Published: December 2024

RESUMO Este estudo teve por objetivo sistematizar, na literatura científica nacional e internacional, os conceitos de Fonte Usual de Cuidados (FUC), as abordagens metodológicas utilizadas e os fatores determinantes relacionados com o seu reconhecimento pelos usuários dos serviços de saúde. Trata-se de uma revisão de escopo. A busca foi realizada nas bases de dados Web of Science, Scopus, Science Direct e PubMed, sem restrição de período de publicação e idiomas. Critérios de elegibilidade: estudos originais que respondiam à pergunta de investigação definida previamente e disponíveis nas bases de dados. Foram identificados 632 artigos, dos quais 41 constituíram a amostra final deste estudo. Esta revisão constatou que, ser do sexo feminino, raça/cor branca, maior renda, escolaridade e ter seguro saúde estiveram associados ao reconhecimento de uma FUC. Evidências semelhantes foram observadas para FUC Atenção Primária à Saúde (APS), além de estudos destacarem outros determinantes que demonstram maior vulnerabilidade dos indivíduos. A partir dos fatores determinantes, observaram-se desigualdades no reconhecimento de uma FUC na maioria dos países, variando em relação aos contextos organizacionais dos sistemas de saúde, o qual evidencia que os sistemas universais são favoráveis para o reconhecimento de uma FUC.

Published: December 2024

ABSTRACT The Family Health Strategy is known to minimize the effects of health inequalities. This descriptive study aimed to present the distribution of Family Health teams (eSF) and PHC Units (UBS) in the Federal District (DF) using the Health Vulnerability Index (IVSaúde) and demographic density categorized by census tracts as parameters. We employed data from the most recently published demographic Census and official data from the National Registry of Health Establishments and the DF’s State Health Secretariat. The results revealed that the DF has a heterogeneous population when it comes to vulnerability and that most of the high-risk census tracts are in peripheral areas. The DF has 165 UBS and 615 eSFs (mean: 3.7 teams/UBS). Around 35% of the census tracts have low-risk IVSaúde, and 19.8% have high and extremely high risk. The study showed that most UBS and teams are in high demographic density and more significant vulnerability areas. However, there is still a need to increase the number of teams and UBS for adequate coverage of the model adopted in the federal capital and reduce the ratio of teams per health establishment.

Published: December 2024

RESUMO Embora institucionalizadas no Sistema Único de Saúde, a dinâmica de implementação das Práticas Integrativas e Complementares (Pics) na Estratégia Saúde da Família, pela perspectiva da odontologia, representa um campo inédito de estudo. Assim, buscou-se compreender a percepção dos cirurgiões-dentistas atuantes nesse contexto, no município de Vitória, Espírito Santo, quanto à incorporação e à implementação dessas práticas. Realizaram-se entrevistas semiestruturadas com 40 cirurgiões-dentistas, gravadas, transcritas e submetidas à análise de conteúdo de Bardin. Dos dados, emergiram três categorias: o entendimento sobre Pics, a percepção sobre incorporação e implementação, e sobre as políticas de Pics. Observaram-se a compreensão, a aceitação e o interesse unânimes das práticas, evidenciando seu valor alinhado às diretrizes das políticas relacionadas, realçando o significativo potencial disponível no município. No entanto, desafios como lacunas de conhecimento das políticas e das regulamentações odontológicas específicas, bem como falhas no processo de educação permanente, destacam a importância de aprimoramento das estratégias de divulgação e capacitação dos profissionais. Conclui-se que, embora estejam incorporadas e haja um potencial considerável para expansão, é necessário ultrapassar as barreiras que se apresentam, a fim de alcançar uma implementação efetiva das Pics no município, incluindo em contextos específicos como a odontologia.

Ceramic composite materials based on the MAX phase Ti3SiC2 obtained by SHS extrusion
Authors: Konstaninov А. S. , Chizhikov А. P. , Antipov М. S.
Published: December 2024

Compact cylindrical rods 220 mm long and 4 mm in diameter, consisting of a ceramic composite material based on the MAX phase Ti3SiC2, strengthened by TiC and TiB2 particles, were obtained during the combustion of the initial components (titanium, silicon, soot and boron) in the SHS mode followed by high-temperature deformation. These conditions were implemented in the SHS extrusion method. The influence of the initial composition on the structure, phase composition and mechanical characteristics (nanohardness, elastic modulus, bending strength) of the resulting materials has been established. It has been established that the formation of the Ti3SiC2 MAX phase occurs at the boundary with the TiC phase due to the diffusion of silicon under the influence of high temperatures (up to 1980‒2125 °C) accompanying the SHS extrusion process.

Çalışmada son kırk üç yıl içinde Afganistan’dan Türkiye’ye göç etmiş Afgan (Özbek) göçmenlerin dinî algıları, yaşayış ve davranışlarıyla birlikte sosyokültürel açıdan değişimleri araştırılmıştır. Araştırma nitel bir desene sahip olup araştırmada mülakat tekniği kullanılmıştır. Farklı illerden on katılımcıyla görüşme yapılmıştır. Katılımcılar, Türkiye’ye savaş, yaşam kaygısı ve evlilik gibi nedenlerle göç etmiştir. Türkiye’yi seçmiş olmalarındaki etken, Müslüman kimlikleri ve etnik köken olarak kendilerini Türkiye’ye yakın görmeleridir. Katılımcılara Türkiye’ye uyum ve memnuniyet, memleket özlemi, geleceğe ilişkin beklenti, hayat standardı, göç sürecindeki zorluklar, gelenek ve kültürleri, komşulukları, sosyal ve manevi destek, çok eşlilik ve bağımlılıkla ilgili sorular sorularak kültürel değişime; din eğitimi, dinî hayat ve dinî başa çıkma ile ilgili sorular sorularak da dinsel değişime yönelik veri elde edilmeye çalışılmıştır. Araştırmada göçmenlerin Türkiye’den memnun oldukları, ülkelerine geri dönmeyi düşünmedikleri bulgulanmıştır. Ancak göçmenler, her ne kadar Türkiye’ye uyum sağlamış gibi görünseler de kendi etnik gruplarıyla alt kültür oluşturdukları ve entegrasyon stratejisini seçtikleri söylenebilir.
Ontologías políticas plurales en los procesos de transición sostenible
Authors: Zurbriggen Cristina , Gioscia Laura
Published: December 2024

A pesar de las advertencias científicas sobre las problemáticas ambientales, hasta la fecha se han identificado pocos avances orientados hacia una transición sostenible. En este escenario, el objetivo de este trabajo es reflexionar sobre la relevancia de abordar la dimensión política y los conflictos ontológicos en el estudio de las transiciones hacia la sostenibilidad. Considerar las ontologías políticas permite una mayor apertura y comprensión de perspectivas diversas. Esto implica reconocer que hay diferentes realidades y maneras de ver el mundo, y que no existe una única solución para todos los problemas ambientales. Al hacerlo, se abre la posibilidad de avanzar hacia ontologías múltiples y promover una transición sostenible más inclusiva, equitativa y adaptada a la diversidad de realidades y perspectivas presentes en nuestro mundo. Con el fin de aportar a estos debates, en el presente artículo se propone una reflexión crítica sobre la importancia de considerar las ontologías políticas en el abordaje de problemas socioambientales complejos. Para ello, examinamos las ontologías políticas y el creciente interés académico por incorporar la dimensión ontológica en los estudios ambientales y los aportes relevantes realizados desde América Latina. A continuación, reflexionamos sobre la relevancia de valorar el disenso en las transiciones sostenibles, incorporando el pluralismo ambiental en procesos de cambio.

Published: December 2024

Para facilitar una transición de la agricultura industrial es imperativo fortalecer los vínculos entre la política y la agroecología. Esta última no debe entenderse solo como el resultado de una serie de propiedades físicas y biológicas, ya que también refleja relaciones socioculturales de poder. Por lo tanto, para promover una transición agroecológica se requiere de la acción individual y colectiva, la cual se da cuando los actores se articulan en una visión común. A partir de la hipótesis “sin acción colectiva no hay transiciones agroecológicas”, en el presente artículo analizamos el funcionamiento social, ambiental y productivo en los territorios comunales Chigani Alto, Villa Anta y Cebollullo en tres comunidades Aymaras. Nuestra perspectiva teórico-metodológica se basa en el marco de las transiciones agroecológicas del Instituto de Agroecología de la Universidad de Vermont, junto con el enfoque de investigación-acción participativa.
Resistencia y emancipación desde los oficios textiles. Un análisis desde las teorías del poder
Authors: Bejarano-Rubio Daniela
Published: December 2024

Con base en las diversas teorías del poder busqué comprender la capacidad de resistencia y emancipación que subyace en el quehacer textil. Ubiqué el poder en la colectividad que surge en los espacios de encuentro y construcción alrededor de estos oficios en el contexto del Paro Nacional colombiano de 2021. Realicé un estudio sobre casos y espacios colectivos de enseñanza e intervención textil para mostrar la forma en que estos espacios brindan una nueva forma de entender y valorar el poder. Se devela cómo los oficios textiles permiten una expresión del poder a través de la colectividad, al ocupar el espacio público que alguna vez fue despojado a las mujeres, se devela el remiendo como ruptura de categorías y comportamientos impuestos que resignifica el quehacer textil y reta las escisiones modernas.

Indicadores de programas de políticas públicas: una revisión del programa Ciudades Seguras en Quito
Authors: Robledo Maria Susana
Published: December 2024

Entre 2013 y 2018 en Quito se implementó el programa Ciudades Seguras y Espacios Públicos Seguros, cuyo objetivo fue disminuir el índice de violencia física, sexual y psicológica a las que están expuestas mujeres y niñas en los lugares públicos. Este programa, financiado por ONU Mujeres, integró a diversos actores de la sociedad civil y del Estado, sin embargo, finalizado el plazo establecido el programa llegó a su fin. A partir del análisis de los indicadores de evaluación de impacto, se concluye que, si bien las acciones implementadas fueron exitosas, su limitación temporal, sumada a la escasa integración de colectivos de mujeres locales y a la imposibilidad de convertirse en política de Estado, incidieron poco en los cambios estructurales necesarios para la construcción de un espacio público seguro y accesible para todas las personas, en particular para las mujeres y niñas.

Authors: De Miranda Geralda Luiza
Published: December 2024

O artigo tem como objetivo comparar o nível de solidariedade no financiamento da seguridade social de 20 sistemas latino-americanos. Partindo dos conceitos de solidariedade de Marshall e seguridade de Beveridge e da tese de Esping-Andersen, são investigados e pontuados indicadores relativos à estrutura de financiamento da seguridade, que define seu potencial de desmercantilização; à organização da proteção previdenciária, que estabelece as linhas de estratificação das provisões; e aos limiares de tributação, que podem mitigar ou maximizar o potencial de desmercantilização, compondo o Índice de Solidariedade da Seguridade Social. As informações que subsidiam a análise foram coletadas nos portais da ISSA e Cepal e na normatização. A análise mostra a importância da organização da proteção previdenciária e dos limiares de tributação para mitigar e aumentar o potencial de desmercantilização dos sistemas e a variação do índice na região, destacando-se positivamente os sistemas pioneiros e os regimes de repartição.

Published: December 2024

En Ecuador se ha planteado nuevamente el debate sobre la sostenibilidad del sistema de pensiones. En la mayoría de países de América Latina se han realizado reformas; unas se basan en el cambio del modelo de ahorro y el reparto con beneficios; otras, en el de capitalización individual hacia un sistema mixto multipilares; y algunas reformas son de tipo paramétrico dentro de sus propios esquemas de pensiones. Ecuador se enfrenta a un doble problema: uno que afecta a la cobertura del sistema de pensiones y otro que trata de afrontar la reforma sobre la sostenibilidad del seguro de invalidez, vejez y muerte. Países como Uruguay y Costa Rica ya atravesaron estas discusiones y en la actualidad afrontan nuevos desafíos de los cuales se desagregan estas experiencias que pueden servir para alimentar el debate que se encuentra instalado en Ecuador.

Hacia una interculturalidad resurgente: generando hermandad, grietas decoloniales y sanación en la Amazonía ecuatoriana
Authors: Reichert Alexandra , Salazar Shiguango Ofelia
Published: December 2024

En el artículo examinamos un intercambio de conocimientos medicinales entre mujeres waoranis y kichwas en la Amazonía ecuatoriana. Utilizando la interculturalidad crítica y el internacionalismo indígena, proponemos el concepto de interculturalidad resurgente como un nuevo modelo para estudiar la salud intercultural y con el que se descentraliza la perspectiva occidental y se ponen los pensamientos indígenas en el centro del debate. Nos enfocamos específicamente en un evento desarrollado en la provincia Napo en el que participaron once mujeres kichwas de la Asociación de Mujeres Parteras Kichwas de Alto Napo y siete mujeres waoranis. En contraste con otras formas de interculturalidad que buscan encajar las perspectivas indígenas en marcos occidentales, describimos de qué forma este tipo de intercambio demuestra el poder de la colaboración en materia de salud entre comunidades indígenas fuera de los espacios de salud biomédicos. Este artículo tiene implicaciones más amplias para la salud pública, pues llevamos la conversación más allá del hospital y hacia las comunidades indígenas. También es relevante para los estudios indígenas de manera más amplia, al revelar hallazgos significativos en las áreas de atención de salud reproductiva, prácticas de sanación y estrategias de resiliencia. Con este texto se proponen algunas bases para una interculturalidad que va más allá de los silos biomédicos y ancestrales, y destaca la colaboración entre diferentes grupos indígenas.

Introduction. Development of the manufacturing industry has led to the emergence of new methods for manufacturing blanks and parts. One of these new promising methods is additive manufacturing and, in particular, electric arc and electron beam surfacing technologies. The use of these technologies in the production of blanks from heat-resistant materials provides a number of significant advantages. The paper presents the results of a study of the microstructure of Inconel 625 specimens obtained using EBAM and WAAM technologies. The purpose of the work is a comparative analysis of the microstructure of Inconel 625 nickel alloy blanks obtained using EBAM and WAAM technologies. Methods and materials. The paper examined specimens obtained using EBAM and WAAM technologies. The specimens were manufactured using equipment developed at Tomsk Polytechnic University. Metallographic studies, scanning electron microscopy were carried out, and the microhardness of the obtained specimens was determined. Results and discussion. Comparison of specimens obtained by two different additive printing technologies EBAM and WAAM showed general patterns of structure formation that appear when using additive technologies. The specimens have a dendritic microstructure and contain zones rich in Ti, Mo and Nb, which is typical for nonequilibrium cooling. Pores are also observed in the specimens. The grains in the specimens have a predominantly elongated shape and are oriented in the direction of heat removal. The length of the grains reaches 1 mm. Differences in the specimens are observed in the number of formed inclusions of intermetallic compounds, in the number of formed pores, in the size of the grains. The EBAM technology provides more uniform structure. The difference in hardness between EBAM and WAAM is about 3.5 %. At the same time, the speed of specimen production using the WAAM technology is significantly higher.

Introduction. Vegetable-based hybrid nanofluids are increasingly important in the context of Minimum Quantity Lubrication (MQL) turning due to its enhanced lubrication properties and environmental benefits. These nanofluids, which typically combine vegetable oils with nanoparticles like graphite or titanium dioxide, improve machining performance by reducing friction and cutting forces, leading to better surface finish and tool life. The purpose of the work. Coated carbide tools are widely used for machining SS 304 stainless steel due to its wear resistance and high temperature resistance. The purpose of the current work is to evaluate the machining performance of SS 304 steel under different concentrations of hybrid nanofluids. The methods of investigation. In this study, an attempt was made to use copper oxide/aluminum oxide (CuO/Al2O3) hybrid nanoparticles mixed with corn oil. A total of six hybrid cutting fluids with 100 ml volume and different mass concentration (0.4 %, 0.8 %, 1.2 %, 1.6 %, 2 %, and 2.4 %) were developed and its performance on SS 304 steel was investigated. Results and discussion. The finding revealed that with an increase in the mass concentration, the thermophysical properties improve. In addition, it is shown that friction decreases with an increase in the particle concentration to 1.6 wt. %. At a concentration of 1.6 wt. % of CuO/Al2O3 hybrid cutting nanofluid showed the best performance characteristics. This study also provides a comparison with dry turning. The highest tool wear was observed in dry turning, followed by turning using corn oil. A 32 % reduction in cutting force is observed. The surface roughness when using CuO/Al2O3 hybrid cutting nanofluid is reduced by 27.7 %. However, when using a hybrid nanofluid (2.4 % of CuO/Al2O3), low tool wear is observed. In this study, the possibility of using vegetable-based hybrid nanofluids for metal turning with a minimum amount of lubricant is considered.
Systematics of multi-tool setup on lathe group machines
Authors:   Azerbaijan Technical University, Baku, Yusubov Nizami , Abbasova Heyran ,   Azerbaijan Technical University, Baku
Published: December 2024

Introduction. The analysis of factory lathe-automatic operations revealed a significant variety of multi-tool setups and identified its areas of application. To develop a matrix theory of accuracy for multi-tool machining and create a unified algorithmic approach to errors modeling for all possible spatial multi-tool setups, it is necessary to consider the flexibility of the technological system in all coordinate directions. In this regard, it is required to systematize a large number of existing multi-tool setups and classify it to structure the information and improve the understanding of its application. Purpose of the work is to develop a classification of multi-tool setups on multi-carriage and multi-spindle CNC lathes, enabling the creation of both a matrix model of machining accuracy for each classification class and a unified generalized matrix model of machining accuracy for the entire classification class. The work investigates the systematics of multi-tool setups, oriented toward the development of matrix models of machining accuracy. Therefore, the classification considered in this work is aimed at identifying the characteristics of force loading and deformation of the technological system during multi-tool machining. The research methods involve identifying the parameters used for classification and the hierarchy of these parameters, which determines the levels and order of the systematics. Based on the principles of systematics of multi-tool setups used in traditional automatic lathes, an analysis of its adaptation to the capabilities of modern lathes designed for multi-tool machining is conducted. Results and discussion. As a result of the research, a formalized six-level classification of multi-tool setups is developed, which includes the following aspects: the method of workpiece mounting, the set of carriages, the types of cutting tools, the types and directions of carriage feeds, the orientation of cutting tools relative to the workpiece, and the method of tool engagement (parallel, sequential). This classification takes into account the technological capabilities for organizing multi-tool machining on modern CNC lathes. The main classes of the proposed systematics of multi-tool setups in the presented work include single-carriage single-coordinate setups, single-carriage two-coordinate setups, dual-carriage single-coordinate setups, dual-carriage two-coordinate setups, and multi-carriage setups. The proposed systematics of multi-tool setups on lathe group machines is aimed at developing machining accuracy models and can serve as a basis for developing recommendations on cutting modes for these CNC machines. The proposed classification of multi-tool setups forms the foundation of the methodological support for the CAD system of lathe-automatic operations and serves as the basis for creating next-generation CAD systems for lathe operations.
Enumerating Structures: Applications of the Hyperoctahedral Group in Combinatorial Species
Authors: Pemha Binyam Gabriel Cedric
Published: December 2024

Combinatorial species provide a framework for counting and classifying for counting and classifying combinatorial structures. A species assigns a set of structures to each finite set, respecting the notion of isomorphism. This approach facilitates the enumeration of various combinatorial objects. The hyperoctahedral group, also known as the signed permutation group, consists of permutations of a set of signed elements. This group plays a crucial role in combinatorial algebra, particularly in the enumeration of certain structures, such as various types of trees and graphs. Generating series, both ordinary and exponential, are powerful tools in combinatorial enumeration. Combining these concepts allows for deeper insights into the relationships between structures and their enumerative properties, paving the way for advanced combinatorial theory and applications in various mathematical fields.

Objective. To analyze the repercussions of neck pain on the quality of life of health professionals in intensive care units.

Methods. Cross-sectional, descriptive and correlational study, carried out with 94 health professionals (21 nurses, 13 physical therapists and 60 nursing technicians) in Intensive Care Units of two medium-sized hospitals in a municipality in the far south of Brazil. An instrument containing variables of sociodemographic and work environment characterization was applied; the Neck Bournemouth Questionnaire (NBQ) and the WHOQOL-Bref were applied.

Results. There was a predominance of female professionals (88.3%), white (78.8%), aged 30 to 39 years (34.1%), with family income between one and two minimum wages (31.9%) and weekly workload between 31 and 40 hours (67%), night shift (54.3%), time of professional experience of one to five years (38.3%) and one job (73.4%). Neck pain and disability showed significant negative correlations with quality of life. The relationship was weak with the physical (r: -0.218; p=0.035) and psychological (r: -0.280; p=0.006) domains, and moderate with social relationships (r: -0.419; p<0.001), environment (r: -0.280; p<0.001) and general quality of life (r: -0.280; p<0.001). Overall quality of life showed a moderate correlation with the feeling of anxiety (r: -0.431; p<0.001) and depression (r: -0.515; p<0.001) of professionals in the last week.

Conclusion. Neck pain caused repercussions in the physical, psychological, social, environmental and general quality of life of health professionals in intensive care units.

Background: Colombia is joining global initiatives to mitigate climate change through bioethanol production, as it has large sugar cane plantations and sugar mills, particularly in the Valle del Cauca region. One of the main by-products of the bioethanol industry is vinasse, which consists mainly of water, organic solids and heavy metals. Some of the compounds present in vinasses, such as melanoidins and phthalates, show genotoxic, mutagenic and carcinogenic activity in onion cells, tilapia and aquatic organisms. Various methods, such as bio-oxidation and Fenton reaction, have been used to reduce the organic load of vinasses. Among the most commonly used assays to study genotoxicity and mutagenicity are single cell gel electrophoresis (comet assay) and the Ames test.
Objective: In this study, the genotoxicity in human lymphocytes and the mutagenicity in Salmonella typhimurium induced by different dilutions of vinasse produced at the bioethanol production plant in Frontino, Antioquia, before and after being subjected to biooxidation and Fenton processes, were evaluated.
Methods: Genotoxicity was evaluated by the comet assay in human lymphocytes, and mutagenic activity was evaluated by the Ames test using Salmonella typhimurium strains TA98 and TA100, with and without the addition of microsomal enzymes (S9). Both tests were applied to each type of vinasse considered in this study, including raw vinasse (RV), bio-oxidised vinasse (BV) and Fenton oxidised vinasse (FV). Results: The results showed that at RV doses above 3%, viability decreased to values between 70% and 88%, whereas for BV and FV, viability remained above 93% and 94%, respectively. Vinasse was also found to have a dose-dependent effect on genotoxicity. However, no mutagenic activity was observed in any of the Salmonella strains evaluated, indicating that vinasse does not induce mutations.
Conclusion: The importance of addressing vinasse pollution and treatment methods to reduce its toxicity is emphasised. However, further research is needed to fully understand the risks associated with vinasse exposure and to develop effective mitigation strategies.
Pentecostal Liturgical Spaces
Authors: Andrew Daniel
Published: December 2024

The Anglican Communion recently faced a threat of a split between revisionist and conservative groups about the acceptance of LGBTQIA+ members and ministers in liturgical spaces or their exclusion based on their status. The study aims to use the journey of the Anglican Communion as a case study to find out whether these positions are also prevalent in liturgical spaces in Pentecostal congregations and whether it is a contested or embracing space towards LGBTQIA+ members and ministers. The study employs decolonial and intersectional approaches to critically analyse ecclesial pronouncements of the Apostolic Faith Mission of South Africa, a Classical Pentecostal church in South Africa, to determine whether these position statements are conservative or revisionist; whether Pentecostal liturgical spaces are contested or embracing for LGBTQIA+; and if not, what can be done to transform Pentecostal liturgical spaces into welcoming and embracing spaces for LGBTQIA+ members and ministers. The Apostolic Faith Mission of South Africa, standing in the Classical Pentecostal tradition, can find in their tenet of the priesthood and prophet-hood of believers, a democratic and transformative principle, that is inclusive of LGBTQIA+ members and ministers; Pentecost offers a humanizing pneumatological space that embraces the God-given humanity of the LGBTQIA persons and cultivate respect for their human rights to live without fear of discrimination, bias and prejudice in the household of faith. Such Pentecostal liturgical spaces reflect the queer sociality of the Azuza Street Revival.
Seeking phronesis from Indigenous knowledge for eco-pastoral care during the African Anthropocene
Authors: Brunsdon Alfred Richard
Published: December 2024

The article brings practical theology into dialogue with African Indigenous Knowledge (AIK). The conversation stands in service of informing eco-pastoral care during the Anthropocene. The Anthropocene is framed in the African context to arrive at the notion of the African Anthropocene which poses unique challenges to the continent. Eco-pastoral care is envisaged as the active engagement of faith communities in biodiversity conservation. As it is assumed that practical theology and pastoral care are at their core Western notions, the research is performed as part of the contextualization discourse, seeking theoretically to further embed them in the African context. This motivates the discourse with AIK as an ancient source of wisdom that may further motivate African faith communities to act as pastoral stewards of the earth as it may resonate with African culture and ways of being in the world. This research proposes that the task of practical theology resides in initiating and stimulating conversations with African faith communities who are the custodians of AIK that can lead to the construction and practice of eco-pastoral care.
Influence of ambient storage on weight, color, and TSS in golden delicious apples: a correlational study
Authors: Kassebi Salma , Korzenszky Péter Emőd
Published: December 2024

This research explores the interplay between weight loss, color transformation, and total soluble
solids (TSS) in Golden Delicious apples during storage at room temperature. Across six weeks, a freshly
harvested batch of Golden Delicious apples underwent scrutiny in a controlled environment, maintaining
around 24⁰C and 60% humidity. The study aimed to unravel the post-harvest physiological shifts in apples,
explicitly focusing on factors affecting consumer appeal and shelf life. Methodologically, weight loss was
precisely tracked using a high-precision scale, while color alterations were quantified via a portable
colorimeter, yielding CIELAB L*, a*, and b* values. A refractometer was used to assess TSS, which
indicated sweetness and ripeness. Correlation analysis revealed a strong link between weight loss and color
shift, with a less pronounced yet significant connection between TSS and the other variables. These findings
enrich our comprehension of the post-harvest dynamics of Golden Delicious apples, carrying implications
for adequate storage and marketing tactics. This research supports the principles of the circular economy by
enhancing the efficiency of post-harvest processes and minimizing waste through better storage practices.
By understanding these factors, producers can reduce spoilage and extend the shelf life of apples, contributing
to more sustainable food systems.
Bezier curve shaped lamellae in cross flow dryers
Authors: Keppler István
Published: December 2024

Recent advancements in dynamic modeling, supported by improved computational technologies,
have enabled detailed investigations of particle motion within drying equipment. Under and over drying of
harvested crops causes significant financial losses in agriculture. To overcome this issue, we analyzed the
particle motion in cross flow dryers using analytical and numerical modeling techniques. In our earlier work
we determined the theoretically optimal lamella geometry shape, using the Brachistochrone problem and
finding the cycloid curve. The manufacturing problems of creating an approximate cycloidal curve for our
experimental investigations showed us that it is not a simple task to solve. To overcome this issue, we
investigated the possibility of using other geometries close to the original cycloidal one. This study explores
the influence of Bezier curve-shaped lamellae on particle residence time. By examining various geometries
and tribological parameters, the research aims to identify an optimal lamella design that minimizes under- or
over drying while maintaining ease of manufacturing.
THE MYTHOLOGEME OF “BULGAKOV'S KIEV”: SOVIET/RUSSIAN NEOTOTALIARISM IN ACTION
Authors:   H. Skovoroda Institute of Philosophy of the National Academy of Sciences of Ukraine, Kyiv, Ukraine, HRABOVSKY Serhii
Published: December 2024

The article is devoted to one of those theoretical and practical problems that became extremely relevant in connection with the Russian-Ukrainian war. The author of the article turns to the study of the phenomenon of the so-called "Bulgakov's Kiev", which is one of the forms of the imperial myth about Kyiv as a "real Russian city". Russian- Soviet cult writer Bulgakov, who had openly Ukrainophobic views, and in his prose and dramatic works he consistently falsified Ukrainian reality and events in Kyiv during the Ukrainian Revolution. The author of the article shows that the opinion of some modern cultural figures, as if Ukrainophobia in Bulgakov's works is completely devoted to his heroes, and the writer himself is free from it, does not correspond to reality. First, Bulgakov‘s entire texture texts are imbued with the denial of the completeness of Ukrainian as such - from language to politics; as for, for example, Ukrainian book publishing, which was organized on a very high level during the time of Hetman Pavlo Skoropadskyi, it simply does not exist for Bulgakov's heroes. Second, every stroke of Bulgakov's works emphasizes the "Russianness" of Kyiv. Third, there is the essay "The City of Kyiv" (1923), where the writer directly expresses his own views, based on a brutal falsification of pre-revolutionary and post-revolutionary life in the main city of Ukraine. Bulgakov categorically denies the very fact of the existence of science, literature and theater in Kyiv at that time, while the achievements of Ukrainian scientists are highly valued in Germany and other countries, Rylsky, Zerov and other neoclassical poets are active, and the Berezil theater with its studios has gained well-deserved popularity. What's more: Bulgakov called the main drawback of the Ukrainian autocephalous church the fact that its priests shave their beards (in fact, not everyone did so, but truthfulness was not one of the writer's virtues). And Bulgakov considered the biggest disadvantage of Kyiv to be the fact that it is located too far from Moscow, from its influence, and the surrounding Ukrainian space influences it too much. The article describes the process of formation of the latest cult of Bulgakov, starting from the second half of the 1960s, one of the key places in which the mythologeme of "purely Russian Kyiv" settled in the form of "Bulgakov's Kiev". This mythologeme has become a component of the current Russian totalitarian mythology, therefore, its deconstruction and destruction are necessary.
