ABSTRACT Occurrence of overpressured formation is common in Tertiary basins (e.g. Niger Delta), which can result in geomechanical problems, such as “kicks”, loss of expensive drilling mud, blowout, stuck pipe, reservoir quality damage, wellbore instability etc. if it is not accurately predicted prior to drilling. This study did a critically re-evaluation of the two commonly utilized methods and practices involve in pore pressure work in the industry. The main aim was to accurately predict...
ABSTRACT Cenozoic sediments outcrop in the Niger Delta Basin. Deposits in the Basin thicken southward (down-dip) but thin northward (up-dip) around Bende – Umuahia area where approximately 260 m thick exposure was logged from base to top. Sieve analysis and petrography were carried out to establish the depositional settings of sediments while palynological analysis was undertaken in order to identify palynomorphs and establish their biozonations, determine and correlate age of sediments, as...
ABSTRACT A fully automated X/S band Mission Control Centre (MCC) for the Nigeriasat-2 (N2) and Nigeriasat X (NX) satellites was constructed in Abuja. The construction of the MCC consisted of the installation of the appropriate size of antenna and computer systems used for the control of the entire satellite mission. The MCC of N2/NX consists of three main segments: the ground station (GS) used for direct communication link with the satellite, the mission control suit (MCS) used for mission co...
Abstract A nanocrystalline and porous p-Polyaniline/n-WO3 dissimilar heterojunction at ambient temperature is reported. The high-quality and well-reproducible conjugated polymer composite films have been fabricated by oxidative polymerization of anilinium ion on predeposited WO3 thin film by chemical bath deposition (CBD). X-ray diffraction analysis of the deposited WO3 films revealed that as-deposited film was amorphous; however, an amorphous-to-crystalline phase transition was observed by r...
ABSTRACT The study was aimed at examining the spatial pattern of industrial production subcontracting in Onitsha Metropolis Anambra State Nigeria. Data were collected from documentary materials, questionnaire, in-depth interviews and field observation and were analysed using percentages, mean, standard deviation, nearest neighbour analysis and principal component analysis. The results of the study revealed that production subcontracting by firm size was more prominent in small and medium scal...
ABSTRACT This project is concerned with GSM subscription fraud detection system using artificial neural network technique. Fraud is a multi-billion problem around the globe with huge loss of revenue. Fraud can affect the credibility and performance of telecommunication companies. The most difficult problem that faces the industry is the fact that fraud is dynamic, which means that whenever fraudsters feel that they will be detected, they device other ways to circumvent security measures. In s...
Abstract The study was set out to investigate the prevalence of the five-child killer diseases and its cause effect on under-five mortality. It was driven by four major objectives; Determining the prevalence rate of the five child-killer diseases; Determining the proportion of mortality due to the five child-lciller diseases to the total under-five mortality in the studying area; Examining the correlation between the five child-killer diseases and under-five mortality and Determining the caus...
ABSTRACT This study was aimed at examining the food craving and aversion among first time pregnant women in selected health facilities in Enugu metropolis. The objectives of this study were to determine the type of food first time pregnant women crave for or have aversion to, identify their reasons for their specific food craving and aversion, determine the first time pregnant women’s awareness of the implication of food craving and aversion in pregnancy and to identify measures taken by fi...
ABSTRACT Four varieties of cassava, namely: 91/02324, 97/4779, 98/2101 and NR87184 were processed into chips (30 x 2.0 x3.0 mm), ‘abacha shreds (0.80, 1.0, 1.6 mm thick) ‘abacha’ slices (0.5 mm x 60 mm) and gari. Part of the chips was processed into ‘abacha’ slices and gari to compare the products with those made from fresh roots. The mechanical properties of the products, the hydration kinetics of the chips and the ‘abacha’ shreds as well as the chemical, functional, rheologica...
ABSTRACT In this study, two economic series which have changes in regimes were considered. Models considered for the two series are Simple Switching Mixture (SSM) model and Markov Switching Autoregressive (MS-AR) model. Predictions of future transition regime probabilities were performed using the Hamilton filter of m-period transition matrix for MS-AR model, while, the two state ergodic m-step ahead transitions probabilities for SSM model. Subsequently, forecast evaluation measures for the t...
ABSTRACT The aeromagnetic data of Chibok (sheet 134) and Damboa (sheet 112) areas, southern Chad basin were interpreted qualitatively and quantitatively. Spectral Analysis, Source Parameter Imaging (SPI), Standard Euler deconvolution, Forward and Inverse modelling methods were used in the quantitative interpretation with the aim of determining depth to the magnetic source bodies, magnetic susceptibilities and the possible mineralization in the area. Oasis Montaj 6.4.2, WinGlink 1.62.08, Surfe...
ABSTRACT Diabetes is one of the most prevalent chronic mellitus which occurs when blood glucose (sugar) increases more than normal. Diabetes management has been playing an important role on preventing or delaying occurrence of the life threatening diabetes complications. By providing a roaming operation environment, internet healthcare technologies can bring efficiencies and convenience to both diabetics and relative medics on diabetes management. The remote monitoring of patients is consider...
ABSTRACT The speed at which tourism industry growing in Uganda, East Africa and Africa as a whole has created need to extensively advertise to the rest of the world through internet based advertising. This project therefore was to develop a web solution for Abacus tours Uganda. Our study has established that unlike all other forms of advertising (Electronic and print media and word of mouth), the internet based advertising commands a wider coverage is more appealing to the user and is less ex...
ABSTRACT This research project was conducted to avail a centralized source of information concerning accommodation services provided by private hostels and other rental buildings for Kampala International University members. Current accommodations services provide by the university are limited. The research involved establishing the information one need to facilitate acquiring of these services by any individual of Kampala international University at any given time any where. This research ap...
ABSTRACT The work was carried out to determine the effectiveness of smoking and oven drying on the shelf stability and sensory characteristics of Atlantic mackerel fish fillets during storage. In the study, mackerel fish was eviscerated and cut into fillets, weighed and measured, cleaned and dipped in 75% saturated brine for 1 minute. It was smoked at a temperature of 60-70oC for 4hours. Products were then divided into four (4) batches after smoking and cooling. One batch was kept at room tem...
