  1. 1. Something in the Air: Fetal air pollution exposure and long-run labour outcomes: Evidence from Germany.

    Master-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Johanna Lidman; [2023]
    Nyckelord :Fetal origins hypothesis; Air pollution; Avoidance behavior; Human capital; Sibling comparisons; Business and Economics;

    Sammanfattning : This study examines the long-run impact of air pollution exposure at the month of birth and during pregnancy on labour outcomes in Germany. I match air pollution levels on a federal-state level to a longitudinal survey sample on individuals born in Germany. LÄS MER

  3. 2. Effects of stratospheric wildfire smoke on ozone depleting substances and ozone levels in the northern midlatitudes

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

    Författare :Christopher Grüner; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The goal of this project was to examine whether there are correlations between recent wildfires in the northern hemisphere and stratospheric ozone anomalies in the midlatitudes following the creation of ozone depleting substances. To achieve this goal, data from the Aura satellite's Microwave Limb Sounder instrument was used and processed with self-written Python scripts. LÄS MER

  4. 3. Investigation of Methods to Improve PZT Sol-Gel Deposition Process for Energy Harvesting Applications

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Mikael Granberg; [2022]
    Nyckelord :PZT; sol-gel; self-polarization; seed layer; titanium oxidation; PZT; sol-gel; självpolarisering; seedlager; titanoxidering;

    Sammanfattning : The purpose of this work was to investigate ways to modify Silex sol-gel deposition of PZT (PbZrxTi(1-x)O3, Lead Zirconate Titanate) in order to improve its properties for energy harvesting applications. A number of methods to improve the figure of merit for energy harvesting (FOM= e312/ε), cause self-polarization, increase lifetime, reduce cost, increase throughput or simplify processing were tested.

  5. 4. Implementing spatial variance in the rate of photolytic breakdown of NO2 in urban street canyons

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Fabian Friberg; [2022]
    Nyckelord :cfd; computational fluid dynamics; NOx; street canyon; NO2; NO; O3; photolysis; OpenFOAM; Physics and Astronomy;

    Sammanfattning : In this study a module for calculating the solar exposure of individual fluid cells was developed to more accurately represent the effect of photolysis on the pollutant dispersion in an urban street canyon. The module was tested and validated on 12 different cases, each with a different geographical location, time of year and/or time of day. LÄS MER

  7. 5. Qualitative analysis of a regional public policy for air quality : A case study of Normandie, France

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

    Författare :Arthur Avenas; [2021]
    Nyckelord :Atmospheric pollution; Atmosphere Protection Plan; policy planning; legislation; incentive measures; best practices; reduction of emissions; regional scale; case study; Normandie;

    Sammanfattning : Today, outdoor air quality occupies an important place into civic dialogue because of the many impacts of atmospheric pollution on health. Different legislations and strategies have thus been implemented across the world to improve outdoor air quality. LÄS MER
