description: This paper aims, through a critical analysis of the official Music Curriculum Document for Primary Education in Cyprus, to shed some light on concerns regarding its philosophy, expected outcomes, the methodology suggested, its content and finally student assessment. It seems that in spite of the changing times, traditional thinking continues to predominate in the music curriculum of Cyprus, a curriculum, which, was designed and developed based on a combination of the content and the objectives model. The critical analysis showed that it is a rather overloaded and over-academic document, which clearly gives great emphasis in the cognitive development of the students, neglecting the development of skills and positive attitudes towards classroom music. Besides, the study shows that apart, from various weaknesses to each part of the music curriculum document, there is no consistency and coherence between its various parts, most probably due to lack of philosophy both in music teaching as in curriculum design.

description: Mirror modes in collisionless high-temperature plasmas represent macroscopic high-temperature quasi-superconductors with bouncing electrons in discrete-particle resonance with thermal ion-sound noise contributing to the ion-mode growth beyond quasilinear stability. In the semi-classical GL approximation the conditions for phase transition are given. The quasi-superconducting state is of second kind causing a magnetically perforated plasma texture. Focussing on the interaction of mirror bubbles we apply semi-classical Josephson conditions and show that a mirror perforated plasma emits weak electromagnetic radiation which in the magnetosheath is in the sub-millimeter respectively infrared range.

Reaction-diffusion theory of localized structures with application to vertebrate organogenesis
Creators: name: Holloway, David M.
Publisher: name: University of British Columbia
Year: 2009

description: Biological pattern formation is addressed within the framework of Turing's (1952) chemical theory. His (linear) reaction-diffusion equations for chemical concentration have spatially inhomogeneous solutions. These stationary chemical waves are a possible mechanism for the spatial patterning of cellular differentiation in embryogenesis. Chemical mechanisms which give Turing dynamics have nonlinear rate equations. Much of the dynamics can be predicted from linear analysis, but solution is generally only possible numerically. Numerical methods for reaction-diffusion equations, especially implicit techniques, are reviewed. This work is specifically concerned with the localization of pattern. Reaction-diffusion models tend to form repeated peaks. Under some circumstances, however, patterns of localized peaks surrounded by large areas of low concentration can be formed. The requirements for this are developed and explored through comparison of two models, the Brusselator and the Gierer-Meinhardt. It is found that both can give localized pattern if the ratio of the component diffusivities is high. This leads to partly-ordered pattern, linking Turing theory with the inhibitory field theory of Wigglesworth (1940). However, the Gierer- Meinhardt gives less ordered pattern in two dimensions and is more susceptible to gradients in precursor concentration than the Brusselator. The different dynamics in the two models, underlying the different behaviours, are discussed. These principles of pattern localization in reaction-diffusion models are applied to heart formation in the axolotl, Ambystoma mexicanum. A form of the Gierer-Meinhardt model is used (but derived from a chemical mechanism), due to its greater tendency to form localized pattern. Heart formation proceeds by induction of the mesoderm tissue by the underlying endoderm, followed by more localized cardiomyocyte differentiation in the mesoderm. This sequence is modelled by treating induction as a process which establishes the distribution of a precursor in the reaction-diffusion mechanism postulated to be responsible for cardiomyocyte differentiation. Normal development, and numerous transplant and explant experiments with wild-type and cardiac-lethal mutant (c) tissues are successfully modelled. Agreement with experiment is achieved in terms of spatial patterns and timing of events. Predictions for future experiments are given, as well as some suggestions on the probable chemical nature of the morphogens, with some relationship to signal transduction mechanisms.

description: The aim of the study was to register, classify and analyze the phonological conception mistakes and differentiation in writing of pupils of 2nd, 3rd, 4th elementary school classes. Were examined written exercises of 480 pupils of 2nd, 3rd, 4th class, Based upon the analysis of the written exercises 72 pupils were chosen, which made specific writing mistakes. We proposed to each of these pupils three types of written exercises: dictation, copying and composition writing. We used a part of Lalaeva (1992) method "Classification of specific writing mistakes" for the classification and analysis of the phonological conception mistakes. The phonological conception and differentiation mistakes appear to all types of writing. The presence of those mistakes indicates incapacity in the phonological linguistic level. Those mistakes do not diminish from one class to another but maintain a constant and repetitive appearance and for this reason are characteristic in the writing of children with special learning disabilities

description: The activity of magnetars is powered by their intense and dynamic magnetic fields and has been proposed as the trigger to extragalactic Fast Radio Bursts. Here we estimate the frequency of crustal failures in young magnetars, by computing the magnetic stresses in detailed magneto-thermal simulations including Hall drift and Ohmic dissipation. The initial internal topology at birth is poorly known but is likely to be much more complex than a dipole. Thus, we explore a wide range of initial configurations, finding that the expected rate of crustal failures varies by orders of magnitude depending on the initial magnetic configuration. Our results show that this rate scales with the crustal magnetic energy, rather than with the often used surface value of the dipolar component related to the spin-down torque. The estimated frequency of crustal failures for a given dipolar component can vary by orders of magnitude for different initial conditions, depending on how much magnetic energy is distributed in the crustal non-dipolar components, likely dominant in newborn magnetars. The quantitative reliability of the expected event rate could be improved by a better treatment of the magnetic evolution in the core and the elastic/plastic crustal response, here not included. Regardless of that, our results are useful inputs in modelling the outburst rate of young Galactic magnetars, and their relation with the Fast Radio Bursts in our and other galaxies.

Energy Loss Versus Energy Gain of Heavy Quarks in a Hot Medium

description: We study the energy loss and the energy gain of heavy quarks in a hot thermal medium. These include the study of the energy change due to the polarization and to the interaction with the thermal fluctuations of the medium. The dynamics of the heavy quarks with the medium is described by the Wong equations, that allow for the inclusion of both the backreaction on the heavy quarks due to the polarization of the medium, and of the interaction with the thermal fluctuations of the gluon field. Both the momentum as well as the temperature dependence of the energy loss and gain of charm and bottom quark are studied. We find that heavy quark energy gain dominate the energy loss at high-temperature domain achievable at the early stage of the high energy collisions. This finding supports the recently observed heavy quarks results in Glasma and will have a significant impact on heavy quark observables at RHIC and LHC energies.

description: Two distinct phase transitions occur at different temperatures in QCD with adjoint fermions (aQCD): deconfinement and chiral symmetry restoration. In this model, quarks do no explicitely break the center Z(3) symmetry and therefore the Polyakov loop is a good order parameter for the deconfinement transition. We study monopole condensation by inspecting the expectation value of an operator which creates a monopole. Such a quantity is expected to be an order parameter for the deconfinement transition as in the case of fundamental fermions.

description: We have used the SHARP polarimeter at the Caltech Submillimeter Observatory to map the polarization at wavelengths of 350 and 450 micron in a ~2 x 3 arcmin region of the Orion Molecular Cloud. The map covers the brightest region of the OMC-1 ridge including the Kleinmann-Low (KL) nebula and the submillimeter source Orion-south. The ratio of 450-to-350 micron polarization is ~ 1.3 +/- 0.3 in the outer parts of the cloud and drops by a factor of 2 towards KL. The outer cloud ratio is consistent with measurements in other clouds at similar wavelengths and confirms previous measurements placing the minimum of the polarization ratio in dusty molecular clouds at a wavelength ~ 350 micron.

description: The present dissertation, entitled “Dinner in the Greco-Roman world and the common meals of the first Christian communities”, aims at examining the dinners of the first Christian communities which were founded by Apostle Paul under an archaeological, literary, sociological, historical and theological aspect. The Common meals are mainly referred in the New Testament and more precisely in the 1 Corinthians where Apostle Paul clearly mentions this primitive practice of the first Christian communities in 1st century AD. Aim of the present dissertation is to demonstrate the researchers’ aspects concerning the place where the first Christians where gathered in order to perform their common meals, the time of the gathering, the way the common dinners were taking place as well as the problems of social nature that surfaced during them among the members of the Corinthian Christian community. All the research was conducted with the assistance of written sources (New Testament, Old Testament, Religious texts, ancient Greek and Latin authors, etc.) and –of course- on the principles of Archaeology.

description: The origin and nature of ultra high energy cosmic rays remains being a mystery. However, great progress has been made in recent years due to the observations performed by the Pierre Auger Observatory and Telescope Array. In particular, it is believed that the composition information of the cosmic rays as a function of the energy can play a fundamental role for the understanding of their origin. The best indicators for primary mass composition are the muon content of extensive air shower and the atmospheric depth of the shower maximum. In this work we consider a maximum likelihood method to perform mass composition analyses based on the number of muons measured by underground muon detectors. The analyses are based on numerical simulations of the showers. The effects introduced by the detectors and the methods used to reconstruct the experimental data are also taken into account through a dedicated simulation that uses as input the information of the simulated showers. In order to illustrate the use of the method, we consider AMIGA (Auger Muons and Infill for the Ground Array), the low energy extension of the Pierre Auger Observatory that directly measures the muonic content of extensive air showers. We also study in detail the impact of the use of different high energy hadronic interaction models in the composition analyses performed. It is found that differences of a few percent between the predicted number of muons have a significant impact on composition determination.

description: We present a theory of the transmission of incoherent guided matter-waves through Sagnac interferometers. Interferometer configurations with only one input and one output port have a property similar to the phase rigidity observed in the transmission through Aharonov-Bohm interferometers in coherent mesoscopic electronics. This property is connected to the existence of counterpropagating paths of equal length and enables the operation of such matter-wave interferometers with incoherent sources. High finesse interferometers of this kind have a rotation sensitivity inversely proportional to the square root of the finesse.

description: The purpose of the present research was to investigate the effect of a caching based on a model that involves each form of art in the teaching of language, in the creative divergent expression of students. Fostering creativity through language goes beyond the limits of exercises in creative production. Furthermore, student’s holistic-ally expresses themselves when involved in understanding language through the Arts. The research was carried out with the students of two 4th grade classes. Teaching programs in two poems were applied and a test of divergent creative expression on these programs was used. The results show that a teaching model based on language and Art approach can positively influence some dimensions of creative expression -fluency and flexibility- but does not contribute to the development of originality in ideas.

The production of quark pairs from this background field is then computed nonperturbatively by numerically solving the Dirac equation in the classical background. The result seems to point towards an early chemical equilibration of the plasma.

description: Within a relativistic single particle model, we calculate the Coulomb sum rule of inclusive electron scattering from $^{40}$Ca and $^{208}$Pb in quasielastic region. Theoretical longitudinal and transverse structure functions are extracted for three momentum transfers from 300 to 500 MeV/c and compared with the experimental data measured at Bates and Saclay. We find that there is no drastic suppression of the longitudinal structure function and that the Coulomb sum rule depends on nucleus in our theoretical model.

description: High angular resolution observations of discs at mm wavelengths (on scales of a few au) are now commonplace, but there is a current lack of a comparable angular resolution for observations at cm wavelengths. This presents a significant barrier to improving our understanding of planet formation, in particular how dust grains grow from mm to cm sizes. In this paper, we examine the ability of the Square Kilometre Array (SKA) to observe dust substructure in a young, planet-forming disc at cm wavelengths. We use dusty hydrodynamics and continuum radiative transfer to predict the distribution and emission of 1 cm dust grains (or pebbles) within the disc, and simulate continuum observations with the current SKA1-MID design baseline at frequencies of 12.5 GHz (Band 5b, ~2.4 cm) on 5-10 au scales. The SKA will provide high-fidelity observations of the cm dust emission substructure in discs for integration times totalling 100's of hours. Radial structure can be obtained at a sufficient resolution and S/N from shorter (10's of hours) integration times by azimuthal averaging in the image plane. By modelling the intensity distribution directly in the visibility plane, it is possible to recover a similar level of (axisymmetric) structural detail from observations with integration times 1-2 orders of magnitude lower than required for high-fidelity imaging. Our results demonstrate that SKA1-MID will provide crucial constraints on the distribution and morphology of the raw material for building planets, the pebbles in protoplanetary discs.

Καταγράφεται επίσης ο νεο-παραληφθείς από το εξωτερικό στρατιωτικός εξοπλισμός και των 3 κλάδων των ελληνικών ενόπλων δυνάμεων, προκειμένου να διαπιστωθούν οι τρόποι και οι πηγές προμήθειάς του αλλά και η ενδεχόμενη επιχειρησιακή τους αναγκαιότητα, σε σχέση με τα γεγονότα του διεθνούς πολιτικού περιβάλλοντος.
description: The aim of the present thesis is to study if Greek governments behaved responsibly to the military armament procurement issue and to verify if their choices were strictly related to certain operational needs or they were influenced by non-operational reasons (mainly to achieve the selected targets of the Greek foreign affairs policy). More specifically, the historical background of the Greek military expenditures during 1950-1974 is being analyzed and also the main events of the international political environment, according to the admissible periodization (1950-1955, 1955-1967, 1967-1974) are presented. Additionally, the newly received foreign military equipment by the three branches of the Greek Armed Forces during the above-mentioned periods is being recorded, in order to verify the methods and sources of supply and their eventual operational need in relation with the events of the international political environment.

description: We study equilibrium as well as dynamical properties of the finite-size fully connected Ising model with a transverse field at the zero temperature. In relation to the equilibrium, we present approximate ground and first excited states that have large overlap -- except near the phase transition point -- with the exact energy eigenstates. For both the approximate and exact eigenstates, we compute the energy gap, concurrence, and geometric measure of quantum entanglement. We observe a good match in the case of energy gap and geometric entanglement between the approximate and exact eigenstates. Whereas, when the system size is large, the concurrence shows a nice agreement only in the paramagnetic phase. In a quench dynamics, we study the time period and the first critical time, which play important roles in the dynamical phase transitions, based on a dynamical order parameter and the Loschmidt rate, respectively. When all the spins are initially polarized in the direction of their mutual interaction, both the time period and critical time diverges logarithmically with the system size at the dynamical critical point. When all the spins are initially in the direction of transverse field, both the time period and critical time exhibit logarithmic or power-law divergences depending on the final field strength. In the case of convergence, we provide estimates for the finite-size scaling and converged value.

description: Context: The very young sigma Orionis cluster (about 3 Ma) is a cornerstone for the understanding of the formation of stars and substellar objects down to planetary masses. However, its stellar population is far to be completely known. Aims: This study has the purpose of identyfing and characterising the most massive stars of sigma Orionis to complement current and future deep searches for brown dwarfs and planetary-mass objects in the cluster. Methods: I have cross-correlated the sources in the Tycho and 2MASS catalogues in a region of 30 arcmin radius with centre in the O-type star sigma Ori A. In the area, I have studied the membership in the Ori OB 1b Association of the brightest stars in the optical using astrometric, X-ray and infrared and optical photometric data from public catalogues and spectroscopic data from the literature. Results: A list of 26 young stars, four candidate young stars and 16 probable foreground stars has arised from the study. Seven young stars probably harbour discs (four are new). There is no mass-dependence of the disc frequency in the cluster. I have derived for the first time the mass spectrum in sigma Orionis from 1.1 to 24 Msol (alpha = +2.0+0.2-0.1; roughly Salpeter-like). I have also provided additional proofs on the existence of several spatially superimposed stellar populations in the direction of sigma Orionis. Finally, the cluster may be closer and older than previously considered.

description: The study reports findings regarding 1) young children's responses to museum exhibits in the archaeological museum of Cyprus and 2) the impact of the museum visit on young children's art learning- The sample includes 32 children (16 boys and 16 girls) drawn randomly from two classrooms in two public nursery schools in Nicosia. An open-ended interview procedure was used to explore children's responses to museum exhibits. In addition methods include observational data form videotape recordings, teacher’s field notes and photographic material. Results suggest that: 1) children's' preferences seemed to be occurred by chance, 2) most of the children reacted positively to large in size museum exhibits or to exhibits that depicted favorite or familiar to them subject matter, 3) previous artistic experiences seemed to help children in recognizing the artistic medium and understanding the artistic process of the exhibits, 4) children were particularly interested in exploring the artistic medium than producing artistic products. The findings, corroborates the view of those who believe that children's contact with original exhibits in a museum setting is an important part of children's educational experiences and underlying the significance of a museum friendly environment, and appropriate educational programmes incorporating artistic activities in enhancing children's experiences and learning in museum settings.

description: An effective description for spherical nanoparticles in a fluid of point particles is presented. The points inside the nanoparticles and the point particles are assumed to interact via spherically symmetric additive pair potentials, while the distribution of points inside the nanoparticles is taken to be spherically symmetric and smooth. The resulting effective pair interactions between a nanoparticle and a point particle, as well as between two nanoparticles, are then given by spherically symmetric potentials. If overlap between particles is allowed, the effective potential generally has non-analytic points, but for each effective potential the expressions for different overlapping cases can be written in terms of one analytic auxiliary potential. Effective potentials for hollow nanoparticles (appropriate e.g. for buckyballs) are also considered, and shown to be related to those for solid nanoparticles. Finally, explicit expressions are given for the effective potentials derived from basic pair potentials of power law and exponential form, as well as from the commonly used London-Van der Waals, Morse, Buckingham, and Lennard-Jones potential. The applicability of the latter is demonstrated by comparison with an atomic description of nanoparticles with an internal face centered cubic structure.

description: Event-driven reactive functionalities are an urgent need in nowadays distributed service-oriented applications and (Semantic) Web-based environments. An important problem to be addressed is how to correctly and efficiently capture and process the event-based behavioral, reactive logic represented as ECA rules in combination with other conditional decision logic which is represented as derivation rules. In this paper we elaborate on a homogeneous integration approach which combines derivation rules, reaction rules (ECA rules) and other rule types such as integrity constraint into the general framework of logic programming. The developed ECA-LP language provides expressive features such as ID-based updates with support for external and self-updates of the intensional and extensional knowledge, transac-tions including integrity testing and an event algebra to define and process complex events and actions based on a novel interval-based Event Calculus variant.

description: Τhe objective 01 study was to investigate the developmental differences in aggression and attachment relations in adolescence with a sample of 205 junior and senior high school students. The results showed that boys report higher levels of physical and verbal aggression than girls and that, with increasing age, physical aggression reduces, with this reduction tending to be higher for girls than for boys. The investigation of the development characteristics of attachment relations showed that, in adolescence, boys report more secure attachment to mother than to father and friends. ln contrast, girls seem to maintain an equally secure attachment to to mother and friends. For girls, attachment to father was less secure.

Για την επίλυση αυτών μελετούμε τον αλγόριθμο της διαίρεσης για πολυώνυμα πολλών μεταβλητών και εισάγουμε την έννοια της βάσης Groebner. Η βάση Groebner έχει πολλά πλεονεκτήματα, καθώς με τη χρήση της απορρίπτονται ανεπιθύμητες ιδιότητες που προκύπτουν όταν χρησιμοποιούμε οποιαδήποτε άλλη βάση. Με τον αλγόριθμο Buchberger οδηγούμαστε στην κατασκευή μιας τέτοιας βάσης και έπειτα μελετούμε πώς απλοποιείται η βάση αυτή. Τέλος, γίνεται αναφορά στις εφαρμογές των ιδεωδών, των πολλαπλοτήτων και της βάσης Groebner στη θεωρία ελέγχου και συστημάτων.
description: In this study, we introduce the concept of affine varieties, which tend to be lines, surfaces and other objectives with higher dimension, as well as the concept of ideals, which are sets with special properties. Furthermore, we give solutions to the ideal memebership problem, to the ideal discription problem and to the implicit represantation problem. Some of those problems are resolved using Groebner basis, the division algorithm and its extention in multivariate polynomials. This basis is preferable, as it tends to exclude problems which arise when using any other bases. Moreover, there is a reference to Buchberger algorithm, used to construct such a basis. Finally, there is a survey on the applications of ideals, varieties and the Groebner basis in contol system theory.

description: In mixed linear models with nonnormal data, the Gaussian Fisher information matrix is called a quasi-information matrix (QUIM). The QUIM plays an important role in evaluating the asymptotic covariance matrix of the estimators of the model parameters, including the variance components. Traditionally, there are two ways to estimate the information matrix: the estimated information matrix and the observed one. Because the analytic form of the QUIM involves parameters other than the variance components, for example, the third and fourth moments of the random effects, the estimated QUIM is not available. On the other hand, because of the dependence and nonnormality of the data, the observed QUIM is inconsistent. We propose an estimator of the QUIM that consists partially of an observed form and partially of an estimated one. We show that this estimator is consistent and computationally very easy to operate. The method is used to derive large sample tests of statistical hypotheses that involve the variance components in a non-Gaussian mixed linear model. Finite sample performance of the test is studied by simulations and compared with the delete-group jackknife method that applies to a special case of non-Gaussian mixed linear models.

description: We study the flux tube junctions in the limit of large magnetic flux. In this limit the flux tube becomes a wall vortex which is a wall of negligible thickness (compared to the radius of the tube) compactified on a cylinder and stabilized by the flux inside. This wall surface can also assume different shapes that correspond to soliton junctions. We can have a flux tube that ends on a wall, a flux tube that ends on a monopole and more generic configurations containing all three of them. In this paper we find the differential equations that describe the shape of the wall vortex surface for these junctions. We will restrict to the cases of cylindrical symmetry. We also solve numerically these differential equations for various kinds of junctions. We finally find an interesting relation between soliton junctions and dynamical systems.
