We report on VLT/GIRAFFE spectra of stars in two recently discovered ultra-faint satellites, Reticulum 2 and Horologium 1, obtained as part of the Gaia-ESO Survey. We identify 18 members in Reticulum 2 and five in Horologium 1. We find Reticulum 2 to have a velocity dispersion of 3.22(-0.49)(+1.64) km s(-1) , implying a mass-to-light ratio (M/L) of similar to 500. The mean metallicity of Reticulum
This article focuses on Olof von Dalin’s occasional verse, which has not yet been collected in a scholarly edition. Dalin's occasional poems have survived thanks to many people. Some of them were personal friends and acquaintances of his while others did not move in his circles and were not personally known to him. They copied his poems and in not a few cases made sure that they were printed; they
Popular Abstract in Swedish Varje år insjuknar omkring 300 barn i cancer. Förbättrade behandlingsmetoder under de senaste decennierna har lett till att mer än tre av fyra barn idag faktiskt botas från sin sjukdom. Tyvärr drabbas en stor andel av de som överlever sin cancer av så kallade sena komplikationer till följd av den tuffa behandling de har utsatts för. Bland annat har man sett en livslång The etiology of childhood cancer is largely unknown. Approximately 1-10% of all childhood tumors are associated with known cancer predisposition syndromes. However, the contribution may be underestimated due to the failure to detect patients with genetic susceptibility for cancer when relying on known family pattern and anomalies. Growing evidence indicates that patients with genetic susceptibilit
The terms “holism” and “interactionism” are central to the person-oriented approach, especially as formulated in Magnusson’s (2001) holistic-interactionistic paradigm. However, Nilsson (2015) has recently argued that at least some forms of holism and interactionism need to be disentangled. This raises some general questions about what is meant by “holism” and “interactionism” and whether there are
Topical negative pressure (TNP) treatment is a commonly used technique in the hospital care of acute or postoperative large, open wounds. In recent years the method has also been used to promote healing of so-called hard-to-heal ulcers, e.g. pressure ulcers, various leg ulcers, and diabetic foot ulcers. The SBU enquiry service has summarized the scientific literature on the clinical effects of TNP
Background: Prostate tumours are commonly poorly oxygenated which is associated with tumour progression and development of resistance to chemotherapeutic drugs and radiotherapy. Fibroblast growth factor 8b (FGF8b) is a mitogenic and angiogenic factor, which is expressed at an increased level in human prostate tumours and is associated with a poor prognosis. We studied the effect of FGF8b on tumour
Isla de los Estados (54A degrees 45'S, 63A degrees 10'aEuro"64A degrees 46'W) lies east of the main island of Tierra del Fuego and is the southeastern-most point in Argentina. Because of its geographic position near the latitudes of the Southern Hemisphere Westerlies and the strong influence of the Antarctic Circumpolar Current (ACC), the area is suitable for paleoecological and paleoclimate resea
Many commercial dye preparations are cocktails of active dyes and various by-products that are recalcitrant to biological degradation and end up in significant amounts in the effluent after the dyeing process. Conventional wastewater treatment processes are not able to degrade such compounds and detoxify the effluent, thus alternative treatments should be developed. In our work we suggest to use p
Structural equilibrium properties of transient networks formed by microemulsion droplets and ABA triblock copolymers in solution have been studied by Monte Carlo simulation. The droplets were represented by soft spheres and the polymers by junctions connected by harmonic bonds with an angular potential regulating the intrinsic chain stiffness. The interaction parameters were selected such that the
In this paper we introduce a new algorithm for seismic imaging based on the flow out of Gaussian wave packets. We follow the standard strategy of decomposing data into wave packets and flowing them out along rays to approximate the downward wavefield extrapolation, and finally applying an imaging condition. We revisit each computational step to gain efficiency. Furthermore, we develop procedure fo
MicroRNAs have emerged as important regulators of smooth muscle phenotype and may play important roles in pathogenesis of various smooth muscle related disease states. The aim of this study was to investigate the role of miRNAs for urinary bladder function. We used an inducible and smooth muscle specific Dicer knockout (KO) mouse which resulted in significantly reduced levels of miRNAs, including
In models of anomaly-mediated supersymmetry breaking (AMSB), the lightest chargino is predicted to have a lifetime long enough to be detected in collider experiments. This letter explores AMSB scenarios in pp collisions at root s = 7 TeV by attempting to identify decaying charginos which result in tracks that appear to have few associated hits in the outer region of the tracking system. The search
Background: The complexity and dynamical nature of community interactions make modelling a useful tool for understanding how communities develop over time and how they respond to external perturbations. Large community-evolution models (LCEMs) are particularly promising, since they can address both ecological and evolutionary questions, and can give rise to richly structured and diverse model comm
Objective To investigate whether the risk allele for systemic lupus erythematosus (SLE) in the signal transducer and activator of transcription factor 4 (STAT4) gene, defined by the single nucleotide polymorphism (SNP) rs10181656(G), is associated with vascular events and/or presence of prothrombotic anti-phospholipid antibodies (aPL) in patients with SLE. Methods Two independent groups of unrelat
Although no common genetic defect has been described in chronic lymphocytic leukemia (CLL), recurrent genomic aberrations (i.e. deletions of chromosome 11q, 13q, 17p and trisomy 12) are important for prognostication. Deletion of 13q as single aberration is associated with the best prognosis, whereas del(11q) and del(17p) predict a poor outcome. Recent development of high-resolution genomic techniq
For vehicles using grid power to charge the battery, traction circuit components are not engaged during the charging time, so there is a possibility to use them in the charger circuit to have an onboard integrated charger. The battery charger can be galvanically isolated or nonisolated from the grid. Different examples of isolated or nonisolated integrated chargers are reviewed and explained. More
Normally dye molecules are adsorbed onto the nanocrystal (NC) surface in dye-NC mixed solution, but it is very unlikely that all dye molecules present in the solution will be attached to NCs. The distribution of dye molecules on the NC surface is an important factor to take into account while investigating the quenching of NC emission via energy transfer to adsorbed dye molecules. Here, we analyse
