The common soil arthropod Folsomia candida can survive well when fed only maize pollen and thus may be exposed to insecticidal proteins by ingesting insect-resistant genetically engineered maize pollen containing Bacillus thuringiensis (Bt) proteins when being released into the soil. Laboratory experiments were conducted to assess the potential effects of Cry1Ab/Cry2Aj-producing transgenic Bt maize (Shuangkang 12–5) pollen on F. candida fitness. Survival, development, and the reproduction were not significantly reduced when F. candida fed on Bt maize pollen rather than on non-Bt maize pollen, but these parameters were significantly reduced when F. candida fed on non-Bt maize pollen containing the protease inhibitor E-64 at 75 μg/g pollen. The intrinsic rate of increase (rm) was not significantly reduced when F. candida fed on Bt maize pollen but was significantly reduced when F. candida fed on non-Bt maize pollen containing E−64. The activities of antioxidant-related enzymes in F. candida were not significantly affected when F. candida fed on Bt maize pollen but were significantly increased when F. candida fed on non-Bt pollen containing E−64. The results demonstrate that consumption of Bt maize pollen containing Cry1Ab/Cry2Aj has no lethal or sublethal effects on F. candida. © 2017 Elsevier Ltd

To validate the key parameters of the real time PCR method for GM maize T25, 7 different laboratories are chosen to assign the reference values of three different GM content matrix reference materials by using the same method. Although different types of instruments are used by different labs, the standard curve generated by each lab is comparable which indicated that this method shows a good reproductablity. After statistically analyzing the data gained from seven labs, the total means are assigned to be the reference values. The reference values and expanded uncertainties (k=2) for three matrix GM reference material are 1.17%±0.22%, 2.17%±0.38% and 9.81%±2.30%.

The key parameters of the real time PCR method for genetically modified canola T45 were validated , the results show that the real time PCR method can be used to co-validate the reference value for GM canola T45 reference material. Six laboratories are chosen to characterize the property values of GM T45 plasmid reference materials with the same method. The slop (PCR amplification efficiency), intercept and linearity coefficient of GM T45 genomic DNA and plasmid DNA are analyzed. The results show that the PCR amplification efficiency and linearity coefficient between genomic DNA and plasmid DNA are not significantly different. The statistic test shows the data from different labs are equal. The property value and expanded uncertainties for GM canola T45 plasmid reference material is 0.98 ± 0.02 (k=2).

As urban development and residents low-carbon living requirements, the green transportation occurs. The development of green transportation system should be under the guidance of green transportation development architecture. On the base of the international and domestic studies and practices, this paper firstly summarized the content of green transportation system and its development objectives, and then the framework of green transportation architecture was presented. Secondly, the evaluation index architecture of green transportation system was analyzed, and the specific estimation method for the selected evaluation index was given. Finally, based on the case study of the green transportation evaluation index values for different types of urban areas, the development emphasis of urban green transportation system of various types of urban areas were pointed out. The study is promising for providing a good guidance to the development of domestic urban green transportation system © 2013 Taylor & Francis Group, London.

Substrate enzyme plays an important role in the transformation and the degradation processes of nutrients in constructed wetlands. The spatial distribution of the substrate enzymes, including urease, dehydrogenase and phosphatase, was monitored systematically. Meanwhile, the spatial distribution of dissolved oxygen and the spatial degradation rule of nutrients were investigated. The relationship between the enzyme activities and wetland operation characteristics was analyzed. Results showed that there was a close relationship between the spatial distribution of dissolved oxygen, the spatial degradation regularity of nutrients, and the enzyme activities. The activity of urease, dehydrogenase and phosphatase in the upper layer of soil was generally higher than that in the lower layer. The distribution regularity of the urease activity was similar with that of dissolved oxygen. The activity of dehydrogenase and phosphatase declined gradually along the flow in the wetland. The urease activity influenced the nitrification intensity significantly, showing a remarkable positive correlation with the nitrification intensity in the wetland. The dehydrogenase activity had no significant correlation with the nutrient removal, but was associated with the accumulation of organic matters in the substrates. The phosphatase activity was closely related to degradation of organophosphorus.

The L-shaped fiber reinforced polymer (FRP) bonding method for enhancing the flexural performance of negative moment region of RC beams is proposed, in which angle steel is settled to anchor FRP sheet at the frame joint. Six full scale frame joint specimens were tested under static load or low frequency cyclic load. Then, the failure mode, flexural capacity, stiffness, ductility and energy dissipation ability were compared between the RC beams strengthened by the proposed L-shaped FRP bonding method and those strengthened by the recommended method in current specification. The experimental results show that by the L-shaped FRP bonding method, deformation coordination between the FRP at the beam root and the corresponding section of the frame beam are achieved in the process of loading, and thus the stress-strain relationship basically agrees with the plane cross-section assumption. Under low frequency cyclic load, the increase of flexural capacity and stiffness of the beam are almost the same as those under the action of static loads. The trend of FRP debonding vertically from the surface of concrete can be completely restricted by the anchor device and thus more stable strengthening effect is achieved.
