    Abstract: Paper reports humidity sensing studies of V2O5-ZnO nanomaterial. When sample of V2O5-ZnO annealed at 500°C was exposed to increasing humidity, resistance decreased. Aging over six months was within ±6% for ZnO and ±2% for V2O5-ZnO; hysteresis was within ±6% for both ZnO and V2O5-ZnO sensing elements. Grain size for pure ZnO was 620 nm, and 400 nm f... Show More

    Abstract: Water samples were obtained from eight (8) different boreholes in Itu local government area, South-South of Nigeria. These samples were treated and analyzed using standard methods for their pH, temperature, turbidity, electrical conductivity (EC), total hardness (TH), dissolved oxygen (DO), biochemical oxygen demand (BOD), iron (Fe), zinc (Zn), cop...

    Abstract: The pH, conductivity and ions contents of aqueous extract of thermal insulation materials and deionized water were tested. Their corrosion behavior to A3 steel was investigated by static weight loss method. The results showed that the corrosion rate of glass wool was the lowest and performed local corrosion. The danger was the largest. Silica aerog... Show More

    Abstract: In the Anti-Atlas the lower Cambrian succession was traditionally considered as a post-rift series. Recently the Western Anti-Atlas appears to be affected by an early Cambrian rifting process. In the Igherm area (Western Anti-Atlas), this succession is represented by an alternating carbonate and siliciclastic facies reflecting several sedimentary e... Show More
