  1. 1. Testosterone Analysis in Hair

    Författare :Julia Preinbergs; Jakob Ström; Elvar Theodorsson; Edvin Ingberg; Ulrik Kvist; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The effects of testosterone in the body are dependent on the concentrations at the target organs, as well as the susceptibility of the androgen receptor. Steroid hormones circulate in the bloodstream bound to proteins, and only a small part is unbound and free to exert its effect at the receptors. LÄS MER

  3. 2. Strong Cosmic Censorship and Cosmic No-Hair in spacetimes with symmetries

    Författare :Katharina Maria Radermacher; Hans Ringström; James Isenberg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cosmic Censorship; Cosmic No-Hair; Big Bang; symmetry; Bianchi; T2-symmetry; Gowdy; general relativity; cosmology; late time; initial time; asymptotic behaviour; perfect fluid; scalar field; Einstein equations; Mathematics; Matematik;

    Sammanfattning : This thesis consists of three articles investigating the asymptotic behaviour of cosmological spacetimes with symmetries arising in Mathematical General Relativity.In Paper A and B, we consider spacetimes with Bianchi symmetry and where the matter model is that of a perfect fluid.

  4. 3. Trace Element Analysis with Application to Environmental Pollutants Studies in Vietnam

    Författare :Thi Hong Nguyen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; blood; environmental samples; discriminant analysis; ICP-MS; coal mining; hair; EDXRF; microwave digestion; CV-AAS; urine; sample preparation; coal combustion;

    Sammanfattning : In the work presented here the attention has been focused on optimising sample preparation and analytical techniques for trace element determination, analytical quality assurance and environmental applications. Trace element concentrations in various environmental matrices were investigated using Energy Dispersive X-ray Fluorescence (EDXRF), Inductively Coupled Plasma Mass Spectro-metry (ICP-MS) and Cold Vapour Atomic Absorption Spectrometry (CV-AAS).

  5. 4. Analysis of domestic dog mitochondrial DNA sequence variation for forensic investigations

    Författare :Helen Angleby; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; forensics; mtDNA; control region; hair; domestic dog; breed; Bioteknik; Bioengineering; Bioteknik;

    Sammanfattning : The first method for DNA analysis in forensics was presented in 1985. Since then, the introduction of the polymerase chain reaction (PCR) has rendered possible the analysis of small amounts of DNA and automated sequencing and fragment analysis techniques have facilitated the analyses.
