Authors: TANDJIGORA Amadou , SY Thierno Bachir , BADIANE Sidia Diaouma
Published: November 2024

Mots-clés : COVID-19, Psychosociologie, Analyse des correspondances multiples, Agglomération, Dakar Résumé L’objectif de cet article est d’étudier l’état psychosociologique de la population dakaroise vis-à-vis de la COVID-19. Le traitement des données collectées grâce à l’outil Kobotoolbox dans les 19 communes du département de Dakar a mobilisé une analyse descriptive et une analyse factorielle des correspondances multiples. En effet, 97% des enquêtés connaissent la maladie et le tiers (33%) des répondants, affirme avoir connu une personne infectée par le virus. Néanmoins, le degré de connaissance de cette maladie implique l’adoption de comportement préventif ou non. Par conséquent, 1/3 des enquêtés soit 34% a évité les hôpitaux, par peur d’être contaminé, tout en ayant besoin d’y accéder pour soigner d’autres maladies. L’analyse par correspondance multiple a permis de catégoriser la population d’étude en trois (3) principaux groupes. De façon spécifique, un premier groupe a réuni tous les individus qui sont d’accord sur les idées reçues. Ils sont concentrés principalement dans la commune de Colobane-Fass-Gueule Tapée. Le deuxième groupe est constitué par les individus qui sont en désaccord avec les idées reçues. Ils sont localisés dans les communes de Gorée, Dieupeul Derklé, Sicap Liberté et Patte d’oie. Le dernier groupe est composé des informateurs ayant préféré la neutralité dans leur réponse. Ils sont repérés dans les communes de Mermoz Sacré-cœur, Fann - Point E - Amitié et Médina.

En second lieu, comment cette réappropriation des idéologies éthico-sociales des subalɓe à travers leurs faits et gestes participent-ils à la valorisation d’une identité patrimoniale et à l’instruction des jeunes aux dépens de tout ce qui provient de l'extérieur, symbolisant la modernité.
Enseigner la critique littéraire en Master : quand le support de cours poétisé favorise la rétention mémorielle de l’étudiant et l’installation d’autres compétences
Authors: SARR Diokel
Published: November 2024

Mots-clés : Histoire littéraire, support de cours poétisé, mnémotechnique, critique-aimant, Mémoire, auteur Résumé La présente étude, qui porte sur un cas pratique en enseignement-apprentissage, se déroule en deux mouvements. Le premier fait découvrir une méthode pédagogique appelé le support de cours poétisé. Ce dernier permet à l’enseignant, faisant un cours en Master (1 ou 2), d’user de la brièveté propre au discours poétique pour faciliter la rétention mémorielle des étudiants. Le cours dispensé porte sur la critique littéraire, précisément sur l’Histoire littéraire. C’est donc l’occasion d’installer d’autres compétences afférentes au travail du Mémoire de Master. L’approche se montre donc englobante. Le deuxième mouvement explique ladite méthode d’apprentissage en misant surtout sur les rapports de ressemblance et de dissemblance que ladite méthode critique entretient avec les autres critiques. Il y est aussi question de la centralité de l’étudiant, conformément aux exigences des méthodes d’enseignement actuelles.

In order to systematically evaluate the innovation and entrepreneurship abilities of college students, it is necessary to construct a comprehensive index system. In finance and economics colleges, students have unique abilities in innovation and entrepreneurship, such as keen market observation skills, rich knowledge of enterprise management and finance, etc. Therefore, based on research data from finance and economics colleges, we explore and construct a objective, and specific index system for college students' innovation and entrepreneurship abilities, providing a scientific basis for evaluating and enhancing their innovation and entrepreneurship abilities.
Battling to save the soul of higher education in Africa: attacks on intellectual labour in Nigeria
Authors: Arowosegbe Jeremiah O.
Published: November 2024

Violations of academic freedom are on the increase in Africa and are attracting organised resistance from academic unions across the continent. Africa has one of the worst records of attacks on academic practitioners in the world. In the early post-independence period (the 1960s and 1970s), these took the form of the politicisation and state control of the academies. In the 1980s and 1990s, the context was defined by the impact of the contradictions in the character and nature of the state, the crisis in its political economy and the role of international financial institutions and local elites. The present context is characterised by state repression and by resistance from academic unions. The resultant crisis is connected to the economic hardships experienced by the general population and the neglect of universities. This plays out in tense relations between most state officials and the universities.

Authors: Mohammed T. N. , Oyewumi K. J. , Akanbi T. A.
Published: November 2024

One of the most crucial procedures in quantum information is quantum teleportation. Quantum teleportation, which makes use of the physical resource of entanglement, is a fundamental primitive in many quantum information tasks and is a crucial component of quantum technologies. It is essential to the ongoing development of quantum networks, quantum computing, and quantum communication. Here, the practical applications of Bell states, algebra of entanglement, and quantum dense coding are highlighted. The fundamentals of quantum entanglement are described, along with its characteristics and the Einstein-Poldolsky-Rosen dilemma. By separating its distinctive properties, this paper demonstrated that teleportation will be used practically for quantum key distribution in the very near future. It also revealed the fundamental theoretical concepts behind quantum teleportation.

Authors: Daniel Ikechukwu , Akinyemi Lateef , Udekwu Obianuju
Published: November 2024

Landslides pose significant threats to life, property, and infrastructure. This study explores applying unsupervised learning techniques to identify and understand landslide-prone areas. We analyzed topographic data by employing K-Means, Hierarchical Clustering, Spectral Clustering, Mean Shift Clustering, and DBSCAN to uncover hidden patterns in landslide occurrence. Evaluation metrics, including the Silhouette Score, Davies-Bouldin Index, and Calinski-Harabasz Index, were used to assess the performance of these algorithms. Hierarchical Clustering achieved the highest Silhouette Score of 0.635, indicating excellent cluster separation. However, Mean Shift Clustering outperformed the other methods with a superior Davies-Bouldin Index of 0.603 and the highest Calinski-Harabasz Index of 4121.75, demonstrating the best overall clustering performance. DBSCAN also performed well, with a Silhouette Score of 0.610 and 12 noise points identified. These findings contribute to a deeper understanding of landslide spatial distribution and can inform the development of effective early warning systems and mitigation strategies.
Conjunctive Water Management
Authors: Evans Richard , Hanson Randall
Published: November 2024

The sustainability of water resources for water and food security largely depends on the successful adoption of conjunctive water management (CWM) strategies; it is also inherently tied to supply-and-demand management and the related external drivers of population, land development, and climate. Thus, water resource sustainability requires a holistic union of technical analysis, monitoring, and governance that is funded and maintained by all users of the resources. Accordingly, the collective management via CWM of surface water, groundwater, precipitation, and recycled, imported, and reused water will require changes in governance. The authors explore these requirements and present examples to illustrate how—through analysis and governance—these principles are put into action. However, the authors argue that monitoring and analysis are essential, yet insufficient, for the sustainability of water resources. They posit linkages to governance and funding are necessary to facilitate and maintain a sustainability framework and the mechanisms required for adapting and mitigating a sustainability strategy that uses CWM as one of its components.

Published: November 2024

In recent years, China has faced challenges such as energy shortages and environmental pollution. Metal oxides, as biocatalysts, offer promising solutions for biomass energy conversion by enhancing biochemical reaction rates, reducing energy consumption, and improving biomass conversion product quality. This study focuses on using metal-based biocatalysts in the pyrolysis of tobacco, a key cash crop. We prepared aluminum/calcium composite molecular sieves through extraction, calcination, and acid leaching of metal ores. These biocatalysts optimized the tobacco pyrolysis process, improving the composition of bioactive components in the products. Results showed that metal oxide composites effectively facilitated the cleavage and reorganization of tobacco biomolecules, influencing the structure and composition of pyrolysis gases. The presence of alkali metals led to earlier cleavage of tobacco at lower temperatures and increased pyrolysis gas concentration. Specifically, calcium or aluminum increased total weight loss in the 100–300 ℃ range while decreasing maximum weight loss, leading to higher concentrations of low-temperature pyrolysis gases. The optimal catalyst-to-tobacco mass ratio was 2:1 at 500 ℃, maximizing nicotine content, reducing ester formation, and enhancing hydrocarbon biosynthesis. This low-temperature pyrolysis method efficiently releases aroma substances and improves smoke concentration. It offers a practical approach for biomass energy conversion and bioactive substance extraction, providing new insights into metal-based biocatalysts’ role in complex biomass systems.

A comparative analysis was performed for evaluating thermodynamic properties of a number of condensed and gas-phase compounds formed in the Me-Si-O, (Me = Al, Ba, Pb, Fe, Cr, Fe, Ni, Mn, Mo), Fe-Cr-B and Fe-Si-B systems, including those with impurities of oxygen, manganese, nickel, molybdenum and aluminium, and in some systems used for coatings production. The data on the enthalpies of the formation and on the coefficients of 1 ÷ 7 equations for the calculation of the temperature dependences of isobaric-isothermal potential, entropy and heat capacity for 84 compounds were obtained. The results of the comparative correlation analysis of thermodynamic properties for a number of condensed and gas-phase compounds formed in the Me-Si-O, (Me = Al, Ba, Pb, Fe, Cr, Fe, Ni, Mn, Mo) and Fe-Cr-B, Fe-Si-B systems, including those with impurities of oxygen, manganese, nickel, molybdenum and aluminium, and in some systems used for coatings were obtained. The correlation dependences of thermodynamic properties had a multiple correlation coefficient – R = 0.98 and standard deviations for heat capacity σ ~ 4.8 % (for gas-phase compounds σ ~ 0.6 %), entropy σ ~ 5.8 %, the enthalpy of formation σ < 8 %, oxide systems σ ~ 3 % and silicates σ ~ 2 %. As a result, the enthalpies of formation and 1 ÷ 7 – coefficients of the equations for calculating the temperature dependences of isobaricisothermal potential, entropy and heat capacity for 84 condensed and gas-phase substances were estimated. The obtained thermodynamic data were tested in the thermodynamic analyses of the formation of compounds in various systems and showed satisfactory agreement with experimental results.

The paper presents the results of the studies of flammability and smoke formation of reinforced materials based on glass fiber Т-15(P)-76(92) and ED-22 epoxy resin without additives of flame retardants and with the addition of phosphorus-containing flame retardants DOPO-THPO (9,10-dihydro-9-oxy-10-phosphaphenanthrene-10-oxide-trihydroxy-methyl-phosphine oxide) DOPO-DDM (6,6′-((methylenebis(4,1-phenylene))bis(azanedyl))bis(6H-dibenzo[c,e][1,2]oxaphosphinine 6-oxide))), graphene and their combinations in concentrations from 2 to 9.98 %. The mass fraction of a binder in GFRER was 31±1 wt.% and 50±1 wt.%. To assess the flammability of the samples, the Limiting Oxygen Index, UL-94 HB, Vertical Bunsen Burner (VBB), Cone Calorimeter tests, and the Controlled atmosphere pyrolysis apparatus with a gas analyzer were used. The sample with the addition of 4 % graphene demonstrated the lowest rate of thermal decomposition, while the sample with the addition of 4 % DOPO-THPO had the lowest total heat release during combustion in a cone calorimeter. The addition of a mixture of graphene and DOPO-THPO resulted in a synergistic effect of these additives on the fire resistance of glass-reinforced composites. In contrast, all flame retardant additions led to an increase in the amount of smoke produced. For 2 % and 4 % graphene addition, as well as for 2 % DOPO-THPO addition, the increase in the smoke formation was 8-9 %, and for other compositions it was much greater. Thus, the results of the flammability tests and the smoke formation do not correlate with each other. Additions of the studied flame retardants lead to incomplete combustion, which is characterized by an increase in the amount of carbon monoxide (II) released during the combustion relative to the final combustion product CO2, that is, an increase in the smoke toxicity. It is found that DOPO-THPO as a flame retardant acts in both the gas and condensed phases however, it also leads to an increase in the formation of smoke and carbon monoxide. The addition of graphene leads to the strengthening of the carbon residue, but has a lesser effect on the toxicity of combustion products.

The paper presents a numerical simulation of the glass transition process under conditions of rapid quenching with unsteady heat transfer and fixed gradient cooling rate. A temperature-dependent form of the previously proposed theoretical model was used. This model combines the gauge theory of glass transition, assuming the presence of topologically stable defects in the forming solid phase, and diffuse heat transport. Presented results show that the proposed model is able to simultaneously reproduce the competition between crystallization (formation of a polycrystalline structure) and the formation of an amorphous disordered structure. At the relatively slow cooling rates corresponding to the formation of a crystalline phase, a transition from the columnar crystal to the equiaxed one was observed. This is qualitatively consistent with the effects observed in many metal alloys. The moving interphase front follows the equilibrium isotherm corresponding to the temperature of the phase transition in the vector gauge field subsystem. The front drag leads to the effect of kinetic undercooling and the appearance of the maximum velocity of the crystallization front. A criterion is given for the change of the solidification mode from crystallization to amorphization when the limiting cooling rate is reached.

The pulsed laser deposition (PLD) method is widely used in the production of different thin films. PLD has several advantages: flexible adjustment of parameters and controllability of processes and ease of synthesis of materials. The deposition of zinc oxide droplets during the synthesis of zinc oxide thin films by PLD is considered and the temperature and initial speed of droplets, which can boil on the thin film surface, are determined. The study of the process of the deposition of droplets from a ZnO target was carried out during the growth of thin films according to the traditional scheme for the PLD method. The process of the deposition of ZnO droplets during the PLD of ZnO films under vacuum conditions is considered. For the first time, it has been revealed that ZnO drops are boiling on the thin ZnO film surface. For the first time, the temperature and speed of solid and liquid drops of ZnO, at which they can boil when they hit the substrate, have been calculated taking into account the processes of heat loss through radiation and the heat of phase transition. Thus, for the first time, it has been established experimentally and confirmed in calculations that at the moment of collision some drops of ZnO are boiling. The role of the heat of phase transition and heat loss due to radiation during the flight of droplets during the PLD of ZnO thin films in a vacuum has been clarified. The temperature of a ZnO drop after a collision with a substrate was calculated in a wide range of initial speed and temperature taking into account heat losses due to radiation and heating from impact.
Conformational structure of polyampholytes on the surface of a spherical metal nanoparticle under simultaneous exposure to static and alternating electric fields
Authors:   Orenburg State University, Kruchinin Nikita Yu.
Published: November 2024

The simultaneous effect of external static and alternating electric fields on the composite nanosystem "gold spherical nanoparticle-polyampholyte" was studied. Radial and angular dependences of the polymer density were constructed, including in a narrow surface layer of the nanoparticle. In the case where the amplitude of the alternating dipole moment of the nanoparticle significantly exceeded the value of the static dipole moment, a ring-shaped fringe was formed in the equatorial region of the spherical gold nanoparticle. With an increase in the amplitude of the alternating electric field, the shape of the polyampholyte fringe changed from elongated in the direction of static polarization to swollen in the equatorial region of the nanoparticle. Oppositely charged links were located on those halves of the spherical nanoparticle relative to the equator, where opposite charges were induced due to the effect of the static electric field.
Comparison of calculated and practical parameters for the removal of copper ions in the form of hydroxocompounds from spent electrolytes
Authors:   Udmurt Federal Research Center UB RAS, Shumilova Marina A.
Published: November 2024

Currently, the most common methods for cleaning spent galvanic solutions from heavy metals are reagent methods based on the deposition of poorly soluble hydroxides. The paper presents the results of the thermodynamic calculation of the minimum solubility and the corresponding pH range of copper hydroxide compounds formed during the precipitation of metal ions in the industrial waste from galvanic production using solutions of sodium hydroxide and sodium bicarbonate. A laboratory experiment was carried out for finding optimal conditions for the deposition of copper from spent acidic sulfuric acid electrolytes of copper plating using 10% solutions of sodium hydroxide and sodium bicarbonate. It has been established that experimental and calculated data are in satisfactory agreement in determining the optimal pH value for the precipitation processes of copper hydroxyl compounds. It is found that there are discrepancies between the calculated and found indicators of the minimum amount of metal ions in solution, which differ for the reagents under study. It should be noted that these indicators differ from each other significantly less compared with the usual use of the solubility product as the main characteristic of the precipitation process. Therefore, when setting the task of determining the optimal precipitators for heavy metal ions in an aqueous medium, the proposed mathematical formulas can be used as guidelines for obtaining the process parameters close to the real values.
The Mechanisms for Employing Artificial Intelligence in Saudi Journalisms and its Impact on the Development of Journalistic Content
Authors: Almania Ali Mohammed
Published: November 2024

This study examined the mechanisms of employing artificial intelligence in the Saudi press and its implications for the development of journalistic content. It aims to identify the extent to which artificial intelligence techniques are employed in the Saudi press, the most prominent techniques used, measure the extent of journalistic leaders’ awareness of the role of artificial intelligence techniques in the development of journalistic content, and reveal the most important Challenges facing the use of artificial intelligence techniques in Saudi journalism, and how to overcome them.  The importance of the study is highlighted by the fact that it examines the extent to which Saudi newspapers keep up with modern technologies to develop their journalistic content, and the extent of clarity of vision among Saudi press leaders regarding artificial intelligence technologies, and their importance in media transformation, especially in light of the technical challenges and rapid developments in the media industry.  The researcher relied on the survey method to monitor the opinions of journalistic and technical leaders in the newspapers of the study sample through in-depth, unstructured interviews, to obtain deeper knowledge about the variables of the study.  The study concluded that the use of artificial intelligence techniques in the Saudi press is very limited, and thus its weak reflection on the development of journalistic content. The results of the study revealed that there is a disparity in the level of awareness and knowledge of the role of artificial intelligence techniques in journalistic work, among editors-in-chief on the one hand, and between editors-in-chief and technology managers on the other hand, in addition to the lack of a clear vision and future strategies for Saudi press institutions in benefiting from artificial intelligence, which created a gap between the content presented in these newspapers and what the public is looking for. Moreover, the results of the study also showed that there are many challenges facing the use of artificial intelligence techniques in the Saudi press, the traditional way in which Saudi newspapers operate the inefficiency of applications in supporting the Arabic language, and the danger of fake information.
Legal Protection of Notaries in Document Validation through Technology-Based Systems: A Comparative Legal Review of Indonesia, the United States, the Netherlands, and Australia
Authors: Nazran Fina , Purba Hasim , Saidin O.K. , Kaban Maria
Published: November 2024

This paper examines the legal framework and challenges notaries face in adopting technology-based systems for document validation in Indonesia, with a comparative analysis involving the United States, the Netherlands, and Australia. Indonesia's legal framework, particularly Law No. 2 of 2014 on the Office of Notary, has yet to fully accommodate electronic signatures and remote notarization. The requirement for in-person meetings for authenticating notarial acts creates a regulatory barrier to implementing cyber notary services. Furthermore, Indonesian notaries face limited access to essential data systems, such as Dukcapil (Civil Registration Directorate) and BPN (National Land Agency), complicating the verification of personal identity and property documents. In contrast, the United States has adopted e-notary systems, using blockchain technology to ensure data integrity and mitigate fraud risks. The Netherlands provides an integrated platform, allowing notaries to validate documents remotely by accessing national databases in real time. Meanwhile, Australia has implemented a Digital Identity Program to facilitate efficient online authentication of documents. These innovations demonstrate how interoperability, regulatory flexibility, and digital literacy can enhance notary services and legal certainty. This paper proposes regulatory reforms in Indonesia, including revising existing laws to support remote notarization and electronic signatures. Second, developing integrated data platforms for real-time access. Third, providing training programs for notaries to adopt new technologies and ensure data security. By aligning Indonesia’s legal framework with international best practices, cyber notary services can enhance efficiency, security, and legal protection for both notaries and the public, meeting the demands of the digital era.Comparison

Steel pipes remain the preferred choice for distribution and crude oil installation pipes in the oil and gas industry due to their strength, surface hardness, and cost-effectiveness. However, their susceptibility to corrosion in harsh environments poses significant challenges. This research focuses on analyzing the corrosion rate of API 5L X-42 steel in a crude oil environment at a temperature of 40°C. The corrosion rate was determined using the weight loss method, revealing that the rate varies over time. The findings of this study provide crucial insights for the industry, particularly in preventing leaks in crude oil installation pipes caused by corrosion. By understanding the corrosion behavior of steel pipes under specific conditions, the oil and gas industry can implement more effective maintenance strategies and material selection, ultimately enhancing the safety and longevity of pipeline infrastructure. The study highlights the importance of regular monitoring and the adoption of preventive measures to mitigate corrosion-related issues, thereby ensuring the continuous and safe operation of oil and gas installations

The creative economy has become a strategic sector in supporting economic growth in the digital era. This research aims to explore the opportunities and potential of the creative economy through digitalization and the challenges faced in developing this sector. This study uses a qualitative study method, with in-depth interviews and observations as data collection techniques to explore the experiences, strategies, and obstacles faced by business actors. The results show that digitalization plays an important role in expanding market reach, improving operational efficiency, and driving innovation. Business actors utilize e-commerce, social media, and digital applications to promote creative products and interact directly with consumers effectively. However, this success still faces challenges, including limited internet infrastructure and low digital literacy among small and medium business actors. Appropriate policy support and increasing digital literacy are key in overcoming these obstacles. This research concludes that with collaboration between the government, the private sector, and the community, the creative economy in Indonesia has great potential to become a key pillar of sustainable economic growth and strengthen competitiveness in the global market.
LA DESPOBLACIÓN RURAL Y SU METÁSTASIS A LAS CIUDADES: UNAS BREVES REFLEXIONES SOBRE SU TRATAMIENTO DESDE LA ADMINISTRACIÓN PÚBLICA
Authors: García García Sara
Published: November 2024

Desde que la cuestión del abandono de los territorios rurales se reintrodujo en la agenda de las políticas públicas nacionales y europeas, se han producido decisiones y normas que parecen caminar hacia un enquistamiento del conflicto entre los intereses de la población que permanece en las áreas olvidadas y los intereses de otras políticas fuertemente ancladas en las estrategias a largo plazo. Normas y decisiones estratégicas que colisionan con territorios y comunidades a las que se impone un decrecimiento o un conjunto normativo que hace imposible el desenvolvimiento de actividades tradicionales y su adaptación a los nuevos tiempos. En este contexto, los ciudadanos de las áreas lejanas (o, en terminología popular en España, «vacías») que observan cómo son otros intereses los que prevalentes frente a sus demandas, se enfrentan conflictivamente con una marea de normas «ajenas», impuestas, vividas como «imposiciones» que necesariamente generan conflicto, justamente cuando parecía que la discriminación positiva en favor de sus condiciones particulares se habría paso en el contexto de la «Estrategia Europea a largo plazo para las áreas rurales». Dar cuenta de estos conflictos, balancear los intereses particulares de los territorios con los grandes objetivos estratégicos y reivindicar la importancia de mantener la senda que aboga por la revitalización de las áreas rurales, es el objetivo de esta obra colectiva en la que el Observatorio de Derecho Rural de la Universidad de Salamanca pone de relieve una vez más su compromiso con la cuestión rural.
