Large-Eddy Simulation of Supersonic Combustion in a Mach 2 Cavity Model Scramjet Combustor

In this study, we report on reactive large-eddy simulations (LESs) of flow and combustion in the U.S. Air Force Research Laboratory Research Cell 19 cavity-based scramjet combustor. This case involves the combustion of ethylene that is injected into a cavity. It has previously been studied experimentally with multiple techniques, including particle image velocimetry, hyperspectral imagining, and l

α-Synuclein interaction with POPC/POPS vesicles

We have investigated the adsorption of the amyloid-forming protein a-Synuclein (aSyn) onto small unilamellar vesicles composed of a mixture of zwitterionic POPC and anionic POPS lipids. aSyn monomers adsorb onto the anionic lipid vesicles where they adopt an a-helical secondary structure. The degree of adsorption depends on the fraction of anionic lipid in the mixed lipid membrane, but one needs t

Data of the Insect Biome Atlas : a metabarcoding survey of the terrestrial arthropods of Sweden and Madagascar

We present the data from the Insect Biome Atlas project (IBA), characterizing the terrestrial arthropod faunas of Sweden and Madagascar. Over 12 months, Malaise trap samples were collected weekly (biweekly or monthly in the winter, when feasible) at 203 locations within 100 sites in Sweden and weekly at 50 locations within 33 sites in Madagascar; this was complemented by soil and litter samples fr

Drug-coated balloons versus drug-eluting stents for small non-complex de novo coronary artery lesions : A segment-level propensity score matched analysis from SCAAR

BACKGROUND: The REC-CAGEFREE trial showed that drug-coated balloons (DCB) did not achieve non-inferiority in the treatment of non-complex de novo lesion compared to a strategy of drug-eluting stents (DES). However, a prespecified subgroup analysis of arteries sized <3.0 mm revealed no difference in the device-oriented outcome compared to DES. The aim of present study was to validate that finding i

Cord clamping beyond 3 minutes : Neonatal short-term outcomes and maternal postpartum hemorrhage

BACKGROUND: Delaying cord clamping (CC) for 3-5 minutes reduces iron deficiency and improves neurodevelopment. Data on the effects of CC beyond 3 minutes in relation to short-term neonatal outcomes and maternal risk of postpartum hemorrhage are scarce.METHODS: This was a prospective observational study performed in two delivery departments. Pregnant women with vaginal deliveries were included. Tim

Making the Argument for Intact Cord Resuscitation : A Case Report and Discussion

We use a case of intact cord resuscitation to argue for the beneficial effects of an enhanced blood volume from placental transfusion for newborns needing resuscitation. We propose that intact cord resuscitation supports the process of physiologic neonatal transition, especially for many of those newborns appearing moribund. Transfer of the residual blood in the placenta provides the neonate with

Risk-based multi-criteria decision analysis method for considering the effects of climate change on bridges

Recent studies have identified many potential climate change impacts on bridges. Considering the sheer number of these potential impacts, how can a bridge owner prioritise which impacts to consider, and for which bridges? This paper proposes a risk-based multi-criteria decision analysis method for systematically addressing these two questions simultaneously. The proposed method can be used to addr

SRIQ clustering : A fusion of Random Forest, QT clustering, and KNN concepts

Gene expression profiling together with unsupervised analysis methods, typically clustering methods, has been used extensively in cancer research to unravel, e.g., new molecular subtypes that hold promise of disease refinement that may ultimately benefit patients. However, many of the commonly used methods require a prespecified number of clusters to extract and frequently require some type of fea

Three Learning Organizations in Cataract Surgery : The Example of Intracameral Antibiotic Injection

BACKGROUND: The recent systematic adoption of intracameral antibiotic injection during cataract surgery in Sweden, India, and the US serves as a model for the successful transitioning of local quality improvement initiatives to organization-wide implementation. Although the delivery of eye care in the 3 countries is distinctly organized with differing governances and technological infrastructure,

The role of detectability in the evolution of avian-dispersed fruit color

If the primary function of avian-dispersed fruit coloration were the maximization of detectability, then the commonest avian-dispersed fruit colors should be the ones most detectable to birds. We tested this prediction by photographing 63 fruit species primarily dispersed by birds, in situ in Sweden and Australia, with a multispectral camera closely mimicking the predominant spectral sensitivities

Cold exposure increases cyclic guanosine monophosphate in healthy women but not in women with Raynaud's phenomenon

OBJECTIVE: To investigate influence of whole-body cooling on cyclic GMP (cGMP) in women with Raynaud's phenomenon and in healthy women.DESIGN: The study was performed as an open, parallel-group comparison between women with Raynaud's phenomenon and healthy women during the winter month of February.SETTING: The municipality of Västerås (Sweden).PARTICIPANTS: The Raynaud group comprised 24 female pa

Effects of pre-injection on ignition, combustion and emissions of spray under engine-like conditions

Large-eddy simulation (LES) of multiple-injection spray combustion under engine-like conditions is performed using a coupled model of an Eulerian stochastic field transported probability density function (ESF T-PDF) and a flamelet generated manifold (FGM). This coupled model allows the use of the T-PDF methods in modeling the interaction of turbulence and chemistry at affordable computational cost

Plasma nitric oxide metabolite in women with primary Raynaud's phenomenon and in healthy subjects

Primary Raynaud's phenomenon (PRP) is characterized by cold- or stress-induced transient attacks of impaired skin circulation in fingers and/or toes. PRP displays seasonal variation with less severe symptoms in the summer. The aetiology has not been clarified. The aims of the present study were (a) to assess the influence of cold exposure on the plasma levels of the nitric oxide (NO) metabolite, n

Seasonal variations in cyclic GMP response on whole-body cooling in women with primary Raynaud's phenomenon

1. Primary Raynaud's phenomenon (PRP) is characterized by increased vasoconstrictor tone that develops during exposure to cold. The symptoms are most pronounced during the winter months with low outdoor temperature. The L-arginine-nitric oxide (NO)-cyclic GMP (cGMP) pathway plays an important role in counteracting vasospasm. The aim of the present study was to investigate if the venous cGMP respon

Non-invasive investigation of endothelium-dependent dilatation of the brachial artery in women with primary Raynaud's phenomenon

1. Primary Raynaud's phenomenon is characterized by white fingers and toes with impaired perfusion in response to cold or emotional stress. The aetiology has not been clarified. In previous studies we have demonstrated a season-linked inability in women with primary Raynaud's phenomenon to raise their plasma cGMP levels in response to whole-body cooling, suggesting a dysfunction of the L-arginine-
