‘Stars’ or ‘professionals’: the imagined vocation and exclusive knowledge of translators in Israel
2010
Amb l’examen de la professionalització suspesa de l’ocupació traductora a Israel, aquest article estudia dos tipus de discursos d’autopresentació i estratègies d’estatus: d’una banda, els dels traductors literaris, i de l’altra, els dels traductors tècnics, subtituladors i traductors literaris que no pertanyen a l’elit. L’anàlisi del primer grup es fonamenta en diversos centenars d’articles retrat i altres reportatges en els mitjans de comunicació, que situen en primer pla 23 traductors reconeguts, mentre que la del segon grup es basa en resultats provisionals d’entrevistes obertes amb 22 treballadors de la traducció no pertanyents a l’elit (seleccionats a partir d’una mostra més àmplia reu…
MELISSA: Laser ion source setup at CERN-MEDICIS facility. Blueprint
2019
The Resonance Ionization Laser Ion Source (RILIS) has become an essential feature of many radioactive ion beam facilities worldwide since it offers an unmatched combination of efficiency and selectivity in the production of ion beams of many different chemical elements. In 2019, the laser ion source setup MELISSA is going to be established at the CERN-MEDICIS facility, based on the experience of the workgroup LARISSA of the University Mainz and CERN ISOLDE RILIS team. The purpose is to enhance the capability of the radioactive ion beam supply for end users by optimizing the yield and the purity of the final product. In this article, the blueprint of the laser ion source, as well as the key …
Application and development of ion-source technology for radiation-effects testing of electronics
2017
Abstract Studies of heavy-ion induced single event effect (SEE) on space electronics are necessary to verify the operation of the components in the harsh radiation environment. These studies are conducted by using high-energy heavy-ion beams to simulate the radiation effects in space. The ion beams are accelerated as so-called ion cocktails, containing several ion beam species with similar mass-to-charge ratio, covering a wide range of linear energy transfer (LET) values also present in space. The use of cocktails enables fast switching between beam species during testing. Production of these high-energy ion cocktails poses challenging requirements to the ion sources because in most laborat…
CERN’s Linac4 cesiated surface H− source
2017
Linac4 cesiated surface H− sources are routinely operated for the commissioning of the CERN’s Linac4 and on an ion source test stand. Stable current of 40-50 mA are achieved but the transmission through the LEBT of 80% was below expectations and triggered additional beam simulation and characterization. The H− beam profile is not Gaussian and emittance measurements are larger than simulation. The status of ongoing development work is described; 36 mA H− and 20 mA D− beams were produced with a 5.5 mm aperture cesiated surface ion source. The emittances measured at the test stand are presented. During a preliminary test, the Linac4 proton source delivered a total beam intensity of 70 mA (p, H…
Recent Advances in On-Line Laser Spectroscopy
2015
At radioactive ion beam facilities, particle accelerators are employed to induce nuclear reactions in order to provide short-lived nuclei for immediate study using a variety of spectroscopic techniques. These exotic isotopes/isomers are formed into a beam of fast ions, which are mass analyzed in-flight during transport to a chosen experimental set-up. As an additional filter, the atomic level structure provides a selective fingerprint, which distinguishes one element from another due to the varying numbers of protons and electrons. This property is exploited in laser ion sources whereby high power, pulsed tuneable laser radiation is used to excite and ionize the atom in order to enhance the…
The Assessment of Professionalism for Ambulance Personnel – Problems and Challenges
2015
The purpose of this paper is to clarify whether annual knowledge testing at a work place promotes Ambulance professionals for personnel development, and if it providesthe possibility to assess personnel’s competence and professionalism. The results of 1693 ambulance personnel’s annual knowledge testing in years 2011, 2012,2013 are analysed in the research. The results obtainedreflect that in all stages knowledge improves, but there are not possibility to assess personnel’s competence and professionalism for building personnel development programs in the future.
Macrofungi as ecosystem resources: Conservation versus exploitation
2013
Fungi are organisms of significant importance not only for the crucial roles they undertake in nature but also for many human activities that are strictly dependent on them. Indeed, fungi possess fundamental positions in ecosystems functioning including nutrient cycles and wood decomposition. As concerns human-related activities, edible and non-edible mushrooms are also involved and/or exploited in forestry, pharmaceutical industry and food production; hence, nowadays they represent a major economic source worldwide. In order to maintain and improve their strategic importance, several conservation strategies, such as habitat preservation, are needed. This article reports several contributio…
Territorial and socio-economic organisation in Le Grand-Pressigny
2012
In and around Le Grand-Pressigny (Indre-et-Loire, France), a petrographic study was implementedon 92 ceramic samples from the Final Neolithic sites of Le Petit-Paulmy and Bergeresse (Abilly).Analyses showed that the sediments used were extracted from local sources: Claise and Creusealluvium, local substrate and loessic silts. Quantitatively, the study showed that almost all the ceramicmaterials in Bergeresse and more than half of those in Le Petit-Paulmy come from the valley of theCreuse. The mineralogical compositions of three samples from Le Petit-Paulmy, including one ofunusual form, indicate sources from an exogenous region, the Massif Central (perhaps the alluviumof the Loire or the Al…
Au cœur de la terminologie du jeu vidéo. L’absence de ressources, frein majeur pour les traducteurs

Sustainable Method Using Filtering Techniques for a Fermentation Process State Estimation
2020
Winemaking is concerned about sustainable energy availability that implies new methods for process monitoring and control. The aim of this paper is to realize a comparative analysis of the possibilities offered using estimation techniques, balances, and filtering techniques such as the Kalman filter (KF) and the extended Kalman filter (EKF), to obtain indirect information about the alcoholic fermentation process during winemaking. Thus, an estimation solution of the process variables in the exponential growing phase is proposed, using an extended observer. In addition, two estimation solutions of this process with the EKF and an estimation of the decay phase of the fermentation process are …
