Groundwater in most parts of the world is an important source of agricultural water supply for food production. Soil salinization, however, threatens groundwater quality and may cause irreparable damage to agricultural land. A key to tackling this threat is to analyze the link between agricultural crop water requirements and groundwater quality. This study aimed to investigate salinity effects on
Monitoring and characterizing melt pool dynamics in additive manufacturing is essential for understanding complex thermal and material behaviors that govern layer formation. Melt pool characteristics, such as size, shape, and dynamics, directly influence microstructure evolution, mechanical properties, and dimensional accuracy of the printed part. Therefore, accurate and efficient methods for melt
Sentinel lymph node biopsy (SLNB) remains the standard method for axillary staging in breast cancer. However,for the majority of patients with early breast cancer, it offers no treatment benefit and carries a risk of long-termside effects. In the era of surgical de-escalation, reliable preoperative assessment of axillary lymph node metastasis isessential to avoid overtreatment and support treatmen
Background: Adolescents are increasingly using classical psychedelics, yet little is known about how psychedelics use is related to their mental health. Emerging evidence suggests that adolescents may be more vulnerable to adverse outcomes in relation to psychedelic use compared to adults. This descriptive and exploratory study examined differences between adolescents and adults in reported psyche
Children undergoing surgery for posterior fossa tumours (PFT) may experience postoperative language and communication difficulties, regardless of whether they develop cerebellar mutism syndrome (CMS) or not. While these language difficulties are increasingly recognised in current research, children’s own experiences of everyday communication remain limited. In this presentation, we share findings
Atmospheric dispersion represents a relatively overlooked problem in connection with the ultimate quality of ELT images corrected by adaptive optics (AO). The aim of this paper is to evaluate the contribution from atmospheric dispersion to the background level of the point-spread function (PSF). Since proper suppression of this level is important for the prospects for direct exo-planet observation

In this paper, we present a new way to control linear stochastic systems. The method is based on statistical bootstrap techniques. The optimal future control signal is derived in such a way that unknown noise distribution and uncertainties in parameter estimates are taken into account. This is achieved by resampling from existing data when calculating statistical distributions of future process va
In this paper the heat losses from a novel type of district heating culvert, termed Elgotherm, is investigated and compared to conventional culvert. The insulation material is made of expanded polystyrene and the culvert consists Of four cross-linked polyethylene pipes. The heat losses are calculated using both a time dependent and a stationary finite element model. Measured data from an existing
Background: We aimed to study the long-term effect of smoking on coronary atherosclerosis progression at the segmental level. Methods: Angiographic data (1989-2017) on current, former, and nonsmokers were collected from the Swedish Coronary Angiography and Angioplasty Registry. The Western Denmark Heart Registry was used to validate the results. Patients with clinically indicated angiography with
Background: Rehabilitation is effective and beneficial for patients with arthritis. The lack of a common structure for describing the content of rehabilitation makes it difficult to compare, transfer and implement research evidence into clinical practice. Objective: To develop a framework comprising domains and elements of importance when describing arthritis rehabilitation. Methods: On the basis
Ökad konkurrens medför att företag måste förstå vilka framgångsfaktorerna är i deras bransch. Systems approach är ett bra verktyg för att identifiera möjligheter och för att skapa förståelse för vad som ligger bakom problem i värdekedjan. Användandet av olika metoder för att hantera materialflöden medför flera olika kombinationer av till exempel orderkvantitet och leveransfrekvens. Scania Producti
This thesis explores how the handling, analysis and transformations of material and data affect the production of knowledge in an applied project of cultural analysis. It concerns itself mainly with the process of dislocation, transformation and transportation of meaning, by putting to work the actor-network theories of Bruno Latour. An attempt will be made to retrace the steps of creating materia
As the quest for knowledge translation from research to practice and policy contexts is growing stronger, researchers need to develop strategies for synthesizing research findings. Since home environments constitute an important context for the delivery of health care and social services to older adults and people aging with disabilities, research in this field can serve as an example for such end
Introduction: Patients with midgut neuroendocrine tumours (NETs) suffer from decreased health-related quality of life (HRQoL), in large part due to bowel symptoms. However, it is unknown which bowel symptoms affect HRQoL the most. An enhanced understanding of this is essential to better focus treatment on this aspect of the disease. This study aimed to determine which bowel symptoms affect HRQoL t
Patients with advanced cancer and family caregivers in palliative care face physical, psychological, social and existential challenges, much of the time home alone. Specialist palliative home care team services can be instrumental for sense of security in an uncertain situation. The aim of this study was to describe patients’ and family caregivers’ experiences of specialist palliative home care te
