  1. 1. Electron Heating and Acceleration at Earth’s Collisionless Bow Shock

    Författare :Martin Lindberg; Andris Vaivads; Philippe Savoini; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electron; heating; Acceleration; MMS; Shock; space; plasma; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Cosmic rays are ultra-relativistic particles traveling near the speed of light permeating the galaxy. Collisionless shock waves with their ubiquity throughout the universe and excellent capability of accelerating charged particles offer an explanation to the origin of cosmic rays. LÄS MER

  3. 2. Prenatal food and micronutrient supplementation to malnourished women in Bangladesh : Effects, Equity, and Cost-effectiveness

    Författare :Rubina Shaheen; Lars-Åke Persson; Lars Lindholm; Yemane Berhane Tsehay; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; malnutrition; pregnancy; food supplement; micronutrient supplement; birth weight; infant mortality; effectiveness; economic evaluation; equity; Bangladesh; Medical Science; Medicinsk vetenskap;

    Sammanfattning : Maternal nutrition is closely linked to child health and survival. In Bangladesh there is a high prevalence of undernutrition in the form of chronic energy deficiency [CED, Body Mass Index ... LÄS MER

  4. 3. Nutrition and Oxidative Parameters in Pregnancy, Size at Birth and Metabolic Status of the Offspring at 4.5 Years : The MINIMat Trial in Rural Bangladesh

    Författare :Emma Lindström; Eva-Charlotte Ekström; Lars-Åke Persson; Samar Basu; Tessa Roseboom; Uppsala universitet; []
    Nyckelord :Pregnancy; micronutrient deficiency; anemia; birth size; food supplementation; micronutrient supplementation; metabolic status; childhood; International Health; Internationell hälsa;

    Sammanfattning : Undernutrition and oxidative stress in fetal life and infancy may lead to adverse health outcomes in the offspring. We studied nutrition and oxidative parameters in pregnancy and their associations with birth anthropometry and metabolic status in the children. LÄS MER

  5. 4. High-speed jets and related phenomena at Earth's bow shock and magnetosheath

    Författare :Savvas Raptis; Tomas Karlsson; Drew Turner; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetosheath; solar wind; bow shock; plasma; collisionless shock; Physics; Fysik;

    Sammanfattning : Magnetosheath high-speed jets are transient and localized dynamic pressure enhancements downstream of Earth’s bow shock. Their formation has been associated with several mechanisms, including solar transient events and the dynamical evolution of the bow shock. LÄS MER

  7. 5. Electrostatic turbulence and electron heating in collisionless shocks

    Författare :Ahmad Lalti; Yuri V. Khotyaintsev; Hans Nilsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

    Sammanfattning : Collisionless shocks are one of the most peculiar phenomena in space where non-linear collective phenomena in the plasma dominate the dynamics. They are believed to be one of the most efficient particle accelerators in the universe, and have internal dynamics that are yet to be fully explored. LÄS MER
