1. Dispersal, inbreeding and fitness in natural populations
Sammanfattning : To evaluate how inbreeding affects the viability of small populations, it is crucial to determine what constitutes a population (i.e., the number of breeders in local patches and the degree of dispersal), and also to estimate the reproductive consequences of philopatry and emigration.

2. Slakt i takt : Klassformering vid de bondekooperativa slakterierna i Skåne 1908-1946
Sammanfattning : From the begiining of the 20th century producer co-operative bacon factories were established in the south of Sweden. In his thesis Lars Hansson studies how class relations were shaped and transformed within this rural industry. LÄS MER
3. First determination of the electric charge of the top quark
Sammanfattning : In this thesis, the first determination of the electric charge of the top quark is presented using 370pb-1 of data recorded by the DØ detector at the Fermilab Tevatron accelerator. ttbar events are selected with one isolated electron or muon and at least four jets out of which two are b-tagged by reconstruction of a secondary decay vertex (SVT).

Sammanfattning : This thesis studies teachers’ and students’ conceptions of history and history teaching and aims to explain the importance of an interest in history among teachers and students of the subject. Research on teachers’ conceptions (e.g. LÄS MER
5. First Determination of the Electric Charge of the Top Quark and Studies of the Top Quark Pair Background to New Physics
Sammanfattning : This thesis is concerned with experimental investigations of properties of the top quark and processes involving this particle. In the first part of the thesis, the first determination of the electric charge of the top quark is presented. LÄS MER
