2. Studies of artificial mass bias in isotopic measurements by inductively coupled plasma mass spectrometry
Sammanfattning : Mass spectrometry, and especially inductively coupled plasma mass spectrometry (ICP-MS), suffers heavily from mass bias, or instrumental mass discrimination. The nett result of this effect is the preferential transmission, most often of heavier ions through the mass spectrometer. LÄS MER
3. On the Ising problem and some matrix operations
Sammanfattning : The first part of the dissertation concerns the Ising problem proposed to Ernst Ising by his supervisor Wilhelm Lenz in the early 20s. The Ising model, or perhaps more correctly the Lenz-Ising model, tries to capture the behaviour of phase transitions, i.e. how local rules of engagement can produce large scale behaviour. LÄS MER
4. Inflammation and prostate carcinogenesis : influence of immune characteristics and early-adulthood exposure to inflammatory conditions on prostate cancer risk
Sammanfattning : Chronic inflammation has been implicated in the development of several types of cancer, and evidence from observational and animal studies suggests that it may play a role also in prostate carcinogenesis. Recent observations have brought Cutibacterium acnes (C. acnes) forward as a possible causative agent in pro-oncogenic prostatic inflammation. LÄS MER

Sammanfattning : The kings of Norway issued coins on a regular basis starting in the mid-11th century, and probably conducted renovatio monetae whenever a new king came to power. As a privilege of bona regalia, the king could use coin production to serve his own interests. LÄS MER
