Annotation: This study examines the features of ensuring uninterrupted delivery of bulk materials required for the construction of roads, overpasses, and highways. The analysis covers technological and organizational aspects of transportation, logistics strategies, and supply chain management approaches in this field. Particular attention is given to the integration of digital technologies, such as IoT, ERP, and SCM systems, to optimize delivery processes, reduce costs, minimize losses, and enhance construction efficiency. Based on a literature review, the study formulates the hypothesis that implementing an integrated digital platform in the logistics of bulk materials can ensure the sustainability and quality of construction projects. The methodological framework includes a systematic analysis and a comparative literature review, allowing for the identification of a scientific gap. The findings of this study may be of interest to researchers and postgraduate students specializing in transport logistics, innovative construction technologies, and supply chain optimization, as it provides an in-depth analysis of uninterrupted bulk material delivery dynamics in the context of modern infrastructure projects. Additionally, the results may be useful for practicing engineers and experts in government regulatory bodies seeking to implement advanced methods to improve reliability and economic efficiency in large-scale road, overpass, and highway projects.

Annotation: Modern healthcare facilities face the problem of prompt maintenance of complex equipment, such as ultrasound, ventilators and CT machines. In conditions of limited access to qualified engineers, remote diagnostics via video communication is becoming a promising solution. This article examines the effectiveness of remote troubleshooting using video chats, analyzes factors affecting the accuracy of diagnostics, and proposes a standardized interaction protocol. The experiments included an assessment of various diagnostic scenarios, an analysis of communication quality requirements and the identification of types of breakdowns that can be eliminated without the physical presence of a specialist. The results showed that about 65% of faults can be correctly diagnosed remotely, provided that the conditions of a stable Internet connection and clear interaction with a technician on site are met. The developed technique allows to reduce equipment downtime and reduce service costs.

Annotation: Hair coloring is a complex biochemical process in which the acid-base balance (pH) plays a key role. The degree of cuticle opening, the rate of dye penetration, the stability of the pigment and the general condition of the hair after the procedure depend on the pH level. This article examines in detail how different pH levels affect the hair structure, the mechanism of action of different types of dyes and the quality of the final result. Research shows that highly alkaline formulations (pH 9–11) provide deep pigment penetration, but can damage the keratin structure. At the same time, slightly acidic dyes (pH 3–6) act more gently, but provide a less lasting effect. Optimum pH values vary depending on the type of dye and the desired result. Particular attention is paid to modern developments in the field of gentle coloring compositions that minimize damage without losing effectiveness. Methods of hair restoration after coloring are also considered, including the use of acid conditioners and protective agents.

Annotation: This study is a comprehensive analysis of the influence of fundamental laws of visual perception on the formation of compositional solutions in modern photography. The work examines in detail the neurophysiological and psychological aspects of image perception, systematizes the main compositional principles and their practical application in various genres of photography. Particular attention is paid to experimental data confirming the effectiveness of various compositional approaches, as well as to the analysis of cultural and historical aspects of the perception of visual information. The article contains detailed illustrations, graphs and diagrams that clearly demonstrate the dependence of viewer perception on the compositional techniques used.
