  1. 1. Bluegreengrey (BGG) solution for future climate and flood-resilient urban drainage network by enhancing the natural hydrological cycle

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Adnan Asif Rifat; [2023]
    Nyckelord :Bluegreengrey; Sustainable stormwater; Basement flooding; Urban flooding; Pipe Network; BGG; Climate change; Hydrology; Mike .; Technology and Engineering;

    Sammanfattning : A loop of urbanization, increasing impervious surface in urban areas, increasing temperature, rainfall, surface runoff and flooding, and lack of new spaces have been adding challenges to urban drainage systems for decades. The climate change impacts are exposing the existing vulnerable conventional urban drainage systems to more challenges in the future. LÄS MER

  3. 2. Thermal Investigation of the Green Revolution Energy Converter : A study on the heat transfer within the GREC in regards of temperature distribution and heat rate

    L3-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Wilma Fager; Maja Abrahamsson Bolstad; Emma Gustafsson; Emma Andersson; Matilda Eriksson; [2023]
    Nyckelord :GREC; Energy; Heat transfer; Heat rate; Temperature distribution;

    Sammanfattning : To reduce emissions, new technological solutions can be of use. One technology which is currently being developed is the Green Revolution Energy Converter, GREC. GREC is an engine with the aim to produce electricity from temperature gradients.  This project is part of a greater project that is divided in two with different focus areas. LÄS MER

  4. 3. Biogas Potential in the North of Sweden : Inventory and Techno-Economic Assessment of Substrates for an Increased Biogas Production in Norrbotten

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Alma Fahlén Hammar; [2023]
    Nyckelord :Biogas; anaerobic digestion; AD; Norrland; bioenergy; fossil-free; chemical engineering; Chemistry; Technology and Engineering;

    Sammanfattning : Great investments are planned in the north of Sweden the coming years, not the least in the county of Norrbotten where the projects collectively are referred to as the green transition due to the focus on fossil-free techniques. But to be able to secure a sustainable energy supply and reach the goal set by the member states of the European Union of a carbon dioxide neutral union in 2050 the production of alternative energy sources needs to intensify.

  5. 4. Building with pollution

    Master-uppsats, Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Zornitsa Hristova Kovacheva; [2021]
    Nyckelord :Arts and Architecture;

    Sammanfattning : Black carbon is an ever-growing global problem and one of the most important environmental issues of this generation. Black carbon, also known as soot, is a highly polluting substance and it is the second-largest polluter after carbon dioxide. LÄS MER

  7. 5. Secondary aerosol formation from dimethyl sulfide - Smog chamber experiments and detailed process modelling

    Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Dana Lüdemann; [2020]
    Nyckelord :aerosol modelling; atmospheric physics and chemistry; marine aerosols; ADCHAM; aerosol; dimethyl sulfide; Physics and Astronomy;

    Sammanfattning : The aim of this thesis was to investigate the secondary aerosol formation from dimethylsulfide (DMS) using the aerosol dynamics, gas- and particle-phase chemistry kinetic multi-layer model, ADCHAM. The first simulations, concerning the butanol oxidation via hydroxyl radicals (OH), were performed to characterize the UV-light source of the AURA smog chamber (Aarhus university, Denmark), later used for the DMS experiments.
