Purpose: This paper aims to comprehensively clarify the research status of thermal transport of supercritical aviation kerosene, with particular interests in the effect of cracking on heat transfer. Design/methodology/approach: A brief review of current research on supercritical aviation kerosene is presented in views of the surrogate model of hydrocarbon fuels, chemical cracking mechanism of hydr

The COVID-19 pandemic and its impact on society has been suspected to affect gambling behaviors. Potentially, the pandemic crisis may result in increased problem gambling, for example, due to COVID-19-related psychological distress, unemployment, and financial difficulties. In ad-dition, the cancellation of sports in early parts of the crisis has been suspected to alter gambling behaviors. Policy

X-ray phase-contrast imaging by grating interferometry has in the past decades been established both at synchrotron radiation sources and at conventional x-ray tubes. Due to the sensitivity to x-ray phase shifting, contrast in soft tissue has been improved significantly and the possibilities to do virtual histology of tissue biopsies are being pioneered. Constraints in the design of a grating inte

This paper focuses on the intersection of social dynamics, knowledge production, and the implementation of identity features in robotic platforms. Concentrating on the concept of epistemic injustice, particularly in the context of trust, the study highlights the potential for justified distrust based on experienced injustice. The incorporation of social identity features, such as gender, signals g

Microbicides in the leather industries are employed to avoid the biodeterioration of the hides by microorganisms. This problem may lead to harmful characteristics to the end product such as stains, roughness and decrease mechanical properties of leather. Therefore, microbicides like the 2-(thiocyanomethylthio) benzothiazole (TMCTB) are applied in distinct steps of the tanning process as alternativ

Popular Abstract in Swedish Bilsäten har genomgått en kontinuerlig utveckling ända sedan de först beskrevs år 1885. På den tiden kunde man läsa om vadderade läderbänkar, monterade på stora fjädrar, fastsatta i chassit på ”hästlösa vagnar”. När polyuretanskum först började tillverkas på 1950-talet introducerades de snabbt i bilsätena och dessa genomgick stora förbättringar. Skummen utgör idag en stAutomotive seating has been under continous development since it was described for the first time in 1885. At that time one could read about a “padded leather bench seat sitting on springs mounted directly to the frame of a horse-less carriage”. With the development of flexible polyurethane foam in 1950-1960 the seats were considerably improved and the traditional springs were eventually replaced

Ta några ingenjörsstudenter, släng in ett par kognitionsvetarstudenter och ge dem ett problem att lösa. Ut kommer interaktiva dataspel för skolan och robotar som kan imitera människors rörelser. – Vi kombinerar doing och thinking, säger Agneta Gulz, professor i kognitionsvetenskap.

Popular Abstract in Swedish Populärvetenskaplig sammanfattning Utvecklingen av nya innovativa chokladprodukter har tagit fart under de senaste åren i takt med att konsumenterna ställer allt högre krav på chokladkvaliteten. Eftersom produktionsprocessen är komplicerad och hållbarhetstiden begränsad uppskattas att man slänger drygt 100 000 ton chokladprodukter varje år i Europa till ett värde av 1.Abstract Fat bloom on chocolate is a major problem for the confectionery industry since the unappetising appearance and negative sensory effects lead to rejection by customers. The presence of fat bloom on chocolate confectionery systems is usually connected to migration of liquid fat due to the difference in composition between filling triacylglycerols (TAGs) and cocoa butter TAGs. The filling T

Phasor measurement signals are used as only input to a wide-area power system stabilizer to increase interarea mode damping of the Icelandic system. Modal analysis and time simulations of a detailed model show that frequency difference as PSS input gives a damping improvement that is robust to drastic changes in system topology. Field data from phasor measurement units indicate high signal quality
