The use of multinomial logit models for predicting mode- choice decisions for urban travels has gained prominence in recent years. The prime advantage of this model lies in their ability to allocate travel demand among many modes at the same time, as opposed to the traditional binary mode-choice models developed in the early sixties. Journey to wor... Continue Reading
Experimental investigations have been carried out into the efficiency of a blanket design in controlling underseepage. Also, accurate numerical method for the mathematical analysis of the blanket designs for efficiency are proposed. In the experimental investigations, use was made of a seepage tank model under steady flow regimes. The blanket desig... Continue Reading
Error correction codes are widely used in almost all digital systems as they provide a method for dealing with the unknown, noise. This research has investigated the performance of error correction codes in wireless communication systems with the use of MATLAB. The error correction code employed was the convolution error correction codes. The perfo... Continue Reading

Hernias are known to have deleterious effects on the productive and reproductive performance of patient. Meshes are used in the repair of hernias with large ring, but they are neither readily available nor affordable. This study was therefore aimed at finding a cheaper alternative by comparing nylon and polyvinyl chloride (PVC) coated fibre glass n... Continue Reading
Zircon sand, a by-product of tin mining was collected from N’gell valley Tin Mining Company at 42km along Barikin Ladi road in Plateau State. The sand was characterized for activity content using NaI(Tl) scintillation detector. The activity of thorium in the zircon sand was 9726.151Â�20.16Bq/kg, while that of radium-was 538.848Â�10.08Bq/kg. The a... Continue Reading
In this research work, laboratory experiments were conducted to generate bending strengths, modulii of elasticity, moisture contents and densities of four common timber species: [Doka (Isoberlinia doka), Madaci (Khaya senegalensis) Gawo (Acacia albida) and Rimi (Ceiba pentandra)]. These timber species which are common from Northern Nigeria. Extensi... Continue Reading
Core binding properties of pulverised strands of cissus populnea plant were evaluated with the view to adding to the list of core binders available locally. The strands of cissus populnea were extracted from the stem of the plant, dried and milled to obtain a fine powder that was sieved using sieve aperture of +200. Chemical analysis of the pulveri...

A study of the effects of pressure on micro-structure and mechanical properties of die cast aluminum alloys A1350 and A380 was carried out and subsequent analysis made. Pressure was regulated at various levels in the die cast machine. Both alloys were cast into samples each under different applied pressures. The mechanical properties of both alloys...

The effects of welding and heat treatment on mechanical properties of duplex stainless steel were investigated. The duplex stainless steel rod of 8mm diameter was cut into length of 100.2mm; they were further cut into two equal parts with the two faces beveled to have a 60� grooved angle, leaving a root and face gap of 2mm. The rods were then join... Continue Reading
This study assesses the operational management and efficiency of water supply schemes in Kaduna State using a performance indicator called “Service Standard Performance Metrics (SPEM)”and SWOT analysis. The three water treatment plants in Kaduna metropolis were visited. Detailed evaluations were carried out for the schemes using some aspects of... Continue Reading
Climate Variability in Study Area, located between latitude 10Â� 15’ and 10Â� 45’ North and longitude 6Â� 15’ and 7Â� 45’ East with an area of 1647 square kilometers in Kaduna State and within the Northern Guinea Savannah Climatic/Ecological zone and its Impacts on Water Resources of the Area were investigated in this report using 47years (...

This study was carried out to produce biogas from Cow dung, Chicken droppings and Cymbopogon citratus as well as the respective co-digestion of Cow dung and Chicken droppings with Cymbopogon citratus. 25 litre digesters and gas collection systems were designed and fabricated using locally available materials. The digesters were used to digest cow d... Continue Reading
Pulverized Coal Bottom Ash (PCBA) and Superphosphate Fertilizer Processing Residue (SFPR) are capable of improving the stability of laterite soils. Varing admixture ratios of PCBA and SFPR severally with defective laterite soil from Shika area of Kaduna State produced substantial increase in the index and strength properties of the soil. The liquid... Continue Reading
