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
This CMES Regional Outlook by Pinar Dinc focuses on the recent political developments in Turkey.
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
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
Purpose: The aim of this study was to evaluate risk factors for postoperative pain and nausea after open repair for primary ventral hernias. Method: A population-based registry study was conducted based on data assembled from the Swedish national ventral hernia repair register between January 2016 and December 2021and cross-matched with the Swedish perioperative register. Results: Altogether 2064
Women have always played a central role in smallholder agriculture in many farming systems of the Global South. However, they have had, and still have, low access to agricultural information, and even less ability to enact on training or advice received, in comparison to male farmers. The paper investigates what is needed for female smallholders to better benefit from agricultural advice and train
A crystallogenesis study of human transthyretin using the counter-diffusion method is described as an alternative to conventional convective vapour diffusion and batch approaches for protein crystallization. The X-ray diffraction results show systematic trends that exhibit unique patterns of crystallization and high crystal quality as well as a remarkable degree of coherence within extended crysta
INTRODUCTION: Behavioral and psychological symptoms of dementia (BPSD) are a common driver of suffering and high care needs. We describe the Swedish BPSD registry, founded in 2010 to develop an evidence base for quality improvement in the care of patients with BPSD. Further, we illustrate the potential of the registry by evaluating how individual BPSD affects mortality. METHODS: The registry provi
In several circumstances, a level-three automated vehicle cannot continue driving in an automated driving mode and requests a human driver to take over. In this study, a series of experiments to examine how to provide a TOR was conducted. First, for forty-one persons, a HUD icon, earcon, seat vibration, and combinations were compared. The results indicated that the HUD icon-earcon and HUD icon-sea
Melanin pigments play a critical role in physiological processes and shaping animal behaviour. Fossil melanin is a unique resource for understanding the functional evolution of melanin but the impact of fossilisation on molecular signatures for eumelanin and, especially, phaeomelanin is not fully understood. Here we present a model for the chemical taphonomy of fossil eumelanin and phaeomelanin ba
The respiratory tract deposited fraction (DF) is the link between exposure and health effects of airborne particles. Here, we investigate how breathing pattern alterations at increasing physical activity affect DF in different regions of the respiratory tract and compare DF between adults and children (5 and 10 years old). We performed a literature review on the alteration of tidal volume with min
In global cities, the impacts of gentrification on the lives and well-being of socially vulnerable residents have occupied political agendas. Yet to date, research on how gentrification affects a multiplicity of health outcomes has remained scarce. While much of the nascent quantitative research helps to identify associations between gentrification and determined health outcomes, it tends to draw
Municipal climate resiliency and re-naturing plans are promoting greening and green (re)development, such as the inclusion of new parks, greenways, or rehabilitated shorelines, frequently as a-political, win-win solutions for all residents. Greenwashing and (re)development of green amenities in vulnerable neighborhoods—those often most in need of support toward resilience and adaptation—expose res
The purpose of the study was to develop a simple and rapid method for measuring the average settling velocity of particles in stormwater ponds. Water samples with suspended particles were collected from the bottom of a stormwater pond in Lund, Sweden. The absorbance in various samples was measured over 24 hours (at 600 nm wavelength) and then translated into total solids concentrations. A one-dime
Research on personality traits predicting life outcomes has typically been investigated using the Big Five factors and only occasionally their facets. However, recent research suggests that the use of items (reflecting personality nuances) can account for more predictive variance. The aim of the present study was to examine the predictive validity for various life outcomes comparing the hierarchic
This article introduces a novel testing system for investigating rock hydromechanical behavior with neutron and X-ray imaging techniques. The system comprises four subsystems: an axial compression system, a confining pressure system, a fluid flow system, and a triaxial cell. In order to enable imaging with both modalities to track fluid flow and deformation in situ and 3D, the cell was designed to
