description: Η παρούσα Διπλωματική Εργασία, έχει ως σκοπό να διερευνήσει τη αποδοχή που θα είχε η υλοποίηση ενός μέσου Θαλάσσιας Αστικής Συγκοινωνίας στην ευρύτερη περιοχή της Θεσσαλονίκης.Συγκεκριμένα έγινε μια προσπάθεια προσδιορισμού του προτιμήσεων των κατοίκων και επισκεπτών στους δυο τερματικούς σταθμούς, δηλαδή στην περιοχή του Επιβατικού Λιμένα Θεσσαλονίκης και στην περιοχή της Περαίας.Μέσω της ανασκόπησης της διεθνούς και ελληνικής βιβλιογραφίας, επιχειρήθηκε η διερεύνηση θεμάτων που αφορούν στην λειτουργία και φύση ενός τέτοιου μέσου. Η έρευνα είχε ως στόχο την παρουσίαση του μέσου αυτού, καθώς και τον εντοπισμό παραγόντων, οι οποίοι θα μπορούσαν να επηρεάσουν την επιλογή των μετακινουμένωνΑκολούθησε η εκπόνηση έρευνας ερωτηματολογίου και η ανάλυση των στοιχείων που συλλέχτηκαν. Τέλος, διαμορφώθηκαν προτάσεις με βάση τα αποτελέσματα της ανάλυσης, ώστε να υποβοηθηθεί η διαδικασία ένταξης ενός τέτοιου μέσου στο δίκτυο αστικών συγκοινωνιών της πόλης.
description: The objective of the present Master Thesis is the investigation of the level of acceptance that a newly created urban maritime transport mode would have in the extended area of the city of Thessaloniki.More specifically an attempt was made to define the preferences of the residents and visitors in the areas of the two terminal stations, namely the Harbor of Thessaloniki and the residential area of Peraia.The literature review that was conducted for the purposes of this document, attempted to investigate topics that would illuminate the nature and operations of such a mode of transport. This research aimed to sufficiently present this mode and to identify factors that could influence the public’s choice of transport mode.Finally, a stated preference survey was conducted, followed by the analysis of the acquired date. Out of the results of this analysis the author outlined proposals, in order to facilitate the introduction of such a mode of transport in Thessaloniki.

description: Σκοπός της παρούσας εργασίας είναι να ερευνήσει τις απόψεις των μητέρων εφήβων και νέων με Σύνδρομο Down ηλικίας 15 μέχρι 35 ετών σε θέματα που αφορούν τις κοινωνικές σχέσεις και αλληλεπιδράσεις των παιδιών τους. Το δείγμα αποτελείται από σαράντα (40) μητέρες. Η επιλογή του συγκεκριμένου δείγματος έγινε, καθώς τα άτομα με ΣD αποτελούν την πιο αντιπροσωπευτική ομάδα ατόμων με νοητική ανεπάρκεια. Η έρευνα πραγματοποιήθηκε με τη χρήση δύο εργαλείων: 1. το 1ο από την κλίμακα “Arc’s Self Determination Scale” του Wehmeyer, που αφορά την «Αυτονομία» και 2. προσωπική συνέντευξη με ανοικτού τύπου ερωτήσεις. Από τα αποτελέσματα της έρευνας φαίνεται ότι οι μητέρες δεν είναι ευχαριστημένες από την ποιότητα των κοινωνικών σχέσεων των παιδιών τους με νοητική ανεπάρκεια και ότι η στάση της οικογένειας παίζει μεγάλο ρόλο στην ενίσχυση ή μη των σχέσεων. Επίσης, φαίνεται να υπάρχει συσχέτιση μεταξύ της αυτονομίας του ατόμου και των κοινωνικών του σχέσεων.
description: The aim of the specific study is to investigate the views of mothers of adolescents and of young with Down Syndrome, aged 15 to 35, in matters related to social relationships and interactions of their children. The sample consists of forty (40) mothers. The specific sample was chosen, as people with DS are the most representative group of individuals with mental retardation. The research was fulfilled with the use of two tools: 1. The 1st part of the “Arc’s Self Determination Scale” of Wehmeyer, on “Autonomy” and 2. Open-ended personal interviews. It becomes clear from the results that mothers of the mentally retarded children aren’t pleased with the quality of their social relationships and believe that family has a major role in the reinforcement of those. It also seems to exist a correlation between a person’s autonomy and its social relationships.

description: The starting point to understanding cluster properties is the putative global minimum and all the nearby local energy minima; however, locating them is computationally expensive and challenging due to a combinatorial explosion problem. The relative populations and spectroscopic properties of a molecule that are a function of temperature can be approximately computed by employing statistical thermodynamics. Here, we investigate temperature-entropy-driven isomers distribution on Be$_6$B$_{11}^{-}$ fluxional cluster and the effect of temperature on their infrared spectroscopy and relative populations. We identify the vibration modes possessed by the cluster that significantly contribute to the zero-point energy. A couple of steps are considered for computing the temperature-dependent relative population: First, using a genetic algorithm coupled to density functional theory, we performed an extensive and systematic exploration of the potential/free energy surface of Be$_6$B$_{11}^{-}$ cluster to locate the putative global minimum and elucidate the low-energy structures. Second, the relative populations' temperature effects are determined by considering the thermodynamic properties and Boltzmann factors. The temperature-dependent relative populations show that the entropies and temperature are essential for determining the global minimum. We compute the temperature-dependent total infrared spectra employing the Boltzmann factor weighted sums of each isomer's infrared spectrum and find that at finite temperature, the total infrared spectrum is composed of an admixture of infrared spectra that corresponds to the spectrum of the lowest energy structure and its isomers located at higher energies. The methodology and results describe the thermal effects in the relative population and the infrared spectra.
The Physical Properties of HD 3651B: An Extrasolar Nemesis?

description: I present detailed analysis of the near infrared spectrum of HD 3651B, a faint, co-moving wide companion to the nearby planet-hosting star HD 3651. These data confirm the companion as a brown dwarf with spectral type T8, consistent with the analysis of Luhman et al. Application of the semi-empirical technique of Burgasser, Burrows & Kirkpatrick indicates that HD 3651B has Teff = 790+/-30 K and log g = 5.0+/-0.3 for a metallicity of [M/H] = 0.12+/-0.04, consistent with a mass M = 0.033+/-0.013 M_sun and an age of 0.7-4.7 Gyr. The surface gravity, mass and age estimates of this source are all highly sensitive to the assumed metallicity; however, a supersolar metallicity is deduced by direct comparison of spectral models to the observed absolute fluxes. The age of HD 3651B is somewhat better constrained than that of the primary, with estimates for the latter ranging over ~2 Gyr to >12 Gyr. As a widely orbiting massive object to a known planetary system that could potentially harbor terrestrial planets in its habitable zone, HD 3651B may play the role of Nemesis in this system.

description: Universal quantum computers are the only general purpose quantum computers known that can be implemented as of today. These computers consist of a classical memory component which controls the quantum memory. In this paper, the space complexity of some data stream problems, such as PartialMOD and Equality, is investigated on universal quantum computers. The quantum algorithms for these problems are believed to outperform their classical counterparts. Universal quantum computers, however, need classical bits for controlling quantum gates in addition to qubits. Our analysis shows that the number of classical bits used in quantum algorithms is equal to or even larger than that of classical bits used in corresponding classical algorithms. These results suggest that there is no advantage of implementing certain data stream problems on universal quantum computers instead of classical computers when space complexity is considered.

description: Strong and weak (1, 3) homotopies are equivalence relations on knot projections, defined by the first flat Reidemeister move and each of two different types of the third flat Reidemeister moves. In this paper, we introduce the cross chord number that is the minimal number of double points of chords of a chord diagram. Cross chord numbers induce a strong (1, 3) invariant. We show that Hanaki's trivializing number is a weak (1, 3) invariant. We give a complete classification of knot projections having trivializing number two up to the first flat Reidemeister moves using cross chord numbers and the positive resolutions of double points. Two knot projections with trivializing number two are both weak (1, 3) homotopy equivalent and strong (1, 3) homotopy equivalent if and only if they can be related by only the first flat Reidemeister moves. Finally, we determine the strong (1, 3) homotopy equivalence class containing the trivial knot projection and other classes of knot projections.

description: The spacetime metric around a rotating SuperConductive Ring (SCR) is deduced from the gravitomagnetic London moment in rotating superconductors. It is shown that theoretically it is possible to generate Closed Timelike Curves (CTC) with rotating SCRs. The possibility to use these CTC's to travel in time as initially idealized by Gödel is investigated. It is shown however, that from a technology and experimental point of view these ideas are impossible to implement in the present context.

description: Spectra of pions, which are known as the pseudo-Goldstone bosons of spontaneous chiral symmetry breaking, as well as their relationship with chiral phase transition and pion superfluidity phase transition, have been investigated in the framework of soft-wall AdS/QCD. In chiral limit, it is proved both numerically and analytically that pions are massless Goldstone bosons even at finite temperature, which was usually considered as an assumption in soft-wall models. Above $T_c$, at which chiral condensate $\langle \bar{q}q\rangle$ vanishes, the spectra of pions and scalar mesons merge together, showing the evidence of the restored chiral symmetry in hadronic spectrum level. Extending to finite quark mass, pion masses increase with quark mass. Further, it is more interesting to observe that the pole masses of pions decrease with temperature below $T_c$, which agrees with the analysis in Phys.Rev.Lett.88(2002)202302. Meanwhile, symmetry restoration above $T_c$ could be seen in the spectra of scalar and pseudo-scalar mesons. With finite temperature and isospin chemical potential $μ_I$, it is shown that the masses of charged pions would split. The mass of positive charged pion $π^+$ decreases almost linearly to zero when $μ_I$ grows to $μ_{I}^c$, where pion condensation starts to form. This reveals the Goldstone nature of $π^+$ after pion superfluidity transition, which are closely related to the experimental observation.

description: A possible candidate for the late time accelerated expanding Universe is phantom energy, which possesses rather bizarre properties, such as the prediction of a Big Rip singularity and the violation of the null energy condition. The latter is a fundamental ingredient of traversable wormholes, and it has been shown that phantom energy may indeed sustain these exotic geometries. Inspired by the evolving dark energy parameter crossing the phantom divide, we consider in this work a varying equation of state parameter dependent on the radial coordinate, i.e., $ω(r)=p(r)/ρ(r)$. We shall impose that phantom energy is concentrated in the neighborhood of the throat, to ensure the flaring out condition, and several models are analyzed. We shall also consider the possibility that these phantom wormholes be sustained by their own quantum fluctuations. The energy density of the graviton one loop contribution to a classical energy in a phantom wormhole background and the finite one loop energy density are considered as a self-consistent source for these wormhole geometries. The latter semi-classical approach prohibits solutions with a constant equation of state parameter, which further motivates the imposition of a radial dependent parameter, $ω(r)$, and only permits solutions with a steep positive slope proportional to the radial derivative of the equation of state parameter, evaluated at the throat. The size of the wormhole throat as a function of the relevant parameters is also explored.

description: Some recent studies have examined the gamma-ray flux profile of our Galaxy to determine the signal of dark matter annihilation. However, the results are controversial and no confirmation is obtained. In this article, we study the radio flux density profile of the M31 galaxy and show that it could manifest a possible signal of dark matter annihilation. By comparing the likelihoods between the archival observed radio flux density profile data and the predicted radio flux density profile contributed by dark matter and stellar emission, we can constrain the relevant dark matter parameters. Specifically, for the thermal annihilation cross section via the $b\bar{b}$ channel, the best-fit value of dark matter mass is $\sim 30$ GeV, which is consistent with the results of many recent studies. We expect that this method would become another useful way to constrain dark matter, which is complementary to the traditional radio analyses and the other indirect detections.

Η παρούσα διπλωματική εργασία έχει ακριβώς αυτό το σκοπό, την αξιολόγηση του σχολικού βιβλίου της ιστορίας της έκτης τάξης δημοτικού σχολείου που εκδόθηκε τον Σεπτέμβρη του 2012. Η αξιολόγηση αυτή βασίζεται στην ανάλυση των συμπερασμάτων που προέκυψαν από συνεντεύξεις με διδάσκοντες του συγκεκριμένου μαθήματος. Μέσα από μια ποιοτική προσέγγιση διερευνώνται τα τεχνικά και τυπο-εκδοτικά χαρακτηριστικά του εγχειριδίου, η δομή και η οργάνωσή του, το περιεχόμενο, η εικονογράφηση, η γλώσσα και η αναγνωσιμότητα καθώς και η μεθοδολογία, ενώ διατυπώνονται γενικά σχόλια και προτείνονται ενδεικνυόμενες βελτιώσεις στα υπό μελέτη πεδία. Η αποδελτίωση των συμπερασμάτων αποτυπώνει την αρνητική κριτική των διδασκόντων για το εγχειρίδιο, κυρίως ως προς τα χαρακτηριστικά του περιεχόμενου. Κυρίαρχη είναι η θέση πως δεν στηρίζει αποτελεσματικά το μαθητή στην καθημερινή του εργασία. Το ύφος της γλώσσας δεν θεωρείται φιλικό προς το χρήστη και πολλές φορές φαίνεται να μπερδεύει το μαθητή. Λίγοι τομείς του εγχειριδίου κρίθηκαν θετικά, κυρίως τα τυπο-εκδοτικά χαρακτηριστικά που θεωρείται ότι είναι καλής ποιότητας και η συμβατότητά του με το αναλυτικό πρόγραμμα. Στο θέμα των απαραίτητων βελτιώσεων κυριάρχησε η άποψη ότι το βιβλίο χρειάζεται επανασυγγραφή.
description: Textbooks play an important role in the efficiency of the education system as a benchmark of everyday teaching practice for teachers, students, as well as field evaluation, analysis of special education researchers. This thesis is exactly this purpose, evaluation of textbook history of sixth grade elementary school adopted in September 2012. The evaluation is based on analysis of the findings from interviews with teachers of this course. Through a qualitative approach explored the technical and publishing-type features manual, structure and organization, content, illustration, language and readability as well as the methodology and makes general comments and propose appropriate improvements in the study fields. The indexing of findings reflects the criticism of teachers for the user, particularly as to the characteristics of the content. A dominant position is not that effectively support the student in his daily work. The style of the language is not considered user friendly and often seem to confuse the student. Few areas of the manual were considered positive, mainly publishing-type features that are considered to be of good quality and compatibility with the curriculum. On the issue of the necessary improvements dominated the view that the book needs rewriting.

description: With the Treaty of Lausanne in 1923, the Muslims of Thrace were exempted from the population exchange between Greece and Turkey, remained in the area and formed the Muslim minority of Western Thrace, the only officially recognized minority of the Greek state. The purpose of this particular study is to highlight the multiculturalism of the Muslim minority of Western Thrace, the attitude of the Greek State against people of minority and more specifically, the state policies followed 'before' and 'after' Greece's accession to the European Union, to understand, first, the degree of implementation of minority rights from a European country such as Greece and then the degree and extent of the impact of these policies. Finally, this study aims to identify, collect and record the basic requirements of the Muslim minority of Western Thrace, opposite the Greek state, as reflected by the corresponding literature (Greek and foreign), but also by their own representatives of the minority.
Routes to chaos, universality and glass formation

description: We review recent results obtained for the dynamics of incipient chaos. These results suggest a common picture underlying the three universal routes to chaos displayed by the prototypical logistic and circle maps. Namely, the period doubling, intermittency, and quasiperiodicity routes. In these situations the dynamical behavior is exactly describable through infinite families of Tsallis' $q$-exponential functions. Furthermore, the addition of a noise perturbation to the dynamics at the onset of chaos of the logistic map allows to establish parallels with the behavior of supercooled liquids close to glass formation. Specifically, the occurrence of two-step relaxation, aging with its characteristic scaling property, and subdiffusion and arrest is corroborated for such a system.

Invisible and pervasive imagery in three art classrooms

Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to discover and explore issues relating to the inclusion and exclusion of 'pervasive' and / or 'invisible' imagery in three secondary art teachers' visual arts programs. The term 'pervasive' refers to visual forms that are prevalent in popular culture. The term 'invisible' refers to visual forms that are not commonly addressed in visual arts programs. Many of the images in both categories attend to such themes as violence, racism, sexism, death, war, and disease — subjects which individuals may consider disturbing, controversial or sensitive. This descriptive, qualitative study employed a case study design. The researcher conducted audio-taped interviews with participating teachers and collected field notes in relation to inclass activities where appropriate. Further data were collected through casual conversations with teachers, follow-up interviews, photographs of student art work, and sample instructional materials. This study has indicated that the teachers' general use or non-use of pervasive and invisible imagery is shaped by their values and purposes, and is influenced by their own and their students' responses to specific imagery, their relationships with school administrators, other staff members and students, their individual employment situations, and the approaches they utilize in regards to such imagery. As a result of the findings, avenues for further research were suggested, and implications for the development and implementation of art instructional resources and working curriculum models that directly address and provide successful teaching strategies relating to the classroom use of pervasive and invisible imagery were made.

description: Trigonometric parallaxes of 16 nearby planetary nebulae are presented, including reduced errors for seven objects with previous initial results and results for six new objects. The median error in the parallax is 0.42 mas, and twelve nebulae have parallax errors less than 20 percent. The parallax for PHL932 is found here to be smaller than was measured by Hipparcos, and this peculiar object is discussed. Comparisons are made with other distance estimates. The distances determined from these parallaxes tend to be intermediate between some short distance estimates and other long estimates; they are somewhat smaller than estimated from spectra of the central stars. Proper motions and tangential velocities are presented. No astrometric perturbations from unresolved close companions are detected.

description: Warm Neptune GJ3470b has been recently observed in 23S-23P transition of metastable helium, yielding absorption of about 1% in Doppler velocity range of [-40; 10] km/s. Along with previous detection of absorption in Lyα with depth of 20-40% in the blue and red wings of the line, it offers a complex target for simulation and testing of the current models. Obtained results suggest that absorption in both these lines comes from interaction of expanding upper planetary atmosphere with stellar plasma wind, allowing to constrain the stellar plasma parameters and the helium abundance in planet atmosphere.

description: This poster illustrates how I have incorporated three different computer scripts into e-resource workflows to manage the large sets of metadata used to provide access and discovery of the library’s electronic resources and increase the volume of the work. The poster will illustrate the three different workflows and provide screenshots of the computer code and the scripts in action. The first script I will present is the E-Resource Access Checker developed by Kristinia Sprugin which I have edited to meet my library’s needs and use to ensure our patrons are presented with functioning URLs to access an e-resource, cutting down on dead or incorrect links in our discovery system. The second script is one I developed in collaboration with collection development librarians to assist with making decisions about e-resources. The script enables a librarian to input a list of titles being considered for cancelation, and the script then uses the WorldCat Knowledge Base (WCKB) API to find the different means of access and their associated coverage dates, thus making is easier to get the information needed for their decisions. The last script automates batch searches of WorldCat using the WorldCat Search API. I use the script to harvest metadata to enrich publisher-provided metadata in the WCKB and to create new collections in the WCKB to provide access to e-resources which we couldn’t previously. The poster will help facilitate discussions about these kinds of innovative practices and facilitate collaboration on related projects.

description: Σκοπός της παρούσας μεταπτυχιακής εργασίας ήταν η μελέτη του τρόπου διαχείρισης διαπροσωπικών σχέσεων που αναπτύσσονται μεταξύ των παιδιών σε επικινδυνότητα για μαθησιακές δυσκολίες και παιδιών τυπικής ανάπτυξης από τους νηπιαγωγούς. Αρχικά αναλύθηκαν διαφόρων ειδών διαπροσωπικές σχέσεις, φιλικές σχέσεις, συγκρούσεις, συνεργασία, ανταγωνισμός, εκφοβισμός και θυματοποίηση. Η μελέτη αφορούσε αυτές τις σχέσεις που χρήζουν διαχείρισης από την πλευρά των εκπαιδευτικών (συγκρούσεις, ανταγωνισμός, εκφοβισμό και θυματοποίηση), έτσι μελετήθηκαν τόσο ο βαθμός εκδήλωσης αυτών των συμπεριφορών από παιδιά προσχολικής ηλικίας σε επικινδυνότητα για μαθησιακές δυσκολίες και παιδιά προσχολικής ηλικίας τυπικής ανάπτυξης όσο και ο τρόπος διαχείρισης αυτών των συμπεριφορών από τους νηπιαγωγούς συγκριτικά στις δύο ομάδες παιδιών.
description: The aim of the present thesis, was the study, of how to manage interpersonal relationships which were developed between preschool children at risk for learning disabilities and non retarded preschool children. At the beginning, interpersonal relationships were analyzed, such as friendships, conflicts, co-operations , competition, bulling and victimization. Furthermore, the interpersonal relationships, which may need teacher’s intervention (conflicts, competition, bulling and victimization) were also examined. Namely, the rate that preschool children at risk for learning disabilities and non retarded preschool children, was examined at that kind of relationships. Lastly, the way that kindergarteners management interpersonal relationships at these two children groups was examined too.

description: Due to the growing role of the SEO technologies, it is necessary to perform an automated analysis of the article's quality. Such approach helps both to return the most intelligible pages for the user's query and to raise the web sites positions to the top of query results. An automated assessment of a coherence is a part of the complex analysis of the text. In this article, main methods for text coherence measurements for Ukrainian language are analyzed. Expediency of using the semantic similarity graph method in comparison with other methods are explained. It is suggested the improvement of that method by the pre-training of the neural network for vector representations of sentences. Experimental examination of the original method and its modifications is made. Training and examination procedures are made on the corpus of Ukrainian texts, which were previously retrieved from abstracts and full texts of Ukrainian scientific articles. The testing procedure is implemented by performing of two typical tasks for the text coherence assessment: document discrimination task and insertion task. Accordingly to the analysis it is defined the most effective combination of method's modification and its parameter for the measurement of the text coherence.

Passive decoy state quantum key distribution: Closing the gap to perfect sources
Creators: name: Mauerer, Wolfgang

Publisher: name: arXiv
Year: 2006
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We propose a quantum key distribution scheme which closely matches the performance of a perfect single photon source. It nearly attains the physical upper bound in terms of key generation rate and maximally achievable distance. Our scheme relies on a practical setup based on a parametric downconversion source and present-day, non-ideal photon-number detection. Arbitrary experimental imperfections which lead to bit errors are included. We select decoy states by classical post-processing. This allows to improve the effective signal statistics and achievable distance.

A VLBI Search for Radio Supernovae in Wolf Rayet Galaxies

description: We have used the VLBI High Sensitivity Array (VLBA with VLA, Green Bank Telescope, and Arecibo) to search for young radio supernovae in three nearby Wolf Rayet dwarf galaxies containing Super Star Clusters (SSCs) and signs of extreme star formation in the last few million years. No milliarcsecond radio sources were detected in II Zw 40, He 2-10, or NGC 5253, implying that these galaxies contain few radio supernovae, despite the fact that they have at least some star formation going back to 10 million years ago. The upper limits of the source powers range from 6 x 10^17 W/Hz to ~2 x 10^18 W/Hz at 5 GHz, roughly 0.6 to 2.2 times the power of the galactic supernova remnant Cassiopeia A. Comparison with the radio supernova population in Arp 299 implies that the current supernova rates in the three dwarf galaxies are below 10^{-2}/yr, consistent with standard star formation models that predict supernova rates of 10^{-3}/yr or less in our targets. In He 2-10, the VLBI non-detection of a compact VLA source with a significant nonthermal component indicates that this source may be dominated by one or more supernova remnants with ages of a few hundred years or more, which are comparable to Cas~A in power, and size.

description: We show that a Rubidium vapor can be produced within the core of a photonic band-gap fiber yielding an optical depth in excess of 2000. Our technique for producing the vapor is based on coating the inner walls of the fiber core with an organosilane and using light-induced atomic desorption to release Rb atoms into the core. We develop a model to describe the dynamics of the atomic density, and as an initial demonstration of the potential of this system for supporting ultra-low-level nonlinear optical interactions, we perform electromagnetically-induced transparency with control-field powers in the nanowatt regime, which represents more than a 1000-fold reduction from the power required for bulk, focused geometries.
Weakly nonlinear topological gap solitons in Su-Schrieffer-Heeger photonic lattices

description: We study both theoretically and experimentally the effect of nonlinearity on topologically protected linear interface modes in a photonic Su-Schrieffer-Heeger (SSH) lattice. It is shown that under either focusing or defocusing nonlinearity, this linear topological mode of the SSH lattice turns into a family of topological gap solitons. These solitons are stable. However, they exhibit only a low amplitude and power and are thus weakly nonlinear, even when the bandgap of the SSH lattice is wide. As a consequence, if the initial beam has modest or high power, it will either delocalize, or evolve into a soliton not belonging to the family of topological gap solitons. These theoretical predictions are observed in our experiments with optically induced SSH-type photorefractive lattices.

The star formation efficiency and its relation to variations in the initial mass function

description: We investigate how the dynamical state of a turbulently supported, 1000 solar mass, molecular cloud affects the properties of the cluster it forms, focusing our discussion on the star formation efficiency (SFE) and the initial mass function (IMF). A variety of initial energy states are examined in this paper, ranging from clouds with PE = 0.1 KE to clouds with PE = 10 KE, and for both isothermal and piece-wise polytropic equations of state (similar to that suggested by Larson). It is found that arbitrary star formation efficiencies are possible, with strongly unbound clouds yielding very low star formation efficiencies. We suggest that the low star formation efficiency in the Maddelena cloud may be a consequence of the relatively unbound state of its internal structure. It is also found that competitive accretion results in the observed IMF when the clouds have initial energy states of PE >= KE. We show that under such conditions the shape of the IMF is independent of time in the calculations. This demonstrates that the global accretion process can be terminated at any stage in the cluster's evolution, while still yielding a distribution of stellar masses that is consistent with the observed IMF. As the clouds become progressively more unbound, competitive accretion is less important and the protostellar mass function flattens. These results predict that molecular clouds should be permeated with a distributed population of stars that follow a flatter than Salpeter IMF.

description: Feeds provide nutrients to animals. Feeds can be grains, crop by-products or forages. Forages can form the basis of feeds for goats in the southeastern US because year-round forage production is possible. Since goats are classified as browsers, the forage program should consist of browse and pasture. Managing browse species as feed resources is challenging, and there is limited information relative to managing browse species. Hay is the main forage feed for goats in the region and average quality hay can meet nutrient requirements for maintenance. However, nutrient requirements for late-pregnancy, lactation, and growing goats cannot be met with the average quality hay alone. There is a need for supplemental feeds when hay quality and quantity are inadequate. This situation arises during winter months and in late summer. Many supplemental feeds can be fed to goats such as grains, crop byproducts, commercial feed supplements or concentrates including salts and minerals.
Dance in education : a focus on aesthetic development
Creators: name: Neale, Aileen Mary
Publisher: name: University of British Columbia
Year: 2009

description: This study focuses on aesthetic development, its nurture and assessment, in dance education. Observations, interviews, and examinations of student journals, were used to collect data for this multiple case study. Four classroom settings provided a picture of aesthetic growth representing a range of ages. The findings were examined in light of the symbolic theory of the arts developed by Suzanne Langer (1953), aesthetic learning through entry to the world of play described by Huizinga (1950), and the developmental aesthetic model of Malcolm Ross (1984). Significant descriptions voiced by the participants provide snapshots of student growth at various stages of development. The study concludes that the aesthetic experience, defined as the simultaneous engagement of intellect and emotions, is indeed evident in dance to both the dancer and the observer; it may be seen and recognized as a special quality which invariably draws the eye and focuses the viewer's attention. Opportunities for such engagement are carefully structured by effective teachers. While stages of aesthetic growth are evident, students of al l ages grow aesthetically in individual ways; aesthetic understanding results from complex combinations of social, psychological, and experiential factors, as well as maturation.
Cosmology in the Solar System: Pioneer effect is not cosmological

description: Does the Solar System and, more generally, a gravitationally bound system follow the cosmic expansion law ? Is there a cosmological influence on the dynamics or optics in such systems ? The general relativity theory provides an unique and unambiguous answer, as a solution of Einstein equations with a local source in addition to the cosmic fluid, and obeying the correct (cosmological) limiting conditions. This solution has no analytic expression. A Taylor development of its metric allows a complete treatment of dynamics and optics in gravitationally bound systems, up to the size of galaxy clusters, taking into account both local and cosmological effects. In the solar System, this provides an estimation of the (non zero) cosmological influence on the Pioneer probe: it fails to account for the " Pioneer effect " by about 10 orders of magnitude. We criticize contradictory claims on this topic.
