The surface of mountain glaciers is a place accumulation various biogenic organomineral and mineral compounds. As result intensive mass deglaciation due to climate change anthropogenic activity, this material can significantly affect the transformation landscape in periglacial zone. Thus, work considers contamination Arctic, Antarctic, Caucasian by priority pollutants. Atomic absorption spectro...

We propose a method for selecting edges in Gaussian graphical models. Our algorithm takes after our previous work, an extension of Least Angle Regression (LARS), and it is based on the information geometry of dually flat spaces. Non-diagonal elements of the inverse of the covariance matrix, the concentration matrix, play an important role in edge selection. Our iterative method estimates these ...

in this study, effect of irrigation duration on concentration of some macro and micro nutrient elements in ‘thompson navel’ orange leaves grafted on three rootstocks was evaluated as a factorial experiment in completely randomized block design. factors included rootstocks in three levels (poncirus trifoliata, citrus aurantium and troyer citrange (citrus sinensis ´ poncitus trifoliata)) and irri...
