  1. 1. Collective properties of magnetic mesospins

    Författare :Erik Östman; Björgvin Hjörvarsson; Vassilios Kapaklis; Nicolas Rougemaille; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; artificial spin ice; magnetic nano-structures; mesoscopic spin systems; mesospins; mixed spin dimensionalities; interaction modifier; engineering of energy landscape; emergence;

    Sammanfattning : Mesoscopic spin systems consist of an ensemble of lithographically patterned nanomagnetic elements - mesospins. The interactions between the mesospins, can be designed at will by altering their lateral arrangement, enabling the study of collective magnetic order in a wide range of systems. LÄS MER

  3. 2. Antimicrobials in sewage treatment plants : occurrence, fate and resistance

    Författare :Marcus Östman; Mats Tysklind; Jerker Fick; Erik Björn; Klaus Kümmerer; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biocides; antibiotics; sewage treatment plants; wastewater; sludge; ozonation; activated carbon; antibiotic resistance; antimicrobials; mass flows; LC-MS MS; environment; advanced water treatment;

    Sammanfattning : The World Health Organization (WHO) has identified antibiotic resistance as a major threat to human health. The environment has been suggested to play an important role in the emergence of antibiotic resistant bacteria. The external environment can act as a source of resistance genes that could potentially be transferred into human pathogens. LÄS MER

  4. 3. "Ja bare skrivar som e låter" : En studie av en grupp Närpesungdomars skriftpraktiker på dialekt med fokus på sms

    Författare :Anna Greggas Bäckström; Lars-Erik Edlund; Ann-Catrine Edlund; Jan-Ola Östman; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; literacy; literacy practices; SMS Short Message Service ; dialect; young people; identity; Modern Swedish; Scandinavian Languages; nordiska språk;

    Sammanfattning : The thesis studies the literacy practices of a group of young people in Närpes in southern Ostrobothnia, Finland with focus on SMS (Short Message Service), both in Standard Swedish and in dialect, but for the most part written in dialect. The aim of the investigation is to describe this writing as a social marker (young people against adults) and its function as an identity act. LÄS MER
