Due to higher demands on the electrical systems in the aviation industry, the generation and distribution of electrical power, in aircrafts, needs to be researched and developed further. Key requirements include increased power capacity to meet future demands, a transition from AC to DC supply and an increased voltage level. For power generation, a generator is coupled to the jet turbine which mus
Degradable starch microspheres (DSMs) are promising biomaterials with expanding medical applications due to their biocompatibility and controlled degradation. DSMs are produced by forming a water-in-oil emulsion using a starch solution, an emulsifier e.g. Starch Acetate Butyrate (SAB) and toluene, followed by crosslinking using a crosslinker, e.g. epichlorohydrin (ECH). The relationship between re
In today’s increasingly digital world, cybersecurity challenges extend far beyond the organizational perimeter, affecting both professional and personal domains. While organizations invest in comprehensive cybersecurity policies to mitigate risks, less is known about how these policies influence employees’ personal cybersecurity outside the workplace. This study investigates that relationship thro
Bygg- och fastighetssektorn står för över 20 procent av Sveriges växthusgasutsläpp, vilket gör den till en central aktör i omställningen till ett hållbart samhälle. För att uppnå klimatmål och underlätta cirkulärt byggande krävs effektiva och spårbara miljödataflöden genom hela byggprocessen. Projekteringsfasen erbjuder särskilt goda möjligheter att påverka dessa flöden, tack vare digitaliseringen
This thesis explores a classically conformal extension of the Standard Model featuring a real scalar singlet field as a Dark Matter candidate. In this framework, electroweak symmetry breaking arises radiatively via the Coleman-Weinberg mechanism, foregoing explicit mass scales and preserving classical scale invariance at tree level. The singlet scalar, stabilized by an imposed Z2 symmetry, is inve
Amid a global housing crisis that leaves more than 1.6 billion people inadequately housed, dominant legal and policy frameworks still define “adequate housing” largely in terms of fixed outcomes such as tenure security, affordability, and habitability. This thesis argues that these lists overlook a critical dimension: people’s housing agency, the real freedom to shape their housing situation. Grou
Music’s diverse psychological roles include possible cognitive enhancement, however, results are either insufficient or mixed based on already existing literature. The current interventional study observed the influence of musical stimuli on time perception and sustained attention possibly explained by altered states of consciousness. 30 participants were assigned equally to two different musical
This thesis explores how Employee-Driven Innovation (EDI) unfolds within Swedish municipal organizations and identifies how EDI is managed and structured, and what kind of innovations that are created in such organizational environments. While innovation is increasingly emphasized in the public sector, this study reveals that its practice is far from uniform. Through qualitative studies of three m
Forskningsfrågor Hur beskriver de anställda företagets identitet? (och) Hur upplever de anställda att verksamheten styrs? Syfte Syftet är att bidra till förståelsen av identitet som styrning. Mer precist, hur identitetsreglering sker dynamiskt med inflytande av både medarbetare och chefer. Metod Studien baseras på sju semistrukturerade, kvalitativa intervjuer med anställda från ett litet nordiskResearch question How do the employees describe the company’s identity? (and) How do they perceive the way it is controlled? Purpose of study The purpose is to contribute to the understanding of identity as a form of control. More specifically, how identity regulation occurs dynamically through the influence of both employees and managers. Methodology The study is based on seven semi-structured,
This thesis explores the positioning of internal crisis communication in relation to external communication, specifically within the context of governmental crisis response. Guided by the case of the Lebanon crisis in 2024, this study investigates how crisis experts from a European Ministry of Foreign Affairs interpret internal communication across the three phases of crises, drawing on the Rhetor
This study examines how the use of leverage conditions both market-based and operational outcomes in U.S. equity Real Estate Investment Trusts (REITs), with particular focus on the period surrounding the 2022-2023 monetary tightening cycle. Despite REITs' prominence as capital-intensive, payout-constrained institutions, little empirical research has explored how their capital structure choices
Public organisations need legitimacy to operate and there are many ways for them to gain, maintain and repair it. Without legitimacy, public organisations can face challenges such as legitimacy gaps or crises, which can have lasting effects on their function and authority. This thesis aims to shed light on how public organisations in Iceland communicate when their legitimacy is questioned and wha
Non-native plants are a growing problem in Antarctica. By encroaching on native plants’ habitats, they risk leaving the last frontier of authentic wilderness irreversibly altered. As the climate continues to change and more people visit Antarctica, non-native plants’ spread and impacts are expected to become more severe. The Protocol on Environmental Protection to the Antarctic Treaty prohibits in
NMDA receptors are ligand-gated ion channels assembled as heterotetramers composed of glycine-binding GluN1 and GluN3 subunits (GluN3A-B), and glutamate-binding GluN2 subunits (GluN2A-D). Their involvement in various psychiatric and neurological disorders makes them potential therapeutic targets. However, compared to the extensively studied GluN1/2 NMDARs, the functional, physiological, and pharma
Global biodiversity is heavily damaged by human interventions. There are multiple drivers for human-caused biodiversity loss; however, land use linked to agricultural production is the leading one. In response to this major threat, the interest in and importance of assessing the potential biodiversity impacts, particularly those related to land use, have grown significantly. Especially within fram
This thesis investigates how income influences the way parents in Sweden share paid parental leave. Although the Swedish parental leave system is universal in design, its use varies across income groups and regions. By analyzing national data grouped by income level and regional data from all 21 counties between 2005 and 2019, the study examines how financial position and local context relate to t
HPLC is one of the most widely used analytical techniques in the pharmaceutical industry used for separation and identification of compounds in complex formulations. Despite its advantages, HPLC method development remains challenging. This is due to the need to optimize multiple interdependent parameters simultaneously, while gaining high precision, reproducibility, and efficiency. Even minor cha
