Healthcare Professionals' Perceptions of Pre-, Peri-, and Postoperative Virtual Reality Immersion in Elderly Patients

Background/Objectives: There is a lack of research examining healthcare professionals' perspectives regarding the potential of non-pharmacological solutions such as immersive virtual reality (VR). The aim of this study was to investigate opportunities and challenges related to the application of immersive virtual reality (VR) technology in patients aged 65 and older undergoing surgery with regiona

Status of Sepsis Care in European Hospitals Results from an International Cross-Sectional Survey

Rationale: Early detection, standardized therapy, adequate infrastructure, and strategies for quality improvement should constitute essential components of every hospital’s sepsis plan. Objectives: To investigate the extent to which recommendations from the sepsis guidelines are implemented and the availability of infrastructure for the care of patients with sepsis in acute-care hospitals. Methods

The effects of virtual reality (VR) on clinical skills training in undergraduate radiography education : A systematic review

INTRODUCTION: The primary objective was to map the impact on confidence and performance on radiographic examinations among undergraduate radiography students utilizing virtual reality (VR). The secondary objective was to identify potential pitfalls to avoid in future VR implementation.METHODS: A systematic review was conducted, which included comprehensive search in nine databases. The software Co

Close Stellar Encounters: Investigating the Distribution of Minimum Distances of Sun-Star and Star-Star Approaches

Av de tusentals stjärnor som analyserats i detta arbete framträder stjärnan Gliese 710 som särskilt intressant. Denna stjärna förväntas passera solen på ett avstånd av ungefär 10000 gånger avståndet mellan jorden och solen, om cirka 1.3 miljoner år. Även om detta låter avlägset kan en sådan förbiflygning störa det avlägsna Oort-molnet som omger solsystemet, vilket potentiellt kan öka antalet kometClose stellar encounters play a critical role in shaping planetary systems by perturbing the orbits of minor body populations like the Oort Cloud and the orbits of planets. Using data from the Gaia DR3 catalogue, this work quantifies close stellar encounters, investigating both Sun-star and star-star interactions. Assuming that stars move in straight lines, encounter distances and times were com

Resilience of offshore renewable energy systems to extreme metocean conditions : A review

The replacement of fossil fuels by intermittent renewable energy sources is transforming energy systems world-wide. A significant part of the future electricity demand will be supplied by offshore renewable energy, especially wind, but emerging technologies such as wave and tidal energy also offer great potential. However, the ability of offshore renewable energy systems – and of power systems and

RoadRAT – A new framework to assess the probability of inundation, wave runup, and erosion impacting coastal roads

This paper introduces a new framework – RoadRAT - to calculate the probability of inundation, wave runup, and storm erosion impacting coastal roads. Extreme value analysis is applied to annual maxima of observed and simulated still water level levels (SWL), total water levels (SWL + runup), and storm erosion volumes. The probability of impact on the road is derived both for the present conditions

Exploring consumer perception of uncoated wooden cladding : A study across three European countries

With increased focus on sustainable building materials and the growing popularity of uncoated wooden cladding, understanding consumer acceptance of aesthetic changes becomes crucial for sustainable architectural choices. This study investigated consumer acceptance of uncoated wooden cladding in Norway, Sweden, and Germany, focusing on personality traits and perceptions. Using an online survey with

No title

In this article I first follow Aristotle's and Plato's critique of materialism in an ancient context, then, in order to bring the topic into a more modern discussion, I follow Marx' dissertation on Democritos and Epicurus in its attempts to counter this critique from a materialist standpoint. Finally I conclude in reaffirming and nuancing Aristotle's critique, showing the limits of using matter as

En minut hit eller dit : Fördjupad förståelse av restidens betydelse i kollektivtrafiken

Denna studie undersöker hur restid upplevs och används av kollektivtrafikresenärer. Genom en enkät med drygt tusen respondenter och samtal i en fokusgrupp framkommer flera intressanta insikter.Mobiltelefonen har blivit den mest använda utrustningen ombord, medan traditionella medier som böcker och tidningar har minskat i förekomst. Vanliga aktiviteter under resan inkluderar att scrolla på mobilen,This study examines how travel time is perceived and utilised by public transport passengers. Through a survey of just over a thousand respondents and discussions in a focus group, several interesting insights emerge.The mobile phone has become the most used device on board, while traditional media such as books and newspapers have decreased in prevalence. Common activities during the journey incl

The impact of political attention on collaborative environmental governance among municipal street-level bureaucrats

Collaboration in governing complex environmental challenges is the norm. However, collaboration does not necessarily deliver desirable outcomes, and the importance of forming collaborative networks that effectively address the challenges at hand has been emphasized in theory and practice. Evidence for what constitutes a suitable network structure is still scarce, and the understanding of what fact

Developing sufficiency-based sharing principles for absolute environmental sustainability assessment using decent living standards and planetary boundaries

Absolute environmental sustainability assessments quantify the environmental impacts of human activities in relation to ecological carrying capacities. Such assessments necessitate the application of sharing principles to allocate shares of carrying capacity to actors and activities at different scales, including products, companies, sectors, and countries. This can help decision-makers set target

Field-hybridization acoustic tweezers

Precise control of individual particles is crucial for biomedical diagnostics, i.e., single-cell analysis and drug delivery. Acoustic tweezers have shown promise as a precise method for capturing microscale objects, but the spatial selectivity remains challenging to achieve with traditional electroacoustic transducers. An alternative to traditional ultrasound generation is to use photoacoustic con

Estimating erosion resistance of vegetated sea dike embankments through in situ experiments

Through in situ experiments, this study investigated the erosion resistance of a prototype dike with different vegetation and soil sections built on the Falsterbo peninsula, Sweden. A gravity-driven wave impact simulator was used to simulate waves breaking on the dike. Two sandy soils and three vegetation types (standard grass, biodiverse seed mixture, and hay) were tested for this study. In gener

In Situ Detection of Programmed Cell Death Protein 1 and Programmed Death Ligand 1 Interactions as a Functional Predictor for Response to Immune Checkpoint Inhibition in NSCLC

Introduction: Immune checkpoint inhibitors (ICIs) have transformed lung cancer treatment, yet their effectiveness seem restricted to certain patient subsets. Current clinical stratification on the basis of programmed death ligand 1 (PD-L1) expression offers limited predictive value. Given the mechanism of action, directly detecting spatial programmed cell death protein 1 (PD1)–PD-L1 interactions m

Synthetic transitions : The political economy of fossil fuel as feedstock

With simultaneous policy and scholarly attention to the pollution crisis and the climate crisis, there is growing recognition that the two are intimately interconnected through the demand for oil, gas, and coal generated by synthetic materials. Drawing on theoretical resources from international political economy and beyond, we show how petrochemicals sit at the intersection of a number of the pri

A Hybrid Cuk PFC Converter for 48 V – 12 Ah Battery Charging Application

Power Factor Correction (PFC) converters are essential in designing any charging architecture, regardless of the battery's capacity and the application. Nevertheless, power converters, having continuous output current features, are widely used for battery charging applications. In contrast, converters with continuous input current characteristics exhibit better PFC performance. The Cuk converter c
