  3. 2. Response of foraminifera Ammonia confertitesta (T6) to ocean acidification, warming, and deoxygenation - An experimental approach

    University essay from Lunds universitet/Geologiska institutionen

    Author : Elsa Muller; [2023]
    Keywords : Acidification; Warming; Deoxygenation; Foraminifera; Ammonia confertitesta T6 ; Culture Experiment; Trace elements; Earth and Environmental Sciences;

    Abstract : Ocean acidification, warmer temperatures, and the expansion of hypoxic zones in coastal areas are direct consequences of the increase in anthropogenic activities. However, so far, the combined effects of these stressors on calcium carbonate-secreting marine microorganisms - foraminifera are complex and poorly understood. READ MORE

  4. 3. Life after social death : A study of creolisation among enslaved communities in the former Danish West Indies

  6. 5. Space Heat Power Demand for Existing Buildings : Feasibility, Improvement-Measures, and Impact on Climate Performance Using a Swedish Multi-Dwelling Building as Case Study

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Andreas Holmén; [2022]
    Keywords : ;

    Abstract : The most commonly used indicators of energy performance of existing buildings in Sweden, Specific Energy Use (SEU) and Primary Energy Use (PEU), are very rough measures that does not account for short term effects and therefore they are not necessarily well suited to evaluate climate performance of existing buildings. In this thesis the similar but slightly different indicators Miljöbyggnad Heat Power Demand (MHPD) (Värmeeffektbehov in Swedish) and Feby Heat Loss Number (FHLN) (Värmeförlusttal in Swedish), both indicators of Space Heat Power Demand (SHPD), has been evaluated as complementary indicators to SEU and PEU.
