description: Rhodamine B hydrazide and 2-chloroquinoline-3-carbaldehyde derivatives were used to synthesize novel colorimetric sensors for highly selective detection of copper ion. The measurement was based on the interaction between the synthesized ligands and Cu2+ and the sharp color change of the ligand from yellow to pink in the presence of Cu2+ ncrease in absorbance intensity at the new appeared absorbance peak was used as an analytical signal. The effect of parameters, such as time and sensor concentration were also investigated and discussed. The calibration curve was considered too under the optimum experimental conditions and was linear in the range 0.05– 5.00 μgmL-1. The interferences of some common ions were studied and the synthetic ligand was found to be a high selective sensor. Selectivity of the proposed method makes it as an applicable technique for the determination of copper in foodstuff samples.

description: We present a hierarchical equations of motion approach, which allows a numerically exact simulation of nonequilibrium transport in general open quantum systems involving multiple macroscopic bosonic and fermionic environments. The performance of the method is demonstrated for a model of a nanosystem, which involves interacting electronic and vibrational degrees of freedom and is coupled to fermionic and bosonic baths. The results show the intricate interplay of electronic and vibrational degrees of freedom in this nonequilibrium transport scenario for both voltage and thermally driven transport processes. Furthermore, the use of importance criteria to improve the efficiency of the method is discussed.

description: Η μετα-αλήθεια αποτελεί μία νέα πολιτική κουλτούρα, στην οποία η συζήτηση πλαισιώνεται από συναίσθημα, με προσπάθεια αποσύνδεσης από τις λεπτομέρειες της πολιτικής, αγνοώντας τις πραγματικές συγκρούσεις. Σε συνθήκες όπου τα αντικειμενικά γεγονότα έχουν μικρότερη επιρροή στη διαμόρφωση της κοινής γνώμης από τις επικλήσεις προς το θυμικό και προς τις προσωπικές απόψεις, η άσκηση της δημοσιογραφίας και ο ρόλος των δημοσιογράφων αποκτά μείζονα σημασία στην αποτύπωση των γεγονότων. Η παρούσα μελέτη ερευνά το φαινόμενο της πολιτικής της μετα-αλήθειας στη σύγχρονη δημοσιογραφία και τον ρόλο των δημοσιογράφων σε αυτό. Στόχος της εν λόγω έρευνας είναι η αποτύπωση της επιρροής που έχει το φαινόμενο της μετα-αλήθειας και των ψευδών ειδήσεων στα περιφερειακά Μέσα Μαζικής Ενημέρωσης, η καταγραφή των παραγόντων που επιδρούν στο αποτέλεσμα της εργασίας των δημοσιογράφων, η διατύπωση προτάσεων για την αντιμετώπιση του φαινομένου, αλλά και ο ρόλος των δημοσιογράφων στην περιχαράκωσή του.

description: Post-truth is a new political culture in which the discussion is framed by emotion, trying to disengage from the details of politics, ignoring real conflicts. In circumstances where objective facts have less influence on the formation of public opinion than appeals to the memory and personal opinions, the role of journalists is of major importance in capturing the facts. This study explores the phenomenon of post-truth politics in modern journalism and the role of journalists in it. The aim of this research is to capture the influence of the phenomenon of post-truth politics and fake news in the regional mass media, to record the factors that influence the work of journalists, to formulate proposals for dealing with the phenomenon, but also to imprint the role of journalists in the limitation of the phenomenon. In order to derive safe conclusions, the analysis of content in web pages of the Region of Western Macedonia, as well as interviews with professional journalists, were used as methodological tools. The results of the survey prove the influence of the phenomenon of post-truth in modern journalism, the lack of news/media literacy and the need to create new models of the media

This HTML document contains supplementary data for the journal article Exploratory study of sugar and C6 compounds in single berries of grapevine (Vitis vinifera L.) cv. Cabernet Sauvignon throughout ripening. Although the scope of the study was to explore the relationship between berry developmental stages and the composition of grapes, berry-to-berry variation at all developmental stages was found showing that each berry is ultimately following a singular ripening programme. Therefore, we considered it appropriate to provide data for each individual berry using interactive plots to support the data summary plots presented in the manuscript. The plotly package in R was used to produce interactive plots.

description: The Variable Density and Speed of Sound Vessel (VDSSV) produces subsonic turbulent flows that are both compressible and observable at all scales with existing instrumentation including hot wires and particle tracking. We realize this objective by looking at the flow of a heavy gas (sulfur hexafluoride $SF_6$), with a speed of sound almost three times lower than for air. By switching between air and $SF_6$, we isolate the influence of the turbulent Mach number (up to $M_t$ = 0.17) on turbulence statistics from the influences of changes in the Reynolds number (up to $R_λ$ = 1600), and boundary conditions, which we hold constant. A free shear flow is produced by a ducted fan, and we show that it behaves like a turbulent jet in that the mean velocity profiles approach self-similarity with increasing distance from the orifice (up to $x/D_f$ = 9). The jet responds like a compressible shear layer in that it spreads more slowly at higher Mach numbers (up to $M_j$ = 0.7) than at low Mach numbers. In contrast, the integral length scales and Kolmogorov constant of the turbulence are approximately invariant with respect to changes in either the Reynolds or Mach numbers. We briefly report on instrumentation under development that will extend the accessible Taylor-scale Reynolds and turbulent Mach numbers to 4000 and 0.3, respectively.

description: The SL(3,C)-representation variety R of a free group F arises naturally by considering surface group representations for a surface with boundary. There is a SL(3,C)-action on the coordinate ring of R. The geometric points of the subring of invariants of this action is an affine variety X. The points of X parametrize isomorphism classes of completely reducible representations. The coordinate ring C[X] is a complex Poisson algebra with respect to a presentation of F imposed by the surface. In previous work, we have worked out the bracket on all generators when the surface is a three-holed sphere and when the surface is a one-holed torus. In this paper, we show how the symplectic leaves corresponding to these two different Poisson structures on X relate to each other. In particular, they are symplectically dual at a generic point. Moreover, the topological gluing map which turns the three-holed sphere into the one-holed torus induces a rank preserving Poisson map on C[X].

description: Two-component coupled Bose gas in a 1D optical lattice is examined. In addition to the postulated Mott insulator and superfluid phases, multiple bosonic components manifest spin degrees of freedom. Coupling of the components in the Bose gas leads to substantial change in the previously observed spin phases, giving rise to new effective spin Hamiltonian and unraveling remarkable spin correlations. The system exhibiting ferromagnetic and non-ferromagnetic spin phases for on-site intra-component interaction stronger than inter-component interaction switches from first-order to second-order phase transition between the spin phases upon introduction of coupling, on which is dependent the transition width. For comparable on-site inter- and intra- component interaction, with coupling, instead of one, two spin phases emerge with a second-order phase transition. Exact diagonalization and Variational Monte Carlo (VMC) with stochastic minimization on Entangled Plaquette State (EPS) bestow a unique and enhanced perspective into the system beyond the scope of a mean-field treatment.

description: We present detailed numerical calculations of the fast solar tachocline based on the assumption that the dynamo field dominates over the dynamics of the tachocline. In the present paper of the series, we focus on three shortfalls of the earlier models. First, instead of the simple oscillating dipole poloidal field we study the more general magnetic field structures reminiscent of the butterfly diagram. The migrating field is prescribed as the observed axisymmetric radial magnetic field Stenflo (1988, 1994). Our results are in good agreement with our analitical estimate and our previous works in Forgacs-Dajka & Petrovay (2001,2002), but the polar "dip" in isorotational surfaces is strongly reduced in this case. On the other hand, a more realistic model should have a magnetic diffusivity decreasing significantly inside the radiative interior, so we also explore the effect of diffusivity and magnetic Prandtl number varying with depth. We found that the downwards decreasing magnetic diffusivity and Prandtl number have no significant effect on the solution, although the temporal variation of the tachocline thickness has decreased.

description: Background and rationale: Heart failure (HF), which is an emerging public health issue, adversely affects the strained health system in India. The potential adverse impact of HF on the economic well-being of affected individuals and their families is narrated in various anecdotal reports. Further, HF is known to push the affected individuals and their dependents into poverty. However, there is limited research quantifying how HF impacts the economic well-being of households from the low and middle-income countries. Methods: We describe the methods of a detailed economic impact assessment of HF at the household level in India. The economic impact study in HF is initiated across 20 centres in India. The selected centres represent different regions in India stratified based on the prevailing stage of epidemiological transition levels (ETLs). We will collect data from 1800 patients with acute decompensated HF and within 6-15 months of follow-up from the time of initial admission. The data that we intend to collect will consist of a) household healthcare expenditure including out-of-pocket expenditure, b) financing mechanisms used by households and (c) the impoverishing effects of health expenditures including distress financing and catastrophic health expenditure. Trained staff at each centre will collect relevant data by using a validated and structured interview schedule. The study will have 80% power, after accounting for five percent non-response rate, to test eight percent difference in primary outcome (proportion of families under distress financing) between different ETLs. Impact: The results from the study will help policy makers in understanding the micro-economic impact of HF in India and aid in allocation of appropriate resources for prevention and control of HF.

description: Background: Acute hospitals are increasingly the place where care is provided at end of life and the location of death. Providing care to the dying patient is a privilege; however there are many challenges to providing optimum care within this setting. Inconsistencies in knowledge and practice amongst nursing staff delivering end-of-life care have been identified. Due to a lack of standardised training; there are missed opportunities in caregiving for this group of patients. This has unfortunately resulted in a number of complaints by families following the death of a loved one in the acute hospital setting.Aim: The aim of this research study is to assess the knowledge, experience and educational needs of nursing staff caring for those at end of life within the acute hospital setting. The study aims to improve the quality of care delivered to patient’s who die in the acute hospital setting by introducing a standardised approach to education for all staff delivering end-of-life care.Methods: This study followed a co-operative inquiry action research design. Cycles of planning, action, observation, and reflection are demonstrated throughout the research process. The method of data collection for this study was a quantitative approach using an anonymous questionnaire. Further data was gathered from informal conversations and observation’s with nursing staff and recorded in a reflective diary.Results: An overarching finding from this study is the need for specific education in all aspects of care at end of life. Participants in this study identified the need for a structured support system to be implemented in order to enable them to deliver optimum end-of-life care following the death of a patient.Conclusions: Findings from this study contribute to our understanding and increase our knowledge of what is important for nursing staff caring for people at end of life. The findings from this study will be used to develop educational programmes which will enhance the care provided to both the person at end of life and those bereaved.

description: Improving the predictive capability of molecular properties in ab initio simulations is essential for advanced material discovery. Despite recent progress making use of machine learning, utilizing deep neural networks to improve quantum chemistry modelling remains severely limited by the scarcity and heterogeneity of appropriate experimental data. Here we show how training a neural network to replace the exchange-correlation functional within a fully-differentiable three-dimensional Kohn-Sham density functional theory (DFT) framework can greatly improve simulation accuracy. Using only eight experimental data points on diatomic molecules, our trained exchange-correlation networks enable improved prediction accuracy of atomization energies across a collection of 104 molecules containing new bonds and atoms that are not present in the training dataset.

description: One of the three X-ray detectors of the CAST experiment searching for solar axions is a Time Projection Chamber (TPC) with a multi-wire proportional counter (MWPC) as a readout structure. Its design has been optimized to provide high sensitivity to the detection of the low intensity X-ray signal expected in the CAST experiment. A low hardware threshold of 0.8 keV is safely set during normal data taking periods, and the overall efficiency for the detection of photons coming from conversion of solar axions is 62 %. Shielding has been installed around the detector, lowering the background level to 4.10 x 10^-5 counts/cm^2/s/keV between 1 and 10 keV. During phase I of the CAST experiment the TPC has provided robust and stable operation, thus contributing with a competitive result to the overall CAST limit on axion-photon coupling and mass.

description: We propose to use tensor diagrams and the Fomin-Pylyavskyy conjectures to explore the connection between symbol alphabets of $n$-particle amplitudes in planar $\mathcal{N}=4$ Yang-Mills theory and certain polytopes associated to the Grassmannian G(4, $n$). We show how to assign a web (a planar tensor diagram) to each facet of these polytopes. Webs with no inner loops are associated to cluster variables (rational symbol letters). For webs with a single inner loop we propose and explicitly evaluate an associated web series that contains information about algebraic symbol letters. In this manner we reproduce the results of previous analyses of $n \le 8$, and find that the polytope $\mathcal{C}^\dagger(4,9)$ encodes all rational letters, and all square roots of the algebraic letters, of known nine-particle amplitudes.

description: Voltage and dephasing probes introduce incoherent inelastic and incoherent quasi-elastic scattering into a coherent mesoscopic conductor. We discuss in detail the concepts of voltage and dephasing probes and develop a full counting statistics approach to investigate their effect on the transport statistics. The formalism is applied to several experimentally relevant examples. A comparison of different probe models and with procedures like phase averaging over an appropriate phase distribution shows that there is a perfect equivalence between the models for the case of one single-channel probe. Interestingly, the appropriate phase distribution function is found to be uniform. A uniform distribution is provided by a chaotic cavity with a long dwell time. The dwell time of a chaotic cavity plays a role similar to the charge response time of a voltage or dephasing probe. For multi-channel or multiple probes the transport statistics of voltage and dephasing probes differs and the equivalence with phase averaging is similarly lost.

description: We consider regularized support vector machines (SVMs) and show that they are precisely equivalent to a new robust optimization formulation. We show that this equivalence of robust optimization and regularization has implications for both algorithms, and analysis. In terms of algorithms, the equivalence suggests more general SVM-like algorithms for classification that explicitly build in protection to noise, and at the same time control overfitting. On the analysis front, the equivalence of robustness and regularization, provides a robust optimization interpretation for the success of regularized SVMs. We use the this new robustness interpretation of SVMs to give a new proof of consistency of (kernelized) SVMs, thus establishing robustness as the reason regularized SVMs generalize well.

description: The LandSense Citizen Observatory offers a wide breadth of citizen science and crowdsourcing approaches to address key questions within the domain of land use and land cover monitoring. Some of the LandSense pilots focused on in-situ observations using mobile apps, whereas other pilots were centered around satellite-image interpretations during dedicated mapathons. The design and implementation of the seven demonstration pilots across seven countries covering the urban, agriculture and forest habitat domains led to key discoveries and lessons learned by the consortium. We share stakeholder and volunteer feedback and provide a self-evaluation of all demonstration pilots, while addressing sustainability and further exploitation potential. This deliverable provides an overview of the LandSense demonstration cases in the urban, agriculture and forest habitat domains, each of which is described in more details in deliverables D4.5 (Demo 1: Cost reduction and data conflation in monitoring land change II), D4.6 (Demo 2: Monitoring agricultural land use and provision of value-added agricultural services II) and D4.7 (Demo 3: Forest and habitat monitoring using innovative technologies II). Each case is described, followed by a summary of the generic feedback gathered from experiences with running each case and an evaluation. The evaluation is based on the following criteria: • Number of users engaged • Number of downloads of the app; • Number of observations collected; • Uptake of the solution by local authorities, organizations, incorporation into business solutions; and • Other impacts. Although other LandSense KPIs were formulated to monitor and evaluate the LandSense project as a whole (available in the third Period Technical Report), these aforementioned measures, in particular, represent a way to reflect on the performance of each demonstration case. This is followed by recommendations arising from this evaluation for future citizen observatories on land use and land cover (LULC).

description: I summarize the arguments that strongly suggest that our universe is the product of inflation. The mechanisms that lead to eternal inflation in both new and chaotic models are described. Although the infinity of pocket universes produced by eternal inflation are unobservable, it is argued that eternal inflation has real consequences in terms of the way that predictions are extracted from theoretical models. The ambiguities in defining probabilities in eternally inflating spacetimes are reviewed, with emphasis on the youngness paradox that results from a synchronous gauge regularization technique. Although inflation is generically eternal into the future, it is not eternal into the past: it can be proven under reasonable assumptions that the inflating region must be incomplete in past directions, so some physics other than inflation is needed to describe the past boundary of the inflating region.

description: Hadronic matrix elements of local four-quark operators play a central role in non-leptonic kaon decays, while vacuum matrix elements involving the same kind of operators appear in inclusive dispersion relations, such as those relevant in $τ$-decay analyses. Using an $SU(3)_L\otimes SU(3)_R$ decomposition of the operators, we derive generic relations between these matrix elements, extending well-known results that link observables in the two different sectors. Two relevant phenomenological applications are presented. First, we determine the electroweak-penguin contribution to the kaon CP-violating ratio $\varepsilon'/\varepsilon$, using the measured hadronic spectral functions in $τ$ decay. Second, we fit our $SU(3)$ dynamical parameters to the most recent lattice data on $K\toππ$ matrix elements. The comparison of this numerical fit with results from previous analytical approaches provides an interesting anatomy of the $ΔI = \frac{1}{2}$ enhancement, confirming old suggestions about its underlying dynamical origin.

description: This project seeks to address the problem of the future of industrial ruins / cities within the larger context of the US rust belt. Many of these Rust Belt cities face challenges of decaying infrastructure, overburdened social services, population loss, increased crime, and pronounced civil decline. This thesis seeks to find a program or architectural intervention that capitalizes on abandoned industrial buildings that can be seen as catalysts for revitalization.

The city of Johnstown will be examined as it has many of the key traits of a rust belt city. The architectural response to these set of problems must manifest at the regional, city, and site scale to address the question of whether such interventions in Johnstown can serve as models or catalysts for new industries, alternate uses, identity, social structure, improve quality of life, and an embodiment community ideals? The industrial ruins in rust belt cities are the embodiment of political decisions, social circumstances, economic factors and unique architectural features. Any intervention must address these embodied forces in order to create a viable transformation and to make Johnstown a showcase of what these places could be.

description: The edge between city + water has become a divide. This thesis addresses

this edge that has been thickened by abandoned industry and challenges the

way we design for our changing waterfronts through a design approach

relying on specificity of place. The design proposal shows how the water/city

divide can become a connective threshold, how industrial landscapes can be

reclaimed, and how this place-specific investigation can be an example to

learn from through Westchester County’s Hudson River Waterfront, the City

of Yonkers, and the abandoned Glenwood Power Plant. This method has

resulted with the integration of building into landscape so that it acts as part of

a new infrastructure which cleans water, supports urban agriculture, and

provides recreational and training opportunities for the surrounding

community. Flows have been re-purposed to knit connections in all axes, and

begin to heal water’s edge.

description: Στην εργασία αυτή χρησιμοποιήσαμε δύο σειρές δειγμάτων. Η πρώτη σειρά είναι τα δείγματα PbTe-x% CdTe-0.055% PbI2 (x=1, 3, 5, 7, 10) και η δεύτερη τα δείγματα SrxPb1+xTe+1%Na2Te (x=0.01, 0.02, 0.03, 0.04, 0.05). Τα δείγματα αυτά τα υποβάλλαμε σε διάφορες τεχνικές μέτρησης. Έχουμε δύο συστήματα PbTe - CdTe και PbTe - SrTe. Τα δυο συστήματα (PbTe - CdTe & PbTe - SrTe) είναι ντοπαρισμένα με διαφορετική πρόσμιξη (dopant, PbI2 & Na2Te), που σημαίνει ότι το ένα (PbTe - CdTe) είναι n - τύπου (n – type), ενώ το άλλο (PbTe - SrTe) είναι p - τύπου (p – type). Τόσο το CdTe όσο και το SrTe βρίσκονται στα δυο συστήματα με δυο μορφές: α) στο ποσοστό που διαλύεται στη μήτρα ως CdxPb1-xTe ή SrxPb1+xTe, δηλαδή ως στερεό διάλυμα (solid solutions), οπότε λειτουργούν ως ρυθμιστές των ζωνών (band modifiers, band - engineering) στη μήτρα PbTe (αυξάνουν το Eg), β) ως καθαρά εγκλείσματα, οπότε (πέρα από τη μείωση στη θερμική αγωγιμότητα πλέγματος, που δεν μετρήσαμε) λειτουργούν ως εμπόδια (energy barriers) για τους φορείς μειονότητας (minority - carrier filtering), λόγω της μεγάλης διαφοράς στο Eg μεταξύ του μητρικού συστήματος (PbTe - CdTe ή PbTe - SrTe) και των εγκλεισμάτων (CdTe ή SrTe).
description: In this study we used two sets of samples. The first system is PbTe-x% CdTe-0.055% PbI2 (x = 1, 3, 5, 7, 10) and the second is SrxPb1+xTe+1% Na2Te (x = 0.01, 0.02, 0.03, 0.04, 0.05). The samples subjected to various different measuring techniques. We have two systems (PbTe-CdTe and PbTe-SrTe). These two systems (PbTe-CdTe & PbTe-SrTe) are doped with a different dopant (PbI2 & Na2Te), which means that one (PbTe-CdTe) is n-type while the other one (PbTe-SrTe) is p-type. Both CdTe and SrTe are found in these systems in two forms: α) The fraction x that dissolves in the matrix as CdxPb1-xTe or SrxPb1-xTe, as solid solutions, thereby as band modifiers (band-engineering) in PbTe matrix (increase Eg), β) Net inclusions, so (aside from reducing the thermal lattice conductivity, not measured) they are working as energy barriers for minority carriers (minority-carrier filtering), due to the large difference in Eg between the matrix system (PbTe-CdTe or PbTe-SrTe) and inclusions (CdTe or SrTe).

description: In this work, based on the Fredkin spin chain, we introduce a family of spin-$1/2$ many-body Hamiltonians with a three-site interaction featuring a fragmented Hilbert space with coexisting quantum many-body scars. The fragmentation results from an emergent kinetic constraint resembling the conserved spin configuration in the 1D Fermi-Hubbard model in the infinite onsite repulsion limit. To demonstrate the many-body scars, we construct an exact eigenstate that is in the middle of the spectrum within each fractured sub-sector displaying either logarithmic or area-law entanglement entropy. The interplay between fragmentation and scarring leads to rich tunable non-ergodic dynamics by quenching different initial states that is shown through large scale matrix product state simulations. In addition, we provide a Floquet quantum circuit that displays non-ergodic dynamics as a result of sharing the same fragmentation structure and scarring as the Hamiltonian.

CO line width and the black hole -- bulge relationship at high redshift
Creators: name: Wu, Xue-Bing
Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Recently, it has been suggested that the CO line width (FWHM(CO)) is a surrogate for the bulge velocity dispersion ($σ$) of the host galaxies of high-redshift quasars, and the black hole -- bulge ($M_{BH}-σ$) relation obtained with this assumption departs significantly from the $M_{BH}-σ$ relation in the local universe. In this study, we first present an investigation of the correlation between the CO line width and the bulge velocity dispersion using a sample of 33 nearby Seyfert galaxies. We find that the formula adopted in previous studies, $σ=\rm{FWHM(CO)}/2.35$, is generally not a good approximation. Using it, one may underestimate the value of bulge velocity dispersion significantly when the CO line is narrower than 400 $km s^{-1}$. By involving the galactic inclination angle $i$ as an additional parameter, we obtain a tight correlation between the inclination-corrected CO line width and the bulge velocity dispersion, namely, $\rm {FWHM(CO)}/\sin i=-67.16\pm80.18+(3.62\pm0.68)σ$. Using this new relation, we can better estimate the bulge velocity dispersion from the CO line width if the galactic inclination is known. We apply this new relation to nine high-redshift quasars with CO line detections and find that they are consistent with the local $M_{BH}-σ$ relation if their inclination angles are around $15^o$. The possible smaller inclinations of the high-redshift quasars are preferred because of their relatively greater likelihood of detection, and are also consistent with their relatively smaller CO line widths compared to submillimeter galaxies (SMGs) at high redshift having a similar total amount of molecular gas. Future observations are needed to confirm these results.

description: Η παρούσα εργασία πραγματεύεται την ετυμολογία της Αθλητιατρικής ορολογίας, αγγλοσαξονικής και ελληνικής και γίνεται μια προσπάθεια συσχέτισής τους. Χωρίζεται σε δύο μέρη στο θεωρητικό και στο πρακτικό. Στο πρώτο μέρος της εργασίας γίνεται μια σύντομη ιστορική ανασκόπηση και στη συνέχεια επιχειρείται ο ορισμός των βασικών όρων της εργασίας (Αθλητιατρική επιστήμη, ορολογία, ετυμολογία). Στο δεύτερο μέρος της εργασίας που αποτελεί τον κύριο σκοπό της εργασίας, γίνεται η ανάλυση των αγγλοσαξονικών λέξεων από ενδεικτικούς τομείς της Αθλητιατρικής επιστήμης και επιχειρείται η ετυμολογία τους στα ελληνικά. Πιο συγκεκριμένα, οι λέξεις που επιλέγονται από κάθε τομέα, καθώς και η ομαδοποίησή τους ως προς τους θεματικούς τομείς στους οποίους γίνεται η ταξινόμηση των λέξεων είναι ενδεικτικές, διότι η Αθλητιατρική ορολογία δεν περιλαμβάνει μόνο έναν επιστημονικό κλάδο, αλλά ένα ευρύ φάσμα επιστημονικών πεδίων. Στο τέλος της εργασίας παρουσιάζονται τα συμπεράσματα, όπου επαληθεύεται η βασική υπόθεση της εργασίας ότι η αγγλική Αθλητιατρική ορολογία έχει της ρίζες της στην ελληνική γλώσσα.
description: The present paper discusses the etymology of Sports Medicine terminology of Anglo-Saxon and Greek language and an attempt is being made to relate them. It is divided in two parts, in theoretical and in practical. In the first part of the paper it is being made a brief historical overview and then it is attempted the definition of the basic terms of this paper (Sports Medicine science, terminology, etymology). It the second part of this paper which is the main point of this thesis, it is being made analysis of Anglo-Saxon words from indicative sectors of Sports Medicine science and it is being made their etymology in the Greek language. In particular, words which have been chosen from each field, as well as their grouping in the subject areas in which words are classified, are indicative, because Sports Medicine terminology includes not only a scientific field but a wide range of it. At the end of this paper there are presented the conclusions, where the basic hypothesis of this thesis is verified, which says that English Sports Medicine terminology has its roots in the Greek language.

description: The given coexistence in high school classes of children of Greek and non-Greek origin has raised questions that triggered the investigation of educational needs in bilingualism conditions in integration classes. The purpose of the study is to investigate the over-representation of Albanian children in integration classes of the second year of Junior high school. In particular, the questions to be explored as they arise from the theoretical framework are as follows: Is there still a tendency for Albanian students to be placed into integration classes based mainly on bilingualism? To what extent are teachers' representations for children of Albanian origin related to low academic performance? Does the placement of children in an integration class take place after exploring the child's history, taking into account the specificities of the Albanian language and the background of the child? The methodology followed was quantitative research and the findings were commented and analyzed.
