description: Nanofibers are an interesting phase into which amphiphilic molecules can self-assemble. Described for a large number of synthetic lipids, they were seldom reported for natural lipids like microbial amphiphiles, known as biosurfactants. In this work, we show that the palmitic acid congener of sophorolipids (SLC16:0), one of the most studied families of biosurfactants, spontaneously forms a self-assembled fiber network (SAFiN) at pH below 6 through a pH jump process. pH-resolved in-situ Small Angle X-ray Scattering (SAXS) shows a continuous micelle-to-fiber transition, characterized by an enhanced core-shell contrast between pH 9 and pH 7 and micellar fusion into flat membrane between pH 7 and pH 6, approximately. Below pH 6, homogeneous, infinitely long nanofibers form by peeling off the membranes. Eventually, the nanofiber network spontaneously forms a thixotropic hydrogel with fast recovery rates after applying an oscillatory strain amplitude out of the linear viscoelastic regime (LVER): after being submitted to strain amplitudes during 5 min, the hydrogel recovers about 80% and 100% of its initial elastic modulus after, respectively, 20 s and 10 min. Finally, the strength of the hydrogel depends on the medium's final pH, with an elastic modulus fivefold higher at pH 3 than at pH 6.

description: Σκοπός της παρούσας εργασίας είναι η διερεύνηση των περιθωρίων που υπάρχουν για να συμβάλουν οι δάσκαλοι και οι δασκάλες, μέσω της διαμόρφωσης της παιδαγωγικής σχέσης, στην κοινωνική αλλαγή. Για το σκοπό αυτό εξετάζεται η παιδαγωγική σχέση ως τρόπος προσέγγισης της γνώσης και πώς μπορεί ως τέτοια να οδηγήσει στη γνωστική χειραφέτηση των μαθητών και των μαθητριών. Έπειτα, προσεγγίζεται η παιδαγωγική σχέση ως τρόπος επικοινωνίας και τονίζονται ορισμένα χαρακτηριστικά που μπορούν να ενισχύσουν την επίτευξη του χειραφετικού περιεχομένου στο γνωστικό επίπεδο. Στη συνέχεια επισημαίνεται και εξετάζεται η αντίφαση της παιδαγωγικής σχέσης και πώς μπορεί να επιτευχθεί η άρση της. Τέλος, γίνεται μια σύντομη προσπάθεια να ανιχνευθεί η σύνδεση της εκπαίδευσης με την κοινωνική αλλαγή, κάτι που – σε συνδυασμό με την διερεύνηση των τρόπων με τους οποίους η παιδαγωγική σχέση αποκτά χειραφετικό χαρακτήρα, η οποία έχει προηγηθεί – οδηγεί στη συνειδητοποίηση της σύνδεσης της αντίφασης της παιδαγωγικής σχέσης με εκείνη του εκπαιδευτικού συστήματος.
description: The purpose of this thesis is to explore the latitude for teachers to contribute to social change by forming the pedagogical relationship. For this purpose, we examine the pedagogical relationship as a way of approaching knowledge and how it can, as such, lead to cognitive emancipation of students. Then, we approach the pedagogical relationship as a way of communication and we highlight some features that can contribute to the achievement of the emancipatory content on the cognitive level. Subsequently, we identify and examine the intrinsic contradiction of the pedagogical relationship and how this contradiction can be resolved. Finally, we briefly attempt to detect the connection between education and social change, which – combined with the aforementioned examination of the ways in which the pedagogical relationship becomes emancipatory – leads to awareness of the connection between the contradiction of the pedagogical relationship to that of the educational system.

description: In the paper, a comparison is described of the microwave power standard based on thermoelectric sensors against an analogous standard based on bolometric sensors. Measurements have been carried out with the classical twin-type microcalorimeter, fitted with N-connector test ports suitable for the frequency band 0.05 - 18 GHz. An appropriate measurand definition is given for being suitable to both standard types. A system accuracy assessment is performed applying the Gaussian error propagation through the mathematical models that interpret the microcalorimeter response in each case. The results highlight advantages and weaknesses of each power standard type.

description: The International Linear Collider (ILC) is likely to provide us important insights into the sector of physics that may supersede our current paradigm viz., the Standard Model. In anticipation of the possibility that the ILC may come up in the middle of the next decade, several groups are vigourously investigating its potential to explore this new sector of physics. The Linear Collider Workshop in Bangalore (LCWS06) had several presentations of such studies which looked at supersymmetry, extra dimensions and other exotic possibilities which the ILC may help us discover or understand. Some papers also looked at the understanding of cosmology that may emerge from studies at the ILC. This paper summarises these presentations.

A Generalized Multigrid Method for Solving Contact Problems in Lagrange Multiplier based Unfitted Finite Element Method

description: Internal interfaces in a domain could exist as a material defect or they can appear due to propagations of cracks. Discretization of such geometries and solution of the contact problem on the internal interfaces can be computationally challenging. We employ an unfitted Finite Element (FE) framework for the discretization of the domains and develop a tailored, globally convergent, and efficient multigrid method for solving contact problems on the internal interfaces. In the unfitted FE methods, structured background meshes are used and only the underlying finite element space has to be modified to incorporate the discontinuities. The non-penetration conditions on the embedded interfaces of the domains are discretized using the method of Lagrange multipliers. We reformulate the arising variational inequality problem as a quadratic minimization problem with linear inequality constraints. Our multigrid method can solve such problems by employing a tailored multilevel hierarchy of the FE spaces and a novel approach for tackling the discretized non-penetration conditions. We employ pseudo-$L^2$ projection-based transfer operators to construct a hierarchy of nested FE spaces from the hierarchy of non-nested meshes. The essential component of our multigrid method is a technique that decouples the linear constraints using an orthogonal transformation of the basis. The decoupled constraints are handled by a modified variant of the projected Gauss-Seidel method, which we employ as a smoother in the multigrid method. These components of the multigrid method allow us to enforce linear constraints locally and ensure the global convergence of our method. We will demonstrate the robustness, efficiency, and level independent convergence property of the proposed method for Signorini's problem and two-body contact problems.

Αντιληφθήκαμε την ατομική ιδιοκτησία μέσω της συσσώρευσης πλούτου και εκμετάλλευσης της εργασίας των άλλων, οι οποίες νομιμοποιούνται μέσω της τυπικής ισότητας των ανθρώπων. Από τις απόψεις που παρατέθηκαν, συμπεραίνουμε ότι το ιδανικό πολίτευμα για τον φιλόσοφο ήταν μια συνταγματική- μεικτή μοναρχία. Παροτρύνει το άτομο στην χειραφέτηση μέσω άσκησης του Λόγου, σέβεται τα φυσικά δικαιώματα και προϋποθέτει την ύπαρξη κοινωνικών σχέσεων, οι οποίες δημιουργούν με τη σειρά τους την ανάγκη ενός αμερόληπτου κριτή για να διασφαλισθεί το ιδιοκτησιακό Δίκαιο. Τονίζει την ανεξαρτησία και αυτονομία έναντι της δουλείας και προτείνει την περιφρούρηση της ιδιοκτησίας και τον σωφρονισμό των παραβατών της. Με αυτόν τον τρόπο κατοχυρώνεται η αναγκαιότητα και νομιμότητα της κοινωνίας. Κεντρική έννοια της διακυβέρνησης είναι η εμπιστοσύνη, η ρήξη της οποίας οδηγεί το λαό στην επανάσταση.
description: The aim of the present thesis was the analysis of Locke’s liberal theory, the individual rights, mainly the property, the representative system and the discrimination of powers. We conceived the individual property via the accumulation of wealth and exploitation of work of other, which is legalized via the formal equality of persons. From the opinions that were mentioned, we conclude that the ideal regime for the philosopher was a constitutional mixed monarchy. It prompts the individual in the emancipation via exercise of Reason, it respects the natural rights and it presupposes the existence of social relations, that creates with their line the need of unbiased critic in order to is ensured the property Right. It stresses the independence and autonomy against the work and proposes the safeguard of property and the punishment of her offenders. In this way are guaranteed the necessity and legality of society. Central significance of governing is the confidence, the rupture of which leads the population to the revolution.

description: The history of research of school textbooks began in the late 19th century in Europe and in a few years on a sufficient number of institutions was founded. The study concludes the report on methodological principles of research and analytical presentation and simultaneous qualitative and quantitative processing of data concerning textbooks. The historical religious references in school textbooks and the individual items of Religion textbooks make the image of religious education in primary education more harmonious and full. The detailed reference to the presence of religions in school books is based on passages that exist in the contents of textbooks and refer to those religions. The multicultural approaches developed, very interesting and innovative teaching proposals aimed at creating a climate of mutual understanding and respect between religions as well as the development of intercultural education.
title: Speculative housebuilding and some aspects of the activities of the speculative housebuilder within the Greater London outer suburban area 1919-1939
Creators: name: Bundock, J. D
Publisher: name: University of Kent

description: Between the two world wars the built-up area of Greater London almost doubled in size. Although a distinct 'suburban trend' became increasingly obvious between 1860 and 1913, the physical dimensions of London's interwar suburban development were far greater than anything previously experienced. In spite of lower residential densities between the wars, a comparison of housebuilding levels before and after The Great War clearly reveals the scale of interwar residential development activity. Thus, in each year between 1871 and 1913 an average of 14,177 dwellings were built within the Metropolitan Police District, 1 while between 1920 and 1937 the annual average. was 41,839. In view of the unparalleled level of housebuilding activity between the wars, it seems extraordinary that the interwar speculative housebuilder and estate developer should have generally escaped the detailed attention of students interested in the history of our urban areas. The 'aim of the present study is to correct, at least in part, this deficiency. The interwar speculative housebuilder and his activities within the Greater London outer suburban area therefore provide the central theme for this work.

description: The successful detection is reported of radial-velocity variations due to orbital motion of the substellar companion of the star tau Bootis, from data obtained with a small aperture (0.4m) telescope and a fibre-fed high-resolution spectrograph. Radial-velocity observations from observing runs in 2000 and 2004 reveal a periodic variation of 3.30 +/-0.02d, which is consistent with the previously determined value of 3.3125 +/-0.0002d. We fit our data to a circular orbit with the known period, and derive a velocity amplitude of 471 +/-10m s-1 (in agreement with the previously published value of 469 +/-5m s-1), and determine a time of maximum velocity (Tmax) of HJD 2453113.95 +/-0.01. These observations explore the minimum system requirements for precise radial-velocity measurements.

description: Fe doping in Ni$_2$Mn$_{1.5}$In$_{0.5}$ results in suppression of the martensitic phase via two contrasting routes. In Ni$_2$Mn$_{1.5-x}$Fe$_{x}$In$_{0.5}$, the martensitic phase is converted to a strain glassy phase, while in Ni$_{2-y}$Fe$_y$Mn$_{1.5}$In$_{0.5}$, a cubic ferromagnetic phase results at the expense of the martensite. Careful studies of magnetic and structural properties reveal the presence of the impurity $γ-$(Fe,Ni) phase as the reason for the emergence of non-ergodic strain glassy phase when Fe is sought to be doped at Y/Z (Mn) sites of X$_2$YZ Heusler alloy. Whereas attempts to dope Fe in the X (Ni) sublattice result in an A2 type antisite disorder that promotes a ferromagnetic ground state.

description: The peculiar behavior of Kondo peak splitting under a magnetic field and bias can be explained by calculating the nonequilibrium retarded Green's function via the nonperturbative dynamical theory (NDT). In the NDT, the application of a lead-dot-lead system reveals that new resonant tunneling levels are activated near the Fermi level and the conventional Kondo peak at the Fermi level diminishes when a bias is applied. Magnetic field causes asymmetry in the spectral density and transforms the new resonant peak into a major peak whose behavior explains all the features of the nonequilibrium Kondo phenomenon. We also show the mechanism of coherent transport through the new resonant tunneling level.

Specifically, we examined the award and its consequences to the successful tenderer. Furthermore, we analyzed the successful tenderer’s means of coercion for the payment of the proceeds of the auctions, and the next in the row auctioning itself. Then we presented the successful tenderer’s protection against legal or real defects of auctioned estate. Another aim of this study was to examine the successful tenderer’s procedural protection to the trials with the object of enforcement and his protection in case of overthrow of seizure. The last theme that we examined was the successful tenderer’s rights after the annulment of the auctioning.

description: For the first time, a direct NLTE analysis of carbon and nitrogen lines in the spectra of nine RR Lyrae stars was carried out. We have determined the abundances of these elements together with oxygen, and have shown that the nitrogen content is increased in metallicity deficient program stars. We conclude that this is a sign of the first dredge up, which occurred at the previous stage of the red giant branch, and brought material processed in an incomplete CNO cycle to the surface of the star. This effect is significantly enhanced by thermohaline (extra-) mixing, which is more effective for metal-poor RR Lyrae stars. This is clearly seen in the plot showing that C/N ration in our sample of stars gradually decreases as metallicity decreases from about --0.2 to --2. Oxygen abundance depends on metallicity in a similar way to what we see in the Population II stars.

description: Polycyclic aromatic hydrocarbons (PAH) are potentially mutagenic and carcinogenic, and as such their exposure is of serious concern. I aimed to study the trends in the levels of selected PAHs in US for the period 2003–2008 and their distribution by gender, race/ethnicity, socioeconomic and smoking status, and by exposure to second-hand smoke (SHS) at home and work. Using data from the National Health and Nutrition Examination Survey, regression models were fitted for 10 individual urinary PAH metabolites. Smoking was statistically significantly associated with higher levels of naphthalene, fluorene, phenanthrene, and pyrene metabolites when compared to non-smokers. SHS exposure at home was also statistically significantly associated with higher concentrations of naphthalene, fluorene, phenanthrene, and pyrene metabolites. There was a statistically significant increase in the concentrations of total naphthalene and fluorene, 2-hydroxynaphthalene, 2- and 9-hydroxyfluorene, 2- and 4-hydroxyphenanthrene, and 1-hydroxypyrene during the study period of 2003–2008. Females were found to have statistically significantly higher concentrations of total naphthalene and phenanthrene metabolites as well as 1- and 2-hydroxynaphthalene, 1-hydroxyphenanthrene, and 1-hydroxypyrene. For most of the PAH metabolites, non-Hispanic whites had the highest adjusted concentrations and Mexican Americans had the lowest adjusted concentrations. For the concentrations of 2-hydroxynaphthalene, however, the reverse was true.

We examined the defense limits, that is to say the necessary measure of the defensive act, with specific mention to the ‘necessary insult’ and to the indicative criteria of determination of the ‘necessary measure of insult’. Then we presented the reduce of the ‘necessary measure of insult’ driven by ‘social-moral restrictions’ and the definition of the extent of defense limits in case of assailant’s kill. Furthermore, we analyzed the encroachment of defense limits, so with the aspect of encroachment of defense as far as its intensity is concerned, as with the aspect of encroachment of defense as far as its extent is concerned. We also examined the defense which although does not really exist, it is supposed to exist and the encroachment of limits of this type of defense, and the prophase of defense. Another aim of this study was to examine the legal effects of the encroachment of defense.

description: Based on the resource theory for quantifying the coherence of quantum channels, we introduce a new coherence quantifier for quantum channels via maximum relative entropy. We prove that the maximum relative entropy for coherence of quantum channels is directly related to the maximally coherent channels under a particular class of superoperations, which results in an operational interpretation of the maximum relative entropy for coherence of quantum channels. We also introduce the conception of sub-superchannels and sub-superchannel discrimination. For any quantum channels, we show that the advantage of quantum channels in sub-superchannel discrimination can be exactly characterized by the maximum relative entropy of coherence for quantum channels. Similar to the maximum relative entropy of coherence for channels, the robustness of coherence for quantum channels has also been investigated. We show that the maximum relative entropy of coherence for channels provides new operational interpretations of robustness of coherence for quantum channels and illustrates the equivalence of the dephasing-covariant superchannels, incoherent superchannels, and strictly incoherent superchannels in these two operational tasks.

description: Στην παρούσα μελέτη επιχειρείται μια σύντομη παρουσίαση των θέσεων της πολιτικής κυρίως θεωρίας γύρω από την αναδυόμενη έννοια των κοινών [commons] ή του κοινού [common] και μια απόπειρα διασύνδεσης της με την σύγχρονη έννομη τάξη και τους θεσμούς της. Η μελέτη διαιρείται σε τρία κυρίως μέρη. Στο πρώτο μέρος γίνεται μια σύντομη ιστορική αναδρομή στην έννοια των κοινών, εξηγείται το πως ξεκίνησε η συζήτηση γύρω από αυτό το θέμα και το γιατί βρέθηκε στο επίκεντρο του ενδιαφέροντος των σύγχρονων μελετητών πολιτικής θεωρίας. Στο δεύτερο μέρος επιχειρείται η παρουσίαση των σημαντικότερων θεωριών για τα κοινά και η οριοθέτηση της έννοιας τους μέσα από τις διάφορες οπτικές και στάσεις της θεωριών αυτών απέναντι στο ζήτημα. Στο τελευταίο μέρος, θίγεται το ζήτημα της διασύνδεσης της θεωρίας των κοινών υφιστάμενους δικαιϊκούς θεσμούς. Κατά κύριο λόγο γίνεται αναφορά στις άδειες ανοιχτού λογισμικού και creative commons ως ένα παράδειγμα μετασχηματισμού του δικαίου και των εννόμων σχέσεων που πηγάζουν από αυτό, προς ένα «δίκαιο των κοινών».
description: The aim of this study was to present the positions of political theory on the emerging concept of “commons” or “common”. The study is divided into three main parts. The first part is a brief historical background to the concept of “commons”. Furthermore, we explain why the concept became widely known. The second part aims to define the “commons” through multiple perspectives and to present the most important political theories concerning this issue. In the last part of the paper, we address the issue of the relation between the theory of commons and the existing juridical institutions. Mainly, we refer to the Open Source and Creative Commons Licenses as salient examples of transformation of law into a “ius communis”.

description: Today ion traps are among the most promising physical systems for constructing a quantum device harnessing the computing power inherent in the laws of quantum physics. The standard circuit model of quantum computing requires a universal set of quantum logic gates for the implementation of arbitrary quantum operations. As in classical models of computation, quantum error correction techniques enable rectification of small imperfections in gate operations, thus allowing for perfect computation in the presence of noise. For fault-tolerant computation, it is commonly believed that error thresholds ranging between 10^-4 and 10^-2 will be required depending on the noise model and the computational overhead for realizing the quantum gates. Up to now, all experimental implementations have fallen short of these requirements. Here, we report on a Molmer-Sorensen type gate operation entangling ions with a fidelity of 99.3(1)% which together with single-qubit operations forms a universal set of quantum gates. The gate operation is performed on a pair of qubits encoded in two trapped calcium ions using a single amplitude-modulated laser beam interacting with both ions at the same time. A robust gate operation, mapping separable states onto maximally entangled states is achieved by adiabatically switching the laser-ion coupling on and off. We analyse the performance of a single gate and concatenations of up to 21 gate operations. The gate mechanism holds great promise not only for two-qubit but also for multi-qubit operations.

description: We have investigated the response of the acoustoelectric current driven by a surface-acoustic wave through a quantum point contact in the closed-channel regime. Under proper conditions, the current develops plateaus at integer multiples of ef when the frequency f of the surface-acoustic wave or the gate voltage Vg of the point contact is varied. A pronounced 1.1 MHz beat period of the current indicates that the interference of the surface-acoustic wave with reflected waves matters. This is supported by the results obtained after a second independent beam of surface-acoustic wave was added, traveling in opposite direction. We have found that two sub-intervals can be distinguished within the 1.1 MHz modulation period, where two different sets of plateaus dominate the acoustoelectric-current versus gate-voltage characteristics. In some cases, both types of quantized steps appeared simultaneously, though at different current values, as if they were superposed on each other. Their presence could result from two independent quantization mechanisms for the acoustoelectric current. We point out that short potential barriers determining the properties of our nominally long constrictions could lead to an additional quantization mechanism, independent from those described in the standard model of 'moving quantum dots'.

description: Co-speech gestures, gestures that accompany speech, play an important role in human communication. Automatic co-speech gesture generation is thus a key enabling technology for embodied conversational agents (ECAs), since humans expect ECAs to be capable of multi-modal communication. Research into gesture generation is rapidly gravitating towards data-driven methods. Unfortunately, individual research efforts in the field are difficult to compare: there are no established benchmarks, and each study tends to use its own dataset, motion visualisation, and evaluation methodology. To address this situation, we launched the GENEA Challenge, a gesture-generation challenge wherein participating teams built automatic gesture-generation systems on a common dataset, and the resulting systems were evaluated in parallel in a large, crowdsourced user study using the same motion-rendering pipeline. Since differences in evaluation outcomes between systems now are solely attributable to differences between the motion-generation methods, this enables benchmarking recent approaches against one another in order to get a better impression of the state of the art in the field. This paper reports on the purpose, design, results, and implications of our challenge.

description: We extended McMillan's Green's function method to study the equilibrium spin current (ESC) in a ferromagnet/ferromagnet (FM/FM) tunnelling junction, in which the magnetic moments in both FM electrodes are not collinear. The single-electron Green's function of the junction system is directly constructed from the elements of the scattering matrix which can be obtained by matching wavefunctions at boundaries. The ESC is found to be determined only by the Andreev-type reflection amplitudes as in the Josephson effect. The obtained expression of ESC is an exact result and at the strong barrier limit gives the same explanation for the origin of ESC as the linear response theory, that is, ESC comes from the exchange coupling between the magnetic moments of the two FM electrodes, ${\mathbf{J}}\sim{\mathbf{h}}_{l}\times{\mathbf{h}}_{r}$. In the weak barrier region, ESC cannot form spontaneously in a noncollinear FM/FM junction when there is no tunneling barrier between the two FM electrodes.

description: Polycyclic aromatic hydrocarbons (PAH) are potentially mutagenic and carcinogenic, and as such their exposure is of serious concern. I aimed to study the trends in the levels of selected PAHs in US for the period 2003–2008 and their distribution by gender, race/ethnicity, socioeconomic and smoking status, and by exposure to second-hand smoke (SHS) at home and work. Using data from the National Health and Nutrition Examination Survey, regression models were fitted for 10 individual urinary PAH metabolites. Smoking was statistically significantly associated with higher levels of naphthalene, fluorene, phenanthrene, and pyrene metabolites when compared to non-smokers. SHS exposure at home was also statistically significantly associated with higher concentrations of naphthalene, fluorene, phenanthrene, and pyrene metabolites. There was a statistically significant increase in the concentrations of total naphthalene and fluorene, 2-hydroxynaphthalene, 2- and 9-hydroxyfluorene, 2- and 4-hydroxyphenanthrene, and 1-hydroxypyrene during the study period of 2003–2008. Females were found to have statistically significantly higher concentrations of total naphthalene and phenanthrene metabolites as well as 1- and 2-hydroxynaphthalene, 1-hydroxyphenanthrene, and 1-hydroxypyrene. For most of the PAH metabolites, non-Hispanic whites had the highest adjusted concentrations and Mexican Americans had the lowest adjusted concentrations. For the concentrations of 2-hydroxynaphthalene, however, the reverse was true.

description: In this paper, by using the notion of negativity, we study the degree of entanglement of a two-level atom interacting with a quantized radiation field, described by the Jaynes-Cummings model (JCM). We suppose that initially the field is in a pure state and the atom is in a general mixed state. In this case the negativity fully captures the entanglement of the JCM. We investigate the case for that the initial state of the field is a coherent state. The influences of the detuning on the degree of entanglement is also examined.

description: Αντικείμενο έρευνας της διπλωματικής εργασίας αποτελεί το δικαίωμα πληροφόρησης του εγγυητή, ιδίως, στη σύμβαση τραπεζικής εγγύησης. Αρχικά αναλύεται η ύπαρξη και το δικαίωμα πληροφόρησης του εγγυητή κατά το στάδιο των διαπραγματεύσεων για την κατάρτιση της σύμβασης εγγύησης και στη συνέχεια το ζήτημα εξετάζεται κατά τη λειτουργία της σύμβασης εγγύησης. Ακολούθως το ζήτημα της πληροφόρησης του εγγυητή προσεγγίζεται υπό το πρίσμα της αρχής της ξενικότητας σε συνδυασμό με την αρχή του «υπεύθυνου δανεισμού». Στη συνέχεια παρουσιάζεται η προστασία του εγγυητή ως καταναλωτή σύμφωνα με τον ν. 2251/1994, ενώ, τέλος, γίνεται μνεία στις ρυθμίσεις του ν. 3869/2010 για τα «υπερχρεωμένα νοικοκυριά» αναφορικά με την έννομη θέση του εγγυητή. Με στόχο την αρτιότερη προσέγγιση του θέματος κατά την παρουσίαση της προβληματικής γίνεται συχνά αναγωγή στα πορίσματα της νομολογίας του ΔΕΕ, καθώς και σε αλλοδαπή βιβλιογραφία και νομολογία, ιδίως γερμανική.
description: The aim of the present thesis is the guarantor’s information right especially at the contract of bank guarantee. Initially the existence and the width of guarantor’s information right during negotiations are analyzed and after this the topic during the operation of the contract is examined. Furthermore, the theme is analyzed from the principal of xenikotita (Fremdheitsprinzip in German legal order) and the principal of “responsible lending” perspective. Afterwards, the guarantor’s protection as a consumer according to the Greek law 2251/1994 is presented and finally the guarantor’s information right according to the Greek law 3869/2010 for the “over indebted households” is mentioned. In order for the topic to be approached in the best way during the presentation, conclusions of EU case law and especially the German one are used.

description: Celestial and momentum space amplitudes for massless particles are related to each other by a change of basis provided by the Mellin transform. Therefore properties of celestial amplitudes have counterparts in momentum space amplitudes and vice versa. In this paper, we study the celestial avatar of dual superconformal symmetry of $\mathcal{N}=4$ Yang-Mills theory. We also analyze various differential equations known to be satisfied by celestial $n$-point tree-level MHV amplitudes and identify their momentum space origins.
Predictors of registration with continuing care and the utilization of support services by family caregivers of Alzheimer’s disease patients

Publisher: name: University of British Columbia
Year: 2008

description: This is a cross-sectional exploratory study designed to examine factors associated with the registration and use of Continuing Care (CC) support services by the caregivers and Alzheimer patients. Registration with CC was related to several of the need characteristics of both the patient and the caregiver. The patient's level of impairment as measured by the Functional Rating Scale (FRS) and the Present Functioning Questionnaire (PFQ) was significantly higher for those patients registered with CC. A greater degree of caregiver burden admeasured by the Zarit Burden Interview was reported by caregivers of patients who were registered with CC. The Burden Interview was subjected to a factor analysis revealing 5 scales measuring different aspects of burden. When examined individually with respect to registration, three of the scales: emotional burden, social intrusion and demand burden surfaced as being significantly associated. It was noted that a total burden score can mask the specific aspects of burden which are related to the outcome. In a closer examination of those who were registered with CC, characteristics of patients and caregivers were examined, comparing those utilizing support services with those not utilizing services. The two groups did not differ significantly with respect to any characteristics. These findings suggest that caregivers may be prone to view registration with CC more as a last resort than a collaborative effort in the interim period. Possible attitudes and perceptions held by caregivers and patients are discussed as influential factors related to utilization practices. Implications for the Canadian Healthcare System and the role of healthcare professionals are also addressed. The need for a longitudinal study is noted due to the dynamic, yet progressive nature of Alzheimer's Disease and the ensuing burden connected with caring for a patient.
