Influence of Hydrologic & Sediment Parameters in Modeling Stream Flow of Osun River, Osun State Nigeria

CHAPTER ONE        INTRODUCTION1.1     Background to the studyThe water is the most important natural resource especially in the arid or semi-arid zones that face high population growth, scarcity of freshwater, irregularity of rain- fall, excessive land use change and increasing vulnerability to risks such of drought, desertification and pollution. Thus, the availability and the sustainable use of this resource become the core of t...

Design and Construction of a Remote Controlled Tri–Band Frequency Jammer.

CHAPTER ONEINTRODUCTION1.1       BACKGROUND OF THE STUDYA mobile phone jammer or signal blocker is an instrument used to prevent cellular phones from receiving signals from base stations. The process of blocking the receiver to receive a transmitted signal is called Jamming of the signal. The jammer effectively disallows cellular phone signal when activated. These devices can be used in practically any location, but are found primarily in places where a pho...

The Effects of Sugar Cane Bagasse Ash as Supplementary Cementitious Material in Production of Concrete

ABSTRACTSugarcane Bagasse is the fibrous residue leftover when sugarcane is squeezed for its juice. Bagasse ash is obtained by subjecting Bagasse to calcinations using furnace. This work is aimed tat using Bagasse Ash as a replacement in the production of concrete.The bagasse was collected from dumped in a market in Kano and thereafter sun-drie to eliminate any trace of moisture. It was then taken to the blast furnace for calcinations(controlled burning) at a temperature of 1250OC for ...

Operation and Maintenance of Steam Boiler

ABSTRACTThe steam boiler is to control specification problem, to illustrate how the evolving algebra approach to the specification and the verification of complex system can be exploited for a reliable and well-documented development of executable but formally inspectable and systematically modifiable code. A hierarch of stepwise defined abstract machine model in developed, the ground version of which can be checked for whether it faithfully reflects the informally given problem. The se...

Investigation of the Spatial and Temporal Variation of Sediment Yield and Surface Runoff in Offa Watershed Kwara State

ABSTRACTIn this research, an hydrological modelling tool, soil and water assessment tool (SWAT) used to investigate the spatial and temporal variation of sediment yield in a watershed. The model was run for 31years using spatial data such as Digital Elevation Model, soil map, land use and precipitation, wind and solar radiation. The results showed that the maximum value of surface Runoff was estimated as 19100.034mm in the year 2005 while the minimum surface Runoff was 1000.671mm in th...

Design, Fabrication and Performance Evaluation of Pedal Operated Groundnut Decorticator

ABSTRACTShelling of groundnut pods (Arachis hypegea) by hand is tedious, laborious and unhygienic with low efficiencies. As a result farmer get low income due to amount of broken kernels and a lot of time is lost in the tedious shelling operation. To overcome this problem, pertinent parameters that influence shelling efficiency of pedal operated groundnut decorticator were identified. Pedal operated decorticator were designed and fabricated with chain and sprocket of bicycle and aluminu...

Real Time School Bus Tracking System Using (Rfid)

ABSTRACTIn present time due to increase in number of kidnapping and road accident cases, parent always worry about their children.This paper proposes a SMS based solution to aid parent to track their children location in real time. The proposed system takes the advantage of the location services provided by module kit which carry by the child in their school bag. It allows parent to get their child location on a real time map by the geographical co-ordinates which send by module kit. I...

Investigation on the Characteristics of Cornstalk Ash Blended Cement

ABSTRACTAnalysis of investigation on the characteristics of cornstalk blended ash cement was carried out based on the interest of coming out with a good pozzolanic material with all required cement properties. Hence, the supposed competitive demand relationship between cement products in construction works has been majorly wined by cement and this makes people to depend mostly on it despite the increase in price and some with inadequate properties.      &nb...

Estimating Some Mechanical Properties of Rock From In-Situ Rebound Values (A Case Study of Oreke Open Pit Quarry)

ABSTRACTThe research deals with estimating some mechanical properties of rock from in-situ rebound value in Oreke open pit quarry ,N-Type  Schmidt rebound hammer data were collected from Oreke open pit .the data were collected with the view to ascertain the suitability of Schmidt hammer for quick ,cheap and less cumber some estimation of the uniaxial compressive strength of marble .The data collection was strictly carried out by ASTM and suggested equation by different authors.

Design and Construction of Automatic Change-Over for Three Phases

ABSTRACT         The main aim of any electric power supply in the world is to provide uninterrupted power supply at all times to all its consumers. Although in developing countries, the electric power generated to meet the demands of the growing consumers of electricity is insufficient hence instability and outage. Power instability or outage in general does not promote development in the public and private sector. The inventors do not feel s...

Effect of Crushed Concrete as Coarse Aggregates in Production of Concrete

ABSTRACTIn the face of a possible scarcity of natural aggregates in the future in line with sustainable construction, this research investigates the feasibility of the use of recycled coarse  aggregates as an alternative to natural coarse aggregates in structural concrete. The recycled coarse aggregate used in the research was processed from waste concrete. The percentage of recycled coarse aggregates by weight of all in aggregates in the test mixes were 0%, 5% 10% 20% and 30 % res...

Hydro geochemistry and Engineering Geology of Adeta Area, Ilorin, North-Central Nigeria.

ABSTRACTA study on hydrogeochemistry and quality of shallow water and engineering properties of soil around the Adeta area in Ilorin was carried out based on data obtained from the field and laboratory. Groundwater flow, descriptive, and multivariant statistical analyses, piper, stiff and durov diagrams, as well water quality indices were used to describe hydrochemistry and water quality suitability of the area. Grain-size distribution, Atterberg limit and permeability indices were used to de...
