New 2D materials with high electron mobility can potentially be used for small and energy efficient electronic devices in the future. One such material that has been studied intensely is graphene. Despite the large amount of studies, the question of how to create useful shapes of graphene remains unanswered. In this work I studied how graphene may be spatially etched by intercalating oxygen before
Vilka faktorer dominerar när en människas identitet fastställs? Uppfattas internationellt adopterade kineser som “mindre” kineser i sitt födelseland än de kineser som fötts, vuxit upp och förblivit bosatta i födelselandet? Denna studie undersöker synen på nationell och kulturell tillhörighet genom att ställa flera sammanlänkade frågor om ras, etnicitet, nationell och kulturell tillhörighet. Interv
This experimental study investigates the effect of diversity initiatives on White individuals' perception of discrimination against minorities and whether this relationship interacts with their meritocratic values. With an increased global emphasis on diversity and inclusion, organizations strive to reduce discrimination and instead promote a culture that values diversity. However, the effecti
A Warehouse Management System (WMS) is a software that tracks and manages warehouse activities. The first WMS was introduced in 1975 and today the WMS market is valued at over USD 3 billion. Most warehouses use one as quality assurance becomes unlikely plausible without software support. This thesis focuses on Company X, who are the third-largest manufacturer by revenue in their industry and a
Heavy metal pollution is a worldwide crisis that threatens thousands of species and ecosystems. Within the next couple of decades, the majority of the global population is predicted to live in urban areas which will likely cause the pollution crisis to become even worse if preventive actions aren’t executed now. Hence, proper implementation of urban green spaces and infrastructure is imperative to
The reliable operation of nuclear reactors is contingent upon precise control mechanisms for critical components, such as the head circulation pumps. This master thesis investigates an innovative approach to address the ramp-down speed of these pumps during external electrical grid failures by exploring the application of a supercapacitor group. Presently, the existing solution relies on a fly-whe
Flowering plants depend on pollinators for reproduction, and this entails selection on plant traits linked to phenology, attractiveness and pollination efficiency. Current environmental changes are however acting upon both parties, which in turn affects the interactions between them. In order to better understand how these changes manifest, this study looked at five plant species in semi-natural g
Under det svenska miljonprogrammet byggdes drygt en miljon bostäder under en 10-årsperiod, där lamellhus i 3-våningar är den dominerande hustypen. Produktionen var industriell och rationell med enhetliga metoder och utföranden. Byggnaderna har under åren haft varierad grad av underhåll, men genomgående för husen har generellt varit bristfällig skötsel. Gemensamt för en stor del av byggnaderna är sA fifth of Sweden's current housings were built during the Million Programme (1965 - 1974). A substantional amount of these houses are in a great need of renovation, and furthermore, these houses do not have the same energy performance that modern houses have. As a part of decreasing the building sector's carbon emissions, reaching the climate targets and at the same time utilize already e
Sveriges föreningskultur bidrar till att miljontals individer årligen får ta del av idrottens positiva effekter, såsom förhöjd fysisk och mental hälsa. Även samhället gynnas av en aktiv befolkning gällande exempelvis integration. Utan ideellt engagemang hade inte detta varit möjligt och det är därför av stor vikt att föreningsaktiva har tillgång till digitala verktyg som underlättar deras vardag o
Uppsatsen bygger på en empirisk tematisk innehållsanalys med syfte att undersöka hur svenska partier använder sig av negativ kampanj under valåret 2022 på Instagram. De partier som mäts är Socialdemokraterna, Sverigedemokraterna och Moderaterna. Tematisk analys har använts induktivt vilket innebär att materialet formar teman som hittas i primärmaterialet. Negativ kampanj används som teori och en s
During the production of Tetra Pak’s packaging material, holes are cut for straws and caps, generating paperboard scraps known as confetti. These scraps must be removed from the machinery to prevent build-up and potential blockages. To design efficient extraction systems, experiments and simulations are employed to understand the phenomena of confetti transport. Confetti are introduced into a simp
Submarines constitute an important part of modern navies around the world. As they are systems with a high level of complexity, the production phase of a submarine is long and prone to flaws. The earlier these flaws are detected, the less of an impact they have monetarily and on the production timeline. SAAB Kockums build submarines in sections, in which platforms are mounted with equipment o
Malaria is an infectious disease that causes death and illness in the world. The effectiveness of antimalarial drugs like chloroquine has decreased, leading to an increase in the use of organometallic complexes to treat malaria. Ferroquine is an organometallic compound that is a newly developed antimalaria drug that contains a 4-aminoquinoline unit that is coordinated to ferrocene. Eight new metal
GNSS is currently the most prominent method for outdoor positioning, providing an accuracy of approximately 5 metres in good conditions. However, for environments such as dense city areas or indoors, a GNSS signal reception might not be possible. An alternative method of positioning is the fingerprint-based method, which has been widely adopted for indoor positioning by sampling the signal strengt

There is a need to closer characterise the molecular changes associated with progression from low to high mortality stage cutaneous T cell lymphoma. This has been challenging since there is high inter-patient heterogeneity in the genetics and transcriptomics of the malignant T cell populations. Modern technology has enabled single-cell resolution as well as spatially guided cell selection for whol
Hybrid zones represent crucial areas where two populations meet, mate, and produce hybrid offspring, serving as natural laboratories for studying genetic mechanisms underlying ecological traits and reproductive isolation. In Sweden, the common chiffchaff (Phylloscopus collybita) is represented by two subspecies: P. c. abietinus, which colonised northern Sweden through Finland at least 200 years ag
