Many migratory animals use daylength, or photoperiod, to signal when to migrate and transition between annual phenological states. Whether animals use photoperiod as a temporal or spatial cue while migrating, however, requires additional empirical support. We used hatch-year dunnocks, Prunella modularis (a songbird), caught during their first migration in southern Sweden to elucidate whether migra
Framväxten av digitala plattformar håller för närvarande på att förändra hur kulturarbete förmedlas och utförs. Trots detta finns det en brist på forskning, inte minst i en svensk kontext, som studerar kulturarbete som ett typexempel på det som kommit att kallas gigarbete. Den här avhandlingen analyserar frilansande kulturarbetares erfarenheter av att navigera den digitala plattformsekonomin för aCultural industries are currently being transformed by processes of platformization and precarization. Despite being among the sectors where platformization has already had the most pronounced effects, there remains a lack of research on cultural work as a prototypical example of so-called gig work. This dissertation analyzes the working experiences of what I call digital freelancers — solo self-e
In Sweden, phosphorus is commonly removed from municipal wastewater treatment by chemical precipitation (CP). Recently, such alternatives as enhanced biological phosphorus removal (EBPR) have garnered interest due to the increased risk of chemical shortage. In this study, a life cycle assessment (LCA) was performed to compare EBPR and CP in three scenarios: 1) baseline – precipitation chemicals av
Background:Acute mesenteric venous thrombosis (MVT) is rarely suspected as primary diagnosis in emergency departments and still carries an in-hospital mortality rate of above 20%.Objectives:The aim of this study was to find differences in clinical and laboratory markers between patients with acute MVT and a control group of suspected but confirmed as not having any type of acute mesenteric ischaem
Objectives: To evaluate the feasibility of AI-assisted reading of prostate magnetic resonance imaging (MRI) in Organized Prostate cancer Testing (OPT). Methods: Retrospective cohort study including 57 men with elevated prostate-specific antigen (PSA) levels ≥3 µg/L that performed bi-parametric MRI in OPT. The results of a CE-marked deep learning (DL) algorithm for prostate MRI lesion detection wer
Objectives: This study examined long-term changes in body composition and bone mineral characteristics among male long-distance runners from a high-profile university team, focusing on concerns about impaired musculoskeletal development due to extreme leanness and weight management practices in this population. Methods: Trajectory analyses were performed using multilevel modeling of 608 dual-energ
Every year about 15 million people are injured in traffic, 500,000 of these fatally. Developing countries are badly affected. During the worst years of the war in Nicaragua, more people died in traffic accidents than as a direct result of the war. Transport system and infrastructure have developed rapidly in developing countries, while little has been achieved in preventing accidents or lessening
While several scholars do not consider the anointing of (the feet of) Jesus in Bethany described in the Gospel of John to carry any messianic connotations, some claim that a royal messianic notion is behind the anointing. The hypothesis of this paper is that the anointing is indeed to be understood as messianic, but that it is insufficient to consider only one Christological motif to be in the bac
EF-hand proteins are central in many cellular processes being the main group of Ca2+-sensing and buffering proteins in the cell. In the work presented in this thesis we study ligand interactions of three EF-hand proteins; calmodulin, calbindin D28k and secretagogin. We have developed a screening method using proteins arrays and validation of targets with surface plasmon resonance. With have applie
Flexible manufacturing puts high demands on industrial automation in terms of affordable and competitive solutions and is of key importance for short-lot production typically found in small and medium sized enterprises, situations where today manual labour is extensively used despite environmental issues and harsh working conditions. Key factors in the successful introduction of new robot automati
One of the common tools for studying the deformation behavior of the microstructure in polycrystalline materials is crystal plasticity models. These are used to describe texture evolution and hardening due to crystallographic slip. A drawback when using crystal plasticity models is that the calculation of the slip requires solving a set of stiff differential equations for each grain in the microst
Introduction: High-mobility group box 1 (HMGB1) is a non-histone nuclear protein and can be extracellularly secreted to induce sterile inflammation. Although uterine deletion of HMGB1 causes implantation and decidualization defects, how secreted HMGB1 is involved in mouse early pregnancy is still unknown. Methods: Mouse models, mouse primary endometrial cells and human endometrial cell lines were
Poor management and excessive pumping of groundwater (GW) resources can lead to a significant decline in GW level, which may result in land deformation and compaction of compressible fine-grained soils within or adjacent to the aquifer. Soil compaction and resulting land deformation may be permanent if the GW level declines beyond the maximum historical stress. In extreme cases, the aquifer may lo
Background: Obsessive-compulsive disorder (OCD) and co-occurring posttraumatic stress disorder (PTSD) is associated with more severe and chronic OCD. However, findings regarding treatment effectiveness of cognitive behavioral treatment (CBT) with exposure and response prevention (ERP) with this comorbidity are mixed. Research aimed at understanding the precise barriers to OCD treatment effectivene
