Apr 30, 2010 - The correlation between repeated thinning rate measurements was modest, but repeatability was considerably more significant when analyzed in terms of the slow/rapid dichotomy. Wilcox contributed his knowledge of disease ecology and the history of ecological theory and concepts, and their application. And thinning rates differed significantly from those of a normal distribution, nonparametric statistics (Wilcoxon signed ranks test, Spearman correlation, McNemar test, and Fisher exact test, all as two-sided tests) were used for data analysis. This paper presents four This demand for creative engagement poses significant experimental and theoretical challenges for the memory institutions and the storehouse of cultural archives (Del Favero et al. May 18, 2014 - We borrow from the concept of network dramaturgies to help illustrate this compositional approach, and suggest that the use of conceptual metaphors – particularly that of a network window – can lead to meaningful dialogues between the work and the medium. Mar 13, 2009 - Ecosystems can be analyzed according to the organization of system elements and interactions, relative to defined scales, and this has proven useful in understanding natural ecosystems and the idea of nested hierarchies 36,40,41. Mar 16, 2011 - In addition, the opportunities offered by interactive 3D technologies in combination with visual analytics for enhanced cognitive exploration and interrogation of rich multimedia data still need to be realized within the domain of the digital humanities. Oct 19, 2013 - A team at the University of Calgary has assessed the thermal efficiencies, energy balances, and emissions of Steam-Assisted Gravity Drainage (SAGD)—both theoretically and as deployed at scale, using field data from the ERCB—for the . Apr 13, 2011 - This is the idea that when new theories are constructed, the central explanatory concepts of the old theory often change their meaning, so that a claim made before and after a paradigm shift, even if it uses the same words, may not express the . A compositional based model for the tear film lipid layer. The analysis shows that although some SAGD operations are achieving good steam-to-oil ratios, many are not achieveing thermally efficient operation, with cumulative steam-to-oil ratios many times the theoretical vallue. Feb 10, 2014 - Research and theory in public health and the social sciences posit that there are multiple potential pathways through which social factors determine health outcomes and urge that analyses address macroeconomic and macrosocial factors .. This type of organization occurs as a result of asymmetric system .. Keywords These initiatives share a remarkable awareness of the formal attributes of the medium they operate in, exploring, respectively, attributes of data circulation and distributed collaboration over computer networks.
