Trend of Neonatal Mortality in Nigeria from 1990 to 2017 using Time Series Analysis

The study examined the incidence of the rate of Neonatal Mortality in Nigeria. The incidence tested with use of Time Series Analysis (ARIMA). The trend plot of the incidence shows that there has been steady decrease in the incidence rate over the years. The series was stationarity using the Augmented Dickey-Fuller (ADF) Test, the result found to be stationary. The Correlogram of the incidence also supports the stationarity of the series at 1% level of significance. The model that best describ...

A TIME SERIES ANALYSIS OF DAILY EXCHANGE RATE OF U.S DOLLAR TO NAIRA FROM 2016-2017 (RECESSION PERIOD)

ABSTRACT This project presents an empirical study of time series modeling and forecasting of the official daily Exchange rate of Nigeria Naira for US Dollar in terms of buying rate, central rate and selling rate, from the period of 1st January 2016 to 19th of May 2017 (recession period). In this view, Box Jenkins approach was applied for the modelling of naira/dollar daily exchange rate using ARIMA model. The results of the analysis show that the series became stationary after fir...

Design and Implementation of an Offline Android-based English to Igbo and Yoruba Machine Translation System

                         ABSTRACTMachine Translation system is an automated system that translates text from a source language to target language. The source language is the main language upon which the target language is derived, while target language is the semantic equivalence of the source language. The source language and target language are described as the input and output to the MT system respectively. Machine translation is an area of applied research in human language p...

ISOLATION AND CHARACTERIZATION OF LUPEOL FROM THE METHANOL LEAF EXTRACT OF TAPINANTHUS DODONEIFOLIUS GROWING ON VITEX DONIANA

Tapinanthus dodoneifolius belongs to the family Loranthaceae and is widely distributed in West Africa, Europe and Asia, commonly known as mistletoe. It exhibits a wide array of pharmacological activities including antimalarial, anticonvulsant, anti- microbial, and is effective in the relief of menstrual and stomach pain. Lupeol, a pentacyclic triterpenoid was isolated for the first time from the methanol leaf extract of Tapinanthus dodoneifolius and characterized by spectral analysis. The...

Improvement of 2-Vessel Occlusion Cerebral Ischaemia/Reperfusion-Induced Corticostriatal Electrolyte and Redox Imbalance, Lactic Acidosis and Modified Acetylcholinesterase Activity by Kolavir

Abstract Disruption of electrolyte, redox and neurochemical homeostasis alongside cellular energy crisis is a hallmark of cerebral ischaemia and reperfusion injury.  This study investigated the effect of kolaviron (KV) on cortical and striatal cation imbalance, oxidative stress and neurochemical disturbances as well as neurobehavioural deficits in animals subjected to bilateral common carotid artery occlusion (BCCAO)-induced ischaemia/reperfusion injury. KV was administered at a dos...

A MULTI-WAVELENGTH VIEW OF M17 MASSIVE STAR-FORMING REGION

ABSTRACT In this project (A Multi-Wavelength View of M17 Massive Star-Forming Region), efforts were made to determine the distributions of polycyclic aromatic hydrocarbons (PAHs) within the M17 region. We find that PAHs are destroyed over a short distance or edge of the HII region. This PAH destruction edge can be located easily using Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSE) band-ratio images. We try to find out the relative roles of extreme ultraviolet...

Design and Implementation of a Digital Library system

ABSTRACTLibraries have been an important part of educational and information sector of any school.  The success of any library largely depends on proper management.Several libraries have suffered failure as a result of inadequate management and incapacitations in handling sensitive information as regards members of the library.  This research therefore, aimed at developing a digital library system, which will help direct and position library to meets its ever increasing demands.In the cour...

Phytochemical Analysis and Antimicrobial Effect of Calotropis procera (Sodom apple) Leaves Extract on Some Bacteria Isolated from Spoilt Nunu Milk.

ABSTRACTThis study was carried to with the aim of determining the antibacterial effect of Calotropis procera against some bacteria isolated spoilt nunu. Bacteria isolated from spoilt nunu were identified based on their Gram characteristics, morphology and biochemical characteristics. Calotropis procera was extracted using ethanol, methanol and distilled water. The ethanol and methanol extracts showed the presence of Saponins, Steroids, Terpenoids, Flavonoids, Tannins, Alkaloids, and Cardiac g...

Evaluation of room temperature Tribocorrosion behaviour of Al-4.5Cu/SiC Particulate Composite in Natural Sea Water

Room  temperature  tribocorrosion behaviour  of  Al-4.5%Cu/SiC particulate composite  was  evaluated against  stainless  steel  ball  in natural  sea  water.  Ab-initio,  the          Al-4.5%Cu  was  reinforced  with  5,10,15  and  20  %  SiC  reinforcements  to  produce  the Al-4.5%Cu/SiC  particulate  composite  by  st...

The main objectives of this project was to identify the rock types present at Ipole area using rock magnetic properties and to determine the presence of Diamondiferous Kimberlite in Ipole lithologies.The following methods were used to accomplish the task; Heavy Mineral Sampling in Streams sediments, Loam and Auger sampling, Airborne magnetic survey, Geographic Informatio...

Determinants of Information Security Awareness among Employees of Capital Market Registrars in Lagos, Nigeria: An Empirical Study

Abstract - The purpose of the study is to examine the determinants of information security awareness (ISA) among employees of Capital Market Registrars (CMRs) in Lagos, Nigeria based on established factors from the existing literatures on ISA. The main objectives of the study are; to determine the level of information security awareness among CMRs’ employees and to identify the components that influence information security awareness. This study utilised a survey design. Stratified ra...

Exploitation and Development of Non-metallic mineral deposits of Nigeria

In this academic term paper, the industrial minerals in Nigeria were evaluated. The economic potentials were determined. Also, the level of the development and the industrial uses of these minerals were evaluated. It will interest you to know that Nigeria has over 30 industrial minerals.

ESBL-producing Enterobacteriaceae

Background: Resistance to extended-spectrum cephalosporins among Enterobacteriaceae has been reported yetthey serve as the last line treatment for severe infections in Uganda and other countries. This resistance often leadsto nosocomial infection outbreaks and therapeutic failures from multidrug resistant bacteria. The main objective ofthis study was to determine the prevalence of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceaein clinical samples of patients in various wa...

SORPTION PROPERTIES OF HYDROLYZED STARCH GRAFT COPOLYMERS IN THE REMOVAL OF CADMIUM (II) AND COPPER (II) IONS FROM AQUEOUS MEDIA

Sorption properties of hydrolyzed starch graft poly (acrylic acid) andstarch graft poly(acrylonitrile) copolymers as sorbents for the removal ofCd (II) and Cu(II) ions from aqueous solution in batch process wereassessed.
