Netebaon joi: La semiótica cósmica shipibo-konibo
Authors: Favaron Peyón Pedro Martín
Published: January 2025

El presente artículo plantea una reflexión semiótica desde una perspectiva shipibo-konibo, de la Amazonía peruana. Desde la comprensión de los sabios amerindios, todos los seres vivos (tanto del mundo sensible como suprasensible) participan del lenguaje; aunque cada especie lo hace de manera diferente, existe la posibilidad, incluso, de entablar diálogos entre las diversas formas de vida. Este artículo propondrá que la figura de los dueños espirituales (llamados ibo en la lengua shipibo), ocupa un rol fundamental en este dialogismo cósmico y, por eso, pueden ser entendidos como mediadores semióticos. Aunque estas reflexiones amerindias no se suelen plantear de manera explícita, son rastreables en ciertos enunciados cotidianos, así como entre las concepciones narrativas y las prácticas de los médicos visionarios de este pueblo amazónico. Estos enunciados y prácticas permiten reflexionar sobre una semiótica cósmica indígena, la cual, a su vez, vehiculiza nociones ontológicas amerindias que divergen del paradigma naturalista moderno. Sin embargo, sí es posible hallar ciertos vínculos con algunas proposiciones de la ciencia contemporánea (en particular, de la biología) que permiten empezar a trazar un modo distinto de comprender el lenguaje humano y la naturaleza comunicativa del cosmos.
La ayahuasca como tema y recurso narrativo en dos novelas peruanas: "Las tres mitades de Ino Moxo y otros brujos de la Amazonía y Puka Allpa. Viaje hacia la selva invisible"
Authors: Penenrey Navarro Julio
Published: January 2025

Este artículo tiene como propósito rastrear el papel que como tema y recurso narrativo cumple la ayahuasca en dos novelas peruanas con vínculos estrechos en los saberes ancestrales, el vegetalismo indígena y el pensamiento vegetal amazónico. Las tres mitades de Ino Moxo y otros brujos de la Amazonía, de César Calvo (1981), y Puka Allpa. Viaje hacia la selva invisible (2015), de Pedro Favaron, contribuyen a la conformación de un corpus cada vez más emergente de obras de ficción en las que la ayahuasca ocupa un lugar protagónico como tema y como elemento de experimentación narrativa. En la novela de Calvo analizo cómo la obra integra el conocimiento indígena y las visiones inducidas por la ayahuasca para transformar el relato en una experiencia literaria innovadora que redefine los límites entre lo real y lo visionario. En la novela de Favaron hago énfasis especial en cómo el sentido de la obra y la experiencia transformadora vivida por el personaje principal están orientados por la ayahuasca y por los modos de pensar-sentir-curar según lo expresa la medicina tradicional shipibo-konibo.

KEBIJAKAN FORMULASI TINDAK PIDANA KORUPSI PADA KORPORASI BADAN USAHA MILIK NEGARA BERDASAR KEADILAN PANCASILA
Authors: Helmi Muhammad Ishar
Published: January 2025

Pemberlakuan Undang-Undang Perseroan Terbatas menimbulkan konflik norma. Berlakuanya undang-undang tersebut memberikan pengakuan kekayaan negara yang dipisahkan termasuk dalam salah satu ruang lingkup keuangan negara menjadikan setiap kerugian yang terjadi pada BUMN diklasifikasikan sebagai kerugian negara sehingga direksi dimintakan pertanggungjawabannya secara pidana atas tindak pidana korupsi. Kerugian yang dialami oleh BUMN tidak hanya disebabkan karena adanya penyalahgunaan wewenang semata, tetapi juga sangat dimungkinkan terjadinya akibat dari risiko bisnis. Polemik yang muncul dan menunjukan kerancuan atas pengaturan keuangan negara dan pengaturan mengenai perseroan terbatas secara spesifik memunculkan perdebatan yang berujung pada pertanyaan apakah kerugian bisnis yang dialami BUMN termasuk sebagai kerugina negara ataukah sebaliknya. Tulisan ini menggunakan jenis penelitian hukum normatif dengan pendekatan perundang-undangan dan pendekatan konseptual. Hasil penelitian menjelaskan bahwa kerugian BUMN dapat dikategorikan sebagai kerugian negara mengingat status dan kedudukan BUMN yang memiliki sendi-sendi hukum publik dan kewajiban pengawasan oleh Pemerintah terhadap penyelenggaraan BUMN. Oleh karena itu, Tindak Pidana Korupsi BUMN menjadi bagian dari jenis korupsi kerugian keuangan negara sebagaimana dimaksud UU Tipikor.
Pletivo života: Teologicko-misiologické implikácie jednej metafory
Authors: Bargár Pavol
Published: January 2025

One of the major insights drawn from anthropological research is the acknowledgment that every human being is in each stage of their life embedded in a complex and multi-layered structure of relationships with other people as well as the world around them. Furthermore, theologically rooted anthropologies accentuate yet another type of relationship, namely, one between a human being and the transcendent reality that has in Christian tradition been referred to as God. Following from this fundamental point of departure this article seeks to explore two main questions. First, in which ways can one theologically-missiologically reflect on human existence? And second, what theological-missiological implications does such reflection have? The article proposes the metaphor of a web of life as one possible image that has the potential to inform and orientate such exploration.
Numerical simulation of R134a evaporation in a cold water production system
Authors: Frikha Sobhi , Baccar Mounir
Published: January 2025

In this paper, we introduce a numerical model designed to analyze the evaporation process of R134a refrigerant within a cold water production system. Using the ANSYS Fluent CFD software, our simulation solves the Navier–Stokes equation, thus offering insights into the system’s flow dynamics. Our investigation underscores the efficacy of CFD as a reliable tool for modeling and forecasting flow behaviors within complex systems. Specifically, we delved into the impact of varying the empirical coefficient in the Lee model. Our results indicate that augmenting the coefficient value amplifies the R134a flow rate at the evaporator outlet. Notably, a coefficient value of 0.25 closely matches the experimental flow rate. Furthermore, we analyzed the ascending velocity of R134a vapor, achieving a robust agreement between our numerical simulations and experimental observations. This study underscores the potential of numerical modeling in enhancing our understanding and prediction of refrigerant evaporation dynamics within cooling systems.
Flow-induced fiber orientation in gas-powered projectile-assisted injection molded parts
Authors: Zhang Wei , Wu Jun-wei , Kuang Tang-Qing , Liu He-Sheng
Published: January 2025

A preliminary and groundbreaking study on the fiber orientation pattern in gas-powered projectile-assisted injection molding (G-PAIM) part of short-glass-fiber-reinforced polypropylene was reported, the results showed that the fiber orientation pattern across the thickness of G-PAIM part was remarkably different from that in the parts molded via gas-assisted injection molding (GAIM) and conventional injection molding (CIM) as reported earlier, and the difference of fiber orientation pattern between G-PAIM, GAIM, and CIM parts was mainly due to the unique flow fields generated by projectile penetration. Additionally, fiber orientation states within the G-PAIM part depended not only on their positions both across the part thickness and along the flow direction, but also on the processing parameters. Particularly along the thickness direction, fiber orientation states changed significantly. The results also showed that gas injection delay time was the main factor affecting the fiber orientation states within the G-PAIM part, and a shorter gas injection delay time could remarkably induce more ordered fiber orientation along the melt direction. Within the range of the investigated processing parameter values, a larger ordered region, where most fibers tended to be orderly oriented along the melt flow direction, could be obtained under a larger gas pressure (8 MPa), higher melt temperature (250°C), and shorter gas injection delay time (1 s). This work provides a comprehensive guidance for the fabrication practice of G-PAIM parts of short fiber-reinforced thermoplastics.

Published: January 2025

This study aimed to obtain angiotensin converting enzyme (ACE) inhibitory peptides from barley hordein, a protein rich in proline and glutamine, and to identify novel inhibitors. Hordein was hydrolyzed using four enzymes: pepsin, trypsin, papain, and orientase, an enzyme from Aspergillus oryzae known to cleave the C-terminal side of proline residues. The hydrolysate from orientase showed strong ACE inhibitory activity. LC-MS/MS analysis identified 35 peptides, including 23 derived from hordein and 9 known ACE inhibitors. After synthesizing 15 peptides, 7 showed significant ACE inhibition, all containing proline at the C-terminus. Notably, QQP, a new peptide, exhibited notable activity (IC50 40 μM). The results suggest that barley hordein is a valuable source of ACE inhibitory peptides, with QQP as a promising candidate.
On sup- and inf-attaining functionals
Authors: García-Pacheco Francisco Javier
Published: January 2025

Reflexivity is characterized by the weak-compactness of the unit ball. The weak-compactness of bounded, closed, and convex sets is characterized through sup-attaining functionals in view of the famous James’ theorem. The aim of this mathematical note is to provide the construction of bounded, closed, and convex subsets for which there exists a functional attaining its supremum on such a set but not its infimum. This construction leads to a characterization of reflexivity in the category of normed spaces and a characterization of full norm-attainment also in the category of normed spaces.
A semiotic analysis of the canonical image macro meme
Authors: Paek Jemma
Published: January 2025

This article proposes a semiotic reading of the most widely recognized internet image macro memes (termed “canonical image macro memes” or CIMMs) and analyzes these memes as individual texts. It demonstrates that memes possess their own language, or system of signs, and form their own literature. By delineating the extent to which the visual and verbal components are customizeable image macro memes, this article strives to understand the language of CIMMs, and the processes and limitations by which meaning is generated. Understanding each meme as a text, this analysis demonstrates that the first-order semiological system of memes is informed and underpinned by a discrete, highly specific second-order semiological system, which guides the way in which a meme user will read memetic texts both individually and in relation to one another, and which must be analyzed as a phenomenon unto itself. The increasingly complex interreferentiality found within the growing corpus of memetic texts engenders sets of memes which only acquire signification when read together; a consideration of such memes demonstrates the codification of a metalanguage, or mythology, of memes, which allows us to understand better how memes have begun to consolidate their own canon.
Actitudes lingüísticas en la prensa local y regional del siglo XIX
Authors: Puche Lorenzo Miguel Ángel
Published: January 2025

The importance of the press in the 19th century has been analysed from a variety of perspectives and is of great interest for a better understanding of the diachrony of Spanish, as it relates to a relatively recent period that has been neglected until a few years ago. But it also provides interesting data on the attitudes of speakers towards the most varied issues of linguistic change or, even, on the evolution of the discipline. For this reason, the aim of this paper is to approach the nineteenth-century press in the region of Murcia and to find out what attitudes it had towards language, whether the progress of the discipline was reflected in its pages or how it was perceived in terms of the uses attributed to the geolectal variety. In this way, it will be possible to check whether the smallest and least geographically widespread newspaper showed interest in the current linguistic uses and, consequently, whether any kind of debate was established in this respect. The main interest is to relate the results to one of the most unknown peripheries of Spanish.
Actitudes lingüísticas negativas en el Diccionario de Autoridades (1726–1739)
Authors: Buzek Ivo
Published: January 2025

Dictionaries are lexical corpora that reflect the socio-cultural reality and power relations at the time of their publication. They provide information on how to use words and at the same time contain statements about individuals, ethnic groups or social classes who are supposed to use them. These kinds of judgments are known in sociolinguistics as linguistic attitudes, and dictionaries are a legitimate source for studying them, capable of providing new data and innovative methodological approaches. This paper studies linguistic attitudes in the Diccionario de Autoridades (1726–1739), which has not yet been analysed by our discipline. We will focus on negative attitudes represented by terms identified as “low social class”, “plebeian”, or “vulgar”. We will be interested in whether they refer to idiomatic registers, social classes or regional varieties of Spanish, and we will pay attention to the texts that refer to them. In the case of definitions without textual documentation, we will focus on patterns that may have influenced the lexicographers’ decisions and whether they may have been politically or ideologically motivated. As mentioned above, this work is a pioneering sociolinguistic study in the field of the Real Academia Española lexicography.
Una re-visión de los diccionarios ortográficos. El caso del Diccionario ortográfico (1906) de Serafín Ledesma: oralidad y escritura en una obra lexicográfica uruguaya olvidada
Authors: Sancha Vázquez Julián
Published: January 2025

Within the field of Hispanic lexicography, there is still a significant —and largely unnoticed— gap in the historiographical study of a specific type of dictionary. We are referring to the so-called “orthographic dictionaries”, which flourished in the nineteenth century, but gradually disappeared (or transformed) during the twentieth century and have survived to the present day as a remnant that has been incorporated into doubt dictionaries. Telling their story may require an analysis that has not (at least partially) been carried out in historiographical works. In addition, we have carried out an in-depth study of a previously unstudied dictionary that has not yet been included in lexicography, the Diccionario ortográfico. Parónimos y vocablos semejantes compilados y ordenados. This work was published in Montevideo in 1906 by a Uruguayan justice of the peace, Serafín Ledesma. The importance of rescuing this work from oblivion lies in the potential impact it could have had, as we could have just discovered one of the most ambitious and comprehensive dictionaries in its category.
Les unités de mesure impériales et métriques en français québécois (une livre de beurre, un litre de lait, trois pieds de haut, cent mètres d’ici) : un système mixte qui fait du millage
Authors: Dostie Gaétane
Published: January 2025

This paper provides an overview of the lexical changes that have occurred since 1970 in the paradigm of lexemes referring to measurement in Québec French spoken in informal and semi-formal contexts. The study is based on an exhaustive inventory of lexical units, specific to the British Imperial System or English System (ES ; e.g., pouce ‘inch’, livre ‘pound’) and the Metric or International System (IS ; e.g., mètre ‘metre’, kilo(gramme) ‘kilogram’), present in 7 oral corpora, of which the recordings were made between 1970 and 2020. In addition, a survey was carried out in spring 2023 with 12 speakers to determine their use of ES or IS in various everyday situations. It is generally thought that older speakers are partly responsible for the remarkable preservation of a small group of imperial units in Québec French. The data collected in the corpora and in the survey show that this perception is at odds with reality. The paper points out that there are referential contexts in which speakers, regardless of their age, are naturally inclined to use imperial units, and other contexts in which they are led to opt for metric units.
More than PHB – the PHAmily of Copolymers: Justifications for Broader Use and Summary of Biodegradation Facts on Polyhydroxyalkanoates (PHA) – A Review
Authors: Lackner Maximilian , Costa Paolo , Koller Martin , Zinn Manfred
Published: January 2025

Globally, a significant portion of plastics are mismanaged, ultimately ending up in

the environment. While reducing, reusing, and recycling plastics should be the preferred

end-of-life scenarios, biodegradable plastics are compatible with all of these routes and

represent a promising alternative. Polyhydroxyalkanoates (PHAs), a family of polyesters

synthesized by various microorganisms, stand out in this regard. The most common type

of PHA, poly(3-hydroxybutyrate) (PHB), is particularly relevant as it is both biobased

and biodegradable. Additionally, there is substantial knowledge about this thermoplastic

polyester, its applications, and its commercial availability. However, over 150 other PHA

building blocks have been identified, with some having been tested and developed for

various promising applications. Despite this, not all PHA copolymers have been fully

evaluated for their biodegradability across diverse environmental conditions. Nevertheless, due to their biosynthesis in living microorganisms, a good degree of biodegradability is expected. Moreover, PHAs can also be chemically recycled into valuable chemicals, positioning them as the biobased polymer with the most versatile end-of-life options.

This review summarizes the current state of knowledge on PHA copolymers, their cur

rent end-of-life pathways, the most relevant biodegradability standards, and their degradability by depolymerase enzymes.
Pyrolysis of Golden Snail Shells (Pomacea canaliculata L.) for Phosphorus Removal from Aqueous Solutions
Authors: Vu M. T. , Hoang Le-Thuy-Thuy-Trang , Dao Minh-Trung
Published: January 2025

Biochar derived from abundant waste biomass has emerged as an eco-friendly alternative to conventional adsorbents. In this study, biochar produced from golden snail shells through a simple pyrolysis process was applied for phosphorus adsorption. The effects of pyrolysis temperature and time on adsorption capacity were investigated. The biochar pyrolyzed at 800 °C for 90 min (B800) exhibited the best adsorption performance. Optimal adsorption conditions were determined to be a pH of 4.0 and an adsorbent dose of 1.6 g L–1. The adsorption of phosphorus onto B800 could be well described by the Langmuir model and the pseudo-first-order model, achieving a maximum adsorption capacity of 63.5 mg g–1 and a rate constant of 0.029 min–1. This study highlights the potential of biochar derived from agricultural waste as a highly efficient and environmentally friendly adsorbent for phosphorus removal. Furthermore, the adsorption mechanism, driven by the electrostatic interaction occurring prior to Ca-P precipitation, was elucidated. The phosphorus adsorbed onto biochar can potentially be recycled as a soil fertilizer.
Hunger spread and issues in government agricultural sector financial policies: Analysis of food security financing in Nigeria
Authors: Adeforiti Rotimi , Onikanni Tobiloba Emmanuel
Published: January 2025

Although food security remains a problem in sub-Saharan Africa, studies have not assessed how food security financing propels food insecurity in Nigeria. The study analyses food security financing in Nigeria, explains the implications of finance accessibility for food supply in the country, and describes the challenges confronting food security financing in the country. The Public Interest Theory was adopted for the study from the perspective that whilst common goals are absent, different individuals pursue their goals separately, and this manifests as the profit-making objective of farmers or food suppliers. The study adopted an integrative literature review method to purposively select a total of 20 peer-reviewed journal articles published between the years 2018 and 2023. Data were collected through content analyses and thematically presented. The study revealed that food security is financed by individual farmers following poor funding from the government. The sources of funds available to individuals are both formal and informal. The implication of access to finance by those in the agricultural sector including farmers has been identified to include an increase in food supply. The challenges confronting food security have been identified to include profit motives by producers inducing inflation, climate change, poor electricity supply, insecurity, and inadequate finance. The study submitted that finance is key to attaining food security in Nigeria.
A review on governance principles of cross-border Central Bank digital currency interoperability: A case study of Project Dunbar
Authors: Annathurai Anusha , Abdul Wahab Norwazli , Jamil Nurul Syafidah
Published: January 2025

Cross-border central bank digital currency (CBDC) interoperability projects involving multiple CBDC (mCBDC) initiatives through collaboration among central banks have increased due to fintech innovation. In response to the governance concerns raised by Project Dunbar, one of the pilot initiatives, this study attempted to assess its compliance with the principles of cross-border Central Bank Digital Currency (CBDC) interoperable governance. Despite the study's reliance on grey literature, the interoperable governance enhancements that Project Dunbar requires were highlighted based on the following principles: (1) transparency and accountability, (2) oversight authorities, (3) user accessibility and inclusion and (4) inter-jurisdictional cooperation. The study proposes further studies on the development of implementation strategies and review of other initiatives as case studies.
Instytucje państwa a zawodność państwa – czy istnieje relacja przyczynowo-skutkowa?
Authors:   Uniwersytet Ekonomiczny w Poznaniu, Totleben Bartosz
Published: January 2025

Purpose – The main aim of this article is to identify, based on economic theory, the causal relationship between state institutions and government failure. The specific objectives include the conceptualization of government failure and state institutions. Research method – The article compares two main methods of identifying causal relationships: those based on quantitative methods and those demonstrating mechanisms (a mechanistic approach) without empirical evidence. Due to the theoretical nature of the article, the second approach is employed. Results – The combined operation of extractive political institutions and extractive economic institutions increases the risk of state failure, primarily due to the strengthening of interest groups and the phenomenon of rent‑seeking. Inclusive institutions reduce this risk. Originality / value / implications / recommendations – State institutions, due to the potential occurrence of the “vicious circle” and the “virtuous circle,” are crucial in limiting government failure. Enabling citizen participation in political processes, democratic control, and limitation of power, as well as ensuring equal access to markets, promote faster growth and economic development in the long term.

Authors:   Uniwersytet w Białymstoku, Karpińska Kinga , Owczarczuk Magdalena ,   Uniwersytet w Białymstoku
Published: January 2025

Purpose – Based on the analysis of available statistical data and literature, hypothesis was adopted that an increase in the rate of technological change and the level of digitalization of the Polish economy is conditioned by an increase in enterprises’ investment in employee competencies. In this context, the main objective of the article and the conducted research was to verify whether and to what extent enterprises in Poland invest in training their employees. Research method – The article employs methods of logical reasoning (deduction and induction) as well as data processing methods, such as analysis and synthesis. In the empirical part of the article, a survey conducted between November 2023 and April 2024 among 421 enterprises operating in Poland was utilized. Results – An analysis of the literature and survey data has revealed that investments in employee training are a significant determinant of technological change, including in Polish enterprises. It can be observed that the larger the enterprise, the more intensive and diverse the training activities undertaken. Micro and small enterprises primarily invest in developing hard skills, which stem from the need to address competency gaps. On the other hand, medium and large companies offer their employees a more diverse range of training, both in terms of enhancing hard skills and soft skills. Originality / value / implications / recommendations – The analyses and considerations presented in this article have filled a research gap by demonstrating the role of training as a determinant of technological change in Poland. Furthermore, the conducted research has revealed new research problems. A notable lower participation in soft skills development training can be observed, resulting from employers’ concerns about their effectiveness.

Authors:   University of Economics in Katowice, Hanus Gabriela
Published: January 2025

Purpose – This article aims to identify, analyze, and characterize consumer attitudes to chatbots in logistics customer service and the factors determining these attitudes. Research method – The empirical study on the attitudes of Polish consumers to the use of chatbots in logistics consumer service was conducted on a research sample of 553 consumers in March 2024 and covered the entire area of Poland. Results – The study suggests that most respondents are open to using chatbots in logistics customer service, seeing them as useful for improving service speed and effi ciency. They mainly use chatbots occasionally on websites and phone lines, preferring their text-based versions for tracking shipments and receiving technical support. The key positive factors include 24/7 availability and quick responses. Concerns involve the misinterpretation of questions, incorrect responses, a lack of human support, and limited functionality. Non-users often mention a lack of opportunity to try chatbots and a prefe rence for human interaction. Originality /value /implications /recommendations – The research subject is unique, rarely studied in Polish literature, even though up-to-date knowledge of consumer atti tudes to the use of chatbots in logistics consumer service is particularly important for business strategies.
Skutki procesu dekarbonizacji dla gmin województwa śląskiego w zakresie dochodów z opłaty eksploatacyjnej
Authors:   Uniwersytet Ekonomiczny w Katowicach, Sygut Edyta
Published: January 2025

Purpose – Withdrawal from hard coal as an energy source, and the resulting abandonment of its extraction, has numerous consequences, including fiscal ones. The purpose of the article is to assess the effects of decarbonisation process on the financial management of municipalities of the Silesian Voivodeship in terms of mining fee in the context of fiscal stability. Research method – The research covers the period of 2012–2022. The first stage consists in the assessment of the fiscal efficiency of mining fee in the budgets of municipalities of specific voivodeships in Poland, separately in terms of the receipts classified in sections 046 and 051. The research at the second stage was focused on receipts from mining fee in the budgets of municipalities of the Silesian Voivodeship. Results – The Silesian Voivodeship has the highest mining fee revenue from hard coal mining companies. Decarbonisation process results in declining revenue from hard coal mining companies in the municipalities where hard coal extraction is carried out. The cessation of hard coal mining means the loss of efficient source of revenue, which will result in the destabilisation of their financial management. Originality / value / implications / recommendations – The financing of municipalities in Poland requires a change, because as a result of decarbonisation, the municipalities in mining regions will be completely deprived of mining fee revenue, while at the same time their “post‑mining” expenditures will increase.

Bases históricas e permeio da contabilidade patrimonialista no Brasil entre os anos 50 e 80 e os seus efeitos doutrinários de maturidade científica
Authors: Chaves da Silva Rodrigo Antonio
Published: January 2025

O objetivo de nosso artigo é tratar basicamente sobre a escola brasileira de contabilidade entre o meio do século XX ao período próximo do seu final, principalmente no que tange aos sucessos da escola patrimonialista, sua maturidade doutrinária, personalidade científica, e efeitos em forma de corrente de pensamento. O objeto é o estudo da história do conhecimento contábil brasileiro e a problemática de sua evolução, focando no aspecto patrimonialista que predominou e que predomina até os dias de hoje. Como não foi feito trabalho semelhante sobre a história de desse conhecimento, este artigo aprofunda brevemente o problema levantado dessa cronologia nacional procurando evidenciar o estado científico, e seu possível desenvolvimento. Este empreendimento se embasa na hipótese de que os trabalhos de doutrina patrimonialista no Brasil foram melhores desenvolvidos nas décadas de 50 e 80, como bases extremas para uma escola filosófica de contabilidade, ou até a maturidade de uma doutrina nova, hoje conhecida como neopatrimonialismo. Os métodos utilizados são os históricos que se embasam na crítica, igualmente, por meios documentais e bibliográficos, além dos provindos da hermenêutica, de maneira a vir a explicar o fenômeno histórico-gnosiológico de nosso conhecimento.

Published: January 2025

The article discusses the application of food irradiation as a solution for food preservation and safety in naval settings, focusing on the missions of the Brazilian Navy's submarines. Food irradiation, recognized in 37 countries, effectively eliminates parasites, fungi, and bacteria, extending the shelf life of foods without compromising their nutritional and sensory qualities. The research used an electronic questionnaire to assess the knowledge and acceptance of food irradiation among military and civilian personnel of the Navy. Results indicate that before receiving information, 54% of participants were unaware of the technology, and 28% had a negative view of nuclear energy. After exposure to informative materials, 82% of participants expressed willingness to consume irradiated foods, up from 54% previously. The study highlights the importance of education and scientific dissemination for the acceptance of the technology and suggests expanding the study to a larger sample within the Navy. The findings suggest the potential use of food irradiation in Navy ships and submarines, contributing to the health and well-being of crew members.

This study investigates the electrostatic field in a discharge chamber (DC) designed for water purification from organic pollutants using pulsed barrier discharge (PBD) technology. The DC consists of vertical plane-parallel electrodes, with an air gap containing water droplets between them, and one of the electrodes is insulated from the air gap by a dielectric (barrier). The research employs computer modeling in both two-dimensional and three-dimensional setups. Therefore, the aim of this work is to compare the distribution of the electrostatic field intensity of PBD in the air gap and the electrical capacitance of the DC to establish the optimal distance between droplets and to determine the calculation error using the two-dimensional DC model. Electrostatic field modeling was performed using the Poisson equation and the finite element method. Calculations were performed for two-dimensional and three-dimensional models with conditions of a droplet diameter of 1 mm, a gas gap length of 3.36 mm, and an applied voltage of 3 kV. The influence of droplet conductivity and the distance between them on the characteristics of the electrostatic field in the gas medium and in the droplets was investigated. A comparison of the calculated capacitance values of the DC in the two-dimensional and three-dimensional models depending on the distance between the droplets was conducted. The research results can be used in the application of electro-discharge technology based on pulsed barrier discharges in water treatment systems, specifically in selecting the parameters for the movement of the treated liquid in the plasma zone.

Requirements for semiconductor power converters with a high level of load current have been formulated. A review of research works addressing the problem of achieving maximum efficiency in DC voltage regulators using synchronous rectifiers based on modern field-effect transistors has been conducted. The proposed methods of synchronous rectification in pulse DC voltage stabilizers utilizing high-frequency magnetic amplifiers are described. These methods rely on the use of existing signals within the converter and eliminate the need for additional components or specialized drivers in their circuitry. The principle of operation is explained, and theoretical oscillograms are provided, which are validated by experimental data. Experimental results on the efficiency of such converters are presented. Specifically, the proposed methods of synchronous rectification in a pulse DC voltage stabilizer based on high-frequency magnetic amplifiers, with an output power of 300–400 W and input DC voltage of 310 V (equivalent to an industrial-frequency network), achieved an efficiency of 95%.

In the article the reactive power of an asynchronous machine (AM) in a stable mode is obtained as a function of three vari-ables: the angular speed of rotation of the AM shaft, the module of the rotor flux coupling and the moment of static load on the shaft. The AM power factor decreases in electric drives (ED) of industrial mechanisms in which the load moment while maintaining its direction of action can take a static value less than the nominal value. Therefore, in order to ensure a high power factor of an asynchronous ED in long-term operating modes with a variable load, a vector AM control system was created, in which the magnitude of the rotor flux coupling is regulated by the reactive power channel as a function of the mo-ment of static load on the shaft. To identify the moment of loading, as well as the angular speed of the rotor and its flux cou-pling, a Kalman observer is synthesized, which allows creating a vector control system with simultaneous regulation of the speed and power factor of the AM without physical sensors of the reference vector of the rotor flux coupling and its angular speed of rotation. The significant dependence of the extreme values of the rotor flux coupling for reactive power on the torque on the AM shaft and insignificant dependence on the speed has been proved. Stability and high control quality are achieved by simultaneous use of relay control laws, invariant to coordinate and parametric perturbations, and the effectiveness of the Kalman filter algorithm for identifying variable states in the feedback loop. Thus, the article theoretically substantiates the idea of creating a sensorless relay-vector control system for an asynchronous ED with simultaneous speed regulation and optimization of AM energy indicators. The mathematical model is created as a program written in the Matlab programming language. The operability of the proposed asynchronous ED control system was confirmed by the method of mathematical modeling. References 12, figures 6.

The influence of the structure of the electromechanical water supply system of a 12-story building (replacing one riser with two risers of different levels) on the efficiency of energy and water resource use was studied. A mathematical model of the electromechanical system has been developed and implemented in software, which takes into account the dependence of the floor consumption on the pressure value and allows determining the water needs of consumers based on the given cyclorama of the water consumption of the house. According to the information about the known parameters of the basic version of the water supply system, the parameters of one floor and the parameters of the variants of the building system with risers for servicing floors are determined: 1-12; 1-6; 7-12. The study was carried out taking into account the proposed time dependence of the change in the input pressure of the house. Means of generalized determination of the energy efficiency of the asynchronous motor of the water supply system based on approximate dependences of nominal efficiency on power and efficiency on the degree of loading have been developed. The comparison of options was carried out according to the formulated expression of the efficiency criterion, as the ratio of the daily useful effect of the water supply system to consumers to the cost of electricity and water consumed during the given period. According to the simulation results, the two riser option provides savings of 4% of water and 25% of electricity with their ratio in monetary terms 6:1. This justifies the priority of taking into account water savings when justifying the modernization of water supply systems (parallel zoning, adjustable electric drive).
