    Ponència presentada a: Language, Literature, Power (Online Conference), 6-7 May, 2022. Faculty of Philosophy, University of Niš, Serbia.International instruments have long recognized the power of languages and established measures to mitigate and prevent the harm of language deprivation. Indeed, linguistic rights have increasingly been recognized as human rights. In a number of contexts, the effective realization of the most basic linguistic rights depends on the translation from a minority to a dominant language. Legal proceedings are an example, and the European Convention on Human Rights (Article 6) enshrines the right to interpretation and translation for those who do not speak or understand the language of the proceedings. However, monolingual ideologies still loom large on societies, resulting in a number of inadequacies that deprive the speakers of languages socially classified as minor of the necessary resources to enjoy their rights. This contribution will tackle two different contexts, Kosovo, and the Valencian country. Despite the legal obligation to avoid discrimination of speakers of non-dominant languages, judiciary practices discourage and endanger the maintenance and development of the regional and minority languages in both settings. This chapter addresses the lack of maturity of judiciary translation policies focusing on the accuracy, quality, and availability of translation, or lack thereof. In that way, we will show that from translator training to quality standards, societies’ preparedness vis-à-vis their increasing diversity requires improvement

    Critical Pedagogy and Participatory Democracy: Creating Classroom Contexts that Challenge Common Sense. A Response to The Political Nuances of Narratives and an Urban Educator\u27s Response

    In this response to “The Political Nuances of Narratives and an Urban Educator’s Response,” the authors applaud Pearman’s critical approach to deconstructing and challenging narratives of heroic figures who single-handedly change the world and agree with him that these narratives restrict the sense of agency that may propel citizens to become actively involved in social change efforts. We argue that it is important to question why these narratives exist and to understand them in light of the hegemonic capitalist structure that exploits the masses in service to the capitalist class. Although we agree with Pearman that democracy is best served by the participation of every individual in society, we question that common sense coupling of democracy and capitalism and argue that this coupling is integral to the success of the ruling class to maintain the status quo. We find his work of critical importance such that teachers may create classroom contexts that enable students not only to desire to take part in civic responsibilities but also to feel capable of making important contributions that shape society, including challenging the relations of domination across antagonisms: poverty, racism, sexism, heterosexism, et cetera

    4 pages, 3 fiures, 7 tables.-- En: 1st Spanish National Conference on Advances in Materials Recycling and Eco – Energy Madrid, 12-13 November 2009.-- Editors: F. A. López, F. Puertas, F. J. Alguacil and A. Guerrero.FCC is a waste material from petrochemical plants which has interesting properties for preparing binders. FCC is lightly grey in color, and white FCC-portland cements with L*≥85 can be prepared. FCC reactivity is enhanced by grinding and it is attributed to pozzolanic reaction towards lime. Stratlingite is the main hydrated product from pozzolanic reaction, and CSH and CAH are also formed. Reactivity of FCC is high, and low curing temperature does not affect this contribution to strength in hardened mixtures. Additionally, high strength concrete can be easily prepared, and compressive strength greater 100MPa can be reached. Mixtures with low w/b ratio showed good behaviour in carbonation tests.Authors thank to Ministerio de Ciencia y Tecnología of Spain and FEDER the financial support of MAT 2001-2694 and BIA 2004-0052 projects.Peer reviewe

    Study on binary and ternary systems with cement, hydrated lime and fly ash: thermogravimetric analysis, mechanical analysis and durability behaviour

    Get PDF
    The use of high percentages of substitution of Portland cement by pozzolans can provoke the total consumption of portlandite. The present research proposes the study of ternary systems of Portland cement (PC), fly ash (FA), and hydrated lime (CH). After 180 days of curing, the mortar with 50% substitution of PC by FA obtained 65.9 MPa versus the mortars with an addition of 20% of CH and control mortar (100 PC) that obtained 69.9 MPa and 76.7 MPa respectively: this behavior is very positive value considering that tested FA containing mortars had a 50% of Portland cement. Regarding the effect of the amount of extra hydrated lime on durability issues, the evolution against carbonation of PC-FA and PC-CH-FA mortars was studied: the reduction of carbonation velocity was around a 37% for the mortar with CH respect the PC-FA mortar

    "This document is the Accepted Manuscript version of a Published Work that appeared in final form in ACS Sustainable Chemistry & Engineering, copyright © American Chemical Society after peer review and technical editing by the publisher. To access the final edited and published work see http://pubs.acs.org/doi/abs/10.1021%2Facssuschemeng.6b00770.”Biomass has gained in importance as an energy source in recent years. One of the crops that presents interesting opportunities with regard to biomass is sugar cane. In Brazil, sugar cane production is increasing for alcohol and sugar manufacture. Some by-products, such as sugar cane straw, also are obtained during harvesting. Due the calorific value of the sugar cane straw, its use as biomass is increasing. After the straw is burned to produce energy, an ash is obtained: sugar cane straw ash (SCSA). This waste needs an appropriate destination and, since the recent publication of successful studies using biomass derived-ashes as pozzolanic material, the present study aimed to assess the pozzolanic reactivity of sugar cane straw ash. The pozzolanic activity was assessed using a new and simple recently proposed method: evaluation of the electrical conductivity of calcium hydroxide (CH) and pozzolan suspensions, in which solid CH is initially present. These results were compared to those of two other well-established techniques: Fourier transformed infrared spectroscopy and thermogravimetric analysis. The evaluation by all three techniques is similar and shows that sugar cane straw ash is a good pozzolanic material: high lime fixation values for CH:SCSA mixes were determined by thermogravimetric analysis and unsaturation respect to CH in 3.5:6.5 CH:SCSA suspension was achieved at 60ºC. According to this behaviour, a bright future for SCSA as a replacement for Portland cement is expected.We thank CNPq (processo no. 401724/2013-1) and the "Ministerio de Education, Cultura y Deporte" of Spain ("Cooperacion Interuniversitaria" program with Brazil PHB-2011-0016-PC).

    El estudio del comportamiento mecánico de elementos prefabricados de concreto producidos con base en residuos agroindustriales es un tema clave para optimizar y potenciar el uso de estos residuos en la industria de la construcción. En este trabajo se estudió la influencia del mezclado en dos etapas sobre la resistencia a la compresión de ladrillos de concreto elaborados con ceniza de cascarilla de arroz (CCA) proveniente de la arrocera la Esmeralda ubicada en Cali-Valle (Colombia). Este residuo se incorporó en mezclas de concreto con el fin de estudiar su efecto como puzolana en la sustitución parcial de cemento y como filler en la sustitución del agregado fino para la fabricación de ladrillos de concreto. Los resultados obtenidos mostraron que la adición del 20% de CCA actuando como filler y puzolana es la composición óptima para el uso de este residuo agro-industrial en la fabricación de bloques. Además se encontró que el proceso de mezclado en dos etapas mejora la calidad del prefabricado, aumentando las propiedades mecánicas de las mezclas elaboradas a 28 días de curado.Mattey, PE.; Robayo, R.; Díaz, JE.; Delvasto Arjona, S.; Monzó Balbuena, JM.

A definitive version was subsequently published in Nuclear Instruments and Methods in Physics Research Section A, Volume 702, 21 February 2013, Pages 94–97 DOI 10.1016/j.nima.2012.08.028In this paper we describe the overall design of a PET–MR system for head imaging within the framework of the DREAM Project as well as the first detector module tests. The PET system design consists of 4 rings of 16 detector modules each and it is expected to be integrated in a head dedicated radio frequency coil of an MR scanner. The PET modules are based on monolithic LYSO crystals coupled by means of optical devices to an array of 256 Silicon Photomultipliers. These types of crystals allow to preserve the scintillation light distribution and, thus, to recover the exact photon impact position with the proper characterization of such a distribution. Every module contains 4 Application Specific Integrated Circuits (ASICs) which return detailed information of several light statistical momenta. The preliminary tests carried out on this design and controlled by means of ASICs have shown promising results towards the suitability of hybrid PET–MR systems.This work was supported by the Centre for Industrial Technological Development co-funded by FEDER through the Technology Fund (DREAM Project, IDI-20110718), the Spanish Plan Nacional de Investigacion Cientifica, Desarrollo e Innovacion Tecnologica (I + D + I) under Grant no.

    NEXT-100 Technical Design Report (TDR). Executive Summary

    Get PDF
    In this Technical Design Report (TDR) we describe the NEXT-100 detector that will search for neutrinoless double beta decay (bbonu) in Xe-136 at the Laboratorio Subterraneo de Canfranc (LSC), in Spain. The document formalizes the design presented in our Conceptual Design Report (CDR): an electroluminescence time projection chamber, with separate readout planes for calorimetry and tracking, located, respectively, behind cathode and anode. The detector is designed to hold a maximum of about 150 kg of xenon at 15 bar, or 100 kg at 10 bar. This option builds in the capability to increase the total isotope mass by 50% while keeping the operating pressure at a manageable level. The readout plane performing the energy measurement is composed of Hamamatsu R11410-10 photomultipliers, specially designed for operation in low-background, xenon-based detectors. Each individual PMT will be isolated from the gas by an individual, pressure resistant enclosure and will be coupled to the sensitive volume through a sapphire window. The tracking plane consists in an array of Hamamatsu S10362-11-050P MPPCs used as tracking pixels. They will be arranged in square boards holding 64 sensors (8 times8) with a 1-cm pitch. The inner walls of the TPC, the sapphire windows and the boards holding the MPPCs will be coated with tetraphenyl butadiene (TPB), a wavelength shifter, to improve the light collection.Comment: 32 pages, 22 figures, 5 table
