This thesis describes the use of heuristics and cost models based on the queueing theory to determine effective crew size for maintenance operations. The model was applied to mechanical maintenance workshop, Federal ...

The scarce water resources of Southwestern Nigeria could be better managed, if reliable forecast of river discharge through rainfall variability data over a long period are available. The study was aimed at carrying out ...

This study is on the use of palm oil sludge as binder in the production of sawdust briquettes. The specific objectives of the research are to establish the optimum proportion of palm oil sludge as binders, determine the ...

The level of tillage mechanisation in south-west Nigeria is low because of the high cost : benefit ratio of tillage machinery. This is due not only to few hours of tractor utilisation per annum, but also due to the low ...

Evapotranspiration (ET) rates have been reported to be decreasing in many parts of the world and this scenario had been attributed to the effect of climate change/variation. This study analyzed this phenomenon in the context ...

Safe water availability is a critical problem in the post- rainy season in Akure, humid Southwest Nigeria. The potential of rainwater as a sustainable option for solving the problem of seasonal water shortage was assessed. ...

Soil water is the major limiting factor to the production of Corchorus olitorius especially during the dry period. Two field trials (experiments I and 2) were conducted between March and April, 2000 and between September ...

Landlocked States in Nigeria are daily faced with the reality of the need for rapid agricultural development for socio-economic transformation. The magnitude of the need for most of the States requires massive mechanisation ...

Hydrological data namely: the total annual discharges and the gauge heights. spanning 18 years (1982-1999) were obtained from Ogun-Osun River Basin and Rural Development Authourity, Abeokuta. The hydrograph and rating curve ...

This work presents a mathematical model of gari drying in which diffusion of water, moisture evaporation, heat and mass transfer through tile porous solids were taken into consideration. Several tests were run using a ...
