Magnetic excitations in La-based cuprate superconductors: slave-boson mean-field analysis of the two-dimensional t-J model

description: Motivated by recent inelastic neutron scattering experiments up to a high-energy region for La-based cuprates, we compute (q,omega) maps of the imaginary part of the dynamical magnetic susceptibility chi(q,omega) in the slave-boson mean-field approximation to the two-dimensional t-J model. While the strong spectral weight appears at incommensurate positions, namely at q neq Q =(pi,pi), for low energy, the incommensurate signals disperse with increasing omega and finally merge into a commensurate signal at a particular energy omega=omega_Q. These features are seen in both the d-wave pairing state and the normal state. In particular, the incommensurate signals below omega_Q in the normal state are due to the Fermi surface geometry, which we expect for La-based cuprates because of a tendency to d-wave type Fermi surface deformations. Above omega_Q, strong signals appear to trace an upward dispersion especially for a low doping rate in the d-wave pairing state while typically broad spectral weight is obtained around q=Q in the normal state. Salient features of magnetic excitations in La-based cuprates are thus naturally captured in terms of particle-hole excitations. Global understanding of magnetic excitations in high-Tc cuprates is discussed through a comparison with magnetic excitations in YBa_2Cu_3O_y.

Teaching and learning mathematics using Wall Math in a grade 1 classroom
Creators: name: Bateson, D. Lynne
Publisher: name: University of British Columbia
Year: 2009

description: This study explored students' interactions with a primary mathematics programme, Wall Math, as it operated in a single Grade 1 classroom. The programme, based on constructivist principles, as exemplified by Cognitively Guided Instruction, and conforming to both the British Columbia Ministry of Education's instructional resources package for Kindergarten to Grade 7 and the National Council of Teachers of Mathematics' standards, employs a structured set of questions which are posted on a wall of the classroom for students to work on over several class periods. The programme is designed to provide students with meaningful learning opportunities for the intended learning outcomes of the primary programme, while also providing constant review and repetition of important skills. In addition, the programme provides students with opportunities to develop personally and socially as they interact with their teacher and fellow students. This study followed primarily six Grade 1 students (three boys and three girls of varying mathematical abilities: high, average, and low) through a series of five sets ("boards") of problems over a period of approximately three months. A narrative style is used to illustrate how the students dealt with both new and review material, and how the students interacted with the questions, their teacher, and each other.

description: We build detailed composite models of photoionization and shock ionization based on the SUMA code to reproduce emission lines emitted from the Narrow Line Regions (NLR) of Seyfert 2 nuclei. The aim of this work is to investigate diagram AGN positions according to shock parameters, shock effects on the gas temperature and ionization structures and derive a semi-empirical abundance calibration based on emission-line ratios little sensitive to the shock presence. The models were used to reproduce optical (3000 < A < 7000) emission line intensities of 244 local (z < 0.4) Seyfert 2s, whose observational data were selected from Sloan Digital Sky Survey DR7. Our models suggest that shocks in Seyfert 2 nuclei have velocities in the range of 50-300 km/s and imply a narrower metallicity range (0.6 < (Z/Z) < 1.6) than those derived using pure photoionization models. Our results indicate that shock velocity in AGNs can not be estimated using standard optical line ratio diagrams, based on integrated spectra. Our models predict a different temperature structure and O+/O and O2+/O fractional abundances throughout the NLR clouds than those derived from pure photoionization models, mainly in shock-dominated objects. This suggests that, in order to minimize the shock effects, the combination of emission-lines emitted by ions with similar intermediate ionization potential could be good metallicity indicators. Finally, we derive two calibrations between the N/O abundance ratio and the N2O2=log([N II]6584/[O II]3727) and N2=log([N II]6584/Hα) indexes which agree with that derived from pure photoionization models.

description: We address the dynamical and statistical description of stably stratified turbulent boundary layers with the important example of the atmospheric boundary layer with a stable temperature stratification in mind. Traditional approaches to this problem, based on the profiles of mean quantities, velocity second-order correlations, and dimensional estimates of the turbulent thermal flux run into a well known difficulty, predicting the suppression of turbulence at a small critical value of the Richardson number, in contradiction with observations. Phenomenological attempts to overcome this problem suffer from various theoretical inconsistencies. Here we present an approach taking into full account all the second-order statistics, which allows us to respect the conservation of total mechanical energy. The analysis culminates in an analytic solution of the profiles of all mean quantities and all second-order correlations removing the unphysical predictions of previous theories. We propose that the approach taken here is sufficient to describe the lower parts of the atmospheric boundary layer, as long as the Richardson number does not exceed an order of unity. For much higher Richardson numbers the physics may change qualitatively, requiring careful consideration of the potential Kelvin-Helmoholtz waves and their interaction with the vortical turbulence.

description: In this paper, we propose a combined modeling of molecular mechanics (MM) and the tight-binding (TB) approach, which enables us to study the effect of factors such as external local forces, constraints, and vacancy defects on electronic transport properties of nanomaterials. Nanostructures selected in this work are armchair graphene nanoribbons (AGNRs). According to this method, the nanostructure is modeled as a frame, and the beam element is applied for illustrating the covalent interatomic interactions in bonds. In our calculations, the terms of torsional, stretching, and bending energies are considered. The selected pristine nanoribbon is a metal, and the purpose of this study is to find the effects of mechanical loading, the vacancy defects and their positions on the electrical conductance of the structure. We observe that the presence of vacancy defects in the structure leads to the opening of an energy gap, which changes the phase of the nanostructure from metal to the semiconductor. We find that with increasing the number of point defects, the energy gap size of the strained system grows. Besides, increasing the magnitude of the local force reduces the conductance, and the energy gap of the system. By changing parameters such as the number of point defects and magnitude local forces, the transport gap of the system can be controlled. The results of this research may be useful in the design of nanoelectromechanical systems.

description: We present the first public version of Caravel, a C++17 framework for the computation of multi-loop scattering amplitudes in quantum field theory, based on the numerical unitarity method. Caravel is composed of modules for the $D$-dimensional decomposition of integrands of scattering amplitudes into master and surface terms, the computation of tree-level amplitudes in floating point or finite-field arithmetic, the numerical computation of one- and two-loop amplitudes in QCD and Einstein gravity, and functional reconstruction tools. We provide programs that showcase Caravel's main functionalities and allow to compute selected one- and two-loop amplitudes.

description: We discuss how adiabatic potentials can be used to create addressable lattices on a subwavelength scale, which can be used as a tool for local operations and readout within a lattice substructure, while taking advantage of the faster timescales and higher energy and temperature scales determined by the shorter lattice spacing. For alkaline-earth-like atoms with non-zero nuclear spin, these potentials can be made state dependent, for which we give specific examples with $^{171}$Yb atoms. We discuss in detail the limitations in generating the lattice potentials, in particular non-adiabatic losses, and show that the loss rates can always be made exponentially small by increasing the laser power.

Effect of rate of change of parameter on early warning signals for critical transitions

description: Many dynamical systems exhibit abrupt transitions or tipping as the control parameter is varied. In scenarios where the parameter is varied continuously, the rate of change of control parameter greatly affects the performance of early warning signals (EWS) for such critical transitions.We study the impact of variation of the control parameter with a finite rate on the performance of \textcolor{black}{EWS for critical transitions} in a thermoacoustic system (a horizontal Rijke tube) exhibiting subcritical Hopf bifurcation. There is a growing interest in developing early warning signals for tipping in real systems. Firstly, we explore the efficacy of early warning signals based on critical slowing down and fractal characteristics. From this study, lag-1 autocorrelation (AC) and Hurst exponent H are found to be good measures to predict the transition well-before the tipping point. The warning time, obtained using AC and $H$, reduces with an increase in the rate of change of the control parameter following an inverse power law relation. Hence, for very fast rates, the warning time may be too short to perform any control action. Furthermore, we report the observation of a hyperexponential scaling relation between the AC and the variance of fluctuations during such dynamic Hopf bifurcation. We construct a theoretical model for noisy Hopf bifurcation wherein the control parameter is continuously varied at different rates to study the effect of rate of change of parameter on EWS. Similar results, including the hyperexponential scaling, are observed in the model as well.

description: The root-mean-square (rms) nuclear charge radius of ^8He, the most neutron-rich of all particle-stable nuclei, has been determined for the first time to be 1.93(3) fm. In addition, the rms charge radius of ^6He was measured to be 2.068(11) fm, in excellent agreement with a previous result. The significant reduction in charge radius from ^6He to ^8He is an indication of the change in the correlations of the excess neutrons and is consistent with the ^8He neutron halo structure. The experiment was based on laser spectroscopy of individual helium atoms cooled and confined in a magneto-optical trap. Charge radii were extracted from the measured isotope shifts with the help of precision atomic theory calculations.

description: A simple explicit example of a Roberts-type dynamo is given in which the alpha-effect of mean-field electrodynamics exists in spite of point-wise vanishing kinetic helicity of the fluid flow. In this way it is shown that alpha-effect dynamos do not necessarily require non-zero kinetic helicity. A mean-field theory of Roberts-type dynamos is established within the framework of the second-order correlation approximation. In addition numerical solutions of the original dynamo equations are given, that are independent of any approximation of that kind. Both theory and numerical results demonstrate the possibility of dynamo action in the absence of kinetic helicity.

description: După Unirea de la 1 decembrie 1918, într-un climat care, din punct de vedere istorico-social tindea spre stabilitate, s-a înființat, în data de 18 iulie 1921, Episcopia Vadului, Feleacului și Clujului, cu reședința la Cluj și cu jurisdicția canonică peste teritoriile din dreapta Mureșului. În data de 15/28 septembrie 1921, asesorul Nicolae Ivan (1855-1936) a fost ales, apoi înscăunat, episcop al Clujului, păstorind până la moarte[1].  

            Simțind nevoia revigorării și intensificării vieții duhovnicești din noua eparhie, imediat după înscăunarea sa, episcopul Nicolae Ivan a redactat și înaintat o serie de memorii către Ministerul Cultelor și Artelor, Ministerul Instrucțiunii Publice și Senatul Universitar Cluj, cu scopul de a înființa, la Cluj, o Academie de Teologie. Ideea episcopului Ivan era aceea de a crea un cadru instituțional care să permită inițierea unui program de pregătire pentru viitorii preoți. În urma memoriilor și a insistențelor episcopului Ivan, în ziua de 7 mai 1924, s-a dat citire, în cadrul ședinței Adunării eparhiale de la Cluj, actului consistorial nr. 2871/1924, care face referire la întemeierea Institutului Teologic de la Cluj[2]. Existând un temei legal pentru fondarea unei instituții de învățământ superior, în data de 20 iunie 1924, prin adresa nr. 3913, s-a declanșat procedura de concurs pentru ocuparea posturilor didactice. În acest sens, s-au folosit toate mijloacele de informare, în special editorialele bisericești: Renașterea (Cluj), Telegraful Român (Sibiu), Biserica Ortodoxă Română (București) și Candela (Cernăuți), în care au fost anunțate posturile vacante la catedrele de discipline teologice, care urmau să funcționeze în cadrul Institutului nou înființat.

description: When a metallic specimen is plastically deformed, its underlying crystal structure must often rotate in order to comply with its macroscopic boundary conditions. There is growing interest within the dynamic compression community in exploiting x-ray diffraction measurements of lattice rotation to infer which combinations of plasticity mechanisms are operative in uniaxially shock- or ramp-compressed crystals, thus informing materials science at the greatest extremes of pressure and strain rate. However, it is not widely appreciated that several of the existing models linking rotation to slip activity are fundamentally inapplicable to a planar compression scenario. We present molecular dynamics simulations of single crystals suffering true uniaxial strain, and show that the Schmid and Taylor analyses used in traditional materials science fail to predict the ensuing lattice rotation. We propose a simple alternative framework based on the elastoplastic decomposition that successfully recovers the observed rotation for these single crystals, and can further be used to identify the operative slip systems and the amount of activity upon them in the idealized cases of single and double slip.

description: We show that, within some modified gravity theories, such as the Palatini models, the non-linear nature of the field equations implies that the usual naive averaging procedure (replacing the microscopic energy-momentum by its cosmological average) could be invalid. As a consequence, the relative motion of particles in Palatini theories is actually indistinguishable from that predicted by General Relativity. Moreover, there is no WEP violation. Our new and most important result is that the cosmology and astrophysics, or put more generally, the behaviours on macroscopic scales, predicted by these two theories are the same, and as a result the naturalness problems associated with the cosmological constant are not alleviated. Palatini gravity does however predict alterations to the internal structure of particles and the particle physics laws, e.g., corrections to the hydrogen energy levels. Measurements of which place strong constraints on the properties of viable Palatini gravities.

Η παστερίωση επηρέασε την ωρίμανση του τυριού. Η διάσπαση της αs1 και β-καζεΐνης ήταν υψηλότερη στο R απ’ ότι στο P τυρί. Η β-CN παρουσίασε μεγαλύτερη αντοχή στην πρωτεόλυση καθ’ όλη την περίοδο ωρίμανσης και στα δύο τυριά. Το ίδιο παρατηρήθηκε και για τα προϊόντα της λιπόλυσης. Η οσμή, γεύση και δομή-υφή του τυριού από νωπό γάλα, προτιμήθηκε απ’ ότι εκείνη του παστεριωμένου γάλακτος.
description: Experimental cheeses of Graviera Kritis cheese were made from raw (R) and pasteurized (P) milk to study the influence of pasteurization on the cheese microflora, the composition of non starter lactic acid bacteria (NSLAB) and the cheese proteolysis and lipolysis. LAB were the predominated microflora in both cheeses. Heat treatment lowered (P<0.05) the levels of all microbial group; it also affected considerably the composition of the NSLAB early in ripening. In the curd of R cheese lactobacilli predominated, while in P cheese curd enterococci were the most abundant NSLAB microbial group; from 4 days onwards, lactobacilli were found with increased frequencies till the end of ripening. The main lactococcus species was Lact. lactis subsp. lactis. L. paracasei subsp. paracasei predominated over the other NSLAB in the mature cheese. Ent. faecalis was the most frequently found among Enterococcus species. Pasteurization also influenced cheese ripening. Degradation of αs1-casein and β-casein was in R>P cheese. The β-CN exhibited greater resistance to proteolysis over the entire period in both cheeses. The same was observed with the lipolysis products. The flavor and texture of R was preferred to P cheese.

description: The present essay deals with the presentation and appraisal of the provisions of Directive 2006/123/EC on services in the internal market (Services Directive- SD) in the EU with regard to the contemporary jurisprudence of the European Court of Justice concerning the freedom of establishment and the freedom to provide services in Europe; in addition, it is argued that the aforementioned interpretation of the ECJ about these two EC fundamental freedoms and the restrictions imposed by the member states, has had a significant impact on the adoption of the final text of the Directive. The first parts of the essay sketch the way towards the adoption of the Services Directive and its purpose, subject matter and scope of application; the next part examines the relationship of the Services Directive with other provisions of primary and secondary EU law as well as with other fields of law and policies; the last part examines the substantive provisions of the Services Directive concerning the freedom of establishment and the free movement of services, emphasizing on the rights of recipients of services.

description: Context: Over the last decade, several groups of young (mainly low-mass) stars have been discovered in the solar neighbourhood (closer than ~100 pc), thanks to cross-correlation between X-ray, optical spectroscopy and kinematic data. These young local associations -- including an important fraction whose members are Hipparcos stars -- offer insights into the star formation process in low-density environments, shed light on the substellar domain, and could have played an important role in the recent history of the local interstellar medium. Aims: To study the kinematic evolution of young local associations and their relation to other young stellar groups and structures in the local interstellar medium, thus casting new light on recent star formation processes in the solar neighbourhood. Methods: We compiled the data published in the literature for young local associations. Using a realistic Galactic potential we integrated the orbits for these associations and the Sco-Cen complex back in time. Results: Combining these data with the spatial structure of the Local Bubble and the spiral structure of the Galaxy, we propose a recent history of star formation in the solar neighbourhood. We suggest that both the Sco-Cen complex and young local associations originated as a result of the impact of the inner spiral arm shock wave against a giant molecular cloud. The core of the giant molecular cloud formed the Sco-Cen complex, and some small cloudlets in a halo around the giant molecular cloud formed young local associations several million years later. We also propose a supernova in young local associations a few million years ago as the most likely candidate to have reheated the Local Bubble to its present temperature.

description: The depletion and variations of groundwater storage~(GWS) are of critical importance for sustainable groundwater management. In this work, we use Gravity Recovery and Climate Experiment (GRACE) to estimate variations in the terrestrial water storage~(TWS) and use it in conjunction with the Global Land Data Assimilation System~(GLDAS) data to extract GWS variations over time for Indus river basin~(IRB). We present a data processing framework that processes and combines these data-sets to provide an estimate of GWS changes. We also present the design of a band-limited optimally concentrated window function for spatial localization of the data in the region of interest. We construct the so-called optimal window for the IRB region and use it in our processing framework to analyze the GWS variations from 2005 to 2015. Our analysis reveals the expected seasonal variations in GWS and signifies groundwater depletion on average over the time period. Our proposed processing framework can be used to analyze spatio-temporal variations in TWS and GWS for any region of interest.

description: Η εργασία διαλέγεται με κάποιες από τις μετα-μοντέρνες αναγνώσεις του Montesquieu και επισημαίνοντας τα κενά σε αφορισμούς περί φεμινοκεντρισμού ή κοσμοπολιτισμού της γραφής του, επιβεβαιώνει τον ευρωκεντρισμό/ανδροκεντρισμό του προτάγματός του. Δομείται σε 4 κεφάλαια. Τα δύο πρώτα αφορούν στο πλαίσιο, σε θεωρητικά και μεθοδολογικά ζητήματα καθώς και στο συγγραφέα. Η σχέση του Montesquieu με την ετερότητα εντάχθηκε στον ευρύτερο διάλογο της μεταμοντέρνας ανάγνωσης των διαφωτιστικών κειμένων. Η ιστορία των αναγνώσεων του ίδιου δομήθηκε με τρόπο τέτοιο ώστε να φανεί η αντιφατικότητα που τις χαρακτηρίζει και να συναχθούν ερωτήματα. Η απάντηση τους επιχειρήθηκε στα επόμενα δυο κεφάλαια τα οποία και αποτελούν την προσωπική ερμηνευτική πρόταση. Ακολουθούν, ως είθισται, τα καταληκτικά συμπεράσματα και ο συνηθισμένος βιβλιογραφικός οδηγός.
description: The essay gets into dialogue with some of the post modern receptions of Montesquieu. Questioning the feminocentrism/cosmopolitism of his writing suggests an interpretation which confirms the eurocentrism/paternalism of his argument. It is structured in 4 chapters; The first 2 refer to theoretical and methodological issues as well as to the writer. The relation of Montesquieu with the other (in race/gender) was included in the wider dialogue of the postmodern reating of Enlightenment texts. The history of his' reception was structured so as to show its inconsistency and to draw questions. Their answer was attempted in the next two chapters which are the personal interpretive proposal. The final conclusions are followed, as usual, by the bibliographic guide.

description: It is shown that a number of key observations of the Galactic ISM can be understood, if it is treated as a highly compressible and turbulent medium energized predominantly by supernova explosions (and stellar winds). We have performed extensive numerical high resolution 3D hydrodynamical and magnetohydrodynamical simulations with adaptive mesh refinement over sufficiently long time scales to erase memory effects of the initial setup. Our results show, in good agrement with observations, that (i) volume filling factors of the hot medium are modest (typically below 20%), (ii) global pressure is far from uniform due to supersonic (and to some extent superalfvenic) turbulence, (iii) a significant fraction of the mass (about 60%) in the warm neutral medium is in the thermally unstable regime (500 K < T < 5000 K), (iv) the average number density of OVI in absorption is 1.81 10^{-8} cm^{-3}, in excellent agreement with Copernicus and FUSE data, and its distribution is rather clumpy, consistent with its measured dispersion with distance.

description: Cubic spinel GeNi2O4 exhibits intriguing magnetic properties with two successive antiferromagnetic phase transitions (TN1 12.1 and TN2 11.4 K) with the absence of any structural transition. We have performed detailed heat capacity and magnetic measurements in different crystallographic orientations. A new magnetic phase in presence of magnetic field (H > 4 T) along the [111] direction is revealed, which is not observed when the magnetic field is applied along the [100] and [110] directions. High field neutron powder diffraction measurements confirm such a change in magnetic phase, which could be ascribed to a spin reorientation in the presence of magnetic field. A strong magnetic anisotropy and competing magnetic interactions play a crucial role on the complex magnetic behavior in this cubic system.

description: The focus of this study was ancient slag of mining activites from the Eastern Macedonian region dated on the Byzantine period (13th-16th century). More specifically, we studied forty samples of slag from four regions of mining activity, namely Agistro, Makrichori, Katafyto and Vathytopo. Analyses of these slag were carried out using X-ray Diffraction Spectroscopy (XRD) and Inducively Coupled Plasma Emission Spectroscopy (ICP-AES). Through the results of the experiments an attempt was made to answer the questions of archaeologists regarding metallurgical technology during the Byzantine era.
Reentry: a proactive collaborative study: the long term needs of an individual during reacculturation
Creators: name: Smith, Janet Ellen
Publisher: name: University of British Columbia
Year: 2009

description: The experiences of many sojourners returning home after living abroad has often resulted in difficulties associated with reacculturation. Having conducted training for and experiencing reentry myself on several occasions, I recognized how unprepared we are for the circumstances which present themselves to us upon returning home. Reentry programs and studies in the past have generally identified the causal effects and provided suggestions in an attempt to enhance returnees' acculturation. Debriefing or reorientation workshops have been offered previous to arrival home or within the first few months afterwards. However, the long term needs of the individual returnee have not been examined. The purpose, of this study was to investigate the long term needs of the individual returnees which enable them to develop proactive strategies for successful reacculturation. Using Collaborative Participatory Research, the returnee and I co-investigated Tanya's story. We examined her transitional experiences as the story unfolded through the phases of predeparture, arrival home and honeymoon period, adjustment and final integration. This investigation consisted of nine 1.5 hour interviews. These occurred in three series, each containing three interviews which were two to three months, five to six months, and nine to ten months after the returnee's arrival home. Through self reflection and self assessment the returnee was able to identify her own needs of readaptation and develop proactive coping strategies. She was able to recognize that her difficult experiences were part of a growthful experience and that her reacculturation is still on-going. The final chapter of this study briefly examines and recommends further study for the issues of concern which have emerged as a result of this investigation. This study found that returnees can benefit from an ongoing exploration of their long term needs preferably in co-operation with an experienced support person. Also that past values, perceptions and life experiences are inextricably woven together to create a total experience for the returnee. While returnees experiences are universally similar, they are at the same time uniquely individual. Further research is needed to investigate the aspects of the long term influences and effects of reentry.

description: A first-principles density functional method along with the direct solution of linearized Boltzmann transport equations are employed to systematically analyze the low-temperature thermal transport in crystalline GeTe. The extensive thermal transport simulations, ranging from room temperature to cryogenic temperatures, reveal the emergence of a phonon hydrodynamic regime in GeTe at low temperature. The reduction of grain boundary scattering is found to play a crucial role along with the divergent trend of umklapp and normal scattering at low temperatures in accommodating the hydrodynamic regime. Average scattering rates for normal, umklapp, and other resistive processes are distinguished for a wide range (4-300 K) of temperatures and used for identifying various phonon transport regimes. Therefore, the variations of lattice thermal conductivity, phonon propagation length, and thermal diffusivity with temperature, related to these transport regimes (ballistic, hydrodynamic, and kinetic), have been thoroughly investigated. The modewise decomposition of lattice thermal conductivity and the distinction of thermal diffusivity according to different scattering processes reveal rich information on the dominant phonon modes and phonon scattering processes in GeTe at low temperature. Further, the kinetic-collective model is used to elucidate the hydrodynamic behavior of phonon scattering through the relative study of collective and kinetic contributions to the thermal transport properties. In this context, the Knudsen number is estimated through the characteristic nonlocal length and the grain size, which further quantifies the consistent hydrodynamic behavior of phonon thermal transport for GeTe. Finally, phonon-vacancy scattering for GeTe is realized, and vacancies are found strongly to influence the hydrodynamic window while incorporating the other resistive scattering mechanisms.

description: Ο Κομμοδιανός είναι ίσως ο πιο αινιγματικός και προβληματικός ποιητής των Ύστερων Αυτοκρατορικών χρόνων. Δεν έχουμε πολλές πληροφορίες για τον ποιητή. Σώζεται μόνο μία μαρτυρία στο De viris illustribus του Γενναδίου από την Μασσαλία. Ο Κομμοδιανός πιθανόν ήταν αφρικανικής καταγωγής και έζησε τον τρίτο αιώνα μ.Χ.. Όμως υπάρχουν πολλές διχογνωμίες μελετητών πάνω στα συγκεκριμένα ζητήματα. Το σίγουρο είναι ότι έγραψε τους Instructiones, που αποτελούνται από δύο βιβλία: μία συλλογή 80 ποιημάτων σε δαχτυλικό εξάμετρο που στρέφονται κατά των παγανιστών και των Εβραίων. Επίσης έργο του θεωρείται και το carmen apologeticum που αποτελείται από 1060 εξαμέτρους και κάνει λόγο για τον πόλεμο μεταξύ του Θεού και του διαβόλου, την Δευτέρα Παρουσία και την Θεία Κρίση. Το C.A. δεν έχει ποτέ ως τώρα μεταφραστεί στα νέα ελληνικά. Η παρούσα εργασία προσπαθεί να παραθέσει μια, όσο το δυνατόν πιστότερη, μετάφραση συνοδευόμενη από έναν πλούσιο πραγματολογικό, ερμηνευτικό και κειμενικό σχολιασμό. Επίσης παρατίθεται μια αναλυτική εισαγωγή για τον βίο, τις πηγές και τη συγγραφική δραστηριότητα του Κομμοδιανού.
description: Commodian is maybe the most enigmatic and mysterious Christian poet. Unfrotunately, we don’t know much about him. We only have a testimony of De viris illustribus of Gennadius from Marseilles. Commodian is probably an African of the third century A.D. Even nowadays researchers don’t agree on many topics about him. He wrote Instructiones, which consists of two books: a collection of eighty poems written in hexameter against pagans and Judish. He also wrote one carmen apologeticum, a poem of 1060 hexameters, which narrates Old Testament and the fight between God and Devil in the Second Coming and the Divine Judgement. Τhe C.A. has never been translated in Modern Greek. This thesis tries to offer a translation, as much as possible close to the original text, combined with a rich pragmatological, interpretative and based to the text comment. In addition, it offers an analytical introduction to Commodian’s life, resourses and writing action.
