Abstract
Water-borne diseases like diarrheagenic Escherichia coli (DEC)-induced gastroenteritis are major public health problems in developing countries. In this study, the microbiological quality of water from mines and shallow wells was analyzed for human consumption. Genotypic and phenotypic characterization of DEC strains was performed. A total of 210 water samples was analyzed, of which 153 (72.9%) contained total coliforms and 96 (45.7%) E. coli. Of the E. coli isolates, 27 (28.1%) contained DEC genes. The DEC isolates included 48.1% Shiga toxin-producing E. coli (STEC), 29.6% enteroaggregative E. coli (EAEC), 14.9% enteropathogenic E. coli (EPEC), 3.7% enterotoxigenic E. coli (ETEC), and 3.7% enteroinvasive E. coli (EIEC). All the STECs had cytotoxic effects on Vero cells and 14.8% of the DEC isolates were resistant to at least one of the antibiotics tested. All DEC formed biofilms and 92.6% adhered to HEp-2 cells with a prevalence of aggregative adhesion (74%). We identified 25 different serotypes. One EPEC isolate was serotype O44037:H7, reported for the first time in Brazil. Phylogenetically, 63% of the strains belonged to group B1. The analyzed waters were potential reservoirs for DEC and could act as a source for infection of humans. Preventive measures are needed to avoid such contamination.

Published: May 2019

The article determines main factors of the need for modern conditions of temporary setting aside trains from the traffic, which require consideration of this operation not as an emergency forced measure, the need for which arises because of operational personnel errors, but as one of the elements of the transportation process technology that require it rational organization. These factors are: formation of large unloading areas in seaports taking into account recurring difficulties in its work, technical equipment failures and traffic safety violations, daily irregularity of train operation, etc. Principles of building a rational strategy for temporary setting aside trains from traffic are considered. It makes provision for: using the capabilities of the operational area infrastructure as a whole for set aside trains, impermissibility of reducing the carrying capacity of previous sections of the difficult section below its carrying capacity as a result of set aside trains, selecting stations for set aside trains based on feasibility studies.Use of a cost-effective strategy for the temporary setting trains from traffic in the event of operational difficulties will minimize the expenses of the JSC “Russian Railways” related to the need to carry out this element of the transportation process technology.

Published: May 2019

Objectives.Analysis of the existing methodology for the formation of requirements for information protection systems (GIS) from unauthorized access (NSD) to automated systems (AS) revealed a number of significant flaws, the main of which is the following: despite the fact that the considered method undoubtedly has theoretical significance, the same time, it can not claim practical value. This is due to the fact that in this methodology, the studies were carried out not on a specific standard (widely used certified according to the regulations of the Federal Service for Technical and Export Control of Russia) GIS, and the data on threats of unauthorized access given in it do not correspond to reality (morally obsolete), but therefore require a significant upgrade. Accepting the existing methodology as a baseline, the purpose of the article is to develop a private method of forming requirements for GIS from unauthorized access to the AU, which has practical value and allows you to formulate quantitative requirements for a wide class of certified GIS.Method.When writing the article, the methods of system analysis, evolutionary modeling, probability theory and mathematical statistics, mathematical apparatus for modeling dynamic discrete networks (E-networks), and theory of algorithms were used. The methodological basis is a systematic approach.Result.A private methodology has been developed that determines the parameters of the symbolic genetic algorithm (GA) for creating a software package for analysis, evolutionary modeling, and forming quantitative requirements for GIS from un-authorized access to speakers using the Matlab 13 application software to implement GA in the Optimization toolbox programming environment.Conclusion.The proposed private method of forming requirements for GIS from unauthorized access in the AU using GA has a theoretical significance, practical value and allows you to formulate quantitative requirements for a wide class of AS certified in a certain class of security in accordance with the requirements of current regulatory documentation.

Published: May 2019

Objectives.The aim of the study is to develop a method of operating geothermal energy systems in the mode without scaling when disposing of flammable gases with geothermal water in wells with a low gas factor.Method.The studies were conducted on the basis of analyzing the content of associated flammable gases in the underground thermal mineral waters of the North Caucasus and Ciscaucasian deposits and assessing the possibility of their utilization and use for heating and hot water supply. In this case, the laws of dissolution and desorption of methane and carbon dioxide from groundwater solutions with the content of scale-forming components, in particular, calcium carbonate, are used.Result.On the basis of the conducted research, it was found that the operation of g eothermal systems in the power industry should be carried out after preliminary withdrawal of the maximum possible amount of associated flammable gases from a water solution, while maintaining the content of carbon dioxide in water at a level above the equilibrium value. The scheme of the effective operation of thermal distribution stations with the prevention of carbonate deposits in them is given by using the products of associated gas combustion in the waste water when it is pumped back into the aquifer.Conclusion.As a result of the research conducted, a method of operating geothermal energy systems in a non-salt-scale mode has been developed for utilization of combustible gases associated with geothermal water. It has been established that in order to accelerate the dissolution of carbon dioxide in water to stabilize it before entering heat-exchange equipment, it is advisable to increase the partial pressure of carbon dioxide to values exceeding by an order of magnitude the equilibrium at a given temperature. At the same time, before pumping waste water back into the aquifer, excess carbon dioxide is removed from the water.

Abstract
Modern scanners can perform terrestrial topographic survey with resolution of 1 cm and accuracy of 2 mm in just a few minute‘s time, from the distance of up to 100 meters. However, for surface topographical surveying of large territories or complex industrial objects, it is necessary to conduct geodetic traverses and perform their binding to the points of the geodesic basis. One method of coordinate transferring during surveying is by using the method of inverse linear-angular intersection, which involves the measuring of the respective sides S
1, S
2 and the β angle between them. This method is more precise than the classical one, which usually contains centring and reduction errors. The linear-angular intersection method can also be used for many applications in engineering geodesy, for laying geodetic traverses, and for binding to the wall based points of ground-surveying.

Abstract: Improving the efficiency of data processing of the Advanced Multi-electrode Electrical Sounding method is a practical work and necessary. Previously, we have used the Advanced Multi-electrode Electrical Sounding method to locate saturation line in the earth dam with the positive results. However, one of the data processing steps only stopped at Trendline method, hence the difference to the results measured by the Pizomet systems is good but a lot to be desired. In this paper, we present several new results determining the saturation line of earth dam in Dong Mo, Ha Noi by the Advanced Multi-electrode Electrical Sounding method using the interpolation method and the second derivative during data processing. The results are more accurate than the previous results, with the biggest error of 5.1% compared to the results determined by Pizomet system.
