Fusarium contamination of maize has been shown to be a problem in Zambia. In this study it was decided to test for the presence of five toxins produced by Fusarium; Zearalenone, T-2 toxin, diacetoxyscirpenol (DAS), deoxynivalenol (DON) and nivalenol, in maize and maize products. This was the...

Diazapolyoxamacrobicyclic compounds form ex-ceptionally stable complexes in organic nonpolar solvents by enclosing certain cations in the tri-dimensional cavity. In the present work, by using hydrogen bonding properties of chloroform.Tetraoxa-1,10-diazabicyclo(8.5«5) eicosane(2.1.1),...

The plant ' ntutula ' ( AristolochIa petersiana klotz) native to Zambia has been used in Zambian folk-lore medicine as an abortifacient. This work presents the Physiological and Chemical studies on this plant.Preliminary experiments confirmed the abortifacient activity of A petersiana klotz in...

Boats are of economic importance in parts of Zambia because of their adaptability and that they can survive well during drought. Most goats found in Zambia are kept by peasant -farmers under simple village management. In this study, ten kids with ages ranging from 5.5 to 2(3 weeks and,...

The traditional high concentrating photovoltaic systems have proved to be expensive as they use high grade silicon solar cells, highly specular reflecting materials and require tracking arrangements which are equally expensive. The problem of un-even illumination creates heat-sinks which have not...

In Zambia, mining of minerals is concentrated in the Copperbelt province. This and other industries of the area has brought about environmental degradation through release of possible unwanted toxic substances. The purpose of this study was to obtain the concentration of heavy metal pollutants,...

Oligosaccharyltransferase (OST) is a membrane bound enzyme that catalyzes the transfer of an oligosaccharide to the asparagine residue in the sequon, Asn-X-Thr/Ser. Eukaryotic OST protein complex consists eight non identical subunits, and among them STT3 possesses the transferase activity. The...

The production of energy from fossil fuels and nuclear materials has environmental drawbacks. These drawbacks include the creation of nuclear waste and the pollution associated with fossil fuels which lead to global warming and climate change. It is apparent that alternative and sustainable...
