The rapid industrialization and urbanization of the Uruan Local Government Area of Akwa Ibom State, Nigeria, have significantly contributed to heavy metal contamination in the Nwaniba River. This research assesses the ecological risks associated with contamination using advanced machine learning techniques. Water, sediment, and marine organism samples were analyzed using ICP-OES to quantify seven heavy metals: iron (Fe), copper (Cu), nickel (Ni), lead (Pb), zinc (Zn), chromium (Cr), and manganese (Mn).

This study applied t-distribution statistical analysis to evaluate the quality of electrical cables produced in Lagos metropolitan city, Nigeria, with a focus on the standard conductor resistance and sample resistance. The aim of this work is to determine the conformity of thecables produced in Lagos to established standards and identify areas for improvement in the production process. The population mean and standard deviation of the sample data were estimated.

Her remarkable contributions to this domain have solidified her reputation as a pioneer in the field. Due to her extraordinary abilities and prowess, she is widely revered as the "Human Computer of the World" due to her extraordinary abilities.

In this paper, we examine shape optimization problems for thermoelasticity. We first propose a model of the thermoelasticity problem, and then provide a mathematical analysis for the model under consideration. We also show result for the existence of optimal shapes in three ways, and we conclude by giving a shape derivation result using the Lagrange method.

Gender equality implies that men and women have equal opportunities in education, career growth, financial independence and political empowerment. Guaranteeing rights of women and providing avenues is critical for attaining equity. Major problems faced by them are security, motherhood, family responsibility and self-imposed gender subordination. Women have fewer opportunities for economic participation than men, less access to basic and higher education, greater health and safety risks, less visibility at the higher positions and less political representation/leadership.

L’objectif de notre étude a été de mettre en relief l’efficacité du phénomène d’adsorption en utilisant comme matériau adsorbant l’argile pour éliminer les eaux contaminées par la Lévofloxacine. Des billes d’argile environ 0,3 cm de diamètres ont été fabriquées et activées thermiquement. Diverses matrices telles que l'eau ultra pure et l'eau de rivière contaminée par la Lévofloxacine à des concentrations différentes ont été prises en compte. Deux expériences ont été réalisées à savoir, l’adsorption par hydrolyse et l’adsorption par l’argile.

It Synthesis of 2-phenyl benzimidazole derivatives by oxidative condensation reaction with o-phenylenediamine (1.05 mmol), substituted benzaldehyde (1 mmol), catalyst cobalt (II) acetylacetoneand solvent CH3OH stirring at room temperature for 4 hours. Solubility experiments showed that the cobalt (II) acetylacetone is miscible with methanol and relatively readily soluble in polar solvents such as ethanol, and they are partially immiscible with no-polar solvents such as ethyl acetate, and tetrahydrofuran. The efficiency of the reaction was mainly affected by the amount of the catalyst.

Indian Knowledge System (IKS) is a vast body of knowledge deeply rooted in Indian culture, encompassing disciplines such as philosophy, spirituality, science and medicine. It is evidenced by its massive collection of intellectual texts, manuscripts and its well-documented heritage of texts, thinkers and philosophical schools in a wide range of subject areas. The IKS emphasize holistic well-being by using knowledge for self-purification, liberation and addressing contemporary challenges through ancient wisdom.

Higher education institutions continuously seek innovative approaches to track and assess alumni employability to improve academic programs and career support services. This study explores the use of predictive analytics in higher education, specifically employing the Autoregressive Integrated Moving Average (ARIMA) model to forecast alumni employability trends at Pamantasan ng Lungsod ng Pasig (PLP).

In [22], Kumar introduced the notion of b2-multiplicative metric space. Czerwik [2] generalized the concept of metric space and put the idea and terminology of b-metric space. In [15] B. Surender Reddy et al presented the concept of 2-multiplicative metric space. In this paper we introduce the concept of R-weakly commutative mappings on b2-multiplicative metric space. Also we prove a common coincidence point theorem for two pairs of R-weakly commutative mappings on b2-multiplicative metric space.
