Avsikten med detta projekt har varit att utveckla väl fungerande rutiner för PIXE-analys av biologiska prov med anknytning till exponering i arbetsmiljösituationer. Kravet på metoderna är att de tillvaratar PIXE-metodens fördelar (multielementanalys, små prov, snabb analys, låga detektionsgränser) och samtidigt förändrar eller förstör så lite som möjligt av den information som finns i de ursprungl

Popular Abstract in Swedish Den vanligaste lokalisationen för bråck eller aneurysm på stora kroppspulsåderns (AAA) är i buken nedanför njurpulsådrorna. Mellan 3-6% av befolkningen över 65 års har detta och det är vanligare hos män jämfört med kvinnor (3:1). Majoriteten av bråcken är asymptomatiska och upptäcks som ett bifynd isamband med undersökning för mag eller ryggbesvär. Ca ¼ av bråcken debutAIM: The aim was to evaluate the results of endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAA) in terms of intra-AAA pressure and clinical outcomes. METHODS AND RESULTS: 0.014-inch guide-wire-mounted tip-pressure sensors were used for direct intra-aneurysm sac pressure measurement (DISP) through translumbar puncture of the AAA. Mean Pressure Index was calculated (MPI) as the p

Do all humans perceive, think and talk about tree cover (‘forests’) in more or less the same way? International forestry programs frequently seem to operate on the assumption that they do. However, recent advances in the language sciences show that languages vary greatly as to how the landscape domain is lexicalized and grammaticalized. Different languages segment and label the large-scale environ

Stretching DNA in nanochannels allows for direct, visual studies of genomic DNA at the single molecule level. In order to facilitate the study of the interaction of linear DNA with proteins in nanochannels, we have implemented a highly effective passivation scheme based on lipid bilayers. We show long-term passivation of nanochannel surfaces to several relevant reagents and demonstrate that the pe

We have built an array of vertical nanotubes connected by a subsurface nanofluidic channel. The nanotube system is to be used for cell injections. By culturing cells on top of the nanotubes the cells will be pierced and molecules can enter the cells via the subsurface channel. Several channels can be made on the same sample and different molecules can be injected into different subpopulations of c

Purpose: The eyelid is commonly dissected and divided in the process of, for example, blepharotomy, entropion repair, or when preparing a full-thickness eyelid flap to reconstruct a tumor defect. No study has yet been conducted to examine how perfusion in an eyelid is affected by dissection, using modern imaging techniques. Methods: The eyelid was divided with a 10-mm vertical incision, 5 mm from

Sustainability science emerged as a new academic field to address complex sustainability challenges. To train sustainability experts, sustainability science programs and sustainability-focused courses are offered in higher education, especially at the graduate level. Given the diverse topics and the complex structures of sustainability challenges, what are the required knowledge and skills needed

If we admit that, with the exception of language, human perception is predominantly visual, it is reasonable to think that all phenomena conveyed by the visual senses have something in common, but then visual semiotics/visual culture will comprehend much more than painting, sculpture, and architecture. The double coding hypotheses of cognitive psychology, as well as Lessing’s classical opposition

The purpose was to study age related changes in circulatory system via Ballistocardiography (BCG) by utilizing Electromechanical Film (EMFi) sensors by gradually changing the ambient temperature from a thermoneutral area to cold direction. ECG and BCG were recorded from a young person (23 years) and from an older person (78 years), both males. During the tests, brachium blood pressure (BP) and pul

Background:: Those who are seriously ill and facing death are often living with physical, emotional, social, and spiritual suffering. Teamwork is considered to be necessary to holistically meet the diverse needs of patients in palliative care. Reviews of studies regarding palliative care team outcomes have concluded that teams provide benefits, especially regarding pain and symptom management. Muc

Bygg- och fastighetssektorn står för en betydande andel av Sveriges och EU:s totala växthusgasutsläpp, och tillverkningen av betong är en av de mest utsläppsintensiva delarna av byggprocessen. Med bakgrund av ökade klimatkrav undersöker denna studie förutsättningarna för återbruk av större betongelement i svenska byggprojekt. Studien analyserar den miljömässiga lönsamheten i återbruk, identifierarThe construction and real estate sector accounts for a significant share of Sweden's and the EU's total greenhouse gas emissions, and the production of concrete is one of the most emission-intensive parts of the construction process. Against the backdrop of increasing climate requirements, this study examines the conditions for reusing larger concrete elements in Swedish construction proje

This report describes and addresses patterns of discrimination in Sweden’s care sector, primarily related to gender and migrant status. It examines national legislation, collective agreements, case law, and equality bodies’ activities concerning equal treatment, pay transparency, parental leave, and occupational safety. It highlights the highly feminised nature of the care workforce, persistent ge

Lagen (1982:80) om anställningsskydd (LAS) genomgick år 2022 en reform som bland annat innebar en förändring av regleringen för uppsägning på grund av personliga skäl i 7 § LAS. Syftet var att öka förutsebarheten för både arbetsgivare och arbetstagare vid uppsägningar. Med hjälp av rättsdogmatisk metod syftar uppsatsen till att analysera och kartlägga reformen i förhållande till uppsägning på gruThe Employment Protection Act (LAS) underwent a reform in 2022 which, among other things, involved a change in the regulation regarding dismissals on personal grounds in Section 7. The purpose of the reform was to increase predictability for both employers and employees in cases of dismissals. Using a legal dogmatic method, the thesis aims to analyse and map the reform in relation to dismissal on

Infectious diseases are the primary cause of mortality worldwide. The dangers of infectious disease are compounded with antimicrobial resistance, which remains the greatest concern for human health. Although novel approaches are under investigation, the World Health Organization predicts that by 2050, septicaemia caused by antimicrobial resistant bacteria could result in 10 million deaths per year
