| 1 | 采用意大利多中心前瞻性研究以评估16层及64层MDCT对计划行冠状动脉造影病人的阴性预测值(NIMISCAD-意大利冠心病无创性多中心性研究)显示文摘这是一项多中心的前瞻性研究.通过应用不同制造商生产的MDCT设备,对计划行选择性冠状动脉造影(CA)的病人行MDCT检查以对其诊断冠心病(CAD)的价值进行评估。2004年7月-2006年6月间.在20所国家医院前瞻性地征集了367例病人。对于每种类型的MDCT(≥16层),CT检查均采用标准化/优化的扫描方案,并且与2周内进行的定量冠状动脉造影比较。共有284例病人(81%)应用16层MDCT进行检查,66例病人(19%)应用64层MDCT进行检查。初步分析采用院内/院外的方法,评估对1例病人的阴性预测值(NPV)。 | R.

| 2 | Height-to-diameter ratios with temporal and dendro/morphometric variables for Brazilian pine in south Brazil显示文摘Height-to-diameter ratios(HD)are an important measure of the stability,density and competition of forest stands.It refl ects the vertical growth of the trees,the vulnerability of the forest canopy structure and infl uences volumetric production.HD ratios vary according to tree size,availability of resources for growth,stand density and species composition.Data were taken from 210 trees and a regression technique of generalized linear models for the HD ratio applicable for forest structure conservation was developed.The objective of this study was to model the HD ratios of dominant and co-dominant trees of Araucaria angustifolia according to morphometric,dendrometric,annual diameter increment,stand density,and age variables in three sites in southern Brazil.The results show that the HD ratio decreases with increasing age,crown area and basal area,and increases with stand density and annual diameter increment.Accuracy of the developed equations was demonstrated by the values of deviation,Bayesian and Akaike criteria.The results are of interest to forest managers since they make decisions about silvicultural operations.Growth continuity and forest production indicate that any intervention should be directed at younger trees of smaller sizes,and that one of the main management factors for stand stability and growth is the formation of the stand and its capture of light. | Andre Felipe Hess Myrcia Minatti Emanuel Arnoni Costa Luis Paulo Baldissera Schorr Gabriel Teixeira da Rosa Isadora de Arruda Souza Geedre Adriano Borsoi Veraldo Liesenberg Thiago Floriani Stepka Roberta Abatti | 2021 | Journal of Forestry Research2021，32，1： | 2 |
