With the rapid development of the Internet, web applications are becoming more and more popular. Many people, groups, organizations, or governments use web applications as a means to share information or support business tasks. With the growing number of threats and attacks on web applications, organizations need a more effective concept of web application security. The article is devoted to the security of web applications and methods of ensuring security on a three-level data protection architecture. A three-level architecture is an architectural model of a software package that assumes that it has three components: a client, an application server, and a database server. Web application security is about protecting the privacy, integrity, and availability of an organization's web resources, as well as its reputation. It also includes policies, procedures, laws, people, and practices. Security, like other components of a web application, is best managed if it is planned at the initial stage of application development. The article also describes the methods of ensuring security. These methods will help security professionals develop security policies, conduct risk assessments, and eliminate potential risks in a cost-effective way.

Tien-Shan seismogen (TSS) is the modern mobile macro-fissure structural heterogeneity of lithosphere within which geodynamical processes occur accompanying intensive tectonic movements in earth’s crust and seismic phenomena [10]. The TSS is distinguished as a whole structural formation in the area of the joint structure of the Urals and Western Siberia with the structures of Central Asia by means of a complex of interpretation and analysis of a whole range of materials: geological, geophysical, etc. [1]. In order to study the current geodynamics of the structural irregularities of the Earth’s crust in the territory of North Tien Shan, which is the most seismically active in Central Asia, comprehensive geophysical studies are being conducted. Monitoring consists of three permanent observation points with a 24-hour programme. Those points are situated on seismic active part of Northern Tien-Shan. Kurty point is located in flat part of monitoring area (area with weak seismicity of the earth’s crust) and other points, Turgen and Medeo are located in seismic active part of Tien-Shan. Strainmeters are oriented in the North-South and East-West directions. Based on the experimental data obtained at Kurty, Medeo and Turgen points the bank of data was created. It contains hourly, daily, monthly and annual average values of deformations calculated by directions C-Y and B-3, as well as their modules. In this paper, the link between the deformation of rocks and atmospheric processes (the link between rock deformation and concentration density of electrons in ionospheric layers) are researched. According to trends, electron concentration in E layer increases but in higher layers decreases. Rock deformation in Medeo and Turgen area changes synchronously with the dynamics of the electron concentration in E layer and in Kurty area is antiphase. As a result, it is possible to trace the dependencies and links between the deformation of rocks and the geophysical and fluid processes of the Earth's crust, which, after analyzing and interpreting the data obtained experimentally, can be traced.

The solutions of a task of protection of water objects at development of mineral resources of Earth directed to prevention of breaks of water from superficial and underground sources and providing ecological balance of the earth's surface around conducting mining operations are presented.

To select an optimal and environmentally friendly technology for oil and gas development, it is necessary to estimate in advance the likely disfigurement processes of the surface terrain. To this end, it is recommended to develop predictive geodynamic models prior to start of field development, taking into consideration the geological characteristics and tectonic activity of the area under investigation, as well as the specific features of the reservoir. Research methods. In this paper, two models of subsidence of the ground surface in a hydrocarbon field are considered: a parametric spatial model developed at Delft University of Technology and a model based on the Knoté influence function developed at the Canadian Center for Geodetic Engineering. The first method is more suitable for describing a smooth and gradual subsidence in deep gas reservoirs and allows you to assess the spatial-temporal pattern of movement of the ground surface. In the second method, geodynamic processes are modeled based on the functional relationship between reservoir compaction and subsidence of the day surface, taking into account the location of the oil reservoir, physical and mechanical properties of rocks, changes in reservoir pressure and the results of surface disfigurement monitoring and is recommended for oil fields. Research results. A comparative analysis of these methods is carried out on the example of the Tengiz oil and gas field in Western Kazakhstan. An evaluation of the developed model accuracy is carried out by comparing the calculated values ​​of soil subsidence with the data of radar interferometry, and estimates obtained by other researchers. Recommendations are given on the application of the considered methods in the generation of predictive models of oil and gas fields, the necessity of calculating the transfer coefficient of the reservoir compaction to the position of the day surface, taking into account the depth of the reservoir and the physical and mechanical properties of the rock massif, is indicated.

Sulfide ores play an extremely important role in the development of the mineral resource base of Russia, as a source of rare, non-ferrous, and precious metals. However, the development of sulfide ore deposits is associated with the risk of sulfide dust explosions, the development of oxidative processes that lead to spontaneous combustion of ores. The article substantiates the urgency of solving the problem of reducing the risks of sulfide dust explosions, taking into account changes in the mineral balance of gold-sulfide deposits. To improve the safety of the development of sulfide-containing deposits, the authors developed new methodological approaches to the assessment of the explosion hazard of sulfide dust, based on the integration of model, laboratory and field experiments with a comprehensive analysis of the results. The developed methodology for studying the main factors of dust and explosion safety is an integral part of the industrial safety system, as it provides the possibility of forecasting, evaluating, and promptly determining the state of potential sources of fire and explosion hazard in the development of pyrite deposits.

Molars of the southern elephant Archidiskodon meridionalis gromovi were found in alluvial deposits near Uralsk (West Kazakhstan region, Republic of Kazakhstan). In this work, were applied generally accepted paleontological methods of field and cameral research: standard methods of working with paleontological material for extraction of samples from the host rock; morphometrically morphological analysis of fossil remains in the species diagnosis. Have been studied a series of teeth of M3/m3 shifts of chronologically successive subspecies of Archidiskodon meridionalis from paleopleistocene (middle villafrancian) localities in Western Kazakhstan. Analysis of the characteristics of teeth (frequency of plates, length of one plate, number of plates, enamel thickness, hypsodont index, crown proportion index) showed that the studied indicators are close to those characteristic of Archidiskodon [Elaphas] meridionalis gromovi. For the studied tooth changes, the parameter of the length of one plate turned out to be very diagnostic. The limits of variation in the size of the crown of teeth in different subspecies largely coincide.

his paper presents a methodology that can be used to create immersive virtual reality applications for teaching, conceptual modeling in the field of virtual reality, and specifically virtual prototyping, in various fields of application. The main stages of virtual reality application development are analyzed: planning; visualization; programming; user interface; testing, as well as tasks for the virtual assembly of parts, solved using a set of software and hardware visualization tools. The use of virtual reality technologies in the educational process can improve academic performance and at the same time reduce the number of errors and costs. Virtual learning experiences should not be about learning, so these learning environments need to be designed with a constructivist approach to reap the full benefits of learning.
