Size structure, sex ratio, and breeding season in two intertidal grapsid crab species from Mar Chiquita Lagoon, Argentina
Authors: Spivak Eduardo D , Anger Klaus , Bas Claudia C , Luppi Tomás A , Ismael Deborah
Published: November 2024

Life history patterns of two grapsid crab species were studied in Mar Chiquita, a brackish coastal lagoon in Argentina. Chasmagnathus granulata is a burrowing crab living in the upper intertidal, whereas Cyrtograpsus angulatus lives predominantly in the lower intertidal and subtidal. C. granulata is active (i.e. foraging and reproducing) during spring, summer and most of autumn, but remains mostly hidden inside its burrows during winter. Two dominant size groups each were found in the size-frequency distributions of males and females. Since this species builds elaborated and rather stable burrows, we found a rather uniform spatial distribution and a stable sex ratio, with only weak local deviations from a 1:1 ratio. In C. angulatus, which is a very mobile species, the sex ratio varied greatly in time and space, indicating local migrations with differential intensities or directions in males and females. Adult size structure in this species was similar at different sampling sites, with size frequency distribution of males revealing three dominant size groups, but that of females only one or two. In late autumn, most individuals of this species leave the intertidal zone and stay during winter in deeper water. Both species show a pronounced seasonal reproductive activity pattern, with a maximum percentage of ovigerous females found in the beginning of summer, and both appear to produce several subsequent egg clutches until late summer. The reproductive season is longer in C. angulatus (September-May; a few ovigerous females were found also in winter) than in C. granulata (October-March). In the intertidal, a low percentage of C. angulatus was observed to carry eggs in late embryonic stages. This suggests that ovigerous females of this species may migrate to the subtidal to release their larvae in deeper water.

Marés meteorológicas no litoral do estado do Paraná: o evento de 18 de agosto de 1993
Authors: Marone Eduardo , Camargo Ricardo de
Published: November 2024

Este trabalho é um estudo de caso relativo ao fenômeno da maré meteorológica ocorrida em 18 de agosto de 1993 na costa sudeste brasileira, com ênfase no Estado do Paraná As causas deste evento, caracterizado por grandes elevações do nível médio do mar e, em algumas regiões pela ação de grandes ondas de superfície, como em Matinhos, foram estudadas através de cartas sinóticas de pressão atmosférica à superfície e de imagens do satélite METEOSAT-4. Foram usados dados de alturas do nível do mar obtidas no Porto de Paranaguá e observações meteorológicas do Centro de Estudos do Mar (CEM) da Universidade Federal do Paraná (UFPR), em Pontal do Sul, para ilustrar a situação no continente. A principal causa deste aumento do nível do mar foi o vento associado à combinação da passagem de uma frente fria pelo oceano e de um centro de alta pressão pelo continente, aumentando a área oceânica sob a ação de ventos do quadrante sul. No sudeste do Brasil estes ventos acumulam água na costa devido ao transporte de Ekman. Além disso, a transferência de momento da atmosfera para o oceano em locais de grande profundidade gerou grandes ondas que tiveram fortes efeitos destrutivos na zona costeira. Apesar do número de frentes frias ser maior durante o invemo, não se pode afirmar que ressacas não ocorram em outras épocas do ano. Os fatores que propiciam este fenômeno não estão diretamente relacionados com as estações do ano.

Published: November 2024

O objetivo deste trabalho foi verificar a distribuição batimétrica, freqüência e dominância dos anomuros da plataforma continental do Cabo Frio, além de aspectos biológicos de Dardanus arrosor insignis. Utilizando-se uma rede de porta de 10 m de abertura com malha de 1 cm no fundo do saco, foram realizados arrastos mensais de 20 minutos, nas profundidades de 30, 45 e 60 m, em frente à praia da Maçambaba em Arraial do Cabo, de janeiro de 1986 a dezembro de 1988. Foi registrada a temperatura e salinidade da água junto ao fundo. As conchas de moluscos ocupadas por Dardanus arrosor insignis foram identificadas. Foi registrado o número de femeas ovígeras. Foram encontradas 8 espécies, sendo a maior riqueza e abundância a 45 m. Nas três profundidades, a espécie dominante foi Dardanus arrosor insignis. A distribuição de freqüência de tamanho dos machos variou entre 0,4 e 6,5 cm, enquanto as femeas variaram de 0,4 a 4,6 cm. Foram encontradas femeas ovígeras entre 1,0 e 1,9 cm, entre agosto e dezembro. Foi mais utilizada a concha de Buccinanops moniliferum. Não foi encontrado um padrão sazonal no número total de indivíduos. No entanto, pareceu haver uma relação entre os períodos de maior abundância de Dardanus arrosor insignis e temperaturas abaixo de 18°C (águas de ressurgência).

Authors: Athayde Simone Ferreira de , Tomaz Lea Maria
Published: November 2024

O trabalho foi realizado na Ilha do Mel (coordenadas 25°29’ S e 48°2r 18” W) em maio e junho de 1995, visando levantar as relações existentes entre a comunidade de moradores e as áreas protegidas da região, que somam cerca de 93% da área total da Ilha. Foram realizadas 52 entrevistas (cerca de 39% do público-alvo) com adultos (maiores de 18 anos) moradores em 3 comunidades da parte norte da Ilha, através de questionário abordando aspectos sócio-econòmicos, relação homem e ambiente e relações específicas com as áreas protegidas: Estação Ecológica e Reserva Natural. Quase todos os entrevistados, classificados em nativos e não nativos da Ilha, dedicam-se a alguma atividade econômica ligada ao turismo, principal atividade econômica do local. A função de proteger o solo da ação do mar foi o aspecto mais destacado com relação à importância da floresta. Este fato relaciona-se a uma característica local, tendo-se em vista que a erosão causada pela ação do mar vem ocorrendo na Ilha mais intensamente a partir de 1936 e que muitas pessoas perderam casas e terrenos em decorrência deste fenômeno. As principais categorias de importância levantadas para a floresta e o manguezal foram o uso direto e indireto dos recursos (como por exemplo madeira e caranguejos). Quanto às áreas protegidas, a maior parte das respostas obtidas (44%) indica um desconhecimento sobre a importância e finalidade de sua existência. Alguns dos problemas levantados com relação à existência destas referem-se à uma restrição aos costumes tradicionais da comunidade, além da impossibilidade da obtenção futura de lotes pelos nativos. Destaca-se porém, que a maior parte das respostas obtidas (46%) indica que as áreas protegidas não estão relacionadas com os problemas cotidianos dos moradores. Com os resultados obtidos, são indicadas algumas estratégias de ação visando contribuir ao futuro gerenciamento da região pela integração necessária entre turismo, conservação e participação comunitária.

Published: November 2024

During the entire month of July 1995 an international “Advanced Course on Marine Zooplankton Ecology” was held at the Centro de Estudos do Mar (CEM) of the Universidade Federal do Paraná in Pontal do Sul, Paraná, Brasil. This course included 13 students (listed in Table 1) from five Latin American countries (Argentina, Brasil, Chile, Ecuador and Mexico), and instructors from Brasil (Bjomberg, Brandini and Lopes), Germany (Bathmann) and the United States (Turner) (Photo 1). Because this experience was scientifically as well as culturally enlightening, for both students and instructors, we briefly summarize significant aspects of this effort, in the hope that our course might serve as a model for similar endeavors which might be attempted elsewhere.
Finding the Nexus between Gender-Based Violence and Conservation
Authors: Kogada John Okandi
Published: November 2024

This review paper explores the complex and multifaceted relationship between gender-based violence (GBV) and conservation efforts, emphasizing the interconnected challenges faced by rural communities. It analyzes how GBV undermines conservation outcomes by limiting women’s participation, eroding traditional ecological knowledge, exacerbating resource exploitation, and weakening community resilience. Drawing on case studies from Northern Ghana, India, and Tanzania, the paper highlights how environmental issues such as resource scarcity, displacement, and conservation-related conflicts increase the vulnerability of women to GBV. The review also discusses strategies for addressing these challenges, including empowering women, integrating gender considerations into conservation policies, and creating safe environments for participation. Finally, it calls for more research into the links between GBV and conservation, urging the development of targeted interventions that address the root causes of both GBV and environmental degradation. By integrating gender-sensitive approaches, conservation initiatives can achieve more equitable and sustainable outcomes for all community members.

Authors: Lu Jinying , Chang Taotao , Hao Mingming , Liu Lijuan , Yin Zhanru
Published: November 2024

Objective: This study investigates the effects of a hierarchical chain nursing model on the resolution time for fever and cough in children diagnosed with pneumonia. Methods: Eighty children with pneumonia admitted to our hospital between March 2021 and January 2022 were enrolled in this study. The participants were divided into two groups: the observation group and the experimental group, each containing 40 patients, based on the nursing interventions provided. The observation group received standard nursing care, while the experimental group was treated with the hierarchical chain nursing model. We compared clinical outcomes, including the resolution times for symptoms (fever, cough, pulmonary rales), length of hospitalization, pulmonary function indicators [such as peak expiratory flow (PEF), functional residual capacity (FRC), and forced expiratory flow rate at 25% of vital capacity (FEF25%)], the mental health of family members, and their satisfaction with nursing care. Results: The total effective treatment rate was 77.5% in the observation group and 97.5% in the experimental group, with the latter significantly higher (P<0.05). The duration of pulmonary rales and the length of hospitalization were significantly less in the experimental group (all, P<0.05). Post-intervention, the levels of PEF, FRC, and FEF25% showed substantial improvement in the experimental group compared to the observation group (all, P<0.05). Moreover, the Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) scores for family members in the experimental group were significantly lower than those in the observation group (all, P<0.05). Family satisfaction rates were 75.0% for the observation group and 97.5% for the experimental group, with the latter demonstrating significantly greater satisfaction with nursing care (P<0.05). Conclusion: The hierarchical chain nursing model proves to be highly effective in managing pneumonia in children. This model not only enhances clinical outcomes and expedites the resolution of symptoms such as fever, cough, and pulmonary rales but also improves lung function and reduces psychological stress among family members. Consequently, this model significantly increases family satisfaction with nursing services.

Authors:   University of KwaZulu-Natal, Magidimisha H.H. , Mutombo B.I.S , Viramuthu C.
Published: November 2024

This paper explored the implications of residential gated communities in KwaDukuza municipality. Qualitative research method was adopted to respond to the objectives of the study. Findings revealed that these communities contribute to social and spatial segregation, hindering integrated development efforts and contradicting the principles of the Spatial Planning and Land Use Management Act (SPLUMA), which aims to address apartheid-era inequalities. The study also noted potential negative effects on environmental sustainability. Despite these issues, homeowner associations have improved local services like security and waste management, benefiting the community. Factors driving the growth of gated communities include security, quality services, and social status. However, they pose challenges for local authorities by obstructing the municipality’s spatial vision outlined in the Spatial Development Framework and Integrated Development Plan. Therefore, establishing a regulatory framework for gated community development is recommended to prevent further segregation and manage their expansion.
REIMAGINING SOUTH AFRICA’S URBAN FOOD SECURITY AND NUTRITION THROUGH THE LENS OF INFORMAL FOOD SECTOR: THE CASE OF BUFFALO CITY MUNICIPALITY
Authors:   University of KwaZulu-Natal, Masuku B. , Khalema E.N. ,   University of KwaZulu Natal
Published: November 2024

The African Food Security Urban Network (AFSUN)survey found that over 70% of low-income households in South Africa sourced their food from informal outlets. Despite the importance that the informal food retail sector plays in food security, it remains neglected by policy support and institutional funding. The paper focused on the role of local informal food markets in addressing urban household food security in Buffalo City Municipality (BCM), South Africa. This paper argued that informal food markets including food vendors have a potential to improve household food insecurity levels but face many barriers. The study sought to identify these barriers and make an understanding of how these local food markets adopt coping mechanisms in meeting their basic needs including addressing household food insecurity. A qualitative approach was adopted for this study. Data was collected from 40 food vendors, particualrly street vendors and home-based enterprises in the township of Duncan, through interviews, observations, and archival research. Interviews included semi structured interviews to gather insights from street vendors, while interviews with city officials provided key informant perspectives. This study’s findings show that households without access to networked infrastructure use informal food markets as: (i) a food source, (ii) a food kitchen and a cookstove and (iii) a refrigerator, to purchase their foodstuff and other ready-to-eat meals.

Published: November 2024

The use of cross-laminated timber (CLT) panels has increased significantly, driven by the demand for more sustainable structural solutions. When used in short spans, the load capacity of CLT panels can be significantly enhanced; however, their behaviour and failure mechanisms differ from those of large spans. This study evaluates the mechanical behaviour of short-span CLT panels made from Pinus taeda L. under out-of-plane loads, through experimental analyses on full-scale panels. Fourteen industrially manufactured panels were tested in four-point bending tests, using adhesive weights of 250 and 220 g/m². The values of maximum bending moment, shear force, and their respective resistances were analysed based on the observed failure modes. The transverse modulus of elasticity was determined using strain gauges. It was found that short panels, with a span-to-depth ratio of 9 ≤ l/h ≤ 12, exhibited bending moment and shear force failures, with no significant differences between adhesive weights. Discrepancies in shear resistance and stiffness values compared to existing standards suggest the need for reduced-specimen testing for greater accuracy.

Authors: Fernandes Tatiane dos Santos , Romero Adriano Lopes
Published: November 2024

Partindo da premissa que a experimentação é um recurso didático que contribui de forma significativa para o processo de ensino e aprendizagem de Ciências, em especial o de Química, e que nem todos os conteúdos escolares de Química são abordados por meio da experimentação. O presente trabalho teve como objetivo responder a seguinte pergunta: A experimentação tem sido empregada como recurso didático para o ensino e aprendizagem do conteúdo escolar elementos químicos na Educação Básica? Para responder a essa pergunta, realizou-se uma revisão sistemática da literatura, utilizando a metodologia PRISMA, em três bases de dados: Portal de Periódicos da Capes, Biblioteca Digital Brasileira de Teses e Dissertações, e o Catálogo de Dissertações e Teses da Capes. Aplicados os critérios de inclusão e exclusão, o corpus textual foi constituído de seis trabalhos, sendo quatro dissertações e dois artigos em periódicos. Os estudos enfatizam a importância da experimentação, mas também exploram outras estratégias metodológicas no processo educacional, como vídeos, histórias em quadrinhos e atividades em museus. Há um esforço coletivo para promover uma abordagem crítica e interdisciplinar, transcendendo a dicotomia teoria e prática.

Published: November 2024

O Programa de Educação Tutorial (PET) integra ações de ensino, pesquisa e extensão, aprimorando a formação universitária. Alinhado às Diretrizes Curriculares Nacionais Farmacêuticas (DCNs), e sob a orientação de docente tutor, o PET-Farmácia da Universidade Federal do Paraná (UFPR) promove atividades complementares de pesquisa explorando temas como fitoterápicos emergentes. O Tribulus terrestris L. (TT) é uma espécie de crescente destaque no segmento fitoterápico, exigindo dos farmacêuticos conhecimentos sobre propriedades, evidências de saúde, riscos e segurança associados ao uso. Este trabalho tem como objetivo descrever características, propriedades e evidências científicas associadas ao uso de TT como fitoterápico, identificando lacunas nas DCNs onde possam complementar o ensino farmacêutico. A metodologia utilizou revisão narrativa da literatura com abordagem qualitativa, retrospectiva e exploratória. Utilizou-se as bases de dados PubMed, Scopus e Web of Science, sendo identificado 180 estudos, dos quais 25 selecionados para análise completa após a exclusão de duplicatas e estudos não relacionados. As informações coletadas foram apresentadas ao grupo PET-Farmácia UFPR e confrontadas às Diretrizes Curriculares dos Cursos de Farmácia, destacando-se lacunas nas quais o estudo de TT poderia complementar a formação acadêmica. Os resultados indicam que TT apresenta propriedades como efeitos antioxidantes, antitumorais, anti-inflamatórios e moduladores da testosterona. Porém, há fragilidade nas evidências, sobretudo quanto ao uso eficaz como suplemento ergogênico e para disfunções sexuais. A avaliação das diretrizes curriculares demonstra que o estudo de TT pode complementar conteúdos sobre metodologia científica, fitoquímica, farmacognosia, farmacologia, entre outros. Esse trabalho destaca a educação tutorial como ferramenta capaz de complementar a formação farmacêutica.

Authors: Duan Jia , Fadri Rodil F.
Published: November 2024

The study assessed the school innovation culture and teachers' research competence in selected higher education institutions in Hunan, China. It assessed the culture of school innovation using the sub-variables strategy, support mechanism, structure, and creative behavior. To assess research competence, the study used the sub-variables research methodology, ethics, and utilization of research. The study also determined the predictive role of innovation culture on teachers' research competence. The study involved 305 teacher respondents selected randomly from a total population of 1460 teachers. The researcher developed the instrument used for data gathering. It was validated, pilot tested, and showed acceptable reliability results. The findings revealed a weak innovation culture in the schools investigated. The respondents assessed innovation culture as weak in all its sub-variables. It implies a lack of organized effort to foster an innovation culture in the investigated schools. The findings also showed poor research competence among the respondents. They have poor competence in research methodology, ethics, and utilization. Based on the results of the multiple linear regression analysis, the study concluded that school innovation culture has a predictive influence on teachers' research competence. This implies that a weak school innovation culture has a negative impact on the research competence of teachers. The study highlights the need to strengthen innovation culture to increase school research productivity.
Immunological Insights into Healthy Aging: The Impact of BCG Vaccination
Authors: Bulut Özlem
Published: November 2024

Maintaining a robust immune system is key to healthy aging. This thesis explores how the immune system changes with age and proposes ways to counteract it. The first part showed that individuals from Tanzania and the Netherlands experience immune aging differently, partially due to diet. We identified multiple molecules linked to a stronger immune system in old age and showed that immune aging differs for men and women. The second part focused on counteracting immune aging by inducing “trained immunity”: the immune system's memory of past exposures resulting in a better response to future threats, even if they differ from the original. BCG vaccination is a safe way to induce trained immunity. Our studies identified a natural compound that improves BCG’s effect and a common osteoporosis medication that suppresses it. Overall, this work provides new insights into promoting a healthy immune system in older adults.

Published: November 2024

A provenance trial involving 50 provenances of Acacia catechu from the state of Himachal Pradesh was laid out at the Regional Horticultural Research Station at Jachh in the year 1988 to evaluate their performance for further afforestation programmes. The results indicated significant variation in growth performance of different provenances. The 20 best performing provenances were selected in the year 1998 and the above ground biomass was determined by felling sample trees. The height and diameter ranged from 6.02-8.85 cm and 8.45-14.11 cm respectively. The provenances, viz., P15 (Parwanoo-5), P10 (Sadar Bilaspur-4), P13 (Subathu-5) and P14 (Nurpur upper –2) produced the highest above ground biomass.

Published: November 2024

A study was conducted to estimate the soil organic carbon and microbial biomass carbon contents at various altitudes in a pine forest in the Kumaon hills of the N.W. Himalayas. Soil samples from the surface and sub-surface layers were analyzed for pH, soil organic carbon and microbial biomass carbon contents. The highest soil organic carbon content of 1.42% and microbial biomass carbon content of 128.12 µg g-1 were observed in the surface layers at the lower reaches of the pine forest (1270 m amsl). Within the various altitudes chosen for the study the surface soils of the pine forest had higher content of organic carbon and microbial biomass carbon when compared to the subsurface soil in most cases. This study has clearly proved that variation exists in the organic carbon and microbial biomass carbon at varying altitudes within a pine forest.

One of the traditional problems in survey sampling is to estimate the population parameter like mean variance etc. This article investigates the mathematical derivations and application of neutrosophic statistics to address the challenges posed by imprecise, indeterminacies or ambiguous data, such as daily stock prices, weather forecast, social media sentiment and temperatures. The suggested estimators are highly useful for computing results while working with unclear, hazy, and neutrosophic-type data. These estimators produce answers that are interval-form rather than single-valued, which may give our population parameter a better chance of being off. We propose three novel neutrosophic exponential ratio-type estimators for the population mean, utilizing information of neutrosophic auxiliary variables. Expressions for bias and mean square error (MSE) of these estimators are derived using first-order approximations to assess their performance in terms of accuracy. To demonstrate their effectiveness, we apply the proposed estimators to real-life neutrosophic data sets. Additionally, a simulation study shows that our estimators outperform existing methods in terms of MSEs and percentage relative efficiency (PREs). This study further expands its originality by including pre-existing estimators into the neutrosophic framework, showcasing its versatility and adaptability. The results suggest that neutrosophic statistics provide a robust framework for analyzing uncertain data, facilitating more reliable decision-making in various applications.

Authors: Geng Xiaonan
Published: November 2024

This paper explores the socioeconomic impact of Nigerias high fertility rate and its influence on the countrys economic development. With a fertility rate of 5.14 children per woman in 2022, far exceeding the global average, Nigeria faces significant demographic challenges. The analysis focuses on three critical data points: fertility rate, female tertiary education rate, and female labor force participation rate. The findings highlight how cultural factors, educational attainment, and labor market participation contribute to sustained high fertility rates, particularly in rural areas. Additionally, the paper examines how these factors exacerbate gender inequality and limit economic opportunities for women, thereby hindering Nigeria's overall economic progress. Policy recommendations include promoting female education and workforce participation to help manage population growth and stimulate economic development.
