This master's thesis explores the phenomenon of intelligence disclosure within the context of digital public diplomacy. The focus is on the "Taurus Scandal," where a confidential conversation among high-ranking German military officials about potential Taurus missile deliveries to support Ukraine was intercepted and published by Russia, leading to political and diplomatic turmoil wit

In recent years, Swedish communication agencies have increasingly emphasized the value of insight-driven communication for strategic processes. Advocates argue that this methodology enhances creative potential, more accurate target audiences, and improves various organizational functions. Despite some attention in strategic communication research on topics such as data-driven approaches and the st

In today's rapidly evolving digital age, organizations are continually challenged to seam- lessly integrate digital systems into their operations and works. This thesis examines the criti- cal role of internal leadership communication in facilitating user adoption of digital systems within large international organizations, using IKEA as a case study. Grounded in transforma- tional leadership

The complexity that organizations face in the modern external environment calls for employees to generate novel ideas for solving problems. Despite acknowledging the importance of creativity for innovation, creativity assumes a subsidiary role in contrast to productivity in the workplace. The purpose of the study is to expand knowledge in the field of Strategic communication on factors that foster

The ongoing war in Ukraine is associated with unprecedented radiological threats to the public in Ukraine and the neighboring countries. This calls for fundamental revision of the preparedness plans and established approaches to radiological monitoring of the populations affected by potential radiological emergencies. Dosimetric information will be needed for triage of victims and support to decis

This thesis explores the contemporary cultural and political influences that both compete for and contribute to the shaping of England’s national identity. Amidst recent politicisation of nationhood and belonging, counter-narratives to prevailing regressive discourses have emerged and this thesis aims to elevate the progressive discourses that better represent modern-day, multicultural England. Th

The partnership and development cooperation between the European Union (EU) and Africa is described as a key priority for the European Commission and their aim is to further strengthen the partnership (European Commission 2020). However, the relationship between the European Union and the African continent has a deep and complex history that has been characterized by colonial ties and unequal powe

Skyddade av vad de kriminella trodde var ett säkert krypterat kommunikationsverktyg smeds planer för kriminella handlingar helt filterlöst. Det som brottslingarna inte visste var att krypteringsverktyget övervakades i realtid, genom ett framgångsrikt internationellt polissamarbete. I denna uppsats undersöks hur Operation Trojan Shield, OTS, framgångsrikt infiltrerat den krypterade kommunikationspl

Expanders are key equipment in energy storage systems. Traditional sliding vane expanders have many problems, such as severe friction, non-uniform flow fields and limited flow rates. To address these issues, a novel rotating-cylinder sliding vane rotary expander (RC-SVRE) with small eccentricity and guide vane ports is proposed where the rotating-cylinder keeps a distance from the rotor to reduce

Recent self-reported and cross-sectional survey evidence documents high levels of mental health problems among PhD students. We study the impact of PhD studies on mental health care uptake using Swedish administrative records of prescriptions for psychiatric medication for the full population of PhD students. First, we provide descriptive evidence that PhD students collect psychiatric medication a

To resolve the various types of biological ice nuclei (IN) with atmospheric models, an extension of the empirical parameterization (EP) is proposed to predict the active IN from multiple groups of primary biological aerosol particles (PBAPs). Our approach is to utilize coincident observations of PBAP sizes, concentrations, biological composition, and ice nucleating ability. The parameterization or

Both straight and curved carbon fibers are widely used in various commercial gas diffusion layer (GDL) fabrications. The effect of the different carbon fiber curvatures on two-phase flow dynamics within the cathode GDLs of proton exchange membrane fuel cells remains unclear. In this study, we investigate liquid transport in three types of GDLs with varying fiber curvatures using the two-phase volu

Arbetet handlar om en studie gällande hur konsumenters inställning och attityd till hållbar konsumtion av kläder skiljer sig från deras faktiska köpbeteende. Inledningsvis kommer bakgrunden att beskriva klädbranschen och dess påverkan på samhälle och miljö, detta kommer sedan att trattas ner till att se hur konsumenter tar ställning och agerar inom detta ämnet. Ämnet problematiseras vidare med bes

Inom stålindustrin är naturlig konvektion en konventionell kylningsmetod. Genom att öka kylhastigheten jämfört med naturlig konvektion kan produktiviteten öka då kylbäddarna kan kortas och stålplåtarna tillbringar mindre tid under kylning. Detta frigör plats och sparar tid. Då möjligheten att använda infraljud till kylning redan har bekräftats genom experiment, ska denna masteruppsats försöka besvIn the steel industry, a conventional cooling method is natural convection. By increasing the cooling rate compared to natural convection, the productivity can be increased as cooling beds can be shortened, and the steel plates spend less time in cooling. This frees up space and saves time. As the ability to use infrasound for cooling had already been verified through experiments, this master thes

The degradation of trout and bovine hemoglobin (Hb) and their pro-oxidant activities in washed cod muscle mince (WCM) were studied using simple pH-shifts to simulate gastrointestinal (GI) conditions (pH 7 → 6 → 3 → 7), as well as full static in vitro GI digestion. Following gastric acidification to pH 6, metHb formation increased, especially for trout Hb. Subsequent acidification to pH 3 promoted

In vitro digestion studies often use animal digestive enzyme extracts as substitutes of human gastric and pancreatic secretions. Pancreatin from porcine origin is thus commonly used to provide relevant pancreatic enzymes such as proteases, amylase and lipase. Rabbit gastric extracts (RGE) have been recently introduced to provide gastric lipase in addition to pepsin. Before preparing simulated gast

A new technique to speed up the phase separation of aqueous two-phase systems is described. The technique is based on the addition of magnetically susceptible additives (ferrofluids or iron oxide particles). In a magnetic field such additives will induce a faster phase separation. In one approach, dextran-stabilized ferrofluid was added to an aqueous two-phase system containing polyethylene glycol

Collagen VI (Col-VI) is an extracellular matrix protein primarily known for its bridging role in connective tissues that has been suggested to play a neuroprotective role. In the present study we report increased mRNA and protein expression of Col-VI in the hippocampus and cortex at a late stage of epileptogenesis in a post-status epilepticus (SE) model of epilepsy and in brain tissue from patient

Microbial, algal, plant and animal cells have been immobilized, with preserved viability, by entrapment in various matrices according to a new bead polymerization technique. The cell polymer/monomer mixture is kept suspended in a hydrophobic phase such as soy, paraffin, or silicon oil, tri-n-butylphosphate, or dibutyphtalate, which is compatible with the cells. The various monomers or polymers tes

We propose a novel non-negative spherical relaxation for optimization problems over binary matrices with injectivity constraints, which in particular has applications in multi-matching and clustering. We relax respective binary matrix constraints to the (high-dimensional) non-negative sphere. To optimize our relaxed problem, we use a conditional power iteration method to iteratively improve the ob
