The dynamical analysis and microcontroller implementation of Josephson junction (JJ) oscillator with quadratic damping and topological nontrivial barrier (JJOQDTNB) is investigated in this paper. JJOQDTNB is described by nonlinear resistive capacitive inductive shunted JJ (NRCLSJJ) with 4π-periodic superconducting current. Two steady-states are obtained from the rate equations describing JJOQDTNB. According to the Routh-Hurwitz criteria, one steady-state is stable and the other steady-state is unstable. JJOQDTNB exhibits periodic oscillations, period doubling route to chaotic oscillations and coexistence between limit cycle and chaotic oscillations. The numerical simulations and microcontroller implementation results of JJOQDTNB show a good qualitative agreement.

Bananas are the most consumed fruit worldwide, especially in West Africa. However, banana plantations are often infected by the ascomycete fungus Mycosphaerella fijiensis M., the agent of black sigatoka disease (BSD), also called black leaf streak, which can lead to yield losses exceeding 50%. This fungal disease is widely reported in banana plantations in Burkina Faso, causing significant reductions in fruit yield and quality. This study aims to improve banana productivity in Burkina Faso through integrated and sustainable management. The experiment was conducted using a factorial block design with two factors: the first factor involved treatment products (Copper Hydroxide, Mancozeb, Ocimum gratissimum, and Lippia multiflora), and the second factor involved application doses at three levels, including an untreated control. The experimental material consisted of vivo-plants of the Grande Naine banana variety and the BH isolate of M. fijiensis. The in vivo results showed that all plants exhibited a 100% incidence. In preventive treatment, the disease index increased from 29.16 % to 97.22 % in the control, while Ocimum gratissimum (15.27 % to 22.22 %) and Mancozeb (15.27 % to 20.83 %) significantly limited its progression, compared to Lippia multiflora (18.05 % to 54.16 %) and copper hydroxide (16.66 % to 62.33 %). In curative treatment, the control increased from 29.16 to 97.22, O. gratissimum from 12.5 % to 19.33 %, and Mancozeb from 16.66 % to 30.55 %, while L. multiflora (18.05 % to 66.66 %) and copper hydroxide (18.05 % to 70.66 %) were less effective. The AUDPC confirms the high effectiveness of O. gratissimum and Mancozeb, suggesting their use alone or in combination as part of an integrated black sigatoka disease management strategy.

Background: Adolescence is a period marked by heightened emotional sensitivity and impulsivity. With social media becoming central to teenagers’ lives, Fear of Missing Out (FoMO) has emerged as a common emotional experience that may influence decision-making and behavior. This study explored the relationship between FoMO and impulsivity among adolescents. Methods: A total of 305 teenagers aged 15–17 years in Bangalore were recruited through purposive sampling. Participants completed the FoMO Scale and the UPPS-P Impulsive Behavior Scale. Data were analyzed using descriptive statistics, t-tests, ANOVA, and Pearson’s correlation to examine levels of FoMO, impulsivity, and their interrelationships. Results: Participants reported moderate levels of FoMO and moderate to high impulsivity. FoMO was positively correlated with overall impulsivity (r = 0.288, p < .05), particularly with negative urgency (r = 0.244) and lack of premeditation (r = 0.231). Gender differences were generally non-significant, although specific impulsivity traits showed variation. Conclusion: The findings suggest that adolescents’ emotional and behavioral functioning is influenced by their digital environment. Interventions promoting emotional regulation, mindful social media use, and reflective decision-making may benefit teens.

L’érosion hydrique est un phénomène naturel multidimensionnel de dégradation des sols variant dans le temps et dans l’espace mais souvent amplifiée par les actions anthropiques. L’objectif de cette étude est de modéliser le risque d’érosion hydrique dans le plateau d’Allada. La méthodologie adoptée pour la modélisation du risque d’érosion hydrique est l’intégration des équations empiriques de pertes en sol révisées (RUSLE) en combinaison avec les SIG. Le croisement de 5 facteurs déterminants tels que l’érosivité des pluies (R), l’érodibilité des sols (K), le couvert végétal (C), la topographie (LS) et les pratiques antiérosives (P) a permis d’identifier quatre (04) niveaux de sévérité de l’érosion hydrique sur le plateau d’Allada. A l’issu de cette étude, La cartographie de l’érosion du plateau d’Allada met en évidence une majorité de zones à érosion faible, tant dans l’érosion potentielle (86,95 %) que réelle (83,41 %), indiquant une relative stabilité des sols. Toutefois, les zones à érosion modérée (11,80 % dans l’érosion potentielle et 7,40 % dans l’érosion réelle) révèlent des zones sensibles qui nécessitent une vigilance particulière, souvent en raison de la pression exercée par des pratiques agricoles intensives. En revanche, les zones à érosion forte (0,97 % et 4,70 % respectivement dans l’érosion potentielle et réelle) et très forte (0,75 % et 4,48 % respectivement dans l’érosion potentielle et réelle) indiquent des secteurs à risques élevés, souvent associés à des pentes plus abruptes et à des activités humaines.

One of the most important ways to lessen the effects of the COVID-19 pandemic, which has caused an unprecedented global health crisis, is through vaccination. Despite the controversy surrounding COVID-19 vaccines, Covishield has been India's most popular vaccine. One and a half years after vaccination, this study examines the persistence of antibodies against COVID-19, particularly those produced by Covishield. 350 participants in total, equally split between the sexes, were chosen for this analysis. Serious public health consequences may result from the presence of antibodies years after vaccination. Our results demonstrate the effectiveness of vaccination, as 68% of samples had adequate antibody titers (>0.80 U/mL) against COVID-19. The concurrent emergence of neurological, respiratory, and cardiovascular adverse effects in those who mounted a sufficient antibody response was a noteworthy finding, though. On the other hand, individuals who were unable to produce adequate antibody levels frequently had a significant medical history, indicating that a serious illness could impair the immune response to vaccination. The significance of additional research into the variables influencing antibody development and vaccine effectiveness is underscored by these findings, which show the delicate relationship between vaccine efficacy and individual health status.

Background: Obesity is a rising public health concern in Malaysia, with more than half of adults now classified as overweight or obese. Beyond its physical health implications, obesity is strongly associated with weight stigma, which can negatively affect patient care and outcomes. Understanding healthcare students’ attitudes and beliefs toward obesity is critical, as these individuals represent the next generation of clinicians. Objectives: This study aimed to determine the prevalence of weight stigma among medical, nursing, and dentistry students at AIMST University, and to assess whether greater biomedical knowledge among medical students is associated with lower levels of stigma. Methods: A cross-sectional survey was conducted among 300 Year 2 and 3 students (100 each from medicine, nursing, and dentistry). Participants completed validated instruments: the Attitudes Toward Obese Persons (ATOP) scale, the Beliefs About Obese Persons (BAOP) scale, and the Norwegian Obesity Knowledge Questionnaire. Data were collected via Google Forms and analyzed descriptively using Microsoft Excel. Frequencies and percentages were calculated to identify key patterns and trends. Results: Respondents demonstrated mixed attitudes toward obesity. While nearly half (49%) agreed that obese individuals could be as happy as their non-obese counterparts, a significant proportion expressed scepticism regarding self-esteem and confidence among obese persons. More than 60% perceived that obese individuals are dissatisfied with themselves, and over 63% disagreed that obese people are as healthy as non-obese individuals. Beliefs about the causes of obesity were also divided: many participants attributed it to lifestyle and willpower, though a notable proportion acknowledged genetic and biological factors. Conclusion: Despite awareness of evidence-based approaches to obesity management, misconceptions and stigmatizing beliefs remain prevalent among healthcare students. The findings partially contradict the initial hypothesis, showing that medical, nursing, and dentistry students do exhibit weight stigma, though medical students demonstrated comparatively greater awareness of obesity’s complex aetiology. Targeted educational interventions that integrate empathy training, biological education, and inclusive communication strategies are warranted to reduce bias and prepare healthcare students to deliver equitable patient care.

Le secteur hôtelier, en quête constante d’excellence et de confort pour sa clientèle, repose sur une consommation importante de ressources naturelles. Derrière l’élégance des établissements et la satisfaction des clients se cache une réalité environnementale préoccupante. Chaque année, l’industrie hôtelière génère des tonnes de déchets plastiques, notamment à travers les bouteilles d’eau, les emballages de produits d’accueil, les accessoires jetables des chambres et l’usage de cartes magnétiques. La présente étude ayant pour thème « Importance de l’écoresponsabilité dans le secteur hôtelier de la ville de Porto-Novo » a pour objectif de contribuer à la pratique de l’écoresponsabilité dans le secteur hôtelier de la ville de Porto-Novo. L’approche méthodologique s’est appuyée sur la recherche documentaire, la collecte des données, le traitement des données et l’analyse des résultats. Les résultats issus de nos investigations révèlent que l’écoresponsabilité est perçue comme essentielle, mais que la mise en œuvre est encore partielle et inégale au sein des structures hôtelières de la ville de Porto-Novo. Comme actions écoresponsables nous pouvons avoir l’économie d’Energie, la gestion et tri des déchets, la réduction de la consommation en eau, utilisation des produits d’entretien écologiques, l’approvisionnement local et bio pour la restauration, la sensibilisation aux gestes écocitoyens, le recyclage des déchets. Toutefois, l'état des lieux aux niveau des hôtels montrent l’utilisation de matière première locale, l’installation de panneaux solaires ou autres énergies renouvelables à hauteur de 100% ensuite la réduction de la consommation en eau et le moins apprécié est l’inexistence de bacs de recyclage, formation au personnel et les produits d’entretien écologiques. Au regard de tout ce qui précède, des actions d’information et de sensibilisation sont à mener pour une hôtellerie durable et respectueuse de l’environnement.

Notre étude part d’une observation : la manière dont les internautes s’arrogent le droit d’annoncer le décès de quelqu’un. Nous constatons en effet, qu’à l’ère des réseaux sociaux, l’annonce de la mort qui, autrefois était réservée à la famille, devient un acte ordinaire, effectué par n’importe quelle personne disposant d’un smartphone et d’une connexion internet. Ce phénomène de plus en plus visible, nous a amené à nous interroger sur nos pratiques discursives. L’analyse du discours, cadre théorique de cette étude, nous a permis d’aborder ce phénomène comme un acte de langage socialement situé, car annoncer la mort, c’est aussi produire une certaine réalité, un effet social et symbolique. L’annonce du décès sur les Réseaux Sociaux ne se contente donc pas d’informer ; elle performativise la mort, la rend visible et partageable L’étude a ainsi mis en lumière une transformation profonde de la manière dont la mort est énoncée, vécue et partagée dans la société contemporaine.

Production of Nile tilapia (Oreochromis niloticus) is constrained by early and uncontrolled reproduction in culture, leading to overpopulation and reduced growth performance. Although sex reversal using 17-α-methyltestosterone effectively produces male monosex populations, its use raises health, environmental, and regulatory concerns. In this context, Carica papaya emerges as a promising natural alternative. This study evaluated the efficacy of Carica papaya seed powders as a substitute for 17-α-methyltestosterone in sex reversal of Nile tilapia, as well as their effects on growth, survival, and water physico-chemical quality in two strains (“Bouaké” and “Brazil”). Sexually undifferentiated larvae were exposed for 28 days to five treatments: a negative control, a positive control (70 mg/kg of 17-α-methyltestosterone), and three diets containing Carica papaya (10, 30, and 50 g/kg), in triplicate. Data were analyzed using two-way ANOVA followed by Tukey’s HSD test (p < 0.05). Water physico-chemical parameters remained stable across treatments (p > 0.05), indicating no confounding environmental effects. Carica papaya powders induced significant masculinization, reaching 85-90 % males in the “Bouaké” strain and 78-82 % in the “Brazil” strain, compared with ≥ 96 % in the 17-α-methyltestosterone treatment. The 10 g/kg dose produced the best growth performance, comparable to the hormonal treatment, while higher doses significantly reduced growth. No significant adverse effects on survival or condition factor were observed. In conclusion, Carica papaya seeds constitute a credible natural alternative to 17-α-methyltestosterone for producing male monosex populations of Oreochromis niloticus, offering a relevant compromise between biological efficacy, environmental safety, and sustainability in semi-intensive aquaculture systems.
