    Keywords : Thunder; Convection; Stability Indices; Climate change; Regional Climate Model; RCA4; Åska; konvektion; stabilitetsindex; klimatförändring; regional klimatmodellering; RCA4;

    Abstract : In the last 100 years, a rise in the global mean temperature has been noted, and projections show even higher temperatures in the future. The temperature rise can lead to changes in the weather patterns and therefore the thunderstorm activity in a future warmer climate has been investigated in this study. READ MORE

  2. 7. Capacity estimates and Poincaré inequalities for the weighted bow-tie

    University essay from Linköpings universitet/Matematiska institutionen; Linköpings universitet/Tekniska fakulteten

    Author : Andreas Christensen; [2017]
    Keywords : Bow-tie; Capacity; Metric space; Muckenhoupt weight; Poincaré inequality; Upper gradient; Weight function;

    Abstract : We give a short introduction to various concepts related to the theory of p-harmonic functions on Rn, and some modern generalizations of these concepts to general metric spaces. The article Björn-Björn-Lehrbäck [6] serves as the starting point of our discussion. READ MORE

    Abstract : SLU (Swedish University of Agricultural Sciences) have had a project ongoing in a catchment area in southern Skåne for 20 years where they study how pesticide occurrence in surface waters correlate to the sort and amount used on the agricultural fields. A new project started by SGI (Swedish Geotechnical Institute) called PEGASUS (PEsticide occurrence in Groundwater, A Study for sustainable Use in Skåne) has begun an investigation in the same catchment to study the pesticide behavior and effects in the deeper groundwater.

  5. 10. Hydrauliken i Ångersjöns fosforfällor : bestämning av flödesvägar och åtgärdsförslag för optimal fosforbindning vid avloppsrening med reaktiva filter

    University essay from SLU/Dept. of Soil and Environment

    Author : Ellinor Jansson; [2008]
    Keywords : fosforrening; Ångersjön; filtermaterial;

    Abstract : Discharge of untreated wastewater leads to unnaturally high levels of nitrogen and phosphorus in rivers, lakes and the sea, which results in unbalanced ecosystems with eutrophication and lack of oxygen. Part of the phosphorus in surface waters is coming from on-site wastewater treatment from scattered households with unsatisfactory purification. READ MORE
