Detta examensarbete utfört på uppdrag av och i samarbete med Vossloh Nordic Switch Systems AB i syfte att ta fram ett pressverktyg för montering av fjäderbefästningar (s.k. pandrolfjädrar) vilka används vid installation av järnvägsväxlar. Det verktyg som huvudsakligen används idag har inte kunnat brukas till hela produktportfolion av växlar på grund av verktygets storlek som inte tillåter åtkomst This master thesis work was carried out on behalf of and in collaboration with Vossloh Nordic Switch Systems AB with the aim of developing a pressing tool for the assembly of spring fasteners (so-called Pandrol e-clips) used in the installation of railway switches. The tool primarily used today has not been able to be used for the entire product portfolio of switches due to the tool’s size, which

The increasing presence and activities of people in both urban environments and non-urban areas result in the exposure of many wild animal populations to persistent human disturbance. As a response, individuals in disturbed populations often become tolerant towards humans, which can have significant ecological and societal consequences, for example by affecting ecosystem services and human–wildlif

This paper examines digital wellbeing as an evolving, mul-tifaceted concept shaped by technological design, data practices, and policy measures. Focusing on children and young people, it explores how digital wellbeing is governed through individual, platform, and government regulation. The technological dimension is foregrounded through well-being management tools such as screen-time dashboards, a

Population growth and climate change have accelerated groundwater depletion globally. Interferometric synthetic aperture radar (InSAR) is a fairly new satellite remote sensing technique based on SAR images that offers a high-accuracy monitoring system of land surface motion driven by groundwater level changes in time and space that can never be achieved with point-in-situ measurements. In producti

Telomere length (TL) early in life often shows high heritability and may predict telomere shortening later in life and life expectancy. Yet, there is limited data about what influences TL and TL change at early developmental stages. It is debated whether early-life TL is determined at conception or shaped by early environmental conditions. Here, we investigate whether TL and telomere shortening ar

Hur skapar man samsyn och samarbete i en kommunal koncern där förvaltningar tidigare tänkte i stuprör? I Höganäs växte en kultur av gemensamt ansvar fram genom vardagliga berättelser och budgetprocessen. Den här artikeln berättar historien om hur kommunen etablerade en koncernledningsgrupp för att styra sin samlade verksamhet. Eller var det egentligen en koncernkultur som växte fram?

Årsredovisningens förvaltningsberättelse är mer än formaliteter. Den ska ge en tydlig bild av verksamheten och ge underlag för framtida beslut. Här finns stora möjligheter att höja kvaliteten ytterligare. Forskare vid Ekonomihögskolan, Lunds universitet, ger konkreta tips för hur berättelsen kan bli tydligare och mer användbar.

Background: In axial spondyloarthritis (axSpA), 5–10% of patients have comorbid inflammatory bowel disease (IBD). Beyond that, 50–60% display histologic inflammation in ileum/colon biopsies, and fecal calprotectin (F-calprotectin) is elevated in relation to healthy controls. Prior studies have shown such, often subclinical, gut inflammation in axSpA to be associated with more active disease, as me

"Jag har ombetts förmedla de synpunkter jag presenterade som ledamot av betygsnämnden vid Sameh Egyptsons disputation vid Centrum för Teologi och Religionsvetenskap (CTR), Lunds universitet, den 10 februari 2023. Det är inte brukligt att göra så. En disputation är och skall vara en offentlig och transparent process – men inte bedrivas via medierna. Det är heller inte syftet här. Disputationen är g

The observation of the electroweak production of single-top-quarks is made using 255 pb−1 of proton-proton collision data recorded at s=5.02 TeV with the ATLAS detector at the Large Hadron Collider. An event selection is used to identify single-top-quark candidates arising from t-channel production with the top quark decaying semi-leptonically. Events passing the selection are then used to measure

Over geologic time, biocalcification – the process by which marine organisms make calcium carbonate (CaCO3) – has reshaped climates, ocean life, and seawater chemistry. In particular, the evolution of coccolithophores, the largest group of nannoplankton and today’s most productive calcifiers, transformed ocean environments and the carbon cycle. Their origins, however, remain enigmatic. This is par

Background: Regular, detailed reporting on population health by underlying cause of death is fundamental for public health decision making. Cause-specific estimates of mortality and the subsequent effects on life expectancy worldwide are valuable metrics to gauge progress in reducing mortality rates. These estimates are particularly important following large-scale mortality spikes, such as the COV

Background: Understanding the health consequences associated with exposure to risk factors is necessary to inform public health policy and practice. To systematically quantify the contributions of risk factor exposures to specific health outcomes, the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 aims to provide comprehensive estimates of exposure levels, relative health r
