In this study,a denitrification(DN)–partial nitritation(PN)–anaerobic ammonia oxidation(Anammox)system for the efficient nitrogen removal of mature landfill leachate was built with a zone-partitioning self-reflux biological reactor as the core device,and the effects of changes in seasonal temperature on the nitrogen removal in non-temperature-control environment were *** results showed that as the seasonal temperature decreased from 34℃to 11.3℃,the total nitrogen removal rate of the DN-PN-Anammox system gradually decreased from the peak value of 1.42 kg/(m^(3)·day)to 0.49 kg/(m^(3)·day).At low temperatures(<20℃),when the nitrogen load(NLR)of the system is not appropriate,the fluctuation of high NH_(4)^(+)-N concentration in the landfill leachate greatly influenced the stability of the nitrogen *** temperatures of 11℃–15℃,the NLR of the system is controlled below 0.5 kg/(m^(3)·day),which can achieve stable nitrogen removal and the nitrogen removal efficiency can reach above 96%.The abundance of Candidatus Brocadia gradually increased with the decrease of ***,Candidatus Brocadia and Candidatus Kuenenia as the main functional microorganisms in the low temperature.

Automatic generation of optical initial configuration based on Delano diagram

引用

Research in Astronomy and Astrophysics 2016年第1期16卷 59-66页

作者： Kai-yuan Zhang Xiang-yan yuan Xiang-Qun Cui National Astronomical Observatories/Nanjing Institute of Astronomical Optics & Technology Nanjing 210042 China Key Laboratory of Astronomical Optics & Technology Nanjing Institute of Astronomical Optics & Technology Chinese Academy of Sciences Nanjing 210042 China University of Chinese Academy of Sciences Beijing 100049 China

This paper presents a method to automatically initialize an optical system based on the Delano diagram. The process to generate the optical initial configuration is constrained by the control points, which are deduced from parameters related to basic design requirements. We present the theory and method to generate the optical initial configuration automatically when the basic design requirements are known. Two optical systems are taken as examples to demonstrate the proposed method.

Recent advances in molecular biology research of a rice pest, the brown planthopper

引用

Journal of Integrative Agriculture 2019年第4期18卷 716-728页

作者： BAO yan-yuan ZHANG Chuan-xi State Key Laboratory of Rice Biology and Ministry of Agriculture Key Lab of Molecular Biology of Crop Pathogens and Insects Institute of Insect Sciences Zhejiang University

The brown planthopper, Nilaparvata lugens St?l, has become a major threat in tropical Asian and China since the rice green revolution of the 1960 s. Currently, insecticide application remains the primary choice for controlling this rice insect pest, but heavy use of insecticides poses dangerous risks to beneficial natural enemies and pollinators, and stimulates N. lugens reproductivity, and has caused a resurgence of the pest in the major rice-planting regions throughout Asia. Achieving the long-lasting goal of sustainable management of N. lugens requires understanding of the molecular basis of outbreaks of the pest and the development of environment-friendly pest-control strategies. Here, we review the recent molecular advances in N. lugens research on the aspects of its endosymbionts, virus transmission, insecticide resistance, and interaction between N. lugens and rice plants. We also put forward further research directions that may shed some lights on management of the rice pest.

An efficient way to enhance the total nitrogen removal efficiency of the Anammox process by S^0-based short-cut autotrophic denitrification

引用

Journal of Environmental Sciences 2019年第7期31卷 214-224页

作者： Fangmin Chen Xiang Li yan yuan Yong Huang School of Environmental Science and Engineering Suzhou University of Science and Technology National and Local Joint Engineering Laboratory of Municipal Sewage Resource Utilization Technology

In order to reduce the amount of NO_3^-–N generated by the Anammox process, and alleviate the competition between denitrification and Anammox for NO_2^-–N in a single reactor, the preference of S^0 for reacting with coexisting NO_2^-–N and NO_3^-–N in the sulfur autotrophic denitrifying(SADN) process and the coupling effect of short-cut SADN and the Anammox process were studied. The results showed that S^0 preferentially reacted with NO_3^-to produce NO_2^-–N, and then reacted with NO_2^-–N when NO_3^-–N was insufficient, which could effectively alleviate the competition between SADN bacteria(SADNB) and Anammox bacteria(An AOB) for NO_2^-–N. After 170 days of operation, coupling between short-cut S^0-SADN and the Anammox process was first successfully achieved. SADNB converted the NO_3^-–N generated by the Anammox process into NO_2^-–N, which was once again available to An AOB. The total nitrogen removal efficiency eventually stabilized at over 95%, and the effluent NO_3^-–N was controlled within 10 mg/L, when high NH_4^+–N wastewater was treated by the Anammox process. Microbial community analysis further showed that Candidatus Brocadia and Thiobacillus were the functional microorganisms for An AOB and SADNB.

作者： Su yuan Zhou Xiao yan Wei Department of Biomechanlcs Shanghai University of Sports Shanghai 200438 China

^1H NMR has been used to determine the 2-, 4-vinyl orientation of heme active site from oxidized mouse neuroglobin （mNgb）. The NOEs between 3-methyl and Hα, Hβ of 2-vinyl, together with the NOEs between 5-methyl and Hα, Hβ of 4-vinyl, allowed the unambiguous determination of trans and cis orientations for the 2- and 4-vinyl groups in the mNgb, respectively.

Low-lying electronic states of aluminum monoiodide

引用

Chinese Physics B 2019年第4期28卷 150-156页

作者： Xiang yuan Shuang Yin Yi Lian Pei-yuan yan Hai-Feng Xu Bing yan Jilin Provincial Key Laboratory of Applied Atomic and Molecular Spectroscopy (Jilin University) Institute of Atomic and Molecular PhysicsJilin University

High-level ab initio calculations of aluminum monoiodide(AlI) molecule are performed by utilizing the multireference configuration interaction plus Davidson correction(MRCI+Q) method. The core-valence correlation(CV) and spin–orbit coupling(SOC) effect are considered. The adiabatic potential energy curves(PECs) of a total of 13 Λ–S states and 24 ? states are computed. The spectroscopic constants of bound states are determined, which are in accordance with the results of the available experimental and theoretical studies. The interactions between the Λ–S states are analyzed with the aid of the spin–orbit matrix elements. Finally, the transition properties including transition dipole moment(TDM),Frank–Condon factors(FCF) and radiative lifetime are obtained based on the computed PEC. Our study sheds light on the electronic structure and spectroscopy of low-lying electronic states of the AlI molecule.
