The Fluorescence Detector of the Pierre Auger Observatory

2010

The Pierre Auger Observatory is a hybrid detector for ultra-high energy cosmic rays. It combines a surface array to measure secondary particles at ground level together with a fluorescence detector to measure the development of air showers in the atmosphere above the array. The fluorescence detector comprises 24 large telescopes specialized for measuring the nitrogen fluorescence caused by charged particles of cosmic ray air showers. In this paper we describe the components of the fluorescence detector including its optical system, the design of the camera, the electronics, and the systems for relative and absolute calibration. We also discuss the operation and the monitoring of the detecto…

Arabidopsis copper transport protein COPT2 participates in the crosstalk between iron deficiency responses and low phosphate signaling

2013

[EN] Copper and iron are essential micronutrients for most living organisms because they participate as cofactors in biological processes, including respiration, photosynthesis, and oxidative stress protection. In many eukaryotic organisms, including yeast (Saccharomyces cerevisiae) and mammals, copper and iron homeostases are highly interconnected; yet, such interdependence is not well established in higher plants. Here, we propose that COPT2, a high-affinity copper transport protein, functions under copper and iron deficiencies in Arabidopsis (Arabidopsis thaliana). COPT2 is a plasma membrane protein that functions in copper acquisition and distribution. Characterization of the COPT2 expr…

On the Conceptual History of the Term Lingua Franca

2015

This paper aims to give an outline of the development of the term “Lingua Franca”. Initially the proper name of an extinct pidgin, to “Lingua Franca”, the term has become a common noun, used with regard to language contact phenomena in general – at first specifically for pidgins and trade languages, but now for all vehicular languages. This broader usage is especially prominent in the field of research known as “English as a lingua franca” (ELF). Using ELF as an example, it is shown that the modern usage is partly inconsistent and can be misleading, as it connects a positive feature of the original Lingua Franca, viz linguistic equality, with a language with native speakers like English, wh…

Bilingvālā izglītība pirmsskolā 3-4gadīgu bērnu latviešu kā otrās valodas apguves veicināšanai

2022

Darba autore Iluta Pudule. Darba tēma “Bilingvālā izglītība pirmsskolā 3-4 gadīgu bērnu latviešu kā otrās valodas apguves veicināšanai”. Pētījuma mērķis - izpētīt bilingvālās izglītības pirmsskolās 3-4 gadīgu bērnu latviešu kā otrās valodas apguves veicināšanu. Kvalifikācijas darba uzdevumi: 1.analizēt zinātnisko literatūru par valodas apgūšanu un divvalodību; 2.izpētīt un raksturot 3-4 gadīgu bērnu attīstību un otrās valodas apguves īpatnības; 3.veikt anketēšanu un analizēt datus par latviešu valodas apguvi bilingvālā mācību procesā pirmsskolā. Pētījuma gaitā gūtie rezultāti ļauj secināt, ka divvalodība bērna pašizgaugsmei, pilnvērtīgai, un vispusīgai attīstībai netraucē. Pētījuma daļā tik…

Dentro il conflitto

2017

Argomentare sulle opere di Fabrizio Ciappina delinea per chi scrive due superamenti: da una parte, la necessità di affrancarsi dalla consuetudine dei rapporti con l’autore che, seppur smorzata dagli affastellamenti della vita, finirebbe per ridurre, oltremodo, la giusta distanza dalla quale osservarle; dall’altra, l’esigenza di riordinare nella memoria i soggetti rappresentati. Essi, infatti, interpretando luoghi noti per aderenza anagrafica, sfocano le immagini impresse nel ricordo disegnando un'inedita convivenza tra realtà remota e simulacro. Emerge una rappresentazione fantastica collocata in una temporalità indistinta, eppure terrena. Essa si sovrappone ai rimandi iconografici di un lu…

Carga y factores de riesgo para la neumonía adquirida en la comunidad de Pseudomonas aeruginosa : un estudio multinacional de prevalencia puntual de …

2018

Pseudomonas aeruginosa is a challenging bacterium to treat due to its intrinsic resistance to the antibiotics used most frequently in patients with community-acquired pneumonia (CAP). Data about the global burden and risk factors associated with P. aeruginosa-CAP are limited. We assessed the multinational burden and specific risk factors associated with P. aeruginosa-CAP. We enrolled 3193 patients in 54 countries with confirmed diagnosis of CAP who underwent microbiological testing at admission. Prevalence was calculated according to the identification of P. aeruginosa. Logistic regression analysis was used to identify risk factors for antibiotic-susceptible and antibiotic-resistant P. aeru…

Key Issues Relevant to the Studies to Be Reported: Beliefs, Agency and Identity

2016

As pointed out in Chapter 1, this volume is a response to the recent calls for research on learner and teacher beliefs that would be not only contextual and longitudinal, but also interconnected. In other words, beliefs should be viewed in relation to other issues that play a role in learning and teaching foreign languages. These include aspects of those involved in the processes of learning and teaching foreign languages, that is, learners and teachers — their agency and identity, for example. This chapter provides background to the seven studies that will be reported later in Chapters 3–9 by reviewing the key issues addressed: beliefs, agency and identity. In the following, an attempt wil…

Analyse des acquisitions des élèves de l'enseignement secondaire en Algérie sur la base de l'enquête MLA II

2006

06020; Rapport pour la Revue des dépenses publiques en République Algérienne et Populaire, réalisée par le Groupe pour le Développement socioéconomique. Région Moyen Orient et Afrique du Nord de la Banque Mondiale; Le rapport est basé sur l'analyse des résultats des élèves de 8ème année de l'enseignement secondaire en Algérie aux tests du MLAII (tests administrés en 2002). L'analyse présentée ici est de nature synthétique et cherche avant tout à dégager les facteurs principaux agissant sur les acquis des élèves. Il ne s'agit donc pas d'effectuer une description fine des acquis scolaires dans une optique pédagogique, mais plutôt de mettre en relation un certain nombre de variables centrales …
