As a promising carbon-free fuel, iron powder can directly combust with air and has great potential to provide clean and high-grad heat for various applications. The combustion characteristics of iron particles are of great significance for developing iron combustion model, designing efficient combustor, and optimizing combustion technologies. In this work, the micro-explosion behavior of burning i
Background: Adult children are often key carers of frail older parents providing care for a long period of time in different care contexts. However, research concerning adult children’s caregiving experiences, from providing home-based care to facing the death of a parent in a nursing home is sparse. Thus, the aim was to explore the transition from living at home to moving into and living in a nur
Background: Regenerex® is a porous titanium construct with a 3D interconnecting pore structure and biomechanical characteristics close to that of normal trabecular bone. This study aimed to compare the Regenerex (VR) to the non-interconnecting pore structure Porous Plasma Spray (VP) on tibial implants for total knee arthroplasty (TKA) at 5 years. Methods: We enrolled and randomized 61 patients (me
Economic growth is usually considered the main driver of convergence – the attainment by developing countries of income levels similar to those of industrialised nations. Although it has been recognised that achieving economic growth is not the same as sustaining it, analyses of the role of economic shrinking in the catching-up process, and how to build resilience to shrinking, are in short supply
Objective: Fatigue is one of the most prevalent and distressing symptoms reported by survivors of childhood cancer. There is currently a lack of longitudinal studies on cancer-related fatigue, and especially on the relationship between the course of fatigue during treatment and fatigue at follow-up. The purpose of the current study was therefore to investigate if the course of fatigue during treat
Background: Considering the adverse reactions to vaccination against coronavirus disease 2019 (COVID-19), some people, particularly the elderly and those with underlying medical conditions, are hesitant to be vaccinated. This study aimed to explore the prevalence of adverse reactions and provide direct evidence of vaccine safety, mainly for the elderly and people with underlying medical conditions
An accurate estimation of evapotranspiration (ET) is vital for understanding the global hydrological cycle. However, large uncertainties in the present global ET products originate from the distinct model structures, assumptions, and inputs. The maximum entropy production (MEP) model provides a novel method for modeling ET based on parsimonious inputs and energy conservation. In this study, an R p
BackgroundSurgical site infections (SSI) in the groin after vascular surgery are common. The aim of the study was to evaluate the effect of negative pressure wound therapy (NPWT) on SSI incidence when applied on closed inguinal incisions after endovascular aneurysm repair (EVAR).MethodsA multicenter randomized controlled trial (RCT). Between November 2013 and December 2020, 377 incisions (336 bila
Aims. Planets in the mass range from 2 to 15 M⊙ are very diverse. Some of them have low densities, while others are very dense. By measuring the masses and radii, the mean densities, structure, and composition of the planets are constrained. These parameters also give us important information about their formation and evolution, and about possible processes for atmospheric loss. Methods. We determ
BACKGROUND AND PURPOSE: The main radiological finding in progressive supranuclear palsy (PSP) is reduced midbrain volume. Both qualitative (e.g., hummingbird sign) and quantitative (e.g., area measurements) markers have been noted. Recent studies have shown a similar reduction also in idiopathic normal pressure hydrocephalus (iNPH). The purpose was to investigate the reliability and accuracy of th
Background: Despite reported tuberculosis (TB) treatment success rate of 86%, TB remains a leading cause of death in Ethiopia. We investigated patient and provider-specific factors associated with unfavorable treatment outcomes in Ethiopian health facilities providing TB care. Methods: Data on characteristics and treatment outcomes of patients registered for TB treatment at 15 public health facili
In Europe, individualist societies, in which people more highly value independence, have fewer people who are lonely. Yet these societies also have more people who live alone, a strong determinant of loneliness. Evidence suggests that some unrecognized societal-level resources or characteristics can explain this.We uncover multiple pathways toward a lower degree of loneliness among European societ
Introduction: The definition of asthma phenotypes has not been fully established, neither there are cluster studies showing homogeneous results to solidly establish clear phenotypes. The purpose of this study was to develop a classification algorithm based on unsupervised cluster analysis, identifying clusters that represent clinically relevant asthma phenotypes that may share asthma-related outco
Background: A comprehensive overview of neurologic complications among survivors of central nervous system (CNS) tumors in childhood is lacking. We aimed to investigate the risk for these disorders in a large, population-based study with outcome measures from nationwide hospital registries. Methods: We identified 4858 five-year survivors with diagnoses of CNS tumor in childhood in Denmark, Iceland
PURPOSE: Epilepsy is a common disabling condition, with high heritability according to twin studies. Characterization of familial risks for common subtypes of epilepsy will advance the search for the heritable causes of these conditions and their underlying mechanisms. We aim at defining familial risks for siblings to be hospitalized because of epilepsy.METHODS: A nationwide ad hoc epilepsy databa
Numerous migrant studies on cancer have been carried out, but little data are available on cancer incidence upon inter-European migration. We used the nationwide Swedish Family-Cancer Database to analyse cancer risk among Nordic immigrants and their offspring in Sweden. The parental population had entered Sweden in their 20s and they had become parents in Sweden. Finns were the largest immigrant g
Avian haemosporidians are vector-transmitted blood parasites that are distributed worldwide, abundant in many bird families and well studied across Europe and North America. Since avian haemosporidians have been poorly examined in the Palearctic migratory flyways of the Western Balkans, the goal of this study was to investigate which species of three haemosporidian genera, Plasmodium, Haemoproteus
