Issue date:May 2011 Publication year:2011 Pages:1497-1502 Language:English ISSN:00405752 CODEN:THAGA6 Document type:Journal article (JA) Publisher:Springer Verlag, Tiergartenstrasse 17, Heidelberg, D-69121, Germany Abstract:Fusarium head blight (FHB) of wheat causes not only significant reduction in grain yield and end-use quality, but also the contamination of the grain with mycotoxins that are detrimental to human and animal health after consumption of infected grain. Growing resistant varieties is an effective approach to minimize the FHB damage. The Chinese wheat landrace Haiyanzhong (HYZ) shows a high level of resistance to FHB. To identify quantitative trait loci (QTL) that contribute to FHB resistance in HYZ, 136 recombinant inbred lines (RIL) were developed from a cross of HYZ and Wheaton, a hard spring wheat cultivar from the USA. The RIL and their parents were evaluated for percentage of scabbed spikelets (PSS) in both greenhouse and field environments. Five QTL were detected for FHB resistance in HYZ with one major QTL on 7DL. The 7DL QTL peaked at SSR marker Xwmc121, which is flanked by the SSR markers Xcfd46 and Xwmc702. This QTL explained 20.4-22.6% of the phenotypic variance in individual greenhouse experiments and 15.9% in a field experiment. Four other minor QTL on 6BS (two QTL), 5AS and 1AS each explained less than 10% of the phenotypic variance in individual experiments. HYZ carried the favorable alleles associated with FHB resistance at the QTL on 7DL, 6BS and 5AS, and the unfavorable allele at the QTL on 1AS. The major QTL on 7D can be used to improve the FHB resistance in wheat breeding programs and add diversity to the FHB resistance gene pool. © 2011 Springer-Verlag.

And then the solid complexes of calix[8]arene ketone derivative with Praseodymium or Europium were further synthesized. Elemental analysis, infrared spectra, 13CNMR, XRD and thermal spectra were used to characterize the products. The results show that two kinds of the solid complexes are mononuclear molecules, central rare earth metal ions are coordinated by six oxygen atoms from two calix[8]arene ketone derivative and three nitrogen atoms from three N, N-Dimethylformamide molecules, leading to formation of nine-coordinated solid complexes with symmetrical tricapped trigonal prism structure.

Box 211, Amsterdam, 1000 AE, Netherlands Abstract:In the global competition, companies are propelled by an immense pressure to innovate. The trend to produce more new knowledge-intensive products or services and the rapid progress of information technologies arouse huge interest on knowledge management for innovation. However the strategy of knowledge management is not widely adopted for innovation in industries due to a lack of an effective approach of their integration. This study aims to help the designers to innovate more efficiently based on an integrated approach of knowledge management. Based on this integrated approach, a prototype of distributed knowledge management system for innovation is developed. An industrial application is presented and its initial results indicate the applicability of the approach and the prototype in practice. © 2011 Elsevier B.V. All rights reserved.

Taking minimal daily electric cost of single pump station as objective function, allocation of water quantity pumped by each station as coordinated variable, this model was decomposed into several first stage sub-model of daily optimal operation for single pump station. Then taking minimal daily electric cost of single pump unit as objective function, allocation of water quantity pumped by each unit as coordinated variable, the first stage sub-model was decomposed into several second stage sub-model of daily optimal operation for single pump unit which takes the blade angle or unit speed as decision variable, the discrete value of water quantity pumped by each unit as state variable, and was solved by means of dynamic programming method. The constructed aggregation model took daily water quantity pumped by each pump unit as decision variable, the discrete value of water quantity pumped by parallel station group as state variable, and was also solved by dynamic programming method. This method could solve the optimal operation issues for parallel pumping stations with various operation modes, time period divisions and daily average heads of each station, and also provide theoretical support for the study on optimal operation of multi-stage pumping stations. Taking No.1, 3 Huaiyin pumping station as a study case, a series of optimization calculations were carried out. The results showed that the unit cost of optimal operation under 100%, 80%, and 60% loads within all average daily heads had an average energy consumption saving of 10.53%, 26.54% and 34.40%, respectively, compared with the operation with fixed blade angle and constant speed.

Based on normal tensile stress-strain relationship, tensile stress-strain constitutive relationship of concrete after freeze-thaw cycles was proposed. The results show that the slope of the rising part of tensile stress-strain curve falls down gradually and the peaks of tensile stress and strain decrease linearly as cycle times of freeze-thaw increase. Samples with high strength grade express less decrease of peak tensile stress and strain than those with low strength grade for the same freeze-thaw cycles, while decreasing rate has slight difference.

Box 136, Harbin, 150001, China Abstract:To realize adjusting the fire intensity of cooking robot continuously, a numerical calculation and experiments of dual-pressure fire system for blast gas combustor were carried out. Firstly, the basic equations of fluid mechanics, the equations of component transport and the equations of turbulence for the induction tunnel of combustor were established. Secondly, the CFD software FLUENT was utilized to build the two dimensional axisymmetry gas-kinetic model for the induction tunnel, to define the boundary condition, the initial state and the finite-rate chemical reaction model. Thirdly, the control method of dual-pressure fire intensity was obtained. According to the variation curve of pressure value of high-pressure air in the nozzle central axle with the accelerating value of combustible gas and quantity of air imbibed by ejection, the optimal matched pressure value of high-pressure air based on the specific heat load of combustible gas was obtained. The method was used on the cooking robot, which showed that the fire intensity feedback control could be achieved precisely and the power of common pressure (2.0 kPa) combustible gas combustor could be up to 18 kW.
