The following study uses a systematic content analysis of 100 top-rated U.S. children＇s television programs to explore the tangential relationship （i.e., distance） of narrative and educational content through the lens of the capacity model--which is built upon three basic components： narrative content, educational content, and the distance between them. Programs were analyzed for distance by examining lesson clarity and integration, show type, target audience age, and station type. One-way ANOVAs indicates significant differences between the means of these variables. Programs targeting younger children presented educational content that was closely integrated into the plotline of the program and helped further the story. However, as the target audience aged, the educational content became more tangential to the narrative content and was less tied to the plotline of the program.展开更多

Methods The lung-to-liver intensity ratio was calculated by means of region-of-interest analysis in all 35 fetuses including 7 bilateral urinary anomalies, 9 unilateral urinary anomalies, 5 pulmonary anomalies, and 14 others. Results All fetuses with urinary anomalies and pulmonary anomalies showed low ratio of lung-to-liver signal intensity. Conclusion Low ratio of lung-to-liver signal intensity on MR imaging indicates pulmonary hypoplasia after 22 weeks’ gestation.展开更多

The method consists in comparing electromagnetic compatibility （EMC） test severities to NEMP conducted stresses. The comparison uses five characteristic criteria of the induced stresses, calculated with an analytic method. The process is based on a software named ＂SUSIE＂ （in French： SUSceptibilite a I＇IEMN ＂Impulsion ElectroMagnttique d＇origine Nucl6aire Haute Altitude＂）. Today, only conducted stresses are analyzed. An evolution is planned in 2013 to determine the equivalent vulnerability of radiated stresses and to validate the software.展开更多
