The paper describes a debris-free, efficient laser-produced plasma source emitting EUV radiation. The source is based on a double-stream Xe/He gas-puff. Its properties and spectroscopic signatures are characterized and discussed. The spatio-spectral features of the EUV emission are investigated. We show a large body of results related to the intensity and brightness of the EUV emission, its spatia
In experimental design and 3D reconstruction it is desirable to minimize the number of observations required to reach a prescribed estimation accuracy. Many approaches in the literature attempt to find the next best view from which to measure, and iterate this procedure. This paper discusses a continuous optimization method for finding a whole set of future imaging locations which minimize the rec
A previous study by the authors using a heated thermal manikin showed that the cooling rates of phase change material (PCM) are dependent on temperature gradient, mass, and covering area. The objective of this study was to investigate if the cooling effects of the temperature gradient observed on a thermal manikin could be validated on human subjects in extreme heat. The subjects wore cooling vest
Genome-wide association studies (GWAS) have identified more than 100 genetic variants contributing to BMI, a measure of body size, or waist-to-hip ratio (adjusted for BMI, WHRadjBMI), a measure of body shape. Body size and shape change as people grow older and these changes differ substantially between men and women. To systematically screen for age- and/or sex-specific effects of genetic variants
More scheduled outdoor stay is increasingly advocated for school children. This study measured 2(nd) , 5(th) and 8(th) graders' erythemal UV-exposure in September, March and May at four Swedish schools. We related those exposures, as fractions of total available ambient radiation, to the schools outdoor environments differing in amount of shade, vegetation, and peripheral city-scape quantified as
In this paper, we describe a novel approach to create 3D miniatures of persons using a Kinect sensor and a 3D color printer. To achieve this, we acquire color and depth images while the person is rotating on a swivel chair. We represent the model with a signed distance function which is updated and visualized as the images are captured for immediate feedback. Our approach automatically fills small
We introduce a multi-region model for simultaneous segmentation of medical images. In contrast to many other models, geometric constraints such as inclusion and exclusion between the regions are enforced, which makes it possible to correctly segment different regions even if the intensity distributions are identical. We efficiently optimize the model using a combination of graph cuts and Lagrangia
A concern that arises with any change in technique is whether it affects the long-term implant stability. The objective of this study was to evaluate the early migration, measured by radiostereometric analysis (RSA), and the functional outcome of the Triathlon™ cemented knee prosthesis, operated on with or without a tourniquet. During the last decades RSA has emerged as a way to assess prosthetic
AIMS/HYPOTHESIS: The increased all-cause mortality in patients with chronic diabetic foot ulcers cannot fully be explained by traditional cardiovascular risk factors. The significance of heart-rate-corrected QT (QTc) prolongation, a finding often seen in these patients, is unknown. Recently, the importance of metabolic control and hypoglycaemia has been discussed. The aim of this study was to eval
The aim of the present study was to validate a Swedish translation of the Gastrointestinal Quality of Life Index (GIQLI) questionnaire in patients with gallstone disease. Sensitivity to change, internal consistency, and test-retest stability were tested in 187 consecutive patients who underwent planned cholecystectomy. Construct validity was assessed by comparing the GIQLI score with the bodily pa
Inhalation as a method for drug delivery has been employed for more than 2000 years and serves many advantages for diseases in the respiratory tract, like cystic fibrosis and asthma. When administrating the drug directly to the respiratory tract it results in rapid effects and elimination of systemic side effects due to more targeted delivery. Dry powder inhalers (DPI) typically consist of the act
A lot of time and care have been put into exploring and explaining the power relations between nurses and nursing assistants, the emotional investment appropriate in care work, different views on leisure time for staff in this context (Warming, 2019; Habel, 2021; Jervis, 2002; Crocker, 2019). Less work has been done in exploring the complex relationships care workers have with their patients and h
The purpose of this thesis is to contribute to the current field of research on crisis management within higher education. More precisely, this thesis aims to increase the understanding of the scope and dimensions to be considered by universities when preparing and planning for a potential crisis. A qualitative study with abductive reasoning has been conducted to fulfill the purpose of this t
This essay introduces the sequential Good-Turing estimator and reviews the Good-Turing, Good-Toulmin and smoothed Good-Toulmin estimators. Some theoretical properties and drawbacks of the estimators are described. MonteCarlo simulation is then used to compare the performance of the sequential Good-Turing estimator to the performance of the Good-Toulmin estimator along with the smoothed Good-Toulmi
Strategic alignment has been a top concern for executives for the past two decades. The study aims to investigate how the social dimension of strategic alignment is perceived between an IT department and business department. The study consist of three phases, where the first phase includes two semi-structured interviews to define the problem area at the company in focus. By linking the answers giv
It is increasingly agreed upon by both scholars and policymakers that policies have different gendered effects. Agricultural input subsidies are highly debated policies in Africa. They were popular in the 1960s and 1970s, removed under the SAPs and liberalisation schemes in the 1980s and 1990s, and have been making a comeback since the turn of the century. This study aims to analyse to what extent
Following the increasing sustainability trend and awareness, investors now look beyond only financial considerations when purchasing stocks. This paper analyzes the relationship between Environmental, Social, Governance (ESG) scores and stock performance, measured by returns. It investigates if splitting the sample period would result in a different magnitude of abnormal returns. This study furthe
Bolsa Família is one of the largest conditional cash transfer programs in the world. It provides cash transfers to poor households, conditional on human capital requirements such as minimum school attendance. The literature emphasizes that more schooling increases the human capital formation of children, which leads to improved employment outcomes and will break the inter-generational transmission
