French is characterized by major differences between phonology and orthography. Consequently, learning the deep orthography of written French is a challenge to both first (L1) and second (L2) language learners. This empirical study focuses on the production of silent number morphology in written French and illustrates that a group of L2 learners, exposed to limited amounts of spoken French in a ty

Capturing our cultural intangible textile heritage : Mocap and craft technology

Textile craft and textile design have always had an important social, cultural and economic impact on both individuals and societies. The cultural heritage of textiles does not end with the preservation and collection of costumes and other textiles in museums. It also includes living traditions inherited from our ancestors. Furthermore, understanding craft and craft processes are crucial when cons

Regional disparities in the beneficial effects of rising CO2 concentrations on crop water productivity

Rising atmospheric CO2 concentrations ([CO2 ]) are expected to enhance photosynthesis and reduce crop water use. However, there is high uncertainty about the global implications of these effects for future crop production and agricultural water requirements under climate change. Here we combine results from networks of field experiments and global crop models to present a spatially explicit global

Atomistic characterization of the active-site solvation dynamics of a model photocatalyst

The interactions between the reactive excited state of molecular photocatalysts and surrounding solvent dictate reaction mechanisms and pathways, but are not readily accessible to conventional optical spectroscopic techniques. Here we report an investigation of the structural and solvation dynamics following excitation of a model photocatalytic molecular system [Ir 2 (dimen) 4 ] 2+, where dimen is

Inferring 222Rn soil fluxes from ambient 222Rn activity and eddy covariance measurements of CO2

We present a new methodology, which we call Single Pair of Observations Technique with Eddy Covariance (SPOT-EC), to estimate regional-scale surface fluxes of 222Rn from tower-based observations of 222Rn activity concentration, CO2 mole fractions and direct CO2 flux measurements from eddy covariance. For specific events, the regional (222Rn) surface flux is calculated from short-term changes in am

Path loss models with distance-dependent weighted fitting and estimation of censored path loss data

Path loss models are the most fundamental part of wireless propagation channel models. Path loss is typically modelled as a (single-slope or multi-slope) power-law dependency on distance plus a log-normally distributed shadowing attenuation. Determination of the parameters of this model is usually done by fitting the model to results from measurements or ray tracing. The authors show that the typi

Analysis of complement biomarkers in systemic sclerosis indicates a distinct pattern in scleroderma renal crisis

Background: The complement system has been implicated in pathogenesis of systemic sclerosis (SSc). The goal of the present study was to evaluate improved complement biomarkers in SSc. Methods: The presence of C4d, reflecting activation of the classical/lectin pathways, C3bBbP corresponding to activation of the alternative pathway, and soluble terminal complement complexes (all complement pathways)

Physical Activity During Growth. Effects on Bone, Muscle, Fracture Risk and Academic Performance

Frakturer är ett stort och dessutom ökande samhällsproblem. Genom att stärka skelettet och muskulaturen kan risken för frakturer minskas. Hög fysisk aktivitet är associerad med hög benmassa, gynnsam skelettstruktur, god muskelfunktion och låg risk att drabbas av frakturer. Fysisk aktivitet skulle därför kunna vara en möjlig strategi för att minska antalet frakturer i samhället. Tidigare forskning

Anaerobic poly-3-d-hydroxybutyrate production from xylose in recombinant Saccharomyces cerevisiae using a NADH-dependent acetoacetyl-CoA reductase

Background: Poly-3-d-hydroxybutyrate (PHB) that is a promising precursor for bioplastic with similar physical properties as polypropylene, is naturally produced by several bacterial species. The bacterial pathway is comprised of the three enzymes β-ketothiolase, acetoacetyl-CoA reductase (AAR) and PHB synthase, which all together convert acetyl-CoA into PHB. Heterologous expression of the pathway

ANLN is a prognostic biomarker independent of Ki-67 and essential for cell cycle progression in primary breast cancer

Background: Anillin (ANLN), an actin-binding protein required for cytokinesis, has recently been presented as part of a prognostic marker panel in breast cancer. The objective of the current study was to further explore the prognostic and functional value of ANLN as a single biomarker in breast cancer. Methods: Immunohistochemical assessment of ANLN protein expression was performed in two well cha

Effects of the web behavior change program for activity and multimodal pain rehabilitation : Randomized controlled trial

Background: Web-based interventions with a focus on behavior change have been used for pain management, but studies of Web-based interventions integrated in clinical practice are lacking. To emphasize the development of cognitive skills and behavior, and to increase activity and self-care in rehabilitation, the Web Behavior Change Program for Activity (Web-BCPA) was developed and added to multimod

Studies of electron diffusion in photo-excited Ni using time-resolved X-ray diffraction

We show that the heat deposition profile in a laser-excited metal can be determined by time-resolved X-ray diffraction. In this study, we investigated the electron diffusion in a 150 nm thick nickel film deposited on an indium antimonide substrate. A strain wave that mimics the heat deposition profile is generated in the metal and propagates into the InSb, where it influences the temporal profile

Different expression levels of glycans on leukemic cells—a novel screening method with molecularly imprinted polymers (MIP) targeting sialic acid

Sialic acid (SA) is normally expressed on the cell membranes and is located at the terminal position of the sugar chains. SA plays an important role for regulation of the innate immunity, function as markers of the cells and can be recognized by a variety of receptors. Interestingly, the level of SA expression is increased on metastatic cancer cells. The availability of specific antibodies against

Physiotherapy students' perceptions of learning in clinical practice in Sweden and India

BACKGROUND: It is reasonable to assume that conditions for learning differ between universities and countries. Increased understanding of similarities and differences of student's perceptions of learning environment can be useful in the development of the physiotherapy education as well as of the profession as such. Through international comparisons the benefits and challenges of educational progr

MAX IV is Ready to Make the Invisible Visible

In a ceremony held on June 21, the brightest day of the year in the northern hemisphere, Swedish Prime Minister Stefan Löfven and H.M. King Carl XVI Gustaf, together with Director Christoph Quitmann, inaugurated MAX IV Laboratory in the presence of about 500 staff, funders, stakeholders, and guests from all over the world.

Parent participation plays an important part in promoting physical activity

Although physical activity (PA) is an important and modifiable determinant of health, in Sweden only 15% of boys and 10% of girls aged 15 years old achieve the recommended levels of PA 7 days per week. Adolescents' PA levels are associated with social influence exerted by parents, friends, and teachers. The purpose of this study was to describe parents' experiences of being a part of their adolesc
