The purpose of this work was to study how the pixel size of digital detectors can affect shape determination of microcalcifications in mammography. Screen-film mammograms containing microcalcifications clinically proven to be indicative of malignancy were digitised at 100 lines/mm using a high-resolution Tango drum scanner. Forty microcalcifications were selected to cover an appropriate range of s

Studien presenterar en utvärdering av SI-verksamheten vid fem civilingenjörsprogram vid LTH baserat på data från enkäter till SI-deltagare och SI-ledare, genomströmningsdata för nybörjarstudenter på kurs- samt läsårsnivå, samt nybörjarstudenternas betyg från gymnasiet. Resultaten visar på att deltagande på SI-övningar ger en ökad genomströmning på både kurs- och läsårsnivå. Vidare finns tydliga in

Popular Abstract in Swedish Människan har under mycket lång tid använt enzymer vid tillverkning av livsmedel, bland annat vid syrning av mjölk, jäsning av bröd och bryggning av öl och vin. Man använde sig då av hela levande organismer och först på slutet av 1800-talet kunde den aktiva substansen isoleras. Dessa aktiva substanser fick samlingsnamnet enzym, vilket kommer från grekiska och betyder "iThe influence of different reaction parameters on enzyme selectivity was investigated. The reaction conditions studied were solvent dependence, water activity and reaction temperature. The improved selectivity was observed as higher synthetic yields in a-chymotrypsin and subtilisin catalyzed peptide synthesis respectively, and as higher enantioselectivity in the asymmetric reduction of ketones cat

Popular Abstract in Swedish Nedisningar under Weichsel-istiden kring floden Notec i nordvästra Polen. Inlandsisar är en viktig komponent i jordens klimatsystem. Deras utbredning och rörelsemekanismer styrs till stor del av klimatet samtidigt som isarna i sin tur också påverkar klimatsystemet. Genom kunskap om hur inlandsisarna växte till och smälte av under den senaste istiden kan man utvärdera oThis thesis presents results of studies on the ice flow pattern and ice movement mechanism during the Weichselian glaciations in the middle Notec River area, NW Poland. A new lithostratigraphy of the study area has been established, based on correlation of stratigraphical position, clast lithology, fabrics and grain size composition of till units. The lithostratigraphy covers two glacial advances

The Euro50 is a European Extremely Large Telescope. Its enclosure will be among the largest buildings of the world. Determining the maximum wind load is crucial for the survival of the structure, and local forces have an impact on the detailed design such as cladding. Pressure variations on the primary mirror and the wind load on the telescope are important for the development of active optics and

Frostnedbrytning av betong kan få allvarliga konsekvenser för en konstruktions säkerhet, beständighet och funktionsduglighet eftersom betongens hållfasthet försämras. Frostskador uppstår vanligtvis i konstruktioner med hög fuktbelastning och som periodvis utsätts för frostangrepp. Olika typer av betongskador, vilka kan misstänkas vara frostrelaterade, har påträffats i svenska vattenkraftsanläggninFrost deterioration of concrete can result in severe consequences to the safety, durability and functionality of a structure since it impairs the strength of the concrete. Frost damage may occur to structures that are in contact with water and subjected to frost action. Different types of concrete damage, which are suspected to be frost related, have been observed in concrete structures in Swedish

Previous findings suggest a link between neuroinflammatory processes and suicidality. Despite several lines of evidence supporting this link, including increased pro-inflammatory markers in blood-, cerebrospinal fluid (CSF)- and in post-mortem brain samples from suicidal individuals, the underlying mechanisms remain poorly understood. In this pilot study, we explored the possibility that autoimmun

Background: The path between patients and health care providers has adopted new advanced information technologies. However, opinions vary about the digital care meeting. Physicians have expressed concerns about increased workload, changes in working methods, and information security. Purpose: To explore physicians’ experiences and satisfaction of digital primary health care. Method: A convergent m

Desalination is an important method for producing drinking water and it has been a freshwater supply alternative for a long time. The water resources in the Gulf Cooperation Council (GCC) countries, are mostly depending on desalination as a major source of (>80 %) drinking water, while the rest comes from groundwater. The largest number of desalination project is located in the Gulf countries (Sau

Research shows that resistance to change might occur in organisations that implement new evidence-based practices (EBP). Formal and informal structures may work to retain traditional interventions, potentially counteracting the implementation process. Little is known about the de-implementation of traditional practices to leave room for and enhance the implementation of EBPs. This study uses imple

Loneliness in advanced age has become one of the societal concerns considering its detrimental effects on physical and mental health of older people. Information and communication technologies show the potential to prevent or tackle loneliness and social isolation among older people. Given a percentage of the older population feeling lonely, loneliness in older age has been increasingly recognized

Background The coronavirus disease 2019 (COVID-19) pandemic has put pressure on healthcare services, forcing the reorganisation of traditional care pathways. We investigated how physicians taking care of severe asthma patients in Europe reorganised care, and how these changes affected patient satisfaction, asthma control and future care. Methods In this European-wide cross-sectional study, patient
