  1. 11. Exploring the physiological variables of oxygen isotope composition in chondrychthyan teeth

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning; Uppsala universitet/Institutionen för organismbiologi; Uppsala universitet/Evolutionsbiologi

    Author : Carlos Oliveira; [2019]
    Keywords : chondrichthyan; oxygen; isotope; fractionation; teeth; enameloid; dentine;

    Abstract : Since the discoveries of vertebrate bioapatite’s ability to record oxygen isotopecomposition of ambient seawater were made (Kolodny, 1983), oxygen isotopes have beenwidely used as a climatic and oceanographic proxy. The δ18OP aquatic vertebrate apatite isa function of the δ18Ow value of the ambient water, yet “vital effects” on the δ18OP compositionhave been reported previously (Venneman et al. READ MORE

  3. 12. Soil organic carbon storage, distribution and characteristics in two contrasting permafrostaffected environments : Evaluating the role of alpine and lowland tundra areas in the permafrost carbon feedback

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Didac Pascual; [2018]
    Keywords : soil organic carbon; permafrost; tundra; alpine; climate change; feedback; mapping; landcover; landform;

    Abstract : An important portion of the large northern permafrost soil organic carbon (SOC) pool might be released into the atmosphere as greenhouse gases following permafrost thawing and subsequent SOC decomposition under future warming conditions, resulting in a warming amplification known as the permafrost carbon feedback. Improved knowledge about the amount, composition and distribution of the permafrost SOC pool is essential when assessing the potential magnitude and timing of the permafrost carbon feedback.

  4. 13. Production, sorption and pathways for dissolved organic carbon flow in the Krycklan catchment. : Modelling with focus on the terrestrial forest ecosystem.

    University essay from KTH/Mark- och vattenteknik

    Author : Francisco Mieres Dinamarca; [2016]
    Keywords : Dissolved Organic Carbon; Modelling; Krycklan Catchment;

    Abstract : Dissolved Organic Carbon accounts for many different functions in the boreal forest ecosystem. It is the main vehicle for organic carbon transport from the litterfall to the forest soil profile and together with water drainage it can be transported to streams. READ MORE

  5. 14. The power of suggestion on consumers´preferences for organic produce

    University essay from Göteborgs universitet/Institutionen för nationalekonomi med statistik

    Author : Amanda Sundberg; [2015-07-03]
    Keywords : ;

    Abstract : Conventional production of fruits and vegetables entail the use of pesticides and other poisonous chemicals. Producers use these poisonous chemicals in order to make the crops more profitable by for example making them more resistant to insects, in order to acquire a faster growth rate or to obtain larger crops.

  6. 15. Wastewater to renewable energy at a tapioca factory in Vietnam

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Anna Gustafsson; [2015]
    Keywords : Vietnam; biogas; tapioca; cassava; anaerobic digestion; wastewater treatment; minor field study; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Chemistry;

    Abstract : Anaerobic digestion is a cost-effective way of treating high organic content wastewater, as it efficiently removes large amounts of organics at the same time as biogas is produced. The production of starch from cassava roots, named tapioca, creates large amounts of high organic content wastewater and uses large amounts of thermal energy for drying the starch. READ MORE
