Introduction: There is a need for risk stratification of emergency department (ED) chest pain patients. The Global Registry of Acute Coronary Events risk score (GRACE RS) predicts adverse events in patients with confirmed acute coronary syndrome (ACS), and has been validated on unselected ED patients with chest pain. Clinical gestalt is the unstructured overall clinical assessment, based on the ph

Global warming and energy shortage have aroused a great interest in climate responsive strategies of vernacular dwellings during recent years. This study focuses on a qualitative analysis of ancient dwellings located in the village of Xinye, in the hot summer and cold winter region of China. Furthermore, a typical ancient dwelling located in the village was selected for assessment of its indoor th

The integration of scheduling and control in the process industry is a topic that has been frequently discussed during the recent years, but many challenges remain in order to obtain integrated solutions that may be implemented at large-scale industrial sites. This paper introduces a general framework for production scheduling (PS) and detailed production scheduling (DPS) using a two-level hierarc

Powders are widely used in pharmaceutical applications and understanding their nature is an important aspect of making successful formulations. Powder flowability describes the behaviour of powders and can be measured using several different methods. This study looks at the techniques: angle of repose and tapped density, comparing them to each other and looking at how consistent they are with chan

During the last decades Sweden’s security and defence policy has gone through many great changes. The official direction was, up until 2009, neutrality. This was then changed to solidarity in conjunction with the enactment by the Swedish government of the Solidarity Clause of the Treaty of Lisbon in the Swedish defence proposal. The change can be supposed to have affected other defence bodies, for

Biometric recognition systems are widely used to recognize an individual. Fingerprints is a biometric identifier and are today widely used in smartphones for biometric recognition. The fingerprint software used in smartphones are great and fast, and usually implemented for one person usage. A fingerprint software used for smartphones often conducts a one-to-one comparison between the sample and th

In the middle of the 19th Century the American Henry Thoreau famously did an act of what we today call Civil Disobedience. Since then he has inspired lots of people with his act and today it has become a known and discussed phenomenon. In this thesis I’ll examine the phenomenon civil disobedience. I use a normative study to analyse whether you, from a feminist perspective, can justify three specif

The purpose of this study was to gain a deeper understanding of how Swedish Migration agency and Swedish Migration courts reasoned regarding sexuality, gender identity and persecution within the home country in asylum assessments of LGBTQ+ people through a qualitative analysis of court decisions. Within this study fifteen court decisions have been analysed, all of which judgments relied on grounds

The aim of this thesis is to investigate the micro mechanical damage and the failure of paperboard during sharp edge cutting. Tetra Pak is at the very forefront of the food packaging industry and in order to keep this market position, continuous improvements are of great importance. Increased understanding of paperboard behaviour is a driving factor for these improvements, since it enables more ac

Arbete på distans blev under en period vardag för flera tjänstepersoner till följd av covid-19 pandemin. Huruvida arbete från den traditionella arbetsplatsen fortsättningsvis är önskvärd för medarbetarna kan tänkas vara av intresse för arbetsgivare att ha kännedom om. Syftet med studien var att undersöka medarbetares upplevelse av distansarbetet utifrån produktivitet och gruppsammanhållning för tiDue to the covid-19 pandemic telework became a regular workday for many white-collar workers during a period of time. Whether the traditional workplace is desirable for workers to be continued working from or not may be of interest to employers to know. The aim of this study was to examine how municipal workers in the white-collar sector experienced telework as well as perceived their productivit

The expected increase in both consumption and production of electricity strains the Swedish electricity grid, necessitating both reinforcement and expansion. Concurrently, the need to decarbonise heavy industry is becoming more urgent to achieve the EU Climate neutrality goal by 2050, with hydrogen anticipated as a key player. Hybrid energy systems that combine the generation of renewable electric

Background The Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) creatinine equation is routinely used to assess renal function but exhibits varying accuracy depending on patient characteristics and clinical presentation. The overall aim of the present study was to assess if and to what extent glomerular filtration rate (GFR) estimation based on creatinine can be improved.MethodsIn a cro

Aims. We study the dynamics and growth of dust particles in circumstellar disks of different masses that are prone to gravitational instability during the critical first Myr of their evolution. Methods. We solved the hydrodynamics equations for a self-gravitating and viscous circumstellar disk in a thin-disk limit using the FEOSAD numerical hydrodynamics code. The dust component is made up of two

The analysis of iron, manganese and antimony in silicate glass is of great interest in chemistry, materials science, earth sciences and archaeological sciences. Yet, conclusions from different fields appear to be contradictory and many questions about redox reactions in glass remain. The purpose of this study is thus to discuss whether and how these multivalent elements interact in glass. Soda-lim

GPR30, or G protein-coupled estrogen receptor (GPER), is a G protein-coupled receptor (GPCR) that is currently attracting considerable attention in breast cancer and cardiometabolic regulation. The receptor was reported to be a novel membrane estrogen receptor mediating rapid non-genomic responses. However, questions remain about both the cognate ligand and the subcellular localization of receptor

Objectives We investigated gender differences in the association between mortality and general psychological distress (measured by 12-item General Health Questionnaire, GHQ-12), as an increased mortality risk has been shown in community studies, but gender differences are largely unknown. Setting We used data from a cross-sectional population-based public health survey conducted in 2008 in the Swe

Solitary plasmacytoma (SP) and plasma cell leukemia (PCL) are uncommon (3-6%) types of plasma cell disease. The risk of progression to symptomatic multiple myeloma (MM) is probably important for the outcome of SP. PCL is rare and has a dismal outcome. In this study, we report on incidence and survival in PCL/SP, and progression to MM in SP, using the prospective observational Swedish Multiple Myel
