Item type:Документ, Access status: Open Access , Turning Research of a Sowing Unit Based on Reversible Tractor(Nitra : Paradigm Publishing Services, 2024) Findura, Pavol; Kollárová, Katarína; Nadykto, Volodymyr; Kyurchev, Volodymyr; Zhokin, Ivan; Надикто, Володимир Трохимович; Кюрчев, Володимир Миколайович; Жокін, Іван ОлександровичEN: Modern sowing machine-tractor units (MTU) can be divided into single-machine (single-module), two-machine (double-module), and three-machine (triple-module). The firsts, consisting of a tractor and a trailed/mounted seeder, are the most studied and, therefore, the most widespread. Two-module MTUs mainly use trailed or semi-mounted hitch and trailed seeders. The units of this type have been studied less. Three-module sowing complexes are even less common. Most are based on a trailed hitch and trailed seeders placed behind the tractor. There are samples of MTU with side-mounted seeding machines, but their knowledge is extremely insufficient. This paper examines a three-module MTU based on a tractor with reverse motion and a front semi-mounted hitch. One of the problems in using this sowing unit is the choice of design parameters that would ensure safe turning when manoeuvring on the headland. Theoretical and experimental studies have established that by increasing the side seeder's towbar length, MTU's safe turning under analysis with machines of a larger operating width can be performed with a smaller distance between their inner wheels and tractor's wheels (parameter d). If the coincidence condition of side seeders' wheel axes with the tractor wheels axe is met, an increase in the tractor track from 1.7 to 2.5 m allows for a decrease in the value of the distance d. This solution is especially effective when using seeders with an operating width of 3.6 m. In this case, the indicated decrease reaches a fivefold size, from 0.5 to 0.10 m. With the seeders' operating width of 5.4 m, the distance d can only be reduced by 1.4 times. But with this option for sowing MTU, it is possible to use a tractor with dual rear tyres and a parameter d value of 0.98 m. Actual oscillations in the distance d value within 0.28 ±0.01 m in the process of turning the studied sowing machine-tractor unit at a velocity of 2.2 m·s-1 are characterized by low variance (0.64·10-4 m2) and low (no more than 1.75 Hz) frequency. This allows us to consider this MTU's mode movement on the headland quite safe.Item type:Документ, Access status: Open Access , Accessibility and Responsibility: Use of Generative AI by Ukrainian Students(Novi Pazar : UIKTEN, 2025) Sharov, Sergii; Tereshchuk, Serhii; Romas, Liudmyla; Zemlianska, Alina; Derkachova, Olga; Saregar, Antomi; Шаров, Сергій ВолодимировичEN: The article highlights the results of a survey of students at Ukrainian universities on the use of artificial intelligence (AI) systems in the educational process. The main advantages and risks of using generative AI in education have been analyzed. For collecting data, a questionnaire created with Google Forms was used. There were 177 students from different regions of Ukraine who participated in the survey. It has been found that the vast majority of respondents (94.4%) use AI to perform various educational tasks. The most common AI services among students turned out to be ChatGPT, Gemini, MidJourney and DALL-E. It has been found that Ukrainian teachers allow the use of ChatGPT in classes with certain restrictions and instructions. 90.4% of students adhere to the principles of academic integrity and process the text generated by ChatGPT. Further research is planned to determine the possibilities of ChatGPT for developing critical thinking through reading and writing.Item type:Документ, Access status: Open Access , Hybrid Technology of Beet Pulp Dewatering with Process Intensification in a Convection Dryer as an Element of Sustainable Processing of Agro-Industrial Waste into Bioenergy(Basel : MDPI, 2025) Palamarchuk, Igor; Priss, Olesia; Zozulyak, Oksana; Kiurcheva, Liudmyla; Dyadyura, Konstiantyn; Romanowska-Duda, Zdzislawa; Vasylenko, Oksana; Obraniak, Andrzej; Hutsol, Taras; Паламарчук, Ігор Павлович; Прісс, Олеся Петрівна; Кюрчева, Людмила МиколаївнаEN: In the studied process of moisture removal there is an increase in the driving force, due to centrifugation during rotor rotation, the emergence of electroosmotic pressure when creating conditions for one-sided diffusion, the filtering of the technological mass of the load through the rotor perforations, as well as the introduction of low-frequency oscillations of the dryer’s actuators. Therefore, the purpose of this scientific study is to substantiate the operating modes of the vibration convective dryer by evaluating the amplitude–frequency parameters of the beet pulp dehumidification process. According to the results of the studies, the use of the angular velocity of the drive shaft of the vibrator in the range of 80. . .110 rad/s and the amplitude of oscillations within 2.5...3.0 mm allow the process to be carried out at maximum energy consumption of about 700...750 W. The developed technology involves the sequential implementation of vibration, filtration, and electroosmotic technological action, which allows for a reduction in the duration of beet pulp processing during dehumidification by almost two times compared to the duration when performing filtration moisture removal in a stationary layer of products. Low-frequency oscillations with force field acceleration (of the order of 2. ..3 g) are used to create a pseudo rapid layer of products before convective processing, and when this parameter is reduced to (0.9. . .1.0 g), they ensure maximum compaction of the pulp mass, which significantly increases the efficiency of electroosmotic moisture removal. Such a combination of the noted physical and mechanical factors makes it possible to reduce the specific energy consumption for the removal of 1 kg of moisture by 2.7 times compared to traditional convective drying.Item type:Документ, Access status: Open Access , AI Era in Reporting and Managerial Accounting: Implications, Pitfalls and Potentials(Cape Coast : Technical University, 2025) Sakhno, Lіudmyla; Tkal, Yarmila; Sushko, D.; Ocheret'ko, Larysa; Shevchenko, Y.; Сахно, Людмила АнатоліївнаEN: Purpose: The objective of this inquiry was to ascertain the extent to which technological paradigms have been institutionalised in accountancy and its concomitant practices, as well as to elucidate the pivotal determinants influencing the pragmatic assimilation of artificial intelligence technologies. Design/Methodology/Approach: The research employed methods of analysis, synthesis, induction, systematisation, and survey administration. An integrative review methodology was applied to the theoretical research (a sample of 31 entries), and a survey method was used for the empirical study (a sample of 947 participants). The sampling for the integrative review was conducted through searches across a range of scientometric databases: Wiley, JSTOR, and MDPI. Survey sampling was conducted on Facebook by issuing an announcement inviting representatives of the accounting sector to participate. Findings: It revealed a pronounced polarisation in technological receptivity, oscillating between enthusiastic embrace of innovation and latent resistance rooted in apprehensions of algorithmic encroachment on professional identity. Problematization is further compounded by a gnoseological asymmetry between developers of digital architectures and practitioners in the accounting sphere, necessitating the institutionalisation of interdisciplinary dialogue to foster a synergistic understanding of the permissible thresholds of technological intrusion into analytical processes. Research Limitation: The authors foreground the epistemological disjunction between the latent potentialities of intelligent technologies and the methodological inertia pervading the professional milieu, as manifested in the fragmented and uneven implementation of AI across stakeholders in the accounting-analytical continuum. Practical Implication: The synthesis of investigative outcomes substantiates the imperative to renovate the normative-methodological foundations of professional accounting education, invigorate the trajectory of technological acculturation, and implement evaluative-criterial models tailored to the cultivation of digital intuition. Social Implication: Central to the authors’ conceptual posture is the proposition that intellectual capital plays a constitutive role in adapting to the digital hyper-reality, in which AI functions not merely as an instrumental appendage but as a structural agent of paradigmatic managerial transformation. Originality/Value: The preponderance of exogenous macroeconomic vectors at the current phase of corporate evolutionary trajectory necessitates a paradigmatic recalibration of the juridico-regulatory scaffolding governing fiscal proceduralism within the technologised informatic context.Item type:Документ, Access status: Open Access , Design parameters justification of the plough bottom’s landside(SGGW : Nature portfolio, 2025) Nadykto, Volodymyr; Horetska, Iryna; Kyurchev, Volodymyr; Golub, Gennadii; Kielbasa, Pawel; Pidlisnyj, Vitaliy; Hutsol, Taras; Надикто, Володимир Трохимович; Кюрчев, Володимир МиколайовичEN: The use of a plough is characterized by the presence of a turning moment acting in a clockwise direction. When placing the plough resistance center to the left of the tractor’s longitudinal symmetry axis, it becomes possible to use the plough with one landside placed on its last bottom. The article presents a new analytical dependence that allows determining the design and technological parameters of the plow using the transverse displacement of the center of resistance to the left of the tractor’s longitudinal axis of symmetry. Studies have shown that using a plough with one landside instead of five does not affect the ploughing depth and the operating width. At the statistical significance level of 0.05, the null hypothesis about the equality of the mean values and variances of these parameters’ oscillations is not rejected. The normalized correlation functions and spectral densities of these processes’ oscillations are approximately the same. Using a plough with one landside instead of five leads to a 10.3% decrease in draft resistance, accompanied by a 10% decrease in specific fuel consumption. This study fills a gap in the practical operation of plows, aimed at reducing their draft resistance, which is key in reducing fuel consumption.
