1. Pyrolysis of Municipal Sewage Sludge to get a phosphorus rich char residue for soil improvement
Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : Sewage sludge is a byproduct of wastewater treatment plants. It is a kind of waste. however, it contains several valuable nutrients like phosphorous and nitrogen that are used to rich the soil as a fertilizer compound. LÄS MER
2. Theoretical investigation of Co-dependence in magnetic high-entropy alloys
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : High-entropy alloys (HEA) is a class of materials consisting of multiple principal elements that often crystallize in simple lattices such as body-centered cubic, face-centered cubic and hexagonal close-packed structures. Many HEAsexhibit exceptional mechanical properties, e.g. LÄS MER
3. Evaluation of long-term effects of excavated sulfide-bearing rock : - A case study in western Sweden
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : Sulfide-bearing rock that is excavated in conjunction with construction projects can cause environmental and construction engineering problems. Sulfidic minerals oxidize when they are exposed to an oxidant and water, which can make them generate acid rock drainage (ARD) with high concentrations of metals and sulphate. LÄS MER
4. Acid sulphate soils and its influence on metal concentrations in adjacent water bodies. - A case study from Halland, SW Sweden
Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaperSammanfattning : Acid sulphate soils have been referred to as being among the most harmful soils in the world due to their ability to severely decrease the pH of the water, consequently enabling an increased metal load to recipient water streams, lakes, groundwater reservoirs and estuaries. The presence of acid sulphate soils has triggered several fish kill episodes in northern Scandinavia and the soils are today threatening many of the national environmental goals of Sweden. LÄS MER
5. Shear Strength between a Resin Cement and a Cobalt-Chromium Alloy and Yttria-Stabilized Zirconia
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för odontologiSammanfattning : New trademarks appear on the dental market every year and it is difficult to determine whether they should be used in clinical praxis or not. Numerous studies have been carried out to investigate different types of materials, trying to declare which material is best suited for a certain type of restorations. LÄS MER
