Abstract: An assessment of the hydrogeochemical properties and irrigation water quality of groundwater in Rumuola, Rumuokwuta and Rumuigbo Communities in Rivers State, were conducted using conventional graphical methods and mathematical models. Plots of Piper trilinear diagram indicated that the groundwater in the area had [Na+ + K+] as the dominant cations while HCO3- and Cl- were the dominant anions; the water was further classified as 60% predominantly sodium chloride type and 33% as sodium bicarbonate type. Durov and Gibbs diagrams showed that the hydrogeochemistry of the water in the areas is characterized majorly by Ion Exchange, Reverse Ion Exchange, Simple Dissolution and Rock Weathering processes. Irrigation Indices using Sodium Absorption Ratio (SAR) and Residual Sodium Carbonate (RSC) revealed that the groundwater is excellent for irrigation purposes. Similarly, classifications based on the United States Salinity Laboratory (USSL) and Wilcox diagrams suggested that the water in the study area is of excellent quality for irrigation purposes.

Abstract: One potential source of wind energy that can be used to power highway lighting and telecommunication signalling is the turbulent airflow caused by vehicles moving along highways. To actualize this, a precise evaluation of wind speeds attributes is necessary in assessing the potential of wind energy. In this paper, we report on the wind potential alongEmbu-Nairobi highway at Juja by measuring the wind speed close to the highway. The wind speed data of the site at 1 m height was collected using Young wind sentry anemometer and vane, model 03002V and analysed on hourly time series data using Minitab Statistical Software. The Weibull distribution model gave a good fit for the recorded induced wind speed data. The model was then used to evaluate the Weibull distribution parameters, which were found to be k=3.0883 and c=4.689 m/s. The parameters were used to assess the wind power density along the highway, which was found to be 50.4 W/m2 where maximum extractable power is 29.8 W/m2.

Abstract: The potential of maize yield in sub-Saharan Africa (SSA) is rarely maximized due to adverse effect of Striga hermonthica. One of the largest challenge to food security is present by Striga species in the region affecting the livelihood of over 300 million people. Striga is the most devastating and widely spread parasitic weed species to maize production. Therefore, early maturing pro vitamin A (PVA) maize hybrids with resistance to Striga have the potential to combat this devastating effect. Two hundred and six early maturing PVA hybrids and four commercial checks were evaluated in Mokwa, Niger State of Nigeria for two years under artificial Striga infestation and in optimal growing conditions.......

Abstract: In the midst of increasing pressure of climate change and related effects on the urban ecosystem and human well-being, many countries have started following certain rules-regulations to control environmental degradation. India is also not an exception to that. But to transform the nature of looking at the urban development in India, there must be certain fundamental etiquettes and attitudes for environmental protection and preservation. We must nurture the value of protecting it our present generation for the benefit of future generation. This paper talks about the rapid urbanization and environmental challenges for cities in India. It discusses the important case studies of sustainable urban development around the world to fill the gap in the present effort.....

Abstract: Background:The aim of this study is to provide further insight into the impact of corporate social responsibility (CSR) on the resilience (OR) of the oil and gas industry in the Niger Delta region of Nigeria. In this study, CSR is investigated through the company's environmental and social programs, while OR is investigated by the continuous growth of the company's business in the community through long-term growth and financial volatility. Materials and Methods: The study was conducted using secondary datasets of crude oil spill incident from January 2011 to December 2012 in the Niger Delta. By adopting a quantitative research approach based on both positivist and relativist philosophy,......

Abstract: Artificial intelligence is currently being used for most purposes including managing climate change, improving health, cleaning homes and cities, creativity and innovation. In cities urban infrastructure has improved and smart technology is used to make them more livable without any problems. Efforts are made to upgrade systems so that lesser citizens live in poor socio-economic conditions of life. The problem of sustainability still remains. The aim of this paper is to analyze some important cities and view them in the light of sustainability and artificial intelligence- how......
