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

Gruppen är grejen: En reflexiv tematisk analys av hur personer inom ångest- och förstämningsspektrumen upplever och tillskriver betydelse till Compassion Focused Therapy som gruppbehandling i en svensk primärvårdskontext.

Denna studie syftade till att fördjupa förståelsen av hur personer inom ångest- och förstämningsspektrumen upplevde och tillskrev betydelse till Compassion Focused Therapy (CFT) som gruppbehandling i en svensk primärvårdskontext. Materialet utgjordes av 12 semistrukturerade intervjuer med deltagare som genomgått CFT-gruppterapi på en vårdcentral i södra Sverige. Genom reflexiv tematisk analys geneThis study aimed to deepen the understanding of how people within the anxiety and depression spectrums experienced and attributed meaning to Compassion Focused Therapy (CFT) as a group treatment in a Swedish primary care context. The material consisted of 12 semi-structured interviews with participants who had undergone CFT group therapy at a health center in southern Sweden. Through reflexive the

Integrering av humaniora i läkar- och ingenjörsutbildning : En bild av forskningsläget och riktningar för vidare forskning

De senaste 20 åren har humanioraintegrering i professionsutbildning varit på frammarsch i Sverige, både som forskningsfält och högskolepedagogisk praktik. Detta syns bland annat på bildandet av ett antal tvärvetenskapliga centra och program med sådan integrering i fokus. Den akademiska litteraturen om humanioraintegration i professionsutbildning visar att utvecklingen i Sverige är en del av en int

The Dynamics of Detach and Connect when using Autobiography in Professional Education

The paper reports on preliminary findings from a case study of an autobiography-based course element included in the social work professional education program of a Swedish university. In the studied course element, the aim was for autobiographies to provide a platform and catalyst for student reflections on client perspectives as well as for reflexivity in relation to students’ own frames of refe

Narrative Art as a Pedagogical Tool in Professional Ethics Education

Research topic/aim:The purpose of this paper is to contribute empirically to the ongoing academic discussion about the meaningful implementation of narrative art as a pedagogical tool in professional ethics education (PEE). In the present work, meaningfulness is conceived of as connectedness, and narrative art includes literary fiction and autobiography. Research questions are:How do students in e

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

Spanning Divides : Prospecting, Facilitating, and Building Narrative Bridges in Interdisciplinary Professional Education

This paper addresses the use of narrative in interdisciplinary professional education as a device for the reciprocal transfer of knowledge, insights, or methods between persons and knowledge domains, but also for their integration and transformation into burgeoning professional judgement. The paper considers an elective course for engineering students, in which emerging technology ethics are appro

Large Eddy Simulation of a model jet-engine swirl-stabilized flame using sustainable aviation fuels

Sustainable Aviation Fuels (SAF) typically exhibit a composition that differs significantly from conventional jet fuels. These variations in chemical makeup influence the thermophysical and reactive properties of these propellants. In this study, Finite-Rate Chemistry (FRC) Large Eddy Simulations (LES) are employed to investigate turbulent spray flames from a Triple Annular Research Swirler (TARS)

Multidimensional chemistry coordinate mapping for Large Eddy Simulations of a turbulent premixed bluff-body burner

In numerical combustion research, accurate chemical reaction mechanisms for heavy hydrocarbons are essential to investigate the flame dynamics of Sustainable Aviation Fuels (SAF) relative to conventional jet fuels. However, accounting for hundreds or thousands of reactions makes Finite-Rate Chemistry (FRC) Large Eddy Simulations (LES) impractical for realistic engineering scenarios. In the present

Barnmorskors erfarenheter av att tala om sex och samliv vid eftervårdsbesöket postpartum - En kvalitativ intervjustudie

Bakgrund: Barnmorskan ska arbeta hälsofrämjande för kvinnors sexuella och reproduktiva hälsa och kunna identifiera avvikelse, samt besitta kunskap kring kvinnors sexuella hälsa genom hela livet. På eftervårdsbesöket 6-8 veckor postpartum ska barnmorskan enligt Region Skånes basprogram för graviditet och eftervård belysa frågor kring samliv samt ge rådgivning. Studier har visat att kvinnor upplever

Möjligheter och begränsningar med termografi som metod för broinspektion

Denna studie undersöker möjligheter och begränsningar med termografi som metod för broinspektion, med fokus på dess förmåga att identifiera skador och fukt i betongkonstruktioner. Metoden utvärderas både utifrån vilka typer av skador som kan detekteras och hur omgivningsfaktorer påverkar mätresultaten. Vidare undersöks potentialen i att använda maskininlärning för att automatiskt identifiera skadoThis study examines the opportunities and limitations of thermography as a method for bridge inspections, focusing on its ability to identify defects and moisture in concrete structures. The method is evaluated based on the types of defects that can be detected and how environmental factors influence the results. Furthermore, the study explores the potential of using machine learning to automatica

On the influence of carbides in laser-cladded coating on friction, wear, and airborne particle emissions of disc brakes

Recently, it has become a focus to reduce non-exhaust aerosol emissions from the transport sector. One possible way to decrease brake particle emissions is by laser-cladding coatings onto brake discs. This work tested five different laser-cladding coated brake discs against a non-asbestos organic brake pad. The performance of these coatings was compared to a commercial grey cast iron brake disc te

Combining DNA metabarcoding with macroscopic analysis increases the number of detected prey taxa in the estimated diet for harbour porpoises

Knowledge of animal diets is fundamental in ecology as it can provide insight into the structure, function and resilience of entire ecosystems. In this study we investigate the diet composition of the harbour porpoise (Phocoena phocoena), a small marine top predator with great ecological importance, to provide updated dietary estimates for the species in Swedish waters. This is done by parallel us

Thermomechanical process modelling and simulation for additive manufacturing of nanoparticle dispersed Inconel 718 alloys

In this study, a coupled transient thermomechanical finite element model is developed to examine the laser powder bed fusion (L-PBF) process of the Inconel 718 (IN718) and Oxide Dispersion Strengthened (ODS) superalloys (ODS-IN718). The linear isotropic elastic perfectly plastic constitutive model is implemented for the mechanical part whereas all the thermophysical properties are defined as fully

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

Affective Collecting : Ethics, Emotions, and Collecting the Holocaust

Before curation, there is collection. Before visitors engage with objects in an exhibition, collection managers engage with the objects and, in some cases, also the donors. It makes sense that especially when difficult pasts are involved, collection managers have affective encounters with the materiality before visitors do. So why has the affective turn focused mainly on engaging visitors’ emotion
