To date, the most effective is thermal hydrogenation catalysis, which is an advanced part of the science of processing rubber and polymer waste. This, on the one hand, will allow these processes to be carried out with the participation of cheap and effective catalysts and in soft conditions in order to find alternative sources of hydrocarbons for oil and natural gases. The increasing use of polymer materials in all industries and everyday life, as well as the reduction of their service life has led to one of the important problems facing the world civilization, the problem of environmental pollution by polymer waste. Such waste is not split in natural conditions and ignites when Gorenje with the release of harmful toxic substances. The solution to this problem lies in the development of new technologies for processing industrial waste, as well as the search for catalysts that solve the problem of fuel shortage. In the process of thermocatalytic hydrogenation during processing of polymer waste, hydrocarbon fractions similar to motor fuels will be obtained. In general, this will allow us to process secondary raw materials, add additional fuel materials to the market, and have a positive impact on the environment. New catalysts based on natural zeolite from the Taijuzgen deposit modified with W (VI) salt were studied in order to jointly study the processes of thermocatalytic hydrogenation of plastic waste and optimize the process.

Unavailability of domestic production of potash fertilizers in Kazakhstan causes high demand for potash salts, which agricultural producers currently have to import from neighbouring countries. At the same time, Kazakhstan has an unique raw material base of potash ores concentrated in the West Kazakhstan and Aktobe regions, whose reserves are considered as one of the largest in the world. The explored Chelkar carnallite ore deposit has not yet been adequately studied, and industrial development has not yet begun. We conducted a series of studies to determine chemical and mineralogical composition of the potash ore and to study rational processing methods. It was established that the ore has complex mineralogical composition, including both potassium components - carnallite and glaserite, and halite and gypsum. Due to non-uniformity of raw material composition, the method of ore processing by washing it from sodium chloride, which is an impurity mineral in this system, has been studied. The method of incomplete dissolution was chosen for the potassium enrichment of this multicomponent system. Investigations of this process have allowed to determine the process optimal mode for processing carnallite ore with water: temperature 20°С, washing time 30 minutes, water flow rate - 1 mass part per 1 mass part of raw materials. The established washing conditions make it possible to maximally remove sodium salts from the system and enrich Chelkar deposit potassium ore on potassium components, which can be processed using the mineral-salt method at the next stage. The optimal enrichment mode should also be worked out using washing water, or mother liquor, to wash the original ore in order to reach maximum washing from sodium with a solution saturated with potassium.

For many decades, the oil fields of the Mangistau region have developed a predominant raw material system of nature management with extremely high technogenic loads on the environment. Such loads contribute to the destabilization of the biosphere leading to the loss of its ability to maintain the quality of the environment necessary for the society life.
A comprehensive analysis of the environment includes an assessment of its ecological state and the impact of natural and anthropogenic influences on it. The nature of these impacts on the environment in close proximity to industrial enterprises is very specific, not always sufficiently studied and requires solving a whole range of scientific and practical problems.
In recent years, in Kazakhstan the priorities in environmental policy based on MPCs and other rules and regulations the impact on the environment, are being reviewed. The reason: the low efficiency of the normative approach due to the possibility of a subjective approach to the “norm” and manipulation of this concept. In this regard, the concept of environmental risk is gradually being laid in the basis of the state environmental policy in the conditions of progressive pollution. In the article the data on the ecological state of the Kalamkas deposit have been given. The composition of the dissolved gas is dominated by methane, with an average content of 85.5 – 93.4%. The ethane content on average does not exceed 7.1%, and the high potential composition of propane does not exceed 184 g/m3. The average gas density does not exceed 0.896 g/l.

Вased on copper(II) chloride and polyethylene glycol a polymer-metal complex was synthesized, and its composition was established by potentiometric and conductometric methods. The values of the Bierrum’s formation functions were calculated. Titration curves were constructed. The optimal molar ratios of the reacting components were found. The data obtained indicate the formation of polymer complexes of copper, in which two complex mono units of polyethylene glycol account for one metal complexing ion. The coordination saturation of the metal-complexing agent in this complex is due to solvent molecules or the anion of metal salts. The thermodynamic characteristics of the complexation process were calculated: ΔrG0, ΔrН⁰, ΔrS⁰. Negative values of the Gibbs’ energy change indicate the potential possibility for the process under study in the direction of the formation of the polymer-metal complex. A positive value of the change in enthalpy (ΔrН⁰) in the temperature range 298-318K indicates the endothermic nature of the formation of the polycomplex in the indicated range. Changes in entropy values are associated with the destruction of the solvate shells of the PEG’s ligand groups and copper ions, the displacement of solvent molecules and the formation of chelate structures. Using IR spectroscopy, it was confirmed that the oxygen atoms of the polymer ligand are involved in the formation of coordination bonds with the metal complexing ion.

Composition and physicochemical properties of humic acids (HA) extracted from brown coals of the Ekibastuz coal basin (the Republic of Kazakhstan) were studied by using the methods of IR spectroscopy, X-ray fluorescence analysis, and potentiometric titration.
In the analysis of multicomponent complex substances, which include HA, information may be limited due to the mutual influence of individual groups. However, the information obtained regarding the structural features of HA with a combination of various research methods can be very useful. Using IR spectroscopy, it was found that the studied humic acids contain aliphatic and aromatic alcohols, esters, carboxylic acids, as well as conjugated double bonds.
Electron (X-ray fluorescence ) spectroscopy showed the presence of polyenes in the studied humic acids, as well as aromatic fragments and their oxygen-containing derivatives, which is consistent with known data, according to which the main chain of humic acid molecules is built from fragments of diphenylcarboxylic acids.
By the methods of heterogeneous and homogeneous potentiometric titration, the content of carboxyl and hydroxyl groups in the structure of HA molecules was studied. It was shown that the results of potentiometric titration depend on the titration method (homogeneous and heterogeneous) and the concentration of humic acids in the system. It was established that the total content of acid groups (carboxyl and hydroxyl) depends on the concentration of humic acids and it is higher at low concentrations of HA.

Kazakhstan is one of the biggest country in the world, but approximately 70 % of our land covered by desert. In addition, more landscapes are becoming desert due to lack of water resources. Structuring of soil with hydrogel is one of the known method that currently used in water-lack countries in the world. Thus, investigation of hydrogel with high water absorbing ability is one of the important problem in the world.
In this work hydrogels of N,N-dimethyl acrylamide and 2-Acrylamido-2-methyl-1-propanesulfonic acid monomers were synthesized by radical polymerization in presence of N,N-methylene bis acrylamide as a cross-linking agent and ammonium persulfate initiator.
The parameters affecting on the conversion of co-polymerization such as initial concentration of monomers, temperature, initiator dose and contact time were investigated. The swelling degree of the hydrogels was determined by adding different amount of cross-linker and initiator. As a result, the optimal conversion parameters were determined, such as the initiator concentration (0.07%), the cross-linker concentration (0,74%), the optimal temperature (60℃), and the co-polymerization time. The experimental data were reasonably described systematically. The resulted hydrogel could be used in different purposes in agriculture and seed coating etc.

This work is based on processing the surface of aluminum foil with a purity of 99.999% in a high-frequency plasma discharge using the established parameters, forming an ordered membrane of nanoporous aluminum oxide using an electrochemical anodizing process on the surface of this treated aluminum foil, and determining how much the results obtained in the study depend on the parameters of the experiment. As the main parameter, the value of the power of the high-frequency discharge was used. The surface of pure aluminum foil in the same 50 micron thickness is treated with three different power values. In the course of the study, it was noted that surface roughness depends on different power values of 20 W, 50 W and 70 W. In accordance with the first part of the experiment, the surface of pure aluminum foil is treated with plasma in a high-frequency discharge, as a result of which changes were detected during the research. As a result of the study, it was found that the plasma treatment of the surface of aluminum foil formed tracks that were installed using a scanning electron microscope and determined their features. It was found that these changes depend on the amount of power of the high-frequency discharge during plasma processing. The surface of aluminum foil treated with plasma and nanoporous aluminum oxide membranes formed after electrochemical anodizing were studied using a scanning electron microscope, and it became known that the power value affects the location of tracks and how densely or remotely the porous structures formed after the electrochemical anodizing process are formed. In General, this work is based on processing the surface of aluminum foil using high-frequency plasma to produce an aluminum oxide membrane.

Warm dense matter is characterized by strongly bound ions and is a strongly bound quantum system. Strongly bound plasma is the subject of active theoretical and experimental studies, such as the study of astrophysical objects and plasma in inertial fusion plants at present. In such a strongly coupled plasma, collective effects (screening effects) occupy an important place. The effective interaction potentials of charged particles are used to take into account screening effects, i.e. take into account the effect of surrounding particles on interparticle scattering in the system. The effect of electron nuclei can be described by the effective electron-ion potential, strongly modified near the nucleus when approaching the Coulomb potential at large distances. In a partially ionized plasma, the interaction between free electrons and ions also depends on occupied bound states. In this regard, in this article, the screened potential of the interaction of ions is considered taking into account the influence of occupied ground states on the interaction of free electrons with ions in a partially ionized plasma. The simplest form for such a pseudopotential is the empty core potential. In this article, to eliminate the influence of strong oscillations in the Fourier space, we used the potential with a soft empty core. Graphs of this potential of ion-ion interaction at various plasma parameters are presented. The considered interaction potential of ions at large distances is shielded weaker than in the case of Yukawa shielding. With an increase in the coupling parameter over long distances, the screening becomes weaker due to an increase in the ion thermal wavelength.

The demand for emulsions in the field of chemistry, medicine and cosmetology is enhanced by the properties inherent in emulsions, that emulsions have two or more different phases, forming capsules that are isolated from the external environment. These capsules can contain substances with certain qualities and can be used for different purposes.
In this regard, the development of technology for producing an emulsion is an important area in industrial chemistry. The stability and functionality of emulsions are the most important indicators of emulsions, and the availability and safety of the substances used, the simplicity of the methods are important requirements for technologies to obtain an emulsions.
This article describes a review of foreign and domestic literature on modern technologies and the principles of multiple emulsions obtaining, on the types and effectiveness of stabilizers. Nowadays, to obtain emulsions, different types of emulsifiers are tested, the stabilizing properties of many compounds, from rare to accessible and simple compounds, is being studied, and technologies are being developed for obtaining from double to quaternary emulsions.

The article discusses the results of a study of pH – sensitivity of microparticles of calcium alginate (Ca – ALG) and Ca – ALG/GEL containing gelatine. It was found that when the pH of the medium of a 0.9% NaCl solution changes from 1.2 to 7.4swelling (Kswell) and the rate of release of richlocaine from these particles noticeably increase. Gelatin enhances this effect.

In this work, the protective property of the electrochemically synthesized poly (anilineo- anisindin) copolymer (PAOA) in a 3.5% NaCl solution at various exposure times was studied by impedance spectroscopy. Based on the Nyquist diagrams, the degree of protection, the degree of water absorption, and the thickness of the copolymer coating were calculated. It was found that the values of the protective properties do not obey a certain regularity due to poor adhesion of the coating synthesized from an oxalic acid solution. According to the calculation result after 120 minutes of immersion of the coating in an aggressive environment, the following values were obtained: Z = 78.95%, % = 33.80 and d = 11.00 nm

This paper presents the results of research on the topic “Development and implementation of technologies for obtaining semiconductor, photosensitive and fluorescent nanomaterials based on the processes of directed synthesis of metal sulfides from unitiolate coordination compounds”. This paper considers the growth of nanocrystals on a multicomponent silicate glass in which the semiconductor phase, with a concentration of approximately 1%, was dissolved during synthesis. During secondary heat treatment of glass samples, nucleation and growth of semiconductor nanocrystals occurs as a result of diffusive phase decomposition of a supersaturated solid solution.

Technical emulsions of Vaseline and water stabilized by anionic surfactant — sulfonol (SF), cationic surfactant — cetylpyridinium bromide (CPB) and their mixtures with polyacrylamide (PAA) were obtained. It was shown that surfactant compositions with a polymer have a lower stabilizing effect on emulsions, which is associated with a decrease in the surface activity of surfactant – PAA complexes compared to individual surfactants. The isotherms of surface tension of surfactants — CPB and SF and their compositions with PAA — were obtained. A correlation was found between the surface tension of surfactant-PAA compositions and the demulsifying effect of surfactant-PAA compositions on Vaseline emulsions. The use of PAA compositions with surfactants opens up new possibilities for the development of effective demulsifies.

To date, the disposal of waste from the production of soda ash using the ammonia method is an urgent problem in all countries producing soda according to the ammonia method. In this regard, a technology has been proposed for the integrated processing of lead fuming slags using distilled liquid as a chlorinating component, which allows solving the problem of the utilization of industrial wastes from the metallurgical and chemical industries simultaneously. The distilled liquid, which is a waste of soda production, is a solution of calcium and sodium chlorides contaminated with impurities of calcium carbonate and sulfate, slaked lime, sand and other substances that are mainly in the solid phase. The distiller liquid is 8.5m³ ton of soda, g / m³: СаСl₂ 118-125; NaCl 58,6-80 ; CaCO₃ 6-15; CaSO₄ 2-2,7; Mg(OH)₂ 3-10; CaO 2-4; Fe₂O₃ +Al₂O₃ 1-3; SiO₂. Thermodynamic modeling of systems characteristic of sintering firing established technological parameters and compositions of raw mixtures that provide the maximum degree of extraction of metal chlorides. For carrying out agglomeration-chloride sublimation roasting of slag, the process temperature should not exceed the melting point of the slag (12000С), that is, a maximum of 1100-11500С. The compositions of raw mixtures based on fuming slag, distilled liquid, bentonite clay and coal wastes were experimentally established, which ensure the recovery of lead-80.97%, zinc-78.09%, copper-76.52%. The physical and mechanical properties of the granules after roasting indicate high dynamic and static strength.

Radical co-polymerization of N, N-dimethyl-N,N-diallyammonium chloride (DMDAAC) with N,N-dimethyl acrylamide (DMAA) has been investigated by the dilatometer technique using ammonium persulfate ((NH4)2S2O8) as an initiator. The influences of the molar ratio of DMDAAC to DMAA, concentrations of monomers and initiator, temperature on polymerization rate have been analysed. From these analysis it was found that DMDAAC concentration in monomers composition conversely affects the polymerization rate. Based on the experimental results, the polymerization mechanisms were discussed in more detail.

In this article we have covered many approaches of implementing personalized training recommendation system based on collaborative filtering. These techniques are consist of memory based methods, where we apply our statistical methods to the entire dataset to make predictions. We have considered such algorithms as cosine similarity and Pearson correlation. For cosine similarity we consider users data as vector of some collaborations in N dimensional space, where N is number of items. Then we calculate similarity of any two users as cosine of an angle between their vectors. This technique end up with good results, but anyway there is a problem, because of the matrix sparsity (empty interactions). Considering them as 0, impacts results even if we remove mean from each existing collaboration. Therefore, we also considered Pearson correlation which operates better with empty spaces in our data matrix. Here we try to find positive or negative trends between users and get correlation coefficient to predict rating.
At the end of article we have compared all techniques based on such approaches as measuring RMSE and MAE

Text summarization is one of the major problems because it has a high range of usage in various fields, it is most important to have an improved mechanism for the fastest and most effective extraction of the information. The extraction of the summary from all that available source of text data by hand is very difficult. In order to show the ways for solving the text summarization, this paper presents a brief survey of various text summarization methods like MatchSum (Zhong et al., 2020), BertSumExt (Liu and Lapata 2019) and SemSim (Yoon et al., 2020) which has shown the leading results in extractive and abstractive text summarization. This paper reviews those models and shows their advantages and disadvantages, makes a guess how text summarization can be improved.

This article discusses the role of cereal waste from sown areas to obtain organic mineral biological fertilizers from straw of cereal crops in crop production. The introduction of straw increases the content of humus, improves the structure of the soil, reduces its tendency to erosion, and stimulates the process of nitrogen fixation. It is a food source for soil microorganisms, without which the availability of individual nutrients would be limited. Water and air regimes and soil absorption also improve. The method for the production of fertilizers from straw, proposed in the article, includes processing the feedstock by grinding it with simultaneous heat and pressure, further filtering the feedstock with water and carrying out the process in a nitric acid reactor, then the product is sent to an acid neutralizer. Thanks to the proposed method, we obtain a combined fertilizer containing, in addition to nitrogen in the ammonium form, i.e. the most valuable form in terms of nitrogen fertilizers, is also another component, potassium, which is important too.

Spam, viruses, spyware are the risks that they expose themselves to users, using the services of the Internet. Modern threats of the Internet is much more complicated than those that were before. They are more resistant to remedies. Threats of the 21st century possess such properties as dynamism and transformability. Often they are carried out using zero-day vulnerabilities - unresolved vulnerabilities or vulnerabilities for which a defense mechanism has not yet been developed. Such attacks often pass unnoticed by many protection tools, IPS, antivirus Software and firewalls. The market critically lacks not only the resources that can handle all incidents, but also the overall system, thanks to which it would be possible to respond to them in the early stages of cyberattacks - ideally before operation, as well as to accumulate distributed knowledge about threats, exchange received data, investigate causes of threats and respond immediately to them. For faster accumulation of information about possible threats, one should strive to share useful data from a wide range of sources. At the same time, it is important that this information is standardized, that is, the standards and protocols for the transmission and provision of data defined in advance. The capability to detect, analyze, and defend against such threats in near real-time conditions is not possible without the employment of threat intelligence. This paper reviews the main definitions, instruments in Threat Intelligence technology. Moreover, how this technology may help to reduce cyber security risk. Threat Intelligence can help to prevent many problems recurring in information systems.

The article presents the results of studies evaluating the strength of anchoring of flexible ties in the form of pins in thin outer layers of panels and checking the adequacy of their anchoring during shear: when the layers are mutually displaced. Experimental dependences “shear condition - compliance” are obtained for flexible bonds anchored in concrete layers and the ultimate force perceived by them is determined. The acceptability for thin reinforced concrete elements - layers of three-layer panels of standardized methods for calculating strength is checked. The effect of the joint work of layers on the load-bearing capacity due to flexible connections and insulation has been experimentally studied. The influence of shear span and transverse reinforcement on the bearing capacity of three-layer reinforced concrete structures with a middle layer of low-strength lightweight concrete monolithically bonded to the outer bearing layers is studied. Experimentally substantiated proposals for the calculation of bending reinforced concrete three-layer structures for strength have been developed.
