Process-based modelling of N losses from terrestrial ecosystems
(2010-05-20)
Nitrogen (N) loss to atmosphere and ground water can contribute to environmental destruction, by N emission as the greenhouse gas nitrous oxide (N2O) and by leaching of N to contamination and eutrophication of water. Dynamic ...
Towards a relativistically covariant many-body perturbation theory - With numerical implementation to helium-like ions
(2010-03-30)
The experimental results for simple atomic systems have become more and more accurate and in order to keep up with the experimental achievements the theoretical procedures have to be refined. Recent accurate experimental ...
General stress proteins: Novel function and signals for induction of stationary phase genes in E.coli
(2010-05-04)
Survival during conditions when nutrients become scarce requires adaptation and expression of genes for maintenance in order for the cell to survive. Among the numerous proteins involved in adaptation and regulation under ...
Ligand Dependent Regioselectivity in Palladium Mediated Allylic Alkylation
(2010-09-17)
In this thesis, different aspects on ligand dependent regioselectivity in palladium mediated allylic alkylation have been studied.
It is believed that the regioselectivity is a result of nucleophilic attack trans to ...
Environmental influences on the behavioural ecology of juvenile salmonids – the importance of rearing density
(2010-01-10)
Background and aims: Early environmental conditions are known to influence the phenotypic development of animals, including behavioural alterations. The overall aim of this thesis is to investigate the effects of density, ...
Taxonomy and phylogeny of polychaetes
(2010-05-03)
Polychaetes are a large group of segmented worms that display an enormous morphological diversity. Molecular data has shown in recent years that groups previously thought to be separate from polychaetes are actually part ...
Ionization of large molecules with short laser pulses
(2010-03-24)
The decay dynamics of fullerenes and polyaromatic hydrocarbons (PAH)
after femtosecond-laser excitation have been studied experimentally by electron
momentum mapping and mass spectrometry. The electron spectra of
fullerenes ...
On the ecophysiology of Baltic cyanobacteria focusing on bottom-up factors
(2010-11-05)
Cyanobacterial blooms in the Baltic Sea are dominated by diazotrophic cyanobacteria, i.e. Aphanizomenon sp. and Nodularia spumigena. The blooms coincide with a stable stratification and the organisms are concentrated to ...
In Silico Studies of Carbon Nanotubes and Metal Clusters
(2010)
Carbon nanotubes have been envisioned to become a very important material in various applications. This is due to the unique properties of carbon nanotubes which can be exploited in applications on length scales spanning ...
Egg size evolution and paternal care in pipefishes.
(2010-08-30)
In this thesis I explore how sexual selection, sexual conflicts, coevolution with parental care and an environmental selective agent (hypoxia) affect the evolution of different egg characteristics and embryo survival and ...
