A method for the determination of polycyclic aromatic hydrocarbons (PAH) in carbonaceous materials and on particulate Batter produced in the atmosphere during the electrolytic reduction by various methods in the metallurgical ...
Essential oil composition and some biological activities of tetradenia riparia

Khuzwayo, Joyce Khethiwe (University of Zululand, 2011)

This dissertation has a brief historical overview of medicinal plants, T. riparia and their traditional uses. The choice of the medicinal plant studied was based on the evidence in literature that oils of the species contain ...
Establishment of the relationship between the sediments mineral composition and groundwater quality of the primary aquifers in the Maputaland coastal plain

Mkhwanazi, Millicent N. (2010)

The Maputaland coastal plain has the largest primary aquifers in South Africa. It has highly permeable sediments that promote rapid recharge to the aquifers and strong interactions with wetlands in the region. The ...
Extraction of cellulose from SCB and its applications in CNC/metal nanocomposites

Mzimela, Zimele N.T. (University of Zululand, 2018)

The past few years have seen an increased interest in enforcing the principles of green chemistry in the scientific community. The aim of these principles is to reduce chemical related impacts on human health and virtually ...
