Inflammation and subsequent endothelial dysfunction are main players in the vascular component of hypertension, and recent findings points to a key role of Sphingosine- 1-Phosphate and its signaling pathways in its pathophysiology. In neurodegenerative disorders such as Alzheimer’s disease, hypertension is the main modifiable risk factor, but insights regarding S1P receptor modulation in response
This Master Thesis aims to show an approach to the design of parallel robots,specifically the development of its kinematics. To do this, screw theory will be used, focusing on its theoretical bases and taking it later to practice. First, a theoretical definition of the inverse and forward kinematics of a parallel robot is carried out. Subsequently, algorithms are generated in Python that verify t
Aspects of Error Quantification and Evaluation in Digital Elevation Models for Glacier Surfaces This study explores methods to quantify and evaluate error in digital elevation models (DEMs) built from remotely sensed elevation data of the Hintereisferner glacier. A special focus lies on glacier surfaces because glaciers are often inaccessible for field observations but at the same time prone to m
In this thesis, a new probabilistic risk assessment tool for road tunnels has been verified and validated. The verification and validation were performed along with a literature review to find different key variables that affect the risk in a road tunnel and find out how these variables can be handled. Examples of variables are heat release, ventilation mode and factors within evacuation modelling
Using laser it is possible to measure the backscattered light from insects. The resulting signal can then be analysed in order to potentially determine the species of the insect. Estimating the fundamental wing beat frequency (FWBF) of insects is important in order do this classification of species, which is an area of research that has been explored previously. In this thesis, the relative phase
Remaining competitive as a company in a rapidly changing global environment is becoming challenging from day to day. In recent years, the establishment of so-called shared service centers gained popularity and growing number of companies centralizes supporting service in separate business units to bundle those services and perform them efficiently for the rest of the company. The mystery, however,
Due to increasing awareness and consumer demands it has become important for companies to develop an economical and environmentally sustainable alternative to traditional petroleum-based plastics. The transition from fossil material to bio based is important for the future of people and planet, still, how the transformation should be implemented is yet unknown. In this report, the possibilities of
Conventional agriculture in Sweden is facing challenges with low resilience to a changing climate and decreased biodiversity. Silvoarable agroforestry is an alternative land use practice that contain a woody perennial and crop in the same field. Trees on cultivated land break up large monocultures, increase biodiversity, creates functional diversity, and produces more commodities. This land use pr
This degree project focused on the evaluation of the facilities, production process and conditions within a brewery production site in order to identify potential contamination risks in the beer production process and suggested actions for improving and enhancing protection against contamination. The project was performed in collaboration with a microbrewing company that produces beers with differ
As part of a research grant aimed at producing chicken feed from the novel microalgae Scenedesmus sp., called the ReMAPP project, this thesis investigates opportunities to increase the conservation potential and protein digestibility utilizing solid-state lactic acid fermentation and commercial enzyme additives. The lactic acid fermentation mimics the traditional agricultural ensiling process, whe
In recent years, microwave applications in the food products have attracted increasing attention by the food packaging industry and the consumers due to their convenience, low energy and water usage and short processing time giving them a sustainable advantage over competing technologies. In-pack pasteurization represents one of the fastest developing technologies in preparing and delivering safe
This thesis investigates the remanufacturing potential of the electric front cross differential (eFXD) within the context of the circular economy (CE) and the R‑framework. Environmental assessment, mechanical validation and structured component classification are combined to identify opportunities and limitations for remanufacturing. The results show that a limited number of components, the tube h
Most pre-clinical models fail to reliably predict the effects of immunotherapeutic drugs intended for treatment of cancer. A major limitation is their inability to reliably model the tumor microenvironment (TME), a complex and essential component of tumor resistance to treatment. Patient-derived tumor models, like precision-cut tumor slices (PCTS), preserve the tumor architecture and capture the c
The aim of this study was to investigate whether cross-site networking of environmental managers in globally active companies can offer a solution for the efficient internal use of intangible resources. In addition, it examines whether findings from research and practice on interorganisational environmental networks can be transferred to intraorganisational contexts. The study is based on a case s
This thesis investigates everyday misrecognition of Roma flower-sellers in Istanbul’s Ataşehir district, focusing on how they navigate ethnically mixed neighborhoods and workplaces. Drawing on Honneth’s recognition theory, Giles’s critique, and Gramsci’s cultural hegemony, it examines how racialization and normative discrimination shape daily interactions. Based on one month of ethnographic fieldw
Hybrid detectors, consisting of semiconductor sensors bonded to a readout Application-Specific Integrated Circuits (ASICs), are widely used for single-photon detection in photon science and high-energy physics. The Timepix3 readout chip provides precise Time-over-Threshold (ToT) and Time-of-Arrival (ToA) measurements, making it a valuable tool for sensor characterization. This thesis presents the
This study looked at a fluorocarbon-free water-repellent treatment on different types of polyester textiles in order to test the durability of the treatment in simulated wear-and-tear tests in collaboration with Thule Group. This research was being done in order to gain a deeper understanding in the strengths and limitations of the C0 Water-Repellent (C0WR) treatment on polyester textiles. The stu
This master’s thesis examines similarities and differences in operational work, training, and the use of technology related to Smart Firefighting in Sweden and Hong Kong. Smart Firefighting has been proposed as a response to challenges arising from modern urban development, where data from smart buildings, combined with AI and digital tools, could support fire and rescue services. However, such da
This thesis focuses on how online activists react to online censorship imposed onto them by social media platforms and how the reactions shape the activists’ responses to the censorship. It does so by deploying a qualitative interview study design onto how Swedish individuals who advocate for Palestine online experience and respond to digital censorship on Meta’s social media platforms. In the st
