Abstract This study defines a new boundary between the crystalline and sedimentary rocks of Eastern Dahomey Basin at the southwestern part of Nigeria using a geophysical approach that combines regional aeromagnetic and ground resistivity read more data.Aeromagnetic data covering the entire Eastern Dahomey Basin were acquired at 500 m line spacing,
High growth in vehicle, contribute air pollution and reduce human health quality.One of pollutants that generated by motor vehicle read more emissions is carbon monoxide (CO).CO gas can cause health problems for humans, even if exposed to long periods time will cause death.Emission test devices have been widely available in many auto repair shops,
A three-phase foam is considered one of the promising advanced materials for fighting fires.However, the preparation conditions, cost and effect are key factors for industrial applications.In this study, new three-phase foam systems with fly ash and a complex surfactant are proposed.Five types of surfactants alcohol polyoxyethylene ether sodium sul
In this paper a robotic arm is modelled by a double pendulum excited in its base by a DC motor of limited power via crank mechanism and elastic connector.In the mathematical model, a chaotic motion was identified, for a wide range of parameters.Controlling of the chaotic behaviour of the system, were implemented using, two control techniques, la ra
