Murmansk State Technical University or MSTU is one of the oldest universities on the Kola peninsula. The university was founded in 1950. Initially it had a name of the High Marine School . Later it received the status of the Russian State Academy of Fishing Fleet and since 1996 it has become the Murmansk State Technical University, the biggest and the most prestigious educational Center in the Far North of Russia and undoubtedly one of the biggest and famous in the whole North-West of the country.

This review summarises the interfacial shear rheology in the context of problems occurring during the measuring process. The main areas covered are surfactants, proteins, macromolecules, monolayers, particles or mixed systems at the gas/liquid and liquid/liquid interface. New developments in measuring techniques, in data analysis, modelling and theory will be discussed, while micro-rheological techniques using optical or magnetic tweezers are not in the scope of this contribution. © 2010 Elsevier Ltd.

Solubility was studied in the system NaCl–AlCl3–HCl–H2O at 25°C in the section 28 wt % HCl. The system is of the eutonic type and has an extensive sodium chloride crystallization region. The composition of the eutonic solution is the following, wt %: NaCl, 0.47; AlCl3 • 6H2O, 8.88; HCl, 25.38; and H2O, 65.27. The lines of saturated solutions were approximated by polynomial equations. © 2016, Pleiades Publishing, Ltd.

A mathematical modeling method and the global numerical model of the Earth's upper atmosphere were used to study nighttime enhanced electron density regions (EEDRs) in the ionospheric F2 layer and their possible manifestations at altitudes of the Earth's plasmasphere. It has been established that EEDRs are formed owing to latitudinally nonuniform longitudinal (along the magnetic field) plasma flows from the plasmasphere into the nighttime ionosphere and the wind transport of ions along geomagnetic field lines. The specific features of the effect of ionospheric-plasmaspheric plasma transport processes, related to their three-dimensional character, on EEDRs have been revealed. © 2012 Pleiades Publishing, Ltd.

This review is devoted to discussing the results of studies of the influence of low-molecular weight surfactant additions on the composition and properties of gelatin adsorbed layers which are spontaneously created at water/air and water/non-polar-liquid interfaces. The interaction of surfactant with gelatin leads to the formation of complexes of variable content in the aqueous phase bulk. The composition content is determined by the component ratio and concentration of the added surfactant. The role of surfactants (anionic, cationic, non-ionic) capable of forming complexes with gelatin due to electrostatic and hydrophobic interactions is considered. Analysis of the interfacial layer properties is based on literature information, as well as the own author's data. These data include the results of measuring thermodynamic properties (interface tension), laws of formation (adsorption kinetics and thickness), and rheological properties of the layers, which are considered to be dependent on gelatin and surfactant concentration, pH, and temperature. The evolution of the interfacial layers' properties (with increasing surfactant concentration) is discussed in connection with the properties and content of gelatin-surfactant complexes appearing in the aqueous phase. Such an approach allows us to explain the main peculiarities of layers' behavior including their stabilizing activity in relation to bilateral foam and emulsion films. © 2014 Elsevier B.V.

Based on recent experimental and theoretical model results, the role of earthquakes and processes of their preparation as electricity sources in the global electric circuit (GEC) is discussed. In addition to the traditional elements of the GEC, such as thunderstorm currents, ionosphere currents, fair weather currents, and telluric currents, hypothetical seismogenic currents flowing between the faults and the ionosphere are considered. The ionization sources for these currents are presumably the radiation of radioactive gases and the ionization by the electric field of so-called "positive holes" created by the compression of tectonic plates, whereas transportation of electric charges between the Earth and the ionosphere occurs under the action of electric fields and turbulent diffusion (for heavy charged species). Seismogenic currents deliver electric charges into the ionosphere, which give rise to electric fields in it and in the magnetically conjugated region. The drift of magnetized plasma in the ionosphere F2-region and plasmasphere plasma under the action of these fields causes disturbances in the electron density and total electron content (TEC) of the ionosphere, which are observed by GPS satellites before strong earthquakes. The typical features of these disturbances (magnitudes, dimensions, stability, nighttime predominance of the relative TEC disturbances, geomagnetic conjugacy) are well reproduced in theoretical model calculations based on the solution of the equation for the electric ionosphere potential with specified seismogenic electric current at the lower boundary of the ionosphere if this current is strong enough (comparable with thunderstorm currents). The feasibility of such seismogenic currents is discussed. It is argued that the TEC disturbances observed before strong earthquakes cannot be explained by neutral atmosphere disturbances. These TEC disturbances can be treated as ionospheric earthquake precursors created by seismogenic GEC disturbances. © 2013 Pleiades Publishing, Ltd.

The paper presents a review of studies on ionosphere quasi-static electric fields’ variations over seismically active regions. It also highlights the urgency of such review nowadays. The principle features of the considered disturbances are reported according to the INTERCOSMOS-BULGARIA-1300 and DEMETER satellites observations. The electrostatic disturbances take place in all (Ex, Ey, Ez) components of the ionosphere electric field vector, happen over the near-epicenter as well as magnetically conjugated regions and are observed from a few minutes to a few tens of hours before and after a seismic event. They are 1–26 mV/m in amplitude and 1°–20° in space. Paper also reports nighttime domination of the considered disturbances and their amplitudes dependencies on the earthquake magnitude as well as hypocenter depth. © 2015, Pleiades Publishing, Ltd.

Russia occupies a leading position in terms of crude oil production and provides 12% of the world oil trade. Russian exports of oil products the focus is European market. The world experience of the oil-producing complex demonstrates the need for the active involvement of the State in creating the conditions for its effective operations. One of the activities of the State addressing organizational and legal problems in the oil-producing complex is import substitution.

The coupling of the upper and lower atmosphere and the problem of developing a unified numerical model of the Earth's gaseous envelope is considered. The existing models of the upper and lower atmosphere are analyzed and specific models for use as parts of a future metamodels of Earth's atmosphere are selected. A general algorithm for combining these models is proposed. © 2013 Pleiades Publishing, Ltd.

The possibility of remote sensing ionosphere irregularities induced by auroral activity and affecting the Global Positioning System (GPS) signal is under consideration. The study reveals the dependence of GPS positioning temporal deviations on the auroral oval position and aurora disturbances throughout the polar region. The GPS data sets include the Antarctic and the Arctic GPS network receiver data, as well as the Kola Peninsula GPS original measurements. Auroral activity data include the satellite images of the auroral oval and the low light ground-based camera network data from the Barents Region. The aurora-induced ionosphere disturbances are supposed to be one of the main sources of GPS deviations in the Arctic and the Antarctic. A new method to study the impact of auroral disturbances on GPS positioning has been developed. The main idea of the method is to block the GPS receiver field of view in order to model the situation, with the GPS receiver inside the oval. Comparison of the GPS temporal deviations and the auroral intensity spatial and temporal variations show a good correlation in case studies. © 2011 Taylor & Francis.
