Published: February 2025

Economic growth experienced in Nigeria over the past decade has been primarily impacted by dwindling foreign exchange earnings. These earnings are dictated by an increasingly monolithic economy with an almost singular dependence on crude export proceeds. While various options for diversifying the economy, enhancing productivity as well as creating multiple sub-national and national income streams, abound, not much has been done towards harnessing and optimising these alternative options, hence a national Gross Domestic Product (GDP) that is impeded by regular fluctuations that have come to define the global oil market. Blue Economy (BE) as defined by the World Bank underscores, ‘the sustainable use of ocean resources for economic growth, improved livelihoods, and jobs while preserving the health of the ocean ecosystem’. In its hypothesis, this paper posits that BE presents a viable and alternative path to Nigeria’s economic diversification and growth in a manner that is not damaging to the environment and ecosystem, but boosts empowerment, job and wealth creation as key indices of sustainable development and economic growthIn its literature review, the paper connects and underlines typical literature backed cases of BE facilitating sustainable development and economic growth. Its analysis derived from global perspectives, insights and experiences, seeks to situate and apply BE prospects within the Nigerian context. These feeds the eventual proffered recommendations. In its recommendations, the paper puts forward steps that underscore a path to harnessing the Nigeria’s BE in such a way as to ensure sustainable development, and that seeks to satisfy current socio-economic diversification and growth needs, boosting wealth creation and empowerment while ensuring safe climate and environmentally friendly practices.

Published: February 2025

Tetanus toxoid vaccine prevents tetanus infection and help to boost the immune response to other vaccines. An adequately immunized woman against tetanus is able to transfer antibodies to her unborn baby which ultimately prevents the disease from occurring in her child during the early infancy period. This study aimed at assessing knowledge and perception of tetanus toxoid vaccination among female undergraduate students in Lagos State University, Ojo. A Descriptive-Cross sectional design was adopted in this study as self-structured questionnaire was used in collecting data from 233 respondents. Data was analyzed using Statistical Package for Social Science (SPSS) software version 26. Frequency tables and percentages was used for the descriptive analysis of the study while Chi-Square was used to test for significant relationship between variables at 0.05 level of significance. The study found that participants had poor knowledge about tetanus toxoid vaccination, with misconceptions about its administration and timing, but held a generally satisfactory perception of the vaccine, rejecting myths about its cost and effects. Less than half had received the vaccine, and many had not completed the full schedule, while a significant relationship was observed between their level of knowledge and perception of the vaccine. The study concludes that while participants have a satisfactory perception of tetanus toxoid vaccination, their knowledge is poor, with less than half having received the vaccine, and there is a significant relationship between knowledge and perception. It was therefore recommended among others that there should be development and implementation of educational campaigns aimed at female undergraduate students to enhance their knowledge, perception and utilization of tetanus toxoid vaccination.

No campo das cirurgias invasivas, especialmente na articulação temporomandibular (ATM), a busca por técnicas menos invasivas ou seu aprimoramento tem se intensificado, resultando em procedimentos mais seguros e menos traumáticos. Os cirurgiões bucomaxilofaciais utilizam tecnologias que tornam as cirurgias mais precisas, com menores impactos estéticos e psicológicos. Um exemplo é uma paciente de 32 anos com estalidos e crepitações na ATM, dores articulares e fadiga muscular. Após anos de fisioterapia com melhora parcial, optou-se pela artroscopia, que resultou na eliminação da dor e no retorno às atividades diárias. Procedimentos como artroscopia, artrocentese e artrotomia trazem vantagens como menor tempo de recuperação, redução de cicatrizes e menor risco de complicações. Embora a artroscopia seja a principal escolha, a artrotomia ainda é necessária em casos específicos, enquanto a artrocentese é uma opção acessível e menos invasiva, mas limitada em casos complexos. O pós-operatório tem mostrado impacto positivo, com menos dor e retorno rápido às atividades. A inteligência artificial promete avanços ainda maiores, com diagnósticos mais rápidos e procedimentos mais precisos. Em suma, os avanços tecnológicos nas cirurgias da ATM melhoram resultados, recuperações e qualidade de vida.

The Fallibility of Equipartition Magnetic Field Strengths from Synchrotron Emission Using Synthetically Observed Galaxies
Authors: Dacunha Tara , Martin-Alvarez Sergio , Clark Susan E. , Lopez-Rodriguez Enrique
Published: February 2025

Understanding the role that magnetic fields play on the stage of galaxy formation requires accurate methods for inferring the properties of extragalactic magnetic fields. Radio synchrotron emission has been the most promising avenue to infer magnetic field strengths across galaxies, with the application of a central assumption: that galactic cosmic rays are in energy equipartition with the magnetic field. In this work, we leverage flexible synthetic observations of a high-resolution magnetohydrodynamic simulation of a Milky Way–like galaxy to review whether true equipartition is capable of reproducing radio observations of galaxies, and investigate its impact on the inference of magnetic field strengths when varying the properties and density distribution of the cosmic rays. We find that imposing equipartition (regardless of scale length) results in cosmic ray electron densities that are unable to generate either the amplitude or the shape of the radio intensity profiles typically observed in spiral galaxies. Instead, observationally motivated smooth distributions of cosmic ray electrons across the galaxy provide a remarkable match to observations. We further demonstrate that assuming equipartition with those mock observations can lead to significant overestimation of the magnetic field strength. This misestimation varies with cosmic ray electron densities, cosmic ray spectrum power-law index, and galactic environment, aggravated in inter-arm regions and attenuated in star-forming regions. Our results promote caution when assuming equipartition in observations, and suggest that additional theoretical and numerical work is required to leverage the upcoming generation of radio observations poised to revolutionize our understanding of astrophysical magnetic fields.
Adiabatic Index in Fluid Models of Collisionless Black Hole Accretion
Authors: Gammie Charles F.
Published: February 2025

Models of highly sub-Eddington accretion onto black holes commonly use a single-fluid model for the collisionless, near-horizon plasma. These models must specify an equation of state. It is common to use an ideal gas with p = (γ − 1)u and γ = 4/3, 13/9, or 5/3, but these produce significantly different outcomes. We discuss the origins of this discrepancy and the assumptions underlying the single-fluid model. The main result of this investigation is that under conditions relevant to low-luminosity black hole accretion the best choice of single-fluid adiabatic index is close to but slightly less than 5/3. Along the way we provide a simple equilibrium model for the relation between the ion-to-electron dissipation ratio and the ion-to-electron temperature ratio, and explore the implications for electron temperature fluctuations in Event Horizon Telescope sources.
Signatures of Rapidly Rotating Stars with Chemically Homogeneous Evolution in the First Galaxies

Published: February 2025

The James Webb Space Telescope (JWST) has revealed an unexpectedly high abundance of UV luminous galaxies at redshifts z ≳ 10, challenging “standard” galaxy formation models. This study investigates the role of rapidly rotating (massive) stars undergoing chemically homogeneous evolution (CHE) in reconciling this potential tension. These stars are more compact, hotter, and exhibit enhanced UV emission. We find that the rest-frame UV luminosity of star-forming galaxies can be significantly enhanced by a factor of  ∼3−6 when CHE stars above a minimum initial mass of

account for more than half of the total stellar mass following a Salpeter initial mass function. As a result, the UV luminosity functions observed at z ∼ 12−16 can be reproduced with less extreme values of star formation efficiency and UV luminosity stochastic variability. Our results highlight the potential of CHE in explaining the UV-bright galaxy populations detected by JWST and call for future work to explore the broader astrophysical implications of CHE and its associated phenomena in the early universe, such as gamma-ray bursts, compact object binaries, and metal enrichment.

Published: February 2025

This study examines the bending dynamics of cantilevered single-crystalline bimorphs made from bidomain LiNbO3 (BLN), emphasizing the interaction between bending resonances, antiresonances, and torsional vibrations. Combining theoretical modeling and experimental validation, we demonstrate that a 1D analytical model, based on classical beam theory, surpasses FEM modeling in predicting bending resonances, particularly in the low-frequency range. The analytical model provides precise positioning of resonant frequencies, enabling the strategic alignment of torsional resonances with bending antiresonances, as confirmed experimentally. Our findings underscore the high predictability of BLN-based bimorphs, allowing accurate descriptions of their behavior at bending resonances, antiresonances, and piezoelectrically passive torsional resonances. Unlike glued actuators made of lead-based ceramics, BLN bimorphs offer superior thermal stability, long-term reliability, and predictable performance. These properties, combined with the availability of commercially produced LN crystals, position BLN-based bimorphs as ideal candidates for MEMS applications, enabling advanced sensing and actuation solutions with reduced reliance on complex feedback loops.

Using in situ reflection electron microscopy we have presented latest studies of Si(111) and Bi2Se3(0001) surface processes during sublimation, homo- and heteroepitaxial growth of layered metal chalcogenides. A structural kinetic diagram of interaction between a selenium molecular beam and Si(111) surface has been demonstrated. We have shown congruent sublimation caused by annealing of Bi2Se3(0001) substrates in a selenium flux, visualized and described layer by layer homoepitaxial Bi2Se3 growth. We have presented techniques of layered SnSe2 and In2Se3 growth on Si(111) and Bi2Se3(0001) surfaces and shown that heteroepitaxial growth starts with the 2D islands formation. The nucleation and growth of an impurity-induced phase in the form of 0.4 nm high 2D islands during high-temperature submonolayer indium deposition on Bi2Se3(0001) under exposure to Se molecular beam has been demonstrated.

Deep-sea corals are critical to global exploration of deep-sea biodiversity, but research on them in the Indian Ocean is very limited. In this study, we report the first discovery of two new species of red corals at a depth of 1697 m in the western Indian Ocean. The species were identified through detailed morphological analysis, including microscopic examination of colony structure, branches and autozooids (assessing size, abundance and spacing), as well as scanning electron microscopy (SEM) of sclerite morphology and quantity. Two species for the genus Hemicorallium Gray, 1867 were found as new species, designated Hemicorallium indicodensumsp. nov. and Hemicorallium jiaolongensissp. nov.H. indicodensumsp. nov. is characterised by densely branched structures and numerous globular double-club sclerites, distinguishing it from other species. Meanwhile, H. jiaolongensissp. nov. features yellowish-white colonies with short rods with sharp, large radial projections in the tentacles. Four mitochondrial regions were used to reveal the phylogenetic relationship in Coralliidae, supporting the taxonomic placement of these two new species. This study provides significant new insights into the biodiversity of deep-sea corals in the Indian Ocean, enriching the known species pool. Additionally, a more comprehensive key to the genus Hemicorallium is provided, further enhancing our understanding of the group’s taxonomy.
Conduite à tenir lors d’une thrombocytose

Published: February 2025

Définie par un taux de plaquettes dans le sang > 400 G/L, la thrombocytose n’est explorée, en pratique, que quand elle est > 450 G/L. Les interférences analytiques pouvant faussement élever le nombre de plaquettes doivent être bien connues du biologiste afin d’éviter des investigations inutiles. Très souvent d’origine réactionnelle, la thrombocytose peut également être primitive dans le cadre d’une hémopathie maligne ou plus rarement d’une pathologie héréditaire. Les complications thrombotiques ou hémorragiques associées à la thrombocytose ne sont pas directement corrélées au taux sanguin de plaquettes mais au contexte médical sous-jacent qui doit être exploré. Les néoplasies myéloprolifératives, dont la thrombocytémie essentielle, exposent à un risque thrombotique et hémorragique qui impacte le pronostic de cette hémopathie.

Published: February 2025

Contexte – En France, les informations recueillies lors des consultations post-don montrent qu’une majorité de donneurs de sang infectés par le VIH auraient dû être ajournés, car ne répondant pas aux critères de sélection. Afin de maintenir un niveau de sécurité transfusionnelle optimal, il était important de mieux comprendre les raisons pour lesquelles l’étape de sélection n’avait pas permis d’écarter ces donneurs, notamment les hommes ayant des rapports sexuels avec des hommes (HSH). Matériel et méthodes – Des entretiens individuels semi-directifs ont été réalisés avec 32 donneurs de sang trouvés VIH positifs entre mi-2011 et 2014, dans l’objectifde recueillir des informations sur leur expérience et leurs motivations pour le don du sang, leur compréhension des critères de sélection, leur gestion du risque sexuel et leur opinion sur le processus de sélection des donneurs. Les entretiens ont été analysés dans une logique inductive. Résultats – Plus de 50 % (17/32) des participants à l’étude n’étaient pas compliants aux critères de sélection des donneurs de sang. Parmi les principales raisons de non-déclaration des facteurs de risque dans le questionnaire ou lors de l’entretien pré-don figuraient la crainte de la stigmatisation, la surveillance du statut VIH, l’attachement symbolique au don de sang et le contexte du don (confidentialité, type de collecte…). Par ailleurs, l’évaluation des comportements sexuels à risque n’était pas toujours bien appréhendée par les donneurs eux-mêmes. Enfin, la notion de « fenêtre silencieuse » et les arguments épidémiologiques sur lesquels se basent les critères de sélection des donneurs étaient mal compris. La majorité des participants à l’étude étaient opposés à l’ajournement permanent des HSH. Conclusion – Cette étude a montré la nécessité d’une meilleure communication sur la fenêtre silencieuse et sur les fondements épidémiologiques sur lesquels reposent les critères de sélection des donneurs de sang pour améliorer leur compliance. Ces résultats ont déjà permis l’amélioration du questionnaire pré-don, dans le contexte de la révision des critères de sélection des donneurs intervenue en 2016.

Les patients atteints de cancer présentent un état d’hypercoagulabilité sanguine d’origine acquise. Ainsi, la maladie thromboembolique veineuse (MTEV) est la seconde cause de décès chez ces malades et constitue un enjeu majeur de santé publique. Les héparines de bas poids moléculaire (HBPM) sont actuellement les médicaments de référence dans la MTEV survenant chez des cancéreux. Les anticoagulants oraux directs (AOD) se présentent néanmoins comme une alternative thérapeutique chez certains patients après évaluation des interactions médicamenteuses, en l’absence de risque hémorragique majeur.
Actualisation des connaissances sur les virus herpes simplex
Authors: Boutolleau David , Burrel Sonia
Published: February 2025

Les virus herpes simplex 1 et 2 (HSV-1 et HSV-2) sont de grands virus enveloppés dont le génome est constitué d’ADN. Au-delà de l’infection initiale, ces virus strictement humains établissent à vie, dans l’organisme de l’hôte, une infection latente dans les ganglions nerveux sensitifs, ponctuée de phases de réactivations virales. Bien adaptés à leur hôte, ils sont responsables le plus souvent d’infections limitées et majoritairement asymptomatiques. À côté des manifestations classiques de l’herpès oral (dû au HSV-1) et de l’herpès génital (dû au HSV-1 ou au HSV-2), il existe des infections graves dues à des atteintes oculaires, à l’immaturité du système immunitaire du nouveau-né, à l’immunodépression et à des atteintes du système nerveux central. Le diagnostic des infections aiguës est établi par la détection du génome viral dans les échantillons biologiques par amplification génique ( polymerase chain reaction [PCR]), la sérologie ayant essentiellement un intérêt épidémiologique. Les HSV sont sensibles à un antiviral efficace et très bien toléré : l’aciclovir, administré par voie intraveineuse, ou sa prodrogue, le valaciclovir, administré par voie orale. La prévention des infections repose principalement sur de simples règles d’hygiène, l’utilisation de préservatifs lors des rapports sexuels, la désinfection des voies génitales maternelles avant l’accouchement et la réalisation d’un accouchement par césarienne. Actuellement, il n’existe pas de vaccin anti-HSV.

Phishing Attack Response and Risk Mitigation Using Deep Learning and Machine Learning
Authors: Bhimavarapu Usharani
Published: February 2025

Phishing attacks have emerged as one of the most prevalent and damaging forms of cyber threats, posing significant risks to the security and privacy of users on the internet. These attacks typically involve fraudulent websites designed to deceive users into disclosing sensitive information, such as passwords, credit card details, and personal data. Detecting phishing websites has become a critical task in cybersecurity, as traditional methods often fail to effectively identify new and sophisticated phishing tactics. This study addresses this challenge by leveraging a carefully curated dataset containing 10,000 instances of URLs and web page features, specifically designed for phishing detection. A combination of advanced machine learning techniques, including feature extraction using ResNet50 and classification with Support Vector Machine (SVM), is employed to accurately distinguish between legitimate and phishing websites. SMOTE is used for data balancing to mitigate class imbalance, ensuring that both classes are adequately represented during training. The proposed approach demonstrates a significant improvement in detecting phishing websites by effectively capturing complex patterns and characteristics indicative of phishing activity. The results underscore the potential of deep learning and machine learning methods in enhancing the accuracy and reliability of phishing detection systems.

Parkinson’s disease (PD) is a progressive neurodegenerative disease that primarily manifests as a movement disorder. It significantly affects the quality of life of individuals, who often experience stigma, disability, and social isolation. These outcomes are largely attributed to the widespread myths and misconceptions surrounding the disease, leading to negative consequences in workplaces, public interactions, and mental health. Therefore, it is crucial to raise awareness about PD, strengthen peer networks, foster supportive community environments, and ensure that healthcare professionals are trained to provide empathetic, patient-centered care. In conclusion, this study underscores the indispensable need for a comprehensive, multi-faceted approach to address the challenges faced by individuals with PD.

Published: February 2025

Voriconazole (VOR) is a triazole antifungal agent; it blocks the synthesis of ergosterol, available in the market orally and intravenously, but, not without various side effects. The aim of this study is development and characterization of VOR oleogel for the topical treatment of skin fungal infection to avoid the drug’s systemic side effects that are associated with oral and IV routes. The gelator Span 60 (S) was added at different concentrations to different oils (oleic OO, grapeseed GO, and sesame oil SO) to obtain the minimum gelation concentration, the prepared formulas were subjected to various evaluation tests, and the optimum formula was checked for antifungal effect, and subjected to viscosity, and texture analysis. The optimized formula, Span60 with SO 14SSO, showed 100% drug release, good antifungal activity, and acceptable transition temperature. The study of viscosity demonstrated the pseudo-plastic shear thinning behavior. A Fourier-transform infrared study showed that the drug and excipients did not significantly interact. 14SSO might be a promising topical treatment option for skin fungal infections.

Published: February 2025

This Oberwolfach workshop was dedicated to continuing the sequence on “Atmosphere-Ocean Science” from (2002, 2006, 2010). The spirit of these events is that of an open invitation to engage in an eye-level exchange on recent developments and pressing challenges in each of the participating disciplines, and to explore possible new routes of interdisciplinary cooperation. This workshop emphasized “model hierarchies” and their importance for the systematic development of both theoretical understanding and methods of scientific investigation. To limit its scope, the workshop focused on (i) scale interactions in the atmosphere and oceans, (ii) thermodynamics and multiphase processes, and (iii) tropical-extratropical interactions from the applied perspective. From a mathematics perspective, challenging aspects of the derivation, justification, and numerical integration of hierarchical reduced models were addressed. Moreover, the workshop explored the potential applicability in atmosphere-ocean science of exciting recent results of mathematical fluid dynamics on “rough path” stochastic modelling and “wild” weak solutions of the Euler and Navier-Stokes equations.

Recent results on moduli spaces of various types (of sheaves, complexes, varieties) played a prominent role in many of the talks, as well as derived categories of coherent sheaves. A number of talks were devoted to the geometry of special varieties (Calabi–Yau, hyperkähler) and to the geometry of the Hitchin system.
Diesel Engine Performance and Combustion Imaging Analysis of
Gas-to-Liquid and Polyoxymethylene Dimethyl Ether Blended Fuels

To reduce carbon dioxide emissions from automobiles, the introduction of electric
vehicles to the market is important; however, it is challenging to replace all
existing IC engine vehicles with electric ones. Consequently, there is
increasing anticipation for the use of carbon-neutral fuels, such as
e-fuels.

This study investigates the effects of GTL (gas-to-liquid), as a substitute for
e-fuel, produced from natural gas via the Fischer–Tropsch synthesis method and
polyoxymethylene dimethyl ether (OMEmix) produced from methanol, on
engine performance. Additionally, combustion image analysis was conducted using
a rapid compression and expansion machine (RCEM).

GTL fuel combusts similarly to conventional diesel fuel but has slightly lower
smoke emissions because it does not contain aromatic hydrocarbons. Further, its
high cetane number results in better ignition properties. During the combustion,
unburnt hydrocarbons and smoke are generated in the spray flame interference
region near the cylinder wall due to insufficient oxygen, and as it moves from
the cylinder wall toward the center of the cylinder, the re-oxidation is
observed, which is reflected in the heat release rate as the after-burning
duration.

When the OMEmix is mixed with hydrocarbon fuels such as GTL,
combustion continues even in the spray flame interference region, leading to a
reduction in the after-burning duration and significantly lower smoke
emissions.

Further, the GTL was divided into four distillation regions, that are GTL Light,
GTL Light Middle, GTL Middle Heavy, and GTL Heavy, and the effects of low and
high-boiling fractions in GTL on diesel combustion were investigated. Heavy
fractions have excellent ignition properties, resulting in shorter lift-off
(set-off) length during combustion. However, due to the poor evaporation
characteristics, they have longer high-temperature residence time, leading to
greater cooling losses and reduced thermal efficiency. On the other hand, light
fractions have longer lift-off lengths, mix well with air before combustion, and
have shorter combustion durations compared to heavy fractions. Finally, an
engine performance was evaluated using a fuel mixture of the fuel with the heavy
fractions removed from GTL (heavy-cut GTL) and OMEmix in a 1:1
ratio.

C. vulgaris is photoautotrophic, which refers to microalgae that require light as an energy source. One of the light sources used to affect pigments in microalgae is UV light. The advantage of UV light is that it can change gene composition, which results in mutant genes in biopigment mutations and causes a higher number of activities compared to the natural ones, thereby increasing the growth, carotenoids, and chlorophyll-a of microalgae. The aim of this research is to determine the effect of oxidation stress of UV light on growth, carotenoids and chlorophyll-a content of Chlorella vulgaris. The treatments were given based on differences in the power of the UV-C light from, 8W, 15W and 30W. This study used the UV-Vis Spectrophotometer method was used to calculate growth, carotenoids and chlorophyll-a. Data were analysed using ANOVA test, Duncan's Multiple Range Test, and Principal Component Analysis (PCA). The results showed a significant effect of UV-C light. The best treatment was found in the administration of 30 W UV light, with the results of growth was 4.7746 × 106 cells/ml, content of carotenoids was 1.75 mg/ml and chlorophyll-a was 4.67 mg/ml of C. vulgaris. Biopigment can absorb radiation from UV-C light, which causes these microalgae to survive in environmental stress conditions. Absorbed light can affect the spectrum of pigments, thereby increasing growth, carotenoids, and chlorophyll-a.

In today’s dynamic business landscape, Small and Medium-sized Enterprises (SMEs) encounter growing challenges in achieving sustainability. Logistics capabilities and supply chain performance play a crucial role in the strategic operations of SMEs, making the adoption of digital technology increasingly vital. However, despite its acknowledged importance in logistics and supply chain management, there is a lack of detailed understanding regarding how digital technology specifically impacts the sustainability of SMEs. This gap highlights the need for focused research into its influence on logistics capabilities, supply chain performance, and overall sustainability. To address this, the study utilized an explanatory single cross-sectional survey method for data collection, employing a stratified sampling technique to draw a sample of 230 participants. The findings revealed that logistics capabilities positively and significantly influence supply chain performance and the sustainability of SMEs. Moreover, digital technology was found to positively moderate the relationship between logistics capabilities and supply chain performance, as well as the relationship between logistics capabilities and sustainability. Based on these findings, the study recommended that organizations adopt advanced data analytics tools to maximize the potential of supply chain data, implement Internet of Things (IoT) technologies for real-time monitoring and enhanced visibility, and utilize cloud-based collaboration platforms to ensure seamless communication and information sharing among supply chain partners.
