    Abstract : Det är svårt att tänka sig dagens samhälle utan katalys då många av de produkter som vi använder dagligen framställs med någon form av katalysator med tillämpningar som sträcker sig från kemikalieproduktion till avgasrening. Den mest kända katalysatorn är nog bilkatalysatorn som används för att omvandla de mest skadliga bilavgaserna till mindre skadliga gaser. READ MORE

  2. 2. Aetiology in community-acquired pneumonia

    University dissertation from Stockholm : Karolinska Institutet, Dept of Medicine, Solna

    Author : Niclas Johansson; Karolinska Institutet.; Karolinska Institutet.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Background: Although community-acquired pneumonia (CAP) is a common and well-known disease, its microbial aetiology is still not well characterized. During the past few years nucleic acid detection using real-time polymerase chain reaction (PCR) has been developed for detection of many bacterial and viral pathogens causing respiratory tract infections.

  5. 5. Neonatal Exposure to Highly Brominated Diphenyl Ethers and Perfluorinated Compounds Developmental Dependent Toxicity and Interaction

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Niclas Johansson; Uppsala universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi; Ecotoxicology; ekotoxikologi;

    Abstract : This thesis investigated the developmental neurotoxic effects of neonatal exposure to highly brominated diphenyl ethers (PBDEs) and perfluorinated compounds (PFCs), alone or in combinations, during a critical period of the brains’ rapid growth and development, in mice. The compounds investigated were the decaBDE (PBDE 209), nonaBDE (PBDE 206), octaBDE (PBDE 203), heptaBDE (PBDE 183), and three PFCs, PFOS, PFOA, and PFDA. READ MORE
