1. Modern Computational Physical Chemistry : An Introduction to Biomolecular Radiation Damage and Phototoxicity
Sammanfattning : The realm of molecular physical chemistry ranges from the structure of matter and the fundamental atomic and molecular interactions to the macroscopic properties and processes arising from the average microscopic behaviour.Herein, the conventional electrodic problem is recast into the simpler molecular problem of finding the electrochemical, real chemical, and chemical potentials of the species involved in redox half-reactions.

2. Arctic clouds - interactions with radiation and thermodynamic structure
Sammanfattning : Clouds play in important role in the climate system through their interaction with radiation. Globally, clouds tend to cool the Earth by reflecting solar radiation and shading the surface. LÄS MER
3. Daphnids adaptive strategies to UV radiation
Sammanfattning : This thesis focuses on the adaptive strategies of daphnids that allows them to maintain stable populations while deal with UV radiation, highlighting the differences in the responses that populations with different evolutionary histories may have.Although exposition to lethal doses in nature is unlikely, sub-lethal UV-B radiation doses may have strong impacts on zooplankton.

4. Ultraviolet radiation and cornea
Sammanfattning : Background: Acute exposure of the mammalian eye to UVR results in development of photokeratitis after a period of a few hours. Chronic exposure to UVR is associated with an increased risk of several corneal disorders, including pterygium, climatic droplet keratopathy, and climatic proteoglycan stromal keratopathy. LÄS MER
5. Factors modifying cellular response to ionizing radiation
Sammanfattning : Many physical factors influence the biological effect of exposure to ionizing radiation, including radiation quality, dose rate and temperature. This thesis focuses on how these factors influence the outcome of exposure and the mechanisms behind the cellular response. LÄS MER
