1. Fastläggning av arsenik med nollvärt järn i mikrostorlek : Uppföljning av ett pilotskaleförsök
Uppsats för yrkesexamina på avancerad nivå,Sammanfattning : Land contaminated with arsenic is a major problem as arsenic is toxic and poses a major health risk to both humans and animals. There are several remediation methods, both in-situ and ex-situ, to prevent and deal with pollution problems in different ways. LÄS MER
2. Soil compaction and the effect on infiltration in urban green environments : A study based on field measurements and HYDRUS 1D modelling
Uppsats för yrkesexamina på avancerad nivå,Sammanfattning : The consequences of recent flooding and extreme rain events have highlighted the importance of proper urban planning and preventative measures for storm water management. As cities become more urbanized the significance of permeable surfaces such as parks and other urban green spaces increases which infiltrate the water into the ground. LÄS MER
3. Differences and similarities in stand characteristics after prescribed burning and wildfire : implications for conservation of forest biodiversity
Master-uppsats, SLU/Dept. of EcologySammanfattning : 1. Wildfires are a natural disturbance in the boreal forests of Fennoscandia and have shaped and formed forests in the past, resulting in very heterogeneous forests containing large amounts of dead and living trees in various age classes. LÄS MER
4. The assessment of ecosystem services provided by forest edge effects on fields in a fragmented Swedish agricultural landscape : a methodological framework
Master-uppsats, SLU/Dept. of Crop Production EcologySammanfattning : Agricultural expansion, prompted by increasing global food demand, has fragmented, simplified, and homogenized the landscape in the last decades. The resilience and sustainability of croplands are at stake, resulting in a hight vulnerability to climate change, and having major impacts on environmental protection, biodiversity preservation and food security. LÄS MER
5. In-vivo imaging of root growth in response to localized mechanical stress
Master-uppsats, SLU/Dept. of Soil and EnvironmentSammanfattning : By taking up nutrients and water, root growth has an important influence on plant growth and productivity. Thereby, root growth is influenced by its surrounding soil conditions, which vary spatially even on a small scale. Hence, different parts of the root system are exposed to different penetration resistances in the soil. LÄS MER
