| 1 | Effect of rare-earth oxides on properties of silicon nitride obtained by normal sintering and sinter-HIP显示文摘This paper presented the microstructure,mechanical properties and oxidation behavior of silicon nitride obtained by both conventional sintering and sintering followed by hot isostatic pressing(HIP).Silicon nitride with additives such as 5 wt.% Al2O3 and 5 wt.% Ln2O3(Ln= La,La concentrate,Gd or La+Gd) were studied.The results revealed that Gd2O3 additions increased the formation of elongated grains of β-Si3N4,the fracture toughness and oxidation resistance.La2O3 additions led to higher densification and hardness values,while addition of La2O3 concentrate promoted the formation of materials with intermediate properties,compared to the other studied compositions.Hot isostatic pressing increased the hardness but decreased the fracture toughness of the material,mainly because it allowed residual pores to close and also reduced the average aspect ratio of β-Si3N4 grains. | Cecilia C.Guedes-Silva Flávio Machado de Souza Carvalho José Carlos Bressiani | 2012 | Journal of Rare Earths2012，30，11： | 4 |

| 19 | Effects of spatial and temporal weather data resolutions on streamflow modeling of a semi-arid basin,Northeast Brazil显示文摘One major difficulty in the application of distributed hydrological models is the availability of data with sufficient quantity and quality to perform an adequate evaluation of a watershed and to capture its dynamics.The Soil&Water Assessment Tool(SWAT)was used in this study to analyze the hydrologic responses to different sources,spatial scales,and temporal resolutions of weather inputs for the semi-arid Jaguaribe watershed(73000 km2)in northeastern Brazil.Four different simulations were conducted,based on four groups of weather and precipitation inputs:Group 1-SWAT Weather Generator based on monthly data from four airport weather stations and daily data based on 124 local rain gauges;Group 2-daily local data from 14 weather stations and 124 precipitation gauges;Group 3-Daily values from a global coupled forecast model(NOAA’s Climate Forecast System Reanalysis-CFSR);and Group 4-CFSR data with 124 local precipitation gauges.The four simulations were evaluated using multiple statistical efficiency metrics for four streamflow gauges,using:Nash-Sutcliffe coefficient(NSE),determination coefficient(R2),the ratio of the root mean square to the standard deviation of the observed data(RSR),and the percent bias(PBIAS).The Group 4 simulation performed best overall(provided the best statistical values)with results ranked as“good”or“very good”on all four efficiency metrics suggesting that using CFSR data for weather parameters other than precipitation,coupled with precipitation data from local rain gauges,can provide reasonable hydrologic responses.The second best results were obtained with Group 1,which provided“good”results in three of four efficiency metrics.Group 2 performed worse overall than Groups 1 and 4,probably due to uncertainty related to daily measures and a large percentage of missing data.Groups 2 and 3 were“unsatisfactory”according to three or four of the efficiency metrics,indicating that the choice of weather data is very important. | Danielle de Almeida Bressiani Raghavan Srinivasan Charles Allan Jones Eduardo Mario Mendiondo | 2015 | International Journal of Agricultural and Biological Engineering2015，8，3： | 1 |
