ABSTRACT Monosodium Glutamate is a widely used food additive and flavor enhancer that is present in most soups, salads and processed meat and also present in packaged food without appearing on the label. This could result to inadvertent consumption of monosodium glutamate in high concentrations. The present study investigated the effect of monosodium glutamate on liver and testes of adult male wistar rats, by daily oral exposure of different doses. Wistar rats (n=20) of the average weight of ...
ABSTRACT Nitrification is the biological oxidation of ammonia into nitrite, followed by the oxidation of nitrite into nitrate by small groups of autotrophic bacteria and Achaea. NH3 removal is beneficial to the plant system as build up is dangerous. Presence and activities of ammonia oxidizing bacteria (AOB) and nitrite oxidizing bacteria (NOB) in freshwater fishpond of a circulating aquaponics system was examined in respect to random points in the aquaponics system (the fish tank, the bio-fi...
ABSTRACT The use of ethanol in fuel blending has long been in use, and this help in controlling gas emissions but cannot be compared to bio-ethanol in control of greenhouse gas emissions. Bio-ethanol is known to adsorb CO2 they emit; it also improves rural economy. A lot of materials especially starchy crops are used in the production of bio-ethanol. This research work focuses on the production of bio-ethanol from molasses; a waste from sugar cane industries. Bio-ethanol is regarded as one of...
ABSTRACT Over the years, there have been persistent and consistent issues bordering on security in the Murtala Mohammed International Airport, Ikeja, Lagos. As an International airport as well as the gateway into our Country, it is expected to measure up to international standards in facilities, personnel, services, security, safety etc but unfortunately most of these areas are atimes neglected and consequently fall below acceptable international standards. This research has been designed...
In this study of designing a wind turbine using wind energy potential, a case of FUTA. Weibull distribution function method was adopt with the help of probability density function and cumulative density function analysis, the wind speed characteristics and energy potential of the study area was investigated using hourly wind speed data that span between 1 and 12 months (1year) and measured at a height of 10 m. Hellmann power law was used to derive the wind characteristics of the study area to...
Abstract This project outlines the structural design of eight-storey reinforced concrete hostel building following British standard, BS: 8110, part 1, 1997 “Structural use of Concrete”. The project aimed at producing structural design of eight storey hostel. The research was achieved based on the objectives of; developing structural layout from the architectural drawings; analyzing and designing the structural elements with some degree of economic consideration and producing the structura...
This project proposes the use of a propellers to power a lightweight vehicle as a non-conventional means of transportation within the school environment. Propellers work based on the generation of thrust sufficient enough to move a mass (in this case, a lightweight, three-wheeled vehicle) to which it is connected. The propeller powered vehicle makes use of this thrust generated as the basic source of power needed for acceleration. Although there already exist various works on the development ...
ABSTRACT The construction industry is known to be highly fragmented in that it requires the inputs of numerous parties to deliver a project. The fragmentation of the construction process necessitates effective integration of the numerous parties and the major tool for achieving this integration is effective communication. This study investigates the communication tools used in project delivery, key indicators of team integration in construction proje...
Background of the Study: Every construction company all over the world expects not only to break even in every project undertaken, but to also make a reasonable level of profit that will satisfy the owners of the company. This is only possible if the activities involved in undertaking any particular project are optimized, viz-á-viz the factors of time, cost and quality are successfully brought into optimal play, which defines the success of the project. But until construction project...
ABSTRACT The study focused on maintenance management practice in public and private properties, (a case study of selected public and private housing estates) in Lagos state, Nigeria. To achieve this, case study of 10 selected housing estates were carried out by means of structured questionnaires. A total number of 200 questionnaires were administered to the selected estates and 141 were returned and used for the analysis, and this gave a response rate of 70.5%. Th...
CHAPTER ONE INTRODUCTION 1.1 Background Of The StudyPassengers leaving on a trip normally want to spend as little time as possible in theterminal. They want to have baggage carts readily available, a fast check-in, and little timewaiting before and quick boarding prior to a timely departure. Passengers do not appreciate longline-ups, repetitive security checks, crowded departure areas, line-ups for boarding and a delayeddeparture. The rise in terrorist activity requires more stringe...
ABSTRACT In recent years there has been an increase in the number of construction works and concrete is the main construction material for most of the structures that are being built. Nigeria is a developing Country with a large population and land area therefore a consumer of concrete. This paper considers the option of recycling concrete in order to meet the high concrete demand and effective management of construction and demolition waste. The test focused on the use of recycle...
ABSTRACT This study was carried out on the factors that influence the choice of inventory control methods in organization. The specific objectives were to determine how Organization policy, Information Technology and employee competency influence the choice of inventory control methods. The study was conducted at Menengai Oil Company Nakuru .The theories were used to support the objectives of the study among them are classical organization theory and competence theory. Survey research design ...
ABSTRACT Minimizing Haulage Roundtrip Distribution Cost of Manufactured Products is a major concern in the haulage industry. The success of each trip requires for a truck owner or fleet manager of a haulage company to assign to the truck driver the resources needed for the job success. However, on close examination, the fuel for the return trip and a tangible percentage of the road expense budget achieves little but to bring the truck back to the yard. These resources are not engaged on the ...
ABSTRACT This research project “Network Analysis as an effective maintenance planning tool” created a detailed evaluation of strategies and techniques for planning maintenance activities in the Nigerian process industry, laying focused emphasis on operations of Warri Refinery and the effectiveness of CPM Network analysis. A review of previous works related to maintenance planning was extensively undertaken and findings revealed the extent in which planning activities has been carried ...
