   Författare :Johanna Forsvall; [2021]
   Nyckelord :Kombucha; Kombucha culture; Fermentation; Food engineering; Technology and Engineering;

   Sammanfattning : The fermented tea beverage kombucha is a traditional drink that has been consumed for thousands of years in Asia. Over the past decades, it has gained greatly in popularity amongst consumers and researchers also in the rest of the world. LÄS MER

3. 17. 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

4. 18. Influences of black carbon levels in the micro-environment inside urban buses

   Kandidat-uppsats, Stockholms universitet/Institutionen för miljövetenskap

   Författare :Anton Dahlberg; [2020]
   Nyckelord :Black carbon; buses; in-cabin; urban air pollution;

   Sammanfattning : Several studies indicate that the cabin of buses is the micro-environment in urban public transport where commuters might be the most exposed to black carbon. Black carbon functions as an indicator of air pollution, which is shown to have harmful impacts on the human body and because it may lead to cancers, systemic inflammation, and cardiovascular diseases, it is listed as one of the top causes to premature deaths, globally.

5. 19. Planetary boundary layer height measurements in a rural environment in southern Sweden - Relation to meteorological parameters and aerosol particle concentrations

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

   Författare :Ellen Carneheim; [2020]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : The aim of this project is to analyse planetary boundary layer height (BLH) measurements from the Hyltemossa research station and find their dependence on seasonality, time of day, and air temperature. Further, investigation was made into the correlation between mass concentration of particulate matter with equivalent diameter... LÄS MER

7. 20. Modified lignin as replacement of carbon black in elastomers- For the development of sustainable tyre technology : The substitution of carbon black with modified lignin- Green tyre technology

   Master-uppsats, Karlstads universitet/Avdelningen för kemiteknik

   Författare :Mostafa Ahmed Ismail; [2020]
   Nyckelord :lignin; tyre rubber; elastomeric materials; esterfication;

   Sammanfattning : Due to its large flexibility, low-price, large availability, and properties lignin is seen as an important compound with a wide range of applications. The increasing demand of fossil-based rubber materials is causing a serious threat to the environment and it is contributing to plastic- and marine pollution, ozone depletion and carbon dioxide emission (CO2) [1,2].
