1. 21. Oversampled radial basis function methods for solving partial differential equations

   Författare :Igor Tominec; Elisabeth Larsson; Bengt Fornberg; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; radial basis function; PDE; oversampling; stability; RBF-FD; RBF-PUM; unfitted;

   Sammanfattning : Partial differential equations (PDEs) describe complex real-world phenomena such as weather dynamics,  object deformations, financial trading prices, and fluid-structure interaction.  The solutions of PDEs are commonly used to enhance the understanding of these phenomena and also as leverage to make technological improvements to consumer products.

3. 22. Improved scientific basis for human health risk assessment factors by toxicokinetic population modeling

   Författare :Anna-Karin Mörk; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Exposure limits or guidelines are derived to protect humans from adverse effects caused by exposure to chemical substances in the environment or at the workplace. The internal dose of a chemical is determined by toxicokinetic (TK) processes such as uptake, distribution and elimination, and is closely related to the risk of adversity. LÄS MER

4. 23. Geophysical studies of the upper crust of the central Swedish Caledonides in relation to the COSC scientific drilling project

   Författare :Peter Hedin; Christopher Juhlin; Alireza Malehmir; Bjarne Almqvist; Charles Hurich; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; reflection seismic; collisional orogeny; Scandinavian Caledonides; COSC; scientific drilling; geophysical logging; gravity; magnetics; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

   Sammanfattning : The Collisional Orogeny in the Scandinavian Caledonides (COSC) project aims to provide a deeper understanding of mountain belt dynamics through scientific deep drilling in the central parts of the mountain belt of western Sweden. The main targets include a subduction related allochthon, the basal orogenic detachment and the underlying partially subducted Precambrian basement. LÄS MER

5. 24. Prehistoric human impact on wild mammalian populations in Scandinavia

   Författare :Hans Ahlgren; Kerstin Lidén; Anders Angerbjörn; Anders Götherström; Gørill Nilsen; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; hunter-gatherers; Baltic Sea; Mesolithic period; grey seal; harp seal; mountain hare; moose; ancient DNA; hunting; translocation; arkeologi med inriktning mot laborativ arkeologi; Scientific Archaeology;

   Sammanfattning : This thesis aims to study the interactions of pre-agricultural societies in Scandinavia with wild mammals, for example in terms of hunting and translocation. More specifically, the aim is to investigate the possibility of identifying examples of overexploitation, targeted hunting or translocation of wild mammals in prehistoric Scandinavia, and to discuss the implications this could have had for both the wild animals and the humans.

7. 25. Understanding the genetic basis of complex traits

   Författare :Yanjun Zan; Örjan Carlborg; Pär Ingvarsson; Uppsala universitet; []
   Nyckelord :genetic architecture; complex traits; epistasis; multi-allelic; genotype by environment interaction; polygenic adaptation; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

   Sammanfattning : Recent advances in genetics and genomics have provided numerous opportunities to study the genetic basis of complex traits. Nevertheless, dissecting the genetic basis of complex traits is still challenged by the complex genetic architecture, in which many genes are involved, and many have small contributions to phenotypic variation, interactions with other genes or environmental factors.
