Heat transfer deterioration in upward and downward pipe flows of supercritical n-decane for actively regenerative cooling

In this paper, we consider the flow and heat transfer behaviour of turbulent upward and downward flows of supercritical n-decane, in order to reveal the features of heat transfer deterioration (HTD) that would be expected in relevant active regenerative cooling systems for scramjet engines. Specific focus is placed on key velocity-field features that appear in these flows. Following the validation

Topology optimization of bistable elastic structures — An application to logic gates

In this paper, bistable gates which can be used as building blocks in logic gates are designed using topology optimization. The gate simulation is based on finite strain kinematics and hyperelastic material response. The objective of the optimization is to maximize the stiffness of a gate in the stable configurations while ensuring an adequate energy and distance separations between them and const

Diffusion of biogas for freight transport in Sweden : A user perspective

Current freight transport is highly dependent on fossil fuels and there is a need for a transition to alternative fuels and technologies. Biogas is a type of biofuel that has the potential to reduce climate emissions from freight transport, while providing additional benefits such as recycling of nutrients and increased energy security. This paper uses theories on the diffusion of green technologi

Diffusion-informed spatial smoothing of fMRI data in white matter using spectral graph filters

Brain activation mapping using functional magnetic resonance imaging (fMRI) has been extensively studied in brain gray matter (GM), whereas in large disregarded for probing white matter (WM). This unbalanced treatment has been in part due to controversies in relation to the nature of the blood oxygenation level-dependent (BOLD) contrast in WM and its detectability. However, an accumulating body of

Probabilistic approach to geomagnetic field modelling of data with age uncertainties and post-depositional magnetisations

Holocene geomagnetic field models are used to study processes in Earth's core, millennial scale variations in solar activity and to relatively date geological and archaeological archives. Constructing models from magnetic field directions and intensities stored in archaeological artefacts, igneous rocks and sediment records is challenging due to the sparse data distribution and the large chronolog

The γ-tubulin meshwork assists in the recruitment of PCNA to chromatin in mammalian cells

Changes in the location of γ-tubulin ensure cell survival and preserve genome integrity. We investigated whether the nuclear accumulation of γ-tubulin facilitates the transport of proliferating cell nuclear antigen (PCNA) between the cytosolic and the nuclear compartment in mammalian cells. We found that the γ-tubulin meshwork assists in the recruitment of PCNA to chromatin. Also, decreased levels

Plastic dinosaurs : Digging deep into the accelerating carbon lock-in of plastics

The continued expansion of plastics production all over the world entrenches modern societies and life styles deeper in the dependence on fossil resources. This research note develops the main aspects of the carbon lock-in in the plastics industry and how it extends into many aspects of contemporary life. With data collected from trade press and reports, we present insights of the investment trend

In Absence of a Working Place : A Gig Worker’s Sense Making of Work Community

In recent years, gig work – short-term and temporary assignments mediated via digital platforms – has captured the interest of media and research and is growing as an area of academic inquiry. Previously research has mainly focused on the regulations and breadth of gig work. Gig work can be been understood as a significant break from ‘standard employment relationship’, meaning that we are now headIn recent years, gig work – short-term and temporary assignments mediated via digital platforms – has captured the interest of media and research and is growing as an area of academic inquiry.

Predictors of unacceptable pain with and without low inflammation over 5 years in early rheumatoid arthritis-an inception cohort study

OBJECTIVES: Pain is a major symptom in patients with rheumatoid arthritis (RA). In early RA, pain is usually due to synovitis, but can also persist despite effective anti-inflammatory treatment. The objective of this study was to investigate the pain course over time and predictors of unacceptable pain and unacceptable pain with low inflammation, in patients with early RA.METHODS: An inception coh
