  4. 2. The Resting Electrocardiogram and Risk for Cardiovascular Disease : A Population-Based Study in Middle-Aged Men with up to 32 Years of Follow-Up

    Author : Christina Ström Möller; Lars Lind; Björn Zethelius; Johan Sundström; Annika Rosengren; Uppsala universitet; []
    Keywords : Medical sciences; electrocardiogram; risk factors; epidemiology; population-based studies; cardiovascular mortality; apolipoproteins; MEDICIN OCH VÅRD;

    Abstract : The aim was to contribute to the optimal use of the resting ECG by exploring, in middle-aged and elderly men, the development and regression of ECG abnormalities; the prognostic value of the ECG for cardiovascular disease compared to conventional risk factors; and the impact of age at baseline and follow-up time for prediction of cardiovascular disease.It was based on the Uppsala Study of Adult Men cohort that was started in 1970.

  5. 3. Primary Marine Aerosol : Validation of sea spray source functions using observations and transport modeling

    Author : Henrik Grythe; Johan Ström; Krejci Radovan; Bo Gustafsson; Lars Ahlm; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; marine aerosol; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Sea spray aerosols (SSA) are an important part of the climate system through their effects on the global radiative budget, both directly as scatterers and absorbers of solar and terrestrial radiation, and indirectly as cloud condensation nuclei (CCN) influencing cloud formation, lifetime and precipitation. In terms of their global mass, SSA is the largest source and has the largest uncertainty of all aerosols. READ MORE

  6. 4. Quantification of sources and removal mechanisms of atmospheric aerosol particles

    Author : Henrik Grythe; Johan Ström; Dominick Spracklen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aerosol; aerosol removal; aerosol emission; aerosol sources; FLEXPART; Arctic aerosol; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : The focus of this work has been to quantify important processes for climatically relevant aerosols, and to improve our understanding of, and ability to accurately model, aerosols in the atmosphere on a large scale. This thesis contains five papers focused on different parts of the life cycle of atmospheric aerosol particles. READ MORE

  7. 5. Impact of residential wood combustion on urban air quality

    Author : Patricia Krecl; Christer Johansson; Johan Ström; Tami Bond; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; residential wood combustion; air quality; aerosols; black carbon; polycyclic aromatic hydrocarbons; particulate matter; particle size distributions; source apportionment; positive matrix factorization; compound-specific radiocarbon analysis; Earth sciences; Geovetenskap; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Wood combustion is mainly used in cold regions as a primary or supplemental space heating source in residential areas. In several industrialized countries, there is a renewed interest in residential wood combustion (RWC) as an alternative to fossil fuel and nuclear power consumption. READ MORE
