description: Projects have a significant position in the course of language learning in Greece the latest years. This assignment, in its first segment, examines theoretically the projects as a modern method of teaching, presenting their characteristics, advantages, the difficulties that may arise during their preparation or application, as well as the steps-differentiations-phases of the teaching procedure. After that, the projects and their use are examined extensively as part of the foreign language learning course and how they are intergraded in the syllabi of the European and Greek schools. Some criteria for their further analysis have emerged from the theoretical analysis of projects, that has already been done. Based on these data, the suggested projects of the school handbook “Deutsch -ein Hit!2”are presented and adapted for the lesson of German as a second foreign language taught in Greek high schools. Eventually, new ways of projects’ application are suggested and also intergraded in the lesson plans for the same school handbook.

description: The notion of a double well potential typically involves two regions of space separated by a repulsive potential barrier. The solution is a wave function that is suppressed in the barrier region and localized in the two surrounding regions. Remarkably, we illustrate that similar solutions can be achieved using an attractive "barrier" potential (a "quantum moat") instead of a repulsive one (a "quantum wall"). The reason this works is intimately connected to the concepts of "orthogonalized plane waves" and the pseudopotential method, both originally used to understand electronic band structures in solids. While the main goal of this work is to use a simple model to demonstrate the barrier-like attribute of a quantum moat, we also show how the pseudopotential method is used to greatly improve the efficiency of constructing wave functions for this system using matrix diagonalization.

description: Η παρούσα μελέτη επιδίωξε την αποτύπωση των παιδαγωγικών απόψεων του γερμανού φιλοσόφου Immanuel Kant, όπως αυτές παρουσιάζονται στο έργο του με τίτλο «Περί Παιδαγωγικής», και την διεξαγωγή συμπερασμάτων αναφορικά τόσο με τη θεωρία που είχε αναπτύξει αλλά και τον ίδιο του τον χαρακτήρα. Οι παιδαγωγικές του απόψεις συνδέονται με τη φιλοσοφία του και δεν συνιστούν απλώς ορισμένες παρατηρήσεις αναφορικά με τη θεματική της αγωγής. Άλλωστε, όπως αναδεικνύεται από το έργο του, η έννοια της αγωγής προσεγγίζεται ολιστικά, καθώς ξεκινά από την ανατροφή του παιδιού και ολοκληρώνεται με τις σεξουαλικές και κοινωνικές διακρίσεις τις οποίες αντιλαμβάνεται ο άνθρωπος, ενώ ενδιάμεσα η θεματολογία ποικίλει από ζητήματα τιμωρίας και αξιοπρέπειας, έως ζητήματα διαμόρφωσης μίας ηθική και θρησκευτικής αγωγής στο παιδί. Επίσης, η αγωγή δε μελετάται απομονωμένα από το κοινωνικό περιβάλλον της εποχής, καθώς γίνονται αναφορές σε ιδρύματα, πρόσωπα και κοινωνικές συνήθειες, ενώ παράλληλα ασκείται κριτική στους έχοντες, αλλά και σε πιο ιδιαίτερα ζητήματα, όπως αυτό της θρησκείας.
description: This study attempted to capture the pedagogical views of the German philosopher Immanuel Kant, as presented in his work entitled "Kant’s Pedagogy ', and draw conclusions regarding both the theory he had developed and his own character. The pedagogical aspects related to philosophy and not merely constitute some remarks on the subject of treatment. Moreover, as highlighted by his work, the concept of education is approached holistically, as he embarks on the upbringing of the child and ends with sexual and social discrimination which realizes the man, while the intermediate topics vary from punishment issues and dignity, to issues forming a moral and religious education to the child. Also, treatment is studied in isolation from the social environment of the time, as there are references to institutions, individuals and social habits, while criticizing the haves, and in more specific matters, such as religion.

description: Το υψόμετρο αποτελεί έναν σημαντικό παράγοντα που επηρεάζει την ποιότητα των καρπών. Τα ροδάκινα αποτελούν μια από τις σημαντικότερες καλλιέργειες οπωροφόρων δέντρων παγκοσμίως. Η καλλιέργεια τους στην χώρα μας πραγματοποιείται σε διάφορα υψόμετρα, γεγονός που έχει ως συνέπεια την παραγωγή καρπών με ποικίλη διατροφική αξία. Η επίδραση του υψομέτρου στην ποιότητα των ροδακίνων έχει ελάχιστα μελετηθεί τα προηγούμενα χρόνια. Στην παρούσα μεταπτυχιακή διατριβή μελετήθηκε η επίδραση του υψομέτρου σε καρπούς ροδακινιάς της ποικιλίας “June Gold” σε φυσιολογικό, βιοχημικό και μοριακό επίπεδο. Με βάση τα αποτελέσματα των αναλύσεων στους καρπούς που συγκομίστηκαν στο εμπορικό στάδιο, από δυο περιοχές (Βέροια Ημαθίας & Βελβεντό Κοζάνης) με διαφορά υψομέτρου περίπου 424,25 μέτρα διαπιστώθηκαν διαφορές ως προς την συγκέντρωση των αντιοξειδωτικών ουσιών στο εξωκάρπιο (φλοιό) των ροδάκινων. Επιπρόσθετα, το επίχρωμα (%) των καρπών που προέρχονταν από την περιοχή του μεγαλύτερου υψομέτρου ήταν αυξημένο (διπλάσιο) των καρπών που προέρχονταν από την περιοχή του μικρότερου υψομέτρου. Για την πληρέστερη κατανόηση της επίδρασης του υψομέτρου στους καρπούς ροδακινιάς της ποικιλίας “June Gold” πραγματοποιήθηκε πρωτεομική ανάλυση στον φλοιό των καρπών. Με δισδιάστατη ηλεκτροφόρηση σε συνδιασμό με φασματοσκοπία μάζας ταυτοποιήθηκαν 42 πρωτεΐνες οι οποίες διέφεραν εξαιτίας του υψομέτρου. Οι πρωτεΐνες αυτές ανήκουν σε 8 κύριες λειτουργικές κατηγορίες (άμυνας, κύριου ενεργειακού μεταβολισμού κ.λπ.) και ταυτοποιήθηκαν σε 9 διαφορετικά σημεία του κυττάρου (χλωροπλάστη, πυρήνα κ.λπ.).
description: Altitude is important factor that regulate fruit quality. Peach is an important fruit tree crop in Greece that cultivated in regions with different altitudes. However, the impact of altitude on fruit quality was not studied yet. Thus, in this thesis an attempt was made to characterize the effect of altitude on the quality traits of peach fruit (Prunus persica, cv. “June Gold”) at physiological, biochemical and molecular level. It was evidenced that fruits grown in the two district areas in terms of altitude (Veroia Imathias & Velventos Kozanis) showed significant differences in the concentration of antioxidants in the peel tissue. Additionally, red color coverage of the fruits harvest at high altitude was remarkably increased in relation to the fruits from the low altitude. To characterize the effect of altitude on peach fruit biology the proteome of peach peel was analyzed using two-dimensional electrophoresis coupled with mass spectroscopy approach a total amount of 42 proteins were identified in the peel of the peaches that changed in abundance by the altitude, that mainly belong to 8 main functional categories including defense, primary metabolism and protein destination and storage.

description: The mid-infrared spectrum contains rich diagnostics to probe the physical properties of galaxies, among which the pervasive emission features from polycyclic aromatic hydrocarbons (PAHs) offer a promising means of estimating the star formation rate (SFR) relatively immune from dust extinction. This paper investigates the effectiveness of PAH emission as a SFR indicator on sub-kpc scales by studying the Spitzer/IRS mapping-mode observations of the nearby grand-design spiral galaxy M51. We present a new approach of analyzing the spatial elements of the spectral datacube that simultaneously maximizes spatial resolution and spatial coverage, while yielding reliable measurements of the total, integrated $5-20\,μ$m PAH emission. We devise a strategy of extracting robust PAH emission using spectra with only partial spectral coverage, complementing missing spectral regions with properly combined mid-infrared photometry. We find that in M51 the PAH emission correlates tightly with the extinction-corrected far-ultraviolet, near-ultraviolet, and H$α$ emission, from scales$\sim 0.4$ kpc close to the nucleus to 6 kpc out in the disk of the galaxy, indicating that PAH serves as an excellent tracer of SFR over a wide range of galactic environments. But regional differences exist. Close to the active nucleus of M51 the 6.2 $μ$m feature is weaker, and the overall level of PAH emission is suppressed. The spiral arms and the central star-forming region of the galaxy emit stronger 7.7 and 8.6 $μ$m PAH features than the inter-arm regions.

Η παρούσα ερευνητική εργασία αναπτύσσεται σε δύο ενότητες. Η πρώτη, της ανάλυσης και τεκμηρίωσης του ιστορικού κτιρίου, περιλαμβάνει τα ιστορικά στοιχεία, την τυπολογία, την μορφολογία, την παθολογία και τέλος την αξιολόγηση της υφιστάμενης κατάστασης του ιστορικού κελλίου. Η δεύτερη περιέχει τις ενέργειες συντήρησης και αποκατάστασης του, καθώς και τις νέες κατασκευές που σχεδιάζονται στο προς μελέτη ιστορικό περιβάλλον . Πέραν τον επεμβάσεων που αφορούν το ιστορικό κελλί, η εργασία, με τον σχεδιασμό νέων κατασκευών, εστιάζει στο ζήτημα της ένταξης στο Άγιο Όρος. Έτσι αναπτύσσονται ζητήματα και βγαίνουν συμπεράσματα γύρω από τη χρήση, τη δομή, τα υλικά και τη μορφή. Η επαφή με όλο αυτό το ιστορικό κτιριακό απόθεμα, η προσπάθεια για ένα σύγχρονο σχεδιασμό που βασίζεται σε οικοδομική του παρελθόντος, οδήγησαν στην κατανόηση των κατασκευών, της χρήσης του ξύλου και της πέτρας. Σύμφωνα με τον τρόπο που προσεγγίστηκε το θέμα, καταλήγουμε στο ότι η ένταξη νέων κατασκευών στο Άγιον Όρος είναι η ανάγνωση της ταυτότητας της σύνθεσης, σε σχέση με τον ιδιαίτερο τοπιακό της χώρο, αλλά και σε σχέση με την ίδια της την οντότητα, ως δημιούργημα.
description: Τhe subject study of the thesis is the restoration study of the Holy Iviritis Cell of the Holy Ascension Monastery, as well as the integration of new constructions in its historic environment. This research paper elaborates on two sections. The first one is about the analysis and the documentation of the historic building which includes the historical evidence, typology, morphology, pathology and finally the evaluation of the current situation of the cell. The second section elaborates on its maintenance actions and on new constructions that are being designed in the historic environment under study. Apart from the interventions concerning the historic cell, the work and the design of the new structures raises the issue of integration on Mount Athos. Therefore, there are issues and conclusions being derived in terms of use, structure, materials and form. The connection with the historic building stock and the attempt for a modern design based on past construction technique led to the understanding of constructions, the use of wood and stone. According to the way the issue was approached, we come up to the conclusion that the integration of new constructions on Mount Athos is a reading of the synthesis identity in relation to the special landscape, as well as in relation to its entity as a creation itself.
A Quantitative Framework To Assess Communities Resilience at the State Level

description: This research presents an analytical approach to assess the resilience of communities and states based on the Hyogo Framework for Action (HFA). The United Nations (UN) through their advancements in the Disaster Risk Reduction have released multiple international blueprints to help build the resilience of nations and communities, among which we mention the Hyogo Framework for Action and the Sendai Framework. The latter is still under development as the risk bases and the resilience indicators are yet to be defined. For this reason, the work presented here is built upon the more complete HFA framework. A number of weighted indicators taken from HFA are used to compute resilience. Those indicators, however, do not affect the resilience index equally. This discrepancy necessitates the need to weigh the indicators on the basis of their individual contribution towards resilience. In order to achieve this, we have used the Dependence Tree Analysis (DTA). This method allows identifying the dependencies between the HFA indicators and the resilience index and evaluate in unbiased way the weight factors of the different indicators. The research is also proposing an analytic formulation to assess a new index, Bounce Back index (BBI), which combines both community’s Exposure, Hazard, and Resilience together. To illustrate the methodology in full details, a case study composed of 37 countries is presented in this research, where the Resilience and the Bounce Back indexes of each country are evaluated.

Computational identification and characterization of RNA-binding proteins in Salmonella

description: RNA-binding proteins (RBPs) have been widely studied in eukaryotes where they post-transcriptionally regulate many events including RNA transport, translation and stability. By contrast, our knowledge of the number and potential diversity of RBPs in bacteria is very incomplete.

Several studies have been carried out using experimental techniques such as cross-linking and immunoprecipitation, which have enabled the characterization of RNA-binding motifs and their regulatory mechanisms in RBPs. Unfortunately, large-scale screening for RBPs by those methods is expensive and time consuming; therefore such studies have been performed for a limited selection of organisms. Recently, computational approaches have been developed for the identification and characterization of protein-RNA interactions, but these methods have not been adapted for proteome-wide identification of RBPs.

Here, we aim to develop an efficient and cost-effective computational method for a systematic proteome-wide screening of RBPs in bacteria. We have focused on identifying functional domains in proteins that may interact with RNA and predict their regulatory roles and mechanisms. For this purpose, we assembled sequence-based approaches for the functional characterization of the proteins in an automated pipeline called APRICOT (Analysing Protein RNA Interactions by Computational Techniques). Using this pipeline, a proteome-wide prediction of RBPs was carried out in Salmonella typhimurium and selected candidates are being tested by sequencing of immunoprecipitated RNA. The experimental results are recursively used to improve the computational RBP identification.

In future, APRICOT will be extended to assess the potential of a protein to interact to other molecular components in a variety of biological system.
Lepton flavor violating signals of a little Higgs model at the high energy linear $e^{+}e^{-}$ colliders

description: Littlest Higgs $(LH)$ model predicts the existence of the doubly charged scalars $Φ^{\pm\pm}$, which generally have large flavor changing couplings to leptons. We calculate the contributions of $Φ^{\pm\pm}$ to the lepton flavor violating $(LFV)$ processes $l_{i}\to l_{j}γ$ and $l_{i}\to l_{j}l_{k}l_{k}$, and compare our numerical results with the current experimental upper limits on these processes. We find that some of these processes can give severe constraints on the coupling constant $Y_{ij}$ and the mass parameter $M_Φ$. Taking into account the constraints on these free parameters, we further discuss the possible lepton flavor violating signals of $Φ^{\pm\pm}$ at the high energy linear $e^{+}e^{-}$ collider $(ILC)$ experiments. Our numerical results show that the possible signals of $Φ^{\pm\pm}$ might be detected via the subprocesses $e^{\pm}e^{\pm}\to l^{\pm}l^{\pm}$ in the future $ILC$ experiments.

description: In this paper we present calculations on the electronic band structure of a two-dimensional lateral superlattice subject to a perpendicular magnetic field by employing a projection operator technique based on the ray-group of magnetotranslation operators. We construct a new basis of appropriately symmetrized Bloch-like wavefunctions as linear combination of well-localized magnetic-Wannier functions. The magnetic field was consistently included in the Wannier functions defined in terms of free-electron eigenfunctions in the presence of external magnetic field in the symmetric gauge. Using the above basis, we calculate the magnetic energy spectrum of electrons in a lateral superlattice with bi-directional weak electrostatic modulation. Both a square lattice and a triangular one are considered as special cases. Our approach based on group theory handles the cases of integer and rational magnetic fluxes in a uniform way and the provided basis could be convenient for further both analytic and numerical calculations.

Η συγκριτική ανάλυση των δύο κειμένων θα βοηθήσει στο να βρεθούν και να κατανοηθούν οι διαφορές και οι ομοιότητες ανάμεσα στις θέσεις των δύο συγγραφέων ώστε να προσδιοριστούν οι ηθικές διαστάσεις της πολιτικής εξουσίας.
description: In this paper we will speak of the relation of morality to political power through the analysis of two projects which have the same title: 'The Hegemon' and come from two writers as diverse: the Patriarch Photios (9th century) and Niccolο Machiavelli (16th century). The involvement of both authors on the same subject, which are time, local and ideologically between them, causing a comparative investigation of ethical dimensions governing hegemony, namely the political power. The purpose of this work is the analysis and interpretation of these two projects and their comparison to understand the ethical principles in the way power is exercised and by extension the virtues of the ruler. The comparative analysis of the two texts will help to find and understand the differences and similarities between the two authors jobs to identify the ethical dimensions of political power.

description: Magnetic fields are an important but largely unknown ingredient of planetary nebulae. They have been detected in oxygen-rich AGB and post-AGB stars, and may play a role in the shaping of their nebulae. Here we present SCUBA sub-millimeter polarimetric observations of four bipolar planetary nebulae and post-AGB stars, including two oxygen-rich and two carbon-rich nebulae, to determine the geometry of the magnetic field by dust alignment. Three of the four sources (NGC 7027, NGC 6537 and NGC 6302) present a well-defined toroidal magnetic field oriented along their equatorial torus or disk. NGC 6302 may also show field lines along the bipolar outflow. CRL 2688 shows a complex field structure, where part of the field aligns with the torus, whilst an other part approximately aligns with the polar outflow. It also presents marked asymmetries in its magnetic structure. NGC 7027 shows evidence for a disorganized field in the south-west corner, where the SCUBA shows an indication for an outflow.

description: Predicting the final ischaemic stroke lesion provides crucial information regarding the volume of salvageable hypoperfused tissue, which helps physicians in the difficult decision-making process of treatment planning and intervention. Treatment selection is influenced by clinical diagnosis, which requires delineating the stroke lesion, as well as characterising cerebral blood flow dynamics using neuroimaging acquisitions. Nonetheless, predicting the final stroke lesion is an intricate task, due to the variability in lesion size, shape, location and the underlying cerebral haemodynamic processes that occur after the ischaemic stroke takes place. Moreover, since elapsed time between stroke and treatment is related to the loss of brain tissue, assessing and predicting the final stroke lesion needs to be performed in a short period of time, which makes the task even more complex. Therefore, there is a need for automatic methods that predict the final stroke lesion and support physicians in the treatment decision process. We propose a fully automatic deep learning method based on unsupervised and supervised learning to predict the final stroke lesion after 90 days. Our aim is to predict the final stroke lesion location and extent, taking into account the underlying cerebral blood flow dynamics that can influence the prediction. To achieve this, we propose a two-branch Restricted Boltzmann Machine, which provides specialized data-driven features from different sets of standard parametric Magnetic Resonance Imaging maps. These data-driven feature maps are then combined with the parametric Magnetic Resonance Imaging maps, and fed to a Convolutional and Recurrent Neural Network architecture. We evaluated our proposal on the publicly available ISLES 2017 testing dataset, reaching a Dice score of 0.38, Hausdorff Distance of 29.21 mm, and Average Symmetric Surface Distance of 5.52 mm.

description: A study of cutting-edge theoretical modelling of the dynamics of astrophysical plasma  was done in a variety of astrophysical scenarios, such as under quantum mechanical effect, in which particle number density, pressure and magnetic field strengths needed for consideration of quantum mechanical effect in a magnetized plasma were calculated; under relativistic effects, where the factor of increase in the fluid and magnetic pressure of a magnetized plasma due to the relativistic effects were calculated and under the effect of neutrino oscillations, where the magnetic field strengths in neutrino MHD fluids were calculated.
The dead and the living : burial mounds & cairns and the development of social classes in the Gulf of Georgia region
Creators: name: Thom, Brian David
Publisher: name: University of British Columbia
Year: 2009

description: This thesis provides a model for understanding how social classes arose in the Gulf of Georgia area. This model distinguishes how social status in rank and a class societies are manifested and maintained in non-state, kin-based societies, drawing mainly from ethnographic descriptions. The relationship between the living and the dead for making status claims in both rank and class societies makes the archaeological study of mortuary ritual important for investigating these relationships. I propose that burial mounds and cairns, which were prominent in the region from 1500 to 1000 years ago, reflect a time when status differentiation was defined mainly through social rank. Following this period, when all forms of below-ground burials cease and above-ground graves become the dominant form of mortuary practice, I propose that the historically recorded pattern of social class emerged. Archaeological investigations of the burial mounds and cairns at the Scowlitz site have provided the first fully reported instances of mound and cairn burials in this region. Using less well reported data from over 150 additional burial mounds and cairns reported from other sites in the region, evidence for the nature of status differentiation sought out. Patterns in the burial record are investigated through discussing variation within classes of burials, demography and deposition, spatial patterning, grave goods, and temporal variation. These patterns and changes are then discussed within the context of the larger culture history of the region, suggesting that the late Marpole or Garrison sub-phase may be defined as ending around 1000 BP with the cessation of below-ground burial practices. The general patterns observed in mound and cairn burials and the changes in mortuary ritual subsequent to their being built generally support the idea of a shift from a rank to a class society. The thesis provides a basis for further investigation of questions of social status and inequality in the Gulf of Georgia region.

description: We present the activity and kinematics of a representative volume-limited (20 pc) sample of 152 late-M and L dwarfs (M7--L8) photometrically selected from the Two Micron All-Sky Survey (2MASS). Using new proper motion measurements and spectrophotometric distance estimates, we calculate tangential velocities. The sample has a mean tangential velocity of = 31.5 km/s, a velocity dispersion of sigma_tan = 20.7 km/s, and a maximum tangential velocity of V_tan = 138.8 km/s. These kinematic results are in excellent agreement with previous studies of ultracool dwarfs in the local solar neighborhood. H_alpha emission, an indicator of chromospheric activity, was detected in 63 of 81 late-M dwarfs and 16 of 69 L dwarfs examined. We find a lack of correlation between activity strength, measured by log(F_H_alpha/F_bol), and V_tan, though velocity distributions suggest that the active dwarfs in our sample are slightly younger than the inactive dwarfs. Consistent with previous studies of activity in ultracool dwarfs, we find that the fraction of H$α$ emitting objects per spectral type peaks at spectral type M7 and declines through mid-L dwarfs. Activity strength is similarly correlated with spectral type for spectral types later than M7. Eleven dwarfs out of 150 show evidence of variability, ranging from small fluctuations to large flare events. We estimate a flare cycle of ~5% for late-M dwarfs and ~2% for L dwarfs. Observations of strong, variable activity on the L1 dwarf 2MASS J10224821+5825453 and an amazing flare event on the the M7 dwarf 2MASS J1028404$-$143843 are discussed.

description: We have measured photoemission spectra of two kinds of TiO$_2$-capped VO$_2$ thin films, namely, that with rutile-type TiO$_2$ (r-TiO$_2$/VO$_2$) and that with amorphous TiO$_2$ (a-TiO$_2$/VO$_2$) capping layers. Below the Metal-insulator transition temperature of the VO$_2$ thin films, $\sim 300$ K, metallic states were not observed for the interfaces with TiO$_2$, in contrast with the interfaces between the band insulator SrTiO$_3$ and the Mott insulator LaTiO$_3$ in spite of the fact that both TiO$_2$ and SrTiO$_3$ are band insulators with $d^0$ electronic configurations and both VO$_2$ and LaTiO$_3$ are Mott insulators with $d^1$ electronic configurations. We discuss possible origins of this difference and suggest the importance of the polarity discontinuity of the interfaces. Stronger incoherent part was observed in r-TiO$_2$/VO$_2$ than in a-TiO$_2$/VO$_2$, suggesting Ti-V atomic diffusion due to the higher deposition temperature for r-TiO$_2$/VO$_2$.

description: We consider N=2 supersymmetric quantum electrodynamics (SQED) with 2 flavors, the Fayet--Iliopoulos parameter, and a mass term $β$ which breaks the extended supersymmetry down to N=1. The bulk theory has two vacua; at $β=0$ the BPS-saturated domain wall interpolating between them has a moduli space parameterized by a U(1) phase $σ$ which can be promoted to a scalar field in the effective low-energy theory on the wall world-volume. At small nonvanishing $β$ this field gets a sine-Gordon potential. As a result, only two discrete degenerate BPS domain walls survive. We find an explicit solitonic solution for domain lines -- string-like objects living on the surface of the domain wall which separate wall I from wall II. The domain line is seen as a BPS kink in the world-volume effective theory. We expect that the wall with the domain line on it saturates both the $\{1,0\}$ and the $\{{1/2},{1/2}\}$b central charges of the bulk theory. The domain line carries the magnetic flux which is exactly 1/2 of the flux carried by the flux tube living in the bulk on each side of the wall. Thus, the domain lines on the wall confine charges living on the wall, resembling Polyakov's three-dimensional confinement.

description: This volume covers Leg 70 of the cruises of the Drilling Vessel Glomar Challenger. The major objectives of the first part of Leg 70 were to collect data and sediment representative of the hydrothermal mounds and ridges located about 20 km south of the Galapagos spreading axis. Undisturbed, continuous stratigraphic sequences of sediments and basement rocks from the mounds and from off-mound areas were required to answer the following specific questions: 1) How does the stratigraphy on a mound compare to that off a mound? Similarly, how do the pore water chemistry, physical and paleomagnetic properties, mineralogy, and paleontology of the sediments compare between these two areas? 2) How does the heat flow measured over the entire sediment column compare to that measured in the upper few meters of sediment? 3) Do the two sub-bottom reflectors correspond to lithologic boundaries or to physical property changes in sediments? 4) How variable is sediment stratigraphy of mounds within the same area? 5) Is there a difference between the alteration of basement rock directly beneath the mounds and away from them? 6) Are the chemistry, mineralogy, and physical and magnetic properties of the basement rock affected by the hydrothermal processes which produced the mounds sediments? 7) Are magnetic properties of the basement rocks compatible with the regional magnetic anomaly? 8) Over what period of time were the mounds formed, and are they presently active? The D/V Glomar Challenger departed Balboa, Panama on 11 November 1979, heading to the Galapagos hydrothermal mounds area to drill 5 sites (506 – 510). The cruise ended in Callao, Peru in December 1979.

description: Experimental results for the evolution of the probability distribution function (PDF) of a scalar mixed by a turbulence flow in a channel are presented. The sequence of PDF from an initial skewed distribution to a sharp Gaussian is found to be non universal. The route toward homogeneization depends on the ratio between the cross sections of the dye injector and the channel. In link with this observation, advantages, shortcomings and applicability of models for the PDF evolution based on a self-convolution mechanisms are discussed.

description: Most of the visible matter in the Universe is in a plasma state, or more specifically is composed of ionized or partially ionized gas permeated by magnetic fields. Thanks to recent advances on the theory and detection of cosmic magnetic fields there has been a worldwide growing interest in the study of their role on the formation of astrophysical sources and the structuring of the Universe. In this lecture, I will briefly review the importance of the cosmic magnetic fields both from a theoretical and from an observational perspective, particularly focusing on stellar and compact objects, the interstellar medium and star formation regions, and on galaxies, clusters of galaxies, and the primordial Universe.

description: Use of standards-based workflows is still somewhat unusual by high-performance computing users. In this paper we describe the experience of using the Common Workflow Language (CWL) standards to describe the execution, in parallel, of MPI-parallelised applications. In particular, we motivate and describe the simple extension to the specification which was required, as well as our implementation of this within the CWL reference runner. We discuss some of the unexpected benefits, such as simple use of HPC-oriented performance measurement tools, and CWL software requirements interfacing with HPC module systems. We close with a request for comment from the community on how these features could be adopted within versions of the CWL standards.
