Sheep farming faces significant health challenges, particularly from gastrointestinal nematodes like Haemonchus contortus, which can severely impact animal health. In response, there is growing interest in herbal medicines derived from medicinal plants as alternative solutions for parasite control. This approach offers multiple benefits, including local availability, reduced risk of anthelmintic resistance, decreased dependency on synthetic chemical treatments, and improved shelf life. Among the promising alternatives, Morinda citrifolia has shown potential for effective nematode control. This study evaluates the anthelmintic efficacy of the hydroalcoholic crude extract (EHMC) of Morinda citrifolia using a clustering approach based on an Artificial Immune/Neural System to determine the optimal dosage. The findings reveal that the EHMC of Morinda citrifolia inhibits the hatching of Haemonchus contortus eggs, increases the mortality of adult nematodes, and demonstrates anthelmintic activity in lambs without causing adverse effects on animal health or negatively impacting meat quality. This suggests that Morinda citrifolia extract is a promising natural alternative for controlling parasitic infections in sheep.

The food-energy-water (FEW) nexus framework calls for a systems perspective on addressing complex sustainability challenges. As a sustainability science field, nexus research should in theory bring together transdisciplinary approaches drawing from a range of stakeholder knowledge and experiences. This approach would align with the competence-based training for future sustainability leaders advocated for in sustainability education literature. In practice, the field is dominated by techno-scientific approaches with superficial or peripheral attention paid to issues of social justice and community engagement. In this article, we explore how this imbalance in the literature reflects a breakdown between the ideals of sustainability training and the reality of training at the nexus and describe obstacles that may be contributing to this breakdown, including a prejudice towards the idea of "objective" science, institutional incentives, and disciplinary culture. To address these concerns, we introduce a research project focused on assessing the training of future researchers at the FEW nexus and exploring how these programs train students in particular views of what is important at the FEW nexus, such as technological solutions, stakeholder collaboration, and/or issues of equity and justice. It will also provide recommendations for creating open learning environments that are competence-based, and that incorporate multiple methods, acknowledgments of limitations, and alternate ways of knowing.

This study identifies determinants of the variation in depression resulting from COVID-19, specifies in detail the changes to daily life, and then compares the determinants' magnitude. The determinants were combined into three groups: first, the unpredictability of the disease and side effects by its response measures (specifically, restrictions on the freedom of movement and strain on social relationships);second, (mis)information through social media, public authorities, and mass media;and third, income reductions and other sociodemographic factors. Daily life changes were divided into four categories: travel/mobility, time at home (alone and with family), domestic activities (remote work, online shopping, food deliveries, reading, and online networking), and conflicts (with family and neighbors). We measured the total 29 predictors using data from the 2020 Seoul Survey, which is based on face-to-face interviews with a probability sample of adult residents. We made our estimations using partial least squares regression, which can analyze all original variables regardless of collinearity. The regression model found that major stressors include declines in out-of-home offline networking and the rise of domestic activities-and subsequent conflicts with family-restrictions on mobility (specifically, those of leisure travel), and income reductions. In contrast, changes to working and shopping (to remote work and online shopping) rather than leisure increased uses of private transportation modes. Moreover, we found influences of all forms of communications and media to be insignificant. We shall also provide a discussion on policy and academic implications of the findings.

The centralised regime and variation of resources have led persistent regional disparities in Indonesia. Presently, there is lack of study that examines the impact of agglomeration economies and technology of firm establishment on regional growth in Indonesia. This paper applies agglomeration economies, approximated using proxy variables of concentration of four largest sectors (CR4), specialisation (LQ), diversity (DIV) and competition (COM) variables and technological capacity, approximated by total factor productivity (TFP), to explain the impact of firm establishment on economic growth. The paper found that districts with less specialisation and more advance technology would have higher economic growth. The paper recalls the importance of higher share of high-tech industry and a more spatial dispersion of industry to accelerate economic growth.

Objective: Increased point prevalence rates of oppositional defiant disorder and conduct disorder have been reported in American Indian and Canadian First Nations children and adolescents. To date, in Australia, there has been no published examination of standardized Diagnostic and Statistical Manual mental disorder diagnoses in First Nations children and adolescents, determined after addressing key cultural methodological issues. Methods: In all, 113 First Nations children and adolescents and 217 non-First Nations young people, aged 6-16 years, age, gender, mental disorder symptom severity, symptom-linked distress and impairment matched were recruited in a case control study. Also, 112 typically developing non-First Nations participants, age and gender matched to the other two clinical groups as a second comparison group were recruited. Diagnostic and Statistical Manual mental disorder diagnoses via semi-structured clinical interview, social adversity status and full scale IQ were determined in all participants with cultural validity and reliability of the impairing patterns of symptoms in First Nations young people determined by First Nations mental health staff and Aboriginal Health Liaison Officers. Full scale IQ and social adversity status were appropriately controlled in the Logistic Regression analyses of Diagnostic and Statistical Manual mental disorder diagnoses between the two clinical groups. Results: Oppositional defiant disorder was the only diagnostic and statistical manual mental disorder diagnosis that differed between the First Nations and non-First Nations clinical groups, adjusting for confounding by social adversity status and full scale IQ in the multivariable model. The point prevalence of oppositional defiant disorder was 2.94 times higher (95% confidence interval: 1.14-7.69) among the First Nations compared to the non-First Nations clinical group. Conclusion: Key known risk factors for oppositional defiant disorder can be identified early and

In this article, optimal energy consumption in the smart houses is studied considering techno-economic indices and demand side management (DSM) in electrical grids. The optimal energy consumption is implemented based on optimal scheduling of the household appliances than energy price and capacity of demand flexibility in DSM. The proposed approach is considered as two-stage optimization. Using first stage, energy consumption is modified by optimal shifting of the appliances subject to DSM and energy price. Thus, modified energy consumption is taken into accounted in second stage optimization to maximizing the consumers comfort and minimizing operation cost, simultaneously. The optimization process is done in the MATLAB software, in which objectives in second stage are optimized via Ip-metric method. Finally, the performance of the proposed modelling is validated as case studies using numerical simulation.

Palm vein recognition has relevant advantages in comparison with most traditional biometrics, such as high security and recognition performance. In recent years, CNN-based models for vascular biometrics have improved the state-of-the-art, but they have the disadvantage of requiring a larger number of samples for training. In this context, the generation of synthetic databases is very effective for evaluating the performance of biometric systems. The present study proposes a new perspective of a transfer learning approach for palm vein recognition, evaluating the use of Synthetic-sPVDB and NS-PVDB synthetic databases for pre-training deep learning models and validating their performance on real databases. The proposed methodology comprises two different branches as inputs. Firstly, a synthetic database is used to train a CNN model, and in the second branch, a real database is used to finetune and evaluate the performance of the resulting pre-trained model. For the feature learning process, we implemented two end-to-end CNN architectures based on AlexNet and Resnet32. The experimental results on the most representative public datasets have shown the usefulness of using palm vein synthetic images for transfer learning, outperforming the state-of-the-art results.

This paper constructs an alternative history of wood in Leuven (Belgium) to help contextualize the city's contemporary project for a building materials bank as part of their larger efforts to make the urban metabolism more circular. Focusing on the history of Leuven's forests, canal, and deconstruction practices, this paper aims to show how the materials bank will also intervene into the larger overlapping timber flows of the region. By analysing how (circular) wood flows were strongly intertwined with urban and landscape development projects in pre-industrial Leuven, the paper speculates on how the materials bank could revitalize broken spatial connections towards more circular timber flows in Leuven, while catalysing circular urban landscape and infrastructure development. It shifts focus from a materials bank as a circular waste management response "redirecting" wood waste flows to an integrated infrastructural question addressing path dependencies in the wood extraction, processing, consumption and disposal chain.
Existing research on outdoor thermal comfort in urban areas focuses on meteorological factors such as temperature, relative humidity, wind speed, and radiation on sunny or cloudy days. However, climate conditions befo...

This study determined the bending strength values of laminated veneer lumber (LVL) made with beech (Fagus orientalis L.) veneer obtained by the peeling process and having four different moisture content values (0%/oven dry, 12%, 18%, and 25%). Bending tests were carried out in two different ways, i.e., for the flatwise and edgewise aspects of the LVL. Strain maps were created using two-dimensional digital image correlation (2 D DIC) and the samples having different moisture contents were compared. At the same time, the amount of displacement of the samples during the bending test was determined via conventional and DIC methods. Results of the study determined that the moisture content was effective in bending strength and tension zones. It was observed that increasing moisture content created homogeneous distribution of deformation. It was also observed that the data obtained by the 2 D DIC method were compatible with those obtained by the conventional method.
