  1. 11. Studies of hyperandrogenicity and the metabolic syndrome in premenopausal women

    Författare :Fariba Baghaei; Göteborgs universitet; []
    Nyckelord :androgens; SHBG; HPA axis; abdominal obesity; insulin; HDL; metabolic syndrome; ovarian volume; PCOS; polymorphism; genetics; androgen receptor; estrogen receptor; aromatase;

    Sammanfattning : An androgenic sex hormone profile appears to be a typical feature of the metabolic syndrome (MetS) and a powerful risk factor for the development of type 2 diabetes in women. The causes of relative hyperandrogenicity (HA) are not clearly defined. LÄS MER

  3. 12. Breathing and phonation : effects of lung volume and breathing behaviour on voice function

    Författare :Jenny Iwarsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Abduction; Adduction; Breathing; Flow glottogram; Inhalation; Lung volume; Perceptual analysis; Phonation; Posture; Speech lung volume; Speech task; Subglottal pressure; Tracheal pull; Vertical laryngeal position; Vocal fold nodules; Voice source;

    Sammanfattning : Respiration is believed to play a central role in voice function and is thus of relevance to the clinical care of the disordered voice. The overall aim of the present study was to experimentally investigate relationships between the respiratory and phonatory systems. LÄS MER

  4. 13. Respiratory control in the newborn : central chemosensitivity, neuropeptides and nicotinic effects

    Författare :Ronny Wickström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Breathing is regulated by a complex network of neurons located mainly in the brainstem. For the newborn, it is critical for survival that a continuous respiration is established after birth. However, the regulation of respiration also undergoes maturation in the postnatal period.

  5. 14. Taper and volume equations for poplar trees growing on farmland in Sweden

    Författare :Birger Hjelm; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Effective management of poplar plantations for high yield production would be facilitated by the availability of improved equations for predicting the taper and volume of poplar stems. Therefore, this thesis is based upon a polynomial stem taper equation and two volume equations constructed for individual poplar trees growing on farmland. LÄS MER

  7. 15. The Alnö alkaline and carbonatitic complex, east central Sweden - a petrogenetic study

    Författare :Jaana Hode Vuorinen; Alasdair Skelton; Ulf Hålenius; Stefan Claesson; Ian Parsons; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbonatite; alkaline; Alnö; geochemistry; isotope; Earth sciences; Geovetenskap;

    Sammanfattning : The Alnö complex on the central Swedish east coast is composed of a main composite intrusion (the main intrusion) and four smaller satellite intrusions (Söråker, Sälskär, Långharsholmen and Båräng) distributed around the main intrusion on Alnö Island and on the mainland north of the island. The major rock types exposed within the complex are melilitolite, pyroxenite, ijolite series (melteigite-ijolite-urtite), nepheline syenite, carbonatite and alnöite dykes. LÄS MER
