  1. 1. Some Aspects on Contamination Control in Hospitals- Observations and Measurements

    Författare :Catinka Ullmann; Chalmers tekniska högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Source strength; Tissue and cells establishments; Ultraclean air operating rooms; Microbial cleanliness; Autoclaves; Contamination control; Door openings; Airborne contamination risks;

    Sammanfattning : Measurements of the cleanliness level have been performed in operating rooms classified as tissue and cells establishments for bone tissue to compare the results with the requirements given in the Tissue and Cells Directives of the European Union (EUTCD). The results show that the requirements are not always fulfilled. LÄS MER

  3. 2. A study of contaminated lubricants concerning wear, rheological properties and sample withdrawal

    Författare :Sven Berg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : The wear of a machine, whether it is due to fatigue or abrasive wear, will add contaminants, in the form of particulates, to the system in question. Since a total breakdown of the machine can be rather costly, one wants to be able to foresee breakdowns and increase the machine life. LÄS MER

  4. 3. Evaluation of Modern Irrigation Techniques with Brackish Water

    Författare :Tarek Selim Aboulila; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Soil water; Soil Salinity; Drip irrigation; HYDRUS-2D 3D; El-Salam Canal; Egypt.;

    Sammanfattning : Modern irrigation techniques are becoming increasingly important in water-scarce countries especially in arid and semiarid regions. Higher crop production and better water use efficiency are usually achieved by drip irrigation as compared to other irrigation methods. LÄS MER

  5. 4. Postoperative mediastinitis : risk factors, wound contamination, diagnostic possibilities

    Författare :Catarina Yael Bitkover; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :postoperative mediastinitis; risk factors; coaglase-negative staphylococci; pulsed field gel electrophoresis; computed tomography; granulocyte scintigraphy; inflammation; postoperative infection; procalcitonin; sternotomy; heart surgery;

    Sammanfattning : The aim of these studies has been to investigate different aspects of postoperative mediastinitis. Radiological investigations and biochemical markers of infection and inflammation were examined, risk factors analyzed and spread of bacteria during operation studied. LÄS MER

  7. 5. Salmonella in pigs : infection dynamics of different serotypes

    Författare :Julia Österberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : In recent years several incidents of feed-borne spread of Salmonella spp. have been documented in Swedish pig herds, including serotypes previously not associated with pigs. In this thesis two feed-associated serotypes (S Cubana and S Yoruba) were compared with two serotypes commonly detected in pigs (S Typhimurium and S Derby). LÄS MER
