Lärares praktiska yrkeskunskaper bjuder motstånd mot förspråkligande. Detta problem föreligger inte minst i lärarutbildningen, där det i verksamhetsförlagda delar kan råda både osäkerhet och skilda uppfattningar om vad studenterna behöver göra eller prestera för att uppnå de mål som (bokstavligen) föreskrivits dem. Syftet med avhandlingen har varit att beskriva och förstå villkor och förutsättningTeachers' practical professional skills offer resistance to advocacy. This problem exists not least in teacher education, where in work-based parts there can be both uncertainty and different perceptions of what the students need to do or perform in order to achieve the goals that are (literally) prescribed for them. The purpose of the dissertation has been to describe and understand conditions an

Numerical simulations are performed to investigate the effects of ambient density (ρam) and nozzle diameter (Dnoz) on the ignition characteristic of diesel spray combustion under engine-like conditions. A total of nine cases which consist of different ρam of 14.8, 30.0, and 58.5 kg/m3 and different Dnoz of 100, 180, and 363 μm are considered. The results show that the predicted ignition delay time

Background: Endocrine-disrupting compounds (EDCs) are ubiquitous substances that are found in our everyday lives, including pesticides, plasticizers, pharmaceutical agents, personal care products, and also in food products and food packaging. Increasing epidemiological evidence suggest that EDCs may affect the development or progression of breast cancer and consequently lead to lifelong harmful he

Well before large-scale quantum computers will be available, traditional cryptosystems must be transitioned to post-quantum (PQ) secure schemes. The NIST PQC competition aims to standardize suitable cryptographic schemes. Candidates are evaluated not only on their formal security strengths, but are also judged based on the security with regard to resistance against side-channel attacks. Although r

Objectives We investigated gender differences in the association between mortality and general psychological distress (measured by 12-item General Health Questionnaire, GHQ-12), as an increased mortality risk has been shown in community studies, but gender differences are largely unknown. Setting We used data from a cross-sectional population-based public health survey conducted in 2008 in the Swe

Background: One of the preanalytical factors that can affect the results of arterial blood gas (ABG) analysis is the time from sample collection to analysis. A delay in analysis may affect the results due to factors such as ongoing cellular metabolism within the blood sample, gas exchange between the blood sample and the environment, and temperature changes. ABG analysis can be delayed for various

Phylogenies are central to many disciplines in biology. While disciplines such as systematics are focused on phylogenetic hypotheses themselves, other disciplines depend on robust and well-supported phylogenies in order to put biological data into evolutionary context through phylogenetic comparative studies. Examples of such fields are macroevolutionary research e.g. studying the evolution of a f

INTRODUCTION: Child stunting, a measure of malnutrition, is a major global health challenge affecting 148.1 million children in 2022. Global stunting rates have declined from 47.2% in 1985 to 22.3% in 2022; however, trends before the mid-1980s are unclear, including whether child stunting was previously prevalent in current high-income countries (HICs). We conducted a systematic review of child gr

Background: Explicit weight bias is known as negative attitudes and beliefs toward individuals due to their weight status and can be perpetuated through misconceptions about the causes of obesity. Individuals may also experience weight bias internalization (WBI) when they internalize negative weight-related attitudes and self-stigmatize. There is a paucity of research on the beliefs about the caus

This dissertation discusses mainly new cryptanalytical results related to issues of securely implementing the next generation of asymmetric cryptography, or Public-Key Cryptography (PKC).PKC, as it has been deployed until today, depends heavily on the integer factorization and the discrete logarithm problems.Unfortunately, it has been well-known since the mid-90s, that these mathematical problems

Motivation: The precise prediction of protein domains, which are the structural, functional and evolutionary units of proteins, has been a research focus in recent years. Although many methods have been presented for predicting protein domains and boundaries, the accuracy of predictions could be improved. Results: In this study we present a novel approach, DomHR, which is an accurate predictor of

Background: The development of entrustable professional activities (EPAs) as a framework for work-based training and assessment in undergraduate medical education has become popular. EPAs are defined as units of a professional activity requiring adequate knowledge, skills, and attitudes, with a recognized output of professional labor, independently executable within a time frame, observable and me

Aims/hypothesis: Regulatory factor X 6 (RFX6) is crucial for pancreatic endocrine development and differentiation. The RFX6 variant p.His293LeufsTer7 is significantly enriched in the Finnish population, with almost 1:250 individuals as a carrier. Importantly, the FinnGen study indicates a high predisposition for heterozygous carriers to develop type 2 and gestational diabetes. However, the precise

Background: Several factors and patient characteristics influence the risk of surgical wound dehiscence and incisional hernia after midline laparotomy. The purpose of this study was to investigate whether a specified, or not specified, suture quota in the operative report affects the incidence of surgical wound complications and to describe the previously known risk factors for these complications

Background and objective: Laboratories sometimes use different reference ranges for the same antiepileptic drug (AED), particularly for new and poorly investigated drugs. This may contribute to misunderstandings, concerns or inappropriate dose changes, which in turn may affect therapeutic effect, drug safety or treatment adherence. Therefore, the Norwegian Association of Clinical Pharmacology wish

IMPORTANCE: Over the past decades, many global regions have experienced a steady increase in the incidence of cutaneous melanoma. However, more recently, a downward trend has been observed in the younger age groups in Australia and the US. Yet, in Europe, none of the countries have reported any significant decline in melanoma incidence for any age group.OBJECTIVE: To assess melanoma incidence and

BACKGROUND: The efficacy and safety of minimally invasive distal pancreatectomy have been confirmed by randomized trials, but current patient selection and outcome of minimally invasive distal pancreatectomy in large international cohorts is unknown. This study aimed to compare the use and outcome of minimally invasive distal pancreatectomy in North America, the Netherlands, Germany, and Sweden.ME

BACKGROUND: The European registry for minimally invasive pancreatic surgery (E-MIPS) collects data on laparoscopic and robotic MIPS in low- and high-volume centers across Europe.METHODS: Analysis of the first year (2019) of the E-MIPS registry, including minimally invasive distal pancreatectomy (MIDP) and minimally invasive pancreatoduodenectomy (MIPD). Primary outcome was 90-day mortality.RESULTS

In this special session we wish to critique and reimagine the anthropocentric present. In contemporary consumerist society (Schmitt et al., 2022), the global “free market” is presented as the solution to the environmental and climate urgency through pillars like unlimited growth, responsibilized consumers, and not least, the domination of Nature (e.g. Hornborg 2019). There are alternatives, but thIn this special session we wish to critique and reimagine the anthropocentric present.

Chondroitin sulfate and keratan sulfate in guinea pig costal cartilage, nasal septum cartilage and nucleus pulposus were separated and fractionated by chromatography on CPC-cellulose, ECTEOLA-cellulose and Sephadex G-200 columns. Characterization of the chondroitin sulfates included determination of molecular weight and of the number, and position, of sulfate groups of the disaccharide units. Dist
