  2. 1. Isocyanates - methodology for gas and particle generation, sampling and detection

    Author : Daniel Gylestam; Marianne Dalene; Gunnar Skarping; Daniel Karlsson; Dhimiter Bello; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Isocyanate; PUR; Dry sampler; PTR-MS; Transfer line; PPE; Environmental Chamber; Respirable Particles; Denuder Impactor; Aerosol; Particles; Impinger; air sampling; LC-MS; di-n-butylamine; DBA; ICA; MIC; HDI; TDI; IPDI; MDI; Occupational Exposure; Exposure; Occupational Health; Analytical Chemistry; analytisk kemi;

    Abstract : Isocyanates are mainly used in the industry for the production of polyurethane (PUR) plastics. Workers are at risk of being exposed during the manufacturing of PUR. During thermal degradation of PUR, isocyanates are released and workers involved in hot work such as fire-fighting, welding etc. may also be exposed. READ MORE

  4. 2. Analytical and Numerical Developments in Strongly Correlated Systems: Perspectives from TDDFT and Green's Functions

    Author : Daniel Karlsson; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Many-Body Perturbation Theory; Hubbard model; TDDFT; Green s function; DFT; Quantum Transport; Disorder; Fysicumarkivet A:2014:Karlsson;

    Abstract : This thesis investigates different methods for treating strongly correlated systems, and discusses their respective strengths and weaknesses. Many of the results presented in this thesis come from comparing the different methods and approximations to exact results. READ MORE

  5. 3. Airborne Isocyanates, Aminoisocyanates and Amines

    Author : Daniel Karlsson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental health; Miljökemi; Environmental chemistry; amines; aminoisocyanates; isocyanates; polyurethane; exposure; occupational; thermal degradation; chemiluminescence; mass spectrometry; Liquid chromatography; gas chromatography; Miljömedicin; Occupational health; industrial medicine; Yrkesmedicin; arbetsmiljömedicin;

    Abstract : Isocyanates are used in the production of polyurethane (PUR). Exposure to isocyanates is associated with respiratory disorders and may occur during production or processing of PUR. During thermal degradation of PUR, amines and aminoisocyanates are formed in addition to isocyanates. READ MORE

  6. 4. Specification of unique neuronal sub-types by integration of positional and temporal cues

    Author : Daniel Karlsson; Stefan Thor; Mattias Alenius; Jeremy S. Dasen; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The nervous system contains vast numbers of neuronal sub-types, generated at specific time points, in the proper location, and in proper numbers. One of the fundamental issues in neurobiology is to understand the molecular genetic mechanisms that underlie the generation of this daunting neuronal diversity. READ MORE

  7. 5. Aspects of the use of medical decision-support systems : the role of context in decision support

    Author : Daniel Karlsson; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : There is a great need today for distribution of medical information. The amount of information is growing quickly, and information that could potentially influence clinical practice fails to reach health care professionals. The supply of information to health care has from the start been the main goal of medical informatics. READ MORE
