1规模化秸秆沼气发酵反应器中微生物群落特征显示文摘采用末端限制性多态性分析(T-RFLP)和克隆文库构建相结合的研究方法,对以秸秆为唯一或主要原料的四个沼气发酵反应器中的细菌和古菌群落特征进行分析,结果表明:(1)供试秸秆沼气反应器中细菌种类十分丰富,分属于9个门,其中厚壁菌门(Firmicutes)、变形菌门(Proteobacteria)与拟杆菌门(Bacteroidetes)为优势种群,在四个沼气反应器中的相对丰度分别为19.3%~47.2%、4.8%~24.3%与2.5%~15.5%。水解与发酵性细菌为各反应器中的优势种群;(2)古菌种类明显少于细菌,均属于甲烷杆菌纲(Methanobacteria)和甲烷微菌纲(Methanomicrobia)。在以秸秆为唯一原料的反应器中,甲烷鬃菌属(Methanosaeta)为优势种群,相对丰度为69.2%~71.9%;而在添加猪粪的反应器中,甲烷八叠球菌属(Methanosarcina)为优势种群,相对丰度为73.1%。张蕾 梁军锋 崔文文 杜连柱 高文萱 Xinmei Feng Anna Schnürer 2014农业环境科学学报2014,33,3:15
2双渠道多级分销网络选址—库存问题显示文摘针对分销网络中各节点独立决策与全局最优并存的现实需求,引入目标级联法用于解决双渠道多级分销网络选址—库存问题。构建了多层级、多节点、多主体的三层级问题求解模型,并采用底层先收敛、局部用遗传算法的协调策略进行求解,实现选址决策、库存决策与线上需求分配决策。以某红酒企业的双渠道分销网络运作模式为案例,对选址—库存模型进行求解与结果分析,并与传统的一体化优化方法的求解效果进行对比,验证了目标级联法在求解选址—库存问题的有效性;通过对需求方差的变化进行敏感性分析表明,为降低需求不确定性对企业物流总成本的影响,应及时优化供应链结构,调整线上需求分配的层级。孙姣 屈挺 聂笃宪 Matthias Thürer 李从东 黄国全 2021计算机集成制造系统2021,27,11:3
3Beta-7 integrin controls enterocyte migration in the small intestine显示文摘AIM:To hypothesize that beta-7 integrin affects cellularmigration of both,lymphocytes and enterocytes.METHODS:The nucleoside analog Brd U was ip injected in beta-7-deficient mice(C57BL/6-Itgbtmlcgn/J)of male gender and age-matched male C57BL/J J mice(wild type)4,20,or 40 h before analysis.The total small intestine was isolated,dissected,and used for morphometrical studies.Brd U-positive epithelial cells were numbered in at least 15 hemi-crypts per duodenum,jejunum,and ileum of each animal.The outer most Brd U-positive cell(cellmax)was determined per hemi-crypt,numerically documented,and statistically analysed.RESULTS:Integrins containing the beta-7-chain were exclusively expressed on leukocytes.In the small intestinal mucosa of beta-7 integrin-deficient mice the number of intraepithelial lymphocytes was drastically decreased.Moreover,the Peyer’s patches of beta-7integrin-deficient mice appeared hypoplastic.In beta-7integrin-deficient mice the location of cellmax was found in a higher position than it was the case for the controls.The difference was already detected at 4 h after Brd U application,but significantly increased with time(40 h after Brd U injection)in all small intestinal segments investigated,i.e.,duodenum,jejunum,and ileum.Migration of small intestinal enterocytes was different between the experimental groups measured by cellmax locations.CONCLUSION:The E-cadherin beta-7 integrin pathway probably controls migration of enterocytes within the small intestinal surface lining epithelial layer.Elke Kaemmerer Paula Kuhn Ursula Schneider Thomas Clahsen Min Kyung Jeon Christina Klaus Julia Andruszkow Michael Hrer Sabine Ernst Angela Schippers Norbert Wagner Nikolaus Gassler 2015World Journal of Gastroenterology2015,21,6:3
