Published: March 2024

In the last decade, the use of integrated reports (IR) comprising information on non-financial indicators from the environment, social, and governance (ESG) category has increased in time. Companies are now focusing not only on financial reporting but are notably including non-financial issues in their public reports. In doing so, they seek to align activities with the expectations of their stakeholders and the society in which they operate, as well as with various regulations, which are increasingly relevant worldwide. This study examines the impact of ESG reporting on company performance. Our research involved analyzing financial and non-financial data from 2,400 companies extracted from the Refinitiv Eikon database. Two methods of quantitative analysis were applied, namely multiple linear regression models processed by the robust regression method and structural equation modelling. Main findings entail that ESG indicators had strong and medium effects on company performance, but these effects varied across different dimensions, requiring a tailored approach to embed ESG factors in corporate strategy to enhance overall performance. Our paper provides a new perspective on the current and the potential impact of ESG reporting, based on systematic theoretical and empirical analyse , with multiple implications for business administration and management.
DuPont analysis among European dentistry companies to measure the impact of the COVID-19 pandemic
Authors: Heryan Tomas , Gajdova Karin
Published: March 2024

Although health economics belongs to the highly respected economic disciplines within the research literature, there is a considerable gap related to the investigation of dentistry in particular, even after the global pandemic of COVID-19 disease. Fundamentally, the DuPont framework is a well-known complex analysis to evaluate companies from the point of view of financial performance. The investigation of the return on equity as a relation between the return on assets and the equity multiplier, simply called the leverage effect, is presented in this paper. Therefore, this study aims to estimate the effect of leverage and its changes due to the COVID-19 pandemic among dentistry companies in selected European countries with different healthcare insurance systems. This comparative investigation focused on the generalised method of moments with dynamic panel data from Orbis, the Bureau van Dijk financial database for 1,128 dentistry companies in nine European countries. Methodologically, concerning those post-estimation techniques to evaluate over- and underestimation of the models. It has been differentiating between companies with a high or low ownership concentration structure. The results have shown differences in the leverage effect during the pandemic, assuming that companies with a major owner increased their equity, while the debt leverage increased among those companies with dispersed ownership and vice versa. If economic theory states that debt financing is more effective for a company than using internal sources, it is apparently different in the case of dentistry during the pandemic. However, dispersed ownership is more often related to dentistry, according to mergers in this particular business industry.

This study aims to analyze the contributions of the pedagogical companion to the teaching practices of educators in rural schools in the Bío Bío region. Methodology. The study employs a qualitative approach and a collective case study design. Semi-structured interviews and documentary analysis were conducted with 19 General Basic Education teachers, aged between 22 and 65 years. Results. The main results reveal that the pedagogical companion plays a guiding role in collaboratively designing lesson plans. In addition, systematic and timely feedback, both oral and written, strengthens the higher-order thinking skills of the teachers being accompanied. Furthermore, pedagogical accompaniment fosters the innovation of teaching practices through peer collaboration, based on dialogue and reflection. Indeed, reflective practice is of vital importance in the training of teachers with critical thinking skills, thus benefiting professional development, which is reflected in the reformulation of teaching practice, oriented towards situated teaching and learning. The systematic pedagogical accompaniment develops the capacity for pedagogical leadership in the accompanied teachers. Conclusions. Pedagogical accompaniment is a key process in improving teaching practices and strengthening the professional performance of the teachers being tutored. This has a significant impact on student training and the generation of social transformations in rural education and in other educational contexts. In this sense, continuous self-improvement is recommended for teachers to meet the demands of contemporary society.
Polyamidoamine epichlorohydrin (PAAE) wet-strength agent: Generations, application, performance, and recyclability in paperboard and linerboard
Authors: Ntifafa Yao , Ji Yun , Hart Peter W.
Published: March 2024

Polyamidoamine epichlorohydrin (PAAE) is the preeminent permanent wet strength additive used in papermaking. Wet strength additives are used to improve paper resistance to a rupture force in wet environments. The invention of PAAE in 1957 was an innovation, as it improved paper properties by giving superior wet strength in humid or wet conditions. It was rapidly adopted by the industry. Despite PAAE’s long history, the mechanism of PAAE interaction with fiber has not been fully understood. Therefore, fundamental understanding of PAAE mechanism needs to be investigated to improve its utilization in making sustainable paper products. These areas include an understanding of repulping methods and optimal PAAE dosages for better cost and performance. This paper investigates different generations of PAAE, the application method, and its impact on paper recyclability. Three generations of PAAE are currently on the market with at least two newer iterations under development. Critical application parameters that need to be understood include determination of the bonding mechanism, optimal dosage, and retention parameters. The main drawback of PAAE application is it makes paper recycling difficult. Several repulping methods are proposed for better recyclability and sustainability in the papermaking process.
Genetic Selection of Trees with Designer Fibres for Different Paper and Pulp Grades

Published: March 2024

Pinus radiata and eucalypts are fast-grown species, well suited to plantation forestry in New Zealand and elsewhere, and for the manufacture of a wide range of solid wood and reconstituted wood products, including pulp and paper. This paper examines the variation and end-use potential of the individual-tree kraft fibre and handsheet properties of 25 trees of 13-year-old P. radiata and 29 trees of 15-year-old Eucalyptus nitens. Individual-tree fibre property differences are assessed with reference to the fibre quality requirements of a range of wood-free paper grades. Strategies and procedures are also described which will enable parent trees with desired fibre properties to be identified, propagated and mass produced. In selecting fibre types for different paper and pulp grades, the apparent density of “unrefined” pulps(500 PFI mill rev) is the base against which other “unrefined” handsheet properties are compared. Apparent density is a direct measure of fibre packing density and arrangements in handsheets, and is determined by fibre length and cross-section dimensions, and the related morphological configurations of collapse and straightness. Although the individual-tree pulps of both species can normally be refined to the same tensile index, apparent density values can be very different depending on their fibre properties. Thus, minimal pulp refining is preferred for comparing individual-tree pulps for trees election. Apparent density is best predicted by the kraft fibre property combination of the fibre width/thickness ratio and length. The combination of chip basic density and kraft fibre length is also a good predictor of handsheet apparent density but not necessarily of the best fibres for the manufacture of particular products. Wood density is a measure of the ratio of wood substances to void space in each individual-tree chip sample and is not indicative of the numbers of fibers which make up a unit volume. Kraft handsheet properties varied widely among trees for both species and were well-predicted by kraft-fibre dimensions. The high broad-sense heritabilities shown for these traits in P. radiata mean that clonal forestry could provide pulpwood of uniform and predictable pulping performance from monoclonal forest blocks. The high narrow-sense heritabilities shown so far for wood properties in P. rafiata (and for some wood properties in E. nitens) indicate that planting control-pollinated families of known characteristics could have a similar though less uniform result.
Bausmių bendrinimo ypatumai ir galutinės bausmės teisingumas Lietuvos teismų praktikoje
Authors: Pranka Darius
Published: March 2024

Scholars of criminal law have not considered the issue of consolidation of criminal penalties for some time, and it has been undeservedly forgotten. However, the method of consolidation of criminal penalties and the size of the final punishment are very important for the defendant. In addition, in judicial practice, there are often various problems related to the correct and appropriate summation of sentences. It is sometimes very easy to get lost in the labyrinths of sentence sizes, numbers and calculation of the last sentence. The article begins by presenting a negative example of judicial practice, when the lower court, ignoring the decision of the appeal court, decides to postpone the execution of the prison sentence after the sentence has been combined. Next, the author raises the question of why criminal law provides only the minimum amount of penalties to be added. Still, when putting together several sentences, adding at least the minimum part of the penalties is not mandatory. On the other hand, in the context of this problem, we can reasonably doubt whether, in cases where the offender commits several dozen or several hundred criminal acts, putting together the punishments and adding a minimum part of each punishment, the last punishment is not too severe. Finally, at the end of the article, the difficulties of putting together punishments are shown when punishments have to be shared by simultaneous application of Article 63 of the Criminal Code and Article 64 of the Criminal Code.
When people still had enough time to live
Authors: Rébay Magdolna
Published: March 2024

In this paper the author want to focus especially on the education of girls from Hungarian aristocratic families by studying not only the relationship between the parents and the children but also the aim, content, methods of education. The sources were primarily the memoirs that have been more frequently published, that resulted in more detailed, subtle conclusions complete with personal motivations as well. The research method was narrative text analysis. The author concluded that there were practically only some aristocratic girls who had enrolled a secondary school before WW1. After WW1 there were more and more girls taking part in school education, the reason being their financial circumstances and the changed social and cultural situation. Some have already enrolled in university or obtained a vocational qualification. However, working women were very rare among them. The relationship between the parents and children was different by families, but the strict distance increasingly loosened up. One of the most important goal of education was the knowledge of modern languages. Besides practising religion and arts physical education and sports were present in the lives of the girls in the country. Girls could only move around in their own social groups, they put special emphasis on developing social competences. A girl's goal was to find a spouse who is worthy of her rank.

The clinical role of Acinetobacter baumannii has been highlighted in numerous infectious syndromes with a high mortality rate, due to the high prevalence of multidrug-resistant (MDR) isolates. The treatment and eradication of this pathogen is hindered by biofilm-formation, providing protection from noxious environmental factors and antimicrobials. The aim of this study was to assess the antibiotic susceptibility, antiseptic susceptibility and biofilm-forming capacity using phenotypic methods in environmental A. baumannii isolates. One hundred and fourteen (n = 114) isolates were collected, originating from various environmental sources and geographical regions. Antimicrobial susceptibility testing was carried out using the disk diffusion method, while antiseptic susceptibility was performed using the agar dilution method. Determination of biofilm-forming capacity was carried out using a microtiter-plate based method. Resistance in environmental A. baumannii isolates were highest for ciprofloxacin (64.03%, n = 73), levofloxacin (62.18%, n = 71) and trimethoprim-sulfamethoxazole (61.40%, n = 70), while lowest for colistin (1.75%, n = 2). Efflux pump overexpression was seen in 48.25% of isolates (n = 55), 49.12% (n = 56) were classified as MDR. 6.14% (n = 7), 9.65% (n = 11), 24.65% (n = 28) and 59.65% (n = 68) of isolates were non-biofilm producers, weak, medium, and strong biofilm producers, respectively. No significant differences were observed between non-MDR vs. MDR isolates regarding their distribution of biofilm-producers (P = 0.655). The MIC ranges for the tested antiseptics were as follows: benzalkonium chloride 16–128 μg mL−1, chlorhexidine digluconate 4–128 μg mL−1, formaldehyde 64–256 μg mL−1 and triclosan 2–16 μg mL−1, respectively. The conscientious use of antiseptics, together with periodic surveillance, is essential to curb the spread of these bacteria, and to maintain current infection prevention capabilities.
An examination of internal family systems interventions for trauma with implications for ethical psychedelic-assisted treatment
Authors: Earleywine Mitch , Oliva Alyssa B. , De Leo Joseph A. , Banks Robyn
Published: March 2024

Though several treatments effectively address the pervasive impact of trauma, they do not achieve complete symptom resolution for all clients, inspiring the search for alternatives. Internal Family Systems (IFS) therapy has grown popular, especially in informal psychedelic-assisted treatments (PAT). Compared to stereotypes of empirically validated, exposure-based treatments, IFS has novel facets with widespread appeal. The model encourages improved quality of interactions among multiple, naturally arising “parts” or subpersonalities potentially generated by traumatic experience. The body of IFS literature is extensive, enthusiastic, and thought-provoking. Outcome data for applying the model to Post-Traumatic Stress Disorder are limited. Attempts to operationalize and falsify the theory's assumptions and proposed mechanisms will likely prove challenging. Nevertheless, the model's popularity underscores a problem with perceptions of the empirically-supported treatments. Contemplating ethical ways to present the IFS approach given the state of relevant research, we note strategies that would apply to recommendations for PAT of any type. These strategies include detailed psychoeducation about empirically-supported treatments, candid description of the experimental nature of alternatives, frequent assessments of improvement, and detailed monitoring of potential iatrogenic effects. Drawing on facets of IFS to improve perceptions of the empirically validated treatments might provide an efficient way to appeal to more clients, decrease drop out, and increase gains as we await results of empirical investigations of IFS-influenced PAT. These steps can allow clients to choose an approach consistent with their own impressions of a credible intervention, potentially leading to better outcomes.

Published: March 2024

Agguttinni Territorial Park is a large, newly established park on the east-central coast of Baffin Island in Nunavut, Canada. Previous knowledge of the plant and lichen biodiversity was limited and based mostly on collections made during the 1950 Baffin Island Expedition. We conducted a ﬂoristic inventory of the park in 2021 and re-examined previous collections. We recorded 141 species of vascular plants belonging to 25 families, 69 species of bryophytes in 27 families, and 93 species of lichens in 23 families. Most of the vascular plant and bryophyte species are new records for the park area, and some vascular plants, bryophytes, and lichens are newly reported for Baffin Island, Nunavut, or the Canadian Arctic or represent signiﬁcant range extensions. Vascular plant species diversity varied greatly among localities, with inland valleys at the heads of ﬁords showing highest diversity and interior rocky barrens showing the lowest.
Arab Origins of Tavukgögsü and Blancmange
Authors: Topçu Utku Can
Published: March 2024

The origins of the European blancmange and the Turkish tavukgögsü (chicken-breast (white) pudding) have been the subject of academic and culinary interest for many years. Usually, both have been traced back to Roman sources: John Ayto, author of The Diner’s Dictionary, repeats a claim that blancmange originates from De re coquinaria; while Tugrul Savkay, a Turkish gourmet and author of books about the history of Turkish cuisine, suggests the same is true of tavukgögsü. De re coquinaria, also known as Apicius, allegedly included a recipe that resembles both dishes; however, it failed to survive in modern copies of the book. This article argues that the antecedents of both blancmange and tavukgögsü are actually harisa recipes that are cooked in the Arab world to this day.

Published: March 2024

The results reported here proved the necessity of introducing financial controlling tools into the system of adaptive management of the company's financial security, which is inextricably linked with technology transfer. The object of the study is the movement of technology with the application of any information on ensuring the implementation of financial controlling tools in the process of managing the financial security of enterprises. We analyzed theoretical approaches to adaptive management of financial security of enterprises. The principles, functions, and types of financial controlling were considered. The expediency of researching the financial security of enterprises using financial controlling as a functional system of adaptive management of deviations has been proven. A systematic approach was used to study scientific approaches to adaptive management of financial security based on financial controlling. Considerable attention was paid to the analysis of the functions and tasks of financial controlling under today's unstable conditions of the economic development of enterprises. Using the method of system analysis, theoretical and methodological approaches to understanding the essence of financial controlling in the adaptive management of financial security of enterprises were evaluated. Peculiarities in the scientific approaches of various scientists regarding the essence of the financial security of enterprises have been revealed. The role and significance of adaptive management of the financial security of enterprises with the help of a modern toolkit of financial controlling, which consists of contractual obligations that make it possible to ensure an effective mechanism for making managerial decisions regarding the enterprise and its counterparties or other financial institutions, is revealed. The extended capabilities of the financial controlling toolkit are useful for analysts and enterprise managers to justify and improve the quality of adaptive management of the enterprise's financial security in modern conditions of technology transfer
Determining the effect of a floating point on the Falcon digital signature algorithm security
Authors: Potii Oleksandr , Kachko Olena , Kandii Serhii , Kaptol Yevhenii
Published: March 2024

The object of research is digital signatures. The Falcon digital signature scheme is one of the finalists in the NIST post-quantum cryptography competition. Its distinctive feature is the use of floating-point arithmetic. However, floating-point arithmetic has so-called rounding noise, which accumulates during computations and in some cases may lead to significant changes in the processed values. The work considers the problem of using rounding noise to build attacks on implementation. The main result of the study is a novel attack on implementation, which enables the secret key recovery. This attack differs from existing attacks in using two separately secure implementations with different computation orders. As a result of the analysis, the conditions under which secret key recovery is possible were revealed. The attack requires 300,000 signatures and two implementations to recover key. The probability of successful attack ranges from 70 % to 76 %. This probability is explained by the structure of the Gaussian sampling algorithm used in the Falcon digital signature. At the same time, a necessary condition for conducting an attack is identical seed during signature generation. This condition makes the attack more theoretical than practical since the correct implementation of the Falcon makes probability of two identical seeds negligible. However, the possible usage of floating-point noise shows potential existence of additional attack vectors for the Falcon that should be covered in security models. The results could be used in the construction of digital signature security models and their implementation in existing information and communication systems
Determining the influence of sandwich-type components on the load of a hatch cover in a universal open wagon

Published: March 2024

The object of the study reported here is the processes of occurrence, perception, and redistribution of loads in the improved structure of the hatch cover in a universal open wagon.
In order to reduce the load on the cover of an open wagon hatch, and, accordingly, to improve its strength, it is proposed to improve its design by introducing sandwich components. The thickness of the sheets that form the hatch cover has been determined. The dynamic loading of the hatch cover in the vertical plane was studied. It was found that the accelerations acting on the hatch cover with the proposed improvement are almost 20 % lower than those acting on the typical structure. The basic strength indicators of the hatch cover under the operational modes of its load have been determined. The results of the calculation showed that the maximum stresses in the hatch cover are 22 % lower than permissible ones. In addition, within the framework of the study, the main indicators of the dynamics of the open wagon equipped with the proposed structure of hatch covers were determined. The movement of the open wagon under the condition of movement in an empty state is rated as "good". At the same time, the maximum accelerations in the center of mass of the supporting structure of an open wagon were 4.6 m/s2, and the coefficient of vertical dynamics was about 0.6.
Special features of the results within the framework of this study are that the proposed improvement of the hatch cover helps improve its strength by reducing the dynamic load, and not by strengthening the structure.
The scope of practical application of the results is the engineering industry, in particular, railroad transport. The conditions for the practical use of the research results are the use of energy-absorbing material in the sandwich-type components that form the hatch cover.
The study reported here could contribute to devising recommendations for the construction of components in the structures of modern freight cars, thereby reducing the costs of maintaining them in operation, as well as increasing the profitability of railroad transportation

Published: March 2024

The object of research is the process that forms strategies and methods for effective commercialization of intellectual products at industrial enterprises. The problems of introducing intellectual property objects into the economic circulation in the field of industrial production have been analyzed. The most important of them are economic and managerial problems, which consist in the lack of necessary funding and are determined by the difficulty of assessing the market competitiveness of an intellectual product. Special attention was paid to market, technical-technological, and legal problems, the presence of which inhibits the development of the technological market and significantly affects the efficiency of intellectual and innovative activities. The presence of these problems predetermined the main goal of the study – to devise methods and strategies for the commercialization of intellectual property objects.
Three basic strategies for the commercialization of intellectual products have been studied: the strategy of promoting an intellectual product, the strategy of diffusion of innovations, and the strategy of accumulating maximum income. Based on them, an integrated strategy for the commercialization of intelligent products for enterprises of the machine-building industry, which is oriented towards achieving the goals of maximizing the economic and social effect of the production of an intelligent product, was formed and substantiated. The main component of an integrated strategy is an organizational mechanism that provides investment support for innovative activities and scientific and consulting support for an intellectual product.
The research results could be used to form programs of intellectual and innovative activity of industrial enterprises and would serve as a basis for further scientific research on these issues
Enhancing the quality and technological properties of goose meat during low-temperature storage through the action of biologically active substances from oats and alfalfa
Authors: Maiboroda Daniil , Danchenko Olena , Gryshchenko Viktoriya , Danchenko Mykola
Published: March 2024

Poultry meat plays a key role as a source of high-quality protein, vitamins, minerals, and unsaturated fatty acids. However, unsaturated fatty acids, especially essential ones, are prone to oxidative reactions during meat storage, which can negatively affect its quality. The object of the study is the technology of obtaining and storing poultry meat. Legart Danish geese were used as the experimental material. Oats (Avena Sativa) and alfalfa (Medicago sativa) contain a large number of biologically active substances (minerals, unsaturated fatty acids, amino acids, antioxidants). Adding vegetative parts of oats and alfalfa to the diet of geese contributes to improving the quality of the obtained meat, especially after prolonged low-temperature storage. The geese were slaughtered on the 63rd day. The meat was stored at a temperature of –18 °C for 90 days.
It was found that there was an 11.5 % increase in the live weight of the geese at an early slaughter age, an increase in protein content (by 5 %), better moisture-binding capacity (by 6–7.3 %), and a decrease in the content of lipid peroxidation products, especially on the 67th day of storage (28.3 %). There was a significant increase in the content of ω3 and ω6 polyunsaturated fatty acids (by 24.2 % and 10.8 %, respectively). There was an increase in the content of vitamin E and β-carotene, both before freezing (38.5 % and 19.6 %) and at the end of the storage period (50.9 % and 20 %). A tendency to increase the content of essential amino acids (threonine and methionine) was found. The results can be used in the production of goose meat to improve its nutritional characteristics, which is important for the health of consumers, meat producers, and also in scientific research on the development of technologies in the field of meat production and storage
Designing energy-efficient hardware and technological structure of absorption refrigeration units for ammonia production

Published: March 2024

The object of research is the equipment and technological design of absorption refrigeration units (ARUs) for the technological system of secondary condensation of large-scale ammonia production. Improving the energy efficiency of ARU is an urgent problem in the general process of reducing operating costs for natural gas in these industries as a whole.
Based on the results of analytical studies, the feasibility of combining absorption-refrigeration and vapor-ejector cycles was substantiated, which ensures a decrease in the boiling temperature of a weak water-ammonia solution in the cube of the generator-rectifier and an increase in the condensation pressure in the ARU cycle. Under such circumstances, it becomes possible to increase the concentration of the refrigerant due to the rectification of steam with a part of the liquid refrigerant without using a pump with the removal of the dephlegmator from the ARU circuit.
Experimental studies and material-thermal calculations of ARU cycles were carried out to determine the basis of comparison and the proposed version of the ARU scheme. It has been proven that the new technological design of ARU provides an increase in cooling capacity from 3.22 MW to 3.6 MW (by 12 %), the thermal coefficient from 0.527 to 0.551 (by 4.6 %), a decrease in the circulation ratio from 7.77 to 7.1 (by 8 %), and a decrease in the secondary condensation temperature by 2.5 ℃.
It is shown that for the proposed version of the technological design of ARU, there is a change in specific costs – an increase in electricity by 1.48 kWh/t NH3 and a decrease in natural gas by 0.41 nm3/t NH3. Taking into account existing cost indicators for natural gas and electricity, the application of the proposed technology ensures a decrease in annual operating costs by UAH 7 million (USD 185,000), and therefore an increase in the economy of ammonia production as a whole

The object of the study is the IOT system for monitoring the state of objects.
The problem being solved is the development of an innovative method of detecting and correcting data transmission errors in the networks of Internet of Things systems.
The essence of the results is that a method of detecting and correcting multiple transmission errors during byte-by-byte transmission of a block of information has been developed. The method is distinguished by an original coding scheme, which involves the calculation of control bits, as well as the shuffling of block bits by performing bit shift operations. The peculiarity of the method is that any bit can be distorted when transmitting a code word, but it belongs to different code combinations of the Hamming code. This allows multiple data transmission errors to be detected and corrected during decoding, and multiple errors of different bytes belonging to the same block can be corrected.
Simple algorithms for encoding and decoding procedures have been developed, and programs for information block encoding procedures and decoding procedures with error detection and correction have been developed. A software model of the data transmission channel was also developed with the possibility of introducing multiple errors when simulating the data transmission process. All programs are developed in Python, although other languages are possible.
An experiment was conducted using the developed software model of the data transmission channel. The efficiency of the developed method has been experimentally confirmed and it has been proven that its use increases the immunity of the data transmission channel. This is due to the fact that the developed method allows detecting and correcting all code word transmission errors with a multiplicity from 1 to 8, which was confirmed experimentally.
The main field of use of the developed method is considered to be IoT system networks. First of all, systems for monitoring the state of objects

This paper describes approaches to improving the efficiency of agricultural enterprises. It has been established that the use of technology transfer, in particular, precision farming technologies, makes it possible to enhance the efficiency of agricultural enterprises, in particular, to increase the yield of agricultural crops and, accordingly, to improve the profitability of enterprises. As an example, the activities of agricultural enterprises in the Republic of Kazakhstan were analyzed. The share of agricultural enterprises in the Republic of Kazakhstan that use elements of precision farming technology in their activities was determined. It was established that since 2019, the use of precision farming technologies in the activities of agricultural enterprises in the Republic of Kazakhstan has intensified. At the same time, from 60 to 75 % of enterprises already use elements of precision farming technologies in their activities. Using crop yield data for the past 32 years, estimates of the effectiveness of using precision farming technologies by agro-enterprises in the Republic of Kazakhstan were constructed based on forecasting yield indicators using the linear-weighted moving average method. The efficiency of using precision farming technologies in the activities of agricultural enterprises in the Republic of Kazakhstan in 2022 reached 8.46 %, and the average efficiency for the period 2019–2022 was 4.21 %. Therefore, the use of precision farming technologies makes it possible to improve the validity of decision-making in the management of an agricultural enterprise and to obtain a higher profit from the sale of produced agricultural products for any agricultural enterprise in the world. On average, the results allow us to estimate the possible profit of an agro-enterprise when growing agricultural crops in the case of using precision farming technology

The object of this study is to determine the economic effect of technology transfer during the period of its viability. This paper suggests a methodology that takes into account the appropriate amount of profit and the accumulated amount of royalties in the commercial use of innovative technology. The necessity of taking into account the viability of the transfer of innovative technology as the beginning of its new life cycle was substantiated. The possibility of formalizing this process in the form of an assessment of the sum of the present values of all projected cash flows, taking into account the eligibility criterion and the barrier rate, has been established. We propose an approach, which, unlike the existing ones, consists in allocating a certain period of viability of innovative technology transfer in the life cycle of technology. It is argued that based on the results of technology renovation, it is possible to assess the economic effect of its transfer due to the benefits of implementation and achievement of licensing activity by expanding the number of licensees. We substantiate the possibility of generating profits and royalties to the licensor as the amount of investment that can and should be directed to the development of a fundamentally new or improved technology in relation to the previous one. The transition to a new technology causes an increase in the overall technological level and leads to the formation of a technological gap between the S-shaped life curves of technical systems and, in parallel, forms a new S-shaped curve of a new technological system based on new knowledge. An economic and legal approach to the development of a methodology for determining the economic effect or viability of innovative-level TT was implemented. The results of the current study could be used in the formation of legislative and subordinate national regulations, as well as serve as a basis for further research on this issue

The problem solved is to determine safer and more effective technologies for post-harvest processing of fruits. To achieve the goal, lemon fruits (of different degrees of wilting) were cut crosswise, each piece was treated with miramistin and deсasan in concentrations of 0.1 %, 0.3 %, and 0.5 %. The samples were placed on agar blocks with pure cultures of pathogens and placed in wet Petri dishes, kept at a temperature of 25 °C in a thermostat for 6–10 days; the experiment was repeated three times. The research aimed to establish the concentration of antimicrobial drugs for treating lemons; determine the weight loss of lemon fruits depending on the storage temperature. The object of the study is the process of preserving the quality of lemon fruits during post-harvest treatment with antiseptics during cold storage.
It is proposed to treat lemon fruits with miramistin and deсasan in concentrations of 0.3 % and 0.5 % in order to inhibit the development of blue and green mold during storage. Damage to turgor fruits is two times less than that of weakly wilted ones. At a storage temperature of 10 °C, fruits are stored for 40–45 days. At the same time, daily losses are 0.49 %. Lowering the storage temperature to 4 °C extends the storage period to 90–100 days, with a daily mass loss of 0.08 %. A curvilinear correlation dependence of the second order of weight loss of lemon fruits on the duration of storage was established (R2=0.9758–0.9903).
Treatment with antiseptics makes it possible to implement environmentally friendly solutions that will make it possible to exclude chemically synthesized fungicides and preserve the natural properties of fresh citrus fruits after harvesting, as well as extend their shelf life. In the development of new, low-cost, environmentally friendly, and affordable technologies, this is an important technique
