description: We consider a U(2) Yang-Mills theory on M x S_F^2 where M is a Riemannian manifold and S_F^2 is the fuzzy sphere. Using essentially the representation theory of SU(2) we determine the most general SU(2)-equivariant gauge field on M x S_F^2. This allows us to reduce the Yang-Mills theory on M x S_F^2 down to an abelian Higgs-type model over M. Depending on the enforcement (or non-enforcement) of a "constraint" term, the latter may (or may not) lead to the standard critically-coupled abelian Higgs model in the commutative limit, S_F^2 -> S^2. For M = R^2, we find that the abelian Higgs-type model admits vortex solutions corresponding to instantons in the original Yang-Mills theory. Vortices are in general no longer BPS, but may attract or repel according to the values of parameters.

description: We use archived IRAC images from the Spitzer Space Telescope to show that many Class 0 protostars exhibit complex, irregular, and non-axisymmetric structure within their dusty envelopes. Our 8 $μ$m extinction maps probe some of the densest regions in these protostellar envelopes. Many of the systems are observed to have highly irregular and non-axisymmetric morphologies on scales >= 1000 AU, with a quarter of the sample exhibiting filamentary or flattened dense structures. Complex envelope structure is observed in regions spatially distinct from outflow cavities, and the densest structures often show no systematic alignment perpendicular to the cavities. These results indicate that mass ejection is not responsible for much of the irregular morphologies we detect; rather, we suggest that the observed envelope complexity is mostly the result of collapse from protostellar cores with initially non-equilibrium structures. The striking non-axisymmetry in many envelopes could provide favorable conditions for the formation of binary systems. We also note that protostars in the sample appear to be formed preferentially near the edges of clouds or bends in filaments, suggesting formation by gravitational focusing.

description: Die Bearbeitung der tektonischen Übersichtskarte der Zentral- und Südägäis beginnt mit der Klärung des Kartenzwecks, des Benutzerkreises und des Benutzungsvorganges. Aus der Feststellung, daß sich die Karte besonders an Geologen wendet, die der Darstellung sowohl Einzelinformationen entnehmen, als auch einen zusammenfassenden überblick über den tektonischen Bau der Region erhalten wollen, ergibt sich die Forderung nach einer detaillierten und trotzdem übersichtlich gestalteten Darstellung der tektonischen Baueinheiten und der Bruchstrukturen in Verbindung mit dem Relief. Es wird ein Gegenstandskatalog aufgestellt, der in der Karte möglichst zur Darstellung kommen soll. Die Inhaltselemente werden bezüglich ihrer Strukturformen im Grundriß, ihrer Sach- und Lagebeziehungen untereinander und zu den topographischen Elementen hin untersucht. Die Ergebnisse dieser Untersuchung lassen eine systematische Umsetzung der Inhaltselemente in die graphische Zeichensprache zu, wobei Objekt- und Zeichengesetzmäßigkeiten beachtet werden. So wird der optische Eindruck der Karte von den Land- und Meeresfarben gesteuert. Die gegensätzliche Wirkung der warmen und kalten Farben läßt eine Grobgliederung des Kartenbildes zu. Während dieser Gegensatz von Land und Meer und die Bruchstrukturen in Abhängigkeit von morphologischer Gestalt und Untergrund in der obersten Wahrnehmungsebene stehen, rücken die Einzelinformationen über absolute und relative Höhen- oder Tiefenlagen und über die differenzierte Gliederung der tektonischen Einheiten in den Hintergrund. Diese in Wahrnehmungsebenen gestufte Darstellung erleichtert dem Kartenbenutzer das Lesen der Karte. Wesentliches ist hervorgehoben, Unwesentliches zurückgedrängt. Die Herstellung der Karte wird durch den chronologischen Arbeitsablauf dargestellt.

description: Η κατανάλωση αλκοόλ από τους εφήβους αποτελεί ένα φαινόμενο που έχει απασχολήσει πολλούς ερευνητές μέχρι σήμερα. Στην παρούσα διπλωματική εργασία έγινε μια προσπάθεια να μελετηθεί η κατανάλωση αλκοόλ σε ανήλικα κορίτσια που διαμένουν σε δομή φιλοξενίας. Βάση βιβλιογραφίας συσχετίσθηκε η κατανάλωση αλκοόλ από τα ανήλικα κορίτσια με προηγούμενη σεξουαλική κακοποίηση και με την ύπαρξη ψυχικών προβλημάτων. Η μελέτη διεξήχθη σε δείγμα το οποίο συλλέχθηκε από τη Δομή Φιλοξενίας Ασυνόδευτων Ανηλίκων στον οικισμό Πενταλόφου, Κοζάνης, με τελικό δείγμα (Ν=100). Χρησιμοποιήθηκε το πρόγραμμα SPSS και η μέθοδος ανάλυσης χ2 για να βρεθεί αν υπήρχε στατιστική σημαντικότητα μεταξύ των ανεξάρτητων μεταβλητών (σεξουαλική κακοποίηση και ύπαρξη ψυχιατρικής γνωμάτευσης) με την εξαρτημένη μεταβλητή (κατανάλωση αλκοόλ). Βρέθηκε στατιστικώς σημαντική σχέση ανάμεσα στην κατανάλωση αλκοόλ από ανήλικα κορίτσια και τη σεξουαλική κακοποίηση. Επίσης, βρέθηκε στατιστικώς σημαντική σχέση ανάμεσα στην κατανάλωση αλκοόλ από ανήλικα κορίτσια και την ύπαρξη ψυχιατρικής γνωμάτευσης. Κρίνεται βοηθητικό και σκόπιμο να διενεργηθούν επιπλέον μελέτες που θα εξετάζουν ποιοι παράγοντες μπορεί να σχετίζονται με την κατανάλωση αλκοόλ από εφήβους.

description: Alcohol consumption by adolescents is a phenomenon that has occupied many researchers nowadays. In the present study was tried to examine the alcohol consumption of underage girls living in a guest house. Based on the literature, the consumption of alcohol by underage girls was associated with previous sexual abuse and the existence of mental problems. The study was conducted on a sample which was collected from Guest House of Unaccompanied Minors Girls in the settlement of Pentalofos, Kozani, with a final sample (N = 100). To find out if there was a statistical significance between the independent variables (sexual abuse and the presence of psychiatric disorder) with the dependent variable (alcohol consumption) the SPSS program and the x2 analysis method were used. A statistically significant relationship was found between alcohol consumption by underage girls and sexual abuse. Also, a statistically significant relationship was found between the consumption of alcohol by underage girls and the existence of a psychiatric disorder. It would be very helpful to conduct additional studies in the future that will examine which factors may be related to alcohol consumption by adolescents.

description: Iron selenide (FeSex) crystals with lateral dimensions up to millimeters were grown via a vapor self-transport method. The crystals consist of the dominant alpha - phase with trace amounts of beta- phase as identified by powder x-ray diffraction. With four-probe resistance measurements we obtained a zero-resistance critical temperature of 7.5 K and a superconducting onset transition temperature of up to 11.8 K in zero magnetic field as well as an anisotropy of 1.5 +- 0.1 for the critical field. Magnetization measurements on individual crystals reveal the co-existence of superconductivity and ferromagnetism.

Συγκεκριμένα εστιάζει στο πως οι αλγόριθμοι μηχανικής μάθησης μπορούν να επιλύσουν το πρόβλημα της ακύρωσης κρατήσεων δύο ξενοδοχείων της Πορτογαλίας. Αρχικά γίνεται μία εισαγωγή όπου περιγράφονται το πρόβλημα, ο σκοπός και η δομή της διπλωματικής εργασίας. Στη συνέχεια μέσα από τη βιβλιογραφική ανασκόπηση εμβαθύνει στη έννοια της μηχανικής μάθησης και αναλύει τις 3 προσεγγίσεις της: την εποπτευόμενη, τη μη εποπτευόμενη και την ενισχυτική μάθηση.

Τέλος έπειτα από τη εξαγωγή των αποτελεσμάτων καταλήγει σε ορισμένα σημαντικά συμπεράσματα όπως το ότι η προ επεξεργασία των δεδομένων είναι απαραίτητη προϋπόθεση για τη μεγιστοποίηση της ακρίβειας του μοντέλου και της ταχύτητας πρόβλεψης αλλά και ότι ο αλγόριθμος ο οποίος έχει τη μεγαλύτερη ακρίβεια στη συγκεκριμένη έρευνα έχει την χαμηλότερη ταχύτητα εκτέλεσης.
description: The purpose of this thesis is to demonstrate the importance of machine learning in solving the problem of hotel cancellations in Portugal and its modeling. In particular it focuses on how machine learning algorithms can solve the problem of canceling reservations of two hotels in Portugal. First, an introduction is made where the problem, the purpose and the structure of the thesis are described. Then, through the bibliographic review, he delves into the concept of machine learning and analyzes its 3 approaches: supervised, unsupervised and reinforcement learning. . It then proceeds to the research stage following a series of specific steps to solve the problem. It is a classification problem which accepts 31 input data and 1 output data. 4 algorithms are used to maximize prediction accuracy, however Random Forest is the one with the highest accuracy. Python programming language and Weka machine learning software were used to extract the results. Finally, after extracting the results, he comes to some important conclusions such as that the pre-processing of the data is a necessary condition for maximizing the accuracy of the model and the speed of prediction and also that the algorithm which has the most accuracy in this particular research has the lower execution speed.
Dynamical signature of a domain phase transition in a perpendicularly-magnetized ultrathin film

description: Domain phases in ultrathin Fe/Ni/W(110) films with perpendicular anisotropy have been studied using the ac magnetic susceptibility. Dynamics on time scales of minutes to hours were probed by quenching the system from high temperature to the stripe phase region, and varying the constant rate of temperature increase as the susceptibility traces were measured. The entire susceptibility peak is observed to relax slowly along the temperature axis, with the peak temperature increasing as the rate of heating is decreased. This is precisely opposite to what would happen if this slow relaxation was driven by changes in the domain density within the stripe phase. The data are instead consistent with a simple model for the removal of a significant density of pattern defects and curvature trapped in the quench from high temperature. A quantitative analysis confirms that the relaxation dynamics are consistent with the mesoscopic rearrangement of domains required to remove pattern defects, and that the experiment constitutes a "dynamical" observation of the phase transition from a high temperature, positionally disordered phase to the low temperature, ordered stripe phase.

description: We compute, for the first time using lattice QCD methods, radiative transition rates involving excited charmonium states, states of high spin and exotics. Utilizing a large basis of interpolating fields we are able to project out various excited state contributions to three-point correlators computed on quenched anisotropic lattices. In the first lattice QCD calculation of the exotic 1-+ eta_c1 radiative decay, we find a large partial width Gamma(eta_c1 -> J/psi gamma) ~ 100 keV. We find clear signals for electric dipole and magnetic quadrupole transition form factors in chi_c2 -> J/psi gamma, calculated for the first time in this framework, and study transitions involving excited psi and chi_c1,2 states. We calculate hindered magnetic dipole transition widths without the sensitivity to assumptions made in model studies and find statistically significant signals, including a non-exotic vector hybrid candidate Y_hyb? -> eta_c gamma. As well as comparison to experimental data, we discuss in some detail the phenomenology suggested by our results and the extent to which it mirrors that of quark potential models and make suggestions for the interpretation of our results involving exotic quantum numbered states.

description: Language-Driven Engineering (LDE) is a means to model-driven software development by creating Integrated Modeling Environments (IMEs) with Domain/Purpose-Specific Languages (PSLs), each tailored towards a specific aspect of the respective system to be modeled, thereby taking the specific needs of developers and other stakeholders into account. Combined with the powerful potential of full code generation, these IMEs can generate complete executable software applications from descriptive models. As these products themselves may again be IMEs, this approach leads to LDE Ecosystems of modeling environments with meta-level dependencies. This thesis describes new challenges emerging from changes that affect single components, multiple parts or even the whole LDE ecosystem. From a top-down perspective, this thesis discusses the necessary support by language definition technology to ensure that corresponding IMEs can be validated, generated and tested on demand. From a bottom-up perspective, the formulation of change requests, their upwards propagation and generalization is presented. Finally, the imposed cross-project knowledge sharing and transfer is motivated, fostering interdisciplinary teamwork and cooperation. Based on multifaceted contributions to full-blown projects on different meta-levels of an exemplary LDE ecosystem, this thesis presents specific challenges in creating and continuously evolving LDE ecosystems and deduces a concept of PUTD effects to systematically address various dynamics and appropriate actions to manage both product-level requests that propagate upwards in the meta-level hierarchy as well as the downward propagation of changes to ensure product quality and adequate migration of modeled artifacts along the dependency paths. Finally, the effect of language-driven modeling on the increasingly blurred line between building and using software applications is illustrated to emphasize that the distinction between programming and modeling becomes a mere matter of perspective.
Locating the VHE source in the Galactic Centre with milli-arcsecond accuracy

description: Very high-energy gamma-rays (VHE; E>100 GeV) have been detected from the direction of the Galactic Centre up to energies E>10 TeV. Up to now, the origin of this emission is unknown due to the limited positional accuracy of the observing instruments. One of the counterpart candidates is the super-massive black hole (SMBH) Sgr A*. If the VHE emission is produced within ~10^{15} cm ~1000 r_G (r_G=G M/c^2 is the Schwarzschild radius) of the SMBH, a decrease of the VHE photon flux in the energy range 100--300 GeV is expected whenever an early type or giant star approaches the line of sight within ~ milli-arcseconds (mas). The dimming of the flux is due to absorption by pair-production of the VHE photons in the soft photon field of the star, an effect we refer to as pair-production eclipse (PPE). Based upon the currently known orbits of stars in the inner arcsecond of the Galaxy we find that PPEs lead to a systematic dimming in the 100--300 GeV band at the level of a few per cent and lasts for several weeks. Since the PPE affects only a narrow energy band and is well correlated with the passage of the star, it can be clearly discriminated against other systematic or even source-intrinsic effects. While the effect is too small to be observable with the current generation of VHE detectors, upcoming high count-rate experiments like the Cherenkov telescope array (CTA) will be sufficiently sensitive. Measuring the temporal signature of the PPE bears the potential to locate the position and size of the VHE emitting region within the inner 1000 r_G or in the case of a non-detection exclude the immediate environment of the SMBH as the site of gamma-ray production altogether.

description: Electronic transport through a quantum dot chain embodied in an Aharonov-Bohm interferometer is theoretically investigated. In such a system, it is found that only for the configurations with the same-numbered quantum dots side-coupled to the quantum dots in the arms of the interferometer, some molecular states of the quantum dot chain decouple from the leads. Namely, in the absence of magnetic flux all odd molecular states decouple from the leads, but all even molecular states decouple from the leads when an appropriate magnetic flux is introduced. Interestingly, the antiresonance position in the electron transport spectrum is independent of the change of the decoupled molecular states. In addition, when considering the many-body effect within the second-order approximation, we show that the emergence of decoupling gives rise to the apparent destruction of electron-hole symmetry. By adjusting the magnetic flux through either subring, some molecular states decouple from one lead but still couple to the other, and then some new antiresonances occur.

description: We comment on a recent paper by Giacosa, Gutsche, and Lyobovitskij, in which it is argued that a quarkonium interpretation of the $σ$ meson should give rise to a much smaller two-photon decay width than commonly assumed. The reason for this claimed discrepancy is a term in the transition amplitude, necessary for gauge invariance, which allegedly is often omitted in the literature, including the work of the present authors. Here we show their claims to be incorrect by demonstrating, in the context of the Quark-Level Linear $σ$ Model, that the recently extracted experimental value $Γ_{σ\to2γ}=(4.1\pm0.3)$ keV is compatible with a $q\bar{q}$ assignment for the $σ$, provided that meson loops are taken into account as well.

Stabilization of the Electroweak Scale in 3-3-1 Models

description: One way of avoiding the destabilization of the electroweak scale through a strong coupled regime naturally occurs in models with a Landau-like pole at the TeV scale. Hence, the quadratic divergence contributions to the scalar masses are not considered as a problem anymore since a new nonperturbative dynamic emerges at the TeV scale. This scale should be an intrinsic feature of the models and there is no need to invoke any other sort of protection for the electroweak scale. In some models based on the $SU(3)_C\otimes SU(3)_W\otimes U(1)_{X}$ gauge symmetry, a nonperturbative dynamics arise and it stabilizes the electroweak scale.

description: In 2007, a joint IERS/IVS Working Group has been established to consider practical issues of creating the next ICRF generation, ICRF-2. The goal of the WG is to seek after ways to improve the existing ICRF. In this study we investigate a possibility of ICRF improvement by means of using combined ICRF catalogue instead of a catalogue computed in a single analysis centre, even though using most advanced models and software. In this work, we present a new version of Pulkovo combined catalogue of radio source positions computed using the method proposed in \cite{SokMal07}. Radio source catalogues that were submitted in 2007 in the framework of the WG activity were used as input for mutual comparison and combination. Four combined catalogues have been calculated: Two first of them provide a stochastic improvement of the ICRF, and last two of them allow us to account also for systematic errors in the current ICRF version.

Radiation pressure mixing of large dust grains in protoplanetary disks

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: Dusty disks around young stars are formed out of interstellar dust that consists of amorphous, submicrometre grains. Yet the grains found in comets and meteorites, and traced in the spectra of young stars, include large crystalline grains that must have undergone annealing or condensation at temperatures in excess of 1,000 K, even though they are mixed with surrounding material that never experienced temperatures as high as that. This prompted theories of large-scale mixing capable of transporting thermally altered grains from the inner, hot part of accretion disks to outer, colder disk region, but all have assumptions that may be problematic. Here I report that infrared radiation arising from the dusty disk can loft grains bigger than one micrometre out of the inner disk, whereupon they are pushed outwards by stellar radiation pressure while gliding above the disk. Grains re-enter the disk at radii where it is too cold to produce sufficient infrared radiation pressure support for a given grain size and solid density. Properties of the observed disks suggest that this process might be active in almost all young stellar objects and young brown dwarfs.

description: We assess the effects of simulated active galactic nuclei (AGNs) on the colour and morphology measurements of their host galaxies. To test the morphology measurements, we select a sample of galaxies not known to host AGNs and add a series of point sources scaled to represent specified fractions of the observed V band light detected from the resulting systems; we then compare morphology measurements of the simulated systems to measurements of the original galaxies. AGN contributions >20 per cent bias most of the morphology measurements tested, though the extent of the apparent bias depends on the morphological characteristics of the original galaxies. We test colour measurements by adding to non-AGN galaxy spectra a quasar spectrum scaled to contribute specified fractions of the rest-frame B band light detected from the resulting systems. A quasar fraction of 5 per cent can move the NUV-r colour of an elliptical galaxy from the UV-optical red sequence to the green valley, and 20 per cent can move it into the blue cloud. Combining the colour and morphology results, we find that a galaxy/AGN system with an AGN contribution >20 per cent may appear bluer and more bulge-dominated than the underlying galaxy. We conclude that (1) bulge-dominated, E/S0/Sa, and early-type morphology classifications are accurate for red AGN host galaxies and may be accurate for blue host galaxies, unless the AGN manifests itself as a well-defined point source; and (2) although highly unobscured AGNs, such as the quasar used for our experiments, can significantly bias the measured colours of AGN host galaxies, it is possible to identify such systems by examining optical images of the hosts for the presence of a point source and/or measuring the level of nuclear obscuration.

description: This thesis deals with concepts related to energy exchanges. More specifically, starting a historical review, from their foundation to their establishment in the European markets, conditions that contribute to its smooth operation and are in the interest of the consumer will be examined. Through an extensive literature review, an attempt will be made to define concepts that facilitate the smooth operation of energy exchange. Closing the historical review, an overview will be made regarding the situation prevailing in Greece regarding the issue of energy exchanges. Then, through an extensive description, around the operating model, an attempt will be made to establish the Hellenic Energy Exchange and the main entities that make it up, which, in addition to services that are safety valves, for the benefit of the consumer, also function as control tools in the negotiation process. Emphasis will be placed on the role played by RES Aggregator in the energy market in cooperation with all its stakeholders. Finally, concepts such as the balancing market will be clarified, studying how it operates and at the same time how it contributes to the overall package of the market. xBid and the mode of operation will be defined, while in the research part the participation as Res Aggregator in the balancing market will be investigated.
Representative government and the private social welfare agencies : a case study of participation of labour groups in the policy-making processes of Vancouver Red Feather Agencies.
Creators: name: MacLaren, Phyllis Eileen
Publisher: name: University of British Columbia
Year: 2011

description: This study is concerned with the government of private social welfare agencies, and in particular, with the measure of agreement that the conduct of their government shows with the principles of political representation. Diverse and, as yet, imperfectly reconciled theories exist as to the nature of representativeness in government, but for the purposes of this investigation the concept has been specified in terms of a number of selected propositions that would probably be taken as axiomatic in the political traditions of western countries. These include the notions that all enfranchised members of a political society should enjoy the effective right to participation in the choice of their government; that the representative himself is charged to act with a view to the good of the whole group and not with partiality towards some particular and subordinate interest within it; and that the membership has a right to require an accounting from the representative for the manner of his performance in office. The examination of these questions has been annexed in the present study to the special case of the representation on the boards of directors of the private welfare agencies of the segment of the organized, labour movement falling into the relevant jurisdiction. Among the methods used in making the investigation were: (1) a review of the criteria of membership recognized by the private agencies both in their formal constitutions and in their procedural traditions; (2) an assessment of the conduct of the agencies' general meetings when viewed as a mechanism of accountability; 3) an analysis of the composition of the agency boards by certain occupational categories; and (4) a number of interviews with selected union officials, themselves differentiated, on the basis of whether they were members of agency boards or not. The findings of the study are that there is a pervasive ambiguity about the status of the agencies in relation to the formal categories of "private" and "public", that the agencies are unable to render a consistent or plausible account of the theory of political organization to which they hold themselves bound, and that their internal political processes fail to satisfy even those criteria, of legitimacy that they themselves volunteer. The question of the representation of labour groups was held in abeyance for want of agreement in any quarter as to what would constitute evidence for an answer to it.

description: Η μεταναστευτική κρίση λαμβάνει χώρα παγκοσμίως για πάνω από 10 χρόνια. Ωστόσο, τελευταία παρατηρείται μια ραγδαία αύξηση στις μετακινήσεις μεταναστών προς τα εδάφη της Ευρωπαϊκής Ένωσης. Χιλιάδες άτομα συρρέουν στα σύνορα της Ευρώπης με κάθε δυνατό μέσο αναζητώντας ένα καλύτερο μέλλον. Ορισμένοι από αυτούς προέρχονται από εδάφη που βρίσκονται υπό το καθεστώς πολέμου. Άλλοι, όμως αναγκάζονται να μετακινηθούν σε τρίτες χώρες λόγω της εργαλειοποίησης που υφίστανται για πολιτικούς, κυρίως, λόγους. Αμφότεροι στις παραπάνω περιπτώσεις αναζητούν μια καλύτερη ποιότητας ζωής παρόλο που πολλές φορές χρησιμοποιούνται οι ίδιοι ως μοχλός πίεσης μιας χώρας προς κάποια άλλη. Μέσω της εργασίας αυτής θα μελετήσουμε τα αίτια που προκαλούν τις μαζικές μετακινήσεις ανθρώπων με αφορμή κυρίως τις περιπτώσεις της Ουκρανίας και της Ελλάδας οι οποίες αποτελούν διαφορετικά παραδείγματα μετανάστευσης. Έπειτα, θα αναλύσουμε τον τρόπο με τον οποίο οι μετακινήσεις αυτές επηρεάζουν την Ευρώπη καθώς και τις μεθόδους που ακολουθεί αυτή ώστε να επιλύσει το πρόβλημα αυτό. Είναι αλήθεια πως το θέμα της μετανάστευσης μετά τα γεγονότα της Ουκρανίας φαίνεται να έχει αλλάξει σελίδα και κρίνεται αναγκαίο να αλλαχθεί και η αντίληψη που υπάρχει για το προσφυγικό ζήτημα. Με βάση το παραπάνω, θα περιγράψουμε αρχικά τους τρόπους με τους οποίους η Ε.Ε δηλώνει έτοιμη να προσαρμοστεί στα νέα δεδομένα της μετανάστευσης που πλέον κατέχει πρωταρχικό ρόλο στην καθημερινότητά μας, καθώς και την αντιμετώπιση που οφείλει να δείχνει προς τους ανθρώπους αυτούς.
description: The migration crisis has been taking place worldwide for over 10 years. However, recently there has been a rapid increase in the movement of immigrants to the territories of the European Union. Thousands of people are flocking to Europe's borders by any means possible in search of a better future. Some of them come from territories under a state of war. Others, however, are forced to move to third countries due to the instrumentalization that exists for mainly political reasons. Both in the above cases are looking for a better quality of life even though they themselves are often used as a lever of pressure from one country to another. Through this work, we will study the causes that cause the mass movements of people mainly on the occasion of the cases of Ukraine and Greece which are different examples of migration. Then we will analyze how these movements affect Europe and the methods it follows to solve this problem. It is true that the issue of immigration after the events in Ukraine seems to have changed the page and it is deemed necessary to change the perception of the refugee issue. Based on the above, we will initially describe the ways in which the EU declares itself ready to adapt to the new data of immigration which now occupies a primary role in our daily life, as well as the treatment it must show to these people.

description: Mapping CMB polarization is an essential ingredient of current cosmological research. Particularly challenging is the measurement of an extremely weak B-mode polarization that can potentially yield unique insight on inflation. Achieving this objective requires very precise measurements of the secondary polarization components on both large and small angular scales. Scattering of the CMB in galaxy clusters induces several polarization effects whose measurements can probe cluster properties. Perhaps more important are levels of the statistical polarization signals from the population of clusters. Power spectra of five of these polarization components are calculated and compared with the primary polarization spectra. These spectra peak at multipoles $\ell \geq 3000$, and attain levels that are unlikely to appreciably contaminate the primordial polarization signals.
