CHAPTER ONETHE STEAM BOILER1.0 INTRODUCTION Boilers are pressure vessels designed to heat water or produce steam which can then be used to provide space heating and/ or service water heating to a building. In most commercial heating applications, the heating source in the boiler is a natural gas fired burner. Oil fired burners and electric resistance heaters can be used as well. Steam is preferred over hot water in some applications, including absorption cooling, kitchen, laundries, ste...
ABSTACT This Automation of crime record was developed for Recording crime for the police of Division D in Ilorin Kwara state. This system will help the Nigerian Police of providing information regarding criminals and the various activities they had carried out in the (recent) past, it also will go a long way in helping to checkmate crimes and criminals, this will also help in identifying new cases of crimes within a given locality. The application can record crime, report crime, s...

CHAPTER ONE1.0 INTRODUCTION1.1 Background of the studyThe municipal solid waste dumpsite (MSWD) examined is located at sawmill, okefomo and irewolede at yidi road street and within Ilorin Metropolis Kwara State. The dumpsites examined contain both biodegradable and non-biodegradable materials of all sorts. The different waste materials may contain different physical, chemical and biochemical properties. In the presen...
ABSTRACTIn this project a resistance box has been constructed using locally available materials namely, 1/3 and plywood for the construction of the box, cupper wire, Ferro board, soldering iron, soldering lead, screw and resistors. The resistance obtainable from the box ranges from 2-11W. The box is fitted with terminal s to allow easy use in physics laboratory practical. At the end of the experiment, the values obtained are very close to those obtainable using imported box. TA...

ABSTRACTThe aim of this work is to examine the variations in meteorological parameters (Temperature, Atmospheric pressure, and Relative humidity)on the surface radio refractivity, N, in Lapai town, Niger state of Nigeria, with focus on the wet and dry seasons. Lapai town, being the study area, is located within latitude 9º 02ʺ N and longitude 6º 34ʺ E along Suleja road, about 56 km east of Minna, Niger state capital. Meteorological data obtained from the Nigerian Meteorological Agency (NI...
Recent geophysical surveys have reported presence of iron ore deposits within Meru County. It has been speculated that there could be more deposits within the region. Ground magnetic surveying was used to detect magnetic rocks within host formations in Kindani area of Maua. A fluxgate magnetometer was used to measure the vertical component of the Earth’s magnetic field in some 98 stations, covering an area of about 25 km2. Diurnal and geomagnetic corrections were then done on the dat...
Naturally occurring radioactivity has existed in our environment since the creation of the earth. Uranium, thorium and potassium radionuclides are relatively abundant in rocks and soils. Poor agricultural practices such as excessive use of fertilizers also lead to accumulation of radioactive elements in the soil. Due to their radiation, these radionuclides pose exposure risks which could lead to health related problems like cancer to the people exposed. There is therefore a growing conc...
Nickel doped tin oxide and tin monoselenide thin films were coated using spray pyrolysis. Nickel doped tin oxide Precursor solution was prepared using a 0.05M Tin (II) Chloride (SnCl4.2H2O) and 0.05M Nickel chloride 6-hydrate (NiCl2.6H2O) in de-ionized water and then being added in ethanol in the ratio 1:1 to get equal proportions, followed by about 2-3 drops of hydrochloric acid. Doping tin oxide was done using uniform concentration of (NiCl2.6H2O) of 0-10 %. Precursor solution ...
The geology of Magaoni area is associated with the presence of heavy minerals. Magaoni neighbours Maumba and Nguluku where ilmenite was discovered by Tiomin Resource Inc. in1996, using drilling and chemical analysis. Ilmenite mineral is known to be magnetically weak, but provides observable magnetic response. In this study, ground magnetic survey method was carried out to map magnetic anomalies of established stations, associated with ilmenite bearing formations...
In this study, the tectonic lineaments and permeability around Homa Hills geothermal prospect, Nyanzian rift were investigated in order to explore its geothermal potential using ground magnetic method. A proton-precession magnetometer model G-856 of accuracy of ±0.1nT was used to take total magnetic field intensity of the earth at every station. A total of 86 magnetic stations were established over an area of about 76km2. The magnetic data at each station was corrected for both diurna...
Natural radioactivity levels and radiation risks due to construction sand mined from Tharaka region of Tharaka-Nithi County in Kenya has been measured. The region is mostly rocky with majority of rocks being volcanic rocks and sedimentary rocks of volcanic origin; the area is occupationally characterized by sand mining for construction purposes within the County and also in some parts of the neibouring Meru and Embu Counties. The sand is mined along the river banks and also gullies that...
Elastic electron-atom collision data from experimental and theoretical studies is useful in the interpretation of spectra obtained in X-ray photoelectron spectroscopy and Auger electron spectroscopy as well as in the Monte Carlo simulation of conduction electrons in solids. In principle the behaviour of an electron-atom collision system is predicted by solving the Schrödinger equation. However this task is far from simple in that the equation can only be solved exact...
