Vortex shape in unbaffled stirred vessels: experimental study via digital image analysis
2011
There is a growing interest in using unbaffled stirred tanks for addressing certain processing needs. In this work, digital image analysis coupled with a suitable shadowgraphy-based technique is used to investigate the shape of the free-surface vortex that forms in uncovered unbaffled stirred tanks. The technique is based on back-lighting the vessel and suitably averaging vortex shape over time. Impeller clearance from vessel bottom and tank filling level are varied to investigate their influence on vortex shape. A correlation is finally proposed to fully describe vortex shape also when the vortex encompasses the impeller.
Claudio Guillén en Harvard, génesis del comparatismo español
2020
En el presente trabajo se reconstruye el paso de Claudio Guillén por la Universidad de Harvard, donde se formó como comparatista junto a varios de los mejores estudiosos del momento, y donde ejerció como profesor durante sus últimos años en Estados Unidos. Esta revisión de la trayectoria profesional y personal de Claudio Guillén ayuda a entender la evolución de la disciplina de la Literatura Comparada en la Universidad de Harvard dentro del marco del comparatismo norteamericano de postguerra, los estudios literarios del propio Claudio Guillén y su esfuerzo por impulsar la disciplina de la Literatura Comparada en España, así como la particular circunstancia social de los intelectuales españo…
A Territorial Approach to the Production of Urban and Rural Landscape.
2018
The authors, starting from the examination of the historic data of Palermo landscapes on the south-east side, draws up an analysis of the landscape by illustrating the environmental characteristics and the intervention of man in its transformations. Therefore, determined by a certain point to refer to, the author, on the basis of archival, literary, and existing graphic documentation, has therefore sought to illustrate the evolution of the landscape in the geographical area of Maredolce while still presenting relations with the territory of Palermo. Examining the diaries at the end of the eighteenth century with the help of the water colored planks of the sites taking into account the great…
Cell therapy medicinal product regulatory framework in Europe and its application for MSC-based therapy development
2012
Advanced therapy medicinal products (ATMPs), including cell therapy products, form a new class of medicines in the European Union. Since the ATMPs are at the forefront of scientific innovation in medicine, specific regulatory framework has been developed for these medicines and implemented from 2009. The Committee for Advanced Therapies (CAT) has been established at the European Medicines Agency (EMA) for centralized classification, certification and evaluation procedures, and other ATMP-related tasks. Guidance documents, initiatives, and interaction platforms are available to make the new framework more accessible for small- and medium-sized enterprises, academia, hospitals, and foundation…
Preparation of speciality-integrated assignments in informatics study courses at the higher education level
2012
Information and communications technologies today are used in virtually any university course when students prepare their papers. ICT is also needed after people are graduated from university and enter the job market. This author is an instructor in the field of informatics related to health care and social sciences at the Riga Stradins University. In practice, he has found that after completing informatics courses (IC) at the university level, students and practicing specialists at various levels find it hard to decide on what data processing method to use in order to interpret extracted results in the relevant area of specialisation. There are various data processing methods in the litera…
A Conceptual Framework for Using and Evaluating Web-Based Learning Resources in School Education
2010
Published version of an article from the journal:Journal of Information Technology Education. Also available from the publisher: http://www.jite.org/documents/Vol9/JITEv9p053-079Hadjerrouit743.pdf Web-based learning resources (WBLRs) have provided teachers with a wide range of new teachingexperiences that are not possible in traditional classroom. However, little research has beendone as to which approach to WBLRs is suitable to address issues that are pertinent to learning.This paper proposes a conceptual framework to explore the design and evaluation of WBLRs inschool education. The paper also examines the way in which the framework is used to evaluatestudents? and teachers? perceptions o…
Il codice Pontecorvo
2016
Gli ultimi lavori di Pontecorvo, dopo il congedo dal cinema pensato per il grande schermo avvenuto con Ogro. Una serie di documentari, perlopiù regie collettive dal taglio politico e militante, con l’eccezione del cortometraggio Nostalgia di protezione. Il successo di Un altro mondo è possibile, il film sul G8 di Genova del 2001. L’addio definitivo, e il simbolico passaggio del testimone con suo figlio Marco. Esiste un “lascito” cinematografico del regista? L’influenza sul cinema americano contemporaneo, dalla New Hollywood in poi, e qualche equivoco. Alcuni possibili “eredi”, in Italia e all’estero.
La competencia textual y mediática en el aula de ELE
2017
Resumen: La habilidad de comprender y producir textos es una de las competencias basicas en la sociedad de la informacion y de la comunicacion (OECD, 2000). Sin embargo, el concepto texto ha evolucionado adquiriendo una versatilidad que rebasa la concepcion tradicional de texto escrito. Para superar este desfase al que la competencia lectora o las destrezas en la comprension y/o expresion oral no llegan, se propone desde Alemania el termino competencia textual y mediatica [1] . La finalidad de esta comunicacion es reflexionar sobre la importancia de esta nueva competencia y dotar al profesorado de herramientas en el tratamiento de la competencia textual en el aula de ELE. Para ello, present…
Plasma membrane redox system in the erythrocytes of rowers: Pilot study
2017
The oxidative stress results from a change in the physiological balance between oxidant and antioxidant species. This type of stress is a chemical change in the redox state of cells. The increased production of reactive species is related to an excessive metabolic activation, for example, from an intense physical exercise or an excessive caloric intake (1). In physiological conditions, muscle fibers are provided with an antioxidant system able to keep under control the excessive production of Reactive Oxygen Species (ROS).
Heading at Enabling Settings for Learning
2021
The paper draws on two cases of learning settings that were converted to meet up-to-date educational requirements within these learning contexts. The authors address the role of stakeholder perspectives. Focusing on the learning situation, they present an articulation tool to aid dialogue between key stakeholder perspectives in a (re)design process. Dialogue is a way to figure out relevant issues and to establish the common ground between participants. The goal of a redesign process is that user requirements are well understood, and the design is embedded into local practices, informed of constraints and aware of potential opportunities regarding educational technology.
