Under electrochemical polarization, many electrocatalysts can undergo oxidation that alters their reactivity and can lead to restructuring and dissolution. In this context, the structure-property relationships of electrocatalysts, as well as their kinetics and dynamic behaviour, are still poorly understood. This knowledge gap mainly relies on the limitations of many traditional spectroscopic and s
We present results of Population III (Pop III) formation in the megatron suite of simulations, which self-consistently follows radiation and non-equilibrium chemistry, and resolves gas at near-pc resolution in a Milky Way-mass progenitor at Cosmic Dawn. While the very first Pop III stars form in haloes with masses well below the atomic cooling limit, the majority of Pop III stars form in more mass
Objectives: – To evaluate the prevalence of mood disorder symptoms and measure the quality of life in women with vulvar dermatoses attending a specialized vulvar clinic in southern Sweden. Materials and Methods: – A questionnaire-based study among consecutive women attending the vulvar unit at the Department of Dermatology and Venereology at Skåne University Hospital. Sociodemographic factors were
Background: The variable clinical outcomes of mesenchymal stromal cell (MSC)-based therapy in acute respiratory distress syndrome (ARDS) are attributed to a variety of factors, including host microenvironmental factors. Interleukin-1β (IL-1β) has been linked to the development and progression of ARDS, and we have previously found that IL-1β could be used to predict MSC activation in vitro. However
Standardized Care Pathway (SCP) for patients presenting with macroscopic haematuria was introduced in Sweden in 2015. In contrast to neighbouring countries, the Swedish model includes all patients with macroscopic haematuria above the age of 50, notwithstanding obvious causes. The aim of this study was to characterize the patients referred within the SCP and the presence of acute cystitis.All pati
Postural orthostatic tachycardia syndrome (POTS) as conventionally defined is a chronic condition (typically >3 months duration) incorporating reproducible symptoms of orthostatic intolerance (including dizziness/lightheadedness, and near-syncope) in the absence of orthostatic hypotension (i.e., absence of a sustained systolic blood pressure drop >20mmHg with upright posture). 1-10 More recently
Populärvetenskaplig sammanfattning: Naturbetesmarkerna minskade med 86,7% från 1927 till 1990. Denna minskning är alarmerande eftersom många idag hotade och sällsynta arter är beroende av dessa. En stor del av anledningen till detta är att staten ända in på 1980-talet i sin rådgivning danade för att dessa marker antingen skulle bearbetas med konstgödsel och ogräsbekämpning eller planteras med trädThe rural landscape of Sweden has changed rapidly during the 20:th century. Measurements from 1927 compared to those from 1990 show that the area of non managed pasture in Sweden has declined by 86.7 %. Since a lot of threatened and rare species are dependent of this kind of land, these figures are alarming. During the last 30-40 years non managed pasture has declined due to abandonment, tree plan
Populärvetenskaplig sammanfattning: Målet med studien är att se vilka samband som finns mellan insamlad fältdata och beräknad satellitdata för bokskogsbestånd i södra Sverige (Häckeberga naturreservat och naturområde). Fältdata som använts består av uppskattat bladyteindex, beräknad biomassa samt kategoriserade åldersgrupper av 19 provytor bokskog (Fagus Sylvatica), indelat i tre grupper. ProvytorThe aim of this investigation is to study the relationship between leaf area index, biomass and satellite reflectance data of some beech forests (Fagus Sylvatica) in southern Sweden (Häckeberga nature reserve). In 19 forest stands, measurements of tree structural parameters like tree height and tree diameter at breast height were performed. In addition, the leaf area index was estimated optically
Problem discussion: How should information be handled to facilitate and benefit from modularity? How should Clarkson Inc. adapt their information handling to modularity and what benefits can be reaped by doing this? Purpose: The purpose of this master thesis is to help Clarkson Inc. adapt their information handling to modularity and to extract theories, methods and tools to guide companies in simi
This study addresses the impact of witnessing different types of school bullying on Turkish school students who are bystanders. The primary aim is to investigate how the type of bullying (direct/indirect; ostracism/devaluation) affects the perception of bullying and the roles witnesses take. Additionally, we explore whether gender, global state self-esteem, and identification with one’s school acc
Background: Revascularization of a stenosis is warranted when hemodynamically significant. Coronary physiology provides a diagnostic tool for assessment of stenosis severity to aid in the decision to revascularize or defer. The iFR-SWEDEHEART trial demonstrated non-inferiority of the instantaneous wave-free ratio (iFR) compared to fractional flow reserve (FFR) in guiding decision-making in coronar
The rising prevalence of type 2 diabetes among migrant populations from low- and middle-income countries (LMICs) living in high-income countries (HICs) presents a significant public health challenge. Migrants often experience lifestyle changes, socioeconomic disadvantages and barriers to accessing healthcare, which can increase their risk for type 2 diabetes. This review explores the prevention an
Purpose: To achieve the high sensitivity of digital breast tomosynthesis (DBT), a time-consuming reading is necessary. However, synthetic mammography (SM) images, equivalent to digital mammography (DM), can be generated from DBT images. SM is faster to read and might be sufficient in many cases. We investigate using artificial intelligence (AI) to stratify examinations into reading of either SM or
As the global energy transition progresses, a range of drivers and barriers will continue to shape consumer attitudes and behavioural intentions towards emerging low-carbon technologies. The innovation-decision process for technologies composing the residential sector such as hydrogen-fuelled heating and cooking appliances is inherently governed by the complex interplay between perceptual, cogniti
Plurisexual people report worse mental health compared to heterosexual, lesbian, and gay people, but it is unclear how well-being compares between people with different plurisexual identities and demographic characteristics. We therefore conducted an online survey with 956 plurisexual individuals identifying as bisexual (n = 563), pansexual (n = 226) or bi- and pansexual (n = 194), measuring quali
In 2003, the Swedish Municipal Workers’ Union (Kommunal) called a nationwide strike, demanding a pay rise for all members in the public sector. Drawing on oral history interviews with workplace representatives and local union officials, the article examines how the struggle enabled changes in subjectivity, generating utopian visions for increased visibility and agency for municipal workers. This p
In Nordic countries, demand response (DR) programs are critical for enhancing energy flexibility and reducing peak electricity consumption in buildings and industry. Accurate short-term demand forecasting is essential to support these programs, especially in the context of cities with varying levels of data availability. This paper compares three different forecasting approaches for hourly electri
