26. Försök till tefrokronologisk datering av sediment från övergången yngre dryas-preboreal genom korrelation med en tidigare studie
Kandidat-uppsats, Institutionen för naturgeografi och kvartärgeologi (INK)Sammanfattning : Syftet med denna studie var att försöka datera en sedimentstratigrafi genom att undersöka möjligheten till korrelation med resultaten från en tidigare studie via tefrokronologiska metoder. Tefrokronologi är studierna och metoderna där man identifierar och daterar tefra (vulkanaska) i lagerföljder för att användas som ett synkroniseringsverktyg mellan olika sedimentstratigrafier.

27. Analysis of Lining Properties at Landfills Using Geophysical Methods - Case Study: Tveta (Sweden).
Master-uppsats, KTH/Teknisk geologi och geofysikSammanfattning : Recently established EU environmental legislation obliged Sweden to close many landfills until year 2020. Such an operation requires a lot of inexpensive and water resistant coverage materials. Six prototypes of linings were constructed at Tveta landfill. LÄS MER
28. Reduction of Fine Particle and Deposit Forming Alkali by Co-Combustion of Peat With Wood Pellets in 150 kWth Grate Firing Boiler
Master-uppsats,Sammanfattning : The objective of the present work was to demonstrate the possibilities to reduce the emission of fine particle forming alkali during co-combustion of wood with peat in a full scale (150 kW) grate fired boiler. For this purpose the particle emissions from a 150 kW district heating grate fired boiler situated in northern part of Kramfors, Sweden, were studied. LÄS MER
29. Extraterrestrisk och terrestrisk kromrik spinell i fanerozoiska kondenserade sediment
Magister-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : This study aims to assess the normal inflow of extraterrestrial chromite to Earth. The results from the investigation are compared to earlier studies of middle Ordovician Orthoceratite Limestone in which 1 - 3 extraterrestrial chromite grains ( >63 ƒÊm ) per kilogram limestone were found.

30. Environmental Systems Analysis for utilisation of bottom ash in ground constructions
Master-uppsats, KTH/Industriell ekologiSammanfattning : To decrease the disposal of waste and to save natural resources, several political initiatives have been initiated both in Sweden and at a European level. Therefore an urgent task is to find suitable utilisation areas for residuals, such as construction materials. LÄS MER
