association study

description: MiRNA-associated genetic variants occurring in regulatory regions can affect the efficiency of transcription and potentially modify pri-miRNA or pre-miRNA processing. Since miRNA-based mechanisms are shown to be involved in the pathogenesis of prostate cancer (PCa), the aim of the present study was to evaluate the effect of rs4938723, rs1076064 and rs4705343 occurring in regulatory regions of miR-34b/c, miR-143/145 and miR-378, respectively, on PCa risk and progression in Serbian population. We examined a total of 1060 subjects, of which 350 were patients with PCa, 354 were patients with benign prostatic hyperplasia (BPH), while 356 healthy volunteers were included in the control group. Genotyping of rs4938723, rs1076064 and rs4705343 was performed by using Taqman® SNP Genotyping Assays. Allele C of rs4705342 was found to increase the risk of PCa (P=0.031 for codominant model, P=0.0088 for recessive model). Rs1076064 minor allele G was found to associate with serum PSA score, as well as with PCa T category and disease aggressiveness. For rs4938723 minor allele C was shown to be associated with the lower PCa T category (Pdom=0.0046; OR=0.36, 95 % CI 0.17-0.76) in T2 vs. T1 comparison. Rs4705342 was identified as PCa susceptibility variant in Serbian population, while for rs1076064 and rs4938723 association with PCa progression parameters was found.

Jahrhunderts findet, lässt sich auch Feindschaft mehr oder weniger deutlich mit Noten ausdrücken. In Kriegszeiten komponierten so auch heute noch beliebte Komponisten Stücke voll Verachtung und Aggression, deren Hintergrund Musikliebhabern meist gar nicht mehr bewusst ist. Erst in jüngster Zeit macht es sich die Musikwissenschaft zunehmend zur Aufgabe, solche verborgenen oder vergessenen Kon- und Subtexte aufzudecken.

description: This is a doctorate level lecture on the physics of accretion discs driving magnetically self-confined jets, usually referred to in the literature as disc winds. I will first review the governing magnetohydrodynamic equations and then discuss their physical content. At that level, necessary conditions to drive jets from keplerian accretion discs can already be derived. These conditions are validated with self-similar calculations of accretion-ejection structures. In a second part, I will critically discuss the biases introduced when using self-similarity as well as some other questions such as: Are these systems really unstable? Can a standard accretion disc provide the conditions to launch jets in its innermost parts? What is the difference between X-winds and disc-winds? Finally, the magnetic interaction between a protostar and its circumstellar disc will be discussed with a focus on stellar spin down.

description: In this thesis, the synthesis of numerous di(triaryl phosphines) with DPE- or DBF-backbone was investigated using the well-known (-)-ephedrine methodology established by S. Jugé and co-workers. These di(triaryl phosphines) were tested in asymmetric catalysis and examined in regard to their stereochemical stability. Additionally, a new route for the synthesis of a P-chirogenic BINAP-type di(triaryl phosphine) was developed starting from a P-chirogenic secondary phosphine borane.

description: A combination of out-of-plane and in-plane magnetoconductance (MC) study in topological insulators (TI) is often used as an experimental technique to probe weak anti-localization (WAL) response of the topological surface states (TSSs). However, in addition to the above WAL response, weak localization (WL) contribution from conducting bulk states are also known to coexist and contribute to the overall MC; a study that has so far received limited attention. In this article, we accurately extract the above WL contribution by systematically analyzing the temperature and magnetic field dependency of conductivity in Bi$_2$Se$_3$ films. For accurate analysis, we quantify the contribution of electron-electron interactions to the measured MC which is often ignored in recent WAL studies. Moreover, we show that the WAL effect arising from the TSSs with finite penetration depth, for out-of-plane and in-plane magnetic field can together explain the anisotropic magnetoconductance (AMC) and, thus, the investigated AMC study can serve as a useful technique to probe the parameters like phase coherence length and penetration depth that characterise the TSSs in 3D TIs. We also demonstrate that increase in bulk-disorder, achieved by growing the films on amorphous SiO$_2$ substrate rather than on crystalline Al$_2$O$_3$(0001), can lead to stronger decoupling between the top and bottom surface states of the film.

description: Mg2NiH4 is a promising hydrogen storage material with fast (de)hydrogenation kinetics. Its hydrogen desorption enthalpy, however, is too large for practical applications. In this paper we study the effects of transition metal doping by first-principles density functional theory calculations. We show that the hydrogen desorption enthalpy can be reduced by ~0.1 eV/H2 if one in eight Ni atoms is replaced by Cu or Fe. Replacing Ni by Co atoms, however, increases the hydrogen desorption enthalpy. We study the thermodynamic stability of the dopants in the hydrogenated and dehydrogenated phases. Doping with Co or Cu leads to marginally stable compounds, whereas doping with Fe leads to an unstable compound. The optical response of Mg2NiH4 is also substantially affected by doping. The optical gap in Mg2NiH4 is ~1.7 eV. Doping with Co, Fe or Cu leads to impurity bands that reduce the optical gap by up to 0.5 eV.

description: Doubly-degenerate binary systems consisting of two white dwarfs both composed of carbon and oxygen and close enough that mass is transferred from the less massive to the more massive are possible progenitors of type Ia supernovae. If the mass transfer rate is slow enough that the accreting white dwarf can reach 1.38 solar masses then it can ignite carbon degenerately at its centre. This can lead to a thermonuclear runaway and thence a supernova explosion. However if the accretion rate is too high the outer layers of the white dwarf heat up too much and carbon ignites there non-degenerately. A series of mild carbon flashes can then propagate inwards and convert the carbon to neon relatively gently. There is no thermonuclear runaway and no supernova. We have determined the critical rate for accretion and find it to be generally about two-fifths of the Eddington rate. In the case of actual bianry stars the mass transfer rate falls off as mass is transferred so we find that this rate can be very much exceeded at the onset of mass transfer. We determine combinations of white dwarf masses that can lead to central degenerate carbon ignition.

description: A common feature of electromagnetic emission from solar flares is the presence of intensity pulsations that vary as a function of time. Known as quasi-periodic pulsations (QPPs), these variations in flux appear to include periodic components and characteristic time-scales. Here, we analyse a GOES M3.7 class flare exhibiting pronounced QPPs across a broad band of wavelengths using imaging and time-series analysis. We identify QPPs in the timeseries of X-ray, low frequency radio and EUV wavelengths using wavelet analysis, and localise the region of the flare site from which the QPPs originate via X-ray and EUV imaging. It was found that the pulsations within the 171 Ȧ, 1600 Ȧ, soft X-ray (SXR), and hard X-ray (HXR) light curves yielded similar periods of $\sim$122 s, $\sim$131s, $\sim$123 s, and $\sim$137 s, respectively, indicating a common progenitor. The low frequency radio emission at 2.5 MHz contained a longer period of $\sim$231 s. Imaging analysis indicates that the location of the X-ray and EUV pulsations originates from a HXR footpoint linked to a system of nearby open magnetic field lines. Our results suggest that intermittent particle acceleration, likely due to 'bursty' magnetic reconnection, is responsible for the QPPs. The precipitating electrons accelerated towards the chromosphere produce the X-ray and EUV pulsations, while the escaping electrons result in low frequency radio pulses in the form of type III radio bursts. The modulation of the reconnection process, resulting in episodic particle acceleration, explains the presence of these QPPs across the entire spatial range of flaring emission.

description: We perform a detailed test of the quantum integrability of the AdS_5 x S^5 superstring in uniform light-cone gauge in its near plane-wave limit. For this we establish the form of the general nested light-cone Bethe equations for the quantum string from the long range psu(2,2|4) Bethe equations of Beisert and Staudacher. Moreover the scheme for translating excited string states into Bethe root excitations is given. We then confront the direct perturbative diagonalization of the light-cone string Hamiltonian in the near plane-wave limit with the energy spectrum obtained from the general nested light-cone Bethe equations in various higher rank sectors. The analysis is performed both analytically and numerically up to the level of six impurity states and subsectors of maximal rank four. We find perfect agreement in all cases lending strong support to the quantum integrability of the AdS_5 x S^5 superstring.

description: 1. Wildlife in cities divides people, with some animals bringing positive benefits and others causing conflict, for example due to property damage. 2. Urban wildlife professionals from municipal administration, nature conservation, and hunting associations have a crucial role in shaping human-wildlife relationships in cities and fostering conflict-free coexistence. While many studies on urban wildlife have focused on the views of citizens, few have investigated the perspectives of experts to date. To address this knowledge gap, we interviewed 36 urban wildlife professionals giving guidance in the context of urban wildlife management, either in one of the four largest German cities by population (Berlin, Hamburg, Munich and Cologne) or at the national level. 3. Red foxes, wild boars, raccoons, stone martens and Eurasian beavers were the five mammal species most frequently highlighted in interviews to cause human-wildlife conflicts. The interviewees saw wild boars and raccoons as the most controversial urban wild mammals but emphasized the need to create refuges for beavers and better inform the public about foxes. 4. Management in terms of public outreach, urban planning and population control, as well as establishing official contact points and stricter fines of activities violating regulations were highlighted as important elements of a toolkit to manage urban wildlife conflicts.

description: We consider a system composed of a single artificial atom coupled to a cavity mode. The artificial atom is biased such that the most dominant relaxation process in the system takes the atom from its ground state to its excited state, thus ensuring population inversion. A recent experimental manifestation of this situation was achieved using a voltage-biased superconducting charge qubit. Even under the condition of `inverted relaxation', lasing action can be suppressed if the `relaxation' rate is larger than a certain threshold value. Using simple transition-rate arguments and a semiclassical calculation, we derive analytic expressions for the lasing suppression condition and the state of the cavity in both the lasing and suppressed-lasing regimes. The results of numerical calculations agree very well with the analytically derived results. We start by analyzing a simplified two-level-atom model, and we then analyze a three-level-atom model that should describe accurately the recently realized superconducting artificial-atom laser.

description: We simulate numerically the formation of spherically symmetric primordial black holes (PBHs) seeded by different families of primordial curvature perturbations profiles on a Friedman-Robertson-Walker (FRW) Universe filled by radiation fluid. We have studied the dependency on the curvature profile of the initial mass $M_{\rm BH,i}$ of the PBHs at the time of apparent horizon formation $t_{AH}$, and the final mass $M_{\rm BH,f}$ after the accretion process, using an excision technique, comparing $M_{\rm BH,i}$ to previous analytical estimations obtained using compensated PBHs model approach. The analytical estimations are in agreement with numerical results, except for large values of the initial perturbation amplitude, when the compensated model is less accurate. The masses $M_{\rm BH,f}$ and $M_{\rm BH,i}$ do not depend only on the shape around the compaction function peak, but on the full profile of the initial curvature perturbation. We also estimate the accretion effects, and for those PBHs with masses relevant for the dark matter abundance, with a final mass equal to the horizon crossing mass, we find $M_{\rm BH,f}\approx 3 M_{\rm BH,i} $.

description: Most population I Wolf-Rayet (WR) stars are the He-rich descendants of the most massive stars (M_i = 25 - 100 M_sun). Evidence has been accumulating over the years that among all pop I WR stars, those of the relatively cool, N-rich subtype "WN8" are among the most peculiar: 1. They tend to be runaways, with large space velocity and/or avoid clusters. 2. Unlike their equally luminous WN6,7 cousins, only a very small number of WN8 stars are known to belong to a close binary with an OB companion. 3. They are the systematically most highly stochastically variable among all (single) WR stars. Taken together, these suggest that many WN8 stars may originally have been in close binaries (like half of all stars), in which the original primary exploded as a supernova, leaving behind a very close binary containing a massive star with a neutron star/black hole companion (like Cyg X-3). When the massive remaining star evolved in turn, it engulfed and eventually swallowed the compact companion, leading to the presently puffed-up, variable WN8 star. Such stars could fall in the realm of the exotic Thorne-Zytkow objects.

description: Η διατριβή αναφέρεται στο ρόλο που κατείχε η ποίηση μέσα στο σχολείο αλλά και έξω από αυτό, στις στήλες του περιοδικού τύπου. Για τον καθορισμό των ποιοτικών κριτηρίων, μέσα από τα οποία μπόρεσε να προσεγγιστεί το ερευνητικό υλικό, στο πρώτο μέρος της διατριβής προηγήθηκε επισκόπηση των θεωρητικών προσεγγίσεων για τη φύση και λειτουργία της ποίησης και αναζητήθηκαν οι ιδιαιτερότητες της όταν αναφέρεται κυρίως σε παιδιά αναγνώστες. Στο Β' μέρος αξιολογήθηκαν τα ποιήματα με κεντρικούς άξονες τη θεματολογική τους επισήμανση και την ανάγνωση μορφής και περιεχομένου με όρους και εργαλεία από τη ρητορική και τη θεωρία της αφήγησης, με στόχο να διατυπωθεί η θέση του δημιουργού τους σε σχέση με τον αναγνώστη. Τα συμπεράσματα που προέκυψαν, οδήγησαν στην αναζήτηση των σκοπιμοτήτων που εξυπηρετήθηκαν στο συγκεκριμένο χρονικό διάστημα : Το είδος, η ιδεολογία και η αισθητική των ποιημάτων αποτέλεσαν δείγματα της εκάστοτε εκαπιδευτικής πολιτικής και των αναλυτικών προγραμμάτων που τα εκπροσώπησαν.

description: The subject of the present Thesis is the poetry in Greek elementary school books and children's periodicals during the period 1950-1990. In the first part of the Thesis a survey is presented of the theoretical approach to the nature and function of poetry taking into account the particularities of children as readers. This survey leads to a formulation of the qualitive and aesthetic criteria through which the poems are evaluated. In the second part of the Thesis the poems are evaluated according to their thematic and morphological content, making use of concepts and tools from the theory of Narrative, aiming to ascertain the poet's point of view to that of the(child) reader. The results of this evaluation lead to a quest of the purposes served during the above specific time period. It is shown that the aeschetic, the issues covered and the ideology behind the poems represent samples of the educational policies and the curricula that dominated then. It is also shown that the prejudices and stereotypes of that period regarding the mental skills of children had an effect on the poets and schoolbooks editors. Due to these policies children were deprived from sharing and enjoying real poetry
Modelling and experimental issues in the processing of composite laminates
Creators: name: Smith, Gregory David
Publisher: name: University of British Columbia
Year: 2008

description: Two published resin flow models for the autoclave/vacuum degassing process (AC/VD) have been implemented in a user friendly computer code. One, the sequential compaction flow model (SCM), includes a heat transfer model and the other, the squeezed sponge resin flow model (SSM), has been extended to include the same heat transfer model. An expression has been derived that makes the SSM mimic the resin pressure and lamina thickness predictions of the SCM. A parametric study of the effect of the lamina stress-strain behavior on the predicted resin pressure and laminae thickness profiles as a function of time has been conducted. The lamina stress-strain behavior has been found to greatly influence the compaction behavior of the laminate. Laminae with hardening stress-strain behavior, which is characteristic of real laminae, have the fastest compaction times. The predictions of the flow models have been compared to experimental laminates. Three laminates, two [0]24 and one [0/902/0]12, were laid-up with small postage stamped sized pressure sensors placed at the upper and lower surfaces and at the 1/4, 1/2 and 3/4 points through the thickness of the laminates and cured by the AC/VD process. The cure cycle was then simulated by the SCM and SSM models and their predictions compared to the sensor response monitored during the cure cycle. The experimental resin pressure profiles for both laminates showed that the resin flow begins very early in the cure cycle, much earlier than predicted by the SCM and about the same as predicted by the SSM. The laminate mass and thickness at the end of the cure cycle have been compared to the model predictions for all three laminates. For the 48 ply laminate the laminae thicknesses have also been compared to the model predictions. In all cases the best agreement was for the SSM model.
Politics, subjection and subjectivation : the microphysical corporeality of power in the theatrical works of Arthur Miller
Creators: name: Imam, Neamat
Publisher: name: Aristotle University of Thessaloniki
Year: 2003

description: This project looks at the theatrical works of Arthur Miller through the Faucauldian prism. It concentrates on the correlation, aggrandizement and sententiousness of modern power, as it preoccupies Miller's characters in their system of embodiment, insurgence for existence, rhetoric of dilemma and politics of freedom. On the one hand, the fantasies as well as the promises of self-stultification of the characters are observed to corroborate power's capacity of control, while, on the other, their condescension as well as cultivation of resentment is noted as inescapably subsiding in its playfulness. Power in Arthur Miller is not power proper, but its microphysical technologies and reflective prognosis. It is not limited to epistemologically developed influential issues it rather associates local, marginal and empirically unaccounted for uncertainties. It is a power expressed in subjectivation and exercised through tangential and nominalistic reciprocation. It plays more with the proliferation of identity, the consiousness industry, the vestiges of self-determination and the discursive stance of a subject than its scrupulus historico-political role and condition. It incarcerates the subject's body, manipulates its dreams and outflanks its desires. It engages the subject in a framework of transaction not only by essentializing in it a drive of hegemony or resistance, but also by creating a spell of erotico-masochistic gratification. Invisibility instead of corporal intervention is it process, mormalization instead of extinction its consequence. Even in the case of solidified hidtorical crises, i.e., Nazi transnational aggression, Judeo-Nordic racial confrontationm McCarthyite polarization of political ideologies and frustrating squandering of capital during the Depression, crises that appear and reappear in Miller's dramaturgy, power is fundamentally and predictably manifested at biopolitical level. It simultaneously engages and interacts with different conventionally divisible ingredients, i.e., nationalism, race, class, gender, thus illegitimizing their gridline of distinction and further bureaucratizing their functioning method

description: Highly integrated active nanophotonics addressing both device footprint and operation speed demands is a key enabling technology for the next generation optical networks. Plasmonic systems have proven to be a serious contender to alleviate current performance limitations in electro-optic devices. Here, we demonstrate a plasmonic optical phased array (OPA) consisting of two 10-$μ$m-long plasmonic phase shifters, utilized to control the far-field radiation pattern of two subwavelength-separated emitters for aliasing-free beam steering with an angular range of $\pm5^\circ$ and flat frequency response up to 18 GHz (with the potential bandwidth of 1.2 THz). Extreme optical and electrostatic field confinement with great spatial overlap results in high phase modulation efficiency ($V_πL=0.24\: \text{Vcm}$). The demonstrated approach of using plasmonic lithium niobate technology for optical beam manipulation offers inertia-free, robust, ultra-compact and high-speed beam steering.

description: Η εργασία αυτή σχεδιάστηκε με σκοπό να μελετήσει την επίδραση διαφορετικών προγραμμάτων εξάσκησης σε άτομα με ελαφρά Ν.Κ., στην εκτέλεση μιας σειράς αντιληπτικο-κινητικών δοκιμασιών. Στην εργασία έλαβαν μέρος 48 άτομα με ΔΝ 50-67 τα οποία χωρίσθηκαν σε 4 ομάδες των 12 ατόμων η κάθε μια. Πριν την εφαρμογή των προγραμμάτων διάρκειας 2 μηνών, τα άτομα μετρήθηκαν στην δοκιμασία ρίψης ελευθέρων βολών στην καλαθοσφαίριση. Η ίδια δοκιμασία επαναλήφθηκε μετά από 2 μήνες εξάσκησης με διαφορετικά προγράμματα εξάσκησης για τις 3 ομάδες και ελεύθερο παιγνίδι για την ομάδα ελέγχου. Η ιδια αντιληπτικο-κινητική δοκιμασία εξετάσθηκε μετά από 2 μήνες χωρίς την εφαρμογή προγραμμάτων. Από τα αποτελέσματα φάνηκε ότι μετά από την εφαρμογή των προγραμμάτων εξάσκησης, οι 3 ομάδες παρουσίασαν σημαντική βελτίωση ενώ η ομάδα ελέγχου δεν παρουσίασε μεταβολές. Μετά από 2 μήνες χωρίς την εφαρμογή των προγραμμάτων η επίδοση και των 4 ομάδων ήταν πτωτική. Προτείνεται η ευρεία εφαρμογή συστηματικών προγραμμάτων εξάσκησης σε άτομα με Ν.Κ. με σκοπό την καλυτέρευση των συνθηκών ζωής τους
description: This study was designed to assess the influence of different exercise programs for individuals with mild M.R. related to the performance of a perceptual-motor sequence test. 48 individuals participated in the study. The participants were assigned to four groups, 12 individuals each group. The duration of the exercise progras was 2 months and consisted of different intervention exercise programs for the experimental groups and free game of basketball for the control group. At the beginning of the intervention programs the individuals were assessed in the perceptual motor test of free throws in basketball. The participants performed 20 free throws during the initial test. After 2 months with the termination, they were assessed again, performing 20 free thows. There was a retention test 2 months later. The results showed that in 3 experimental groups was statistically significant downfall for all the groups. It is suggested a wider and more systematic application of these progams for a letter wvery day life for people with M.R.

description: Objectives: This study intends to describe the Andaman Sea circulation and investigate the dominant modes of variability in the basin. Analysis/Observations: The domain experiences stronger South-westerly winds from May to September and relatively weaker North-easterlies from November to February. A strong negative Ekman pumping along the north coast of Indonesia is observed during Summer. The transport of water across the straits of Andaman and Nicobar Islands (ANI) is computed by simple mass balance and is found to be in phase with the monthly averaged Mean Sea Level Anomalies (MSLA) of Andaman Sea. There occurs high surface outflux through Great channel and Ten-Degree channel in Summer. In April and October, rate of transport through the straits is maximum. During the same months, meridional surface currents intensify along the eastern boundary of the basin and are associated with signatures of downwelling. Findings: Intense down welling occurs to the north coast of Indonesia during Summer, locally forced by south-westerlies. There occurs large influx of water into Andaman Sea between April and November through the straits between the islands. Equatorial Wyrtki jets remotely force Kelvin waves of downwelling nature in the basin during April and October. The circulation in Andaman Sea is characterised by gyres or vortices, which is the manifestation of Rossby waves of semi-annual mode. The basin has a characteristic 120-day mode of westward propagating long Rossby wave packets which reflect from the coast of ANI as eastward propagating short Rossby waves. Novelty: The first attempt to completely describe the dynamics of Andaman Sea circulation exclusively from observations.

description: Traditional binned statistics such as $χ^2$ suffer from information loss and arbitrariness of the binning procedure. We point out that the underlying statistical quantity (the log likelihood $L$) does not require any binning beyond the one implied by instrumental readout channels, and we propose to use it for low-count data. The performance of $L$ in the model classification and point estimation problems is explored by Monte-Carlo simulations of Chandra and XMM X-ray spectra, and is compared to the performances of the binned Poisson statistic ($C$), Pearson's $χ^2$ and Neyman's $χ^2_N$, the Kolmogorov- Smirnov, and Kuiper' statistics. It is found that the unbinned log likelihood $L$ performs best with regard to the expected chi-square distance between true and estimated spectra, the chance of a successful identification among discrete candidate models, the area under the receiver-operator curve of reduced (two-model) binary classification problems, and generally also with regard to the mean square errors of individual spectrum parameters. The $χ^2$ ($χ^2_{\rm N}$) statistics should only be used if more than 10 (15) predicted counts per bin are available. From the practical point of view, the computational cost of evaluating $L$ is smaller than for any of the alternative methods if the forward model is specified in terms of a Poisson intensity and normalization is a free parameter. The maximum-$L$ method is applied to 14 observations from the Taurus Molecular Cloud, and the unbinned results are compared to binned XSPEC results, and found to generally agree, with exceptions explained by instability under re-binning and by background fine structures. The maximum-$L$ method has no lower limit on the available counts, and allows to treat weak sources which are beyond the means of binned methods.

Το τελευταίο ταξίδι του Οδυσσέα στην ιταλική λογοτεχνία
Creators: name: Russo-Καραλή, Giovannina
Publisher: name: Aristotle University of Thessaloniki
Year: 2003

description: Αντικείμενο της έρευνας υπήρξε ο μύθος του Οδυσσέα, που έχει ερμηνευτεί ποικιλοτρόπως στη διάρκεια των αιώνων αποκτώντας διαφορετική σήμανση ανάλογα με την ιστορική στιγμή και τα φιλοσοφικά, πολιτικά και πολιτιστικά ιδεώδη του κάθε πολιτισμού. Την εξέλιξη αυτού ακριβώς του μύθου παρακολουθήσαμε μέσα από τις διάφορες φάσεις της ιστορίας της ιταλικής λογοτεχνίας. Στο πλαίσιο αυτού του 'excursus' δόθηκε ιδιαίτερη σημασία στον Οδυσσέα ως τον κατ'εξοχήν ταξιδευτή και στο 'τελευταίο ταξίδι' του που, στην ιταλική λογοτεχνία, έχει συχνότερα σαν κατεύθυνση ένα 'αλλού' σε αντίθεση με τον ομηρικό 'νόστο'. Το πρώτο μέρος αυτής της εργασίας αναφέρεται στο δαντικό Οδυσσέα του 26ου άσματος της Κόλασης της Θείας Κωμωδίας, ο σκοπός εδώ είναι να συσχετιστεί η δαντική εκδοχή με το προηγούμενο μυθολογικό και λογοτεχνικό ρεπερτόριο καθώς με τον προσωπικό προβληματισμό του ποιητή και το φιλοσοφικό στοχασμό της εποχής του. Στη συνέχεια διεξήχθη μια λεπτομερής έρευνα της ιταλικής λογοτεχνίας, για να διαπιστωθεί σε ποιά απ'αυτά εμφανίζεται η φιγούρα του Οδυσσέα συνεχίζει αδιάλειπτα να εμφανίζεται στην καλλιτεχνική παραγωγή όλων των αιώνων, φυσικά στο πλαίσιο των κοινωνικών και καλλιτεχνικών συμφραζομένων που επιβάλλουν κάθε φορά οι απαιτήσεις των καιρών
description: Object of the present research was the myth of Ulysses that, in the past centuries, was interpreted with different ways according to the historical moment and the philosophical, political and cultural ideals of every civilization. We have attended the evolution of this myth through the different phases of the History of Italian Literature emphasizing Ulysses as prototype of the traveller and his "last travel", which in Italian Literature is presented more often as direction to "somewhere else", almost in contrast with the "Νοστος" of Homer. The first part of the present work was dedicated to Ulysses as he is presented in the 26th century of Inferno in Dante's Divine Comedy, having as starting point the problematic throughts of the poet and the philosophical worries of his time. We have also been a detailed research in the works of Italian Literature which present the figure of Ulysses and in particular his last travel. Therefore we showed that the Greek hero appears constantly in the artistic production of every century with the suitable adaptation, of course, due to the necessitation of each era

description: Following the Occam's razor principle, we explore the particular textures (featuring texture zeros and equalities) of the Dirac neutrino mass matrix in the minimal seesaw model (where only two right-handed neutrinos $N^{}_1$ and $N^{}_2$ are responsible for the generation of the light neutrino masses), in light of current neutrino experimental results and leptogenesis. The study will be performed for two particular patterns of the Majorana mass matrix $M^{}_{\rm R}$ for $N^{}_1$ and $N^{}_2$: (A) $M^{}_{\rm R}$ being diagonal $ \left( \begin{array}{cc} M^{}_1 & 0 \cr 0 & M^{}_2 \cr \end{array} \right)$; (B) $M^{}_{\rm R}$ being of the form $\left( \begin{array}{cc} 0 & M \cr M & 0 \cr \end{array} \right)$.

Molecular Gas and Star Formation in the SAURON Early-type Galaxies

description: We present the results of a survey of CO emission in 43 of the 48 representative E/S0 galaxies observed in the optical with the SAURON integral-field spectrograph. The CO detection rate is 12/43 or 28%. This is lower than previous studies of early-types but can probably be attributed to different sample selection criteria. As expected, earlier type, more luminous and massive galaxies have a relatively lower molecular gas content. We find that CO-rich galaxies tend to have higher Hβbut lower Fe5015 and Mgb absorption indices than CO-poor galaxies. Those trends appear primarily driven by the age of the stars, an hypothesis supported by the fact that the galaxies with the strongest evidence of star formation are also the most CO-rich. In fact, the early-type galaxies from the current sample appear to extend the well-known correlations between FIR luminosity, dust mass and molecular mass of other galaxy types. The star formation interpretation is also consistent with the SAURON galaxies' radio continuum and FIR flux ratios, and their inferred star formation efficiencies are similar to those in spiral galaxies. It thus appears that we have identified the material fueling (residual) star formation in early-type galaxies, and have demonstrated that it is actively being transformed. Nevertheless, the lack of strong correlations between the CO content and most stellar parameters is compatible with the idea that, in a significant number of sample galaxies, the molecular gas has been accreted from the outside and has properties rather independent from the old, pre-existing stellar component.

description: The tensile force along a cylindrical lipid bilayer tube is proportional to the membrane's bending modulus and inversely proportional to the tube radius. We show that this relation, which is experimentally exploited to measure bending rigidities, can be applied with even greater ease in computer simulations. Using a coarse-grained bilayer model we efficiently obtain bending rigidities that compare very well with complementary measurements based on an analysis of thermal undulation modes. We furthermore illustrate that no deviations from simple quadratic continuum theory occur up to a radius of curvature comparable to the bilayer thickness.
