ABSTRACT Automatic water level controller circuit automatically switches ON and OFF a domestic water pump set depending on the tank water level. This motor driver circuit can be used at home, industry, school or even in agriculture. The approximated cost of the project is very less. The main advantage of this water level controller circuit is that it automatically controls the water pump without any user interaction. The main controller component is a NE 555 IC. We have manipulated the flip f...
ABSTRACT This work investigated the variation of top loss heat transfer coefficient with the emittance of the absorber plate, the collector tilt angle and air gap spacing between the absorber plate and the cover plate. The effects of the emittance of the absorber plate, the collector tilt angle and air gap spacing between the plate and the cover on the collector performance were also considered. Data collected from the thermosyphon solar water heater constructed by the National Centre for En...
ABSTRACT Sugarcane as an agricultural product is a readily available source of food for its sugar content. However, Sugarcane Bagasse Ash (SCBA) is the bi- product formed at sugar industries from the burning of sugarcane after the sugar content has been extracted. Sugarcane Bagasse Ash (SCBA) is a fibrous waste product containing mainly aluminum and silica, calcium ions to produce calcium aluminate hydrate (CAH) and calcium silicate hydrate (CSH) shown in the pozzolanic reaction below. Ca2+ +...
ABSTRACT This project involves the design and implementation of an intelligent obstacle-avoiding robot car. The objective of this project is to implement a robot car, which while moving should have the ability to detect obstacles in its path and change direction where obstacles are present without any form of external influence. The new direction to be taken to avoid collision is the direction that has the most distance between the obstacle and the sensor and this is determined by the robot b...
ABSTRACT When comparing with other manufacturing technologies, the extrusion technology always stands out as it is known to be highly efficient in terms of producing products of superior quality with the least possible amount of wastage. With the ever-increasing cost of materials, energy and the competition in the market, it becomes almost necessary to device a model with the minimum number of trials and shortest lead time. A multi-hole extrusion process was hence devised to serve the above n...
This research investigates the improvement of the mechanical and durability properties of concrete using Date Palm Seed Ash (DPSA) as partial replacement of cement. The DPSA used was obtained by controlled burning of date palm seed in a kiln at a maximum temperature of 630oc for eight hours and after cooling, it was sieved through 75um sieve and its oxide composition analysis was conducted using X-ray fluorescence (XRF) procedures. DoE method of mix design was used to produce concrete ingredi...
Wind energy is abundant, inexhaustible, affordable, environmentally preferable, and equally sustainable. More researches are emerging in the analysis of wind energy in Nigeria and each have proven that great potential exist for wind power generation in Nigeria but sufficient results is yet to be achieved in terms of application. The present research is intended to apply the technology of wind energy for pumping of water in rural Nigeria. To achieve this, a Savonius vertical axis wind turbine ...
Human necessities are increasing day by day where as the factories are running out of resources. To ameet these demands industries need to improve the quality and quantity of their production. Programmable logic controllers (PLCs) have been used for many decades for standard control in industrial and factory environments. Over the years, PLCs have become computational efficient and powerful, and a robust platform with applications beyond the standard control and factory automation. This pa...
The present study analyses the ongoing efforts to solve the fuel crisis of The Western India Plywoods Ltd (WIP), a large wood-based panel industry in Kerala via fuel briquettes from wood wastes generated from its own various manufacturing units with a well proven technique called biomass briquetting. Saw dust and other wood wastes and residues from all types of primary and secondary wood processing operations are generally bulky in nature and are therefore expensive to store and transport. Al...
This study aimed to evaluate the influence of organomineral fertilizer on the growth and mineral composition of Moringa oleifera organs. The experiment included three doses of cow dung, three doses of mineral fertilizers and two doses combining mineral fertilizers and cow dung. Soil samples and samples of M. oleifera organs were analyzed. Results revealed the contribution of fertilizer to improve soil chemical properties, except pH. The best vegetative development was obtained with the d...
Introduction to the background of the study: Maize (Zea mays) is the highest produced cereal crop and the most widely consumed food in Ghana with increasing production since 1965 (FAO, 2008; Morris et al., 1999). Maize is cultivated in all the ten regions of the country however the leading producing areas are mainly in the middle-southern part (Brong Ahafo, Eastern and Ashanti provinces) where 84 percent of the maize is grown, with the remaining 16 percent being grown in the northern region...
ABSTRACT The study was carried out at Nyankpala in the Northern region of Ghana from November 2012 to April 2013 to investigate the growth rate of Jatropha plant under two methods of propagation (seeds and cuttings) that best support the growth of the plant. Data on the survival rate, height and diameter were collected and other data were obtained through observation. Each of the plantation was divide into nine (9) plots and five plots were selected randomly for the studies. Each of the plant...
There is an inherent correlation between law and pace of infrastructural development. A solid, clear and foreseeable legal construction policy regime forms the basis for infrastructural development. In any form of legal regime, the role of the government and its bureaucracy remains crucial at every stage including licensing, construction and operation of infrastructural development projects. The Corona Virus (Covid-19) pandemic has introduced new construction requirements. This research work ...
In this paper, rocks with existing cracks and the effects on concrete structures it supports is discussed. Based on this paper, rock cracks may occur naturally when the rock gets closer to the earth surface due to erosion, through weathering processes (particularly frost wedging in mountainous areas and the diurnal heating and cooling of a rock outer layer in hot arid environments) and through tree roots. Artificially, cracks in rock may be caused by shock waves during rock blasting. The effe...
This study identified and correlated hydrocarbon bearing reservoirs, interpreted geological structures and petrophysical parameters and described facies and environment of deposition using seismic and well log data. These were with a view to assessing the impact of reservoir heterogeneity on petrophysical parameters and to determine the hydrocarbon potential of “Devo” Field, Niger Delta. Po...
