Authors: Ambrosova G , Kruglikova A , Kulkov V 
Published: November 2020

Abstract
The main aim of the work is to study the natural and climatic factors influence on the degree of change in waste fluid temperature in open facilities, depending on the design features of the main facilities (primary sumps, aeration tanks and secondary sumps), indicators for the sewage treatment, as well as a year seasons. It should be noted that today waste fluid temperature influence on the processes of sedimentation and biological treatment has been studied and mathematically described quite well. The high convergence of theoretical result, obtained using these mathematical models in the design with production data, has been repeatedly verified and proved. The statistical data collection on STF operating of Novosibirsk and Iskitim (Novosibirsk region) on the changes in waste fluid temperature at different stages of its purification was carried out for a long time, covering all seasons of the year. Mathematical processing of statistical data made it possible to obtain multivariate regression models that could be used to predict the actual temperature of waste fluid, depending on the operating conditions of wastewater treatment complex.
Application of wavelet analysis for processing tomograms of narrow cracks
Authors: Likhachev A , Zerkal S , Likhachev N 
Published: November 2020

Abstract
The previously proposed method of increasing the visibility of cracks on tomograms obtained from X-ray sensing of sections of metal elements of building structures has been developed. A multiscale decomposition of tomogram lines is performed using the Haar wavelet basis. The detailed decomposition coefficients corresponding to the level of the assumed crack width are multiplied by a constant, the value of which is determined based on the noise level and the difference between the amplitude of the crack image and the surrounding background. In contrast to the previous work, where these parameters were assumed to be set, here we suggest the methods for its evaluating from the measurements. In particular, a simple formula is obtained that relates the variance of uncorrelated noise in the projection data to that of noise in the tomogram. The method is implemented as a computational algorithm based on which a computer program is developed. Numerical modeling was performed. The errors of the first and second kind were used toevaluate the effectiveness of the method determining whether a pixel belongs to a crack image. Binary classification was used for their calculation. Dependences of errors on the number of projections and the noise level on them were obtained. The results of the simulations showed that the use of the proposed method can reduce errors by 1.7-2.5 times.

Published: November 2020

Abstract
In recent years, the approaches to address the issue of whether an object is real estate have been developed, but this problem has not received a legislative solution, which, both is associated with a two-level system of real estate, land plots and objects; and the modern needs of civil real estate turnover and the interests of its participants. All these make it necessary to fix at the legislative level more and more new real estate objects, including complex infrastructure objects. The article deals with the issues of information support for infrastructure real estate objects that arise, conducting accounting and registration actions. It is shown that the most optimal model for accounting and registration actions in relation to a complex infrastructure object is the unified real estate complex (UREC) model, based on complex cadastral works. The purpose of the study is to consider the issues of information support for infrastructure real estate objects, for the analysis of accounting and registration actions and for identifying new opportunities and optimal solutions in the Unified State Register of Real Estate in order to provide consumers with fast and high-quality public services.

Published: November 2020

Abstract
The researches’ results show that it is possible to obtain a ceramic crock, which water absorption meets the requirements of facade ceramic tiles at a charge firing temperature of 1150 ° C, consisting of 60% low-melting and 40% refractory clay raw materials from deposits in the Novosibirsk Region. Additives influence nature of directed action was studied: wollastonite and cullet by the mathematical planning method of the experiment. It was found that the introduction of additives helps to improve the physical and mechanical properties of the ceramic crock. The introduction of 10% cullet allows increasing the tensile strength by 10.3% compression and reducing water 27.1% absorption. The amount of 15% wollastonite contributes to a greater increase in mechanical strength and a decrease in water absorption, compared with the control composition. The joint introduction of mineral additives leads to a decrease in tensile strength.

Abstract
This article describes the technology and automation of non-autoclaved aerated concrete production. The proposed technology differs from traditional technologies by joint grinding of raw materials, which reduces production costs and energy consumption. Automatic control circuitsfor mechanisms executing technological operations are developed. Statistical analysis and verification of a non-linear multiple model confirmed the adequacy of the model: all regression coefficients are significant at the accepted level; all equations are significant; Gauss-Markov conditions are met; model specification is consistent with experimental data. It is possible to choose a composition of mineral additives that would provide the greatest strength of the cement matrix, solving the optimization problem with an equation corresponding to a certain mode of cement hardening. Such technology allows to get competitive high quality wall material, to reduce the cost of production by reducing the number of technological operations, for example, dry grinding of raw mix components, energy consumption and equipment for dry components grinding. The presented technology is recommended for design and use in the production of non-autoclaved aerated concrete wall blocks.

Authors: Kolchunov V , Dem’yanov A , Naumov N 
Published: November 2020

AbstractThe physical essence of the “nagel effect” for main reinforcement in a spatial crack of reinforced concrete structures under the action of bending and torsion for the model of reinforced concrete structures deformation involves the formation of the first block and the second block of a spatial crack. The second block is located on the upper surface of the longitudinal reinforcement to the surface of normal stresses and the resultant force from crushing concrete and a special adhesion force to the surface of the reinforcement (and the additional effect of breaking the continuity) in the eccentricity to its center of the axis of the reinforcement for distributed variable bending moment (through the calculation of statically indefinable systems for the force method). It is important to allocate a special area of the left side for the longitudinal reinforcement in the first block of separation and the formation of a new longitudinal crack, which removes surface normal and tangential of stress adhesion. Consider the scheme-a beam with two fixed ends: to calculate it, take the main system obtained as a result of making a cut in the middle of the beam for given unit diagrams of bending moments: under the action of a vertical load; with linear displacements of the fixed ends (normal to the beam axis); with rotations of the fixed ends in construction mechanics.

Authors: Kazantsev Y 
Published: November 2020

Abstract
The paper is devoted to the search for hedonic markups for residential properties in the Novosibirsk agglomeration in 2020. Method of hedonic regression is being tested in relation to the Russian housing market, based on the experience of similar foreign studies. The object of observation is a typical housing stock, legacy of the Soviet economy and urban planning. The use of hedonic model of pricing for real estate objects is presented in the works of many foreign researchers, but they considered them in relation to local housing markets, which have their own specifics, so their experience is not applicable in Russia. Our obtained results in numerical terms are comparable with similar data of foreign colleagues. This study is methodologically based on the studies’ results of hedonic pricing, obtained by Russian scientists, using materials from the Siberian region. As a matter of fact, these studies were carried out in the early 2000s, and their results related to the early development of the real estate market in Siberia. Hedonic method was applied in the analysis of real estate prices in the Novosibirsk agglomeration in 2020, an attempt was also made to minimize the entire set of factors influence on an object price, focusing on the hedonic markup, such general scientific methods as the system approach as a general methodological principle of the study were used in this work, scientific abstraction, logical analysis, systematization methods, comparative analysis, hedonic regression (Hedonic regression method) was used in the calculations as a kind of hedonic pricing.
Interconnection between the level of people’s digital quality of life and investment attractiveness of Russian regions

Published: November 2020

Abstract
Digital transformation influenced not only economic branches and markets, but also people’s quality of life in different regions of the country. The purpose of the research is to evaluate people’s digital quality of life and to define its interconnection with investment capabilities of Russian regions. The authors measure digital component of people’s quality of life with a regional index including six subindices (digital skills of people, availability of digital goods for people, digital quality of working life, social sphere and services, state electronic services and safety of people informational activities). These subindices based on data from the regions of the Russian Federation were used to define the level of people’s life digitalization and to estimate the digital inequality with the application of R/P ratios and variation ratios during 2015 – 2018. This period corresponds to available data on information society and digital economy in Russian statistics. For all years of the considered period the first position is taken by safety of people informational activities and the last place belongs to digital quality of working life, social sphere and services. Digital inequality, based on four subindices, increased during 2015 – 2018. Results of research obtained with the use of econometric methods show complete or partial confirmation of connection: it is positive for investment potential indicators and the Russian regional index of digital component of people’s quality of life and its subindices. Government expenditures on the digital economy program in Russia have the worst result among other national projects. During the process of digitalization it is desirable to unite government investments, household expenditures and firm investments in order to improve regional programs performance and cope with possible disproportions.
Metal and iron construction in sacral space shaping
Authors: Gnatiuk L , Novik H , Melnyk M 
Published: November 2020

Abstract
The article considers the use of innovative materials in the European sacred space of the late 18th - early 20th centuries in particular metal structures as well as the structural basis of reinforced concrete. The chronological framework of stages of this process which consistently master properties of the new building materials offered by an epoch of industrial revolution is established: cast iron, malleable iron, steel, reinforced concrete. The desire to be “modern” in the formation of sacred space, which follows from the artistic decisions of the first consumers of steel and concrete in sacred buildings, is analyzed. The constructive advantages and disadvantages of new materials are revealed. Metal constructions and decorative elements that form a sacred space are presented. A comparative analysis of public spaces, both sacred and secular in terms of the use of metal structures. Possibilities of new materials which demanded aesthetic comprehension are presented. It was found that during the XIX century such comprehension in the architecture of sacred spaces took place in line with two approaches: traditional-aesthetic, when constructive elements made of new material were designed in traditional historical forms in line with the eclectic understanding of styles; and structural and technological, by inventing new design principles for new construction. It was found that in both cases the use of metal and reinforced concrete was a significant factor that influenced the formation of modern sacred space.

Published: November 2020

Abstract
Droplet-Based energy harvesting is one of the most recent techniques used to convert environmental mechanical energies into electrical energy. Despite unique properties like compatibility with MEMS fabrication and efficient performance in reduced spaces, their operation is limited by the negative effects of electrowetting. In presence of an external electric filed, the wetting state of a droplet can be a function of three factors: the properties of applied dielectric, the wettability features of the droplet, and the amount of applied electric filed. An appropriate circuit can manage the effect of external electric filed on the droplets which here is considered as a tool to mitigate the negative effects of electrowetting. This paper presents designing, modeling, and fabrication steps of a droplet-based power generator considering electrowetting during fabrication and evaluation processes. The generator operation was analyzed in a voltage-constrained circuit and the experimental data were in accordance with the proposed semi-empirical model in this regard. Generator evaluation was done using a range of capacities made by 12 to 84 droplets under frequencies of 0.8, 10.8, and 16.6 Hz and a bias voltage of 7.5 V. The maximum output voltage and power was obtained by applying 16.6 Hz frequency to 84 droplets, reaching 1.25 V and 1.56 μW, respectively.
Modelling non-linear consensus dynamics on hypergraphs
Authors: Sahasrabuddhe Rohit , Neuhäuser Leonie , Lambiotte Renaud 
Published: November 2020

Abstract
The basic interaction unit of many dynamical systems involves more than two nodes. In such situations where networks are not an appropriate modelling framework, it has recently become increasingly popular to turn to higher-order models, including hypergraphs. In this paper, we explore the non-linear dynamics of consensus on hypergraphs, allowing for interactions within hyperedges of any cardinality. After discussing the different ways in which nonlinearities can be incorporated in the dynamical model, building on different sociological theories, we explore its mathematical properties and perform simulations to investigate them numerically. After focussing on synthetic hypergraphs, namely on block hypergraphs, we investigate the dynamics on real-world structures, and explore in detail the role of involvement and stubbornness on polarisation.

Published: November 2020

Abstract
The study presents the dynamics of solid-state dewetting of silver (Ag)-film annealed in N2 ambient, analyzed by atomic force microscopy and scanning electron microscopy. Varying the annealing parameters (i.e. temperature and time) and Ag-film thicknesses were taken into account, to determine their effect over the solid-state dewetting of Ag-films. Several morphological evolutions from nanohole to the presence of metastable nanorings were observed. It was determined that structures annealed at high temperature (≥900 °C) and/or time (≥2 h) results in formation of metastable nanorings and whose geometrical aspects and population grew with increasing film thickness. Possible applications of the structures for fabrication of silicon nanowire arrays and photo-emitters are briefly described.
Religion: A Very Short Introduction
Authors: Tweed Thomas A. 
Published: November 2020

Abstract
Religion: A Very Short Introduction offers a concise and fair account of the vast topic of religion, incorporating insights from different scholarly fields while also respectfully representing diverse religions and varying viewpoints. Everyone who aspires to be an informed global citizen needs to understand religion, since it affects how billions around the world conduct their lives. But most overviews are too wordy or too partisan. This one focuses on the key questions: What is religion? What does it do? How is religion expressed and how has it changed? That story of change begins with the first signs of religion among ancient humans using stone tools, and it ends with modern adherents using computer technology. Religion continues to evolve, and it continues to play an important role in how people deal with recent trends and contemporary problems, from climate change to armed conflict. Religion, the author shows, is both intensifying and alleviating those problems. Religion is pulling us apart and bringing us together.
White Slave Fiction, So-Called
Authors: Fisher Laura R 
Published: November 2020

AbstractIn the early twentieth century, the widespread belief that young white women were at risk of being captured and forced into sex work led to significant legislative victories, and this crisis also shaped US literature in surprising ways. When writing about so-called white slavery crossed over from the spheres of journalism, social reform, and the law into fiction, authors devised a suite of quasi-empirical literary techniques that turned the dubious facts of white slavery into the stuff of popular art. Novelists drew heavily on juridical and social scientific evidence to lend authority and specificity to stories that they insisted (counterfactually) were gravely true. White slavery fiction marries empiricism with sensationalism, data with melodrama, cold statistics with exaggeration and falsehood. This essay examines the literary empiricism of Reginald Wright Kauffman’s 1910 novel The House of Bondage and the amateur literary criticism of progressive anti-vice reformers to examine a tradition of mutual borrowing between nonfictional genres such as the report, tract, and newsletter and modern US fiction. An analogy between slavery and forced sex work was pivotal to the social critique that white slavery novels existed to forward. Yet the genre’s catalyzing metaphor circulated a radically dehistoricized, racist conception of enslavement for a twentieth-century white readership, drawing its figurative vocabulary and sense of political urgency from chattel slavery while eliminating any concern with Black men, women, or children.
