ABSTRACT The factors that affect the colour yield of an acid dye on nylon fabric were investigated at a constant temperature of 500C, usingC.I. Acid Yellow 23,with citric acid and sodium chloride as auxiliaries. It was observed from the absorbance results that the colour yield of C.I. Acid Yellow 23 improved with increase in time of dyeing, while the absence or increase beyond 1% (acid) and 5% (salt) reduced the colour yield of the acid dye on the nylon fabric. Also, at a constant dyeing ...
ABSTRACT This research work is aimed at the development of computer programs using MATLAB based on the new polynomial shape functions, for analysis of single panel and continuous thin isotropic rectangular plates. Twelve single panel plate types of different boundary conditions namely SSSS, CCCC, CSSS, CSCS, CCSS, CCCS, SSFS, SCFS, CSFS, CCFS, SCFC and CCFC for aspect ratio, s= b/a, were analyzed for pure bending, buckling and free vibration using computer programs developed in this work....
ABSTRACT Appraisal of industrial accidents and their effects on profitability are presented. Two manufacturing companies, The Nigerian Bottling company, Owerri, and the Nigerian Breweries, Aba were selected for the study which covered a period of three business years (2011–2013). Data collection was through administration of questionnaires and personal interviews of some strategic staff of the Companies. The data were analyzed using Mean Percentage Method. The results showed that th...
ABSTRACT The inhibition of corrosion of mild steel by Azadirachta indica leaf extract in acidic environments of HCl and HNO3 from pH1 to pH6 has been investigated using the weight loss technique. The Azadirachta indica leaf extract is the inhibitor and the mild steel used was in the form of coupons. The investigations were carried out at ambient temperature. The optimum concentration of the extract used for the experimentation was obtained by soaking 200g of ground fresh Azadirachta indic...
ABSTRACT This research aimed at empirical investigation of flexural strength of compressed stabilized earth slab. Two sets of 500 x 500 x 150mm compressed stabilized earth slabs were cast. One set was cast with BRC mesh of 5 x 150 x 150mm with strength of 250N/mm2 as reinforcement and the other set was cast without reinforcement. Eight mixture proportions of laterite, river sand and cement were used in this research work and optimum moisture content obtained from compaction test of the mi...
Environmental pollution is a form of land degradation which has contributed immensely to the reduction of available arable lands and could lead to the total annihilation of the ecosystem if not effectively mitigated. Bioremediation technology offers a biological means which provide an eco-friendly and cost-effective approach for soil remediation in contrast to physicochemical methods. This study aims to evaluate the application of wastewaters and air-injection for the treatment of crude oil c...
The prevalence and high rate of soil contamination have contributed immensely to the reduction of arable lands which might lead to the total annihilation of the ecosystem if not mitigated. Bioremediation employs microorganisms that offer a sustainable approach for the remediation of contaminated soils. This study focus on the evaluation of industrial (brewery) and municipal effluents for the treatment of crude oil-contaminated soil. A microcosm containing 1kg of crude oil-contaminated soil wa...
Abstract Automatic Three Phase Changer is considered one the most important element in the power distribution system as it works to reduce the problem during faulty condition time and also protecting high voltage to the consumption voltage. To achieve maximum efficiency of this phase faulty the stability of power consumption on the distribution center has a main role. This thesis aims to design, simulate and develop automated three phase changer by running different place. The system works a...
Correlation and regression in this paper were employed as analytical tools to study the degree of relationship as well as the nature and strength of the relationship between green concrete properties and percentage replacement of cement with civil engineering materials. Pearson product-moment method and Spearman’s correlation coefficient were extensively used to show how correlation analysis can be practically applied in green concrete research. Least square regression line method for b...

Abstract The aim of this work is to characterize properties and microstructure of stainless steel used as a coating on welding of carbon steel sheets. Two carbon steel plates were set as the metal base and the stainless steel coating was applied on the weld bead. The applied process used was the submerged arc welding (SAW) and tests were carried out for the tensile strength and Vickers hardness, in addition to observation of the microstructure by optical microscopy. The results indicated that...

ABSTRACT This project shows the construction of a microcontroller based security door using Smart card. It is aimed towards programming the microcontroller to control the Hardware in sliding door. The system consists of a microcontroller 89S52 which Sends a signal to the multiplexers on insertion of the smart card in the card slot. The multiplexers consist of ICS which prompts for a display of the identity of the Card user in the liquid crystal display (LCD). The LCD displays the status of th...
Abstract My project is to improve JIT store management system from manual to automated system. Which is used to avoid problem faced by store keeper when store material manually. Store is the place where many varieties of materials are kept for the purpose of work. So at a time of storage is hard to write in document all material listing by their name, id, model, price and quantity; and is also boring to search specific material from whole material for human being but is easy for computer ...
Abstract: Technology in our contemporary world has a whole lot of applications and has completely revolutionized the way we do things. Almost every quarter of a year something new that helps humans carry out activities in a simpler and efficient way is developed. With the level of advancement in the area of internet and computing, one can now successfully stay at home and learn or learn while on transit. This paper contains important information on how online learning otherwise known as E-lea...
