1. Studier av 2-cykloaminoindener speciellt med hänsyn till prototropa omlagringar
Sammanfattning : This thesis is a short review of six papers (Papers 1-6,page 5) concerning studies of enamines from 2-indanones. The unusually stable 2-(N-pyrrolidyl)indene has been studied (Paper 2 ). As a base catalyst this enamine rearranges 1-methylindene to 3-methylindene with a lower rate constant compared with triethylamine. LÄS MER
2. Bebyggelsenamnen i Bureå, Burträsks och Lövångers socknar i Skellefteå kommun jämte studier av huvudleder och nybyggesnamn
Sammanfattning : This thesis deals with place-names in the southern part of the municipality of Skellefteå in the province of Västerbotten, more precisely the parishes of Bureå, Burträsk and Lövånger. It consists of three different sections, first a survey of the settlement names in each parish, then a section on the second elements in these place-names, and finally a study of names of more recent settlements.

3. Prediction of wood species and pulp brightness from roundwood measurements
Sammanfattning : This thesis presents a number of studies, where a multivariate approach was taken to construct models that predict wood species and thermo mechanical pulp brightness from roundwood of Norway spruce and Scots pine. The first and second studies produced multivariate prediction models for wood species from the bark of spruce and pine. LÄS MER
4. Diabetes in 3D : β-cell mass assessments in disease models & evaluation of SPECT based imaging
Sammanfattning : Diabetes is a rapidly growing disease with 415 million affected adults worldwide. The pancreatic endocrine cells, most importantly the insulin producing β-cells, play an important role in regulating blood glucose homeostasis. LÄS MER
5. Innate Confinement Effects in PCL Oligomers as a Route to Confined Space Crystallisation
Sammanfattning : In this work, an in-depth analysis of crystalline characteristics has been performed for a unique set of strictly monodisperse poly-ε-caprolactone (PCL) oligomers. The molecules have different sets of end groups with various degrees of bulkiness and hydrogen bonding potential, affecting their aptitude to pack in ordered crystal structures. LÄS MER
