description: Στην παρούσα μεταπτυχιακή εργασία, διερευνάται αν ένα πρόγραμμα παρέμβασης, με κύριο άξονα τις απεικονίσεις των ανθρώπων σε έργα τέχνης και πολιτισμού, επιδρά θετικά στην δημιουργικότητα παιδιών προσχολικής ηλικίας. Το πρόγραμμα παρέμβασης βασίζεται σε μία ευέλικτη εκπαιδευτική διαδικασία, κατά την οποία, η καλλιτεχνική πράξη πραγματώνεται μέσα από ατομικές, αλλά κυρίως ομαδικές δραστηριότητες των παιδιών. Πρόκειται για μία έρευνα δράσης. Το δείγμα της έρευνας αποτελούν 23 παιδιά, ηλικίας 4-6 ετών, που φοιτούν σε νηπιαγωγείο της Θεσσαλονίκης. Στην παρούσα έρευνα εξετάζεται η δημιουργική διαδικασία, βάσει των ερωτήσεων για την δημιουργική διαδικασία κατά τον Lindström. Πληροφορίες για την δημιουργική διαδικασία αντλούνται από τις απαντήσεις των παιδιών στα ερωτηματολόγια, από την συζήτηση-στοχασμό στο τέλος του κάθε άξονα της παρέμβασης, καθώς και από το φωτογραφικό υλικό. Επίσης, εξετάζονται τα έργα που δημιούργησαν τα παιδιά κατά την διάρκεια της παρέμβασης, σε σχέση με τα έργα που προηγήθηκαν της παρέμβασης, ως προς το κριτήριο της ευκαμψίας. Τα αποτελέσματα της έρευνας είναι θετικά, τόσο ως προς την δημιουργική διαδικασία, όσο και ως προς τα έργα που δημιούργησαν τα παιδιά και αναδεικνύουν την ενίσχυση της δημιουργικής έκφρασης των παιδιών.
description: The present postgraduate paper explores whether an intervention program, with its main part being the representation of people in works of art and culture, can have a positive impact on pre-school children’s creativity. The intervention program is based on a flexible educational process, during which artistic action is carried out through individual and mainly group children’s activities. It is action research. Twenty three (23) children, aged 4-6, who study in a kindergarten school in Thessaloniki, participate in the research. The present research explores the creative process based on Lindström’s questions on the creative process. Information on the creative process is drawn from children’s responses to the questionnaire, from the discussion-brainstorming at the end of every part of the intervention as well as from photographic material. In addition, we examine works made by the children during the intervention and compare them to the works made before the intervention, in terms of the flexibility criterion. The results of the research are positive with respect to the creative process as well as the works created by the children, thus illustrating the reinforcement of children’s creative expression.
The asthmatic athlete: metabolic and ventilatory responses during exercise with and without pre-exercise medication
Creators: name: Ienna, Tiziana Mona

Year: 2009

description: To determine whether asthmatic athletes have normal physiological responses to exercise without pre-exercise medication, we studied 17 female and male asthmatic subjects, 9 highly trained ( HT) (age = 26.1 ± 5.7 yrs; ht = 173.6 ± 10.5 cm; wt = 66.4 ± 10.8 kg; VO₂max = 57.0 ± 4.9 ml.kg-¹.min-¹), and 8 moderately trained (MT) (age = 24.1 ± 3.1 yrs; ht 183.1 ± 11.8 cm; wt = 78.6 ± 15.3 kg; VO₂max = 51.3 ± 4.8 ml•kg⁻¹1min⁻¹ ) with exercise-induced asthma (ETA) under 2 randomly assigned experimental conditions: salbutamol ( S )( 2 puffs = 200ɥg) or placebo (PL) was administered via metered-dose inhaler 15 minutes prior to exercise. The exercise task was 4 continuous 5 minute increments on an electronically braked cycle ergometer representing 25, 50, 75, and 90% of the subject’s VO₂max. VO₂, minute ventilation (VE), respiratory exchange ratio (RER), % saturation (SaO₂), and HR were continuously measured during exercise. A venous catheter was inserted in the subject’s antecubital vein to allow measurement of blood lactate (La) each minute throughout exercise and recovery. Post-medication, exercise, and recovery measurements of peak expiratory flow rates (PEFR) were made using a Mini-Wright flow meter. The data failed to show significance (p > 0.05) between treatment conditions at any stage of exercise with respect to VO₂, VE, RER, HR, and SaO₂. However, among the HT group the mean HR for the 4 exercise conditions was significantly higher under placebo (151.7 (PL) vs. 147.2 (S): p = 0.01). No difference was found in La during exercise or in recovery. Pre-exercise PEFR was significantly higher (582(S) vs. 545 L.sec-’(PL): p =0.003 ) when pretreatment was salbutamol, but prior to treatment there was no difference between the two pre-exercise PEER’s. Mean PEER measures for the exercise and recovery conditions were significantly higher ( 600.1(S) vs. 569.6 (PL): p = 0.002) with the salbutamol treatment. Scheffe’s post-hoc comparisons indicated a significant difference in mean PEER measures with respect to the two treatments between low intensities (25 % and 50 %) and high intensities (75 % and 90 %) of exercise. There was no difference in the physiological response to exercise between groups based on training status. It was concluded that although salbutamol affects the PEER, these asthmatic athletes do not have altered metabolic or ventilatory responses during exercise.
Coupled spin-orbital fluctuations in a three orbital model for $4d$ and $5d$ oxides with electron fillings $n=3,4,5$ -- Application to $\rm NaOsO_3$, $\rm Ca_2RuO_4$, and $\rm Sr_2IrO_4$

description: A unified approach is presented for investigating coupled spin-orbital fluctuations within a realistic three-orbital model for strongly spin-orbit coupled systems with electron fillings $n=3,4,5$ in the $t_{2g}$ sector of $d_{yz},d_{xz},d_{xy}$ orbitals. A generalized fluctuation propagator is constructed which is consistent with the generalized self-consistent Hartree-Fock approximation where all Coulomb interaction contributions involving orbital diagonal and off-diagonal spin and charge condensates are included. Besides the low-energy magnon, intermediate-energy orbiton and spin-orbiton, and high-energy spin-orbit exciton modes, the generalized spectral function also shows other high-energy excitations such as the Hund's coupling induced gapped magnon modes. We relate the characteristic features of the coupled spin-orbital excitations to the complex magnetic behavior resulting from the interplay between electronic bands, spin-orbit coupling, Coulomb interactions, and structural distortion effects, as realized in the compounds $\rm NaOsO_3$, $\rm Ca_2RuO_4$, and $\rm Sr_2IrO_4$.

description: Traditional change detection methods based on convolutional neural networks (CNNs) face the challenges of speckle noise and deformation sensitivity for synthetic aperture radar images. To mitigate these issues, we proposed a Multiscale Capsule Network (Ms-CapsNet) to extract the discriminative information between the changed and unchanged pixels. On the one hand, the capsule module is employed to exploit the spatial relationship of features. Therefore, equivariant properties can be achieved by aggregating the features from different positions. On the other hand, an adaptive fusion convolution (AFC) module is designed for the proposed Ms-CapsNet. Higher semantic features can be captured for the primary capsules. Feature extracted by the AFC module significantly improves the robustness to speckle noise. The effectiveness of the proposed Ms-CapsNet is verified on three real SAR datasets. The comparison experiments with four state-of-the-art methods demonstrated the efficiency of the proposed method. Our codes are available at https://github.com/summitgao/SAR_CD_MS_CapsNet.

Comparative Study of Different Compound Fertilizers on Garlic (Allium Sativum L.) Productivity under Various Soils and Seasons
Creators: name: Diriba-Shiferaw, G.
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Production of good productivity of garlic for both consumption and economic value is the goal of most farmers/producers. However, soil fertility depletion and erratic rainfall are among the major constraints to sustain production of the crop due to limited fertilizer type/sources application and rainfall dependence. Thus, to elucidate this problem a field experiment was conducted to study the effect of different types of compound/blended fertilizers on growth, yields and economic benefits of garlic under both irrigation and rain-fed conditions at DebreZeit Agricultural Research Centre, Ethiopia, on both Andosols and Vertisols in 2013/14. The treatments consisted of control (unfertilized), Diammonium phosphate(NP), Azofertil(NS), Basic(NPKCaO) and D-coder(NPSZn) compound fertilizers each applied at 200kgha-1. The experiment was laidout in randomized complete block design in three replications on both soils.

description: Recent excperiments (ARPES, Raman) suggest the presence of two distinct energy gaps in high-Tc superconductors (HTSC), exhibiting different doping dependences. Results of a variational cluster approach to the superconducting state of the two-dimensional Hubbard model are presented which show that this model qualitatively describes this gap dichotomy: One gap (antinodal) increases with less doping, a behavior long considered as reflecting the general gap behavior of the HTSC. On the other hand, the near-nodal gap does even slightly decrease with underdoping. An explanation of this unexpected behavior is given which emphasizes the crucial role of spin fluctuations in the pairing mechanism.

Challenges of Supply Chain Integration: The Case of Soap and Detergent Manufacturing Companies in EthiopiaChallenges of Supply Chain Integration: The Case of Soap and Detergent Manufacturing Companies in Ethiopia
Creators: name: Gelagay, Daniel Atnafu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: The main objective of this study was to investigate the challenges of supply chain integration in Ethiopia soap and detergent manufacturing companies. To address the research objective, the quantitative survey approach was followed, and target unit of analysis of the study was 25 soap and detergent manufacturing companies. The questionnaire was administered to 75 target respondents to collect the primary data (each company represented by three informants). To analyze the data obtained from respondents’ simple descriptive statistics were applied. Finally, the study found that inflexible organization system, lack of channel trust and commitment, resistance to change and lack of top management commitment were found as supply chain integration challenges in soap and detergent manufacturing firms. In general, the conclusion obtained from this study may not be used to generalize to overall supply chain network performance since its focus is only from the manufacturer’s points of view.
Dwarfs from the Dark (Energy Survey): a machine learning approach to classify dwarf galaxies from multi-band images

description: Countless low-surface brightness objects - including spiral galaxies, dwarf galaxies, and noise patterns - have been detected in recent large surveys. Classically, astronomers visually inspect those detections to distinguish between real low-surface brightness galaxies and artefacts. Employing the Dark Energy Survey (DES) and machine learning techniques, Tanoglidis et al. (2020) have shown how this task can be automatically performed by computers. Here, we build upon their pioneering work and further separate the detected low-surface brightness galaxies into spirals, dwarf ellipticals, and dwarf irregular galaxies. For this purpose, we have manually classified 5567 detections from multi-band images from DES and searched for a neural network architecture capable of this task. Employing a hyperparameter search, we find a family of convolutional neural networks achieving similar results as with the manual classification, with an accuracy of 85% for spiral galaxies, 94% for dwarf ellipticals, and 52% for dwarf irregulars. For dwarf irregulars - due to their diversity in morphology - the task is difficult for humans and machines alike. Our simple architecture shows that machine learning can reduce the workload of astronomers studying large data sets by orders of magnitudes, as will be available in the near future with missions such as Euclid.

We address here two questions, asked in [DR] and in ([DH1], [DH2]) respectively, about the asymptotic behaviour of such diffusions. More generally, we establish a central limit theorem for a class of Minkowskian diffusions, to which the two above ones belong. As a consequence, we correct a partially wrong guess in [DH1].

Nat Turner after 9/11: Kyle Baker's Nat Turner

Subjects: Nat Turner

post-9/11

description: Scholars have thoroughly questioned what Nat Turner meant to others in the past; in this article, I question
what he means today. Reversing William Andrews's injunction to read “Prophet Nat's” 1831 insurrection through the
US's encounter with religio-political terrorism on 9/11, I instead examine the effect September 11th has had on the
rebel slave's contemporary afterlife. Ultimately this article asks what cultural work Nat Turner now performs, what
his most recent depictions tell us about the racial formations of the present. Drawing on comics theory, I parse the
visual rhetoric of Kyle Baker's popular and increasingly studied comic Nat Turner, in which Baker tropes Nat Turner
as Christ just as Nat Turner himself did in his Confessions. Baker produces an inviolably iconic black hero, one who
is visually antithetical to racist images of “the terrorist" circulating in post-9/11 discourses on national belonging. By
doing so, Baker effectively safeguards not only Nat Turner but US "blackness" from Islamophobia during the age of
the Global War on Terror. Finally, by reading Baker's comic alongside other recent, unexamined depictions of the
rebel slave, this article critically intervenes by updating the archive on Nat Turner and complicating the political
possibilities that inhere in other sites of memory.

description: The aim of this thesis is to present the environmental risks arising from the transportation of oil by sea and the contribution of green shipping practices to the reduction of greenhouse gases’ emissions. First of all, marine oil pollution is analyzed. In the second chapter, the system of liability and compensation, which is in force according to International Conventions, is examined. The main purpose of this system is to provide a complete compensation to the victims of marine oil pollution. The next chapter is dedicated to the air pollution, which is caused by ships in general. The relevant regulations of MARPOL 73/78 are analyzed. These regulations target to the prevention of harmful emissions from ships. In the last chapter, green shipping practices are examined. These practices can contribute to the reduction of greenhouse gases’ emissions from ships. The categories of measures that can be put into effect are mentioned and some examples, for each of them, are developed.
Garlic nutrient management in Ethiopia - a review
Creators: name: G Diriba-Shiferaw
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: The main aim of this review is to provide an overview of the garlic crop productivity and its production management requirements like soil, climate and fertilization in general and specifically in Ethiopia, comparing them with current research trends and to indicate future benefits of soil nutrient management investigations. The application of balanced nutrients under optimum moisture availability in different soil types is an important crop management strategy, which may help maximizing crop yield and quality. Also, lack of optimum nutrients and moisture in the soil has been the major bottlenecks of garlic production and productivity; since the crop has a very shallow root system that requires frequent irrigation and fertilization with different types of fertilizers under various soil types. Low soil fertility is one of the principal and pervasive constraints to garlic production in Ethiopia; thus, there are differences among soil types in yielding ability under different nutrients and soil characteristics. Most smallholder farmers in Ethiopia appreciate the value of fertilizers, but they seldom apply them at the recommended rates and at the appropriate time according to the soil characteristics. These are because of high cost, lack of credit, delivery delays, and low and variable returns. In addition, the traditional organic inputs, like crop residues and animal manures, it cannot meet crop nutrient demand over large areas because of the limited quantities available, the low nutrient content of the materials, and the high labor demands for processing and application. However, it is possible to increase garlic crop yields through identification/selection of soil type and balanced nutrients application or searching for other nutrients sources beyond Urea and Diammonium phosphate especially in Ethiopian condition. Therefore, the integrated use of both the organic and inorganic fertilizers was felt as the best option to increase both yield potential and quality of garlic crop.

description: COVID-19 pandemic has been raging all around the world for almost a year now, as of November 1, 2020. In this paper, we try to analyze the variation of the COVID-19 pandemic in different countries in the light of some modifications to the susceptible-infected-recovered (SIR) model. The SIR model was modified by taking time-dependent rate parameters. From this modified SIR model, the basic reproduction number, effective reproduction number, herd immunity, and herd immunity threshold are redefined. The re-outbreak of the COVID-19 is a real threat to various countries. We have used the above-mentioned quantities to find the reasons behind the re-outbreak of this disease. Also, the effectiveness of herd immunity to prevent an epidemic has been analyzed with respect to this model. We have also tried to show that there are certain universal aspects in the spread and containment of the disease in various countries for a short period of time. Finally, we have also analyzed the current pandemic situation in India and have attempted to discuss the possibilities in order to predict its future behaviour using our model.

description: We present new results from our test of Lorentz invariance, which compares two orthogonal cryogenic sapphire microwave oscillators rotating in the lab. We have now acquired over 1 year of data, allowing us to avoid the short data set approximation (less than 1 year) that assumes no cancelation occurs between the $\tildeκ_{e-}$ and $\tildeκ_{o+}$ parameters from the photon sector of the standard model extension. Thus, we are able to place independent limits on all eight $\tildeκ_{e-}$ and $\tildeκ_{o+}$ parameters. Our results represents up to a factor of 10 improvement over previous non rotating measurements (which independently constrained 7 parameters), and is a slight improvement (except for $\tildeκ_{e-}^{ZZ}$) over results from previous rotating experiments that assumed the short data set approximation. Also, an analysis in the Robertson-Mansouri-Sexl framework allows us to place a new limit on the isotropy parameter $P_{MM}=δ-β+{1/2}$ of $9.4(8.1)\times10^{-11}$, an improvement of a factor of 2.

description: Fractures occur in the shoulder area, which has a wider range of motion than other joints in the body, for various reasons. To diagnose these fractures, data gathered from Xradiation (X-ray), magnetic resonance imaging (MRI), or computed tomography (CT) are used. This study aims to help physicians by classifying shoulder images taken from X-ray devices as fracture / non-fracture with artificial intelligence. For this purpose, the performances of 26 deep learning-based pretrained models in the detection of shoulder fractures were evaluated on the musculoskeletal radiographs (MURA) dataset, and two ensemble learning models (EL1 and EL2) were developed. The pretrained models used are ResNet, ResNeXt, DenseNet, VGG, Inception, MobileNet, and their spinal fully connected (Spinal FC) versions. In the EL1 and EL2 models developed using pretrained models with the best performance, test accuracy was 0.8455,0.8472, Cohens kappa was 0.6907, 0.6942 and the area that was related with fracture class under the receiver operating characteristic (ROC) curve (AUC) was 0.8862,0.8695. As a result of 28 different classifications in total, the highest test accuracy and Cohens kappa values were obtained in the EL2 model, and the highest AUC value was obtained in the EL1 model.

description: Background: Breast cancer is the leading cause of cancer related deaths among women worldwide. Diagnosis of breast cancer at an earlier stage allows women more treatment choices and greater chance of long term survival. Breast self-examination (BSE) once a month contributes to a woman’s heightened awareness of what is normal for her. It is recommended that women over the age of 20 years perform monthly breast self-examination to detect new lumps and other changes in their breast. In view of the fact that mammography is not readily available in resource limited countries like Ethiopia, this study was designed to assess Knowledge, Attitude and Practice of regular Breast self-examination amongst female health science students of Adama science and Technology University in 2014. Methodology : A cross-sectional study design was used to select 368 study subjects randomly. Self-administered questionnaires were used to collect information. The collected data were entered into Epi-info version 3.5.1. After cleaning the data it was exported to SPSS version 21 for further analysis. Bivariate and multivariate analyses were also performed with logistic regression to measure the association between dependent and independent variables. Result: A total of 368 respondents participated in the study, of these, only 8.7% of them had good knowledge and 59.2% had positive attitude towards BSE. About two fifth (39.4%) of the respondents had done breast self- examinations, from these only 9.7% of them practiced monthly. Statistically significant association was obtained only with, level of education of the participant, father’s educational level and program of enrolment. Conclusion and recommendation : Knowledge and practice of BSE was low, even though majority of them have positive attitude. Being health was the major mentioned reasons for not doing BSE. The ministry of health is recommended to promote awareness about BSE through emergence of groups in the University, celebrating days like breast cancer day.

description: Green's functions with continuum spectra are a way of avoiding the strong bounds on new physics from the absence of new narrow resonances in experimental data. We model such a situation with a five-dimensional model with two branes along the extra dimension $z$, the ultraviolet (UV) and the infrared (IR) one, such that the metric between the UV and the IR brane is AdS$_5$, thus solving the hierarchy problem, and beyond the IR brane the metric is that of a linear dilaton model, which extends to $z\to\infty$. This simplified metric, which can be considered as an approximation of a more complicated (and smooth) one, leads to analytical Green's functions (with a mass gap $m_g \sim \textrm{TeV}$ and a continuum for $s > m_g^2$) which could then be easily incorporated in the experimental codes. The theory contains Standard Model gauge bosons in the bulk with Neumann boundary conditions in the UV brane. To cope with electroweak observables the theory is also endowed with an extra custodial gauge symmetry in the bulk, with gauge bosons with Dirichlet boundary conditions in the UV brane, and without zero (massless) modes. All Green's functions have analytical expressions and exhibit poles in the second Riemann sheet of the complex plane at $s=M_n^2-i M_nΓ_n$, denoting a discrete (infinite) set of broad resonances with masses ($M_n$) and widths ($Γ_n$). For gauge bosons with Neumann or Dirichlet boundary conditions, the masses and widths of resonances satisfy the (approximate) equation $s= - 4 m_g^2 \mathcal W_n^2[\pm (1+i)/4]$, where $\mathcal W_n$ is the $n$-th branch of the Lambert function.

description: Το ωταιμάτωμα είναι η συλλογή αίματος μεταξύ του δέρματος και του χόνδρου της έσω επιφάνειας του πτερυγίου του αυτιού. Σκοπός της εργασίας είναι η αναδρομική μελέτη 53 περιστατικών ωταιματώματος σε σκύλους και γάτες, οι οποίες αντιμετωπίστηκαν χειρουργικά στην Κλινική των ζώων Συντροφιάς του Α.Π.Θ. Από τα 53 περιστατικά ζώων με ωταιμάτωμα 48 ήταν σκύλοι και 5 γάτες. Τα δεδομένα περιλαμβάνουν στοιχεία των ζώων, συνοδά νοσήματα, θεραπεία, μετεγχειρητικές επιπλοκές και εξέλιξη του περιστατικού. Από τους 48 σκύλους, με μέση ηλικία τα 7,6 έτη, 16 ήταν ακαθόριστης φυλής, 10 ήταν GSD, 3 ήταν French Bulldog και οι υπόλοιποι διαφόρων φυλών. Από τις 5 γάτες, με μέση ηλικία 5 έτη, 1 ήταν περσική ενώ οι άλλες 4 ήταν ακαθόριστης φυλής. Από τις γάτες 3 είναι αρσενικές, και 2 θηλυκές ενώ από τους σκύλους 31 ήταν αρσενικοί και 17 θηλυκοί. Είκοσι τρείς σκύλοι και 3 από τις 5 γάτες εμφάνιζαν παράλληλα έξω ωτίτιδα. Όλα τα ζώα αντιμετωπίστηκαν χειρουργικά με παροχέτευση του αιματώματος με σωλήνα Penrose. 7 σκύλοι και 1 γάτα παρουσίασαν υποτροπή του ωταιματώματος μετεγχειρητικά, και αντιμετωπίστηκαν με επανατοποθέτηση σωλήνα Penrose. Συνολικά καλή εξέλιξη είχαν όλα τα περιστατικά μετά από διάμεση μετεγχειρητική παρακολούθηση 3,5 ετών για τους σκύλους και 4,5 ετών για τις γάτες
description: The records of 53 cases of dogs and cats presented in the Companion Animal Clinic of the Aristotle University of Thessaloniki with an aural hematoma treated with Penrose drainage were reviewed. Data collected include signalment, concurrent disease, treatment, post-surgical complications and long- term outcome. Common canine breeds represented were 16 mixed breed, 10 GSDs and 3 French Bulldogs. Four cats were DSH and one was a Persian. Mean age of the dogs was 7.6 years and of the cats was 5 years. Three cats and 31 dogs were male, while 2 cats and 17 dogs were female. Otitis externa was diagnosed in 23 dogs and 3 cats and skin disease was diagnosed in 11 dogs and 1 cat. All dogs and cats had a Penrose drain placed within the hematoma cavity. Recurrence of hematoma was reported in 7 dogs and 1 cat. Those animals were treated with revision drainage of the hematoma and placement of a new Penrose tube. Pinna deformation was diagnosed in 14 dogs and 2 cats. No signs of hematoma were reported after a follow up time of 3.5 years for dogs and 4.5 years for cats.

description: We present the Australian Square Kilometre Array Pathfinder (ASKAP) localization and follow-up observations of the host galaxy of the repeating fast radio burst (FRB) source, FRB20201124A, the fifth such extragalactic repeating FRB with an identified host. From spectroscopic observations using the 6.5-m MMT Observatory, we derive a redshift of $z=0.0979 \pm 0.0001$, a star formation rate inferred from H$α$ emission of SFR(H$α$) $\approx 2.1 M_{\odot}$ yr$^{-1}$, and a gas-phase metallicity of 12+log(O/H)$\approx 9.0$. By jointly modeling the 12-filter optical-mid-infrared (MIR) photometry and spectroscopy of the host, we infer a median stellar mass of $\approx 2 \times 10^{10} M_{\odot}$, internal dust extinction of $A_V\approx 1-1.5$ mag, and a mass-weighted stellar population age of $\approx 5-6$ Gyr. Connecting these data to the radio and X-ray observations, we cannot reconcile the broad-band behavior with strong AGN activity and instead attribute the dominant source of persistent radio emission to star formation, likely originating from the circumnuclear region of the host. The modeling also indicates a hot dust component contributing to the MIR luminosity at a level of $\approx 10-30\%$. We model the host galaxy's star formation and mass assembly histories, finding that the host assembled $>90\%$ of its mass by 1 Gyr ago and exhibited a fairly constant SFR for most of its existence, with no clear evidence of past star-burst activity.

description: Cross-streamline non-inertial migration of a vesicle in a bounded Poiseuille flow is investigated experimentally and numerically. The combined effects of the walls and of the curvature of the velocity profile induce a movement towards the center of the channel. A migration law (as a function of relevant structural and flow parameters) is proposed that is consistent with experimental and numerical results. This similarity law markedly differs from its analogue in unbounded geometry. The dependency on the reduced volume $ν$ and viscosity ratio $λ$ is also discussed. In particular, the migration velocity becomes non monotonous as a function of $ν$ beyond a certain $λ$.

description: We show a way to perform the canonical renormalization group (RG) prescription in tensor space: write down the tensor RG equation, linearize it around a fixed-point tensor, and diagonalize the resulting linearized RG equation to obtain scaling dimensions. The tensor RG methods have had a great success in producing accurate free energy compared with the conventional real-space RG schemes. However, the above-mentioned canonical procedure has not been implemented for general tensor-network-based RG schemes. We extend the success of the tensor methods further to extraction of scaling dimensions through the canonical RG prescription, without explicitly using the conformal field theory. This approach is benchmarked in the context of the Ising models in 1D and 2D. Based on a pure RG argument, the proposed method has potential applications to 3D systems, where the existing bread-and-butter method is inapplicable.

description: Η παρούσα εργασία αφορά σε διδακτική παρέμβαση που έλαβε χώρα το σχολικό έτος 2016-2017 με μαθητές/τριες της Γ΄ Γυμνασίου στο πλαίσιο του μαθήματος Κείμενα Νεοελληνικής Λογοτεχνίας. Στόχος ήταν οι μαθητές/τριες μέσα από συγκεκριμένες στρατηγικές δημιουργικής ανάγνωσης και γραφής να προσεγγίσουν τη λογοτεχνία και να γίνουν μέτοχοι του λογοτεχνικού αγαθού. Οι δράσεις έγιναν ως επί το πλείστον στον χώρο της σχολικής τάξης και της σχολικής βιβλιοθήκης και ορισμένες εκτός σχολικού περιβάλλοντος. Το αποτέλεσμα ήταν οι μαθητές/τριες να δημιουργήσουν ένα δικό τους «εκδοτικό προϊόν», ένα ανθολόγιο κειμένων δημιουργικής γραφής και μια θεατρική παράσταση με την παρουσία και δικών τους κειμένων δημιουργικής γραφής επί σκηνής. Η έρευνα παρακολουθεί όλη τη διαδικασία της εκπαιδευτικής παρέμβασης, όπως αυτή εγγράφεται μέσα στο πλαίσιο της διδακτικής διαδικασίας. Τα ευρήματα της έρευνας καταδεικνύουν επίσης τον βαθμό αξιοποίησης στοιχείων και υλικών από πάσχοντες ήρωες των σχολικών και όχι μόνο κειμένων που κατάφεραν οι μαθητές να χρησιμοποιήσουν σε δικά τους κείμενα δημιουργικής γραφής, καθώς και την αξιοποίηση μηχανισμών και τεχνικών από ορισμένα κειμενικά είδη με τα οποία ήρθαν σε επαφή κατά το σχολικό έτος 2016-2017.
description: The current paper (project) concerns the teaching intervention that took place during the school year 2016-2017 with male and female students of the 3rd grade of secondary school within the course of “Texts of Modern Greek Literature”. The aim of the project was for the students to approach literature and become shareholders of the literary good, through specific strategies of creative reading and writing. The actions took place mostly in their classroom and the school library while some of them were done outside of the school environment. As a result, the students – both boys and girls – created their own “editorial product”, an anthology of creative writing texts as well as a theatrical performance with the presentation of their own creative writing texts on stage. The research follows the whole procedure of the educational intervention, as it is recorded in the frame of the teaching procedure. The findings of the research also show the degree of data and material exploitation from suffering heroes of school – and not only – texts, which the students managed to use in their own creative writing texts, as well as the exploitation of mechanisms and techniques by specific text articles which they came in contact with during the school year 2016-2017.
