Socio-Economic Factors Associated with Urban-Rural Migration in Nigeria: A Case Study of Oyo State, Nigeria

Abstract: The study investigated socio-economic factors influencing movement of people from urban centres to rural areas in Nigeria with particular focus on Oyo State of Nigeria. Purposive sampling technique was used to sample 160 migrants in rural areas for the study. Data were collected from the respondents using interview schedule. The principal results of the study reveal that most of the respondents left the urban centres for the rural areas because of their inability to secure jobs in the towns transfer to rural areas in their places of work retirement and high cost of living in the urban centres. Also the principal results show that there is a positive and significant relationship between lengths of stay of migrants in the rural areas and their ages (r = 0.442 p = 0.01). There are significant differences in the lengths of stay on migration by the single married widowed and divorced migrants since the calculated F-ratio (3.04) exceeds the tabulated F-ratio (2.74). It is recommended that government should encourage the drift of people to rural areas by making available such amenities that would encourage the stay of the migrants. This encouragement would enhance rapid rural development and bring the rural communities to the mainstream of national development. (authors)

In vitro antiplasmodial activity and toxicity assessment of some plants from Nigerian ethnomedicine

Abstract: Context: The emergence and spread of Plasmodium falciparum-resistant parasites to nearly all available antimalarial drugs pose a threat to malaria control and necessitates the need to continue the search for new effective and affordable drugs. Ethnomedicine has been shown to be a potential source of antimalarial compounds or source of template for the synthesis of novel antimalarial molecules.Objective: The antiplasmodial activity and toxicity assessment of 30 plant extracts from eight medicinal plants identified in Nigerian ethnomedicine for the treatment of febrile illnesses were evaluated.Materials and methods: In vitro antimalarial activity was evaluated using Plasmodium falciparum NF54 (sensitive to all antimalarial drugs) and K1 (chloroquine/pyrimethamine resistant) strains in the [3H]-hypoxanthine incorporation assay. Toxicity was determined against mammalian L6 cells using Alamar blue assay.Results: The ethyl acetate extract of leaves of Ocimum gratissimum Linn. (Labiatae) and hexane extract of st...

Recent advances on the treatment technology of oil and gas produced water for sustainable energy industry-mechanistic aspects and process chemistry perspectives

Abstract: Produced water (PW) is the largest volume of wastewater generated during oil and gas recovery operations. It is a complex mixture of dissolved and particulate inorganic and organic matters ranging from near freshwater quality to concentrated saline brine. The management of PW has been the main focus of oil and gas industry in view of the stringent legislations on the discharge of oil and gas PW into the environment and the potential of PW as a source of fresh water, which hitherto comes from surface water, groundwater or municipal water, for water deficient oil producing countries. This article reviews current technologies for the management of oil and gas PW with a view of not only for more efficient removal and recovery of oils and other toxic agents, but also for environmental sustainability and fit-for-purpose reuse. The purpose of this article is to present some of the main technologies including primary treatment, secondary treatment including biological and membrane treatment and tertiary treatment especially advanced oxidation processes (AOPs) that have been used for the treatment of PW from oil and gas extraction; and to provide an overview of treatment technologies. The future developmental research needs for management of PW is also discussed.
