Ignition and Flame Spread in Wood-Based Composites

This thesis investigates the ignition and flame spread behaviour of engineered wood-based materials, focusing on Medium-Density Fibreboard (MDF), Particleboard, Oriented Strand Board (OSB), and Plywood. Thermal properties, such as thermal conductivity and specific heat capacity, were analysed using Transient Plane Source (TPS) measurements. A new technique has been introduced for measuring thermal

Protein kinase C-inhibition reduces critical weight loss and improves functional outcome after experimental subarachnoid haemorrhage

Objectives: Subarachnoid haemorrhage (SAH) carries a high burden of morbidity and mortality. One in three patients develop vasospasm, which is associated with Delayed Cerebral Ischemia. The pathophysiology includes vasoconstrictor receptor upregulation in cerebral arteries. The protein kinase C – inhibitor RO-31-7549 reduces the expression of several vasoconstrictor receptors and normalizes cerebr

Two-year scale-up dissemination study of a multi-strategic community-wide intervention promoting physical activity : a single-arm pre-post hybrid effectiveness-implementation trial

Background: Intervention trials that have demonstrated significant effects may not always replicate those effects when scaled up. This study aimed to test whether scaling-up a successful cluster randomized trial (the COMMUNICATE study, 9 intervention communities), which promoted population-level physical activity (PA), could promote PA in a broader citywide setting (29 communities) after two years

Considering water-temperature synergistic factors improves simulations of stomatal conductance models under plastic film mulching

Accurately simulating stomatal behavior is crucial for understanding water, carbon, and energy fluxes between land and atmosphere. Given the significant impact of plastic film mulching on water and temperature, it is essential to incorporate water and temperature modifications into stomatal conductance models under these conditions. In this study, we evaluated three commonly used stomatal conducta

Tailored pseudopotentials for magnesium surface core level shift calculations

In x-ray photoelectron spectroscopy (XPS), identifying the origin of peaks in the spectrum can be guided by theory calculations. With density functional theory (DFT), using pseudopotentials, one can obtain the difference in photoelectron energy for electrons originating from atoms of different environments, for example surface and bulk atoms, and thus model the surface core level shift (SCLS) ener

Linguistic Foundations of heritage language development from the perspective of Romance languages in Germany

This paper discusses the role of different factors determining the linguistic competence of heritage speakers (HSs) based on examples from speakers who speak a Romance language (French, Italian, Portuguese, or Spanish) as heritage language (HL) and German as the environmental language. Since the relative amount of contact with the HL and the environmental language may vary during the acquisition p

Rehabilitation of dysphagia and voice problems following total laryngectomy

Objective: Determine participants’ satisfaction with rehabilitation following total laryngectomy (TL) and investigate associations between dysphagia, voice problems, and possible explanatory variables. Methods: 172 Danish and Swedish participants having received a TL 1.6–18.1 years ago for laryngeal/hypopharyngeal cancer answered a questionnaire regarding satisfaction with rehabilitation following

Transport of Dipolar Excitons at the Type-II Polytype Interface of InP Platelets

The pursuit of high charge carrier mobility in nanostructures is crucial for advancing both device development and exploring fundamental physics. This study focuses on minimizing scattering to achieve high mobility, employing a polytype type-II interface formed between wurtzite and zincblende InP. On the zincblende side, electrons accumulate, while holes gather on the wurtzite side, resulting in t

Drivers of soil health across European Union – Data from the literature review

Soil health in Europe has reached a critical point: it is estimated that 60-70% of European soils are unhealthy. Changes in land use, its intensity and the quality of management have significant impacts on soil health and soil related ecosystem services. A systems analysis of soil health dynamics requires an understanding of the drivers inducing changes in land use and management. The DPSIR framew

Autoimmune effector mechanisms associated with a defective immunosuppressive axis in immune thrombocytopenia (ITP)

Immune thrombocytopenia (ITP) is an autoimmune disease characterized by an isolated thrombocytopenia and variable phenotype as some patients suffer no bleeding whilst others have bleeding from mild to severe, which may be fatal. This variability probably reflects the disease's complex pathophysiology; a dysregulated hyperreactive immune effector cell response involving the entire adaptive immune s

Associations between hand osteoarthritis, obesity and lipid metabolism : a cross-sectional study of the Halland County Osteoarthritis (HALLOA) cohort

Background: To determine whether obesity and markers of lipid metabolism are associated with radiological hand osteoarthritis (OA) in the Halland County Osteoarthritis (HALLOA) cohort. Methods: In this cross-sectional study, we included 231 participants aged 30–65 from the HALLOA cohort, which began in 2017 and is ongoing. Hand OA was defined as ≥ 2 joint groups (distal interphalangeal, proximal i

Implementering av AI för driftoptimering i kommersiella fastigheter

Följande studie är en fallstudie om implementering av AI för att driftoptimera styrsystem i kommersiella fastigheter, med fokus på fastighetsägares perspektiv. Studien har genomförts för att uppfylla två huvudsakliga syften. Del ett är att undersöka hur AI kan bidra till minskad energiförbrukning och förbättrad drift i kommersiella byggnader, och vilka incitament som finns för att implementera denThis study is a case study on the implementation of AI for optimizing building management systems in commercial real estate, with a focus on the perspective of property owners. The study addresses two main objectives. The first is to explore how AI can reduce energy consumption and improve building operations, as well as the incentives for adopting such technology. The second is to analyze the org

The analytical and clinical validity of AI algorithms to score TILs in TNBC : can we use different machine learning models interchangeably?

Background: Pathologist-read tumor-infiltrating lymphocytes (TILs) have showcased their predictive and prognostic potential for early and metastatic triple-negative breast cancer (TNBC) but it is still subject to variability. Artificial intelligence (AI) is a promising approach toward eliminating variability and objectively automating TILs assessment. However, demonstrating robust analytical and p

Hawaiiskjortans estetik

En kulturhistorisk perspketivering med plagget Hawaiiskjortan i fokus. Dels beskrivs Hawaiiskjortan som sådan, historisk etablering, i ett internetaionellt såväl som inrikes svenskt läge; dels förs resonemang om Hawaiiskjortans symboliska och betydelseproducerande roll i populärkulturen (TV-serier, filmer, musik av olika slag).

Distributions conditioned on extrapolated events via copula and extreme value theory

In an interaction between road users, the proximity and speed are two interdependent dimensions which can be captured by a type of multivariate distribution called Copula. Copula requires all marginal distribution functions to be known. However, finding the marginal distribution of the proximity dimension is challenging, as its histogram usually contains several peaks. We partition the outcome spa

Driving Forces and Enablers for Universal Design in Urban Planning

The built environment is still, to a large extent, not accessible and usable for all. The awareness of people's different conditions and abilities sometimes seems to be far from the agenda for planning and architecture. Universal Desing (UD) is pointed out as a strategy to achieve a built environment for all people regardless of age and abilities. UD has a radical potential to bring about change a

Polarization position angle standard stars : a reassessment of θ and its variability for seventeen stars based on a decade of observations

Observations of polarization position angle (θ) standards made from 2014 to 2023 with the High Precision Polarimetric Instrument (HIPPI) and other HIPPI-class polarimeters in both hemispheres are used to investigate their variability. Multiband data were first used to thoroughly recalibrate the instrument performance by bench-marking against carefully selected literature data. A novel co-ordinate
