description: This paper presents the role and utility of music in cinema. Reference is made to the relationship between the two arts, from the early cinema until today. Analyze the various uses of music, depending on the needs of the film. The roles and uses of music in film are presented through examples of films for which composer Nikos Kypourgos has written music. Reference is also made to the way in which the composer works on the preparation, of the tools he use and highlighted the key role of existence of music in cinema. At the same time there is a comparison between work of Nikos Kypourgos and the work of his colleagues from the new Greek and international cinema. The work is based on theoretical research, comparison and analysis of texts and reviews of the press, music scores, literature and interviews associated with Nikos Kypourgos and film music.

description: The ubiquitin ribosome fusion gene RpS27a’s coding sequence was cloned from diamondback moth, Plutella xylostella (L.). An open reading frame of 468 bp was found to encode a putative 155 amino acid precursor protein, which shares over 90% similarity with other insects’ RpS27a protein. Real-time quantitative PCR was carried out to determine the relative expression level in the fourth instar larvae of deltamethrin-resistant and deltamethrin-susceptible strains. The results showed that the expression of RpS27a was significantly higher in the deltamethrin-resistant strain than in the deltamethrin-susceptible strain. There are reports indicating that upregulation expression of some ribosomal proteins confers some insecticide resistance. For the first time, we have predicted that the increased expression of the RpS27a gene may have some association with pesticide resistance in Plutella xylostella.

description: We propose an on-chip optical waveguide for Bose-Einstein condensates based on the evanescent light fields created by surface states of a photonic crystal. It is shown that the modal properties of these surface states can be tailored to confine the condensate at distances from the chip surface significantly longer that those that can be reached by using conventional index-contrast guidance. We numerically demonstrate that by index-guiding the surface states through two parallel waveguides, the atomic cloud can be confined in a two-dimensional trap at about 1$μ$m above the structure using a power of 0.1mW.

description: We consider the usual Einstein-Hilbert action in a Metric-Affine setup and in the presence of a Perfect Hyperfluid. In order to decode the role of shear hypermomentum, we impose vanishing spin and dilation parts on the sources and allow only for non-vanishing shear. We then consider an FLRW background and derive the generalized Friedmann equations in the presence of shear hypermomentum. By providing one equation of state among the shear variables we study the cases for which shear has an accelerating/decelerating effect on Universe's expansion. In particular, we see that shear offers a possibility to prevent the initial singularity formation. We also provide some exact solutions in the shear dominated era and discuss the physical significance of the shear current.

description: Supernova neutrino flavor transitions during the shock wave propagation are known to encode relevant information not only about the matter density profile but also about unknown neutrino properties, such as the mass hierarchy (normal or inverted) and the mixing angle theta_13. While previous studies have focussed on "deterministic" density profiles, we investigate the effect of possible stochastic matter density fluctuations in the wake of supernova shock waves. In particular, we study the impact of small-scale fluctuations on the electron (anti)neutrino survival probability, and on the observable spectra of inverse-beta-decay events in future water-Cherenkov detectors. We find that such fluctuations, even with relatively small amplitudes, can have significant damping effects on the flavor transition pattern, and can partly erase the shock-wave imprint on the observable time spectra, especially for sin^2(theta_13) > O(10^-3).

Για το σκοπό αυτό αναλύθηκαν τα απομαγνητοφωνημένα κείμενα της συνεδρίασης της Ολομέλειας του ελληνικού κοινοβουλίου της συζήτησης για το νόμο 4251/2014 με τίτλο «Κώδικας Μετανάστευσης και Κοινωνικής Ένταξης και λοιπές διατάξεις» με βάση τις αρχές της Ρητορικής Ψυχολογίας και της Κριτικής Ανάλυσης Λόγου. Από την ανάλυση προέκυψε ότι η επιχειρηματολογία αρθρώθηκε γύρω από τρεις κύριους θεματικούς άξονες εντός των οποίων αναπτύχθηκαν διαφορετικές ρητορικές κατασκευές. Αυτοί ήταν ο λόγος για την πολυπολιτισμικότητα, η ρητορική «πρώτα οι έλληνες» και η διαπραγμάτευση του ποιος έχει δικαίωμα και υπό ποιους όρους να συμμετέχει στην κοινωνική κατηγορία «έλληνας πολίτης». Στο κεφάλαιο της συζήτησης οι παραπάνω θεματικές συνδέονται με ευρύτερα ζητήματα που αφορούν την ιδιότητα του πολίτη και την κοινωνική ψυχολογία και επιχειρείται μια θεώρησή τους υπό ένα κριτικό κοινωνικοψυχολογικό πρίσμα.
description: The present study explores the rhetorical constructions of citizenship in political discourse on immigration. For this purpose the transcripts of the plenary session of the Greek Parliament on the debate on the law 4251/2014 entitled “Immigration and Social Integration Code and other provisions” were analyzed, based on the principles of, Rhetoric Psychology and Critical Discourse Analysis. The analysis showed that the arguments articulated around three main thematic categories within which different rhetorical categories were constructed . These were i. the discourse on multiculturalism, ii. the rhetoric “Greeks go first” and iii. the negotiation of who has the right and under which conditions to participate in the category of “greek citizen”. The discussion chapter tries to link the above themes to broader issues on citizenship and social psychology and considers them under a critical social psychological perspective. .

description: The aim of this study was the discussion of the mortuary practices and the treatment of the dead that have occurred in the wider region of Greece during the Neolithic period. For this purpose carried out a detailed collection of the available, excavated data and cited with detail the positions that yielded anthropological residues of any kind. The picture that emerges from the discussion and display of the burial customs of the under study period is distinguished by complexity and diversity. There are differences in the choice of deposition, based primarily on age criteria, while the dead remain in direct connection with the world of the living.

description: We describe a transition from bursting to rapid spiking in a reduced mathematical model of a cerebellar Purkinje cell. We perform a slow-fast analysis of the system and find that -- after a saddle node bifurcation of limit cycles -- the full model dynamics follow temporarily a repelling branch of limit cycles. We propose that the system exhibits a dynamical phenomenon new to realistic, biophysical applications: torus canards.

description: “The Philosophy of Strength”: Mussolini reads Nietzsche This chapter deals with Nietzsche’s political thought starting from how it was incorporated by Benito Mussolini, first among others, in his fascist ideology. I will trace the genesis and content of La filosofia della forza (The Philosophy of Strength), a general interpretation of Nietzsche’s thought written by Mussolini in 1908 when he still proclaimed himself a socialist and a Marxist. Particular attention will be given to the markedly proto-fascist tones of this essay and their continuity with subsequent references to Nietzsche, which were formulated during Mussolini’s rise to power and regime. This reconstruction will be accompanied by a deconstruction: I will show how Mussolini’s interpretations were largely based on isolated passages and remixed into arbitrary collages. The increasing exploitation of Nietzsche by the international New Right and, more specifically, the renewed attention dedicated to The Philosophy of Strength by Italian neo-fascists show the urgent need for such deconstructive work. However, if the latter is carried out rigorously – as I argue in the final part of the chapter – it leads to the inconsistency of Nietzsche’s political reflection.

Εξετάσαμε τις κλιματικές συνθήκες που επικρατούσαν κατά τη διάρκεια της εμφάνισης τους στο χώρο της Μέσης Ανατολής, τις παρεχόμενες διατροφικές πηγές, την κατασκευή των αρχιτεκτονημάτων και τη λιθοτεχνία τους. Στη συνέχεια παρουσιάσαμε αναλυτικά τις αρχαιολογικές θέσεις με τα ανθρωπογενή κατάλοιπα τα οποία συγκεντρώθηκαν ως σήμερα. Ακόμη, αναφερθήκαμε στις ομοιότητες και τις διαφορές που εντοπίζονται στις ταφικές πρακτικές των Νατούφιων. . Ένα άλλο θέμα που θίξαμε ήταν η εξέλιξη στο θεωρητικό πλαίσιο των ερευνών και η συμβολή των ιδεών του S. Freud, του C. Jung και του J. Cauvin. Τέλος, ασχοληθήκαμε επιπλέον με τη σημασία που αποδίδουν οι Νατούφιοι στους ενταφιασμούς των νεκρών τους και τα ίχνη και τις όψεις του συμβολισμού.
description: The aim of the present thesis was the study of burial practices in the latest hunters of Levant, the Natufians. Initially we mentioned in the historical context of the research, the geographic range of establishment and the dating of these hunting groups. We examined the climatic conditions prevailing during their appearance in the Middle East, the provided food sources, the construction of architectural structures and their stone industry. Then we presented in detail the archaeological sites with anthropogenic remains gathered today. Furthermore, we discussed the similarities and differences found in the burial practices of Natufians. Another issue we discussed was the development in the theoretical framework of investigations and the contribution of ideas of S. Freud, C. Jung and J. Cauvin. Finally, we dealt with the extra importance that Natufians attached in burials of their dead and the traces and faces of symbolism.

description: This contribution presents a hierarchical multigrid approach for the solution of large-scale finite cell problems on both uniform grids and multi-level hp-discretizations. The proposed scheme leverages the hierarchical nature of the basis functions utilized in the finite cell method and the multi-level hp-method, which is attributed to the use of high-order integrated Legendre basis functions and overlay meshes, to yield a simple and elegant multigrid scheme. This simplicity is reflected in the fact that all restriction and prolongation operators reduce to binary matrices that do not need to be explicitly constructed. The coarse spaces are constructed over the different polynomial orders and refinement levels of the immersed discretization. Elementwise and patchwise additive Schwarz smoothing techniques are used to mitigate the influence of the cut cells leading to convergence rates that are independent of the cut configuration, mesh size and in certain scenarios even the polynomial order. The multigrid approach is applied to second-order problems arising from the Poisson equation and linear elasticity. A series of numerical examples demonstrate the applicability of the scheme for solving large immersed systems with multiple millions and even billions of unknowns on massively parallel machines.

description: We discuss a constant contribution to meson correlators at finite temperature. In the deconfinement phase of QCD, a colored single quark state is allowed as a finite energy state, which yields to a contribution of wraparound quark propagation to temporal meson correlators. We investigate the effects in the free quark case and quenched QCD at finite temperature. The ``scattering'' contribution causes a constant mode in meson correlators with zero spatial momentum and degenerate quark masses, which can dominate the correlators in the region of large imaginary times. In the free spectral function, the contribution yields a term proportional to $ωδ(ω)$. Therefore this contribution is related to transport phenomena in the quark gluon plasma. It is possible to distinguish the constant contribution from the other part using several analysis methods proposed in this paper. As a result of the analyses, we find that drastic changes in charmonium correlators for $χ_c$ states just above the deconfinement transition are due to the constant contribution. The other differences in the $χ_c$ states are small. It may indicate the survival of $χ_c$ states after the deconfinement transition until, at least, $1.4T_c$.

Optimum fertilization of hybrid poplar plantations in coastal British Columbia
Creators: name: Zabek, Lisa M.
Publisher: name: University of British Columbia
Year: 2009

description: The principles of optimum nutrition were examined in a short-rotation intensive-culture (SRIC) hybrid poplar plantation near Sayward, B.C. One-year-old SRIC hybrid poplar (Populus trichocarpa x P. deltoides) were fertilized with N or NPK applied once, in 3 equal additions, or in 3 incremental additions. Total loading rates were 225 kg N/ha, 75 kg P/ha and 75 kg K/ha. Height and diameter growth increased after fertilization, with NPK generally providing the best response after two growing seasons. Application timing did not affect growth. Two-year-old hybrid poplar were fertilized with N , NP, NPK or NPKS. Total loading rates were 225 kg N/ha, 75 kg P/ha, 75 kg K/ha and 15 kg S/ha. Height and diameter growth were highest after one growing season in trees fertilized with NPKS. One-month-old poplar stecklings were fertilized with 5 nutrient combinations (N, NK, NP, NKP or NKPCaMg) at 4 rates (0, 150, 300 or 450 kg N/ha). Loadings were based on 100N:70K: 13P:7Ca:7Mg. Biomass, leaf area and foliar nutrient concentrations were measured after 17 weeks. Foliar nutrient concentrations and contents increased after fertilization. Additional nutrients, in combination with N , increased steckling biomass, but application rate did not. Growth responses to 5 organic wastes and NPK fertilizer were compared in a second pot bioassay. Biomass, leaf area and foliar nutrient concentrations were measured after 17 weeks. The greatest growth response was to organic wastes, particularly fish-wood compost. Application of these results to SRIC hybrid poplar nutrition are discussed.

description: Background

The common bile duct cyst is a congenital dilatation of the bile duct, cysts with a diameter greater than 10 cm are considered giant cysts, this is a rare condition that represents 1% of benign lesions of the bile duct; its presence varies according to the population studied; it has an incidence of 1/150 000 in western countries and a higher prevalence in the female sex.

We present the case of a giant common bile duct cyst in an adult woman, the clinical picture debuted as jaundice associated with abdominal pain during pregnancy, managed with emergency biliary decompression and definitive surgery programmed with cholecystectomy and resection of the common bile duct cyst together with reconstruction of the biliary tract with hepatojejunal anastomosis.

Keywords: Common bile duct cyst, Giant, Pregnacy.

description: We report a narrowing of the interference pattern obtained in an atomic Ramsey interferometer if the two separated fields have different frequency and their phase difference is controlled. The width of the Ramsey fringes depends inversely on the free flight time of ground state atoms before entering the first field region in addition to the time between the fields. The effect is stable also for atomic wavepackets with initial position and momentum distributions and for realistic mode functions.

description: We consider charge transport properties of 2+1 dimensional conformal field theories at non-zero temperature. For theories with only Abelian U(1) charges, we describe the action of particle-vortex duality on the hydrodynamic-to-collisionless crossover function: this leads to powerful functional constraints for self-dual theories. For the n=8 supersymmetric, SU(N) Yang-Mills theory at the conformal fixed point, exact hydrodynamic-to-collisionless crossover functions of the SO(8) R-currents can be obtained in the large N limit by applying the AdS/CFT correspondence to M-theory. In the gravity theory, fluctuating currents are mapped to fluctuating gauge fields in the background of a black hole in 3+1 dimensional anti-de Sitter space. The electromagnetic self-duality of the 3+1 dimensional theory implies that the correlators of the R-currents obey a functional constraint similar to that found from particle-vortex duality in 2+1 dimensional Abelian theories. Thus the 2+1 dimensional, superconformal Yang Mills theory obeys a "holographic self duality" in the large N limit, and perhaps more generally.

description: Malware detection has become a challenging task due to the increase in the number of malware families. Universal malware detection algorithms that can detect all the malware families are needed to make the whole process feasible. However, the more universal an algorithm is, the higher number of feature dimensions it needs to work with, and that inevitably causes the emerging problem of Curse of Dimensionality (CoD). Besides, it is also difficult to make this solution work due to the real-time behavior of malware analysis. In this paper, we address this problem and aim to propose a feature selection based malware detection algorithm using an evolutionary algorithm that is referred to as Artificial Bee Colony (ABC). The proposed algorithm enables researchers to decrease the feature dimension and as a result, boost the process of malware detection. The experimental results reveal that the proposed method outperforms the state-of-the-art.

description: The compressive strain induced work function modulation in boron nitride nanosheets (BNNS) has been studied. The compressive strain arose due to the irradiation of 30 keV Au beam on thin films of BNNS. Before irradiation BNNS was characterized by Raman spectroscopy, UV-Vis spectroscopy, where using Tauc plot the bandgap of chemically synthesized BNNS from commercial hBN powder has been calculated as well as the layer numbers on thin films also quantified using an empirical relation exploiting the full width at half maxima (FWHM) of Raman peak of BNNS. The Scanning Electron Microscopy (SEM) images were also taken where layer like structure in pristine BNNS sample is visible and irradiation-induced changes in terms of irregular dots on BNNS samples is witnessed. The X-Ray Diffraction (XRD) was used to characterize the BNNS samples where peak corresponding to (002) plane is depicted as well as the peak shifting to higher angle which indicates the compressive strain in BNNS is also visible. Finally, the possible explanation of compressive strain formation by Au irradiation on BNNS was discussed using SRIM-2013 MC simulations. We've explained that vacancy induces strain in materials that lower the work function (WF). Scanning Kelvin Probe Microscopy (SKPM) was used to map the work function of the surface of BNNS, and it turned out that WF lowers with increasing dose of ions. The value of strain also calculated using the work function values and the results are qualitatively agreeing with the XRD results.

description: Δύο είδη εμφυτευμάτων ισχίου με διαφορετική γεωμετρία και μέγεθος για διάφορα υλικά, αξιολογήθηκαν σε πεδίο ραδιοσυχνοτήτων σε περιβάλλον μαγνητικής τομογραφίας για το πόσο θερμαίνονται. Γενικά, διαφορετικές διαστάσεις, σχήματα και υλικά προκαλούν διαφορετικές αυξήσεις της θερμοκρασίας. Τα εμφυτεύματα για 6 διαφορετικές περιπτώσεις υλικών τοποθετήθηκαν 2cm κοντά στα πλευρικά τοιχώματα του ομοιώματος ASTM F2182-09. Το ομοίωμα τοποθετείται παράλληλα στο z-άξονα μέσα σε ένα καλά σχεδιασμένο και συντονισμένο MRI birdcage πηνίο σε 1.5T/64MHz. Η κατανομή του ηλεκτρικού πεδίου, το μέγιστο ηλεκτρικό πεδίο, ο μέγιστος SAR1g και τα δινορεύματα εκτιμήθηκαν στην ηλεκτρομαγνητική ανάλυση. Η αύξηση της θερμοκρασίας υπολογίστηκε σε 8 θέσεις του κάθε εμφυτεύματος. Οι τιμές κανονικοποιήθηκαν στο όριο ασφαλείας SARwb=2W/kg κατά το πρότυπο IEC 60601-2-33. Στις θερμικές προσομοιώσεις επιλύθηκε η εξίσωση μεταφοράς θερμότητας Οι θερμοκρασίες καταγράφηκαν για 20 min. έκθεσης. Οι προσομοιώσεις δημιουργήθηκαν και εκτελέστηκαν στο λογισμικό SEMCAD X v.14.8 (SPEAG, Zurich). Ο σκοπός είναι η μελέτη της εξάρτησης της θερμοκρασίας από τις διαστάσεις, τη γεωμετρία και το υλικό των εμφυτευμάτων και η ανάπτυξη μοντέλων λιγότερο ευαίσθητων σε ραδιοσυχνοτική θέρμανση σύμφωνα με τα πρωτόκολλα ασφαλείας. Αναμένεται ότι τα αποτελέσματα της αριθμητικής προσομοίωσης μπορούν να ενισχύσουν την κατανόηση των αλληλεπιδράσεων των ιατρικών εμφυτεύματων με την μαγνητική τομογραφία.
description: Two types of hip implants with different geometry and size for various materials were evaluated in RF field in MRI environment of how they were heated. Generally, different dimensions, shapes and materials cause different temperature increases. Implants for six different material cases placed 2cm near the sidewalls of the ASTM F2182-09 phantom. ASTM phantom placed parallel to the z-axis in a well designed and resonated MRI birdcage coil at 1.5T/64MHz. The electric field’s distribution, the maximum electric field, the Peak Average SAR1g and eddy currents were estimated in electromagnetic analysis. Maxwell’s equations solved with FDTD method. The temperature increase calculated at 8 positions of each implant. The heat transfer equation solved for thermal equations. The values were normalized to the safety limit of SARwb = 2W/kg according to IEC 60601-2-33 standard. Temperatures were recorded for 20 min. exposure. Simulations were created and executed in software SEMCAD X v.14.8 (SPEAG, Zurich). The purpose is to study the temperature dependence from dimensions, geometry and material of the implants and the development of models less sensitive to RF heating according to safety protocols. It is expected that the results of numerical simulations can enhance the understanding of the interactions of medical implants with MRI

description: We study the properties of an impurity immersed in a weakly interacting Bose gas, i.e., of a Bose polaron. In the perturbatively-tractable of limit weak impurity-boson interactions many of its properties are known to depend only on the scattering length. Here we demonstrate that for strong (unitary) impurity-boson interactions all static quasiproperties of a Bose polaron in a dilute Bose gas, such as its energy, its residue, its Tan's contact and the number of bosons trapped nearby the impurity, depend on the impurity-boson potential via a single parameter.

Μετά από βιβλιογραφική ανασκόπηση καθορίστηκαν πέντε συναφή με την ΕΚΕ πεδία: πελάτες, κοινωνία, περιβάλλον, εργαζόμενοι, οργάνωση-προγραμματισμός. Η έρευνα επιβεβαίωσε την πολυδιάστατη φύση της ΕΚΕ και επισήμανε ότι η απαιτείται συντονισμένη κινητοποίηση όλων των εμπλεκομένων φορέων για την ολοκληρωμένη ενημέρωση για την ΕΚΕ και τις πρακτικές. Ο ξενοδοχειακός τομέας είναι ευρέως προσανατολισμένος στον πελάτη / επισκέπτη και διατηρεί έναν πολύ ισχυρό δεσμό με το φυσικό περιβάλλον στο οποίο δραστηριοποιείται. Οι πρακτικές αυτές όμως έχουν αποσπασματικό χαρακτήρα, και γενικά στερούνται συστηματικής οργάνωσης και προγραμματισμού καθώς και μεθόδου και εργαλείων παρακολούθησης και ελέγχου αυτών των θεμάτων.
description: The present thesis was a research through a structured questionnaire and aimed to investigate the CSR awareness and the identification of elements which would guide to the development of a CSR tool for the Greek hotel SMEs by focusing in a convenient sample of 102 Greek hotel SMEs. Through a literature review five CSR dimensions were identified: customers, society, environment, employees, organization/programming. The research confirmed the multidimensional nature of CSR and highlighted that a coordinated mobilization of related institutions is required to achieve comprehensive information on CSR issues and its practices. The hotel sector is broadly oriented to customers and maintains a powerful link with the environment in which it is functioning. Nevertheless, these CSR practices have a fragmentary character and they generally lack systematic organization and programming as well as monitor and control methods and tools.

description: In the quadri-dimensional space-time, the variation of Hamilton's action is a powerful tool to study the process equations for conservative fluid media. In this framework, Hamilton's principle allows to obtain equation of motions, equation of energy but also Rankine-Hugoniot conditions. The varia-tional method may be a versatile key to obtain the shock-wave conditions for complex media when the equations of processes are not expressed by linear or quasi-linear differential equations.

description: This paper presents a large spectral line and continuum survey of 8 deeply embedded, low-mass protostellar cores using the Submillimeter Array. Each source was observed in high excitation lines of some of the most common molecular species, CO, HCO+, CS, SO, H2CO, CH3OH and SiO. Line emission from 11 species originating from warm and dense gas have been imaged at high angular resolution (1-3"; typically 200-600 AU) together with continuum emission at 230 GHz (1.3 mm) and 345 GHz (0.8 mm). Compact continuum emission is observed for all sources which likely originates in marginally optically thick circumstellar disks, with typical lower limits to their masses of 0.1 M_sun (1-10% of the masses of their envelopes) and having a dust opacity law with beta approximately 1. Prominent outflows are present in CO 2-1 observations in all sources: the most diffuse outflows are found in the sources with the lowest ratios of disk-to-envelope mass, and it is suggested that these sources are in a phase where accretion of matter from the envelope has almost finished and the remainder of the envelope material is being dispersed by the outflows. Other characteristic dynamical signatures are found with inverse P Cygni profiles indicative of infalling motions seen in the 13CO 2-1 lines toward NGC1333-IRAS4A and -IRAS4B. Outflow-induced shocks are present on all scales in the protostellar environments and are most clearly traced by the emission of CH3OH in NGC1333-IRAS4A and -IRAS4B. These observations suggest that the emission of CH3OH and H2CO from these proposed "hot corinos" are related to the shocks caused by the protostellar outflows. Only one source, NGC1333-IRAS2A, has evidence for hot, compact CH3OH emission coincident with the embedded protostar.
