21. Sulphide mineral flotation : a new insight into oxidation mechanisms
Sammanfattning : Formation of hydrogen peroxide (H2O2), an oxidizing agent stronger than oxygen, by sulphide minerals during grinding was investigated. It was found that pyrite (FeS2), chalcopyrite (CuFeS2), sphalerite ((Zn,Fe)S), and galena (PbS), which are the most abundant sulphide minerals on Earth, generated H2O2 in pulp liquid during wet grinding in the presence or devoid of dissolved oxygen in water and also when the freshly ground solids are placed in water immediately after dry grinding.

22. Investigating Hydrogenous Behavior of Zintl Phases : Interstitial Hydrides, Polyanionic Hydrides, Complex Hydrides, Oxidative Decomposition
Sammanfattning : This thesis is an investigation into the hydrogenous behavior of Zintl phases. Zintl phases are comprised of an active metal (i.e alkali, alkaline earth, and rare earth) and a p-block element. The discussion gives an overview of the influence hydrogen affects the electronic and geometric structure of Zintl phases and subsequent properties. LÄS MER
23. Corporate Greening : Product and Production Perspectives
Sammanfattning : This thesis describes corporate greening in general, and specifically the environmental technology (ET) sector as a green sector. The thesis has also particular focus on production and products related aspects and the influence of the environmental profile of the ET sector on the environmental engagement of companies in the sector.

24. Optimal design for dose-finding studies
Sammanfattning : One of the most complex tasks during the clinical development of a new drug is to find a correct dose. Optimal experimental design has as a goal to find the best ways to perform an experiment considering the available resources and the statistical model. Optimal designs have already been used to determine the design of dose-finding studies. LÄS MER
25. Molluscs, Environment and Man - A Bioarchaeological Approach in Sweden
Sammanfattning : The thesis aims to examine the role and use of molluscs in Swedish prehistory, in chorological and chronological aspects. Molluscs live in the sea, fresh water and on land. The Swedish mollusc fauna contains 623 taxa: 417 marine, 85 limnic and 121 terrestrial species. LÄS MER
