description: Αντικείμενο της διατριβής ήταν ένας από τους βασικότερους λόγους για τους οποίους μια δικαστική απόφαση πολιτικού δικαστηρίου προσβάλλεται με αναίρεση και συγκεκριμένα αυτός που προβλέπεται στο άρθρο 559 αρ.1 του Κώδικα Πολιτικής Δικονομίας. Ο προαναφερόμενος λόγος αναίρεσης έχει προβλεφθεί για τις περιπτώσεις κατά τις οποίες ο εφαρμοστής του δικαίου υποπίπτει σε σφάλματά κατά την απονομή της δικαιοσύνης. Ειδικότερα, όταν παραβιάζει κάποιο κανόνα ουσιαστικού δικαίου είτε επειδή προβαίνει σε ψευδή ερμηνεία του εφαρμοζόμενου κανόνα δικαίου είτε επειδή κατά την αξιολόγηση των πραγματικών περιστατικών προβαίνει σε εσφαλμένη υπαγωγή τους στον εφαρμοζόμενο κανόνα δικαίου, τότε ο διάδικος δικαιούται να προσφύγει στο Ανώτατο Ακυρωτικό για να αποκατασταθεί το δίκαιο και να ικανοποιήσει τις ιδιωτικές του απαιτήσεις. Η παρούσα διατριβή παρουσιάζει αναλυτικά τις ειδικότερες εκφάνσεις του ανωτέρω αναιρετικού λόγου στην ελληνική νομολογία, τις διατυπωθείσες θεωρητικές θέσεις και τις προβληματικές κάθε ειδικότερου ζητήματος.
description: Subject matter of the present thesis is one of the most common grounds of appeal, invoked before the Supreme Court of Justice, in particular the one provided for in article 559 n.1 of the Greek Code of Civil Procedure. The aforementioned ground of appeal is provided for those cases where the Judge who applies the law commits an error when adjudicating. More precisely, when the judge violates a section of the Greek Civil Law either because he falsely construes the applicable rule of law or because during the evaluation of the facts he falsely applies them to the applicable rule of law, the litigant has the right to appeal against the judicial decision before the Supreme Court of Justice in order for justice to be done and to have this civil claim satisfied. This thesis elaborately presents the particular aspects pf the foregoing ground of appeal in the Greek jurisprudence, the theoretical approach by the legal academia as well as the issues arising out of each particular matter.

description: Οι Ντονμέ ή Μαμινίμ ήταν μια εθνοθρησκευτική κοινότητα με μακραίωνη παρουσία στη Θεσσαλονίκη από τα μέσα του 17ου αιώνα μέχρι το πρώτο τέταρτο του 20ου αιώνα. H κοινότητα δημιουργήθηκε από Σεφαραδιτές Εβραίους που ακολούθησαν τις διδαχές του ραββίνου Σαμπατάι Σεβί και εξισλαμίστηκαν εθελούσια.Οι Ντονμέ διαμόρφωσαν και διατήρησαν μια ξεχωριστή εθνοθρησκευτική ταυτότητα, που τους διέκρινε από τις υπόλοιπες κοινότητες της πόλης. Τα μέλη της κοινότητας δραστηριοποιήθηκαν σε κάθε τομέα της πολιτικής,οικονομικής και κοινωνικής της ζωής. Επιφανείς Ντονμέ συμμετείχαν στον αστικό εκσυγχρονισμό της Θεσσαλονίκης στα τέλη του 19ου αι. Οι Μαμινίμ εντάχθηκαν μαζικά στις νεοτουρκικές οργανώσεις της πόλης και στήριξαν σθεναρά την Νεοτουρκική Επανάσταση του 1908. Μετά την προσάρτησή της πόλης από το ελληνικό κράτος το 1912 επιδίωξαν, επιστρατεύοντας διάφορους τρόπους,να παραμείνουν στην πατρίδα τους. Ωστόσο, οι εξαιρετικά δυσμενείς συνθήκες που επικράτησαν μετά την καταστροφική πυρκαγιά του 1917 και κυρίως την έκβαση του ελληνικο-τουρκικού πολέμου του 1919-1922 τους υποχρέωσαν να εγκαταλείψουν οριστικά την γεννέτειρα πόλη τους το 1923-4, σύμφωνα με την σύμβαση ανταλλαγής πληθυσμών της Λωζάννης του 1923.
description: Donme or Maminim were an ethnoreligious community with longstanding presence in Thessaloniki from the middle of 17th Century until the first quarter of the 20nd Century. The community was created by Sepharad-Jews who followed the teachings of the rabbi Sabbatai Sevi and converted in Islam voluntarily. Donme developed and maintained a unique ethnoreligious identity which differentiated them from the other communities of the city. Τhe members of the community became active in every sector of city’s political, financial and social life.Notable Donme took an active part in its urban modernization that took place in the end of the 19th CE.Maminim joined en masse the local Youngturk organizations and stongly supported the Youngturk revolution. After the city’s annexation to Greece in 1912, they pursued leving many ways to remain in their homeland. Ηowever, the extremely unfavourable conditions which prevailed after the destructive fire of 1917 and especially after the Greek-Turkish War of 1919-1922 forced them to abandon their native city permanently in 1923-4, according to the population-exchange treaty of Lausagne, signed in 1923.

UV Extinction as a More Fundamental Measure of Dust than E(B-V) or A(V)

description: The gas-to-dust ratio of reddened stars in the Milky Way (MW), the Magellanic Clouds, and in general is usually expressed as a linear relation between the hydrogen column density, N(H), and the reddening, E(B-V), or extinction in the V band (A(V)). If the extinction curve was truly universal, the strength of the relationship and the linearity would naturally be maintained for extinction at any wavelength, and also for N(H) vs. E(B-V). However, extinction curves vary within the Milky Way, and there is no reason why, except by chance, either E(B-V) or A(V) would be the most physical measure of dust column density. In this paper, we utilize for the first time full extinction curves to 41 MW sightlines and find that the scatter between N(H) and extinction is minimized -- and the relation becomes linear -- for extinction at 2900 +/- 160 A. Scatter and nonlinearity increase at longer wavelengths and are especially large for near-IR extinction. We conclude that near-UV extinction is a superior measure of the dust column density for MW dust. We provide new, non-linear gas-to-dust relations for various dust tracers. We also find that the very large discrepancy between MW and SMC gas-to-dust ratios of 0.9 dex in N(H)/E(B-V) is reduced to 0.7 dex for far-UV extinction, which matches the difference in cosmic abundances of carbon between the two galaxies, and therefore confirms that N(C) is the preferred measure of the gas in the gas-to-dust ratio, even though it may not be a convenient one.

The value 1 problem for concurrent mean-payoff games
Creators: name: Chatterjee, Krishnendu

Year: 2014
Subjects: 000 Computer science, knowledge & general works

description: We consider concurrent mean-payoff games, a very well-studied class of two-player (player 1 vs player 2) zero-sum games on finite-state graphs where every transition is assigned a reward between 0 and 1, and the payoff function is the long-run average of the rewards. The value is the maximal expected payoff that player 1 can guarantee against all strategies of player 2. We consider the computation of the set of states with value 1 under finite-memory strategies for player 1, and our main results for the problem are as follows: (1) we present a polynomial-time algorithm; (2) we show that whenever there is a finite-memory strategy, there is a stationary strategy that does not need memory at all; and (3) we present an optimal bound (which is double exponential) on the patience of stationary strategies (where patience of a distribution is the inverse of the smallest positive probability and represents a complexity measure of a stationary strategy).

description: Connecting the composition of planet-forming disks with that of gas giant exoplanet atmospheres, in particular through C/O ratios, is one of the key goals of disk chemistry. Small hydrocarbons like $\rm C_2H$ and $\rm C_3H_2$ have been identified as tracers of C/O, as they form abundantly under high C/O conditions. We present resolved $\rm C_3H_2$ observations from the TW Hya Rosetta Stone Project, a program designed to map the chemistry of common molecules at $15-20$ au resolution in the TW Hya disk. Augmented by archival data, these observations comprise the most extensive multi-line set for disks of both ortho and para spin isomers spanning a wide range of energies, $E_u=29-97$ K. We find the ortho-to-para ratio of $\rm C_3H_2$ is consistent with 3 throughout extent of the emission, and the total abundance of both $\rm C_3H_2$ isomers is $(7.5-10)\times10^{-11}$ per H atom, or $1-10$% of the previously published $\rm C_2H$ abundance in the same source. We find $\rm C_3H_2$ comes from a layer near the surface that extends no deeper than $z/r=0.25$. Our observations are consistent with substantial radial variation in gas-phase C/O in TW Hya, with a sharp increase outside $\sim30$ au. Even if we are not directly tracing the midplane, if planets accrete from the surface via, e.g., meridonial flows, then such a change should be imprinted on forming planets. Perhaps interestingly, the HR 8799 planetary system also shows an increasing gradient in its giant planets' atmospheric C/O ratios. While these stars are quite different, hydrocarbon rings in disks are common, and therefore our results are consistent with the young planets of HR 8799 still bearing the imprint of their parent disk's volatile chemistry.

description: We explore via linearized perturbation theory the Gregory-Laflamme instability of rotating black strings with equal magnitude angular momenta. Our results indicate that the Gregory-Laflamme instability persists up to extremality for all even dimensions between six and fourteen. We construct rotating nonuniform black strings with two equal magnitude angular momenta in six dimensions. We see a first indication for the occurrence of a topology changing transition, associated with such rotating nonuniform black strings. Charged nonuniform black string configurations in heterotic string theory are also constructed by employing a solution generation technique.

Συγκρίναμε τις πολιτικές διαφημίσεις πριν και μετά την κρίση και προσπαθήσαμε να εντοπίσουμε διαφορές μεταξύ αυτών των δύο περιόδων. Αρκετά ενδιαφέροντα συμπεράσματα προέκυψαν από την έρευνα, όπως ότι το συναίσθημα της ελπίδας έχει αυξηθεί σημαντικά από την κρίση και μετά.
description: The survey includes 584 TV political advertisements from 2004 to 2016 in Greece (National and European elections). We examined the type of advertising and the emotional appeal (hope, fear, pride, etc.) of these advertisements. Study reference point was the financial crisis of 2010. We compared the political ads before and after the crisis and we tried to identify differences between these two periods. Several interesting findings emerged from the research such as the feeling of hope has been greatly increased since the crisis.

description: Axial octupole and tetrahedral correlations in $^{80}$Zr and $^{98}$Zr have been investigated using the generator coordinate method, applied to a basis generated by Skyrme HF+BCS calculations. We focus on the possible presence of states with tetrahedral symmetry and their stability with respect to octupole vibrations. We show that pairing significantly reduces the stability of the tetrahedral configuration and that a shallow mean-field tetrahedral minimum coexists with an axial octupole minimum. The contributions to the correlation energies coming from the tetrahedral degree of freedom and octupole axial deformation are discussed.

description: The new members of the charm-strange family $D_{sJ}^{*}(2317)$, $D_{sJ}(2460)$ and $D_s(2632)$, which have the surprising properties, are challenging the present models. Many theoretical interpretations have been devoted to this issue. Most of authors suggest that they are not the conventional $c\bar s$ quark model states, but possibly are four-quark states, molecule states or mixtures of a P-wave $c\bar s$ and a four-quark state. In this work, we follow the four-quark-state picture, and study the masses of $cn\bar n\bar s/cs\bar s\bar s$ states ($n$ is $u$ or $d$ quark) in the chiral SU(3) quark model. The numerical results show that the mass of the mixed four-quark state ($cn\bar n\bar s/cs\bar s\bar s$) with spin parity $J^P=0^{+}$ might not be $D_s(2632)$. At the same time, we also conclude that $D_{sJ}^{*}(2317)$ and $D_{sJ}(2460)$ cannot be explained as the pure four-quark state.

description: This study aims to investigate the chloride diffusion behavior of alkali activated slag and fly ash blends with different contents of waste glass powder (GP) addition. The reaction heat flow of alkali activated slag/fly ash/waste glass is characterized. The reaction products are determined by X-ray diffraction and thermogravimetric analysis (TGA). N2 adsorption analysis (BET) is used to evaluate the microstructure of samples. The accelerated chloride penetration test (ACPT) is applied to study the chloride resistance of the AAMs. Subsequently, the leaching test of chloride penetrated samples are conducted and ion chromatography is utilized to measure the chloride content in the samples. According to the BET results, the total volume of mesopores decreases with increasing GP content. The results of ACPT show that the increasing GP in AAMs shows an enhancement of chloride resistance.

description: Measuring the population of obscured quasars is one of the key issues to understand the evolution of active galactic nuclei (AGNs). With a redshift completeness of 99%, the X-ray sources detected in Chandra Deep Field South (CDF-S) provide the best sample for this issue. In this letter we study the population of obscured quasars in CDF-S by choosing the 4 -- 7 keV selected sample, which is less biased by the intrinsic X-ray absorption. The 4 -- 7 keV band selected samples also filter out most of the X-ray faint sources with too few counts, for which the measurements of N_H and L_X have very large uncertainties. Simply adopting the best-fit L_2-10keV and N_H, we find 71% (20 out of 28) of the quasars (with intrinsic L_2-10keV > 10^44 erg/s) are obscured with N_H > 10^22 cm^-2. Taking account of the uncertainties in the measurements of both N_H and L_X, conservative lower and upper limits of the fraction are 54% (13 out 24) and 84% (31 out 37). In Chandra Deep Field North, the number is 29%, however, this is mainly due to the redshift incompleteness. We estimate a fraction of ~ 50% - 63% after correcting the redshift incompleteness with a straightforward approach. Our results robustly confirm the existence of a large population of obscured quasars.

description: We report a scanning superconducting quantum interference device (SQUID) microscope in a cryogen-free dilution refrigerator with a base temperature at the sample stage of at least 30 mK. The microscope is rigidly mounted to the mixing chamber plate to optimize thermal anchoring of the sample. The microscope housing fits into the bore of a superconducting vector magnet, and our design accommodates a large number of wires connecting the sample and sensor. Through a combination of vibration isolation in the cryostat and a rigid microscope housing, we achieve relative vibrations between the SQUID and sample that allow us to image with micrometer resolution over a 150 $μ$m range while the sample stage temperature remains at base temperature. To demonstrate the capabilities of our system, we show images acquired simultaneously of the static magnetic field, magnetic susceptibility, and magnetic fields produced by a current above a superconducting micrometer-scale device.

description: Τα κοινωνικά μέσα δικτύωσης έχουν πλέον εισαχθεί στη ζωή των ανθρώπων και η αυξημένη χρήση των συγκεκριμένων πλατφορμών δημιουργεί πολλούς νέους δρόμους επικοινωνίας, καθώς παίζουν κεντρικό ρόλο στις δραστηριότητες τους, στα κοινωνικά φαινόμενα στην οικονομική και πολιτική ζωή. Οι εταιρίες συχνά αργούν να βρουν τον τρόπο με τον οποίο θα αξιοποιήσουν μια νέα τεχνολογία. Παρότι ορισμένοι εργαζόμενοι όντως κάνουν άσκοπες εργασίες άλλοι ανακάλυψαν τρόπους να αξιοποιήσουν τη δύναμη των Κοινωνικών Μέσων Δικτύωσης. Σκοπός της εργασίας είναι η σωστή καθοδήγηση των επιχειρήσεων και των εργαζομένων αυτών ως προς των τρόπο που τα ΚΜΔ θα γίνουν εργαλείο απόκτηση επιχειρησιακού πλεονεκτήματος.

description: The German Environment Agency (UBA) funded the project “Influence of a major airport on temporal and spatial distributions of outdoor air concentrations of ultrafine dust <100 nm to describe the potential exposure in the vicinity - including other air pollutants (soot, nitrogen oxides and particulate matter (PM2.5 and PM10))”, UFOPLAN 3716 52 200 0. Total UFP number concentration for the year 2015 at and around Frankfurt Airport (FRA) was estimated using a combination of established small-scale (LASAT/LASPORT) and large-scale modelling (EURAD, MADE). Emissions were determined for aircraft traffic, road traffic, airport ground services and regional/mesoscale background using standard national and international inventories (HBEFA, ICAO, GRETA) and specific data obtained from the airport. Model outputs were series of successive 3-dimensional hourly mean concentrations apportioned to aircraft, airport, motor traffic and background. The model results suggest that aircraft main engines are the dominant source of UFP at the airport. Aircraft up to 3’000 ft (about 230’000 LTOs) plus airport-bound sources yield an annual nvPM emission of 1e+24 particles, about 90% of which are due to aircraft main engines. According to the model results, long-time averages of UFP number concentration are dominated by background contributions at locations further away from the airport, while the airport contribution to hourly mean concentrations can be significant even in some distance from the airport. An important aim of the project was to identify shortcomings of current state-of-the-art emission and concentration modelling of UFP in the context of airports. Here, inconsistent UFP diameter ranges in the databases, models and measurements are of relevance, likewise differences in the considered UFP characterisation and measuring method, in particular volatile versus non-volatile fractions. On a more advanced level, current limitations in knowledge and capabilities of local models to address UFP transformation processes play a role.

description: We show that six-dimensional backgrounds that are T^2 bundle over a Calabi-Yau two-fold base are consistent smooth solutions of heterotic flux compactifications. We emphasize the importance of the anomaly cancellation condition which can only be satisfied if the base is K3 while a T^4 base is excluded. The conditions imposed by anomaly cancellation for the T^2 bundle structure, the dilaton field, and the holomorphic stable bundles are analyzed and the solutions determined. Applying duality, we check the consistency of the anomaly cancellation constraints with those for flux backgrounds of M-theory on eight-manifolds.

description: Σκοπός της διατριβής ήταν η μελέτη των νομικών ζητημάτων που αφορούν την έρευνα, εξόρυξη, παραγωγή και εκμετάλλευση των υδρογονανθράκων στα πλαίσια του διεθνούς δικαίου. Αρχικά εξετάσαμε το ιδιοκτησιακό καθεστώς των κοιτασμάτων υδρογονανθράκων στο Διεθνές Δημόσιο Δίκαιο, τόσο των χερσαίων όσο και των θαλάσσιων, αλλά και τις γενικές αρχές του ζητήματος. Επιπρόσθετα αναλύσαμε τα παραπάνω ζητήματα τόσο με βάση το διεθνές εθιμικό δίκαιο, όπως επίσης με βάση τις διεθνείς συμβάσεις και την αντίστοιχη νομολογία. Το βασικό μας ζήτημα ήταν η κρατική κυριαρχία επί των πλουτοπαραγωγικών πηγών. Η παραπάνω ανάλυση μας οδήγησε άμεσα στο βασικό μας ζήτημα, δηλαδή την από κοινού ανάπτυξη διασυνοριακών κοιτασμάτων υδρογονανθράκων ή κοιτασμάτων σε αμφισβητούμενες περιοχές από κράτη και διεθνείς πετρελαϊκές εταιρείες. Το δεύτερο ζήτημα, ήταν η ανάθεση συμβάσεων, δηλαδή η διαδικασία παραχώρησης δικαιωμάτων έρευνας, εξόρυξης, παραγωγής και εκμετάλλεσυης υδρογονανθράκων στις διεθνείς πετρελαϊκές εταιρείες. Με αυτόν τον τρόπο συνδέσαμε το καθεστώς ιδιοκτησίας και τις μεθόδους ανάθεσης, με σκοπό την ανάπτυξη των κοιτασμάτων υδρογονανθράκων. Τέλος μελετήσαμε τις συμβάσεις που υπογράφονται μετά το τέλος της διαδικασίας ανάθεσης, με σκοπό να διακρίνουμε τους διαφορετικούς τύπους συμβάσεων, τις ρήτρες και τα νομικά αποτελέσματα.
description: The purpose of this dissertation was to explore the legal issues of the upstream oil and gas sector in the international legal order. Firstly, we examined the ownership status of petroleum reserves under Public International Law, both onshore and offshore and the general principles surrounding this subject. Furthermore, we analyzed the aforementioned issues in light of customary international law, which plays a fundamental role in the subject, as well as the relevant treaty law and cases. The main issue here is state sovereignty over its natural resources (sovereign ownership). This analysis directly presented us with the main legal issue, which is joint development of petroleum reserves by States and International Oil Companies in disputed or transboundary areas. Our second issue which is procurement, namely the procedure of awarding mineral rights by States (or via their National Oil Companies) to International Oil Companies. We connected ownership and the methods used by a State (or a group of States) for awarding petroleum rights, in order to develop its petroleum reserves. Finally, we studied contracts concluded after the procurement stage, with a view to distinguish the different types, clauses and legal results that each of them produce.

description: Jets, collimated outflows of particles and fields, are observed in a wide variety of astrophysical systems, including Active Galactic Nuclei of various types, microquasars, gamma-ray bursts, and young stellar objects. Despite intensive efforts along several decades of observational and theoretical research, there are still many uncertainties and open questions related to how jets are produced and what is their composition. In this review I offer an outline of some current views on the content and basic properties of astrophysical jets.

description: Using radio observations with the Green Bank Telescope, evidence has now been found for a second five-membered ring in the dense cloud Taurus Molecular Cloud-1 (TMC-1). Based on additional observations of an ongoing, large-scale, high-sensitivity spectral line survey (GOTHAM) at centimeter wavelengths toward this source, we have used a combination of spectral stacking, Markov chain Monte Carlo (MCMC), and matched filtering techniques to detect 2-cyanocyclopentadiene, a low-lying isomer of 1-cyanocyclopentadiene, which was recently discovered there by the same methods. The new observational data also yields a considerably improved detection significance for the more stable isomer and evidence for several individual transitions between 23 - 32 GHz. Through our MCMC analysis, we derive total column densities of $8.3\times10^{11}$ and $1.9\times10^{11}$ cm$^{-2}$ for 1- and 2-cyanocyclopentadiene respectively, corresponding to a ratio of 4.4(6) favoring the former. The derived abundance ratios point towards a common formation pathway - most likely being cyanation of cyclopentadiene by analogy to benzonitrile.

description: Psychology has had difficulty accounting for the creative, context-sensitive manner in which concepts are used. We believe this stems from the view of concepts as identifiers rather than bridges between mind and world that participate in the generation of meaning. This paper summarizes the history and current status of concepts research, and provides a non-technical summary of work toward an ecological approach to concepts. We outline the rationale for applying generalizations of formalisms originally developed for use in quantum mechanics to the modeling of concepts, showing how it is because of the role of context that deep structural similarities exist between the two. A concept is defined not just in terms of exemplary states and their features or properties, but also by the relational structures of these properties, and their susceptibility to change under different contexts. The approach implies a view of mind in which the union of perception and environment drives conceptualization, forging a web of conceptual relations or 'ecology of mind'.
Are Chinese courts determining the injunction applications of standard-essential patent owners according to law?

Publisher: name: Monash University

Subjects: subject: Law
subject: FOS: Law

description: This thesis argues that, in the absence in Chinese law of a comprehensive regime regulating the injunction determinations involving standard-essential patents, Chinese courts are applying principles and doctrines from China's basic law in these assessments. Such an approach is consistent with the established law in South Korea, Japan and other civil law jurisdictions, but imposes broader and more pervasive good faith conduct obligations on SEP owners than they would be familiar with from the licensing negotiation practices in common law jurisdictions.

description: Spin dynamics of two-dimensional electron gas confined in an asymmetrical quantum well is studied theoretically in the regime where the scattering frequency is comparable with the spin precession frequency due to the conduction band spin splitting. The spin polarization is shown to demonstrate quantum beats. If the spin splitting is determined by both bulk and structural asymmetry mechanisms the beats are damped at zero temperature even in the absence of a scattering. We calculate the decay of spin beats due to the thermal broadening of the electron distribution function and electron scattering. The magnetic field applied along the structure growth axis is shown to increase the frequency of the beats and shift system towards the collision dominated regime.

Is the cosmological constant an eigenvalue?

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We propose to reinterpret Einstein's field equations as a nonlinear eigenvalue problem, where the cosmological constant $Λ$ plays the role of the (smallest) eigenvalue. This interpretation is fully worked out for a simple model of scalar gravity. The essential ingredient for the feasibility of this approach is that the classical field equations be nonlinear, i.e., that the gravitational field is itself a source of gravity. The cosmological consequences and implications of this approach are developed and discussed.

description: We report the synthesis, (micro)structural, magneto-transport and magnetization of polycrystalline La2/3Ca1/3MnO3:Agx composites with x = 0.0, 0.1, 0.2, 0.3 and 0.4. The temperature coefficient of resistance (TCR) near ferromagnetic (FM) transition is increased significantly with addition of Ag. The FM transition temperature (TFM) is also increased slightly with Ag addition. Magneto-transport measurements revealed that magneto-resistance MR is found to be maximum near TFM. Further the increased MR of up to 60% is seen above 300 K for higher silver added samples in an applied field of 7 Tesla. Sharp TCR is seen near TFM with highest value of up to 15 % for Ag (0.4) sample, which is an order of magnitude higher than as for present pristine sample and best value yet reported for any polycrystalline LCMO compound. Increased TCR, TFM and significant above room temperature MR of La2/3Ca1/3MnO3:Agx composites is explained on the basis of improved grains size and connectivity with silver addition in the matrix. Better coupled FM domains and nearly conducting grain boundaries give rise to improved physical properties of the La2/3Ca1/3MnO3 manganites.

description: Αντικείμενο της παρούσας εργασίας είναι η υποστήριξη και η αξιολόγηση του μαθήματος «Εισαγωγή στη Άλγεβρα» του τμήματος Μαθηματικών του ΑΠΘ και συγκεκριμένα της δραστηριότητας που πραγματώνεται σε αυτή την εργασία. Αυτή είναι η καταγραφή σε βίντεο των διαλέξεων του μαθήματος, η επεξεργασία τους κατάλληλά και η διάθεσή τους στους φοιτητές μέσου διαδικτύου. Κατά την εξέλιξη αυτής της εργασίας μοιράσθηκαν δύο ερωτηματολόγια στους φοιτητές για να γίνει μια αξιολόγηση της στάσης τους απέναντι στο μάθημα έπειτα από την εισαγωγή αυτής της δραστηριότητας. Εν τέλει φάνηκε πως μεταβλήθηκε η στάση τους με θετικό τρόπο ως προς το μάθημα και επιπλέον είδαν με θετικό τρόπο τις βιντεοδιαλέξεις. Τέλος από τις απαντήσεις βγήκε το συμπέρασμα πως κάποιοι φοιτητές που δεν είχαν την δυνατότητα να παρακολουθήσουν το μάθημα στο αμφιθέατρο χρησιμοποίησαν την δυνατότητα που τους δόθηκε και παρακολούθησαν το μάθημα από τον υπολογιστή τους.
description: The objective of the present thesis is to support and evaluate the course "Introduction to Algebra" of the Department of Mathematics of Aristotle University of Thessaloniki and especially the activity that is discussed in this study. This activity is the video recording of the lectures, the editing of the videos and the sharing over the Internet to the students. During the progress of this thesis two questionnaires were distributed to the students to evaluate their attitude about the course after the introduction of this activity. Eventually it seemed that their attitude changed in a positive way to the course and furthermore they evaluated in a positive way video lectures. Finally it was concluded that some students who had not the chance to attend the course in the class used the opportunity given to them and watched the lesson from their computer.

description: The Schrodinger wave functional for the d=3+1 SU(N) vacuum is a partition function constructed in d=4; the exponent 2S in the square of the wave functional plays the role of a d=3 Euclidean action. We start from a gauge-invariant conjecture for the infrared-dominant part of S, based on dynamical generation of a gluon mass M in d=4. We argue that the exact leading term, of O(M), in an expansion of S in inverse powers of M is a d=3 gauge-invariant mass term (gauged non-linear sigma model); the next leading term, of O(1/M), is a conventional Yang-Mills action. The d=3 action that is the sum of these two terms has center vortices as classical solutions. The d=3 gluon mass, which we constrain to be the same as M, and d=3 coupling are related through the conjecture to the d=4 coupling strength, but at the same time the dimensionless ratio in d=3 of mass to coupling squared can be estimated from d=3 dynamics. This allows us to estimate the QCD coupling $α_s(M^2)$ in terms of this strictly d=3 ratio; we find a value of about 0.4, in good agreement with an earlier theoretical value but a little low compared to QCD phenomenology. The wave functional for d=2+1 QCD has an exponent that is a d=2 infrared-effective action having both the gauge-invariant mass term and the field strength squared term, and so differs from the conventional QCD action in two dimensions, which has no mass term. This conventional d=2 QCD would lead in d=3 to confinement of all color-group representations. But with the mass term (again leading to center vortices), N-ality = 0 mod N representations are not confined.
