  2. 2. Studies of artificial mass bias in isotopic measurements by inductively coupled plasma mass spectrometry

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Henrik Andrén; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : 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. READ MORE

  3. 3. On the Ising problem and some matrix operations

    University dissertation from Umeå : Matematik och matematisk statistik

    Author : Daniel Andrén; Roland Häggkvist; Henrik Eriksson; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ising problem; phase tansition; matrix multiplicatoin; matrix inversion; MATHEMATICS Algebra; geometry and mathematical analysis Discrete mathematics; MATEMATIK Algebra; geometri och analys Diskret matematik;

    Abstract : 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. READ MORE

  4. 4. Inflammation and prostate carcinogenesis : influence of immune characteristics and early-adulthood exposure to inflammatory conditions on prostate cancer risk

    University dissertation from Örebro : Örebro University

    Author : Henrik Ugge; Katja Fall; Sabina Davidsson; Jessica Carlsson; Ove Andrén; Lars Henningsohn; [2019]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; inflammation; Cutibacterium acnes; acne; appendicitis; cytokines; circulating; inflammation marker; IL6; CXCL8;

    Abstract : 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. READ MORE
