The authors of this article raise the issue of the correct selection of internal material for sandwich panels. The use of these structures is widespread in the construction of industrial facilities, so it is important to consider all the parameters of possible options for the optimal choice. The authors define the objectives of the article as the creation of an auxiliary comparative table with the parameters of the most popular thermal insulation materials for sandwich panels based on regulatory and theoretical information, as well as the formulation of recommendations for the use of a certain material depending on the specified conditions. Particular attention in the study is paid to such properties of materials as moisture resistance, flammability, durability, density and thermal insulation. It is also important to note that the article touches upon the cost issue, namely, market prices for sandwich panels are compared with the considered insulation materials of some suppliers.

The paper presents the concept of an intelligent superstructure designed to combine automated vertical storage systems, mobile robots and standard control systems for both warehouse and production processes into a single complex. The proposed mathematical model describes the key aspects of product placement, robot routing, and accounting for equipment throughput. Optimization algorithms allow you to create and quickly adjust storage and relocation plans based on dynamic changes (spikes in demand, disruptions, priority orders). The simulation results confirm that the implemented system helps to reduce time and resource costs, increases throughput and ensures higher adaptability of logistics operations.

The article is devoted to the analysis and optimization of the stability of engineering structures to wind loads through the use of innovative structures of support and anchor foundations. In modern construction, when the requirements for reliability and stability of buildings have increased, special attention is being paid to the development of effective foundations capable of withstanding both compressive and pulling loads. Support and anchor foundations are presented as a comprehensive solution, including combined anchors and a monolithic slab (grillwork), ensuring uniform load distribution. The main focus is on the combined anchor, which acts as the main working element that receives the forces from the structure and effectively transfers them to the ground. Unlike traditional piles, the proposed design significantly increases the resistance to pulling due to the use of wire anchors with high load-bearing capacity.

The article presents the development of an analytical hydraulic model of the side branch pipe of a three-way fire branch DN80. The relevance of the work is due to the need for accurate hydraulic calculation of fire water supply systems, the effectiveness of which directly depends on the correct assessment of pressure loss in the fittings. The model is based on the method of element-by-element calculation, which takes into account local hydraulic resistances in areas with a sharp change in the flow geometry. The model includes losses at four bends (three at 45° and one at 90°), a straight-flow valve, and sudden expansion and contraction sections. The contribution of linear head losses, similar to the central branch pipe, was considered insignificant, accounting for only about 6% of the local losses. This confirms the key role of local resistances in determining the overall head loss in this element. The model was verified by comparing the calculated data with the results of experimental studies. It has been established that the discrepancy between the theoretically calculated value of the head loss (6.86 m) and the experimental value (6.97 m) is minimal, with a difference of only 1,6 %, indicating the high accuracy and adequacy of the developed model. The key practical result of the study is the calculation of the total coefficient of local resistances for the lateral branch pipe of the fire branch, which was found to be ζ = 3.4. This value can be directly used for simplified and accurate hydraulic calculations of pump-hose systems with three-way branches.

The article is devoted to the analysis of methodological approaches to the definition and assessment of the psychofunctional state of a person. In connection with the need to improve the reliability of human-machine systems, the study of the psychofunctional state of a person controlling a dynamic object is of scientific interest, since to create reliable human-machine systems it is necessary to take into account the reliability factors of technical means and the human factor as well. The analysis of methodological approaches showed that to solve problems dedicated to increasing the reliability of "human-machine" systems, it is advisable to use a systems approach that considers a person not as an independent subject, but as an element of the system. The systems approach has a broad methodological base, allows us to study the psychofunctional state of a person in dynamics.

The physical model of the movement of liquids in capillaries proposed by Laplace and the Jurin formula obtained on its basis are in good agreement with the experiment in terrestrial conditions, but they are not applicable in zero gravity conditions. In this paper, it is experimentally shown that the capillary motion of a liquid is not caused by excessive Laplace pressure, but only by the forces of adhesion (Van der Waals forces) and cohesion. It has been experimentally shown that the phenomenon of capillary movement of a liquid over the surface of a solid body upon their contact occurs under normal conditions even in the absence of narrow slits or small-diameter cavities. The authors postulate a new hypothesis of the physical mechanism of the phenomenon of fluid movement on the surface of bodies, including in capillaries.

The article is devoted to the assessment of atmospheric air pollution in Rostov-on-Don for the period from 2019 to 2023. The assessment was carried out using a comprehensive indicator of atmospheric pollution for 5 pollutants (suspended solids, nitrogen dioxide, formaldehyde, sulfur dioxide and carbon monoxide). The main materials for the work were data obtained from the Environmental Bulletin of the Don and Yearbooks on the state of the atmosphere in cities in Russia. The dynamics of the city's atmospheric pollution over the specified period has been determined, as well as the territorial features of pollution and possible factors contributing to the current situation (the number of green spaces, the presence of enterprises, traffic flows). It has been established that the highest rates of atmospheric pollution are typical for the central part of the city, the most favorable environmental situation is in the east, and the western and northern parts are characterized by average pollution rates. A tendency of increasing atmospheric pollution has been established for the northern, central and western parts of the city, while the eastern part of the city is characterized by a gradual decrease in the content of pollutants in the atmosphere. The result of the work was the compilation of a map-scheme of atmospheric pollution in various parts of Rostov-on-Don.The main factors that determined the current environmental situation include: the volume of traffic load, the proximity of industrial zones and the level of landscaping of the territory.

This article presents a conceptual framework for assessing the maturity of construction control and supervision systems at construction sites. A multi-level assessment model has been developed, integrating the Analytic Hierarchy Process (AHP) and fuzzy comprehensive evaluation method. A five-level taxonomic system for grading the maturity of regulatory mechanisms in the construction industry is proposed. The procedures for forming a hierarchical structure of assessment indicators, constructing judgment matrices, determining weight coefficients, and applying the fuzzy comprehensive evaluation method to quantify the maturity level of supervision systems are described in detail. The developed methodology represents a universal tool for conducting comparative analysis of construction control and state supervision systems in various national and regional jurisdictions based on objective quantified criteria.

The article examines the features of dismantled paving slabs as raw materials for the production of recycled aggregate for concrete. The effect of crushed fine fractions of secondary crushed stone screenings on the properties of fine-grained self-compacting concrete was investigated. It was experimentally shown that the use of this material as a mineral additive leads to an increase in the water demand of the self-compacting fine-grained mixture and a significant decrease in strength.
