1. Study of Porosity in Uncoated Cemented Carbide Tools During Titanium Alloy Machining.
University essay from Lunds universitet/Industriell ProduktionAbstract : During high speed machining of titanium alloys both the tool and workpiece material diffuse into one another affecting the surface integrity of the cutting tool edge and leading to fracture. One proposed mechanism by which the tool integrity is compromised results from the possible formation of porosity in to subsurface of the tool substrate close to the tool cutting edge. READ MORE

2. Three-dimensional modelling of the Källfallsgruvan iron oxide deposit, Riddarhyttan ore field, Bergslagen, Sweden: Integrating existing and new data to aid understanding of structural controls and mineral exploration
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : The Bergslagen ore province, located in the Fennoscandian shield in the south-central part of Sweden hosts several metallic mineral deposits, one of them being the Källfallsgruvan iron-oxide deposit in the Riddarhyttan ore field, situated in a high-strain shear belt denoted as the West Bergslagen Boundary Zone (WBBZ). An accurate 3D geological model of the Källfallsgruvan iron-oxide deposit has been generated to aid understanding of the ore body geometries and calculating volume and tonnage. READ MORE

3. Estimating active layer thickness at the high Arctic study site Zackenberg from remotely sensed ground subsidence
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : The active layer thickness (ALT) is an indicator of permafrost thaw, which potentially leads to the release of large amounts of greenhouse gases under global warming, and thus could further amplify climate change. The thaw depth of the active layer also governs seasonal surface deformation, caused by the volume change between ice to water, which poses risks for slope stability and infrastructure foundations.

4. Study and analysis of surface layer characteristics of lead brass and lead free brass
University essay from Högskolan i Halmstad/Maskinteknisk produktframtagning (MTEK)Abstract : The addition of lead to the copper alloys increase the machinability of thework material (without reference here to environmental factors) and reduces the overall production cost of the components at different stages, despite copper being expensive, which makes a challenging task to replace lead. Since lead is dangerous to human health. READ MORE

5. Magmatic Sheet Intrusions as Seen in Surface Deformation - Developing a Tool for Interpreting Volcanic Unrest
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : The end-member types of shallow magmatic intrusions comprise cone sheets and dykes. These propagate from their source magma chamber towards the Earth’s surface. The propagation of magma within the shallow part of the volcano plumbing system produces surface deformation and seismicity, signs of volcanic unrest. READ MORE
