In this work,theproperties of short okra-glass fibers reinforced epoxy hybrid composites were studied. Critical fiber length of the okra fiber was studied at different lengths (10mm, 20mm, 30mm, 40mm and 50mm). Fiber length of 20mm exhibited the best optimal property values. The properties obtained were Tensile strength value of 10.7MPa, MoE value ... Continue Reading
The physical and chemical modifications of gum arabic have been attempted. The physical method involved the p1asticization of gum arabic with sorbitol, glycerol and ethylene glycol . The chemical method was by acid hydrolysis, acetolysis and acetate formation. The films Cast from the modified and untreated gumarabic so1utions were subjected to stre... Continue Reading
The thesis aims at studying the quality of the sandcrete blocks produced in Kano State and as such journals, codes, standards and other research materials were consulted and looked into carefully. The tests carried out include development strength test (wet and dry), wet compressive test, drying shrinkage, moisture movement and density in accordanc... Continue Reading
As a result of the need to minimize the huge losses of perishable agricultural crops produced in the rural communities and preserve their fresh qualities before getting to the consumer, at the farm and market levels, a storage system for fresh tomato was designed and constructed with the locally available raw materials. The storage system works on ... Continue Reading

The addition of traces of chemicals in the stabilisation and modification of expansive soils have been a common practice. Basically, lime (hydrated lime and quick lime) have been found to be most effective in reducing the swelling properties of potentially expansive soils. In regions where lime is scarce, cement has been found to be a suitable alte... Continue Reading
The study of the transient stability enhancement capability of Unified power flow controller (UPFC) in a multi-machine power system is presented. The test system was Nigerian 330kV power system and the focus was on the effect of disturbances on the largest generating unit (Egbin) in the system. The original network was reduced to retain the area of... Continue Reading
Natural light is the essence from which all color reacts and takes existence. It's the all important element in interior design/architecture. It provides a space with genuineness and without it a room can look unexciting, uninteresting and can feel repulsive. Sunlight is an elemental part of our existence and a fundamental component of green design... Continue Reading
Nigeria is faced with high import of petroleum products, incessant shortage of the products and poor petroleum refining status. There is therefore the need to develop local technology in petroleum refining as a sustainable solution to these problems. This work contributes its own quota to this worthy course by designing and fabricating crude distil... Continue Reading
Zeolite Y was synthesized from Kankara kaolin using a novel split method. The zeolite Y synthesized was thermally stabilized by impregnating with rare earth metal. Catalytic cracking catalysts; catalyst Y zeolite and catalyst Y zeolite + ZSM5 blend were formulated. The physiochemical and thermal properties of the raw and intermediate materials, zeo...

A research project dealing with the determination and monitoring of subsidence (vertical movements) of A.B.U. Dam as a result of increase in volume of water in the reservoir, causing sudden load (causative effects) on the dam is discribed. It is of great interest and importance to design a program to detect, direction of these movements so as to pl... Continue Reading
The medium Density Fibreboard is dry formed panel and is usually produced from lignocellulosic fibre bonded with resins. It is made from wood fibres. The purpose of this project is to investigate the suitability of cotton stalks for the production of such boards. The cotton stalks consist of the pith which is the soft central portion of the stem, t... Continue Reading

The telephone system in Nigeria has for many years been a subject of attack from many quarters. The poor performance of the system has defied all attempts aimed at improving the situation. This study seeks to identify the cause or causes of the poor performance of the telephone system in the Northern States of the country. The exchanges in use in t... Continue Reading
Comparative study of the effectiveness of some typica l arrangements of overlapping hoops to ordinary rectangula r hoop was carrie d out. The overlapping arrangements were:- Diamond Shape; Singl e Crossing; and Double Crossing (See appendix). During th e study, a fixed stirru p spacing of 300mm (Model Size 120mm) and concret e - grade of 25 was use... Continue Reading
