A new method for controlling the quality of technological products
Authors: Karmishin A M , Orlik L K , Zhukova G S 
Published: August 2020

Abstract
The problem of conformity of products to the requirements of technical control or between products of different batches puts the methods of experimental determination of product properties high on the agenda. The measurement of the parameters of these properties is stochastic. Some product properties can only be determined in specially designed experiments. Thus, in the production of powders, their dispersion can be normalized, the specific charge of condenser powders can increase, the location of magnetic granules of nanoparticles on information carriers can be controlled, the content of physiologically active substances in drugs can be controlled, and the spectrum of mobilities of atmospheric particles can be analyzed. Possible approaches to solving the problem of checking a batch of products for compliance with the requirements of technical specifications (TS) are considered using the example of powder dispersion. For the first time, a method has been proposed for comparing product properties, which are continuous random variables, by determining the joint area under their differential curves. The decision on the conformity of the measured product properties to the requirements of technical specifications is based on a comparative assessment with the directive established joint area under the distribution density curves. The technique of determining the probability of correspondence of normal distribution laws to each other is described. A final analytical solution is obtained for two exponential distribution laws.

Abstract
The paper discusses the modeling of the forces of interparticle pair interaction of spheroidal agglomerate in composite cement. Based on the calculation of the autohesion forces that make up the spheroidal agglomerate, i.e. the Portland cement (“carrier particles”) and silica fume (“guest particles”), it was found that for uncharged particles the magnitude of the electric interaction forces is negligible in comparison with molecular van der Waals and capillary forces. The bipolar charging of particles in the corona discharge field at a corona electrode potential of +18 and –18 kV sharply increases the electric component of the autohesion force, which in value approaches the value of capillary forces. In this case, the Coulomb attractive forces between oppositely charged particles begin to act before the direct contact of the particles, which contributes to the agglomeration of particles. These calculations are confirmed by the results of scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) of composite cement samples containing Portland cement (75 %) and dry gas purification silica fume (25 %), the number of angular particles of irregular shape decreases for a mixture of these materials processed in the device for surface modification.

Abstract
the article presents the study of the content of organic ecotoxicants – polycyclic aromatic hydrocarbons in the soils of the impact zone of the energy industry enterprise of Novocherkasskaya power plant (NPP) – the largest producer of electricity in southern Russia. The study showed a high level of total PAH content in the soils of the studied territory, compared to the background territories. The degree of contamination of soils in the zone of influence of the energy industry enterprises with Benzo(a)pyrene is classified as highly contaminated soils. The diagnostic relationships of individual PAHs showed a significant effect of the NchGRES on the soils of sites located along the line of the prevailing wind from NPP. For these sites, the pyrogen-coal origin of PAHs was established.

Published: August 2020

AbstractThe paper presents the results of the study of magnetic and magnetostrictive properties of rare-earth intermetallides based on TbFe2compound: Tb1-xZrxFe2, Tb1–xSmxFe2and (Tb1–xYx)0.8Sm0.2Fe2. These alloys have a cubic crystal structure of the Laves phase C15 throughout the substitution region. For the system of alloys Tb1–xZrxFe2the single-phase area is limited to the replacement parameter 0 < x < 0.2 and 0.8 < x < 1.0. The compounds of the Tb1–xSmxFe2system were studied via X-ray dilatometry. The magnetostriction of alloys within the Tb1–xZrxFe2and (Tb1–xYx)0.8Sm0.2Fe2systems was studied in the temperature range of 80-320 K in magnetic fields of up to 17 kOe via a strain-gauge method. It was found that each system has the phenomenon of sign inversion of magnetostriction constants: in the system Tb1–xZrxFe2in the area of replacement parameter x = 0.8, in Tb1–xSmxFe2- in the area x = 0.45, and in the system of alloys (Tb1–xYx)08Sm02Fe2at x = 0.6. It was demonstrated that magnetic compensation and spin reorientation phenomena occur in these systems. The obtained results are discussed in the model of alloys with competing exchange interactions.

Published: August 2020

Abstract
The literature on the deterioration of reservoir properties of the bottomhole zone during various operations in the wells and when acting on the reservoir is reviewed. It was revealed that bullhead well control operations and impacts on the bottom-hole formation zone have a very large negative impact if the current geological and physical conditions of the object are not taken into account. Laboratory and field tests of several hydrocarbon-based emulsion formulations were performed. Experiments and tests have shown the effectiveness of the proposed formulations and allow recommend them for use in well repair.

Published: August 2020

Abstract
The paper considers the issues of assessing the influence of various factors on the production of oil reserves of Jurassic deposits of Shaimsky oil and gas region. The study states the influence of the network of disjunctive tectonics dividing the deposit onto the network of blocks on the degree of oil recovery. Trace research was conducted. Dependencies showing that hydrodynamic connectivity between wells takes place along fault lines or close to them, which is caused by the formation of decompression zones with increased permeability, are obtained. It was found that in the central blocks of the deposit there are large effective oil-saturated thicknesses with higher reservoir properties, which does not allow faults with low displacement amplitude to disrupt the connectivity.
The choice of the correlating function of capillary pressure curves under conditions of reservoirs in Western Siberia
Authors: Akhmetov R T , Mukhametshin V V , Kuleshova L S , Mingulov Sh G , Malyshev P M 
Published: August 2020

Abstract
The article considers the approximation of capillary pressure curves of productive formations in Western Siberia. The relationship between the correlating functions of capillary pressure curves is shown: the Leverett J-function and the Brooks-Corey function. In this case, the Brooks-Corey function is the same Leverett function but used for water saturation of the effective part of the void space (reduced water saturation). The authors recommend choosing a correlation function for a given reservoir, depending on the tightness of the correlation between capillary pressure and volumetric or reduced water saturation. In this case, the Leverett function should be preferred, since it depends only on two parameters (permeability and porosity).
Modern specific of Japanese urbanism as a result of the country’s cultural mentality distinctiveness
Authors: Shevtsova G V , Gorbyk O O , Kubko A Y 
Published: August 2020

Abstract
The article analyzes the urbanistic experience of modern Japan in terms of the country’s architectural history. The following features of Japanese modern urbanistic are highlighted: dynamism and mobility – the ability of permanent development and modification (so called architectural metabolism); communicativeness of city space; the cohesion of the concepts of interior and exterior; freedom and novelty of architectural forms; humane and psychological comfort of urban environment. Based on the analysis of the unique climatic and seismological conditions of Japan, its geographical, ethnic and historical characteristics, it is revealed that all indicated above modern urbanistic features originate in the prerequisites of Japanese mentality formation directly related to architectural traditions. Since ancient times, Japanese culture has easily adapted to new circumstances modifying both obsolete traditional phenomena and foreign influences to a fundamentally different level. During the industrial revolution, thanks to the active borrowing of European and American engineering experience, such an approach leads in Japan to a qualitative leap of urbanism and design, forming an imaginary gap between the historical and modern architecture. In reality, urban planning and architecture of modern Japan demonstrate a deep genetic connection with historical tradition, which is present here as a permanent global evolutionary vector of ideas.

Published: August 2020

Abstract
The work is devoted to the study of the influence of folk architecture on the professional practice of housing design by modern architects. The study focuses on the use of traditional heritage techniques in the design of social housing in modernism in the period 1910-1970. The procedure of reproducing the experience of traditional (vernacular) architecture is described as a process of translation, which involves the decoding of folk heritage by professional architects in order to identify the characteristics and techniques relevant to the “modern movement”. The task of designing housing for the working class is observed throughout the period of modernism in various regional areas, from European countries and America to Egypt, Algeria and India. Historical analysis of the architecture of modernism helped to identify such valuable for its representatives’ qualities and properties of traditional architecture as: functionality, utilitarianism and archetypal. It has been proven that modernists were inspired by the architecture of traditional Mediterranean cities. It is shown that in the period of modernism, along with engineering innovations, architects introduced traditional design systems, materials, technologies and rethought their compositional potential, which significantly diversified the morphology of social construction and enriched its symbolic language. Thanks to the borrowing of traditional features, modern architecture has become clear to the consumer, and such morphological elements as a flat roof, white walls, simple rectangular columns and so on have become a new and quite understandable language of modern architecture.
Information Field of the Modern city silhouette
Authors: Martyshova L S 
Published: August 2020

Abstract
A modern city in all its aspects is a product of diverse information and semantic features that have been expressed in different ways in different times. Time continuum of urban existence and globalization are leading to universalization of rules and methods, on the one hand, and to the destruction of the identity and integrity of the landscape and architectural urban environment, on the other. They are demolishing the system of conceptual references and transforming historic time-tested cultural codes. Today the system information balance is intensively evolving under the influence of time and objective information reality, shifting historically tested and conventional highlights. The information field of the city silhouette is considered as integrity, having a universal algorithm and code, whose revealing and defining promote the recognition and proper interpretation of the most typical features of the contemporary urban environment in the city silhouette structure. The use of the algorithm and code as design and analytical tools for city planning enables to create integrated structures and unify conceptual information on the city silhouette, which form the system of landmarks for human world perception.
Types of ecological relationships in the system “nature, artificial environment, humans”. Peculiarities of modern eco interior development
Authors: Zymina Svitlana 
Published: August 2020

Abstract
The article addresses the main ecological trends of the environmental protection in the field of architectural design and construction, which are united under the common name of eco-construction. The article analyses various types of environmental relationships according to the degree of harmfulness of their impact on the artificial environment, nature and humans because of their construction activities. A graphical model is proposed, which clearly demonstrates how ecological relations (harmless, conditionally harmful and harmful) interact with nature, humans and the artificial environment. The human being as a component in the chain of relationships is present in all these spheres; in the artificial environment factor - as motivation and the main driving force, and in the natural factor - as part of its creation, it always balances between nature and the artificial environment. The search for a solution to the global environmental problem has led to the emergence of such concepts as ecological interior and eco-style. Based on the author’s classification, the peculiarities of the formation of a modern ecological interior are explained. The difference between the concepts of ecological interior and ecostyle is revealed, a new kind of ecostyle is proposed in the classification of eco-directions - pseudo-ecostyle, its features are considered.

Innovations in the Architectural Environment: the Impact of Society on the Positive Perception and Conflict of the Incomprehensible
Authors: Mezhenna Nataliia , Filippova Daria 
Published: August 2020

Abstract
The article is focused on issue of human perception of new objects of architecture and design, overcoming people’s commitment to the old and familiar. New ideas often face a negative reaction from society. Modern architecture, any projects of modern style, cause not only curiosity in its viewers but irritation, stress, negativity, psychological aversion as well. Original and common information of perception of the architectural environment is characterized by a dialectical unity. With complete originality there is a conflict of the incomprehensible. With complete commonness – the conflict of oversaturation. Unapprehensiveness generates the transfer of functions, the transfer of an object to another functional group. The more developed the society and the specific observer are, the easier it is to perceive new forms and technologies for them. There is a larger amplitude scale at the stage of information filtering. The development of society brings perception to a new stage, new forms and styles transform into typical ones, a psychological adaptation occurs. Crisis situations in a country and the general perception of life as critical, non-positive notion forms a negative reaction to new proposals. The situation is similar to “Seligman’s dogs”, the so-called learned helplessness. The psychological impossibility of non-action is the impossibility of thought, the unwillingness to look for analogies and images that would lead to metaphorical matches. Often the perception of a new object can be influenced in advance by technologies and mass media. In order to resist these technologies, to have his own, personal opinion, a person needs a high level of knowledge, world outlook, synthesis of information about the object. The formation of new human values, raising living standards lead to an adequate perception of the new architectural environment.

Published: August 2020

Abstract
The article analyses the origin and development of helicourts [1,2]. This is the new type of constructions which located on top of the roofs of skyscrapers and designed for users of air transport. Historical analysis was performed on the topic of cities design within the vertical plane, including the idea of traffic separation. The modern tendencies of how this issue is resolved were analyzed on the example of São Paulo and Kyiv. It is established, that in modern metropolitan areas there is ongoing new technological revolution, which aims at a radical change of transportation mode in cities, leading to the emergence of the modern aircraft. The main principles of formation of helicourt design decisions within the structure of high-rise buildings in metropolitan areas are: structurality, dominance and form. It has been determined, that the preservation of historical development, natural areas, and improvement of both transport connectivity and the environment where human activity is concentrated in cities can be solved by the introduction of a complex of structures that serves helicopter aviation, and that are located within the structure of multi-storey buildings.

Abstract
The innovative concepts of Jacob Steinberg, one of the leaders of constructivism architecture, the head of the Society of Modern Architects of Ukraine (OSAU) are considered. The projects of J. Steinberg by the purity of functionalist literacy are comparable to the projects of leading OSA masters. Among Steinberg’s Kharkiv projects - recognized as masterpieces of constructivism - the Builders’ Club, the building of the Central Committee of the CP(b)U, a complex of the Kharkiv Civil Engineering Institute on Shatilovka, a residential complex on the Pushkinskyi entrance. The unique Steinberg’s objects, that were revolutionary for their time, weren’t taken under protection and today they have been lost, rebuilt, or are in ultimate limit state. His legacy is still waiting for his collectors, organizers and researchers. Comprehensive research is needed, on the basis of which it will be possible to develop a strategy for documenting and preserving the Kharkiv objects of an outstanding Ukrainian architect. This applies to the possibility of complete restoration of the houses at the Pushkinskyi entrance, removal of distortions introduced into the building of the Builders’ Club during the post-war restructuring, graphic reconstruction of the lost Central Committee building and irreversibly rebuilt complex of ex. KhICE. The report discusses the prospects for the formation of citywide and national programs for research, documentation and preservation of the architectural heritage of interwar modernism.

Abstract
The article deals with the effect of micro-filler additives on the properties of high-strength concrete. The effectiveness of microcements – mixtures based on highly dispersed cement and silica fume – has been substantiated. Using the methods of thermokinetic analysis and thermoporometry, the processes of heat release and the formation of microporosity during the hardening of ordinary cement and microcements without additives and with the addition of silica fume are studied. The positive effect of silica fume on the hydration and formation of the structure of cement stone is proved. It is shown that the nature of the hydration interaction in the system of “microcement - silica fume” contributes to the compaction of the structure and reduce the development of shrinkage phenomena. It was revealed that the use of microcementives allows to increase the workability of concrete mixtures and to accelerate the rate of curing of high-strength concrete. According to the results of the studies, the high efficiency of the use of components of the type “microcement – silica fume” in the technology of high-strength and durable concrete has been proved.
Contact formation mechanism between squeezed crystalline solids
Authors: Volosyuk M A , Protsenko E M 
Published: August 2020

Abstract
The mechanism was proposed and experimentally approved for the final stage of the high temperature contact formation after generation of closed pores in the contact plane. The mechanism is that the pores being healed by the dislocation-diffusion mechanism form assemblages of vacancy type prismatic dislocation loops which alternate with clusters of previously formed interstitial prismatic loops. Between the vacancy-type loops and interstitial ones the diffusion interaction is established resulting in recombination of defects with different signs, the contact formation, pore healing, and decreasing stress and dislocation density in the contact area.
