description: Η τελευταία τάση στο χώρο της ερμηνείας του αρχαίου δράματος είναι το "μεταθέατρο", το θέατρο δηλ. του οποίου η προβληματική είναι κατά βάση αυτοαναφορική, αφού εστιάζεται στο ίδιο το θέατρο και στην ιδιότητά του ως παιγνίου που διεξάγεται σε ελεγχόμενες συνθήκες, στους όρους παραγωγής και παράστασής του, στις συμβάσεις και την αποτελεσματικότητά τους, στην εγρήγορση αυτοσυνηδησία του ποιητή-τεχνίτη, στην τέχνη του υποκριτή και στο ρόλο του θεατή. Στόχος της παρούσας μελέτης είναι να επαναξετάσει το ζήτημα της μεταθεατρικής ερμηνείας της ελληνικής τραγωδίας. Στο πλαίσιο αυτό διερευνώνται φαινόμενα, όπως η προσφώνηση του ακροατηρίου, οι αυτοαναφορές του ποιητή στην τέχνη που υπηρετεί, το "θέατρο εν θεάτρω", η θεατρική παράσταση ως θεσμός, καθώς και η χρήση θεατρικής ορολογίας. Η μέθοδος που ακολουθείται είναι κατά βάση κειμενοκεντρική. Το συμπέρασμα που προκύπτει είναι ότι με μεταθεατρική ανάγνωση στίχων και σκηνών, ευρύτερων δραματικών επεισοδίων και ολόκληρων δραμάτων/βάκχων παραβιάζονται βασικές συμβάσεις του λογοτεχνικού είδους της τραγωδίας, αφού η εφαρμογή μεταθεατρικών ερμηνειών υποβιβάζει σε σημασία στοιχεία που για την αρχαιοελληνική τραγωδία είναι συστατικά και αποτελεί a priori προβολή των σύγχρονων ερμηνευτικών προσδοκιών επί των αρχαίων κειμένων
description: The latest trend in ancient drama interpretation is "metatheatre". The term pertains to a kind of self-referential theatre, which focuses on the theatre perse and on its status as a game played under controlled environment. It also examines the terms of theatrical production and performance, theatrical conventions and their effectiveness, while delving in the poet's self reference to its art, the play-within-the-play and the use of theatrical terminology. The method is based on the text and on the analysis of the strictly dramatic function of its constituents. The metatheatrical reading of selected verses and scenes, episodes and whole plays(Bacchae) leads to the violation of basics conventions of tragedy as a literary genre. The structuralistic philosophy of metatheatre is rather the a priori projection of modern hermeneutical expectations on classical texts

description: What remains of a geometrical notion like that of a principal bundle when the base space is not a manifold but a coarse graining of it, like the poset formed by a base for the topology ordered under inclusion? Motivated by finding a geometrical framework for developing gauge theories in algebraic quantum field theory, we give, in the present paper, a first answer to this question. The notions of transition function, connection form and curvature form find a nice description in terms of cohomology, in general non-Abelian, of a poset with values in a group $G$. Interpreting a 1--cocycle as a principal bundle, a connection turns out to be a 1--cochain associated in a suitable way with this 1--cocycle; the curvature of a connection turns out to be its 2--coboundary. We show the existence of nonflat connections, and relate flat connections to homomorphisms of the fundamental group of the poset into $G$. We discuss holonomy and prove an analogue of the Ambrose-Singer theorem.
Sustainable business models for sustainable decision making: an application to reusing offshore gas platforms in the Adriatic Sea

description: This paper suggests an empirical methodology to use theoretical Sustainable Business Models (SBMs) in making sustainable (i.e., participatory decisions involving economic, social and environmental features) and rational (i.e., informed and consistent) decisions with respect to what, who, where, when, and how to do. The case study, focused on alternative reuses of offshore gas platforms (i.e., a complicated case due to the absence of previous stakeholders’ experiences at local and national level), identified when (i.e., the end as opposed to the beginning of extraction activities) and where (i.e., the economic, social and environmental contexts of the Adriatic Sea in Abruzzo region, Italy). A questionnaire, submitted to stakeholders, produced the relative weights required by the tested SBM (i.e., a comprehensive model recently proposed by Lüdeke-Freund et al., 2018); it reached a conclusion about how (i.e., in favour of majority decisions as opposed to representative decisions); and it highlighted a sample size issue (i.e., solved with a 50% increase of stakeholders involved). In summary, the methodology suggested in this paper applied to a comprehensive SBM for a complicated case study produced an empirical sustainable decision which is consistent with relative weights expressed by stakeholders. However, this decision is theoretically wrong, since eco-design (empirically correlated with the proper institutional approach for who) should have been preferred to circular economy (empirically correlated with the proper cooperative approach for who). In other words, information gaps about what (mainly due to an overemphasis put on social features) must be solved with additional meetings between experts and stakeholders.

description: The Clebsch method provides a unifying approach for deriving variational principles for continuous and discrete dynamical systems where elements of a vector space are used to control dynamics on the cotangent bundle of a Lie group \emph{via} a velocity map. This paper proves a reduction theorem which states that the canonical variables on the Lie group can be eliminated, if and only if the velocity map is a Lie algebra action, thereby producing the Euler-Poincaré (EP) equation for the vector space variables. In this case, the map from the canonical variables on the Lie group to the vector space is the standard momentum map defined using the diamond operator. We apply the Clebsch method in examples of the rotating rigid body and the incompressible Euler equations. Along the way, we explain how singular solutions of the EP equation for the diffeomorphism group (EPDiff) arise as momentum maps in the Clebsch approach. In the case of finite dimensional Lie groups, the Clebsch variational principle is discretised to produce a variational integrator for the dynamical system. We obtain a discrete map from which the variables on the cotangent bundle of a Lie group may be eliminated to produce a discrete EP equation for elements of the vector space. We give an integrator for the rotating rigid body as an example. We also briefly discuss how to discretise infinite-dimensional Clebsch systems, so as to produce conservative numerical methods for fluid dynamics.

description: We consider one-loop five-point QCD amplitudes in next-to-multi-Regge kinematics, and evaluate the one-loop impact factor for the emission of two gluons. This is the last ingredient which is necessary to evaluate the gluon-jet impact factor at NNLO accuracy in $\as$. It is also the first instance in which loop-level QCD amplitudes are evaluated in next-to-multi-Regge kinematics, which requires to apply a different reggeisation ansatz to each colour-ordered amplitude.

description: Parmi le matériel didactique que l’espagnol hétérodoxe Juan de Luna, exilé en France puis en Angleterre, publia au cours de sa longue carrière de maître de langue figurent onze dialogues de sa plume, parus à trois dates différentes : 1616, 1619 et 1623. A chacune de ces dates se trouve un dialogue intitulé Diálogo entre un maestro y un discípulo. Les liens complexes entre l’ensemble des différents dialogues ont à ce jour peu été étudiés. Cet article a pour objet la version de 1623 du Diálogo entre un maestro y un discípulo. Après un bref rappel biobibliographique à propos de l’auteur, on se propose ici de l’analyser de façon à montrer que, si le but de l’auteur est bien lexicographique on trouve cependant, a minima, les structures de l’interaction conversationnelle propre au dialogue didactique qui instaure des liens étroits avec ses deux prédécesseurs.

description: Observations show that at least some gamma-ray bursts (GRBs) happen simultaneously with core-collapse supernovae (SNe), thus linking by a common thread nature's two grandest explosions. We review here the growing evidence for and theoretical implications of this association, and conclude that most long-duration soft-spectrum GRBs are accompanied by massive stellar explosions (GRB-SNe). The kinetic energy and luminosity of well-studied GRB-SNe appear to be greater than those of ordinary SNe, but evidence exists, even in a limited sample, for considerable diversity. The existing sample also suggests that most of the energy in the explosion is contained in nonrelativistic ejecta (producing the supernova) rather than in the relativistic jets responsible for making the burst and its afterglow. Neither all SNe, nor even all SNe of Type Ibc produce GRBs. The degree of differential rotation in the collapsing iron core of massive stars when they die may be what makes the difference.

Οι έως τώρα προσεγγίσεις ένα πρόβλημα που ήταν μέρος του Ανατολικού Ζητήματος και άρα έπρεπε να ειδωθεί βάσει των διεθνών εξελίξεων και της πολιτικής των Μ. Δυνάμεων. Γι'αυτό και η διατριβή στηρίχθηκαν κυρίως σε διπλωματικά αρχεία των Υπ. Εξωτερικών Ελλάδας, ΗΠΑ, μ. Βρετανίας και Γαλλίας. Από το πρωοχρησιμοποιούμενο πρωτογενές υλικό και την ανασύνθεση των έως τώρα γνωστών στοιχείων προέκυψαν νέα στοιχεία, όπως η έντονη κινητικότητα που παρουσιάσθηκε στο ζήτημα το καλοκαίρι του 1917 και ο καίριος ρόλος των ΗΠΑ το 1919 που οδήγησαν σε νέα συμπεράσματα. Επιγραμματικά η κίνηση απέτυχε λόγω της απουσίας πολιτικής οργάνωσης και εμπειρίας των Ποντίων, της οικονομικής αδυναμίας και της πληθυσμιακής εξασθένησής τους μετά τη γενοκτονία και τους διωγμούς του Α' Παγκοσμίου Πολέμου, της έλλειψης σαφούς στοχοθέτησης του αγώνα, της αδυναμίας εξασφάλισης βοήθειας από Μ.

description: The thesis presents the whole effort of the movement and tries with the analysis of the international and tropical developmets to explain the reasons of the failure. The approaches of the issues until now faced the question topical. Nevertheless the problem was part of the Eastern Question and for that should be approached in a basis of international developments and the policy of the G. Powers. For theat reason the thesis be based on the archives of the Foreign Ministries of Greece, USA, G. Britain and France. From this material and the recomposition of the known elements arose new elements which leaded in new conclusions. Epigrammatically the movement failed because of the absence of political organization, the economical weaknes, and the population decline after the genocide, the lack of clearly aim, the fragmentation of the movement, the belated mobilization, the absence of popular base and armed revolt, the embarrassed policy of Venizelos, the negative attitude of the G. Powers and midless attitude of the Armenians. However the effort of the Greek of Pontus can not be regarded as hopeless. But they stay stick with old-fashioned ideas about the attitude of the G. Powers. Essentially the desirable is presumed possible from the Pontic Greek, and for that reason they failed

description: We report on time-resolved photoluminescence from semiconductor microcavities showing that an optically controllable mechanism exists to turn on and off memory effects in a polariton system. By increasing the laser pumping pulse intensity we observe revivals of the decaying time-resolved photoluminescence signal, a manifestly non-Markovian behavior of the optically active polaritons. Based on an open quantum system approach we perform a comprehensive analytical and numerical study of the coupling of optically active polaritons to a structured reservoir to confirm the origin of the observed features. Our findings show that negative detunings and strong excitation should occur simultaneously for memory effects to take place.

Επιδιώχθηκε να παρουσιαστούν και να ερμηνευτούν εκείνες οι διαδικασίες, μέσω των οποίων η εκκλησία επηρέασε και συμμετείχε στην πολιτική απέναντι στις κομματικές εξελίξεις, αλλά επιχείρησε κιόλας να προσαρμόσει το δημόσιο λόγο του στις μεταβαλλόμενες πολιτικές συνθήκες της περιόδου του Ελληνικού Μεσοπολέμου.

Χρησιμοποιώντας σημαντικό αριθμό πρωτογενών και δευτερογενών πηγών, αποδεικνύεται πως ο θρησκευτικός παράγοντας και ο πολιτικός-κομματικός σχετίζονται στενά και εξαρτώνται μεταξύ τους.

description: The present historical thesis examines the question of the political speech and role of the Church of Greece during the period right after the end of the two Balkan Wars and until the first months of the German Occupation. It sought to present and interprete those proceedings, through which the Church influenced and participated in the political life of the state. Indeed, the clergy not only didn't stay impassive to the partisan evolutions, but it also tried to adjust it's public speech to the different political corcumstances of the Greek Middle-War period. It's purpose was to protect it's economic survival and it's administrative independence towards all political regimes, whether democratic, revolutional or dictatorial; effort that was more or less successful. By using and important amount of primary and secondary sources, it is aproved that the religious factor and the political-partisan one are close related and dependent to each other; this relation was primary an outcome of the fact that religion was considered to be a part of the wider state organization
Alfven wave heating in partially ionized thin threads of solar prominences

description: There is observational evidence of the presence of small-amplitude transverse magnetohydrodynamic (MHD) waves with a wide range of frequencies in the threads of solar prominences. It is believed that the waves are driven at the photosphere and propagate along the magnetic field lines up to prominences suspended in the corona. The dissipation of MHD wave energy in the partially ionized prominence plasma is a heating mechanism whose relevance needs to be explored. Here we consider a simple 1D model for a non-uniform thin thread and investigate the heating associated with dissipation of Alfven waves. The model assumes an ad hoc density profile and a uniform pressure, while the temperature and ionization degree are self-consistently computed considering either LTE or non-LTE approximations for the hydrogen ionization. A broadband driver for Alfven waves is placed at one end of the magnetic field line, representing photospheric excitation. The Alfvenic perturbations along the thread are obtained by solving the linearized MHD equations for a partially ionized plasma in the single-fluid approximation.We find that wave heating in the partially ionized part of the thread is significant enough to compensate for energy losses due to radiative cooling. A greater amount of heating is found in the LTE case because the ionization degree for core prominence temperatures is lower than that in the non-LTE approximation. This results in a greater level of dissipation due to ambipolar diffusion in the LTE case. Conversely, in the hot coronal part of the model, the plasma is fully ionized and wave heating is negligible. The results of this simple model suggest that MHD wave heating can be relevant for the energy balance in prominences. Further studies based on more elaborate models are required.

description: We study the tunneling time of Dirac fermions in graphene magnetic barrier through an electrostatic potential and a mass term. This latter generates an energy gap in the spectrum and therefore affects the proprieties of tunneling of the system. For clarification, we first start by deriving the eigenspinors solutions of Dirac equation and second connect them to the incident, reflected and transmitted beam waves. This connection allows us to obtain the corresponding phases shifts and consequently compute the group delay time in transmission and reflection. Our numerical results show that the group delay time depends strongly on the energy gap in the tunneling process through single barrier. Moreover, we find that the group approaches unity at some critical value of the energy gap and becomes independent to the strengths of involved physical parameters.

description: A large class of two dimensional quantum gravity theories of Jackiw-Teitelboim form have a description in terms of random matrix models. Such models, treated fully non-perturbatively, can give an explicit and tractable description of the underlying ``microstate'' degrees of freedom. They play a prominent role in regimes where the smooth geometrical picture of the physics is inadequate. This is shown using a natural tool for extracting the detailed microstate physics, a Fredholm determinant ${\rm det}(\mathbf{1}{-}\mathbf{ K})$. Its associated kernel $K(E,E^\prime)$ can be defined explicitly for a wide variety of JT gravity theories. To illustrate the methods, the statistics of the first several energy levels of a non-perturbative definition of JT gravity are constructed explicitly using numerical methods, and the full quenched free energy $F_Q(T)$ of the system is computed for the first time. These results are also of relevance to quantum properties of black holes in higher dimensions.

description: As high-performance organic semiconductors, π-conjugated polymers have attracted much attention due to their charming advantages including low-cost, solution processability, mechanical flexibility, and tunable optoelectronic properties. During the past several decades, the great advances have been made in polymers-based OFETs with p-type, n-type or even ambipolar characterics. Through chemical modification and alignment optimization, lots of conjugated polymers exhibited superior mobilities, and some mobilities are even larger than 10 cm2 V-1 s-1 in OFETs, which makes them very promising for the applications in organic electronic devices. This review describes the recent progress of the high performance polymers used in OFETs from the aspects of molecular design and assembly strategy. Furthermore, the current challenges and outlook in the design and development of conjugated polymers are also mentioned.

description: We address the problem of indoor layout synthesis, which is a topic of continuing research interest in computer graphics. The newest works made significant progress using data-driven generative methods; however, these approaches rely on suitable datasets. In practice, desirable layout properties may not exist in a dataset, for instance, specific expert knowledge can be missing in the data. We propose a method that combines expert knowledge, for example, knowledge about ergonomics, with a data-driven generator based on the popular Transformer architecture. The knowledge is given as differentiable scalar functions, which can be used both as weights or as additional terms in the loss function. Using this knowledge, the synthesized layouts can be biased to exhibit desirable properties, even if these properties are not present in the dataset. Our approach can also alleviate problems of lack of data and imperfections in the data. Our work aims to improve generative machine learning for modeling and provide novel tools for designers and amateurs for the problem of interior layout creation.

description: A partir de septiembre de 1934 se publicó en Italia una revista especializada en lenguas extranjeras que se llamó Le lingue estere. La revista estuvo activa hasta 1950, con una pausa breve (1944-1945) en la parte del Segundo conflicto mundial que fue más complicada para Italia y que naturalmente lo fue para una revista nacida en el marco del fascismo: ya en los meses de octubre, noviembre y diciembre, después del armisticio, Le lingue estere no salió con los tres –o más, en ciertos casos– números habituales, sino con un número único; retomó sus actividades en enero de 1946. Poco conocida también entre los que estudian la historia de la enseñanza de las lenguas extranjeras en Italia, la revista ha puesto siempre el español entre las cuatro lenguas principales de su labor de difusión y seguramente, por lo que concierne la lengua española, sería interesante un estudio sistemático, que comprendiera también su transformación, en 1951, en Le lingue del mondo. Unica rivista italiana di cultura linguistica. Hasta enero de 1946 –poco antes de su muerte, que ocurrió en febrero–, el redactor especializado en la lengua española fue Carlo Boselli, reconocido traductor, autor de gramáticas y diccionarios, profesor en centros de enseñanza extra-universitarios, cuyas publicaciones más difundidas, como sus dos diccionarios bilingües (1900, 1937 y respectivas reediciones) y la Grammatica spagnola del XX secolo (1940) ya han sido estudiadas en esclarecidos trabajos de Félix San Vicente, María Cristina Bordonaba, Estefanía Flores Acuña. En esta contribución nos proponemos estudiar su trabajo de divulgador y profesor en la revista, proporcionando también informaciones generales sobre la revista misma y lo que publicaba en español o con relación a la lengua española y a las culturas relacionadas con ella. Esto se conecta también con libros publicados por Le lingue estere –que era también una editorial– y que proceden directamente de la revista, como los cursos cuatrilingües publicados inicialmente por entregas, y da lugar, asimismo, a la constatación de una evidente intertextualidad entre los artículos que Boselli publicó en Le lingue estere y sus otras obras, como el manual Sorprese dello spagnolo (Guida allo studio della lingua spagnola) edito più volte fino agli anni settanta dello scorso secolo.

description: Η διατριβή επικεντρώνεται στη ζωή, τη δραστηριότητα και τη καλλιτεχνική δημιουργία των αδελφών Μαργαρίτη : στις σπουδές, στη λειτουργία και την παραγωγή των εργαστηρίων τους , στην ενασχόληση με νέες και εφαρμοσμένες μορφές τέχνης-δηλ. του Γεωργίου με τη λιθογραφία και του Φίλιππου με τη φωτογραφία-στη διδασκαλία του στο Σχολείο τω Τεχνών και σ'αυτή του Γεωργίου στη Σχολή Ευελπίδων. Ιδιαίτερη βαρύτητα δίνεται στην εφεύρεση και διάδοση της φωτογραφίας στον ευρωπαϊκό χώρο, στην κριτική αντιμετώπισή της, στην εισαγωή της στην Ελλάδα και στους φωτογράφους που δραστηριοποιήθηκαν στην Αθήνα μετά την ίδρυση του φωτογραφικού εργαστηρίου του Φίλιππου Μαργαρίτη. Βασική επιδίωξη αποτελεί η ένταξη της δραστηριότητας των δύο καλλιτεχνών στο γενικότερο ιδεολγογικό πλαίσιο της εποχής και η ανάδειξη του ρόλου τους στην εξέλιξη της ελληνικής τέχνης και στην διαμόρφωση της εικαστικής σκηνής και της αισθητικής του κοινού στην Αθήνα του 19ου αιώνα
description: The thesis focuses on the life and artistic activity of the Margaritis brothers : on their studies, on the function and the production of their ateliers, on their turn towards applied arts, on their teaching at the Athens School of Arts and that of Georgios at the Military School. An important part is dedicated on the invention and development of photography in Europe its critical confrontation, on its emergence in Greece and on photographers that worked in Athens after Philippos Margaritis. The basic aim is to place the activity of the two artists in the development of greek art

description: We report three manifestly Lorentz-invariant Hamiltonian formulations of minimally and nonminimally coupled fermion fields to the Holst action. These formulations are achieved by making a suitable parametrization of both the tetrad and the Lorentz connection, which allows us to integrate out some auxiliary fields without spoiling the local Lorentz symmetry. They have the peculiarity that their noncanonical symplectic structures as well as the phase-space variables for the gravitational sector are real. Moreover, two of these Hamiltonian formulations involve half-densitized fermion fields. We also impose the time gauge on these formulations, which leads to real connections for the gravitational configuration variables. Finally, we perform a symplectomorphism in one of the manifestly Lorentz-invariant Hamiltonian formulations and analyze the resulting formulation, which becomes the Hamiltonian formulation of fermion fields minimally coupled to the Palatini action for particular values of the coupling parameters.

description: Fin dalla sua fondazione all’inizio del XX secolo, il Conservatoire Lassalle di Montréal promuove il perfezionamento della lingua orale delle élites francofone orientando la norma fonetica verso il modello parigino. Nei decenni successivi questa evoluzione è favorita dallo sviluppo dalle scuole di dizione, fra le quali si distingue quella di Madame Jean-Louis Audet, insegnante di fonetica, animatrice di corsi radiofonici e collaboratrice della Société du Bon parler di Montréal. L’influenza dei suoi insegnamenti su diverse generazioni di montrealesi è confermata dalle numerose riedizioni, fra il 1938 e il 1967, dei suoi Monologues du Petit- Monde, una raccolta di testi utilizzati nei corsi rivolti ai bambini, accompagnati da commenti metodologici e da riflessioni critiche. Pensato per insegnanti e genitori, il volume permette di ricostruire il metodo correttivo di Madame Audet e di rilevare, in una prospettiva di sociolinguistica storica, i tratti della pronuncia più stigmatizzati tra gli anni 1930 e 1960.
Wandering of the central black hole in a galactic nucleus and correlation of the black hole mass with the bulge mass

description: We investigate a mechanism for a super-massive black hole at the center of a galaxy to wander in the nucleus region. A situation is supposed in which the central black hole tends to move by the gravitational attractions from the nearby molecular clouds in a nuclear bulge but is braked via the dynamical frictions by the ambient stars there. We estimate the approximate kinetic energy of the black hole in an equilibrium between the energy gain rate through the gravitational attractions and the energy loss rate through the dynamical frictions, in a nuclear bulge composed of a nuclear stellar disk and a nuclear stellar cluster as observed from our Galaxy. The wandering distance of the black hole in the gravitational potential of the nuclear bulge is evaluated to get as large as several 10 pc, when the black hole mass is relatively small. The distance, however, shrinks as the black hole mass increases and the equilibrium solution between the energy gain and loss disappears when the black hole mass exceeds an upper limit. As a result, we can expect the following scenario for the evolution of the black hole mass: When the black hole mass is smaller than the upper limit, mass accretion of the interstellar matter in the circum-nuclear region, causing the AGN activities, makes the black hole mass larger. However, when the mass gets to the upper limit, the black hole loses the balancing force against the dynamical friction and starts spiraling downward to the gravity center. From simple parameter scaling, the upper mass limit of the black hole is found to be proportional to the bulge mass and this could explain the observed correlation of the black hole mass with the bulge mass.
Radius and chirality dependent conformation of polymer molecule at nanotube interface

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: Temperature dependent conformations of linear polymer molecules adsorbed at carbon nanotube (CNT) interfaces are investigated through molecule dynamics simulations. Model polyethylene (PE) molecules are shown to have selective conformations on CNT surface, controlled by atomic structures of CNT lattice and geometric coiling energy. PE molecules form entropy driven assembly domains, and their preferred wrapping angles around large radius CNT (40, 40) reflect the molecule configurations with energy minimums on a graphite plane. While PE molecules prefer wrapping on small radius armchair CNT (5, 5) predominantly at low temperatures, their configurations are shifted to larger wrapping angle ones on a similar radius zigzag CNT (10, 0). A nematic transformation around 280 K is identified through Landau-deGennes theory, with molecule aligning along tube axis in extended conformations

Impact loading of timber beams
Creators: name: Jansson, Bengt
Publisher: name: University of British Columbia
Year: 2008

description: Static tests as well as impact tests were performed to build up our knowledge about impact loading of timber beams. The investigation was focused on failure modes and failure stresses. The static tests were conducted using both deformation and load controlled regimes at three different loading rates in a MTS test machine. The single blow impact tests were carried out with three different drop-heights using a drop-weight impact machine built at the University of British Columbia. A total of 651 specimens (38 x 89 x 1145 mm) were sorted into two categories. The specimens were then grouped into the various loading groups according to the modulus of elasticity obtained from non-destructive bending tests. Three different dynamic failure stress analyses were applied and compared with each other. The distributed inertial forces were replaced with a mid-point inertial force in the first analysis, which was based upon accelerometer measurements. The accelerometer measurements from these tests were considered very unreliable. The second analysis employed a very detailed finite element program which went beyond the objectives of this thesis. The third analysis was a modal analysis, which was a mode-superposition analysis of a distributed-parameter system. The modal analysis was used throughout the remaining analysis because its solution was easily divided into its static and dynamic parts, and it was more efficient than the second analysis. The strength ratio, which was the ratio between dynamic and static failure stress, reflected the effect of impact loading better than the traditional duration of load theory. Non-parametric percentile values of the strength ratio based on the distribution of strength ratios were found more appropriate than if these percentile values were based on the distribution of failure stresses. No differences in failure stresses were observed between the different static tests. A strength decrease of 15 % was experienced for the weaker specimen. The overall tendency was that the number of compression initiated failures de-creased with decreasing failure time. The decrease in failure strength with decreasing failure time was explained by the decreasing amount of compression initiated failure modes.

description: En los Institutos de Economía y Comercio, ya desde su creación, se introdujo la enseñanza de las lenguas extranjeras modernas: alemán, español, francés e inglés, lo cual, sin duda, representa un dato de gran interés en el ámbito de su enseñanza. Esto, junto al hecho de convertirse en centros de enseñanza superior a nivel universitario otorga a las lenguas modernas un rango y una importancia de gran relieve desde el punto académico, social y económico. El estudio de la presencia de la asignatura de español en las universidades italianas, tomando como base el curso 1934-1935, permite perfilar bien la situación no solo de su enseñanza institucional, sino también de la consideración cultural y social de que era objeto. En este trabajo se analiza la distribución de la enseñanza del español en los Institutos Superiores de Economía y Comercio y en las Facultades de Filosofía y Letras. La comparación de los datos entre los dos tipos de entes universitarios muestra cómo, en el ámbito ministerial, la consideración que recibía la lengua española no se basaba en su prestigio cultural sino en sus posibilidades prácticas de aplicación a las relaciones comerciales. Con el análisis realizado se ha obtenido una fotografía de los centros de enseñanza del español en 1935, así como de los perfiles de los profesores en activo, de sus características, del tipo de plaza docente que ocupaban y de las obras que publicaron. Por último, con este estudio se ha podido constatar cómo la observación de un periodo del pasado, aunque breve, ayuda a interpretar las claves del presente universitario respecto a las lenguas modernas y, en concreto, a la lengua española.
