The peculiarities of the primary visual inspection of winter wheat seeds are considered. In the North-East of Ukraine, three groups of abnormal seeds (wrinkled, small seeds, and with a black point) were being identified by macroanalysis during 2017–2022. Factors affecting the representation of these groups in the samples were ana - lyzed. It was determined that the amount of abnormal seeds is determined by the growing conditions of wheat, the place of cultivation and spraying of wheat with fungicides. The maximum number of substandard seeds was noted in Polissia, where black point dominated. In the Forest-steppe, the largest amount of such seeds was recorded in 2022, among which small seeds prevailed. A study of the characteristics of the manifestation of a black point showed that the blackening of the embryo occurs only from above. A seed with a black point is usually mature. For the first time, it was proven that spraying plants with essential oils of cinnamon and fennel leads to an increase in the appearance of the black point, which once again confirms its abiotic nature. The study of the germination of externally healthy and abnormal seeds of the Bohdana variety of the 2018 and 2019 harvests under conditions of low temperature and over moistening showed better indicators for the first group. But the germination of abnormal seeds had contradictory results, especially in different years. Comparison of the germination and development of seedlings from healthy and blackening seeds under favorable conditions during different periods of storage of wheat samples, from different places of cultivation, on different genotypes gave new unexpected results: higher in - dicators in the variant with black point. During further study in conditions of low temperature, which is explained by very late sowing of winter wheat in recent years in Ukraine, completely different data were obtained. Seed germination was better in healthy seeds. Seedlings developed faster at first also from healthy seeds, but on the last two dates of measurement, they began to grow faster from seeds with black point.

The paper presents selected outputs of the scientific research activities of its authors in the field of implementation, intensification, and standardization of environmental management systems for technological enterprise practice. Aspects of environmental-economic continuity were examined in assessing technological inputs in the form of cost accounting for material and energy flows and the level of environmental quality of transformation processes in the input-output enterprise system. On the basis of these aspects, a model for accounting for the costs and revenues of individual processes was proposed and standardised. The methodological approach to cost accounting consists of ten key elements arranged in Deming’s cycle of continuous improvement with a closer specification of their purpose, function, and content. The basis for modelling and quantifying material and energy flows is the determination of input/output points, processes, and the determination of quantification nodes for evaluation in physical and monetary units. For each quantity node, costs for the system and waste management must also be quantified. Energy costs, system costs, and waste management costs are divided into product and material losses from production cost data for each quantity node. Summarisation and integrated presentation of cost data were proposed to utilize cost matrices and Sankey diagrams. Further benefits of using environmental cost accounting for material-energy flows in production were also specified.

The article examines the potential of buckwheat cultivation as an ecologically oriented crop, which, due to its biological and economic characteristics, can generate profits and contribute to improving the ecological state of production. Buckwheat, being a high-yielding and environmentally friendly crop, has the potential to become an important component of the agricultural sector. Currently, it may not yield as high as corn, sunflower, or soybeans, but buckwheat cultivation allows for profit generation that surpasses most other grain and legume crops, particularly when compared to winter wheat production. Due to its unique properties, buckwheat is valuable in many aspects: it can be used as a soil precursor and improver in agriculture, is an important source of honey, and contains many nutrients that can be utilized to create functional products with medicinal and health properties. The use of organic cultivation methods and the application of organic biostimulant fertilisers, such as “Vermimag”, can significantly improve the growth and development of buck - wheat, increase its competitiveness, yield, and the economic efficiency of organic production. According to research results, the best conditions for the growth and development of plants, increasing branching and the number of inflorescences, fruit set, and productivity of buckwheat were achieved by combining buckwheat seed treatment with two-time spraying of crops with the organic fertilizer “Vermimag”. Variants where organic fertilizer was applied showed better development of buckwheat plants, increased branching, and ultimately increased buckwheat yield.

In the context of climate change, the risk of flooding is becoming an increasingly global concern. In addition, natu - ral factors, economic development and urban expansion are significant contributors that have generated a strong demand for the management of natural risks, especially in the domain of floods and inundations. This research aims to address the issue of flood risk management in the Oued Martil region, specifically within the cities of Tetouan and Martil in the western part of Northern Morocco. In this regard, this study focuses on evaluating the performance of hydrological analysis of the Oued Martil plain and modeling flood flows in the Oued bed and in the plain overflow area. The results of this study show that the risk of flooding is significant in urbanized and densely populated areas (with high vulnerability) that match with zones with high or moderate hazard. Conversely, the risk of damage is lower for forests situated in areas with low or moderate hazard. The results obtained from hydraulic modeling can assist decision-makers in selecting the types of interventions for floodplain development by providing a comprehen - sive understanding of Oued Martil’s behavior during the exceedance of peak flow rates for different return periods.

Utilizing the primary field data collected concerning bathymetry, topography, and ocean parameters, a numerical simulation analysis (DELFT-3D) was conducted. A comparison between the numerical model of outcomes and the existing field data suggests a reasonable alignment regarding hydrodynamic factors. Several mitigation strategies were tested during the simulation study, taking into account their effectiveness, cost-efficiency, durability, and ease of installation. After careful consideration, the ‘perched beach’ concept has been selected as the most suitable op - tions. This mitigation measure consists of three key elements. Creation of a perched beach stretch of desired width along Ramakrishna Beach Road was carried out by sand nourishment. This nourishment can be sourced from Catamaran Beach Bund, where the required quantity of sand is presently available and is likely to be replenished naturally during NE monsoon. The transport of sand from catamaran beach to RK beach stretch can be done by a land-based pipeline. Installation of a 2 km long ‘Sill’ is required to retain the nourished sand from sliding into steep slopes in surf-zone. This shall be a geo-synthetic tube filled with sand to act as retaining structure up to 2 m depth. This operation is season-independent as the sill can be installed from land-based pumping of slurry. Installation of 2 km long submerged artificial reef to reduce the wave energy incident on the beach will aid in beach building process over the seasons. This shall be made up of artificial concrete blocks like tetrapod laid over a width of 12 m and a height of 2 along 3 m depth contour and smaller in shallow waters.

The research was aimed at evaluating the content of heavy metals in the ash of solid fuel pellets and various types of sorted and unsorted solid household waste. It highlighted the growing challenge of solid waste disposal and the potential of waste-to-energy technologies, and emphasized the importance of understanding the composition of fly ash due to its potential hazards. The research method involved the analysis of urban waste samples and their comparison with solid fuel pellets. The main findings revealed differences in chemical composition, with special emphasis on the presence and concentration of heavy metals. The highest concentrations of metal ions such as copper, strontium and lead were recorded in rubber, unsorted garbage and plastic. In the mixture of household waste of the Rybny landfill, such elements as: copper (Cu) – 0.141%, strontium (Sr) – 0.061%, and lead (Pb) –- 0.016%. Studies show that Zn, Cu, Sr, Pb are the main threats in solid waste ash. Given the potential danger of these elements, the ash generated after incineration of solid household waste requires special handling and disposal (Retrieved, 2018, Perfect Publishing, 2015).

This study delves into the influence of varying solvent compositions on the extraction of total phenolic compounds (TPC) and the antioxidant activities of extracts from Mentha suaveolens subsp. timija leaves and stems. The extraction process is conducted using ultrasound-assisted extraction via an ultrasonic bath. Employing a surface mixture design approach, we explored the singular use of water (W), methanol (M), and ethanol (E), as well as their combinations. The outcomes demonstrate that solvents’ compositions significantly influence the extraction of TPC, with noteworthy synergistic effects observed in specific combinations, such as a ratio of W:M (1/2:1/2). The scavenging activity of DPPH and the total antioxidant capacity (TAC) were also evaluated, indicating that certain combinations of solvents, particularly those involving methanol and water, enhance the antioxidant activities. The results reveal that solvent compositions significantly influence TPC extraction, with notable synergistic effects observed in specific mixtures, such as W:M (1/2:1/2). The Pareto chart analysis highlights the substantial contri - butions of methanol, ethanol, and water to TPC recovery and antioxidant activities. The findings underscore the importance of solvent optimization for extracting bioactive compounds, providing valuable insights for researchers and industries seeking to harness the full potential of this species in various applications.
