1. Reward-related genes and alcohol dependence
Sammanfattning : Introduction: The rewarding properties of alcohol are mediated by the brain reward systems, specifically by the cholinergic-dopaminergic reward link, involving both nicotinic acetylcholine receptors (nAChRs) as well as the ghrelin signalling system. The susceptibility for developing alcohol dependence is influenced by genetic factors. LÄS MER
2. Ontogenetic scaling and the development of within-cohort size structure
Sammanfattning : It is increasingly recognized that individuals of the same species differ from each other and influence and respond to their environment in unique ways. This thesis deals with size variation among individuals that not only are of the same species but also of similar age. LÄS MER
3. Empirical Studies on Economic and Financial Spillovers : Asymmetric Risk and Dependence Modeling
Sammanfattning : Financial assets are volatile, and volatility becomes more intense in terms of size and rate of recurrence when markets are uncertain and growing rapidly. The fact that the recurrence rate increased during crisis periods, such as the IT bubble in the early 2000 and the global financial crisis that started in 2007, is a key finding in the literature.

4. Effects of size-dependent predation and competition on population and community dynamics
Sammanfattning : Most animals grow substantially during their lifetime and change in competitive ability, predatory capacity and their susceptibility to predation as they grow. This thesis addresses the implications of this on regulation and dynamics within populations as well as between population interactions. LÄS MER
5. Methods to Generate Size- and Composition Controlled Aerosol Nanoparticles
Sammanfattning : This thesis describes experiments performed using different methods to produce aerosol nanoparticles with control over size and composition. The process included differential mobility analyzers (DMAs) as size-selecting instruments and tube furnaces for particle synthesis. LÄS MER
