Published: June 2018

To investigate the effect of stimulation of human bronchial epithelial cells (HBECs) by arterial traffic ambient PM2.5 (TAPM2.5) and wood smoke PM2.5 (WSPM2.5) on the expression of long non-coding RNAs (lncRNAs) in order to find new therapeutic targets for treatment of chronic obstructive pulmonary disease (COPD). HBECs were exposed to TAPM2.5 and WSPM2.5 at a series of concentrations. The microarray analysis was used to detect the lncRNA and mRNA expression profiles. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis and gene ontology (GO) enrichment were conducted to analyze the differentially expressed lncRNAs and mRNAs. Quantitative real-time PCR (qRT-PCR) was performed to confirm the differential expression of lncRNAs. Western blot was performed to study the expression of autophagy and apoptosis-associated proteins. Flow cytometry was used to detect the apoptotic cells. The results indicated that fine particulate matter (PM2.5)-induced cell damage of HBECs occurred in a dose-dependent manner. The microarray analysis indicated that treatment with TAPM2.5 and WSPM2.5 led to the alteration of lncRNA and mRNA expression profiles. LncRNA maternally expressed gene 3 (MEG3) was significantly up-regulated in HBECs after PM2.5 treatment. The results of Western blot showed that PM2.5 induced cell apoptosis and autophagy by up-regulating apoptosis-associated gene, caspase-3, and down-regulating autophagy-associated markers, Bcl-2 and LC3 expression. In addition, we demonstrated that TAPM2.5 and WSPM2.5 accelerated apoptosis of human bronchial (HBE) cells, silencing of MEG3 suppressed apoptosis and autophagy of HBE cells. These findings suggested that the lncRNA MEG3 mediates PM2.5-induced cell apoptosis and autophagy, and probably through regulating the expression of p53.

Published: June 2018

In view of the high incidence of gastric cancer and the functions of hypoxia-inducible factor 1α (HIF-1α), our study aimed to investigate the functionality of HIF-1α in gastric cancer, and to explore the diagnostic and prognostic values of HIF-1α for this disease. Expression of HIF-1α in tumor tissues and adjacent healthy tissues as well as serum collected from both gastric cancer patients and normal healthy controls was detected by qRT-PCR. Survival analysis was performed using Kaplan–Meier method. HIF-1α siRNA silencing cell lines were established. Effects of HIF-1α siRNA silencing as well as PI3K activator sc3036 on proliferation, migration, and invasion of gastric cancer cells were detected by Cell counting kit (CCK-8) assay, and Transwell migration and invasion assay. Effects of HIF-1α siRNA silencing on AKT and VEGF were detected by Western blot. Expression of HIF-1α was significantly down-regulated in tumor tissues than in adjacent healthy tissues in most gastric cancer patients. Serum levels of HIF-1α were also higher in gastric cancer patients than in normal healthy people. Serum HIF-1α showed promising diagnostic and prognostic values for gastric cancer. HIF-1α siRNA silencing inhibited the proliferation, migration, and invasion of gastric cancer cells, while PI3K activator sc3036 treatment reduced those inhibitory effects. Down-regulation of HIF-1α can inhibit the proliferation, migration, and invasion of gastric cancer possibly by inhibiting PI3K/AKT pathway and VEGF expression.

Authors: Yuehui Wang , Xing Yang
Published: June 2018

The alternately stacking layers of SiO2 and TiO2 nanoparticles with different refractive indices were fabricated to form the distributed Bragg reflectors on the silicon wafer by dip coating method. By appropriate design of the thickness of the quarter‐wave layers, the peak reflectance region can be tuned from the blue‐green to the infrared portion of the electromagnetic spectrum. The peak reflectance of 65% at 800 nm and at 1600 nm has been achieved using seven periods, respectively; meanwhile, compared with the simulation, 80% at 800 nm and 70% at 1620 nm for seven periods, respectively. The scanning electron microscopy and the atomic force microscope studies confirm the thickness uniformity achieved along the fabrication direction, and a good quality of surfaces and interfaces.

Published: June 2018

One of the features ofGonyostomum semen, a bloom-forming and expansive flagellate, is uneven distribution in the vertical water column often observed in humic lakes. In this paper, we analysed vertical distribution of the algae in four small (0.9–2.5 ha) and humic (DOC: 7.4–16.5 mg dm−3) lakes with similar morphometric features with the aim to test the hypothesis that vertical distribution ofG. semenmay be shaped by zooplankton structure and abundance. In addition, we wanted to check whether high biomass of this flagellate has any influence on the chemical composition as well as on planktonic bacteria abundance of the water column. The results of the study showed that vertical distribution of the algae during the day varied among all studied lakes. Our most important finding was that (a) the abundance and structure of zooplankton community (especially in case of large bodied daphnidsDaphnia pulicaria, D. longispinaand copepodEudiaptomus graciloides) may shapeG. semenvertical distribution in studied lakes; (b) highG. semenbiomass may decrease the content of ammonium ions in the water column by intense uptake, but has low effect on other water chemical parameters. The results of the study contribute to the understanding of the factors influencing this expansive algae behaviour as well as it shows interesting aspects ofG. semeninfluence on some components of the lake ecosystem.

Published: June 2018

This article considers the influence of financial support on developing the territory`s touristic potential. Having applied economic-mathematical and statistical methods, the authors have analyzed the touristic and investment potential of Kirov region. They have come to the conclusion that the financing of developing the territory`s touristic and investment potential is performed mainly using the federal and regional budget funds within the framework of the approved Development Strategy of Territories, the share of private investment is rather small. Using the methods of logical qualitative judgments and scientific assessment on the basis of the existing Program for Tourism Development Program in Kirov region, the authors have offered a two-stage innovative scenario for developing the territory. This scenario relies on the available resource base and its development prospects on account of additional financing. Attracting additional investments in developing the touristic potential of Kirov region is possible due to the image promotion of the region, the popularization and enhancement of the status of events held on its territory, as well as the development of infrastructure facilities. In our opinion, the possibility to invest in developing infrastructure facilities is of prime importance as infrastructure facilities greatly affect the increase in tourist flow of the region.

The article provides of civil modeling of civil legislation development, shows its significance and peculiarities, structural elements, gives their characteristics, concludes the necessity of an integrated approach to Problem of civil models. For a long time, and to a large extent now, legislation, including civil law, is perceived as a means of legal regulation of public relations, and normative legal acts are considered mainly as the most important legal form of fixing and ensuring the proper conduct of the subjects. This "normative" approach, along with the positive ones, also contains a number of negative aspects, when there is a deep analysis of the draft legislation, the possibility and consequences of their implementation in practice, which often leads to the fact that the effectiveness of many normative acts remains low; there are many conflicts and cases of inconsistency in legislation; changes, additions and other, sometimes unsystematic, amendments to the legislation that give rise to a lot of discussions in the scientific and practical environment are constantly being made.
Management, mechanization and automation of work in the construction of high-rise buildings
Authors: Kagan Pavel
Published: June 2018

The construction of high-rise buildings consists of the implementation of known technological processes for the installation of building structures: foundations, walls, columns, etc. However, the features of these structures and the high-altitude factor on which the work is done predetermine a number of differences in the technology of production of works, which are manifested in the appearance of new or other accentuation of mechanization means, types of work, technological documentation. The most obvious differences of high-rise construction from the positions of the used machines, mechanisms and devices appear in the means for transporting goods and ensuring the safety of work at altitude. On the basis of the analysis of scientific and practical works in the field of design and construction of high-rise objects, the features of the organization and technology of production at these facilities have been determined. The main design solutions of high-rise facilities that affect the technological features of high-rise buildings are revealed. Features of managing the construction of unique high-rise objects are given. The general technological sequence of the investment and construction process for the construction of high-rise buildings has been determined. Specific features of mechanization and production technology for the construction of high-rise buildings in relation to certain types of construction and erection works are worked out (excavation, production of works of the zero cycle, concreting of the foundation slab, installation and finishing works at height, construction of the above-ground part and others).

Authors: Dement'eva Marina , Dement'eva Anastasiya
Published: June 2018

The paper presents the results of a study of the risk factors for the degradation of the urban ecosystem and their impact on the state of the objects of urban development. The purpose of the study was the development of a cartographic model for predicting the change in the technical condition of a town-planning facility, taking into account external factors. The relevance of the work is justified by the increase in the flow of failures of constructions and building systems, as well as the absence of a single system for diagnosing the risk of emergency situations. In the course of the study, the methods of mapping, structural analysis, the index method, and the method of expert assessments were used. The criterion for estimating the degree of influence of the operating environment on the exploited objects, which takes into account the quality of the medium and the decrease in the durability of the object, is proposed in this work. An example of the development of a forecast scale for the operating conditions of an object in the form of a matrix model is given in this paper. On the basis of the developed cartographic model, the cause-effect relationships between the intensity of failures on the exploited objects and the degree of degradation of the city's ecosystem were revealed. The model proposed by the authors can be the basis for adjusting the monitoring of technical condition, methods of protecting structures from destruction and optimizing the planning of preventive repairs.

The effectiveness of housing renovation programs in the Russian Federation
Authors: Kostrikin Pavel
Published: June 2018

The Housing Stock Renovation Program in Moscow, endorsed in 2017, caused a large number of public and academic debates on its quality and potential efficiency as well as (in more general terms) on possible methods of estimating the effectiveness of government and municipal programs implementation in the Russian Federation. The relevance of these discussions is predicated, among other things, on huge funds actually injected by the Russian government (especially on the national and subnational levels) into various links of the national development and construction industry. More than 1.74 trillion rubles were allocated from the Moscow budget alone for the financing of various construction programs in 2018-2020. Inquiring into the existing and prospective methods of decision-making in the process of development, approval, execution and assessment of the housing stock renovation program efficiency as well as suggesting practical recommendations in the given sphere were the main goals of the research undertaken by the author. Using the comparative analysis of several earlier completed government programs versus similar ones or the recently adopted Moscow renovation program, their goals and objectives, the author identifies, pigeonholes and compares their basic parameters and targets which were or weren’t actually attained. The undertaken research brings the author to the conclusion about the absence in the modern research, economic or practical circulation of any scientifically grounded methodology for ensuring a synchronous integrated real estate development and preset mechanisms of state participation in the investment and construction process, based, among other things, on bringing the target parameters of public (municipal programs) in conformity with their economic parameters.
Modeling of the investment project of construction the cottage settlement
Authors: Malyuk Vladimir , Danilov Aleksandr
Published: June 2018

During implementing any project related to improving the financial and economic activities of the enterprise, creating a new product or technology, significantly improving the quality of the product or service being produced, investments and, first of all, financial investments are needed. The proposed article attempts to consider the process of investing in the implementation of a construction project in terms of its optimization, or at least rationalization. It is clear that the solution of this problem by conducting an economic experiment in the course of a realistic project carries an increased risk of the company losing capital. This risk is virtually eliminated if the experiment is carried out on the model. Today, undeservedly little attention is paid to economic and mathematical dependencies, built on the basis of S-models. In this article, we give a detailed example of the use of S-modelling in determining the rational volume of investments in the project of building a cottage community, identify the opportunities and problems of using such models, and identify areas for further research within the framework of the proposed topic.

Authors: Valpeters Marina , Kireev Ivan , Ivanov Nikolay
Published: June 2018

The number of experts who realize the importance of big data continues to increase in various fields of the economy. Experts begin to use big data more frequently for the solution of their specific objectives. One of the probable big data tasks in the construction industry is the determination of the probability of contract execution at a stage of its establishment. The contract holder cannot guarantee execution of the contract. Therefore it leads to a lot of risks for the customer. This article is devoted to the applicability of machine learning methods to the task of determination of the probability of a successful contract execution. Authors try to reveal the factors influencing the possibility of contract default and then try to define the following corrective actions for a customer. In the problem analysis, authors used the linear and non-linear algorithms, feature extraction, feature transformation and feature selection. The results of investigation include the prognostic models with a predictive force based on the machine learning algorithms such as logistic regression, decision tree, randomize forest. Authors have validated models on available historical data. The developed models have the potential for practical use in the construction organizations while making new contracts.
Big data: perspectives of using in urban planning and management
Authors: Ivanov Nikolay , Gnevanov Maxim
Published: June 2018

To date, there is no doubt about the need and possibilities of using large amounts of information. So called “Big Data" technology is used in a variety of areas, and urban planning is no exception. The article discusses how to use large amounts of information for a competent design of social and engineering urban networks in the interests of cities residents while preserving historical appearance of cities. The proposed hypothesis states that urban planning can transition to a new higher level with the introduction of "Big Data" technology based on the concept of "Smart City", which not only makes the life of residents comfortable, but also allows making timely adjustments to one or other urban process with the purpose of its improvement. Additionally, possible approaches of the concept implementation and their applicability under various conditions are discussed. The article analyzes the experience of Smart City concept implementation as a part of "Big Data" technologies in practice of a number of European cities. Important positive results of such implementation are noted. The role and place of each of the parties interested in sustainable development of the city, in the development of intellectual systems for managing this development is discussed. In particular, a lot of attention is paid to the role of the state as the initiator and coordinator of interaction between the parties, the main holder and user of data, services and infrastructure. It is concluded that the potential built into the "Big Data" technology will allow us to move to a new level of urban planning, based on real urban data collected by various technical means.

In the present article we will consider a class of associative machines with dynamic structure where the entrance signal exerts direct impact on the mechanism of association of output signals of experts. At the same time we are interested in such group of expert decisions at which separate expert responses unite not linearly through hierarchically organized lock networks. Hierarchical mixture of opinions of experts, along with simple mixture are examples of modular networks: neural network of a module if the calculations executed by it can be distributed on several subsystems processing different entrance signals and not crossed in the work. Output signals of these subsystems unite the integrative module which exit does not possess feedback with subsystems. In fact, the integrative module makes the decision as output signals of subsystems are grouped in the general output signal of system, and identifies what examples are samples for training of concrete modules. The most general definition of modular neural network: any set of algorithms of data processing, including algorithms of the artificial neural networks grouped for the solution of some uniform task. Automatically determine the class of associative machines with dynamic structure where the entrance signal exerts direct impact on the mechanism of association of output signals of experts, at the same time group of expert decisions at which separate expert responses unite not linearly through hierarchically organized lock networks is considered.

In this article reengineering of processes of classification of objects in neural intellectual information systems of city development in the conditions of multi criteria approach is considered. The universal algorithm of calculation of cumulative total opinion of experts of the city district on the basis of a median of Kemeni who allows to order in the most reliable and objective way clusters rankings in the complex multilevel structures representing objects of municipal economy is offered. For receiving reliable results of an indistinct clustering it is necessary to reproduce the specified algorithm repeatedly at a certain number of clusters for various initial indistinct splitting and to compare values of criterion function of indistinct splitting which were received, for the purpose of adoption of the final decision on a necessary indistinct clustering.

The purpose of the study is to develop a potential mechanism for monitoring and motivating municipal authorities, based on the evolution of management of development processes. The paper describes the positive experience of management of local development processes on the example of the Bagrationovsky urban settlement, whose administration actively interacted with the pharmaceutical company “Infamed-K” located in Bagrationovsk. As a result, it was possible not only to ensure the participation of the settlement in various regional and federal programs on co-financing terms, fully pay off the past due debt that has occurred earlier, but also create a favorable living environment and solve many problems of the residents.
Criteria of the estimation of residential appeal of the territories in the construction of high-rise complexes

Lots of documents governing the construction, urban planning and territory improvement have been enacted a long while ago and basically give little consideration to changes going on and current state of affairs. They are mainly related to the average cost of living in the country. This necessitates the development of a methodical base of increasing the output of the work of construction. The basic criteria for the evaluation of the appeal of objects while constructing are high-rise complexes. A method for the calculation of land needs for the general plan of an investment construction project with a yard (or condominium). The research carried out showed that urban planning standards are not really stuck to, i.e. should be. On top of that, the objections of land adjoining property are the painfully missing.

A review of studies found that investments in construction have a multiple macroeconomic effect; therefore, these flows must be stimulated. However the study revealed that investments in construction in the Far North regions of Russian Federation including Murmansk region have suffered a decrease over a 20-year period, which has a negative impact on the infrastructure and the logistic system. Thus the goal of the research was to develop a strategic map for the sector’s development in order to increase its investment attractiveness. The paper suggests improving the investment attractiveness on the basis of the concept of a set of regional indicators, which is easily visualized by strategic maps. The proposed strategic map for construction sector of Murmansk region consists of four components: training, development and innovation; industry and entrepreneurship; society and market; regional finances and contains the key indicators characterizing each of the components. These components and corresponding indicators allow for regional authorities formulating the strategy of the sector development and monitoring the results of the strategy implementation.
