AC-DC converters are mostly used as power supplies for microelectronic systems, battery chargers, wind energy applications, electric appliances in household and dc motor drives. Switched-capacitor (SC) network based converters can be good solution to the challenges of 21st century having high voltage conversion ratio and low EMI emissions. The application of this type of converters is in microproc
The nasal mucosa is the first immunologically active site that respiratory viruses encounter and establishing immunity at the initial point of pathogen contact is essential for preventing viral spread. Influenza A virus (IAV) in humans preferentially replicates in the upper respiratory tract (URT) but mouse models of infection result in lower respiratory tract infection. Here, we optimize IAV inoc

Ledelse er et af de mest omtalte og undersøgte fænomener i moderne organisationer. Det bliver ofte fremhævet som nøglen til succes. Men er ledelse virkelig den universelle løsning på alle organisatoriske udfordringer, og hvordan udfolder det sig i praksis, når ledere forsøger at omsætte ambitioner til handling? Denne bog går bag om de velkendte fortællinger og præsenterer et mere nuanceret billede
OBJECTIVE: To explore the associations between daily time in sedentary behaviour (SED) and physical activity (PA) with perceived physical capacity, health-related quality of life (HRQoL) and fatigue in persons with post COVID-19 condition (PCC). An additional objective was to describe changes in SED and PA levels over three months.MATERIALS AND METHODS: Individuals with PCC self-reported on physic
AIMS: To investigate whether out-of-hospital cardiac arrest (OHCA) survivors had lower levels of self-reported physical activity compared to a non-cardiac arrest control group with myocardial infarction (MI), and to explore if symptoms of anxiety, depression, kinesiophobia (fear of movement) and fatigue were associated with a low level of physical activity.METHODS: Predefined case-control sub-studAIMS: To investigate whether out-of-hospital cardiac arrest (OHCA) survivors had lower levels of self-reported physical activity compared to a non-cardiac arrest control group with myocardial infarction (MI), and to explore if symptoms of anxiety, depression, kinesiophobia (fear of movement) and fatigue were associated with a low level of physical activity.METHODS: Predefined case-control sub-stud
Marine environments worldwide are increasingly threatened by warming, deoxygenation, and ocean acidification. These stressors can be recorded as alterations in foraminiferal geochemistry and morphology. We integrated morphological features with assemblage and geochemical records of benthic foraminifera from the Danish Straits at the entrance to the Baltic Sea, covering the Last Interglacial period
Introduction: Homecare services are limited, and there is likely a gap between the everyday activities homecare users want to do and the activities they perform or receive help with. Structured assessment on the desire for engaging in activities may be useful to identify unmet occupational needs.Aim: To reflect on the experiences of using the Occupational Gaps Questionnaire (OGQ) to investigate ho
The global energy transition is not merely a technological shift toward renewable energy but also a transformation of power structures, agency, and governance. As nations and cities implement sustainable energy solutions, both traditional energy actors and new entrants are reshaping participation in the energy sector. Within this evolving context, the smart grid emerges as an arena where these dyn
Pulmonary arterial hypertension is a complex and heterogeneous condition, associated with a considerable diagnostic delay, diminished exercise capacity, and poor outcomes. In pulmonary arterial hypertension, biomarker research has become a subject of intense inquiry, and novel circulating biomarkers acknowledged in a multitude of mechanistic pathways are emerging. Beyond the widely used natriureti
BackgroundInflammation and tyrosine-kinases are known mediators in the pathobiology of cardiovascular disease. Plasma biomarkers reflecting these systems may provide a noninvasive complement reflecting hemodynamics, aiding in clinical decision-making. We therefore aimed to investigate the plasma levels of vascular and inflammatory proteins, and their associations with invasive hemodynamics in adva
The purpose of this study is to look into patronage effects of extended supply outside peak hours on regional public transport services. Previous studies have shown that the service frequency is an attribute of great importance for regional passengers, but little is known about the details regarding peak and off-peak frequencies or service hours. The present study addresses this knowledge gap, dep
Based on fieldwork in a sensory science laboratory in Sweden, this paper brings the social aspects of conducting an analytical sensory panel together with consumers’ understandings of the everyday consumption context and existing practices. As part of an interdisciplinary project investigating seaweed as a new food in a Swedish context, this paper explores how seaweed as a new resource is made edi
The global shift to a knowledge-based economy is driven by rapid advancements in information and communication technology (ICT). Within this landscape, digital transformation of supply chains is crucial for enterprises, particularly small and medium-sized businesses (SMEs), seeking to boost performance and efficiency in competitive markets. Despite increased awareness of this importance, there is
The surging demand for Intelligent Transportation Systems (ITS) to deliver advanced train-related Information for dispatchers and passengers has spurred the development of advanced train delay prediction models. Despite considerable efforts devoted to developing methodologies that can be used to model train operation conditions and produce anticipated train delays, the evaluation strategies for tr
This study reports contact pressure-sliding speed maps for friction, wear and particle emissions from high-speed train brakes. Two particle spectrometers measured the airborne wear particles generated with a pin-on-disc tribometer. Particles were characterized with transmission electron microscopy and energy dispersive X-ray fluorescence. The results indicate that both the friction and wear of bra
