Application of optical methods to determine the concentration of sugar solutions
(2012-09-07)
Two optical methods were used to determine the concentration of sugar (sucrose) solution. The first employed a hollow perspex prism, a prism spectrometer and a monochromatic light source. The angles of minimum deviation ...
To find cost effective routes that are able to meet the fuel/time constraints using the Intelligent Transportation Systems in VANETS
(2012-08-29)
The use of real-time information in Intelligent Transportation Systems (ITS) in particular Vehicular Ad hoc Networks (VANETs) has the potential to improve traffic conditions and reduce travel delays by facilitating better ...
Optimisation of the growth conditions and genetic characterisation of Pleurotus species
(2012-08-29)
A comprehensive genetic and optimisation of the growth conditions study of fifteen Pleurotus species and strains from Belgian Coordinated Collections of Microrganisms/ Mycotheque de l’ Université Catholique de Louvain ...
Influence of elephant (Loxodonta africana Blumenbach) on Baikiaea plurijuga dominated woody vegetation around natural and artificial watering points in the northern part of Hwange National Park, Zimbabwe
(2012-08-29)
The extent of elephant damage on shrub and mature Baikiaea plurijuga was investigated around artificial and natural watering points in the Main Camp area of Hwange National Park. Damage was scored on a percentage basis for ...
Some apsects of products of totally permutable groups.
(2012-09-03)
In this work groups factorised as products of pairwise totally permutable subgroups are investigated in the framework of SC-groups, P ST -groups, PT -groups and T -groups. In particular an attempt is made to answer the ...
Asymptomatic Solution Of The Thin Shell Equations Containing A Turning Point
(2012-09-03)
The subject matter of this report is the vibrating behavior of thin shells of revolution when the generating line has a point of inflection at s*. At this point s*, the curvature changes its sign. We develop from the ...
A Study of Heap Fermentation and Protein Enrichment of Cassava.
(2012-08-30)
Cassava (Manihot esculenta Crantz) is an important source of carbohydrate for humans and animals, producing high energy of 610 kJ/100 g fresh root weight. However, it is very poor in protein (1 % fresh root weight) and ...
Atmospheric aerosol particles and transport: a climatological perspective for Zimbabwe
(2012-09-12)
Atmospheric aerosol particles were collected in the coarse (2-10 µm diameter) and fine (< 2 µm diameter) size fractions at Rukomechi research station, (16.1 °S, 29.4 °E, 500 m a.s.l.), northern Zimbabwe from September 1994 ...
The Macroinvertebrate Communities Of Two Upland Streams In Eastern Zimbabwe With Reference To The Impact Of Forestry
(2012-08-28)
Benthic macroinvertebrates and physico-chemical parameters of the water were examined from two fast flowing streams, the Nyahode River which drains a pine monoculture catchment and the Haruni River which drains an undisturbed ...
Modelling a low cost, data acquisition and irrigation sequencing system for a greenhouse on an 8 Bit PIC Microcontroller
(2012-08-29)
The debate on climate change is still going on and on, and there is still no convincing evidence that greenhouse gases are the real, real cause of the recent changes in climate patterns. Some records tend to suggest that ...
