  2. 1. The human diving response : effects of temperature and training

    Author : Erika Schagatay; Lunds universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Djurfysiologi; pig; human; training; breath-holding time; breaking point; cold-receptors; arterial blood; vasoconstriction; bradycardia; diving reflex; diving response; Breath-hold diving; Animal physiology; simulated diving; Organism biology; Organismbiologi; Sports; Idrott; Physiology; Fysiologi;

    Abstract : The aim was to elucidate the cardiovascular response associated with breath-hold diving, especially the effects of temperature in its elicitation and the effects of different types of training on the human diving response (DR) and breath-holding time (BHT), and to evaluate the human DR in a mammalian perspective. A model for simulated diving by apnea and facial immersion in cold water was developed. READ MORE

  4. 2. Further Investigations of Convergence Results for Homogenization Problems with Various Combinations of Scales

    Author : Tatiana Danielsson; Anders Holmbom; Liselott Flodén; Marianne Olsson Lindberg; Erika Schagatay; Peter Wall; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis is based on six papers. We study the homogenization of selected parabolic problems with one or more microscopic scales in space and time, respectively. READ MORE

  6. 4. Protective Responses to Freediving Reveal High-Altitude Tolerance

    Author : Pontus Holmström; Erika Schagatay; Angelica Lodin-Sundström; Harald K. Engan; Ola Eiken; Mittuniversitetet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acclimatization; Acute Mountain Sickness; Adaptation; Apnea; Breath-hold diving; Cardiovascular diving response; High-altitude; Hypoxia tolerance; Spleen; Acklimatisering; Andhållningsdykning; Anpassning; Apné; Kardiovaskulära dykresponsen; Hög höjd; Hypoxitolerans; Hög-höjdssjukdom; Mjälte; Syrebärande kapacitet;

    Abstract : High-altitude mountaineers - just as freedivers - are exposed to hypoxia. During freediving, the diving response leads to reduced oxygen consumption, and splenic contraction increases circulating hemoglobin concentration (Hb), which enhances freediving performance. READ MORE

  7. 5. Homogenization Results for Parabolic and Hyperbolic-Parabolic Problems and Further Results on Homogenization in Perforated Domains

    Author : Tatiana Lobkova; Anders Holmbom; Liselott Flodén; Marianne Olsson Lindberg; Erika Schagatay; Peter Wall; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis is based on four papers. The main focus is on homogenization of selected parabolic problems with time oscillations, and hyperbolic-parabolic problems without time oscillations. The approaches are prepared by means of certain methods, such as two-scale convergence, multiscale convergence and evolution multiscale convergence. READ MORE
