Aquifers in carbonate karst rocks are characterized by a known extreme heterogeneity of hydrogeological parameters both in the plan and in the section. This paper presents the results of the study of the distribution of permeability and capacity of the Podolsko-Machkovsky limestone aquifer in the scale of the first meters. On the basis of theoretical developments, supported by many years of field experimental research, it is shown that the main elements of the aquifer structure are thin permeable zones formed as a result of the karstification on the contacts of limestone layers of different lithological composition (bedrocks). The zones do not have measurable thickness and are characterized by individual transmissivities and specific capacities varying at distances of about a meter. The zones are separated by relatively low-permeability layers of unkarsted limestone. The methods of flowmetry in the static and dynamic variants, resistivimetry with details in determining the flow rate are used to identify the thin permeable zones. Layer and zone contacts are performed using electrical logging. Changes in the horizon transmissivity and the specific capacity of the zones in the cluster of 7 wells on an area of about 40 m2 with distances between adjacent wells of 3 m, was determined by cross-wells pumping tests with the recording of pressures and temperatures. All applied methods are modified to solve the presented problems. Even in such an area the neighboring wells show the difference of the aquifer conductivity almost one and a half times. Specific capacities of one thin zone vary by an order of magnitude. The asymmetry of the determined parameters at changing the roles of the experimental and observation wells has been revealed. The results allow us to take a new look at the problem of accuracy of the initial information for hydrogeological modeling — the studied area corresponds to the usual block of the model.

The assessment of ecological-geomorphological conditions of Verkhneandomsky (on the Upper Andoma river), “Atleka” and Andomskaya Gora (Andoma Mountain) protected areas was performed by Moscow State University and Moscow State University of Geodesy and Cartography researchers during 2002–2017. The aim of the study was to evaluate conditions for the development of exogenous relief-forming processes under the influence of natural factors using geoinformation systems (GIS). Topographic maps (scale 1:100 000) were vectorized and transformed to the uniform coordinate reference system (Gauss-Krueger projection, Pulkovo-42 datum). The GIS allows carrying out the ecological-geomorphological analysis of exogenous relief-forming processes of specially protected natural areas (PAs), relying on the grouped materials in the database, adding the parameters of the “erosion layer” and conducting their subsequent processing. Spatial analysis in GIS environment made it possible to identify similarities in karst processes and the difference in their intensity, expressed in the thickness and spatial distribution of the “erosion stratum” of the landscape reserves of the Verkhneandomsky and “Atleka”, which is defined by the relief of the karst-glacial-lake basin and the “karst” plateau, respectively. On the Andomskaya Gora natural monument, the suffusion-karst process and ravine dominate, which is caused by lithology (sand and sandstones) of rocks and significant relative height of the coastal ledge. Topographic, geological, geomorphological, and thematic information, as well as the boundaries and unique characteristics of the protected areas, allowed us to compile a series of derived maps reflecting the purpose of the research.

The article presents the outcomes of studying the transformation of audiovisual content in a new technological environment, which is one of the stages of the research project conducted by the Department of Television and Radio Broadcasting of the Journalism Department of Lomonosov Moscow State University. This stage held in July 2019 aims to identify the technological features of the work of the cultural and educational TV channel portals – “Russia K” (domestic channel) and ARTE (French-German channel). Both “Russia K” and ARTE are important media players that have been setting trends in their field for more than 10 years. The reason for comparing these channels was their thematic focus and a certain similarity of projects. The TV channel “Russia K” is the only non-for-profit channel dedicated to the cultural and educational topics in R SMAI, and ARTE TV channel is one of the most popular media specialized in this subject in Europe. During this stage the total amount of analyzed materials is 251 (145 publications on the “Russia K” and 106 on ARTE websites). The analysis of materials published on the Internet is based on following criteria: the number of materials, the nature of the content (broadcast / special), thematic and genre.The analysis of the amount of materials enables tracing the frequency of publication of new articles; data on the nature of the content helps to conclude which materials on the sites are more – on-air or special. Defining thematic and genre originality provides a complete picture of the content being posted.The author concludes that nowadays the Internet versions of the channels have their own faces but are inseparably bound with their television counterparts. The website of the TV channel “Russia K” is a vibrant media with recognizable style and creative presentation. However, in order to strengthen its position, the editors of the site should increase the number of copyright off-air materials and use new interactive genres (tests, quizzes, etc.).The site of the ARTE channel fits into the modern digital space while maintaining the classic presentation. Since most ARTE channel programs are timeless, they correlate very well with the consumer nature of the Internet and the need for educational content. Documentary films – the most common form of ARTE channel programs is in great demand by the audience in the digital environment that wants to quickly learn something important in a simple, vivid and understandable form.The difference between the on-air and non-air versions is largely exaggerated, because sites and channels do not compete with each other but are adjacent and complement each other. Websites enable access to the channel’s content anytime, anywhere, by selecting the desired program. Sites act not only as electronic repositories but also as individual units in the media world providing unique information.

During the AeroRadCity-2018 spring aerosol experiment at the Moscow State University Meteorological Observatory the aerosol properties of the atmosphere and radiative aerosol effects were analyzed using a wide complex of measurements and model COSMO-ART simulations over Moscow domain. The program of measurements consisted of columnar aerosol AERONET retrievals, surface PM10, black carbon (BC) and aerosol gas precursors mass concentrations, as well as radiative measurements under various meteorological conditions. We obtained a positive statistically significant dependence of total and fine aerosol optical depth (AOD) mode (R2 ~0.4) with PM concentrations. This dependence has revealed a pronounced bifurcation point around PM10=0.04 mgm-3. The modelled BC concentration is in agreement with the observations and has a pronounced correlation with PM, but not with the AODs. The analysis of radiative effects of aerosol has revealed up to 30% loss for UV irradiance and 15% - for shortwave irradiance at high AOD in Moscow. Much intensive radiation attenuation is observed in the afternoon when remote pollution sources may affect solar fluxes at elevated boundary layer conditions. Negative (cooling) radiative forcing effect at the top of the atmosphere from -18 Wm-2 to -4 Wm-2 has been evaluated. Mean difference in visible AOD between urban and background conditions in Moscow and Zvenigorod was about 0.01 according to measurements and model simulations, while in some days the difference may increase up to 0.05. The generation of urban aerosol was shown to be more favorable in conditions with low intensity of pollutant dispersion, when mean deltaAOD550 was doubled from 0.01 to 0.02.
