16. The high Arctic summer aerosol : Size, chemical composition, morphology and evolution over the pack-ice
Sammanfattning : Aerosol particles, especially in the high Arctic are still not very well represented in climate models. Particle size and number concentrations are strongly under-predicted and temporal variations of aerosol composition and size are still not very well understood, mainly due to the sparsity of observations.

17. Fuel conversion and ash formation interactions : a thermochemical study on lignocellulosic biomass
Sammanfattning : Biomass is considered to be CO2 neutral, and to be able to reduce the dependency on fossil fuels the need for expanded and sustainable biomass feedstock is increasing. Ash-related problems are some of the most important aspects of this increasing use of new biomass assortments in thermal energy conversion systems. LÄS MER
18. Altered body composition in adults with complex congenital heart disease
Sammanfattning : Introduction: Thanks to achievements in paediatric heart surgery and medicine, the population of adults with surgically repaired or palliated congenital heart defects is growing. Many of these adults have reduced exercise capacity, weaker muscular strength and shorter height, all of which suggest an altered body composition. LÄS MER
19. Effect of environmental factors on bacterioplankton community composition, diversity and functionality
Sammanfattning : The ocean covers more than 70 % of the Earth surface and represents the largest ecosystem on Earth. Bacteria are an important part of the marine food web not only in remineralisation but also since they utilize dissolved organic matter (DOM) and make the energy available to higher trophic levels.

20. Composing Policy Interventions for Antibiotic Development
Sammanfattning : Antibiotic resistance is eroding the efficacy of the drugs we have and, unless future science dictates otherwise, bacteria will eventually become resistant to whatever new antibiotics we discover. We must therefore plan for a continuous stream of innovation. Unfortunately, pharmaceutical firms have left the scene to pursue more profitable areas. LÄS MER
