The metalorganic chemical vapor deposition (MOCVD) dynamics of beta-gallium oxide (β-Ga2O3) growth using trimethylgallium (TMGa) and oxygen as precursors were investigated through both theoretical thermodynamic analysis and experimental validation in a horizontal low-pressure hot-wall reactor. Thermodynamic analysis revealed that high-purity β-Ga2O3 can be grown through the complete combustion of

Heterogeneous integration of III-V narrow bandgap transistors on silicon technology is desirable for high frequency circuit implementations. Such high-speed transistors must, however, scale to large gate widths to be suitable for general circuit design. Averaging among many variable channels is a key challenge for nanowire devices. A simplified, but high-speed compatible, nanowire device process w

We report a Mueller matrix ellipsometer design using dual continuously rotating anisotropic meta wave plates, which determines the full set of Mueller matrix elements in the terahertz spectral range. The instrument operates in the frequency domain and employs a frequency tunable, solid state synthesizer based, continuous wave terahertz source with sub-MHz bandwidth. The implemented source permits

The main purpose of this study was to examine the relationship between adult attachment, denoted as mental representations of childhood experiences, and social relations. A secondary purpose was to examine the impact of prematurity on attachment and social relations in adult age. The study is part of a larger longitudinal study carried out by professor Karin Stjernqvist and Anne-Li Hallin, candida

Swedish Development Cooperation emphasizes the need for collaboration among actors on a national level. In that context, the purpose of the thesis is to investigate how Public Private Partnership (PPP) on Corporate Social Responsibility (CSR) may influence the changing role of the state. The thesis is informed by Critical Discourse Analysis. In order to investigate the social constructions of real

The provision of military and armed security services typically is the monopoly domain of the state. With the end of the Cold War legitimate private firms, however, expanded as worldwide providers of military and security services. The proliferation of private military companies echoes back to pre-modern eras when it was customary for state rulers to allocate force and security through the market.

The formation of ESDP (European Security and Defense Policy) is one of the most important building blocks shaping the European security structure and the European integration process since the beginning of the 21st century. Even though the integration engine was injured by the rejection of the European Constitutional Treaty in France and the Netherlands, the ESDP can be seen as currently one of th

Segregation är ett föränderligt tillstånd som är komplext och påverkar såväl enskilda individer som samhället i stort. Exempelvis är stadsplaneringen en bakomliggande orsak som kan påverkar segregationen i en stad. För att det verkligen ska kunna ske en förbättring är det emellertid av stor vikt att åtgärder vidtas på olika plan och av olika aktörer. Det ursprungliga syftet bakom arbete är att utSegregation is a changing condition that is complex and affects individuals but also the society. Urban planning is for example an underlying cause that can affect segregation in a city. However, in order for an improvement, it is of great importance that measures are taken at different levels and by different actors. The primary purpose of the report was to study the impact that urban planning h

Exploring a prolonged life cycle of materials through an adaptive transformation Take, make and waste. Our society is trapped in a linear economic system where we extract raw materials, process them into products and as they have served their purpose they are reduced to waste. This unsustainable mentality seeps through to all things consumable, from fashion and cellphones to kitchen counters and

Elevators has for a long period of time been regarded as unsafe to use as a means of egress. This is an opinion that has shifted in the last couple of years as technical solutions has been found to the initial problems when using elevators as an escape route. This report investigates the possibility to replace a staircase with emergency elevators as a means of egress in a buildning. The report als

Svensson (1997) föreslår att centralbanker på grund av implementerings- och utvärderingssvårigheter hos inflationsmål även bör ha ett mål för inflationsprognoser. Han argumenterar för detta med hjälp av en teoretisk modell som antar att den korta räntan, som centralbanken kontrollerar, påverkar BNP-gapet med en periods fördröjning, vilket sedan påverkar inflationen efter ännu en period. För att ma

Climate-focused study abroad relying on high-emitting travel poses a dilemma between study abroad and emission reductions. This study employs the three spheres of transformation investigating this dilemma through coding syllabi (n=156,) surveying educators (n=9,) and interviewing (n=14) Climate Action Network for International Educators (CANIE) affiliates considering whether studying climate chang

Purpose: The purpose is to describe the Malmö Breast Tomosynthesis Screening Project from the beginning to where we are now, and thoughts for the future. Approach: In two acts, we describe the efforts made by our research group to improve breast cancer screening by introducing digital breast tomosynthesis (DBT), all the way from initial studies to a large prospective population-based screening tri

Operando resonant photoelectron spectroscopy (RPES) combined with modulated chemical excitation revealed the dynamic evolution of Ce3+/Ce4+ redox states at the surface of CeO2 during the CO oxidation reaction. Using alternating CO and O2 pulses as chemically modulated signals, we monitored the surface states in the valence band region, unveiling the evolution of electronic structure during the cat

Using several melanoma proteomics data sets we created a single analysis platform that enables the discovery, knowledge build, and validation of diagnostic, predictive, and prognostic biomarkers at the protein level. Quantitative mass-spectrometry-based proteomic data was obtained from five independent cohorts, including 489 tissue samples from 394 patients with accompanying clinical metadata. We

I takt med att Sverige strävar efter att uppnå klimatneutralitet har återvinning av schaktmassor fått ökad betydelse. Vikten av samordning mellan olika bygg- och anläggningsprojekt har lyfts för att öka den cirkulära masshanteringen. Lokalt belägna återvinningsanläggningar för massor har angetts som ett sätt att underlätta återvinningen av massor. Samtidigt upplevs lagstiftningen som reglerar olikThe management of excavated materials is becoming more important as Sweden works towards climate neutrality. Improved coordination between construction projects and the use of local recycling facilities are seen as key to enabling circular mass management. However, the legislation governing the establishment and operation of mass recycling facilities is perceived as unclear, particularly regarding

The decline in areal BMD (aBMD) in men may start as early as age 19, but it is debated whether proximal femoral strength follows the same pattern. We measured FN aBMD in a cross-sectional cohort of 1101 men aged 18-28 yr with two-dimensional DXA. Body height, weight, jump height, grip strength, and maximum knee extension torque muscle strength were measured with standard tests, after which BMI was

Purpose: To achieve the high sensitivity of digital breast tomosynthesis (DBT), a time-consuming reading is necessary. However, synthetic mammography (SM) images, equivalent to digital mammography (DM), can be generated from DBT images. SM is faster to read and might be sufficient in many cases. We investigate using artificial intelligence (AI) to stratify examinations into reading of either SM or

OBJECTIVES: To describe the prevalence of cardiovascular disease (CVD) at the time of diagnosis of adult-onset type 1 (T1D) and type 2 (T2D) diabetes, in a recent cohort and compare to a previous cohort from the same region. Further, to explore factors influencing the prevalence of pre-existing CVD, including age, sex, body mass index (BMI) and C-peptide; in the later cohort also heart failure, hy

Cortical interneuron deficiencies, particularly involving the somatostatin (SST) subtypes, contribute to neurological and neuropsychiatric disorders. These interneurons are difficult to derive in vitro from human embryonic stem cells (hESCs) due to their late embryonic development and dependence on glial interaction. To this end, we developed a three-dimensional co-culture model of hESC-derived ne
