Methods. To calculate the motorcycle motion model Matlab was used.

Findings. The methods have been developed for determining the coordinates of the center of gravity of a multifunctional fire and rescue motorcycle equipped with an equipment unit. The effect of motorcycle speed on its stability when turning around was researched.

Application field of research. The results of the work can be used in recommendations for motorcycles exploitation in case of moving to the fire place.

Calculation of the thermodynamic parameters of the reaction between acryloyl chloride and water by density functional theory

Huu Hieu Nguyen — 2023-08-10

Purpose. Study of thermodynamic properties of acryloyl chloride to predict the danger if the acryloyl chloride is extinguished by water.

Methods. Thermodynamic properties (including enthalpy, free energy, entropy and heat capacity at constant pressure) of acryloyl chloride at vapor phase at 1.0 atm pressure and temperature range from 298.15 to 1000.00 K in steps of 100.00 K are determined by DFT calculations using PBEPBE functional. As the basis set 6-311G++(d,p) is used.

Findings. Free energy, and heat of reaction between acryloyl chloride and water in the fire (at the same temperature range and pressure) have been calculated. In temperature range from 298.15 to 1000.00 K, the reaction between acryloyl chloride and water is exothermic. So, if firefighters use water to fight the fire of acryloyl chloride, a large amount of heat will be released. This heat makes the fire is more dangerous and difficult to fight.

Application field of research. The results of research can be used in prediction the hazard of burning of acryloyl chloride and ways of extinguishing it.

Features of the mechanisms of action of inhibiting and phegmatizing fire extinguishing compositions

Mark M. Zhurov — 2023-08-10

Purpose. To analyze the theoretical aspects of the mechanisms of action of inhibitory and phlegmatizing fire extinguishing compositions.

Methods. Analytical, comparative evaluation of the mechanisms of action of inhibitory and phlegmatizing compounds.

Findings. Comparative analysis of theoretical aspects of the mechanisms of action of inhibitory and phlegmatizing compounds. The energy relationship between the chemical reaction of combustion and the thermal theory of extinction is shown. The values of bond breaking energies for some combustible molecules and their radicals are generalized. The standard breaking energies of chemical bonds of halogen derivatives of saturated hydrocarbons and their fire-extinguishing efficiency are compared, which indicates the relationship of their nature with the fire-extinguishing effect.

Application field of research. Modern approaches to the development of fire-extinguishing compositions for the intended purpose. Development of innovative materials and technologies.

Interrelationships of the problem use of social networks by Belarusians with victimization, exposure to cyberbullying and manipulation

Viktor P. Sheinov — 2023-08-10

Purpose. To identify possible links between problematic use of social networks and victimization, exposure to cyberbullying and manipulation in the Belarusian society.

Methods. To assess the problematic use of social networks, the questionnaire «Dependence on social networks» was used, addiction to a smartphone – a short questionnaire CAC-16, a test for victimization, questionnaires on exposure to manipulation and cyberbullying were also used. Quantitative and qualitative methods were used for data processing.

Findings. Social networks have become widespread in modern reality. Excessive interest often leads to the formation of dependence on social networks associated with a number of manifestations of psychological distress. A set of mutually related phenomena – dependence on social networks and its adverse manifestations – is the basis of the construct «problematic use of social networks». The basis of the empirical study were the test results of 557 Russian-speaking Belarusian respondents. The article shows that the problematic use of social networks by both men and women is positively correlated with smartphone addiction and exposure to cyberbullying and negatively associated with age and exposure to manipulation, and in women it is also positively associated with victimization. The established correlations between the problematic use of social networks and exposure to cyberbullying confirm the results obtained abroad. The revealed inverse relationship between problematic social media use and exposure to manipulation is a new result. This relationship is due to similar relationships between the factors composing these constructs. The positive correlation of problematic use of social networks with victimization only in women differs from the fact that such a relationship has been established in foreign studies for both women and men. Such a connection is carried out by similar connections of most of the factors composing these complex constructs. The positive correlation between problematic social media use and exposure to cyberbullying and its negative association with exposure to manipulation suggests that exposure to manipulation is replaced by exposure to cyberbullying in problematic social media use.

Application field of research. The practical application of the study can be used in explanatory work on the prevention of addiction to social networks.

Virtual interactive training simulator «Gas mask checks»

Application field of research. The virtual interactive training simulator «Gas mask checks» is designed to gain knowledge and assess the formation of the acquired skills in correct use of the civilian gas mask GP-7 by employees of organizations whose duties include the use of personal respiratory protection equipment.

Legal basis of the fire safety audit system in the Republic of Belarus

Alena Yu. Goroshko — 2023-08-10

Purpose. Formation of legal proposals on the implementation of auditing activities in the field of fire safety in the Republic of Belarus.

Methods. General scientific methods were used: analysis, synthesis, generalization, induction and modeling, as well as private research methods: comparative legal and legal forecasting.

Findings. Legal proposals on the implementation of auditing activities in the field of fire safety in the Republic of Belarus have been formed as a result of the analysis of theoretical provisions, national and international experience in the implementation of the fire safety audit, namely: strategic audit directions have been determined; an audit algorithm for fire safety is proposed, requirements for organizations that have the right to carry out audit activities in the field of fire safety, qualification characteristics of the expert auditor, structure and content of the audit report are determined.

Application field of research. The prepared proposals on the implementation of auditing activities in the field of fire safety in the Republic of Belarus can be used in the preparation of regulations in this segment of activity, and in scientific research. The introduction of the formed legal proposals will make it possible to rationally and effectively build an audit system in the Republic of Belarus, involve business entities along with state fire supervision authorities in assessing the state of fire safety, and prepare additional resources in ensuring fire safety of the state.
