Monitoring health of a power system

Utilizing green hydrogen produced by water electrolysis offers a viable strategy to mitigate the global energy crisis. In the present work, a high-performance, readily synthesized, and cost-effective anion exchange membrane (AEM) for alkaline water electrolyzers has been developed and studied. Glycidyl trimethyl ammonium chloride (GTA) was grafted onto poly(oxindole biphenylene) (POB) through

Objectives: To report the long-term outcomes from a longitudinal psychosocial study that forms part of the ‘Identification of Men with a genetic predisposition to ProstAte Cancer: Targeted Screening in men at higher genetic risk and controls’ (IMPACT) study. The IMPACT study is a multi-national study of targeted prostate cancer (PrCa) screening in individuals with a known germline pathogenic varia

Genome-wide association studies (GWASs) based on common single nucleotide polymorphisms (SNPs) have identified several loci associated with the risk of monoclonal gammopathy of unknown significance (MGUS), a precursor condition for multiple myeloma (MM). We hypothesized that analyzing haplotypes might be more useful than analyzing individual SNPs, as it could identify functional chromosomal units

Students’ learning developments of limits were studied in a calculus course. Theiractions, such as problem solving and reasoning, were considered traces of theirmental representations of concepts and were used to describe the developmentsduring a semester. Several students went through the course with a vague conception of limits which in some cases was wrong. A higher awareness about their mental

Most concepts taught in a basic analysis course at university are somewhatfamiliar to the students. They use their representations from prior experiences toform new knowledge about the concepts. Fifteen students’ were examined at thebeginning of a basic university course in analysis. Their pre-knowledge wassometimes vague and even wrong, often due to intuitive perceptions.

The paper presents a work in progress which is part of a larger study. Studentslearning analysis was investigated with the aim to find out how their concept images changed from the beginning of an analysis course to a year after the course. Their links between concepts were studied after the year had passed. The influence of the students’ pre-knowledge was durable and sometimes prevented students

A group of pre-service teachers were studied from two social practices, as teachers and as students. Their perceptions of mathematics concepts and beliefs about the mathematics teacher role were studied through questionnaires, interviews and classroom observations. Three students were selected as cases in this paper where their links between the concepts limits, derivatives, integrals and continui

The aim of this three-year study is to further contribute to the understanding of how relations between Reality – Theoretical models – Mathematics are communicated in Swedish upper-secondary physics. A developed analytical framework (Hansson, Hansson, Juter, & Redfors, 2015; 2019) is used to focus the analysis of the classroom communication on relations made (by teachers and students) between

Agricultural intensification is widely recognised as a primary driver of pollinator loss, but the success of land-management actions designed to remediate its impact is often mixed. Payments to farmers to increase habitat connectivity or the availability of floral and nesting resources may only result in short-term gains or even unintended consequences. The reasons may lie in changes to interactio

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

To examine whether the level of genetic risk in psychiatric disorders impacts the social functioning of affected individuals, we examine the relationship between genetic risk factors for major depression (MD), anxiety disorders (AD), bipolar disorder (BD), non-affective psychosis (NAP), alcohol use disorder (AUD), and drug use disorder (DUD) in disordered individuals and five adverse social outcom
