  1. 6. Mass Spectrometry with Electrospray Ionization from an Adjustable Gap

    Författare :Patrik Ek; Åsa Emmer; Johan Roeraade; Per M. Claesson; Ulrika Nilsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electrospray ionization; mass spectrometry; nanoelectrospray; ESI; MS; chip; emitter; gap; liquid bridge; nozzle; peptides; Analytical chemistry; Analytisk kemi;

    Sammanfattning : In this thesis the fabrication and analytical evaluation of two new electrospray emitters utilized for mass spectrometry analysis is presented. The emitters are based on a new concept, where the spray orifice can be varied in size. The thesis is based on two papers. All present-day nanoelectrospray emitters have fixed dimensions. LÄS MER

  3. 7. Health Economic Aspects of Injury Prevention at the Municipal Level

    Författare :Harald Gyllensvärd; Kent Lindqvist; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Unintentional injuries are a global health problem, which in 1996 was estimated to cause up to 3 million deaths per year. In Sweden, about 4,600 people die annually due to external causes of morbidity and mortality (injuries and poisoning). Among children 1 to 17 years old, injuries are the leading cause of death in Sweden for both boys and girls. LÄS MER

  4. 8. Clonal structure and reproductive biology in the gynodioecious herb Glechoma hederacea L. Lamiaceae

    Författare :Marie Widén; Biologiska institutionen; []

    Sammanfattning : Clonal structure and reproductive biology in the gynodioecious herb Glechoma hederacea L. Lamiaceae The frequencies of females, hermaphrodites and partially male-sterile (PMS) genets of Glechoma hederacea were estimated in natural populations in S Sweden. The frequency of females and PMS genets in natural populations varied from 0 to 100%. LÄS MER

  5. 9. Knowing me, knowing you : Mentalization abilities of children who use augmentative and alternative communication

    Författare :Annette (Anett) Sundqvist; Jerker Rönnberg; Charlotta Plejert; Susan Balandin; Linköpings universitet; []
    Nyckelord :Mentalization; active participation; social networks; children who use augmentative and alternative communication; Mentaliseringsfömåga; sociala nätverk; aktivt deltagande; barn som använder sig av alternativ och kompletterande kommunikation; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Sammanfattning : The present thesis investigated several components important to the understanding of mentalization for children who use augmentative and alternative communication (AAC). The result of the thesis demonstrated that non-verbal mental age correlated significantly with mentalization tasks, and that the participants did not significantly differ compared to a nonverbal age-matched group of children without disabilities.

  7. 10. Biomarkers of aromatic isocyanates in exposed workers

    Författare :Pernilla Lind; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adducts; biomarkers; exposure; occupational; methylenediphenyl diisocyanate; toluene diisocyanate; amines; isocyanates; polyurethane; Gas chromatography; mass spectrometry; Occupational health; industrial medicine; Yrkesmedicin; arbetsmiljömedicin;

    Sammanfattning : The aromatic isocyanates, toluene diisocyanate (TDI) and methylenediphenyl diisocyanate (MDI), are used in the production of polyurethane (PUR) foams, paints, elastomers and glues. The use of isocyanates is increasing, and exposure to isocyanates is the most common cause of occupational asthma. LÄS MER
