Increase in number of cars without commensurate increase in the number of transport facilities and infrastructures has led to diverse traffic problems in many Nigerian cities like Akure.Factors which contribute to increase in the numbers of cars owned in Akure metropolis were investigated in this study.The study area was divided into three density
In this study, the PtCu bimetallic electrode is employed as the anode for the electrolysis of liquid ammonia.A simple co-doping approach is adopted to fabricate PtCu alloys with improved activity and 100% wool blanket top durability.The synthesized electrocatalysts are characterized by cyclic voltammetry (CV), x-ray diffraction (XRD), scanning elec
Low sound speed or low-density materials can be used as soft acoustic boundaries in water, potentially as low-frequency underwater sound insulation.This study uses a chiral structure to construct an acoustic metascreen with deep subwavelength thickness.The results show that the transmission coefficient of the metascreen decreases noticeably in the
It was determined that urgent in the 21st century the problem of food security remains quite due to the dynamic of global and trade-integration processes, causing contradictions and asymmetries of economic development.These processes are rather ambiguous because they exert varying effects on countries, depending on the level of their economic devel
