ABSTRACT Earth dam failures could result in the loss of lives, damage to properties, health, environmental and social problems. Distressed dams cost a lot of resources and inconveniences to remediate. There is paucity of data on failures and distresses of many earth dams located in the north-eastern part of Nigeria. This study was designed to determine the geological, hydrometeorological, engineering factors and soil properties responsible for the failures and distresses of earth dams. A tota...
ABSTRACT Locally processed rice (Oryza sativa L.) is characterized with high percentage of broken grains and impurities which impair the quality and reduces the market value. Reducing the proportion of broken rice and impurities after milling remains a challenge. There is therefore a need to develop a machine which cleans and grades the rice kernels based on quality. The objective of this work was to develop a cleaner - grader to improve the quality of milled rice. The physical and aerodyna...
ABSTRACT Tomato (Lycoperscium spp.) is an important component of daily dietary intake with seasonal and geographical variation in its production. They are usually in short supply in the dry season and effective storage in the fresh state still poses a challenge. Pre-treatment methods have been reported to improve drying characteristics of fruits and vegetables but there is dearth of information on drying of indigenous variety of tomato despite its high nutritional value. Pre-treatment methods...
Abstract The prevailing wind speed and direction in an environment are critical factors in farmstead planning as they influence the appropriate location and orientation of structures in order to reduce wind load impact and promote a healthy environment. The failure of farm structures especially with roof blown-off arising from wind load has become rampant in Ibadan environ in recent time and an urgent solution is desirable. In this work, an attempt is made to develop a wind rosette for Ibadan...
Abstract: Fruit trees am hardly ever sought for their wood until recently. Fruit trees like C. alhidum is now being used for structural and non structural purposes in city suburbs, This study investigated wood properties and few tree chplracteristies of C. albidum grown in AkinyeIe Local Government h (ALGA), Ibadaa, Oyo State, Nirk The dm was to mitigate, the dearth of information on these &atut.cs in elation to its utitdon. Samples %re collected from five emerging settl&ents in the; study ar...
ABSTRACT Celosia Argentea was planted on Agricultural and Environmental Engineering Department experimental field.
ABSTRACT Merchantable trees in the tropical forest are usually widely scattered and the cost of road construction and logging operations are expensive.
ABSTRACT Soilless farming of vegetables in greenhouse has become a profitable venture in some parts of the world. A high degree of competence in engineering skills, irrigation techniques and cost reduction is required for its successful operation. In Nigeria, the potential of soilless farming in greenhouses has not received adequate attention. The use of soilless media and appropriate irrigation system to produce marketable tomato in a greenhouse were investigated. Roma VF variety of tomato...
ABSTRACT Irvingia gabonensis and Irvingia wombolu are species of bush mango commonly found in Africa whose kernel are processed into soup. Literature generally abounds on the nutritional composition of the fruits and kernel but there is dearth of information on the engineering properties which are very important in the design of processing equipment and machines. This study was designed to investigate the influence of moisture on some engineering properties of seeds and kernels of I. gabonen...
ABSTRACT The increasing incidences of roof failures especially blow-off in recent times in Southwestern Nigeria has become worrisome in view of the damage done to adjacent structures and danger posed to building occupants and owners. There is the urgent need to devise methods to curtail failures and minimize the incidences of blow-off. This study was designed to investigate the causes and patterns of roof failures, recommend curtailment measures and develop a model to predict roof blow-off. ...
ABSTRACT The efficiency of the poultry waste water treatment plant of Zartech Limited, Ibadan, Nigeria was assessed based on percentage reduction on the various water contaminants while the unit cost of treated water was compared with that supplied through tankers.
ABSTRACT Silos are the most appropriate structures for the bulk storage of grains.
ABSTRACT Agricultural water management systems aims to provide crop water requirements to sustain optimum yield.
ABSTRACT The paper simulates the sensitivity of maize crop yield response to temperature increase with appropriate irrigation scheduling that may obviate the negative impact of temperature increase on crop yield.
ABSTRACT A lot of wood waste is generated from wood species in the Nigerian wood mills which are hazardous to the mills, mill workers and the wood.
