  1. 6. Low-Temperature Thermal Control System for an Environmental Chamber

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Aleksis Pauls Lindemanis; [2022]
    Nyckelord :Space simulator; environmental chamber; thermal control design; thermal conductivity in bolted joints; thermal simulations; Mars climate; Carbon dioxide sublimation and deposition;

    Sammanfattning : In spite of significant reduction of cost associated with launching a spacecraft, launching deep space exploratory missions are yet to be accessible to most universities and researchers. A solution to testing scientific hypotheses and verifying technologies for space is the use of environmental chambers, also know as space simulators, - vacuum chambers, which replicate the space environment.

  3. 7. Methane and Carbon Dioxide Emissions From Three Smallscale Hydropower Stations in South of Sweden

    M1-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :Edevardt Johan Danielsen; Alexandra Jonsson Valderrama; [2022]
    Nyckelord :Hydropower; Reservoir; Freshwater; automated Flux chambers; Emissions; Ebullition; Diffusion; Greenhouse gases; GHGs; Methane; CH4; Carbon dioxide; CO2; Dissolved oxygen; DO; Variability; Spatial; Temporal; Dissolved inorganic carbon.; Vattenkraft; Reservoar; Sötvatten; automatiserade Fluxkammare; Utsläpp; Ebullition; Diffusion; Växthusgaser; GHHs; Metan; CH4; Koldioxid; CO2; Löst syre; DO; Variabilitet; Rumslig; Temporal; Löst oorganiskt kol.;

    Sammanfattning : Over the past decades, evidence show that the anthropogenetic greenhouse gases (GHG) emissions of carbon dioxide (CO₂) and methane (CH₄) are the main drivers behind global warming and are becoming stronger. Globally, hydropower is among the main sources of renewable energy and the popular notion that hydropower electricity is carbon neutral has been under debate as evidence from measurements in different regions of the globe show significant and highly variable carbon emissions from hydropower reservoirs.

  4. 8. Greenhouse gas emissions from three large lakes during the autumn 2020

    Kandidat-uppsats, Linköpings universitet/Institutionen för tema

    Författare :Veronica Bohlin; Anja Anderö Nordqvist; [2021]
    Nyckelord :methane; carbon dioxide; dissolved inorganic carbon; pCO2; flux chambers; large lakes; methane budget; carbon budget; GHGs; freshwater; spatiotemporal; ebullition; diffusion; autumn; metan; koldioxid; upplöst oorganiskt kol; pCO2; kammarmetod; stora sjöar; metanbudget; koldioxidbudget; växthusgaser; sötvatten; spatiotemporal; ebullition; diffusion; höst;

    Sammanfattning : Methane (CH4) and carbon dioxide (CO2) are two greenhouse gases and main drivers of global climate change. Lakes are known to be a source of CH4 and CO2 to the atmosphere. While the importance of these emissions is clear, their magnitudes and regulation are still uncertain due to the scarcity of flux measurement data from lakes. LÄS MER

  5. 9. KOLDIOXIDBUDGET FÖR LYCKSELE KOMMUN : En studie över koldioxidutsläppet i kommunen och hur snabbt det ska åtgärdas

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Julia Lundquist; [2021]
    Nyckelord :Koldioxidbudget; koldioxidekvivalenter; koldioxidutsläpp; konsumtionsutsläpp; nedtrappning; växthusgasutsläpp.;

    Sammanfattning : The Earth is getting warmer at an alarming rate. The cause for the increase in temperature is predominantly anthropogenic emissions. Sweden’s territorial greenhouse gas emissions was 50,9 million tons CO2e in 2019, emissions from forestry and consumption not included. LÄS MER

  7. 10. The future of agriculture : Creating conditions for a more sustainable agriculture sector with the help of data and connectivity

    Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Märta Ernfors; [2021]
    Nyckelord :Agriculture; Arable Farming; Digital Agriculture; Digital Farming; Sustainability; Food Production; 5G; Data; Data Sharing; Big Data; Jordbruk; Odling; Uppkopplat Jordbruk; Hållbarhet; Livsmedelsproduktion; 5G; Data; Datadelning;

    Sammanfattning : The food production rate is required to increase in order to meet the ever-increasing world population. At the same time, this needs to be done in a sustainable manner as the agriculture sector today is responsible for a substantial part of the annual carbon dioxide emissions associated with human activities.
