Purpose The purpose of this study was to investigate, in a nationwide study, the inter-observer variation and performance in interpretations of bone scans regarding the presence or absence of bone metastases. Methods Bone scan images from 59 patients with breast or prostate cancer, who had undergone scintigraphy due to suspected bone metastatic disease, were studied. The patients were selected to
Three approaches to trend analysis of water quality time series are discussed: (1) seasonal model, with a test for trend based on ranks of observations, with observations assumed to be m dependent; (2) transfer function noise model, in which covariate series may be included by means of transfer functions, with the remaining noise modeled as a seasonal autoregressive moving average process; and (3)
Laser-induced fluorescence is a powerful measurement method for determining the concentration of organic pollutants as well as the amount of algae in water. It can be applied in remote sensing of natural waters and has the advantages of high speed and sensitivity. In this paper, we present a compact handheld fluorosensor system for water quality assessment. The power of the technique is demonstrat
Instruments related to work are commonly illuminated from an ill-health perspective. The need for a concise and useable instrument in workplace health promotion governed the aim of this paper which is to present the development process and quality assessment of the Work Experience Measurement Scale (WEMS). A survey, using a questionnaire based on established theories regarding work and health, and
Multiple sequence alignment is the foundation of many important applications in bioinformatics that aim at detecting functionally important regions, predicting protein structures, building phylogenetic trees etc. Although the automatic construction of a multiple sequence alignment for a set of remotely related sequences cause a very challenging and error-prone task, many downstream analyses still
Psoriasis is a common, chronic disease and in one-third of the patients it begins during the first 2 decades of life. The burdens of psoriasis are many, and some can be assessed with quality of life questionnaires. The aim was to investigate the impact of childhood psoriasis on quality of life in children and their parents and to correlate certain clinical findings with quality of life. Forty-five
BACKGROUND: New developments in processing of digital radiographs (DR), including multi-frequency processing (MFP), allow optimization of image quality and radiation dose. This is particularly promising in children as they are believed to be more sensitive to ionizing radiation than adults. OBJECTIVE: To examine whether the use of MFP software reduces the radiation dose without compromising qualit
The transition from batch-wise to integrated continuous manufacturing of biopharmaceuticals has gained significant attention over the past decade. While this concept has been thoroughly studied, there remains significant room for improvement in terms of process automation and real-time monitoring. This study showcases the implementation of an integrated downstream process at a lab scale, operating
Abstract in UndeterminedThe hitherto most successful theory explaining why similar industrialized market economies have developed such varying systems for social protection is the Power Resource Theory (PRT), according to which the generosity of the welfare state is a function of working class mobilization. In this paper, we argue that there is an under-theorized link in the micro-foundations for
BACKGROUND: Current health measurement instruments tend to measure aspects of ill-health rather than health in general. There is a need for a salutogenic perspective when describing health and developing a health measurement instrument. The aim of this article is to present the development process and quality assessment of a salutogenic health indicator scale. METHODS: A description of health, ema
Achieving good acoustic particle or cell separation performance requires skilled operators, who must carefully fine-tune the input parameters (actuation voltages, flow rates, and flow split ratios). Often the fine-tuning is done by time-consuming parameter sweeps, which are tedious and expensive. Here, we present a straightforward model-based approach to determining input parameters that yield opt
It is well-documented that male overweight and obesity causes endocrine disorders that might diminish the male reproductive capacity; however, reports have been conflicting regarding the influence of male body mass index (BMI) on semen quality and the outcome of assisted reproductive technology (ART). The aim of this study was to investigate whether increased male BMI affects sperm quality and the
