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
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
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
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
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
Bakgrund Den 20 januari 2020 senarelades ålderspensionen i Sverige för alla yrkesgrupper. Samtidigt ökar den arbetsrelaterade sjukligheten. I ett framtidsperspektiv kommer efterfrågan på arbetskraft som kan och vill arbeta till en högre ålder att öka utifrån den globala demografiska förändringen. Att medverka till en god anställningsbarhet (employability) och hälsa är därför en central fråga och uHållbart arbetsliv för alla åldrar – swAge modellenKerstin Nilsson1, 21Högskolan Kristianstad, 2Lunds universitetBakgrundDen 20 januari 2020 senarelades ålderspensionen i Sverige för alla yrkesgrupper.

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 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.

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
