1Effects of elevated CO_2 on the nutrient compositions and enzymes activities of Nilaparvata lugens nymphs fed on rice plants显示文摘Elevated CO 2 may reduce the tolerance of Nilaparvata lugen (N. lugens) to adverse environmental factors through the biological and physiological degeneration of N. lugens. In an artificial climate box, under 375 and 750 μL L 1 CO 2 levels, the rice stems nutrient content, the nutrient content and enzyme activities of N. lugens nymph fed on rice seedlings exposed to ambient and elevated CO 2 were studied. The results showed that rice stems had significantly higher protein and total amino acid levels under ambient than elevated CO 2 levels. Nymphs had significantly higher protein levels in the ambient CO 2 treatment, while their glucose levels were significantly lower under ambient CO 2 conditions. Significantly higher trypsin activity was observed in nymphs grown in elevated CO 2 . Significantly lower activities of the protective enzymes total superoxide dismutase and catalase were observed in the nymphs under ambient CO 2 . Meanwhile, the activity of the detoxification enzyme glutathione S-transferase was significantly higher in the ambient CO 2 treatment. Measuring how energy and resources were allocated to enzymes in N. lugens nymphs under elevated CO 2 conditions can provide a more meaningful evaluation of their metabolic tolerances to adverse climatic conditions.ZENG YunYun HUANG WenKun SU Li WU Gang ZHUANG Jing ZHAO WanYun HUA HongXia LI JunSheng XIAO NengWen XIONG-YanFei 2012Science China(Life Sciences)2012,55,10:7

6Polymer-derived SiBCN ceramic pressure sensor with excellent sensing performance显示文摘Pressure measurement with excellent stability and long time durability is highly desired,especially at high temperature and harsh environments.A polymer-derived silicoboron carbonitride(SiBCN)ceramic pressure sensor with excellent stability,accuracy,and repeatability is designed based on the giant piezoresistivity of SiBCN ceramics.The SiBCN ceramic sensor was packaged in a stainless steel case and tested using half Wheatstone bridge with the uniaxial pressure up to 10 MPa.The SiBCN ceramic showed a remarkable piezoresistive effect with the gauge factor(K)as high as 5500.The output voltage of packed SiBCN ceramic sensor changes monotonically and smoothly versus external pressure.The as received SiBCN pressure sensor possesses features of short response time,excellent repeatability,stability,sensitivity,and accuracy.Taking the excellent high temperature thermo-mechanical properties of polymer-derived SiBCN ceramics(e.g.,high temperature stability,oxidation/corrosion resistance)into account,SiBCN ceramic sensor has significant potential for pressure measurement at high temperature and harsh environments.Gang SHAO Junpeng JIANG Mingjie JIANG Jie SU Wen LIU Hailong WANG Hongliang XU Hongxia LU Rui ZHANG 2020Journal of Advanced Ceramics2020,9,3:3
7Preparation of SiC Porous Ceramics by Crystalline Silicon Cutting Waste显示文摘SiC porous ceramics were prepared at 1 400 ℃ for4 h with crystalline silicon cutting waste and activated carbon as main starting materials and NH_4HCO_3 as the pore-forming agent. Effects of NH_4HCO_3 additions( 0,20%,30%,40%,by mass) on the phase composition,microstructure,sintering properties,cold compressive strength and thermal shock resistance of as-prepared Si C porous ceramics were investigated. The results show that:( 1) addition of NH_4HCO_3 remarkably influences the apparent porosity and cold compressive strength of specimens. The apparent porosity achieves its maximum value( 63. 40%) when 40% NH_4HCO_3 is added,while the minimum cold compressive strength is 4. 77 MPa;( 2) the specimen with 40% NH_4HCO_3 has the best thermal shock resistance. The thermal cycling times between1 000 ℃ to room temperature reach 62;( 3) the addition of NH_4HCO_3 does not remarkably affect the phase composition of the specimens;( 4) the specimens include a large number of SiC particles and a small amount of SiC whiskers.ZHANG Yaran MA Beiyue YU Jingyu SU Chang REN Xinming QIAN Fan LIU Guoqi LI Hongxia YU Jingkun 2018China's Refractories2018,27,4:3
8Spatial distribution characteristics of bacterial community structure and gene abundance in sediments of the Bohai Sea显示文摘This study investigated differences in the community structure and environmental responses of the bacterial community in sediments of the Bohai Sea.Illumina high-throughput sequencing technology and real-time PCR were used to assay the bacterial 16S rRNA genes in the surface sediments of 13 sampling stations in the Bohai Sea.The results showed that sediments at the majority of the 13 sampling stations were contaminated by heavy metal mercury.The main phyla of bacteria recorded included Proteobacteria(52.92%),Bacteroidetes(11.76%),Planctomycetes(7.39%),Acidobacteria(6.53%)and Chloroflexi(4.97%).The genus with the highest relative abundance was Desulfobulbus(4.99%),which was the dominant genus at most sampling stations,followed by Lutimonas and Halioglobus.The main factors influencing bacterial community structure were total organic carbon,followed by depth and total phosphorus.The content of lead,cadmium,chromium,copper and zinc had a consistent effect on community structure.Arsenic showed a negative correlation with bacterial community structure in most samples,while the impact of mercury on community structure was not significant.The bacterial community in sediment samples from the Bohai Sea was rich in diversity and displayed an increase in diversity from high to low latitudes.The data indicated that the Bohai Sea had abundant microbial resources and was rich in bacteria with the potential to metabolize many types of pollutants.Quanrui Chen Jingfeng Fan Jie Su Hongxia Ming Zhihao Sun Mengfei Li Xiaohui Zhao Yantao Wang Yingxue Zhang Huizhen Zhang Yuan Jin Xiaowan Ma Bin Wang 2020Acta Oceanologica Sinica2020,39,2:2
9A mathematical modeling study of the HIV epidemics at two rural townships in the Liangshan Prefecture of the Sichuan Province of China显示文摘Background:As a response to a severe HIV epidemic in the Liangshan Prefecture,one of the worst in China,population based HIV interventions,including two population-wide HIV screening,have been carried out since 2005 at two townships in a remote mountainous region of Liangshan.The objective of our mathematical modeling study is to assess the temporal dynamics of the HIV epidemic in the two townships based on the data collected in the study area during the period 2005e2010.Methods:A mathematical model was set up to describe the population dynamics of HIV transmission in study area.The model was calibrated by fitting it to the HIV testing and treatment data from 2005 to 2008.Validation of the model was done by comparing its predicted value of HIV prevalence in 2010 to the prevalence data obtained in the 2010 population wide HIV testing.The validated model was used to produce estimation of HIV incidence,prevalence and death.Results:Our model estimations show that population-based HIV interventions have significantly slowed down the rise of the HIV epidemic in the two townships.Over the five-year period from 2005 to 2010,the year-over-year rate of increase in HIV incidence,prevalence,and death has declined by 91.5%,28.7%,and 52.3%,respectively.Conclusion:Mathematical models,when integrated with epidemiological and surveillance data,can be an effective tool for predicting the temporal dynamics of HIV and assessing the impacts of HIV interventions.Zhimin Su Caiting Dong Ping Li Hongxia Deng Yuhan Gong Shiyong Zhong Min Wu Yuhua Ruan Guangming Qin Wen Yang Yiming Shao Michael Li 2016Infectious Disease Modelling2016,1,1:2

15Effect of Surface Modifications on the Magnetic Properties of Ni_(0.5)Zn_(0.5)Fe_2O_4 Nanoparticles显示文摘Two different silica sources have been used for the preparation of Ni0.5Zn0.5Fe2O4/SiO2 nanocomposites,and their effects on the particle size,crystallinity and the magnetic properties have been investigated by Xray diffraction(XRD),transmission electron microscopy(TEM) and physical property measurement system(PPMS).In both cases,Ni0.5Zn0.5Fe2O4 nanoparticles of 11 nm in mean particle size were well dispersed in silica matrix.The coercivity and the blocking temperature of Ni0.5Zn0.5Fe2O4 nanoparticles modified with the silicon coupling agent show little decrease,whereas the saturation magnetization increases obviously with respect to nanoparticles dispersed directly in silica matrix.It is considered that the decrease of the surface anisotropy resulting from the change in the surface coordination is responsible for the observed behavior.Wei Zhang Hongxia Wang Faling Zhang Zhengnan Qian Wenhui Su 2010Journal of Materials Science & Technology2010,26,6:1
