Chemical Research in Chinese Universities 2007年第4期23卷 479-482页

作者： YANG Ai-li jiang wen-ju College of Architecture and Environment Sichuan University Chengdu 610065 P. R. China

A new quaternary ammonium salt monomer was synthesized and a quaternary amination of lignin（ noted as QL）, with the monomer was carried out by grafting copolymerization. The products were characterized by Fourier Transform Infrared spectroscopy（ FTIR）. The experimental results indicate that the yield of the monomer was 99.06%, and the conversion of the monomer and the grafting yield of QL were 93.69% and 185.78%, respectively. The feasibility of QL as the flocculant to be applied in color removal of five artificial dyes, erioehrome black T（dye A）, gongo red（dye B ）, direct fast black G （dye C ）, cuprofix blue green B （dye D ）, and acid black ATT （dye E ） was examined. Results show that OL exhihits the favorable flocculation nerformance and high stability.

Journal of Integrative Agriculture 2013年第8期12卷 1341-1349页

Although water and energy resources are well-recognized concerns regarding economic and social development sustainability, little specific research has focused on both water and energy problems at the same time. This study analyzed the water and electricity-use patterns in Shenzhen, South China during 2001-2009. A curve regression method was used to examine the relationship between water and electricity use per gross domestic product （GDP） in Shenzhen and its three sectors, i.e., agriculture, industry ＆ construction, and residential life ＆ services. Results showed that agriculture only covered less than 10% of water and electricity use in Shenzhen, while industry ＆ construction and residential life ＆ services accounted for more than 90% of water and electricity use in Shenzhen, which coincided with the city＇s industrial structure. The water and electricity use per GDP in agriculture was the biggest among three sectors in Shenzhen during 2001-2009, which means inefficiency of water and electricity use in agriculture. Due to transitioning to advanced materials and manufacturing, both water and electricity use per GDP their utilization efficiencies gradually increased over time. in industry ＆ construction decreased during 2001-2009 and The same held true for those in residential life ＆ services transformed toward modern business, creative culture, finance services, etc. Derived from the survival of the fittest in competing for limited water and electricity resources, agriculture in Shenzhen has been gradually substituted by industry ＆ construction and residential life ＆ services, with much higher efficiencies of water and electricity use. And traditional agriculture will not be sustainable in the process of urbanization and industrialization, except high-tech intensive agriculture with low water and energy cost. Furthermore, by means of curve regression, we found that there was a significant quadratic relationship between water use per GDP and electricity use per GDP

螺蛳粉汤料包味道鲜美,但原料利用率低,螺肉固有的腥味严重影响其应用前景。文章以新鲜石螺肉为原料,通过氮回收率和水解度评价炒制对螺肉蛋白利用的影响,并结合顶空固相微萃取-气质联用技术(HS-SPME-GC-MS)探究美拉德反应对炒制/未炒制的石螺肉挥发性成分的影响。结果显示,未炒制的石螺肉水解度低于炒制组,但其蛋白质回收率远高于炒制组,达67.60%。GC-MS共检测出154种挥发性化合物,炒制后样品中挥发性物质较新鲜样品减少,酶解组样品中数量也出现明显减少。而美拉德反应后,形成了苯乙醛、2-乙基呋喃等香气成分,具有不良气味的壬醛、3-庚酮等物质的相对含量降低,且新鲜组去腥效果更明显。上述结果为石螺肉酶解产物脱腥工艺及石螺呈味基料的制备提供了理论基础。

红枣、核桃以及苹果是陕北地区主要的人工经济林树种,且种植方式单一。为探讨人工经济林对牧草生长的化感作用,本研究以紫花苜蓿和黑麦草作为研究受体,通过设置不同浓度核桃、苹果、红枣凋落叶浸提液,分析其对豆禾草种种子萌发及幼苗生长的影响。结果表明:1)紫花苜蓿和黑麦草的发芽率和发芽势随浸提液浓度的增加而显著降低(P<0.05);2)苹果和红枣凋落叶浸提液浓度越高,紫花苜蓿、黑麦草幼苗叶绿素含量和根系活力越低,核桃凋落叶浸提液处理下黑麦草幼苗的叶绿素含量显著高于对照组,根系活力显著低于对照组(P<0.05);3)两种牧草的生化指标结果表明,黑麦草的抗氧化能力强于紫花苜蓿。豆禾草种种子萌发及幼苗生长对不同树种、不同浓度凋落叶浸提液的化感响应存在差异,整体而言,人工经济林凋落叶浸提液对紫花苜蓿的化感作用强于黑麦草。本研究旨在为陕北地区林草混种提供理论依据,在建植过程中应充分考虑豆禾草种与经济林的搭配。

Vacuolar sorting receptors （VSRs） are type I integral membrane proteins that mediate the vacuolar transport of soluble cargo proteins via prevacuolar compartments （PVCs） in plants. Confocal immunofluorescent and immunogold Electron Microscope （EM） studies have localized VSRs to PVCs or multivesicular bodies （MVBs） and trans-Golgi network （TGN） in various plant cell types, including suspension culture cells, root cells, developing and germinating seeds. Here, we provide evidence that VSRs reach plasma membrane （PM） in growing pollen tubes. Both immunofluorescent and immunogold EM studies with specific VSR antibodies show that, in addition to the previously demonstrated PVC/MVB localization, VSRs also localize to PM in lily and tobacco pollen tubes prepared from chemical fixation or high-pressure freezing/frozen substitution. Such a PM localization suggests an additional role of VSR proteins in mediating protein transport to PM and endocytosis in growing pollen tubes. Using a high-speed Spinning Disc Confocal Microscope, the possible fusion between VSR-positive PVC organelles and the PM was also observed in living tobacco pollen tubes transiently expressing the PVC reporter GFP-VSR. In contrast, the lack of a prominent PM localization of GFP-VSR in living pollen tubes may be due to the highly dynamic situation of vesicular transport in this fast-growing cell type.
