Abstract Adequate ecological information on forest status is essential for informed management decisions. This study assessed tree species diversity in Omo Biosphere Reserve and the International Institute of Tropical Agriculture (IITA) Forest in Ogun and Oyo States respectively. A systematic line transect method was used to establish twelve (12) sample plots (50 m × 50 […]
STRENGTH RESPONSE OF TEAK (Tectona grandis Linn. F.) GLUE-LAM BOARDS TO VARIATIONS IN ADHESIVE SPREAD RATE AND LAMINA DIMENSION
Abstract The over-exploitation of the forest has left the forest with small diameter logs. Apart from having small diameter, the trees are also characterized by juvenile wood with large proportion of sapwood, therefore, there is need for laminated board to meet the need of end users. This research assesses the effect of glue quantity and […]
THE EFFECTS OF UNREGULATED URBANIZATION ON THE WETLAND-RIPARIAN ECOSYSTEM OF YENAGOA METROPOLIS, BAYELSA STATE
Abstract This study examines the effects of unregulated urbanization on wetland-riparian ecosystem of Yenagoa metropolis, Urbanization in Africa started later than any other part of the globe and at an extraordinary rate of roughly 40%. Africa is the continent that is urbanizing the quickest in the globe right now. A mixed research design was adopted. […]
STIMULATORY EFFECTS OF CASSAVA EFFLUENT ON THE GROWTH RESPONSES OF Euglena viridis (O.F. Müller) Ehrenberg AND Chlorella vulgaris Beijerinck
Abstract This study evaluated the effects of cassava mill effluent (CME) on the growth of the microalgae Chlorella vulgaris and Euglena viridis. The microalgae were cultured in seven CME concentrations (0, 5, 10, 25, 50, 75, and 100%), each in triplicate, and monitored over 14 days. Growth was determined at two-day intervals using a 721 […]
A MULTI-LAYER BIOMIMETIC SOCIO-TECHNICAL ARCHITECTURE FOR PHOTOVOLTAIC AND AGRIVOLTAIC SYSTEMS: INTEGRATING COMPETENCE INFRASTRUCTURE AND COMMUNITY CO-DEVELOPMENT IN THE GLOBAL SOUTH
Abstract Photovoltaic (PV) and agrivoltaic systems are increasingly deployed to address energy access, land-use efficiency, and climate resilience challenges across Africa and the Global South. However, long-term system performance frequently remains constrained by workforce capability gaps, weak institutional integration, limited community participation, and fragmented socio-technical design approaches. This study proposes a multi-layer biomimetic socio-technical architecture […]
COMPETENCE INFRASTRUCTURE AND COMMUNITY CO-DEVELOPMENT AS AN INTEGRABLE ENGINEERING SUBSYSTEM: A BRIDGING CONSTRUCT FOR SOCIO-TECHNICAL RENEWABLE ENERGY SYSTEM ARCHITECTURES
Abstract Engineering system performance, particularly in decentralized renewable energy contexts, is increasingly shaped by factors that extend beyond technological configuration. Among these, competence has emerged as a critical determinant of system reliability, scalability, and long-term sustainability. Concurrently, growing evidence shows that community participation, local ownership structures, and decentralized governance mechanisms significantly influence infrastructure performance and […]
GROUNDWATER SAFETY, AESTHETIC QUALITY, AND PUBLIC HEALTH RISKS: AN INTEGRATED PHYSICOCHEMICAL AND MICROBIOLOGICAL ASSESSMENT OF BOREHOLE WATER IN BENIN CITY, EDO STATE, NIGERIA
Abstract In Benin City, Edo State, Nigeria groundwater supplies domestic water in many homes but the city’s urbanization and inadequate sanitation is a significant challenge to the quality of the groundwater and its public health safety. The study was used to determine the suitability of the groundwater from forty (40) privately owned boreholes for drinking […]
CHEMICAL COMPOSITION AND COMPARATIVE ANALYSIS OF THE WOOD OF TWO VARIETIES OF Bambusa vulgaris SCHRAD. EX J.C. WENDL
Abstract Determining the variation of chemical properties of the two varieties of Bambusa vulgaris is important to provide the information on the similarity and comparison of the chemical constituents for appropriate utilization. This study was therefore conducted to determine the chemical properties of the two available Bambusa vulgaris in Nigeria. Samples were collected from the […]
KNOWLEDGE SHARING PRACTICES AMONG ACADEMIC LIBRARIANS IN NIGERIAN UNIVERSITIES
Abstract This study investigated factors that influence academic librarians use of Web 2.0 technologies tools for knowledge-sharing practices in Nigerian universities. The study discussed demographics factors that influence the usage of Web 2.0 technologies, kinds of Web 2.0 technologies used by academic librarians, advantages of using Web 2.0 technologies and challenges that hinder the use […]
INFLUENCE OF SETTLEMENT PATTERN ON SOLID WASTE MANAGEMENT PRACTICES IN OVIA NORTH EAST LOCAL GOVERNMENT AREA, EDO STATE, NIGERIA
Abstract Settlement patterns play an important role in shaping municipal solid waste management practices, particularly in developing countries where waste management infrastructure is often inadequate. This study assessed the influence of settlement pattern on solid waste generation, storage, collection, transportation, disposal, waste separation, and recycling practices in selected urban (Okada), semi-urban (Usen), and rural (Iguomon) […]
