1. 1. CSR communication and the use of recycled synthetic fibres in the fashion industry: A content analysis study of two Swedish fashion brands

   Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning; Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

   Författare :Linn Löfling; [2023]
   Nyckelord :recycled synthetic fibres; fast fashion; slow fashion; CSR communication; Earth and Environmental Sciences;

   Sammanfattning : The fashion industry is one of the largest contributors to environmental issues and has a significant part of plastic production due to the use of synthetic fibres. Much scientific research indicates that the fast fashion model is a significant part of using synthetic fibres; however, slow fashion brands are also using the fibres. LÄS MER

3. 2. Finding ways of optimizing coagulant dosage, for a more sustainable wastewater treatment process

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Hanna Sjöman; [2023]
   Nyckelord :Wastewater treatment process; coagulant dosage; COD; machine learning; water and environmental engineering; Technology and Engineering;

   Sammanfattning : The wastewater treatment process at Oatly consists of several treatment steps of which, two are chemical treatment steps involving coagulation followed by flotation to remove phosphorous and COD. The coagulant dosage is mainly determined based on the operator’s experience and supported using results from jar tests. LÄS MER

4. 3. Exploring GPT models as biomedical knowledge bases : By evaluating prompt methods for extracting information from language models pre-trained on scientific articles

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Ebba Hellberg; [2023]
   Nyckelord :Language model; GPT; knowledge probing; information extraction; prompt methods; Språkmodell; GPT; kunskapsbas; informationsextraktion; prompt-metoder;

   Sammanfattning : Scientific findings recorded in literature help continuously guide scientific advancements, but manual approaches to accessing that knowledge are insufficient due to the sheer quantity of information and data available. Although pre-trained language models are being explored for their utility as knowledge bases and structured data repositories, there is a lack of research for this application in the biomedical domain.

5. 4. In-plane Wetting in Packaging Material and its Consequences for Cap Performance

   Master-uppsats, Lunds universitet/Centrum för analys och syntes

   Författare :Ellinor Carolina Salomonsson; [2023]
   Nyckelord :Tetra Pak®; Aseptic; Paperboard; Pre-laminated hole; Edge wicking; In-plane wetting; Hydrogen peroxide; Cap detachment; Polymer technology; Technology and Engineering;

   Sammanfattning : Aseptic packaging solutions enable long time storage without refrigeration and are an important part of securing food supply globally. The package material consists of multiple layers: A paperboard for robustness, polymers for adhesion as well as shielding the board from liquid, and a barrier protecting the product. LÄS MER

7. 5. Manufacturing & Regional Cost Competitiveness of Commercial Sodium Ion Cells : A bottom-up cost analysis of Lithium and Sodium Ion Battery Storage

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

   Författare :Srujan Kiran Alva; [2023]
   Nyckelord :Sodium Prussian Blue Analogues; Sodium layered oxides; Lithium Iron Phosphate; Sodium NMC111; Lithium NMC111; Battery Manufacturing Scaling; Cost Analysis; Battery manufacturing policy; Industrial Import Costs; Cathode Thickness;

   Sammanfattning : Batteries are increasingly seen as an indispensable element in the rapid progress of the energy transition. With forecasts for global demand set to reach 2 TWh by 2030 and increasing policy support for battery manufacturers, many questions arise on whether the current rapid expansion of battery manufacturing industry is sustainable.
