Nickel gallium alloys have recently been discovered as a promising material for the catalyzation of methanol synthesis from carbon dioxide. Due to the novel nature of the material system for this purpose, there is a large potential for optimization in terms of catalytic activity and selectivity for methanol. Optimization through engineering of phases and facets in such materials is often difficult
This thesis compares portrayals of Syrian and Ukrainian refugees in Swedish main stream media in 2015 and 2022, through a mixed methods approach employing frame analysis and Critical Discourse Analysis. By examining how these two groups are represented, the study reveals quantitative and qualitative patterns of differential portrayals demonstrating a moral exclusion of Syrian refugees. Viewed thro
With the advent of 5G technology, there is a growing need for advanced antennas that can support multifunctional apertures efficiently and with minimal interference, especially at millimeter-wave (mmWave) frequencies. The thesis addresses this challenge by designing, simulating, and evaluating a cloaked dipole antenna designed for 5G applications. The main concept of this work is a cloaking mechan
This study looks at the expectations of young adults in Sweden regarding parental leave and work after having a child. It explores how men and women perceive their roles and responsibilities as parents. The main research question is: “What expectations do young adults have about parental leave and work hours after having children?” Sub-questions include their personal expectations and their views
The aim of this study was to examine the effects of episodic future thinking (EFT) on delayed gratification using a perceptual reward paradigm. A total of 43 participants, aged 18 to 56, were recruited and asked to imagine scenarios under two conditions (EFT and control). The influence of these scenarios on the ability to delay gratification were examined in an intertemporal choice task, where pho
In my thesis I have researched civil society organisations’ (CSOs) participation in climate change policies in Cambodia. CSO participation in climate change policies is an under-researched topic globally, but especially in Southeast Asia. Empirical data was gathered through interviews with CSO representatives in organizations who are engaged in climate change mitigation and adaptation (CCMA). I ha
In the last two decades, Japan has articulated a more proactive cybersecurity posture amid the increasing sophistication of cyberattacks and the relevance of technology for society. Those initiatives revolve especially around the response against China’s grey zone activities, which are not exclusive to cyberspace, and emerge as a result of issues in other domains. However, Japan has never directly
Disasters can generate up to fifteen times the annual rates of waste generated by the impacted communities and overwhelm the capacities of waste management systems. Disaster waste influences almost every aspect of response and recovery, is risky, and can be time-consuming and costly to clean-up. Disaster waste management (DWM) is, therefore, a key, and often neglected step for response and recover
Corporate sustainability (CS) has gained widespread recognition, coinciding with an increased focus on climate change. The media plays an important role in shaping public perceptions and policies regarding CS, the extent of non-financial information disclosure, and influencing how industries are viewed. However, the pharmaceutical manufacturing sector is significantly under-researched in relation
With the climate change the frequency of disasters are increasing all over the world. Hospital is an important organization which has significant role and responsibility during and after disaster. Proper preparation from beforehand is necessary to handle disaster related mass emergency. The objective of this scoping review is to offer a thorough overview of disaster preparedness among hospitals in
The composition of food includes water, fat, carbohydrates, protein, etc. which are eaten by humans to get nutritional value to live life. However, the pervasive consumption of adulterated food poses a serious threat to people of all ages. This situation is correlated to victims of around 2.5 million people annually. Food adulteration not only intertwines with human rights but also threatens our b
Physical activity is essential for health and well-being, as recognized by the World Health Organization (WHO), which defines it as any bodily movement produced by skeletal muscles that requires energy expenditure. Recommended levels of physical activity vary depending on age, with children needing at least 60 minutes per day and adults requiring 150–300 minutes of moderate-intensity activity per
Recently, a newly developed family of decoders named as Guessing Random Additive Noise Decoder (GRAND) has been gaining attention. The key idea of the decoder is to look for the most probable error vectors that interacted with the transmitted message, producing the received block. Among the different variations of the algorithm, the soft-input soft-output (SISO) decoder, known as SO-GRAND, emerges
Unravelling the home is an anecdotal mapping of the house and the objects within it to seek a deeper understanding of what a home is constructed of. Through prints, photographs, observations, interviews and drawings, the house is slowly unravelled to visualise the material and the immaterial components, including the norms and narratives, that makes it a home. The notion of the home as a physical
This thesis focuses on the development of an image stabilization system for body-worn cameras. Body-worn cameras are frequently used in dynamic situations, exposing them to intense movements. Capturing sharp, high-quality footage in these conditions requires effective image stabilization systems. This investigation involved mapping the nature of the disturbances experienced by the body-worn camera
The global food system is a cause of the worldwide poly-crisis in climate change and ecological decay. Ecological food systems have been emerging to contest the ruinous food production model. This thesis explores one branch of ecological food production: urban farming. Focused on the Swedish context, cases in Växjö, Malmö, and Göteborg were analyzed to examine how urban farms and involved agents n
