Efforts are made in radiographic examinations to obtain the best image quality with the lowest possible absorbed dose to the patient. In dental radiography, the absorbed dose to patients is very low, but exposures are relatively frequent. It has been suggested that frequent low-dose exposures can pose a risk for development of future cancer. It has previously been reported that there was no signif

The purpose of this study is twofold. Firstly, it aims to contribute to research by creating an understanding of how partners are selected in practice by an open innovation community. Secondly, it aims to contribute to research by building on the theories of causation and effectuation, as well as bricolage - a novel approach to partnership selection. We took an interpretive epistemological stance,
Background: SCOR is a worldwide accepted and renowned process reference model that is developed and endorsed by the non-profit organization Supply Chain Council. It’s a cross-industry diagnostic tool for supply chain management. Consafe Logistics wanted to know if a performance measurement system for warehouse activities could be developed based on the SCOR model, and how it could be applied in th
The MENA (Middle East and North Africa) region enjoys a high availability of clean renewable energy sources, especially solar. In recent years, several countries within the region have introduced policy instruments to encourage the deployment of distributed solar photovoltaic (PV). This thesis reviews and evaluates policy instruments adopted in Egypt, Palestine and Tunisia. The experiences from th
Purpose: The purpose of the thesis is to critically review different pricing strategies with a special focus on Revenue Management and discuss the possibilities and challenges for hotels when optimising their profitability. Methodology: We have conducted three case studies on hotels located in the Öresund region. The studies were done with a qualitative research approach. The respondents are all w
Cities are becoming smart to cope with the challenges associated with urban development. One of the cities trying to become smart is the City of Stockholm, which in 2017 adopted a strategy to become the world’s smartest and most connected city. However, becoming a smart city is not easy. The transformation requires a new organizational approach and innovation in management, which the City of Stock
The present study aimed to increase understanding of how singing activities may be initiated in primary school, and what support and assistance teachers require to conduct singing activities as an integrated part of the school day. Five music teachers participated in a focus group interview. The following main themes were identified: 1) pedagogical and methodological flexibility, 2) the role of ro
The reassignment technique is used to increase localization for signal components in the time-frequency representation. The technique gives perfect localization for linear chirp signals and constant frequency signals. Despite the recent interest in using the reassignment technique to determine phase-shifts, no general expression of cross-spectrogram reassignment vectors exists. This submission aim
Temperature, a key environmental stressor, can induce changes at the molecular levels in the body of living beings, which are necessary for adaptation and survival under altered conditions. We investigated the effects of acute cold (3 °C) and heat (32 °C) shocks on hemolymph protein profiles in marbled crayfish. Results showed that cold shock induced a metabolic shift toward glucose production by
Background: Blood cultures (BCs) are key diagnostic elements for sepsis patients. Accurate preanalytical procedures are substantial, and results should be available as soon as possible to guide adequate antimicrobial treatment. This study aimed to evaluate BC collection practices and diagnostic capacity across European hospitals. Methods: This cross-sectional survey investigated BC diagnostics in
The incidence of melanoma is rising and will require more efficient diagnostic procedures to meet a growing demand. Excisional biopsy and histopathology is still the standard, which often requires multiple surgical incisions with increasing margins due inaccurate visual assessment of where the melanoma borders to healthy tissue. This challenge stems, in part, from the inability to reliably delinea
Vitrified bonded aluminum oxide grinding wheels are widespread in use for many applications in grinding, such as internal plunge grinding. However, there are challenges when it comes to the measurement, analysis and (geometric) modeling of their topography, which is crucial to understand and model the influence of the topography on the process behavior. Methodological advances allow for the detail
BACKGROUND: This study aimed to evaluate the prevalence of pathogenic/likely pathogenic cardiomyopathy variant carriers in a multiancestry US population and examine the risk of adverse clinical outcomes. METHODS: This retrospective cohort study included multiancestry US adults aged ≥18 years with sequencing data from the All of Us Research Program. Pathogenic/likely pathogenic variants in cardiomy
PURPOSE: We performed an exploratory analysis of prostate cancer-related pain and fatigue on health-related quality of life in patients with metastatic castration-sensitive prostate cancer receiving apalutamide (240 mg/day) or placebo, with continuous androgen deprivation therapy (ADT), in the phase 3, randomized, double-blind, placebo controlled TITAN trial (NCT02489318). MATERIALS AND METHODS: P
2024 marks the second anniversary of the Russian full-scale invasion of Ukraine. The war has resulted in large numbers of Ukrainian refugees entering EU member states, including Germany. As far-right parties are on the rise across Europe, the topic of immigration is high on the political agenda again. Mainstream right and far right parties are competing for the discursive upper hand on the top
Plant-based ice cream and whipping cream are increasingly popular as sustainable alternatives to traditional dairy products. Their low fat content makes them much healthier than high-fat dairy products. However, achieving desirable texture and stability in plant-based desserts remains a challenge. This study investigated how different processing conditions (homogenization pressure, upstream/downst
The thesis examines how the American Recovery and Reinvestment Act (ARRA) was legitimised during the 111th U.S. Congress. Although ARRA was introduced as a response to the f inancial crisis with the aim of supporting those most affected, scholarship has shown that its benefits were distributed unevenly. Using critical discourse analysis the thesis analyses congressional hearings and house floor de
