1. On the representation of precipitation in high-resolution regional climate models
Sammanfattning : Weather and climate models applied with sufficiently fine mesh grids to enable a large part of atmospheric deep convection to be explicitly resolved have shown a significantly improved representation of local, short-duration and intense precipitation events compared to coarser scale models. In this thesis, two studies are presented aimed at exploring the dependence of horizontal resolution and of parameterization of convection on the simulation of precipitation. LÄS MER
2. Kilometer-scale climate modeling of precipitation in the Nordic region
Sammanfattning : Future changes in precipitation, in particular extremes, are among the most impact-relevant consequences of a warming climate driven by increases in atmospheric greenhouse gas concentrations. Still, climate model projections of future changes in regional and local precipitation remain uncertain. LÄS MER
3. Tunneling Based Electronic Devices
Sammanfattning : This thesis concerns different kinds of tunneling based devices all showing negative differential resistance. The thesis is divided in three parts, resonant tunneling transistors, Esaki diodes and coupled zero dimensional systems. LÄS MER
4. Insulin Resistance and Inflammation as Risk Factors for Congestive Heart Failure
Sammanfattning : Congestive heart failure (CHF) is a major cause of morbidity and mortality and the identification of modifiable risk factors is crucial in order to diminish suffering of this common disease. The primary aim of this thesis was to investigate novel metabolic risk factors for CHF, with a focus on insulin resistance and inflammation. LÄS MER
5. Mixture Effects of Environmental Contaminants
Sammanfattning : Chemical exposure in humans rarely consists of a single chemical. The everyday exposure is characterized by thousands of chemicals mainly present at low levels. Despite that fact, risk assessment of chemicals is carried out on a chemical-by-chemical basis although there is a consensus that this view is too simplistic. LÄS MER
