Storage The main research problem of the paper is aimed at determining the proper functioning of Lake Gardno within the period 2012-2014 considered as hydrological years in reference to the physiochemical properties of its waters, water balance, thermal regime and water overturn.Lake Gardno is a representative of non-run-off lake geo-eco-systems; i
Simple approximations for the ruin probability in the risk model with stochastic premiums and a constant dividend strategy
We deal with a generalization of the risk model with stochastic premiums where Braces dividends are paid according to a constant dividend strategy and consider heuristic approximations for the ruin probability.To be more precise, we construct five- and three-moment analogues to the De Vylder approximation.To this end, we obtain an explicit formula
Morphological and structural aspects of the extremely halophilic archaeon Haloquadratum walsbyi.
Ultrathin square cell swim tank Haloquadratum walsbyi from the Archaea domain are the most abundant microorganisms in the hypersaline water of coastal salterns and continental salt lakes.In this work, we explore the cell surface of these microorganisms using amplitude-modulation atomic-force microscopy in nearly physiological conditions.We demonstr
DFT studies of the copper active site in AA13 polysaccharide monooxygenases
AA13 polysaccharide monooxygenases (AA13 PMOs) are novel enzymes that break down starch using a copper active site in a substrate binding groove on a solvent-exposed surface.The structure of the copper active site is influenced by the residues in the groove, while the crystal structure of Cu(II)-AA13 was damaged by photoreduction and lacked two exo
