1. 21. Assessing Saudi Arabia's Vision 2030: Economic Diversification, Social Inclusion, and Environmental Preservation through the Triple Bottom Line Lens

   Kandidat-uppsats, Linnéuniversitetet/Institutionen för statsvetenskap (ST)

   Författare :Zara Salman; [2024]
   Nyckelord :Sustainable development; Saudi Arabia; National Interest; Economic reformation; Vision 2030; Agenda 2030; Triple Bottom Line Theory.;

   Sammanfattning : This essay critically analyzes the implementation of Saudi Arabia's Vision 2030 initiative through a detailed descriptive case study as the methodological framework, employing the Triple Bottom Line (TBL) model as the theoretical basis. The essay delves into the alignment of Vision 2030 with TBL principles, particularly in its influence on economic diversification, social inclusivity, and environmental conservation. LÄS MER

3. 22. Generation and detection of entangled single-photon pairs

   Kandidat-uppsats, Uppsala universitet/FREIA

   Författare :Gabriella Tesfamichael Habtezion; [2024]
   Nyckelord :;

   Sammanfattning : Quantum information technology is an emerging field with important applications such as quantum cryptography and teleportation, quantum imaging and lithography. These applications make use of single photons and pairs of entangled photons. In this work, we experimentally generate and attempt to detect the entangled photons. LÄS MER

4. 23. Headfirst into shallow water - Wetland restoration and its contribution to the Habitats Directive

   Master-uppsats, Uppsala universitet/Växtekologi och evolution; Uppsala universitet/Institutionen för biologisk grundutbildning

   Författare :Elin Brandt Korall; [2024]
   Nyckelord :Wetlands; GIS; Restoration; Rewetting; Ecology; LONA; Habitats Directive; Natura 2000; Nature conservation; Våtmarker; GIS; Geografiska informationssystem; Restaurering; Återvätning; LONA; Art- och Habitatsdirektivet; Natura 2000; Naturvård;

   Sammanfattning : Located in the borderland between aquatic and terrestrial environments, the wetlands cover a wide spectrum of habitats and enable living standards for a great variety of organisms. Although important habitats, a great extent of the original wetlands have disappeared in Europe and Sweden due to anthropogenic disturbances. LÄS MER

5. 24. Cleaning methods for removal of bound soiling on leather

   Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

   Författare :Olivia Cati Starck; [2023-11-14]
   Nyckelord :Conservation; Leather; Cleaning; Vulpex; White spirit; Isopropanol; Gellan gum gel;

   Sammanfattning : This thesis investigates the removal of bound soiling on leather using three cleaning methods: Vulpex (10%) in white spirit, gellan gum gel loaded in isopropanol and white spirit by itself. More detailed studies of cleaning methods for bound soiling in leather conservation are sparse. LÄS MER

7. 25. Nya metoder för fernissaborttagning – En komparativ studie

   Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

   Författare :Alica Larsson; [2023-11-08]
   Nyckelord :Oil painting; Varnish removal; Evolon® CR; Tissue-gel composite;

   Sammanfattning : In recent years, new varnish removal methods have emerged in conservation, with two notable approaches: the tissue-gel composite method, involving gel-coated tissue material pressed onto varnished surfaces for simultaneous dissolution and binding, and the use of Evolon® CR textile saturated with solvent. Evolon® CR offers an alternative to gels and tissue-gel composites, aiming to eliminate residue from gel thickening agents and the need for mechanical cleaning, while enabling the use of non-polar solvents in a bound form.
