ABSTRACT Soil samples were collected from cultivated farmlands, roadside topsoil, industrial sites, and local brass industrial site located in three major cities (Minna, Bida and Suleja) of Niger State. United States Environmental Protection Agency (USEPA) Method 3050 was followed to digest heavy metals from the samples, and subsequently, the concentrations of Cu, Zn, Pb and Ni were detem1ined using Atomic Absorption Spectrometry (AAS) technique. Generally, the mean concentrations .Vere 14±...
ABSTRACT This research focused on the assessment of the effects of different land on sites in Tunga Maje, Gwagwalada AreC7 Council of the Federal Territory, having the following objectives, and to examine soil physically of various land uses (three land uses C7na control) with a sample of depth; 0-15cm (topsoil) and _I 6-30crn (subsoil), to compare in soil properties between the three lands use.

ABSTRACT This study assessed changes in tree density and diversity on smallholder farms along Nigeria-Niger border. The study draws attention to the importance of the tree and the changes of tree grown on the smallholder farms in the border region. The study also assessed the knowledge of local farmers on tree changes and the method they use to tackle the changes in tree diversity. The study area is in the sand region which experiences little rainfall and a high temperature, therefore, droug...
Abstract The aim of the study is the assessment of rainfall and temperature variations in parts of Northern Nigeria. To achieve the aim, the study set out the following objectives (i) to determine variations in rainfall characteristics in terms of number of rain days, extreme rainfall amounts, variability and ranges; (ii) to determine variations in maximum, minimum and mean temperature patterns and using the time series to determine any trend in the change, (upward or downward) (iii) to pred...
ABSTRACT High Pressure (HP) mafic granulites (mafic garnet gneisses) in the Shai Hills suture zone occur as NE/SW trending isolated inselbergs in the Accra plains. They characterize the suture zone rocks of the Pan-African orogeny in Ghana. Various aspects of the Shai Hills suture rocks have been studied yet relatively little is known about its structural and deformational evolution. This work presents a new research into the structural, petrological and deformational evolution highlighting ...
ABSTRACT The Paleoproterozoic Birimian rocks within the Nsawam, Suhum and Koforidua enclave of the Suhum basin have been analyzed for their major and trace element concentrations and mineral chemistry. Twenty-nine (29) thin sections were prepared for petrographic studies. Twenty-five (29) samples were analysed for their major and trace elements contents and twenty-four (24) samples were analyzed for the mineral chemistry of selected phases. Based on the petrography, the geology of the area i...
ABSTRACT The general distribution, growth form and economic importance of Kha%a senega!sir (Bear) A. Juss. and Khaya ivorensis A. Chev. are described. Some aspects of the water relations of seedlings of these two species, the former a savanna species and the latter a forest species were studied with the view of ascertaining whether moisture plays an important role in determining the pattern of their distribution. &rowth of seedlings under four soil watering regimes namely - -0.3 (A), -0,4 (B...
ABSTRACT Background: Childhood undernutrition is prevalent worldwide especially in developing countries. It is associated with impaired physical growth and poor cognitive function among school children. Aim: To quantify the effect of consuming fortified groundnut based snack for four months on the nutritional status and academic performance of children (6-17years) enrolled on the GSFP in the Ashanti region. Design and methods: This was a quasi-experimental design that involved experimental ...
ABSTRACT Historically, the operations of Goldfields Ghana, Damang Mine had generated grade control models using smallest mining unit (SMU) of 2 m x 5 m x 3 m. Management has introduced the use of larger excavators example the Bucyrus RH 90C and RH120E O&K with bucket size 3.5 m hence, there is therefore the need to review the SMU being used for various pits for the Grade Control Modeling Procedures which will relate to the ability of the equipment to select ore or waste with minimal dilution...
Abstract The climate is warming, a trend that is projected to increase with increasing frequency and intensity of climate related hazards. Impacts are likely to be greater in developing countries because of dependence on climate sensitive livelihood activities. The nature and impacts of climate hazards require a study that goes beyond investigating a single hazard or livelihood activity to embrace multiple hazards and their impacts on the various livelihood activities. It is against this bac...
ABSTRACT Oyster mushrooms (Pleurotus species) have been an important food item in both developed and developing countries serving an invaluable resource for nutrition, health and disease prevention. Although several agricultural wastes lignocellulose have been used for cultivation of oyster mushrooms worldwide and in Ghana, the most utilized is the wawa (Triplochiton scleroxylon) sawdust and its amendments for the cultivation of Pleurotus ostreatus in Ghana. However, a longer period of 28 da...
ABSTRACT Financial models today rely on assumptions that make them insufficient in many real cases. The Geometric Brownian Motion model is assumed as a process for stock prices frequently. The study examined whether the behavior of weekly and monthly returns series of some selected equities listed on the Ghana Stock Exchange can be modeled with the Geometric Brownian Motion(GBM). The Augmented Dickey Fuller, Shapiro-Wilk, Ljung-box and some graphical methods are some statistical methods used...
ABSTRACT Geochemical mapping and multivariate factor analysis were performed on multi-element soil geochemical data from Bogosu area in southwestern part of Ghana. Multi-element soil geochemical data have been used in soil geochemistry for the characterization of underlying lithology as their surface expressions are often based on the elements’ spatial distribution (Grunsky and Smee, 2003). The objectives of the study were to determine the spatial distribution of the elements, determine el...
ABSTRACT Eukaryotic pathogens are responsible for several serious human diseases, however, most drugs used as treatment regimens are ineffective while others still in use are toxic. This study seeks to identify bioactive molecules from wood decay fungal (WDF) extracts with activity against eukaryotic pathogens (especially Candida albicans and Plasmodium falciparum). The Saccharomyces cerevisiae model organism for eukaryotic cell biology studies is extensively used to screen bioactive molecul...
ABSTRACT This is thesis was done based on the textural, mineralogical and mineral chemistry studies of arc rocks from the North Island of New Zealand. The rocks in the area are of two main groups: the Kiwitahi and Coromandel groups. Both the Coromandel group and Kiwitahi andesites are typically porphyritic with a phenocryst assemblage (20–60%) consisting of plagioclase + pyroxene + Fe –Ti-oxide in a granular groundmass rich in plagioclase laths and pyroxene microcrystals. The Kiwitahi sa...
