In-situ quantification of spatiotemporally resolved particle concentration in iron powder combustion using holographic imaging

In-situ quantification of particle concentration during the combustion of solid fuel powders is of importance for analyzing their combustion behaviors. Digital holography (DH) is applied here for studying iron powder combustion at high concentration. The performance of DH as a function of particle concentration is thoroughly studied with synthetic holograms. The detection efficiency is found to be

High CD34 surface expression in BCP-ALL predicts poor induction therapy response and is associated with altered expression of genes related to cell migration and adhesion

Minimal residual disease (MRD) constitutes the most important prognostic factor in B-cell precursor acute lymphoblastic leukemia (BCP-ALL). Flow cytometry is widely used in MRD assessment, yet little is known regarding the effect of different immunophenotypic subsets on outcome. In this study of 200 BCP-ALL patients, we found that a CD34-positive, CD38 dim-positive, nTdT dim-positive immunophenoty

Grain boundary stiffness based on phase field crystal simulations

Phase field crystal modeling with wavelet filtering is shown to be an attractive replacement for molecular dynamics simulations when evaluating grain boundary stiffness by the capillary fluctuation method. Obstacles such as iterative equilibration of grain boundary structures and repeated reconstruction of the grain boundary over extended simulations can be avoided.

When librarians speak up : justifications for and legitimacy implications of librarians' engagement in social movements

Purpose: This article presents a discussion of how librarians' engagement in certain social movements manifests itself in public libraries, how librarians justify their engagement with specifically the LGBT + movement and the climate movement and what it might entail in terms of legitimacy. Design/methodology/approach: Besides an extensive international literature on libraries and climate/LGBT + i

Hyperhomocysteinemia and the MTHFR C677T mutation in central retinal vein occlusion

BACKGROUND: Hyperhomocysteinemia is a factor that predisposes to thrombosis, and the C677T mutation in methylene-tetrahydrofolate reductase (MTHFR) is known to give increased plasma homocysteine. We wanted to investigate if these factors were overrepresented in a group of patients with central retinal vein occlusion.METHODS: 116 patients with a history of central retinal vein occlusion were examin

Geographic distribution of the 20210 G to A prothrombin variant

A variant in prothrombin (clotting factor II), a G to A transition at nucleotide position 20210, has recently been shown to be associated with the prothrombin plasma levels and the risk of both venous and arterial thrombosis. The purpose of this study was to investigate the prevalence of carriership of this mutation in various populations. We combined data from 11 centres in nine countries, where

The amino-terminal module of the C4b-binding protein alpha-chain is crucial for C4b binding and factor I-cofactor function

C4b-binding protein (C4BP) regulates the classical pathway C3-convertase of the complement system. Human C4BP is composed of seven identical subunits (alpha-chains) and one unique one (beta-chain). Both types of chains contain homologous repeats called complement control proteins (CCPs); the alpha-chain contains eight CCPs and the beta-chain three. Each alpha-chain contains a binding site for C4b

A niche technique overlooked in the Danish district heating sector? Exploring socio-technical perspectives of short-term thermal energy storage for building energy flexibility

This research explores socio-technical perspectives of the demand-side management strategy of using the built environment for short term thermal energy storage. Here conceptualised as a niche innovation within the Danish socio-technical district heating landscapes, the research explores potentials and limitations of this building energy flexibility strategy from the perspective of district heating

Organic micropollutants, heavy metals and pathogens in anaerobic digestate based on food waste

Anaerobic digestate based on food waste is increasingly used as fertilizer in food production. This study examined the characteristics of anaerobic digestate based on food waste from three biogas plants in Sweden. The characterization included measurements of heavy metals (n = 7), chemicals of emerging concern (CECs), such as currently used drugs and pesticides (n = 133), and an extended range of

Uncle Tall Tale : On “Mo Yan Speaks: Lectures and Speeches by the Nobel Laureate from China”

ALTHOUGH MO YAN’S claim to fame is undoubtedly as the Nobel laureate from China, the 23 public lectures gathered in Mo Yan Speaks present a truly “glocal” writer who has one literary foot firmly planted in the soil of his native Gaomi Township and the other tiptoeing into the arena of world literature. They show an author performing a balancing act between his international elite status and the lo

Linking innovations and patents - a machine learning assisted method

This paper describes the methodology behind the matching of patents and a literature-based innovation output indicator (LBIO) collected from trade journals covering the manufacturing and ICT service sectors in Sweden 1970-2015. A combination of manual processing and simple machine learning tools has enabled the identification, classification and linking of patents that otherwise would have been ve

Contribution of child ABC-transporter genetics to prenatal MeHg exposure and neurodevelopment

BACKGROUND: There is emerging evidence that exposure to prenatal methylmercury (MeHg) from maternal fish consumption during pregnancy can differ between individuals due to genetic variation. In previous studies, we have reported that maternal polymorphisms in ABC-transporter genes were associated with maternal hair MeHg concentrations, and with children's early neurodevelopmental tests. In this st

Laser-induced fluorescence for studying the influence of potassium and sodium salts on PAH formation in sooting premixed flames

Previous studies have shown that alkali salts influence combustion processes and soot formation, although the effects seem to vary across systems. Moreover, fundamental studies on the effect of potassium and sodium salts on formation of polycyclic aromatic hydrocarbons (PAH), which are precursors in soot formation, are scarce. Here, we report a study in which the effects on PAH formation due to th

Towards engineered yeast as production platform for capsaicinoids

Capsaicinoids are bioactive alkaloids produced by the chili pepper fruit and are known to be the most potent agonists of the human pain receptor TRPV1 (Transient Receptor Potential Cation Channel Subfamily V Member 1). They are currently produced by extraction from chili pepper fruit or by chemical synthesis. Transfer of the biosynthetic route to a microbial host could enable more efficient capsai

Förvaltningsorgan under parlamenten i Norden

I de nordiska länderna finns ett antal förvaltningsorgan som på olika sätt är knutna till parlamenten. Hit hör exempelvis Folketingets Ombudsmand(Danmark), Statens revisionsverk (Finland), Ríkisendurskoðun(Riksrevisionen, Island), Stortingets kontrollutvalg for etterretnings-,overvåkings- og sikkerhetstjeneste, EOS-utvalget (Norge) och Valprövningsnämnden (Sverige). Sådana organ kan ses som en avvIn a Western European system based on a traditional separation of powers, public administration is as a rule organised under the Government (or Cabinet), as part of the Executive. In addition to this kind of state authorities, the Nordic countries feature a number of administrative bodies attached to the Parliaments. This category includes Parliamentary Ombudsmen, National Banks, and National Audi
