Lean premixed combustion (LPC) is a promising technology for low-NOx emission, while it increases the risk of blowoff at the same time. Experiments and Large Eddy Simulations (LES) on swirl stratified lean-premixed CH4/air flames were performed to study the differences between the stable and near blowoff flame. The flow fields and instantaneous flame structures were measured by simultaneous Partic

As a result of increasing bacterial resistance against antibiotics, we are facing an emerging health crisis, in which ‘simple’ infections may no longer be treatable. One class of molecules attracting interest in this context is antimicrobial peptides (AMPs), and considerable research efforts have been directed to identifying selective and potent AMPs. In addition, since in vivo delivery of AMPs is

Heat tolerance increases at higher acclimation temperatures in D. melanogaster, but not in D. subobscura. The two species represent separate lineages of the subgenus Sophophora of Drosophila with contrasting tropical African and temperate Palearctic evolutionary histories. D. melanogaster has five copies of the inducible hsp70 gene distributed in two clusters, named A (with two copies) and B (thre

Following the 7.5-Mw earthquake that occurred on 28 September 2018, a series of field surveys were performed to further understand the impacts of the resulting tsunami. Tsunamis initiated by strike-slip earthquakes are rare. Other factors are suspected to have contributed to this unusual tsunami. One of these factors was the subaerial landslides around Palu Bay, which were observed at several loca

Adequate reliability of measurement is a precondition for investigating individual differences and age-related changes in brain structure. One approach to improve reliability is to identify and control for variables that are predictive of within-person variance. To this end, we applied both classical statistical methods and machine-learning-inspired approaches to structural magnetic resonance imag

A total of 16 global chemistry transport models and general circulation models have participated in this study; 14 models have been evaluated with regard to their ability to reproduce the near-surface observed number concentration of aerosol particles and cloud condensation nuclei (CCN), as well as derived cloud droplet number concentration (CDNC). Model results for the period 2011-2015 are compar

Background: Neuropathological studies have linked tau aggregates to neuronal loss. To describe the spatial distribution of neurofibrillary tangle pathology in post-mortem tissue, Braak staging has been used. The aim of this study was to examine in vivo associations between tau pathology, quantified with [18F]flortaucipir PET in regions corresponding to Braak stages, and atrophy across the Alzheime

Background: Infarct evolution rate and response to acute reperfusion therapy may differ between patients, which is important to consider for accurate management and treatment of patients with ST-elevation myocardial infarction (STEMI). The aim of this study was therefore to investigate the association of infarct size and myocardial salvage with gender, smoking status, presence of diabetes or histo

Background: In 2006 and 2007 we performed double lung transplantation with marginal donor lungs assessed and reconditioned by Ex Vivo Lung Perfusion (EVLP), using a technique developed by Professor Stig Steen. Here we present a 10-year follow-up comparing the outcomes of lung transplantations performed at our clinic using EVLP lungs vs. conventional lungs. Method: Between 2006 and 2007, 21 patient

Objectives. To examine faecal calprotectin (F-calprotectin) levels and presence of anti-Saccharomyces cerevisiae antibodies (ASCA) and their associations with disease subtype and current status in axial SpA (axSpA). Methods. F-calprotectin and ASCA in serum were compared between consecutive patients with a clinical axSpA diagnosis, classified as non-radiographic axSpA (nr-axSpA; n = 40) or AS (n =

Behavioral adaptations play an important role in predator–prey interactions as they reduce predation risk. Prey organisms have therefore evolved a tremendous variability in behavioral adaptations. In case of small crustaceans of the genus Daphnia, which are common and important herbivores transferring energy from primary producers to higher trophic levels, such as predatory fish, and insects, alte

The main objective for this article is to explore how users of psychoactive drugs experience time and the role psychoactive drugs play in the management and construction of time. The data in this study consists of different kinds of written documents such as anecdotal accounts and scientific articles and reports which was collected using a purposeful sampling technique.

AIMS: This nationwide study aimed to analyse the first 2 years of routine clinical use of cangrelor in all Swedish patients undergoing percutaneous coronary intervention (PCI). METHODS AND RESULTS: This observational Swedish Coronary Angiography and Angioplasty Registry (SCAAR) study identified 915 cangrelor-treated patients. As 899 were ST-segment elevation myocardial infarction (STEMI)-patients

We investigate the relation between large negative house price co-movements in the cross-section of US cities and the national business cycle. The occurrences of large negative house price co-movements across cities cluster over time and these clusters are closely linked to NBER recession dates. A simple co-movement measure that aggregates large negative city-level house price returns reliably pre

Electron density determination based on structure factors obtained through powder X-ray diffraction has so far been limited to high-symmetry inorganic solids. This limit is challenged by determining high-quality structure factors for crystalline urea using a bespoke vacuum diffractometer with imaging plates. This allows the collection of data of sufficient quality to model the electron density of
