description: Most ions lack the fast, cycling transitions that are necessary for direct laser cooling. In most cases, they can still be cooled sympathetically through their Coulomb interaction with a second, coolable ion species confined in the same potential. If the charge-to-mass ratios of the two ion types are too mismatched, the cooling of certain motional degrees of freedom becomes difficult. This limits both the achievable fidelity of quantum gates and the spectroscopic accuracy. Here we introduce a novel algorithmic cooling protocol for transferring phonons from poorly- to efficiently-cooled modes. We demonstrate it experimentally by simultaneously bringing two motional modes of a Be$^{+}$-Ar$^{13+}$ mixed Coulomb crystal close to their zero-point energies, despite the weak coupling between the ions. We reach the lowest temperature reported for a highly charged ion, with a residual temperature of only $T\lesssim200~\mathrm{μK}$ in each of the two modes, corresponding to a residual mean motional phonon number of $\langle n \rangle \lesssim 0.4$. Combined with the lowest observed electric field noise in a radiofrequency ion trap, these values enable an optical clock based on a highly charged ion with fractional systematic uncertainty below the $10^{-18}$ level. Our scheme is also applicable to (anti-)protons, molecular ions, macroscopic charged particles, and other highly charged ion species, enabling reliable preparation of their motional quantum ground states in traps.

description: We characterize highly coherent transmon qubits fabricated with a direct-write photolithography system. Multi-layer evaporation and oxidation allows us to change the critical current density by reducing the effective tunneling area and increasing the barrier thickness. Surface treatments before resist application and again before evaporation result in high coherence devices. With optimized surface treatments we achieve energy relaxation $T_1$ times in excess of $80\ μ$s for three dimensional transmon qubits with Josephson junction lithographic areas of 2 $μ\mathrm{m}^2$.

description: The Fisher-Shannon information and a statistical measure of complexity are calculated in the position and momentum spaces for the wave functions of the quantum isotropic harmonic oscillator. We show that these magnitudes are independent of the strength of the harmonic potential. Moreover, for each level of energy, it is found that these two indicators take their minimum values on the orbitals that correspond to the classical (circular) orbits in the Bohr-like quantum image, just those with the highest orbital angular momentum.

description: We used the Joint Lightcurve Analysis of SNIa in order to constrain the matter density parameter Ωm within a flat ΛCDM model. We conducted the analysis for the whole sample, for the two galactic hemispheres and for spatially coherent groups in different solid angles. 1) We reproduced results for the cosmological analysis of previous literature work with SNIa probes. 2) We found statistically important distinct distributions for the Ωm derived from the Hubble expansion of groups of SNIa among the two galactic hemispheres within a flat ΛCDM model. This is true considering either spatially coherent groups or groups of random SNIa as to galactic longitude and suggests an anisotropy of the Hubble expansion between the two hemispheres within this model

description: Australia’s changing social demographic and subsequent flow-on effects to volunteer recruitment presents a challenge to palliative care volunteering. Whilst the ACT’s volunteer enrolement leads the country, it can also expect to be subject to the impact of an aging population who themselves may require increasingly higher levels of support near the end of life. How might a response be fashioned to these broad social changes that will preserve the place of the volunteer in palliative care and enable the role to transform to a changing social world? The data collected aim at answering the following questions: - Identify how current volunteers envision the profile and context of their role in eight years time, - Identify those elements of their current role that should be maintained, and - Consider innovations to the role that respond to social changes. Data based on 4 focus groups with a total of 28 participants (semi structured questions.). 4 transcripts with 28 data sources, recorded on a digital recorder and then converted into text. Ethics reviewed by the Calvary Health Care (Australian Capital Territory) and ACU Ethics committees.

description: With a primary goal of conducting precision weak lensing measurements from space, the COSMOS survey has imaged the largest contiguous area observed by the Hubble Space Telescope (HST) to date using the Advanced Camera for Surveys (ACS). This is the first paper in a series where we describe our strategy for addressing the various technical challenges in the production of weak lensing measurements from the COSMOS data. The COSMOS ACS catalog is constructed from 575 ACS/WFC tiles (1.64 deg^2) and contains a total 1.2x10^6 objects to a limiting magnitude of F814W=26.5. This catalog is made publicly available. The shapes of galaxies have been measured and corrected for the distortion induced by the time varying ACS Point Spread Function and for Charge Transfer Efficiency effects. Next, simulated images are used to derive the shear susceptibility factors that are necessary in order to transform shape measurements into unbiased shear estimators. Finally, for each galaxy, we derive a shape measurement error and utilize this quantity to extract the intrinsic shape noise of the galaxy sample. Interestingly, our results indicate that the intrinsic shape noise varies little with either size, magnitude or redshift. Representing a number density of 66 galaxies per arcmin^2, the final COSMOS weak lensing catalog contains 3.9x10^5 galaxies with accurate shape measurements. The properties of the COSMOS weak lensing catalog described throughout this paper will provide key input numbers for the preparation and design of next-generation wide field space missions.

description: Methamphetamine use is a growing public health concern associated with severe mental health challenges such as anxiety, depression, and psychosis. This study examined the influence of family dynamics on methamphetamine usage and mental health among in-patients and out-patients in mental health facilities in Port Harcourt, Nigeria. A cross-sectional survey design was employed, and data were collected from 83 respondents using structured questionnaires, including the Drug Abuse Screening Test (DAST-10), Index of Family Relations (IFR) Scale, and Self-Reporting Questionnaire (SRQ-20). Findings revealed that 79.5% of the respondents were male, and 78.3% came from polygamous family backgrounds. A significant proportion (90.4%) exhibited high or severe methamphetamine use, while 88.0% displayed symptoms of mental health distress. Pearson correlation analysis showed a statistically significant relationship between family dynamics and methamphetamine use (r = 0.512, p < 0.01) as well as between family dynamics and mental health distress (r = 0.530, p < 0.01). The study highlights that dysfunctional family structures, poor parental supervision, and adverse childhood experiences contribute to increased substance abuse and mental health challenges. Based on these findings, the study recommends family-centered interventions, including improved communication, conflict resolution, and emotional support programs. Healthcare providers should integrate family assessments into substance abuse and mental health treatment plans. Additionally, policymakers should allocate resources for family therapy and substance abuse prevention programs. Further research is required to explore causal relationships, cultural differences, and the effectiveness of family-based interventions in mitigating substance abuse and improving mental health outcomes

description: The interaction between water and ions within droplets plays a key role in the chemical reactivity of atmospheric and man-made aerosols. Here we report direct computational evidence that in supercooled aqueous nanodroplets a lower density core of tetrahedrally coordinated water expels the cosmotropic ions to the denser and more disordered subsurface. In contrast, at room temperature, depending on the nature of the ion the radial distribution in the droplet core is nearly uniform or elevated towards the center. We analyze the spatial distribution of a single ion in terms of a reference electrostatic model. The energy of the system in the analytical model is expressed as the sum of the electrostatic and surface energy of a deformable droplet. The model predicts that the ion is subject to a harmonic potential centered at the droplet's center of mass. We name this effect "electrostatic confinement". The model's predictions are consistent with the simulation findings for a single ion at room temperature but not at supercooling. We anticipate this study to be the starting point for investigating the structure of supercooled (electro)sprayed droplets that are used to preserve the conformations of macromolecules originating from the bulk solution.

T-Matrix Approach to Quarkonium Correlation Functions in the QGP

Year: 2006
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We study the evolution of heavy quarkonium states with temperature in a Quark Gluon Plasma (QGP) by evaluating the in-medium Q-\bar{Q} T-matrix within a reduced Bethe-Salpeter equation in both S- and P-wave channels. The underlying interaction kernel is extracted from recent finite-temperature QCD lattice calculations of the singlet free energy of a Q-\bar{Q} pair. The bound states are found to gradually move above the Q-\bar{Q} threshold after which they rapidly dissolve in the hot system. The T-matrix approach is particularly suited to investigate these mechanisms as it provides a unified treatment of bound and scattering states including threshold effects and the transition to the (perturbative) continuum. We apply the T-matrix to calculate Q-\bar{Q} spectral functions as well as pertinent Euclidean-time correlation functions which are compared to results from lattice QCD. A detailed analysis reveals large sensitivities to the interplay of bound and scattering states, to temperature dependent threshold energies and to the "reconstructed" correlator used for normalization. We furthermore investigate the impact of finite-width effects on the single-quark propagators in the QGP as estimated from recent applications of heavy-quark rescattering to RHIC data.

description: This study takes as its point of departure the need to reform teaching practicum at the National University of Lesotho. It examines the literature devoted to the teaching practicum, identifying and appraising various models for the teaching practicum, and extracting principles for the conduct of the teaching practicum. The principles developed are then applied to the development of a framework for the teaching practicum at the National University of Lesotho. The study recommends a reflective inquiry approach in which student-teachers undertake a supervised teaching practicum and an induction year based upon a combination of Schon's model of a reflective teaching practicum and Zeichner's inquiry oriented teacher education.

description: We consider the color spin locking (CSL) phase of two-flavor quark matter at zero temperature for nonlocal instantaneous, separable interactions. We employ a Lorentzian-type form factor allowing a parametric interpolation between the sharp (Nambu-Jona-Lasinio (NJL) model) and very smooth (e.g. Gaussian) cut-off models for systematic studies of the influence on the CSL condensate the deviation from the NJL model entails. This smoothing of the NJL model form factor shows advantageous features for the phenomenology of compact stars: (i) a lowering of the critical chemical potential for the onset of the chiral phase transition as a prerequisite for stability of hybrid stars with extended quark matter cores and (ii) a reduction of the smallest pairing gap to the order of 100 keV, being in the range of values interesting for phenomenological studies of hybrid star cooling evolution.

description: Tubercles are modifications to the leading edge of an airfoil in the form of blunt wave-like serrations. Several studies on the effect of tubercles on isolated airfoils have shown a beneficial effect in the post-stall regime, as reduced drag and increased lift, leading to a delay of stall. The prospect of delaying stall is particularly attractive to designers of axial compressors in gas turbines, as this leads to designs with higher loading and therefore higher pressure rise with fewer number of stages. In the present study, experiments were performed on a cascade of airfoils with NACA 65209 profile with different tubercle geometries. The measurements were made over an exit plane using a five-hole probe to compare the cascade performance parameters. Additionally, hot-wire measurements were taken near the blade surface to understand the nature of the flow in the region close to the tubercles. Oil-flow visualization on the cascade end wall reveal the flow through the passage of blades with and without tubercles. For the cascade considered, the estimated stall angle for the best performing set of blades is found to increase up to 8.6° from that of the unmodified blade of 6.0°. Application of such structures in axial compressor blades may well lead to suppression of stall in axial compressors and extend the operating range.

description: The behavior of self driving cars may differ from people expectations, (e.g. an autopilot may unexpectedly relinquish control). This expectation mismatch can cause potential and existing users to distrust self driving technology and can increase the likelihood of accidents. We propose a simple but effective framework, AutoPreview, to enable consumers to preview a target autopilot potential actions in the real world driving context before deployment. For a given target autopilot, we design a delegate policy that replicates the target autopilot behavior with explainable action representations, which can then be queried online for comparison and to build an accurate mental model. To demonstrate its practicality, we present a prototype of AutoPreview integrated with the CARLA simulator along with two potential use cases of the framework. We conduct a pilot study to investigate whether or not AutoPreview provides deeper understanding about autopilot behavior when experiencing a new autopilot policy for the first time. Our results suggest that the AutoPreview method helps users understand autopilot behavior in terms of driving style comprehension, deployment preference, and exact action timing prediction.

description: This review serves as a concise introductory survey of modern compressive tomography developed since 2019. These are schemes meant for characterizing arbitrary low-rank quantum objects, be it an unknown state, a process or detector, using minimal measuring resources (hence compressive) without any \emph{a priori} assumptions (rank, sparsity, eigenbasis, \emph{etc}.) about the quantum object. This article contains a reasonable amount of technical details for the quantum-information community to start applying the methods discussed here. To facilitate the understanding of formulation logic and physics of compressive tomography, the theoretical concepts and important numerical results (both new and cross-referenced) shall be presented in a pedagogical manner.

description: This paper describes a Genetic Algorithms approach to a manpower-scheduling problem arising at a major UK hospital. Although Genetic Algorithms have been successfully used for similar problems in the past, they always had to overcome the limitations of the classical Genetic Algorithms paradigm in handling the conflict between objectives and constraints. The approach taken here is to use an indirect coding based on permutations of the nurses, and a heuristic decoder that builds schedules from these permutations. Computational experiments based on 52 weeks of live data are used to evaluate three different decoders with varying levels of intelligence, and four well-known crossover operators. Results are further enhanced by introducing a hybrid crossover operator and by making use of simple bounds to reduce the size of the solution space. The results reveal that the proposed algorithm is able to find high quality solutions and is both faster and more flexible than a recently published Tabu Search approach.

description: We study the formation of dark matter halos in the concordance LCDM model over a wide range of redshifts, from z=20 to the present. Our primary focus is the halo mass function, a key probe of cosmology. By performing a large suite of nested-box N-body simulations with careful convergence and error controls (60 simulations with box sizes from 4 to 256 Mpc/h, we determine the mass function and its evolution with excellent statistical and systematic errors, reaching a few percent over most of the considered redshift and mass range. Across the studied redshifts, the halo mass is probed over 6 orders of magnitude (10^7 - 10^13.5 M_sun/h). Historically, there has been considerable variation in the high redshift mass function as obtained by different groups. We have made a concerted effort to identify and correct possible systematic errors in computing the mass function at high redshift and to explain the discrepancies between some of the previous results. We discuss convergence criteria for the required force resolution, simulation box size, halo mass range, initial and final redshift, and time stepping. Because of conservative cuts on the mass range probed by individual boxes, our results are relatively insensitive to simulation volume, the remaining sensitivity being consistent with extended Press-Schechter theory. Previously obtained mass function fits near z=0, when scaled by linear theory, are in good agreement with our results at all redshifts, although a mild redshift dependence consistent with that found by Reed and collaborators exists at low redshifts.

description: We develop the general many-body perturbation theory for a superconducting quantum dot represented by a single-impurity Anderson model attached to superconducting leads. We build our approach on a thermodynamically consistent mean-field approximation with a two-particle self-consistency of the parquet type. The two-particle self-consistency leading to a screening of the bare interaction proves substantial for suppressing the spurious transitions of the Hartree-Fock solution. We demonstrate that the magnetic field plays a fundamental role in the extension of the perturbation theory beyond the weakly correlated $0$-phase. It controls the critical behavior of the $0-π$ quantum transition, lifts the degeneracy in the $π$-phase, where the limits to zero temperature and zero magnetic field do not commute. The response to the magnetic field is quite different in $0$- and $π$-phases. While the magnetic susceptibility vanishes in the $0$-phase it becomes of the Curie type and diverges in the $π$-phase at zero temperature.

description: We consider rare transitions induced by colored noise excitation in multistable systems. We show that undesirable transitions can be mitigated by a simple time-delay feedback control if the control parameters are judiciously chosen. We devise a parsimonious method for selecting the optimal control parameters, without requiring any Monte Carlo simulations of the system. This method relies on a new nonlinear Fokker-Planck equation whose stationary response distribution is approximated by a rapidly convergent iterative algorithm. In addition, our framework allows us to accurately predict, and subsequently suppress, the modal drift and tail inflation in the controlled stationary distribution. We demonstrate the efficacy of our method on two examples, including an optical laser model perturbed by multiplicative colored noise.

description: In this review, we discuss the present status of the description of confining flux tubes in SU(N) pure Yang-Mills theory in terms of ensembles of percolating center vortices. This is based on three main pillars: modelling in the continuum the ensemble components detected in the lattice, the derivation of effective field representations, and contrasting the associated properties with Monte Carlo lattice results. The integration of the present knowledge about these points is essential to get closer to a unified physical picture for confinement. Here, we shall emphasize the last advances, which point to the importance of including the nonoriented center-vortex component and non-Abelian degrees when modelling the center-vortex ensemble measure. These inputs are responsible for the emergence of topological solitons and the possibility of accommodating the asymptotic scaling properties of the confining string tension.

description: Σκοπός της διπλωματικής ήταν να φανούν οι στόχοι της εκπαίδευσης όπως προωθούνται από τους διεθνείς οργανισμούς και ο τρόπος με τον οποίο τους παρουσιάζουν οι τελευταίοι μέσα από τις διαφημίσεις τους. Για τον σκοπό αυτό αναλύθηκαν σημειωτικά δύο διαφημιστικά βίντεο των διεθνών οργανισμών UNESCO και UNICEF για την εκπαίδευση, ώστε να γίνει φανερός ο τρόπος άρθρωσης των δομών σημασίας σε γλώσσα και εικόνα. Αρχικά στην εργασία παρουσιάστηκαν οι γενικοί σκοποί της εκπαίδευσης και πώς αναπροσαρμόζονται στα πλαίσια της παγκοσμιοποίησης. Έγινε αναφορά στους διεθνείς οργανισμούς και τη σχέση τους με την εκπαίδευση. Στη συνέχεια παρουσιάστηκε εν συντομία η ρητορική της διαφήμισης και η σημειωτική μέθοδος, που υιοθετήθηκε για την ανάλυση των διαφημίσεων. Έπειτα παρουσιάστηκε η σημειωτική ανάλυση των διαφημίσεων των δύο διεθνών οργανισμών στο εικονικό, γραπτό και προφορικό τους κείμενο, η εξαγωγή συμπερασμάτων από την ανάλυση της κάθε διαφήμισης και η σύγκριση των συμπερασμάτων. Στο τελευταίο κεφάλαιο αναφέρονται τα γενικά συμπεράσματα, τα οποία αφορούν στα συγκριτικά δεδομένα ανάλυσης των τριών ειδών κειμένων (εικόνα, προφορική γλώσσα, γραπτή γλώσσα) με τους εκπαιδευτικούς στόχους των διεθνών οργανισμών, προκειμένου να αναδυθεί το είδος της σχέσης τους, ενώ αναφέρεται και ο τρόπος πειθούς των δύο βίντεο
description: The aim of the present thesis was to show the educational objectives as they are promoted by the international organizations and the way they are presented through their advertisements. For this purpose two TV commercials of UNESCO and UNICEF about education were semiotically analysed in order to show the utterance of meaning structures in language and image. Initially, the thesis presented the general aims of education and how they readapt due to globalization. There was a reference to the international organizations and their relation to education. Consequently rhetoric of the advertising and semiotic method which was used for the advertisement’s analysis were presented. Then the semiotic analysis of the two international organizations’ advertisements was presented in their iconic, written and spoken text, the deductions from the analysis of each advertisement and the conclusions’ comparison. In the last chapter the general conclusions are cited which have to do with the comparative analysis data of the three kinds of text (image, spoken language, written language) with the educational aims of the international organizations, in order to reveal the kind of their relation, while the means of persuasion of the two videos is also mentioned

description: Teleporting an unknown qubit state is a paradigmatic quantum information processing task revealing the advantage of quantum communication protocols over their classical counterpart. For a teleportation protocol using a Bell state as quantum channel, the resource has been identified to be the concurrence. However, for mixed multi-partite states the lack of computable entanglement measures has made the identification of the quantum resource responsible for this advantage more challenging. Here, by building on previous results showing that localizable concurrence is the necessary resource for controlled quantum teleportation, we show that any teleportation protocol using an arbitrary multi-partite state, that includes a Bell measurement, requires a non-vanishing localizable concurrence between two of its parties in order to perform better than the classical protocol. By first analyzing the GHZ channel and GHZ measurement teleportation protocol, in the presence of GHZ-symmetric-preserving noise, we compare different multi-partite entanglement measures with the fidelity of teleportation, and we find that the protocol performs better than the classical protocol when all multi-partite entanglement measures vanish, except for the localizable concurrence. Finally, we extend our proof to an arbitrary teleportation protocol with an arbitrary multi-partite entangled channel.

Ο τρόμος μέσα στον «Τρόμο»: Η επιρροή της Γαλλικής Επανάστασης στη λογοτεχνία, μέσα από την αφήγηση του Καλόγερου του Matthew Lewis και της Ζυστίν του Μαρκήσιου Ντε Σαντ

description: Μέσα από τη σύγκριση δύο λογοτεχνικών έργων του 18ου αιώνα, τη Ζυστίν του Μαρκήσιου Ντε Σαντ (1971) και τον Καλόγερο του Matthew Lewis, επιχειρούμε να εξετάσουμε τον τρόπο με τον οποίο η Γαλλική Επανάσταση και πιο συγκεκριμένα η «Βασιλεία του Τρόμου» του Μαξιμιλιανού Ροβεσπιέρου, επηρέασε τη λογοτεχνική παραγωγή σε Αγγλία και Γαλλία. Η έντονη κοινωνική ανησυχία και η πολιτική αναταραχή της εποχής συνδέονται με την άνοδο της γοτθικής λογοτεχνίας κατά την ίδια περίοδο, σε μια προσπάθεια να καθοριστεί ο βαθμός στον οποίο τα δύο έργα αντικατοπτρίζουν το επαναστατικό κλίμα της εποχής. Η εξέταση των δύο έργων και η ανάπτυξη της εργασίας βασίζονται σε ορισμένους κοινούς άξονες, όπως τον τρόμο, το λιμπερτινισμό, και τον αντι-καθολικισμό. Γίνεται επίσης αναφορά στη φιλοσοφία περί Φύσης, η οποία αναπτύσσεται λεπτομερώς στη Ζυστίν και στο υπερφυσικό στοιχείο, το οποίο συναντάμε στην αφήγηση του Lewis.
description: The present thesis attempts to determine the influence of the French Revolution and in particular Maximilien Robespierre’s “Reign of Terror”, on the literary works of England and France, through the comparison of two important works of the 18th century, Marquis De Sade’s Justine and Matthew Lewis’ The Monk. The social unrest and political uncertainty of that time are linked to the rise of the Gothic Novel in the same period, in order to determine the way in which the impact of the Revolution influenced the two narratives. The analysis of Justine and The Monk is based on three common themes the two narratives share: terror, libertinism and anti-Catholicism. There is also mention of De Sade’s natural philosophy and Lewis’ use of the supernatural, themes that the two authors do not share but are of paramount importance in their novels.
Joint work between ESL and subject-area teachers: a case study at the Secondary level
Creators: name: Helmer, Sylvia
Publisher: name: University of British Columbia
Year: 2009

description: This research documents how a group of secondary English as a Second Language (ESL) teachers attempted to work collaboratively with their subject-specialist peers for the benefit of ESL students. Using qualitative methods consistent with the case study strategy (Yin, 1989), this study describes and analyzes how the ESL teachers created and managed their new roles as teacher-collaborators (TCs) and how their subject specialist (ST) colleagues responded. In the process, the data also highlight seldom considered aspects of the medical model of consultation, upon which collaboration in schools is typically based. This research demonstrates that the medical model fails to capture important aspects of joint work within the educational context, including assumptions about who initiates and terminates contact, sets the agenda, and is responsible for implementing suggested or negotiated procedures. In addition, joint work in schools is shown to be further complicated by the need to take into consideration the pre-existing hierarchy of authority structures in institutional settings, and how these structures influence collaborative efforts. The TCs in this study could not move directly to fulfill their joint work mandate but had first to construct and establish the prerequisite components that could subsequently lead to joint work with their ST colleagues. This study has implications for both practitioners and researchers. Classroom teachers moving into joint work need to be given time and techniques to help them to develop an approach to such work which will allow them to continue to meet their professional responsibilities as they see them, while creating a common platform for working with their colleagues. This process should include careful examination of the underlying assumptions that are part of any joint work effort, as well as the negotiation of how these assumptions will be reconciled with the complex demands of the daily teaching agenda. Research needs to move beyond static models of joint work and develop dynamic models. These models will need to capture the processes by which the prerequisites for joint work are constructed through the use of institutional discourse within the context of the school.

Στη συνέχεια γίνεται αναφορά στις μεταφραστικές στρατηγικές που χρησιμοποιούμε παρουσιάζοντας τη μεθοδολογία της μεταφραστικής μας διαδικασίας, ακολουθεί το πρωτότυπο κείμενο και η μετάφρασή του στα ελληνικά, ένα γλωσσάρι με όρους του κειμένου και διεξοδική ανάλυση από επιλεγμένα ζητήματα μεταφραστικών προκλήσεων.
description: The aim of the present master thesis was to present the annotated translation into Greek of Dr. Alberto Ruz Lhuiler’s article, originally written in Spanish, titled La cerámica Maya. Desarrollo técnico y estilístico, according to the translation studies proposed by Kaindl. The aim of the project is through the annotated translation, to highlight in Greece how important was the civilization of Mayas and the area of Palenque, a southeast region of today’s Mexico, which was the cradle of their culture. From excavations in this area have been discovered findings that concern, among other things, sculptures, paintings and ceramics and will help scientists gather more information about various sectors of Maya’s society. In this master thesis, introductory reference is made to the content and version of the original text, the author and his work, and the culture of Mayas. Then reference is made in the translation strategies we use presenting the methodology of our translation progress, follows the original text and its translation into Greek language, a glossary of terms taken from the originally text and in depth analysis of selected issues of translation challenges.

description: A long debated issue concerning the nucleosynthesis of neutron-rich elements in Asymptotic Giant Branch (AGB) stars is the identification of the neutron source. We report intermediate-mass (4 to 8 solar masses) AGB stars in our Galaxy that are rubidium-rich owing to overproduction of the long-lived radioactive isotope 87Rb, as predicted theoretically 40 years ago. This represents a direct observational evidence that the 22Ne(alpha,n)25Mg reaction must be the dominant neutron source in these stars. These stars then challenge our understanding of the late stages of the evolution of intermediate-mass stars and would promote a highly variable Rb/Sr environment in the early solar nebula.
