The study integrates electrical resistivity tomography (ERT) and vertical electrical sounding (VES) methods for investigation of the groundwater potential of the study area. Five ERT was conducted to determine the variation in resistivity of the shallow subsurface rocks both vertically and laterally in order to infer aquifer zones therefrom while twenty-four VES was carried out to compliment the information obtained from the ERT, determine vertical variation in resistivity, infer lateral variation in resistivity, identify depth to aquifer and infer groundwater prospect of the area. Three geoelectric layers were obtained with layer resistivity and thickness increasing northwards with shallower depth to aquifer obtained at Kutigi. K (ρ1<ρ2>ρ3) and Q (ρ1>ρ2>ρ3) resistivity type curves constitute 75% of obtained curves signifying increasing groundwater saturation and salinity, and are indication of increasing aquifer prospect with depth. The groundwater prospects in the area is generally high with properly constructed boreholes in these areas will produce prolific groundwater at 40 meters with higher yield expected at the southern regions of the study area around Enagi.

Despite barely being a novel concept, EVs have been rising in popularity because of the development of the technology and infrastructure required to support EVs on a large scale, a growing concern for the climate, and a fight to lower carbon emissions. Even though the demand for EVs rising every year, there have been a few major roadblocks that are affecting the growth and development of EVs in developing countries and households with lower incomes, specifically the high initial cost of building the infrastructure of EVs, EVs being more expensive than regular Internal Combustion Engine cars, and a skeptical consumer market. However, making conversions of ICEs into EVs or Plug-in Hybrid EVs (PHEVs) might circumvent many of these issues, including combating the problem of replacing every single ICE with a brand-new EV in the span of a few decades. This paper discusses the cost, efficiency, and public perception of converting ICEs to EVs and what a viable business model can look like while paying particular attention to customer needs and public perception.

Several factors contributed to the elevated levels of water pollution in the earth surface increasing the risk of wastewater pollution. Inorganic metal irons and suspended liquid metals are also leads cause of water pollution. Physical treatments for water treatment include the use of effective membrane filters in two ways. Small membrane filter and large membrane filters also used for commercial applications. Different types of nanoparticles are used for the treatment of organic contaminants suspended in the wastewater. The adsorption of a reactive dye through the hydroxyapatite (HAP) leads the excellent filtration of ions in the wastewater. Different types of photocatalytic reactors are used for the treating the large amount of wastewater in effective ways. These included the titanium based photocatalytic reactors that employed the sub-micron TiO2 particles from the treated water which accompany the treatment process. Polymer composites are used for removal of wastewater due to their low operating temperat Nanofiltration also used for removal of wastewater due to the formation of utilizing of the semipermeable membrane allows the fine removal of the different ions and different types of pollutants ure and susceptibility to environmental degradation as compared to other operations.
