Measurements of 137Cs body burden were carried out in 1991-1996 for children residing in the western part of Bryansk Oblast (Russia) where area contamination with 137Cs following the Chernobyl accident varied from 0.03-3.7 MBq m(-2). The mean and median values of 137Cs specific activity (SA) in the bodies of children 5-15 y old for the whole period of(More)
Changing ocean health and the potential impact on marine mammal health are gaining global attention. Direct health assessments of wild marine mammals, however, is inherently difficult. Breath analysis metabolomics is a very attractive assessment tool due to its noninvasive nature, but it is analytically challenging. It has never been attempted in cetaceans(More)
The influence of the historical exploitiation and recovery of biological resources on populations of freshwater pearl mussel and salmon was studied in the Kozha river (Onega River Basin). The freshwater pearl mussel was characterized by a low population density (0.09 ind./m2, on the average) and number of recruits. The role of the anthropogenic factor in(More)

The proposed fluid-structure interaction (FSI) approach is based on a two-way coupling between finite-element code Abaqus and finite-volume code FlowVision. The FSI simulation is possible due to a unique mesh generation method used in FlowVision. The method is called SubGrid Resolution Method (SGRM). The SGRM connects seamlessly FE and CFD meshes without(More)
Synthesis of grafted copolymers of sodium lignosulfonate with methyl acrylate was performed by means of radical (co)polymerization. Mechanism of grafted radical (co)polymerization was proposed on the basis of IR spectroscopy data and functional analysis. Polyelectrolyte, hydrodynamic, polymolecular, and surfactant properties of water-soluble grafted(More)
