  1. 1. Short-Time Temporal Changes of CH4 Fluxes in Different Tropical Tree Species : In-situ research regarding methane emissions from inundation-adapted Amazonian tree species in Jardim Bot�nico do Rio de Janeiro.

    Kandidat-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :Emelie Athley; [2023]
    Nyckelord :Methane CH4 ; environment; greenhouse gas GHG ; emission; Amazonian tree species; tropical trees; wetland; flux; CH4 emission from plants; tree mediated CH4 emission; Global CH4 budget; environmental stressors; meteorological parameters; natural CH4 emissions;

    Sammanfattning : Methane (CH4) is guaranteed to affect climate change and is essential in rising temperatures. Scientists have known for over two decades that wetlands emit CH4 to such an extent that it affects our climate. Tropical trees that grow in wetlands tend to emit or act as a conduit of CH4, to the extent that it has a negative environmental impact. LÄS MER

  3. 2. Urban Planning for Better Air Quality : A case study of the Low-Traffic Neighbourhoods in London

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

    Författare :Greta Gustafsson; [2022]
    Nyckelord :Low-Traffic Neighbourhoods; London; Green Infrastructure; Urban Planning; Air Pollution;

    Sammanfattning : Air pollution affects the environment negatively, boosts climate change, and is the cause of millions of deaths per year, first and foremost affecting the people living in urban areas. Since the early 20th century, many cities have been planned around cars, which are the main contributors to the bad air quality. LÄS MER

  4. 3. Investigation of Emission Source Heights in FLEXPART 10.02 for the Wildfire in Pedrógão Grande, Portugal, 2017

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Anton Nygren; [2019]
    Nyckelord :wildfire; Pedrógão Grande; structural similarity; SSIM; FLEXPART; MERRA2; CO; emission source height; skogsbränder; Pedrógão Grande; strukturell likhet; SSIM; FLEXPART; MERRA2; CO; utsläppshöjd;

    Sammanfattning : One of the worst wildfires in Portugal in 2017 on June17- 21 started at the central part of Pedrógão Grande and spread fast to the surrounding areas Góis, Pampilhosa da Serra and Arganil. The wildfire took 64 lives and a large smoke plume was observed. LÄS MER

  5. 4. Low-Frequency Noise in InGaAs Nanowire MOSFETs

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Christian Mario Möhle; [2017]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Low-frequency (LF) noise (1/f as well as random telegraph-signal (RTS) noise) measurements were performed on high-performance InGaAs nanowire (NW) metal-oxide-semiconductor field-effect transistors (MOSFETs). 1/f noise measurements at room temperature (RT) show that the dominant noise mechanism is carrier number fluctuations.

  7. 5. Directivity of sound from wind turbines : A study on the horizontal sound radiation pattern from a wind turbine

    Master-uppsats, KTH/MWL Marcus Wallenberg Laboratoriet

    Författare :Manne Friman; [2011]
    Nyckelord :Directivity; wind; turbine; noise;

    Sammanfattning : In the present paper, a study on the directivity of sound from a wind turbine has been conducted. The aim of the study is to investigate the horizontal sound radiation pattern through a field study compared to a noise prediction. LÄS MER
