| 1 | Estimation of ammonia nitrogen load from nonpoint sources in the Xitiao River catchment, China显示文摘Ammonia nitrogen (NH4+-N) is one of the three main forms of total nitrogen (TN). Most studies have estimated the load of TN from nonpoint sources instead of one specific form. The relationship between land use and concentrations of NH4+-N in runoff was analyzed using the hydraulic analysis functions of a Geographic Information Systems (GIS), and the annual loads of NH4+-N in the Xitiao River catchment were estimated according to model results. The results suggested that the calculated annual loads of NH4+-N agreed well with the observed ones, which was a good example demonstrating that it was possible to estimate the pollutant loads from nonpoint sources without enough monitoring data. Results also showed that the concentrations of NH4+-N in river waters of forest and arable land in the study area were 0.16 and 0.39 mg/L, respectively. The total nonpoint source load of NH4+-N from 1995 to 2001 (except 1998 and 2000) varied between 2,098 and 7,992 tons/year in the Xitiao River catchment. | Tao LIANG Zhongyi CHONG | 2008 | Journal of Environmental Sciences2008，20，10： | 13 |
| 2 | Dry Sliding Tribological Properties of a Dendrite-reinforced Zr-based Bulk Metallic Glass Matrix Composite显示文摘In-situ dendrite-reinforced metallic glass matrix(MGM) composites with the composition of Zr58.5Ti14.3Nb5.2Cu6.1Ni4.9Be11.0were prepared with a vacuum arc melter by the copper mold suction casting.Effect of different normal loads and sliding velocities on the tribological properties of MGM composites was studied. The results showed that the friction coefficient and wear rate of composites initially descended with increasing the normal load and reached a minimum of 0.339 and 1.826 10 4mm3/(N m) at 10 N,respectively, then ascended. Similarly, the friction coefficient and wear rate of composites initially decreased with the increase in the sliding velocity and reached a minimum of 0.330 and 2.389 10 4mm3/(N m) at0.4 m/s and 0.3 m/s, respectively, then raised. The wear mechanism of composites was mainly adhesive wear accompanied by abrasive wear at lower normal load and sliding velocity. However, the wear mechanism of composites was abrasive wear and adhesive wear as well as delamination at higher normal load and sliding velocity due to the nucleation and propagation of surface and subsurface cracks during the wear process. The flake-like and particle-like wear debris was the dominant shapes of debris observed. | Huijun Yang Yong Liu Teng Zhang Hengpeng Wang Bin Tang Junwei Qiao | 2014 | Journal of Materials Science & Technology2014，30，6： | 4 |

| 10 | Effects of different cooking methods on peanut allergenicity显示文摘Peanut allergy is a type of serious food allergy worldwide.In this study,peanuts were treated with two different cooking methods.The effect of cooking on digestion stability was evaluated by simulated gastrointestinal digestions.The effects of cooking on the allergenicity were assessed by immunoblotting,passive cutaneous anaphylaxis (PCA) mice model and rat basophilic leukemia (RBL)-2H3 cell model.Results showed that raw peanuts were more stable to digestion than boiled and fried peanuts.SDS-PAGE showed that the quantities of allergens Ara h 1 (64 kDa),Ara h 2 (20 kDa),and Ara h 3 (38 kDa) in the boiled and fried peanuts were all reduced.Meanwhile,immunoblotting revealed the IgE binding capacities of boiled and fried peanuts were decreased significantly,especially the fried peanuts.In the PCA mice model,the vascular permeability of allergic mice,as well as the release of histamine,were both alleviated in mice gavaged with boiled and fried peanuts compared with raw peanuts.Lastly,the release of β-hexosaminidase of RBL-2H3 cells treated with boiled and fried peanuts was significantly decreased compared with the raw peanuts.In addition,the analyses of circular dichroism (CD) spectra showed that the α-helical content of peanut proteins was decreased after boiling and frying,indicating the structure stability of peanut allergens decreased.The analyses of ultraviolet (UV) spectra showed that aromatic amino acid residues were exposed,causing the change of the tertiary structure of peanut allergens after boiling and frying.In conclusion,the allergenicity of peanuts was significantly reduced after boiling and frying,especially frying. | Tao Wang Yutong Huang Xinlei Tang Hengpeng Wang Bing Li Xiangren Meng Songsong Jiang | 2022 | Food Bioscience2022，47，3： | 1 |

| 19 | Sensitivity of Near Real-time MODIS Gross Primary Productivity in Terrestrial Forests Based on Eddy Covariance Measurements显示文摘As an important product of Moderate Resolution Imaging Spectroradiometer(MODIS), MOD17A2 provides dramatic improvements in our ability to accurately and continuously monitor global terrestrial primary production, which is also significant in effort to advance scientific research and eco-environmental management. Over the past decades, forests have moderated climate change by sequestrating about one-quarter of the carbon emitted by human activities through fossil fuels burning and land use/land cover change. Thus, the carbon uptake by forests reduces the rate at which carbon accumulates in the atmosphere. However, the sensitivity of near real-time MODIS gross primary productivity(GPP) product is directly constrained by uncertainties in the modeling process, especially in complicated forest ecosystems. Although there have been plenty of studies to verify MODIS GPP with ground-based measurements using the eddy covariance(EC) technique, few have comprehensively validated the performance of MODIS estimates(Collection 5) across diverse forest types. Therefore, the present study examined the degree of correspondence between MODIS-derived GPP and EC-measured GPP at seasonal and interannual time scales for the main forest ecosystems, including evergreen broadleaf forest(EBF), evergreen needleleaf forest(ENF), deciduous broadleaf forest(DBF), and mixed forest(MF) relying on 16 flux towers with a total of 68 site-year datasets. Overall, site-specific evaluation of multi-year mean annual GPP estimates indicates that the current MOD17A2 product works highly effectively for MF and DBF, moderately effectively for ENF, and ineffectively for EBF. Except for tropical forest, MODIS estimates could capture the broad trends of GPP at 8-day time scale for all other sites surveyed. On the annual time scale, the best performance was observed in MF, followed by ENF, DBF, and EBF. Trend analyses also revealed the poor performance of MODIS GPP product in EBF and DBF. Thus, improvements in the sensitivity of MOD17A2 to forest productivity require continued efforts. | TANG Xuguang LI Hengpeng LIU Guihua LI Xinyan YAO Li XIE Jing CHANG Shouzhi | 2015 | Chinese Geographical Science2015，25，5： | 1 |
