TIME SERIES ANA YSIS ON THE PRODUCTION OF CRUDE OIL IN NIGERIA (2011-2016)

The word is not interested in the storm you encountered but did you bring the ship in? It's is not the time a man spends in planning, it's the faith and confidence he put in his planning that really counts. Investigation has revealed that the economic base of Nigeria base on the crude oil. Hence there is every need to take a critical look into the production pattern of this product as to ascertain the trend direction to enable us understand the progressive or regressive direction of th...

TIME SERIES ANALYSIS ON MEASLES CASES IN NIGERIA

This research work describes a study that used measles disease data collected through Knoema health surveillance system to evaluate univariate time series method namely; autoregressive integrated moving average (ARIMA). The data obtained from 1980 to 2016 were used as modeling data and forecasting samples, respectively. The performances were evaluated based on three metrics: mean absolute error (MAE), mean absolute percentage error (MAPE), and mean square error (MSE). A low normalized BI...

TIME SERIES ANALYSIS OF NUMBER OF BABIES AT BIRTH IN FEDERAL CAPITAL TERRITORY, ABUJA (A Case Study of University of Abuja Teaching Hospital (UATH))

This research is about time series analysis and number of babies at birth in Abuja, between 2000-2017 using a monthly data. The box-Jenkin auto regressive integrated moving average (ARIMA) model was estimated and the best fitted model is ARIMA 1,1,1 with Bayesian information criteria (BIC) of 7.580, R2 of 0.402 and with P-values of the perimeters of the model less than 0. 05. The model was further validated with L-Jung Box text with residual been white noise. The mode was use to obtain ...

THE SOCIO-ECONOMIC AND ENVIRONMENTAL CHALLENGES OF THE EMERGING SLUMS SETTLEMENTS IN THE FEDERAL CAPITAL CITY, PHASE II ABUJA, NIGERIA.

The thesis examined the socio-economic and environmental challenges of the emerging slums settlements in the Federal Capital City, Phase II Abuj a (the study area). The study identified the failure of the authorities to provide adequate, safe and affordable housing and basic services for the teeming population of the study area as a fundamental factor responsible for the emergence and development of slums in the study area. The study assessed the socio-economic characteristics of resident...

THE ROLE OF LISTERIA MONOCYTOGENES AND OTHER BACTERIA IN MENINGITIS AND SPONTANEOUS ABORTION IN SOME TOWNS IN NORTHERN NIGERIA

The involvement of Listeria monocytogenes in bacterial meningitis and spontaneous abortion in some towns in northern Nigeria was investigated. Three hundred cerebrospinalfluid (CSF) samples, 300 blood and 300 placenta swab samples were collected from meningitis and spontaneous abortion patients in the study area of Bauchi, Jos and Kano. Three hundred nono (a fermented milk product) samples were also collected from milk hawkers at various locations in the study areas. The samples were in...

COMPARISON OF IMPUTATION METHODS FOR MISSING VALUES IN LONGITUDINAL DATA

ABSTRACTLongitudinal data are common in various sectors where repeated measurements on a dependent variable are collected for all subjects. Missing data pattern are caused when most planned measurements are unavailable for some subjects. The dropout process may cause three missing values mechanism, namely: Missing Completely at Random (MCAR), Missing at Random (MAR), and Missing Not at Random (MNAR). The missing values have influence on quantitative study that can be serious, leading to bias...

THE IMPACT OF MPAPE DUMPSITE SOLID WASTE LEACHATE ON SOIL QUALITY, ABUJA NIGEIUA

This study examined the impact of dumpsite on soil and plant quality in Mpape, Abuja FCT. The study employed both transect and quadrant techniques in collecting soil and plant samples. The soil samples were taken in both rainy and dry season for three months each at the depth of 0-30cm using soil auger. A total of forty-eight soil sample and thirty-two plant samples were collected, totalling eighty samples in and around Mpape Dumpsite and taken to Abuja Environmental Protection Board (A...

THE IMPACT OF INTERNET IN HEALTH CARE DELIVERY SYSTEM (A CASE STUDY OF GENERAL HOSPITAL KUBWA, ABUJA)

Advances in several key communication and information technologies are worth tracking for their impact on interactive health communication and ability to meet .customers' demands. One of these technologies is the inte1net. It is based on this that this research work is cal1'ied out to dete1mine the level at which the internet has been able to improve the delivery of healthcare services in the healthcare delivery system in Nigeria. An explanatory research methodology was adopted in the c...

Assessing The Impact of Urban Sprawl ON Agricultural Land Use And Food Security IN Shai Osudoku District

ABSTRACT Shai Osudoku, a District known as the cradle of Dangme land and Krobo culture, and a predominantly farming area, is experiencing the sprawl phenomenon. Agricultural lands, which serves as the main source of livelihood to majority of the inhabitants in the District, has been encroached by the process of urban sprawl. A major result of this phenomenon is a growing sprawl at the fringes of some of its major towns. This study focuses on assessing the impact of urban sprawl on agricultur...

THE EFFECT OF TEMPERATURE ON GLUTATHIONE PEROXIDASE FROM FISH

Glutathione Peroxidase (GPx) family of enzymes plays important roles in the protection of organisms from oxidative damage. GPx converts reduced glutathione (GSH) to oxidized glutathione (GSSG) while reducing lipid hydroperoxides to their corresponding alcohols or free hydrogen peroxide to water. This study was conducted to investigate the possible effects of temperature in vivo on Glutathione peroxidase (GPX) oxidative activity in fish tissues.An adult fully grown cat fish, (the African flath...

THE EFFECT OF HEAT ON SOME CHEMICAL PROPERTIES OF VEGETABLE OILS AND FATS

Human dietary intake comprises three macronutrients (protein, carbohydrate, and lipid) and a large number of micronutrients (vitamins, minerals, antioxidants, etc.). Good health rest, in part, on an adequate and balanced supply of these components to the human body [1 ]. Supplies and consumption of oils and fats are generally described in terms of seventeen commodity oils, four of 'which are of animal origin and the remainder of which are derived from plants. This description does not i...

Studies on The Use of Bioactive Materials in Molluscan Traps For The Control OF Schistosome Host Snails

Abstract As an aid to the control o f the schistosome host snails, effective bioactive materials namely cassava, cocoyam, and sweet potato (Domeh, 1998), sugarcane and peels, all in their raw and processed states were tested in simulated natural environment experiments. The experiments were conducted using ‘biopots’ traps designed using a pot with few small windows created on the sides to allow easy diffusion o f test materials to reach the water body to attract the snails It was observe...

Structural Integraton And Antiplasmodistal Activities of Some Compounds Isolated From THE Rhizome of COCHLOSPERMUM TINCTORIUM

ABSTRACT Cochlospernum tinctorium A. Rich was investigated for its chemical constituents and its antiplasmodial activities. The chemical constituents of petroleum ether, dichloromethane and ethyl acetate extracts of the rhizome of the plant were successively studied. The in vitro antiplasmodial activities for petroleum ether, dichloromethane, ethyl acetate, ethanol and water extracts as well as the isolated compounds were determined. Three compounds isolated from the dichloromethane extract ...

The Design And Evaluation of A Green House Type Solar Dryer And its Performance on Two Food Commodities; Cassava And Cocoa

ABSTRACT Drying, a process for food preservation involves subjecting a food commodity to high temperatures that aid in the removal of moisture thereby making the food shelf stable. The objective of this study was to design a greenhouse type solar dryer that would be used for the drying of cassava and other foods and evaluate the characteristics of the dried products. The rationale behind this study was that open sun drying has been the method of drying over the centuries but it is subjected ...

MODULATION OF EICOSANOEDS BIOSYNTHESES IN VIVO AS A MECHANISM-BASED EVALUATION OF PUTATIVE ANTI-INFLAMMATORY PLANT EXTRACTS

ABSTRACT The eicosanoids are a group of oxygenated unsaturated 20-carbon chemical compounds produced from arachidonic acid (AA), that mediate almost every step in the inflammatory process naturally. Some of the eicosanoids are anti-inflammatory while others are proinflammatory. Desmodium adscendens, a medicinal plant used by local herbalists to manage asthma, had been shown to be anti-anaphylactic in vivo, and to modulate AA metabolism in vitro. In this work, the anti-inflammatory properties...
