Introduction: Validation of a new test method to determine nicotine from chewing gum extracts with ultra high-performance liquid chromatography. Background: In Quality Control-laboratories, the methods that are regularly used are consistently developed in order to conduct effective analysis procedures. The aim of all of these developments is to simplify the analysis as much as possible and make t

Thermal comfort is a topic that for the last century has interested designers and researchers. European and International standards have given guidelines for assessment of thermal comfort in typical indoor environments for long occupancy, however the transitory spaces and semi-external spaces have not been addressed. Available literature was reviewed and summarize to find appropriate methods for a

The new CZT camera has a different technology compared to conventional scintillation gamma cameras. The CZT camera have pinholes instead of parallel hole collimators, a static gantry instead of a rotating one and detection material made of a semiconductor in- stead of a scintillation crystal. The images arising from the CZT camera have a difference in appearance compared to the images produced by

Simulations of domains with large differences in length scales across different directions are often computationally expensive because they require high mesh resolution, leading to long simulation times. This master’s thesis was done in collaboration with FS Dynamics Sweden AB and addressed the high computational cost associated with fully resolved 3D simulations. Inspired by semiconductor and ele

The number of openly outed trans individuals in society and in sport is increasing and can be expected to keep growing. The sporting domain is singled out as special in terms of trans rights, as it is solely based on physical characteristics. Trans people in sport have become a subject of heated debates. However, the field of human rights has so far neglected the topic. Analysing 16 transgender el

The need for speed in communications systems is increasingly prevalent in modern society, which is one of the driving factors for the evolution of new technologies. At the forefront of this evolution are Multiple-input Multiple-output (MIMO) systems. Through the usage of many antennas at the base station (BS) and user equipment (UE), significantly enhances the potential maximum data transfer rates

This paper investigates the possibility of using empirical tool life models to predict tool life in a side milling application in a medium carbon steel, C 45E. To do this, an extensive dataset containing 46 data points with different machining parameters are produced. Four different empirical models: Taylor's equation, Colding's equation and Extended Taylor both using depth of cut and feed as well

Background: Patients with severe asthma may present with characteristics representing overlapping phenotypes, making them eligible for more than one class of biologic. Our aim was to describe the profile of adult patients with severe asthma eligible for both anti-IgE and anti-IL5/5R and to compare the effectiveness of both classes of treatment in real life. Methods: This was a prospective cohort s

Introduction Firefighters have increased risk of chronic respiratory disease. Standard clinical techniques used in medical checkups may not detect the earliest microstructural changes in peripheral airways. A new technique called Airspace Dimension Assessment (AiDA) has been shown to enable early detection of emphysema in COPD. This method may be useful in the occupational setting to detect early

Purpose: Flattening filter free (FFF) beams generated by medical linear accelerators have recently started to be used in radiotherapy clinical practice. Such beams present fundamental differences with respect to the standard filter flattened (FF) beams, making the generally used dosimetric parameters and definitions not always viable. The present study will propose possible definitions and suggest

The serum immunoglobulin-free light chain (FLC) assay measures levels of free kappa and lambda immunoglobulin light chains. There are three major indications for the FLC assay in the evaluation and management of multiple myeloma and related plasma cell disorders (PCD). In the context of screening, the serum FLC assay in combination with serum protein electrophoresis (PEL) and immunofixation yields

BACKGROUND: Rare locations of hernias, as well as primary ventral hernias under certain circumstances (cirrhosis, dialysis, rectus diastasis, subsequent pregnancy), might be technically challenging. The aim was to identify situations where the treatment strategy might deviate from routine management. METHODS: The guideline group consisted of surgeons from the European and Americas Hernia Societies

Background: Hypoxic-ischaemic encephalopathy (HIE) is a leading cause of mortality and long-term neurological sequelae, affecting thousands of children worldwide. Current therapies to treat HIE are limited to cooling. Stem cell-based therapies offer a potential therapeutic approach to repair or regenerate injured brain tissue. These preclinical findings have now culminated in ongoing human neonata

Background and purpose — Studies describing time-related change in reasons for knee replacement revision have been limited to single regions or institutions, commonly analyze only 1st revisions, and may not reflect true caseloads or findings from other areas. We used revision procedure data from 3 arthroplasty registries to determine trends and differences in knee replacement revision diagnoses. P

This thesis examines how sustainability is prioritised politically and integrated in the Danish municipal primary and lower secondary education. It consults representatives from the Ministry of Education, the unicipality of Copenhagen and ten lower secondary education teachers about their perceptions of sustainability and education and their experiences with integration of sustainability education
