Interspecific competition between Encarsiaformosa and Encarsia sophia, two major parasitoids of Bemisia tabaci, and the influence of five tomato varieties on competition outcome were investigated under laboratory conditions. E. formosa parasitized more B. tabaci than E. sophia when in single wasp assays on any of the tomato varieties investigated. When B. tabaei nymphs were exposed to both wasp species （either simultaneously or sequentially）, the number of B. tabaci nymphs parasitized by either wasp species was significantly decreased compared to the sole access condition. Total mortality of B. tabaci was increased when B. tabaci nymphs were exposed to both wasp species compared to only one wasp species. Thus competition between *** and E. sophia apparently reduced parasitoid offspring numbers, but not the efficiency of biological con- trol. In fact, control efficiency was enhanced in some cases, particularly on tomato variety Huangtuoyuan （HTY）. When wasps were allowed sequential access to hosts, interference occurred through host feeding by the second wasp, especially if it was E. sophia. The effect of different tomato varieties was not significant.

A new organocatalytic double annulation cascade involving scission/recombination of N-O bonds of nitrones is reported for the first time, and used to produce a range of hitherto unprecedented tricyclic bridged-fused benzo[d]azepines bearing three stereogenic centers with moderate to good yields and complete diastereoselectivity. A quinine-catalyzed reaction of yne–allenone esters with nitrones worked well and provided a convergent and regioselective pathway to access these three-dimensional scaffolds from the planar conjugated system. Density functional theory(DFT) calculations have been applied to understand the key process for forming diradical intermediates.

本论文从刺参中分离纯化得到一种海参肽,并研究其对NIH/3T3细胞增殖和胶原蛋白分泌的影响。采用活性追踪的方法从新鲜刺参中通过离子交换层析、凝胶层析分离纯化得到海参肽SP12,采用MTT法检测SP12对NIH/3T3细胞的增殖作用;采用流式细胞术检测SP12对NIH/3T3细胞细胞周期的影响;采用羟脯氨酸测定试剂盒的方法检测SP12对NIH/3T3细胞胶原蛋白分泌的影响;采用Western Blot及RT-PCR的方法,在蛋白水平及基因水平上检测SP12对NIH/3T3细胞I型胶原蛋白、MMP-1及TIMP-1表达的影响。结果表明SP12能显著提高NIH/3T3细胞的增殖率,能促进NIH/3T3细胞由G1期向S期转变,增加其胶原蛋白的分泌量,且在0~20μg/mL范围内均呈剂量依赖性。在蛋白水平和基因水平,SP12均能显著促进I型胶原蛋白及TIMP-1的表达,抑制MMP-1的表达,这可能是SP12促进NIH/3T3细胞胶原蛋白分泌的作用机制。

对网络化制造环境下基于收入共享的供应链契约问题进行研究,建立了供应链契约模型,模型中引入惩罚因子,以此分析博弈过程中的利润损失。在以制造商为主导的契约模式下,从收入共享契约的角度研究制造商和零售商组成的二级供应链;通过Stackelberg博弈分析,阐述收入分享比例、订货量、批发价格等相关参数对利润函数的影响,提出分散供应链和集中供应链两种情况下制造商和零售商之间博弈协调策略。最后通过MATLAB数值仿真,得到这种契约模式下的博弈结果,仿真结果也表明了惩罚因子对供应链利润有较大的影响。
