ZnO-CeO2 nanostructures were synthesized by simple and effcient low temperature method. The structure and morphology of the ZnO-CeO2 nanostructures were characterized by X-ray powder diffraction （XRD） and field emission scanning electron microscopy （FESEM）, which revealed elongated shaped CeO2 nanoparticles with diameters of 40–90 nm distributed on the surface of elongated ZnO nanostructures with diameters of 50–200 nm （edge–centre）. Further the structure of the synthesized ZnO-CeO2 nanostructure was supported by Raman spectra and Fourier transform infrared spectroscopy （FTIR）. UV-vis absorption spectrum was used to confirm the optical properties of the CeO2 doped ZnO nanostructures. Photo-catalytic activity of CeO2 doped ZnO nanostructure was evaluated by degradation of acridine orange and methylene blue which degraded 84.55% and 48.65% in 170 min, respectively. ZnO-CeO2 nanostructures also showed good sensitivity （0.8331 μA·cm-2·（mol/l）-1） in short response time （10 s） by applying to chemical sensing using ethanol as a target compound by I-V technique. These degradation and chemical sensing properties of ZnO-CeO2 nanostructures are of great importance for the application of ZnO-CeO2 system as a photo-catalyst and chemical sensor.

5-Aminolevulinic acid alleviates herbicide-induced physiological and ultrastructural changes in Brassica napus

It is well known that application of 5-aminolevuJinic acid （ALA） could promote the plant growth under abiotic stress in oilseed rape （Brassica napus L.）. However, the specifics of its physiological and ultrastructural regulation under herbi- cide stress conditions are poorly understood. In the present study, alleviating role of ALA in B. napus was investigated under four levels of herbicide propyl 4-（2-（4,6-dimethoxypyrimidin-2-yloxy） benzylamino） benzoate （ZJ0273）（0, 100, 200 and 500 mg L-1） with or without 1 mg L-1 ALA treated for 48 or 72 h. Results showed that after 48 h of herbicide stress, the growth of rape seedlings was significantly inhibited with the successive increases of the ZJ0273 concentrations from 0 to 500 mg L-1, but this inhibition was obviously alleviated by exogenous application of ALA. However, when treatment time prolonged to 72 h, the recovery effects of ALA could not be evaluated due to the death of plants treated with the highest concentration of ZJ0273 （500 mg L-1）. Further, the root oxidizability and activities of antioxidant enzymes （superoxide dismutase, perox- idase and ascorbate peroxidase） were dramatically enhanced by the application of 1 mg L-1 ALA under herbicide stress. Therefore, plants treated with ALA dynamically modulated their antioxidant defenses to reduce reactive oxygen species （ROS） accumulation and malondialdehyde （MDA） content induced by herbicide stress. Additionally, exogenously applied ALA improved the ultrastructure＇s of chloroplast, mitochondria and nucleus, and induced the production of stress proteins. Our results suggest that ALA could be considered as a potential plant growth regulator for the improvement of herbicide tolerance through alleviation of the physiological and ultrastructural changes induced by the herbicide in crop production.

Factors influencing hybrid maize farmers' risk attitudes and their perceptions in Punjab Province,Pakistan

引用

Journal of Integrative Agriculture 2018年第6期17卷 1454-1462页

作者： Shoaib Akhtar LI Gu-cheng Raza Ullah Adnan Nazir muhammad Amjed Iqbal muhammad Haseeb Raza Nadeem Iqbal muhammad faisal College of Economics & Management Huazhong Agricultural University Institute of Agricultural and Resource Economics University of Agriculture Faisalabad The Management School Lancaster University

Hybrid maize farmers have to face diverse kinds of climate, biological, price and financial risks. Farmers＇ risk perceptions and risk attitudes are essential elements influencing farm operations and management decisions. However, this important issue has been overlooked in the contemporary studies and therefore there is a dearth of literature on this important issue. The present research is therefore, an attempt to fill this gap. This study aims to quantify hybrid maize farmers＇ perceptions of disastrous risks, their attitudes towards risk and to explore the impacts of various farm and farm household factors on farmers＇ risk attitudes and risk perceptions. The present study is conducted in four hybrid maize growing districts of Punjab Province, Pakistan, using cross-sectional data of 400 hybrid maize farmers. Risk matrix and equally likely certainty equivalent （ELCE） method are used to rank farmers＇ perceptions of four catastrophic risk sources including climate, biological, price and financial risks and to investigate farmers＇ risk aversion attitudes, respectively. Furthermore, probit regression is used to analyze the determinants affecting farmers＇ risk attitudes and risk perceptions. The results of the study showed that majority of farmers are risk averse in nature and perceive price, biological and climate to be potential sources of risks to their farm enterprise. In addition, analysis divulges that distance from farm to main market, off-farm income, location dummies for Sahiwal and Okara, age, maize farming experience, access to extension agent, significantly （either negatively or positively） influence farmers＇ risk attitudes and risk perceptions. The study delivers valuable insights for farmers, agricultural insurance sector, extension services researchers and agricultural policy makers about the local understanding of risks to hybrid maize crop in developing countries, like Pakistan, and have implications for research on farmers＇ adaptation to exposed risks.

催化学报 2013年第9期34卷 1756-1761页

作者： muhammad Asgher Bazgha aslam Hafiz muhammad Nasir Iqbal Industrial Biotechnology Laboratory Department of Chemistry and BiochemistryUniversity of Agriculture

Solid state bio-processing of wheat straw was carried out through an indigenous fungal strain Pleurotus ostreatus IBL-02 under pre-optimized fermentation conditions. The maximum activity, 692±12 U/mL, of the industrially important manganese peroxidase (MnP) enzyme was recorded after five days of still culture incubation. The crude MnP was 2.1-fold purified with a specific activity of 860 U/mg after purification on a Sephadex-G-100 gel column. On native and SDS-PAGE electrophoresis gels, the purified MnP fraction was a single homogenous band of 45 kDa. An active fraction of MnP was immobilized using hydrophobic sol-gel entrapment comprising tetramethoxysilane (T) and propyltrimethoxysilane (P) at different T:P molar ratios. Characterization revealed that after 24 h incubation at varying pH and temperatures, the MnP fraction immobilized at a T:P ratio of 1:2 in the sol-gel retained 82% and 75% of its original activity at pH4 and 70 ℃, respectively. The optimally active fraction at a 1:2 T:P ratio was tested against MnSO4 as a substrate to determine the kinetic catalytic constants KM and Vmax . To explore the industrial applicability of P. ostreatus IBL-02 MnP, both the free and immobilized MnP were used for the decolorization of four different textile industrial effluents. A maximum of 100% decolorization was achieved for the different textile effluents within the shortest time period. A lower KM , higher Vmax , hyper-activation, and enhanced acidic and thermal resistance up to 70 ℃ were the novel catalytic features of the sol-gel immobilized MnP, suggesting that it may be a potential candidate for biotechnological applications particularly for textile bioremediation purposes.

如今,使用小型薄膜直流链路电容器代替大型电解电容器,以提高IPMSM驱动器中逆变器的可靠性和寿命。然而,由于直流链路电容器的容量显着降低,其中存储的能量很难使直流链路电压保持恒定。结果,通常直流链路电压随输入电网电压的两倍频率而波动。针对这个问题研究人员进行了广泛的研究来调节这些直流链路电压振荡,其中大多数拓扑为标准六开关三相逆变器,用于IPMSM的电力驱动。此外,在该标准逆变器中还没有考虑电动机速度瞬变和负载变化对DC链路电压振荡的影响,其中大多数输入电网控制与电动机控制耦合使得控制非常复杂。本文提出了一种由半控整流器供电的低成本四开关三相逆变器（FSTPI）的无电解电容控制方案,该方案不仅可以在恒速下调节直流环节电压振荡,还可以在速度瞬变和输入扭矩变化期间调节直流环节电压振荡。小薄膜电容器吸收的功率通过控制其中的存储能量来调节,其目的是使DC链路电压跟踪其参考值。通过仿真结果验证了所提方法的有效性。观察到输入电网电流的谐波符合IEC 61000-3-2标准.
