description: Quenching and annealing are extreme opposites in the time evolution of a quantum system: Annealing explores equilibrium phases of a Hamiltonian with slowly changing parameters and can be exploited as a tool for solving complex optimization problems. In contrast, quenches are sudden changes of the Hamiltonian, producing a non-equilibrium situation. Here, we investigate the relation between the two cases. Specifically, we show that the minimum of the annealing gap, which is an important bottleneck of quantum annealing algorithms, can be revealed from a dynamical quench parameter which describes the dynamical quantum state after the quench. Combined with statistical tools including the training of a neural network, the relation between quench and annealing dynamics can be exploited to reproduce the full functional behavior of the annealing gap from the quench data. We show that the partial or full knowledge about the annealing gap which can be gained in this way can be used to design optimized quantum annealing protocols with a practical time-to-solution benefit. Our results are obtained from simulating random Ising Hamiltonians, representing hard-to-solve instances of the exact cover problem.

description: Η παρούσα μεταπτυχιακή εργασία είχε ως σκοπό να εξετάσει την αύξηση της ανθεκτικότητας των ωμοπλίνθων έναντι υγρασίας με την εφαρμογή επικαλύψεων/επιχρισμάτων που θα βασίζονταν στη χρήση παραδοσιακών υλικών, όπως είναι ο πηλός και ο ασβέστης. Οι επικαλύψεις αυτές τροποποιήθηκαν με χρήση νανοπυριτίας, μετακαολίνη, λινέλαιου, πυριτικού και καυστικού νατρίου. Οι δύο πρώτες συνθέσεις επικαλύψεων, προήλθαν από συνδυασμό των δύο ειδών πολτού ασβέστη και πηλού. Ενώ οι υπόλοιπες συνθέσεις προήλθαν από τα δύο αυτά είδη παραδοσιακών επιχρισμάτων και τα παραπάνω πρόσθετα. Κατόπιν έγιναν έλεγχοι στα δοκίμια για να διαπιστωθεί η επίδραση των επικαλύψεων στην αύξηση της αντοχής έναντι υγρασίας. Αυτοί οι έλεγχοι περιελάμβαναν: Δοκιμή τριχοειδούς απορρόφησης, έλεγχο σταγόνας, μικροσκοπική παρατήρηση επικαλύψεων, δοκιμή αντίστασης σε διάβρωση από νερό και δοκιμή νέφωσης. Από τη μελέτη των αποτελεσμάτων των παραπάνω ελέγχων προέκυψαν τα ακόλουθα αποτελέσματα: Τα δύο δοκίμια, στα οποία εφαρμόστηκαν οι παραδοσιακές επικαλύψεις (ασβέστης και πηλός) με προσθήκη λινελαίου, παρουσίασαν την καλύτερη συμπεριφορά έναντι υγρασίας σε σχέση με όλες τις υπόλοιπες συνθέσεις, ακολούθησε η προσθήκη νανοπυριτίου και στη συνέχεια πυριτικού και καυστικού νατρίου. Η προσθήκη μετακαολίνη και πυριτικού νατρίου στις παραδοσιακές συνθέσεις επιχρισμάτων δεν παρουσίασε βελτίωση της αντοχής τους έναντι υγρασίας, σε σχέση με τα παραδοσιακά επιχρίσματα χωρίς πρόσθετα.
description: In the present MSc thesis, the moisture resistance of traditional lime-clay coatings was studied. These coatings were modified by the addition of SiO2, metakaolin, lineleum, sodium silicate, and sodium hydrogen. Two of the compositions consisted of only lime putty and clay. The rest of the mixes were made by these two traditional coatings and the additives described above. The specimens were then subjected to tests in order to evaluate the influence in the water resistance of the addition of these materials in the traditional coating compositions. These tests were: water absorption test, drop absorption test, microscopic observation of the renders, water erosion test and fog test (vapor condensation test). After the completion of the tests, the following results were concluded: The two specimens with the traditional coatings and the addition of lineleum, presented the higher water resistance of all the specimens. Next was the addition of SiO2 and sodium silicate with sodium hydrogen. The addition of metakaolin and sodium silicate in the traditional coating compositions did not improve their moisture resistance, compared to the resistance of the traditional coatings without these additives.
BEHAVIORAL ECOLOGY OF JUVENILE PALILA (Loxioides bailleui): FORAGING DEVELOPMENT, SOCIAL DYNAMICS, AND HELPING BEHAVIOR

Year: 1998

description: The purpose of this study was to systematically document helping
development of foraging in juvenile Palila, an endangered Hawaiian
honeycreeper found only on Mauna Kea on the island of Hawaii. Though
incidental observations of helpers-at-the-nest have been made,
intensive nest monitoring revealed that 30 to 50% of nests had one
extra after-second-year male provisioning food to the nestling(s).
Helping at the fledgling stage was also confirmed. Radiotracking
revealed information regarding foraging development and movement
patterns of juveniles. Adult males provided one-on-one food
supplementation and foraging instruction to young for three to four
months after fledging. Particular benchmarks in the development of
foraging skills in juveniles were identified. Juvenile survival may
be a factor limiting the Palila population. This investigation
constitutes the first detailed study of a juvenile Hawaiian forest
bird, and thus, may serve as model for understanding the ecology of
other species.

Οι υπολογισμοί γίνονται σε ένα χρονικό παράθυρο που κινείται κατά μήκος του χρονικού διαστήματος. Τα μέτρα που μελετώνται είναι ο δείκτης αιτιότητας κατά Granger, ο δείκτης αιτιότητας κατά Granger υπό συνθήκη, ο συντελεστής διασυσχέτισης και ο συντελεστής μερικής διασυσχέτισης. Για την αξιολόγηση των μέτρων στην εύρεση των συνδέσεων θα χρησιμοποιήσουμε τις έννοιες της ευαισθησίας και της ειδικότητας, ενώ για τον εντοπισμό της αλλαγής χρησιμοποιούμε τις καμπύλες ROC. Για τη σύγκριση των μέτρων χρησιμοποιούνται μέτρα δικτύων: ο μέσος βαθμός, το μέσο μήκος μονοπατιού και ο συντελεστής συσταδοποίησης. Στο τέλος εφαρμόζουμε τη διαδικασία που αναπτύξαμε σε δεδομένα χρηματιστηριακών δεικτών.
description: The aim of this study is to evaluate time series connectivity measures to identify connections and structural changes in dynamic networks formed by time series. The calculations are made in a time window that moves along the interval. The selected measures are Granger causality index, conditional Granger causality index, cross-correlation and partial cross-correlation. In order to evaluate the ability of the measures in detecting correctly the connections we use the indices of sensitivity and specificity, and we use also the ROC curves in order to identify the time of the change. The network measures used to compare the connectivity measures are the average degree, the average shortest path and the clustering coefficient. At the end we apply the developed procedure to international stock-market data.
Coherence oscillations in dephasing by non-Gaussian shot noise

description: A non-perturbative treatment is developed for the dephasing produced by the shot noise of a one- dimensional electron channel. It is applied to two systems: a charge qubit and the electronic Mach-Zehnder interferometer, both of them interacting with an adjacent partitioned electronic channel acting as a detector. We find that the visibility (interference contrast) can display oscillations as a function of detector voltage and interaction time. This is a unique consequence of the non-Gaussian properties of the shot noise, and only occurs in the strong coupling regime, when the phase contributed by a single electron exceeds pi. The resulting formula reproduces the recent surprising experimental observations reported in [I. Neder et al., cond-mat/0610634], and indicates a general explanation for similar visibility oscillations observed earlier in the Mach-Zehnder interferometer at large bias voltage. We explore in detail the full pattern of oscillations as a function of coupling strength, voltage and time, which might be observable in future experiments.

description: We present a Monte Carlo based analysis of the combined world data on polarized lepton-nucleon deep-inelastic scattering at small Bjorken $x$ within the polarized quark dipole formalism. We show for the first time that double-spin asymmetries at $x<0.1$ can be successfully described using only small-$x$ evolution derived from first-principles QCD, allowing predictions to be made for the $g_1$ structure function at much smaller $x$. Anticipating future data from the Electron-Ion Collider, we assess the impact of electromagnetic and parity-violating polarization asymmetries on $g_1$ and demonstrate an extraction of the individual flavor helicity PDFs at small $x$.

description: The continuum-fitting and the iron line methods are currently the two leading techniques for probing the strong gravity region around accreting black holes. In the present work, we test the Kerr black hole hypothesis with the stellar-mass black hole in GRS 1915+105 by analyzing five disk-dominated RXTE spectra and one reflection-dominated Suzaku spectrum. The combination of the constraints from the continuum-fitting and the iron line methods has the potential to provide more stringent tests of the Kerr metric. Our constraint on the Johannsen deformation parameter $α_{13}$ is $-0.15 < α_{13} < 0.14$ at 3$σ$, where the Kerr metric is recovered when $α_{13} = 0$.

description: We present a comprehensive analysis of the potential sensitivity of the Electron-Ion Collider (EIC) to charged lepton flavor violation (CLFV) in the channel $ep\to τX$, within the model-independent framework of the Standard Model Effective Field Theory (SMEFT). We compute the relevant cross sections to leading order in QCD and electroweak corrections and perform simulations of signal and SM background events in various $τ$ decay channels, suggesting simple cuts to enhance the associated estimated efficiencies. To assess the discovery potential of the EIC in $τ$-$e$ transitions, we study the sensitivity of other probes of this physics across a broad range of energy scales, from $pp \to e τX$ at the Large Hadron Collider to decays of $B$ mesons and $τ$ leptons, such as $τ\to e γ$, $τ\to e \ell^+ \ell^-$, and crucially the hadronic modes $τ\to e Y$ with $Y \in \{ π, K, ππ, K π, ...\}$. We find that electroweak dipole and four-fermion semi-leptonic operators involving light quarks are already strongly constrained by $τ$ decays, while operators involving the $c$ and $b$ quarks present more promising discovery potential for the EIC. An analysis of three models of leptoquarks confirms the expectations based on the SMEFT results. We also identify future directions needed to maximize the reach of the EIC in CLFV searches: these include an optimization of the $τ$ tagger in hadronic channels, an exploration of background suppression through tagging $b$ and $c$ jets in the final state, and a global fit by turning on all SMEFT couplings, which will likely reveal new discovery windows for the EIC.

description: A novel observable measuring the $C\!P$ asymmetry in multi-body decays of heavy mesons, which is called the forward-backward asymmetry induced $C\!P$ asymmetry (FBI-$C\!P$A), $A_{CP}^{FB}$, is introduced. This observable has the dual advantages that 1) it can isolate the $C\!P$ asymmetry associated with the interference of the $S$- and $P$-wave amplitude from that associated with the $S$- or $P$-wave amplitude alone; 2) it can effectively almost double the statistics comparing to the conventionally defined regional $C\!P$ asymmetry. We also suggest to perform the measurements of FBI-$C\!P$A in some three-body decay channels of charm and beauty mesons.

description: We study the effect of disorder and doping on the metal-insulator transition in a repulsive Hubbard model on a square lattice using the determinant quantum Monte Carlo method. First, with the aim of making our results reliable, we compute the sign problem with various parameters such as temperature, disorder, on-site interactions, and lattice size. We show that in the presence of randomness in the hopping elements, the metal-insulator transition occurs and the critical disorder strength differs at different fillings. We also demonstrate that doping is a driving force behind the metal-insulator transition.

Who can speak for whom?: struggles over representation during the Charlottetown referendum campaign
Creators: name: Kernerman, Gerald P.
Publisher: name: University of British Columbia
Year: 2009

description: In this study, I undertake a discourse analysis of struggles over representation as they were manifested in the Charlottetown referendum campaign. I utilize transcripts taken during the campaign derived from the CBC news programs The National, The Journal, and Sunday Report as well as from The CTV News. The issue of (im-)partiality provides the analytical focus for this study. Who can legitimately speak on behalf of whom, or, to what extent do individuals have a particular voice which places limitations on whom they can represent? On the one hand, underlying what I call the ‘universalistic’ discourse is the premise that human beings can act in an impartial manner so that all individuals have the capacity to speak or act in the interests of all other individuals regardless of the group(s) to which they belong. On the other hand, a competing discourse based on group-difference’ maintains that all representatives express partial voices depending on their group-based characteristics. I argue that the universalistic discourse was hegemonic in the transcripts but, at the same time, the group-difference discourse was successful at articulating powerful counter-hegemonic resistance. Ironically, the universalistic discourse was hegemonic despite widespread assumptions of partiality on the basis of province, region, language, and Aboriginality. This was possible because the universalistic discourse subsumed territorial notions of partiality within itself. In contrast, I argue that assumptions of Aboriginal partiality will likely diffuse themselves to other categories, beginning with gender, in the future. I also describe the strategies used by the competing discourses to undermine one another. The universalistic discourse successfully portrayed the group-difference discourse as an inversion to a dangerous apartheid-style society where individuals were forced to exist within group-based categories. The group-difference discourse used the strategy of anomaly to demonstrate that individuals were inevitably categorized in the universalistic discourse; impartiality was a facade for a highly-partial ruling class. In examining these strategies, I demonstrate that the group-difference discourse justified its own position by making assumptions about the operation of power and dominance in society. Thus, impartiality was impossible not for the post-modern reason that inherent differences make representation highly problematic, but because power relations hinder the ability of representatives to act in a truly impartial manner.
Band touching from real space topology in frustrated hopping models

description: We study ``frustrated'' hopping models, in which at least one energy band, at the maximum or minimum of the spectrum, is dispersionless. The states of the flat band(s) can be represented in a basis which is fully localized, having support on a vanishing fraction of the system in the thermodynamic limit. In the majority of examples, a dispersive band touches the flat band(s) at a number of discrete points in momentum space. We demonstrate that this band touching is related to states which exhibit non-trivial topology in real space. Specifically, these states have support on one-dimensional loops which wind around the entire system (with periodic boundary conditions). A counting argument is given that determines, in each case, whether there is band touching or not, in precise correspondence to the result of straightforward diagonalization. When they are present, the topological structure protects the band touchings in the sense that they can only be removed by perturbations which {\sl also} split the degeneracy of the flat band.

description: We propose a reliable scheme to recover the conventional photon blockade effect in the dispersive Jaynes-Cummings model, which describes a two-level atom coupled to a single-mode cavity field in the large-detuning regime. This is achieved by introducing a transversal driving to the atom and then photonic nonlinearity is obtained. The eigenenergy spectrum of the system is derived analytically and the photon blockade effect is confirmed by numerically calculating the photon-number distributions and equal-time second-order correlation function of the cavity field in the presence of system dissipations. We find that the conventional photon blockade effect can be recovered at proper atomic and cavity-field drivings. This work will provide a method to generate the conventional photon blockade effect in the dispersively coupled quantum optical systems.

description: We present results from a combined weak lensing and X-ray analysis of the merging cluster A1914 at a redshift of $z=0.1712$ based on $R_{\rm}$-band imaging data with Subaru/Suprime-Cam and archival Chandra X-ray data. Based on the weak-lensing and X-ray data we explore the relationships between cluster global properties, namely the gravitational mass, the bolometric X-lay luminosity and temperature, the gas mass and the gas mass fraction, as a function of radius. We found that the gas mass fractions within $r_{2500}$ and $r_{\rm vir}$ are consistent with the results of earlier X-ray cluster studies and of cosmic microwave background studies based on the WMAP observations, respectively. However, the observed temperature, $k_B T_{\rm ave}=9.6\pm0.3 {\rm keV}$, is significantly higher than the virial temperature, $k_B T_{\rm vir}=4.7\pm0.3 {\rm keV}$ derived from the weak lensing distortion measurement. The X-ray bolometric luminosity and temperature ($L_X-T$) relation is consistent with the $L_X-T$ relation derived by previous statistical X-ray studies of galaxy clusters. Such correlations among the global cluster properties are invaluable observational tools for studying the cluster merger physics. Our results demonstrate that the combination of X-ray and weak-lensing observations is a promising, powerful probe of the physical processes associated with cluster mergers as well as of their mass properties.

description: The magnetohydrodynamics (MHD) equations are continuum models used in the study of a wide range of plasma physics systems, including the evolution of complex plasma dynamics in tokamak disruptions. However, efficient numerical solution methods for MHD are extremely challenging due to disparate time and length scales, strong hyperbolic phenomena, and nonlinearity. Therefore the development of scalable, implicit MHD algorithms and high-resolution adaptive mesh refinement strategies is of considerable importance. In this work, we develop a high-order stabilized finite-element algorithm for the reduced visco-resistive MHD equations based on the MFEM finite element library (mfem.org). The scheme is fully implicit, solved with the Jacobian-free Newton-Krylov (JFNK) method with a physics-based preconditioning strategy. Our preconditioning strategy is a generalization of the physics-based preconditioning methods in [Chacon, et al, JCP 2002] to adaptive, stabilized finite elements. Algebraic multigrid methods are used to invert sub-block operators to achieve scalability. A parallel adaptive mesh refinement scheme with dynamic load-balancing is implemented to efficiently resolve the multi-scale spatial features of the system. Our implementation uses the MFEM framework, which provides arbitrary-order polynomials and flexible adaptive conforming and non-conforming meshes capabilities. Results demonstrate the accuracy, efficiency, and scalability of the implicit scheme in the presence of large scale disparity. The potential of the AMR approach is demonstrated on an island coalescence problem in the high Lundquist-number regime ($\ge 10^7$) with the successful resolution of plasmoid instabilities and thin current sheets.

description: Point to point vacuum correlators containing diquarks in the color anti-triplet representation are computed both in the quenched approximation and dynamical overlap simulations with two flavors. The scalar, pseudoscalar and axial vector diquarks are combined with light quarks to form color singlets. The scalar ("good") diquark channel shows a stronger attraction than the axial vector ("bad") channel in the quenched data set. The pseudoscalar diquark channel shows a finite volume zero mode artifact: the correlator becomes negative at large distance when the quark mass is small. By separating configurations without zero modes from those with zero modes, we found that the zero modes have an important contribution in both the attraction in the scalar channel and the repulsion in the pseudoscalar channel. In the axial vector diquark channel, we did not find apparent zero mode effects.

description: We generate constrained realizations (CRs) of the density and peculiar velocity fields within $200 \; h^{-1} \, \mathrm{Mpc}$ from the final release of the Two-Micron All-Sky Redshift Survey (2MRS) $-$ the densest all-sky redshift survey to date. The CRs are generated by combining a Wiener filter estimator in spherical Fourier-Bessel space with random realizations of log-normally distributed density fields and Poisson-sampled galaxy positions. The algorithm is tested and calibrated on a set of semi-analytic mock catalogs mimicking the environment of the Local Group (LG), to rigorously account for the statistical and systematic errors of the reconstruction method. By comparing our peculiar velocity CRs with the observed velocities from the Cosmicflows-3 catalog, we constrain the normalized linear growth rate to $f σ_8^\mathrm{lin} = 0.367 \pm 0.060$, which is consistent at the $1.1 σ$ level with the latest Planck results as well as other direct probes. Simultaneously, we estimate a bulk flow contribution from sources beyond the 2MRS reconstruction volume of $B^\mathrm{ext} = 199 \pm 68 \; \mathrm{km} \, \mathrm{s}^{-1}$ towards $l = 299 \pm 18^\circ$, $b = 8 \pm 19^\circ$. The total reconstructed velocity field at the position of the LG, smoothed with a $1 \; h^{-1} \, \mathrm{Mpc}$ Gaussian, is $685 \pm 75 \; \mathrm{km} \, \mathrm{s}^{-1}$ towards $l = 270.6 \pm 6.6^\circ$, $b = 35.5 \pm 7.2^\circ$, in good agreement with the observed CMB dipole. The total reconstructed bulk flow within different radii is compatible with other measurements. Within a $50 \; h^{-1} \, \mathrm{Mpc}$ Gaussian window we find a bulk flow of $274 \pm 50 \; \mathrm{km} \, \mathrm{s}^{-1}$ towards $l = 287 \pm 9^\circ$, $b = 11 \pm 10^\circ$. The code used to generate the CRs and obtain these results, dubbed CORAS, is made publicly available.

description: We show that for polytopes P_1, P_2, ..., P_r \subset \R^d, each having n_i \ge d+1 vertices, the Minkowski sum P_1 + P_2 + ... + P_r cannot achieve the maximum of \prod_i n_i vertices if r \ge d. This complements a recent result of Fukuda & Weibel (2006), who show that this is possible for up to d-1 summands. The result is obtained by combining methods from discrete geometry (Gale transforms) and topological combinatorics (van Kampen--type obstructions) as developed in Rörig, Sanyal, and Ziegler (2007).

Τέλος, ασχοληθήκαμε με το νομικό καθεστώς εν Ελλάδι και με όσες ελλείψεις διαπιστώθηκαν κατά την εφαρμογή αλλά και κατά τη διάρκεια της νομοθετικής διαδικασίας.
description: The aim of the present thesis was the study of the institution of “Restorative Justice”. We examined the proposed terminology and the definitions given for this topic. Then we presented the background based on examples throughout history, covering a huge amount of history or geographical aspects. Furthermore, we presented both the pros and the cons on this topic, not only in Greek penal system but globally also. In the end, we examined the Greek laws that integrate Restorative Justice’s practices and mentioned the deficiencies in applying or legislating.
Measurement of prompt D$^{0}$, $Λ_{c}^{+}$, and $Σ_{c}^{0,++}$(2455) production in pp collisions at $\sqrt{s} = 13$ TeV

description: The $p_{\rm T}$-differential production cross sections of prompt D$^{0}$, $Λ_{\rm c}^{+}$, and $Σ_{\rm c}^{0,++}(2455)$ charmed hadrons are measured at midrapidity ($|y| < 0.5$) in pp collisions at $\sqrt{s} = 13$ TeV. This is the first measurement of $Σ_{\rm c}^{0,++}$ production in hadronic collisions. Assuming the same production yield for the three $Σ_{\rm c}^{0,+,++}$ isospin states, the baryon-to-meson cross section ratios $Σ_{\rm c}^{0,+,++}/{\rm D}^{0}$ and $Λ_{\rm c}^{+}/{\rm D}^{0}$ are calculated in the transverse momentum ($p_{\rm T}$) intervals $2 < p_{\rm T} < 12$ GeV/$c$ and $1 < p_{\rm T} < 24$ GeV/$c$. Values significantly larger than in e$^{+}$e$^{-}$ collisions are observed, indicating for the first time that baryon enhancement in hadronic collisions also extends to the $Σ_{\rm c}$. The feed-down contribution to $Λ_{\rm c}^{+}$ production from $Σ_{\rm c}^{0,+,++}$ is also reported and is found to be larger than in e$^{+}$e$^{-}$ collisions. The data are compared with predictions from event generators and other phenomenological models, providing a sensitive test of the different charm-hadronisation mechanisms implemented in the models.

description: The young star AB Aurigae is surrounded by a complex combination of gas-rich and dust dominated structures. The inner disk which has not been studied previously at sufficient resolution and imaging dynamic range seems to contain very little gas inside a radius of least 130 astronomical units (AU) from the star. Using adaptive-optics coronagraphy and polarimetry we have imaged the dust in an annulus between 43 and 302 AU from the star, a region never seen before. An azimuthal gap in an annulus of dust at a radius of 102 AU, along with a clearing at closer radii inside this annulus, suggests the formation of at least one small body at an orbital distance of about 100 AU. This structure seems consistent with crude models of mean motion resonances, or accumulation of material at two of the Lagrange points relative to the putative object and the star. We also report a low significance detection of a point source in this outer annulus of dust. This source may be an overdensity in the disk due to dust accreting onto an unseen companion. An alternate interpretation suggests that the object's mass is between 5 and 37 times the mass of Jupiter. The results have implications for circumstellar disk dynamics and planet formation.

Towards non-perturbative quantization and the mass gap problem for the Yang-Mills Field

description: We reduce the problem of quantization of the Yang-Mills field Hamiltonian to a problem for defining a probability measure on an infinite-dimensional space of gauge equivalence classes of connections on $\mathbb{R}^3$. We suggest a formally self-adjoint expression for the quantized Yang-Mills Hamiltonian as an operator on the corresponding Lebesgue $L^2$-space. In the case when the Yang-Mills field is associated to the Abelian group $U(1)$ we define the probability measure which depends on two real parameters $m>0$ and $c\neq 0$. This yields a non-standard quantization of the Hamiltonian of the electromagnetic field, and the associated probability measure is Gaussian. The corresponding quantized Hamiltonian is a self-adjoint operator in a Fock space the spectrum of which is $\{0\}\cup[\frac12m, \infty)$, i.e. it has a gap.

description: Η υιοθεσία συνιστά ένα καίριο κεφάλαιο του αστικού δικαίου με μεγάλη κοινωνική σημασία. Η λύση της υιοθεσίας και οι συνέπειες της διαγράφονται στα άρθρα 1571 έως 1588 ΑΚ, όπου και συναντάται η λύση της υιοθεσίας είτε ανηλίκου είτε ενηλίκου προσώπου. Επέρχεται είτε αυτοδίκαια είτε δικαστικά. Περαιτέρω, η δικαστική λύση της υιοθεσίας μπορεί να είναι είτε μονομερής είτε συναινετική. Υφίσταται, προκειμένου για δικαστική λύση, η δυνατότητα ανασύστασης της υιοθεσίας. Όταν η υιοθεσία λύεται αυτοδίκαια, ανατρέπεται αυτή αναδρομικά και δεν απαιτείται δικαστική απόφαση που θα απαγγέλει τη λύση. Επιπλέον, η δικαστική λύση επέρχεται για συγκεκριμένους λόγους που αναφέρονται περιοριστικά στο νόμο και απαιτείται η άσκηση αγωγής. Η συναινετική λύση της υιοθεσίας τελείται εφόσον η υιοθεσία έχει διαρκέσει τουλάχιστον ένα έτος και το θετό τέκνο έχει ενηλικιωθεί. Απαιτούνται δυο συζητήσεις, που θα απέχουν μεταξύ τους έξι τουλάχιστον μήνες, και τα μέρη πρέπει να παραστούν στο δικαστήριο αυτοπροσώπως, προκειμένου να συναινέσουν στη λύση της υιοθεσίας. Εφόσον η υιοθεσία λυθεί, ο νόμος προβλέπει την ανασύστασή της, αν εκλείψουν οι λόγοι που την προκάλεσαν και τα μέρη επιθυμούν την επανασύσταση της.
description: Adoption recommends a crucial section of civil law with great social importance. The dissolution of adoption and its consequences are described in articles 1571 to 1588 of Civil Code, where one can find the dissolution of adoption of an a adult and a minor. It occurs whether automatically or judicial. Furthermore, the judicial dissolution of adoption can be whether unilateral or consensual. Εxists, in order for judicial dissolution, the possibility of its reconstruction. When the adoption is being automatically dissolved, reverses back and does not require court order which recites the solution. In addition, the judicial solution occurs for specific reasons, which are mentioned restrictively in the law and requires an action. The consensual dissolution of adoption occurs as long as the adoption has lasted at least one year and the adopted child is an adult. Two judicial discussions are demanded, which will be separated for at least six months and the two sides should be present in court in person, in order to give their consent for the dissolution of the adoption. When that the adoption is dissoluted, the law provides its reconstruction, if the reasons that caused the adoptions dissolution extinct and the two sides wish its reconstruction.

description: The present thesis presents a basic concern created during the course of the second semester in the Interuniversity Postgraduate Programme “Museology”. This concern regards the relationship between the language of exhibition design and the cinematic language. The current study presents the stages of production of a museum exhibition and the language of exhibition design, as well as the stages of production of a film and the cinematic language, so as to lead to the analogies and the similarities between them. The second part presents two examples, one from the museum field and one from the cinema field, so as to lead to the analogies and the similarities in a practical basis. This essay was written as part of the end dissertation Interuniversity Postgraduate Programme “Museology” at Aristotle University of Thessaloniki and contains the necessary elements so as to substantiate the topic of the thesis, the connection between the cinematic and the exhibition design languages.
