Buckling Analysis Of Plates Subjected To Biaxial Forces Using Galerkin’s Method
ABSTRACT This work studied the buckling analysis of plates subject to biaxial forces using the Galerkin’s method. Twelve boundary conditions were considered. The plate deflection equations were obtained using the polynomial series, and from the plate deflection equations, the expression for the critical buckling loads of the different plate boundary conditions were obtained for different aspect ratios, ∝ using the Galerkin’s functional. The aspect ratios, considered throughout...
Buckling Analysis Of Isotropic Rectangular Plates Using Ritz Method
CHAPTER ONE INTRODUCTION 1.1 BACKGROUND OF STUDY Buckling analysis of isotropic rectangular plate has been a subject of study in solid structural mechanics for more than a century. Many exact solutions for isotopic plates have been developed. Steel rectangular plates are widely used in buildings, bridges, automobiles, and ships. Rectangular plate has width size comparable to size of their lengths and so is modeled as two - dimensional plane members unlike beams and columns. Un...
Biosorption Potentials Of Zea Mays Cob And Musa Paradisiaca Peels In The Treatment Of Waste Effluent From Paint Industry.
ABSTRACT Studies on the biosorption potentials of Zea mays cobs and Musa paradisiaca peels in the treatment of waste effluent from paint industry, was carried out. Standard laboratory procedures using 400 ml of the effluent were adopted to assess the values of Pb, Fe, Cland PO4, BOD and TDS at pH 6.7 and pH 10.0 before and after treatment of the effluent with 1g and 3g of pulverized corn cobs and plantain peels. Standard procedures were adopted for the phytochemical screening of the...

Extracts from roots and seeds of Moringa oleifera and Jatropha curcas were tested at 10% concentration and sprayed after 2,3 and 4 weeks in three different growing periods of groundnut; 2, 3 and 4 weeks. Some plant extrated were mixed with 3ml of an emulsifier made from castor oil known as RIMULGAN and then separately added to e...
Banking Sector Instability In Nigeria: Impact On The Economy (1980 – 2011).
ABSTRACT Most of the studies relating banking activities and macroeconomic behavior of many nations focused on the effect of macroeconomic instability on banking sectors. This study rather examines the impact of banking instability on the Nigerian economy. Annual data were used ranging from 1980 to 2011 drawn from various data publication issues domestically and those outside the country. Variables taken into consideration in the course of analysis are those proxies to the banki...
Bank Performance And Credit Risk Management
ABSTRACT This study investigates the effect of credit risk management enhances on the performance of the Nigerian banking industry with specific attention on management efficiency measured by return on asset (ROA) and return to shareholders measured by return on equity (ROE). The study is motivated by the increased concern based on research findings which seem to have isolated increasing portfolio of non-performing credit as a casual factor of bank failures globally. The validit...
Bacteria Corrosion Of Mild And Medium Carbon Steels
ABSTRACT Investigations were carried out to determine the corrosion effect of sulphur-reducing bacteria on mild and medium carbon steels. Specimens were exposed to anaerobic, aerobic and distilled water environments. The corrosion rates were evaluated at intervals of seven days using weight loss and electro-chemical methods for a period of forty two days. The specimens were also subjected to visual examination and the result indicated uniform corrosion in all the environments....
Assessment Of X-Ray Radiation On X Ray Workers And Associated Potential Health Problems In Owerri
ABSTRACT A study on assessment of X-ray radiation among X-ray workers and associated potential health problems in Owerri was carried out with the thermolumolunescent dosimeter between 12th April to 30th December 2011. A total of 50 workers were used for the study. Comprising 24 male X-ray workers and 26 female X-ray workers. The mean X-ray dose below permissible doses is 9.4.7 the T-test is -4.29; the P-value is 0.000. The mean exposure factor is 20msv upto six test which invo...
Assessment Of Variation In The Concentration Of Heavy Metals In Groundwater Within Oil Producing Community Ogba/Egbema/Ndoni L.G.A. Rivers State
ABSTRACT Groundwater constitutes a major source of potable water supply foragricultural, industrial and domestic applications. This has led to the increase in the demand for ground water exploitation. Borehole water being an ideal source of portable water supply has been employed to meet this teeming demand. For the purpose of this research, borehole water was adopted as a sample model for the experiment to determine the extent of heavy metal contamination in the ground water of...
Assessment Of Training Neeeds And Challenges Of Mainstreaming Electronic Media Production For Extension Services In Imo State
Abstract The advancement in electronic media is increasingly liberalizing the dissemination of agricultural information, such that farmers can now on their own access information before ever they are communicated to them by extension agents. Therefore, for extension to maintain its relevance and functions, extensionists must acquire the skills/abilities necessary to maintain/control what (contents) farmers are sourcing from the media. In the light of this, the study was designed to...
Assessment Of Post-Spill Impact On Soil, Case Study (K.Dere) Ogoni Land
ABSTRACT The supply of food, water, and agricultural resources is fast becoming a difficult issue. This is because the resources are heavily polluted as a result of intensive crude oil spill, and oil related activities in the state. This study focused on the assessment of soil samples from Ogoni, (k- Dere) community. To ascertain the level of pollution that may have occurred. Different parameters were analyzed, namely pH, total petroleum hydrocarbons, nitrate, phosphate, sulphate,...
Assessment Of Port Performance: The Queuing Theory Approach (A Case Of Apapa Port Complex)
ABSTRACT This research focused on assessing the port performance: the queuing theory approach using Apapa port complex (APC) as the case study. The research was designed and carried out to answer among others the following questions: to assess the level of vessel turnaround time, traffic intensity, the waiting time of calling vessels at the port? Also, to determine the probability of vessel queuing on arrival at the port? To answer these questions only primary means of data collect...
Assessment Of Nutritional Quality Of Market Samples Of Fruit Drinks In Owerri
ABSTRACT Nutritional quality of market samples of some fruit drinks were assessed through laboratory analysis. The assessment covered the determination of quality parameters of six brands of fruits drinks which include California brands of orange and pineapple drinks, orange and pineapple fruta drinks and 5 – alive orange and pineapple drinks.

Assessment Of Groundwater Quality Around Abandoned Quarry Ponds Near Lower Benue Trough, Nigeria
ABSTRACT A field study was conducted on the Assessment of Ground Water Quality around Abandoned Quarry Ponds near Lower Benue Trough, Nigeria. Water samples were collected using 1liter amber glass bottles each fitted with a screw cap and lined with foil from the four abandoned quarry pits measured fifty meters (50m) (165ft) deep. These were labeled ABP1, ABP2, ABP3, ABP4, while the wells were labeled HDW (hand dug wells) measured eighty meters (80m) (264ft) deep and BH (borehole),...
Assessment Of Airport Productivity Andefficiency In Nigeria
ABSTRACT This study assessed the productivity and efficiency of airports in Nigeria employing the method of Data Envelopment Analysis (DEA).Two variants of DEA models were estimated and their outputs compared in order to enhance the robustness of the study. These models include the one based on Constant Returns to Scale (CRS) to characterise the input-output combinations and that based on Variable Returns to Scale (VRS). It is sometimes argued that DEA models generally tend to overe...
