Phase Field Modelling of Formation and Fracture of Expanding Precipitates

It is a common belief that embedded expanding inclusions are subjected to an internal homogeneous compressive hydrostatic stress. Still, cracks that appear in precipitates that occupy a larger volume than the original material, are frequently observed. The appearance of cracks has since long been regarded as a paradox. In the present study it is shown that matrix materials that increases its volum

Master curve in upper region of ductile brittle transition : A modification based on local damage approach

The fracture behaviour of ferritic/ferritic martensitic steels in Ductile to Brittle Transition (DBT) region is well captured by Master Curve approach, except in the upper region of transition due to ductile tearing prior to cleavage. The fracture toughness behavior in the upper region of DBT is generally censored by Master Curve. In this work the Master Curve approach is modified to extend its a

A loss of constraint assessment using δ∗-π∗approach to describe the effect of crack depth on reference transition temperature T0

The assessment of fracture behaviour of ferritic/ferritic martensitic steels in Ductile to Brittle Transition (DBT) region iscrucial for shallower cracks. In this work the fracture behavior of In-RAFM steels isinvestigated with systematically varying a/W using Master Curve approach. This a/W effect is investigated using σ∗-V∗approach by calculating the active volume at simulated crack front. It i

E.coli bacteria attached to a sand grain : "Landing on a sand grain"

The movie shows E. coli bacteria (strain DSM 1116) attached to a grain of sand. The size of the sand grain is approx. 0.85 mm. The SEM (scanning electron microscope) pictures were taken within a laboratory experiment, measuring the influence of different concentration of E. coli bacteria to the Induced Polarization (IP) method in frequency- and time-domain (LINKIP project, funded by the European U

Our People a Tight-knit Family under the Same Protective Roof : A Critical Study of Gendered Conceptual Metaphors at Work in Radical Right Populism

De pågående globaliseringsprocesserna har gett upphov till ett allt större motstånd bland en påstådd homogen enhet som benämns vårt folk och som binder samman medborgarna som bebor landet och som delar dess politiska, sociala och kulturella egenskaper. I detta sammanhang har de högerradikala populistiska partierna som påstår sig försvara folkets verkliga politiska intressen och vilja fått en allt

Activation of AMP-activated protein kinase stimulates Na+,K +-ATPase activity in skeletal muscle cells

Contraction stimulates Na+,K+-ATPase and AMP-activated protein kinase(AMPK)activity in skeletal muscle. Whether AMPK activation affects Na+,K+-ATPase activity in skeletal muscle remains to be determined. Short term stimulation of rat L6 myotubes with the AMPK activator 5-aminoimidazole-4-carboxamide- 1-β-D-ribofuranoside (AICAR), activates AMPK andpromotes translocation of the Na+,K +-ATPase α1-su

Konstruktionen av högerradikala populistiska maskuliniteter i Sverige. En feministisk analys

Ov Cristian Norocels artikel diskuterar den svenska högerradikala populismenutifrån ett feministiskt perspektiv. Han kartlägger Sverigedemokraternas omtolkningar av den nationella metaforen om ”det svenska folkhemmet” och analyserar konstruktionen av maskuliniteter inom svensk högerradikal populism. Norocel för fram en specifik tolkning av den begreppsliga metaforteorin, en tolkning som innefattar

Opportunities and Challenges for GeoBIM in Europe: developing a building permits use-case to raise awareness and examine technical interoperability challenges

The integration of geoinformation with BIM (GeoBIM) is critical to underpin solutions to many city-related challenges. However, to achieve an effective integration it is necessary to consider not only data and technical options but also current practice and users’ needs. This paper describes work carried out within the EuroSDR-GeoBIM project to address this challenge. After investigating potential

Exploring and expanding improvisatory knowledge in musical practice

This project was carried out as a series of concerts and workshops of organ improvisation with six professional performers. The purpose was to further explore experiences made in the artistic research project Rethinking organ improvisation, which pointed at how improvisation differs in musical character and function between different performance contexts.Our aims were to •rethink improvisation in
