Authors: Liem Le , Pham Ngoc Nhan , Nguyen Thu Hien
Published: December 2024

Agricultural energy analysis and better energy use efficiency will contribute to sustainable development adapt to climate change and ensure maintainable production. A case study from Hau Giang province agriculture energy was conducted on the comparison between the cultivation of paddy rice (PR) and upland crops, including corn, mungbean (MB), and black sesame (BS). The life cycle assessment methodology was used to estimate energy consumption and biomass energy production. Based on input-output energy inventoried results, the energy use efficiency, energy productivity, specific energy, and net energy were analysed. Selected crops require 39,501 – 59,638 MJ ha–1 crop–1 that is higher than energy providing for PR. Crop cultivation requires a large amount of energy from fossil fuels and electricity (12,946 – 34,375 MJ ha–1 crop–1). Biomass production achieves 779,670 MJ ha–1 crop–1 through corn cultivation, follow by rice farming (198,723 MJ ha–1 crop–1), BS and BS production (103,292 and 63,012 MJ ha–1 crop–1, respectively). Corn and PR reach the best energy analysis index because of their high biomass production. This study’s results underline the benefit of net energy from agricultural systems case study in Hau Giang province (19,380 – 720,032 MJ ha–1 crop–1).

The present study was designed to evealuate the influence of different substrates on the yield and antioxidant properties of oyster mushroom (Pleurotus ostrestus) cultivated in 'bag-logs'. The substrates used in this study were: (1) maize straw, (2) beech sawdust mixed with wheat bran, and (3 and 4) maize straw mixed with spent coffee grounds mixed in a different ratio. Total phenolics, total flavonoids and total antioxidant acitivity of oyster mushroom were determined by the Folin-Ciocalteu method, Aluminium chloride method and Ferric Reducing Antioxidant Power Assay, respectively. The highest fruiting bodies yield of oyster mushroom was obtained from substrate 4 (maize straw mixed with spent coffee grounds in a ratio of 50:50), while the least was from substrate 1 (maize straw). Total phenolic contents ranged from 3.80 mg in oyster mushroom grown on substrate 4 (maize straw mixed with spent coffee grounds in a ratio of 50:50) to 4.85 mg of gallic acid equivalents g-1 dry mass in oyster mushroom form substrate 2 (beech sawdust mixed with wheat bran). Total flavonoid contents were very low in all analysed mushroom extracts. There was no significant difference between total antioxidant activities of oyster mushroom grown on different substrates.

Functional SNPs serve as biological markers that aid biologists and breeders in identifying genes linked to specific traits. This study explored the relationship between QTLs associated with drought tolerance and functional SNPs using two populations: Vada × Susptrit (V × S) and Cebada Cappa × Susptrit (C. Cappa × S). Bioinformatics tools were employed to analyze significant SNPs within QTL regions, revealing markers on chromosomes 1H, 2H, 3H, 5H, and 7H for the V × S population, and on 4H and 6H for C. Cappa × S. In total, 24 proteins/enzymes related to drought tolerance were characterized in the V × S population. At the same time, 10 were identified in C. Cappa × S. Notable proteins, including Phytochrome B and SAPK7, were located on chromosome 4H. These proteins play crucial roles in the plant's response to drought stress, with documented regulatory effects. Gene ontology analysis indicated four cellular components—membrane, nucleus, chloroplast, and proteasome complex—and five biological processes, such as oxidation-reduction and protein phosphorylation. The proteins exhibited diverse molecular functions, including ATP binding and kinase activity. Overall, the study highlights potential functional SNP markers for validating QTLs related to drought tolerance in barley.

Straight and helical plating with locking plates for proximal humeral shaft fractures – a biomechanical comparison under physiological load conditions
Authors: Halbauer Christian , Capanni Felix , Paech Andreas , Knop Christian , Merkle Tobias , Da Silva Tomas
Published: December 2024

Objectives

Helical plating is an established method for treating proximal humeral shaft fractures, mitigating the risk of iatrogenic radial nerve damage. However, biomechanical test data on helical plates under physiological load condition is limited. Hence, the aim of this study was to compare the biomechanical performance of helical and straight PHILOS® Long plates in AO12C2 fractures using static and cyclic implant system testing.

Methods

Helical and straight PHILOS® Long plates on artificial bone substitutes were tested under physiological axial static (n=6) and cyclic loading (n=12). The axial construct stiffness was the main parameter for comparing the biomechanical performance of the two groups. Mimicking a clinical scenario, the helical deformation was performed consecutively by an experienced surgeon using iron bending tools. The torsional angle was determined computationally from 3D-scanning models afterwards.

Results

Helical plating resulted in a significantly reduced axial construct stiffness in all test scenarios compared to conventional straight plating (static testing: p=0.012; cyclic testing: p≤0.010). No failure occurred within the range of physiological loading in both groups.

Conclusions

Helical plating favors multidimensional deformation of the test sample in lateral-ventral direction under axial loading, resulting in a reduced axial construct stiffness and in an increased interfragmentary movement. No biomechanical failure is to be expected within physiological load boundaries.
Obstacles during training of pregnant doctors in Germany before and after COVID-19: is there a need for change?
Authors: Fortmann Caroline , Johna Susanne , Groß Christiane , Niethard Maya , Puhahn-Schmeiser Barbara
Published: December 2024

Objectives

With the growing proportion of female practitioners in the medical field, management of pregnant medical doctors is an increasingly important concern. The 2018 amendments to the German Maternity Protection Act stipulate that pregnant doctors and students can and should be permitted to safely continue their work under strict protective measures. Despite these measures, the reality is that pregnancy still results in limits on professional advancement and attainment for many physicians. To improve this situation, we analyzed the current situation in Germany. Based on our analysis, we identified some areas in need of improvement and offered recommendations.

Methods

We performed a nationwide online survey that was sent to medical doctors and students via the physicians’ union Marburger Bund members’ mailing list. The survey’s main focus was on which kinds of clinical duties the pregnant doctors were assigned to, subdivided into four different time periods (under the previous and amended Maternity Protection Act, during COVID-19 pandemic and after), from 2016 to 2022.

Results

Our survey included 4,748 female medical doctors and students, with a balanced distribution across the four different time periods. The most striking restriction reported by our participants was a ban on performing surgeries and invasive procedures, an experience reported by 57–65 % of pregnant doctors and medical students before the COVID-19 pandemic and nearly 80 % since the pandemic. In addition, since the COVID-19 pandemic, a complete employment ban has been enforced upon nearly 50 % of the pregnant doctors. More than 50 % of pregnant doctors considered their careers to have been obstructed or curtailed by their pregnancies prior to the pandemic, with that number growing to two-thirds since the pandemic.

Conclusions

Pregnancy negatively impacts doctors’ training and careers. Many women are not allowed to perform surgeries and invasive procedures, even while some of these practitioners report that they wish to and are capable of continuing their work. Change is needed to support enthusiastic young female doctors and students and enable them to maintain their skills and professional advancement during pregnancy.
Автор и рассказчик в книге Э. Лимонова «Мои живописцы»: маска или подлинное Я?
Authors: Яновна Пекарь Яна
Published: December 2024

В статье исследуется проблема авторской маски. Особую актуальность эта давняя традиция приобретает в настоящее время, что связано с изменившейся социокультурной ситуацией. У массового читателя, находящегося под воздействием внетекстовой реальности, сформировалось клиповое мышление, что обусловило весьма тривиальный интерес читателя к искусству. Запрос аудитории на сокращение и упрощение смыслов вынуждает автора скрывать свое лицо за маской. На примере книги Э. Лимонова «Мои живописцы» показано, как практика текстопостроения ориентируется на определенного читателя и соотносится с коммерческой спецификой текста. Э. Лимонов, снижая историческую ценность известных полотен, переосмысливает возвышенный мир искусства, представляя его перед читателем как повседневную, наполненную осязаемыми элементами быта жизнь, в то время как символическое значение произведений художников разного времени им не учитывается.
The Syntax and Semantics of Converbs in Modern Slavic Languages
Authors: Nikolin-Dukai Lilla
Published: December 2024

The paper investigates the category of converbs in modern Slavic languages, a grammatical category exhibiting ongoing development. Converbs' morphological, syntactic, and semantic properties are examined across various Slavic languages. By comparing their syntax, usage, and semantics, the study aims to identify connections between the current state of converbs and the typological features of each language. Contrary to the initial hypothesis, the analysis reveals that modern Slavic languages exhibit significant variation in the syntax and semantics of converbs, highlighting the ongoing evolution of this grammatical category within the Slavic language family.

Published: December 2024

Este artigo analisa como a arquitetura escolar colaborou para a formação do imaginário republicano, a partir do Grupo Escolar Benjamin Constant, fundado em Belém-PA, durante a Primeira República. Para a pesquisa bibliográfica e documental foram utilizados como fontes os relatórios dos governadores da época e da diretora deste grupo. Apesar de esse Grupo Escolar Benjamin Constant fazer parte da criação de grupos escolares pelo país, vemos que sua arquitetura não se enquadrava nas diretrizes arquitetônicas para este tipo de instituição. Como razões, estão a crise da economia da borracha e, sobretudo, sua localização em bairro operário e periférico.

Educação, Tecnologia, Ideologia e o processo de desenvolvimento de Álvaro Vieira Pinto
Authors: Ferreira Gomes Geovane
Published: December 2024

Este artigo explora o conceito do desenvolvimento e sua relação com a tecnologia,  com base nos escritos de Álvaro Vieira Pinto. A partir de seu texto Ideologia e desenvolvimento nacional, investigamos os fundamentos que sustentam suas ideias presentes no livro O conceito de tecnologia, com foco na noção de consciência para o outro e na apropriação da tecnologia como patrimônio da humanidade para atender às demandas sociais. Vieira Pinto destaca a necessidade de construir uma ideologia nacional com base filosófica e estruturada no Estado. Essa ideologia, embora liberal, seria democrática, com participação ativa das massas e dos intelectuais, e, como evidenciado em suas obras, estariam intrinsecamente ligada à educação. Vieira Pinto argumenta que a apropriação da tecnologia, mesmo de origem estrangeira, pode servir como um estágio intermediário no processo de desenvolvimento nacional. A partir dessa perspectiva, examinamos como a educação tecnológica é abordada no meio acadêmico, onde frequentemente é associada à acumulação de capital, em detrimento das oportunidades vislumbradas por Vieira Pinto. Diante das disputas ideológicas presentes na sociedade brasileira, identificamos a dificuldade em encontrar elementos capazes de construir uma ideologia sólida para o desenvolvimento nacional. Essa lacuna constribui para a perpetuação do atual cenário da educação brasileira, postergado o desenvolvimento do país.

Published: December 2024

Neste artigo investigamos qual o papel dos engenheiros civis na construção de um imaginário de modernidade e progresso tecnológico no Brasil e de que maneira isso permanece na organização da educação em engenharia atual. A pesquisa é realizada por meio de uma análise histórica da bibliografia consultada, focada na segunda metade do século XIX, quando aconteciam as Exposições Universais que impactaram o pensamento da burguesia brasileira, edas transformações que ocorreram ao longo do século XX no ensino de engenharia. Além disso, faz-se também uma análise documental das atuais Diretrizes Curriculares Nacionais de Engenharia. Ao investigarmos a classe emergente dos engenheiros no país em relação com o que se considerava progresso, pode-se encontrar conexões com o ensino de engenharia do presente, como o determinismo tecnológico, a presença da inovação e a relação estreita com as empresas. Embora exista hoje uma preocupação com a responsabilização social e ambiental, salientamos a necessidade de uma educação em engenharia que seja crítica de si mesma.

Le retour sur le lieu de travail postpandémie et la fidélisation des employés : le rôle, les défis et les inquiétudes des gestionnaires de proximité dans cette nouvelle transformation
Authors: Morin Claire , Fortin-Bergeron Chloé , Austin Stéphanie
Published: December 2024

En 2022, alors que le télétravail était bien établi dans les organisations, le gouvernement du Québec mettait fin aux mesures sanitaires obligatoires et du même coup, enlevait l’obligation pour les entreprises de maintenir le télétravail à 100%. Pour nombre d’entre elles, l’abolition de ces mesures a enclenché un processus visant à ramener les employés sur les sites de travail, entraînant inévitablement de nouveaux défis, de nouvelles inquiétudes et toute l’incertitude s’y rattachant. L’objectif de cet article est de porter un regard sur le déroulement et la gestion du retour sur le lieu de travail postpandémie. Plus particulièrement, nous cherchons à comprendre comment les gestionnaires de proximité ont mis en application les directives organisationnelles et orchestré le processus de retour en présentiel de leurs employés de façon à maintenir et reconstruire leur engagement. Cet article s’inscrit dans le prolongement d’une première démarche de recherche réalisée en 2021 sur la fidélisation de la main-d’oeuvre en début de pandémie de COVID-19. Les résultats présentés reposent sur l’analyse de treize entrevues semi-dirigée réalisées entre les mois d’avril et décembre 2023. Ils montrent comment les gestionnaires de proximité ont réussi, ou non, à trouver un équilibre entre les attentes organisationnelles et les besoins des employés, les défis et les inquiétudes rencontrés ainsi que leurs rôles dans le déroulement du retour sur le lieu de travail postpandémie. Ils nous amènent aussi à constater que l’implication et la présence des gestionnaires de proximité auprès de leurs employés durant cette période de retour ont été des éléments primordiaux pour les aider à retrouver leurs repères au sein de l’organisation afin qu’ils se sentent pleinement investi dans la réussite de ce retour.
La transformation vers le numérique des organisations publiques : quelle rationalité et quelle légitimité?
Authors: Nicolini Vincent , J. Caron Daniel
Published: December 2024

La transformation vers le numérique est à l’agenda de nombreuses organisations publiques qui visent à tirer profit du potentiel des technologies de l’information et de la communication récentes. Or, la signification et la portée sont sujettes à des interprétations et des perceptions différentes qui vont varier en fonction de multiples facteurs internes et externes à l’organisation. Ceci impacte la rationalité de cette transformation, le sens organisationnel qu’on lui attribue et surtout ce que sera la transformation pour l’organisation. Cet article part de cette ambiguïté pour montrer comment la transformation vers le numérique est impactée par des discours qui lui sont en bonne partie extérieurs. Il examine d’abord trois discours servant à légitimer la transformation vers le numérique : le discours de la performance, celui du changement et de l’innovation et celui de la réforme bureaucratique. Il dégage ensuite, à l’aide de quelques exemples, des pistes d’interprétation permettant de saisir de façon plus fondamentale la signification de la transformation vers le numérique pour les organisations publiques.
Olin Downes and the Soviets
Authors: Bartig Kevin
Published: December 2024

In 1929 and 1932, the influential New York Times music critic Olin Downes toured the Soviet Union as a guest of the All-Union Society for Cultural Relations with Foreign Countries (VOKS), an arm of the Soviet government charged with cultural diplomacy. During these visits he attended performances, met with Soviet musicians, and surveyed music institutions. His reporting on these experiences garnered significant attention, given both Downes’s prominence and the fact that he was the first major US music critic to visit the Soviet Union since the Bolshevik Revolution. In this article, I show how this early example of US-Soviet musical exchange bolstered Downes’s professional authority and focused his critical agenda. I begin by reconstructing his Soviet tours and situating the critic in a story of interwar US-Soviet exchange that to date has largely overlooked the role of music and musicians. I then show that Downes constructed Soviet musical culture for US readers in ways that impacted his subsequent commentary on domestic matters. Significantly, key experiences in the Soviet Union stimulated his later advocacy of a nationally inflected voice for American music, an aspect of Downes’s work that is central to understanding the critic’s career and a crucial piece in the history of interwar musical nationalism and populism in the United States. More broadly, this study invites consideration of the varied roles played by critics during the interwar period, the international and cross-cultural dimensions of criticism, and the importance of interwar cultural exchange as a prehistory to Cold War music diplomacy.
Reevaluating Political Musiktheater and Reversing Colonialist History: Mauricio Kagel’s Mare Nostrum (1975)
Authors: Fitz Gibbon Elaine R.
Published: December 2024

Long ago, in mid-October, members of an Amazonian tribe discovered the Mediterranean. Having made the arduous journey across the Atlantic, the colonizers were fascinated by the strange peoples they encountered as they traveled around this newfound sea. Or so reports the narrator of Mauricio Kagel’s 1975 work of “sitting music theater,” Mare Nostrum: Discovery, Pacification and Conversion of the Mediterranean Region by a Tribe from Amazonia. Borrowing its title from the Imperial Roman name for the Mediterranean, “Our Sea,” Mare Nostrum is an operatic farce of European colonialism. Using the playful space of an imagined past, Kagel restages Latin American colonial legacies on the waters of the Mediterranean to meditate on power, violence, and the writing of history. This article employs theories of transnational experimentalisms to establish the centrality of mobility in Kagel’s work—a mobility, as the article argues, that is fundamental to the genre of experimental music theater. Themes of mobility suffuse Mare Nostrum, not only in the imaginative material of its dramatic plot, but in the work’s creative movement through music history and its play with iconic works of musical exoticism; in its entwinement with international networks of avant-garde performance; and in its portrayal of environmental devastation as a legacy of colonialism’s extractive structures. Reconsidering Mare Nostrum in light of urgent geopolitical crises of postcolonial and environmental violence, the article concludes with a provocation to reconceptualize the historiography of the mid-twentieth-century avant-garde with such works of experimental music theater at its center.
Current state of methods and algorithms for gene expression data clustering and biclustering: A survey
Authors: Yarema Oleg R. , Babichev Sergii A.
Published: December 2024

The analysis of gene expression data has grown increasingly complex with the expansion of high-throughput techniques like
bulk RNA-seq and scRNA-seq. These datasets challenge traditional clustering methods, which often struggle with the high
dimensionality, noise, and variability in biological data. Consequently, biclustering methods, which group genes and conditions
simultaneously, have gained popularity in bioinformatics. Biclustering is valuable for identifying co-regulated gene subsets under
specific conditions, aiding in the exploration of transcriptional modules and gene-disease links. This review examines both traditional
clustering and biclustering methods for gene expression analysis, covering applications such as patient stratification, gene network
identification, and drug-gene interaction studies. Key biclustering algorithms are discussed, focusing on their strengths and
challenges in handling complex profiles. The article highlights significant issues like hyperparameter optimization, scalability, and
the need for biologically interpretable results. Emerging trends are also reviewed, such as consensus clustering and distance metrics
for high-dimensional data, with attention to the limitations of evaluation metrics. The potential for these methods in diagnostic
systems for diseases like cancer and neurodegenerative disorders is also considered. Finally, we outline future directions for
enhancing clustering and biclustering algorithms to create a personalized medicine system based on gene expression data.
Moving object shape detection by fragment processing
Authors: Mashtalir Sergii V. , Lendel Dmytro P.
Published: December 2024

The development of information technologies related to the analysis of visual information is inextricably linked with the
methods of extracting various features or objects to facilitate their further analysis. This is due to the growing demands for visual data
from the user. At the same time exactly object detection is one of the most fundamental and challenging tasks in locating objects in
images and videos. Over the past, it has gained much attention to do more research on computer vision tasks such as object
classification, counting of objects, and object monitoring. At the same time, researchers almost never paid attention to the fact of the
shape of a moving object, and usually left this question for further analysis. At the same time, for example, for an object
classification, having an object with clear shape outlines as input would be useful. This study provides video fragment processing for
moving object shape detection. Our approach is based on dividing each frame into fragments that allow the present image frame as a
square matrix for a formal description. The rectangular video frame has been transformed into a square matrix by SVD (singular
value decomposition), where each element is a Ky Fan norm value used as a descriptor. Scene changes in the frame will affect Key
Fan norm fluctuations. Comparing the fragment norm changes with other fragment norm changes will allow us to assess how
significant these changes are. If the norm value exceeds the threshold value, we can include this fragment as part of the moving
object. By combining such fragments together, we will detect moving object shapes. The threshold is dynamic and depends on time.
In this study, we paid attention to calculating a threshold value for a fragment's reliable identification of a moving object. We also
note that the experiments were conducted for the case when there is a stationary camera (surveillance camera) and some moving
object in the field of view. And in this case, it was possible to obtain a clear contour of a complex shape for a moving object. More
complex cases of simultaneous movement of both the object and the camera will be considered later.
Association of leukocyte elastase in semen and seminal plasma with sperm parameters and pregnancy outcomes in male fertility
Authors: Das Mausumi , Gumssani Maha , Mullaney Julia , Henkel Ralf , Minhas Suks , Aquilina Marie Claire , Jayasena Channa N
Published: December 2024

Background

Semen analysis is the standard test for evaluating male fertility. However, it may not address all aspects of male infertility. This review explores the role of leukocyte elastase (LE) as a possible biomarker for male fertility by evaluating 28 corresponding studies.

Objectives

We aimed to explore how LE levels in semen relate to sperm quality and pregnancy outcomes.

Methods

This systematic review followed PRISMA guidelines and included studies from PubMed, Medline, Embase and Scopus (March 22–25, 2024) using the keywords ‘elastase’, ‘sperm’ and ‘semen’. Out of 897 identified articles, 334 were screened, leading to 90 full-text reviews. We included 28 studies reporting sperm parameters linked to LE and excluded non-English articles, reviews and animal studies. Data collected included study details, methods, population, LE levels, sperm characteristics and pregnancy outcomes. A narrative synthesis was used because of differing study designs. Quality assessment, using the National Heart, Lung, and Blood Institute tool, rated 21 studies medium quality, 6 high and 1 low.

Results

Only a limited number of studies reported a correlation between LE levels and sperm parameters, with no significant link to sperm concentration. Overall, we did not identify a strong association between LE levels and pregnancy or fertilization rates.

Conclusions

Although LE serves as a marker for seminal leukocyte concentration, its link to sperm quality and fertility outcomes remains weak and inconsistent. Based on current evidence, LE does not appear to be a reliable diagnostic marker for male infertility. Future studies should focus on standardizing LE measurement techniques and exploring its interaction with other semen parameters to clarify its role in male fertility.

By changing the temperature of chemical activation of plant biomass, nanoporous carbon materials with a specific surface area of up to 1050 m2/g were obtained. The obtained carbon materials were used to form composites with different percentages of conductive additive. Electrochemical impedance spectroscopy was used to investigate the physicochemical processes occurring at the carbon electrode/electrolyte interface in a 30% aqueous KOH solution.
The concentration of charge carriers in the obtained carbon materials was determined, the values of which are in the range of 6·1018 – 35·1018 cm-3, and its dependence on the temperature of thermochemical activation was established. It was established that an increase in the temperature of thermochemical activation from 600 ºС to 900 ºС leads to an increase in the capacity of the space charge region by almost 10 times. The formation of nanoporous carbon material/conductive additive composites contributes to the correlation between the values ​​of specific capacitance and electrical resistance for the studied materials.

Vanadium oxide thin films were fabricated using a multi-step deposition process involving magnetron sputtering and sequential annealing. The structural, vibrational, and nanomechanical properties of the films were investigated to elucidate the impact of phase composition on the performance of metal-insulator phase transition (MIT). X-ray diffraction (XRD) and Raman spectroscopy revealed a structural evolution from quasi-amorphous to nanocrystalline phases upon annealing, with transitions from VO₂ to textured V₄O₉ dominating the annealing process. The observed phase transition is accompanied by hardness increase from 0.9 GPa in the amorphous first layer to 11–18 GPa in all (crystalline) multi-layers. The hardening is attributed to development of well-ordered crystalline texture, which improved interatomic bonding and resistance to deformation. The vibrational Raman spectra obtained at various excitation wavelengths exhibit resonant sensitivity to different oxide phases, including the minority V3O7 phase not detectable by XRD and selective resonant probe of V4O9 phase only with 671 nm excitation. Temperature-dependent Raman and electrical resistivity measurements revealed superior MIT characteristics for samples with higher VO₂ content, despite the presence of other VₓOᵧ phases. These findings underscore the critical role of structural ordering in tuning the mechanical and functional properties of vanadium oxide films for advanced electronic and optical applications.

Economical and efficient transformation of lignocellulosic biomass into fuels, chemicals, and materials has drawn much attention in recent years. Catalytic chemical conversion is one of the most widely used technical ways in lignocellulosic transformation because of its high efficiency. However, the traditional chemical conversion is often carried out at high temperatures and large amounts of byproducts are formed during the conversion process. This is due in part because the used catalyst has low activity, selectivity, and stability. This causes the traditional chemical conversion process to have a high cost and to encounter difficulty in industrialization. The single atom catalysis approach provides a promising solution to improve the traditional chemical conversion process and decrease its process cost. Compared with the traditional catalyst, the single atom catalyst has not only lower cost but also higher activity, selectivity, and stability. It is becoming a new frontier in lignocellulosic conversion. This editorial will give a brief discussion about opportunities and challenges of using single atom catalysis for improvement of the lignocellulosic conversion.

The extracts of Schotia brachypetala were tested against the molecularly identified fungi Alternaria alternata, Botrytis cinerea, and Fusarium oxysporum, which cause early blight of tomatoes, gray mold of cucumber immature fruits, and Fusarium wilt, respectively. Leaves and branches of S. brachypetala were extracted using acetone and bio-assayed for their antifungal activity at 2%, 4%, and 6% when applied to white mulberry wood samples. Using high-performance liquid chromatography analysis, the most abundant compounds in leaf extract were kaempferol (37900 µg/g extract) and gallic acid (7480 µg/g extract), and in branch extract were gallic acid (3120 µg/g extract) and chlorogenic acid (1320 µg/g extract). By increasing the extract concentration to 6%, the percentage inhibition of fungal mycelial was significantly increased compared to the positive (Cure-M) and negative control samples. This study indicates that extracts from leaves and branches of S. brachypetala can be effective as bio-based agents in wood protection and that they can prevent the growth of pathogenic fungi.
TWILIGHT OF METAPHYSICS: THE PROBLEM OF NOTHINGNESS AND NIHILISM IN THE MARTIN HEIDEGGER’S PHILOSOPHY
Authors: LYUTY Taras
Published: December 2024

The article examines the problem of Nothingness and nihilism in Martin Heidegger’s views. In his early studies, Nothingness appears as a negation in the logical judgement. However, in further examinations, it relates to human existence. Nothingness is exposed in realization of the finitude of human life and death. Heidegger explains that human existence and Nothingness are connected through the experience of fear. To be fearful does not mean to be afraid of certain things, but to be able to see the perspective of non-existence. Nothingness that emerges in fear resembles transcendence, in other words, the ability to go beyond one’s own limits. Going outside the limitations of existence allows anyone to overcome the passiveness of life and start being concerned about one’s own existence. As a result, Heidegger’s philosophy of Nothingness was named nihilistic. However, Heidegger rethinks the problem of nihilism in the context of Nietzsche’s philosophy. He succeeds in showing that Nietzsche avoids the problem of Nothingness. In the Nietzschean vision, Nothingness is a characteristic of a world in which values are an appeal not to the earthly, but to the afterlife existence. That is why Nietzsche speaks of the need for a new set of values. Therefore, according to Heidegger, Nietzsche does not ask about the essence of Being, but simply assigns values to Being. Instead, in Heidegger’s philosophy, nihilism is a consequence of Western metaphysics ignoring the question of Nothingness. It is due to Nothingness that the question of Being becomes clear: without thinking of Nothingness, Being is not understood either. One can change the situation by asking again about Nothingness and Being. In general, the problem of nihilism in Heidegger’s philosophy changes significantly. First, he connects it with the historical movement of forgetting of Being, and later with a false interpretation of the essence of metaphysics. This thought is strengthened by the tendency of the dominance of technology, which dehumanizes the world. In conclusion, Heidegger’s philosophy is comparable to prophetism. Like Nietzsche, he seeks salvation from nihilism in art: poetry liberates from calculative rational thinking. Therefore, the question of the essence of thinking has not yet been raised in the West. The dominance of metaphysical thinking further distances a human from Being. At the same time, Heidegger insists on including the problem of Nothing in the question of Being, as ignoring it prevents the real overcoming of nihilism.
HUMAN-MACHINE INTERACTIONS: ALIGNING, ADAPTING, BEING AN AGENT
Authors: LAKTIONOVA Anna
Published: December 2024

In the paper, the touchstone points of the project “Towards an agency-based philosophy of (advanced) technology” are outlined. The main plot of this elaboration concerns human-machine interactions and appropriate interpretation of reciprocal aligning, adapting within involved into such interactions agents; as well as the status as such of being an agent. Into the theoretical and historical background of the project such spheres as Philosophy of Science, Philosophy of Technology, Philosophy of Engineering and Design Technological Actions, STS (Science and Technology Studies), Applied Ethics etc. could be invited. To treat agency as technology, reestablish the role of agency in technology is the most ambitious goal of the project: ‘activity as technology’ focuses on activities through technologies. The terms «agency» and «activity» are used in this paper synonymously with the basic Aristotelian meaning of agent’s potential capacity to act. The proposed by the author theory of action and agency (and correspondently defended in 2016 dissertation of Doctor of Philosophical Science) is to be applied into philosophical reflections about various problems of dealing with currently continually appearing flourishing fields of artificial intelligence, machine learning (including deep learning methods and simulation methods), inventing computers and codes, numerically controlled machines and robots, computer-chip equipped devices, smart objects etc.

Os missionários redentoristas bávaros e o Brasil como viagem de (re)fundação. Entre experiências e expectativas, 1894-1930
Authors: Rodrigues Gomes Filho Robson
Published: December 2024

Objetivo: analisar o processo de transformação das expectativas dos missionários redentoristas bávaros no Brasil, a partir das novas experiências vividas em seu campo missionário entre o final do século XIX e início do XX. Metodologia: utilizaremos como pressuposto teórico básico as categorias de “campo de experiência” e “horizonte de expectativas” desenvolvidas por Reinhart Koselleck, além da proposta de uma espécie de “antropologia do viajante” proposta por François Hartog. Originalidade: oferecer aos estudos das missões europeias no Brasil uma perspectiva analítica que transita entre o sujeito e sua instituição, na medida em que busca-se analisar situações individuais que dizem respeito à própria dinâmica institucional. Em termos de recorte espacial, focaremos nas experiências missionárias em Goiás (no sertão brasileiro), como forma de compreender as adaptações dos ideais de “missão” e “vocação” em um dado espaço de fronteira. As fontes principais utilizadas são cartas e crônicas dos missionários bávaros, escritas entre 1894 e 1920. Conclusões: apontamos que os ideais missionários de missão, vocação e sacrifício levaram à ideia de (re)fundação da pátria alemã no Brasil, transformada pelas dificuldades enfrentadas no processo de tensão cultural aqui encontrado.
Hernán Rodríguez Vargas. Siete mitos de la Independencia de la Nueva Granada (1810-1819). Imágenes, imaginarios y politización de la historia. Bogotá: Pontificia Universidad Javeriana, 2023. 276 páginas.
Authors: Cortés Guerrero José David
Published: December 2024

El libro de Hernán Rodríguez Vargas está basado, como lo advierte su título, en la obra de Matthew Randall.1 En el texto se analizan algunos procesos por medio de los cuales se construyeron, desde el siglo XIX, imaginarios sobre la independencia del país, pero que, con la ayuda de la difusión iconográfica y mediática se convirtieron en mitos tanto en una historia heroica, como en una “historia oficial” (p. 29). En este caso el mito significa algo ficticio que se acepta como cierto, total o parcialmente (p. 32), en contravía de lo que se entendió como mito en sus orígenes, esto es, una explicación verosímil a fenómenos de la naturaleza. De esta forma, Rodríguez Vargas intenta desmontar los mitos explicativos de la independencia, mostrándolos como ficticios, pero que la historiografía colombiana, desde el siglo XIX, ha querido mostrar como explicaciones verdaderas. Los siete mitos tratados por el autor son: el de los héroes de la patria; el de la poca participación de la mujer; el de la homogeneidad y completitud de la Independencia; el de las falsas equivalencias; el del Edén nacional; el de la Iglesia despolitizada; y, el de la consumación del pasado. Para cada uno de ellos dedica un capítulo en donde muestra cómo se construyó el mito y cómo se proyectó a lo largo del siglo XIX e, incluso hasta la actualidad, con el apoyo de las imágenes.
