The studies were conducted under conditions of different levels of insolation and with different soil conditions. The species composition of the living ground cover was determined, the general projective cover of the living ground cover, the general projective cover of bryophytes, and the projective cover of each bryophyte species were established. The general and particular projective coverage of mosses was determined according to the methodology developed by us using information technology. The conducted studies have shown that the abundance and occurrence of epigeic bryophytes, as well as the dominance of mossy species in urban parks depends on the growing conditions. Bryophytes are less demanding on soil fertility, which leads to their dominance in conditions of serious disturbance of the soil cover or in its absence. Epigeic bryophytes of the parks Bryansk has a number of decorative characteristics, due to which they have a beneficial effect on the aesthetic appearance of green areas.}, year = {2024}, eissn = {2267-1242}, pages = {03013} } @article{MTMT:34775523, title = {Alternative approach to evaluate the data of ecological monitoring of ecotopes for highways in Ukraine}, url = {https://m2.mtmt.hu/api/publication/34775523}, author = {Kuzminets, Mykola and Dubovenko, Yurii and Lampeka, Mykola and Tymenko, Volodymyr}, doi = {10.1051/e3sconf/202450803014}, journal-iso = {E3S WEB CONF}, journal = {E3S WEB OF CONFERENCES}, volume = {508}, unique-id = {34775523}, issn = {2555-0403}, abstract = {We propose alternative approach to evaluate data from ecological monitoring of ecotopes along the roadways of Ukraine, taking into account raised accuracy of treating the ecological impact on the roadside environment. Methodology includes sources analysis, development of a workflow model for monitoring and identifying the main components of input data and their optimal features by system analysis. The monitoring of ecotopes of green plantations along highways in the steppe zone of South Ukraine increases the accuracy of evaluating the ecological trace on roadside environment and facilities. Scientific novelty of study combines various data sampling, physical equipment, and road measurements with information services (computing, analyzing and treating input data, forecasting of system development, and monitoring management through feedback control). The system analysis of data deals with the optimal linear constraints of the roadside ecotope capacity, leading to a simple mathematical model of the monitoring. The problem of processing environmental monitoring data with such data is reduced to the linear programming problem. Specifically, this mathematical model allows for the consideration few factors influencing the ecological situation and provides the ability to analyze and forecast the development of ecosystems along roads. Conclusions of study are criteria for an objective assessment of the degree of pollution of the environment and its impact on soil cover, vegetation and road equipment. For effective monitoring it is necessary data-based quality management system on highways. It helps evaluate the predicted degree of environmental pollution by degradation of soils, vegetation, and road facilities.}, year = {2024}, eissn = {2267-1242} } @article{MTMT:34753182, title = {Cytotoxicity of synthesized silver nanoparticles on breast cancer cells}, url = {https://m2.mtmt.hu/api/publication/34753182}, author = {Darmadi, Jason and Anwar, Ayaz and binti Shamsul Anuar, Nurshafida Adzlin}, doi = {10.1051/e3sconf/202448803022}, journal-iso = {E3S WEB CONF}, journal = {E3S WEB OF CONFERENCES}, volume = {488}, unique-id = {34753182}, issn = {2555-0403}, abstract = {Breast cancers are becoming harder to treat due to the acquisition of chemo-drug resistance.

This makes the estimation of solar power generation to be very difficult. This study presents a development of machine learning to model a solar power plant for estimating the generated power. The machine learning is developed by implementing the k-NN algorithm. A data set of power generated in a solar power plant is applied to build the machine learning. The development resulted in a machine learning that models the solar power plant. Simulation test result show the machine learning was able to estimate the solar power generated with an accuracy of 69.6%.

As a result of the research, it is scientifically based that the increase in the level of contamination of the soil is subject to the decrease in water permeability, and the decrease in the level of pollution is subject to the law of the increase in water permeability. In the article, weakly, moderately, strongly and very strongly contaminated soils with oil were studied. According to the results, it was determined that the water permeability of the soil was observed in 25, 45, 45, 37, 5, 3, 2 minutes, and it carried 75, 26, 44, 45, 540, 1050, 1200 ml of water, respectively, for 90 minutes. The amount of water transfer compared to the control soil for 90 minutes was less in 1%, 2%, 5% contaminated soils, and very high in 15%, 25% and 37.5% contaminated soils. The increase in the level of pollution is explained by the deterioration of water permeability and moisture retention. Also, due to the fact that oil is a viscous organic pollutant, the changes of 0.25, 0.5, 1, 3, 5, 7, 10 mm microaggregates, which are important for soil fertility, as a result of pollution, and changes in the amount of these microaggregates were also determined. It was found that the soils around the South Mirshodi oil field were previously contaminated and the amount of microaggregates smaller than 0.25 mm, 0.25 mm, 1 mm, 2 mm and 3 mm in the irrigated soils increased as the distance from the source of contamination increased. This is explained by the decrease in the concentration of oil in the soil. The amount of 5 mm, 7 mm and 10 mm aggregates has decreased. A similar situation was observed around the Kumkurgan oil base.
