Active prechamber spark-ignition engines are a feasible and effective solution in reducing fuel consumption and pollutant emissions for internal combustion engines. However, reliable and low-cost numerical approaches need to be developed to support and speed-up their industrial design, considering their geometric complexity and the involved multiple-flow length scales. In this work, a computationa

Wind, rain, herbivores, obstacles, neighbouring plants, etc. provide important mechanical cues to steer plant growth and survival. Mechanostimulation to stimulate yield and stress resistance of crops is of significant research interest, yet a molecular understanding of transcriptional responses to touch is largely absent in cereals. To address this, we performed whole-genome transcriptomics follow

De vanligaste kontakterna under vikingatiden ur ett svenskt perspektiv gick österut. Miljontals islamiska mynt flödade in i Skandinavien från Nordafrika, kalifatet och det samanidiska herraväldet i Centralasien. Deras ursprung varierade, och silverströmmens kronologi gör det möjligt att beskriva föränderliga relationer mellan aktörerna. Några välkända artefakter från samma riktning kom till SkandiThe most common contacts during the Viking Age from a Swedish perspective were to the East. Millions of Islamic coins flowed into Scandinavia from North Africa, the Caliphate, and the Samanid dominion in Central Asia. Their origins differed, and the temporality of the silver stream makes it possible to outline changing interfaces between the actors. Some well known artifacts from the same directio

Multiple variables determine the success of an escape response of an animal, and the rapidity of the escape manoeuvre is often the most important. Fan worms (Annelida: Sabellidae) can rapidly withdraw their tentacles, which are covered in heavily ciliated ramifications called pinnules, into their tubes to protect them from approaching threats. Here, we explore the dynamic and mechanistic features

We employ a battery of model evaluation tests for a broad set of GARCH-MIDAS models and account for data snooping bias. We document that inferences based on standard tests for GM variance components can be misleading. Our data mining free results show that the gain of macro-variables in forecasting total (long-run) variance by GM models is overstated (understated). Estimation of different componen

Asthma and chronic rhinosinusitis with nasal polyps (CRSwNP) or without (CRSsNP) are chronic respiratory diseases. These two disorders often co-exist based on common anatomical, immunological, histopathological, and pathophysiological basis. Usually, asthma with comorbid CRSwNP is driven by type 2 (T2) inflammation which predisposes to more severe, often intractable, disease. In the past two decad

Detta kapitel introducerar queera perspektiv på global politik med utgångspunkt i en diskussion om politisk mobilisering kring hbtq-frågor på nationell och transnationell nivå. Att diskutera global politik utifrån ett queerperspektiv handlar inte enbart om att ”lägga till” hbtq-personer. Snarare innebär en queer analys att kritiskt granska vissa av de antaganden kring säkerhet, makt och förtryck s

Energy from buildings accounts for almost 40% of global energy-related carbon emissions. A way to reduce both energy consumption in buildings as well as their environmental impact is to use bio-based insulation materials such as cellulose, wood or hemp fiber insulation. Experiences from modern buildings built with a timber-frame structure and insulated with bio-based materials show that these buil

Detta arbete har utvärderat hastighetssäkrade åtgärders effekt på landsbygdsvägar genom att filma totalt 34 olika sådana åtgärder i södra Sverige och studera hastigheten av frigående bilar och tunga fordon när de passerar de olika åtgärderna.Varje plats har filmats med drönare och alla fordon har automatiskt spårats m.h.a. videoanalys. Därefter har frigående fordon identifierats och deras hastighe

Aims/hypothesis: Islet autoimmunity may progress to adult-onset diabetes. We investigated whether circulating odd-chain fatty acids (OCFA) 15:0 and 17:0, which are inversely associated with type 2 diabetes, interact with autoantibodies against GAD65 (GAD65Ab) on the incidence of adult-onset diabetes. Methods: We used the European EPIC-InterAct case–cohort study including 11,124 incident adult-onse

The stomatopod is a fascinating animal that uses its weaponized appendage dactyl clubs for breaking mollusc shells. Dactyl clubs are a well studied example of biomineralized hierarchical structures. Most research has focused on the regions close to the action, namely the impact region and surface composed of chitin and apatite crystallites. Further away from the site of impact, the club has lower
