Atkārtojums Semjuela Beketa dramaturģiskajā darbā “Luga”
2016
Semjuela Beketa dramatiskais darbs “Luga” ir gan netradicionāls, gan unikāls. Luga uzrakstīta 1963.gadā un atšķiras no citiem darbiem ar bezemocionāliem un neizteiksmīgiem personāžiem. Uz skatuves atrodas trīs personāži, kuri nespēj ne kustēties, ne runāt izteiksmīgi, ne paust emocijas, ne izmantot mīmiku. Lai izprastu šo lugu, jāizpēta tas, kas jau dots – mākslinieciskie izteiksmes līdzekļi. Atkārtojums ir viens no visvairāk izmantotajiem līdzekļiem un katrs personāžs to izmanto citādāk, lai panāktu noteiktu efektu uz klausītāju. Katrs atkārtojums var tikt grupēts atšķirīgās kategorijās un katram no tiem ir sava funkcija dramatiskajā darbā. Visbiežāk atkārtojums izmantots, lai pabeigtu dom…
Networking Healthcare from a competitive call to a medical cooperation as a guarantee of a found confidence
2012
Le reseau en sante : de la mise en concurrence a la cooperation des soignants comme garantie d‘une confiance retrouveeL’objectif de cet article consiste a situer le reseau de sante entre la concurrence et la cooperation selon l’acceptation qui en est faite, et de repenser en consequence les relations entre les prestataires de soins ainsi que le pilotage de ces formes organisationnelles innovantes dans le systeme de sante francais. Nous proposons en premier lieu, une etude synthetique des resultats theoriques, puis sur les effets observes dans les differents pays concernes (anglo-saxons puis europeens), de l’introduction de mecanismes concurrentiels visant a reguler plus efficacement le syst…
The Importance of Empowerment in Entrepreneurship
2017
Empowerment comes at a time when global competition and change require people to take initiative and be innovative. Based on the active, persistent, and change-oriented behaviors associated with psychological empowerment, the chapter states that empowerment can contribute to entrepreneurship. The dimensions of empowerment that suggest a theoretical and empirical link with entrepreneurial behavior are discussed. Several propositions regarding the interplay between empowerment and entrepreneurship are formulated. The chapter describes paths to promote empowerment and entrepreneurship in applied context and suggests future directions to advance research on empowerment in the field of entrepren…

Partitioning of nitrogen during melting and recycling in subduction zones and the evolution of atmospheric nitrogen
2019
Abstract The subduction of sediment connects the surface nitrogen cycle to that of the deep Earth. To understand the evolution of nitrogen in the atmosphere, the behavior of nitrogen during the subduction and melting of subducted sediments has to be estimated. This study presents high-pressure experimental measurements of the partitioning of nitrogen during the melting of sediments at sub-arc depths. For quantitative analysis of nitrogen in minerals and glasses, we calibrated the electron probe micro-analyzer on synthetic ammonium feldspar to measure nitrogen concentrations as low as 500 μg g−1. Nitrogen abundances in melt and mica are used together with mass balance calculations to determi…
SVM-based classification of High resolution Urban Satellites Images using Dense SURF and Spectral Information
2018
Remote-sensing focusing on image classification knows a large progress and receives the attention of the remote-sensing community day by day. Combining many kinds of extracted features has been successfully applied to High resolution urban satellite images using support vector machine (SVM). In this paper, we present a methodology that is promoting a performed classification by using pixel-wise SURF description features combined with spectral information in Cielab space for the first time on common scenes of urban imagery. The proposed method gives a promising classification accuracy when compared with the two types of features used separately.
Lower mantle hydrogen partitioning between periclase and perovskite : a quantum chemical modelling
2016
Abstract Partitioning of hydrogen (often referred to as H2O) between periclase (pe) and perovskite (pvk) at lower mantle conditions (24–80 GPa) was investigated using quantum mechanics, equilibrium reaction thermodynamics and by monitoring two H-incorporation models. One of these (MSWV) was based on replacements provided by Mg2+ ↔ 2H+ and Si4+ ↔ 4H+; while the other (MSWA) relied upon substitutions in 2Mg2+ ↔ Al3+ + H+ and Si4+ ↔ Al3+ + H+. H2O partitioning in these phases was considered in the light of homogeneous (Bulk Silicate Earth; pvk: 75%–pe:16% model contents) and heterogeneous (Layered Mantle; pvk:78%–pe:14% modal contents) mantle geochemical models, which were configured for lower…
ASSESSING TRACE ELEMENT (DIS)EQUILIBRIUM AND THE APPLICATION OF SINGLE ELEMENT THERMOMETERS IN METAMORPHIC ROCKS
2018
Abstract Empirical and experimental calibration of single element solubility thermometers, such as Zr-in-rutile, Zr-in-titanite, Ti-in-zircon, and Ti-in-quartz, within the past 13 years has greatly expanded our ability to assess the pressure and temperature conditions of individual minerals associated with specific textures in metamorphic rocks. Combined with advances in in situ techniques for analyzing trace concentrations, this has led to an increase in the combined use of single element thermometers, geochronometers, and isotope ratios, often simultaneously, in metamorphic minerals. Here we review the calibration and application of single element thermometers at the pressure and temperat…
Chlorine Partitioning Between a Basaltic Melt and H2O-CO2 Fluids at Mount Etna
2009
Partitioning experiments between a basaltic melt from Mt. Etna and a low-density hydrous fluid or vapor containing H(2)O or H(2)O-CO(2) were performed at 1200-1260 degrees C, at pressures between 1 and 200 MPa, either near the nickel-nickel oxide (NNO) buffer or at two log units above it (NNO + 2), and with different chloride concentrations. Most of the experiments were done at chloride-brine-undersaturated conditions, although at the highest Cl concentrations explored brine saturation might have been reached. The average partition coefficients (D(Cl)(fluid/melt)) over the range of Cl concentrations were derived on a weight basis by plotting the calculated concentrations of Cl in the fluid …
ESR/U-series chronology of early Neanderthal occupations at Cova Negra (Valencia, Spain)
2019
Abstract The spatiotemporal repartition of Neanderthal populations throughout the late Middle and early Upper Pleistocene is of great interest for our understanding of human evolution. Establishing a reliable chronology for human-bearing layers from prehistoric sites is thus essential for the study of Neanderthal population dynamics prior to modern human arrival in Europe. Cova Negra (Valencia, Spain) is one of the richest sites documenting Neanderthal fossil bones in the Iberian Peninsula (Arsuaga et al., 1989, 2007; Villaverde et al., 2014). The stratigraphic sequence includes 15 Middle Palaeolithic layers. Among them, four were dated by the ESR/U-series dating method on enamel from six h…
