1. A Study on the Reaction between MgO Based Refractories and Slag-Towards the Development of Carbon-free Lining Material
Abstract : In present thesis, the fundamental studies on the reaction between MgO based refractories and slag were undertaken for the development of a carbon-free bonding MgO lining material. Alumina was selected as a potential binder material. Due to MgO-Al2O3 chemical reaction, the developed refractory was bonded by MgO·Al2O3 spinel phase. READ MORE

2. Treatment of arsenic contaminated drinking water from the sources around the gold mining areas of Geita and Mara, Tanzania : Removal efficiency of locally available materials, bauxite, gypsum and magnesite
Abstract : In recent years, high arsenic (As) levels of about 300 µg/L have been reported around the gold mining areas of Geita and Mara regions within the Lake Victoria basin (LVB) in Tanzania. During a sampling campaign at Geita and Mara, the groundwater and surface water samples revealed the presence of high As concentrations as well as Fe and sulfide. READ MORE

3. Electropermutation assisted by ion-exchange textile : removal of nitrate from drinking water
Abstract : Increased levels of nitrate in ground water have made many wells unsuitable as sources for drinking water. In this thesis an ion-exchang eassisted electromembrane process, suitable for nitrate removal, is investigated both theoretically and experimentally. READ MORE

4. A study of some aspects of gas-slag-metal interactions : Towards dynamic process model and control
Abstract : The present thesis deals with the development of a new type of dynamic model for metallurgical reactors. It also covers some of the theoretical aspects of steelmaking that is necessary to include in such an application. The thesis consists of modeling work, high temperature experiments and cold model experiments. READ MORE

5. Formation of non-metallic inclusions and the possibility of their removal during ingot casting
Abstract : The present study was carried out to investigate the formation and evolution of non-metallic inclusions during ingot casting. Emphasize have been on understanding the types of inclusions formed and developed through the casting process and on the development of already existing inclusions carried over from the ladle during casting.
