12. Strukturkalkning av åkermark : ett sätt att minska jordbrukets bidrag till eutrofiering av vatten
Kandidat-uppsats, SLU/Dept. of Soil and EnvironmentSammanfattning : In this review article, the effect of structural liming on clay soils, which have a high leakage potential for phosphorus (P), was analyzed. The purpose was to investigate structural liming as a method to reduce the impact of agriculture on eutrophication of water sources. LÄS MER
13. Energy mapping of public buildings : A study at Älvkarlebyhus
Magister-uppsats, Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknikSammanfattning : The aim of this report is to identify all energy systems in the Skutskärs Vårdcentral and Folktandvården building, Centralgatan 12 building and the Library building to be studied in this report and carry out an investigation on whether the energy systems efficiency may be increased by improving on the elements or factors that affect the energy systems. A model of the buildings energy systems were created in Microsoft excels using the steady state method and modifying it to calculate an average heating session. LÄS MER
