  1. 1. Off-Grid Solar Energy and Its Impacts on Rural Livelihoods : A Case Study on Tanzania

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för samhällsstudier (SS); Linnéuniversitetet/Institutionen för samhällsstudier (SS)

    Författare :Nike Dahlqvist; Samuel Larsson; [2019]
    Nyckelord :ff-grid energy; rural electrification; sustainable Development; Livelihood; Solar Energy; Tanzania.;

    Sammanfattning : Energy poverty and lack of access to electricity is a global problem which is recognised in the sustainable development goal 7. Today 1.2 billion people live without access to electricity and most of them are situated in Sub-Saharan Africa where biomass still constitutes the main source of energy. LÄS MER

  2. 2. Effekter av klimatförändringar på växtplankton i subarktiska och alpina sjöar

    Kandidat-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Matilda Lundström; [2019]
    Nyckelord :Fosfor; Växtplanktonbiomassa; Diversitet; Oligotrofiering; Temperatur;

    Sammanfattning : The aim of this report was to determine how the climate change affects the ecosystems in alpine and subarctic lakes in Sweden. This was done by analyzing data from environmental monitoring of 14 subarctic and alpine lakes that was part of the national time-series lake monitoring program. LÄS MER

  3. 3. Alternative oxidase respiration in the mycorrhizal fungus Laccaria bicolor

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Hilda Mikaelsson; [2019]
    Nyckelord :L. bicolor; mycel; ektomykorrhiza; cellandning; AOX; alternativt oxidas; cytokromoxidas; cyanid; mycelium; ectomychorriza; respiration; alternative oxidase; cytochrome oxidase; salicylhydroxamic acid; n-propyl gallate; cyanide;

    Sammanfattning : The temperature on Earth is rising, and one of the main drivers is anthropogen-ic greenhouse gases such as carbon dioxide (CO2). The world’s forests act as carbon sinks, binding carbon into their biomass. The net carbon assimilation is determined by the uptake and release of CO2 through the processes of photo-synthesis and respiration. LÄS MER

  4. 4. Biocarbon production from biomass based energy plant forapplication in high-value materials

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :David Söderberg; [2019]
    Nyckelord :;

    Sammanfattning : Natural graphite, a type of carbon, is used in most battery driven electronic devices around the world as it serves as the anode in Li-ion batteries. Since 67\% of global production of graphite originates from a single country the EU has classified it as a critical raw material with a high supply risk. LÄS MER

  5. 5. Möjligheter till ökad driftsäkerhet och kostnadseffektivitet i fjärrvärmenät : En simulerings- och optimeringsstudie på Kalmar Energi

    Master-uppsats, Linköpings universitet/Energisystem; Linköpings universitet/Energisystem

    Författare :Carl Torstensson; Daniel Nordborg; [2019]
    Nyckelord :District Heating; NetSim; Simulation; Optimization; Bypass; Bottleneck; Differential pressure; DH; Fjärrvärme; Förbikoppling; Flaskhals; NetSim; Simulering; Optimering; Differenstryck;

    Sammanfattning : Since district heating is the most common way of space heatingin Sweden, continual improvements of theefficiency of production and distribution of district heating is crucial. The purposeof this report is therefore to, using Kalmar Energi as an example, study how the production and distribution of district heating is affected by introducing a bypass pipeat a critical point in the network, and to investigate howcost efficiency might be achieved.
