A busca por fontes energéticas mais limpas, visando a substituição dos combustíveis fósseis, faz da biomassa uma alternativa bastante promissora. Diante disso, o estudo térmico e cinético de uma determinada matéria-prima é um processo bastante importante para a visualização de sua viabilidade na geração de biocombustíveis, pois fornece informações, como temperaturas de perdas mássicas e energias necessárias para a reação de sua degradação. Em vista disso, o presente trabalho estudou o comportamento da degradação térmica do óleo de mamona, suportado em Al-MCM-41 e MoNi-Al-MCM-41, além de realizar um estudo cinético com as informações obtidas. As melhores energias de ativação foram para a amostra de óleo com o Al-MCM-41, onde acredita-se que a presença dos metais molibdênio e níquel no MoNi/Al-MCM-41 diminuiu a acidez do material, ocasionando um aumento na energia de ativação quando comparada a reação com o Al-MCM-41.

O crescimento da utilização do biogás como um ativo energético, neutro em carbono, impulsionou o desenvolvimento de pesquisas de novas rotas para o seu aproveitamento. Em meio a este cenário, as reformas catalíticas passaram ser uma opção extremamente interessante, tento em vista que possibilitam a conversão do biogás em gás de síntese (H2+CO), insumo necessário para a produção de combustíveis avançados sustentáveis e de alto valor agregado, por meio de processos conhecidos como “Power to X”. À vista disso, este trabalho se propõe a realizar uma revisão bibliográfica dos processos de reforma a seco, bi- reforma e tri-reforma, de modo a analisar suas principais características e identificar as particularidades de cada tecnologia para a sua aplicação na cadeia do biogás. Como parâmetros de comparação, foram selecionados 7 critérios, sendo eles: literatura disponível, gasto energético, conversão de CO2, Razão de Biogás (CH4/CO2), nível de complexidade da planta, formação de coque e a razão H2/CO de gás de síntese.

A cinética da reação de decomposição térmica e termocatalítica do óleo de girassol foi avaliada com a utilização de métodos isoconversionais, i.e., FWO (Ozawa-Flynn-Wall) e KAS (Kissinger-Akahira-Sunose), em três taxas de aquecimento (5, 10 e 20 ºC min-1), na faixa de conversão entre 20% e 80%. Os métodos apresentam um nível de confiança, ao apresentarem numericamente valores de Ea, i.e., energia de ativação aparente, relativamente próximos. A decomposição térmica da oleaginosa ajudará a entender, nos limites estudados, os possíveis produtos para produção de combustível verde. No processo catalítico, os catalisadores microporoso H-ZSM-5 e mesoporoso Al-MCM-41 foram utilizados por apresentarem acidez elevada, o que ajudará na produção de um biocombustível com baixos teores de oxigenados. As energias de ativação aparente para 50% de conversão do óleo de girassol na ausência de catalisadores utilizando os métodos FWO e KAS foram 262,56 e 255,35 kJ mol-1, respectivamente; já, a mistura OGMH1 (na presença de material catalítico), apresentou para os mesmos 50% de conversão valores de Ea correspondentes a 152,23 e 143,18 kJ mol-1, respectivamente.

O crescimento do consumo de Sustainable Aviation Fuels (SAF) ao redor do planeta cria a demanda por laboratórios acreditados que certifiquem a qualidade dos combustíveis produzidos através das rotas homologados pela ASTM, visando garantir um padrão internacional de qualidade e segurança para o transporte aéreo. Nesse cenário, surgiu a proposta de criação do Primeiro Laboratório de Certificação de SAF do Brasil. Com o aporte de recursos de diversos parceiros, o Laboratório de Ensaios de Combustíveis (LEC) da UFMG tem o objetivo de implementar e acreditar 100% dos testes previstos na legislação. Para isso, foi realizado um levantamento dos ensaios, equipamentos e seguiu-se uma série de etapas para a acreditação dos mesmos junto ao Inmetro. Até o momento, o LEC acreditou 44% dos testes e planeja finalizar o processo em 2024. Alguns desafios foram encontrados durante o percurso, como o atraso das obras de readequação do layout do laboratório devido à pandemia do Coronavírus. O laboratório vem participando do programa interlaboratorial da ASTM (EUA) e tem realizado análises de querosene fóssil para empresas aéreas, distribuidoras, aeroportos e pesquisadores do Brasil.

As problemáticas ambientais causadas pelo uso de combustíveis fósseis somado ao esgotamento das reservas petrolíferas têm ampliado o interesse pelo uso dos biocombustíveis devido seu caráter renovável e biodegradável. Entretanto, a sua implementação na matriz energética aumentou a probabilidade de contaminação e derramamentos por biocombustíveis. Nesse caso é necessário a aplicação de tecnologias eficientes para a eliminação e recuperação do conteúdo oleoso no solo ou água. O presente trabalho visa avaliar e comparar a capacidade de remoção do biodiesel (B100) pelas fibras da Calotropis procera (CP), Ceiba speciosa (CS) e Gossypium arboreum (GA) em cenários de derramamento. A fibra de CP apresentou maior hidrofobicidade. As três fibras apresentaram bons resultados na absorção do B100, com a capacidade de sorção quantificada superior a 60 g/g. Entretanto, a fibra de CS destaca-se na remoção do óleo no cenário de derramento em água, no qual absorve cerca de 1,6 e 1,9 vezes a mais do que CP e GA, respectivamente.

Neste estudo é proposta e aplicada uma metodologia para identificação de possíveis oportunidades de produção de bio-querosene no país para atender demandas em aeroportos que estejam distantes de refinarias produtoras do combustível ou portos de importação, chamadas de hotspots. Com base em dados disponíveis na Agência Nacional da Aviação Civil (ANAC), elaborou-se um ranking de principais aeroportos do Brasil, adotando o ano base de 2018, sob a ótica da demanda de serviço de passageiro-quilômetros pagos (RPK), e aproximam-se esses valores para consumo de querosene de aviação. Para produção da bio-querosene, são avaliadas duas rotas – Alcohol to Jet (ATJ), processando cana de açúcar, milho ou trigo, e Hydroprocessed Esters and Fatty Acids (HEFA), processando óleo de soja. Identificam-se dois principais hotspots, hipotéticas biorefinarias próximas aos aeroportos internacionais de Brasília e Fortaleza, que utilizariam baixos percentuais do potencial energético do estado para o cultivo de milho, menores que 1%, para produzir bio-QAV de forma a compor, junto com a querosene fóssil, em proporção certificada de 50%, um combustível condizente com ambições para mitigação climática no setor.

A Atuação internacional de cidades pequenas : um diagnóstico do potencial internacional da cidade de Marau, no Rio Grande do Sul
Authors: Macedo Gabriel Vieira de , Gomes Joséli Fiorin
Published: September 2024

A paradiplomacia se caracteriza pela atuação internacional de entes subnacionais, como cidades e estados. A atuação internacional municipal, apesar de oferecer grandes meios de fortalecer as políticas públicas, se concentra ainda nos grandes centros, onde a atividade internacional e a capacidade técnica se mostram mais presentes. O Brasil é um país de cidades pequenas: dos 5.568 municípios brasileiros, pouco mais de seiscentos passam dos 50 mil habitantes. Se os efeitos das relações internacionais estão cada vez mais presentes no dia a dia do cidadão, por que a ação internacional se desenvolve mais apenas nos grandes centros? Diante disso, esta pesquisa busca analisar a possibilidade de uma inserção internacional por parte de um município de pequeno porte, a partir do estudo de caso da cidade de Marau, no noroeste do Rio Grande do Sul. Para isso, buscou-se analisar os elementos funcionais e estruturais do município, aos moldes de Daniel Villarruel, para, assim, encontrar o chamado Interesse Local Internacional (ILI), ou seja, o potencial internacional local, diante das oportunidades observadas e das limitações geográficas, legais e políticas tidas.

Georgia's rich biodiversity, as a key part of the Caucasus hotspot, makes it an ideal destination for scientific research. Nevertheless, knowledge about the species diversity of different animal groups in this area remains limited. In this article we provide information on the nine centipede species (Henia brevis (Silvestri, 1896), H. hirsuta Verhoeff, 1928, H. taurica (Sseliwanoff, 1884), Strigamia caucasia (Verhoeff, 1938), S. pusilla (Sseliwanoff, 1884), Harpolithobius spinipes Folkmanová, 1958, Lithobius antipai Matic, 1969, L. foviceps Muralevitch, 1926, and L. micropodus (Matic, 1980)) newly recorded in Georgia. Three of these species (H. brevis, H. hirsuta, and L. micropodus) are also new records for the Caucasus region. Data on their distribution, maps of the localities, and photos of the specimens studied are also given.
Histoire(s) de la diplomatie culturelle française
Authors: Monier Anne
Published: September 2024

Si la diplomatie a toujours été conçue comme une fonction proprement étatique, les débats récents posent la question de l’émergence de nouveaux acteurs – notamment privés – sur la scène diplomatique internationale et de nouvelles formes de diplomatie. Ce chapitre vise à s’inscrire dans la lignée de ces travaux qui amènent à repenser la diplomatie au-delà du secteur public, en se demandant s’il s’agit d’une nouveauté, et en montrant les traces que l’on pouvait déjà percevoir au début du xx e siècle d’une importance des acteurs privés dans la diplomatie culturelle. Notre contribution s’intéresse notamment à la diplomatie philanthropique, à travers le cas de la donation Rockefeller, mais aussi plus largement à travers des exemples plus actuels, qui s’inscrivent dans la droite ligne de cette pratique assez méconnue dans l’historiographie traditionnelle. Il permet aussi d’ouvrir une réflexion sur les archives qui peuvent être consultées pour penser la diplomatie culturelle et ses frontières – en particulier, l’usage des archives privées. Offrant un point de vue quelque peu nouveau sur la philanthropie, ce chapitre invite également à une mise en perspective plus large des acteurs de la diplomatie dans la période contemporaine, à l’heure où le rôle des acteurs privés est croissant.

Les alliances françaises (AF) au centre de cette contribution sont de véritables instruments de diffusion de la culture française au Cameroun. Elles émanent de la matérialisation des accords de coopération culturelle signés entre le Cameroun et la France en 1960 et renouvelés le 21 février 1974. Elles ont pour objectif de développer les activités culturelles locales. Elles contribuent notamment à une meilleure connaissance mutuelle entre les deux pays par un développement des échanges culturels et linguistiques ; à la promotion de la lecture (bibliothèque) ; au développement des activités culturelles (expositions, théâtre, musique, danse, cinéma, ateliers de pratique artistique et littéraire) ; à l’instauration du débat d’idées ; à l’association de davantage de jeunes Camerounais à la vie culturelle. Trente ans après leur ouverture au Cameroun, il apparaît que ces AF ont vulgarisé la culture française à travers la formation des couches sociales les plus vulnérables, le développement des activités culturelles, mais aussi le recyclage du personnel enseignant. Toutefois, de nombreuses difficultés entravent leur fonctionnement.

Histoire(s) de la diplomatie culturelle française
Authors: Houguet Adrien
Published: September 2024

Avec la chute de l’Union soviétique, de nouvelles perspectives se sont ouvertes pour l’Allemagne et la France en Europe de l’Est, notamment en matière d’action culturelle et artistique. La promesse d’une maison commune de l’Oural à l’Atlantique a aussi changé les buts et les modalités de la diplomatie culturelle dans cet espace. Plus encore que la promotion d’une meilleure connaissance mutuelle entre les peuples européens, c’est la volonté de renforcer l’idée d’Europe et ses valeurs démocratiques qui était visée par les initiatives d’échanges culturels entre les pays européens. En Russie contemporaine, l’Allemagne et la France ont poursuivi des objectifs similaires : il ne s’agissait pas seulement de promouvoir sa culture nationale, mais de créer des espaces d’échanges et de création culturels avec les partenaires russes. Aussi, les acteurs des différents États membres de l’Union européenne ont progressivement intensifié leurs échanges afin de coordonner leurs différentes activités culturelles sur le territoire russe. Le couple franco-allemand fait ici figure de pionnier dans une potentielle future diplomatie culturelle européenne. Toutefois, avec la pandémie de Covid, la montée des tensions politiques de ces dernières années et la guerre en Ukraine, nous devons nous demander si la coopération culturelle va pouvoir perdurer. Sur le moyen terme, le projet de la maison commune européenne apparaît plus que jamais comme une chimère. À défaut d’améliorer la situation politique, les liens culturels incarnent encore la forme incompressible du partenariat entre la Russie et le reste de l’Europe. Les instituts culturels français et allemands continuent donc, dans l’ombre de la médiasphère, de maintenir des relations culturelles en attendant des jours meilleurs.

Multiplicity and concentration of normalized solutions for a Kirchhoff type problem with $ L^2 $-subcritical nonlinearities
Authors: Ni Yangyu , Sun Jijiang , Chen Jianhua
Published: September 2024

In this paper, we studied the existence of multiple normalized solutions to the following Kirchhoff type equation:

   \begin{document}$ \begin{equation*} \begin{cases} -\left(a\varepsilon^2+b\varepsilon\int_{\mathbb{R}^3}|\nabla u|^2dx\right)\Delta u+V(x)u = \mu u+f(u) & {\rm{in}}\;\mathbb{R}^3, \\ \int_{\mathbb{R}^3}|u|^2dx = m\varepsilon^3 , u\in H^1(\mathbb{R}^3) , \end{cases} \end{equation*} $\end{document}

where $ a $, $ b $, $ m > 0 $, $ \varepsilon $ is a small positive parameter, $ V $ is a nonnegative continuous function, $ f $ is a continuous function with $ L^2 $-subcritical growth and $ \mu\in\mathbb{R} $ will arise as a Lagrange multiplier. Under the suitable assumptions on $ V $ and $ f $, the existence of multiple normalized solutions was obtained by using minimization techniques and the Lusternik-Schnirelmann theory. We pointed out that the number of normalized solutions was related to the topological richness of the set where the potential $ V $ attained its minimum value.

Published: September 2024

Intensity modulation/direct detection (IM/DD) remains to be the preferred optical transmission scheme for short-range applications for its simplicity of application, inexpensiveness, and small footprint. However, the impairments of low-cost device and fiber chromatic dispersion lead to the limitation of system performance when the data rate rises to 100 Gbps or higher. In this paper, we demonstrated that an equalizer using neural networks can effectively improve the transmission performance of high-speed IM/DD systems. An optimization of a long short-term memory (LSTM) structure in terms of network depth and distribution of neurons in hidden layers leads to an enhancement of the overall performance of the 50 Gbaud PAM4 communications. Furthermore, the results for a system using a LSTM-based equalizer give the better outcome than the traditional feed-forward equalizer (FFE) or artificial neural network (ANN)-based equalizer.
Special Features of Using Mathematical Modeling for the Study of Tetrahedral Elements
Authors: Pasternak Viktoriya , Ruban Artem , Pasynchuk Kyrylo , Polyanskyi Pavlo
Published: September 2024

In this scientific work, mathematical modeling of tetrahedron elements in the finite element method is presented, which includes the determination of geometric shape, shape functions, and material properties. Unknown fields such as displacement vectors, strain, and stress tensors are considered. The methodology of applying the principle of virtual work and equilibrium equations is described, allowing the derivation of a system of differential equations to describe the behavior of the tetrahedral element. Integration over the volume and consideration of boundary conditions help reduce the equations to a system of linear algebraic equations for numerical solution using the finite element method. It was found that modeling tetrahedral elements with a specific given radius (for example, R=0.3 mm) involves stages such as geometry determination, element generation, shape function formation, stiffness matrix computation, and solving a system of linear equations. The radius R of tetrahedral elements is taken into account at all stages, ensuring accuracy and reliability in tetrahedra modeling. The research also focuses on the fact that the occurrence of minor errors in iterative processes may result from several factors, including iteration step, the number of iterations, stopping criteria, linear or nonlinear material behavior, solution method selection, the presence of geometric inhomogeneities, and element size.
Justification of the Dynamics of Extra-Project Loads on Building Structures
Authors: Nalysko Mykola , Makhinko Anna , Sopilniak Artem , Cheberiachko Yurii
Published: September 2024

The paper analyzes the forms of impact of non-design loads from shock air waves on building structures. The problem of forecasting the dynamics of the explosive load on a building structure (for example, the covering of a buried structure) is solved by the simultaneous solution of the equation of the spatial distribution of excess pressure in the front of a shock air wave and the dependence of the time of its action on the speed of its front. Since the speed of the shock air wave is constantly changing, the equation of the time of the wave action has a differential form, and its solution is established on the assumption that the simultaneous action of the wave on the surface of the building structure occurs on an area that is limited by the width of the shock wave front. On the basis of this, a grapho-analytic technique for determining the spatio-temporal dependence of the change in excess pressure in the plane of the building structure at the time of impact of the shock wave was developed. This dependence is established in the form of a table or graph, which is a loading curve.

Cyberbullying among University Students: A Study on Sri Lankan Universities
Authors: Inthusha K. , Kajananthan R.
Published: September 2024

Cyberbullying serves as a channel through which individuals who have faced victimization during their university experience can vent their anger and frustration. This study delves into the determinants influencing cyberbullying among university students. We collected and analyzed 150 relevant responses from university students in the Sri Lankan context, employing multiple regression analysis. The findings reveal that social influences, social media usage, internet addiction, social anxiety, and trait anger significantly impact cyberbullying behaviors. However, it is essential to note that this study is confined by its focus on only five variables and a sample limited to Sri Lankan state university students. Despite these constraints, our research enriches the understanding of cyberbullying dynamics, advocates for heightened awareness among students, authorities, government bodies, and other stakeholders, and offers recommendations to promote online safety and combat cyberbullying.
Customer Insight to Digitalisation and Open-Banking in Nigeria

Published: September 2024

The business world is experiencing rapid technological integrations. Several innovations have contributed to the success of businesses as the customer continues to play a strategic role in innovation’s acceptance or rejection. Open banking is a disruptive innovation that represents a departure from the traditions in emerging markets where financial inclusion has been focused on the consumer. It is rapidly being adopted in developed economies with developing economies such as Nigeria and India making incursions in adopting the innovation. Its ability to impact the business environment and improve access to financial services depends on customers’ consented data thereby making customers significant to its success. The challenge is on rising data privacy violation and data leakage. The purpose of the study is to examine the determinants of the success of open banking in Nigeria from customers’ perspective. The study is a novel study in Nigeria following the focus of extant studies on application and challenges of the innovation. Cross-sectional survey, case study analysis and close-ended questionnaire were adopted in the study while structural equation modeling was employed in analysing the data. The findings revealed that customers consent to open banking is positively influenced by the direct effects of compatibility and customers’ perception of security and trust. Also, the success of the innovation is impacted by the negative link between perceived access, perceived risk and customers consent to open banking. The significant result of the indirect relationships also justifies the importance of these variables in ensuring the success of open banking in Nigeria. With this, emphasis is on strategic management and policy drives that ensure effectiveness and protection of customers.

Published: September 2024

In the dynamic landscape of leadership development, cultivating future leaders requires a strategic focus on instilling brand knowledge as a powerful tool. Recognizing the profound impact that brand awareness can have on shaping the younger generation, this approach goes beyond traditional leadership training. It emphasizes the importance of understanding and embodying the values, ethos, and narrative of a brand, empowering emerging leaders to navigate complexities with authenticity and purpose. This integration of brand knowledge not only equips them with a strong foundation for decision-making but also fosters a sense of identity and commitment, ultimately contributing to the development of visionary and impactful leaders poised to shape the future. The conceptual model was developed based on four main variables, namely Brand Knowledge Acquisition, Leadership Development Programs, Digital Literacy and Social Media Engagement to Leadership Effectiveness with Brand Integration and Education Level. For analyzing purposes, data was collected from a representative sample of 200 both male and female individual who were aged between 16 to 28 from Colombo metropolitan. A self-administered questionnaire was used for data collection. SPSS version 25 statistical package was used for data analysis. The findings of the study conclude that Brand Knowledge Acquisition, Leadership Development Programs, Digital Literacy and Social Media Engagement have significant impact on Leadership Effectiveness with Brand Integration. And also, Education Level moderate the relation between the power of brand knowledge and Leadership Effectiveness with Brand Integration.
Low ozone concentrations do not exert cytoprotective effects on tamoxifen-treated breast cancer cells in vitro

Published: September 2024

Medical treatment with low ozone concentrations proved to exert therapeutic effects in various diseases by inducing a cytoprotective antioxidant response through the nuclear factor erythroid derived-like 2 (Nrf2) transcription factor pathway. Low ozone doses are increasingly administered to oncological patients as a complementary treatment to mitigate some adverse side-effects of antitumor treatments. However, a widespread concern exists about the possibility that the cytoprotective effect of Nrf2 activation may confer drug resistance to cancer cells or at least reduce the efficacy of antitumor agents. In this study, the effect of low ozone concentrations on tamoxifen-treated MCF7 human breast cancer cells has been investigated in vitro by histochemical and molecular techniques. Results demonstrated that cell viability, proliferation and migration were generally similar in tamoxifen-treated cells as in cells concomitantly treated with tamoxifen and ozone. Notably, low ozone concentrations were unable to overstimulate the antioxidant response through the Nfr2 pathway, thus excluding a possible ozone-driven cytoprotective effect that would lead to increased tumor cell survival during the antineoplastic treatment. These findings, though obtained in an in vitro model, support the hypothesis that low ozone concentrations do not interfere with the tamoxifen-induced effects on breast cancer cells.

Community support is known to play an essential role in enhancing maternal health during pregnancy. This is primarily due to the influence of societal factors on the health status of both the mother and fetus. In addition, the significance of community support is particularly evident in the Gorontalo community of Indonesia due to the influence of socio-cultural factors. This study aims to analyze the extent of culture-based Gorontalo community support for short-term pregnant women in improving maternal health and preventing stunting neonates.The procedures were carried out using a qualitative study method with a phenomenological approach. The sample population comprised 12 pregnant women, 9 village midwives, and 6 cadres, who were selected using the snowball sampling method. In addition, data collection was carried out through in-depth interviews and observations, followed by analysis using Interpretive Phenomenology Analysis (IFA).The people of Gorontalo were very supportive and concerned about the health of short-term pregnant women and fetuses to prevent stunting neonates. A form of culture-based community support comprised regular reminders to pregnant women to diligently attend monthly check-ups with both traditional healers and healthcare professionals. Traditional healers, also known as shamans, fulfilled their role by performing a range of rituals believed to enhance health and well-being. These rituals typically included massages, administering water fortified with sacred chants, and conducting monthly ceremonies for 7 months. In addition, community members frequently offered food preferences to pregnant women and provided reminders to avoid taboos.In summary, community support deeply rooted in culture can serve as a powerful reminder for expectant mothers to undergo regular check-ups with both traditional healers and healthcare professionals on a monthly basis.

Hypertension is a prevalent chronic condition that requires effective self-management strategies for optimal control and complications prevention. Self-management interventions have become a crucial component in the management of hypertension. Therefore, this review aimed to determine effective self-management strategies for hypertensive patients.Articles were searched from four databases, namely Science Direct, Ebsco (MEDLINE), Proquest, Pubmed and Sage Journals based on PRISMA guidelines. The search included articles published in English between 2013 and 2022. A key term search strategy was adopted using “self-management interventions”, “nursing interventions”, “experimental study” and “hypertensive patients” to identify relevant studies.The results showed that self-management interventions have been proven to have positive effects on various aspects of hypertension self-management, including blood pressure monitoring, disease knowledge, medication adherence, and lifestyle modifications. These interventions can be delivered through technology-based platforms. Moreover, there are different types of self-management interventions for hypertensive patients, including individual and group approaches, the use of technology, nursing theory, and interventions based on the cultural aspects of patients.To conclude, as professionals, nurses should be able to determine which self-management strategies are suitable for the conditions and requirements of patients.

The knowledge about nutrition in children is essential for parents, who play a significant role in ensuring proper growth and development. Many parents lack awareness about proper maintenance of nutrition for children. Therefore, this study aimed to evaluate the effect of peer education on parental knowledge about the nutritional status of children.A pre-experimental method was used and respondents comprised 20 parents of students from elementary school in Palembang City. Data was collected using a questionnaire before and after the intervention.The result showed that there was an increase in parental knowledge with a p-value =0,001 according to the Wilcoxon test. The mean values before and after intervention were 16.8 and 21.8, respectively. Intervention through peer education improved parental knowledge about achieving balanced nutrition in children. Parents were also empowered to share information with others regarding the knowledge obtained through trusted sources. This information entailed nutritional status, appropriate nutrient uptake, and optimized physical activity for children.The integration of peer education resulted in a substantial increase in the average level of parental knowledge after the intervention.

Adolescents’ unstable personalities are responsible for poor behavioral choices, which adversely affect their quality of life. Therefore, this study aimed to examine health-related behaviors, such as drinking and smoking, alongside demographic characteristics and basic health knowledge.A total of 100 adolescents aged 11 to 20 were randomly selected as respondents using a cross-sectional observational analytical method. Data collection relied on interviews, which were subjected to univariate analysis using logistic regression and Chi-Square tests.The results showed that there was a significant correlation (p-value 0.003) between smoking and reproductive health behaviors. However, no significant correlation (p-value 0.410) was found between reproductive health behaviors and alcohol consumption.In conclusion, the research uncovered a significant correlation between smoking and reproductive health behaviors. It was necessary to instill healthy lifestyle skills in adolescents early on to deter them from engaging in risky health behaviors.

Novice nurses play a workflow part in responsibility among an overwhelming of patient. This emphasizes the need for nurses to have comprehensive decision-making skills, especially in disaster management. However, in practice, clinical decision-making remains a challenging issue for novice nurses working in the Emergency Room (ER). This review was conducted to synthesize the strategy that novice nurses need to do in clinical decision-making in the ER during a disaster.This review used an integrative literature review approach to identify (n=16) relevant scientific articles. Six online databases (ScienceDirect, Proquest, Sage Journals, PubMed, Willey Library, and EBSCO) were utilized to identify articles published between 2013 and 2023. The gathered articles were selected using the PRISMA method by removing duplicate articles and those that did not align with the review's objectives. The PRISMA flowchart was used to illustrate the evidence search process. Out of a total of 2,264 identified articles, sixteen articles are relevant for review.The review revealed that clinical decision-making requires careful consideration in several aspects which focused on determining the priorities of triage, assessment, diagnostic skills, and communication skills in teamwork during a disaster in the ER. This review provides evidence that the accuracy of clinical decision-making is a major influence on patient outcomes during disaster management.In conclusion, comprehensive training and more education for novice nurses about disaster precision nursing in the future are needed to reduce errors in decision-making.
On probiotic integration in the management of inflammation and the maintenance of the intestinal epithelial barrier’s integrity
Authors: Traina Giovanna
Published: September 2024

Inflammatory bowel disease epidemiology has grown dramatically in recent years, particularly in developed and developing Western countries. Many factors, including stress, diet, and medications, cause and exacerbate inflammatory conditions. Inflammation is closely related to the concept of intestinal barrier integrity. When integrity is compromised, toxins and pathogens can enter the bloodstream. In recent years, there has been a growing interest in using probiotic bacteria to prevent or treat a variety of pathologies, including inflammatory bowel disease. Some studies have looked at the effectiveness of multi-strain probiotic supplements in preventing intestinal barrier dysfunction in in vitro models of lipopolysaccharide-induced inflammation. To mimic the intestinal barrier, human colon adenocarcinoma cell lines were established in Transwell co-culture models. The epithelium permeability was assessed by measuring the transepithelial electrical resistance. The expression of individual proteins involved in barrier function was assessed. The immunomodulatory effects of probiotic formulations were studied in both human macrophage cell lines and ex vivo human peripheral blood mononuclear cell-derived macrophages. The intestinal epithelial layer was also interfaced with a human mast cell line. Selected probiotics have demonstrated high potential for use in maintaining intestinal barrier integrity and possessing anti-inflammatory properties.
