  • Information maintenance of ecological safety for geographically distributed systems of hazardous substances storage

    Paper deals with the analysis and synthesis of geographically distributed systems for storage of hazardous substances from the environmental safety position. Particular attention is paid to the information layer to ensure environmental safety (ES) of these systems, which operates on the results of the processing of regulatory documents, environmental monitoring data, analytical reports, etc. Its operation is based on a system of specialized automated workplaces (AWP), each of which generates a plurality of projections and calculations in order to provide ES, using information on three levels of detail: the physical, technological and logical. The structures of mathematical, informationtion, software and hardware provision of AWP are discussed. It is shown that the proposed AWP structure can be used in the design of the various systems for storage of hazardous substances and is aimed to provide ES in their operation.

  • Security: destabilization and modelling processes of peace-making of society in gender research field

    This article is devoted to the problems of destabilization, conflict and problem areas in contemporary gender and family relations, mostly in the system of social roles realization. Selected problem areas promote not only destructive forms of relationships within the family unit and cause individual deep sense of dissatisfaction with life, but destabilize society on the whole, destroying peace and tranquillity both locally and globally. It is known that some contemporary types of gender and marital-family problems are very destructive to the existence of the whole social system. Such, in particular, can be called the imbalance of roles and inadequacy of prestige of the spouse/partner. Due to the urgency of the identified problems there increases the need for modeling the processes of peacemaking in the society, where the main actors can certainly become women. Female gender sub-group played a prominent role in peacemaking, in particular, during WW II , performing a variety of social roles.

    Keywords: peacemaking, security, family, gender, gender studies, world war II, "war bride"

  • Theoretical study of the local atomic and electronic structure of dimetacyano azobenzene molecules on Bi (111) substrate

    The present work is devoted to the local atomic and electronic structure of dimetacyano (DMC) molecules deposited on a Bi (111) substrate before and after irradiation by X-rays and UV light using density functional theory (DFT) and a theoretical analysis of the X-ray absorption near edge structure (XANES) spectroscopy. As a result of the calculations the low-energy structure for DMC azobenzene molecules on a Bi (111) substrate was obtained.

  • Assessment of the strength of reinforced concrete torsion

    A new approach to solving the problem of evaluation of strength of concrete in torsion. The basic idea of this theory is that the torsion causes the bending element in a plane 45 ° angle. Solved the problem of assessing the strength of rod reinforced concrete elements in torsion. Development of methods of calculation of durability of reinforced concrete elements in torsion has allowed to pass to the decision of problems of strength under twist with torsion.

  • Dynamic calculation and analysis of the hemispherical shell coating of the project "Winter Garden" Technopark Rostov State University of Civil Engineering (RSUCE)

    The article presents the dynamic calculation of hemispherical shells cover the carcass of the building "Winter Garden" Technopark RSSU. Finite element model of the object and the calculation is made in the software package Lira-cad. Flexural-torsional oscillations was produced on the basis of modal analysis. The construction scheme is changed by increasing the hardness of the coating. The scheme receive a new kind of a framework element. Using the findings of the calculations the conclusions were drawn and given recommendations about changing the constructive scheme of the unique building.

  • Regularities of zinc transformation process in ordinary chernozem in the presence of different anions

    The influence of attendant anions on the transformation of zinc compounds in the soil was studied in a model experiment. The differences in the number of mobile forms of recoverable zinc in the soil, depending on its dose and form of addition were defined. Influence of associated anions on the content of metals mobile forms in the soil decreases in the order: PO42¯≈ Cl¯ > NO3¯ > SO42¯> СН3СОО¯> О¯. Transformation of zinc compounds during 2-year period after the receipt of the metal in the soil has been studied.  There is no soil stabilization in ratio form for two years studying, indicating the low speeds transformation of metal compounds with soil components. Transformation of Zn in soil depends on the attendant anion, metal concentration in soil and time interaction with the solid phase of soils. The transformation process of metal adsorbed the soil goes toward to decrease of Zn mobility.
