Structure and Deformation Behavior of Polyphenylene Sulfide-Based Laminates Reinforced with Carbon Fiber Tapes Activated by Cold Atmospheric Plasma
Authors: Kosmachev Pavel V. , Panin Sergey V. , Panov Iliya L. , Bochkareva Svetlana A.
Published: December 2023

Low-temperature plasma treatment with atmospheric discharge with runaway electrons (DRE) was shown to be an efficient way to activate carbon fiber’s (CF) surface and subsequently increase its interlayer shear strength (ILSS) values. It was demonstrated that an acceptable ILSS level was achieved after a DRE plasma treatment duration of 15 min. The treatment of CFs resulted in their surface roughness being increased and their functional groups grafting. The XPS data showed a change in the chemical composition and the formation of reactive oxygen-containing groups. SEM examinations of the PPS/CF laminates clearly demonstrated a difference in adhesive interaction at the PPS/CF interface. After the DRE plasma treatment, CFs were better wetted with the polymer, and the samples cohesively fractured predominantly through the matrix, but not along the PPS/CF interface, as was observed for the sample reinforced with the untreated CFs. The computer simulation results showed that raising the adhesive strength enhanced the ILSS values, but reduced resistance to transverse cracking under the loading pin. In general, higher flexural strength of the PPS/CF laminates was achieved with a greater interlayer adhesion level, which was consistent with the obtained experimental data.

Published: December 2023

A smart thinning operation refers to an advanced method of selecting and cutting trees to be thinned based on digitally captured forest information. In smart thinning operations, workers use the coordinates of individual trees to navigate to the target trees for thinning. However, it is difficult to accurately locate individual trees in a forest stand covered with a canopy, necessitating a precise real-time positioning system that can be used in the forest. Therefore, this study aimed to evaluate the applicability of the global navigation satellite system real-time kinematic (GNSS-RTK) device in a forest stand through analysis of its positioning accuracy within the forest environment and evaluation of the operational range of the single-baseline RTK based on analysis of the positioning precision and radio signal strength index (RSSI) change with increasing distance from the base station. The results showed that the root mean square error (RMSE) of the horizontal positioning error was highly accurate, with an average of 0.26 m in Larix kaempferi stands and 0.48 m in Pinus koraiensis stands. The RSSI decreased to a minimum of −103.3 dBm within 1 km of distance from the base station; however, this had no significant impact on the horizontal positioning precision. The conclusion is that the GNSS-RTK is suitable for use in smart thinning operations.
Radio Frequency Interference Mitigation in Synthetic Aperture Radar Data Based on Instantaneous Spectrum Forward Consecutive Mean Excision
Authors: Wang Zijian , Yu Wenbo , Li Jiamu , Yu Zhongjun , Zhao Yao , Luo Yunhua
Published: December 2023

Radio frequency interference (RFI) poses major threats to synthetic aperture radar (SAR) systems. Due to the suppression of useful target signals via high-power RFI, the SAR imaging quality is severely degraded. Nevertheless, existing studies on RFI mitigation mainly focus on narrowband filtering, while wideband RFI mitigation methods are relatively lacking and perform non-robustly. In this paper, an RFI mitigation scheme is proposed based on instantaneous spectrum forward consecutive mean excision (FCME), which is suitable for both narrowband and wideband RFI mitigation. The SAR echo signal is first transformed into a time–frequency (TF) domain through a short-time Fourier transform (STFT). On this basis, the instantaneous spectra polluted via RFI are detected via a kurtosis-based statistical test and then filtered via FCME to achieve RFI mitigation. Finally, connected component analysis is applied as a safety measure so as to avoid the unnecessary loss of useful target signal. The combination of FCME and connected component analysis enables the proposed method to thoroughly filter out RFI while retaining more useful target signals compared with other competing methods. The experimental results on real SAR raw data validate the effectiveness of the proposed method.

Published: December 2023

The noise-like behavior of geomagnetic anomalies observed in Tlamacas station (the Popocatepetl volcano, Mexico), linked to the ionization produced by intensive radon release, is presented in the experimental part of the study. The magnetic-field perturbations produced by electrical currents due to micro-discharges on the terrain irregularities are considered in a theoretical model. The simulations demonstrated that the discharge mechanism can generate perturbations with magnitudes of up to 1–10 nT in the ultra-low frequency (ULF)) range of 10−3–10−1 Hz. ULF Magnetic-field perturbations can be higher within storm-weather conditions under an accumulation of electric charges in clouds in the mountainous regions.
Investigation of the Deterioration of Basu Granite Mechanical Properties Caused by Freeze–Thaw Cycles in High-Altitude Mountains in the Eastern Part of the Tibetan Plateau, China
Authors: Liu Jixin , Guo Changbao , Deng Tianye , Ren Sanshao
Published: December 2023

Mountains composed of granite are generally regarded as stable geological formations. However, in Alpine and high-altitude mountains in the eastern part of the Tibetan Plateau, geological hazards such as collapses and landslides occur frequently due to the deterioration of granite mechanical properties caused by the freeze–thaw cycles. To investigate this phenomenon, a freeze–thaw cyclic mechanical test is conducted on granite from the Basu area, and the rock’s damage trend during the freeze–thaw process is analyzed through wave velocity and nuclear magnetic resonance (NMR) tests. The results indicated that the internal damage of granite increases and its wave velocity decreases significantly with increasing the freeze–thaw cycles, implying a decline in the rock’s integrity. Furthermore, the development pattern of the NMR T2 relaxation time distribution indicates that the crack size range of naturally weathered rock samples further increased after freeze–thaw cycles, whereas less-weathered rocks showed a more concentrated range of crack sizes. Triaxial compression tests conducted on rock samples after the freeze–thaw cycles showed that parameters such as the uniaxial compressive strength, elastic modulus, internal friction angle, and cohesion of the rock decreased with increasing freeze–thaw cycles, while a significant change of Poisson’s ratio was not observed. Based on the test data and theoretical analysis, a freeze–thaw damage constitutive model of the Basu granite can be established to simulate and predict the overall variation in rock stress and strain under various confining pressures and freeze–thaw cycles. Hopefully, the present study will provide useful guidance for research on the hazard mechanism and hazard prevention of granite sand-sliding slopes in the Basu area.
The Six Critical Determinants That May Act as Human Sustainability Boundaries on Climate Change Action
Authors: Santos Filipe Duarte , O’Riordan Tim , Rocha de Sousa Miguel , Pedersen Jiesper Strandsbjerg Tristan
Published: December 2023

Significant advances have been achieved in multilateral negotiations regarding human development and environmental safeguarding since the 1972 UN Stockholm Conference. There is much greater global awareness and action towards sustainability. However, sustainability has persistently been sidelined, leading to the identification and definition of a transgressed “safe and just space for humanity”. Here we develop a new evolutionary approach and methodology to explain the reasons why sustainability continues to be a difficult challenge for contemporary societies to adopt. We argue that these originate in six major biological, social, psychological, political, and cultural critical determinants that resulted from human biologic and cultural evolution. Although they are essential for human prosperity and wellbeing, these characteristics may also act as human sustainability boundaries. It is possible to reduce the inhibiting power of each critical determinant in the pathways to sustainability, a vital process that we term softening. Identifying, knowing, and softening these impediments is a necessary first step to achieving sustainability through greater self-knowledge and transformational processes. The application of the present methodology is restricted here to the climate change challenge. We examine the ways in which each human sustainability boundary is capable of obstructing climate action and offer possible ways to soften its hardness.
Sustainable Operation and Maintenance of Offshore Wind Farms Based on the Deep Wind Forecasting

Published: December 2023

Offshore wind farms are becoming a pivotal solution to address the increasing energy demand worldwide and reduce carbon emissions to achieve a sustainable energy sector. Considering the higher operational and maintenance cost of offshore wind farms, it is important to make a good maintenance plan to guarantee the system’s reliability and reduce the total cost related to maintenance activities at the same time. Because maintenance planning is a long-term decision problem and the wind force is random, long-term wind force prediction is needed to help managers evaluate the loss caused by maintenances to be executed in the future. However, long-term wind force prediction is naturally complicated, which is much harder than the short-term (e.g., day-ahead) prediction widely investigated in the literature. In order to overcome this difficulty, we design a deep learning framework combining variational mode decomposition, a convolution neural network, long short-term memory network, and full-connected network. Using the public data from the city of Leeds, the prediction accuracy of the above framework is validated by comparing it with other prediction techniques. Then, the predicted wind force is input into the established optimization model determining preventive maintenances during a predefined period. Because the uncertainty of wind force is replaced by the prediction value, the optimization model can be established as a mixed-integer linear programing model, which only contains limited variables and can be solved quickly. Lastly, an abundance of numerical experiments are conducted to validate the effectiveness of the proposed optimization model, based on which some managerial insights are provided to the managers of offshore wind farms about the optimal operations and maintenance strategy. The research outcome will greatly promote the development of the wind power industry in the future.

Coastal climate services play a crucial role in developing customised climate information for diverse end-users and stakeholders. To build climate-resilient societies, decision-makers should be empowered through easy access to powerful tools that enable timely adaptation to future and ongoing hazards. For this reason, fit-for-purpose climate services are needed to conduct accurate historical characterisation and projections for interpretative studies on climate- and water-related risks at the local coastal scale. The EU-funded SCORE project (Smart Control of Climate Resilience in European Coastal Cities) utilises climate and marine services for the development of smart technologies that support nature-based solutions to address specific concerns, including rising sea levels, coastal erosion, and coastal flooding due to extreme weather events. As part of the SCORE project, decision-makers will be able to address climate change-related coastal effects in their own cities through novel participatory approaches (Coastal City Living Labs—CCLLs). As part of this framework, this work (i) discusses the main requirements for the identification of fit-for-purpose coastal climate services for local-scale impact studies in European coastal cities based on CCLL requests and prior knowledge and (ii) provides relevant parameters and features that fulfil the users’ needs.

Published: December 2023

In order to investigate the mechanical behavior of FRP-reactive powder concrete composite tanks with floating tops (FRPCTs) subjected to gravity, twenty-two full-scale FRPCTs were designed with varying parameters for the inner diameter of the storage tank (D) and the thickness of the reactive powder concrete (tc). Based on nonlinear constitutive models and the contact of the materials, and considering tank–liquid coupling, three-dimensional finite element refined models of FRPCTs were established under gravity with ADINA8.5 finite element software, and finite element models of FRPCTs under gravity were verified based on theoretical frequency formulae and existing static tests. Then, the influence of the regularity of different parameters on the equivalent stress, hoop stress, radial stress, and axial stress of the FRPCTs was obtained, and the stress distributions of FRPCTs were clearly described. The results show that the natural frequency of FRPCTs increases gradually with an increase in the height of the tank liquid (Hw); however, the natural frequency of FRPCTs reduces with an increase in D. The equivalent stress, hoop stress, radial stress, and axial stress of the FRP plate and RPC decrease slowly with an increase in tc. The axial stress of the inner RPC increases with an increase in D. The equivalent stress of the inner FRP plate subjected to gravity is distributed in a W shape, the hoop stress, and the axial stress of the FRPCTs are distributed in a U shape, and the radial stress of the inner FRP plate is distributed in an I shape. The maximum displacement occurs in the middle of the FRPCTs, and the bonding between the FRP plate and the concrete is better. Finally, a calculation formula for the variation in the regularity of the tc is developed with different D, and design and construction suggestions for FRPCTs are given, which can provide technical support for the application of the FRPCTs in practical engineering.
Towards a Transcultural Approach for Inter-Professional Communication in Complex IT Project Teams—Aiming to Avoid Cross-Functional and Cross-Hierarchical Conflicts
Authors: Scarlat Cezar , Bărar Daniela-Anca Sârbu
Published: December 2023

IT projects are becoming increasingly complex due to rapidly advancing technologies, the need to tackle more difficult problems, and the involvement of a larger variety of experts with different backgrounds and experiences from different countries and cultures. It is also common for these teams to often work remotely in virtual settings. In this context, besides conflicts between IT project team members, cross-functional and cross-hierarchical organizational conflicts might emerge as well. These conflicts can vary in terms of their origin, nature, and intensity. This paper is a qualitative study focused on understanding interpersonal communication-based conflicts in multicultural and multidisciplinary IT project teams. The purpose is to find a common approach that can mitigate and eventually resolve these conflicts, aiming to promote shared knowledge and ultimately reduce the gap in understanding and the likelihood of conflicts. Both secondary research (a literature survey) and primary research (involving experienced managers and experts from project teams in the Romanian IT industry) were conducted in order to reach the objectives, besides sets of lessons learned and recommendations, to develop a framework for systematic conflict analysis and to propose a practice for a transcultural framework of common team vocabulary. To achieve these, a number of conflicts were investigated in IT project teams and corresponding cases. Based on the research findings, the authors concluded that a more formal approach is needed to address the problem of conflicts. From a theoretical standpoint, this paper suggests the concept of management diversity and provides a typology of organizational conflicts. Nevertheless, the framework for systematic analysis of conflict typology (FACT) and the framework of common team vocabulary in the multicultural environment of IT organizational project teams, as well as the sets of lessons learned and recommendations, might be useful and inspiring for both scholars and managers, not only in the IT sector.

In recent years, numerous viruses have been identified from ticks, and some have been linked to clinical cases of emerging tick-borne diseases. Chinese northeast frontier is tick infested. However, there is a notable lack of systematic monitoring efforts to assess the viral composition in the area, leaving the ecological landscape of viruses carried by ticks not clear enough. Between April and June 2017, 7101 ticks were collected to perform virus surveillance on the China–North Korea border, specifically in Tonghua, Baishan, and Yanbian. A total of 2127 Ixodes persulcatus were identified. Further investigation revealed the diversity of tick-borne viruses by transcriptome sequencing of Ixodes persulcatus. All ticks tested negative for tick-borne encephalitis virus. Transcriptome sequencing expanded 121 genomic sequence data of 12 different virus species from Ixodes persulcatus. Notably, a new segmented flavivirus, named Baishan Forest Tick Virus, were identified, closely related to Alongshan virus and Harz mountain virus. Therefore, this new virus may pose a potential threat to humans. Furthermore, the study revealed the existence of seven emerging tick-borne viruses dating back to 2017. These previously identified viruses included Mudanjiang phlebovirus, Onega tick phlebovirus, Sara tick phlebovirus, Yichun mivirus, and three unnamed viruses (one belonging to the Peribunyaviridae family and the other two belonging to the Phenuiviridae family). The existence of these emerging tick-borne viruses in tick samples collected in 2017 suggests that their history may extend further than previously recognized. This study provides invaluable insights into the virome of Ixodes persulcatus in the China–North Korea border region, enhancing our ongoing efforts to manage the risks associated with tick-borne viruses.

Authors: Stelzl Anika , Fuchs-Hanusch Daniela
Published: December 2023

Austria’s water utilities are facing new challenges due to advancing climate change. In recent years, changes in water demand have been observed. Water demand forecast models are required to assess these changes and react to them in a sustainable way. In this study, an existing modeling approach was extended with new climate indices. The multiple linear regression model was applied to different study sites. The model was trained with a training dataset and validated with a test dataset. The performance of the model was assessed using common parameters, such as the mean absolute percentage error. In a further step, the modeling approach was applied to climate projections to estimate the change in water demand for three different representative concentration pathways (RCPs). The change in water demand due to population growth was then considered and combined with the change due to climate change. RCP2.6 shows an average 14% increase in water demand for the period 2051–2070, with climate change (average increase of 0.7%) playing a negligible role. For RCP4.5, an increase of 16% is predicted, while the highest increase of 19% is observed in RCP8.5. Population growth is responsible for most of the increase.

Published: December 2023

As an emerging contaminant, the presence of microplastics is widespread in the environment. However, current research regarding the removal of microplastics by drinking water treatment plants (DWTPs) remains insufficient. This study aims to investigate microplastics in water and sludge in four DWTPs in Zhengzhou; these DWTPs have different water sources. The results revealed that the abundance of microplastics in raw water ranged from 12.80 ± 0.80 to 25.07 ± 1.67 n/L. Overall, fibers and fragments ranging from 10 to 100 μm constituted the primary components. The proportion of white and transparent microplastics was the highest. Among the ten polymer types detected, polyvinyl chloride, polyphenylene oxide, and polyethylene terephthalate were the predominant ones in raw water; polyethylene terephthalate emerged as the prevalent polymer type in treated drinking water, with both polyethylene terephthalate and polyvinyl chloride being primarily present in sludge. The removal rate of microplastics ranged from 45.8% to 74.5%. Furthermore, the removal rates at the sedimentation tank outlet accounted for more than 50.0% of the total removal rate. The abundance of microplastics in sludge was significantly higher than that in water, indicating a concentrated environment for the persistence of microplastics. The proper disposal of sludge has emerged as one of the challenges requiring our attention.
Insights into the Physicochemical Parameters, Microbial Community Structure, and Functional Variations in Biodegradation of N-Alkane Derivatives from Fischer–Tropsch Wastewater

Published: December 2023

This study provides a theoretical baseline on the application of chemical and microbiological indicators as rapid system performance monitoring tools that will allow for timely corrective measures to maintain and improve the bioremediation performance of the Fischer–Tropsch wastewater (FTWW) treatment plants. Microorganisms isolated from the sediments and water samples collected from site 1 of Blesbokspruit wetland exhibited the highest biodegradation efficiency of up to 98.04% and 92.85%, respectively, in 96 h reaction time using batch culture media spiked with 300 ppm short chain n-alkane derivatives. The highest COD reduction rate was observed during the first 24 h of biodegradation, and it steadily declined thereafter. The decline in pH from 7.0 to 6.3 was observed in the 96 h reaction time and was attributed to the production of acidic secondary metabolites and the entrapment of the produced CO2 within the batch media. The ORP also declined from the aerobic zone to the anaerobic zone within 24 h (day 1) reaction time. The EC and TDS results were also indicative of the rate of consumption of essential nutrients during the biodegradation process, which could be related to biochemical reactions involved in biodegradation of n-alkane derivatives. Proteobacteria and Firmicutes were the prevalent phyla during the biodegradation of the n-alkane derivatives. Enterococcus and Escherichia genera were more dominant on most days of biodegradation, therefore, indicating that these genera were actively involved in the biodegradation process of the n-alkane derivatives. These genera displayed a positive correlation with EC, ORP, pH and TDS in the four days of biodegradation for batch cultures inoculated with microorganisms from the water and sediments samples collected from the Blesbokspruit wetland. The results obtained demonstrated that physicochemical and microbiological indices can be used to infer the biodegradation rates, patterns and system operations in FTWW bioremediation.

Проведена работа по изучению результатов скрещивания животных англерской породы с красной степной и их помесями. Для этого были сформированы 4 группы бычков: I — чистопородные особи красной степной породы, II — помесные бычки I поколения (1/2 англерская ×1/2 красная степная), III — животные II поколения (3/4 англерская ×1/4 красная степная) и IV — помесные бычки III поколения (7/8 англерская ×1/8 красная степная). Живая масса телят при рождении существенно не различалась. На завершающем этапе эксперимента превосходство по живой массе молодняка IV группы над аналогами из I, II и III групп составило 73,2 кг (14,00%), 54,8 (10,48%) и 21,9 кг (4,19%) соответственно. Масса туши бычков из IV группы была выше, чем у сверстников из I, II и III групп, на 49,3 кг (17,61%), 41,3 (14,75%) и 10,0 кг (3,57%) соответственно. Наибольшей убойной массой, которая составила 289,3 кг, обладали бычки IV группы. Самыми высокими массой и выходом мякоти отличались туши молодняка из IV группы — 230,6 кг и 82,3%. Химический состав среднего образца говядины показал, что наибольшее содержание сухого вещества было обнаружено в образцах молодняка из II группы — 37,33%. При этом самое высокое содержание протеина было в говядине бычков из IV группы — 20,43%. Белково-качественный показатель говядины во всех группах подопытного молодняка колебался от 5,39 до 5,79, что указывает на хорошее качество мяса. Полученные данные показали, что животные англерской и красной степной пород остаются надежным, целесообразным и экономически обоснованным источником производства говядины на территории России, а их помеси имеют хорошие показатели мясной продуктивности.

В настоящее время развитие отечественной пищевой промышленности направлено на обеспечение населения качественной молочной продукцией. Одно из направлений связано с проведением исследований по идентификации генотипов крупного рогатого скота и улучшением действующих программ для изучения генов, сцепленных с хозяйственно полезными признаками. В молоке содержится множество важных для питания человека белков, основным из которых является казеин. Выделяют 4 его фракции: αs1-казеин, αs2-казеин, β-казеин и k-казеин. Каппа-казеин напрямую связан с гидрофильными свойствами казеина молока, влияющими на технологические процессы при производстве молочнокислых продуктов. За образование данной фракции отвечает ген каппа-казеина (CSN3), расположенный в 6q31-хромосоме. На данный момент обнаружено 15 аллелей этого гена, которые отвечают за генетический полиморфизм. Самые распространенные из них — А и В, отличающиеся друг от друга двумя заменами аминокислот. В сочетании они дают 3 основных генотипа: АА, АВ и ВВ. При изучении их влияния на свойства молока и молочных продуктов были получены противоречивые данные у различных авторов. Часть исследователей утверждают, что генотип ВВ по CSN3 является приоритетным по удою, содержанию белка, жира и технологическим свойствам, другие ученые получили противоположные результаты — в пользу генотипов АА и АВ. Вследствие этого актуально проводить генотипирование крупного рогатого скота по гену каппа-казеина для дальнейшего изучения и развития селекционных программ в племенном молочном скотоводстве.

Introdução. A Síndrome das Pernas Inquietas (SPI) é uma condição neurológica caracterizada por sensações desconfortáveis nas pernas, muitas vezes acompanhadas pelo desejo incontrolável de movê-las. Em casos leves, podem ser suficientes mudanças no estilo de vida, mas em formas mais graves ou associadas a problemas de saúde subjacentes, intervenções terapêuticas são necessárias. A suplementação oral de ferro é uma abordagem comum, tanto para pacientes com deficiência de ferro quanto para aqueles sem essa carência. Objetivo. Esta revisão integrativa investigou a eficácia da terapia oral de ferro em pacientes com SPI, comparando-a com outras abordagens terapêuticas ou mesmo ausência de tratamento. Método. O estudo foi realizado de acordo com o protocolo PRISMA. Também foi utilizado escalas para avaliação da qualidade dos estudos. Foram identificados 7 estudos elegíveis, incluindo ensaios clínicos e estudos de follow-up, que analisaram uma variedade de parâmetros clínicos e laboratoriais. Resultados. Os resultados foram mistos, com alguns estudos relatando eficácia significante da terapia oral de ferro na melhoria dos sintomas de SPI e no aumento dos níveis de ferritina. No entanto, houve relatos de efeitos adversos e baixa adesão ao tratamento em alguns casos. Conclusão. A terapia oral de ferro pode ser benéfica para pacientes com SPI, mas sua eficácia varia e deve ser considerada em conjunto com outros fatores clínicos. Pesquisas futuras devem continuar explorando essa abordagem terapêutica e identificar subgrupos de pacientes que podem se beneficiar mais com a suplementação de ferro oral.
Autocensura en el lenguaje de la biblia griega. Huellas de formas lingüísticas afroasiáticas que afectaron el lenguaje bíblico.
Authors: Gienini Olga
Published: December 2023

Durante el período helenístico, la comunidad judía de Alejandría tradujo al griego sus textos sagrados. Esta obra conocida como la Septuaginta (LXX) que era, a la vez, un texto religioso para ser leído en la liturgia sinagogal y una fuente de jurisprudencia extranjera para los tribunales egipcios, muestra los desafíos que los traductores debieron enfrentar en ese proceso. Ellos desarrollaron un lenguaje propio, críptico para la audiencia griega profana aunque inteligible para la judeo-helenizada, que surge probablemente de un proceso de autocensura que intentó minimizar los enfrentamientos entre las comunidades judías residentes en Egipto y sus generosos mecenas pero implacables soberanos.
Sobre la permanencia de lo teológico-político: la Revolución francesa, la doctrina de los dos cuerpos del rey y la Constitución de 1791
Authors: Escalante Pablo
Published: December 2023

Este artículo examina la permanencia de la doctrina teológico-política de los dos cuerpos del rey en la Revolución francesa a través de la Constitución de 1791. Este análisis se desarrolla en dos partes. La primera parte ofrece una crítica a la interpretación republicana del principio de la soberanía nacional adoptado en 1789, y propone en su lugar una que se ajusta al horizonte de sentido de la monarquía. La segunda parte subraya la naturaleza teológico-política de la Revolución y el trabajo simbólico que se realizó sobre la noción de la soberanía, con la intención de resaltar los esquemas de organización y de representación propios de la doctrina de los dos cuerpos del rey que se mantuvieron en la Constitución de 1791.

El cubo y el azul
Authors: Goldfeder André
Published: December 2023

El artículo explora dos modos de presencia de la poesía en Assez (1966), Imagination morte imaginez (1965) y Sans (1969), textos incluidos en la colección Têtes-mortes (1967/1972). De un lado, señalaremos algunos ecos de la Poesía, entendida como patrimonio literario y humano sedimentado, dicho y “desdicho” por el texto beckettiano. De otro, desplegaremos este comentario a la vista de sus relaciones con ciertos ecos de poesía, entendida como modo discursivo. Por eso hay una atención a tres aspectos de la poesía en Têtes-mortes: en forma de referencias, directas e indirectas, a autores y problemas asociados a la tradición poética; a través de modos de elaboración y sobredeterminación de las dimensiones rítmicas, sonoras y visuales, que sugieren la exploración de una región de tensión entre prosa y poesía; y sobre la problemática del símbolo y la relación entre lenguaje y vida. En estos tres niveles, se abordará la poesía como instancia que pone en escena las relaciones entre tiempo y olvido, elaboradas en clave de paradoja performativa que se despliega en diferentes direcciones. Se trata de asociar lo poético en Têtes-mortes a una dinámica en la que la enunciación de la pérdida de los objetos está sobredeterminada por los contratiempos de una enunciación que los hace presentes de modo intermitente. En definitiva, a través de la intersección entre la temporalidad póstuma de los ‘restos” y los “huecos”, la poesía irrumpiría en ecos que sobredeterminan su propia negación. Así que este aspecto pone en primer plano el papel estratégico del principio y del final en los textos tratados.
El estatuto de la poesía en la ensayística de Samuel Beckett y T.S. Eliot
Authors: Lasa Cecilia
Published: December 2023

Este trabajo se propone estudiar la ensayística de Samuel Beckett y de T. S. Eliot como espacio de reflexión sobre su composición poética. Ambos poetizan la crisis del lenguaje y de las formas literarias heredadas del siglo XX en un contexto signado por enfrentamientos bélicos armados y encuentran en el ensayo el género que les permite construir una base conceptual en torno a su quehacer artístico: cuál es la naturaleza, la función y el estatuto del lenguaje poético, cuál es la concepción de poesía que se despliega en sus poemas, entre otras teorizaciones. No obstante, los autores difieren en el tratamiento que hacen del ensayo como forma: el escritor irlandés explora, desde el humor y con una actitud lúdica, la hibridez del género al emplear para su composición procedimientos propios del teatro y de la poesía; el escritor norteamericano-inglés, por su parte, hace un uso instrumental del género, funcional a su quehacer poético, y no convierte a su producción ensayística en objeto de experimentación poética. En este sentido, mientras que para T. S. Eliot la poesía se manifiesta en sus ensayos principalmente como contenido sobre el cual teorizar, para Beckett el ensayo constituye una expresión discursiva que, tanto como el teatro, puede convertirse en objeto de poetización.
El cuerpo, la experiencia y la crítica: la fenomenología de la intercorporalidad en tránsito hacia la fenomenología crítica
Authors: García Esteban A.
Published: December 2023

La fenomenología crítica se presenta como una diversificación temática, una redefinición de los objetivos y una revisión del método de la fenomenología clásica. Este trabajo se enfoca en el tercero de estos aspectos para mostrar de qué modo la reformulación merleau-pontiana del método fenomenológico (a partir de su énfasis en el carácter corporal y relacional del yo) abrió la posibilidad de integrar dos perspectivas usualmente consideradas incompatibles, y en cuya intersección se sitúan precisamente los estudios fenomenológico-críticos. Estas dos perspectivas conciernen, por un lado, a la reflexión fenomenológica con su foco en la experiencia vivida en primera persona, y por otro a investigaciones de las ciencias humanas o estudios constructivistas, genealógicos o críticos que subrayan la constitución social, histórica y política de la identidad y la experiencia. Si la fenomenología crítica enfatiza la necesidad de una rectificación o ampliación crítica del método de la fenomenología clásica, nos preguntamos si los análisis de las condiciones sociales de la constitución de la experiencia no necesitan recurrir a alguna modalidad de descripción fenomenológica precisamente para ser críticos.
Fenomenología, Marxismo y prácticas de autoconciencia feminista
Authors: Suárez Tomé Danila , Córdoba Mariana
Published: December 2023

El propósito del presente trabajo consiste en analizar la conexión existente entre feminismo, fenomenología y marxismo, por medio de la exploración de las prácticas de autoconciencia y la teoría del punto de vista feminista. Sostenemos que las prácticas de autoconciencia feminista y su sucedánea teoría del punto de vista feminista se apartaron de sus raíces fenomenológicas y marxistas. Esto contribuyó a la reapropiación de cierta retórica perteneciente a estas prácticas por parte de la ideología capitalista dominante, con un contenido y un propósito sustantivamente diferentes. Afirmamos que para producir teoría situada desde Latinoamérica es necesario partir de la materialidad de la propia experiencia. Para esto, reivindicamos las raíces fenomenológicas y marxistas de las prácticas de autoconciencia y las teorías del punto de vista feminista. Finalmente, argumentamos que es posible recuperar la impronta revolucionaria de estas prácticas, en el marco del paradigma del feminismo post-identitario e interseccional actual, en especial, en su expresión latinoamericana.
Naturalismo, política y religión en Giordano Bruno
Authors: Bianchi Agustín
Published: December 2023

La restauración nolana de la auténtica filosofía y de la auténtica imagen del universo exige una “expulsión de la bestia triunfante”, es decir, una reforma que purgue los vicios y las nocivas costumbres causantes según Bruno de la crisis que estaba viviendo la Europa del siglo XVI. Esta es la premisa principal del Spaccio de la Bestia Trionfante (1584). A partir de esta obra, la filosofía Nolana comienza a virar desde una perspectiva metafísico-ontológica hacia una perspectiva ético-política.
En el pensamiento bruniano, la religión es parte de la ley que constituye el Estado; instrumento fundamental para propiciar la paz dentro de la sociedad civil y la sana relación entre los hombres, la Naturaleza y Dios. Por este motivo, puede entenderse la reflexión bruniana sobre la reforma de la moral y la religión presente en el Spaccio como su filosofía política. Así planteada, la filosofía política del Nolano tendrá como principal objetivo reunificar ley divina, ley natural y ley civil y recuperar la verdadera utilidad de la religión como instrumentum regni, es decir, como herramienta político-pedagógica para garantizar la buena convivencia en la sociedad y la virtud en los hombres. Proponemos, entonces, que en el pasaje desde una reflexión ontológica hacia el plano civil-político son importantes los conceptos de vicissitudine, coincidentia oppositorum y vinculum amoris.
Hilemorfismo y generación natural en el Comentario de Tomás de Aquino a la Metafísica de Aristóteles
Authors: Iversen Francisco
Published: December 2023

En el momento de mayores precisiones sobre la sustancia primera, Metafísica VII es un libro complejo que nuclea numerosos problemas metafísicos y lógicos de la tradición aristotélica. Aparecen allí, por ejemplo, el problema de la unidad de la metafísica, el hilemorfismo, el problema de la ousía primera, el problema del contenido de la definición, etc. En especial, los capítulos 7 a 9 tienen pasajes misteriosos donde se desvía el foco de la discusión que venía dándose en el libro, en tanto abordan los tipos de generación. Asimismo, el análisis hilemórfico de la generación natural que ahí aparece es central para comprender la génesis humana en Aristóteles y la tradición que lo sigue. Ahora bien, en el Comentario a la Metafísica de Tomás de Aquino todo lo antes mencionado toma dimensión y se resignifica a cuento de las discusiones escolásticas.

La propuesta de este trabajo tiene dos partes. La primera aspira a leer el análisis de la generación natural en dichos capítulos de la obra aristotélica: con el objetivo de determinar: (i) las notas propias de la doctrina hilemórfica allí presentada; (ii) sus implicancias (a) para con el problema de compatibilizar la noción de ousía de las Categorías y la Metafísica y, (b) para con el problema del contenido de la definición. En segundo término, se analizarán las lectiones 6-8 del Comentario tomista para determinar la reconstrucción que Tomás hace de lo anterior y el impacto que aquello tiene sobre sus doctrinas

Como si en la danza el dinero no importara
Authors: Clavin Ayelén
Published: December 2023

En los procesos productivos y las relaciones laborales de las prácticas dancísticas tienen lugar intercambios económicos que pueden comprenderse en los términos del capitalismo de mercado. Sin embargo, es posible observar además otros modos de relación que dan cuenta de una dimensión económico-afectiva. Este artículo se propone como una aproximación a comprender esos modos de intercambio en los que la afectividad y reciprocidad que se establece entre colegas artistas parece tener un papel fundamental. Algunos de los interrogantes que impulsan este trabajo son: ¿Qué fundamenta las lógicas de cooperación en la danza? ¿Cómo se explica la aparente falta de atención a la dimensión monetaria? ¿Cómo funcionan las relaciones en las que lxs participantes –colegas cercanos o amigos– se conceden tiempo y trabajo, y en las que el dinero pareciera no importar?
Opportunities and Challenges of Remote Sensing, Geospatial Data, and Machine Learning in Obtaining Accessibility and Location Information for Sustainable Development in Indonesia
Authors: Devara Terry
Published: December 2023

With the advancement of technologies so does the data collection method which creates a large, rapid, and diverse stream of data. Statistic Indonesia (BPS) has also encouraged to utilize this by starting to collect geospatial information on respondents and public facilities. To keep up with this a change needs to be made in processing methods to accommodate massive, high-dimensional, and multiform data collected in different forms such as machine learning. This progression also opens up a new opportunity for tackling various statistical data problems such as accessibility and location data. Remote sensing is one of the big data sources that undergoes a lot of changes shown in the high spatial and temporal resolution satellite imagery availability, together with the BPS geotagging data shows great promise in classifying land use and geospatial analysis. Even so, there are still some challenges in remote sensing as well as other geospatial data utilization. The goals of this review paper are to study the opportunities and challenges in utilizing remote sensing, geospatial data, and machine learning for accessibility and location information. In this paper, we explore the possibilities and limitations in its implementation into SDGs indicators that involve accessibility and location such as indicators 9.1.1, 11.1.1, 11.2.1, 11.3.1, and 11.7.1 including other variables needed for the calculation like access to public facilities. Moreover, our experiment using geotagging data shows potential in improving proportion estimation when compared to using a simple ratio. Our DEGURBA following the UN definition using machine learning LULC for dasymetric mapping also provides more insight compared to the existing data. We can conclude that there are great opportunities in applying remote sensing and other geospatial data to monitor the accessibility and location to further sustainable development in Indonesia.
