Normalized solutions for biharmonic Schrodinger equations with potential and general nonlinearity
Authors: Zou Fengwei , Yao Shuai , Sun Juntao
Published: December 2024

We study the existence and non-existence of normalized solutions to the  biharmonic equation $$ \Delta ^2u-\Delta u+V(x)u+\lambda u=f(u) \quad \text{in }\mathbb{R}^N. $$ where \(0\neq V(x)\leq V_{\infty }:=\lim_{|x|\to \infty }V(x)\in (-\infty ,+\infty ]\)  and \(f\in C(\mathbb{R},\mathbb{R})\) is a nonlinearity. For the trapping case of \(V_{\infty }=+\infty\), under some suitable assumptions on \(f\), we prove that there exists a ground state as a global minimizer of the corresponding energy functional.  For the case of \(V_{\infty }<+\infty\), under some other assumptions on  \(f\), we prove that there exists \(\bar{\alpha}\geq 0\) such that a global minimizer exists if \(\alpha >\bar{\alpha}\) while no global minimizer  exists if \(\alpha <\bar{\alpha}\). Moreover, the size of \(\bar{\alpha}\) is  also explored, depending on the potential \(V\).

Assessment of the dynamics of the diffusion of mobile technologies in the Visegrad Group
Authors: Salamaga Marcin
Published: December 2024

The diffusion of innovation involves the spread of new solutions in the field of technology, organisation of production and marketing, as well as knowledge among enterprises-imitators, the society, etc. The aim of the research described in the paper is to assess the volume and rate of the diffusion of mobile technologies in the processing industry and to determine the nature and strength of the impact of investment specialisation (investment attractiveness) and industry export specialisation on this phenomenon in the Visegrad Group (V4) countries as a whole. The occurrence of innovation diffusion and its dynamics were examined using the econometric model of the Gompertz function. An error correction model (ECM) was used to determine the impact of V4 countries’ investment and export specialisation on the process of innovation diffusion. The ECM was estimated for selected industrial processing sectors. The study is based on data on foreign trade, innovation and foreign direct investment for the years 2010–2021 obtained from Eurostat and the national statistical institutions of Poland, Czechia, Hungary and Slovakia. The research results show that the diffusion of mobile technologies in the V4 countries occurs in various industries, but its rate varies depending on the degree of the industry’s technological advancement and the ownership structure of the enterprise capital.

Authors: Drożdż Jadwiga
Published: December 2024

The economic and financial situation of the food industry is a complex phenomenon that cannot be measured by a single financial indicator. Its assessment requires the consideration of multiple aspects, which is made possible through the construction of synthetic indicators. The aim of the study discussed in the article is to assess the economic and financial situation of the food industry in Poland from an intersectoral and dynamic perspective. Published and unpublished data provided by Statistics Poland were used to make the comparisons and calculations. Data reflecting the performance of food and beverage manufacturers in 2022 were analysed and compared to those from 2019. Subsequently, the values of the synthetic indicator were calculated. The synthetic indicator was constructed using the TOPSIS method, which is based on Euclidean distances from both the ideal and anti-ideal development patterns.
The results indicate that the economic and financial situation of individual branches of the food industry in 2022 was favourable. Compared to 2019, only minor changes occurred. This reflects the sector's high resistance to adverse macroeconomic conditions and its adaptability to operate in a volatile and unpredictable market environment. The findings also confirm the persistence of significant intersectoral variation in the economic and financial situation.

Optimizing Multiple Objectives of a Compact Solar PV-T System using the Whale Optimization Algorithm
Authors: Mutund Daddy Kalej
Published: December 2024

Solar photovoltaic-thermal (PV-T) systems enhance overall efficiency by reducing heat losses at the aperture plane and potentially increasing irradiance per unit area compared to larger prototypes. Despite these benefits, limited research has been dedicated to improving the efficiency of PV-T collectors. This study introduces a novel approach for optimizing hybrid PV-T collectors using the Whale Optimization Algorithm for multi-objective optimization. Quadratic equations describing performance metrics, such as mean electrical and thermal efficiencies, are employed to demonstrate the proposed methodology. The problem is formulated as both a single and multi-objective optimization problem, with the former revealing the conflicting nature of the objectives, thereby justifying the multi-objective approach. Optimal solutions, including parameters such as cooling water flow rate, inlet water temperature, and solar panel tilt angle, are identified and reported. Additionally, sensitivity analysis results are provided to deepen the understanding of the underlying dynamics in the multi-objective optimization process.

It was concluded and recommended that the use of pictures and images should be encouraged in the process of teaching reading, as children learn fast and better with what they see and are allowed to practice on their own.
Observar, tocar, medir y describir
Authors: Amaro Gonçalo , Costa André
Published: December 2024

Este artículo se basa en una reflexión sobre el origen y la evolución de los museos a lo largo de la Historia. Sostiene que los museos no son necesariamente el resultado de una evolución lineal desde las Cámaras de las Maravillas hasta los Museos Nacionales, sino el resultado de una amplia competencia, tanto entre diferentes entidades políticas como entre diferentes proyectos epistemológicos. Por un lado, la evolución de la ciencia y el desarrollo de la teología cristiana se combinaron en una fascinación por la acumulación y descripción de objetos. Por otro lado, la propia transformación de la Historia y la Arqueología, como disciplinas dirigidas por la cultura material, alimentó una concepción científica del Museo. De este modo, el artículo identifica una línea fundamental en el surgimiento del Museo: la protección de los objetos/reliquias, no sólo como memoria del pasado, sino como puente entre el pasado y el futuro, donde lo nuevo, lo desconocido, otras culturas y las nuevas creaciones artísticas ampliaron constantemente el universo conceptualde las Humanidades.
Del gran relato a la Posmodernidad. La descolonización de los museos
Authors: Fernández Cabaleiro Begoña
Published: December 2024

La posmodernidad tiene como principal marca la caída de las metanarrativas, dando paso a la existencia de microrrelatos, verdades mínimas adaptadas a lugares, formas de vida de pequeños grupos sociales, población marginal, grupos étnicos silenciados, al tiempo que emergen formas e identidades políticas feministas, ecologistas, sexuales, étnico-raciales, urbanas... Se trata de una crisis de las estructuras de conocimiento hegemónicas eurocéntricas y occidentalistas marcadas por un fuerte impulso anticolonial. Este proceso requiere la descolonización del pensamiento, la educación y las instituciones culturales, como el museo, que comienza a repensar tanto sus exposiciones como la presentación de sus colecciones desde esa perspectiva decolonial que promueven el ICOM y las políticas culturales. Pero en este replanteamiento podemos encontrar formas de relación entre culturas diversas que no siempre fueron formas de sometimiento, apropiación o dominación colonial.

Authors: Odusina B. O. , Ibraheem K. O. , Olaniyan H. B. , Abiola R. M.
Published: December 2024

Chassalia kolly is a shrub that belongs to the family Rubiaceae. It is used in the treatment of skin infections, typhoid and fever in traditional medicine practice. In this study, essential oil extracted from the leaves of Chassalia kolly was analyzed for its chemical constituents and investigated for antioxidant activities. Leaves of Chassalia kolly were collected at Ibadan, Nigeria's Oyo State. Hydrodistillation method was used to extract essential oil from the leaves of Chassalia kolly. Analysis using the gas chromatography mass spectroscopy technique was used to determine the essential oil's chemical composition. Using the 2, 2-Diphenyl-1 picryl hydroxyl (DPPH) radical scavenging activity technique, the antioxidant activities of the essential oil were investigated at dosages ranging from 200 to 25 μg/ml. The major constituents identified by gas chromatography mass spectrometry (GCMS) examination are curcumene (5.8%), 1,8 cineole (3.76%), nerolidol (5.48%) and α-farnesene (5.07%). Minor elements such as linalool (1.00%), caryophyllene (1.63%) and phytol (1.09%) were also found. The antioxidant test showed that the essential oil had a moderate percentage of radical scavenging activity of 18.61% when its radical scavenging activity at a concentration of 200 μg/ml was compared to the standard ascorbic acid at the same dosage. The ethnomedicinal uses of Chassalia Kolly may be due to the presence of these chemical constituents in the essential oil extracted from the leaves.
GEO-ELECTRICAL EVALUATION OF LEACHATE INFILTRATION INTO THE AQUIFER OF THE AGIRIFON DUMPSITE, ILUTITUN SOUTHWEST NIGERIA
Authors: Olabode O.O. , Olayanju G. M.
Published: December 2024

The effect of leachate infiltration from the Agirifon dumpsite to the aquifer system of Ilutitun was investigated using the Electrical Resistivity methods. The investigation was aimed at determining the geoeletric geometry of leachate plume at the subsurface of the dumpsite. Six traverses were established to cover the entire study area, Dipole-Dipole electrode configuration was employed using electrode separation of 5m and 10 m. The expansion factor n was varied from 1-5meters and 1-10meters respectively. The 2-D resistivity structures delineated virtually a single type of subsurface formation (Coastal Plain Sands) which can be divided into three zones; the topsoil or upper zone made up of sandy clay/clayey sand/sand, the intermediate zone made up of clayey sand/sand and the lower zone majorly made up of sand. The three zones generally transit into one another. The 2-D Resistivity imaging revealed a radial migration of leachate in the range 7.2Ωm in the NW/SW direction of the study area from the topsoil to a depth of 30 m beneath the dumpsite facility. The leachates were observed to have infiltrated through the porous and permeable layers into the subsurface aquifers, subsequently contaminating the underlying groundwater resource. It could therefore be concluded that the leachates produced from the dumpsite has gradually infilltrated into the subsurface (shallow and deep) aquifers in the study area.

Published: December 2024

Museums play a pivotal role in educational settings by serving as platforms for exploring history and local culture. Nevertheless, a disparity exists between national museums and their regional counterparts. Regional museums often lack comprehensive educational programming and are primarily viewed through the lens of tourism. Addressing this imbalance necessitates enhancements in educational initiatives within regional museums. However, a thorough analysis of visitor trends is imperative before implementing reforms. In this study, we focus on a museum situated on the island of Borneo, specifically in Bulungan, North Kalimantan, Indonesia, to contextualize our investigation. This study analyzed the visiting trend and educational activities at the Museum Kesultanan Bulungan in Indonesia from June to December 2022. We used a quantitative approach as a primary approach by focusing on the number of visitors and gathering qualitative information as part of validity through observations and interviews with museum managers. The study found that regular tourism visits dominated educational visits, with seasonal educational activities confined to specific months. Most visitors come from the North Kalimantan region, indicating that the museum primarily caters to the local population. However, the study also suggests the potential to expand its outreach to visitors from other regions of Indonesia and internationally. Students from senior high school, junior high school, and elementary school dominated the number of visitors engaging in educational activities, with field studies being the most common. The study provides insights into the patterns of museum visits and educational activities at Museum Kesultanan Bulungan and suggests ways to improve its outreach and educational offerings. Drawing upon the findings of our study, we propose several recommendations

Authors:   Universiti of Technology Mara (UiTM), Yusuf Noranizah , Bujang Saimi ,   Universiti of Technology Mara (UiTM)
Published: December 2024

This article aims to explain the significant role of the Hukum Kanun Lingga (HKL) in the history of Islamic law in Sarawak. The Muslim community once used the HKL as a legal reference during the reign of the Brunei Sultanate. This study employs a qualitative approach through the analysis of historical documents and legal texts, as well as philological methods, to understand the linguistic structure and legal context of the manuscript. This approach allows for an in-depth study of the development of Islamic law in Sarawak, particularly through the analysis of the original HKL text. The primary sources for this study are the HKL manuscript and previous studies related to the history of Islamic law in Borneo. The findings indicate that the HKL is a crucial document that validates the practice of Islamic law within Sarawak’s society. The HKL contains laws related to marriage, criminal justice, economics, and land ownership, which are based on Islamic Sharia principles and local customs. In conclusion, this study emphasizes that the HKL is an important document that not only highlights the practice of Islamic law in Sarawak but also played a significant role in shaping the social, cultural, and legal structure of the Muslim community during the Brunei Sultanate era. The HKL clearly integrates Islamic Sharia principles with local customs, making it a vital foundation of the legal system at that time. The findings of this study introduce a new narrative on the development of Islamic law in Sarawak, where the HKL serves as solid evidence of the existence of a structured Islamic legal system prior to the Brooke colonial era. Therefore, preserving and further studying this manuscript is essential to understanding the heritage of Islamic law in Sarawak and ensuring it remains appreciated as part of the state’s historical and cultural identity.

The family Papilionidae of butterflies, known for their striking colours and graceful flight, constitutes a significant component of tropical biodiversity. Widely distributed across various habitats, these butterflies are aesthetically pleasing and serve as important biological indicators. The natural history collection owned by the Sarawak Museum Department has been gradually expanding since the 1980s, with the samples constituting a growing archive of documented butterflies for future analyses. This study aims to document the taxonomic diversity of Papilionidae butterflies in Sarawak over the years. The study overall documented a total of 40 species of Papilionidae from the natural history collection and an extended sampling session. Chilasa paradoxa was the most abundant species recorded, while Graphium aristeus was the least abundant species recorded from the collection. The sampling session identified Pachliopta aristolochiae as the most dominant species, with twelve other species documented only once throughout the sampling period. This study provides valuable insights into the diversity and conservation significance of Papilionidae butterflies in Sarawak, underscoring the importance of museum collections as repositories of biological knowledge.

Authors: Mansurjon Sotivoldievich Boltaev
Published: December 2024

Objective: This study aims to conduct a comprehensive comparative analysis of international health insurance systems, focusing on the legal regulation of health insurance to identify strengths and weaknesses. The goal is to develop evidence-based recommendations to improve Russia’s mandatory health insurance (MHI) system, addressing issues like funding, access to services, care quality, and legal frameworks. Method: The research applies a theoretical framework built on domestic and international scholarly works related to health insurance and insurance law. The study uses general scientific methods like analysis, synthesis, and comparison, complemented by comparative legal analysis and institutional review. Empirical data are drawn from legal acts, statistical data from organizations like WHO and ILO, and case studies. Results:  The research identifies key health insurance models: state-funded (e.g., UK, Canada), social insurance (e.g., Germany, France), and private insurance (e.g., U.S.), each with distinct advantages and challenges. Global trends include an increasing role of the state in health insurance regulation and efforts to expand universal coverage. Countries are evolving from selective to universal health insurance systems, focusing on accessibility, affordability, and quality of care. Novelty: The study highlights the applicability of international models for enhancing Russia’s MHI system, focusing on expanding state regulation and ensuring universal coverage. Key recommendations include improving regulatory frameworks, addressing coverage gaps for specific groups like the self-employed and rural populations, and strengthening accountability among insurers and providers.
CERTAIN LEGAL ASPECTS OF A PROFESSIONAL ATHLETE'S CONTRACT

Published: December 2024

Objective: This study aims to analyze the legal framework governing sports contracts in Uzbekistan, identify challenges in the current regulations, and propose recommendations for improvement, focusing on the classification of sports contracts as labor, civil-law, or hybrid agreements. Method: A comparative legal analysis was conducted, examining national and international legal frameworks, including Uzbekistan’s legislation, the Civil Code of Belarus, and labor regulations in Germany, Mexico, and Chile. A doctrinal approach was employed to explore legal debates on the classification of sports contracts. Results:  The findings reveal that sports contracts occupy a unique legal space, blending elements of labor and civil-law agreements. In Uzbekistan, ambiguities persist in the “Law on Physical Culture and Sports,” which does not explicitly favor labor or civil-law contracts. By contrast, countries like Belarus explicitly recognize hybrid contracts, offering greater flexibility. Comparative analysis highlights that countries like Italy and Spain, which integrate sports-specific legislation with general labor laws, provide a balanced approach. These frameworks could serve as models for Uzbekistan. Novelty: This research contributes to the discussion by proposing the adoption of hybrid contracts as a solution to legal ambiguities. Hybrid contracts can balance the operational flexibility required by sports organizations with the social protections necessary for athletes, aligning Uzbekistan’s regulations with international best practices.

La educación para la ciudadanía comprende un campo de reflexión e intervención centrado en la premisa de que todo abordaje debe considerar a las personas participantes como sujetos de derecho, con posibilidades de participar de manera auténtica en los diversos espacios sociales en los que se encuentre, independientemente de su edad, género, etnicidad o alguna otra característica que le ponga en posición de vulnerabilidad. Entre los objetivos de esta praxis se encuentra el favorecer la convivencia democrática, la erradicación de las diversas formas de violencia, el ejercicio de derechos humanos, la participación social y la superación de formas de exclusión a través de intervenciones educativas en ámbitos formales y no formales. En este número se presentan aportaciones que apuntan al logro de esos objetivos.
Por otra parte, en la sección miscelánea se incluyeron dos artículos que abordan temas relacionados con las ciencias naturales y exactas, los cuales, al igual que en la sección temáticas, se evaluaron por pares ciegos.
In-Depth Study of Climate Change and its Impact on Terrestrial Wireless Communications over North Western Nigeria

Published: December 2024

In recent times, studies on climate change and the impact on wireless communications are gaining the attention of radio scientists and engineers for effective planning of radio link and equipment maintenance. Climate change variabilities and their implications on wireless communications over the cities of Kaduna, Katsina and Sokoto (north western Nigeria), were investigated using forty-two years’ (1980-2021) atmospheric data. Results reveal substantial degree of climate change with increase in temperature profiles for all the locations. Minimum climatic mean temperature of 27.01, 29.30 and 30.70 oC were determined in Kaduna, Katsina and Sokoto respectively. Similarly, highest mean values of 30.20, 31.80 and 32.10 oC were obtained respectively in that order. The months with the least and highest temperatures in Kaduna are December and April with 23.91 and 33.06 oC respectively. For Katsina; 25.23 and 35.76 oC were obtained, while 26.28 and 36.05 oC were obtained in Sokoto in January and April respectively; and the hottest month in the studied region is April. For precipitation, minimum mean values of 2.02, 1.19 and 1.30 mm and maximum of 5.24, 2.53 and 2.39 mm were obtained in Kaduna, Katsina and Sokoto respectively. The month with the highest amount of rainfall in all the cities is August with mean values of 8.97, 6.45 and 6.52 mm in Kaduna, Katsina and Sokoto cities. The implications of these findings on terrestrial communications are that; installed out-door communication hardware such as the transmitting tower and antenna, transmitter modules and wave guides could be subjected to perturbations that will affect their optimal performances and durability during the months of excessive temperature and rainfall. Radio scientists and engineers should incorporate climate change impacts on equipment design and employ major preventive maintenance on outdoor hardware in the months of April and August over the studied areas to ensure reliability and safe cost.
