  1. 1. Estimation of Speaker Age : Effects of Speech Properties and Speech Material

    Författare :Sara Skoog Waller; Mårten Eriksson; Billy Jansson; Mittuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Age estimation; Voice perception; Speech properties; Speech rate; Vocal disguise; Age disguise; Accuracy; Confidence; Spontaneous speech;

    Sammanfattning : The aim of this thesis was to investigate factors related to accuracy in estimation of speaker age and the role of certain speech properties in perception and manipulation of speaker age, as well as their interaction with the speech material that the age estimates were based on. This thesis consists of three studies. LÄS MER

  2. 2. Adverse effects of psychotropic drugs in old age

    Författare :Jon Brännström; Hugo Lövheim; Yngve Gustafson; Peter Nordström; Patrik Midlöv; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Geriatric medicine; psychotropic drugs; adverse effects; mortality; hip fracture; cohort study; old age; Geriatrics; geriatrik;

    Sammanfattning : Background: With increasing age, the body and mind transform. Many of our organs gradually lose capacity, making them more sensitive to the effects of several drugs. In parallel, many of us accumulate an increasing burden of disease and other conditions warranting the use of medications. LÄS MER

  3. 3. The age of transported scalars in fluid mechanics

    Författare :Federico Ghirelli; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; grate furnace; velocity correlation; fluid age; scalar age; turbulence model; residence time; energy spectrum; turbulence age;

    Sammanfattning : Computational fluid dynamics (CFD) is applied to the reacting flow in the freeboard of a 30MW biofuel fired grate furnace and results are validated by comparison with data from an extensive measurement campaign. The influence of the fuel bed model on the results of the freeboard model is investigated. LÄS MER

  4. 4. GABA-steroid effects in healthy subjects and women with polycystic ovary syndrome

    Författare :Helena Hedström; Torbjörn Bäckström; Marie Bixo; Ian Milsom; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Allopregnanolone; isoallopregnanolone; gonadotropins; GABA-A receptor; women; polycystic ovary syndrome; saccade; obstetrik och gynekologi; Obstetrics and Gynaecology;

    Sammanfattning : Background: The progesterone metabolite allopregnanolone is involved in several clinical conditions in women, e.g. premenstrual dysphoric disorder. It is a very potent GABA-steroid with GABA-A receptor effects similar to other GABA-agonists, e. LÄS MER

  5. 5. Long QT syndrome in Sweden : founder effects and associated cardiac phenotypes

    Författare :Annika Winbo; Annika Rydberg; Eric Schulze-Bahr; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Long QT Syndrome; Jervell and Lange-Nielsen Syndrome; inherited arrhythmia; founder effects; clinical genetics; haplotype analysis; mutation age; founder mutation; clinical phenotype; life-threatening cardiac events; mutation-specific; KCNQ1 gene; modifier genes; sequence variants; risk stratification; risk factor; gender; pediatrik; Pediatrics;

    Sammanfattning : Background: We aimed to increase the knowledge regarding the familial arrhythmogenic disorder Long QT Syndrome (LQTS) and its recessive variant Jervell and Lange-Nielsen Syndrome (JLNS) in Sweden, including prevalences and clinical phenotypes. A specific focus was directed towards two KCNQ1 mutations –p.Y111C and p. LÄS MER
