We determined the concentration of markers in cartilage and synovium metabolism in the synovial fluid (SF) of the knee of young beagle dogs with slowly progressive osteoarthrosis. Osteoarthrosis (OA) was induced by a tibial 30°valgus osteotomy to the right hindlimb of 16 dogs. The contralateral knee served as control. The animals were killed 7 (group I) and 18 months (group II) after operation. Th
Instead of investing 145 billion SEK in building a new high speed rail network, much greater value in terms of transport capacity is likely to be found in constructing a new system of tube transport with a travel speed of 600 km/h. The suggested technology does not exist yet. However, research and development is advancing and accepting that a new technology is emerging might be the greatest hurdle
This thesis outlines the design and construction of an acoustophoretic trapping device with greatly increased capacity and throughput, compared to current commercial systems. In acoustic trapping, a strong, localised acoustic field is generated inside a channel. This field can capture and retain particles against a flow, allowing for nanoparticle purification and enrichment without the need for ul
Many premature deaths and health problems could be prevented by adhering to a healthy diet, however, many people lack the self-regulation needed for maintaining healthy behaviors. Goal-conflicting situations (i.e., when a person needs to decide between one of two conflicting goals) are an obstacle for self-regulation, while coping planning is found to be useful in these situations since it entails
This paper evaluates whether a deep reinforcement learning (DRL) approach can be implemented, on the Swedish stock market, to optimize a portfolio. The objective is to create and train two DRL algorithms that can construct portfolios that will be benchmarked against the market portfolio, tracking OMXS30, and the two conventional methods, the naive portfolio, and minimum variance portfolio. We eval
The Alps are undergoing constant landscape changes due to modern socio economic changes. Especially grassland ecosystems of alpine meadows and pastures are threatened by the slow abandonment of the alpine transhumance traditions. This influences not only biodiversity but also the important cultural landscape seen as a valuable heritage in the Alps. The landscape in the North Italian alpine provinc
Fed aquaculture is a necessary practice to meet the seafood requirements of a growing population in a sustainable manner. There is a high demand for fish feed to meet the rising protein requirements of the industry. Currently, fish feeds are either unsustainable, affected by seasonal variations, lack a complete amino acid profile, lack scalability, or are too expensive. Single Cell Protein (SCP) i

Applied Machine Learning in Steel Industry – Examination of possible applications of machine learning for SSAB Oxelösund In modern industry there are high demands for increased resource efficiency that in part are motivated by the stronger competition on the global market, as well as by the societal necessity for a more sustainable industry. This master thesis project examines applied machine lear
On the 30th-31st of January 2015 a cultural event took place at the concert and congress house of Uppsala in mid-Sweden; Uppsala Konsert & Kongress. The event was called "Irländskt!" (i.e. "Irish!") and consisted of concerts, workshops and sessions. This is a sociological study of the Irish traditional sessions at this event. The participants were studied as part of a commu
Children who are placed in foster care because of neglect or abuse have the right to maintain the relationship with their parents, as per the Swedish LVU law, though this is more often than not a complex feat to achieve. The Convention on the Rights of the Child states that children who are capable of forming their views shall be given the right to express those views freely in all matters affecti
Title: Adaptation of shipment consolidation and distribution network design to omni-channel retailing Authors: Johan Deniz, Martin Månsson Supervisor: Joakim Kembro, Department of Industrial Management and Logistics, Faculty of Engineering, Lund University Problem description: Global retailers tend to have complex distribution networks. A part of the complexity stems from trade-offs in deciding
Purpose: The purpose of this study is to explore how consumers navigate and justify their consumption habits while striving for a more sustainable identity. The study examines the internal dilemmas that arise when sustainable values confront the realities of identity expression and social influence. Methodology: A qualitative research approach was adopted, in the form of in-depth interviews, invo
Entrepreneurial intentions have been identified as a relevant precursor to entrepreneurial behavior; however, the complexities of entrepreneurial intention remain under-explored. This study examines the impact of offspring involvement with parental businesses on their entrepreneurial career intentions and the indirect roles of perceived desirability and perceived feasibility. Building primarily on
Bioelectronics holds great potential as therapeutics, but introducing conductive structures within the body poses great challenges. While implanted rigid and substrate-bound electrodes often result in inflammation and scarring in vivo, they outperform the in situ-formed, more biocompatible electrodes by providing superior control over electrode geometry. For example, one of the most researched met
Solar-driven photocatalytic green hydrogen (H2) evolution reaction presents a promising route toward solar-to-chemical fuel conversion. However, its efficiency has been hindered by the desynchronization of fast photogenerated charge carriers and slow surface reaction kinetics. This work introduces a paradigm shift in photocatalyst design by focusing on the synchronization of charge transport and s
Design thinking is an innovative methodology that may be applied by small and medium enterprises which emphasizes a human-centered approach to problem-solving, facilitating the creation of novel solutions for complex and open-ended challenges like the development of new products. Despite its recognized importance in business and academia, many industrial SMEs struggle with applying design thinking
Ageing societies are facing major housing challenges. Understanding and addressing older adults' diverse housing needs and preferences are crucial. Having access to suitable and sustainable housing options can improve social cohesion, independence, health, and well-being. Participatory processes in housing development can enhance inclusion and democratic participation. This study uses Ramlösa Port
Background: Deposition of tau aggregates is a pathological hallmark of Alzheimer's disease that is closely linked both spatially and temporally to emergence of neurodegeneration and manifestation of clinical symptoms. There is an urgent need for accurate PET, CSF, and plasma biomarkers of tau pathology to improve the diagnostic process in clinical practice and the selection of participants and mon
