Osborn waves following out-of-hospital cardiac arrest—Effect of level of temperature management and risk of arrhythmia and death

Background: The Osborn or J-wave, an upright deflection of the J-point on the electrocardiogram (ECG), is often observed during severe hypothermia. A possible relation between Osborn waves (OW) and increased risk of ventricular arrhythmia has been reported. We sought to determine whether the level of targeted temperature management (TTM) following out-of-hospital cardiac arrest (OHCA) affects the

Impact of Rye Kernel-Based Evening Meal on Microbiota Composition of Young Healthy Lean Volunteers With an Emphasis on Their Hormonal and Appetite Regulations, and Blood Levels of Brain-Derived Neurotrophic Factor

Rye kernel bread (RKB) evening meals improve glucose tolerance, enhance appetite regulation and increase satiety in healthy volunteers. These beneficial effects on metabolic responses have been shown to be associated with increased gut fermentation. The present study aimed to elucidate if RKB evening meals may cause rapid alterations in microbiota composition that might be linked to metabolic-, im

Monthly runoff prediction using phase-space reconstruction

A nonlinear prediction method, developed based on the ideas gained from deterministic chaos theory, is employed: (a) to predict monthly runoff; and (b) to detect the possible presence of chaos in runoff dynamics. The method first reconstructs the single-dimensional (or variable) runoff series in a multi-dimensional phase space to represent its dynamics, and then uses a local polynomial approach to

Brännässlor–inte bara ogräs

Stinging nettles are not always appreciated, but have been used for spinningyarn and weaving since the Bronze Age, and have also been much used in folk medicine. They are used as food for caterpillars of several of our most beloved butterflies, but area lso victims of an interesting parasitic plant, the dodder.And they can be used to make a delicate soup!

Is familial risk for depression confounded by individual and familial socioeconomic factors and neighborhood environmental factors? A 7-year follow-up study in Sweden

Family history of depression is an important risk factor for depression. The aim of this study was to examine whether the effect of family history of depression is confounded by individual and familial socioeconomic factors (i.e., country of origin, educational attainment, family income and mobility) and neighborhood environmental factors (i.e., neighborhood deprivation and neighborhood social cap

Formation of NO and NH in NH3-doped CH4 + N2 + O2 flame : Experiments and modelling

Co-combustion of 5200 ppm NH3 with a stoichiometric, atmospheric pressure, CH4 + N2 + O2 flame has been investigated with experiments and kinetic modelling. Profiles of the amidogen (NH) radical and nitric oxide (NO) have been measured using laser-induced fluorescence, the latter being quantitatively determined. Temperature profiles were measured using Rayleigh scattering and thermocouple, the non

Human igg increases virulence of streptococcus pyogenes through complement evasion

Streptococcus pyogenes is an exclusively human pathogen that can provoke mild skin and throat infections but can also cause fatal septicemia. This gram-positive bacterium has developed several strategies to evade the human immune system, enabling S. pyogenes to survive in the host. These strategies include recruiting several human plasma proteins, such as the complement inhibitor, C4b-binding prot

Pedagogik som vetenskap. En inbjudan.

Pedagogik är en av de klassiska vetenskapliga disciplinerna och har som universitetsämne en hundraårig tradition. I takt med att samhället förändras har även det innehåll som sysselsätter pedagogiken ändrats. Var befinner sig det vetenskapliga ämnet pedagogik i dag? Hur ser den historiska bakgrunden till ämnets framväxt ut? Vilka är de fundament som håller samman pedagogikämnet? Vilka framtida utm

Validation of Phase Contrast Flow Quantification and Relaxometry for Cardiovascular Magnetic Resonance Imaging

Quantitative imaging, where every pixel of an image represents a physical quantity (e.g. timeor velocity) is being increasingly used in the field of diagnostic radiology and has potential toenhance medical diagnosis. Quantitative methods for Magnetic Resonance Imaging (MRI)enables measurements of velocity and flow using a technique called Phase Contrast MagneticResonance (PC-MR), and different tim

Characterization of Irreversible Fouling after Ultrafiltration of Thermomechanical Pulp Mill Process Water

Large volumes of wastewater with dissolved wood components are treated in wastewater treatment plants at thermomechanical pulp mills. It has been shown previously that hemicelluloses in these wastewater streams can be recovered by membrane filtration. A serious obstacle when treating lignocellulose process streams is fouling of the membranes. Fouling not only increases operating costs but also red

Modeling plot scale dye penetration by a diffusion limited aggregation (DLA) model

Solute transport in the unsaturated zone often occurs in preferential How paths. There are several reasons for this, e.g., water repellency, the occurrence of fissures and cracks, animal borrows, decomposed root threads etc. The resulting How patterns often display a fractal resemblance which is difficult to predict using conventional transport models. A way to preserve the fractal property of obs

The radial extent of the Galactic thick disk

Based on observational data from the fourth internal data release of the Gaia-ESO Survey we probe the abundance structure in the Milky Way stellar disk as a function of galactocentric radius and height above the plane. We find that the inner and outer Galactic disks have different chemical signatures. The stars in the inner Galactic disk show abundance signatures of both the thin and thick disks,

Understanding one's body and movements from the perspective of young adults with autism : A mixed-methods study

Background: There are but a few studies of how persons with autism perceive their bodies and movements. Difficulties in perceiving the surrounding world along with disturbed motor coordination and executive functions may affect physical and psychological development. Aims: To explore the experiences of body and movements in young adults with autism and how two physiotherapeutic instruments may cap

Collective Incentives and Cooperation in Teams with Imperfect Monitoring

We experimentally explore the role of collective incentives in sustaining cooperation in finitely repeated public goods games with imperfect monitoring. In our experiment players only observe noisy signals about individual contributions, while total output is perfectly observed. We consider sanctioning mechanisms that allow agents to commit to collective punishment in case total output fall short

A long-lasting taxonomic problem in European Sympycnus resolved, with the description of a new species and data on habitat preferences

Type specimens of Sympycnus pulicarius, S. annulipes, S. cinerellus and S. desoutteri were examined to clear up a long-lasting taxonomic confusion. Our study revealed that they represent, together with S. pygmaeus and S. annulipes var. brunnitibialis, a single species, with S. pulicarius as the senior subjective synonym, which is redescribed in this paper. Lectotypes were designated for Dolichopus

No special treatment of independent object motion for heading perception

How do we judge the direction of self-motion (i.e., heading) in the presence of independent object motion? Previous studies that examined this question confounded the effects of a moving object's speed and its position on heading judgments, and did not examine whether the visual system uses salient nonmotion visual cues (such as color contrast and binocular disparity) to segment a moving object fr

The opportunity prior : A simple and practical solution to the prior probability problem for legal cases

One of the greatest impediments to the use of probabilistic reasoning in legal arguments is the difficulty in agreeing on an appropriate prior probability for the ultimate hypothesis, (in criminal cases this is normally “Defendant is guilty of the crime for which he/she is accused”). Even strong supporters of a Bayesian approach prefer to ignore priors and focus instead on considering only the lik
