6. Diurnal variation of stratospheric short-lived species
Sammanfattning : Diurnal variation of stratospheric short-lived speciesMaryam KhosraviChalmers University of TechnologyDepartment of Earth and Space SciencesAbstractThe depletion of ozone in the stratosphere has a direct impact on the amount of ultravioletradiation reaching the Earth’s surface. The ozone abundance and distributionis controlled by the photo-chemical reactions and catalytic cycles involving halogens(chlorine and bromine), odd hydrogen and odd nitrogen species as well as by atmospherictransport.

7. On the analytical engagement of social semiotics and variation theory in physics education research
Sammanfattning : In this licentiate thesis, I explore how two theoretical frameworks—social semiotics and the variation theory of learning—used in physics education research, can be fruitfully combined to obtain additional analytical tools for analysing student learning in introductory level university physics. Each theoretical framework has on their own, or together with other frameworks, been successfully applied for analysing both individual and collective learning, but the combination of the two has yet not been fully explored.

8. On Neuromagnetic Assessment of the Contingent Negative Variation
Sammanfattning : The contingent negative variation, CNV, is a cognitive process related to anticipation and motor preparation. In the present work the CNV was studied by the use of magnetoencephalography, MEG. LÄS MER
9. The Progressive in 19th-Century English : A Process of Integration
Sammanfattning : The present work is a corpus-based study of the English progressive during the 19th century. The study is based on Conce, a one-million-word corpus covering the period 1800–1900 and comprising seven genres, both speech-related and non-speech-related. LÄS MER
10. Two Optimization Problems in Genetics : Multi-dimensional QTL Analysis and Haplotype Inference
Sammanfattning : The existence of new technologies, implemented in efficient platforms and workflows has made massive genotyping available to all fields of biology and medicine. Genetic analyses are no longer dominated by experimental work in laboratories, but rather the interpretation of the resulting data. LÄS MER
