Abstract: Urban Heat Island (UHI) is the occurrence of higher temperatures in metropolitan areas with noticeable impact on human comfort. The objectives of the study were to (i) map and examine the Landuse Landcover (LULC) changes in Lafia, (ii) map, measure and examine the level of Normalize Differential Building Index (NDBI), (iii) assess the distribution changes in Land Surface Temperature (LST) and UHI, (iv) examine the impact of UHI in Lafia.

Abstract: This study aimed at evaluating the protective role of Jatropha tanjorensis on testicular architecture and reproductive hormone profile in Dichlorvos exposed Male Mice. Thirty sexually matured male mice with mean weight of 22.45± 3.05g were used in the study. The animals were selected randomly into six groups of five mice in each group. Group A was the control group, while group B was administered DDVP at 5mg/kg/bw/day. C, and D were administered 250mg/kg/bw/day of fresh and dried J. tanjorensis leaves respectively. E and F were coadministered......

Abstract: The rapid growth of industrialization and urbanization has led to an unprecedented rise in solid waste generation, posing significant environmental and energy challenges. Integrating circular economy (CE) principles into waste-to-energy (WTE) systems offers a sustainable pathway to address these issues by transforming waste streams into valuable energy resources while minimizing material loss. This paper explores the interconnection between CE and WTE approaches, emphasizing the transition from a traditional linear “take–make–dispose” model to a regenerative.......
