According to the Sustainable Development Goals (SDG) ‘s indicator baseline 2017 report of South Africa, the percentage of the population using safely managed drinking water services has remained more or less constant around 91% between 2014 and 2016. The observation of the same variable from 1996 to 2011, shows a significant increase from 76.6% to 89.4%. This therefore means between 2011 and 2016, the change has been insignificant. To have a sample analysis in this regard, on the dynamics...
Abstract The ‘City Logistics’ activities are contributing to traffic congestion and accumulating to environmental challenges, such situation has prompted the creation of urban consolidation centre (UCC), as a multimodal logistics park facility in the outskirts. The relocation of business from city to the outskirts requires the evaluation and assessment of the key factors in order to make the better decisions. However, no relocation decisions evaluation model has been found, neither its ap...
ABSTRACT. Routing protocol has taken some vital roles in this modern internet era. Routing protocol determines how routers communicates with each other to enable the forwarding of packets that takes place through the use of optimal path which enables transmission from one source node to the destination node. In this study work, the exploration of the important protocols, namely; Enhanced Interior Gateway Routing Protocol (EIGRP), Open Short Path First protocol (OSPF), Routing Information Prot...
ABSTRACT Moringa oleifera grows in the tropical and subtropical regions of the world. It is commonly known as ‘drumstick tree’ or ‘horseradish tree’ in Nigeria. Moringa can withstand both severe drought and mild frost conditions and hence widely cultivated across the world. With its high therapeutic values, every part of the tree is suitable for either nutritional or commercial purposes. The leaves are rich in minerals, vitamins and other essential phytochemicals. Extracts from the le...
ABSTRACT Maize, known in many English-speaking countries as corn, is a grain domesticated by indigenous people in prehistoric times. The Aztecs and Mayans cultivated it in numerous varieties throughout central and southern Mexico, to cook or grind in a process called nixtamalization. The crop spread throughout America and later around the 1250 BC it spread to all corners of the region. Any significant or dense populations in the region developed a great trade network based on surplus and var...
Some inventions are glamorous and very sophisticated – microchips embedded system technology –and more while some others are quieter, yet not less relevant in easing the work that man has to do with his own energy. Pumps do fall in the latter category (Mario, 2001). This project is intended to model a portable solar powered suction pump. Pumps are devices that transfer fluids (liquid or gas) from one point to another through some mechanical means. Pumps generally have being in use for cen...
This project is based on the design and construction of a Wireless Electronic Notice Board. It can be widely used to display latest information anywhere such as institutions, shop, place of worship and other places. This Wireless Electronic Notice Board will offer flexibility to user to control the information display within 50m to 200m range. Similar works were reviewed and the draw backs of these projects were cited and their advantage also considered. The design of the Wireless Elec...
Solar powered systems have been built for various applications ranging from public lighting to water supply units but robust efforts have not been made in the development of pumping systems that can effectively replace the manually operated pumps used in field applications. Designing a machine that can pump the fluid without the need of so much energy on the part of the operator as well as boycott the use of direct electricity will hence be a reasonable contribution to field of maintenance an...
ABSTRACT Breadfruit (Treculia Africana) or simply breadnut is very important both as food and as a potential source of oil. The economic importance of this tropical seed on domestic and commercial basis has necessitated the development of a pedal breadfruit dehuller, that would reduce the Cost of maintaining and purchasing motorized dehuller, Solve the problem of fuel scarcity, inadequate electricity supply . In the engineering design of this machine, the action zone consisted esse...
This project work aims at formulating Scheffe’s mathematical model which prescribes concrete mix ratios for a desired compressive strength of periwinkle shell aggregate concrete and obtaining the combination of water, cement, river sand and periwinkle shell which will produce the optimum strength.The model was formulated from first principle producing an equation with several unknown coefficients. These coefficients were determined by carrying out compressive strength test on thirty c...
Abstract This research work examined the role of informal Sector in employment generation in Ilorin, kwara state Nigeria. The study made use of primary data obtained from 100 respondents from Ilorin West Local Government in kwara state through the copies of questionnaire administered. The data collected was analysed using descriptive statistics and statistical package for social sciences (SPSS). The outcome of the empirical investigations showed th...

ABSTRACT The objective of the work is the catalytic conversion of waste plastics into fuel oil and solid wax using Ca(OH)2 and the design of pyrolysis reactor. Plastic wastes such as, polypropylene, low density polyethylene, high density polyethylene, polystyrene are the most frequently used in everyday activities and disposed of to the environment after service. There are a number of methods by which plastic wastes can be managed such as incineration, recycling, land filling, thermal and cat...
This paper discusses the recent investigation into the composite action of pultruded Fibre Reinforced Polymer (FRP) and concrete hybrid systems, under static push-out tests. The study sought to experimentally determine the characteristic load-slip behaviour of the FRP-concrete composites under varying shear stud arrangements and failures modes associated with the variations and the push-out load capacity. For the initial tests, three composite test specimens were fabricated using FRP wide fla...
