ABSTRACTThe Project work presents an Optimum design of welded plate girder. A simply supported plate girder with span of 15meters was chosen for the case study. The girder was subjected to a self-weight of 50KN/m and concentrated loads of 1000KN at 5m and 10m from the left support. The plate girder was analysed to get the design moments and shear forces. An initial manual design was carried out for the plate girder in accordance with BS 5950-2000. From the design, initial section parame...
The study aimed at identifying animal manure which influences soil health indicators (microbial abundance), was conducted at Lilongwe university of Agriculture and Natural Resources (LUANAR) crop and soil science student farm. The experiment had four treatments; cattle manure., goat manure,pig manure and chicken Manuel. Treatments were arranged in RCB replicated three times. The ANOVA shows that there was significant difference (p
Abstract: This paper examined the basic engineering and geotechnical properties of poor subgrade soils using woven geotextile to stabilize it and to also deal with the problem with lime under soaked conditions, it is intended at increasing the strength and mechanical properties of the soil even in extreme conditions. This is considered to be of great importance in civil engineering works as road structures need to be catered for during rainy season. Subgrade soils, it...
Global health issues have awakened Engineers to looking into the causes of most health challenges and looking for ways to improve health status of humans. Research has shown that poor water contributes to most human health challenges. Water contributes perhaps most importantly to everything called existence. Virtually everything requires water. All living things depends on water to survive, which varies from one organism to another based on sizes, and many other factors, hence, need to provid...
ABSTRACTNowadays, the destruction and pollution of humane environment has produced an ever growing awareness worldwide of the need for more effective sedimentation processes. The main aim of this project was to design and fabricate an experimental sedimentation rig with the objective to determine the rate of settling against time using calcium carbonate as a test sample.The rig consists mainly of the cylindrical tank, valves, motor, stirrer, and the sight glass. For the test run, 82 litres of...

The noise pollution is a major problem for the quality of life in urban areas. This study was conducted to compare the noise pollution levels at busy roads/road junctions, passengers loading parks, commercial, industrial and residential areas in Ilorin metropolis. A total number of 47-locations were selected within the metropolis. Statistical analysis shows significant difference (P < 0.05) in noise pollution levels between industrial areas and low...
A l’heure où la viande constitue un aliment de luxe pour les populations pauvres, les légumineuses entre autres le soja constituent une alternative. Malheureusement, sur les sols fortement altérés de Lubumbashi, son rendement demeure de loin inférieur au potentiel même de la culture. Les effets de compost de Tithonia diversifolia sur la croissance et le rendement de soja ont été étudiés au cours de la saison culturale 2013-2014 sur un sol dégradé de Lubumbashi (R....
Assessment of the response of maize (Zea mays L.) planted between hedgerows of Tithonia diversifolia in Lubumbashi, DR CongoObjective: Two trials were carried out over time at the Centre de Recherche Agroalimentaire (CRAA) and aimed at evaluating the behavior of maize cultivation in hedgerows of Tithonia diversifolia (Mexican sunflower).Methodology and results: The experimentation design was a completely randomized, the distances from maize planting lines to the T. diversifolia hedge are ...
According to Bittner (2015) he argued that in a bid to ensure good community relations, organizations expend shareholders money, cut down workers salaries, waste precious time which should be used for other profitable things. He calls it “a fundamentally subversive doctrine which offers insoluble practical problems”. While Nweke (2001:220) is of the view that compliance and non compliance with the idea of corporate philanthropy determine the measure of goodwill, cordiality and ...
The main focused of this study was to evaluate the adoption of improved rice production technologies among farmers in Kudan Local Government Area of Kaduna state. The specific objectives of the study are to: describe the socio-economic characteristics of rice farmers, identify the sources of information used by rice farmers, describe the level of adoption of improved rice production technologies, determine the factors that influence the adoption of improved rice ...
Abstract: Melon dehusking is often associated with lots of manual labour and stresses. In order to reduce the stress and boredom usually involved in manual dehusking of melon process, a melon dehusking and separation machine was designed, constructed and tested for operation as presented in this paper. The melon dehusking machine operates on the principle of attrition/friction as opposed to the use of an impact force in the dehusking chamber for shelling of melon seeds. This pr...
ABSTRACTThis project deals with the design and development of restaurant order meal system, in order to reduce the number of staff. In meal ordering project, you can request for any kind of food or drinks available in the restaurant which contains the menu embedded in each button. Microcontroller is the central processing unit CPU of this project and it also consists of Bluetooth it is said to be the main component used in this project. Microcontroller gets the coordinates from the Bluetooth ...
ABSTRACT Beneficial bacteria that colonize the root of plants and are capable of stimulating the growth of plants directly or indirectly are called plant-growth promoting rhizobacteria. The objective of this study was to isolate and characterize plant-growth promoting rhizobacteria from the rhizosphere of some selected vegetables collected at different locations in Ago-iwoye, Oru and Ijebu-Igbo in Ijebu-North local Government Area of Ogun state, using general microbiological and biochemical t...
AbstractThe project DESIGN AND CONSTRUCTION OF A 20-METRE DISTANCE REMOTELY CONTROLLED METAL DETECTOR is used for detecting metallic objects such as phones, bombs, and other metallic objects that are hidden from view. The design is based on the principle of the Resonant Frequency Oscillator (RFO) metal detectors in which oscillation is a function of parallel connection of an inductor and a capacitor operating in resonance. The project is divided into two ...
