(ISEM, 2011-09-23)This paper seeks to explore how Cleaner Production/Green Manufacturing can be used as a base for ISO 14001 certification in a tobacco processing environment. A framework is presented for how to implement ISO 14001 in a ... -
The Techno-Economic impact of Petrol- Ethanol Fuel blends on light duty vehicles: Case study- Zimbabwean Petrol Vehicle Fleet.
(2013-05-08)The Government of Zimbabwe has been promoting ethanol as a renewable, homegrown alternative vehicle fuel to gasoline. Ethanol is a form of alcohol that is combustible and can power engines easily. In Zimbabwe, it is made ... -
Elasto-Plastic collapse analysis of pipe bends using finite element analysis
(2014)When an external load is applied to one of its ends, a pipe’s bends cross section tends to deform significantly both in and out of its end plane. This shell type behaviour characteristic of pipe bends and mainly due to ... -
Design of a vehicle door structure based on finite element method.
(2014)The performance of door assembly is very significant for the vehicle design. In the present paper, the finite element method is used in the development processes of the door assembly. The stiffness, strength, modal ... -
Finite element analysis of ROM silo subjected to 5000 tons monotonic loads at an anonymous mine in Zimbabwe
(International Institute of Engineers, 2014-07)This paper introduces finite element analysis of Run off Mine (ROM) silo subjected to dynamic loading. The proposed procedure is based on the use of theoretical equations to come up with pressure and forces1 exerted by ... -
Enhancement of Shelf-Life and Oxidative stability of Jatropha curcas Biodiesel in Zimbabwe
(2014-12)Biodiesel is an environment friendly liquid biofuel similar to petro-diesel in terms of fuel quality and combustion characteristics. Increasing environmental concerns, fast depleting petroleum reserves and agriculture based ... -
Design of a small scale cereal packaging machine suitable for developing countries
(2015)Many food shortages which are being encountered in developing countries are due to lack of effective packaging which results in food loss. Packaging machines manufactured in developed countries are highly automated which ... -
