1. Development of a geometallurgical framework for iron ores - A mineralogical approach to particle-based modeling
Sammanfattning : The demands for efficient utilization of ore bodies and proper risk management in the mining industry have resulted in a new cross-disciplinary subject called geometallurgy. Geometallurgy connects geological, mineral processing and subsequent downstream processing information together to provide a comprehensive model to be used in production planning and management.

2. Characterization and densification of carbonized lignocellulosic biomass
Sammanfattning : This thesis focuses on developing two main areas: characterization and densification of carbonized lignocellulosic biomass. Thermally treated biomass undergoes changes that enrich the content of carbon in the remaining solid fraction. LÄS MER
3. Identification and characterization of small molecules targeting MYC function
Sammanfattning : The MYC family genes (c-, N- and L-MYC) encode potent oncoproteins/transcription factors regulating fundamental cellular processes involved in cell proliferation, metabolism and survival, and they play an important role in tumor development. Overexpression of MYC often induce apoptosis as a failsafe mechanism to prevent tumor development and it is known to sensitize cells to genotoxic agents that induce DNA damage by triggered apoptosis.

4. Particle generation for geometallurgical process modeling
Sammanfattning : A geometallurgical model is the combination of a spatial model representing an ore deposit and a process model representing the comminution and concentration steps in beneficiation. The process model itself usually consists of several unit models. LÄS MER
5. Surface Integrity Characterization of Gears with respect to Running-in
Sammanfattning : A gearbox with gears of different sizes is part of a vehicle transmission system that plays an important part in transmitting the engine power to the wheels. The efficient energy transmission highly relies on the performance of gears. Together, the mesh efficiency and durability determines the gear performance. LÄS MER
