  2. 1. Perinatal Risk Factors for Childhood Leukemia

    Author : Estelle Naumburg; Eleni Petridou; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrics and gynaecology; Childhood leukemia; infant leukemia; leukemia epidemiology; supplementary oxygen; perinatal risk factors; perinatal infection; prenatal ultrasound; prenatal x-ray; Obstetrik och kvinnosjukdomar; Obstetrics and women s diseases; Obstetrik och kvinnosjukdomar; pediatrik; Pediatrics;

    Abstract : The aim of the studies described in this thesis was to assess the association between certain perinatal factors and the risk of childhood lymphatic and myeloid leukemia and infant leukemia. The five studies presented were all conducted in Sweden as population-based case-control studies. READ MORE

  4. 2. Mechanisms and genes controlling the signalling network for biotic and abiotic stress defences in Arabidopsis thaliana (L.) Heyhn : Functional cross-talk between photo-produced reactive oxygen species, photosynthesis and plant disease defence responses

    Author : Christine Chi-Chen Chang; Stanislaw Karpinski; Christine Foyer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; reactive oxygen species; Arabidopsis thaliana; signalling work; biotic stress; abiotic stress; Plant physiology; Växtfysiologi;

    Abstract : Excess excitation energy, mechanical injury and defence against pathogens, each trigger rapid production of reactive oxygen species (ROS) in Arabidopsis thaliana leaves. ROS, such as hydrogen peroxide (H2O2), are required for the induction of systemic acquired acclimation and may lead to redox changes in photosynthetic electron transport (PET). READ MORE

  5. 3. Physiological effects of apnoeic oxygenation using high-flow nasal oxygen

    Author : Ida-Maria Forsberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : In anaesthetic practice, the inability to oxygenate and ventilate patients is a much-feared complication with risk for severe hypoxia-induced adverse outcomes. By administrating oxygen in the absence of spontaneous ventilation, apnoeic oxygenation may overcome these challenges by a prolonged time with sufficient oxygenation. READ MORE

  6. 4. Physiological and biomechanical aspects of rifle carriage during biathlon skiing

    Author : Malin Jonsson Kårström; Marko Laaksonen; Kerry McGawley; Guillaume Millet; Mittuniversitetet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3D-measurement; anaerobic energy contribution; crosscountry skiing; kinematics; lactate threshold; load carriage; oxygen uptake; performance; sex differences; sub-techniques; training;

    Abstract : Biathlon is an endurance-based winter sport that combines crosscountry (XC) skiing with rifle marksmanship. While skiing, biathletes carry the rifle (weighing ≥ 3.5 kg) on their backs. However, research regarding the effects of rifle carriage in biathlon is lacking. READ MORE

  7. 5. Hydrogen Production by Integration of Fluidized Bed Heat Exchanger in Steam Reforming of Natural Gas

    Author : Viktor Stenberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BECCS; Steam reforming; CCS; Hydrogen; fluidized bed heat exchanger; Oxygen carrier aided combustion; chemical-looping combustion;

    Abstract : The possibility to integrate fluidized beds as heat sources for steam reforming in hydrogen production plants is examined in this work. Sites with large-scale production and consumption of hydrogen such as refineries are considered as especially interesting. READ MORE
