  1. 1. Molecular-Level Investigations of Water-Organic Systems of Atmospheric Relevance

    Författare :Sofia M. Johansson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; EMB method; desorption kinetics; water uptake; organic surfaces;

    Sammanfattning : It is known that aerosol particles may have warming and/or cooling effects on the climate and negative health effects that depend on their chemical and physical properties. However, current understanding of atmospheric particles’ effects is poor due to the diversity of their constituents and associated variations in properties. LÄS MER

  3. 2. Feasibility, safety, and diagnostic potential of endomyocardial micro-biopsies

    Författare :Arvin Chireh; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Endomyocardial biopsy (EMB) is considered a reference method for diagnosis of several cardiac diseases, but the method is limited by significant complication risks and relatively poor sensitivity. Although attempts have been made to improve the tissue analysis with modern molecular methods, the safety and accuracy issues of EMB sampling remain unaddressed. LÄS MER

  4. 3. Molecular investigations of atmospherically relevant interface processes: ice formation and water accommodation on ice and organic surfaces

    Författare :Xiangrui Kong; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; atmosphere; kinetics; Environmental molecular beam; ice nucleation; supersaturation; accommodation coefficient; phase transition; alcohols; green chemistry;

    Sammanfattning : Clouds and aerosols play important roles in the climate system by affecting on atmospheric chemistry, the radiation budget of the atmosphere, and the water cycle including the formation of precipitation. Climate models with predictive power require quantitative descriptions of aerosols and clouds, but several key processes remain to be fully understood. LÄS MER

  5. 4. Cardiac muscle injury in children and experimental animals. Reflections in ECG, especially high-resolution electrocardiography

    Författare :Rolf Bennhagen; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; Kardiovaskulära systemet; Cardiovascular system; signal-averaging ECG; ischaemia; cardiac transplantation; Pediatri;

    Sammanfattning : Background and Methods: Signal-averaging ECG (SAECG), a bioelectrical processing method, is a further development of the conventional ECG. SAECG can detect voltage potentials in the microvolt range and provide a noise-reduced determination of QRS duration. Extended frequency spectra can be analysed. LÄS MER

  7. 5. Improving Fuel Efficiency of Commercial Vehicles through Optimal Control of Energy Buffers

    Författare :Mohammad Khodabakhshian; Jan Wikander; Lei Feng; Johan Ölvander; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy buffer; Optimal control; Hybrid electric vehicle; Engine cooling system; Equivalent consumption minimization strategy; Model predictive control; Machine Design; Maskinkonstruktion;

    Sammanfattning : Fuel consumption reduction is one of the main challenges in the automotiveindustry due to its economical and environmental impacts as well as legalregulations. While fuel consumption reduction is important for all vehicles,it has larger benefits for commercial ones due to their long operational timesand much higher fuel consumption. LÄS MER
