In pursuit of advancing the capabilities of ground testing facilities, a complete road map for broadening operational range of the H3 hypersonic blowdown wind tunnel, operated at the von Karman Institute for Fluid Dynamics (VKI), with the addition of a new Mach 5 contoured nozzle is constructed. The main characteristics of the facility are presented. The supersonic ejector is identified as a criti
Future climate scenarios are predicting considerable threats to sustainable maize production in arid and semi-arid regions. These adverse impacts can be minimized by adopting modern agricultural tools to assess and develop successful adaptation practices. A multi-model approach (climate and crop) was used to assess the impacts and uncertainties of climate change on maize crop. An extensive field s
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
This CMES Regional Outlook by Pinar Dinc focuses on the recent political developments in Turkey.
Due to the large amount of accidents negatively affecting the wellbeing of the survivors and their families, a substantial amount of research is conducted to determine the causes of road accidents. This type of data come in the form of non-negative integers and may be modelled using the Poisson regression model. Unfortunately, the commonly used maximum likelihood estimator is unstable when the exp
Contemporary research observes how foreign information influence present a governing challenge for liberal democratic states. Less attention has been paid to how this governing dilemma emerged in its present form. This article outlines a genealogy of the longstanding Swedish strategy of psychological defence with the aim of tracing historical trajectories of liberal democratic thinking about infor
Postgraduate education has been recognised as a key to bring about societal change. While further capacity building is imperative in this regard in East Africa (Wao et al., 2022), we will in this study focus on how supervisors function as important role models to their students (Brodin et al., 2020). We assume that supervisors’ own approaches to societal change affect their supervisor relationship
In recent years, a growing interest in sustainable tourism and outdoor recreation has emerged in Sweden and globally. While a positive development for many reasons, it coincides with other shifting patterns in recreational nature use, influenced by climate change, social media, and experimental interventions in natural areas. These developments bring opportunities to broaden participation, but als
Background and objective: Guideline recommendations regarding early management of grade group (GG) 2 prostate cancer with confirmatory biopsy (cBx) are not well established. Our aim was to determine which patients with GG 2 cancer should undergo cBx before treatment decision-making by evaluating the probability of downgrading to GG 1 or no cancer on cBx. Methods: This was a single-institution retr
Atrial fibrillation and heart failure have both been suggested to increase stroke and dementia risk. However, in observational studies, reversed causation and unmeasured confounding may occur. To mitigate these issues, this study aims to investigate if higher genetic risk for atrial fibrillation and heart failure increases dementia and stroke risk. Data were obtained from the population-based Goth
Introduction: The pulmonary oxygen uptake is reduced during apnea, compared to eupneic baseline, preserving the pulmonary oxygen store. This study elucidates the time course for this reduction, comparing it to the time course for apnea-induced cardiovascular responses. Methods and results: Experiments involved two groups, performing apneas during rest, both without and with cold-water face immersi
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
To evaluate an atomic force microscopy (AFM) approach for effective density analysis of single spray dried carbohydrate particles in order to investigate the internal structure of the particles. In addition, the AFM method was compared to an established technique, that is gas pycnometry. Resonant frequency AFM analysis was employed for determination of the mass of individual particles of spray-dri
Debate over the future of international science takes place in light of two trends that are frequently interpreted as standing in tension with each other. The longer-term pattern shows that science is increasingly an international endeavour, as collaboration across borders has grown. A more recent apparent re-nationalisation of science, however, raises questions over the march of international sci
INTRODUCTION: Esophageal squamous cell carcinoma (ESCC) carries a poor prognosis, but earlier tumor detection would improve survival. We aimed to develop and externally validate a risk prediction model based on exposure to readily available risk factors to identify high-risk individuals of ESCC.METHODS: Competing risk regression modeling was used to develop a risk prediction model. Individuals' ab
OBJECTIVE: Cone beam computed tomography (CBCT) can accurately assess erosive disease in the hands, wrists and feet in established rheumatoid arthritis (RA). The aim of this study was to compare CBCT with conventional radiography (CR) for the assessment of erosions in patients with early RA.METHODS: CBCT and CR of the hands, wrists and feet of 17 patients with treatment naive early RA were assesse
BACKGROUND: Attention Deficit Hyperactivity Disorder (ADHD) is a commonly occurring neurodevelopmental disorder associated with impairments in numerous aspects of functioning and quality of life. There is a growing recognition that brief and effective psychosocial interventions are needed for youth with ADHD.OBJECTIVE: The aim of this study was to assess the feasibility and preliminary effectivene
BackgroundComorbidity burden may affect the outcome following endovascular thrombectomy (EVT) for medium‐vessel occlusions. Since patients with high comorbidity burden are likely to be underrepresented in trials on EVT for medium‐vessel occlusions, observational data are needed to assess the benefit of EVT for these patients.MethodsWe conducted an observational study on all prestroke independent p
