A neural network approach to predicting the quality indicators of the purification department of a sugar factory
Authors: Zaiets N. , Lysenko N. , Vlasenko L.
Published: November 2024

The article proposes a model of the defecosaturation department of a sugar beet processing plant based on a neural network, which predicts the main indicators of the efficiency of diffusion juice purification. The predictive model allows you to adjust the operation mode of the department by analyzing the unmeasured qualitative indicator of the purification effect. The developed model also predicts the color of the semi-finished product, as well as the loss of sugar in the filter cake I and II saturation with an error of less than 5%. Unlike existing solutions, forecasting is performed in real time using a set of indicators of an automation system and an industrial laboratory. A predictive neural network model is an MLP universal for approximating non-linear complex functions with many variables. The model has 32 inputs, 4 outputs and one hidden layer with 23 neurons. The main technological variables from the automation system – temperatures, flow rates, pressure, pH in the apparatus, as well as from the industrial laboratory – alkalinity, SO content in the saturation gas will be fed into the network input. This allows to increase the informative support of the operator-technologist regarding the quality indicators of the enterprise without additional load on the industrial laboratory and without additional cost automatic quality devices.

Analysis of approaches to the use of intermediate crops as feedstock for biomethane production in Ukraine
Authors: Zheliezna Т. , Drahniev S.
Published: November 2024

The wide use of renewable energy sources, in particular biomass, makes a significant contribution to the decarbonization of the energy and transport sectors. Today, one of the most promising directions for the development of European and Ukrainian bioenergy is the production and consumption of biomethane. Biomethane can be used both, as a direct substitute for natural gas in the production of heat and electricity, and as motor fuel. The priority development of biogas/biomethane production is indicated in the European Green Deal, which the EU has been following since the end of 2019. Special attention is paid to the issues of sustainable development of bioenergy, including the use of sustainable feedstock for obtaining all types of biofuels. Because of this, the new version of the EU Renewable Energy Directive of 2023 (RED III) strengthened the sustainability requirements for the production of liquid biofuels and biogas for transport. One of the sustainable types of feedstocks for the production of biomethane can be biomass of intermediate crops, which are plants that are grown in the time interval free from the cultivation of main crops in the crop rotation.

All the mentioned issues are relevant and important for Ukraine as a member of the Energy Community and a potential member of the EU, which will join the implementation of the European Green Deal in the future.

The purpose of the work is to assess the potential of biomethane production from intermediate crops in Ukraine and to develop some preliminary recommendations for the development of this sector.

The assessment of the potential was carried out using the conservative approach described in the study by experts of Ghent University (Belgium). It is assumed that 20% of the total sown area can be allocated for the cultivation of intermediate crops. The obtained results show that even with a conservative approach, the potential for biomethane production from intermediate crops is the largest component of the total potential for obtaining biomethane from various feedstocks in Ukraine, namely 9.29 billion m3 CH4/y, which is 47% of the total potential. This points to very good prospects for the development of this bioenergy sector in the country.

When elaborating preliminary recommendations for the introduction of biomethane production from intermediate crops in Ukraine, main principles of Biogasdoneright, the European model of sustainable agriculture development were taken into account. Ukraine’s natural-climatic and soil-water conditions have been analysed from the viewpoint of possibility and effectiveness of growing intermediate crops for bioenergy. Some types of agricultural crops for sequential cultivation and possible crop rotations have been suggested. The directions of further research, scientific and practical work necessary for the development of this bioenergy sector in Ukraine have been determined.

Authors: Shvorov S. , Opryshko O. , Dudnyk А. , Tsitsyurskii Y. , Zaloznyi R.
Published: November 2024

The relevance of the work lies in the fact that in the conditions and after the end of the war, many elements of weapons and military equipment remain on agricultural fields. In order to avoid collisions of agricultural machinery with these elements, the following tasks are solved with the help of the proposed system: monitoring of the field based on the use of space and unmanned aerial vehicles, planning of fieldwork, and synthesis of the routes of movement of unmanned tractors and combines, as well as control and operational management of their modes of operation. Based on information from the sensors of space and aircraft using special software, a microrelief of the field is constructed, and the coordinates of dangerous elements (obstacles) in the path of unmanned vehicles are determined. In addition, water erosion of the soil is monitored at this stage. The compromise-optimal routes and movement parameters of unmanned tractors for plowing and fertilizing the land are determined in the second stage. In the third stage, the volume and density of the crop in each field section are specified. The coordinates of obstacles to implementing the compromise-optimal movement trajectories and unmanned harvesters' optimal speed of movement combine harvesters during harvesting.

Expanding Horizons: Increasing Injectable Vaccine in the Expanded Program on Immunization
Authors: Gupta Birendra Prasad , Ghimire Namita
Published: November 2024

The World Health Organization started the Expanded Program on Immunization in 1974, including 6 antigens with up to 8 vaccine doses for childhood vaccination. The number of antigens has now increased to 11 antigens in 21 vaccines. The expansion of vaccination programs to include more antigens and doses has led to concerns about the burden of multiple injections on infants and children, as well as factors such as fear of adverse reactions, pain, and overall acceptability of vaccines. To address these challenges, there's a call for research to focus on developing combined vaccines that can be administered through more acceptable routes, such as oral, nasal, or needleless administration. This approach could potentially reduce the number of injections required and increase the willingness of individuals to receive vaccines. We highlight the importance of ongoing research and innovation in vaccine development and delivery methods to ensure that vaccination programs remain effective, efficient, and acceptable to the communities they serve, particularly in resource-limited settings.

Published: November 2024

Introduction: The dural venous system, composed of various sinuses, plays a crucial role in draining deoxygenated blood from the central nervous system. Understanding its anatomical variations is essential to differentiate it from pathological conditions like cerebral venous sinus thrombosis. This study aims to evaluate the anatomical variations of the dural venous sinuses using Magnetic Resonance Venography.Methods: An observational, cross-section study was performed in the Department of Radiology from September 2023 to March 2024 after the approval by the Institutional Review Committee (Reference number: 149/080/081(6-11)E2). Magnetic Resonance Venography of 109 adult patients was performed using a 1.5 Tesla MRI scanner. Diameters of the superior sagittal sinus, straight sinus, and transverse sinuses were measured. Variations in transverse sinuses, straight sinus, and confluence were categorized and analyzed. Results: The study included 52 (47.70%) male and 57 (52.30%) female, with median age of 42 (IQR: 30.5 - 56) years. The superior sagittal sinus had the diameter of 6.4±1 mm. Symmetric transverse sinus variant seen was in 80 (73.39%) patients, and left transverse sinus hypoplasia was seen in 20 (18.35%) patients. Variations in the straight sinus and confluence were also documented with a true confluence (type III) was seen in 71 (65.10%) patients.Conclusions: Anatomical variations of the dural venous sinuses as observed in 1.5 Tesla MRI was quite common.

Authors: Basnet Suman Kumar , Shrestha Prakash , Bajracharya Gaurav Bir
Published: November 2024

Ulnar neuropathy is a common peripheral neuropathy, with cubital tunnel compression being the second most frequent upper extremity compression syndrome. Ganglion cysts, though rare, can contribute to ulnar nerve compression in the cubital tunnel. Here, we present a case of a 62-year-old farmer with longstanding diabetes and dyslipidemia who experienced progressive pain and numbness in his medial fingers, exacerbated by elbow flexion. Initially misdiagnosed and treated for Hansen’s disease. Clinico-radiological evaluation revealed a multiloculated cystic lesion in the posteromedial aspect of his left elbow, compressing the ulnar nerve. Surgical excision of the ganglion cyst alleviated symptoms, though residual motor deficits persisted postoperatively. This case underscores the importance of considering ganglion cysts in the differential diagnosis of cubital tunnel syndrome, highlighting the diagnostic challenges and therapeutic considerations in managing this rare etiology.

Published: November 2024

Introduction: Hip and knee arthroplasty surgeries are essential for treating end-stage osteoarthritis, providing significant functional improvements. Despite a global rise in these procedures, Nepal lacks a National Joint Registry, resulting in a gap in tracking the exact number of surgeries, outcomes, and complications. This study aims to address this gap regarding the demographics of hip and knee arthroplasties in Nepal.Methods: An observational study was conducted after obtaining the ethical approval from the Nepal Health Research Council (Reference number: 2024/136)  with data collected from prosthesis supplier. The study included all primary hip and knee arthroplasties performed in 2022 and 2023, excluding revision cases and those requiring mega prostheses. Data analysis was performed using Microsoft Excel for descriptive statistics.Results: There were a total of 1259 surgeries, 916 (72.77%) total knee replacements were performed, with a female predominance of 741 (81.42%) and a median age of 67 years(IQR: 62-71). There were 343 (27.23%) total hip replacements surgeries of which 200 (58.31%) were done in males. Most surgeries 1148 (91.18%) occurred within the Kathmandu Valley.Conclusions: Total knee arthroplasty accounted for the majority of cases, showing a predominance of female patients with the majority of surgeries in the capital city.
Regulacje państwowe z 1858 roku dotyczące nakładania pokuty kościelnej na obszarze Królestwa Polskiego
Authors: Wolnicki Paweł
Published: November 2024

Ustawodawca Królestwa Polskiego, wprowadzając Kodeksem kar głównych i poprawczych od 1848 r. pokutę kościelną, nie określił procedury ustanawiania takiej pokuty w konkretnym przypadku. Dostrzegając różnorodność stosowanych praktyk, Komisja Rządowa Sprawiedliwości wystąpiła do właściwej w sprawach wyznaniowych Komisji Rządowej Spraw Wewnętrznych i Duchownych w sprawie uregulowania tej kwestii. Efektem było zredagowanie w 1858 r. aktu: Wskazanie władzom duchownym zasad i form do wykonywania kary pokuty kościelnej. Miały one charakter instrukcji wprowadzonych do krajowego porządku prawnego rozporządzeniem władz państwowych. Celem niniejszego artykułu jest omówienie tego dokumentu i ocena jego wpływu na instytucje kościelne oraz na podsądnych skazanych na pokutę kościelną na podstawie przepisów karnych.  Przeprowadzone analizy skłaniają do wniosku, że wytyczne odnoszące się do procedury nakładania pokuty kościelnej odznaczały się dużą dozą ogólności i nie zabezpieczały należycie praw podsądnego w zakresie wolności sumienia i wyznania. Nie dawały także gwarancji prawnej ochrony wolności Kościołów chrześcijańskich w wymiarze wspólnotowym. Stały się instrumentem służącym podporządkowaniu instytucji kościelnych i członków wyznań chrześcijańskich, przede wszystkim katolików, polityce wyznaniowej caratu.

«Иго Господне благо…» Феофилакта Лопатинского в богословских спорах начала XVIII в.
Authors: Рогожин Александр Александрович
Published: November 2024

В богатой на события первой трети XVIII в. особую роль сыграл богословский спор об оправдании верой, развернувшийся между Феофаном Прокоповичем и Стефаном Яворским и его сторонниками. К числу последних относился ректор Славяно-греко-латинской академии и архимандрит Заиконоспасского монастыря в Москве Феофилакт Лопатинский. Феофилакт написал в ответ на «еретическую», по его мнению, «Повесть о распре Павла и Варнавы с иудействующими» Феофана свое сочинение «Иго Господне благо...». Посвященное, строго говоря, частному вопросу, «Иго Господне благо» превратилось, благодаря впечатляющей эрудиции Феофилакта, в фундаментальный богословский трактат объемом в несколько сотен страниц. Тем не менее, трактат так и не был напечатан, циркулируя в рукописях. В фонде Синода в РГИА остались авторские черновая, а также первая часть чистовой версии сочинения. В работе мы использовали рукописи сочинения, относящиеся ко второй половине XVIII в., в первую очередь из Собрания Московской духовной академии Отдела рукописей РГБ. Цель работы состоит в прояснении основных доводов и риторических приемов Феофилакта, направленных на обоснование «еретичества» оппонента. По итогам исследования можно прийти к выводу, что Феофилакт опасался распространения «еретического мнения» в первую очередь с точки зрения последствий для прочности церковной и государственной организации.

In the eventful first third of the 18th century, the theological dispute about justification by faith that unfolded between Feofan Prokopovich and Stefan Yavorsky and his supporters played a special role. «Supportes» included the rector of the Slavic-Greek-Latin Academy and archimandrite of the Zaikonospassky Monastery in Moscow, Feofylact Lopatinsky. Feofylact wrote in response to Feofan's «heretical», in his opinion, «The Tale of the Contention of Paul and Barnabas with the Judaizers» his essay «The Yoke of the Lord is Good...». Dedicated, strictly speaking, to a particular issue, «The Good Yoke of the Lord» turned, thanks to the impressive erudition of Feofylact, into a fundamental theological treatise of several hundred pages. However, the treatise was never published, circulating in manuscripts. The author's draft, as well as the first part of the final version of the work, remained in the Synod's collection at the Russian State Historical Archive. In our work, we used manuscripts of the work dating back to the second half of the 18th century, primarily from the Collection of the Moscow Theological Academy of the Manuscripts Department of the Russian State Library. The purpose of the work is to clarify the main arguments and rhetorical techniques of Feofylact, intended to proving the «hereticism» of his opponent. Based on the results of the study, we can come to the conclusion that Feofylact was afraid of the spread of «heretical opinion», primarily from the point of view of the consequences for the strength of the church and state organization.

Spatial planning is already a standard government tool that is made periodically at the National, Provincial, District and even Village levels, however, this tool often loses its meaning and function due to inappropriate approaches and manufacturing processes. This is mostly caused by a lack of human resource capacity and skills, and mapping skills that have not been mastered by government officials at the basic level, including at the kelurahan and sub-district levels. It is necessary to present geospatial information using maps and disseminate it from the highest level of government to the lowest village/kelurahan level. As one of the administrative areas of Siabu Village, Salo District, Kampar Regency, it still has problems in conducting administrative mapping of its area due to the absence of competent personnel and the absence of digital mapping skills by utilizing geographic information system technology. This community service activity is to provide counseling regarding digital mapping based on geographic information systems for Siabu Village apparatus. The methodology for implementing this activity consists of the preparation, socialization, implementation and evaluation stages. By carrying out this counseling, it can help the surrounding community as well as provide information in the administrative mapping of the area in Siabu Village. For the next program, it is important to conduct counseling by directly surveying the condition of Siabu Village. Apart from that, the provision of a map of Siabu Village to Siabu Village Apparatuses is expected to help Siabu Village apparatus. By carrying out this counseling, it is hoped that the Siabu Village apparatus can understand digital mapping methods based on geographic information systems that can help the performance of Siabu Village apparatus.

Examples of singular and nonsingular systems of vari-ous dimensions that arise when processing magnetometric and gravimetric data from experimental observations are discussed. Conclusions are drawn about methods for constructing an optimal net-work of experimental observation points.
Algorithms for optimizing systems with multiple extremum functionals
Authors: Tolstykh V. K.
Published: November 2024

The problem of minimizing (maximizing) multiple extremum functionals (infinite-dimensional optimization) is considered. This problem cannot be solved by conventional gradient methods. New gradient methods with adaptive relaxation of steps in the vicinity of local extrema are proposed. The efficiency of the proposed methods is demonstrated by the example of optimizing the shape of a hydraulic gun nozzle with respect to the objective functional, which is the average force of the hydraulic pulse jet momentum acting on an obstacle. Two local maxima are found, the second of which is global; in the second maximum, the average force of the jet momentum is three times higher than in the first maximum. The corresponding nozzle shape is optimal. Conventional gradient methods have not found any maximum; i.e., they were unable to solve the problem.
Algorithms for solving the inverse scattering problem for the Manakov model
Authors: Belaiа O. V. , Frumin L. L. , Chernyavsky A. E.
Published: November 2024

The paper considers algorithms for solving inverse scattering problems based on the discretization of the Gelfand–Levitan–Marchenko integral equations, associated with the system of nonlinear Schrödinger equations of the Manakov model. The numerical algorithm of the first order approximation for solving the scattering problem is reduced to the inversion of a series of nested block Toeplitz matrices using the Levinson-type bordering method. Increasing the approximation accuracy violates the Toeplitz structure of block matrices. Two algorithms are described that solve this problem for second order accuracy. One algorithm uses a block version of the Levinson bordering algorithm, which recovers the Toeplitz structure of the matrix by moving some terms of the systems of equations to the right-hand side. Another algorithm is based on the Toeplitz decomposition of an almost block-Toeplitz matrix and the Tyrtyshnikov bordering algorithm. The speed and accuracy of calculations using the presented algorithms are compared on an exact solution (the Manakov vector soliton).
Calculating a perturbation of a plasma layer by an electric field
Authors: Gordeeva N. M.
Published: November 2024

The paper presents the results of solving a boundary value problem for a system of two integro-differential equations that simulate the action of an external electric field on a plasma layer. This system is an implication of the Boltzmann–Maxwell equations, and the physical meaning of the sought functions is the strength of a self-consistent electric field and perturbation of the electron distribution density. The solution of the problem is constructed using the theories of Fourier transform of generalized functions and singular integral equations with the Cauchy kernel. The dependence of the solution on the frequency of the external field is studied.

Authors: Nosikov I. A. , Tolchennikov A. A. , Klimenko M. V.
Published: November 2024

A direct variational method for solving the problem of reflection of ocean waves ray paths from the coastline with given positions of the source and the point of registration is considered. It is shown that the original boundary value problem can be reduced to the direct search of stationary points of the functional. Information about the objective function in the area of solutions of the ray problem allows us to construct a systematic procedure for finding minima and saddle points. A feature of the proposed approach is the optimization of the ray reflection point along a given coastline.

Published: November 2024

This study aims to obtain information about French Language Education Study Program students' perception of using multimodal texts in Réception Écrite (RE) learning or reading, followed by a needs analysis of multimodal text-based teaching materials. Réception Écrite learning is currently carried out using the book Alter Ego Plus A1. The book is not multimodal. Therefore, it is necessary to develop teaching materials for multimodal-based Réception Écrite courses. Questionnaires were employed to get students' perceptions of the need for multimodal-based Réception Écrite teaching materials. The respondents to this questionnaire were 40 students for the 2021 academic year. The questionnaire employed has been validated by experts. The data obtained from the questionnaire were analyzed using descriptive statistics by calculating percentages. Generally, students already knew and understood a multimodal text. However, in the Réception Écrite course, only 40% of students studied multimodal texts. Students agreed to the use of multimodal texts. They needed multimodal-based Reception Ecrite teaching materials because, currently, there were no multimodal-based textbooks in the French Language Education Study Program. The development of multimodal-based teaching materials in the Réception Écrite course in the French Language Education Study Program must be carried out because this learning provides many benefits to students and lecturers. Benefits for students include interesting, easy to understand, not boring, encouraging students, fun, and others
