With looming global water-related issues, the monitoring of water quality for household and industrial consumption has become more pertinent. Rivers in nearby towns serve as primary water sources for Ekpoma town. 123 samples of stored river water were collected from 41 sampling locations and physical properties – pH, electrical conductivity (EC), s...

... the chemical elements described in this study have regulatory limits in the NSDWQ. The allowable limits provided in the regulatory standards were compared with the concentration values of the PTMs detected in this study ( Table 2). The potential toxicity of the metals, without a basis for comparison across all standards, was evaluated in depth using human health risk assessment. ...
Context 2
... the concentrations of metals in the stream sediments are indicative of pollution levels and how the source water contributes to the quality of the water being sold in towns. Figure 2(a)-2(h) presents a graphical and individual element outlook of the information presented in Table 2. Cu, Cr, and Al were not detected in the samples collected from Districts 2 and 3 (Figure 2(b), 2(f) and 2h). ...

Global Software Development (GSD) is a contemporary approach to software development that offers numerous advantages, including enhanced cost-effectiveness and timely delivery. It enables access to a vast pool of skilled developers and facilitates the exchange of best practices and innovative ideas within the software industry. However, effective project management plays a vital role in ensuring successful product development. Organizations that achieve project success consistently adhere to well-defined project management methodologies, resulting in desired outcomes within predefined time frames and allocated resources. The success rate of software projects significantly increases with diligent software management efforts. Nevertheless, the distributed nature of GSD presents significant challenges related to collaboration, information dissemination, and process control, which ultimately impede effective development and compromise software quality. In this study, we identify various challenges associated with the GSD process and propose strategies to overcome obstacles to effective project management. Additionally, we introduce a comprehensive framework designed to enhance managerial activities in GSD.
