The road safety barriers are today designed and installed in compliance with the European standards for Road Restraint Systems (EN 1317), which lays down common requirements for the testing and certification in all EU countries. The introduction of the European Union (EU) regulation for safety barriers, which is based on performance, has encouraged European road agencies to perform an upgrade of t
Purpose – The purpose of this paper is to increase understanding of the use of standards and modularity for improving responsiveness in the humanitarian context. Design/methodology/approach – Based on a conceptual framework and a systematic literature review, the authors conducted a longitudinal, explorative case on the Emergency Response Unit (ERU) concept in the International Federation of Red C
In this study, a sampling and analysis tool for aerosol particles has been developed. Its purpose is to characterize upper tropospheric aerosols, where concentrations are low. Since measurements will be made from an airplane, a time resolution of one hour is desirable. These conditions require efficient sampling and analysis with low detection limits. To accomplish this, our sampler uses impaction
Avian migrants may fly at a range of altitudes, but usually concentrate near strata where a combination of flight conditions is favourable. The aerial environment can have a large impact on the performance of the migrant and is usually highly dynamic, making it beneficial for a bird to regularly check the flight conditions at alternative altitudes. We recorded the migrations between northern Europ
Context. It has recently been suggested that all giant stars with masses below 2 M? suffer an episode of surface lithium enrichment between the tip of the red giant branch (RGB) and the red clump (RC). Aims. We test if the above result can be confirmed in a sample of RC and RGB stars that are members of open clusters. Methods. We discuss Li abundances in six open clusters with ages between 1.5 and
Insulin resistance causes compensatory insulin production, which in humans can eventually progress to β-cell failure and type 2 diabetes (T2D). This disease progression involves multi-scale processes, ranging from intracellular signaling to organ and whole-body level regulations, on timescales from minutes to years. T2D progression is commonly studied using overfed and genetically modified rodents
AIMS: Selecting patients for cytoreductive surgery and hyperthermic intra-peritoneal chemotherapy (HIPEC) remains challenging. We compared the predictive power of three intra-operative assessment tools of peritoneal involvement of colorectal cancer.METHODS: Ninety-two procedures (1999-2005) were prospectively scored using the Simplified Peritoneal Cancer Index (SPCI) and 7 Region Count. The Perito
Aims: Newly-defined subgroups of type 2 diabetes mellitus (T2DM) have been reported from real-world cohorts but not in detail from randomised clinical trials (RCTs). Methods: T2DM participants, uncontrolled on different pre-study therapies (n = 12.738; 82 % Caucasian; 44 % with diabetes duration > 10 years) from 14 RCTs, were assigned to new subgroups according to age at onset of diabetes, HbA1c,
UNLABELLED: Studies investigating the immunogenicity of additional COVID-19 vaccine doses in immunosuppressed patients with inflammatory rheumatic diseases (IRD) are still limited. The objective was to explore the antibody response including response to omicron virus subvariants (sBA.1 and sBS.2) after third and fourth COVID-19 vaccine doses in Swedish IRD patients treated with immunomodulating dr
Objective: This study aimed to report the initial experience with a novel bidirectional double cuff inner branch design for incorporation of renal and mesenteric arteries in patients undergoing fenestrated and branched endovascular aortic repair (F/BEVAR). Methods: A retrospective review was undertaken of the experience of F/BEVAR with grafts integrating at least one bidirectional double cuffed in
When automating data analysis or broadcasts in association football, a key piece of information is the position of the football. Locating the ball is often easier said than done since there are many scenarios where the ball is hard or even impossible to detect accurately using object detection methods. This thesis explores a different approach to determining the ball's position. Since the play
This master’s thesis is commissioned by SAAB Group with the purpose of developing a model which can be used to estimate the margin for expansion of devices in PLC systems. Although commercial PLC systems are hard real-time systems, they have inherited unpredictable characteristics due to off-the-shelves components. This makes it difficult to measure the impact on performance when a new device is c
Vätgas har potential i ett energilagringssystem eftersom det är en energibärare som är väldigt energirik och kan lagras i stor skala. Vätgas kan produceras enkelt via elektrolys av vatten och lagras i stora mängd under högt tryck, vid behov kan vätgasen sedan brännas i en kraftverksprocess och generera elektricitet. Då förbränning av vätgas med syrgas enbart bildar vattenånga kan ett förnybart eneHydrogen gas has potential to function as an energy storage solution due to its high energy content and its suitability for large scale storage. Hydrogen can be produced by water electrolysis and can be stored in large scale under high pressure, when needed the hydrogen can be burned in a thermal power plant to generate electricity. Since combustion of hydrogen with pure oxygen only yields steam,
In the realm of urban planning, urban greening – the creation or restoration of green spaces in cities – has risen as an attractive approach for policy-makers and planners engaged in sustainability. As the benefits of urban greening are many, from social and cultural to environmental and economic, it has become positioned as a win-win solution to several urban challenges related to sustainable dev
Denna uppsats undersöker hur fem icke-statliga organisationer (NGO) framställer händelserna kring Sea-Watch 3-fallet sommaren 2019. Räddningsfartyget hölls kvar till havs i över två veckor efter att ha undsatt migranter utanför Libyens kust, utan att någon stat erbjöd en säker hamn. Studien utgår från en kombination av två teoretiska ramverk: normmodellen och liminalitet. Normmodellen används för This thesis examines how five non govermental organisations (NGO) represent the events surrounding the Sea-Watch 3 case in the summer of 2019. The rescue vessel remained at sea for over two weeks after saving migrants off the coast of Libya, without any state offering a safe port of disembarkation. The study draws on a combination of two theoretical frameworks, the norm model and liminality. The n
In Sweden as well as in The Netherlands energy policy is increasingly aiming at extending the use of renewable sources. In accordance with the targets of the European Union, both countries have formulated national targets for the year 2020. For wind energy these targets are 30.0 TWh of electricity in Sweden and a total installed capacity of 10.0 GW in The Netherlands. Wind is an inflexible, variab
Skogsbruket är viktigt för svenskt näringsliv och står för ungefär 20 % av Sveriges totala export. Efterfrågan på virke blir därmed stor vilket resulterar i att avverkning sker ständigt, året om, på all typ av mark under alla olika sorters väderförhållanden. Ett stort problem inom skogsbruket är de markskador som ofta uppstår efter en slutförd avverkning. Markskador ändrar markens textur och egensForestry is important for Swedish industry and accounts for 20% of Sweden’s total export. The endless demand of wood results in logging all year round, but other aspects have to be taken into consideration. The ecology, forest recreation and the outdoor activities that the forest is providing is very important to preserve. A major problem in forestry is the soil damage after a successful harvest.
