Windthrow problem is a difficult task for the forest managers in the Romanian Carpathians and especially in Iezer Mountains. The last windthrow, in July 2005, affected about 370 ha within the study area and left unprotected large slopes with important declivities （20-30°）. In our study, we try to propose a tool for forest management, in order to control and minimize the negative effect of wind upon the mountain forest ecosystem. The digital data input derived from forestry data （forest stand typology, age, canopy coverage index, forest productivity class） and from the forest biotope features （soil and topography parameters）. The main goal was to find a more objective way for digital layer reclassification in order to obtain the windthrow areas susceptibility map for the Iezer Mountains. Each digital layer has its own weight within the analysis and one of them was difficult to be modeled （the wind features）. A statistical approach was developed on the basis of local phenomena and the wind- throw features in the Romanian Carpathians. This allowed us to obtain the reclassification conditions for each digital layer. Forest canopy typology and soil features （mainly its volume） were considered as the key factors for the windthrow occurrence analysis. The final windthrow susceptibility map was validated with the help of the statistic occurrence of windthrow areas within each susceptibility class and after a field check of the sites. The result was encouraging, because 92.5% of the windthrow areas fall into the highest windthrow susceptibility class.

BACKGROUND Many scores have been suggested to assess the severity of acute pancreatitis upon *** extrapancreatic necrosis volume is a novel,promising score that appears to be superior to other scores investigated so *** To evaluate the discriminatory power of extrapancreatic necrosis volume to identify severe cases of acute *** A total of 123 patients diagnosed with acute pancreatitis at Institute of Gastroenterology and Hepatology,St Spiridon Hospital between January 1,2017 and December 31,2019 were analyzed *** was classified according to the revised Atlanta classification(rAC)as mild,moderate,or *** was also evaluated by computed tomography and classified according to the computed tomography severity index(CTSI)and the modified CTSI(mCTSI).The results were compared with the extrapancreatic volume necrosis to establish the sensitivity and specificity of each *** The CTSI and mCTSI imaging scores and the extrapancreatic necrosis volume were highly correlated with the severity of pancreatitis estimated by the rAC(r=0.926,P<0.001 and r=0.950,P<0.001;r=0.784,P<0.001,respectively).The correlation of C-reactive protein with severity was positive but not as strong,and was not significant(r=0.133,P=0.154).The best predictor for the assessment of severe pancreatitis was the extrapancreatic necrosis volume[area under the curve(AUC)=0.993;95%confidence interval(CI):0.981-1.005],with a 99.5%sensitivity and 99.0%specificity at a cutoff value of 167 mL,followed by the mCTSI 2007 score(AUC=0.972;95%CI:0.946-0.999),with a 98.0%sensitivity and 96.5%specificity,and the CTSI 1990 score(AUC=0.969;95%CI:0.941-0.998),with a 97.0%sensitivity and 95.0%*** Radiological severity scores correlate strongly and positively with disease *** necrosis volume shows the best diagnostic accuracy for severe cases.

Paleosols from North Part of Barlad City （Romania）

Journal of Earth Science and Engineering 2012年第2期2卷 71-76页

作者： Daniel Bejan bogdan Gabriel Ratoi mihai Branzila Department of Geology Faculty of Geography and Geology Alexandru loan Cuza University of lasi Iasi 700505 Romania

The loess deposits comprise several paleosol layers reflecting alternation of drier and wetter climate during Quaternary. Such a situation occurs in north of Barlad, on The Sohodau＇s Hill. Morphological study of the quarry paleosols from north of Barlad was accomplished based on field observations and macroscopic physic-chemical results. Three levels of paleosols with variable thickness were determined. These three fossils layers are interbedded by four loess deposits. The physical-chimical data provide important information for the paleosol genesis and depositional/climatic environments. The carbon content and C/N ratio indicate the strength of pedogenesis in the Pleistocene and trends of biomass accumulation.
