Biofilms in the dairy and food industry, particularly those formed by Bacillus subtilis, present significant contamination and food safety challenges. This thesis investigates the impact of stainless steel surface properties, specifically oxide layer formation and surface roughness of polished coupons, on biofilm development. Bacillus subtilis SA 22 (NCA 72-52; DSM 4181) was cultivated using a CDC

This thesis explores the architectural potential of compressed wool as a natural material capable of forming complex structures. From the beginning, the project combined two main directions: first, the exploration of natural, growth-based patterns such as differential growth and hyperbolic surfaces, and second, the investigation of material behavior through direct experimentation. These two paths

Ett samtal om serieteckningar som ett sätt att nå ut med angelägen forskning mellan Robert Nyberg, Tecknare och Semra Sahin Haglund, Doktorand Mittuniversitetet/Lunds universitet.. Det handlar om normer inom bäckenbottenhälsa, urinläckage och bemötande i vårdenA conversation about cartoons as a way to reach out with important research between Robert Nyberg, artist, och Semra Sahin Haglund, phd student, Mid Sweden University/Lund University. It's about norms in pelvic floor health, urinary leakage, and treatment in healthcare.

Overfishing poses a critical threat to marine ecosystems and local coastal communities worldwide. Designation of Marine Protected Areas, particularly those incorporating No-Fishing Zones, act as refuges from the effects of climate and fishing, serve as valuable biodiversity conservation tools for more resilient social-ecological systems. Nevertheless, to be successful in long-term conservation the

Bakgrund: Det är ett välkänt faktum att den demografiska utvecklingen kommer att kräva nya arbetssätt för att äldre ska kunna få vård i liknande omfattning som tidigare. Förhoppningen har ställts till införandet av välfärdsteknik som en viktig del av kompetensförsörjningen, inte bara för att den kan bidra till att upprätthålla välfärden trots fler äldre, utan också genom att göra äldreomsorgsarbet

In this thesis work, the design challenges of building a robust Battery Management System with the existing solutions are discussed highlighting the communication within the battery pack. The initial plan of this master thesis work was to investigate wireless BMS technologies and to implement a wireless BMS, as a demo prototype for three segments with wired BMS for a full 7.2 kWh battery pack. Aft

Triangulerade kategorier, och i synnerhet tensortriangulerade kategorier, uppstår inom en mängd områden inom matematiken. Därför blir de viktiga objekt som studeras i sin egen rätt. Vanligtvis är man intresserad av att klassificera olika underkategorier, särskilt tjocka eller lokaliserande underkategorier, av triangulerade kategorier. Tyvärr kan det oftast vara svårt att göra detta. Dessutom kan tWe provide an introduction to the theory of tensor triangular geometry. In particular sufficient foundations from the theory of triangulated categories are introduced so as to be able to cover the theory of geometry for essentially small tensor triangulated categories, and to cover a theory of tensor actions, with corresponding geometric notions, for rigidly compactly generated tensor triangulated

This study aims to understand and contribute to the general knowledge of the experiences and perceptions of social services officials working in the public social service sector in a relatively small municipality in Southern Sweden, regarding changes made to the workflow as a consequence of reorganization within the unit for adult care initiatives. This premise provides a good overview of the char

In today's society, drugs have a negative connotation that often results in negative responses towards those with drug use drugs from the surrounding environment. Stigma is a concept strongly related to those who suffer from addiction, and often, the close relatives of these individuals experience this stigma as well. Anonymous online forums have created a safe space where people who experienc

Feedback är den mest effektiva strategi en lärare kan använda sig av i undervisningen. Särskilt inom matematiken där elevers prestationer har sjunkit i åratal. I skolan ska elever dock utveckla inte bara ämneskunskaper utan även de sociala regler, normer och som personer. Genom fallstudie granskas hur tre lärare använder sig av feedback och elevernas upplevelser. Detta resulterar i huvudsakligen ä

Sustainable transport is an important piece of the sustainable city puzzle. Ways of traveling locally and internationally must become more sustainable. Although, a lot of transport today is not sustainable. The visions and guidelines that promote sustainable transport must also make concreate solutions in the transport networks that people can switch to and want to use. By conducting a critical co

This paper aims to analyse the oral communication patterns amongst upper secondary school students within the subject of math. To this end, Mohan’s Knowledge Framework (1986) has been utilised, which seeks to sort knowledge into six different categories: three practical and three theoretical. The data collection consisted of observations made from lessons where the students solved math problems in

The thesis explores the agency of material artefacts in shaping co-presence and facilitating social interaction in three central squares in Malmö, Sweden: Stortorget, Lilla Torg, and Gustav Adolfs Torg. Drawing on a relational approach to space and Actor-Network Theory, the study combines structured and unstructured observations to analyse patterns of mobility, activity, and interaction. Findings

Många studenter som läser matematik på universitetsnivå, vare sig det är på ett ingenjörsprogram eller matematiklärarprogram, upplever svårigheter i sina studier. Siffror verkar peka på att hälften av ingenjörsstudenter hoppar av sina studier innan de tar examen. Detta är inte helt i enlighet med ett av gymnasieskolans mål, nämligen att gymnasiet ska vara högskoleförberedande. Det verkar då finnasStudents studying mathematics-intensive programmes have a very high rate of dropping out before graduating. This, in a Swedish context, is despite upper-secondary schools saying that students will be prepared to study at a university level upon graduating upper-secondary school. The aim of this study was to investigate whether the perceptions of mathematics as a subject differ between upper-second

Med ett rikt forskningsläge om fördelarna med att inkludera matematikhistoria i undervisning är det intressant att undersöka i vilken utsträckning som matematikens historia faktiskt genomsyrar matematikundervisningen. Med bakgrund i detta har examensarbetets syfte varit att undersöka inom vilka delar och på vilka sätt som matematikhistoria framställs i matematikläroböcker på gymnasiet. Frågeställn

This study aimed to examine and analyze how social workers perceive the new Social Service Act and its ambition to reduce individual needs evaluations. The new Social Service Act also includes increased access to receive social support without social workers’ decision-making. The study aims to generate an understanding of social workers' experiences regarding their professional practice relate

In a society facing rising sea levels and the associated challenges, such as flooding, there is a growing need for climate adaptation measures. This thesis aims to examine climate adaptation efforts in the region of Skåne, Sweden, by exploring the role of insurance companies – an important stakeholder in the housing market as insurance is a requirement for most bank loans – in urban planning. Addi

This thesis explores the application of Graph Neural Networks (GNNs) for relative depth estimation from dense matches between images. The main goals were to investigate the feasibility of using dense matches alone for this task, assess the performance improvement offered by GNNs over classical methods, and identify the most suitable features. The methodology involved utilizing the matches from Den

In today's urban and regional planning, climate change has become a challenging issue, as it has significant effects on sustainability. For Swedish cities, the global temperature has increased by an average of 1,5 degrees celsius since the period between 1961 and 1990. Due to this, climate adaptation is an important asset to limit the negative effects of more intense weather resulting from cli
