Sedan urminnes tider har frågor om etik och moral haft stor inverkan på människors liv. I den globaliserade och digitala värld vi idag lever i är dessa fortfarande aktuella, men har kommit att förändras. Då vi har gått från att befinna oss i en kollektiv till en konnektiv kontext, och vår kommunikation inte längre enbart sker ansikte mot ansikte, har nya etiska och moraliska frågor uppkommit. Den
Det är idag vanligt förekommande att företag nyttjar en så kallad cause branding strategy för att marknadsföra sina produkter. Detta gynnar ofta både försäljningen och bilden konsumenterna får av företaget (Persis Murray, 2012, s. 84). Cause branding strategies har utvecklats och förekommer idag genom olika metoder, så kallad varuaktivism. Denna uppsats syftar till att undersöka feministisk varuak
The following thesis examines the work of the early swedish transplant surgeons with special regards to the question of organ procurement. Through a careful reading of letters during 1971-1986, left from one prominent swedish transplant surgeons of that time – Sven-Eric Bergentz – I investigate how clinicians sought ways to solve the controversial problem of organ procurement. The institutionaliza
This study focuses on drivers for changing urban flood risk. We suggest a framework for guiding climate change adaptation action concerning flood risk and manageability in cities. The identified key drivers of changing flood hazard and vulnerability are used to provide an overview of each driver's impact on flood risk and manageability at the city level. We find that identified drivers for urban f
BACKGROUND: Previous studies have demonstrated an association between transplantation rate per center and postoperative mortality after heart transplantation. In 2011, Sweden centralized heart transplants and waiting lists, reducing the number of centers from 3 to 2. We aimed to assess the active waiting time and pre- and post-transplant mortality before and after centralization.METHODS: Heart tra
Recent studies of selective auditory attention have demonstrated that neural responses recorded with electroencephalogram (EEG) can be decoded to classify the attended talker in everyday multitalker cocktail-party environments. This is generally referred to as the auditory attention decoding (AAD) and could lead to a breakthrough for the next-generation of hearing aids (HAs) to have the ability to
Due to restrictions following the Covid-19 pandemic,major changes regarding teaching have been called for. Sincestudents’ presence in lab classrooms has been very restricted alsophysical labs have had to be transformed into e.g. simulationsperformed at home or via remote connections. After lifting of therestrictions, hybrid learning where both physical and simulatedlab environment are combined hav
The recently developed Phase-Scaled Reassignment (PSR) can estimate phase-difference between two oscillating transient signals with high accuracy. However, in low signal-to-noise ratios (SNRs) the performance of commonly applied reassignment techniques is known to deteriorate. In order to reduce variance in low SNR, we propose a multitaper PSR (mtPSR) method for phase-difference estimation between
Coherence is a useful measure in many engineering applications. Here, we focus on the case where the input signal to a linear system can be measured free from noise, but the output signal is perturbed by noise. A novel expression for the expectation of a multitaper magnitude squared coherence estimate for this case is presented and verified through numerical evaluation. Additionally, the expressio
In the literature, auditory attention is explored through neural speech tracking, primarily entailing modeling and analyzing electroencephalography (EEG) responses to natural speech via linear filtering. Our study takes a novel approach, introducing an enhanced coherence estimation technique to assess the strength of neural speech tracking. This enables effective discrimination between attended an
Time-frequency reassignment, commonly used to analyze time-varying signals, is a post-processing method that sharpens time-frequency representations. However, the reassignment method is sensitive to noise, making it unsuitable for time-frequency analysis when the signal-to-noise ratio is low. To increase the robustness of the reassignment technique, we develop a novel reassigned multitaper spectro
Introduction: Diabetic peripheral neuropathy (DPN) is a common complication of both type 1 (T1D) and type 2 diabetes (T2D). No cure for DPN is available, but several potential targets have been proposed for treatment. Heat shock proteins (HSPs) are known to respond to both hyper- and hypoglycemia. DPN can be diagnosed using electrophysiology and studied using peripheral nerve biopsies.Aim: This st
Background: In the strive towards a circular economy, metal waste recycling is a growing industry. During the recycling process, particulate matter containing toxic and allergenic metals will be emitted to the air causing unintentional exposure to humans and environment. Objective: In this study detailed characterization of particle emissions and workplace exposures were performed, covering the fu
Smart microscopy is transforming life sciences by automating experimental imaging workflows and enabling real-time adaptation based on feedback from images and other data streams. This shift increases throughput, improves reproducibility, and expands the functional capabilities of microscopes. However, the current landscape is highly fragmented. Academic researchers often develop custom solutions
Transient activation of fibroblasts into contractile myofibroblasts is essential for extracellular matrix (ECM) production and remodeling during wound healing and tissue regeneration. While ECM-dependent mechanisms mediating transient activation is well studied, how fibroblasts switch from transient to a persistently activated state and drive fibrosis and aberrant tissue repair in diseases such as
Group A Streptococcus (GAS) causes extensive global morbidity and rising rates of invasive disease, for which clinical outcomes remain poor despite antibiotic treatment of susceptible strains. This limitation of current therapy underscores the need for alternative or adjunctive approaches. Antibody-based interventions represent a promising but underexplored strategy. Historically, the streptococca
Metal oxide nanoparticles are widely used in catalysis, photovoltaics, and gas sensing, where surface structure and oxidation state strongly influence performance. This work investigates how carrier gas composition, combined with in-flight heating, can be used to control the surface properties of metal oxide nanoparticles generated via the gas-phase method, spark ablation. Sn, Zn, and Al nanoparti
Lipid nanoparticles (LNPs) are clinically approved for mRNA-based vaccines and liver-targeted siRNA delivery. However, poor nucleic acid delivery efficiency limits their application in extrahepatic tissues and tumors. Here, using live-cell and super-resolution microscopy, we identify multiple distinct steps of inefficiencies in the cytosolic delivery of both siRNA and mRNA cargoes. Membrane damage
Metal-assisted chemical etching (MACE) is a cheap and scalable method that is commonly used to obtain silicon nano- or microwires but lacks spatial control. Herein, we present a synthesis method for producing vertical and highly periodic silicon microwires, using displacement Talbot lithography before wet etching with MACE. The functionalized periodic silicon microwires show 65% higher PEC perform
