Supersonic combustion is a critical area of research for advancing high-speed flight technologies, particularly for the development of scramjet engines for hypersonic vehicles. This study employs Finite Rate Chemistry (FRC) Large Eddy Simulation (LES) together with different experimental techniques to study the supersonic flow and thermochemical processes in the Small Scale Flight Experiment (SSFE
IntroductionSlow sand filtration is an established method for drinking water treatment, however, the knowledge about their microbial ecology remains limited. Maintenance of slow sand filters (SSF) includes washing to remove biofilm growth in the sand and restore flow through the filter. Understanding how this impacts produced water is important as the SSF may influence the bacterial flora in the f
Abstract in FrenchDepuis longtemps, les anthropologues sont fascinés par les adaptations similaires et les différences intrigantes des cultures circumpolaires. Ces tendances ont été cartographiées, étudiées et interprétées sous différents angles, souvent à des niveaux sociaux ou spatiotemporels différents. Même si ces études ont produit d’importantes quantités de données, celles-cAnthropologists have long been fascinated by the strikingly similar adaptations of circumpolar cultures as well as their puzzling differences. These patterns of diversity have been mapped, studied, and interpreted from many perspectives and often at different social and spatiotemporal scales. While this work has generated vast archives of legacy data, it has also left behind a fragmented understan

In nature, bacteria usually exist as mixed-species biofilms, where they engage in a range of synergistic and antagonistic interactions that increase their resistance to environmental challenges. Biofilms are a major cause of persistent infections, and dispersal from initial foci can cause new infections at distal sites thus warranting further investigation. Studies of development and spatial inter
Disturbed haemostasis is a central finding in severe Streptococcus pyogenes infection. In particular, microthrombi are found both at the local site of infection and at distant sites. Platelets are responsible for maintaining vascular function and haemostasis. We report here that M1 protein of S. pyogenes triggers immune-mediated platelet activation and thrombus formation. M1 protein is released fr
In this paper, the authors show that liquid-liquid partition chromatography in an aqueous two-phase system offers unique possibilities of comparing the overall surface properties of intact antibodies in solution before and after binding of antigen. The authors demonstrate that the surface properties of antigen-antibody complexes are dependent on the variable regions of the antibodies, the nature o
Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-related mortality and can occur with any type of transfusion. TRALI is thought to be primarily mediated by donor antibodies activating recipient neutrophils resulting in pulmonary endothelial damage. Nonetheless, details regarding the interactions between donor antibodies and recipient factors are unknown. A murine a
Background and Purpose-We have previously shown that delivery of brain-derived neurotrophic factor (BDNF) through direct intrahippocampal gene transduction with a viral vector suppresses the formation of new dentate granule cells triggered by global forebrain ischemia. Here, we investigated whether inhibition of endogenous BDNF alters ischemia-induced neurogenesis in the dentate gyrus. Methods-Rat
In the current work, cationic polymers functionalized with N-alicyclic quaternary ammonium (QA) cations were synthesized and characterized as potential hydroxide exchange membranes (HEMs) for application in fuel cells. Three different polymers, namely poly(arylene ether sulfone), spiro-ionene and poly(arylene alkylene), were explored as polymer backbones for the HEMs. Various mono- and spirocyclic
In order to move away from fossil fuels many governments and industries are focusing their new investments in electricity and alternative fuels such as green hydrogen from electrolyzers using renewable electricity. High investment costs and electricity costs are a hindrance for the future development of a hydrogen economy which can utilize an increasing intermittent power generation. The aim of th
