In recent years the question about organic cultivation of crops is becoming more popular. It means, that farmers which want to use organic products and grow crops it sustainable way have to follow certain rules. So, the aim of our study was to estimate effect of seed inoculation and foliar fertilization of corn by special fertilizer products with microorganisms that certified Organic standard. Therefore, corn seeds were treated by biofertilizers in liquid (Leanum) and powdered (Vitamin O7) forms and then sown in the field conditions. During summer period, plants were treated by liquid fertilizer one or two times. Also, impact of the soil tillage was studied. Research was conducted on the effects of cultivation at depths of 15-18 and 5-8 cm, as well as plowing and flat-cutting cultivation at depths of 25-28 cm. It was found that fertilization impacted on corn yield and grain quality - protein, ash and starch content. Usage of seed inoculants and foliar fertilization in generally leads to increase yield but at different levels. Protein and oil content had a weak positive correlation with applied fertilizers on the background of flat-cut tillage. [ABSTRACT FROM AUTHOR]

Objectives: The study aimed to investigate heavy metal contamination (copper, arsenic, manganese) in Georgian rivers affected by mining and develop a two-stage water purification technology using Spirulina (Arthrospira platensis) and trehalose lipid (TRL).

The purification process involved a 72-h incubation in a primary tank, followed by membrane filtration and the addition of biomass with trehalose lipid (TRL) in a secondary tank. Post-treatment data revealed significant reductions in manganese and copper concentrations, bringing them below permissible thresholds. These data highlight the effectiveness of the two-stage purification technology in removing heavy metal contaminants from water sources impacted by industrial pollution. The findings demonstrate the potential of this technology to improve sustainable water management practices and provide scalable solutions for communities facing similar water quality challenges. Article Highlights: Two-stage purification with Spirulina reduced heavy metals in water from mining-affected rivers. Manganese and copper levels dropped below safety thresholds after treatment. The technology shows promise for improving water quality and public health. [ABSTRACT FROM AUTHOR]

The article is devoted to identifying the podcast activity of Ukrainian publishers as an important innovation component of their marketing activities. The objective of the article is to study the level of podcast activity of Ukrainian publishing houses and to analyze the thematic diversity of domestic publishing podcasts as an aspect of the innovative component of the publishing business. The 130 Ukrainian publishing houses were analyzed to determine their podcasting activity by formal and content features. It has been found that only 8 publishers create their own podcasts (mostly 1-2 podcasts from the publishing house; a total of 14 podcasts, 163 episodes). The methodological basis of the study is content analysis, methods of generalization, comparison, analysis, and synthesis. The study found that publishers are the most active: Laboratory (podcasts such as "Laboratory of Senses" that includes 22 episodes; "Laboratory of Nonfiction" - 26 episodes); Astrolabe (podcast of Radio "Astrolabe" with 32 episodes); Dukh i Litera (podcast "Laboratory: 1000" including 4 episodes; "Dukh i Litera: Podcast" - 20 episodes). The overwhelming majority of the analyzed episodes in all podcasts (58%) by category are devoted to discussing books published by publishing houses, in particular in the form of conversations with translators, publicists, and editors; 27% of them are episodes that do not deal with book publishing. Literary and literary-related topics are devoted to 8% of podcasts; authors' creative paths, genres, etc. are covered in 7% of podcasts. [ABSTRACT FROM AUTHOR]

The article is devoted to considering podcast advertising as a means of monetizing. The podcast advertising types are characterized. An analysis of the domestic experience of using podcasts for advertising purposes was carried out. The purpose of the article is to consider the main types of podcast advertising and analyse their use in the Ukrainian segment of the media market. Podcasts of Radio NV, Suspilny, "The Ukrainians", "Ukrainian Pravda" have been analysed. Content analysis of podcasts was chosen as the main research method to identify the types of advertising used in domestic podcasts. The main characteristics of the classification of podcast advertisements and the types that are distinguished within these characteristics have been established. It was found that Ukrainian podcasts most often use self-promotion, but there are isolated cases of partnership and sponsorship (usually at the end of the podcast) and mentions that can be identified as native advertising. It was concluded that it is too early to talk about the monetization of podcasts thanks to advertising as a mass phenomenon, it is rather an exception to the rule than a regularity. An effective way of interacting with the audience is thematic projects and those ones, which are designed for a specific brand, which is their sponsors. [ABSTRACT FROM AUTHOR]

The results of research on the influence of plant standing density and level of mineral fertilization on growth and development of sweet corn plants of hybrid Moreland F1 on sod-podzolic soils have been presented. The change in influence degree of technological factors on the height of sweet corn plants in different periods of the crop growth and development has been established. It was determined that the longest vegetation period had the crops of sweet corn grown under conditions of full mineral fertilization and maximum plant density of 80.000/ha - 80.3 days, and the shortest one was on the variant with unfertilized background and plant density of 60.000/ha - 73.2 days. Increase of mineral fertilizer dose contributed to better growth of sweet corn than in variants without mineral fertilizers. Increase of plant density up to 80.000/ha led to unnatural stretching of plants (over 190 cm). It was determined that the optimal plant height of the crops was at the density of 60 thousand/ha on the background of nutrition N135P90K125 + N60 + N30. The maximum average daily growth was characterized by sweet corn plants on the background of nutrition N135P90K125 + N60 + N30 with plant density 80.000/ha - 2.93 cm. [ABSTRACT FROM AUTHOR]

The article describes the features of acquiring artistic and creative competence, as a child's elementary awareness of the specifics of art forms (artistic and productive, musical, theatrical); valuable attitude to art and artistic activity, the desire to perceive folklore art. Folkloric forms of the heritage of Ukrainian culture are considered. Teaching and methodical material and practical recommendations are offered, which in music classes will be useful both to experienced teachers of preschool institutions and to those workers who are starting to work with the smallest brains. Normative documents in the field of preschool education were studied and play competence was considered as a child's ability to free, emotionally saturated, spontaneous activity on his/her own initiative, in which the possibility of applying existing and assimilating new knowledge and personal development is realized due to the child's desire to participate in the life of adults through the realization of interests in game and role-playing actions in a generalized form. The necessity of using folk games for the formation of artistic and creative competence in preschool children is substantiated. Peculiarities of knowledge of the surrounding world of preschool children and themselves in it are determined. The work proposes to create a basis for the natural formation and development of musical abilities in preschoolers through a folk game by encouraging children to play folk games. It has been emphasized that raising children is based on love and respect for Ukrainian musical folklore. The secrets of conducting music classes using folk games and working with preschoolers are recommended to teachers of primary schools, music teachers, teachers of children's vocal ensembles of extracurricular and club institutions, scientists, graduate students, students of pedagogical and art educational institutions, parents and the general public [ABSTRACT FROM AUTHOR]

The influence of mineral fertilizers on productivity and nutrient balance of sod-podzolic soil when growing cereal meadow agrophytocenosis under conditions of Precarpathians of Ukraine was researched. It was found that the dependence of cereal agrocenosis productivity on the doses and ratios of N, P, K in mineral fertilizers is described by equation (polynomial) of the 2nd degree. Among the mineral elements, nitrogen is has the greatest influence on grass productivity. When applying the total dose of N75 with even distribution of nitrogen under each of three mowings on different backgrounds of phosphorus-potassium fertilizers, the productivity of cereal grass increases by 2.82-3.06 t ha-1 of dry mass, and when applying N150 by 3.33-4.93 t ha-1 of dry mass. Recoupment of nitrogen fertilizers per 1 kg by yield increase when applying N75 is 38-41 kg of dry mass, which is 4-5 kg more compared to the application of N150. The indices of phosphorus and especially potassium removal, as well as deficiency of these elements in the balance increased along with nitrogen dose. Independently of the phosphorus and potassium doses, the lowest indices are fixed on a nitrogen-free background, and the highest - on the background of N150. [ABSTRACT FROM AUTHOR]

Productivity and mowing periods of various cereal grasses on sod-podzolic soil of Pre-Carpathians were studied. The presence of sown grasses with different ripeness periods provides uniform supply of mowing mass from the middle of May till late September and productivity of lands, which is 5.4-6.8 t ha-1 of dry mass, exchange energy - 44.1-56.8 GJ ha-1 and 3.81-4.87 t ha-1 f.u. On the basis of the obtained results, it was found that with increase of tillage depth from 8-10 cm for surface tillage with disk tools to 20-22 cm by plowing, the productivity of all studied species increased by 2-3% on average for three years with fertilization dose of LSD05 equal to 0.30 t ha-1. Cultivation of cereal grasses on sod-podzolic soils stipulates improvement of their fertility, in particular increasing indices of nitrogen, phosphorus and potassium. [ABSTRACT FROM AUTHOR]

The influence of biosurfactants of trehalose lipid nature (R. erythropolis Au-1) and rhamnolipid nature ( Pseudomonas sp. PS-17) on the efficiency of the absorption of K+ and Ca2+ ions and plants growth was studied. The seeds of soybean, wheat and sunflower after the presowing treatment by the biosurfactants solutions were grown on a liquid nutrient medium. The residual contents of K+ and Ca2+ ions in the medium were different for the variants with the biosurfactants and control (water). Based on these parameters, it was possible to value the stimulating effect of the biosurfactants on the plants’ ability to absorb mineral elements from the nutrient medium. The plants after the pre-treatment by the biosurfactants absorbed on 10-40% (trehalose lipids) and 27-61% (rhamnolipid biosurfactants) K+ and Ca2+ ions more than control variants. The growth parameters of plants were increased on 17-24% (trehalose lipids) or 39-77% (rhamnolipid biosurfactants). The experiments with plants (wheat, soya and sunflower) were also conducted in field conditions. The results showed that the trehalose lipid and rhamnolipid biosurfactants provide an increase in crop yields on 19-23% as well as the yield quality. The obtained data allowed to suggest a possible mechanism for the influence of surfactants on the plant growth. [ABSTRACT FROM AUTHOR]

Cardiovascular diseases (CVDs) are the leading cause of premature deaths globally and in Ukraine. Dyslipidemia is a recognized risk factor for the development of CVD. Therefore, early detection and appropriate management of dyslipidemia are essential for the primary prevention of CVDs. However, currently, there is a lack of Ukraine-specific guideline recommendations focusing on the management of dyslipidemia in individuals with low-to-moderate CV risk, thus creating an urgent need for structured and easily implementable clinical recommendations/guidelines specific to the country. An expert panel of cardiologists, endocrinologists, and family physicians convened in Ukraine in March 2019. The expert panel critically reviewed and analyzed the current literature and put forth the following recommendations for the management of dyslipidemia in individuals with low-to-moderate risk of CVDs specific to Ukraine: (1) family physicians have the greatest opportunities in carrying out primary prevention; (2) lipid-lowering interventions are essential for primary prevention as per guidelines; (3) a number of nutraceuticals and nutraceutical combinations with clinically established lipid-lowering properties can be considered for primary prevention; they also have a suggested role as an alternative therapy for statin-intolerant patients; (4) on the basis of clinical evidence, nutraceuticals are suggested by guidelines for primary prevention; (5) red yeast rice has potent CV-risk-lowering potential, in addition to lipid-lowering properties; (6) in patients with low-to-moderate cardiovascular risk, a nutraceutical combination of low-dose red yeast rice and synergic lipid-lowering compounds can be used as integral part of guideline-recommended lifestyle interventions for effective primary prevention strategy; (7) nutraceutical combination can be used in patients aged 18 to 75+ years; its use is particularly appropriate in the age group of 18-44 years; (8) it is necessary to attract the media (websites, etc.) to increase patient awareness on the importance of primary prevention; and (9) it is necessary to legally separate nutraceuticals from dietary supplements. These consensus recommendations will help physicians in Ukraine effectively manage dyslipidemia in individuals with low-to-moderate CV risk. [ABSTRACT FROM AUTHOR]

This study presents an in-depth investigation of the critical stretch based failure criterion in ordinary state-based peridynamics for both static and dynamic conditions. Seven different cases are investigated to determine the effect of the failure parameter on peridynamic forces between material points and dilatation. Based on crack opening displacement (COD) results from both peridynamics and finite element analysis, it was found that one of the seven cases provides the best agreement between the two approaches. This particular case is further investigated by considering the influence of the discretisation and the horizon sizes on COD and crack propagation speeds. Moreover, PD predictions of COD for PMMA material is analysed with the theory of dynamic fracture mechanics and compared with the fracture experiments. It is shown that the peridynamic model can correctly model, simulate and predict the behaviour of the crack under different loading conditions. Furthermore, the presented PD models capture accurate fracture phenomena, specifically the crack path, branching angles and crack propagation speeds, which are in good agreement with experimental results.

The electrochemical method of synthesis of silver nanoparticles (AgNPs) using 'sacrificial' silver anode as a source of Ag+, microbial origin surfactant (rhamnolipid, RL) as a stabiliser of AgNPs and electric current as a reducer is presented. Using of cyclic voltammetry it was determined that RL concentration and temperature are the main factors influencing the rate of anodic dissolution of silver and cathodic reduction of the formed complex [AgRL]+. Increasing of RL concentration leads to increasing of the cathodic currents that indicate the increase of the rate of AgNPs formation. With increasing the temperature from 40 to 60°C the values of the anode and cathodic currents increase to 1.5 times, this indicates the predominant diffusion nature of the influence of the temperature on the synthesis of AgNPs. Obtained AgNPs were investigated using transmission electron microscopy and it was found that increasing of concentration of surfactant leads to decreasing of the size of AgNPs, whereas increasing of temperature, on the contrary, leads to increasing of mean size of AgNPs. Synthesised AgNPs showed significant antimicrobial activity against the bacterial phytopathogens Xanthomonas campestris and Agrobacterium tumefaciens. It has been shown that AgNPs stabilised by RL are characterised by low phytotoxicity. [ABSTRACT FROM AUTHOR]

Purpose The purpose of this paper is to study the influence of rhamnolipid biosurfactant complex on the corrosion and the repassivation of a freshly cut Al-Cu-Mg aluminium alloy surface.Design/methodology/approach The electrochemical methods, supported by quantum-chemical calculations and scanning electron microscopy data, were used.Findings It was established that the rhamnolipid biosurfactant effectively inhibits corrosion of the alloy in synthetic acid rainwater. The efficiency of inhibition becomes stronger with the increase of biosurfactant concentration; however, above the critical micelle concentration, the further improvement in inhibition is minor. It is believed that the mechanism of corrosion inhibition is related to the adsorption of the biosurfactant molecule on the aluminium alloy surface and the formation of a barrier film; however, the formation of a complex compound (salt film) between aluminium ions and rhamnolipid on anodic sites of the alloy is not ruled out. In case of surface mechanical activation of the alloy, the biosurfactant molecule effectively prevents corrosion. Furthermore, addition of the biosurfactant to the corrosion environment increases the repassivation kinetics of the alloy by two to four times as compared with an uninhibited environment.Practical implications The commercial impact of the study consists in the possibility of obtaining of environmentally safe corrosion inhibitors of aluminium alloys by biosynthesis from renewable agricultural raw materials.Originality/value The originality of this paper is to study the effectiveness of “green” corrosion inhibitor based on biogenic product on freshly generated surface of aluminium alloy.

Introduction. Due to the fact that the production of microbial surfactants is limited by the low yield of end products and high cost of processes, the actual task is to optimize and reduce the cost of the technology of biosurfactants synthesis. One of the solutions of this problem is to use the industrial wastes, including rape phosphatide concentrate (PC). Materials and methods. Hexadecane and rape phosphatide concentrate (2%) were used as a carbon source in a nutrient medium for the cultivation of bacteria. Lipids were extracted from a cell mass and supernatant by the mixture of chloroform-methanol 2:1. The qualitative analysis of metabolites was performed by a thin layer chromatography. Results and discussion. The peculiarities of synthesis of biosurfactants by strains G. rubripertincta UCM Ac- 122 and R. erythropolis Au-1 during the growth on the nutrient media with rape phosphatide concentrate as a carbon source was studied. Quantity of biomass was 9.4 - 10.1 g/l, exopolymers - 8.9-9.5 g/l and the content of cellbound trehalose lipids was 1.37 - 2.26 g/l; whereas the content of exogenous trehalose lipids - metabolites of R. erythropolis Au-1 was 2.95 g/l. It was found that the addition of trehalose lipids (0.01 g/l) to the nutrient medium caused the increase of biomass on 14.6 - 17.0% and cell-bound lipids on 13.9 - 15.5%. Conclusions. Rape phosphatide concentrate is economically viable carbon source in the technologies of surfactant production by Actinobacteria. Its use promotes an increasing of exogenous surfactants strain R. erythropolis Au-1 in 3-fold compared with cultivation on nutrient medium with hexadecane. Trehalose lipids show a stimulating effect on growth and synthesis of biosurfactants by strains of G. rubripertincta UCM Ac-122 and R. erythropolis Au-1. [ABSTRACT FROM AUTHOR]
