Att fånga upp koldioxid från industriella utsläpp eller direkt från atmosfären och omvandla det till mer värdefulla föreningar, kallat "carbon capture and utilization", är en intressant metod för motverkandet av den globala uppvärmningen. Med en katalysator kan koldioxid och vätgas användas för att tillverka metanol som är användbart som bränsle och i kemikalieindustin. En nyligen upptäcNickel 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

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

Making live, single-celled organisms fluoresce Protist is a term for a type of organism that has a nucleus and is not an animal, plant or fungus. Most protists are single-celled and can be found in all types of environments across the planet. Protists are highly diverse and understudied, and researching protists directly from the environment has many challenges. One method for researching microbe

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

Är åldersspecifika olikheter på proteinnivå nyckeln till nya behandlingar? Behovet av nya behandlingsmetoder för leukemi är ett faktum. I denna studien har vi undersökt leukemiceller från barn och vuxna på proteinnivå. Genom att identifiera åldersrelaterade olikheter kan dessa utnyttjas i framtida utveckling av behandlingar riktade mot särskilda varianter av leukemi för barn och vuxna. Leukemi

Avloppsreningsmetod för att rena dricksvatten Målet med dricksvattenrening är att bli av med oönskade ämnen i vattnet, så som sjukdomsframkallande bakterier och organiskt material. Detta säkerställer inte bara vattnets säkerhet utan också dess smak, lukt och utseende. Det finns flera olika metoder för att rena vatten, och vilken metod som används beror på vattnets kvalitet och ursprung, samt vilkAt the drinking water treatment plant (DWTP) at Ringsjöverket (Sweden, Stehag), where this project is executed, a process of rapid sand filter (RSF) and slow sand filter (SSF) is used as a part in treating surface water into drinking water. The Moving bed biofilm reactor (MBBR) is a simple and strong biological process that has been shown to be effective in treating polluted raw water from nitroge
