A Comparative Analysis of Heating Values of Saw Dust, Rice Husk and Coconut Shell in the Thermal Generation Of Electricity In Hadema Local Government, Nigeria

ABSTRACT Biomass is the major energy source in Nigeria contributing about 78% of Nigeria primary energy supply. In this work a comparative analysis of the heating values of saw dust, rice husks, and coconut shell in the thermal generation of electricity was carried out. In the study different masses of biomass were used and the corresponding electromotive force in millivolts obtained. A graph of e.m.f was plotted against mass of each biomass and a gradient was obtained. Bar graphs were plotte...

EXOSMOSIS AND ENDOSMOSIS VERIFIICATION USING WHITE RAW EGGS

ABSTRACT Exosmosis and endosmosis verification using white raw eggs have been carried out. Two beakers of dilute hydrochloric (HCl) acid solution were prepared. Two white eggs were placed differently into beakers labelled Beaker A and B respectively containing dilute hydrochloric (HCl) solution and left for five hours. Beaker A (containing Saltwater) was seen as more concentrated than the albumin in the egg. Water molecules moved from a low concentration point (albumin) to the high concentrat...

Structural and Optical Properties of ZnO Nano-Powder Synthesized by Combustion and Sol-gel Method

Abstract Nowadays, ZnO is considered as the most important chemical compounds due their distinctive properties owing to its wide band gab and large exciton binding energy. It is well known that the structural and the optical properties of ZnO differ by different methods of preparation. Therefore, in this work, ZnO power was prepared by two methods, namely sol-gel and combustion method with the aim of comparison. The obtained samples from both methods were investigated by many techniques for c...

Establishment of National Diagnostic Reference Level for bone Radiation Doses in Nuclear Medicine Department in Khartoum – Sudan

Abstract A diagnostic reference level (DRL) is an investigational level used to identify unusual high radiation doses in Nuclear Medicine procedures. DRLs are suggested action levels above which a facility should review its methods and determine if acceptable image quality can be achieved at lower doses. The high specific activity of 99mTc makes it suitable as a first pass agent, for multiple or sequential studies. Is preferred to 99mTc - pertechnetate. A certain amount of radiopharmaceutical...

The Steam Boiler

CHAPTER ONE THE STEAM BOILER 1.0 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...

Automation of Crime Record (A Case Study of Area D Division Ilorin)

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, search fo...

Physico-Chemical Investigation on Dumpsite Leachate in Ilorin Metropolis

CHAPTER ONE 1.0       INTRODUCTION 1.1       Background of the study The 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 presence of atmospheric water, high temperature and hi...

Design and Construction of a Variable Resistance Box

ABSTRACT In 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. TABLE OF CONTEN...

Effect of Variations in Meteorological Parameters on the Tropospheric Radio Refractivity Over Lapai, Niger State, Nigeria

ABSTRACT The 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 (N...

Iron Ore Mineral Deposits Exploration By Ground Magnetics In Kindani Area, Meru County, Kenya

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 data. A co...

Radioactivity Concentrations And Dose Assessment For Soil Samples From Wheat Plantation Areas Of Narok County, Kenya

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 concern on...

Characterization Of Snxsey / Sno2-Ni Prepared By Spray Pyrolysis For Photovoltaic Application

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 of tin sele...

Geophysical Prospection Of Iron-titanium Oxide (Ilmenite) Using Magnetic Method In Magaoni, Kwale County, Kenya.

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. Energy Dispersive X-R...

Investigations Into The Permeability And Tectonic Lineaments Of Homa Hills Geothermal Prospect, Using Ground Magnetic Method

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.
