1. Land Use and Land Cover Changes in Europe and the Impact on Near-Surface Wind Speed in Sweden
University essay from Göteborgs universitet/Institutionen för geovetenskaperAbstract : Investigations of Land use and land cover change (LULCC) have recently become of increasing interest. This trend occurs not only based of the importance of biogeochemical processes such as carbon sequestration, but also because of their climate impacts caused by changed biogeophysical properties.

2. Morphological study of PS/PMMA-matrix on glass, related to vapour pressure, mass-fraction, and size
University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)Abstract : The objective of this study is to observe how changing amount or ratio between dried mixes of poly-methyl-methacrylate and poly-styrene change the surface appearance, and how the results might inform future design of Organic photovoltaic cells, whom are based on polymer mixtures and heavenly dependent on the arrangement of polymers. An atomic force microscope was used on glass surfaces coated in a poly-methyl-methacrylate/poly-styrene matrix and dried from either dichloromethane or ethyl-acetate to determine surface appearance.
