Testing the Modified Sediment Delivery Model (MOSEDD) at SPA2 Experimental Basin,Sicily (Italy)     

《Land Degradation \u0026amp; Development》2017,28(5):1557-1567

A new version of a spatially distributed sediment delivery model taking into account the hillslope sediment transport efficiency, named MOSEDD, is presented. This model gives estimates of basin sediment yield at event scale, which are more reliable than those obtained by the original SEDD. For SPA2 basin discretized into morphological units, four different calculation schemes of MOSEDD, including the original SEDD version, were applied. All parameterization schemes of the model were calibrated using 15 events measured at the outlet of the experimental basin in the period February 2005–February 2010. The model calibration was used to determine a relationship between the coefficient β _e of the model and the erosivity factor. For the model validation, other six measured events, collected in the period March 2010–February 2014, were used. At event scale, the comparison between measured sediment yield values and calculated ones showed that the three calculation schemes of MOSEDD using a rainfall–runoff erosivity factor (MODB, MODC and MODD) have the best performance in estimating sediment yield with respect to the original version of SEDD. The analysis was also developed at annual scale, for the period 2005–2014, and a relationship between the annual value of the coefficient, β _a , of the model and the corresponding erosivity factor was established. This last analysis showed that the sediment delivery distributed approach has also a good predictive ability at annual scale. Copyright © 2016 John Wiley & Sons, Ltd.  相似文献   

An association exists between bovine herpesvirus-4 seropositivity and abortion in cows     

G. Czaplicki  E. Thiry 《Preventive veterinary medicine》1998,33(1-4):235-240

The prevalence of cattle seropositive to bovine herpesvirus-4 (BHV-4) is high in Belgium. In Belgian farms, clinical signs associated with BHV-4 infection essentially involve the genital tract and consist mainly of postpartum metritis or metroperitonitis. The role of BHV-4 in abortion has not been definitively demonstrated but epidemiological and experimental facts suggest its involvement. A seroepidemiological investigation was therefore conducted as a case-control study to compare the seroprevalences of BHV-4 infections in the aborted-cow population and in a randomly selected control group in the province of Liège (Belgium). The seroprevalence (17.2%) in aborted cows was significantly higher than that of the control group (10.0%). The odds ratio (OR) was 1.87 (1.06 < 3.30). BHV-4 infection is therefore considered as a risk factor for abortion in cows.  相似文献   

Study on the Balanced Fertilization for Corn in Black Soil Region     

LiuDe－zhi  GaoYun 《东北农业大学学报(英文版)》1999,6(2):94-99

Regressive models were obtained by employing “311-B” and “3414” optimal regressive desingns through 5-year (1993-1997) field experiment,and by datum processing with computer.These models express the relationships between corn yields in high,middle and low yield areas and N,P,and K application rates in black soil.By analysis to the models,the fertilizer application rates for maximum yield and optimal yield were achieved.  相似文献
