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),...

Access to reliable and affordable energy is an essential input to sustainable development. Most of the rural communities in Zambia lack access to modern energy. Renewable energy technologies offer a solution to this. Through the help of various stakeholders, various renewable energy technologies...

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,...

Disputes in the construction industry are often inevitable. Disputes arise from the interpretation and application of any part of ambiguous, unplanned and conflicting contract documents. There are many methods which can be used to resolve disputes. The study in this dissertation examined the...

Availability of data and information on groundwater is important for sustainable utilization of groundwater resources. Its assessment, development, utilization and management largely depend on data acquisition; the aspect often overlooked or inconsistently carried out in most groundwater...

This study is about an ethical evaluation of deforestation in Mwekera National Forest No. 6. The objectives of the study were: to investigate why deforestation is still going on in the Mwekera National Forest No. 6 even though the Forest Policy and Forest Act are in force; to investigate to what...

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...

A lot of research in ecotoxicology is currently focused on identifying and developing suitable biomarkers for use in assessing environmental pollution. Thus this study was aimed at assessing the potential of Cytochrome P450 1A1 (CYP 1A1), Cytochrome P450 3A (CYP 3A) and Metallothionein1 (MT 1) as...

The use of backfill in underground mines has increasingly become an integral part of overall mining operations all over the world. This has largely been driven by the need to increase ore recovery and productivity. The underground mining activities have given rise to creation of large volumes of...
