Abstract: The study area defined by the coordinates (90°E − 92°E, 23°N − 25°N) is a significant region in Bangladesh, where accurate rainfall predictions are crucial for both the local population and policymakers. Understanding rainfall patterns in this area is vital for effective planning and resource management. Data on atmospheric variables, including temperature, rainfall, humidity, sea level pressure, and wind speed were collected from the Bangladesh Meteorological Department for various locations across the study grids for the period of 1964 to 2015. The descriptive statistics revealed that the pattern of the data of climate parameters is not normal. This dataset serves as the foundation for analyzing climate parameters and forecasting rainfall levels within the specified regions of Bangladesh. This study evaluates machine learning techniques, focusing on artificial neural networks (ANN) and classification and regression trees, C5.0, Random Forest, and Gradient Boosting as alternatives to traditional statistical models for predicting atmospheric phenomena. It reveals that conventional models often rely on assumptions unsuitable for chaotic systems like the atmosphere. Among the assessed models ANN, CART, C5.0, Random Forest (RF), and Gradient Boosting Machines (GBM) the ANN demonstrated the highest predictive capabilities for rainfall forecasting in Bangladesh, achieving superior training accuracy and Kappa values while also being recognized as the best overall performer based on ranking metrics.

Abstract: The study examined the relationship between creating fake identities on Facebook and the pursuit of pleasurable experiences. A total of 603 participants, consisting of 252 males and 351 females, were surveyed to gather insights. The results, analyzed using an independent samples t-test, indicated a significant difference in the number of fake identities created by each gender. Females reported a higher average number of fictitious identities as a means of seeking pleasure. Additionally, correlation analysis revealed a weak relationship between the creation of fake identities and the desire for pleasurable experiences, with a Pearson correlation coefficient of 0.127. These findings suggested that although the pursuit of pleasure may influence the creation of counterfeit identities, it is not the primary motivation. The results also indicate that females tend to be more active than males in generating these false personas on the Facebook. The research highlighted notable gender differences in social media behavior and provided insights into the underlying motivations for users crafting fake identities on Facebook. This understanding could have implications for grasping user dynamics on social media and the psychological factors that drive engagement with digital identities. Future research could expand on these findings to explore the long-term impacts of such behaviors on individuals' online experiences and interactions.

Abstract: The slaughter of pregnant animals for meat has been reported in different parts of the world. This practice is becoming a very serious constraint to future livestock populations. Information on the level of fetal wastage in slaughtered cattle in Ethiopia is limited. The study was aimed at evaluation of the incidence of fetal wastage of pregnant cows slaughtered at Gambella Municipality Abattoir, Ethiopia. An active abattoir survey study design was employed. The data on breed, origin and number of the cattle slaughtered at the abattoir were used. The data were analyzed using SPSS software. The results showed that there was significant (P<0.05) higher proportion (70.5%) of the slaughtered cattle of Nuer (Abigar) breeds followed by Horro (16.6%). There was significant difference (P<0.05) in the rate of fetal wastage among the studied months with the highest value (46.67%) observed in November. There was significant difference (P<0.05) in the pregnancy status among the studied trimesters with majority of the fetuses (42.86%) encountered throughout the period under study were in the second trimester. During the study period the fetal wastages for pregnant cows accounts for economic losses of 828,000.00 ETB (25,668.00 USD). There should be legislative reinforcement through sound surveillance in the ruminant production and an integrated strategic planning and decision-making on animal food security in Ethiopia.
