  1. 1. Making Radical Cations Live Longer

    Author : Ola Persson; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; spin trapping.; 3-hexafluoropropan-2-ol; 3; 1; thallium III -based oxidants; Radical cations; electron paramagnetic resonance; Physics; Fysik; Chemistry; Kemi;

    Abstract : The acid-catalyzed rearrangement of 1,4,5,8-tetramethylnaphthalene was used to determine the acidity of media used for EPR spectral studies of radical cations. The radical cations of methyl-substituted naphthalenes were shown to undergo dimerization reactions. READ MORE

    Abstract : This thesis proposes methodologies to improve heavy vehicle design by reducing the total cost of ownership and by increasing energy efficiency and safety. Environmental issues, consumers expectations and the growing demand for freight transport have created a competitive environment in providing better transportation solutions. READ MORE

  3. 3. Steering Based Lateral Performance Control of Long Heavy Vehicle Combinations

    Author : Sogol Kharrazi; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trailer Swing; Active Steering; Offtracking; Heavy Vehicle; Lateral Performance; Sine with Dwell; Accident Analysis; Longer Combination Vehicle; Rearward Amplification;

    Abstract : In this thesis the lateral performance of heavy vehicle combinations, specifically longer combination vehicles, is discussed. The use of longer combination vehicles is promoted by their positive impact on the traffic congestion problem, as well as their economic and environmental benefits due to reduced fuel consumption and emissions.

  4. 4. Clinical pharmacokinetics and pharmacodynamics of antimalarial combination therapy

    Author : Sofia Friberg Hietala; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : pharmacokinetics; pharmacodynamics; antimalarials; artemisinins;

    Abstract : In the face of growing drug resistance, the World Health Organization (WHO) has issued recommendations strongly encouraging the use of combination therapies to combat uncomplicated malaria. Amongst the most effective treatments are those combining an artemisinin derivative with a longer acting component such as amodiaquine, lumefantrine or piperaquine. READ MORE

  5. 5. Pharmacoepidemiologic Studies of Diabetes Mellitus - with special reference to - Glucose Control and Prognosis of Type 2 Diabetes

    Author : Jonny Olsson; Samhällsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetology; secreting systems; Endocrinology; cohort study; longitudinal study; cross-sectional study; mortality; diabetes mellitus; Pharmacoepidemiology; prevalence; type 2 diabetes; diabetes costs; short-term sick-leave; premature retirement; production losses; inpatient care; glycaemic control; fasting blood glucose; oral antihyperglycaemic agents; sulphonylurea; metformin; insulin; combination treatment; drug utilization; prescribed daily doses; safety; effectiveness; Endokrinologi; sekretion; diabetologi;

    Abstract : The efficacy and safety of antihyperglycaemic drugs have been evaluated in one American and one British randomized clinical trial, which have given contradictory results. The positive results of the latter may be more convincing as it included a greater number of patients and as its duration was longer. READ MORE
