  1. 1. 3D Magnetic Nulls and Regions of Strong Current in the Earth's Magnetosphere

    Författare :Elin Eriksson; Andris Vaivads; Hans Nilsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Magnetic Nulls; Particle Acceleration; Current sheets; Magnetic reconnection; Magnetosphere; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

    Sammanfattning : Plasma, a gas of charged particles exhibiting collective behaviour, can be found everywhere in our vast Universe. The characteristics of plasma in very distant parts of the Universe can be similar to characteristics in our solar system and near-Earth space. LÄS MER

  3. 2. Electron energization in near-Earth space : Studies of kinetic scales using multi-spacecraft data

    Författare :Elin Eriksson; Andris Vaivads; Masahiro Hoshino; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetic reconnection; electron acceleration; electron heating; magnetosheath; magnetotail; magnetic nulls; Cluster; Magnetospheric MultiScale; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

    Sammanfattning : Plasma, a gas of charged particles exhibiting collective behavior, is everywhere in the Universe. The heating of plasma to millions of degrees and acceleration of charged particles to very high energies has been observed in many astrophysical environments. How and where the heating and acceleration occur is in many cases unclear. LÄS MER

  4. 3. Undervisning med stöd av förproducerade material : Ett närmande av naturvetenskap i förskolan

    Författare :Elin Eriksson; Monika Vinterek; Annie-Maj Johansson; Sven Persson; Högskolan Dalarna; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; teaching; learning; pre-produced teaching materials; preschool; early childhood education; natural science; “Science and Technology for All”;

    Sammanfattning : This thesis aims to develop an understanding of the possibilities and challenges pre-produced teaching materials present to teachers and the learning opportunities children are offered in teaching that uses such materials. To do this a study of preschool teachers and children from three preschool departments in Sweden was carried out. LÄS MER

  5. 4. Investigations of human cortical processing of gentle touch. A study with time-resolved electro-magnetic signal analysis

    Författare :Elin Eriksson Hagberg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aβ afferent; C-tactile; touch; EEG; MEG; SEEG;

    Sammanfattning : The present work summarizes investigations of the temporal correlates of brain activity elicited by gentle, moving touch on the hairy skin in healthy participants and in epilepsy patients. Light touch to the hairy skin activates two distinct afferent classes: fast conducting, Aβ afferents and slowly conducting C-tactile (CT) afferents. LÄS MER

  7. 5. Roles of Androgens in Cardiovascular Physiology and Pathophysiology

    Författare :Elin Svedlund Eriksson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; androgens; androgen receptor; atherosclerosis; myocardial infarction; immune system; SARMs; male mice;

    Sammanfattning : ABSTRACT Atherosclerosis is the major underlying cause of cardiovascular disease, such as myocardial infarction (MI) and stroke, and these conditions are the leading causes of death both in Sweden and globally. The immune system is involved in the pathogenesis of atherosclerosis as well as post-MI cardiac injury. LÄS MER
