  2. 12. Volatile fatty acid production from co-fermentation of primary sludge and food waste without pH control

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Binyam Bedaso; [2019]
    Keywords : Volatile fatty acid; Co-fermentation; Primary sludge; Food waste;

    Abstract : The production of volatile fatty acids (VFAs) from waste stream is gaining high attention because of their high market value and wide range of applications. In this study, the production of VFA from co-fermentation of primary sludge from wastewater treatment plant and food waste without pH control was evaluated using a pilot-scale reactor in a semi-continuous mode of operation.

    Author : Ellinor Jakobsson; [2019]
    Keywords : Macroinvertebrates; Arctic; seasonality; community composition; Abisko;

    Abstract : Arctic ecosystems are amongst the most vulnerable on Earth to ongoing climate change. While the responses to these changes are well studied on land, less is known about how aquatic communities may respond to a warmer arctic. READ MORE

  4. 14. Reindeer induced changes in vegetation composition and plant traits on a tundra-forest border

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Femke Pijcke; [2019]
    Keywords : physical geography; ecosystem analysis; plant functional traits; nutrient allocation; grazing; reindeer; Earth and Environmental Sciences;

    Abstract : Reindeer (Rangifer tarandus) are the most common large herbivores in the arctic. With a habitat spreading over the entire circumpolar region, they can have a substantial effect on plant species composition and ecosystem processes and functions. READ MORE

  5. 15. Lignosers vintervärden i gestaltningar : bark, habitus och placering

    University essay from SLU/Department of Landscape Architecture, Planning and Management (from 130101)
