1. 1. Stratigraphy and palaeoenvironment of the early Jurassic volcaniclastic strata at Djupadalsmölla, central Skåne, Sweden

   Master-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Per Wahlquist; [2023]
   Nyckelord :volcaniclastic; Djupadalsmölla; CSVP; palynomorphs; early Jurassic; late Pliensbachian; Earth and Environmental Sciences;

   Sammanfattning : From the almost 200 volcanic outcrops in the Central Skåne Volcanic Province (CSVP), only three are of volcaniclastic material. These volcanoclastics, and the transition to the underlying crystalline basement, have been investigated for the first time in a drill core (KBH2) from Djupadalsmölla in order to understand the stra-tigraphy, depositional process, age of deposition, and depositional environment.

3. 2. Flexible Sector Coupling (FSC) of Electrical and Thermal Sectors via Thermal Energy Storage (TES) : A Case Study on Oskarshamn Energi

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Raúl Calvo García; Jose María Marín Arcos; [2023]
   Nyckelord :Flexible sector coupling FSC ; district heating DH ; thermal energy storage TES ; heat pump HP ; capacity optimization; dispatch optimization; open-access tools; Flexibel sektorkoppling; fjärrvärme; termisk energilagring; värmepump; kapacitetsoptimering; leveransoptimering; verktyg med öppen tillgång;

   Sammanfattning : The integration of distributed energy sources and systems is of high relevance for the transition towards a more sustainable energy system. Taking into consideration the  amount of emissions produced by the heating sector, which account for at least half of the energy demand in buildings, district heating systems have the potential to play a key role in the transition, by enabling the integration of various energy sources and provide flexible energy services to the grid.

4. 3. Life Cycle Assessment of a small scale, solar driven HVR water purification system

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Sharang Kolathur; [2022]
   Nyckelord :life cycle assessment; air gap membrane distillation; solar energy; levelized cost; grid operated system; livscykelanalys; luftgapmembrandestillation; solenergi; utjämnade kostnader; nätdrivet system;

   Sammanfattning : Water purification systems have made access to drinking water easier by treating water sources which previously could not be used for drinking. Such systems however require energy and materials to build and operate which means they have environmental impacts. LÄS MER

5. 4. PlaCo : The plastic collecting robot

   Kandidat-uppsats, KTH/Mekatronik

   Författare :Annie Persson; Johanna Bergsten; [2021]
   Nyckelord :Arduino; IR-sensor; marine debris; mechatronics; microplastics; ultrasonic sensor; Arduino; IR-sensor; marin nedskräpning; mekatronik; mikroplaster; ultraljudssensor;

   Sammanfattning : The oceans are an essential global resource for all living organisms but especially for us humans. However, year after year we continue to neglect proper recycling of our waste, resulting in litter ending up in our oceans. The majority of said litter comes from single use plastic items. LÄS MER

7. 5. En minskad plastkonsumtion? - En studie om konsumenters attityder och förväntade respons på införandet av skatten på plastbärkassar i Sverige

   Kandidat-uppsats, Malmö universitet/Fakulteten för kultur och samhälle (KS)

   Författare :Sebastian Segge; Tina Rodjeil; [2020]

   Sammanfattning : Plastmaterial har sedan 1950-talet orsakat problem i naturen på grund av materialets slitstarka och svårnedbrytbara egenskaper. Dessa egenskaper är också en anledning till dess popularitet, och varje år tillförs ungefär 100 miljarder plastbärkassar bara till den europeiska marknaden. LÄS MER
