The Hemi-parasitic Mistletoe and It's Effects on Tree Population

A seminar research was conducted within Sokoto metropolis of Nigeria to identify the physiological and anatomical effects of mistletoe on the tree population, to which the research yield a tremendous result in which the mistletoe affect the tree to a level where the mistletoe brings about the total cell death (apoptosis) of various organs of the organism resulting in the organism total inactivity ie death

Phytochemical Screening and Proximate Analysis of Aloe Vera Growing on Highland and Lowland Areas of Sokoto Metropolis

ABSTRACT Phytochemical and Proximate analyses of two samples of Aloe vera from variable habitats (highland and lowland) of Sokoto metropolis were accessed. Phytochemical and proximate compositions of highland sample were 8.16mg/100g of Saponin, 3.40mg/100g of Glycoside, 1.80mg/100g of Alkaloid and 2.50mg/100g of Anthraquinone. Proximate constituents’ analysis revealed 6% of Moisture, 10.5% of Ash, 2.5% of Crude lipid, 8.13% of Crude protein, 1% of Crude fibre and 70.57% of Carbohydrate resp...

GEOLOGY OF KAFIN MAIYAKI AND ITS ENVIRONS, NORTHWESTERN NIGERIA

The study area Kafin Maiyaki and its environs is a segment of sheet 103 Federal Survey Topographical Sheet 103 Ikara NW. The area is underlain by migmatite-gneiss and medium to coarse grain gneiss and has been intruded by a series of Pan African Granitoids. Geological structures observed in the area were faults, joints and veins trending mostly in the NW-SE and NE-SW indicating the effect of Pan African Orogeny. No evidence of economic mineralization has been observed but from the petrographi...

Neuroprotective Effect of Croton Zambesicus Phenolic Extract on Synaptosomes of Rats Exposed to Environmental Toxicant

ABSTRACT Exposure to environmental toxicant was known to cause neuronal disorders in humans. Hence, the present study evaluates the toxic effect of leachate (an environmental toxicant) in the synaptosomes of female rats and the reversal effect of phenolic-rich fraction from Croton zambesicus. Fifty animals were divided into five groups. Group I (Control) received 0.5ml of distilled water only, Group II (non-withdrawal) received 0.5ml of leachate for 14 weeks, Group III (withdrawal) received 0...

SYNTHESIS, CHARACTERIZATION AND ANTIMICROBIAL EVALUATION OF CURCUMIN-BISMUTH NANOPARTICLES

Abstract Elemental bismuth has been reported to exhibit antimicrobial activity, but it does so only at relatively high millimolar concentrations due to its limited solubility in water. However, its solubility can be increased upon chelation with other materials like curcumin thereby increasing its potential as antimicrobial agent even at much more lower concentration. In this study, a novel Bismuth nanoparticless were prepared from non-toxic curcumin as stabilizing and capping agent to elim...

EFFECT OF TYPE OF CUTTINGS ON ROOTING OF ANACARDIUM

Vegetative propagation method through induction of adventitious rooting in both softwood and semi- hardwoodhypocotyl plus stem (HpS) and juvenile stem (JS) was reported in Anacardium occidentale, an average size tropical evergreen tree belonging to the Anacardiaceae family. The induction of adventitious roots is an essential process in vegetative propagation. Adventitious rooting in above cuttings was induced by exogenous application of root promoting substances (RPS) viz. Indole-3-butyri...

Taxonomic Composition, Abundance and Distribution of Phytoplankton in Ifewara Reservoir, Southwestern Nigeria

ABSTRACT The taxonomic composition, abundance and distribution of phytoplankton in Ifewara Reservoir, Southwestern Nigeria was studied for four months (February to December, 2015). Four sampling stations (designated Stations 1-4) were established along the horizontal axis of the reservoir from inflow region to the dam site end. The stations were all sampled at the marginal sides (A and C) and open water B except for Station 1 which was only at the open water. At each station, net plankton sam...

Geology and Water Quality Assessment of Okpoma Salt Lake Areas in Yala Local Government Area of Cross-River State, Nigeria

ABSTRACT Geology and Water Quality Assessment of the Salt Lake areas of Okpoma and its environs in Yala Local Government Area of Cross River State has been carried out. The study area lies between longitude 08o 361 E to 08o 411 E of the equator and latitude 06o 321 N to 06o 371 N of the meridian respectively. They belong to the Eze-Aku Group of the Late Cenomanian- Turonian age Southeastern Nigeria. Lithologically the area is underlain by shales and intercalation of sandstone. Igneous intrusi...

Tourism Database Management System Using Data Warehouse Approach

  ABSTRACT Tourism as being a great source of revenue in so many countries like Britain, Australia, Malaysia and many other countries. Seeing the viability of the sector in these countries where tourism as served as one of the life wire of the country economy, has stirred other country government to invest vastly in the sector. The tourism sector of the above named countries has served as a source of employment for the citizenry in various capacity. In reflection of the above statement, th...

EVALUATION OF INSTITUTIONAL REPOSITORIES IN AFRICA

This is an 86 page research project evaluating institutional repositories in Africa SCOPE OF THE STUDY This study focuses on Institutional Repositories in Africa in the three major directory of repositories. The webometrics ranking will be the main focus for this study with keyattention to repositories that have their contents in English Language. A brief review isgiven to OpenDoar and ROAR for comparison with webometrics ranking. Data to be used will be generated online and will be analy...

Petrophysical characterization of Reservoir Sands of Two Wells in the Offshore Depobelt of the Niger Delta Basin

Petrophysical well logs were integrated in an analysis for the reservoir characterization of C and D wells located in the Offshore Depobelt of the Niger Delta Basin, Nigeria. The study essentially determined reservoir properties such as Lithology, shale volume, Porosity, hydrocarbon saturation and Net-Gross from Well logs with a  view to determining the Reservoir quality. Two lithologies were identified using Gamma ray and Resistivity logs which were sand and shale but minor presence of carb...

Application of Shooting Method and Finite Difference Method in Providing Solution to Two Boundaries Value Problems

This paper investigates the efficacy of the shooting method and finite difference method in the numerical solution of two point boundary value non linear problems. The difficulty in providing exact solutions to two point boundary value problems via analytical methods necessitated the study. The shooting method which utilizes the Runge-Kutta method as integrator provides us with a better approximation to the solution than the finite difference method which utilizes second order, central differ...
