Hydraulic, textural and geochemical characteristics of the Ajali Formation, Anambra Basin, Nigeria: implication for groundwater quality
Abstract This study highlights the distribution ofhydraulic conductivity (K) in the regional aquiferous AjaliFormation of SE-Nigeria on one hand and assesses thepossible influences of textural and geochemical characteristicson the hydraulic conductivity on the other hand. Theinvestigation approach involved field sampling and collectionof 12 sandstone samples from different outcroplocations, followed by laboratory studies such as grain-sizeanalysis (GSA), constant head permeameter test and geo...
Assessment Of Forest Revenue System In Kogi State
ABSTRACTLow and arbitrary review of forest charges encourage waste and poor harvesting practices resulting in underdevelopment of forest resources. The study therefore assessed the type, value and changes in the value of forest charges in Kogi State between 1991 and 2009. Data on forest charges between 1991 when the state was created and 2009 were collected from the Forestry Service of Kogi State. GDP deflator was used to convert the forest charges in each year under study to real or constant...
Income Polarisation And Poverty Among Rural Households In Nigeria
ABSTRACTPoverty in Nigeria has been on the increase with consequence for Income Polarisation (IP). The IP which is the sum effect of alienation and identification between two groups at polar ends of the income distribution could worsen poverty. Studies on income distribution and poverty have mostly focused on income inequality to the total neglect of IP. Therefore, the extent and pattern of IP and its relationship with poverty among rural households in Nigeria were investigated.Data covering ...
Population pattern and phenological behaviours for selected medicinal plants in Nigeria; implications for ex-situ conservation
ABSTRACTRecent developments indicated increasing gene-pool depletion for most medicinal plants in Nigeria despite theirpharmaceuticals and therapeutic potentials. Initial socio-economic study involving three countries (Nigeria,Ghana and Republic of Benin) identified ten most frequently used medicinal plants. This list was superimposedon a vegetation map of Nigeria for the production of a distribution map ahead of an eco-geographic survey forpopulation and phenological studies. Sample sites we...
Metal Tetrafluoroborate Complexes Of Some Dicarboxyuc Acid Hydra2i Des
ABSTRACTEighty-eight divalent metal complexes derived from dihydrazides of oxalic, malonic, succinic, adipic, phthalic and :erephthalic acids, with manganese( 11), cobalt(ll), nickel(ll), copper(IJ), zinc(ll), cadmium(ll), mercury(ll) and magnesium tetrafluoroborates have been prepared. The effect of 1 :1 and 1:2 metal to ligand reactant ratios have been examined. The complexes have been characterized on the basis of their analytical data, magnetic susceptibility, electronic and IR spectral s...
The Significance Of Sacred Places In The Selected Indigenous Churches In Ekiti Land
ABSTRACTSacred places are non-homogenous sites where the mysteries of nature, the incorporealand supra sensible essence are encountered. Previous studies recognised the existence ofthese places in ancient Israel, and examined the socio-religious dimensions of the places,but they have not considered the recognition and patronage of similar places in indigenouschurches especially in Ekitiland, whose topography enhances the patronage of sacredplaces. This study, therefore, examined the functions...
Species Selectivity For Charcoal Production In Three Ecological Zones Of Nigeria
ABSTRACTSeveral factors influence the quantity of charcoal production in different parts of Nigeria. The study investigated species selectivity for charcoal production in three ecological zones of Nigeria. Data were obtained through the use of structured interview schedule administered to three hundred and twenty seven respondents selected through snowball. The data were subjected to descriptive and analysis of variance. The results show that the mean age of respondents was 44, male (88.1%), ...
A Correlation For Predicting The Viscosity Of Nigerian Crude Oils
AUST.RACTAn -elnpTricaZ'-eq"uarlon that could be used forpredicting the viscosity of Nigerian crudes ispresented in this paper.The correlation uses oil specific gravity as the maincorrelating parameter, and also incorporates theeffects of reservoir pressure, temperature and oilformation volume factor. 'i 'i _. .Dcua from well over 400 samples of Nigerian crudeswae used for developing the correlation, with mostsamples however, from reservoirs alar abovesaturation pressure. The results show how...
The Sequence Dependent Machine Set-Up Problem: A Brief Overview.
ABSTRACTThe Sequence Dependent Machine SetupProblem (MSP). a class of difficult problems incombinatorial optimization that is representative ofa large number of important scientific andengineering problems, has been attracting muchattention in recent times. In this study. literatureand historical reviews of the MSP were carriedout. Some recent developments were reviewedwhile possible future research directions werealso highlighted.
Hyperfictional Language In Michael Joyce’s Afternoon, A Story And Megan Heyward’s Of Day, Of Night
ABSTRACTThe hypertext, a relatively new digital genre, structures texts into links and nodes. Thisresults in textual plasticity which gives room for different forms of stylisticexperimentations by the authors of the texts. While scholars have focused on thestructural composition and general nature of hypertexts, they have not adequatelyattended to their distinctive features. This study addresses this neglect by examiningthe style of the language of hyperfiction.The study adopts Hallidayan mod...
Simulation Studies Of Nodular Iron’s Bull’s Eye Effect On Stress Concentration Under Plane Stress Conditons
AbstractA simulation study on the effect of the “bull’s eye” in ductile iron on stressconcentrations was done in this work. Using the model of graphite nodules in a cavity, atwo dimensional plate strip was subjected to plane stress conditions. The results werecompared to the traditional theory of modeling the graphite as holes (cavity) in the ironmatrix. In plane stress conditions, while the graphite in the hole model showed the holeas areas of stress concentration and therefore very cr...
Flooding and Welfare of Fishers' Households in Lagos State, Nigeria
ABSTRACT The study examined the effect of flooding on the fishing households' welfare in Lagos State. Data werecollected with the aid of structured questionnaire to elicit information from 412 fishers selected through a multistagerandom sampling technique. Data were analyzed using descriptive statistics, budgetary technique and inferentialstatistics. Results revealed that rainfall was the dominant climatic factor that had adverse effect on the fishingcommunities as 81.1% of the respondents ex...
Household Coping Strategies For Domestic Energy Price Changes In Northeastern
ABSTRACTIn Nigeria, high cost of Domestic Energy (DE) has put untold hardship on households. Copingstrategy is therefore imperative to meet household domestic cooking and heating needs. Investigatingevolving strategies would better inform DE experts and policy makers. This study was thereforedesigned to investigate strategies devised by households in Northeastern Nigeria for coping with theescalating prices of DE. The domestic energy types considered in the study include Liquefied NaturalGas ...
