description: Effects from nonstandard corrections to Newtonian gravity, at large scale, can be investigated using the cosmological structure formation. In particular, it is possible to show if and how a logarithmic correction (as that induced from nonlocal gravity) modifies the clustering properties of galaxies and of clusters of galaxies. The thermodynamics of such systems can be used to obtain important information about the effects of such modification on clustering. We will compare its effects with observational data and it will be demonstrated that the observations seem to point to a characteristic scale where such a logarithmic correction might be in play at galactic scales. However, at larger scales such statistical inferences are much weaker, so that a fully reliable statistical evidence for this kind of corrections cannot be stated without further investigations and the use of more varied and precise cosmological and astrophysical probes.

description: We describe the public release of the Cluster Monte Carlo Code (CMC) a parallel, star-by-star $N$-body code for modeling dense star clusters. CMC treats collisional stellar dynamics using Hénon's method, where the cumulative effect of many two-body encounters is statistically reproduced as a single effective encounter between nearest-neighbor particles on a relaxation timescale. The star-by-star approach allows for the inclusion of additional physics, including strong gravitational three- and four-body encounters, two-body tidal and gravitational-wave captures, mass loss in arbitrary galactic tidal fields, and stellar evolution for both single and binary stars. The public release of CMC is pinned directly to the COSMIC population synthesis code, allowing dynamical star cluster simulations and population synthesis studies to be performed using identical assumptions about the stellar physics and initial conditions. As a demonstration, we present two examples of star cluster modeling: first, we perform the largest ($N = 10^8$) star-by-star $N$-body simulation of a Plummer sphere evolving to core collapse, reproducing the expected self-similar density profile over more than 15 orders of magnitude; second, we generate realistic models for typical globular clusters, and we show that their dynamical evolution can produce significant numbers of black hole mergers with masses greater than those produced from isolated binary evolution (such as GW190521, a recently reported merger with component masses in the pulsational pair-instability mass gap).

description: This work analyzed genome-wide nucleotide distribution patterns in ten insect genomes. Two internal measures were applied: (i) GC variation and (ii) third codon nucleotide preference. Although the genome size and overall GC level did not show any correlation with insect order, the internal measures usually displayed higher levels of consistency. GC variations in genomes of hymenopteran insects, honeybee and wasp, ranked highest among all eukaryotic genomes analyzed by us. Genomes of honeybee and beetle, insects of different orders with similar overall GC levels, showed significant internal differences. Honeybee genome stood out as unusual due to its high GC variation and 'left-handed' gene locations.

description: In unparticle dark matter (unmatter) models the equation of state of the unmatter is given by $p=ρ/(2d_U+1)$, where $d_U$ is the scaling factor. Unmatter with such equations of state would have a significant impact on the expansion history of the universe. Using type Ia supernovae (SNIa), the baryon acoustic oscillation (BAO) measurements and the shift parameter of the cosmic microwave background (CMB) to place constraints on such unmatter models we find that if only the SNIa data is used the constraints are weak. However, with the BAO and CMB shift parameter data added strong constraints can be obtained. For the $Λ$UDM model, in which unmatter is the sole dark matter, we find that $d_U > 60$ at 95% C.L. For comparison, in most unparticle physics models it is assumed $d_U<2$. For the $Λ$CUDM model, in which unmatter co-exists with cold dark matter, we found that the unmatter can at most make up a few percent of the total cosmic density if $d_U<10$, thus it can not be the major component of dark matter.

Monitoring and control of milling with an open architecture computer numerical controller
Creators: name: Munasinghe, Watukarage Kamal
Publisher: name: University of British Columbia
Year: 2009

description: The importance of an Open Architecture design of a Computer Numerical Controller for integration of process monitoring and control for unmanned intelligent machining is demonstrated. The Hierarchical Open Architecture Multiprocessor Computer Numerical Controller (HOAM-CNC), which is used in this thesis has been designed and built in the Manu facturing Automation Laboratory of UBC. Basic milling process monitoring and control modules which are adaptive force control, tool breakage detection, chatter detection and suppression have been integrated to HOAM-CNC system for intelligent machining. Adaptive force control module keeps the peak cutting force at a specified reference level by manipulating the feed. The purpose of adaptive force control is to avoid shank failure of the cutter and to increase machining accuracy. Tool breakage monitoring system is based on the residuals of two first order adaptive time series filters. Filters remove the effect of geometric transients from average forces. In the event of a tool breakage the residuals simultaneously violate their own adaptive thresholds. Chatter detection and suppression algorithm uses the frequency spectrum of sound emitting from the cutting process. The presence of chatter vibrations is detected when the spectrum amplitude exceeds a predetermined threshold level. The system automatically reduces the depth of cut until chatter vibrations diminish. All three process monitoring and control functions run in parallel in the proposed open architecture system. Performance of the complete CNC system is tested by intelligent machining of a pocket.

description: We present the results the photometric observations of the Type IIP supernova SN 2012aw obtained for the time interval from 7 till 371 days after the explosion. Using the previously published values of the photospheric velocities we've computed the hydrodynamic model which simultaneously reproduced the photometry observations and velocity measurements. The model was calculated with the multi-energy group radiation hydrodynamics code STELLA. We found the parameters of the pre-supernova: radius $R = 500 R_\odot$, nickel mass $M(^{56}$Ni$)$ $\sim 0.06 M_\odot$, pre-supernova mass $25 M_\odot$, mass of ejected envelope $23.6 M_\odot$, explosion energy $E \sim 2 \times 10^{51}$ erg. The model progenitor mass $M=25 M_\odot$ significantly exceeds the upper limit mass $M=17 M_\odot$, obtained from analysis the pre-SNe observations. This result confirms once more that the 'Red Supergiant Problem' must be resolved by stellar evolution and supernova explosion theories in interaction with observations.

title: A neoliberalizing Chinese cinema: political economy of the Chinese film industry in post-WTO China
Creators: name: Zhu, Xiaoxi
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2019

description: This thesis aims to investigate the industry restructuration of the Chinese film industry in the context of China integrating into the global neoliberal capitalist system since its WTO entry in 2002. By interrogating the power dynamics between the Party-state, domestic capital and transnational media capital, this thesis explores respective roles each of the three stakeholders have played in shaping the commercialization and marketization of the Chinese film industry. Methodically, this thesis primarily relies on elite interviews with industry professionals, together with critical discourse analysis of one key policy document, and secondary data collected from news outlets, trade publications, industry reports, etc. Drawing on the empirical data, I present four main arguments. First, in light of China’s culture system reform and the evolution of film policies since 2002, the Party-state continues to utilize film as an ideological instrument for consolidating the Party’s hegemonic rule and sustaining its legitimacy. The Party-state proves ingenious in governing the Chinese film industry at the discursive level as China experiencing the integration into global neoliberalism. Second, despite the installation of the market mechanism in the film sector, the Party-state manages to retain control over the Chinese film industry, not only on the ideological front, but also in the economic sense by partaking in the competition with private capital, domestic and foreign. Third, the Chinese film industry has been profoundly transformed by the trend of conglomeration driven by other capital-intensive industry sectors in China, in particular the internet sector. Riding on their explosive success in the new century, several key tech giants seek to build Chinese media conglomerates that are competitive on the global scale. This process is further complicated by the keen participation of transnational media capital, mainly Hollywood players. Co-production film projects best epitomize the transnational collaboration which however, haven’t achieved much success. Fourth, the Chinese film workers have developed professional skills that enable them to navigate between political imperatives, commercial demands, and personal fulfilment. The mental struggle of balancing individual artistic vision with political and commercial constraints is palpable for film practitioners on a daily basis, though to varying degree. One way of coping with the challenge is exercise agency in a highly depoliticized manner, channelling creative energy into filmmaking activities that are either considered politically safe, or in accordance with the official ideologies, in some cases pandering to the Party-state. The fact that Chinese film workers actively transform themselves into depoliticized subjects in their professional work, indicating neoliberalism as a national hegemonic project at its core.

description: The challenge of designing and implementing of a multilateral learning platform through distinctive application scenarios – by considering the needs of individual stakeholders and future users – can be addressed by a holistic approach. A suitable platform requires adequate solutions with regard to how and in which settings we learn or teach; how we access, maintain and use our personal data; how we produce, access, reuse and exchange content; the skills and competences that are reflected in curricula or by employers; the feedback, e-assessment and certification; social interactions, communities of practice and personal learning networks; maintenance, data ownership and operational funding Therefore, this paper has the following structure: In the section “Objectives, Procedures and Methods of Instructional Design”, the requirementsof users, institutions and organizations with regard to the intended way of learning and teaching, and under consideration of various settings are explained. The aim is to empower the users for life-long learning and raise their awareness in relation to culture bias, data protection and sustainable long-term operation are laid out. The "Requirements and Potentials" are stated in the third section. Subsequently, the paper examines the “Prerequisites for Inclusive Education”, “General and Institutional Requirements”, aspects of “Profiling, Matching and Learning Path Recommendation”. Dedicated Learning Networks and Social Interactions” and their key role in the process of learning, importance of “Recognition, Validation and Accreditation” before ending the section by describing factors of a solution for “Sustainable and Trustworthy Long-Term Operation” The “Results” are summarized in section four, and section five sketches a possible plan of “Implementation”. Finally, the proposal concludes with “Next Steps” and the bibliography of cited “Refer- ences”. The paper takes the perspective of the individual learner (teacher, user) and provides the relevant prospects of the organizations (University, Ministry of Education, nation, UNICEF, etc.).
Extreme-ultraviolet bursts and nanoflares in the quiet-Sun transition region and corona

description: The quiet solar corona consists of myriads of loop-like features, with magnetic fields originating from network and internetwork regions on the solar surface. The continuous interaction between these different magnetic patches leads to transient brightenings or bursts that might contribute to the heating of the solar atmosphere. However, it remains unclear whether such transients, which are mostly observed in the EUV, play a significant role in atmospheric heating. We revisit the open question of these bursts as a prelude to the new high-resolution EUV imagery expected from the recently launched Solar Orbiter. We use EUV images recorded by the SDO/AIA to investigate statistical properties of the bursts. We detect the bursts in the 171 Å filter images of AIA in an automated way through a pixel-wise analysis by imposing different intensity thresholds. By exploiting the high cadence (12 s) of the AIA observations, we find that the distribution of lifetimes of these events peaks at about 120 s. The sizes of the detected bursts are limited by the spatial resolution, which indicates that a larger number of events might be hidden in the AIA data. We estimate that about 100 new bursts appear per second on the whole Sun. The detected bursts have nanoflare-like energies of $10^{24}$\,erg per event. Based on this, we estimate that at least 100 times more events of a similar nature would be required to account for the energy that is required to heat the corona. When AIA observations are considered alone, the EUV bursts discussed here therefore play no significant role in the coronal heating of the quiet Sun. If the coronal heating of the quiet Sun is mainly bursty, then the high-resolution EUV observations from Solar Orbiter may be able to reduce the deficit in the number of EUV bursts seen with SDO/AIA at least partly by detecting more such events.

Ως επιμέρους στόχοι τέθηκαν οι κάτωθι: Εάν και κατά πόσο επηρεάζει το κινητικό προφίλ των μαθητών α) το φύλο β) ο τόπος διαμονής και γ) το κυρίαρχο χέρι. Στην έρευνα συμμετείχαν 69 μαθητές, ηλικίας 7 – 13 ετών. Οι 33 εξ αυτών (47,8%) διαγνωστήκαν με μαθησιακές δυσκολίες και αποτέλεσαν την ομάδα παρέμβασης και οι υπόλοιποι 36 (52,2%) χωρίς μαθησιακές δυσκολίες, αποτέλεσαν την ομάδα ελέγχου. Από το σύνολο των μαθητών 35 ήταν τα αγόρια (50,7%) και 34 τα κορίτσια (49,3%). Όλες οι μετρήσεις πραγματοποιήθηκαν σε σχολεία του Νομού Φλώρινας. Ως εργαλείο μέτρησης χρησιμοποιήθηκε το κινητικό τεστ «MABC – 2 Movement Assessment Battery For Children 2». Για την ανάλυση των δεδομένων χρησιμοποιήθηκε το στατιστικό πακέτο SPSS έκδοση 21. Σύμφωνα με τα αποτελέσματα στις ζώνες αυξημένου κινδύνου του MABC-2 εντάχθηκαν μόνο οι συμμετέχοντες της ομάδας παρέμβασης, σε ποσοστό 17,3%. Οι συμμετέχοντες χωρίς μαθησιακές δυσκολίες παρουσίασαν καλύτερο κινητικό προφίλ και σε όλους τους επιμέρους κινητικούς τομείς του MABC-2. Επιπρόσθετα η κινητικότητα των συμμετεχόντων τόσο η λεπτή όσο και η αδρή, δεν επηρεάστηκε από τους παράγοντες φύλο, τόπο διαμονής και κυρίαρχο χέρι. Συμπερασματικά επιβεβαιώνεται ότι μόνο οι μαθητές με Μ.Δ παρουσίασαν χαμηλότερο κινητικό προφίλ σε σχέση με τους μαθητές χωρίς Μ.Δ.
description: The purpose of this research is to examine the correlation between learning difficulties and motor skills of school aged children. In addition to the main purpose, the research explores the influence of gender, place of residence and dominant hand of the children to their motor skills. The survey involved 69 students aged from 7 to 13 years old, where 33 of them (47.8%) had learning difficulties and composed the experimental group and 36 (52.2%) didn’t have learning difficulties and were the control group. From all the students, 35 were boys (50.7%) and 34 were girls (49.3%). The assessment of the children took place in schools of the Municipality of Florina and as a measurement tool was used the “MABC-2 Movement Assessment Battery for Children 2” test. The SPSS version 21 statistical package was used for the statistical analysis. According to the results, 17.3% of the participants were in the increased risk zones and all of them came from the experimental group. Participants without learning difficulties presented a better motor profile in all MABC-2 sub-areas. In addition, the mobility of the participants was not influenced by gender, place of residence and dominant hand. In conclusion, it is confirmed that only students with learning difficulties have a lower motor profile than the students without learning difficulties

description: In recent years there has been an increase in the number of refugees entering our country every day. War is the root cause of this great increase that leads to economic deprivation of families who are forced to leave their country. Poverty, but also the different cultural background of these people, can lead to their social exclusion. Intercultural education aims to reduce or even eliminate this phenomenon by setting as its main objective the limitation of injustice and rejection through school integration, which can in turn lead to social inclusion.

description: Due to human activities a variety of different air pollutants are released into the air. Significant sources of emissions are industry, energy sector and traffic. The traffic sector has different emission sources and is not only related to road traffic. However, while there are many studies that describe the air pollution caused by road traffic, there are only a few studies which describe the emissions released by airports. The Laboratory for Environmental Measurement Techniques of the Düsseldorf University of Applied Sciences performed a case-study to investigate the amount of emissions generated by airport activities. The campaign was carried out during October 2018 for the Environmental State Agency of North-Rhine-Westphalia (LANUV). The aim was to investigate the temporal and the spatial variation of emissions released by the Düsseldorf Airport with a main focus on the release of ultrafine particles (UFP). Therefore, we used a combined strategy in form of stationary and mobile measurements. Additional to the ground-based measurements, a research-aircraft flight was performed in order to investigate the downwind UFP-plume of the airport. Two measurement stations were positioned at the north and south border of the airport to measure the temporal variation of the particle number concentration. These stations were equipped with an SMPS (TSI NanoScan) and a discMini (testo). Additionally, In order to investigate the spatial distribution in the surrounding areas an e-bike was equipped with a discMini (testo), miniWRAS (Grimm/Durag), aethalometer (Aethlabs), cavity-DOAS (IUP Heidelberg), windsonic (Gill instruments), GPS device and a camera. With this e-bike predefined routes were cycled, starting with a full round along the border of the airport. Depending on the actual wind direction, the second part of the route covered areas that were located downwind to the airport. The first results show that the amount of emissions from the airport for species like nitrogen dioxide, soot and coarse particles are on a moderate level. In contrast to that, the amount of ultrafine particles released by the airport resulted in greatly increased values. The data show a typical trend of UFP concentrations, which is characterized by an immediate increase in parallel to the beginning of air traffic in the morning hours, a stay on a high level during the day and a decrease to a typical background concentration level in the late evening, when the air traffic stops due to night flight ban at the Düsseldorf Airport. The wind has a strong influence on the spread of the emissions, so that significantly increased UFP concentrations could be measured up to several kilometers away downwind to the airport. The results of this study indicate that the main part of the UFP emissions is released by the jet engines of the aircraft and the amount of the UFP emissions correlates with the frequency of air traffic.
Design and development of a high pressure CNG intensifier
Creators: name: Touchette, Alain
Publisher: name: University of British Columbia
Year: 2009

description: A two-Stage, variable-stroke rotary-reciprocating intensifier was built in order to provide high pressure natural gas to a diesel engine. In this application, the intake pressure is variable (20 to 200 bar), as is the mass flow (2 to 50 kg/hr) and the delivery pressure is constant (200 bar). The main feature of this intensifier is that it can provide any mass flow in this range regardless of intake pressure or operating speed. The mechanism used to provide the variable mass flow uses a variable stroke. This mechanism, as well as the intensifier configuration, was chosen after investigating the alternative design concepts. This investigation showed that the variable stroke would be an energy efficient method of controlling the intensifier mass flow. The specific intensifier dimensions were determined using a graphical design optimization technique. Prototype testing was limited to speeds below its design operating range because of component failures due to inadequate cooling. In this speed range, the variable stroke proved to be capable of controlling the intensifier mass flow. The rotary-reciprocating geometry was not as energy efficient as originally expected. This shOrtfall is due to large frictional losses in the rotary gas seals and roller bearings. These frictional losses are essentially constant for all strokes which results in low efficiencies at low mass flows. It is suggested that a new intensifier design be considered: a configuration which retains the variable stroke capability of the rotary reciprocating design but eliminates the main sources of frictional losses by using non-rotating pistons.

description: Recent studies in three dimensional spintronics propose that the Œrsted field plays a significant role in cylindrical nanowires. However, there is no direct report of its impact on magnetic textures. Here, we use time-resolved scanning transmission X-ray microscopy to image the dynamic response of magnetization in cylindrical Co$_{30}$Ni$_{70}$ nanowires subjected to nanosecond Œrsted field pulses. We observe the tilting of longitudinally magnetized domains towards the azimuthal Œrsted field direction and create a robust model to reproduce the differential magnetic contrasts and extract the angle of tilt. Further, we report the compression and expansion, or breathing, of a Bloch-point domain wall that occurs when weak pulses with opposite sign are applied. We expect that this work lays the foundation for and provides an incentive to further studying complex and fascinating magnetization dynamics in nanowires, especially the predicted ultra-fast domain wall motion and associated spin wave emissions.

Στο πλαίσιο της μεταπτυχιακής εργασίας μας δημιουργείται μια πειραματική ιστοσελίδα (αναζήτησης – ευρετηρίασης). logothiki.web.auth.gr Σκοπός του ιστότοπου ευρετηρίασης είναι να βοηθήσει πιστούς και ερευνητές στην αναζήτηση ομιλιών και να αναδείξει τη σημασία που έχουν για την επιστήμη της Θεολογίας και ειδικότερα του κλάδου της Πατρολογίας οι ομιλίες των εσχάτων χρόνων. Παράλληλα με την κατασκευή του ιστότοπου γίνεται παρουσίαση του βίου και του έργου οκτώ (8) συγχρόνων αγιορειτών Πατέρων οι οποίοι είναι οι εξής: Όσιος Παΐσιος Αγιορείτης, Όσιος Πορφύριος Καυσοκαλυβίτης, Γέροντας Ιωσήφ Βατοπαιδινός, Γέροντας Εφραίμ Κατουνακιώτης, Γέροντας Αιμιλιανός Σιμωνοπετρίτης, Γέροντας Εφραίμ Φιλοθεΐτης, Γέροντας Γεώργιος Γρηγοριάτης, Γέροντας Μωυσής Αγιορείτης.
description: The archives, audio and audiovisual, are Christian literary evidence. Today's technology allows us to record and store digitally something that was previously passed through many copier hands, a lot of dangers, and great effort to get our critical release in our hands. Today, recording and filming can relieve the next researchers from the critical edition, but not from searching for and locating the evidence. In the context of our postgraduate work, an experimental website (search - indexing) is created. logothiki.web.auth.gr The purpose of the indexation site is to help believers and researchers in the search for speeches and to highlight the importance of the lectures of the late years on the science of Theology and especially the patrology sector. Together with the construction of the site, the presentation of the life and work of eight (8) modern Fathers of Mount Athos is presented: Saint Paisius Athonite, Saint Porphyrius the Kafsokalyvitis, Elder Joseph Vatopaidinos, Elder Ephraim Katounakiotis, Elder Aimilianos Simonopetritis, Elder Efraim filotheitis, Elder George Gregoriatis, Elder Moses Hagiorite.

description: Neutron stars are known to host extremely powerful magnetic fields. Among other effects, one of the consequences of harbouring such fields is the deformation of the neutron star structure, leading, together with rotation, to the emission of continuous gravitational waves. On the one hand, the details of their internal magnetic fields are mostly unknown. Likewise, their internal structure, encoded by the equation of state, is highly uncertain. Here we present a study of axisymmetric models of isolated magnetised neutron stars, for various realistic equations of state considered viable by observations and nuclear physics constraints. We show that it is possible to find simple relations between the magnetic deformation of a neutron star, its Komar mass and its circumferential radius. Such relations are quasi-universal, meaning that they are mostly independent on the equation of state of the neutron star and only slightly dependent on the magnetic field configuration. Being formulated in terms of potentially observable quantities, as we discuss, our results could help to constrain the magnetic properties of the neutron star interior and to better assess the detectability of continuous gravitational waves by isolated neutron stars, without knowing their equation of state. Our results are derived both in general relativity and in scalar-tensor theories - one of the most promising extensions of general relativity - in this case by considering also the scalar charge. We show that even in this case general relations hold that account for deviations from general relativity, that could potentially be used to set constraints on the gravitational theory.

An origin for small neutrino masses in the NMSSM

description: We consider the Next to Minimal Supersymmetric Standard Model (NMSSM) which provides a natural solution to the so-called mu problem by introducing a new gauge-singlet superfield S. We realize that a new mechanism of neutrino mass suppression, based on the R-parity violating bilinear terms mu_i L_i H_u mixing neutrinos and higgsinos, arises within the NMSSM, offering thus an original solution to the neutrino mass problem (connected to the solution for the mu problem). We generate realistic (Majorana) neutrino mass values without requiring any strong hierarchy amongst the fundamental parameters, in contrast with the alternative models. In particular, the ratio |mu_i/mu| can reach about 10^-1, unlike in the MSSM where it has to be much smaller than unity. We check that the obtained parameters also satisfy the collider constraints and internal consistencies of the NMSSM. The price to pay for this new cancellation-type mechanism of neutrino mass reduction is a certain fine tuning, which get significantly improved in some regions of parameter space. Besides, we discuss the feasibility of our scenario when the R-parity violating bilinear terms have a common origin with the mu term, namely when those are generated via a VEV of the S scalar component from the couplings lambda_i S L_i H_u. Finally, we make comments on some specific phenomenology of the NMSSM in the presence of R-parity violating bilinear terms.

description: Among all insect genomes, honeybee displays one of the most unusual patterns with interspersed long AT and GC-rich segments. Nearly 75% of the protein-coding genes are located in the AT-rich segments of the genome, but the biological significance of the GC-rich regions is not well understood. Based on an observation that the bee miRNAs, actins and tubulins are located in the GC-rich segments, this work investigated whether other highly conserved genomic regions show similar preferences. Sequences ultraconserved between the genomes of honeybee and Nasonia, another hymenopteran insect, were determined. They showed strong preferences towards locating in the GC-rich regions of the bee genome.

description: The Time Dependent Boltzmann equation (TDBE) is a viable option to study strongly out-of-equilibrium thermalization dynamics which are becoming increasingly critical for many novel physical applications like Ultrafast thermalization, Terahertz radiation etc. However its applicability is greatly limited by the impractical scaling of the solution to its scattering integral term. In our previous work\cite{Michael} we had proposed a numerical solver to calculate the scattering integral term in the TDBE and then improved on it\cite{1DPaper} to include second degree momentum discretisation and adaptive time stepping. Our solver requires no close-to-equilibrium assumptions and can work with realistic band structures and scattering amplitudes. Moreover, it is numerically efficient and extremely robust against inherent numerical instabilities. While in our previous work \cite{1DPaper} we showcased the application of our solver to 1D materials, here we showcase its applications to a simple 2D system and analyse thermalisations of the introduced out-of-equilibrium excitations. The excitations added at higher energies were found to thermalise faster than those introduced at relatively lower energies. Also, we conclude that the thermalisation of the out-of-equilibrium population to equilibrium values is not a simple exponential decay but rather a non-trivial function of time. Nonetheless, by fitting a double exponential function to the decay of the out-of-equilibrium population with time we were able to generate quantitative insights into the time scales involved in the thermalisations.

Microaggressions: a necessity
Creators: name: Pohorence, Allison
Publisher: name: No Publisher Supplied
Year: 2021

description: Microaggressions are a controversial topic. Some agree that this concept is useful, while others insist that the word itself invites aggression into a conversation, and that the concept makes people more aware and defensive of these subtle, back-handed racist remarks. I propose that microaggressions are a concept worth studying, as the trauma that microaggressions cause could be prevented if people were educated and trained properly on how to prevent microaggressions before they ever begin. Furthermore, the training will also educate people on how to show compassion after they have committed the microaggression and how to handle the situation appropriately. This paper will also address those who are in support of microaggressions and relay their facts and statistics to the reader. I will also address those that suggest that education and training is not necessary on this topic. I will rebuke their sentiments with facts and data that illustrate how damaging microaggressions can be, and that their recommendations of abandoning this word is the worst idea possible.

description: Η παρούσα μεταπτυχιακή διπλωματική εργασία επικεντρώθηκε στις παρεμβάσεις του κράτους, είτε κατ’ εφαρμογή των μνημονιακών δεσμεύσεων είτε κατ’ επιταγή διεθνών νομικών κειμένων, στο ελληνικό τραπεζικό σύστημα για πληροφοριακούς, εισπρακτικούς και άλλους σκοπούς, επιβάλλοντας περιορισμούς στα ατομικά δικαιώματα, σε μια προσπάθεια αντιμετώπισης των επιπτώσεων της παγκόσμιας οικονομικής κρίσης, κυρίως της φοροδιαφυγής αλλά και προς το σκοπό της βελτίωσης της ελληνικής οικονομίας και την κατάσταση του δημοσιονομικού ελλείμματος. Εξετάσαμε το κατά πόσο είναι θεμιτές αυτές οι παρεμβάσεις, δεδομένου ότι θίγουν συνταγματικώς κατοχυρωμένα δικαιώματα, υπό ποιες προϋποθέσεις και μέχρι ποιο σημείο, κάνοντας ιδιαίτερη αναφορά στην έννοια του δημοσίου συμφέροντος και τη διάσταση που αυτή έχει λάβει κατά την πρόσφατη νομολογία. Αναλύσαμε, επίσης, το θεσμό του τραπεζικού απόρρητου και τις διαστάσεις του στην προστασία των οικονομικών συμφερόντων των πελατών ενός πιστωτικού ιδρύματος και συγκεντρώσαμε τις νομικές διατάξεις που επιβάλλουν την άρση του χάριν δημοσίου συμφέροντος. Μελετήσαμε το πλέγμα των νομοθετικών διατάξεων που δίδει ευρεία δυνατότητα στο Δημόσιο να εισάγει περιορισμούς στο τραπεζικό απόρρητο, με αναφορές στην πρόσφατη νομολογία. Τέλος, ασχοληθήκαμε με την κατάσχεση των οφειλών προς το Δημόσιο στα χέρια των πιστωτικών ιδρυμάτων ως τρίτων και τα ιδιαίτερα προνόμια που έχει στη διαδικασία είσπραξης των απαιτήσεών του
description: The present Master’s thesis was focused on the interventions of the State, whether imposed by the Memorandum’s commitments or by International Law, in the Greek Banking System for informative, collective and other purposes, imposing restrictions to individual rights, in an effort to confront the consequences of the global economic crisis, mainly the tax evasion and with the aim to improve the greek economy and the situation of fiscal deficit. We examined whether these interventions are legal, due to the fact that offend constitutional rights, under which circumstances and in which point, with specific reference to the meaning of public interest and the dimension that has taken in the current case law. We also analyzed the principal of Bank Secrecy and the dimensions of the protection of the financial interests of the clients of a financial institution and we gathered the legal provisions that impose the revocation of Bank Secrecy for the public interest. We examined the complex of the legal provisions that gives the authority to the State to enforce restrictions to Bank Secrecy, with references to the current case law. In the end, we referred to the forfeiture of the debts to the Sate on financial institutions as third parties and the special privileges of the State in the procedure of collecting debts

description: Στα πλαίσια της παρούσας διπλωματικής εργασίας εξετάστηκε η σύμβαση εγγυήσεως και η διατήρηση της ευθύνης των εγγυητών. Πιο συγκεκριμένα, εστιάσαμε στον παρεπόμενο χαρακτήρα της σύμβασης εγγύησης και στις συνέπειες που έχει για τον εκάστοτε εγγυητή, η υπαγωγή του πρωτοφειλέτη, σε προπτωχευτικές ή πτωχευτικές διαδικασίες εξυγίανσης αλλά και στην πτώχευση. Για το σκοπό αυτό κρίθηκε σκόπιμο να αναφερθούμε σε κάποιες από τις βασικές αρχές της σύμβασης εγγυήσεως, προκειμένου εν συνεχεία να προσπαθήσουμε να προσεγγίσουμε την εγγύηση, μέσα από τις διατάξεις του ν.3588/2007 (Πτωχευτικός Κώδικας και εφεξής ΠτΚ) και του ν. 3869/2010. Τέλος, η προσέγγιση της ευθύνης των εγγυητών στα πλαίσια των προπτωχευτικών ή πτωχευτικών διαδικασιών εξυγίανσης και της πτώχευσης βασίστηκε στην σύγκριση του ισχύοντος (ΠτΚ) με το προϊσχύον δίκαιο (ν. 1892/1990)
description: In the context of this thesis examined the security agreement and the maintenance responsibility of the guarantors. More specifically, we focused on ancillary warranty contract and on the consequences for the respective guarantor, the inclusion of the debtor, in pre-bankruptcy reorganization or bankruptcy proceedings and also in bankruptcy. For this purpose it is appropriate to mention some of the basic principles of the Convention guarantee, in order to approach the guarantee, through the provisions of n.3588/2007 (Bankruptcy Code and hereafter SRS) and Law 3869 / 2010. Finally, the approach to the liability of the guarantors under the pre- bankruptcy reorganization or bankruptcy proceedings and the bankruptcy was based on the comparison of the current (SRS) with the pre-existing law (Law 1892/1990)
