The paper describes a method for identification of mechanisms and process trends based on combination of subject-driven document clustering, shape analysis, trends understanding and relevant context retrieval via semantic analysis. The goal is to extract potentially interesting knowledge from a set of technical information based on analysis of graphical information in order to find explanation ...

Introduction: Most of previous studies on dyslipidemia among pilots were cross-sectional surveys which cannot explore the temporal trend of dyslipidemia, and these studies were normally conducted at least five years ago. In addition, studies focusing on pilots in Southwest China are scarce. This study aimed to describe the prevalence of and trends in dyslipidemia among pilots f...

temperature and precipitation are among important atmospheric parameters for watershed planning. assessment of temperature and precipitation trends is very important for future watershed planning. in this paper, trends of atmospheric parameters such as seasonal and annual temperature and precipitation were examined for the synoptic stations of bandar anzali, rasht, ramsar, babolsar and gorgan. ...

introduction two main principal aspects for the genesis of porphyry copper deposits have been determined. the first genetic model concerns the petrologic and geochemical processes and the other relates the genesis to crustal deformation and geodynamic conditions (kesler, 1997). recent studies (e.g., padilla garza et al., 2001) show that the generation and emplacement of porphyry copper deposits...

conclusions overall, cancer incidence rates had increased in both sexes. many factors were responsible, such as changes in lifestyle, environmental factors, increased life expectancy, improvements in the registration systems, and declining mortality rates due to early detection and treatment. the results of this study provided useful information for the prediction of changes in the incidence an...
