Aerosols play an important role in the atmosphere but are poorly characterized, particularly in urban areas like the Mexico City Metropolitan Area (MCMA). The chemical composition of urban particles must be known to assess their effects on the environment, and specific particulat
Physicochemical characteristics and trophic state evaluation of post glacial mountain lake using multivariate analysis
The current study deals with the physicochemical characterization, temporal variability and trophic state evaluation of a post glacial mountain lake in eastern Himalaya during the period of 2014-2016. Notable seasonal variations are recorded for physicochemical parameters of lake
A multivariate analysis of potential risk factors for intra- and postoperative complications in 1316 elective laparoscopic colorectal procedures.
OBJECTIVE To identify predictive risk factors for intra- and postoperative complications in patients undergoing laparoscopic colorectal surgery. BACKGROUND DATA In emergency situations or in elective open and laparoscopic colorectal surgery, there are many risk factors that shoul
Multivariate analysis of correlation between electrophysiological and hemodynamic responses during cognitive processing
Animal and human studies have frequently shown that in primary sensory and motor regions the BOLD signal correlates positively with high-frequency and negatively with low-frequency neuronal activity. However, recent evidence suggests that this relationship may also vary across co
Prediction of Postoperative Mortality in Liver Transplantation in the Era of MELD-Based Liver Allocation: A Multivariate Analysis
BACKGROUND AND AIMS Liver transplantation is the only curative treatment for end-stage liver disease. While waiting list mortality can be predicted by the MELD-score, reliable scoring systems for the postoperative period do not exist. This study's objective was to identify risk f
Quantifying the Rate of Environmental Factors Effect on Astragalus verus and Agropyron trichophorum Using Decision Support System and Multivariate Analysis of PCA
Vegetation cover over time and space is the result of interactions betweenvegetation cover and environmental factors. Changes occurred in range covers are caused bymatrix dominance, one of the most important environmental factors. Decision support system(DSS) could be used for de
Risk Factors for Women to Have Urodynamic Stress Urinary Incontinence at A Turkish Tertiary Referral Center: A Multivariate Analysis Study.
PURPOSE To investigate the risk factors in women with urodynamic stress urinary incontinence (USTIC) at a Turkish tertiary referral center. MATERIALS AND METHODS The urodynamic records of 3038 consecutive women were analyzed between 1990 and 2011. The patients who had etiological

Measures of precision for dissimilarity-based multivariate analysis of ecological communities
Ecological studies require key decisions regarding the appropriate size and number of sampling units. No methods currently exist to measure precision for multivariate assemblage data when dissimilarity-based analyses are intended to follow. Here, we propose a pseudo multivariate
The influence of television and video game use on attention and school problems: a multivariate analysis with other risk factors controlled.
BACKGROUND Research on youth mental health has increasingly indicated the importance of multivariate analyses of multiple risk factors for negative outcomes. Television and video game use have often been posited as potential contributors to attention problems, but previous studie
