The Effect Of Particle Size And Particle Size Distribution On The Modulus Of Rupture Of Some Nigerian Clays
ABSTRACT The effects of particle size and particle size distributions of three clay samples, on their modulus of rupture were studied. The three clay samples were collected from natural clay deposits at Nsu; Ohiya- Umuahia; and Awo-Omamma all in south eastern Nigeria. The particle size analysis of the clay samples was done by laser diffraction in wet suspension mode and the results disclosed that Awo-Omamma clay has greater proportion...
The Economics Of Crude Oil Stabilization
ABSTRACT Estimating the gas/VOC emissions from oil and gas producing equipments has been a goal which the industry and regulatory agencies have spent a great deal of study and effort to contend with. This research estimated the flashing losses of gas/VOC emission from conventional atmospheric storage tanks to the atmosphere using Vasquez-Beggs Equation (VBE). Using VBE confirmed observed losses experienced in the industry as is represented in a graph showing the losses. It went further to q...
Synthesis And Characterization Of Biofuels From Various Nigerian Crops For Internal Combustion Engines
ABSTRACT Bio-fuels (Biodiesel and Bio-ethanol fuels) are synthesized from various Nigerian crops (palm(Elaeis Guineensis) wine, raffia(Raffia Vinefera) trunk, sugar cane(Saccharum L), physic nut seed (Jatropha Curcas), castor bean seed(Ricinus Communis), sandbox seed (Hura Crepitans) and African bush mango nut (Dika Nut) (Irvingia Gabonensis)) to serve as alternative fuels for internal combustion engines. The direct base-catalyzed trans-esterification process is employed in the biodiesel pr...
Supply Chain Management In Nigeria: The Role Of Freight Forwarding
ABSTRACT The study examined the role of freight forwarding in supply chain management in Nigeria, with particular reference to time and cost in cargo clearance. Freight forwarding has been portrayed by many authors and public as contributing little or nothing to the economy as a whole. It is based on this dysfunctional premise that the study investigated the time and cost of clearing by freight forwarder and self clearing option stipulated by the law. Freight Forwarders and Su...
Study Of The Properties Of Some Local Clays For The Production Of Floor Tiles
ABSTRACT The suitability of some clay deposits in South Eastern Nigeria (Unwana, Ekebedi, Okigwe and Nsu) as materials for the production of floor tiles was investigated. The clay samples were analyzed using wet classical method to determine their chemical composition. Floor tile test specimens were produced using standard method. The test specimens were tested for physical properties such as compressive strength and porosity at 10500C and 11500C temperature levels. The chemical analysis ...
Studies On The Effect Of Produced Water On Juvenile African Catfish (CLARIAS GARIEPINUS)
ABSTRACT This study investigated the effect of produced water from an oil exploration company in Rivers State on the blood, gills and liver of Juvenile African Catfish (Clarias gariepinus). Seventy Juvenile African Catfish were separated into 7 groups (10 per treatment) and used for the study. The juveniles were exposed to three varying concentrations of fresh and stale produced water (2.5ml/l, 5.0ml/l and 10.0ml/l) for a period of 3weeks. At the end of the test period, haematological, bioc...
Structural Characteristics Of Soilcrete Blocks
ABSTRACT This work investigates the structural characteristics of soilcrete blocks (lateritecement blocks and laterite-sand-cement blocks) produced with locally available and affordable laterite. Scheffe’s simplex method and Osadebe’s regression theory were used to formulate mathematical models for optimisation of properties of soilcrete blocks which include compressive strength, split tensile strength, shear strength, flexural strength, Poisson’s ratio, modulus of elasticity, shea...
Stresses Resulting From Fluid Flow In Pipes
ABSTRACT The determination of the components of stress on a pipe made of either linearly elastic or non-linearly elastic material and subjected to internal fluid pressure is of immense benefit to engineers. Chung et al [2] worked on a class of non-linearly elastic type with some degree of success. This work seeks an improvement on [2]. It will do this by obtaining such components of stress in a form that engineers will find easy to use. Towards obtaining the required components, the r...
Software Development Of An Electronic Medical Record System For Health Services In Nigeria
ABSTRACT Almost all over Nigeria today, manual method of Hospital Record Keeping is the practice. No serious attempt has been made to join the Information Society by adopting new information technologies in a vital area like record keeping. This project, therefore, set out to investigate the drawbacks of manual methods on health service delivery, and subsequently designed an automated system to replace the manual method. Through participant observation and personal interview, data...
Signal Strength Evaluation Of A 3g Network In Owerri Metropolis Using Path Loss Propagation Model At 2.1ghz
ABSTRACT This work evaluated the path losses and strength of received signals of a 3G Network operating at frequency of 2.1GHz in Owerri metropolis using Drive test. There were serious cases of call drops and low Quality of signal (QoS) experienced within some part of the Owerri metropolis. This situation has been burdensome on the side of the network users, as that has made them incur a lot of financial losses and passed through pains. The network providers, on their side, also passed thro...
Role Of Maternal, Child And Environmental Factors On Patterns Of Malaria Morbidity In Under Fives In Abia State
ABSTRACT Malaria, a preventable disease, caused by a protozoan parasite, accounts for about 300-500million clinical cases and two million deaths world-wide annually. Ninety per cent of this occurs in countries south of the Sahara. It is responsible for about 25% of all childhood mortality. It is estimated that at least 50% of the population will have at least one attack of malaria in a year. It is one of largest contributor to disease burden in Nigeria. There were two million cases of malaria...
