description: Highly crystalline UO2 nanoparticles (NPs) with sizes of 2-3 nm were produced by fast chemical deposition of uranium(IV) under reducing conditions at pH 8-11. The particles were then characterized by microscopic and spectroscopic techniques including high-resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD), high-energy resolution fluorescence detection (HERFD) X-ray absorption spectroscopy at the U M4 edge and extended X-ray absorption fine structure (EXAFS) spectroscopy at the U L3 edge. The results of this investigation show that despite U(IV) being the dominant oxidation state of the freshly prepared UO2 NPs, they oxidize to U4O9 with time and under the X-ray beam, indicating the high reactivity of U(IV) under these conditions. Moreover, it was found that the oxidation process of NPs is accompanied by their growth in size to 6 nm. We highlight here the major differences and similarities of the UO2 NPs properties with PuO2, ThO2 and CeO2 NPs.

description: Το αντικείμενο της διπλωματικής εργασίας αφορά αρχικά τη βιβλιογραφική ανασκόπηση και μελέτη του ιστορικού υποβάθρου της καλλιτεχνικής δραστηριότητας της Liubov Popova. Το ενδιαφέρον επικεντρώνεται στα τελευταία χρόνια της ζωής της, τη διετία 1923- 1924 όπου φαίνεται να εφαρμόζει τις αποκτηθείσες γνώσεις και αντιλήψεις της επάνω σε αντικείμενα με περισσότερο χρηστική αξία παρά καλλιτεχνική. Αφορμή της συγκεκριμένης έρευνας στάθηκε το έργο της με τίτλο Κεντητό Εξώφυλλο, το οποίο δημιουργήθηκε στο χρονικό πλαίσιο 1923- 1924, εντάσσεται στο ρεύμα του Κονστρουκτιβισμού και της παραγωγικής τέχνης και ανήκει στη Συλλογή Κωστάκη του Κρατικού Μουσείου Σύγχρονης Τέχνης που εδράζει στη Θεσσαλονίκη. Εκτός από την βιβλιογραφική αυτή αναδίφυση και την προσπάθεια να απαντηθούν καίρια ερωτήματα αναφορικά με τη χρήση του εξωφύλλου και τον τρόπο δημιουργίας του, θα γίνει προσπάθεια τα ερωτήματα αυτά να τεκμηριωθούν και πρακτικά, με τη χρήση φυσικοχημικών τεχνικών. Τα αποτελέσματα των τεχνικών που επελέγησαν ώστε να συνδράμουν στη μελέτη του έργου τέχνης, θα οδηγήσουν στην ταυτοποίηση των υλικών κατασκευής του καθώς και στις χρωστικές που χρησιμοποιήθηκαν σε αυτά.
description: The purpose of this paper, primarily, is to review and study the historical background of Liubov Popova’s artistic life. The interest is focused on the years before she passes away, 1923- 1924, where she seems to implement her social, political and creative beliefs on projects that worth more as utilitarian objects than artistic ones. The basic motive for this paper was her project Embroidered Book Cover, created in the time frame 1923- 1924, is part of the Constructivist movement and belongs to the Costakis Collection of the State Museum of Contemporary Art, which is seated in Thessaloniki. Besides the bibliographical citation of historical data and the quest for finding some answers regarding the use of that book cover and the way it was made, effort will also be put onto the documentation of those questions with the use of physicochemical techniques. The results of the technics chosen, will lead to the identification of the construction materials of the embroidered book cover and the pigments that were used.

description: We study the 37 brightest radio sources in the Subaru/XMM-Newton Deep Field (SXDF). We have spectroscopic redshifts for 24 of 37 objects and photometric redshifts for the remainder, yielding a median redshift z_med for the whole sample of z_med ~= 1.1 and a median radio luminosity close to the `FRI/FRII' luminosity divide. Using mid-IR (Spitzer MIPS 24 um) data we expect to trace nuclear accretion activity, even if it is obscured at optical wavelengths, unless the obscuring column is extreme. Our results suggest that above the FRI/FRII radio luminosity break most of the radio sources are associated with objects that have excess mid-IR emission, only some of which are broad-line objects, although there is one clear low-accretion-rate object with an FRI radio structure. For extended steep-spectrum radio sources, the fraction of objects with mid-IR excess drops dramatically below the FRI/FRII luminosity break, although there exists at least one high-accretion-rate `radio-quiet' QSO. We have therefore shown that the strong link between radio luminosity (or radio structure) and accretion properties, well known at z ~ 0.1, persists to z ~ 1. Investigation of mid-IR and blue excesses shows that they are correlated as predicted by a model in which, when significant accretion exists, a torus of dust absorbs ~30% of the light, and the dust above and below the torus scatters >~1% of the light.

description: The theory developed in our previous papers is applied in this paper to investigate the dependence of slowing down of dynamics of glass-forming liquids on the attractive and repulsive parts of intermolecular interactions. Through an extensive comparison of the behavior of a Lennard-Jones glass-forming liquid and that of its WCA reduction to a model with truncated pair potential without attractive tail, we demonstrate why the two systems exhibit very different dynamics despite having nearly identical pair correlation functions. In particular, we show that local structures characterized by number of mobile and immobile particles around a central particle markedly differ in the two systems at densities and temperatures where their dynamics show large difference and nearly identical where dynamics nearly overlap. We also show how the parameter ψ(T ) that measures the role of fluctuations embedded in the system on size of the cooperatively reorganizing cluster (CRC) and the crossover temperature T a depend on the intermolecular interactions. These parameters stemming from the intermolecular interactions characterize the temperature and density dependence of structural relaxation time τ α. The quantitative and qualitative agreements found with simulation results for the two systems suggest that our theory brings out the underlying features that determine dynamics of glass-forming liquids.

We obtain a linear-time algorithm to count the sum of weights of subtrees of $T$. As applications, we characterize the tree with the diameter at least $d$, which has the maximum number of subtrees, and we characterize the tree with the maximum degree at least $Δ$, which has the minimum number of subtrees.

Minority opinion influence: the role of issue-involvement and similarity

Publisher: name: University of British Columbia

description: Social influence in marketing has generally been conceptualized in terms of conformity, where the individual's attitudes and behaviour are influenced by real or imagined group pressure. This is a one-way influence process where the group (majority) influences the individual. This research extends this conceptualization of social influence to include the influence of minority or deviant opinions. A simultaneous social influence paradigm is adopted, in which individuals may not only experience conformity pressure from the majority, but may also be subject to persuasion by minority opinions in the group. Such situations may arise in consumer groups as such organizational buying committees or families. Several conditions that may determine the extent of conformity or minority influence were delineated. It was hypothesized that the extent of social identification with a minority or majority source, i.e., source-similarity, would determine the extent of its influence. It was proposed that issue-involvement would play an important role in determining conformity versus minority influence effects, as well as interact significantly with source-similarity. The role of other mediating variables in this social influence process, such as source credibility and source feelings, were also explicated. An empirical test of the theory was undertaken through a 2 (high/low similarity) X 2 (high/low involvement) factorial design. Subject were exposed to persuasive communication from both a majority and a minority source, who advocated contrary positions. The two sources always assumed opposite social identities, and thus when one source was similar to the subject, the other was dissimilar. As anticipated, the minority opinion was more persuasive when the minority was similar, rather than dissimilar. However, this effect was dependent on the level of involvement. The results were generally consistent with the proposed model, with both similarity and involvement playing a crucial role in determining the extent of minority influence. Source credibility and feelings towards the source were both significant mediators in the social influence process. This research indicates a further need to explore the role of involvement in such simultaneous influence contexts using other consumer contexts, and it opens several avenues for future research.

description: Wastewater effluents directly discharged into nearby stream are eventually used to irrigate plants like sugarcane in Ghana. In this study, 24 triplicates sugarcane stems (sugarcane juice was extracted), 24 triplicates soil samples and 8 triplicates water samples were collected from sugarcane farms in four communities in Ashanti region of Ghana. Two of the communities were exposed to wastewater while the other two without wastewater contamination served as control. Metals (Pb, Cd, Cr, Cu, and Fe) concentration were determined in the digested samples using Spectra AA 220 flame atomic absorption spectrometer. The Pb concentration in all sugarcane juice samples ranged between 12.65 and 145.0 μg/L. The mean Cu concentration of the sugarcane juice samples varied between 11.28 and 156.00 μg/L. In general, there were decrease in metals investigated in sugarcane juice as you move away from the stream. However, the reduction was more pronounced in the hotspot sampling areas than control sampling areas. The EDI value was 9.76 × 10−4, 2.94 × 10−5, 1.09 × 10−3, and 9.07 × 10−3 (mg/kg-day) for Pb, Cd, Cu, and Fe, respectively. Mean hazard quotient (HQ) for the metals studied ranged from 0.036 (Fe) to 0.286 (Pb). The results of this study indicate that sugarcane is able to grow in soils where some metals are accumulated. High levels of metals were pronounced in sugarcane originating from wastewater polluted soils as those considered in this study. The consumption of normal quantity of sugarcane juice may not present detrimental health concerns through a lifetime based on the metals contents alone.

Dance-Means of Expression
Chronic Psychiatric Experience

description: Dance is being used by different human communities from ancient times as a way to enhance self – healing. Though, from the middle of 20th century dance was acknowledged as psycho-therapeutic tool and became part of the therapeutic procedures in clinical services in order to help to the psychosocial rehabilitation of people with psychotic experiences. The present research is an ethnographic study, which aims to examine the role of dance as a therapeutic tool in the development of verbal and non verbal expression of people with chronic psychiatric experiences. The method that has been used in the research is the participative observation. The researcher conducted a group with the name “Dance and Expression” in a day center of Thessaloniki in order to observe the functions of the dance in the process of the group. The results of the study have been analyzed with the principles of grounded theory. The thematic axes that have emerged were the difficulties in interactions between the members of the group, the idea of creativity as a mean to approach the participants of the the group, the procedures of the development of the communication and the sense of team spirit through the dance. To conclude with, the research underlines the contribution of the development of the non verbal expression during the dance group to the improvement of verbal expression of the members, to the improvement of interaction between them and to the improvement of the sense of team spirit.

description: The detection of gravitational radiation, emitted in the aftermath of the excitation of neutron star quasi-normal modes, has the potential to provide unprecedented access to the properties of matter in the star interior, and shed new light on the dynamics of nuclear interactions at microscopic level. Of great importance, in this context, will be the sensitivity to themodelling of three-nucleon interactions, which are known to play a critical role in the high-density regime. We report the results of a calculation of the frequencies and damping times of the fundamental mode, carried out using the equation of state of Akmal, Pandharipande and Ravenhall as a baseline, and varying the strength of the isoscalar repulsive term the Urbana IX potential within a range consistent with multimessenger astrophysical observations. The results of our analysis indicate that repulsive three-nucleon interactions strongly affect the stiffness of the equation of state, which in turn determines the pattern of the gravitational radiation frequencies, largely independent of the mass of the source. The observational implications are also discussed.

description: In order to face environmental constraints, trees are able to re-orient their axes by controlling the stress level in the newly formed wood layers. Angiosperms and gymnosperms evolved into two distinct mechanisms: the former produce a wood with large tension pre-stress on the upper side of the tilted axis, while the latter produce a wood with large compression pre-stress on the lower side. In both cases, the difference between this stress level and that of the opposite side, in light tension, generates the bending of the axis. However, light values of compression were sometimes measured in the opposite side of angiosperms. By analysing old data on chestnut and mani and new data on poplar, this study shows that these values were not measurement artefacts. This reveals that generating light compression stress in opposite wood contributes to improve the performance of the re-orientation mechanism.

description: This paper describes an operational evaluation of the US Environmental Protection Agency’s (EPA) Air Pollution Exposure Model (APEX). APEX simulations for a multipollutant ambient air mixture, i.e. ozone (O3), carbon monoxide (CO), and particulate matter 2.5 microns in diameter or less (PM2.5), were performed for two seasons in three study areas in central Los Angeles. APEX predicted microenvironmental concentrations were compared with concentrations of these three pollutants monitored in the Exposure Classification Project (ECP) study during the same periods. The ECP was designed expressly for evaluating exposure models and measured concentrations inside and outside 40 microenvironments. This evaluation study identifies important uncertainties in APEX inputs and model predictions useful for guiding further exposure model input data and algorithm development efforts. This paper also presents summaries of the concentrations in the different microenvironments.

description: The aim of the present thesis was the indexing of ABC books, written by Greek authors, that were published from 2000 to 2015, their categorization based on their form and genre and also the detection of their literary value. The term ABC book is being clarified, as well as, defined as genre of literature, while it is differentiated from the term primer. In the beginning, through the theoretic part, we dispose all theoretical approaches for reading and we attempt a historical retrospect for the primer. Throughout the analysis we adhere to a descriptive analysis model, based on set parameters concerning the structure and content of the ABC books. In the last part of the thesis basic conclusions are being presented.
Rhyming ability, phoneme identity, letter-sound knowledge, and the use of orthographic analogy by prereaders
Creators: name: Walton, Patrick D.
Publisher: name: University of British Columbia
Year: 2008

description: Recent research in phonological awareness found a strong link between rhyming ability in preschool children and later reading achievement. The use of orthographic analogy, the ability to make inferences from similarities in spelling to similarities in sound, was proposed as the mechanism to explain this relationship (Goswami & Bryant, 1990). Literature was presented that suggested the need for further research. Four research questions were examined. First, can prereaders learn to read unfamiliar words on the basis of orthographic analogy after brief training with rhyming words? The evidence supported the view that they could. Second, will the ability to read words by orthographic analogy be enhanced by phonological training in onset and rime, and by the use of segmented text? The brief phonological training did not increase analogy word reading over the same training without it. However, using text segmented at the onset-rime boundary for training items did increase analogy word reading. Third, will reading by orthographic analogy vary according to the level of prereading skills (rhyming ability, phoneme identity, letter-sound knowledge)? The majority of children with high prereading skills learned to read analogy test words whereas most children with low prereading skills found the task too arduous. Fourth, will rhyming ability make an independent contribution to reading achievement? The results were equivocal. Rhyming ability did make an independent contribution to the number of trials taken to learn the training items. It did not when analogy word reading was the dependent variable. Phoneme identity accounted for most of the variance in analogy word reading. Further analyses found that the ability to identify the final phoneme was the best discriminator between children who learned to read analogy test words and those who did not. A possible explanation was that children used the final phoneme to determine the sound of the rime ending rather than the last two phonemes together.

Given the urgent need to address this phenomenon, we suggest that desired public action toward these invasive vectors can be motivated through intentional framing in science communication. In this paper, we sought to evaluate the effect of framing about ZIKV (Zika virus) on reported willingness to comply with mosquito prevention action. Post framing intervention, we found a significant increase (N = 26, p

description: We exploit the properties of the three-dimensional hyperbolic space to discuss a simplicial setting for open/closed string duality based on (random) Regge triangulations decorated with null twistorial fields. We explicitly show that the twistorial N-points function, describing Dirichlet correlations over the moduli space of open N-bordered genus g surfaces, is naturally mapped into the Witten-Kontsevich intersection theory over the moduli space of N-pointed closed Riemann surfaces of the same genus. We also discuss various aspects of the geometrical setting which connects this model to PSL(2,C) Chern-Simons theory.

description: Studies on prospective memory (PM) predominantly assess either event- or time-based PM by implementing non-ecological laboratory-based tasks. The results deriving from these paradigms have provided findings that are discrepant with ecologically valid research paradigms that converge on the complexity and cognitive demands of everyday tasks. The Virtual Reality Everyday Assessment Lab (VR-EAL), an immersive virtual reality (VR) neuropsychological battery with enhanced ecological validity, was implemented to assess everyday event- and time-based PM, as well as the influence of other cognitive functions on everyday PM functioning. The results demonstrated the importance of delayed recognition, planning, and visuospatial attention on everyday PM. Delayed recognition and planning ability were found to be central in event- and time-based PM respectively. In order of importance, delayed recognition, visuospatial attention speed, and planning ability were found to be involved in event-based PM functioning. Comparably, planning, visuospatial attention accuracy, delayed recognition, and multitasking/task-shifting ability were found to be involved in time-based PM functioning. These findings further suggest the importance of ecological validity in the study of PM, which may be achieved using immersive VR paradigms.

description: It has recently been suggested that the power spectrum of redshifted 21cm fluctuations could be used to measure the scale of baryonic acoustic oscillations (BAOs) during the reionisation era. The resulting measurements are potentially as precise as those offered by the next generation of galaxy redshift surveys at lower redshift. However unlike galaxy redshift surveys, which in the linear regime are subject to a scale independent galaxy bias, the growth of ionised regions during reionisation is thought to introduce a strongly scale dependent relationship between the 21cm and mass power spectra. We use a semi-numerical model for reionisation to assess the impact of ionised regions on the precision and accuracy with which the BAO scale could be measured using redshifted 21cm observations. For a model in which reionisation is completed at z~6, we find that the constraints on the BAO scale are not systematically biased at z > 6.5. In this scenario, and assuming the sensitivity attainable with a low-frequency array comprising 10 times the collecting area of the Murchison Widefield Array, the BAO scale could be measured to within 1.5 per cent in the range 6.5 < z < 7.5.

description: We compute rigorously the ground and equilibrium states for Kitaev's model in 2D, both the finite and infinite version, using an analogy with the 1D Ising ferromagnet. Next, we investigate the structure of the reduced dynamics in the presence of thermal baths in the Markovian regime. Special attention is paid to the dynamics of the topological freedoms which have been proposed for storing quantum information.

description: Η παρούσα εργασία έχει ως κύριο θέμα τη μελέτη δειγμάτων από τοιχογραφίες της Κύπρου όπου χρονολογούνται από τον 6ο αιώνα μέχρι και τον 16ο αιώνα. Κύριος στόχος της εργασίας ήταν η ταυτοποίηση χρωστικών και οργανικών υλικών, καθώς και η μελέτη των κονιαμάτων για να προσδιορίσουμε διαφορές και ομοιότητες στον τρόπο παρασκευής των τοιχογραφιών όπου αλλάζει ανάλογα με την εποχή και τον εκάστοτε καλλιτέχνη. Η χρήση των τεχνικών που χρησιμοποιήθηκαν, αποσκοπούσε στη ταυτοποίηση των χρωστικών που περιλαμβάνονταν στη παλέτα του ζωγράφου της εποχής, την μελέτη των κονιαμάτων και των υλικών που εφαρμόστηκαν. Ο αριθμός των δειγμάτων λήφθηκε από διαφορετικές έγχρωμες περιοχές, γεγονός που μπορεί να βοηθήσει στην απόκτηση μιας ολοκληρωμένης γνώσης των χρωστικών που χρησιμοποιήθηκαν καθώς και των διαφορετικών χαρακτηριστικών και τεχνικών παρασκευής των τοιχογραφιών. Η πολυτεχνική αναλυτική προσέγγιση έχει αποδειχθεί ότι είναι ένα πολύ αποτελεσματικό εργαλείο για την ανάλυση έργων τέχνης. Επομένως όλες οι τεχνικές που χρησιμοποιήθηκαν για την ανάλυση των δειγμάτων, παρείχαν σημαντικά στοιχεία και πληροφορίες για την συντήρηση και την αποκατάσταση των τοιχογραφιών. Στις μικροσκοπικές τεχνικές χρησιμοποιήθηκαν, το στερεομικροσκόπιο, οπτικό μικροσκόπιο-μικροσκόπιο φθορισμού, το ηλεκτρονικό μικροσκόπιο σάρωσης SEM με διάταξη ενεργειακής διασποράς ακτίνων X EDS, στις φασματοσκοπικές τεχνικές χρησιμοποιήθηκε η φασματοσκοπία RΑMAN και η φασματοσκοπία υπέρυθρου FTIR.
description: This work has as main theme the study of frescoes of Cyprus which date from the 6th century to the 16th century. The main objective of the study was to identify pigments and organic materials, as the study of mortars to identify differences and similarities in the way of preparation of the frescoes which changes depend on the season and the individual artist. The techniques that they have been used in this study, intend to identify the pigments contained in the palette of the era painter, the study of mortars and pigments applied. Samples have been taken from different colored areas, which can help to obtain a comprehensive knowledge of pigments used and the different characteristics and technical preparation of the frescoes. The polytechnic analytical approach has proven to be a very effective tool for the analysis of works of art. Therefore all the techniques that have been used to analyze the samples will provide important data and information for the maintenance and restoration of the frescoes. The microscopic techniques that have been used are the stereo microscope, optical microscope - fluorescent microscope, scanning electron microscope (SEM) with energy dispersive X-ray Spectroscopy (EDS) and the spectroscopic techniques that we have used is RAMAN spectroscopy and infrared spectroscopy FTIR.

description: Highly entangled states called cluster states are a universal resource for measurement-based quantum computing (QC). Here we propose an efficient method for producing large cluster states using superconducting quantum circuits. We show that a large cluster state can be efficiently generated in just one step by turning on the inter-qubit coupling for a short time. Because the inter-qubit coupling is only switched on during the time interval for generating the cluster state, our approach is also convenient for preparing the initial state for each qubit and for implementing one-way QC via single-qubit measurements. Moreover, the cluster state is robust against parameter variations.

description: Phase-sensitive optical parametric amplification of squeezed states helps to overcome detection loss and noise and thus increase the robustness of sub-shot-noise sensing. Because such techniques, e.g., imaging and spectroscopy, operate with multimode light, multimode amplification is required. Here we find the optimal methods for multimode phase-sensitive amplification and verify them in an experiment where a pumped second-order nonlinear crystal is seeded with a Gaussian coherent beam. Phase-sensitive amplification is obtained by tightly focusing the seed into the crystal, rather than seeding with close-to-plane waves. This suggests that phase-sensitive amplification of sub-shot-noise images should be performed in the near field. Similar recipe can be formulated for the time and frequency, which makes this work relevant for quantum-enhanced spectroscopy.

description: Emergence of invasive vector species and the diseases they carry present a clear danger to the public as well as a challenge for scientists and experts to control effectively. Given the urgent need to address this phenomenon, we suggest that desired public action towards these invasive vectors can be motivated through intentional framing in science communication. In this paper, we sought to evaluate the effect of framing about ZIKV (Zika virus) on reported willingness to comply with mosquito prevention action. Post framing intervention, we found a significant increase (N=26, p<0.001) in individuals willing to take preventative action against mosquitoes. By methodically investigating best communication practices, this study and others can help practitioners mobilize communities to address large-scale ecological problems. Additionally, the principles outlined here may be transferrable to other communication efforts about ecological issues outside of ZIKV and mosquitoes.
