description: Στην παρούσα εργασία μελετήθηκε ο αποπολυμερισμός του πολυ(τερεφθαλικού αιθυλενεστέρα) (ΡΕΤ) που παραλήφθηκε από χρησιμοποιημένες φιάλες συσκευασίας νερού. Η αντίδραση που πραγματοποιήθηκε ήταν η αλκαλική υδρόλυση του ΡΕΤ υπό ακτινοβόληση με μικροκύματα, ενώ σε ορισμένες περιπτώσεις χρησιμοποιήθηκε και καταλύτης μεταφοράς φάσης. Ο σκοπός της εργασίας ήταν να διαπιστωθεί κατά πόσο μπορεί η χρήση των μικροκυμάτων να συντομεύσει τον χρόνο της αντίδρασης και/ή να αυξήσει την απόδοσή της. Οι παράμετροι της αντίδρασης που μελετήθηκαν ήταν η επίδραση της θερμοκρασίας τόσο παρουσία καταλύτη (από 70-90 οC) όσο και χωρίς καταλύτη (από 120-180 οC), η συγκέντρωση του αλκαλικού διαλύματος (από 2,5-10,0 % w/v), η συγκέντρωση του καταλύτη (από 0.005-0,030 mol TOMAB/mol PET),το είδος του καταλύτη (βρωμιούχο τριοκτυλομεθυλαμμώνιο, βρωμιούχο δεκαεξυλοτριμεθυλαμμώνιο) και η συγκέντρωση του ΡΕΤ (από 0,4-0,7 g ΡΕΤ). Το τερεφθαλικό οξύ που παραλήφθηκε μετά το τέλος της αντίδρασης ταυτοποιήθηκε τόσο ογκομετρικά όσο και με φασματοσκοπία FΤ-IR. Τα αποτελέσματα έδειξαν ότι η χρήση των μικροκυμάτων συντομεύει κατά πολύ τον απαιτούμενο χρόνο για την ολοκλήρωση της αντίδρασης. Επίσης, η χρήση του καταλύτη επιτρέπει την πραγματοποίηση της αντίδρασης σε χαμηλότερες θερμοκρασίες, διατηρώντας τα ίδια επίπεδα απόδοσης.
description: Recycling of PET using hydrolytic depolymerization in an alkaline solution, under microwave irradiation is examined. The main product of this reaction is terephtalic acid, which was analyzed and identified. The effects of reaction temperature, time and alkaline concentration were investigated. Microwave irradiation was found to shorten very much the time needed to achieve a specific TPA yield.

Influence of client social class on therapists’ perceptions and evaluations
Creators: name: Hutchings, Anita Clare
Publisher: name: University of British Columbia
Year: 2009

description: This study was designed to explore whether initial information on client social class would impact negatively on the therapist's perception, evaluation and proposed treatment of the client. Respondents were randomly selected (N= 300) from the membership lists of the British Columbia Psychological Association and the Canadian Guidance and Counselling Association (British Columbian members). The return rate was 37% (N= 111). Of these, 49 were returned from the British Columbia Psychological Association and 62 from the Canadian Guidance and Counselling Association. Each respondent read the client information forms. They then filled out a questionnaire containing a seven-point Likert scale, a qualitative response section, a semantic differential of opposing adjectives, a respondent relationships form, and a demographics section. Half of the questionnaires contained the description of a lower social class client, and half contained the description of a middle class client. All remaining information was identical. Examination by total sample population, association and gender all produced significant results linked to client social class. The lower class client was evaluated as less intelligent, less knowledgeable, less capable, less clean, less hostile, louder, and more emotional than the middle class client. The CGCA respondents produced lower frequencies of presenting problems for the lower class client. Doctoral degree respondents produced less significant bias than respondents with master's degrees. An unusual pattern of evaluation linked to respondents' years of experience was apparent, however results by client social class were not significant. Caution is advised when translating results to real-life situations since counsellors may not necessarily respond in the same way in a real counselling setting as they would to a hypothetical client.

description: Using the logarithmic superfluid model of physical vacuum, one can formulate a quantum theory, which successfully recovers Einstein's theory of relativity in low-momenta limit, but otherwise has different foundations and predictions. We present an analytical example of the dispersion relation and argue that it should have a Landau "roton" form which ensures the suppression of dissipative fluctuations. We show that at small momenta, a dispersion relation becomes relativistic with small deformations, such that a photon acquires effective mass, but a much more complex picture arises at large momenta.

description: Scanning $μ$SQUID force microscopy is used to study magnetic flux structures in single crystals of the layered spin triplet superconductor Sr$\_{2}$RuO$\_{4}$. Images of the magnetic flux configuration above the $\vec{a}\vec{b}$-face of the cleaved crystal are acquired, mostly after field-cooling the sample. For low applied magnetic fields, individual vortices are observed, each carrying a single quantum of flux. Above 1 gauss, coalescence of vortices is discovered. The coalescing vortices may indicate the presence of domains of a chiral order parameter. When the applied field is tilted from the $\vec{c}$-axis, we observe a gradual transition from vortex domains to vortex chains. The in-plane component of the applied magnetic field transforms the vortex domains to vortex chains by aligning them along the field direction.This behavior and the inter-chain distance varies in qualitative agreement with the Ginzburg Landau theory of anisotropic 3D superconductors. The effective mass anisotropy of Sr$\_{2}$RuO$\_{4}$, $γ$=20, is the highest observed in three dimensional superconductors. When the applied field is closely in plane, the vortex form flux channels confined between the crystal-layers. Residual Abrikosov vortices are pinned preferentially on these channels. Thus the in-plane vortices are decorated by crossing Abrikosov vortices: two vortex orientations are apparent simultaneously, one along the layers and the other perpendicular to the layers.

The lived experience and meaningful construction of traumatic brain injury from the perspectives of the survivor, the family and the treatment professional
Creators: name: Connell, J. Ellen
Publisher: name: University of British Columbia
Year: 2009

description: This study presents a revelatory case study which draws on phenomenological constructs to explore the lived experience of perceiving and meaningfully constructing traumatic brain injury from the perspectives of a survivor, a family member, and a treatment professional working with the survivor. During in-depth, individual interviews, the participants shared their experiences and described the processes through which they came to understand and make sense of the survivor's traumatic brain injury (TBI), the impact it had on the survivor, as well as their relationships with the survivor. The interviews were then transcribed and analysed using Collaizi's (1978) method of phenomenological analysis. A number of themes emerged which appeared to be central to the processes of understanding and making sense of this TBI for these individuals. These included: the sense of recovery from TBI as a process; the role of awareness in coping with, and adjusting to TBI; the importance of spirituality and optimism in the recovery process; the importance of collaborative goal setting and client-centred rehabilitation. The survivor who participated in this study assessed his recovery as very good, and his family member, and the rehabilitation professional interviewed for this study reinforced this opinion. Furthermore, the survivor described a sense of having "found himself through his rehabilitation and recovery experience, and described a sense of satisfaction and meaning in his life which he attributed to his recovery experience. There was a consensus among the individuals who participated in this study regarding appropriate and meaningful goals and priorities. These findings indicate that in this case a client centred approach to rehabilitation was extremely effective.

description: Using a single-plaquette approximation, novel magnetoinductance effects in Josephson junction arrays (JJAs) are predicted, including the appearance of steps in the temperature behavior of magnetic susceptibility. The number of steps (as well as their size) is controlled by the kinetic inductance of the plaquette whose field dependence is governed by the Abrikosov vortices penetrating superconducting regions of the array. The experimental conditions under which the predicted effects should manifest themselves in artificially prepared JJAs are discussed.

description: In an effort to reduce gas emissions from fuel combustion generated by the transportation sector the use of lightweight materials such as composites are currently being intensively explored. Fuel-economy improvement for passenger vehicles is projected to increase by 6-7 % for every 10 % of weight reduction. Composite materials are stronger than steel and lighter than aluminium. Fibre Metal Laminates (FML) is a class of composite material comprised by alternating aluminium sheets and composites which has been successfully employed in the aerospace industry. The resulting synergy of material properties gives FMLs superior mechanical properties when compared with those of their individual constituent materials. FMLs based on thermoplastic composites have been shown to possess better fracture toughness, shorter processing times, good impact and localised blast resistance as well as being recyclable. For the automotive industry to take advantage of FML's superior mechanical properties, the forming behaviours of this class of material need to be understood. Stamp forming is a much cheaper way to produce FML parts in high-volume industries compared to autoclaving. FML systems can be immediately used as a replacement for metal in production lines with minimal change to stamp-forming tools. Two systems of FML with different fiber stiffness, FMIL-Curv and FML-Twintex, were benchmarked with monolithic aluminium of the same thickness to study their formability. Full factorial experimental work was conducted to study the influence of process parameters -binder force, feedrate and preheat temperature, using the Swift test. The Swift round-bottom test was chosen to study both stretch and draw behaviour during forming. A full field-strain measurement system was used to study the effects of varying forming conditions on strain evolution in real time during the stamp-forming process. A statistical test, ANOVA, shows that preheat temperature and binder force have significant effects on strain evolution for both FML systems. FML samples showed better strain distribution in stretch forming compared to monolithic aluminium. They also required less work to form and have a weight reduction of approximately 30% when compared to aluminium samples. High-temperature forming is preferred for FML-Twintex while low-temperature forming is better for FML-Curv. FML-Curv can also be formed to higher depths compared to monolithic aluminium. By proper selection of process parameters, contact conditions and composite fiber properties it is possible to produce FML parts that have superior formability characteristics compared to monolithic metals. A predictive finite element model was developed to model forming process. The results from the finite element solution showed a high degree of correlation with experimental results.

description: Shock compression of air is observed in numerous situations ranging from explosions to hypersonic vehicle entry into atmosphere. In an effort to develop continuum-based equation of state for air subjected to shock compression, it is necessary to understand the dynamics of the shock compression process with regards to formation of new chemical species in air at the molecular level. With this in perspective, three different models of air (consisting a mixture of O2, N2 and CO2 gas, with or without H2O based on presence of humidity) are subjected to shock compression ranging from 0.5 km s−1 to 5.0 km s−1 particle velocities. Thermodynamic quantities are evaluated to plot Rankine Hugoniot planes for the three different air models: dry air at mean sea level (MSL), humid air at MSL and dry air at high altitude level of 36 000 ft above MSL. It is observed that high shock velocities eventually results in dissociation of gaseous molecules and formation of new gaseous species which has been quantified in the manuscript.

description: We study in detail the properties of pi-fluxes embedded in a state with a finite density of anyons that form either a Fermi liquid or a Bose-Einstein condensate. By employing a recently developed exact lattice bosonization in 2D, we demonstrate that such pi-flux remains a fully deconfined quasiparticle with a finite energy cost in a Fermi liquid of emergent fermions coupled to a Z2 gauge field. This pi-flux is accompanied by a screening cloud of fermions, which in the case of a Fermi gas with a parabolic dispersion binds exactly 1/8 of a fermionic hole. In addition there is a long-ranged power-law oscillatory disturbance of the liquid surrounding the pi-flux akin to Friedel oscillations. These results carry over directly to the pi-flux excitations in orthogonal metals. In sharp contrast, when the pi-flux is surrounded by a Bose-Einstein condensate of particles coupled to a Z2 gauge field, it binds a superfluid half-vortex, becoming a marginally confined excitation with a logarithmic energy cost divergence.

description: Gaussian Processes (GPs) has experienced tremendous success in geoscience in general and for bio-geophysical parameter retrieval in the last years. GPs constitute a solid Bayesian framework to formulate many function approximation problems consistently. This paper reviews the main theoretical GP developments in the field. We review new algorithms that respect the signal and noise characteristics, that provide feature rankings automatically, and that allow applicability of associated uncertainty intervals to transport GP models in space and time. All these developments are illustrated in the field of geoscience and remote sensing at a local and global scales through a set of illustrative examples.

description: Pseudo-telepathy is the most recent form of rejection of locality. Many of its properties have already been discovered: for instance, the minimal entanglement, as well as the minimal cardinality of the output sets, have been characterized. This paper contains two main results. First, we prove that no bipartite pseudo-telepathy game exists, in which one of the partners receives only two questions; as a corollary, we show that the minimal "input cardinality", that is, the minimal number of questions required in a bipartite pseudo-telepathy game, is 3x3. Second, we study the Bell-type inequality derived from the pseudo-telepathy game known as the Magic Square game: we demonstrate that it is a tight inequality for 3 inputs and 4 outputs on each side and discuss its weak resistance to noise.

Social and Economic Sustainability Targets in Construction
Creators: name: Gibberd, Jeremy
Publisher: name: Zenodo
Year: 2022

description: Sustainable development is based on approaches that reduce negative environmental impacts while creating beneficial social and economic impacts. While there has been extensive research on the negative environmental impacts of construction, less work has been done on the social and economic benefits that can be generated. In countries with high levels of unemployment and inequality, like South Africa, it is important to understand how beneficial impacts can be created to respond to local challenges. This chapter reviews the economic and social benefits that can be created through construction. It outlines how targets can be set and achieved through structured processes that include increased awareness, capacity development, proactive planning, target setting, procurement and support. Approaches are illustrated through examples and discussed.  The chapter will be of interest to government officials, developers, contractors, researchers and built environment professionals wishing to understand how beneficial social and economic impacts can be created through construction.

description: Στην παρούσα εργασία μελετώνται τα συνοπτικά και δυναμικά χαρακτηριστικά της δομής της ανώτερης τροπόσφαιρας κατά την διάρκεια ενός έντονου επεισοδίου μεταφοράς στρατοσφαιρικού αέρα έως την επιφάνεια του εδάφους στην Αθήνα στις 9 Οκτωβρίου 2003. Η μελέτη των πεδίων του γεωδυναμικού ύψους σε διάφορες ισοβαρικές στάθμες δείχνει την παρουσία ενός ισχυρού αυλώνα πάνω από τον Ελλαδικό χώρο. Η εξέταση των κατακόρυφων τομών των πεδίων της ειδικής και σχετικής υγρασίας επιβεβαιώνουν την μεταφορά ξηρού στρατοσφαιρικού αέρα μέχρι την επιφάνεια του εδάφους. Η ανάλυση των πεδίων του δυνητικού στροβιλισμού σε διάφορες ισοβαρικές και ισεντροπικές επιφάνειες καθώς και κατακόρυφες τομές απεικονίζει την αναδίπλωση της τρατόπαυσης και την δυναμική εξέλιξη του φαινομένου. Τέλος χρησιμοποιώντας το Λαγκραντζιανό μοντέλο διασποράς σωματιδίων Flexpart, εντοπίζονται οι πηγές και η πορεία των στρατοσφαιρικών σωματιδίων, ενώ παράλληλα πραγματοποιείται ποσοτική μελέτη του επεισοδίου μεταφοράς όζοντος από την στρατόσφαιρα στην επιφάνεια του εδάφους.
description: The present study investigates the synoptic and dynamic features of the upper troposphere during an intense stratospheric intrusion event down to the earth's surface in the Athens area on 9 October 2003. The study of the geopotential height fields at various isobaric levels indicates an intense trough extending over Greece. The inspection of relative and specific humidity vertical cross-sections, confirms the transport of dry, with stratospheric origin, air down to the ground surface. Furthermore the analysis of potential vorticity fields at several isobaric and isentropic levels as well as at vertical cross-sections illustrates clearly the tropopause fold and the dynamical evolution of the event. Finally, the Langrangian particle dispersion model FLEXPART was used, in order to calculate the trajectories of air particles and the fraction of particles with stratospheric origin.

description: Shock compression of air is observed in numerous situations ranging from explosions to hypersonic vehicle entry into atmosphere. In an effort to develop continuum-based equation of state for air subjected to shock compression, it is necessary to understand the dynamics of the shock compression process with regards to formation of new chemical species in air at the molecular level. With this in perspective, three different models of air (consisting a mixture of O2, N2 and CO2 gas, with or without H2O based on presence of humidity) are subjected to shock compression ranging for 0.5 km s−1 to 5.0 km s−1 particle velocities. Thermodynamic quantities are evaluated to plot Rankine Hugoniot planes for the three different air models: dry air at mean sea level (MSL), Humid air at MSL and dry air at high altitude level of 36 000 ft above MSL. It is observed that high shock velocities eventually results in dissociation of gaseous molecules and formation of new gaseous species which has been quantified in the manuscript.
CAFE-GAN: Arbitrary Face Attribute Editing with Complementary Attention Feature

description: The goal of face attribute editing is altering a facial image according to given target attributes such as hair color, mustache, gender, etc. It belongs to the image-to-image domain transfer problem with a set of attributes considered as a distinctive domain. There have been some works in multi-domain transfer problem focusing on facial attribute editing employing Generative Adversarial Network (GAN). These methods have reported some successes but they also result in unintended changes in facial regions - meaning the generator alters regions unrelated to the specified attributes. To address this unintended altering problem, we propose a novel GAN model which is designed to edit only the parts of a face pertinent to the target attributes by the concept of Complementary Attention Feature (CAFE). CAFE identifies the facial regions to be transformed by considering both target attributes as well as complementary attributes, which we define as those attributes absent in the input facial image. In addition, we introduce a complementary feature matching to help in training the generator for utilizing the spatial information of attributes. Effectiveness of the proposed method is demonstrated by analysis and comparison study with state-of-the-art methods.

description: We investigate an effective Hamiltonian for QCD at large s, in which longitudinal gauge degrees of freedom are suppressed, but not eliminated. In an axial gauge the effective field theory is a set of coupled (1+1)-dimensional principal-chiral models, which are completely integrable. The confinement problem is solvable in this context, and we find the longitudinal and transverse string tensions with techniques already used for a similar Hamiltonian in (2+1)-dimensions. We find some a posteriori justification for the effective Hamiltonian as an eikonal approximation. Hadrons in this approximation consist of partons, which are quarks and soliton-like excitations of the sigma models. Diffractive hadron-hadron scattering appears primarily due to exchange of longitudinal flux between partons.

description: We illustrate the general scheme of the Sum Rule (SR) method using 2D Quantum Harmonic Oscillator (2DQHO) as a toy model. We introduce correlator, related to Green function of 2DQHO, and describe the property of Asymptotic Freedom for 2DQHO. We explain how the duality conception allows one to describe excited states. Finally we present numerical results and extract some lessons to learn from our exposition. Then we switch to the QCD and show that QCD SRs supply us the method to study hadrons in non-perturbative QCD. Here the main emphasis is put on the pion and its distribution amplitude and form factors.

description: We present the ROGER (Reconstructing Orbits of Galaxies in Extreme Regions) code, which uses three different machine learning techniques to classify galaxies in, and around, clusters, according to their projected phase-space position. We use a sample of 34 massive, $M_{200}>10^{15} h^{-1} M_{\odot}$, galaxy clusters in the MultiDark Planck 2 (MDLP2) simulation at redshift zero. We select all galaxies with stellar mass $M_{\star} \ge 10^{8.5} h^{-1}M_{\odot}$, as computed by the semi-analytic model of galaxy formation SAG, that are located in, and in the vicinity of, the clusters and classify them according to their orbits. We train ROGER to retrieve the original classification of the galaxies out of their projected phase-space positions. For each galaxy, ROGER gives as output the probability of being a cluster galaxy, a galaxy that has recently fallen into a cluster, a backsplash galaxy, an infalling galaxy, or an interloper. We discuss the performance of the machine learning methods and potential uses of our code. Among the different methods explored, we find the K-Nearest Neighbours algorithm achieves the best performance.

description: We review the equation of state of QCD matter at finite densities. We discuss the construction of the equation of state with net baryon number, electric charge, and strangeness using the results of lattice QCD simulations and hadron resonance gas models. Its application to the hydrodynamic analyses of relativistic nuclear collisions suggests that the interplay of multiple conserved charges is important in the quantitative understanding of the dense nuclear matter created at lower beam energies. Several different models of the QCD equation of state are discussed for comparison.

description: In this paper we study the interaction of a Dirac-Pauli particle with an electromagnetic plane wave, by using a previously given generalization of the pseudo-classical Lagrangian for a spinning particle with an anomalous magnetic moment. We derive the explicit expressions for the eigenfunctions and the Green's functions of the theory. We discuss the validity of the semi-classical approach by comparing the wavefunctions with the (pseudo)-classical solutions of the Hamilton-Jacobi equation.

The language of child’s play: thematic representations of healing through the process of play therapy

Publisher: name: University of British Columbia
Year: 2009

description: Play therapy has been used for treating maladjusted children for decades and although it is recognized as a treatment of choice, a scarcity of verified, systematic knowledge on the process children typically move through within therapy exists in the literature. This qualitative single case study documents the process of play therapy over twenty sessions with an eight year old child who experienced maternal loss and separation, parental neglect, parental drug abuse and chronic instability in her home environment. A detailed account of the child's perceptions of her experience as well as the progression of the therapeutic relationship as it emerges and transforms over time is described. Significant issues of concern, areas of struggle, and patterns of improvement are documented through the evolution of the play therapy process, House-Tree-Person drawings and parent reports on the Child Behavior Checklist. The therapeutic process evolved across five phases, each illustrating specific behavioural and thematic developments and changes. This phasic process is consistent with the general findings of several play therapy clinicians and researchers. Although each of the five phases is not corroborated entirely by a single existing theory, several of the characteristic themes, play behaviours and transitions within each phase are documented in previous research. The findings of this study highlight the importance of the therapeutic relationship in the psychological healing process. The effects of parental neglect and separation are also discussed in terms of these findings. The results of this study enhance the understanding of the therapeutic process of play therapy, demonstrate the psychological effects of parental neglect and separation and indicate the importance of a consistent and nurturing parent to a child's development.

description: In today's globalized field of business, products and services are moving across the world. The requirements that concern the quality of these increase by the day. The main consumers request is the satisfaction of their demand reliably and expediently. The sound and immediate coverage of demand requires proper planning by the business. Planning refers to the procurement, production, storage and finally the transport and distribution of goods. This case study analyses the administration system of two products in a commercial enterprise. The presentation of the systems used until now is followed by the calculation of the total managing cost of stocks of goods and later by the study of products and the design of a model for forecasting the demand of them. Moving downwards new administration systems of stocks are being proposed based on parameterization which relied on this undertaking and took into account the nature of the materials and the environment. Finally, the use of the total cost as the comparison axis between the two existing systems and proposed two, gives the solution to the problem of the management design of selected species in the field of storage and ordering.
A finite volume method for two-moment cosmic-ray hydrodynamics on a moving mesh

description: We present a new numerical algorithm to solve the recently derived equations of two-moment cosmic ray hydrodynamics (CRHD). The algorithm is implemented as a module in the moving mesh Arepo code. Therein, the anisotropic transport of cosmic rays (CRs) along magnetic field lines is discretised using a path-conservative finite volume method on the unstructured time-dependent Voronoi mesh of Arepo. The interaction of CRs and gyroresonant Alfvén waves is described by short-timescale source terms in the CRHD equations. We employ a custom-made semi-implicit adaptive time stepping source term integrator to accurately integrate this interaction on the small light-crossing time of the anisotropic transport step. Both the transport and the source term integration step are separated from the evolution of the magneto-hydrodynamical equations using an operator split approach. The new algorithm is tested with a variety of test problems, including shock tubes, a perpendicular magnetised discontinuity, the hydrodynamic response to a CR overpressure, CR acceleration of a warm cloud, and a CR blast wave, which demonstrate that the coupling between CR and magneto-hydrodynamics is robust and accurate. We demonstrate the numerical convergence of the presented scheme using new linear and non-linear analytic solutions.
