Determinants of Child Mortality and Morbidity in South Sudan.

ABSTRACT  The main objective of this study was to examine factors associated with childhood mortality and morbidity in South Sudan. The specific objectives were to establish childhood mortality, examine the effect of childhood factors on morbidity as well as examining the contribution of mother factors on childhood mortality and morbidity. The study used both descriptive and inferential analysis using secondary data from Second South Sudan household health survey (SSHHS2). Using univariate, ...

Four and Five Figures of Kifilideen (Power of Base 11) and Antikifilideen (Antipower of Base 11) Tables as a Tool For Mathematics Computation

The four-figure of power of base numbers of tables needs to be created for easy synchronization with the existing Logarithm table of power of base 10 which is working on four figures. Although the five-figure of power base numbers of tables are more accurate because it is having less approximation in its establishment. The four-figure table is easy to compute doing utilization because it is having less digits to work with. This paper presents the four and five figures of Kifilideen (Powe...

Health and Environmental Effects of Burning Plastic

Plastic is a material consisting of any of a wide range of synthetic or semi-synthetic organics that are malleable and can be molded into solid objects of diverse shapes. Plastics are typically organic polymers of high molecular mass, but they often contain other substances. They are usually synthetic, most commonly derived from petrochemicals, but many are partially natural (LPP, 2011). Plasticity is the general property of all materials that are able to irreversibly deform without breaking,...

Copper and Iron Distribution in Soil Profiles and Some Selected Vegetables of Saje and Sango Dump Sites

The current study was designed for determination of copper and iron and some physicochemical properties of soils collected from two selected dumpsites (Saje and Sango) in Ogun State, Nigeria by digging two depths of about 125cm. Samples were taken at different depth intervals of 25cm (i.e 0-25, 25-50, 50-75, 75-100 and 100-125cm). The soil were analyzed for physicochemical parameters such as Organic carbon, Organic matter, Soil pH, Electrical conductivity, Particle size, Cation Exhangeable Ca...

Use of Petri Net in Protocol Specification

Abstract  This project work is concerned with application of Petri Net in protocol specification. In this project work, definition of Petri Nets and Protocols are given. The role and importance of formal specification techniques are also discussed. Petri Nets are a graphical tool and could be used for the formal description of the flow of activities in complex systems like protocol. It is gaining popularity in recent years as a tool for the representation of complex logical interactions like...

Production and Quality Evaluation of Spoonable and Drinkable Yoghurt with Watermelon (Citrullus Lanatus) Juice and Pulp

ABSTRACT Yoghurt was produced and flavoured with graded levels of watermelon pulp and juice. Watermelon (Citrullus lanatus) juice and pulp was used to substitute 0, 10, 20, 30, 40 and 50% of yoghurt. The chemical, sensory and microbiological properties of the yoghurts were determined. The results showed that the pH of the yoghurt ranged from 4.68 to 4.90. The protein, ash, and fat content decreased with increase in watermelon juice and pulp. The fiber content increased with the watermelon pu...

Interpretation of High Resolution Aeromagnetic Data over Okigwe and some Adjoining Areas, South Eastern Nigeria.

ABSTRACT  Digitized high resolution total field aeromagnetic data over Okigwe and environ (Sheet 312) was interpreted using the standard 3-D Euler de-convolution and spectral analysis in order to determine depth to the magnetic basement, delineate the basement topography and relief, and delineate the trend of the structural features associated with the basin. The aeromagnetic data were subjected to various data enhancement and transformation routines using the Geosoft Oasis MontajTM software...

Convergence in Norm of Modified Krasnoselskii-Mann Iteration for Fixed Points of Asymptotically Demi Contractive Mappings

Abstract  This project report deals with the class of asymptotically demicontractive mappings in Hilbert spaces. We noted some historical aspects concerning the concept of asymptotically demicontractivity and studied a regularized variant of the Krasnoselskii-Mann iteration scheme, which ensured the strong convergence of the generated sequence towards the least norm element of the set of fixed points of asymptotically demicontractive mapping.

Intranet-Based Wiki with Instant Messaging Protocol

Abstract  This project developed an Intranet-Based Wiki with Instant Messaging Protocol (IBWIMP) for the Staff of the Department of Computer Science, University of Nigeria, Nsukka to enable them collaborate on tasks; like writing of documents like, memo, project guidelines, proposal/grants, and circulars with online security consideration. The essence of this work is to improve on the contributions staff make during work, in carrying out tasks with their colleagues irrespective of the person...

Fabrication and Characterization of Zeolites and its Application in Heavy Metal Capture

ABSTRACT Zeolite crystals were synthesized by mixing sodium silicate and sodium aluminate to obtain aluminosilicate gel which was further treated hydrothermally to obtain the final product. The zeolite crystals were characterized by x-ray diffraction (XRD) and scanning electron microscopy (SEM). The XRD result identified the synthesized crystals as zeolite z; additional evidence was provided by the SEM images which showed that the zeolite crystals were disc-shaped and the particle sizes rang...

Software Bugs: Detection, Analysis and Fixing

ABSTRACT  This research work is concerned with the detection, analysis and fixing of software bugs. The objective of this work was to identify software development process with a focus of identifying cost effective methods of developing and managing software systems by introducing a post-deployment debugging approach which helps track software’s stability and at same time serve as a software bug-data repository. To achieve this objective, a web-based application –BugTracker was developed...

Production and Evaluation of Extruded Snacks from Composite Flour of Bambara Groundnut (Voandzeia Subterranea (L) Thoaur ), Hungry Rice (Digitaria Exilis Staph.) and Carrot (Daucus Carota L.)

ABSTRACT Cleaned Bambara groundnut seeds were divided into four lots. Each lot was separately pretreated thus: germinated, roasted, germinated and roasted, and unprocessed which served as control. Each sample was ground, sieved, and extruded using single screw extruder. Consumer preference test was done by a taste panel of 50 people who rated the products on the attributes of colour, taste, flavour and overall acceptability using a 9-point hedonic scale. The treatment (roasting) given on the...

Effect of Co-Extruded Film on the Shelf Stability of Sliced Salted Pork Meat Product

ABSTRACT The study evaluated the efficiency of co-extruded polypropylene (PP) and low density polyethylene (LDPE) in extending the shelf-stability of unam inung traditional meat product during storage under ambient conditions. Fresh pork was processed, in traditional way, into unam inung meat product and stored for 6 months, under ambient room conditions as unpackaged, clay pot packaged (traditional method), and those packaged in polypropylene (PP), low density polyethylene (LDPE) and co-ext...
