Temperature variation in turbocharger casings of generator sets generates shocks and thermal fatigue that cause cracks in different areas, with permissible limits depending on the direction and location. This study analyzes the microstructure and chemical composition of nodular cast iron castings manufactured under ASTM A 536 and GOST3443-87 standards, using metallographic techniques and emission spectroscopy. With visual inspection and penetrating liquids, the types of cracks and their orientations are examined. The maximum amplitude of the thermal stress generated during the thermal shock was determined using MATLAB software, considering that for a minimum stress concentration factor (kf=1), the thermal stress amplitude is 560 MPa, exceeding the design limit of 210 MPa, which explains the appearance of transverse and longitudinal cracks. Transverse cracks show a higher thermal stress concentration factor than longitudinal cracks.

This paper presents a proposal for the creation of a knowledge base to serve as a starting point for training a real-time translation system between Nahuatl and Spanish using the Entity-Relationship Model (MER) for database design. In this model, entities and relationships are key elements, with mathematically defined attributes corresponding to specific domains. To implement this model, a specific methodology is followed, ranging from the determination of entities to the physical design of the database. Effective database design requires consideration of three essential elements: structure, relationships and integrity rules. These rules ensure that key values in relationships are defined and that attributes in one relationship properly correspond to others in a different relationship.

Solar energy is a natural resource that is used to generate electricity using photovoltaic technology, based on the photoelectric effect. Although useful, this technology faces challenges such as intermittency, environmental impact, installation costs, and energy storage. A specific problem is the dust that accumulates on the surface of the photovoltaic modules, the particles of which the dust is composed reduce their efficiency by absorbing or reflecting part of the solar radiation needed for the solar cells. To maintain the efficiency of the modules, it is essential to clean them regularly, using dry or wet cleaning methods. This research analyzes the factors that affect the performance of PV modules and compares the advantages and disadvantages of both cleaning methods. The results of the study indicate that wet cleaning is more effective in maintaining the optimal performance of PV modules.

STRUCTURAL SHIFTS IN GRAIN PRODUCTION IN RUSSIA IN THE POST-REFORM PERIOD
Authors:   Voronezh federal agrarian scientific center name after V.V. Dokuchaev (branch), Pechenevsky Vladimir Fedorovich
Published: February 2025

In our country, the grain problem has been and traditionally remains one of the main and most complex practically throughout its entire history. It is complex and multifaceted, since it simultaneously intertwines a variety of economic, organizational, technological, spatial, social and other issues. Over the years of market reforms, the grain industry has undergone large-scale changes compared to other sectors of agriculture, as a result of which Russia has expanded the spatial boundaries of the grain market, meeting the needs of the rapidly growing external world demand for grain. Over the past eight years, the annual gross harvest of grain crops in the country has not fallen below 100 million tons. The average annual growth rate of grain crop yields over these years was more than twice the world rate. In the post-reform years, there were significant structural shifts in the development of the industry: with an increase in yield, sown areas have significantly decreased and the sectoral (food and forage crops) and species structure of grain production has changed dramatically, the boundaries of the spatial organization of the placement of grain production have expanded; the ratios between the groups of grain food and forage crops have noticeably changed towards an increase in the share of the first group; in the structure of food crops, there is a tendency to decrease crops under cereal crops and rye and increase wheat crops; a significant reduction in crops of grain forage crops was accompanied by a certain improvement in their structure; there is a tendency towards instability and a decrease in the profitability of the grain sub-sector. Sustainable and effective development of the country's grain economy in the future will be associated with the implementation of a set of government measures aimed primarily at increasing the intensity of the industry and strengthening its material and technical base.

Published: February 2025

The purpose of the work is to develop methodological and practical provisions for financial analysis in audit activities in agricultural organizations, recommend measures to ensure and strengthen the financial condition. Financial analysis is one of the most complex tools used by auditors. Analytical procedures are one of the types of audit procedures that consist in identifying, analyzing and assessing the relationships between the financial and economic indicators of the audited economic entity. Their application is based on the existence of a clear cause-and-effect relationship between the analyzed indicators. Despite a significant number of publications on various areas of the problem under consideration, its scientific development is far from exhausted. Many theoretical and methodological issues related to financial analysis in auditing in agricultural organizations and forecasting based on an assessment of the financial condition have not been fully studied, and a number of provisions are debatable. As a result of the research, the main indicators of the financial and economic activity of the enterprise for three years were considered. In order to draw correct conclusions about the reasons for changes in the assets and liabilities of the enterprise, a comparative analytical balance was carried out.

Published: February 2025

The objective of this research was to evaluate the quality of training and qualification services offered by a public institution by comparing the expectations and experiences of the client, who is an administrative technician in education, and their relationship with satisfaction in the work environment and quality of life at work. The research is exploratory and descriptive in nature, and quantitative and qualitative methods were used. To evaluate the effectiveness of the training program at the Instituto Federal do Pará – Campus Avançado Vigia, the site of this research, the SERVQUAL model was used, which aims to measure the quality of the service based on the difference between the perceptions of the clients about the service provided and their expectations. It is a questionnaire composed of 22 questions that encompass 5 dimensions of quality, dimensions selected from bibliographical surveys, indicated as relevant for this study. The SERVQUAL model proved to be effective in evaluating the quality of the service and in identifying gaps that need to be addressed to improve the organization's performance. The relationship between perceived quality and satisfaction in the work environment was analyzed using the QWLQ-bref questionnaire, which assesses four domains of quality of work life (QWL). It consists of 20 questions, which makes the research faster. The results revealed a positive correlation between the dimensions of quality of the training service and the domains of QWL, corroborating the studies carried out and indicated in this research. The gaps between expectations and results related to the quality of the training service were also confirmed. As a suggestion for future research, it is suggested that the questionnaires be applied to other units of the federal public sphere with the aim of promoting generalization and reducing biases

HISTÓRIA, “DETERMINAÇÃO DO FATOR ECONÔMICO” E MÉTODO A PARTIR DE MARX
Authors: Santos Leonardo Moreira dos , Novais Liliane Capilé Charbel
Published: February 2025

The present article aims to present the concept of history and the debate on the "determination of the economic factor" from the perspective of Marx and Engels, relating them to each other and establishing their importance in constructing a research method based on the social theory founded by the two authors. To this end, it explores the understanding of the ontology of social being and the social structures of class societies, arguing that the categories of alienation, commodity fetishism, and reification are crucial for understanding the relationship between human praxis and the social structures of societies divided into social classes. Thus, these categories serve as an indispensable heuristic key to avoid structuralist or overly simplistic readings of reality. The methodology adopted is a literature review based on research on the subject.

Published: February 2025

In this study, we report the possibility of an intelligent microfluidic system for manipulating an active object (sperm). In this system, we assumed that the sperm was manipulated owing to the flow generated by pneumatic microvalve actuation. Thus, it was considered that the sperm could be transported toward the intended target area if the valve phase was changed appropriately. However, the complexity of task prevents humans from developing a plan for switching the valve phases. To overcome this complexity, we used a policy model (agent) for valve actuation that was trained based on deep reinforcement learning. However, training an agent in a real environment requires considerable time. Therefore, we constructed a training simulator on a computer to train the agent. Thereafter, we investigated whether agents can be trained to manipulate sperm at different movement speeds. The study showed success in the training of agents for the control of sperm movement.

Authors: Hayakawa Masaru , Tanaka Hirohumi , HASEGAWA Tsuyoshi
Published: February 2025

In this study, we examined whether a Cu-doped Ta2O5 reservoir can accept direct optical signal input and classify the optical input patterns. Four optical patterns of alphabetical characters were classified with the high accuracy of about 99%, utilizing both of the photoconductivity and the ionic conductivity of Cu-doped Ta2O5. Classification accuracy higher than 85% was achieved even when we irradiated rotated patterns or changed the light intensity. Wavelength dependence was also examined, where the visible light separated into four bands of 100 nm in width by band-path filters was accurately classified, although it was difficult in our previous study using a Ag2S reservoir. Furthermore, we demonstrated the recognition of sequentially input optical pattern trains with a Cu-doped Ta2O5 reservoir. In this case, trains of three alphabetical characters were successfully classified just by using outputs measured at a readout point after finishing the input.

Published: February 2025

Surface tension plays an important role in the micrometer-sized fluid interface, but only a few methods can measure it remotely. On spatially restricted surfaces, plural eigenmodes of thermally induced capillary wave resonance are observed, and their resonant frequencies depend on the surface tension. Incident laser light is scattered by the capillary wave with Doppler shift. The resonant peaks corresponding to the eigenmodes are observed in the power spectra. In this study, a spectrum fitting algorithm utilizing the theoretical frequency ratio of the plural eigenmodes is proposed. In addition, the position dependence of the fitting quality on the position along the diameter axis was also investigated. As a result, the algorithm worked well in the circular center area. This algorithm and knowledge will be valuable for various applications such as environmental and biological surface science.

Authors: Iemura Hikaru , Uomoto Miyuki , Shimatsu Takehito
Published: February 2025

Blade tests of bonded interfaces created by atomic diffusion bonding of wafers using Zr and Al2O3 films were conducted in air (50% relative humidity RH), dry air (RH less than 2%) and Ar gas. We assessed the variation of the surface free energy γ at the bonded interfaces, as calculated for convenience from the debonding length. Although γ measured in air decreased remarkably from the initial value, γ measured in Ar and dry air maintained the same initial value for a while, suggesting that moisture content plays a main role in the γ decreasing caused by water stress corrosion.

Case Report of Transverse Colon Volvulus with Classic Radiological Findings
Authors: Mernissi M. , Aboulfeth E. M. , Abdellaoui M.
Published: February 2025

Transverse colon volvulus (TCV) is a rare but serious cause of large bowel obstruction, and its diagnosis relies heavily on imaging. While plain radiographs can suggest the diagnosis, contrast-enhanced computed tomography (CT) is the gold standard for confirming TCV and assessing complications such as ischemia and perforation. We present a case of TCV in a 27-year-old male presenting with acute abdominal pain, vomiting, and abdominal distension. Imaging revealed the characteristic "coffee bean" sign and "whirl sign" of the transverse colon on CT, confirming the diagnosis. Given the absence of imaging features suggesting complications, the prognosis was improved, allowing for a non-emergency approach to surgical management. The patient subsequently underwent a subtotal colectomy due to the significant dilation of the colon, in order to prevent potential recurrence. This case underscores the crucial role of imaging, particularly CT, in diagnosing TCV.

Authors: Gultom Suryani
Published: February 2025

Kegagalan kemitraan dalam agribisnis sering kali disebabkan oleh berbagai kelemahan para pelaku agribisnis, seperti lemahnya aturan, mekanisme, dan manajemen kelembagaan kemitraan. Selain itu, keterbatasan petani dalam permodalan, teknologi, informasi, dan akses pasar menyebabkan mereka kurang mandiri dalam mengelola usahatani, sehingga lebih mudah tersubordinasi oleh pihak yang lebih kuat. Penelitian ini bertujuan untuk menganalisis pola interaksi kemitraan serta jaringan kelembagaan dalam produksi dan pemasaran agrosilvopastura. Metode yang digunakan adalah pendekatan kualitatif deskriptif dengan teknik wawancara mendalam menggunakan metode snowball sampling terhadap 10 informan, termasuk 3 informan kunci. Hasil penelitian menunjukkan bahwa pola interaksi kemitraan yang diterapkan dalam sistem agrosilvopastura adalah Pola Inti Plasma, di mana terdapat hubungan antara petani kecil sebagai mitra dan perusahaan inti sebagai pengelola utama. Selain itu, jaringan kelembagaan dalam kemitraan ini terbagi menjadi dua pola utama yang berperan dalam distribusi dan pemasaran. Kesimpulan dari penelitian ini menekankan pentingnya penguatan kelembagaan masyarakat agar petani lebih mandiri dalam mengelola usahatani serta memiliki daya tawar yang lebih kuat dalam kemitraan agribisnis.

Authors: Kristine Dyan L. Zabala
Published: February 2025

This study focused on the persuasive language used by students in academic misconduct and to probe how these persuasive languages assess the fairness and integrity of the incident review. This study aimed at unveiling the persuasive language and the persuasive strategies employed by students in the observed five cases of academic misconduct and emerging themes focused on the conviction of the school disciplinary authorities from the incident review. Through purposive sampling, five cases of academic misconduct on cheating, loitering, bullying, cutting classes and stealing served as the corpora of the study. While seven school disciplinary authorities served as participants in this research. Consequently, appeal to pathos was the predominant persuasive language employed by students in their academic misconduct. Moreover, the results showed five emerging themes as regards to the students’ persuasive language used in their academic misconduct, minimization of misconduct, externalizing responsibility, denial and shifting blame, justification through promises and victimization rhetoric. Additionally, the response of school disciplinary authorities on persuasive language employed by students during incident review resulted to five essential themes, namely, evaluation of persuasive language, institutional and policy guidelines, fairness vs. empathy in decision making, bias and equity in the disciplinary process and collaboration with stakeholders in evaluating justifications. Lastly, identified authorities affective responses along with the disciplinary actions as to the ways on which students’ persuasive language shape the result of the incident review. Results revealed namely emphasizing integrity and accountability, disappointment, neutrality, doubt, and encourage self-reflection and change. The key findings of this qualitative study opened the door in understanding these strategies and inform the development of targeted interventions to promote academic integrity and ethical decision-making in educational settings.
