Item Assessment of the danger of using ultraviolet lamps in electrical systems(2024) Semenov, A. O.; Popov, S. V.; Yakhin, S. V.; Yeleussinov, B.; Sakhno, T. V.; Семенов, Анатолій Олексійович; Попов, Станіслав Вячеславович; Яхін, Сергій Валерійович; Сахно, Тамара ВікторівнаTo determine the photobiological safety of UV lamps, the following measurements were carried out: spectral irradiance, total actinic irradiance in the wavelength range of 200-400 nm, and irradiance in the UVA range (320-400 nm). These parameters were measured using the optical radiation system OST-300. The photobiological safety of LUF 40-1, LE 15 lamps and their radiation risk group are established in accordance with EN 62471. The levels of UV radiation generated by LE 15 low pressure discharge lamps at a distance of 0.25 m belong to the high risk group (GR3), and LUF 40-1 - in the group of insignificant risk (GR1). Calculations and recommendations on safe radiation doses when using lamps in electrotechnical systems of photobiological influence are given.Item Bactericidal Disinfection of Activated Carbon from Aerobic Microorganisms, Yeasts and Molds(2022-02) Semenov, A.

Seeds Sown under Organic Growing Technology(2023) Pylypchenko, A. V.; Marenych, M. M.; Hanhur, V. V.; Semenov, A. O.; Sakhno, T. V.; Пилипченко, Андрій Васильович; Маренич, Микола Миколайович; Гангур, Володимир Васильович; Семенов, Анатолій Олексійович; Сахно, Тамара ВікторівнаThe oil content of hemp seeds is controlled by the genotype and in the conducted studies did not depend on the growing technology; however, this factor had a synergistic effect with others. The protein content of hemp seeds during the years of research did not depend on weather conditions. Like other quality indicators, it had a slight variation, which indicates the significant role of the genetic characteristics of the varieties. On average, over the years of research, the protein content of the variants grown according to conventional technology was 25.2%, and according to transitional technology, it was 0.03% higher, which was within the limits of statistical error. The organic technology ensured the protein content at the level of 25.3%, and the use of the BioStymix-Niva microbial biodegrader - biodestructor contributed to the further growth of the indicator to 25.4%. The oil content of hemp seeds is not limited by other important characteristics, such as the yield of the hemp stems or the fiber content. Only the Glyana variety showed inverse correlations with plant height, hemp stems and seed productivity, they were of medium strength (r = -0.60 – -0.43). In the Zolotoniski 15 variety, only one inverse relationship was recorded, i.e. plant height (r = -0.57). No correlation was established between protein content and oil content in seeds. Correlations may change depending on other factors of cultivation, including weather conditions, elements of technology, etc., but the evaluation of varieties for cultivation according to these characteristics can significantly increase the efficiency of the production of cannabis products.Item Impact of Organic Cultivation Technology of Fiber Hemp (Cannabis Sativa L.) on Soil Agrochemical and Bioecological Properties(2023) Pylypchenko, A. V.; Marenych, M. M.; Hanhur, V. V.; Semenov, A. O.; Korotkova, I. V.; Laslo, O. O.; Marinich, L. H.; Пилипченко, Андрій Васильович; Маренич, Микола Миколайович; Гангур, Володимир Васильович; Семенов, Анатолій Олексійович; Короткова, Ірина Валентинівна; Ласло, Оксана Олександрівна; Марініч, Любов ГригорівнаResearch into the correlations among components of soil biota is of significant importance for effective management of agroecosystems in organic agricultural production. Organic cultivation technologies contribute to increased nitrogen and phosphorus content in the soil, while reducing levels of P2O5 and K2O compared to inorganic methods. The influence of organic residue decomposers on macroelement composition in the soil has been examined, revealing a minimal impact on their levels. Organic technologies promote an augmentation of microorganisms, although there is a potential risk of heightened disease pathogens. It has been observed that under organic cultivation conditions, there is more intense tissue degradation, potentially attributed to higher microorganism activity. Transitional cultivation methods yield lower rates of degradation in comparison to organic techniques. The impact of organic technologies on the quantity of earthworms, nematodes, and springtails in the soil has been investigated. Organic practices have shown to increase their population, creating a favorable environment for soil biological indicators. Particular attention is given to correlation relationships between microorganisms responsible for nitrogen and phosphorus accumulation and the fungal component. High correlation values (r = 0.72–0.89) underscore the significance of comprehending these associations when employing organic cultivation methods. The study of correlations among soil biota components in organic production presents a promising task for the effective utilization of resources and the assurance of sustainable agroecosystem development.Item Influence of UV Radiation on Physical And Biological Properties of Rapeseed In Pre-Sowing Treatment(2021-02) Semenov, A.
