    One of the priorities of engineering geology in the development of underground mineral deposits is the dynamics of changes in geotechnical conditions as a result of anthropogenic factors and the degree of impact on existing buildings and structures. The most significant anthropogenic impact is associated with the extraction of minerals and host rocks. As a result of the development of the underground space, deformations of the earth's surface occur. It results in the subsidence features, changes in curvature, slope, compression and extension of rocks as a result of horizontal and vertical deformations. In turn, it leads to a change in the hydrological and hydrogeological regime, activation of exogenous processes, etc. This article presents the results of the creation of a GIS system to solve the forecast problems of changing engineering and geological conditions as a result of anthropogenic impact. The use of GIS technologies allows specialists to provide reliable and relevant information for assessing geotechnical risks in mining areas and making proper management decisions. The result of prognostic modeling should be a set of maps (cartographic layers) in the zone of influence of mining operations, containing the following information: forecast of the degree of anthropogenic impact, forecast of changes in geotechnical, hydrogeological, engineering and geological conditions, identification of objects on the earth’s surface that are in danger. Based on these predictive calculations, it is necessary to develop measures to reduce the negative impact. Such informational models of the territory should be supported at all stages of the life cycle of the field that will allow receiving high-quality information about the engineering and geological conditions of the developed territory at any time.Одной ΠΈΠ· ΠΏΡ€ΠΈΠΎΡ€ΠΈΡ‚Π΅Ρ‚Π½Ρ‹Ρ… Π·Π°Π΄Π°Ρ‡ ΠΈΠ½ΠΆΠ΅Π½Π΅Ρ€Π½ΠΎΠΉ Π³Π΅ΠΎΠ»ΠΎΠ³ΠΈΠΈ ΠΏΡ€ΠΈ Ρ€Π°Π·Ρ€Π°Π±ΠΎΡ‚ΠΊΠ΅ мСстороТдСний ΠΏΠΎΠ»Π΅Π·Π½Ρ‹Ρ… ископаСмых ΠΏΠΎΠ΄Π·Π΅ΠΌΠ½Ρ‹ΠΌ способом являСтся ΠΈΠ·ΡƒΡ‡Π΅Π½ΠΈΠ΅ Π΄ΠΈΠ½Π°ΠΌΠΈΠΊΠΈ измСнСния ΠΈΠ½ΠΆΠ΅Π½Π΅Ρ€Π½ΠΎ-гСологичСских условий Π² Ρ€Π΅Π·ΡƒΠ»ΡŒΡ‚Π°Ρ‚Π΅ влияния Ρ‚Π΅Ρ…Π½ΠΎΠ³Π΅Π½Π½ΠΎΠ³ΠΎ Ρ„Π°ΠΊΡ‚ΠΎΡ€Π° ΠΈ стСпСни Π΅Π³ΠΎ воздСйствия Π½Π° ΡΡƒΡ‰Π΅ΡΡ‚Π²ΡƒΡŽΡ‰ΠΈΠ΅ здания ΠΈ сооруТСния.

    Polymers pushing Polymers: Polymer Mixtures in Thermodynamic Equilibrium with a Pore

    Get PDF
    We investigate polymer partitioning from polymer mixtures into nanometer size cavities by formulating an equation of state for a binary polymer mixture assuming that only one (smaller) of the two polymer components can penetrate the cavity. Deriving the partitioning equilibrium equations and solving them numerically allows us to introduce the concept of "polymers-pushing-polymers" for the action of non-penetrating polymers on the partitioning of the penetrating polymers. Polymer partitioning into a pore even within a very simple model of a binary polymer mixture is shown to depend in a complicated way on the composition of the polymer mixture and/or the pore-penetration penalty. This can lead to enhanced as well as diminished partitioning, due to two separate energy scales that we analyse in detail.Comment: 10 pages, 6 figure

    NASSAM: a server to search for and annotate tertiary interactions and motifs in three-dimensional structures of complex RNA molecules

    Get PDF
    Similarities in the 3D patterns of RNA base interactions or arrangements can provide insights into their functions and roles in stabilization of the RNA 3D structure. Nucleic Acids Search for Substructures and Motifs (NASSAM) is a graph theoretical program that can search for 3D patterns of base arrangements by representing the bases as pseudo-atoms. The geometric relationship of the pseudo-atoms to each other as a pattern can be represented as a labeled graph where the pseudo-atoms are the graph's nodes while the edges are the inter-pseudo-atomic distances. The input files for NASSAM are PDB formatted 3D coordinates. This web server can be used to identify matches of base arrangement patterns in a query structure to annotated patterns that have been reported in the literature or that have possible functional and structural stabilization implications. The NASSAM program is freely accessible without any login requirement at http://mfrlab.org/grafss/nassam/
