Chlorophyll «a» concentration in the South-Eastern Baltic Sea in summer 2018 (on satellite data)
The study focuses on chlorophyll "a"concentration variability in the South-Eastern part of the Baltic sea in summer 2018. The data of the MODIS radiometer installed on Aqua and Terra satellites were used for the analysis. The average concentration of chlorophyll "a" in the warm ...
Simulating of non-stationary processes in the ionospheric plasma
A model of distribution of concentration, velocities and temperatures of ions along a geomagnetic flux tube is considered. The model also examines the main processes of chemical kinetics, ambipolar diffusion, influence of horizontal neutral wind and plasma heating by superthermal ...
An oscillatory excited molecular nitrogen in the ionospheric plasma
... to investigate dynamics of interaction charged and neutral components of ionospheric plasma, and also to reveal a contribution of various processes to formation of ionosphere. Results of computing experiment indicate strong dependence of electronic concentration on high-rise distribution of nitrogen. The accounting of oscillatory excitement of molecular nitrogen leads to noticeable variations of electronic concentration and temperature at ionosphere F2 layer heights and improves a consent of results ...
Distribution of heavy metals in the soils and vegetation in urban ecosystems of Kaliningrad region
Some peculiarities of heavy metals concentrations in the accumulating layer of the urban soils and leafs of Acer platanoides and Populus alba are presented. Dependence between physical and chemical features, geochemical structure of landscapes, concentration and distribution of heavy metals ...
The influence of latitudinal gradient on sugar concentration in the nectar of Taraxacum officinale Wigg.
This article analyses the dynamics of sugar concentration in the nectar of Taraxacum officinale Wigg. in the arctic, boreal and temperate zones of Russia. The author arrives at the conclusion that the sugar productivity of flowers analysed changes throughout the day. The average sugar production ...

Computer simulation of synthesis processes in NiO—Al system
Features of physical and chemical conversions in the reacting powder system NiO-Al were investigated by computer simulation methods.. Multivariability of the synthesis of nickel aluminides in powder systems with varying degrees of concentration inhomogeneity is taken into account. The estimates of the state parameters of reacting system at all stages of physical and chemical transformations was obtained.
Reaction mechanism for thermite combustion synthesis ...
