A tal fin, se emplean herramientas estadísticas que evalúen las variaciones introducidas por cambios de temperatura, alteraciones en el voltaje de alimentación o aquellas inherentes al proceso de fabricación CMOS. Comprobamos que estas no modifican de manera significativa el funcionamiento de cada LNA ni producen diferencias entre ellos relevantes que repercutan en la correcta operación de la antena en conjunto.
El Segrià i la Franja d'Aragó. Una cartografia literària de la frontera des de l'obra de Francesc Serés
Authors: Ballonga i Montoliu Adria
Published: July 2024

Este artículo quiere tratar la representación del espacio de la frontera catalana-aragonesa en las novelas Una llengua de plom y La pell de la frontera de Francesc Serés. Escogiendo la frontera a la vez como objeto y sujeto literario, el autor construye una geografía íntima que subvierte las nociones dicotómicas de centro y periferia. Desde los márgenes, Serés hace de su escritura un documento antropológico, histórico y literario que le permite tratar temas como la pérdida de lo rural, la muerte de la naturaleza o el paisaje como ruina.
París como palimpsesto memorial en Georges Perec y Patrick Modiano
Authors: Poch Violan Esteve
Published: July 2024

El siguiente artículo pretende explorar la relación que la obra de Patrick Modiano y Georges Perec mantiene con su ciudad natal y de qué manera, lejos de anclar París a la vanguardia temporal e histórica, la representan en tanto que anacrónica. Es decir, evidencian que el espacio urbano que habitan está atravesado por una multiplicidad temporal que lo define y que no puede evitar. Así, centrándose en En el café de la juventud perdida y Dora Bruder, por un lado, se intentará exponer cómo el pasado, tanto personal como colectivo, de la Ocupación nazi de París es inseparable de un narrador que, o bien huiría de él o seguiría sus rastros por los barrios y calles de un espacio asaltado por un ambiente melancólico y onírico. Por otro, si bien la mayor parte de la producción literaria de Georges Perec tiene una clara relación con París y lo urbano, será el proyecto Lieux el que sirva de apoyo para explorar de qué manera entiende la relación con lo habitable y cómo la memoria de una infancia perdida que habita en los lugares que vive en el presente determina una topografía que satura el espacio con una multiplicidad de tiempos.

Published: July 2024

The results of evaluation of five breeding varieties of meadow clover (Trifolium pratense L.) in terms of fodder and seed productivity are presented. Breeding varietal populations of P-15, GPF-49-3, GPF-86-3 SGPF-159-3, SGPF-159-3 + SGP-117 of the double-cut type were investigated in comparison with the standard Dymkovsky for 3 years of economic use of grass stands (2020-2022) in a competitive varietal trial of 2019 sowing. The studies were conducted on strongly acidic (рНKC1 = 4,47) sod-podzolic soils with high content of exchangeable forms of phosphorus and potassium (192.5 and 217.9 mg/kg), low – humus (2.2%). The weather conditions in the years of research were characterized as moderately warm. The average monthly air temperature for April-August amounted to 13.0-15.6 °C with different precipitation supply: in 2020 – excessive, in 2021 – with a slight deficit, in 2022 – close to normal. During the years of research, high winter hardiness of all the studied varieties (more than 80%) was established. The duration of plant development periods in the varieties at mowed and seed use of grass stands was determined. The economic and biological characteristics of the varieties were given, describing the nature of the changes in plant height and foliage, fodder and seed productivity in comparison with the standard Dymkovsky. Two breeding varieties GPF-49-3 and P-15 have been identified based on the results of this research. The winter hardiness of these varieties was 92.6 and 96.9 %, total dry matter yield for 2 years – 21.90 and 21.56 t/ha (+12.7 and 11.0 % to the standard) and the seed yield on average for 2 years – 1.72 and 2.14 kg/ha (+8.9 and +35.4 % to the standard). These varieties are promising for testing in the Volga-Vyatka region and are suitable for state variety trials.
Some Approximate Division and Semigroup Identities for the Mittag-Leffler Function
Authors: Clemence-Mkhope D.P. , Denton Zachary
Published: July 2024

It is known that the Mittag-Leffler (ML) function, Eα(z), a non-local extension of the Euler exponential function ez, does not enjoy the semigroup property while ez does. The purpose of this note is to show that Eα(z) does, however, for real t, s with s small enough, enjoy the approximate semigroup property, Eα(t+s)≈Eα(t)(1+Eα,α(t)/Eα(t))s. This follows from an approximation of limh→0+Eα(±(u+h)α)/Eα(±uα) , which also yields related expressions for α→1−, and is obtained from a recently proposed universal difference quotient representation for fractional derivatives. Graphical demonstrations are presented to show that the approximations are 'reasonably accurate' for 0h≤0.1, with virtually no distinction from identity for 0h≤0.01.

Auction-Based Distributed Task Allocation Algorithm for Drone Swarms
Authors: Eşer Mutullah , Yılmaz Asım Egemen
Published: July 2024

Research on drone swarms has gained traction in recent times due to their ability to outperform single drones in various tasks. In order for autonomous drone swarms to carry out tasks effectively, it is crucial that the tasks are distributed among the drones. This poses a considerable challenge that must be addressed in the advancement of drone swarm technology. The assignment problem is basically defined as the process of assigning M tasks to N drones in a way that minimizes the total cost. This paper presents an auction-based distributed task allocation algorithm called Harmony DTA (Drone Task Allocation) for heterogeneous drone swarms. Prior research primarily focuses on minimizing overall costs associated with assignments. In contrast, Harmony DTA not only minimizes total costs through an enhanced cost calculation function, but also ensures equitable distribution of workload among drones. Additionally, the proposed two-stage auction process reduces the total message size utilized during communication. Matlab simulations and field tests were conducted to assess the effectiveness of the proposed algorithm. Moreover, the algorithm's performance was evaluated in comparison to the CBBA (Consensus Based Bundle Algorithm). The results obtained indicated that the proposed algorithm is capable of assigning tasks with high efficiency, without encountering conflicts.
Mulheres Cientistas nos Livros Didáticos de Ciências do Brasil no Século XXI
Authors: Fernandes Hylio Lagana , Costa Angélica Felício
Published: July 2024

A ciência moderna foi historicamente estabelecida como atividade masculina, concepção mantida até o século XX, a despeito da crescente participação das mulheres nas atividades científicas. Considerando a importância dos livros didáticos na educação escolar, este trabalho investiga como os livros didáticos de ciências apresentam as mulheres nas ciências no recorte temporal 1980–2022. Foram contabilizadas em coleções didáticas de três grandes editoras brasileiras todas as citações textuais e imagéticas de mulheres e homens cientistas, e analisadas via semiótica peirceana as imagens das cientistas mulheres. Resultados apontaram incremento nas referências de mulheres cientistas a partir dos anos 2000, porém sempre em número muito menor que as citações de homens. A análise semiótica das imagens permitiu identificar quatro categorias de representação de mulheres cientistas: reais (imagens de cientistas devidamente identificadas); anônimas (fotografias sem identificação); fictícias (representações figurativas de personagens criadas) e ocultadas (imagens fotográficas/pictóricas de cientistas reais sem identificação nominal). Cerca de metade das imagens situa-se na categoria reais (49%); as demais distribuem-se em: anônimas (31%), fictícias (15%) e ocultadas (5%). Apesar da crescente presença de mulheres cientistas nos livros didáticos do século XXI, o baixo número de citações, assim como as formas como são apresentadas, colabora para a manutenção da concepção masculina da ciência.

Abstract
Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on red carotenoid‐rich Paracoccus carotinifaciens NITE SD 00017 for salmon and trout (category: sensory additives; functional group: colourants; substances which when fed to animals add colours to food of animal origin) for the renewal of its authorisation. The applicant provided evidence that the additive complies with the conditions of the authorisation. The Panel concludes that the use of the additive in salmon and trout remains safe for the target species, the consumer and the environment under the authorised conditions of use. When assessing consumer exposure to canthaxanthin and adonirubin at the level of the existing maximum residue limits (MRL) for poultry and the proposed MRL for trout/salmon (5 mg/kg muscle), the exposure of consumers exceeds the acceptable daily intake (ADI) in the population classes toddlers and other children. The Panel considers that there is no need to restrict the use of the additive to fish older than 6 months or of more than 50 g. Red carotenoid‐rich Paracoccus carotinifaciens NITE SD 00017 is not irritant to the skin, but is irritant to the eyes. It is considered a dermal and respiratory sensitiser and any exposure via skin or the respiratory tract is a risk.

Authors: Roldán-Mora Natalia Andrea , Cárdenas-Claros Mónica Stella
Published: July 2024

This systematic review investigates learner use of audio/video playback (AVP) controls in technology-enhanced listening environments. To this aim, 61 academic works produced from 2000–2021 underwent inclusion/exclusion criteria and were analyzed. The resulting corpus was made up of 16 peer-reviewed articles. We first situate the studies examined with regards to contextual, educational, and methodological characteristics of AVP controls research.  Then, we conducted thematic analysis to identify, analyze and report affordances and limitations of AVP controls. Four affordances and two limitations were identified. The affordances describe how AVP controls enable students to resort to different strategies, change their interaction patterns with learning materials, address comprehension problems and enhance listening comprehension performance. Similarly, limitations describe how proficiency level restricts interaction with AVP controls and the need for learner training on AVP buttons. Results are discussed along with integrated data.  Pedagogical implications and avenues for further research are also discussed.

Authors: Felismonte Isidra , Donn Donn Enrique , U Ruiz Merle
Published: July 2024

The field of education for sustainable development advocates for new teaching methods that offer hands-on, engaging, and transformative learning experiences that encourage critical and systemic thinking within the framework of sustainable development. Higher education institutions strive to support the attainment of SDG 4 by promoting inclusive, fair, and high-quality education. Service-learning in higher education is in tune with the educational principles of critical and transformative pedagogy and facilitated through implementation of innovative pedagogical approaches in training professionals that will be socially critical and committed to social transformation, with the goal of achieving a larger social justice. Consequently, one of the major challenges attributed to the lack of social practice and community service in the learning environment leads to the detachment of students to the community, as well as the low social responsibility among the undergraduates. The study aimed to fill the research gap in the literature on  the impact of service-learning pedagogies among students based on knowledge, attitude, and spirit and how it is correlated with professional development, personal development, social transactions. Furthermore, this study highlights how civic engagement and sustainable community development, the integral components of service-learning, contribute to and align with the principles of sustainable tourism. By connecting these elements, the research emphasizes the multifaceted benefits of service-learning in shaping socially responsible professionals and fostering sustainable tourism

Authors: Negrebetsky V. , Agarkov N. , Shmarova D.
Published: July 2024

Coronavirus infection brings an extreme threat to older people and particularly to patients with severe cardiovascular pathology, including coronary heart disease (CHD). Recovery in these patients largely depends on the severity of cytokine disorders in the acute phase of the disease, since they negatively affect cardiomyocytes, including those through the development of complications in other organs and systems. However, changes in the plasma cytokines of elderly patients with CHD who have experienced COVID-19 have not been studied in practice. Objective. To study the correlations of plasma cytokines in older patients with CHD in the early recovery stages after COVID-19. Subjects and methods. The investigation enrolled 40 elderly patients with CHD at weeks 3-4 following recovery from COVID-19 and 38 patients of the same age with CHD without COVID-19 in their history. The fasting plasma cytokine level was determined using a Becton Dickinson FACS Canto 2 apparatus (USA) in the morning. The relations between the cytokines were studied by the correlation method. Results. Interleukin (IL)-6 showed the greatest number of significant correlations (direct weak and medium associations with other cytokines), including a direct statistically significant average correlation with IL-17 (r=0.63), tumor necrosis factor-α (TNF-α) (r=0.42), interferon-γ (IFN-γ) (r=0.39), IL-2 (r=0.35), IL-3 (r=0.33), as well as a weak significant relationship to IL-7 (r=0.29). IFN-γ had three direct significant correlations with IL-6 (r=0.39), IL-7 (r=0.36), and TNF-α (r=0.29). The latter showed two direct average significant correlations with IL-6 and IL-17. Conclusion. In the early stages of recovery, in 60–74-year old patients with CHD after experienced COVID-19, IL-6, IFN-γ, and TNF-α cytokines had the greatest conjugacy, which can be used as markers of recovery in this patient cohort.

Authors: Ogweno Jeremiah Okeyo
Published: July 2024

The recent advancements in satellite networks have garnered significant interest due to their extensive geographic coverage and flexible deployment capabilities, offering a promising solution for global communications and transforming traditional communication methods. Despite these advancements, current satellite systems face challenges such as high propagation delays and inadequate coverage of high-latitude regions, particularly in Geostationary (GEO) systems. Low Earth Orbit (LEO) systems, which can address these issues, are primarily used for voice services, as seen in the Iridium system, but have encountered financial difficulties. This study aims to address the security issues in satellite networks, a critical concern as these networks increasingly rely on IP protocols and hybrid configurations of terrestrial nodes and satellite links. Previous works have identified various potential security attacks on satellite networks and proposed different solutions, but these solutions often lack comprehensive effectiveness and robustness. Our methodology involves analyzing the security vulnerabilities in satellite networks similar to the Iridium system, which includes inter-satellite links (ISL) and routers on each satellite. We review and evaluate existing security measures and propose enhancements to improve their effectiveness. Our results indicate significant vulnerabilities in current systems, but also show that with targeted improvements, security can be substantially enhanced. The implications of this study are profound, suggesting that more secure satellite networks can better support critical global communications and services, including broadband Internet and data services, thereby enhancing their reliability and user trust

Background: Schizophrenia is a complex illness, in other words, requires certain costs to tackle the challenge. However, the use of psychotropic medicines is paramount for the disease management and the costs of these medications should be considered in the management especially in low- and – middle income countries. There is over-reliance on out-of-pocket payments among the individuals in these countries whereby a large number of the patients purchase the medicines out of pocket, and majority unable to afford the medicines for their illness. Aim: The aim of this study was to assess the costs and affordability of psychotropic medicines for management of Schizophrenia. It specifically evaluated the financial burden of out-of-pocket payment to purchase medicines for patients with Schizophrenia in Nigeria. Method: The study was conducted in a Neuropsychiatric Hospital in Southeastern part of Nigeria using a retrospective, cross-sectional study of the costs of psychotropic medicines for adult patients with Schizophrenia that visited the hospital. Results: All the prescribed oral typical antipsychotics (except chlorpromazine 200mg/day and 300mg/day) gave the patients less than one day wage to pay for medicines, whereas, all the oral atypical antipsychotics gave the patients more than one day wage to pay for the psychotropic medicines. Conclusion: The atypical antipsychotics were unaffordable to the patients. We considered various factors as limitation and recommend interventions for reimbursements or make the psychotropic medicines free for the patients.
Characterization of embankment material using sand tire mix as additive and validating the results obtained from large scale direct shear test in Abaqus software
Authors: Anwar Muhammad  , Rawid Khan
Published: July 2024

Laboratory direct shear tests often overlook larger particles due to limitations in shear box design, resulting in an inadequate portrayal of real-world soil conditions. To address this gap, the use of large-scale direct shear apparatus capable of accommodating larger particles is essential. However, conducting such tests with varied sizes of tire shreds, mixing ratios, and loads is intricate and resource-intensive. Therefore, the utilization of numerical modeling is suggested to simulate sand-tire mixtures under diverse conditions. This study presents conclusions derived from comparing numerical results with experimental observations, demonstrating a close correspondence between the two. It offers a comprehensive examination of the impact of sand and shredded tires mixtures on shear strength, indicating a consistent pattern: increased quantities of tire shreds correspond to heightened friction angles. Furthermore, specimens containing larger shredded tire particles display elevated friction angles, implying a possible connection between particle size and frictional behavior. This investigation underscores the importance of numerical modeling as a cost-efficient and effective approach to complement experimental inquiries, enriching our comprehension of soil-tire mixture dynamics and guiding practical applications in transportation and geotechnical engineering.
