Von der Pflicht zur Chance: Energie- und CO2-Management mit digitalen Zwillingen
Authors: Schnicke Frank , Müller-Zhang Zai
Published: February 2025

In diesem Beitrag wird aufgezeigt, wie Unternehmen mithilfe von digitalen Zwillingen regulatorische Anforderungen der EU, das ESG-Reporting (Environment, Social, Governance), und das deutsche Lieferkettengesetz einfach erfüllen und gleichzeitig den entstehenden Datenschatz nutzen können. Als Grundlage dient der grüne digitaler Zwilling, der als Verwaltungsschale realisiert ist und relevante Daten für Gerät, Prozess und Produkt aggregiert. Auf Basis dieser Daten können Unternehmen den Einsatz erneuerbarer Energien optimieren und ihren Energieverbrauch reduzieren. Als Resultat können regulatorische Anforderungen erfüllt und Kosten eingespart werden. So können sich Unternehmen auf den Mehrwert der Energiewende konzentrieren, anstatt sich mit der dafür notwendigen Infrastruktur zu beschäftigen.

Authors: Zulfah Zulfah , Rahayuningsih Margareta , Marianti Adity , Alfan Sidik Muhammad
Published: February 2025

Gili Iyang Island is one of the islands in Sumenep district, Madura Indonesia, which is known as the island with best oxygen after research by Lembaga Penerbangan dan Antariksa Nasional (LAPAN) with an average oxygen level of 20.9%. In 2022, there will be research by the Faculty of Advanced and Multidisciplinary Technology, Air Langga University which states that the oxygen level on Gili Iyang Island has an oxygen level of 20.3%. As a tourist village in Sumenep district, its existence is an attraction for tourists for oxygen tourism. How can the community and local government protect this area so that it remains sustainable? This research aims to see the extent to which the conservation of Gili Iyang Island is carried out using an ecophilosophy perspective. This research was conducted using a qualitative approach through data triangulation including interviews, observation, and documentation and supported by literature studies. The research results show that the people of Gili Iyang is quite good at protecting the nature of this island. There have never been any complaints about illegal felling of trees or pollution activities that have caused oxygen levels to drop significantly. Many trees grow abundantly on this island, while people's use of motorized vehicles is still relatively normal, and the cleanliness of the island at many points is also well maintained. Even so, wise behavior towards nature as taught by ecophilosophy must continue to be socialized and intensive education given to local communities. The eco-philosophy pattern implemented by the Gili Iyang community must be maintained and improved through sustainable conservation on the island they live on.
Applicability of the occupational justice and occupation-based community development frameworks for social transformation: Marikana event
Authors: Mthembu Thuli
Published: February 2025

Background: The Occupational justice framework is significant in enabling communities to collaborate with occupational therapists to strengthen social vision and to enhance the occupational potential. It has been highlighted that the occupational justice framework could be used in conjunction with Occupation-based Community Development programmes to enrich social transformation through engagement in community-led occupations. However, little is known about the applicability of both occupational justice and Occupation-based Community Development frameworks in designing programmes for communities that experienced collective trauma after the Marikana event. Purpose: This commentary explores and describes the Marikana event in terms of the occupational justice framework and its outcomes of occupational injustice. It further unpacks the occupation of protest and the factors predicting protest using the Marikana event. Key Issues: Critical reflections of mineworkers' movements are used to enhance an understanding of the occupational lens of the protest in addressing conditions of social reproduction in communities. Conclusion: The applicability of the occupational justice and Occupation-based Community Development frameworks can help occupational therapy clinicians, educators, and students to collaborate with communities through a cycle of critical consciousness to achieve social vision, social transformation, and healing. Recommendations are provided in relation to community-centred occupational therapy practice, education, and future research within a South African context. Â
"It's a catch-22 situation": Perspectives of male mental health service users with serious mental disorders on their community integration following a residential-based rehabilitation programme in South AfricaCann
Authors: Gamieldien Fadia , Galvaan Roshan , Duncan Madeleine
Published: February 2025

Introduction: Residential-based rehabilitation programmes were introduced to relieve the resource burden of long-term hospitalization in South Africa. More men of working age than women in South Africa require longitudinal support from public mental health services and the majority live in communities characterised by poverty and unemployment. There is limited research on male mental health service users' perspectives on the impact of residential-based rehabilitation programmes on their community integration. Method: An instrumental case study design was applied, and five male participants were identified through purposive sampling. Observations, semi-structured interviews, community maps and document analysis were used to collect data. Thematic cross-case analysis of qualitative data was done. Findings:Â  The theme, It's a catch-22 situation, describes the participants' ambivalence towards the residential-based rehabilitation programme contribution to their community reintegration after discharge. Three categories, namely 'It's not just what you call it', 'There's no one size for all', and 'It's tricky choosing between places to go and things to do', capture how the perceived inflexibility of the programme curtailed their adjustment to community living. Conclusion: Participants proposed co-constructing their recovery plan with mental health professionals so that it is more personalised in supporting them as they adapt to emergent occupational challenges. A seamless continuum of support between different levels of care should be implemented.
Care and Compassion in Healthcare Provision
Authors: Sykes Leanne , Bester Janette
Published: February 2025

The quality of patient care forms the basis of all doctor-patient relationships. However, it requires more than mere provision of what is necessary to maintain or restore their health, and should encompass an emotional connection, and a desire to help them. Care covers a wide range of activities and is often seen as the technical and procedural aspects of medicine, while compassion revolves around the relational aspects of patient care. It requires clinicians to be able to express empathy and understanding, share their patients’ feelings, be available, communicate, try to provide support and encouragement, and treat them with respect and dignity. This paper discusses care and compassion and explores issues such as whether a person can be taught to care and or show compassion; if too much compassion could cloud a practitioner’s judgement; if it’s possible to deliver good care without being compassionate; and whether a person who has never experienced compassion can develop this ability.

Using Polyvinyl alcohol (PVA) fiber and micro silica sand has adverse effects on the economic and sustainable advantages of Engineered Geopolymer Composites (EGCs). This study suggests replacing PVA fiber with polypropylene fiber (PP) in producing sustainable reinforced slag-based-engineered geopolymer composites (SEGC) subjected to thermal cycling and repeated loads. PP and PVA fibers, with a 2% content as a volume fraction were selected to reinforce the EGCs. The study examined mass loss, microstructural characterization, static (monotonic) and cyclic loading measurements, tensile properties, and flexural properties. The results obtained indicate a substantial reduction in the strength of lightweight SEGC under thermal cycling. The density of LW-EGC and ECC composite ranged between 1758 for ECC and 1870 kg/m3 for PVA-EGC, while the statistic stress ranged between 37.35 for PVA-ECC and 63.78 for PVA-EGC. However, the flexural strength under static and cyclic loading of LW-ECC (LW-ECC) samples showed substantial improvement due to the increased reaction rate of fly ash particles under high temperatures. Microstructure analysis revealed that SEGC samples suffered more severe damage than ECC specimens when subjected to various cooling and heating cycles. These micro-cracks contributed to defects in the residual mechanical behavior of lightweight SEGC specimens.

This study evaluates the self-healing efficiency of bio-concrete incorporating Bacillus megaterium (067) and Bacillus licheniformis (598), combined with Steel Fibre Reinforced Concrete (SFRC), for sustainable construction. Concrete specimens were prepared with bacterial concentrations of 103, 105, and 107 cells/ml, alongside steel fibre additions of 1%, 1.5%, and 2% by weight. Artificial cracks were introduced, and the healing performance was assessed through visual and microstructural analyses. Mechanical properties, including compressive, split tensile, and flexural strengths, were systematically tested. Results showed significant enhancements, with compressive strength improving by up to 18% and crack widths reducing by over 60% due to microbiologically induced calcite precipitation (MICP). Scanning Electron Microscopy (SEM) confirmed calcite deposition within cracks, validating bacterial involvement in self-healing. This research highlights the potential of integrating bacteria into SFRC to improve mechanical durability and self-healing, offering an innovative path toward eco-friendly and resilient construction materials.

Este estudio descriptivo examina, desde categorías de la Lingüística Sistémico-Funcional y algunas propias derivadas del corpus, las selecciones de Tema en los marcos teóricos de una muestra de conveniencia conformada por veinte artículos de revistas indexadas colombianas en el área del lenguaje. Además, caracteriza la interacción con el sistema de información y el análisis del significado de Tema marcado y no marcado en español. Los resultados demuestran la centralidad de la función textual del Tema, que se cumple mayormente mediante los Temas experienciales y, en menor medida, por Temas textuales. Los Temas experienciales se realizan mediante grupos nominales que se refieren a información Recuperable (Dada o Accesible) o grupos pronominales con función anafórica. Con función catafórica son recurrentes Emisores y Circunstancias de Ángulo. Se identificaron verbos en posición temática, que en español tienen la función de mantener el flujo del discurso, al tiempo que construyen el compromiso heteroglósico propio de los Marcos Teóricos. La presencia de nominalizaciones simples y complejas en posición temática realiza la función de compactar información. Se necesita realizar más estudios detallados en español, con corpus de diversos géneros y registros, que permitan afinar diferencias entre Tema marcado y no marcado en español, y establecer los límites entre información Nueva y Accesible.
Educators in Transition: Unpacking Argentinean Teachers' Attitudes Towards AI in Higher Education
Authors:   Universidad Nacional de Salta, Bottiglieri Laura Inés , Irrazabal María Fernanda ,   Universidad Nacional de Salta, Ramallo Carina ,   Universidad Nacional de Salta
Published: February 2025

Artificial intelligence (AI) technology is revolutionizing the way we live, learn, and work. In academic settings, AI tools such as chatbots, machine translation and plagiarism detectors are becoming increasingly popular. However, as the use of AI by students becomes more widespread, concerns about the impact it may have on learning, academic integrity, and the role of traditional teaching methods are growing. This paper aims to explore the perspectives of Argentinean teachers on the use of AI in higher education and on its advantages and drawbacks. Through qualitative interviews and quantitative surveys, we investigated how much knowledge teachers have about AI and whether or not they perceive its potential benefits and challenges and its impact on their teaching practices. Results show that L2 instructors exhibit varying levels of familiarity and experience with AI tools, specifically Generative Machine Translation (GMT) and chat Generative Pre-trained Transformer (GPT). Notably, there exists a degree of reluctance among instructors towards incorporating AI tools into language classes, stemming from concerns related to potential hindrances to language development, over-reliance on technology, and accuracy, among other considerations.
A Gendered Blue Economy? Critical Perspectives Through Women’s Participation in Peru
Authors: Llanos Sara Doolittle , Garteizgogeascoa María , Gonzales Isabel E.
Published: February 2025

Peru’s maritime waters and their natural resources have long been appropriated as part of the country’s economic development. While several historical analyses have covered the management and use of marine resources, few have focused on gender relations in these processes. In order to help fill this gap, we use an ethnographic approach, through the qualitative analysis of interviews carried out between 2021 and 2022 with three women involved in Peru’s artisanal small‐scale fisheries and scallop aquaculture industry. Through their life trajectories, we discuss how these women became key actors within the Peruvian blue economy and the role that concrete and situated gender relations played in that process. We present a critical analysis of women’s agency and involvement in the blue economy and how the economic opportunities offered are constrained by gender norms, male dominance, and the precarious nature of (in)formal labor. We suggest a need to shift from a focus on blue growth to a more inclusive concept of blue justice that deals with structural inequalities ingrained in current modes of extractivism and aims to secure fair opportunities for all genders in marine‐related activities.
A CRITICAL REVIEW OF METHODOLOGICAL CRITIQUES IN CONTROL CHART DESIGN
Authors: Aslam Muhammad , Rashedi Khudhayr A. , Alshammari Tariq S.
Published: February 2025

In this paper, we present a comprehensive review of recent critiques on the various methodologies employed in the design of control charts. Initially, we provide a succinct overview of the published critiques, summarizing their key points and arguments. Following this, we highlight the primary concerns and flaws identified in these critiques. Our analysis demonstrates that many critiques of the methodologies used in control chart design lack logical coherence or are based on incomplete studies. Additionally, we demonstrate that certain critiques are fundamentally flawed and misleading, which can create causing confusion among professionals working in the field of statistical process control. By addressing these issues, we aim to clear up misconceptions and contribute to the ongoing enhancement of control chart methodologies.

The fundamental principle of neuro-oncology is to remove the tumor as much as possible, while minimizing the impact on healthy brain structures. In the case of high-grade gliomas (HGG, high-grade gliomas), resection volume continues to be a critical parameter that significantly affects the prognosis for patients. Numerous studies show that an increase in the volume of the removed tumor correlates with improved survival rates. This review presents a wide range of innovative intraoperative therapeutic technologies, each of which makes an important contribution to improving the treatment outcomes of patients with brain tumors. It is important to note that each of these technologies has unique characteristics, limitations and advantages. For example, LITT provides high-precision destruction of tumor cells with minimal damage to surrounding healthy tissues, but it requires special equipment and qualified personnel. PDT has a selective effect on the tumor, but its effectiveness depends on the type of photosensitizer used and the depth of light penetration. Brachytherapy, in turn, provides the possibility of local irradiation of the tumor, minimizing the impact on surrounding structures, although it may require a long period of observation of the patient after the procedure. Collaboration between the scientific community, industry, and regulatory authorities will play a key role in the successful implementation of these technological innovations in clinical practice
Algunas prácticas discursivas en El coloquio de los perros: el espacio fronterizo entre el sermón y la murmuración
Authors: Chacon Espindola Vânia Pilar
Published: February 2025

Ciertos criterios poéticos y retóricos se observan en las producciones escritas de los siglos XVI y XVII en España, adecuados a los estándares de racionalidad de corte absolutista como: ingenio, juicio, prudencia, discreción y disimulación honesta, como es el caso de la novela ejemplar El coloquio de los perros de Miguel de Cervantes (1613). Este artículo tiene como objetivo establecer homologías, así como identificar las estructuras que se repiten en un sistema de representación, cuyos principios teológico-políticos autorizan un discurso de carácter satírico.
Reseña. El Abencerraje. Estudio y notas de Eugenia Fosalba, Madrid, Real Academia Española (Biblioteca Clásica, 33), 2017
Authors: Vicente Baldrich Mireia
Published: February 2025

Esta edición, al cuidado de Eugenia Fosalba, presenta las tres versiones distintas de El Abencerraje en un único volumen, que permite al lector consultar y valorar por sí mismo las cualidades de cada una. La versión más antigua, conocida como Crónica es la que más se aproxima al texto original, de carácter oral, escrita no antes de 1548. Esta versión, muy desdeñada por los estudiosos, dejó un espacio crítico muy útil que la editora ha aprovechado con una edición crítica anotada y justificada dentro de las coordenadas interpretativas modernas. La segunda versión apareció en el Inventario de Antonio de Villegas, y la tercera, la más leída y difundida, se insertó al final del libro IV de la Diana de Montemayor (edición vallisoletana). La editora aborda en el estudio introductorio los problemas irresolubles hasta el momento del Abencerraje: ¿Quién es el autor de la Crónica?, ¿cuál es la evolución textual de las diferentes versiones?, y/o ¿fue Montemayor quién firmó la versión inserta en la Diana? Sobre la autoría de la Crónica, Fosalba  apunta a Jerónimo Jiménez de Urrea, hombre de temperamento humanista, militar y escritor, responsable de la famosa traducción del Orlando furioso y la Arcadia, como la más plausible. Acerca de la precedencia de las versiones queda  demostrado como la Crónica es anterior a I y D con indicios irrefutables como son las notas eróticas y las palabras malsonantes incluidas en algunos pasajes de C que se tijeretean en  I  y en D. Finalmente un exhaustivo cotejo de la versión aparecida en la Diana con otras obras de Montemayor avalarían la hipótesis de que el escritor luso está detrás del Abencerraje pastoril.
Adiáforas y variantes de autor en La Araucana (1589-1590)

Fernando de Herrera entre Francisco Pacheco y Pablo de Céspedes: hacia la edición póstuma
Authors: Montero Juan
Published: February 2025

Tras la muerte de Fernando de Herrera (1597) y la pérdida de una parte de su obra, su figura se convirtió en objeto de memoria y reivindicación para algunos de sus amigos y próximos. Es el caso de Francisco Pacheco y de Pablo de Céspedes, como testimonian una epístola del primero al segundo y el fragmento de un poema de Céspedes que Pacheco reproduce en su Libro de retratos. El análisis de ambos textos lleva a concluir que ya en los albores del XVII había quien sentía la necesidad de publicar una edición póstuma de los versos herrerianos y reconocer así su papel decisivo en la evolución cultista de la poesía española desde 1580 en adelante.

A literacia da leitura literária e os modos literários: estudo das actividades de leitura do livro do aluno de português da 11ª classe em Moçambique
Authors: Tachiua Brain , Sujai Calton , Balata Jerónimo Pascoal
Published: February 2025

O conceito de literacia literária constitui-se problemática dessa pesquisa, dado a forma como é explorado no livro do aluno de português da 11ª classe. Neste estudo analisa-se como se realiza a literacia literária a partir da abordagem dos comandos de leitura dos géneros discursivos literários do livro do aluno de português da 11ª classe à luz das dimensões da literacia literária. O trabalho segue uma metodologia qualitativa, subsidiada pela análise de conteúdo. Quanto aos resultados, vimos que no acto de interpretação dos textos literários, a maioria dos comandos foca-se mais frequentemente na dimensão crítica e menos nos seus pormenores extratextuais, ou seja, a dimensão cultural. Outrossim, o texto é visto nele mesmo e por ele mesmo, tomando uma perspectiva estruturalista do ensino da leitura, o que não permite a efectivação da literacia da leitura literária, mesmo que os modos literários presentes no livro do aluno sejam adequados para o efeito.
A construção assimilativa aditiva numa visão construcionista da gramática
Authors: Wiedemer Marcos Luiz Wiedemer , Moraes de Siqueira Evelyn
Published: February 2025

Neste artigo, com base na Abordagem Construcionista da Gramática Baseada no Uso (Goldberg, 1995, 2006, 2013; Croft, 2001; Traugott & Trousdale, 2013, entre outros), investigamos os contextos de uso das microconstruções ‘assim como’, ‘bem como’ e ‘tal como’ no português brasileiro. Demonstramos que essas microconstruções possuem sentidos comparativo e aditivo, sendo denominadas construção assimilativa aditiva (cf. Siqueira, 2022). A partir de uma perspectiva sincrônica, adotamos o Corpus Now, uma subamostra do Corpus do Português, para analisar 289 ocorrências de uso na modalidade escrita, considerando o período de 2012 a 2018. Os resultados gerais indicam a ocorrência de duas funções discursivo- funcionais: (i) sequenciação – na qual se encadeiam elementos em adição a alguma informação apresentada anteriormente, sendo ‘bem como’ a microconstrução que mais instanciou esse uso e (ii) exemplificação – ao instanciar elementos com a função de exemplificar uma informação apresentada anteriormente, com maior frequência de ‘tal como’.
Reflexões críticas sobre a Gramática do Português Brasileiro Escrito
Authors: Pestana Fernando
Published: February 2025

No âmbito da Historiografia Linguística — especificamente da gramaticografia (SWIGGERS, 2020), inserida no processo de gramatização (AUROUX, 1992) —, este artigo visa refletir criticamente sobre procedimentos metodológicos e contestáveis lições normativas na Gramática do português brasileiro escrito (FARACO e VIEIRA, 2023), investigando-se nela certos avanços com foco no estabelecimento duma nova norma-padrão — epistemologicamente mais afastada da tradição gramatical e centrada tão somente no português brasileiro em sua modalidade escrita formal, baseada nas linguagens jornalística e acadêmica. Para isso, cotejaram-se regras normativas estabelecidas pelos linguistas com as encontradas, sobretudo, em representativas gramáticas tradicionais da segunda metade do século XX de autores brasileiros e com dados registrados em recente pesquisa sobre a norma culta escrita do português brasileiro contemporâneo (PESTANA, 2023), a fim de atestar se a norma linguística presente nesta gramática é fruto de constatação científica ou de arbitrariedade.
Experimental Investigation of Zigzag Height Variation on the Concave Blade Surface and Its Impact on Savonius Rotor Performance
Authors: Dinata Uyung Gatot S. , Saputra Dendi Adi , Sumiati Ruzita
Published: February 2025

Clean energy offers a sustainable alternative to decreasing reliance on fossil fuel sources that significantly contribute to global CO2 emission and climate change. Wind energy extracted commonly using wind turbines has emerged as a viable and eco-friendly choice among many renewable energy sources. A Savonius rotor as a vertical axis wind turbine is especially suitable for small-scale energy generation units due to its straightforward design, economic viability, and efficiency in low wind speed areas. This report examines the impact of altering the zigzag pattern heights on the central area of the concave blade surface on turbine performance. The investigation was experimentally conducted to test the variation of such blade designs on turbine efficiency. The turbine performance parameters, including power and torque coefficients, were assessed. A conventional Savonius turbine using semi-circular blades was employed to undertake additional testing for comparison. The turbine achieved the highest power coefficient of 0.315 at a tip speed ratio of 0.8 at a wind speed of 6 m/s for turbine blades using a 2 mm zigzag pattern height. This model performed a wide range of efficiency with tip speed ratio values ranging from 0.6 to 0.8. In comparison to the conventional Savonius blades, a 26.5% increase in efficiency was observed. Consequently, this investigation has shown that the power coefficient could be substantially improved by implementing a 2 mm zigzag modification on Savonius turbine blades.

Liquid biofertilizers represent a renewable, low-cost, and effective source of nutrients for reducing chemical fertilizers, especially in short-cycle vegetables such as lettuce. The aim of the study was to evaluate agronomic variables of the crisp lettuce (Lactuca sativa L., cv. Vanda), produced using different doses of bovine liquid biofertilizer. The treatments consisted in foliar application of mineral fertilization and liquid biofertilizer, at the concentrations 0, 20, 40, 60 and 80%. The following parameters were evaluated: head diameter, total fresh mass of the aerial part, number of leaves, stem length, diameter and weight. The treatments with liquid biofertilizer showed significantly superior results compared to the treatment with mineral fertilization. The treatments with liquid biofertilizer (concentration of 20 to 80%) showed significantly superior results in relation to the treatment with conventional fertilization. By the technique of regression for quantitative variables, significant results were obtained, which indicated that the increase in the dose resulted in increment in the agronomic variables. The application of liquid bovine biofertilizer proves the possible substitution of mineral fertilizers in the cultivation of lettuce.

Authors: Bennouna Amin
Published: February 2025

For a bioclimatic villa located in Marrakech, Morocco, electricity and bills were monitored for several years in this study. Energy was aggregated into days and months to be reconciled with monthly bills. Demand-side management, namely shifting electricity consumption to the daytime, improved the investment payback time to acceptable levels. Results are used (i) to analyze financial sensitivity to self-consumption and (ii) to compare the profitability of the actual situation of the villa in self-consumption without redemption of surpluses with other possible regulatory approaches (surplus sales and net-metering).
Importance of goat milk for human health and nutrition
Authors: Kaskous Shehadeh , Pfaffl Michael W.
Published: February 2025

Compared with other types of milk, goat milk is relatively rich in valuable nutrients and offers numerous health benefits due to its high concentrations of bioactive compounds. Therefore, goat milk has been shown in various human studies to have numerous effects, such as antithrombotic, antihypertensive, immunomodulatory, antidiabetic, allergy-regulating, anti-inflammatory, antioxidant, antimicrobial, lipid-lowering, and anti-cancer properties. In addition, goat milk has a high level of monounsaturated and polyunsaturated fatty acids, a favorable nutritional profile, a buffering capacity, lower allergenicity, higher digestibility than cow milk, and potential therapeutic benefits. To increase milk production and furthermore improve the quality and food safety of raw goat milk, it is necessary to use appropriate milking procedures and goat milking machine equipment. Such beneficial measures can prevent dirt or microbial contamination of raw goat milk and subsequently lead to clean production of goat milk and colostrum preparations to prevent human diseases. In conclusion, given the importance of goat milk and the associated health benefits of its bioactive constituents, improvements in the milking process, general milking hygiene, and subsequent storage, refrigeration, and transport conditions are needed to ensure that the quality of goat milk meets the requirements for human consumption.

Background: The present study investigated the mortality of fish reared in cemented tanks in backyard farming in Meghalaya. Methods: Five dead fish and two water samples from two different tanks were brought for laboratory investigation to ascertain the cause of death. The samples (water and fish) were subjected to arrays of microbiological and biochemical tests to detect Escherichia coli, Salmonella sp., Aeromonas sp., Vibrio sp. and Listeria sp. by culture and molecular methods respectively. Result: The present study showed that all the fish samples were found to be negative for Vibrio sp. but three samples were positive for Aeromonas sp. by PCR against the genes ahh1 (130bp) and aerA (309bp) and one of the fish samples was also positive for Salmonella sp. The most Probable Count (MPN) of the water samples was not satisfactory i.e. greater than 40 MPN/ 100 ml, the content of dissolved oxygen was also low and two of the water samples were also positive for Aeromonas sp. by PCR for the same genes. Thus, from the investigation results the death of fish was inferred due to multiple factors viz. to low dissolved oxygen, very high microbial load and detection of Salmonella sp. and Aeromonas sp. Further intervention was suggested regarding optimum holding time, pH, aeration, dissolved oxygen, stocking density, clean water and feeds to control the mortality and future prevention.

Network-Independent Synchronous Stability Boundary and Spontaneous Synchronization
Authors: Yuan Yu
Published: February 2025

Synchronization of complex networks has been widely studied. Current research on the synchronization of complex networks is based on concepts from graph theory and statistical physics. However, the study of real network synchronization remains present substantial obstacles. To overcome the difficulties caused by the complexity of the network, I report a simple synchronization stability boundary equation and identify a spontaneous synchronization structure in power grids for the first time. The findings indicate that both the synchronization stability boundary and the location of spontaneous synchronization occurred are independent of the network. The boundary equation harmonizes two contradictory conclusions well and reveals the mechanism of the synchronization of different individuals through coupling. These results offer a new direction for synchronization research, providing a means to overcome the challenges posed by network complexity, nonlinearity, and uncertainty, and enabling a unified approach to analyzing the synchronization stability of grids.
Presenting Circular Gravitational Fields: A Numerical Exploration around Rotating Black Holes Second Revision
Authors: Karmiris Panagiotis
Published: February 2025

We present a novel theoretical framework, Circular Gravitational Fields (CGF), which extends general relativity by introducing a geometric coupling between a U(1) gauge field and spacetime curvature through the Ricci tensor. This coupling preserves exact consistency with vacuum Einstein equations while predicting specific modifications in strong-field regimes. Using the Baumgarte- Shapiro-Shibata-Nakamura (BSSN) formalism, we perform detailed numerical simulations to explore CGF behavior around rotating black holes and derive testable predictions for gravitational wave signatures. Our approach maintains compatibility with current observational constraints from LIGO/Virgo data while suggesting deviations that could be probed by next-generation detectors such as the Einstein Telescope.

Published: February 2025

This research addresses the problem of initial synthesis of kinematic chains with spherical kinematic pairs, which are essential in the design of spatial mechanisms used in robotics, aerospace, and mechanical systems. The goal is to establish the existence of solutions for defining the geometric and motion constraints of these kinematic chains, ensuring that the synthesized mechanism achieves the desired motion with precision. By formulating the synthesis problem in terms of nonlinear algebraic equations derived from the spatial positions and orientations of the links, we analyze the conditions under which a valid solution exists. We explore both analytical and numerical methods to solve these equations, highlighting the significance of parameter selection in determining feasible solutions. The study further investigates the impact of initial conditions and design parameters on the stability and flexibility of the synthesized kinematic chain. The findings provide a theoretical foundation for guiding the practical design of spatial mechanisms with spherical joints, ensuring accuracy and reliability in complex motion tasks. This work presents a comprehensive framework for the 3D visualization of geometric transformations and coordinate relationships using Python 3.13.0. Leveraging the capabilities of libraries such as NumPy and Matplotlib, we develop a series of modular code examples that illustrate how to plot and analyze multidimensional data pertinent to kinematic chain synthesis and robotic mechanisms. Specifically, our approach demonstrates the visualization of fixed points, such as XA, YA, ZA, xB, yB, zB, and xC, yC, zC, alongside their spatial differences with respect to reference points and transformation matrices. We detail methods for plotting transformation components, including rotation matrix elements (e, m, n) and derived products from these matrices, as well as the representation of angular parameters (θi, ψi, i) in a three-dimensional context. The proposed techniques not only facilitate the debugging and analysis of complex kinematic behaviors but also provide a flexible tool for researchers in robotics, computer graphics, and mechanical design. By offering a clear and interactive visualization strategy, this framework enhances the understanding of spatial relationships and transformation dynamics inherent in multi-body systems.

Published: February 2025

Seasonality, one of the most outstanding characteristics of tourism, is recognized as a significant challenge for regional tourism, impacting the local economies and limiting sustainable development. Among the strategies that literature suggests in order to alleviate its negative effects is the organization of events. In particular, the holding of sport events has gained recognition as an essential element for all-year round tourism development. However, a deeper understanding of how tourism practitioners (who are those that face the personal and financial difficulties of sea-sonality) perceive the potential of sport events to smooth its challenges has not yet been explored enough. This study aims to fill this gap by examining tourism practitioners’ views on the role of sport events, particularly running ones, in mitigating tourism seasonality. In-depth qualitative interviews were conducted with tourism practitioners from selected regions of Greece who, as active stakeholders, shared their perspectives in the development of regional tourism through the year round. The data gathered from these interviews was analyzed using thematic analysis. The results indicate that most of the respondents recognize seasonality as a significant challenge and they share a common concern regarding its adverse effects on both regional tourism and on their local businesses. Themes of survival and sustainability emerged consistently, emphasizing the need of implementing various initiatives, apart from sport events, to mitigate its effects. This study contributes to the broader discussion on seasonality, focusing on its economic and social impli-cations, particularly from the perspective of tourism professionals. It also provides practical recommendations for destination managers on utilizing sport events as a tool for promoting tourism during off-season periods. Finally, the findings highlight the need for localized and collaborative initiatives to address seasonality issues and support sustainable development.

Published: February 2025

Suicide is a complex health concern that affects not only individuals but society as a whole. Its prevention is possible but to be effective it has to consider the medical and technological resources available for its evaluation. Nowadays, computational advancements have enabled new forms of study of this phenomenon. Particularly, the study of suicidal ideation using computer-based techniques primarily involves two main technical approaches: text-based classification and deep learning. Furthermore, it heavily relies on creating and using custom datasets with social media textual data. However, some publications have utilized public information (e.g. records from a particular healthcare provider) in their studies. In this paper, a comprehensive overview of current advancements in automatic suicidal ideation detection, focusing on computer science techniques from 2020 to 2024, is provided. Particularly, it evaluates existing and innovative methodologies, datasets, and limitations in the field to give a proper analysis based on the PRISMA methodology of the current state-of-the-art of this specific task.
Intensity Correlation Imaging and Nonnegative Dynamic Systems
Authors: Hyland David
Published: February 2025

This work is a supplement to the the author’s “The Rise of the Brown-Twiss Effect” featured in the Photonics special issue: “Optical Imaging and Measurements: 2nd Edition". The main contribution for the author’s algorithm was the survey of the stochastic search algorithm required to determine the true noise free-image via the Brown-Twiss effect with enormously small integration times. A key element in the algorithm was the introduction of initial conditions where the values of the intensity pixels are assumed to be mutually statistically independent and uniformly distributed over the range where is a (very small) positive constant. This algorithm performed quite well, but the small initial conditions are unnecessary, as well as other complications that should be simplified. Here we streamline the algorithm in the form of a discrete-time dynamic system and explore the alternate features and benefites of compartmental nonnegative dynamic systems.
