for developing new multi-color even white light emitting materials.Yufeng Chen Jiwan Zhang Yanmei Hu Xiaoqing Wang Li Wang 2018Journal of Rare Earths2018,36,11:2

18A multi-channel chemical sensor and its application in detecting hydrothermal vents显示文摘There are well-established chemical and turbidity anomalies in the plumes occurring vicinity of hydrothermal vents, which are used to indicate their existence and locations. We here develop a small, accurate multi-channel chemical sensor to detect such anomalies which can be used in deep-sea at depths of more than 4 000 m. The design allowed five all-solid-state electrodes to be mounted on it and each (apart from one reference electrode) could be changed according to chemicals to be measured. Two experiments were conducted using the chemical sensors. The first was a shallow-sea trial which included sample measurements and in situ monitoring. pH, Eh, CO3^2- and SO4^2- electrodes were utilized to demonstrate that the chemical sensor was accurate and stable outside the laboratory. In the second experiment, the chemical sensor was integrated with pH, Eh, CO3^2- and H2S electrodes, and was used in 29 scans of the seabed along the Southwest Indian Ridge (SWIR) to detect hydrothermal vents, from which 27 sets of valid data were obtained. Hydrothermal vents were identified by analyzing the chemical anomalies, the primary judging criteria were decreasing voltages of Eh and H2S, matched by increasing voltages of pH and CO3^2- . We proposed that simultaneous detection of changes in these parameters will indicate a hydrothermal vent. Amongst the 27 valid sets of data, five potential hydrothermal vents were targeted using the proposed method. We suggest that our sensors could be widely employed by marine scientists.Zhen Cai A J Mur Luis Jiwan Han Kui Wang Huawei Qin Ying Ye 2019Acta Oceanologica Sinica2019,38,9:1
