   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HFMI; TIG-dressing; Life extension; Post weld treatment; Gain factor; Linear elastic fracture mechanics; Crack retrofiting; Peening; fatigue crack; Crack detection; Microhardness; Concentration factor; LEFM; TIG-remelting; Strain gauge;

   Sammanfattning : This thesis investigates the performance of improved welds with two post-weld treatment methods for application on existing structures. High-Frequency Mechanical Impact (HFMI) treatment and Tungsten Inert Gas (TIG) remelting were used for fatigue life extension of welded structures. LÄS MER

4. 3. Bifunctional ADAPTs: Opportunity for serological Half-life extension and Targeted therapy

   Författare :Andreas Wisniewski; Sophia Hober; Masood Kamali-Moghaddam; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ABD; ADAPT; Autoimmune diseases; Cancer; Half-life extension; HRP; Phage Display; Protein Engineering; Targeted therapy; Biotechnology; Bioteknologi;

   Sammanfattning : Small engineered scaffold proteins (ESPs) gain more and more popularity as biological drugs, due to their specificity and applicability in diagnostics and therapy. Thanks to their high stability, low immunogenicity and low production cost, they present themselves as a promising alternative to the market-leading antibodies. LÄS MER

5. 4. Circular Business Models for Electric Vehicle Battery Second Life : Challenges, enablers, and preconditions from an ecosystem perspective

   Författare :Reza Toorajipour; Koteshwar Chirumalla; Fredrik Wallin; Vinit Parida; Patricia Van Loon; Mälardalens universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric vehicle battery second life; circular business models; ecosystem; electric vehicles; EV batteries; circular business model innovation; circular economy; preconditions; second life configurations; battery second life; Innovation and Design; innovation och design;

   Sammanfattning : Sustainability has become a critical issue due to global warming, scarcity of resources, and the high costs of raw materials. It is vital to reconsider linear business models and value creation processes and transition towards circularity. The growth of the electric vehicles market is promising; however, it comes with a major downside. LÄS MER

7. 5. Age-specific trade-offs in life-history evolution

   Författare :Martyna K. Zwoinska; Alexei Maklakov; Marjo Saastamoinen; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; life history; trade-off; learning; aging; sex differences; dispersal; Caenorhabditis; Drosophila; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

   Sammanfattning : Trade-offs prevent selection from driving all fitness-enhancing traits towards values that would maximize fitness. Life-history trade-offs, such as the one between survival and reproduction are well-studied, yet trade-offs can also involve behavioural or cognitive traits. LÄS MER
