Abstract Nowadays, the natural material as agriculture waste in concrete has long been discussed. Coconut shell is one of the most vast and readily available agricultural solid waste in many tropical countries. The properties of coconut shell are examined and the use of coconut shell aggregate as construction materials are evaluated. This study focused on the effect of coconut shell as fine aggregate replacement on the performance of concrete in terms of the mechanical properties and physical...
Abstract Shelter is a basic human need. Unfortunately, decent shelter for the masses; the poor have not materialized over the years. The cost of concrete materials in building and civil engineering project has been a concern to the society. These and other things led to the research on Biological local materials that are dumped as waste in our environment, causing pollution and congestion as substitute materials. Therefore, this research work was carried out in respect to that and the researc...
ABSTRACT This study investigated the effect of rainfall on the physical, chemical and bacteriological quality of some selected hand-dug well water consumed by students of Ekiti State University, Ado-Ekiti. To this effect, six (6) samples from three (3) hand-dug well used, labeled (Ab, Bb, Cb & Aa, Ba, Ca) indicating before and after rainfall respectively were collected and examined for both the bacteriological and physio-chemical parameters. The bacteriolo...
ABSTRACT The study of heavy metal deposition and accumulation in fabric production vicinity is of increasing interest because of the awareness that heavy metals present in soils may have negative consequences on human health and the environment. This study describes the assessment of heavy metal concentration in soils of fabric production vicinity a case study of Itoku Adire Kampala market, Abeokuta, Ogun State, Nigeria. Five (5) top soil samples and 5 sub soil samples were collected rando...
The sole purpose of this project work is to determine the settlement characteristics of soil for the construction of building, a case study at FUTO Senate Building area and FUTO NDDC hostel area, other objectives are the classification of the soil, determination of the strength properties of these soils and also making of sundry recommendations about the type of foundation most suitable for the construction of buildings on these soils. Soil samples were collected from FUTO Senate...
Abstract It is of no doubt that one day, fossil fuels, which the whole world highly depends on, will come to a halt in a few decades to come. To this reason, researches have been geared towards alternative sources of energy: biodiesel, a form of renewable energy (energy that can be regenerated once used up), is one that has been made known and being tested in some parts of the world. Due to the fact that biodiesel is hygroscopic (absorbs water readily from the atmosphere), as well as other fa...
Natural gas is one of the major sources of fuel and raw material to industries all over the world. However, it contains some acid gases such as CO2 and H2S which are corrosive and harmful to the environment. These acid gases must be brought to permissible limits to promote safety in the operation and increase the heating value of the natural gas. In this project, we design an acid gas removal plant based on the amine treatment process using ASPEN HYSYS software. In our propose...

This write-up gives an overview of lubrication, lubricants, their types and general properties, and the principles of lubricant application. It further emphasizes on the different methods of lubricant application, specification, selection and storage.
ABSTRACT The study aimed to assess the quality of drinking water in Olowotedo community of Ogun state, Nigeria. Five samples were taken from different sources (wells, borehole, tap and sachet water) were analyzed, Selection of water samples was carried out using proportionate allocation, equal allocation, simple random sampling and systematic sampling methods depending on the stage. The water quality parameters examined and their results for all the five water samples were; colour having...
The energy generation and power consuming loads at Brass LNG facility located in Brass Island, Bayelsa State Nigeria were analyzed and compared with expected demand changes and means of minimizing cost and greenhouse gas emission were also proffered with wind and solar energy penetration into the overall power mix . The wind and solar hybrid power generation system reduced the fuel consumption, greenhouse gas emission and noise pollution by the generators and turbine by relieving some of the ...
Since the inception of the Private Finance Initiatives (PFI) in the United Kingdom, Government are increasingly adopting it as a means of proving infrastructure to the public neglecting the traditional procurement methods which relies completely on the public finance. Private Finance Initiative (PFI) is a method of contract procurement where the private organisation provides an infrastructure, finances, operates and maintains the infrastructure. This is done by transferring the risks involved...
ABSTRACT The AVR is automatic voltage regulator and it is a device which is used to regulate or stabilize electrical power supply for electrical or electronic appliances In this project, therefore, we are interested in the construction of this all important device. Furthermore, we shall discuss the techniques, processes, switching stages and then the working principle of the automatic voltage regulator Chapter one of this project dwells on the introduction of the pr...
ABSTRACT Automatic voltage inverter is an important area in power system engineering. It is the process of using a 12v DC from the battery to achieve a 220/230V AC through the help of oscillator, drivers, power transistors and transformer. The stages are battery to oscillators, oscillators to drivers, drivers to power transistors then from power transistors to transformer which is capable of giving out 220/230V (1000w) as an output. A 1.25KVA (1000w) voltage inverter was construct...
Voltage stability is a major concern when planning and operating electrical power systems. As demand for electric power increases, power systems are stressed more and more. Since the construction of new transmission lines is very expensive, and the right of way requirements are not easy to come by, a cost-effective policy is to use the existing lines to their maximum thermal and stability limits, and this requires optimum sharing of power flow in the system. Flexible AC Transmission Systems ...
