Sammanfattning : Background: Iron (Fe) deficiency is globally the most common form of nutrient deficiency. The approach to combat this problem can be divided into two major strategies a): increasing the dietary Fe bioavailability by diet modification, or b): increasing the Fe intake through fortification.

Sammanfattning : The availability or iron from a meal is influenced by numerous factors. This thesis deals with three of them: organic acids, plant proteins (pea and soy), and transit time through the stomach and small intestine. LÄS MER
3. Casting Identities in Central Seclusion : Aspects of non-ferrous metalworking and society on Gotland in the Early Medieval Period
Sammanfattning : The aim of this thesis has been to investigate and interpret late Iron Ageand Early Medieval traces of non-ferrous metalworking on the islandGotland, Sweden. Gotland was not, based on the archaeological record, anintegrated part of the common Scandinavian culture. LÄS MER
Sammanfattning : The quantum chemical investigations presented in this thesis use hybrid density functional theory to shed light on the catalytic mechanisms of mononuclear non-heme iron oxygenases, accommodating a ferrous ion in their active sites. More specifically, the dioxygen activation process and the subsequent oxidative reactions in the following enzymes were studied: tetrahydrobiopterin-dependent hydroxylases, naphthalene 1,2-dioxygenase and α-ketoglutarate-dependent enzymes.
