  2. 21. Fourier Transform Infrared Spectroscopy in Industrial Hygiene Applications : Assessment of Emissions from and Exposures in Wood Processing Industries

    Author : Urban Svedberg; Christer Edling; Bo Galle; Hans-Erik Högberg; Nils Plato; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; FTIR; Exposure; Emission; Saw mills; Wood pellets; Tracer gas; Monoterpenes; Hexanal; Carbon monoxide; Open path FTIR; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin;

    Abstract : This thesis evaluates the use of Fourier Transform Infrared Spectroscopy (FTIR) as an approach to the increasingly difficult air sampling challenges within the field of occupational and environmental hygiene. The application of FTIR is exemplified by the assessment of emissions from and exposures in the sawmill and pellet industries. READ MORE

  4. 22. Microwave-Assisted Synthesis of C2-Symmetric HIV-1 Protease Inhibitors : Development and Applications of In Situ Carbonylations and other Palladium(0)-Catalyzed Reactions

    Author : Johan Wannberg; Anders Hallberg; David C. Rees; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; HIV; protease inhibitors; palladium; carbonylations; molybdenum hexacarbonyl; dihydropyrimidone; DHPM; microwave; cross-coupling; diazylhydrazines; carbon monoxide; synthesis; C2-symmetric; HIV-1 protease inhibitors; aminocarbonylation; fluorous; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi;

    Abstract : The HIV protease is an essential enzyme for HIV replication and constitutes an important target in the treatment of HIV/AIDS. Efficient combination therapies using inhibitors of the reverse transcriptase and protease enzymes have led many to reevaluate HIV infections from a terminal condition to a chronic-but-manageable disease in the developed world.

  5. 23. Development of Methanol-Reforming Catalysts for Fuel Cell Vehicles

    Author : Johan Agrell; KTH; []
    Keywords : PEM fuel cells; hydrogen; methanol; reforming; oxidation; reaction pathways; carbon monoxide;

    Abstract : Vehicles powered by proton exchange membrane (PEM) fuelcells are approaching commercialisation. Being inherently cleanand efficient sources of power, fuel cells constitute asustainable alternative to internal combustion engines to meetfuture low-emission legislation. READ MORE

  6. 24. Ground based measurements of upper atmospheric CO and H2O using microwave radiometry

    Author : Peter Forkman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mesosphere; carbon monoxide; microwaves; radiometry; remote sensing; water vapour;

    Abstract : Long series of continuous measurements of middle and upper atmospheric constituents are needed to be able to understand the anthropogenic influence on the atmosphere. Phenomena like ozone depletion and the enhanced greenhouse effect are examples where the role of human activities has to be well investigated in order to make the right decisions of necessary changes in our way of life.

  7. 25. Energy-metabolic aspects of ischemia and pre-treatment: studies in porcine myocardium

    Author : Katarina Ahlström; Göteborgs universitet; []
    Keywords : myocardial ischemia; adenosine; preconditioning; carbon monoxide;

    Abstract : The focus of this thesis is to clarify mechanisms involved in protective pre-treatment of ischemia by carbon monoxide (CO) and ischemic preconditioning (IP), so that new pro-tective therapies can be designed. This is studied in heart muscle, where the clinical gain would ultimately be to be able to prolong the period during a threatened myocardial infarction where permanent injury can be prevented.
