Interactions between polar bears (Ursus maritimus) and humans in 6 national parks in the Canadian Arctic from 1986 to 2000 were examined (n = 53). No human fatalities and only 1 injury occurred. Bears were killed in only 4% of interactions, a much lower rate than in other studies, possibly because of the availability of deterrents. Interactions occurred mainly in summer in parks where bears are...

The variance components models for gene-environment interaction proposed by Purcell in 2002 are widely used. In both the bivariate and the univariate parameterization of these models, the variance decomposition of trait T is a function of moderator M. We show that if M and T are correlated, and moderator M is correlated between twins as well, the univariate parameterization produces a considera...

The paper discusses two body-language humancomputer interaction modalities, namely facial expressions and hand gestures, for healthcare and smart environment

dynamic analysis and study of atomic force microscope in liquid environment is the main goal of this research. hydrodynamic and squeeze forces act on cantilever of atomic force microscope which works in liquid environment, so. in this paper the effect of different environmental and physical factors had studied on frequency response diagrams. the importance of frequency response analysis is stud...

yield stability of 17 genotypes including eight of tritipyrum lines, five promising triticale lines and four iranian bread wheat varieties were studied in a randomized completely block design with three replications in seven environment during growing seasons of 2001-2002, 2002-2003, 2005-2006 and 2010-2011 in three locations. analysis of additive main effects and multiplicative interaction eff...
