C. & Lihavainen, H. 2013: Deterioration of air quality across Sweden due to transboundary agricultural burning emissions. Boreal Env. Res. 18: 19-36. We analyzed measurements of aerosol and trace-gas concentrations from sites across Sweden before and during a series of agricultural wildland fires in eastern Eu
The European Security Strategy (ESS) developed in 2003 and the National Security Strategy of the United States of America (NSS) was issued in 2002. In this thesis these two documents are compared and analyzed with reference to the securitization theory. The comparison focus on identified threats and how they aim to refute them. The choice of documents is partly based on, them being the first secu
In this thesis the relationship between socioeconomic equality and democratic consolidation is evaluated through a case study of Bolivia. The country is one of the poorest in the Latin American region and has suffered a large degree of socioeconomic inequality. The country ended the transition to democracy in 1985 and has since then met challenges in consolidating the democracy and create stable p
1996 infördes miljöersättning för skötsel av landskapselement som ligger i eller i anslutning till åkermark i Sverige. Landskapselement i jordbrukslandskapet såsom öppna diken, stenmurar, åkerrenar och åkerholmar är viktiga småbiotoper för många djur- och växtarter. Idag (2013) kan miljöersättning för kultur- och naturmiljöer i odlingslandskapet (även kallat kulturmiljöstöd) sökas av lantbrukare sIn 1996, an agri-environmental support scheme was introduced in Sweden to compensate farmers for the maintenance of landscape elements located in or adjacent to cropland. Landscape elements in the agricultural landscape, for example ditches, stone walls, field margins and field islets, are important small biotopes for many animal and plant species. Today, farmers who remove bushes and trees (with
The purpose of this thesis was to contribute to a more holistic understanding of youth experiences under the phenomenon of societal transitions caused by processes of modernization. Bhutan has been subjected to major changes in terms of economic development, political and societal transitions. The group mostly associated with this modernization and globalization process is the youth living in the
Populärvetenskaplig sammanfattning: Under de senaste åren har det varit mycket fokus på biobränsle som ett sätt att reducera konsumtionen av fossila bränslen och utsläppet av växthusgaser. Flytande biobränslen kan blandas med bensin och diesel som ersättning för fossila bränslen i transportsektorn. Blandningar av biobränsle och bensin eller diesel kan användas direkt i omodifierade motorer och detUnder the Kyoto protocol the European Union (EU) has committed itself to reducing its greenhouse gas emissions to 92% of 1990 levels. Carbon sequestered in agriculture is allowed to be countered against emissions to help meet the targets. Biofuels represent an infinite possibility to sequester carbon in agriculture, as they reduce emissions by replacing fossil fuels. The EU has set the target that
Bladyteindex för skog är ett mått på mängden blad i skogen. Bladyteindexet används i klimatmodeller för att uppskatta viktiga biologiska processer för skogen som fotosyntes, evapotranspiration och kolutbyte med atmosfären. Dessa modeller behöver bladyteindexdata över stora skogsarealer, som rimligtvis inte kan mätas för hand. Man har upptäckt samband mellan satellitdata i form av skogars reflektanGround reflectance of forests has been suggested as a main source weakening the strength of relationships using satellite reflectance to predict forest leaf area index (LAI), a key input variable in models of carbon balance and global circulation. In this project a radiative transfer model was used to simulate the influence of ground reflectance in forest canopy reflectance in twenty forest stands
Environmental problems are a discussed subject in the world. The reason for this is that natural disasters are becoming more and more visible. EU is working to reduce the Union's contribution to the greenhouse effect. The goal is to reduce greenhouse gases with 20% by 2020 and 20% of the energy used should come from renewable energy sources. The EU’s Energy Performance of Building Directive (E
Atmospheric aerosol samples from a boreal forest (Hyytiala, April 2007), a rural site in Hungary (K-puszta, summer 2008), a polluted rural area in Italy (San Pietro Capofiume, Po Valley, April 2008), a moderately polluted rural site in Germany located on a meadow (Melpitz, May 2008), a natural park in Spain (Montseny, March 2009) and two urban background locations (Zurich, December 2008, and Barce
The aim of this study was to examine the infiltration rate of water and some parameters affecting it. Especially the land usage, the abundance of roots and macropores were investigated. A field study was carried out on western Java in Indonesia, on the slope of Mount Salak. The study compared four different land uses; i.e. forest, shrub areas, tree plantation and cropland since there was a high o
With the development of society the risks have become more complex and difficult to overview. Not least because of the inter¬dependencies that exist between them. This master thesis aims to study critical societal functions dependencies in the primary care in Skåne and to investigate the possibility of intro¬ducing some kind of basic security levels in those functions. The study includes four main
Skog täcker 56% av all markyta i Sverige, och 95% av denna skogsmark används inom skogsbruk. Detta gör att skog är en grundläggande del av national- och landsbygdsekonomin. Varje år så blir Europas skogar utsatta för stormskador, vilket har lett till analyser av vindinteraktioner med skog, och forskning inom de alternativ som finns för att minska stormskador. Att förutspå vindklimat och dess föränIn Sweden forests cover 56% of the total land cover, within which 95% of these forests are used for forestry. This makes forests a fundamental part of the national and rural economy. Each year however, forest stands across Europe are damaged by wind, which has prompted several analyses on wind interactions with forests, and what alternatives there are to mitigate storm damage. Predicting wind clim
The purpose of this study has been to test if GIS based methods calibrated with limited local data can be used to determine the origin and quantity of phosphorus transport to and within a small eutrophic lake, and to assess the effects of this transport on the lake water quality. The lake studied is Lake Flaten in Salem municipality, Sweden. The objectives have been achieved by delineating catchme
HAMLET is a protein-lipid complex with a specific and broad bactericidal and tumoricidal activity, that lacks cytotoxic activity against healthy cells. In this study, we show that HAMLET also has general immune-stimulatory effects on primary human monocyte-derived dendritic cells and macrophages (Mo-DC and Mo-M) and murine RAW264.7 macrophages. HAMLET, but not its components alpha-lactalbumin or o
Geospatial information is indispensable for various spatially-informed analysis and decision-making, e.g. traffic analysis and built environment processes. Geospatial data often must be integrated for meaningful analysis, whereas such integration is challenging due to siloed data organization, semantic heterogeneity and multiple representation of geospatial data. Moreover, the visualization of geo
