DESIGN AND CONSTRUCTION OF ICU/REHABILITATION ADJUSTABLE BED USING LOCALLY SOURCED MATERIALS

The focus of this project was the development of an ICU/Rehabilitation adjustable bed for the hospital and home environment. The project was initiated with the desire to develop an innovative, effective and inexpensive mechanism that would require an electrical supply. The design was performed systematically using various methods, procedures, techniques and materials to aid the process. One of the method used is carpentry, which was used to make the bed framework and the adjustable floo...

Corporate Social Responsibility: A Case Study of Royal Dutch Shell in the Niger Delta

AbstractAccording to Nasin et.al, 1997: ‘CSR  issues progresses from a period in which the issue was thought of to a period of increasing awareness and expectation for action and then to a period when new standard for dealing with issues become ingrained in the normal functioning of the company’This research work highlights shell’s CSR in the Niger delta region which has and is still facing a lot of issues which encompasses what Nasin et.al had stated. These issues began sub-conscious...

DESIGN & CONSTRUCTION OF HAMMER MILL MACHINE

Processing involves conversion of raw materials into varied forms of finished products. It is carried out in different fields of science and engineering. Agro and Agro allied industry, food manufacturing, pharmaceutical, ceramic, civil engineering industries etc are involved in processing. The breakdown of large stones to an acceptable size for road construction is the business of the quarry industry (civil engineering). The grinding (milling) of clay materials for the purpose of production o...

The effect of rainfall on the quality of hand dug well water

                   ABSTRACTThis 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 bacteriological...

ASSESSING HEAVY METAL CONCENTRATION IN SOIL OF FABRIC PRODUCTION VICINITY

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 colle...

Bearing Capacity and Settlement Characteristics of Soil: A case study of FUTO Senate Building & FUTO NDDC Hostel Area, Owerri, Imo State.

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  Sen...

Corrosion Studies of Mild Steel in Biodiesel Obtained from Ghee Butter (Mann Shanu)

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 fact...

Simulated Design for the Removal & Recycling of Acid Gases from Natural Gas

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.     ...

BASIC LUBRICATION PRINCIPLE

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.

QUALITY ASSESSMENT OF DRINKING WATER SOURCES (STUDY OF OLOWOTEDO COMMUNITY, OGUN STATE)

ABSTRACTThe 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 0...

Energy Audit, Optimisation and Management of Liquefied Natural Gas Plants with Renewable Energy Resources Around the Plant: A Case Study of Brass LNG, Brass Island, Nigeria

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 o...

EFFECTIVENESS OF PORTSMOUTH HIGHWAYS PRIVATE FINANCE INITIATIVES (PFI) SCHEME

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...
