6. Sleep-disordered breathing in women : Associations with cardiovascular disease and the significance of sleep apnea during REM sleep
Abstract : Background: Sleep-disordered breathing (SDB) is associated with an increased risk of cardiovascular disease, but it is unclear which elements of SDB that are most harmful to the cardiovascular system and whether the associations observed in men also apply to women.Aim: To investigate associations between different aspects of SDB and cardiovascular disease in womenMethods and results: All four papers were based on participants in “Sleep and Health in Women” (SHE), a population-based cohort study of women.

7. A study of micro-particles in the dust and melt at different stages of iron and steelmaking
Abstract : The dust particles generated due to mechanical wear of iron ore pellets and clusters formed in molten stainless steel alloyed with rare earth metals (REM) are considered in this study. Firstly, the influence of the characteristics of iron ore pellets, applied load on a pellet bed and partial reduction of the pellets on the size distribution of the generated dust was investigated.

8. Electrochemical evaluation of new materials in polymer electrolyte fuel cells
Abstract : Polymer electrolyte fuel cells (PEFC) convert the chemical energy in hydrogen to electrical energy and heat, with the only exhaust being water. Fuel cells are considered key in achieving a sustainable energy sector. The main obstacles to wide scale commercialization are cost and durability. READ MORE

10. Three Dimensional Determinations of Inclusions in Ferroalloys and Steel Samples
Abstract : As the requirements on material properties increase, there has been a demand on an additional knowledge on the effect of impurities in the ferroalloyson the steel cleanness. Thus, the number, morphology, size and composition of inclusions in sixdifferent ferroalloys (FeTi, FeNb, FeSi,SiMn, LC and HC FeCr) were investigatedin this study. READ MORE
