This article, based on archival documents and newspaper articles, studies the everyday life of the population of Tsaritsyn in the revolutionary 1917. Documents of Tsaritsyn's City Council stored in the State archive of Volgograd region clearly show the position of the different layers of the population, their reaction to the fall of autocracy, political events, social and economic situation in the city. The main focus is placed on the most important changes in various aspects of everyday life of the citizens: Rising prices, more acute shortages of food and fuel, deterioration of sanitary condition of the city, the degradation of the system of education and medical care. The article also describes drunken pogroms and rising crime in 1917. It is concluded that revolutionary euphoria and enthusiasm prevailing among the population during the summer of 1917 gave way to disappointment, discontent and struggle for survival. The workers and soldiers played a special role destabilizing the social, economic and political situation as they constantly put forward new demands for raising wages and to improving the supply. Meanwhile, new city authorities were unable to cope with socio-economic difficulties.

The article discusses the problem of protecting the foundations of buildings and structures constructed on coastal bases and subject to destruction under the influence of abrasion and erosion-landslide processes. The problem is vital for the cities of the Southern Federal district. Almost all settlements on the banks of the Volgograd and Tsimlyansk reservoirs and the rivers Volga, Don and Ahtuba are situated in the hazardous areas. The results of a study of hydrological and geological conditions are based on the monitoring processing of the shores of reservoirs and rivers of the Volgograd region. The research is based on the application of new scientific and the methodological principles of lithomonitoring. The results of the research must have a methodical and information basis for the establishment and functioning of the monitoring system of ecological safety and protection of the coastal areas of the Volgograd region from destruction on the basis of GIS-technologies. © 2016 The Authors.

Problems of sewer pipelines arising due to corrosion and biofouling are analyzed. Currently used methods of corrosion control of steel pressure pipes are designed to eliminate the consequences rather than the causes of surface oxidation. The task of preventing or achieving the lowest possible corrosion damage intensity is to ensure maximum efficiency of the pipeline protection which will increase as a result of economic indicators of the systems under consideration. Contemporary sewage pipelines represent a complicated complex of interrelated structures where various physical, chemical and biological processes take place. The implementation of such processes is not controlled and is accompanied by considerable costs connected in particular with pipeline replacement, repair of the sewage wells, reimbursement of harm done to water handling facilities. Recommendations about the prevention and the protection against the corrosion of existing and sewer pipelines that are being designed are provided. © 2016 The Authors.

This article concentrates on the aspects of assessment of reliability of organizational and technical decisions in construction processes, using computer-aided technologies. The methodical approach and algorithm of the software module solving the problem of evaluation of organizational and technical reliability of construction and design processes with a given level of reliability are presented in this article. A special feature of the approach is separation of the sample values of a random value (initial for determining the intensity and duration of the construction process-time rates per unit volume of works or performance) into two parts of values: those satisfying the conditions of the construction process on scheduled date and unsatisfying ones. This allows, in respect of the appropriate value for the initial design parameter, calculating the probability that rates or performance, and therefore the corresponding values of intensity and duration of the construction process at the end of implementation of the construction process time would not be more or less than the design values. This approach reveals a possibility of constructing algorithm to solve a set task by means of computer technology presented in the article. Based on the proposed algorithm, a software module was developed with the Technologist software package in order to solve problems of designing of building production on variant and probabilistic basis. © 2016 IEEE.

The paper presents new thermal design of external wall S. Radonezhskiy temple in Volgograd is developed according to author's concept. The three-layer brick wall, including a thermal insulation layer from concrete with polystyrene aggregates, is considered. Calculation of interstitial condensation in building component is carried out according to simplified calculation method developed by the author and harmonized to ISO 13788. Analysis of calculation results shows that condensation occurs at one interface during some months but there is no accumulation over the year as all the condensate is predicted to evaporate again. Thus, there is no systematic moisture accumulation at the building component within a year. The risk of run-off from non-absorbent materials will be very low. Analysis of the evaporation rates at the interface shows that duration of drying wetted layer in external wall during initial stage does not exceed admissible values. © Owned by the authors, published by EDP Sciences, 2016.

The paper describes an evaluation of thermal performance of residential building envelope. Basing on the visual-andinstrumental inspection the conclusion on the non-compliance of the stated object with the requirements of the design and normative documentation was drawn. The thermovision control allowed revealing latent defects of the buildings envelopes and outlining the ways of their elimination. The numerical modeling of heat transfer made it possible to reasonably develop suggestions aimed at enhancing the thermal performance of buildings envelope elements. The integrated application of these methods gave an opportunity to determine the thermotechnical state of the object in whole. The results of the study serve as a basis for the development of methodological foundations for design, construction, operation and reconstruction of energyefficient buildings. © 2015 Published by Elsevier Ltd.

This paper is devoted to the solution of an actual problem - energy saving and increase of energy efficiency of buildings. The express method of settlement and experimental control of energy saving on the basis of the specific characteristic of thermal energy consumption for heating and ventilation was developed. Advantage of the method is that it allows assessing the efficiency of a complex of energy saving actions without measurements of summary solar radiation under the valid conditions of overcast and domestic thermal emissions at comparable to GOST 31168 accuracy of results. On the basis of the developed method assessment of efficiency of a complex of the energy saving actions realized in an operated multicompartment residential building was made. Based on the results of the conducted pilot researches it was established that the specified building met the requirements for energy saving according to the SNIP 23-02, a class of energy saving for the building was C (normal). Method was tested on the results of the pilot studies executed for the same building in accordance with GOST 31168. Approbation confirmed the reliability of the results received by an offered method. The method can be used during the monitoring of energy consumption and the energy audit of buildings.

The propagation of bipolar electromagnetic pulses in an array of semiconductor carbon nanotubes has been investigated. The inhomogeneity of the pulse field along the axis of the nanotubes has been taken into account for the first time. The evolution of the electromagnetic field and charge density in the sample has been described by the set of Maxwell's equations and the continuity equation. The possibility of stable propagation of bipolar electromagnetic pulses occurring in an array of nanotubes has been demonstrated by numerical simulation. It has been shown that the propagation of the electromagnetic pulses induces the redistribution of the electron density in the sample. © 2013 Pleiades Publishing, Ltd.

Cellular concretes have become promising materials for the construction. The increase in the cost of energy resources, the thermo technical requirements for enclosing structures, a simple enough technology, the ability to obtaining single-layer protecting designs, technical and economic indicators confirm the high efficiency of cellular concrete as a wall material. Producing non-autoclaved curing foam concrete, reinforced with low modulus synthetic fibers is possible due to considering the technological role of dispersed reinforcement. Dispersed reinforcement influences the increase in the bearing capacity of the freshly prepared foam concrete mix, resulting in the elimination of destructive processes, increasing the dimensionally stability and raising its stability right after pouring it into the mould. The rate of plastic strength increase during the infusion of synthetic fibers by 1% by increases 2-4 times compared with the initial matrix. © 2016 The Authors.
