  1. 16. Metal Cluster Reactivity. Adsorption of small molecules in biomolecular collisions

    Författare :Mats Andersson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; O2; CO; ionization potential; Con; Fen; NO; sticking probability; laser ionization; D2; Wn; Cun; Rhn; reaction probability; cluster; jellium model; Nbn; metal cluster reactivity; N2; time-of-flight mass spectrometry; Nin;

    Sammanfattning : Metal clusters can be characterized as the tiniest possible metal particles, containing only an easily counted number of atoms. In this work, reactions between metal clusters and diatomic molecules have been investigated. We have constructed an experimental set-up to produce and detect clusters, and to investigate their chemical reactivity. LÄS MER

  3. 17. Radiological evaluation of esophageal function in dysphagia with special emphasis on achalasia

    Författare :Mats Andersson; Göteborgs universitet; []
    Nyckelord :Achalasia; Dysphagia; Radiography; Barium esophagogram; Reproducibility of findings; Observer variation; Laparoscopic myotomy; Balloon dilatation; Esophageal neoplasms;

    Sammanfattning : In idiopathic achalasia, degeneration of the inhibitory innervation of the esophageal smooth muscle results in absence of primary peristalsis and in incomplete relaxation of the lower esophageal sphincter (LES). All treatments for achalasia aim at reducing the pressure gradient across the LES, thus facilitating esophageal emptying by gravity. LÄS MER

  4. 18. Synthesis and Properties of Substituted Poly(thiophenes)

    Författare :Mats Andersson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The aim of this work was to synthesize new substituted poly(thiophenes) with certain desired properties. Soluble and meltable poly(thiophenes) can be prepared if a long alkyl side-chain is attached to each thiophene ring along the polymer backbone. Such polymers show electrical conductivity when they are doped (oxidised). LÄS MER

  5. 19. Med dig vid min sida : -det vårdande mötets betydelse när barn genomgår anestesi i en högteknologisk operationsmiljö

    Författare :Lisbet Andersson; Sofia Almerud Österberg; Pauline Johansson; Susanne Knutsson; Mats Eriksson; Linnéuniversitetet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Omvårdnad; Nursing;

    Sammanfattning : Aim: The overall aim of this thesis was to contribute with knowledge of and gain a greater understanding of the encounter between children, parents, and anesthesia staff in a high-technological surgical environment.Methods: This thesis is based on four studies with descriptive, interpretive and cross-sectional designs.

  7. 20. MRSA and other resistant bacteria : prevalence, patient and staff experiences, wounds and infection control

    Författare :Helene Andersson; Bjöörn Fossum; Christina Lindholm; Mats Kalin; Eva Johansson; Sophiahemmet Högskola; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRSA; VRE; ESBL; Colonization; Infection control; Wound; Patient experiences; Staff experiences; Nursing care; Qualitative interview; Qualitative content analysis; MRSA;

    Sammanfattning : Antibiotic resistance has become a major and serious global problem in healthcare. Limited treatment options for infections caused by these organisms can lead to increased morbidity and mortality. LÄS MER
