  A Comprehensive Review on Microplastics Pollution in Nigerian Aquatic Environments

  Terngu Paul Ugosor, Asaasuen Terngu, Winifred Umbur Ukpoko, Naku Julius Uko, Raymond Lubem Tyohemba , Sesugh Ande

  Microplastics (MPs), defined as plastic particles smaller than 5 mm, have become persistent contaminants in aquatic environments worldwide. In Nigeria, growing evidence shows that these particles are widespread in rivers, lagoons, estuaries, sediments, and in food and drinking-water products…

  Isolation and Phylogenetic Diversity of Streptomyces from Underexplored Soils of Nepal

  Ram Prabodh Yadav, Praveen Kumar Singh

  The genus Streptomyces is a prolific source of bioactive secondary metabolites and remains central to antibiotic discovery; however, many ecologically diverse regions remain underexplored for Streptomyces diversity. In this study, soil samples collected from four ecologically distinct regions…

  Risk-based Project Scheduling Model of Large-scale Renewable Power Plant Constructions through Monte Carlo Simulation

  Noor Rabbani Talukder

  The construction projects of large-scale renewable power plants have a large schedule uncertainty due to environmental variability, regulatory approvals, and supply chain dependency. Conventional deterministic methods of scheduling, like the Critical Path Method (CPM), assume that activity times…

  Effect of Problem-Based Learning on the Academic Performance and Perceptions of TVET Students in Nomenclature of Inorganic Compounds

  Clinton Appiah Kodom

  Students in Technical and Vocational Education and Training (TVET) institutions in Ghana often struggle to master and apply IUPAC nomenclature for inorganic compounds, partly due to limitations of traditional lecture-based instruction. This study examined the effect of Problem-Based Learning (PBL)…

  An Exponential Ratio Type Estimator of Population Mean in Presence of Measurement Error and Non-response Error

  Namita Srivastava, Akrashi Bhardwaj

  In this paper, we proposed an exponential ratio type estimator for estimating the population mean in the presence of measurement error and non-response error. Also, assume that these two errors are present in both the study variable and the auxiliary variable. The theoretical expression of bias…

  An Efficient Estimator to Estimate the Population Mean for a Sensitive Variable Using Dual Auxiliary Information

  Manoj Kumar Srivastava, Namita Srivastava, Prem Veer Singh

  Randomized response technique (RRT) is designed to mitigate bias resulting from evasive responses in surveys. This article introduces a class of difference type RRT estimator for estimating finite population mean of a sensitive characteristic, leveraging information on auxiliary variables, as well…

  Characterization of Low-Cost Multi-Precursor Ceramic Membranes from Nigerian Agricultural and Biogenic Wastes for Synergistic Removal of Heavy Metals and Azo Dyes from Wastewater

  Chukwunonso N. Onyenanu, Joseph T. Nwabanne

  The contamination of water resources by heavy metals and recalcitrant azo dyes from textile and industrial effluents remains a critical environmental and public-health challenge, particularly in developing regions. Conventional ceramic membranes, while effective, are often prohibitively expensive…
