Gas-liquid-solid operation of a Long Draft Tube Self-ingesting Reactor (LDTSR)
2008
Gas-liquid stirred vessels are widely employed to carry out chemical reactions involving a gas reagent and a liquid phase. The usual way for introducing the gas stream into the liquid phase is through suitable distributors placed below the impeller. An interesting alternative is that of using “self ingesting” vessels where the headspace gas phase is injected and dispersed into the vessel through suitable surface vortices. In this work the performance of a Long Draft Tube Self-ingesting Reactor dealing with gas-liquid-solid systems, is investigated. Preliminary experimental results on the effectiveness of this contactor for particle suspension and gas-liquid mass transfer performance in pres…
La internacionalización de las universidades valencianas a través de Twitter
2019
La internacionalización está cobrando gran importancia en las estrategias de comunicación institucional de las universidades españolas. Las redes sociales se revelan como el mejor canal en el construir la marca en busca de estudiantes e investigadores en aras de aumentar su proyección a nivel internacional. Esta investigación analiza el modo en que las cinco universidades públicas de la Comunitat Valenciana aprovechan la comunicación corporativa a través de Twitter para profundizar en sus políticas de internacionalización. El estudio demuestra que las acciones relacionadas con la innovación y la transferencia de conocimientos dominan la comunicación institucional en Twitter de las instituci…
Il packaging come icona culturale? Processi di significazione e meccanismi intertestuali
2020
Questo contributo si interroga sul modo in cui alcune confezioni dei prodotti possano assurgere a icone culturali in grado di condensare, e al tempo stesso trascendere e rilanciare, ampi significati di tipo socioculturale. I packaging di alcuni brand mondiali, gia da tempo, sono diventati non solo segno inconfondibile del brand di appartenenza (si pensi alla contour di Coca-Cola o al barattolo di Nutella), ma anche oggetti in grado di comunicare molto altro, che finiscono per sganciarsi dal marchio e contribuiscono a far circolare valori di consumo, abitudini di un’epoca, usi collettivi di una certa cultura. Attraverso l’analisi di alcuni casi studio, indagheremo proprio quali sono i proces…
Dignità della persona, tutela della vittima e rappresentazioni del processo: amorfismi, imprinting inquisitori, ottativi riformatori
2011
1. Vittima, rito giudiziario e rappresentazioni del processo: tra eredità del passato, istanze partecipative individuali, prospettive empiriche del "non ancora" e insondabilità del vissuto. – 2. Processi e simulacri tra orme del passato e derive del presente: trial by media e popular justice. – 3. Per un itinerario: 'Processo per stupro' (1979) e promozioni socio-culturali di un nuovo "sentire" sulla vittima. – 4. Rituale giudiziario e nuove strategie di produzione dell'evento mediatico. – 5. Trial by media, spettacolo del dolore e consunzione della vittima. – 6. Terapie, volontà riformatrici e nuovi illusionismi: le politiche di autoregolamentazione dei sistemi di produzione mediatica. – 7…
Influence of Viscosity on Mass Transfer Performance of Unbaffled Stirred Vessels
2013
Unbaffled stirred tanks are seldom employed in the process industry as they are considered poorer mixers than baffled vessels. However they may be expected to provide significant advantages in a wide range of applications (e.g. crystallization, food and pharmaceutical processes, etc) where the presence of baffles is often undesirable. Moreover, in plants or animal cell cultivation bioreactors, where cell damage is often caused by bursting bubbles at the air –medium interface (Barret et al., 2010), they can provide sufficient mass transfer through the free surface vortex, so bubble formation and subsequent bursting inside the reactor can be conveniently avoided (Scargiali et al., 2012). In t…
Social Media as Platform for Stimulating Urban Changes
2016
Images have always been an important part of city planning – current images of place, images with planned improvements, maps and sketches. Some time ago all that was a private property of stakeholders like planner and client. But nowadays this confidentiality rather much has vanished – no copyrights or competition is noteworthy. Plans do not have their privacy anymore. They are exposed even before they got implemented. This article will display why city planners share the images of their ideas, of their dreams in public (mostly in blogs and social networks) – why it is important for them and what kind of feedback they are waiting for. This article is based on case study where 12 respondents…
Modelling Quoting in Newswriting : A Framework for Studies on the Production of News
2019
The Mediated Social Communication (MSC) approach considers mass media a venue for opposing and complementary societal groups to publicly negotiate socially relevant topics. This negotiation is conducted through representatives of these groups and mediated by journalists. Inspired by the MSC approach, this paper presents an empirically grounded model that structures the mediating process through the process of quoting. By identifying the key phases of newswriting as sub-processes of quoting, the paper argues that journalists (1) decide on a topical issue to be addressed (topicalisation), (2) identify groups of people who are linked to this issue (societal localisation), (3) pick some people …
Building a political image on Instagram: A study of the personal profile of Santiago Abascal (Vox) in 2018
2020
Due to Instagram’s growing popularity in Spain, politicians have also begun to turn to this social network increasingly more. Accordingly, this paper analyses the visual and textual discourse of 259 posts published throughout 2018 on the personal Instagram profile of Santiago Abascal, the leader of the party Vox. Insofar as he is the Spanish politician with the highest number of followers on Instagram, the aim here is to analyse how he uses this social network in order to identify possible strategies that justify his growing number of followers. In the analysis, special attention was paid to aspects that might have contributed to the (self)presentation of Abascal and the promotion of his pa…
The science case of the FRS Ion Catcher for FAIR Phase-0
2019
The FRS Ion Catcher at GSI enables precision experiments with thermalized projectile and fission fragments. At the same time it serves as a test facility for the Low-Energy Branch of the Super-FRS at FAIR. The FRS Ion Catcher has been commissioned and its performance has been characterized in five experiments with 238U and 124Xe projectile and fission fragments produced at energies in the range from 300 to 1000 MeV/u. High and almost element-independent efficiencies for the thermalization of short-lived nuclides produced at relativistic energies have been obtained. High-accuracy mass measurements of more than 30 projectile and fission fragments have been performed with a multiple-reflection…
Exploration des enjeux de la demande sociale pour les SIC
2016
Les Sciences de l’Information et de la Communication constituent un terrain d’observation privilégié du débat épistémologique opposant la recherche dite fondamentale à la recherche dite appliquée. Cette opposition produit systématiquement un déclassement qualitatif de la seconde au profit de la première. Nous souhaitons ici discuter de la pertinence même du débat ainsi que de ce déclassement qui en est la conséquence. La question est alors double : nos travaux s’inscrivent-il dans la recherche dite « appliquée » ? Sont-ils en cela moins valables scientifiquement que des recherches pouvant apparaître plus nobles car déconnectées d’une valorisation socio-économique ? En complément des élément…
