This project work title “Regression Analysis on Inflation Rate in Nigeria” was carried out using Moving Average, Auto- correlation, and time series Models to obtain a fitted model for the Nigerian inflation data and to establish the formulated hypothesis. In this study the data was obtained from National Bureau of Statistics (NBS) Bauchi for the year 2005-2014. The method used is secondary data. The Moving Average, Auto-correlation and time series Models are used to analyze the data. Based on the analysis, it was discovered that Nigeria faced a Serious Inflation rate within 2011, 2013 and 2014. Similarly, it was found out that the two items tested indicated there is an Autocorrelation between them. It was recommended that Government should display a high sense of transparency in the fiscal operations to bring about realistic fiscal deficits. On the determining power of money supply on inflation, the policy of selective credit control should be pursued with the vigor it deserves. And Government should adopt and pursue with vigor policies such as encouragement of family planning to further reduced population growth rate.

A study was conducted in Ramat polytechnic to compare the effect of different types of waxing in prolonging the shelf life of a mango fruit harvested at harvest maturity. Wet and dry waxing were employed by using cassava starch as waxing material. It was observed that wet waxing has a significant effect in prolonging the shelf life of the fruit by minimizing the weight loss, delay in change of colour of the fruit and closely following by the drying waxing and the control responded poorly

Comparative analysis of the physio-chemical parameters of water stored in plastic and galvanized containers from borehole sources was carried out. A total of thirty (30) samples were randomly collected from boreholes sources and were subjected to physical and chemical laboratory tests using multi bench spectrophotometer model Hi 93712. The results showed that the highest values of Turbidity, TDS, pH, Colour which are 650 NTU, 9.6 Mg/L, 7.15 and 2.2 respectively, for water stored in galvanized containers drastically increases as compared to the values of the same physical parameters for water stored in the plastic containers, which may be attributed to metallic nature and sewage effluent of the containers. Also, the highest concentration of aluminium, cadmium, iron, copper, and hardness recorded are 0.2 Mg/L, 0.7 Mg/L, 0.8 Mg/L and 30.00Mg/L respectively. Although some of them are within the acceptable standard, others exceed the maximum permissible limit which poses serious health hazards. So, storing drinking water in plastic containers is better than in galvanized containers due to high risks of contamination.

The study evaluated the performance of an affordable irrigation system using locally made emitters. Three different plots were used, each plot comprises of three laterals, eighteen emitters and plastic reservoir. A Christiansen uniformity coefficient formula was used to evaluate the performance of the emitters. An encouraging result has yielded in comparison with ASAE standards widely accepted in global drip irrigation practice. Values of uniformity coefficient of 84.52%, 78.18%, 91.75 %, and with its corresponding average flow rate of 0.0062, 0.0055 and 0.0097L/min. respectively were recorded from the three plots. Both the Christiansen Uniformity coefficient and the Application rate fall within the acceptable limits for micro irrigation system design as compared to ASAE standards.

This research paper compares M/M/1 and M/M/N Markovian queuing models to determine a more suitable one for the enhancement of the system’s performance. Data traffic was collected from the wireless MikroTik router at the Senate Building of Ahmadu Bello University Main Campus using “Winbox” software monitoring tool for a period of 11 months from 31th January 2011 to 30th December 2012. The computation of this collected data gave the average arrival rate of 176.5 kilobits per second, the average service rate of 746 kilobits per second. By using these values in the analyses, M/M/1 was found to be better than M/M/3 because of lesser (86%) number of entities in the system and lesser number of entities (91%) in the queue waiting for service, as well as faster (5%) response time and lesser (20%) waiting time.

To determine the level of water deficit favoring the attack of pests (Red banded thrips) in cashew seedlings foliages, cashew seeds were germinated and raised to saplings (50-60cm) in polythene bags in a nursery. Sixteen vigorous seedlings were selected and transferred to a screen house and formed into four treatments as follows. Control (A) mild water deficit, (B) severe water deficit, (C) more severe water deficit (D) using densitometers to record the water deficit levels of each group. These seedlings were subjected to water deficit levels of 60 centibars (cb) 70 centibars (cb), and 80 centibars (cb), respectively by the trial and error method. Plants heights (cm), number of leave and transpiration rates of each group were assessed in six weeks and 2 experiments to determine the choice of the red banded thrips on the leaves from these treatment groups were carried out using 4 leaves decapitated at random from each treatment and exposing them to these insects in enclosed clear plastic boxes. Plant height, number of leaves, water loss (transpiration) were shown to be significantly different between the treatments were observed. The results of the experiment conducted have shown that the insect clearly choose leaves from control and mild water deficit more than they did severe and more severe water deficited leaves.

In this work, a mathematical model of Typhoid Fever was developed incorporating the effect of carriers on the spread. The population was divided into four compartments namely Susceptible, Infected, Carrier, and Recovered compartments. The stability analysis of the disease-free equilibrium and the Endemic Equilibrium states were carried out. The stability of the Endemic Equilibrium state implies that for as long as carriers exist in a population, Typhoid fever cannot be completely eradicated.

Housing affordability has been widely recognized as an essential issue in creating sustainable built environment especially in the context of developing world cities. This paper discusses strategy of sustainable development and urban transformation as panacea to affordable housing and its impact in attaining the goals of sustainability in Nigeria. It also discusses the growing problems of housing affordability in cities of developing world, using Benin City in Nigeria as a case study with a view to ascertaining the extent of the problem as well as the challenges it poses to creating sustainable built environment. The data utilized in the paper was generated through systematic survey of 100 households in the five Local Government areas into which the city was stratified. Findings of the study revealed the problems associated with obtaining sustainable urban housing in the city of which affordability is a major one. The findings also revealed that sustainable development and urban transformation are key issues that must be taken into consideration as panacea to the constraints of affordable housing in the city. Thus, it was suggested that the institutional framework to promote, enhance and encourage affordable housing provision should be created in the city.

The paper gives comprehensive study of the variation pattern of refractivity on earth surface with the three major metrological parameters (temperature, pressure and humidity). The measured data were collected at interval of 30minutes for the whole day. Different regression equations were used to analyse the data to predict the refractivity in a day over an eight-months period in Jos, capital of Plateau state, Nigeria. The measured refractivity was compared with predicted refractivity determined from measured temperature, pressure and relative humidity at 100m height. Correlation analyses were used base on the predicted regression equations for eight months, represents early dry season, late dry season, early rainy season and late rainy season. The study shows that refractivity increases with pressure and relative humidity while decreasing with temperature. The best predicted regression equation of refractivity with pressure, temperature and relative humidity is polynomial equation. The correlation of pressure, temperature and relative humidity ranges from 0.2067-0.7291, 0.2242-0.9061 and 0.6741-0.9686. The correlations in early rainy and dry seasons for humidity and temperature and late rainy for pressure have highest value, while regression equations for humidity and temperature have better performance and worst for pressure.
