  1. 11. Decreasing organic nitrogen concentrations in European water bodies - links to organic carbon trends and land cover

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Alexis Cazorla; [2020]
    Keywords : geography; GIS; physical geography; organic nitrogen; organic carbon; land cover; eutrophication; Europe; Earth and Environmental Sciences;

    Abstract : European rivers experience increasing concentrations of total organic carbon (TOC) from terrestrial sources due to factors involving changes in land use, climate and soil acidity. However, low interest is given to the evolution of total organic nitrogen (TON) concentrations in surface waters, the links with TOC concentrations and the influence of the surrounding land cover on nutrient inputs.

  2. 12. Effects of 100 years of drainage on peat properties in a drained peatland forests in northern Sweden

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Mikaela Casselgård; [2020]
    Keywords : ash content; biodiversity; bulk density; carbon; climate; compaction; ditch; drainage; greenhouse gas emissions; groundwater level; isotopes; nitrogen; peatland; restoration;

    Abstract : Natural peatlands provide a small but persistent long-term carbon (C) sink. However, within the last century their extent in Sweden has declined by about 1.5-2.0 million hectares due to drainage activities. READ MORE

  3. 13. Volatile fatty acid production and application as external carbon source for denitrification

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Cora Michelle Döhler; [2020]
    Keywords : VFAs; co-fermentation; primary sludge; food waste; denitrification; external carbon source; MBBR;

    Abstract : By rethinking wastewater treatment plants (WWTPs) as resource recovery facilities, it is possible to de- velop the next generation of WWTPs. Moreover, it allows to accomplish environmental goals, such as reducing the CO2 footprint, and comply with increasing effluent standards regarding the concentration of nitrogen in a more sustainable way.

  4. 14. Holocene lake-level changes in the Siljan Lake District – Towards validation of von Post’s drainage scenario

    University essay from Lunds universitet/Geologiska institutionen

    Author : Savvas Paradeisis-Stathis; [2020]
    Keywords : Lake Siljan; Dalarna; basin isolation; catastrophic drainage; early Holocene; lake sediments; XRF scanning; C N ratio; magnetic susceptibility; pollen; Ancylus Lake; Earth and Environmental Sciences;

    Abstract : The Dalarna province in south-central Sweden shows a great variety of geological evidence from the Late Quaternary. A peculiar deglaciation pattern, along with unique hydrological conditions, has left a lot of space for speculations over the palaeoenvironmental conditions during the early Holocene. READ MORE

  5. 15. How to improve the soilless cultivation of sweet basil looking at light and nutrition?

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Hedvig Säll; [2020]
    Keywords : hydroponics; aeroponics; sweet basil; essential oils; vertical farming;

    Abstract : Sweet basil of the variety Genovese Gigante is an economically important crop with common use in the gastronomic, medical and cosmetic fields, to name a few, due to the high content of essential oils (EO). Indoor cultivation is a viable alternative to grow sweet basil all-year-round, independent of the outdoor conditions. READ MORE
