Toward Sustainable PLA-Based Multilayer Complexes with Improved Barrier Properties

2019

Poly(lactic acid) or PLA is currently considered as one of the most promising substitutes of conventional plastics, with low environmental impact, especially for food packaging applications. Nevertheless, some drawbacks, such as high permeability to oxygen, are still limiting its industrial applications. The objective of this study was to highly increase the oxygen barrier performance of PLA without compromising its sustainable nature and following the principles of circular economy perspective. Coproducts coming from mill industries, such as wheat gluten proteins (WG), were used to produce PLA-WG-PLA multilayer complexes with improved barrier performance. Different technologies of industri…

Risk narrations and perceptions in the COVID-19 time. A discourse analysis through the Italian press

2020

This paper explores how the risk related to the pandemic of COVID-19 was managed, narrated and perceived in Italy during the lockdown phase, from February until June 2020. To reach this aim, the study provides a discourse analysis of three main level: the official institutional discourses declaimed by the government and the health authority; the risk narration spread through the diaphragm of the Italian press, and specifically through two of the most-read newspapers in Italy (Repubblica and Corriere della Sera) and their related weeklies (Venerdì di Repubblica and Sette); finally, the diverse reactions and perceptions to the risk coming from the most affected and most vulnerable subjects, c…

Agenda and media pluralism in Al Rojo Vivo and Las Mañanas de Cuatro

2019

En: Doxa Comunicación: revista interdisciplinar de estudios de comunicación y ciencias sociales. e-ISSN 2386-3978 n. 29, 2019, pp 113-137. Aun con el auge del entorno digital e híbrido, la televisión continúa siendo el principal medio de información en España. Se toma una muestra de 50 programas (25 de “Al Rojo Vivo” y 25 de “Las Mañanas de Cuatro”) para registrar quién participa en ellos, en qué condiciones lo hacen y sobre qué temas se discute. Se aprecia un alto grado de equivalencia en la agenda establecida y una bajísima inclusión de mujeres. El Procés catalán monopolizó la atención. La metodología incluye la cuantificación de los contraargumentos recibidos por los contertulios, mostra…

Legiones y Falanges: prensa populista y literatura

2020

Addressing people in order to enforce their power is a common feature of different political parties and governments, regardless of whether they are right wing or left wing, and, in this process, the press plays a crucial role. In this context, the bilingual publication Legioni e Falangi. Rivista d’Italia e di Spagna/Legiones y Falanges. Revista mensual de Italia y de España (1940–43) is a paradigmatic example. Some of the most important intellectuals of the time, including Azorín, Manuel Machado and Gerardo Diego, wrote in this magazine, facing historical reality of Fascism and Francoism and generating unexpected results. Hoy en día la relación osmótica entre populismo y medios de comunica…

«Sykt lykkelig på sosiale medier» : ungdom og sosiale medier i det postmoderne samfunn : hvordan bruker – og fremstiller dagens ungdom seg på sosiale…

2019

Masteroppgave samfunnskunnskap SV505 - Universitetet i Agder 2019 Denne oppgaven omhandler ungdoms bruk av og fremstilling av seg selv på sosiale medier i lys av samtiden, det postmoderne samfunn. Oppgaven tar for seg hvilke medier ungdom bruker, hvordan og hvorfordebruker sosiale medier, samt hvor mye tid de bruker på sosiale medier. Også hvordan unge presenterer og fremstiller seg selv i ulike sosiale medier blir undersøkt. Med utgangpunkt i den såkalte«Generasjon prestasjon» vies ungdoms opplevelse av press og stress på sosiale medier ekstra oppmerksomhet.Oppgaven baserer seg på en empirisk –kvantitativ spørreundersøkelse av til sammen 148 ungdommer i ungdomsskolen og på videregående sko…

La forja de la posverdad en el discurso nacional-sindicalista: «Y» (1938-1945)

2018

In «Y» (1938-1945), the Women’s Section aims to contribute to the implementation of the values of Francoism, influencing the ideas and behaviour of Spanish women through the creation of a post-truth, which legitimizes and ensures the survival of power elites. In this paper, adopting the theoretical perspective of argumentative-persuasive discourse analysis, I will demonstrate how the national- syndicalist discourse creates its post-truth, through some “extra dictione” fallacies, based essentially on two macro-strategies: the negation of reality, and equally, the construction of a positive reality. En «Y» (1938-1945), la Sección femenina pretende coadyuvar la afirmación de los valores del fr…

Influence of the process parameters on the microstructure of a hardfacing coating elaborated by hot isostatic pressing

2019

Hot Isostatic Pressing elaboration of Norem02, an austenitic-ferritic hypereutectoid stainless steel, leads to the formation ofan austenitic matrix with a mixture of acicular M7C 3 and globular M23 C 6 carbides. The sintering tests, carried out by using an AISI304L container, showed that the final microstructure and the carbides’ distribution of the HIPed Norem02 are strongly influencedby the process parameters (heating and cooling rate, sintering time, holding temperature and pressure) and by the particles’ size,microstructure and phase distribution of the initial powder. The morphological, crystallographic and chemical analysis of the sinteredsamples were completed by comprehension of the…

New high-pressure phase and equation of state of Ce2Zr2O8

2012

In this paper we report a new high-pressure rhombohedral phase of Ce2Zr2O8 observed from high-pressure angle-dispersive x-ray diffraction and Raman spectroscopy studies up to nearly 12 GPa. The ambient-pressure cubic phase of Ce2Zr2O8 transforms to a rhombohedral structure beyond 5 GPa with a feeble distortion in the lattice. Pressure evolution of unit-cell volume showed a change in compressibility above 5 GPa. The unit-cell parameters of the high-pressure rhombohedral phase at 12.1 GPa are ah = 14.6791(3) {\AA}, ch = 17.9421(5) {\AA}, V = 3348.1(1) {\AA}3. The structure relation between the parent cubic (P2_13) and rhombohedral (P3_2) phases were obtained by group-subgroup relations. All t…

Diversidad latina y comunicación panhispana en la prensa en español de Nueva York al inicio del siglo XXI

2008

En: Doxa Comunicación : revista interdisciplinar de estudios de comunicación y ciencias sociales. ISSN 1696-019X n. VI, 2008, pp 15-51 Las transformaciones de la prensa hispana en Nueva York en la década del cambio de siglo apuntan la configuración de una incipiente identidad cultural panhispánica. Esa identidad panhispánica se muestra gracias al contenido informativo y publicitario de diversos periódicos en español de esa ciudad, pero sobre todo mediante los tres diarios El Diario-La Prensa, Hoy y Noticias del Mundo. La metodología empleada ha sido un análisis cuantitativo-cualitativo de sus contenidos informativos y publicitarios, con el objetivo de evaluar el carácter de esa prensa, adem…
