Analysis of the physiological responses of the plane and willow trees against air pollution in Tehran .
Trees can improve air quality, but at the same time, pollution might put them at risk. Plane(Platanus orientalis L) and willow trees (Salix babylonicaL) are important trees in the green space of Tehran. Plane trees in Tehran have experienced early autumn in recent years due to severe air pollution. The present study, investigated some physiological traits of these trees under study to determine...
متن کاملConcentration of Heavy Metals in Bark Samples of Pine Trees in Neishabur, Iran
Background and purpose: Heavy metals in urban air are major health threats and increase the risk of respiratory, cardiovascular, and cancers in humans. An efficient and low-cost method for monitoring these pollutants is using tree bark as a bioindicator. The purpose of this study was to measure the concentration of heavy metals by pine tree bark as a bioindicator in Neishabur, north-east of Ira...
متن کاملFactors Influencing Drug Injection History among Prisoners: A Comparison between Classification and Regression Trees and Logistic Regression Analysis
Background: Due to the importance of medical studies, researchers of this field should be familiar with various types of statistical analyses to select the most appropriate method based on the characteristics of their data sets. Classification and regression trees (CARTs) can be as complementary to regression models. We compared the performance of a logistic regression model and a CART in predi...

متن کاملEvaluating techniques for generating metric-based classification trees
Metric-based classi cation trees provide an approach for identifying user-speci ed classes of high-risk software components throughout the software lifecycle. Based on measurable attributes of software components and processes, this empirically guided approach derives models of problematic software components. These models, which are represented as classi cation trees, are used on future system...
