description: Το πρόβλημα της υπογονιμότητας των ζευγαριών, το οποίο απασχολούσε την κοινωνία από πολύ παλιά με αναφορά περιστατικών τόσο στην αρχαία ελληνική ιστορία και μυθολογία, όσο και στην Παλαιά Διαθήκη, αποτελεί φαινόμενο, η συχνότητα του οποίου έχει αυξηθεί αλματωδώς τις τελευταίες δεκαετίες. Λύση στο σημαντικότατο αυτό πρόβλημα δίνουν σήμερα οι επιστήμες της ιατρικής και της βιολογίας, μέσω ενός ιδιαίτερου τομέα της γυναικολογίας, αυτόν της ιατρικώς υποβοηθούμενης αναπαραγωγής. Η παρένθετη μητρότητα που είναι και το αντικείμενο της παρούσας εργασίας, αποτελεί μία από τις μεθόδους της υποβοηθούμενης αναπαραγωγής. Στο πρώτο κομμάτι της εργασίας γίνεται λόγος για το νομοθετικό πλαίσιο της παρένθετης μητρότητας, τις γενικές και ειδικές προϋποθέσεις εφαρμογής της, ενώ στο δεύτερο κομμάτι γίνεται αναφορά σε ιδιαίτερες προβληματικές που προκύπτουν από την εφαρμογή της παρένθετης μητρότητας στην πράξη. Ειδικότερα, οι προβληματικές αφορούν θέματα που έχουν απασχολήσει τα μέρη κατά τη σύναψη της συμφωνίας παρένθετης μητρότητας, όπως είναι οι ρήτρες που τίθενται από την πλευρά τους, το περιεχόμενο, το κύρος και οι υποχρεώσεις των μερών σε περίπτωση παραβίασής τους, το πρόβλημα της τεχνητής διακοπής της κύησης από την πλευρά τόσο της παρένθετης μητέρας, όσο και της κοινωνικής μητέρας, το επιτρεπτό ή μη της λύσης της σύμβασης παρένθετης μητρότητας, καθώς επίσης η προβληματική της ένταξης των ομόφυλων ζευγαριών στη μέθοδο της παρένθετης μητρότητας.
description: The problem of infertility of couples, which concerns societies since ancient times, as such cases are reported both in ancient greek history and mythology, as well as in the Old Testament, is a phenomenon, the frequency of which has dramatically increased over the past decades. Solution to this major problem give today the sciences of medicine and biology, through a particular field of gynecology, that of medically assisted reproduction. Surrogacy, which is the subject of this paper, is one of the methods of assisted reproduction. The first section of the paper refers to the legal framework of surrogacy, the general and special conditions of its application, while the second section refers to special problematics arising from the application of surrogacy in practice. These problematics regard particularly issues that concern contracting parties at the conclusion of a surrogacy arrangement, such as clauses imposed by their side, their content, their prestige and the obligations of the parties in case these clauses are breached, the problem of artificial interruption of pregnancy from the side of both the surrogate mother, as from the perspective of social mother, the permissible or not of the termination of a surrogacy contract, as well as the problematic of inclusion of gay couples to surrogacy methods.

Με άλλα λόγια μελετήθηκε ο βαθμός, στον οποίο επηρέασε η διεθνής σκηνή τις βουλγαρικές κινήσεις, με γνώμονα πάντοτε τη βουλγαρική στοχοθεσία. Όσον αφορά αυτή τη στοχοθεσία, από την έρευνα προκύπτει πως ήταν διττή. Αναθεωρητισμός μεν, αλλά και επιθυμία για διατήρηση του καθεστώτος της ουδετερότητας και της ειρήνης από την άλλη. Ακόμη, εξετάσθηκε ο τρόπος, με τον οποίο η Βουλγαρία προσπάθησε να ισορροπήσει μεταξύ των γερμανικών και των σοβιετικών πιέσεων, προκειμένου να παραμείνει σε καθεστώς ουδετερότητας. Τέλος, η έρευνα κατέδειξε τις εκατέρωθεν διεθνείς πολιτικές, στρατιωτικές και οικονομικές πιέσεις που δέχτηκε η χώρα, οι οποίες από κοινού με την αναθεωρητική της διάθεση υπαγόρευσαν την τελική της επιλογή
description: The aim of the dissertation was the study of Bulgarian politicy during the last six months of her neutrality. The study is about the way that Bulgaria reacted on Great Powers’ actions. Bulgaria’s ethnic revisionist goals and the will of staying neutral did play jointly an important role on the country’s effort to vacillate between Axis and the Soviet Union. Finally, the dissertation shows the political, financial and military coercion that the country had from both sides, facts that in common with her willingness of national aspiration’s competence, drove her to the Axis side
Possible links between the liquid-gas and deconfinement-hadronization phase transitions

description: It is commonly accepted that strongly interacting matter has several phase transitions in different domains of temperature and baryon density. In this contribution I discuss two most popular phase transitions which in principle can be accessed in nuclear collisions. One of them, the liquid-gas phase transition, is well established theoretically and studied experimentally in nuclear multifragmentation reactions at intermediate energies. The other one, the deconfinement-hadronization phase transition, is at the focus of present and future experimental studies with relativistic heavy-ion beams at SPS, RHIC and LHC. Pssible links between these two phase transitions are identified from the viewpoint of their manifestation in violent nuclear collisions.

Extended Weak Coupling Limit for Friedrichs Hamiltonians

description: We study a class of self-adjoint operators defined on the direct sum of two Hilbert spaces: a finite dimensional one called sometimes a ``small subsystem'' and an infinite dimensional one -- a ``reservoir''. The operator, which we call a ``Friedrichs Hamiltonian'', has a small coupling constant in front of its off-diagonal term. It is well known that under some conditions in the weak coupling limit the appropriately rescaled evolution in the interaction picture converges to a contractive semigroup when restricted to the subsystem. We show that in this model, the properly renormalized and rescaled evolution converges on the whole space to a new unitary evolution, which is a dilation of the above mentioned semigroup. Similar results have been studied before \cite{AFL} in more complicated models and they are usually referred to as "stochastic Limit".

Multiple-Identity Image Attacks Against Face-based Identity Verification

description: Facial verification systems are vulnerable to poisoning attacks that make use of multiple-identity images (MIIs)— face images stored in a database that resemble multiple persons, such that novel images of any of the constituent persons are verified as matching the identity of the MII. Research on this mode of attack has focused on defence by detection, with no explanation as to why the vulnerability exists. New quantitative results are presented that support an explanation in terms of the geometry of the representations spaces used by the verification systems. In the spherical geometry of those spaces, the angular distance distributions of matching and non-matching pairs of face representations are only modestly separated, approximately centred at 90 and 40-60 degrees, respectively. This is sufficient for open-set verification on normal data but provides an opportunity for MII attacks. Our analysis considers ideal MII algorithms, demonstrating that, if realisable, they would deliver faces roughly 45 degrees from their constituent faces, thus classed as matching them. We study the performance of three methods for MII generation—gallery search, image space morphing, and representation space inversion—and show that the latter two realise the ideal well enough to produce effective attacks, while the former could succeed but only with an implausibly large gallery to search. Gallery search and inversion MIIs depend on having access to a facial comparator, for optimisation, but our results show that these attacks can still be effective when attacking disparate comparators, thus securing a deployed comparator is an insufficient defence.
Delayed muscle soreness, muscle function and evidence of leukocytes in human skeletal muscle following eccentric exercise
Creators: name: MacIntyre, Donna Lee
Publisher: name: University of British Columbia
Year: 2009

description: The three primary purposes of these studies were to 1) characterize the time course and the relationships among delayed onset muscle soreness, eccentric muscle torque, serum creatine phosphokinase and urinary hydroxyproline in response to two exercise durations; 2) to examine whether there was increased presence of leukocytes in the exercised muscle compared to the contra-lateral non-exercised muscle; and 3) to determine the time course and the relationships among eccentric muscle torque, muscle fatigue, range of motion, the presence of leukocytes, and delayed onset muscle soreness following the eccentric exercise. In the first study, the dependent variables were measured before and after 180 (shorter duration) and 300 (longer duration) eccentric repetitions of the quadriceps muscles. Eccentric torque of the quadriceps muscles was evaluated utilizing the same parameters of range of motion and velocity of movement as the exercise stimulus. Muscle soreness was evaluated by the Descriptor Differential Scale which reflects the sensory (intensity of soreness) and affective (unpleasantness) components of the discomfort. In the second study, a radionuclide technique was used to determine the presence of leukocytes in the exercised muscle. Muscle fatigue was assessed with a power spectrum analysis. The greatest intensity of soreness and unpleasantness was between 20 and 48 hours postexercise. The presence of leukocytes in the exercised muscle was significantly greater than in the contra-lateral non-exercised muscle. Additional data collection before 24 hours post exercise revealed a biphasic response in eccentric torque, not reported previously in humans. Eccentric torque declined immediately after the exercise stimulus and again at 20 to 24 hours post-exercise. Fatigue of the vastus lateralis muscle was most evident at 2 hours post-exercise. The greatest loss of range of motion occurred at 24 hours post exercise. Significant correlations were found between unpleasantness and creatine phosphokinase, intensity of soreness and creatine phosphokinase, and unpleasantness and range of motion. Using a radionuclide imaging technique allowed a quantitative evaluation of the widespread distribution of the leukocytes compared to the smaller sample that would have been evaluated from microscopic examination of human muscle biopsies. Previously only focal injury has been shown due to the sampling limitations of using isolated muscle biopsies.

description: We give an assessment of the three approaches, undertaken by the D$\emptyset$ experiment, to probe CP violation in $B_s$ mixing without measurement of $B_s$-$\bar B_s$ oscillations or tagging: dimuon charge asymmetry $A_{SL}$, untagged single muon charge asymmetry $A_{SL}^s$, and lifetime difference in untagged $B_s \to J/ψϕ$ decay. The latter two approaches provide an alternative avenue, if not crosscheck, to the usual mixing-decay interference study in modes such as $B_s \to J/ψϕ$. Prospects at the Tevatron, LHC and (Super) B factories are discussed.

Επίσης να τονιστεί πως κυρίαρχο στοιχείο στις Διηγήσεις είναι η πίστη πως αιτία των δεινών των κατοίκων της πόλης που αποτελούν θεϊκές δοκιμασίες – τιμωρίες, είναι οι αμαρτίες των κατοίκων της.
description: The purpose of this work is the historical investigation of Narrations. Through the Narrations valuable information will be drawn, recorded and used in order to bring about unknown aspects of the history of the city concerning the administrative organisation, social, religious and economic life in the city at the end of the 6th and the 7th to the century. The following theological investigation aims to stress that according to the authors of the Narrations the performance of miracles of a Saint is due to the grace that was given to him by God. It should be also noted that the dominant element of the Narrations is faith and the cause of people’s suffering from divine-punishments is due to the sins of inhabitants.

description: We present the results of a 9.3 square degree infrared (ZYJHK) survey in the Upper Scorpius association extracted from the UKIRT Infrared Deep Sky Survey (UKIDSS) Galactic Cluster Survey Early Data Release. We have selected a total of 112 candidates from the ($Z-J$,$Z$) colour-magnitude diagram over the Z=12.5-20.5 magnitude range, corresponding to M = 0.25-0.01 Msun at an age of 5 Myr and a distance of 145 pc. Additional photometry in J and K filters revealed most of them as reddened stars, leaving 32 possible members. Among them, 15 have proper motion consistent with higher mass members from Hipparcos and optical spectra with strong Halpha in emission and weak gravity features. We have also extracted two lower mass candidate members for which no optical spectra are in hand. Three members exhibit strong Halpha equivalent widths (>20 Angstroms), suggesting that they could still undergo accretion whereas two other dwarfs show signs of chromospheric activity. The likelihood of the binarity of a couple of new stellar and substellar members is discussed as well.

description: Learning to localize actions in long, cluttered, and untrimmed videos is a hard task, that in the literature has typically been addressed assuming the availability of large amounts of annotated training samples for each class -- either in a fully-supervised setting, where action boundaries are known, or in a weakly-supervised setting, where only class labels are known for each video. In this paper, we go a step further and show that it is possible to learn to localize actions in untrimmed videos when a) only one/few trimmed examples of the target action are available at test time, and b) when a large collection of videos with only class label annotation (some trimmed and some weakly annotated untrimmed ones) are available for training; with no overlap between the classes used during training and testing. To do so, we propose a network that learns to estimate Temporal Similarity Matrices (TSMs) that model a fine-grained similarity pattern between pairs of videos (trimmed or untrimmed), and uses them to generate Temporal Class Activation Maps (TCAMs) for seen or unseen classes. The TCAMs serve as temporal attention mechanisms to extract video-level representations of untrimmed videos, and to temporally localize actions at test time. To the best of our knowledge, we are the first to propose a weakly-supervised, one/few-shot action localization network that can be trained in an end-to-end fashion. Experimental results on THUMOS14 and ActivityNet1.2 datasets, show that our method achieves performance comparable or better to state-of-the-art fully-supervised, few-shot learning methods.

description: Using a nonlinear Schrödinger equation including short-range two-body attraction and three-body repulsion, we investigate the spatial distribution of indirect excitons in semiconductor coupled quantum wells. The results obtained can interpret the experimental phenomenon that annular exciton cloud first contracts then expands when the number of confined excitons is increased in impurity potential well, as observed by Lai \emph{et al.} [Lai $et al.$, Science \textbf{303}, 503 (2004)]. In particular, the model reconciles the patterns of exciton rings reported by Butov \emph{et al.} [Butov $et al.$, Nature \textbf{418}, 751 (2002)]. At higher densities, the model predicts much richer patterns, which could be tested by future experiments.

Παράλληλα, αναδύονται νέες μορφές ενημέρωσης και εναλλακτικές μέθοδοι επικοινωνίας. Το φαινόμενο δεν είναι ελληνικό, αλλά διεθνές και αντανακλά τις συνέπειες της τεχνολογικής εξέλιξης. Τα ηλεκτρονικά μέσα και ιδίως η έλευση και κυριαρχία του διαδικτύου, έχουν παραμερίσει τα παραδοσιακά μέσα ενημέρωσης. Η πορεία των ΜΜΕ στην Ελλάδα είναι δύσβατη και επηρεάζεται από συστοιχία παραγόντων, αλληλένδετων ή μη μεταξύ τους. Τα παραδοσιακά μέσα είναι αντιμέτωπα με ποικίλες προκλήσεις. Οι κυκλοφορίες των εφημερίδων καταρρέουν και τα τηλεοπτικά δελτία ειδήσεων παρακολουθούνται από όλο και λιγότερους τηλεθεατές. Το τελευταίο στάδιο της παρακμής αποτελεί η κρίση χρέους που προσέβαλε τα ΜΜΕ και κυρίως τις εφημερίδες τα τελευταία χρόνια. Χαρακτηριστικό παράδειγμα αποτελεί ο Δημοσιογραφικός Οργανισμός Λαμπράκη, με την προαναγγελία κλεισίματος όλων των δραστηριοτήτων του, έντυπων και ηλεκτρονικών.

Επομένως, οι επικοινωνιακοί χώροι οφείλουν να εξελιχθούν στο πέρασμα του χρόνου και να προσαρμοστούν στις μεταβαλλόμενες συνθήκες, που αναπόφευκτα επιφέρει η ιστορική εξέλιξη.

description: Nowadays, it is a fact that a truly cosmogenic change in the field of communication is taking place, traditional media are crowding out and leading to decline. At the same time, new forms of information and alternative methods of communication emerge. The phenomenon is not Greek but international and reflects the consequences of technological development. Electronic means, and in particular the advent and dominance of the internet, have left the traditional media. The course of media in Greece is incoherent and is affected by an array of factors, interdependent or unrelated to each other. Traditional media are faced with a variety of challenges. Newspapers' releases collapse and TV newscasts are being watched by fewer viewers. The final stage of the decline is the debt crisis that has plagued the media and especially the newspapers in recent years. A typical example is the Lambrakis Press, announcing the closure of all its activities, printed and electronic. We are now experiencing the end of information as we know it and the transition to another era. Therefore, communication spaces must evolve over time and adapt to the changing circumstances that inevitably bring about historical development. In addition, the need for a visionary and at the same time coherent national strategy in the communication field is vital.

description: We evaluate nucleon four-point functions in the framework of lattice QCD in order to extract the first Mellin moment of double parton distributions (DPDs) in the unpolarized proton. In this first study, we employ an nf = 2 + 1 ensemble with pseudoscalar masses of mpi = 355 MeV and mK = 441 MeV. The results are converted to the scale mu = 2 GeV. Our calculation includes all Wick contractions, and for almost all of them a good statistical signal is obtained. We analyze the dependence of the DPD Mellin moments on the quark flavor and the quark polarization. Furthermore, the validity of frequently used factorization assumptions is investigated.

description: Sedimentation-diffusion equilibrium density profiles of suspensions of charge-stabilized colloids are calculated theoretically and by Monte Carlo simulation, both for a one-component model of colloidal particles interacting through pairwise screened-Coulomb repulsions and for a three-component model of colloids, cations, and anions with unscreened-Coulomb interactions. We focus on a state point for which experimental measurements are available [C.P. Royall et al., J. Phys.: Cond. Matt. {\bf 17}, 2315 (2005)]. Despite the apparently different picture that emerges from the one- and three-component model (repelling colloids pushing each other to high altitude in the former, versus a self-generated electric field that pushes the colloids up in the latter), we find similar colloidal density profiles for both models from theory as well as simulation, thereby suggesting that these pictures represent different view points of the same phenomenon. The sedimentation profiles obtained from an effective one-component model by MC simulations and theory, together with MC simulations of the multi-component primitive model are consistent among themselves, but differ quantitatively from the results of a theoretical multi-component description at the Poisson-Boltzmann level. We find that for small and moderate colloid charge the Poisson-Boltzmann theory gives profiles in excellent agreement with the effective one-component theory if a smaller effective charge is used. We attribute this discrepancy to the poor treatment of correlations in the Poisson-Boltzmann theory.

description: This current thesis discusses the generalized linear models. At first, an introduction of generalized linear models is provided and a consideration of the general structure and range of applications of generalized linear models is presented. Afterwards, in greater detail generalized linear models for count data are examined, including contingency tables. Furthermore, the statistical theory underlying generalized linear model is described and the diagnostics of generalized linear models are studied. Ultimately, an application is carried out on meteorological data with the statistical package R.

description: Interfacing magnetism with superconducting condensates is rapidly emerging as a viable route for the development of innovative quantum technologies. In this context, the development of rational design strategies to controllably tune the interaction between magnetic moments is crucial. In the metallic regime, the indirect interaction mediated by conduction electrons, the so-called RKKY coupling, has been proven to be remarkably fertile in creating and controlling magnetic phenomena. However, despite its potential, the possibility of using superconductivity to control the sign and the strength of indirect interactions between magnet moments remains largely unexplored. Here we address this problem at its ultimate limit, demonstrating the possibility of maximally tuning the interaction between local spins coupled through a superconducting condensate with atomic scale precision. By using Cr atoms coupled to superconducting Nb as a prototypical system, we use atomic manipulation techniques to precisely control the relative distance between local spins along different crystallographic directions while simultaneously sensing their coupling by scanning tunneling spectroscopy. Our results reveal the existence of highly anisotropic superconductor-mediated indirect couplings between the local spins, lasting up to very long distances, up to 12 times the lattice constant of Nb. Moreover, we demonstrate the possibility of controllably crossing a quantum phase transition by acting on the direction and interatomic distance between spins. The extremely high tunability provides novel opportunities for the realization of exotic phenomena such as topological superconductivity and the rational design of magneto-superconducting interfaces.

description: We investigate the achievable rate of data transmission from sources to sinks through a multiple-relay network. We study achievable rates for omniscient coding, in which all nodes are considered in the coding design at each node. We find that, when maximizing the achievable rate, not all nodes need to ``cooperate'' with all other nodes in terms of coding and decoding. This leads us to suggest a constrained network, whereby each node only considers a few neighboring nodes during encoding and decoding. We term this myopic coding and calculate achievable rates for myopic coding. We show by examples that, when nodes transmit at low SNR, these rates are close to that achievable by omniscient coding, when the network is unconstrained . This suggests that a myopic view of the network might be as good as a global view. In addition, myopic coding has the practical advantage of being more robust to topology changes. It also mitigates the high computational complexity and large buffer/memory requirements of omniscient coding schemes.

Wife assault, patterns of male attachment and intimate conflict behaviours: a study of fifty men
Creators: name: Saunders, Keith Donald
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this preliminary and exploratory research project was to identify possible links between insecure male attachment patterns and wife assault. Attachment theory suggests that the quality of early interpersonal relationships has a profound effect on the psychological, emotional and social development of the individual. Insecure attachment has been found to be associated with a number of relationship problems and these interpersonal problems have also been identified with men who assault their wives. Based on this similarity, the insecure attachment paradigm may offer a useful theoretical orientation for understanding the conflict behaviours of men who assault their wives. The sample of fifty adult men who had assaulted their female partners was drawn from two therapy groups. In this preliminary and exploratory study, a number of measures were used to assess each man's mental representation of childhood attachment and his adult intimate attachment patterns, intimate conflict tactics and interpersonal jealousy and anger problems. The associations between insecure preoccupied, dismissing, and fearful attachment pattern ratings and male conflict tactic and relationship problems were then analyzed. The findings indicated that men who assault their wives had a high proportion of insecure adult intimate attachment patterns. These assaultive men were also found to be predominantly insecure in both their mental representations of childhood attachment and adult intimate attachment pattern ratings, with the greatest continuity occurring with the insecure preoccupied and fearful pattern ratings. Three patterns of relationship problems corresponding to the three insecure adult intimate attachment pattern rating were found. Preoccupied attachment pattern ratings were positively correlated with interpersonal jealousy scores and the reported use of the reasoning, verbal/symbolic abuse, physical abuse and severe physical abuse conflict tactics. Dismissing attachment pattern ratings were positively correlated with interpersonal anger scores and negatively correlated with the reasoning, verbal, physical and severe physical abuse conflict tactics. Fearful attachment pattern ratings were similar to the dismissing pattern in the positive correlation with interpersonal anger scores. The importance of considering insecure adult intimate attachment pattern ratings when providing group therapy to men who assault their wives was considered. Men with high insecure dismissing adult intimate attachment pattern ratings seem to require a distinctly different therapeutic approach than those with high insecure preoccupied adult intimate attachment pattern ratings and ideas in this regard are discussed.

description: Τα χνάρια της πρόσφατης ελληνικής πολιτικής ιστορίας είναι έντονα αποτυπωμένα στον τύπο. Ο τύπος διαδραμάτισε και συνεχίζει να διαδραματίζει σπουδαίο ρόλο. Η δύναμη αυτή του τύπου έγινε, ταχύτατα αντιληπτή, όχι μόνο από τους υποστηρικτές της ελευθερίας του, αλλά και από εκείνους που είχαν συμφέρον από τη χειραγώγησή του. Η δύναμη του τύπου είναι κυριολεκτικά απέραντη, ακαταμέτρητη, ιδίως στον βαθμό που επηρεάζει, καθοδηγεί και διαμορφώνει την κοινή γνώμη. Επιπλέον, αποτελεί το ισχυρότερο όργανο ελέγχου της κρατικής εξουσίας και συντελεί στην αποτροπή των καταχρήσεων αυτής. Συνεπώς, ο ελεύθερος τύπος συνιστά τη σπουδαιότερη προϋπόθεση του δημοκρατικού πολιτεύματος. Η ελευθερία του τύπου δεν αποτελεί πάντα, µια σαφή και δεδομένη συνθήκη. Σε περιόδους κοινωνικών εντάσεων, πολέµων και ανακατατάξεων, αλλά και αυταρχικών και δικτατορικών καθεστώτων, ο τύπος τέθηκε υπό καθεστώς αναγκαστικής λογοκρισίας (δικτατορία του Mεταξά, γερμανική κατοχή, εμφύλιος πόλεμος, Απριλιανή δικτατορία). Στις περιόδους αυτές, κάποιες εφηµερίδες συνέχισαν να τυπώνονται και να κυκλοφορούν, ενώ κάποιες άλλες έκαναν, για πρώτη φορά, την εµφάνισή τους µέσα σε συνθήκες αποκλεισµού και παρανοµίας, ενηµερώνοντας για τη διαφορετική εκδοχή των πραγµάτων. Στις περιόδους της παρανοµίας έγιναν αποκλειστικοί διακινητές πληροφοριών και λογοκριµένων ειδήσεων, αλλά και προπαγανδιστές ιδεών αµφισβήτησης των εκάστοτε αυταρχικών καθεστώτων.
description: The footsteps of recent Greek political history are strongly depicted in the press. The guy has played and continues to play a major role. This type of force was quickly perceived not only by the supporters of his freedom but also by those who had an interest in manipulating it. The power of the press is literally immeasurable, incomparable, particularly to the extent that it influences, guides and shapes public opinion. In addition, it is the most powerful instrument of state authority and helps to prevent such abuses. Consequently, the free press is the most important condition of the democratic system. Freedom of the press is not always a clear and given treaty. In times of social tensions, wars and redeployments, as well as domineering and dictatorial regimes, the press has been subjected to forced censorship (Metaxa dictatorship, German occupation, civil war, April dictatorship). At these times, some newspapers continued to be printed and circulated, while others, for the first time, appeared in conditions of exclusion and illegality, informing about the different version of things. During the periods of illegality, they became exclusive traffickers of censorship and censored news, as well as propagandists of ideas of questioning the authoritarian regimes.

description: In statistical QCD, the thermal properties of the quark-gluon plasma can be determined by studying the in-medium behaviour of heavy quark bound states. The results can be applied to quarkonium production in high energy nuclear collisions, if these indeed form a fully equilibrated QGP. Modifications could arise if an initial charm excess persists in the collision evolution and causes quarkonium regeneration at hadronization.

description: Η ενέργεια είναι απαραίτητη για τη σύγχρονη ζωή. Η αξιόπιστη πρόσβαση στην προσφορά σε ανταγωνιστικές τιμές είναι ζωτικής σημασίας για την ευημερία των πολιτών και για την ανάπτυξη και την ανταγωνιστικότητα της βιομηχανίας της ΕΕ. Εντούτοις, οι αγορές ενέργειας παρουσιάζουν ορισμένα διαρθρωτικά χαρακτηριστικά που θα μπορούσαν να επιτρέψουν στις κατεστημένες επιχειρήσεις να ασκήσουν την ισχύ της αγοράς, γεγονός που περιορίζει τον ανταγωνισμό και ενδεχομένως δημιουργεί υψηλότερες τιμές και μειωμένη φροντίδα των καταναλωτών. Στην παρούσα εργασία σε πρώτο επίπεδο παρουσιάζεται ο τομέας των συγκεντρώσεων επιχειρήσεων υπό το φως του Ευρωπαϊκού Κανονισμού 139/2004, ο οποίος είναι και αυτός που διέπει τον έλεγχό τους, εφόσον αυτές έχουν κοινοτική διάσταση. Έπειτα εξετάζεται το φαινόμενο των συγκεντρώσεων επιχειρήσεων στον τομέα της αγοράς ενέργειας. Ειδικότερα, καταβάλλεται προσπάθεια να εντοπιστούν οι ιδιαιτερότητες και οι πολυπλοκότητες που διέπουν τον τομέα της ενέργειας και να σκιαγραφηθεί η επίδρασή τους στην τελική διαμόρφωση των συγκεντρώσεων των ενεργειακών επιχειρήσεων. Εν κατακλείδι, γίνεται μια περιγραφή της τρέχουσας κατάστασης και επιχειρείται να προσεγγιστεί και να αξιολογηθεί γενικότερα η επιβολή της πολιτικής ανταγωνισμού της ΕΕ στον τομέα των ενεργειακών συγκεντρώσεων. Ήταν τελικά αποδοτική για τον ανταγωνισμό στις ευρωπαϊκές αγορές φυσικού αερίου και ηλεκτρικής ενέργειας η τακτική αυτή ή όχι; Ποιός ο ρόλος των τιμών του πετρελαίου στο σκηνικό όπως διαμορφώνεται;
description: Energy is essential for modern life. Reliable access to supply at competitive prices is vital to the well-being of citizens and to the development and competitiveness of EU industry. However, energy markets have some structural features that could allow incumbents to exercise their power market, which restricts competition and potentially generates higher prices and reduced consumer care. In the present thesis, at first is presented the sector of business concentrations in the light of European Regulation 139/2004, which also governs their control, since they have a Community dimension. Then is being examined the concentration phenomenon in energy market. In particular, an effort is made to identify the specificities and complexities of the energy sector and to outline their impact on the final formation of energy companies concentrations. In conclusion, we make a description of the current situation and we attempt to make an approach and generally to assess the enforcement of EU competition policy in the field of energy concentrations. Was it finally effective for competition in the European gas and electricity markets this tactic or not? What is the role of oil prices in the setting as it stands?

description: We propose a measurement scheme to directly detect odd-frequency superconductivity via time- and angle-resolved photoelectron fluctuation spectroscopy. The scheme includes two consecutive, non-overlapping probe pulses applied to a superconducting sample. The photoemitted electrons are collected in a momentum-resolved fashion. Correlations between signals with opposite momenta are analyzed. Remarkably, these correlations are directly proportional to the absolute square of the time-ordered anomalous Green's function of the superconductor. This setup allows for the direct detection of the "hidden order parameter" of odd-frequency pairing. We illustrate this general scheme by analyzing the signal for the prototypical case of a two-band superconductor.
