A new view on relativity: Part 2. Relativistic dynamics

description: The Lorentz transformations are represented on the ball of relativistically admissible velocities by Einstein velocity addition and rotations. This representation is by projective maps. The relativistic dynamic equation can be derived by introducing a new principle which is analogous to the Einstein's Equivalence Principle, but can be applied for any force. By this principle, the relativistic dynamic equation is defined by an element of the Lie algebra of the above representation. If we introduce a new dynamic variable, called symmetric velocity, the above representation becomes a representation by conformal, instead of projective maps. In this variable, the relativistic dynamic equation for systems with an invariant plane, becomes a non-linear analytic equation in one complex variable. We obtain explicit solutions for the motion of a charge in uniform, mutually perpendicular electric and magnetic fields. By the above principle, we show that the relativistic dynamic equation for the four-velocity leads to an analog of the electromagnetic tensor. This indicates that force in special relativity is described by a differential two-form.

description: Topology and geometry of a sphere create constraints for particles that lie on its surface which they otherwise do not experience in Euclidean space. Notably, the number of particles and the size of the system can be varied separately, requiring a careful treatment of systems with one or several characteristic length scales. All this can make it difficult to precisely determine whether a particular system is in a disordered, fluid-like, or crystal-like state. Here, we show how order transitions in systems of particles interacting on the surface of a sphere can be detected by changes in two hyperuniformity parameters, derived from spherical structure factor and cap number variance. We demonstrate their use on two different systems -- solutions of the thermal Thomson problem and particles interacting via an ultra-soft potential of the generalized exponential model of order 4 -- each with a distinct parameter regulating their degree of ordering. The hyperuniformity parameters are not only able to detect the order transitions in both systems, but also point out the clear differences in the ordered distributions in each due to the nature of the interaction leading to them. Our study shows that hyperuniformity analysis of particle distributions on the sphere provides a powerful insight into fluid- and crystal-like order on the sphere.

Κατ’ αρχάς, παρατίθεται η διαχρονική εξέλιξη του ελληνικού νομοθετικού πλαισίου για τις εξαρτησιογόνες – ναρκωτικές ουσίες, αλλά και τα μοντέλα άσκησης αντεγκληματικής πολιτικής για την καταπολέμηση της διάδοσης των ναρκωτικών σε εθνικό και ευρωπαϊκό επίπεδο. Παραπέρα, εξετάζεται η αποτελεσματικότητα της ποινικοποίησης της χρήσης ναρκωτικών ουσιών στην Ελλάδα σε επίπεδο γενικής και ειδικής πρόληψης ενόψει και του προφίλ του εξαρτημένου δράστη. Τέλος, γίνεται ανάλυση του πατερναλιστικού προτύπου που υιοθετεί η πολιτεία για την καταπολέμηση του προβλήματος των ναρκωτικών και ελέγχεται η νομιμοποίηση αυτού. Εντός του ανωτέρω πλαισίου, εξάλλου, επιχειρείται και μία συνολική επισκόπηση του ν. 4139/2013 με τη σταχυολόγηση των θετικών και αρνητικών του σημείων
description: The purpose of this diploma thesis is to study the legal compatibility and criminality effectiveness of criminal law instrumentation in order to address the problem of the use of addictive substances. First of all, it presents the diachronic legislative framework for drug addicts, as well as the existent drug offending policies on a national and European basis. Furthermore, the effectiveness of the criminalization and decriminalization of drug use in Greece at the level of general and specific prevention is being examined, in view of the profile of the drug-addicted offender. Finally, the paternalistic model adopted by the state to confront the drug problem and its legalization are also analyzed. Within this framework, an overall review of Law 4139/2013 is also attempted by highlighting its positive and negative points.

We find a novel interplay between ferromagnetism and superconductivity, manifested in the Josephson effect. This offers the possibility of tuning dissipationless currents of charge and spin in a well-defined manner by adjusting the magnetization direction on either side of the junction.

description: Store atmosphere includes the physical characteristics of a retail store that are used to create an image which attracts potential and existing customers. Store atmosphere is a direct contributor to customer experience and customer satisfaction, which are considered to be the most important elements of the retail business today. The focus of this research study is the effect of store atmosphere or also known as atmospherics for short, on customer satisfaction. For the purpose of this thesis, a broad review and analysis was done on previous literature about store atmosphere and its sub-dimensions and customer satisfaction, as well as on the relationship between these two constructs. Furthermore, an empirical research was conducted, consisting of a questionnaire and respondents were customers of the super market AB Vasilopoulos (in Finikas, Kalamaria). Moreover, the responses of the questionnaire were analyzed and several analyses were done: reliability analysis, correlation analysis and ANOVA analysis. These statistical analyses contribute to the final outcome of this research study which was the conclusion that the store atmosphere has positive and significant effect on customer satisfaction
Adrenergic modulation of glutamate induced calcium mobilization in cultured rat visual cortical neurons
Creators: name: Yang, Benduan
Publisher: name: University of British Columbia
Year: 2009

description: Since Wiesel and Hubel first discovered that the responsiveness of the cortical neurons in the striate cortex to visual stimuli via either eye was subject to postnatal developmental manipulation, three decades have passed in strenuous efforts to unravel the mechanism underlying this ocular dominance plasticity. Among these studies, a variety of neurotransmitters/neuromodulators, including noradrenalin, acetylcholine and serotonin, have been implicated at both system and cellular levels. In view of the facts that noradrenalin changes neuronal excitability and the N-Methyl-D-aspartate (NMDA) receptor plays a crucial role in neuroplasticity, this study was designed to obtain evidence whether adrenergic modification worked through interacting with glutamergic system in terms of calcium dynamics and how this process occurred. In primary neuronal cultures derived from the visual cortex of embryonic day 16-18 rats, intracellular free calcium concentration, [Ca²⁺]i, was increased by bath application of glutamate in a dose dependent manner. Noradrenalin applied alone had relatively small effects. However, when glutamate concentrations eliciting modest increases in [Ca²⁺]i were applied together with 1 µM noradrenalin, the increase in [Ca²⁺]i could be enhanced by a factor of up to eight in 147 neurons out of a total of 215 cells observed in 54 experiments. The observed enhancement was much more obvious at low doses of glutamate than with higher doses, augmenting all submaximal calcium responses to similar asymptotic levels. 2-Amino-5-phosphonovalerate (APV), the NMDA receptor antagonist, completely blocked the adrenergic enhancing effect (29/29 cells in 8 experiments). Among the antagonists specific to άl , ά2 and ϐ subtypes of adrenoceptors, the ϐ antagonist propranolol most completely blocked the enhancing effect (13/14 cells in 4 experiments, by an amplitude of 90%). The involvement of the ϐ receptor pathway was further supported by the ability of a cAMP analog to mimic the enhancing effect of noradrenalin. These results suggest that receptors for noradrenalin and glutamate colocalize on postsynaptic cortical cells and that adrenergic modulation of glutamate induced calcium influx most likely work through the ϐ receptor pathway. It is further postulated that ocular dominance plasticity may be at least partially implemented via a calcium dependent cascade.

description: The Hamiltonian of the magic-angle twisted symmetric trilayer graphene (TSTG) can be decomposed into a TBG-like flat band Hamiltonian and a high-velocity Dirac fermion Hamiltonian. We use Hartree-Fock mean field approach to study the projected Coulomb interacting Hamiltonian of TSTG developed in Călugăru et al. [Phys. Rev. B 103, 195411 (2021)] at integer fillings $ν=-3, -2, -1$ and $0$ measured from charge neutrality. We study the phase diagram with $w_0/w_1$, the ratio of $AA$ and $AB$ interlayer hoppings, and the displacement field, which introduces an interlayer potential $U$ and hybridizes the TBG-like bands with the Dirac bands. At small $U$, we find the ground states at all fillings $ν$ are in the same phases as the tensor products of a Dirac semimetal with the filling $ν$ TBG insulator ground states, which are spin-valley polarized at $ν=-3$, and fully (partially) intervalley coherent at $ν=-2,0$ ($ν=-1$) in the flat bands. An exception is $ν=-3$ with $w_0/w_1 \gtrsim 0.7$, which possibly become a metal with competing orders at small $U$ due to charge transfers between the Dirac and flat bands. At strong $U$ where the bandwidths exceed interactions, all the fillings $ν$ enter a metal phase with small or zero valley polarization and intervalley coherence. Lastly, at intermediate $U$, semimetal or insulator phases with zero intervalley coherence may arise for $ν=-2,-1,0$. Our results provide a simple picture for the electron interactions in TSTG systems, and reveal the connection between the TSTG and TBG ground states.

Nievo, Ippolito 304/1831-4/3/1861

description: Ο Ippolito Nievo μπορεί να θεωρηθεί ως μια από τις σημαντικότερες μορφές στην ιστορία της Ιταλικής Λογοτεχνίας. Το έργο του συνδέεται – λαμβάνοντας υπόψη τα θέματά του – με το ιστορικό φαινόμενο του Ιταλικού Risorgimento, δηλαδή τον αγώνα των ανθρώπων της Ιταλίας για την ανεξαρτησία και την ενοποίηση της χώρας τους. Η ζωή του Nievo είχε υπάρξει ένας συνδυασμός έντονης πατριωτικής δράσης και έκφρασης των διαφόρων ιδεών του μέσα από τα έργα και τα γραπτά του. Ο Nievo είχε συμμετάσχει σε πολλά επαναστατικά κινήματα κατά των αυστριακών αρχών κατά μήκος της ιταλικής χερσονήσου στη διάρκεια των δυο πρώτων Πολέμων του Ιταλικού Risorgimento. Ακόμα συμμετείχε στην επιχείρηση των Χιλίων του Γκαριμπάλντι στη Σικελία. Πέθανε λίγο αργότερα, ενώ επέστρεφε από τη Σικελία, όταν το ατμόπλοιο που μετέφερε αυτόν και άλλους Ιταλούς πατριώτες στρατιώτες, βυθίστηκε στο Τυρρηνικό Πέλαγος. Μια σημαντική πτυχή του έργου του, όπως δείχνει η παρούσα διπλωματική, ήταν το ότι είχε εμπνευστεί σε μεγάλο βαθμό από το παράδειγμα του Ελληνικού Αγώνα της Ανεξαρτησίας. Η Ελλάδα είχε υπάρξει για τον Nievo ένα παράδειγμα ελευθερίας και αγώνα κατά της τυραννίας. Η αρχαία Ελλάδα επίσης φαίνεται να παίζει έναν σημαντικό ρόλο στο έργο του. Αυτό είναι εμφανές στο έργο του Εξομολογήσεις ενός Ιταλού που είναι το κύριο θέμα αυτής της διπλωματικής
description: Ippolito Nievo can be considered as one of the most important figures in the history of the Italian Literature. His work is connected - considering its themes - to the historic phenomena of the Italian Risorgimento, the struggle of the people of Italy for the liberation and the unification of their country. Nievo's life had been a combination of intense patriotic action and of expressing his various ideas thorugh his works and writings. Nievo had participated in many revolutionary movements against the Austrian authorities across the italian peninsula during the period of the first two Wars for the Italian Risorgimento. He also participated at Garibaldi's Operation of the Thousand in Sicily. He died a little bit later, while returning from Sicily, when the steamship carrying him and other Italian patriot soldiers, sunk at the Tyrrinian Sea. One major aspect of his work as the current dissertation shows, was that he had been higlhy inspired by the example of the Greek War of Independence. Greece had been for Nievo an example of freedom and of fighting against tyranny. Ancient Greece also seems playing a special role in his work. This is obvious in his work Confessions of an Italian which is the main subject of this dissertation

description: This paper is a theoretical work in support of a newly proposed experiment (R. Stutz and E. Cornell, Bull. Am. Soc. Phys. 89, 76 2004) that promises greater sensitivity to measurements of the electron's electric dipole moment (EDM) based on the trapping of molecular ions. Such an experiment requires the choice of a suitable molecule that is both experimentally feasible and possesses an expectation of a reasonable EDM signal. We find that the molecular ions PtH+, HfH+, and HfF+ are suitable candidates in their low-lying triplet Delta states. In particular, we anticipate that the effective electric fields generated inside these molecules are approximately of 73 GV/cm, -17 GV/cm, and -18 GV/cm respectively. As a byproduct of this discussion, we also explain how to make estimates of the size of the effective electric field acting in a molecule, using commercially available, nonrelativistic molecular structure software.

description: The high luminosity that will be accumulated at the LHC will enable precise differential measurements of the hadronic production of a top--antitop-quark pair in association with a $\text{W}$ boson. Therefore, an accurate description of this process is needed for realistic final states. In this work we combine for the first time the NLO QCD and electroweak corrections to the full off-shell $\text{t}\overline{\text{t}}{\text{W}}^+$ production at the LHC in the three-charged-lepton channel, including all spin correlations, non-resonant effects, and interferences. To this end, we have computed the NLO electroweak radiative corrections to the leading QCD order as well as the NLO QCD corrections to both the QCD and the electroweak leading orders.

description: Initiation of the pilot Federal Food Stamp Program at home and the Food for Peace Program abroad has focused national attention upon public programs to utilize part of agriculture's abundant resources in improving the health and well-being of children and needy persons. These include the domestic National School Lunch, Special Milk, Direct Distribution, and Food Stamp Programs and the international People-to-People food assistance programs. During fiscal year 1961, more than 30 million persons in the United States and its territories and 60 million persons abroad received benefits through these public programs. During this period, Federal contributions through these programs were valued at almost $700 million. Each of these public food distribution programs is designed to accomplish dual objectives: Expand demand for the abundant flow of foods from the nation's farms and conserve human resources through better nutrition. Well known are the nutritional benefits attained through each program. Less understood is the agricultural mission and how it is accomplished.

description: Background: Endometriosis is one of the most common gynecological diseases of reproductive age, with a prevalence of 5 - 10% and grave consequences in quality of life and fertility. Vitamin D (vit D), a classic regulator of plasma calcium concentration and skeleton mineralization, is also an effective modulator of the immune system. Several studies suggest that immunologic properties attributed to vit D along with vit D receptor (VDR) expression in reproductive tissues may be involved in the pathogenesis of endometriosis. Objective: To systematically review the literature for the association between products which are involved in vit D metabolism and endometriosis. Materials and Methods: A systematic review of the published literature in Medline and Cochrane Central was conducted for original research articles on humans, published in any language. Results: Seventeen studies were included in the systematic review. Among them, eight examined the relationship of endometriosis with vit D metabolites, six with vit D binding protein (VDBP), three with VDR polymorphisms and two with vit D regulatory enzymes. Conclusions: This is the first systematic attempt to collect, evaluate and present the known data on this topic. Given the heterogeneity and the diversity of the present studies, more studies are needed in order to extract safer conclusions.

description: In the temperature (T)-nuQ3 phase diagram of NaxCoO2 \dot yH2O, there exist two superconducting regions of nuQ3 separated by the nonsuperconducting region, where nuQ3 is usually estimated from the peak position of the 59Co-NQR spectra of the 5/2-7/2 transition and well-approximated here as nuQ3~3nuQ,nuQ being the interaction energy between the nuclear quadrupole moment and the electric field gradient. We have carried out measurements of the 59Co-NMR Knight shift (K) for a single crystal in the higher-nuQ3 superconducting phase and found that K begins to decrease with decreasing T at Tc for both magnetic field directions parallel and perpendicular to CoO2-planes. The result indicates together with the previous ones that the superconducting pairs are in the spin-singlet state in both phases, excluding the possibility of the spin-triplet superconductivity in this phase diagram. The superconductivity of this system spreads over the wide nuQ3 regions, but is suppressed in the narrow region located at the middle point of the region possibly due to charge instability.

X-ray Spectral Variability of TeV Blazars during Rapid Flares

description: The spectral energy distribution (SED) of TeV blazars peaks both at keV and TeV energies. The X-ray emission is generally believed to originate in the synchrotron emission from relativistic electrons (and positrons) in the jet of these sources, while the origin of the gamma-ray emission is still being debated. We report results from a systematic study of X-ray spectral variability of Mrk 421 and Mrk 501 during individual flares that last for several days, making use of some of the high-quality data that have recently become available. The X-ray spectra of the two sources fall on the opposite sides of the synchrotron peak of their respective SEDs, so they together may offer additional insights into the physical origin of X-ray variability. We modeled each of the time-resolved X-ray spectra over a {\em single} flare by adopting a homogeneous spatial distribution and an instantaneous power-law spectral distribution for the emitting particles. We focused on the variation of four key parameters: particle spectral index, maximum Lorentz factor, energy density, and magnetic field. While there is considerable degeneracy in the fits, we show that, in order to account for the X-ray spectral variability observed in Mrk 421, at least three of the parameters are required to vary in most cases, with the spectral index being one of them. The observations of Mrk 501 support the conclusion, although the quality of the data is not as good. We discuss the implications of the results.

description: We simulate the bulge formation in very late-type dwarf galaxies from circumnuclear super star clusters (SSCs) moving in a responding cuspy dark matter halo (DMH). The simulations show that (1) the response of DMH to sinking of SSCs is detectable only in the region interior to about 200 pc. The mean logarithmic slope of the responding DM density profile over that area displays two different phases: the very early descent followed by ascent till approaching to 1.2 at the age of 2 Gyrs. (2) the detectable feedbacks of the DMH response on the bulge formation turned out to be very small, in the sense that the formed bulges and their paired nuclear cusps in the fixed and the responding DMH are basically the same, both are consistent with $HST$ observations. (3) the yielded mass correlation of bulges to their nuclear (stellar) cusps and the time evolution of cusps' mass are accordance with recent findings on relevant relations. In combination with the consistent effective radii of nuclear cusps with observed quantities of nuclear clusters, we believe that the bulge formation scenario that we proposed could be a very promising mechanism to form nuclear clusters.

description: Temperature- and field-dependent measurements of the Hall effect of pure and 4 % Rh-doped URu$_{2}$Si$_{2}$ reveal low density (0.03 hole/U) high mobility carriers to be unique to the `hidden order' phase and consistent with an itinerant density-wave order parameter. The Fermi surface undergoes a series of abrupt changes as the magnetic field is increased. When combined with existing de Haas-van Alphen data, the Hall data expose a strong interplay between the stability of the `hidden order,' the degree of polarization of the Fermi liquid and the Fermi surface topology.

description: Questo articolo illustra alcuni risultati di una ricerca condotta sugli atteggiamenti degli insegnanti di classi plurilingue nei confronti dei propri alunni di origine immigrata di prima e/o seconda generazione o neoarrivati. A partire da due esperienze di focus group e attraverso un modello multidimensionale degli atteggiamenti, è stato elaborato un questionario per la cui compilazione sono state coinvolte ventisette scuole primarie del Piemonte. I dati che verranno presentati si riferiscono innanzitutto agli elementi di conoscenza rispetto alle lingue parlate a casa dagli alunni; permettono poi di comprendere come possano essere valutate le diverse implicazioni del plurilinguismo nei processi di apprendimento; infine offrono una panoramica di esperienze didattiche attraverso le quali si concretizza l’intento di valorizzare le varie “lingue di casa”.
L’esplorazione degli atteggiamenti degli insegnanti rappresenta un punto di partenza essenziale per comprendere le modalità con le quali promuovere l’educazione plurilingue, obiettivo irrinunciabile per la nostra scuola e per la nostra società.

Plurilingual Education and teachers’ attitudes

This article discusses some of the research results on the attitudes of teachers towards the fact that some of their students have a multilingual repertoire.
Based on two focus groups and a multi-dimensional model of the attitudes, a questionnaire was developed and administered in twenty-seven primary schools in the Piedmont region of Italy. The data presented relates primarily to knowledge with respect to languages spoken at home by students; we then consider how the different implications of multilingualism in learning processes can be evaluated; finally, there is an overview of educational experiences which intend to give value to the various “languages from home”.
The exploration of teachers’ attitudes is an essential starting point for understanding how to promote multilingual education, an essential goal for our schools and for our society.

description: Six binary-merger progenitors of Supernova 1987A (SN 1987A) with properties close to those of the blue supergiant Sanduleak -69 202 are exploded by neutrino heating and evolved until long after shock breakout in three dimensions (3D), and continued for light-curve calculations in spherical symmetry. Our results confirm previous findings for single-star progenitors: (1) 3D neutrino-driven explosions with SN 1987A-like energies synthesize Ni-56 masses consistent with the radioactive light-curve tail; (2) hydrodynamic models mix hydrogen inward to minimum velocities below 40 km/s compatible with spectral observations of SN 1987A; and (3) for given explosion energy the efficiency of outward radioactive Ni-56 mixing depends mainly on high growth factors of Rayleigh-Taylor instabilities at the (C+O)/He and He/H composition interfaces and a weak interaction of fast plumes with the reverse shock occurring below the He/H interface. All binary-merger models possess presupernova radii matching the photometric radius of Sanduleak -69 202 and a structure of the outer layers allowing them to reproduce the observed initial luminosity peak in the first about 7 days. Models that mix about 0.5 Msun of hydrogen into the He-shell and exhibit strong outward mixing of Ni-56 with maximum velocities exceeding the 3000 km/s observed for the bulk of ejected Ni-56 have light-curve shapes in good agreement with the dome of the SN 1987A light curve. A comparative analysis of the best representatives of our 3D neutrino-driven explosion models of SN 1987A based on single-star and binary-merger progenitors reveals that only one binary model fulfills all observational constraints, except one.

description: We present a Coherent X-ray Diffraction study of the antiferrodistortive displacive transition of SrTiO$_3$, a prototypical example of a phase transition for which the critical fluctuations exhibit two length scales and two time scales. From the microbeam x-ray coherent diffraction patterns, we show that the broad (short-length scale) and the narrow (long-length scale) components can be spatially disentangled, due to 100 $μ$m-scale spatial variations of the latter. Moreover, both components exhibit a speckle pattern, which is static on a $\sim$10 mn time-scale. This gives evidence that the narrow component corresponds to static ordered domains. We interpret the speckles in the broad component as due to a very slow dynamical process, corresponding to the well-known \emph{central} peak seen in inelastic neutron scattering.

Quantitation of human megakaryocyte progenitor cells in semi-solid cultures
Creators: name: Fanning, Stephen Francis
Publisher: name: University of British Columbia
Year: 2009

description: In vitro assays for the study of human megakaryocyte (Mk) progenitor cells have been compromised by the exquisite sensitivity of these cells to transforming growth factor-ϐ (TGF-ϐ) (which is found in : inhibitory concentrations in serum and plasma) and a need to use immunocytochemical methodology to specifically identify clonal populations of Mk lineage cells. The present studies were undertaken to identify conditions that would overcome both of these problems and allow human Mk progenitors to be detected at optimal efficiency. The final procedure developed involved plating normal adult human bone marrow cells in chamber-slides in cell culture grade agarose dissolved in Iscove's medium supplemented with 1% albumin, 200 µg/ml iron-saturated transferrin, 10 µg/ml insulin, 40 mmol/L l ow density lipoproteins, 5 x 10⁻⁵M 2-mercaptoethanol and a growth factor cocktail consisting of IL-3, IL-6, GM-CSF and Steel factor. After 2 to 3 weeks at 37°C , cultures were fixed in methanol: acetone and colonies containing cells expressing glycoprotein IIb/IIIa identified by immunoperoxidase staining. Colonies containing increasing numbers of positively stained cells appeared after increasing periods of time consistent with the presence in normal human bone marrow of a hierarchy of Mk progenitor cells of differing proliferative potential. These conditions were found to be superior to serum- or plasmacontaining medium in their ability to support the proliferation of human Mk progenitor cells. Dose response studies were undertaken to confirm that the concentrations of albumin and 2-mercaptoethanol were optimal. For 2 of 3 bone marrows, the number of Mk colonies seen. with up to 80 mmol/L low density lipoproteins was the same as when these were not added to the medium. The growth factor combination of insulin, IL-3, IL-6, G M - C S F and Steel factor was superior to other combinations tested (including some containing G-CSF and/or IL-11) and provided maximal stimulation of the larger (>50 cells/colony) Mk colonies. Under these conditions, the Mk colony yield after 18 to 20 days was linearly related to the number of cells plated over a wide range of cell concentrations. These findings validate the use of this assay for future studies of the factors regulating both the development and subsequent differentiation of human Mk progenitor cells.

description: Η παρούσα διπλωματική εργασία πραγματεύεται αν η αντιμετώπιση της κατοχής ναρκωτικών ουσιών ως αξιόποινης πράξης, από τον Έλληνα νομοθέτη, είναι επαρκής, και επομένως, αν πρέπει να τροποποιηθεί ή όχι η ισχύουσα νομοθεσία, για να αντιμετωπιστεί πιο αποτελεσματικά το ζήτημα του αξιοποίνου. Έλαβε χώρα κριτική ανάλυση της νομοθεσίας που ισχύει για την κατοχή ναρκωτικών ουσιών. Από τη διερεύνηση αυτή θα μπορέσει κανείς να συμπεράνει αν δικαιολογείται, πότε και μέχρι ποιο βαθμό η επιβολή ποινικών κυρώσεων και στη συνέχεια, να υποδείξει ποια άλλα μέτρα είναι ακόμα ανάγκη να ληφθούν.
description: This dissertation deals with whether the treatment of drug possession as a criminal offense by the Greek legislator is sufficient enough and thus whether or not the existing legislation needs to be amended to address the issue of criminality more effectively. A critical analysis of the legislation on drug possession has taken place. From this research, it can be inferred, when and to what extent the imposition of criminal sanctions is justified and then it can be indicated what other measures still have to be taken.

description: Σκοπός της εργασίας ήταν η παρουσίαση του φαινομένου της κινητικότητας των εμπορικών εταιριών από το κράτος μέλος της έδρας τους εντός της Ευρωπαϊκής Ένωσης. Αρχικά, έγινε αναφορά στις σημαντικότερες θεωρίες για την ιθαγένεια μίας εταιρίας αλλά και σε αυτή που επικρατεί στην ελληνική έννομη τάξη. Στη συνέχεια, παρατέθηκαν αναλυτικά οι θέσεις του Ευρωπαϊκού Δικαστηρίου αναφορικά με το δικαίωμα εγκατάστασης των εταιριών αλλά και ως προς τις διασυνοριακές συγχωνεύσεις και την επίδρασή τους στην κινητικότητα των εταιριών. Τέλος, εξετάστηκε η Ευρωπαϊκή Εταιρία και η σημασία θέσπισης της 14ης Εταιρικής Οδηγίας
description: The aim of this thesis was to present the phenomenon of the cross-border mobility of companies by their Member State of residence within the European Union. Firstly reference was made to the most important theories about the nationality of a company and also to that prevailing in the Greek legal order. Then were introduced analytically the positions of European Court regarding the freedom of establishment of companies and also the cross-border mergers and their impact to the corporate mobility. In the end is examined the European Company and the importance of adopting the 14th Company Law Directive

description: This research aims to observe and describe how a community adapts its governance system to a changing socioecological context, particularly implying the transformation of economical conceptions as well as linkages between culture and territory. We study this under the approach of Territories and Areas Conserved by Indigenous Peoples and Local Communities (Borrini-Feyerabend et al., 2014), considering that pastoralist communities (among other ecosystem-based economies and cultures) have governed, managed, and conserved territories through constant readaptation over time and in front of multiple pressures and drivers of global change (Kothari et al., 2012). The case study is located in the mountain region of the Sierra de Segura (Fig.1a and 1b), being pastoralism a traditional and well adapted lifestyle to particular climatic and geographic conditions (cold winter, hot dry-summer, dry limestone soils, etc.).

description: We present a single-exposure fabrication technique for a very large array of microscopic air-bridges using a tri-layer resist process with electron-beam lithography. The technique is capable of forming air-bridges with strong metal-metal or metal-substrate connections. This was demonstrated by its application in an electron tunnelling device consisting of 400 identical surface gates for defining quantum wires, where the air-bridges are used as suspended connections for the surface gates. This technique enables us to create a large array of uniform one-dimensional channels that are open at both ends. In this article, we outline the details of the fabrication process, together with a study and the solution of the challenges present in the development of the technique, which includes the use of water-IPA (isopropyl alcohol) developer, calibration of resist thickness and numerical simulation of the development.

description: In this paper we revisit the Adler-Bobenko-Suris H2 equation. The H2 equation is linearly related to the $S^{(0,0)}$ and $S^{(1,0)}$ variables in the Cauchy matrix scheme. We elaborate the coupled quad-system of $S^{(0,0)}$ and $S^{(1,0)}$ in terms of their 3-dimensional consistency, Lax pair, bilinear form and continuum limits. It is shown that $S^{(1,0)}$ itself satisfies a 9-point lattice equation and in continuum limit $S^{(1,0)}$ is related to the eigenfunction in the Lax pair of the Korteweg-de Vries equation.
