1. 1. Aspects of Bacterial Resistance to Silver

   Författare :Susanne Sütterlin; Åsa Melhus; Björn Olsen; Roland Möllby; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antimicrobial resistance; Silver resistance; Clinical Bacteriology; Klinisk bakteriologi;

   Sammanfattning : Bacterial resistance to antibiotics has increased rapidly within recent years, and it has become a serious threat to public health. Infections caused by multi-drug resistant bacteria entail higher morbidity, mortality, and a burden to health care systems. LÄS MER

3. 2. Copper and Silver Metallization for High Temperature Applications

   Författare :Shabnam Mardani; Shili Zhang; Hans Norström; Jörgen Olsson; Christophe Detavernier Detavernier; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallization; Copper; Silver; Tantalum; High tempreture; Diffussion; Electromigration; Stability;

   Sammanfattning : High-temperature electrical- and morphological-stability of interconnect is critical for electronic systems based on wide band gap (WBG) semiconductors. In this context, the thermal stability of both Ag and Cu films with Ta and TaN films as diffusion barriers and/or surface-capping layers at high temperatures up to 800 oC is investigated in this thesis.

4. 3. DESIREE: Instrumentation Developments and Hot Metal Cluster Decays

   Författare :Emma K. Anderson; Henning Schmidt; Henrik Cederquist; Henning Zettergren; Oded Heber; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DESIREE; microchannel plate; clusters; spontaneous decay; small metal cluster anions; silver; copper; gold; carbon dianions; fragmentation; vibrational autodetachment; DESIREE; mikrokanalplattor; kluster; spontana sönderfall; små metallklusteranjoner; silver; koppar; guld; kol di-anjoner; fragmentering; Physics; fysik;

   Sammanfattning : This thesis presents instrumentation developments and measurements performed at the Double ElectroStatic Ion Ring ExpEriment, DESIREE, at Stockholm University. DESIREE operates at cryogenic temperatures ~13 K, with very low background pressures of ~10-14mbar, allowing the observation of stored ions to long times of tens of seconds and longer. LÄS MER

5. 4. Mercury-induced autoimmunity : Genetics and immunoregulation

   Författare :Monika Hansson; Manuchehr Abedi-Valugerdi; Marita Troye-Blomberg; Lucette Pelletier; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mercury; autoimmunity; collagen-induced arthritis; Th1 Th2; silver; tight-skin 1 mice; Immunology; Immunologi;

   Sammanfattning : The existence of immune self-tolerance allows the immune system to mount responses against infectious agents, but not against self-molecular constitutes. Although self-tolerance is a robust phenomenon, in some individuals as well as in experimental models, the self-tolerance breaks down and as a result, a self-destructive autoimmune disease emerges.

7. 5. Survival of infectious agents and detection of their resistance and virulence factors

   Författare :Eva Tano; Åsa Melhus; Jan Sjölin; Marie-Louise Danielsson-Tham; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Transportation system; swab; polymicrobial samples; Neisseria gonorrhoeae; bacteremia; exotoxins; Staphylococcus aureus; TSST-1; silver; silver resistance; wound dressing; sil genes; laundry; tumble drying; bacterial decontamination;

   Sammanfattning : In the first study, three different transport systems for bacteria were evaluated. The CLSI M40-A guideline was used to monitor the maintenance of both mono- and polymicrobial samples during a simulated transportation at room temperature that lasted 0-48 h. LÄS MER
