The Interplay Between Selection And Constraints On Adaptive Divergence And Phenotypic Evolution

Under natural or sexual selection, individuals with advantageous traits or combinations of traits will be more successful than their peers at surviving and/or reproducing. Provided these traits are heritable, meaning that they have a genetic basis, the traits combinations which are selected for, will increase in frequency in the population. When selection is intense and persistent, adaptive traits

Speglingar av Småland

Varför är Småland ett landskap som fascinerar? Kanske för att det är så mångsidigt och omväxlande, likt en brokig mosaik. Dess historia är rik och man har aldrig kunnat tala om ett Småland eller en småländsk identitet. I denna antologi möts tio forskare kring frågan avd som egentligen är småländskt. Läsaren tas med till Astrid Lindgrens Värld och till det småländska Glasriket. De möte tyska och da

Quantum chemical characterization of oxide nanoparticles and interactions on their surfaces

Popular Abstract in English Nanotechnology is a quickly developing field, which applies objects of extremely small sizes to novel technological applications. These objects, so-called nanomaterials, have at least one dimension measured in nanometers, 10-9 meters. Nanoparticles are of interest to chemists due to their distinct properties, which differ significantly from the bulk material. This uniquTitanium dioxide and related oxide materials have been investigated using density functional theory calculations. Nanocrystalline particles were modelled by a finite cluster approach. The studies focus on the characterization of structural and electronic properties of TiO2 and related group-IV materials (SiO2, GeO2, SnO2), as well as, interactions on their surfaces. A set of bare cluster models o

Parents' travel mode choice for their children's leisure journeys - role of trust.

Many parents perceive the urban environment as hazardous for their children and therefore prescribe and circumscribe young people’s access to the environment (Malone, 2001). Consequently, spontaneous unregulated play in neighbourhood spaces is decreasing as children are primarily encouraged to participate in regulated play environments in their homes, friends houses and commercial facilities.
