Numerical model for material parameter identification of cells
Bacteria have a complex external layer that render them with an increased stiffness and more resistant to external invasion. The works aims to model the squeezing of a bacteria between two walls, and deduce the composition of bacterial external layer from the observed deformations. A FE based model will be developed for inferring the stiffness of baceria, solving an inverse problem from the applied loading and measured displacements. The results will be applied to laboraotry experiments carried out at Institu of Bioengineering of Catalunya (IBEC)

Algo más sobre la vocación medievalista de Vicente Aguilera Cerni
El propósito de este artículo es el de ampliar la información (hasta ahora publicada), de la actividad historiográfica medievalista de Vicente Aguilera Cerni, llevada a cabo durante sus primeros años de investigación sobre el arte valenciano, antes de dedicarse por completo al estudio del arte contemporáneo. En él se da cumplida cuenta de su planteamiento metodológico, así como de su especial interés por el gótico y los pintores llamados «primitivos» valencianos, especialmente Jacomart.The purpose of this article is to broaden the information that has been published so far on Vicente Aguilera Cerni’s medieval historiographical activity, carried out during his early years of research on Valencian art, before devoting himself entirely to the study of contemporary art. Here, the reader will find a detailed explanation on his methodological approach and his particular interest in Gothic art and the so-called «primitive» Valencian painters, especially Jacomart
El peruano Juan Gargurevich, en la avanzada de los estudios teóricos e históricos sobre periodismo
For almost 40 years (after a long period working as a journalist) the Peruvian professor Juan GARGUREVICH has dedicated to his lectures on journalism, developed into classroms and books writing. Many articles and essays were fruit of his research in the field of Journalistic style, making an historical and contemporary approach to peruvian journalism. This academic labour was recognized not only in Perú, but also in other sudamerican countries. This scientific and critical view also appears in new books and trade union activities. Nowadays, he’s the director of “Club de Periodistas del Perú” (Peruvian Journalists Union).Desde hace casi cuarenta años (después de un largo período en el ejercicio profesional) el profesor peruano Juan GARGUREVICH se ha dedicado a sus lecciones sobre periodismo, tanto en las aulas como en los libros. Fruto de esta dedicación son los trabajos académicos que ha publicado sobre géneros periodísticos, que alcanzaron gran difusión en los países de su entorno, y sobre la historia y el presente de la prensa de su país. Una visión científica y crítica que se manifiesta con nuevas obras, pero también con una presencia activa en el mundo gremial (ahora al frente del Club de Periodistas del Perú)
Pragmatic analysis of a royal interview
En muy pocas ocasiones se ha sometido el Rey de España a una entrevista periodística. Cuando aceptó hablar con el periodista Jesús Hermida a través de Televisión Española con motivo de su 75 cumpleaños, los espectadores hubieran deseado presenciar un diálogo fluido sobre las grandes cuestiones que les preocupan, pero el resultado no estuvo a la altura de estas expectativas. Cuando más se aleja la entrevista de las reglas de la conversación (atrevida por parte del periodista y cooperadora por parte del entrevistado) menos calidad alcanza y menos satisfacción produce.Rarely has the King of Spain agreed a journalistic interview. When he accepted to talk to journalist Jesús Hermida in Spanish Television on the occasion of his 75 birthday, viewers wished to witness a fluid dialogue on major issues that concern them: the result didn’t respond to these expectations. The more interview moves away from conversation rules (defiant on the part of journalist and cooperative on the part of the interviewee) the less quality and satisfaction produces
A transaction cost approach to strategic alliances in telecommunications
An emerging form of international business organization is the strategic alliance, a species of joint-venture in which an innovator of technology contracts with another firm for the joint exploitation of technology and other assets across a number of national territories. This work will examine international alliances, applying insights from both the transaction cost and foreign investment theories to the telecommunications service industry and asking whether these cooperation agreements are economically efficient or they restrict competition between companies formerly operating in a domestic regulated environment. In this context, alliances have played an increasing role in the development of firms' strategies arising as a rational economic solution to market impeffections caused by high ownership costs (or ownership constraints) and information asyrnmetry. Thus, most of these alternative institutional forms can be assigned characteristics, which are intermediate between those of the market and the hierarchy and can be viewed as vertical or horizontal integration of economic activities, while ownership remains separate, and preserve the flexibility and economic rents these specific arrangements generate
Cooperación y competencia en el sector de las telecomunicaciones: las alianzas estratégicas internacionales
Las alianzas tecnológicas internacionales constituyen una forma de organización, semejante a las joint-ventures,
en las que uno o más innovadores realizan un acuerdo de cooperación con otras empresas, para la explotación
conjunta de la tecnología y otros activos intangibles, en una serie de países. En este articulo analizamos el papel
de las alianzas estratégicas en el sector de las telecomunicaciones, tanto desde el punto de vista de los costes de
transacción, como de su aplicación a la inversión internacional, para conocer si estos acuerdos son eficientes
desde el punto de vista económico o, por el contrario, limitan la competencia entre las empresas que, con anterioridad,
operaban en un mercado regulado. Las alianzas permiten, en determinados supuestos, reducir costes
de funcionamiento, mientras conservan las ventajas económicas derivadas de su mayor flexibilidad organizativa.Publicad
Surface movement and cascade processes on debris cones in temperate high mountain (Picos de Europa, northern Spain)
Producción CientíficaDebris talus is a very common landform in the temperate high mountain, so much so that it is the most representative of the periglacial and nival processes. This work studies debris cones in the Picos de Europa, an Atlantic mountain range in the north of the Iberian Peninsula. A detailed geomorphological map was prepared, fieldwork was carried out on the debris cone surface, the ground and air thermal regime was analyzed, and a five-year Terrestrial Laser Scan survey carried out. Annual volume changes on the surface of the debris cones were detected and related to active processes and sediment transfer. Two different behaviors were observed in each cone. Cone A is linear, with equilibrium between accumulation and sediment transfer, while Cone B is concave-convex denoting accumulation processes in the upper part deriving from the greater frequency of snow avalanches. Changes in morphology surpass 50 cm/year with most of the activity taking place in the highest and lowest areas. The presence and action of the ice on the debris slope are moderate or non-existent and freeze-thaw processes are only active on the walls at over 2000 m a.s.l. The main processes on debris cones are debris flow and creep related to snowcover, but sediment transfer on the slopes involves high intensity-low frequency (debris flow, avalanches) and high frequency-low intensity processes (creep, shift, solifluction and wasting).Ministerio de Economía, Industria y Competitividad - Fondo Europeo de Desarrollo Regional (project CGL2015-68144-R)Junta de Extremadura - Fondo Europeo de Desarrollo Regional (project GR10071
Modelling and Terrestrial Laser Scanning Methodology (2009–2018) on Debris Cones in Temperate High Mountains
Producción CientíficaDebris cones are a very common landform in temperate high mountains. They are the
most representative examples of the periglacial and nival processes. This work studies the dynamic
behavior of two debris cones (Cone A and Cone B) in the Picos de Europa, in the north of the
Iberian Peninsula. Their evolution was measured uninterruptedly throughout each August for
10 years (2009–2018) using the Terrestrial Laser Scanning (TLS) technique. The observations and
calculations of the two debris cones were treated independently, but both showed the same behavior.
Therefore, if these results are extrapolated to other debris cones in similar environments (temperate
high mountain), they should show behavior similar to that of the two debris cones analyzed. Material
falls onto the cones from the walls, and transfer of sediments follows linear trajectories according to
the maximum slope. In order to understand the linear evolution of the two debris cones, profiles were
created along the maximum slope lines of the Digital Elevation Model (DEM) of 2009, and these profile
lines were extrapolated to the remaining years of measurement. In order to determine volumetric
surface behavior in the DEMs, each year for the period 2009–2018 was compared. In addition,
the statistical predictive value for position (Z) in year 2018 was calculated for the same planimetric
position (X,Y) throughout the profiles of maximum slopes. To do so, the real field data from 2009–2017
were interpolated and used to form a sample of curves. These curves are interpreted as the realization
of a functional random variable that can be predicted using statistical techniques. The predictive
curve obtained was compared with the 2018 field data. The results of both coordinates (Z), the real
field data, and the statistical data are coherent within the margin of error of the data collection.Fondo Europeo de Desarrollo Regional - Agencia Estatal de Investigación (grant TIN2016-76843-C4-2-R)Ministerio de Economía, Industria y Competitividad - Fondo Europeo de Desarrollo Regional (grant CGL2015-68144-R
