Abstract Rhizosphere studies of two local green vegetables, Celpsia argentea Linn and Hibiscus esculentus. Linn (new name Abelmoschus esculentus) were studied from vegetative stage to senescence. The viable seeds of both vegetables were collected and planted on garden beds made from sandy loam soil. Samples were collected at two-week intervals at 9.00 hrs in the the morning. Morphologically, A. esculentus (okra) had 3 leaves with more dense rooting system at 2 weeks than C.argentea (solo) wit...
Abstract This model was developed with close reference to the model used by Japan in their implementation of Mobile Suica a mobile wallet system which has served their transport woes since 2001 .The findings from this research showed that the previously proposed model for the adoption and acceptance of mobile technology, the TAM and the UTAUT can fully apply to the Zimbabwean economy with the additional of three more cons tructs which are political influence, economic influence and interopera...
ABSTRACT Sand gravity filters can be automated to suit your requirements. Be it industrial or domestic this model can be implemented with ease. This research is mainly focused on getting sand gravity filters in industries automated using measurable variables like flow and level. The controls are based mainly on monitoring the filter tank level versus the outlet and inlet flows. Inlet flow and outlet flow are regulated to maintain a certain level beyond which the filter tank will be deemed flo...

Abstract The laminar boundary layer flow in an exponentially stretching stenosed artery immersed in viscous and incompressible blood is investigated along with the effect of a chemical reaction. Many researchers have used mathematical modelling to predict blood flow through stenosed arteries. Pressure, shear stress and velocity are the parameters that have been analysed in the past. Not a lot of work has been done to highlight the effect of heat transfer on an exponentially stretching stenose...
ABSTRACT The interaction of landuse/Landcover (LULC) and climate change, to a large extent, involves anthropogenic activities. This interaction has brought about a complex global environmental change which includes biodiversity loss, land degradation, deforestation, afforestation and forest degradation among others. Such change is manifested through the dual nature of landuse/landcover both as causal factor and as effect of climate change. LULC is initiated through human activities such as fo...
