Proximate Determinants: The Pathways Of Influence Of Underlying Factors On Under-Five Mortality In Nigeria

   Abstract Nigeria is a country with one of the world’s highest rate of under-five mortality. Any innovative research aimed at bringing solutions to this problem should be considered worthwhile. This study examined how socio-economic, demographic and cultural factors (called underlying factors), influence under-five mortality in Nigeria by identifying some other direct factors (called proximate determinants) through which the underlying factors influence under-five mortality. It used d...

A Refinement-Based Heuristic Method For Decision Making In The Context Of Ayo Game

   ABSTRACT Games of strategy, such as chess have served as a convenient test of skills at devising efficient search algorithms, formalizing knowledge, and bringing the power of computation to bear on “intractable” problems. Generally, minimax search has been the fundamental concept of obtaining solution to game problems. However, there are a number of limitations associated with using minimax search in order to offer solution to Ayo game. Among these limitations are: (i.) improper de...

Effects Of Boiling On The Proximate Analysis And Mineral Composition Of Three Species Of Garden Egg (Solanum Ailhiopicum, Solanum Aubergine And Solanum Anguivi)

ABSTRACT Three species of garden egg namely Solanum aithiopicum, Solanum aubergine and Solanum anguivi processed into raw and boiled powdered flour, samples were taken for their nutritional and mineral components using standard analytical methods. Proximate composition determined include total ash, moisture content, crude fibre, crude protein, crude fat and carbohydrate by difference, the mineral components determined are P, Fe, Mg, Na, Mn, Zn, Ni and Cu. The proximate analysis (%) shows th...

Production Of Alpha Amylase Using Fungus From.The Rhizosphere Of Moringa Oleif'era .

ABSTRACT Alpha amylase enzyme (EC 3.2..1. 1) (a-1, 4 glucan-glucanohydrolase) is widely distributed in nature such as plants, animals and microorganisms. Production of extracellu Jar alpha-amylase from fungi was isolated from rhizosphere of Moringa oleifera. Three (3) fungi isolates were selected after serial dilution of the soil samples, four optimization parameters was employed to determine the enzyme activity and they include effect of inoculum size, pH, nitrogen source and surfactant·on...

Determinants Of Ante-Natal I-Iealti-1 Care Utilization Among Women In Nigeria.

ABSTRACT Problems of pregnancy and birth delivery cause more deaths and disability than any other reproductive health problem. The situation is worse in developing countries like Nigeria due to inadequate access to antenatal care services and lack of utilization. A pregnancy not long after the previous childbirth may result in poor health outcomes for the mother, poor health status for the child and a reduction in probability of survival for both mother and child. There are past studies on m...

Antibacterial Effect Of Zingiber Officinale On Staphylococcus Aureus

.ABSTRACT The growing population concern about health has recently led to the development of natural antimicrobials to control diseases. Medicinal plants and spices are one of the most commonly used natural antimicrobial agents in food and have been used traditionally for thousands of years by many cultures for controlling common health. Zingiber ojjicinale has long been used as naturopathy due to their potential antimicrobial activity against different microbial pathogens. This study was co...

Knowledge And Determinants Of Contraceptive Use Among Women Of Reproductive Age In Nigeria

Abstract Lack of contraceptives use is major concerns not only in Sub-Saharan Africa but also in many other developing countries in the world especially in Nigeria. Therefore, this study assess the factors that determines contraceptive useamong couples in Nigeria, Data were obtained from 2013 NDHS, and weighted sample of 38,676. Univariate result showed that the socio demographic factor is significant with the contraceptive use. The bivariate analysis revealed that there is a significant ass...

Prey Alence Of Dengue Virus In Mosquitoes Caught In Oye Ekiti, Ekiti State, Nigeria

ABSTRACT Dengue Virus is the most prevalent arthropods borne viral infection in tropical and sub-tropical regions worldwide and they are transmitted by Aedes aegypti and Aedes albopictus. This experiment was conducted with the aim of detecting and establishing possible sylvatic transmission of Dengue Virus in mosquitoes caught in Oye Ekiti. Mosquito life traps were used to trap 200 Aedes mosquitoes which were then knocked down by the use of insecticides. RNA were extracted from the mosquitoe...

Enhancing Compression Ratio Of Variable-Byte Scheme For Inverted File Index

ABSTRACT: One of the most important characteristics of file compression is to preserve memory with all its temporary and permanent images, in addition to maintaining the speed of performance in the process of compression and decompression and increase the frequency range in the transmission and reception from long distances. The examined the performance of Variable-Byte compression scheme over sequences of integers. Variable-Byte algorithm which has high compression speed and decompressio...

Discontinuous Dynamical Systems And Stabilization.

Abstract In this research we consider discontinuous dynamical systems. We discuss the uniqueness of solutions and the stability analysis. We also report a number of sufficient conditions for uniqueness. We also present specific results to piecewise continuous vector fields and differential inclusions, with some examples and applications

Prevalence Rate Of Intestinal Parasites Among Schools Children In Al-Kalakla Locality- Khartoum State.

Abstract This study was conducted on schools children in Al-kalakla locality in Khartoum state. In this study, 134 stool samples were collected from students (67 males and 67 females). The stool samples were processed by wet preparation technique, formal ether concentration technique and saturated sugar floatation technique. The results revealed that out of the 134 stool samples collected from schools children in Al-kalakla locality in Khartoum state, 48 were found positive for gastrointesti...

Geo-Electric Soundings For Groundwater Exploration In Part Of Port Harcourt, Rivers State, South-Eastern Nigeria

ABSTRACT Groundwater is the water that exists in pore spaces and fractures in rocks and sediments beneath the water table. The need for groundwater has increased tremendously due to the unavailability and the contamination of surface water bodies by the intrusion of saline water and human activities. · The geo-electric soundings were carried out in Eleme Port Harcourt, capital of Rivers state in order to delineate the subsurface geo-electric layers and the depth to the aquifer unit for grou...
