Назва: Innovative approaches to enhancing the safety and resilience of dairy products under market challenges Автори: Луговий, Сергій Іванович; Lugovoy, Sergey; Підпала, Тетяна Василівна; Podpalaya, Tatiana; Бондар, Алла Олександрівна; Bondar, Alla; Тимофіїв, Михайло Михайлович; Tymofiiv, Mykhailo Короткий огляд (реферат): Against the backdrop of increasing anthropogenic pressure on the environment, ensuring the quality of food products is becoming increasingly important as a key factor in safeguarding public health. This study focuses on improving dairy production processes through the implementation of integrated approaches aimed at enhancing microbiological safety at various stages of the technological cycle. The research assessed the impact of introducing technological and sanitary innovations on the quality indicators of raw milk and the economic efficiency of Promin Agricultural Limited Liability Company in the Mykolaiv Region during 2024–2025. The study evaluated the impact of probiotic feed supplements and improved milking equipment cleaning protocols on milk quality and economic efficiency in Holstein cows. The results showed a 47% reduction in total bacterial contamination and a decrease in somatic cell count from 390,000 to 210,000 per mL, leading to fewer losses during primary processing. The proportion of non-standard milk batches decreased by 31%. Improvements in microbiological stability were matched by better physicochemical parameters: density, freezing point, and acidity remained within regulatory limits, while protein content rose from 3.2% to 3.5%. The improved quality boosted the average milk procurement price by 8%, increasing profitability. Additionally, antibiotic use decreased, and economic analysis revealed a 15% reduction in detergent costs, 10% in energy consumption, and 30% in product losses. Thus, the implemented innovative solutions proved effective and can be recommended for use not only by dairy farm specialists but also by veterinarians, certification authorities, and researchers in the agricultural sector.

Назва: Scenario modeling of grain production potential in conditions of military risk: The case of Ukraine Автори: Zavadska, Yu.; Iatsenko, O.; Fiore, M.; Yatsenko, O.; Христенко, Ольга Андріївна; Khristenko, Olga Короткий огляд (реферат): This paper examines the transformation of Ukraine’s grain sector under the conditions of the full-scale war and its implications for global food security. Using annual data from 2000 to 2023, we forecast grain production potential for 2025–2026 carrying out ARIMA models (a non-seasonal specification within the SARIMA family). To support interpretation under heightened uncertainty, the results are discussed through three military-risk scenarios -low, medium, and high—that differ in the severity of constraints on agricultural operations and export logistics. The study finds that even under the high-risk scenario, Ukraine retains the capacity to supply over 5% of global grain exports. We argue that the key determinants of sector resilience include technological modernization, institutional support, and logistical adaptation. Additionally, an integrated scenario matrix is developed to link strategic priorities, implementation levers, and financing sources for grain-sector modernization. Four vectors for strengthening long-term resilience are identified: economic, technological, institutional, and European integration. The findings suggest that a coordinated, multi-vector strategy can help offset wartime losses and support Ukraine’s integration into the European market with higher value added and greater resistance to external shocks.

Назва: Emergency Household Water Treatment for Conflict-Induced Supply Disruption: A Case Study of Multi-Contaminant Raw Water in Mykolaiv, Ukraine Автори: Калініченко, Антоніна; Kalinichenko, Antonina; Ushchapivska, Tetiana; Honcharenko, Iryna; Гончаренко, Ірина Василівна; Hovorukha, Vira; Tashyrev, Oleksandr; Sporek, Monika; Patyka, Volodymyr Короткий огляд (реферат): Damage to urban water supply infrastructure can rapidly compromise access to safe water and force households to rely on alternative sources of uncertain quality. This study presents a case-based assessment of water quality and emergency household-level treatment options in Mykolaiv, Ukraine, following conflict-induced disruption of the centralized water supply system. Water samples collected from selected groundwater and distribution-network points were analyzed for physicochemical, organoleptic, and microbiological indicators, including total dissolved solids, hardness, sulfates, chlorides, iron, permanganate oxidizability, total microbial count, and E. coli. The results showed elevated mineralization, increased sulfate and chloride concentrations, high hardness, organic load indicators, and episodic microbiological contamination in several samples. A low-cost four-stage household treatment procedure combining chemical oxidation, thermal treatment, sorption, and short-term preservation was evaluated as a preliminary emergency approach. The procedure improved odor, taste, hardness, iron content, permanganate oxidizability, and microbiological safety; however, it did not fully reduce total dissolved solids, sulfates, or chlorides to drinking-water standards. Therefore, the treated water should be considered non-potable and suitable mainly for limited domestic and hygienic uses unless additional desalination or blending is applied. The study highlights both the potential and the limitations of simple household-level interventions under emergency water supply disruption and emphasizes the need for decentralized treatment support, monitoring, and long-term infrastructure recovery.

Назва: Analysis of Influence of Cylinder Shell Thickness on Distribution Character of Dynamic Characteristics of Free Vibrations Автори: Grigorenko, O. Ya.; Borysenko, M. Yu.; Бойчук, Олена Володимирівна; Boichuk, Olena; Sperkach, S.O. Короткий огляд (реферат): The free vibrations of circular cylindrical shells with various thickness-to-midsurface radius ratios and different combinations of clamped and hinged edges of the shell are studied using the finite element method. The dependence of the natural frequency vibrations on the increase in the shell thickness is analyzed. The symmetric and asymmetric modes of free vibrations, frequencies, and modes of the vibrations corresponding to bending, torsion, tension-compression, and shear deformations are considered. Significant attention is paid to validation of the reliability of the numerical results.
