Today, all over the world, the focus is on the use of the new technologies that would significantly improve the construction quality. The paper considers the low-rise construction development as a whole, analyzes one of the most promising areas of architectural and construction development in the world - modular construction, explores all the positive and negative aspects of modular buildings.

The article outlines the production of fibrous materials, discloses energy production targets for mineral wool items production, scrutinizes specific features of cupola process. Besides, the article presents the experimental research of mineral wool cupola process. Thus, the article describes the design of a cupola furnace, principles of its operation, and its main performance indicators. A summary of analytical and theoretical research of non-isothermal gas flow motion in shaft furnaces is presented herein. The results of the experimental studies of the patterns of change in gas-dynamic operation of the cupola furnace are also shown in the article. To assess the development of solid fuel combustion in the furnace, the laws that govern the changes in gas composition at the level of stockline have been studied. The results are shown in the Table. The analysis of the current state of thermal and gas-dynamic operation of the mineral wool cupola furnace yielded recommendations for optimization and performance enhancement of the operating cupola furnace.

In this review, we provide an overview of methods for synthesizing magnetic nanoparticles (MNPs) with potential applications to biomedical research. We explore how the structure and properties of these particles are related to their diverse uses in medical diagnostics and bioanalysis. Special emphasis is placed on MNPs containing noble metals, which serve as biomarkers or active agents. Specifically, we focus on the application of direct and combined methods of atomic spectroscopy (ETAAS, AES/ICP–MS) to biomedical research. Experimental approaches to studying the behavior and transformations of MNPs in vitro and in vivo are considered. The importance of proper sample preparation in simulating the behavior of nanoparticles in biological media is highlighted. We also examine the significance of preparation techniques for the accurate determination of dissolved and nanosized forms in biological samples. Lastly, we assess the potential for the comprehensive studies of MNP behavior within complex biological systems, pointing toward future directions in this dynamic and promising field of research.

This article proposes the new technology for development of operational states for HSS of arbitrary structure and dimension. Technology is based on multilevel modeling and a new method for adjustment calculation of thermal hydraulic states. It is implemented in the information and computer complex «ANGARA-HN». Technology includes checking the permissibility of states, calculating the throttling devices on the network and inputs of consumers’ buildings. It allows calculating large systems with intermediate stages of regulation, developing adjustment measures to improve the quality of heat supply and consumer provision, reducing circulation flow rates and pressure in networks. The development of modeling methods is carried out in the following directions: taking into account the new composition of equipment, including mixing pumping stations; development of nontraditional methods of calculation, such as object-oriented modeling; development of tasks of hierarchical optimization and identification of state parameters, as task of rising for model adequacy; development of task for finding of sectioning variants for multi-circuit heat network with several sources. The application of methodological and software developments makes it possible to obtain both an economic and a social effect by identifying and realizing of the energy saving potential, improving the quality and reliability.
