Abstract Joshua Mqabuko Nkomo International Airport was established in 1959 then known as Bulawayo Airport. It is located in the second largest city of Zimbabwe, 25 km to the north of the City of Kings- Bulawayo. JM Nkomo Airport is the second largest airport in Zimbabwe and boasts of two runways which are 2,588 meters long by 45 metres wide and 1,347 metres by 30 metres wide capable of handling wide bodied aircraft such as the Boeing 767. The airport operates 24 hours a day and is equip...
ABSTRACT The traffic situation at many university campuses in developing countries has been a source of concern to both the school authority and the campus populace. This may be largely due to the increasing enrolment level for university admissions since most employers are certificate-biased instead of skill rewarding. The roads are often congested during the day thereby causing inconveniences to everyone. During the "peak period" when vehicular traffic is beyond what the road can contain co...
ABSTRACT The increasing demand for silver nanoparticles has led to the need for new superior methods of synthesis to be developed. In this study, the Allium Ascalonicum plant was used in the plant-mediated synthesis of silver nanoparticles. The phytochemicals of the plant were extracted using seven different solvents with a range of polarities and the methanol/water 50/50 solvent had the highest extraction yield of 63 %. The phytochemical tests showed that the plant is rich in phytochemicals ...
ABSTRACT A green approach was used in the synthesis of silver nanoparticles which is an easy, cheap, eco-friendly and a fast method in achieving stable silver nanoparticles over a long period of time. Plant leaves extract from Parinari Curatellifolia and Vangueria Infausta were used in the synthesis after optimizing different parameters (temperature, silver nitrate concentration and amount of extract. The optimum conditions achieved for the synthesis of silver nanoparticles (AgNPs) using Pari...
ABSTRACT Usage of ergonomically unsuitable classroom chairs and desks promotes bad posture while bad postures affect students’ learning, performance and health. Attention is rarely paid to ergonomic fitness of classroom chair and desk used by primary school pupils in Nigeria up till now. This study investigated classroom furniture status in the Staff School, University of Ibadan, Oyo State, Nigeria and developed an automated procedure for designing ergonomically suitable chair cum desk mode...
ABSTRACT An experimental study was undertaken to evaluate and compare the performances of a local barn and a platform, as storage structures for yam tubers (Dioscorea rotundata poir.) The criteria used for evaluation and comparison were the degree of weight loss during storage, tuber sprouting and rotting of yam tubers during a 17 week storage duration between March and Ju...
Abstract Simulation of reliable solutions of nonlinear engineering problems by means of stable numerical algorithms is a frequent and acceptable practice. This study focuses the development and investigation of Range-Kutta coefficients dependent stability polynomial for the second, third and fourth orders Runge-Kutta schemes. The development utilized matrix inversion operation procedure that involves determinant and cofactors computation of relevant matrix. The validation was made referencin...
ABSTRACT This study exploited the possibility of new fractal creation in order to increase drastically the stock number of handy fractal images through the combination of limited base symmetric attractors' codes. the randomized play of chaos game with the iterated function systems (IFS) comprising a finite set of contractive affine maps coupled with simple coordinate transformation and linear superposition provides a framework for the new fractal image creation.
Abstract The aim of home automation is to control home devices from a central control point. In this paper, I present the design and implementation of a low cost but yet flexible and secure internet based home automation system. Nowadays, Internet has spread worldwide and most of the internet connections use Ethernet as media for data transfer. In industries or in home appliances, most of the time we need to monitor and control different parameters using microcontrollers. The popularity of ho...

ABSTRACT The advent of technology has made life easier, smooth and smarter. Smart phones are being applied in all aspects of life, be it Medical field, Military, Aviation or Agriculture. Agriculture is one of the key drivers of Zimbabwe`s Economy. The majority of Zimbabweans venture into farming for both personal sustenance as well as sustenance of the nation as a whole. Small farming projects are being carried out in the backyards of urban areas. People have resorted to growing Potatoes, Bea...
ABSTRACT The pharmaceutical supply chain in Zimbabwe and abroad is wrought with unscrupulous traders who have flooded the medical market with illegal, tampered and falsely labelled counterfeit drugs. The risk posed by these products has proved to be fatal to patients in recent years; and this is only the beginning of the problem. The local generic pharmaceutical industry has been dealt a huge blow due to the open boarder trading and excessive importation of falsified medicines into the countr...
ABSTRACT Considering mobile wireless networks in Zimbabwe, most base station wireless antennas are positioned in a three sector sequence, which is always symmetric and rigid. NetOne Zimbabwe always maintains this setup while Econet takes a step further by conducting RF optimization and re-arrange the azimuth, the engineers and riggers travel to the site to make alterations and it becomes an extra unexpected expense to the company. This calls for the need to come up with an automatic system th...
ABSTRACT The toll collection system currently used in Zimbabwe is an open system whereby toll levies are collected manually by toll collectors at various tollgates across the country. This system has negative effects on both the drivers and passengers as it causes time delays and traffic congestion at tollgates especially during public holidays where traffic volumes are enormous as people will be travelling. The Tollgate Collection System using RFID Technology project will eliminate hard cash...
ABSTRACT Biological and antioxidant activities of Dicoma anomala, Kigelia pinnata, Pseudolachnostylis maprounelifolia and Flacourtia indica are reported. The medicinal plant extracts of different polarities were prepared and tested for antimicrobial activity using the disc diffusion method. The acetone crude extracts showed the highest activity as compared to the chloroform and petroleum ether extracts. The qualitative analysis of the extracts showed presence of tannins, saponins, phenolics, ...
