21. Reflection seismic investigation in the Skellefte ore district : A basis for 3D/4D geological modeling
Sammanfattning : The Skellefte ore district in northern Sweden is a Palaeoproterozoic volcanic arc and one of the most important ones hosting volcanogenic massive sulfide (VMS) deposits, producing mainly base metals and orogenic gold deposits. Due to high metal prices and increased difficulties in finding shallow deposits, the exploration for and exploitation of mineral resources is quickly being moved to greater depths. LÄS MER
22. Melanogenesis as the basis for melanoma targeting
Sammanfattning : The incidence of malignant melanoma has increased rapidly during the last decades, and the prognosis for disseminated melanoma is poor. The melanoma cells produce melanin, and therefore the melanogenesis may serve as a target for treatment of melanotic melanoma; thioureyelenes such as thiourea and 2-thiouracil, e.g. LÄS MER
23. Establishing the mechanistic basis of sugar transport
Sammanfattning : Sugar is a vital molecule required for cell viability and homeostasis. Sugar is important for metabolic energy, energy storage, signaling, structure and osmolyte regulation. Transport of sugar represents an important physiological process. LÄS MER
24. The Cognitive Basis of Joint Probability Judgments : Processes, Ecology, and Adaption
Sammanfattning : When navigating an uncertain world, it is often necessary to judge the probability of a conjunction of events, that is, their joint probability. The subject of this thesis is how people infer joint probabilities from probabilities of individual events. LÄS MER
25. The genetic basis for adaptation in natural populations
Sammanfattning : Many previous studies in evolutionary genetics have been based on few model organisms that can be reared at ease in the laboratory. In contrast, genetic studies of non-model, natural populations are desirable as they provide a wider range of adaptive phenotypes throughout evolutionary timescales and allow a more realistic understanding of how natural selection drives adaptive evolution.
