The current climate crisis and human overpopulation demands more sustainable technologies for industrial chemical synthesis, such as biorefineries. The aim of this project was to study the potential of two non-model microorganisms to produce industrially ...

Visual attention has traditionally been studied with single-target search tasks where observers look for a single target and make a response, then the search is over and the trial ends. These studies have furthered our knowledge of visual attention ...

Despite the avowed aims of Icelandic welfare policies to provide services in a family-centred manner, parents commonly express their experiences of fragmented services that are offered more on the terms of the service providers than the families. ...

The effectiveness of a drug treatment regimen relies on the efficient delivery to afflicted target areas. Drug delivery devices aim to achieve a sustained release and maintain a steady drug concentration level that falls within a therapeutic range. ...

This thesis describes the glacial history, glacier dynamics, sediments and landforms of the Drangajökull ice cap as well as the glacial history and dynamics of the eastern Vestfirðir peninsula in northwest Iceland from the Late Weichselian until present. ...

Diel activity, the partitioning of time between periods of activity and rest, gives insights into how organisms compete for resources in time. Some species show plasticity in the rate and timing of their activity, which enables to study associations ...

Krill are an important component of the Icelandic marine ecosystem. Given their important ecological niche, as conveyors of biological production between phytoplankton and higher trophic levels, fluctuations in krill abundance can have large impacts ...

This doctoral study focuses on educational leadership at the municipal level in Iceland. Firstly, it aims to understand how leadership practices are shaped by policies and governance at the national, municipal and school levels, within a global and ...
