This study sought to explore a locally assembled 'Hom' point of use water treatment device by assessing aspects of its performance and possible effects of using it on compliant households and communities. The conceptual framework highlights poverty and environmental degradation as causes and consequences of one another, with ill-health caused by water-borne diseases reinforcing both to form a cycle. Whether or not the device would play a role in interrupting this cycle depends on its capabilities and acceptance, among other factors. Survey results indicated that the device is acceptable to 84% of respondents. Analysed data collected using questionnaires from 60 randomly sampled pilot device users revealed that it is useful to its users. Yield trials results led to the conclusion that one device unit could provide enough drinking water to satisfy the needs of a large representative household. Laboratory tests of water samples filtered with cartridges used for up to 10 years in the device found the water to be safe for drinking. It is concluded that the device is effective, environmentally friendly and useful to compliant households.

Background: Hot-melt Pressure-sensitive Adhesives (HMPSA) are eco-friendly pressuresensitive adhesives, with the potential of being used as substrates for transdermal patches. However, due to the low hydrophilicity of HMPSA, the application is limited in the field of Traditional Chinese Medicine (TCM) plasters.
Methods: Three modified HMPSA were prepared with acrylic resin EPO, acrylic resin RL100, and Polyvinylpyrrolidone (PVP) as the modifying materials.

Neglected tropical diseases (NTDs) affect over a billion people worldwide. The 2021-2030 NTD road map calls for innovative and highly efficient interventions to eliminate or significantly reduce the burden of NTDs. These include sensitive and cost-effective diagnostic techniques for disease surveillance.

Developing nations like Ethiopia face food and water shortages due to weather and droughts. The Bowa Dayole masonry gravity dam is expected to irrigate farmland downstream. Despite this, the engineering geology is complicated by the presence of highly fractured and weathered aphanitic basaltic rock, along with a weak unwelded to welded tuff rock mass in the dam foundation.

This study examines the viability of using graphitic-Carbon Nitride (g-CN) nanomaterial as shale stabilizer drilling fluid additive having applications in the oil and gas wells drilling. Shale stability is important especially when drilling horizontal and extended reach wells with water-based muds (WBM) to tap unconventional reservoirs namely shale oil and shale gas. For this study, the g-CN nanomaterial was produced by melamine pyrolysis, and characterized by X-Ray Diffraction, Scanning Electron Microscopy and Fourier Transform Infrared spectroscopy techniques.

This study determined the concentrations and seasonal variations of phthalate esters (PAEs) in water and sediment samples of the receiving stream within the vicinity of the Obafemi Awolowo University, Ile-Ife dumpsite. The objective of this study was to evaluate the pollution status of the study area by determining the levels of PAEs in water and sediment samples. This assessment aimed to understand the presence and extent of phthalate ester pollution in the study area.
