The legal status of water bodies implies special measures aimed at preserving and preventing negative processes within the boundaries of a water body. A zone with a special mode of use is the territory, within the boundaries of which the mode of using the object for the purpose of protection and (or) to protect the environment is established. In modern geodesy, special satellites are used that are part of the global positioning system. The object is tied to the existing geodetic network, the identification marks are laid in a minimal amount, then aerial photography is performed and the photoplans are “stitched”. The emergence of electronic and unmanned measuring instruments during a complex of geodetic works greatly facilitated the work of geodetic engineers, allowing them to increase the productivity and accuracy of work performed when using such instruments.

The research of influence of periodical signal discontinuity on spectrum form is considered in the article. The numerical modeling of the system of discontinuous signals is performed. The spectrum of the system built from time discreet sampling is analyzed. The plots of the sample correlation coefficient between spectrums of continuous and discontinues signals are shown in the article. The research is needed for the development of digital measuring system for quartz plates frequency detecting.

Keywords: amplitude signal spectrum, discontinuous signal, quartz plates

A model system was designed and test  trials of physical and mechanical characteristics of small – crystalline and granular flotation potassium chloride are studied. This model system allows to design storage and transportation  of fertilizers in bulk in railway wagons and it has the same static and vibrational load as real system. The effect of temperature and relative humidity of the air on hygroscopy of small – crystalline and granular КСl were studied. Furthermore the influence of static load, and time length  of compression process of fertilizing layer and parameters of static and vibrational load on composition of КСl granules were investigated. It was experimentally proved that the humidity increase (0,5 %) of granular КСl and the  increase of static load and time length  of compression process of product during transportation in bulk lead to increase of compaction degree and caking ability of product. Research of the influence of high static load (10-30 kg/sm2) and time length of compression process of fertilizing layer on caking ability and degree of compaction show that small – grained KCl has smaller degree of compaction and considerably higher value of caking ability in comparison with granular KCl.

The kinetics of the electrodeposition of zinc to the steel base of the sulfate electrolyte supplements with synthetic surfactants was studied. Found that at potentials more positive than the equilibrium value the process of pre phase zinc deposition. Additives synthesized organic compounds adsorbed to the surface of the electrode at its cathodic polarization, increasing of overvoltage process. The adsorption is in the range of 0,5•10-7 to 2,6•10-5 mol/сm2.

Digital compact proton magnetometer was created for measure the geomagnetic fields, including the fields of high heterogeneity. We described design of the instrument and its principles of operation. This device is using implemented digital filtering techniques and Prony method to determine the frequency of the desired signal. The experiments were made in the fields of high heterogeneity and demonstrated the possibility of precise measurements in the fields with a gradient of up to 8 mT / m. The device can be used as a metal detector, as well as for magnetic prospecting, geological studies, etc.

  The article analyses the problem of applying the scientific method of modeling to the investigation of geopolitical processes taking place at the world regional/sub regional “sites”. Preceding from three possible approaches to studying geopolitical dynamics under glocalisation, that is description, formalization and quantification, the author analyses three structural levels of geopolitical modeling. With this purpose in view he analyses the peculiarities and such constituents of its modification as ordinary, conceptual-graphical (cognitive) and mathematical modeling. Special attention is given to conceptual-graphical modeling and its specific language. Admitting the possibilities of using precise mathematical methods and procedures in geopolitics, the author takes into consideration their scantiness. In this respect the validity of mathematical methods and procedures must be provided with quality expert evaluation. The author's message is that the use of heuristic options of modeling in regional geopolitics may serve as the pledge to growing science capacity of this field of knowledge.
