Particle transport in recirculated liquid metal flows
2008
PurposeAims to present recent activities in numerical modeling of turbulent transport processes in induction crucible furnace.Design/methodology/approach3D large eddy simulation (LES) method was applied for fluid flow modeling in a cylindrical container and transport of 30,000 particles was investigated with Lagrangian approach.FindingsParticle accumulation near the side crucible boundary is determined mainly by the ρp/ρ ratio and according to the presented results. Particle settling velocity is of the same order as characteristic melt flow velocity. Particle concentration homogenization time depends on the internal flow regime. Separate particle tracks introduce very intensive mass exchang…
La mesura de l'ús de les llengües en els mitjans telemàtics
2020
La consolidació de l'entorn digital i totes les seues modalitats de comunicació ha ampliat les possibilitats d'interacció i, per tant, els àmbits d'ús de les llengües. Com a adaptació a aquesta nova realitat, en aquesta aproximació metodològica plantegem la combinació de diferents tècniques no reactives: explotació de fonts secundàries, observació sistemàtica, i mystery shopping. Les fonts d'observació directa ens permeten mesurar de manera efectiva l'ús de les llengües en la comunicació telemàtica. Els autors ho han aplicat específicament en l'administració local i en empreses de serveis. En l'àmbit administratiu, a més, això ens ha servit per a desenvolupar un índex global de presència de…

CD38 expression enhances sensitivity of lymphoma T and B cell lines to biochemical and receptor-mediated apoptosis
2006
CD38 has been widely characterised both as an ectoenzyme and as a receptor. In the present paper, we investigated the role of CD38 as possible modulator of apoptosis. CD38-positive (CD38(+)) and negative (CD38(-)) fractions, obtained by sorting CD38(+) cells from lymphoma T (Jurkat) and lymphoma B (Raji) and by transfecting lymphoma LG14 and myeloid leukemia K562 cell lines, were used. Cellular subpopulations were exposed to different triggers (H(2)O(2), UV-B, alpha-TOS and hrTRAIL) and the extent of apoptosis was determined by Annexin V-FITC/PI assay. Our data showed that, in lymphoma cells, propensity to apoptosis was significantly linked to CD38 expression and that, remarkably, such resp…
New analysis of ηπ tensor resonances measured at the COMPASS experiment
2018
We present a new amplitude analysis of the $\eta\pi$ $D$-wave in $\pi^- p\to \eta\pi^- p$ measured by COMPASS. Employing an analytical model based on the principles of the relativistic $S$-matrix, we find two resonances that can be identified with the $a_2(1320)$ and the excited $a_2^\prime(1700)$, and perform a comprehensive analysis of their pole positions. For the mass and width of the $a_2$ we find $M=(1307 \pm 1 \pm 6)$~MeV and $\Gamma=(112 \pm 1 \pm 8)$~MeV, and for the excited state $a_2^\prime$ we obtain $M=(1720 \pm 10 \pm 60)$~MeV and $\Gamma=(280\pm 10 \pm 70)$~MeV, respectively.
Riddere på slakk line : Om pårørende, uhelbredelig kreft og komplementær og alternativ behandling
2014
Masteroppgave Universitetet i Agder, 2014 Fakultet for helse- og idrettsvitenskap Institutt for helse- og sykepleievitenskap Forskning viser at KAM-bruk er utbredt blant kreftpasienter, og pasienter med uhelbredelig kreft oppsøker i større grad KAM-behandlere. Pårørende er sentral i støtte og omsorg for pasienten, og opplever byrder og belastning i denne rollen. Hensikten med denne masteroppgaven har vært å bidra til økt kunnskap om pårørendes opplevelser, for videre kunne gi dem bedre støtte og hjelp. Problemstillingen i dette prosjektet lyder: Hvordan oppleves det å være pårørende til personer med uhelbredelig kreft som søker komplementær og alternativ behandling? Empiriske data er hentet…

National fiscal consolidations and regional inequality in Europe
2016
Using annual data for 13 European countries over the period 1980-2008, we assess the impact of national fiscal consolidations on the income inequality of European regions. Regional dispersion increases in the outcome of consolidation episodes, particularly, when packages are more severe and implemented through spending cuts rather than tax rises. From a policy perspective, these findings suggest that fiscal consolidations driven by reductions in government spending can exacerbate regional disparities and may ultimately counteract the European policy efforts to promote territorial cohesion. Our results are robust to alternative inequality measures, the occurrence of crisis episodes and the e…
Searching for Threshold Effects in the Evolution of Budget Deficits: An Application to the Spanish Case
2004
Abstract In this paper, we use recent developments on threshold autoregressive (TAR) models that allow us to derive endogenously threshold effects in the evolution of the Spanish budget deficit. Specifically, a mean-reverting dynamic behaviour of the budget deficit should be expected once such threshold is reached.
Assessing long-term fiscal developments : a new approach
2011
We use a new approach to assess long-term fiscal developments. By analyzing the time-varying behaviour of the two components of government spending and revenue – responsiveness and persistence–, a feature not captured by automatic stabilisers, we are able to infer about the sources of fiscal deterioration (improvement). Drawing on quarterly data, we estimate recursively these components within a system of government revenue and spending equations using a Three-Stage Least Square method for eight European Union countries plus the US. The results suggest that significant changes in the fiscal stance (including those related to the current crisis) are reflected in the estimates of persistence …
