description: Nickel sulfide formation from nickel-containing steel residuals in the glass batch has been assumed for quite some time. Melting trials were carried out with a soda-lime-silica glass batch containing steel particles with 20 % nickel. By this the above assumption was shown to be true and the exact cascade of the reaction of the metals with the sulfate of the glass melt could be pointed out. Five steps can be distinguished: sweating out the less noble elements (chromium, manganese, carbon); formation of a mixed iron nickel sulfide phase in equilibrium with the remaining iron nickel alloy; enrichment of nickel in the alloy and the sulfide phase, until complete elimination of iron; sulfidation of the remaining pure nickel and formation of a nickel-rich sulfide; oxidation to NiS. The reaction cascade found experimentally is confirmed by the authors' own thermodynamic calculations. Literature data show that nickel sulfides containing more sulfur than the 1:1 composition are not stable in the glass melt and decompose in a small "explosion". The exact composition of an NiS stone found in glass depends on its individual temperature/time history. It consists mainly of (Ni,Fe)S, which may transform to millerite. If the former sulfide melt still contains a nickel excess, the crystalline stone may also contain minor parts of other NiySx phases such as Ni9S8 or Ni7S6.

description: An alternative Monte Carlo estimator for the one-body density rho(r) is presented. This estimator has a simple form and can be readily used in any type of Monte Carlo simulation. Comparisons with the usual regularization of the delta-function on a grid show that the statistical errors are greatly reduced. Furthermore, our expression allows accurate calculations of the density at any point in space, even in the regions never visited during the Monte Carlo simulation. The method is illustrated with the computation of accurate Variational Monte Carlo electronic densities for the Helium atom (1D curve) and for the water dimer (3D grid containing up to 51x51x51=132651 points).

description: When two indistinguishable single photons are fed into the two input ports of a beam splitter, the photons will coalesce and leave together from the same output port. This is a quantum interference effect, which occurs because the two possible paths where the photons leave in different output ports interfere destructively. This effect was first observed in parametric downconversion by Hong, Ou and Mandel, and then with single photons produced one after the other by the same quantum emitter. With the recent development of quantum information, a lot of attention has been devoted to this coalescence effect as a resource for quantum data processing using linear optics techniques. To ensure the scalability of schemes based on these ideas, it is crucial that indistinguishable photons are emitted by a collection of synchronized, but otherwise independent sources. In this paper, we demonstrate the quantum interference of two single photons emitted by two independently trapped single atoms, bridging the gap towards the simultaneous emission of many indistinguishable single photons by different emitters. Our data analysis shows that the coalescence observed is mostly limited by the wavefront matching of the light emitted by the two atoms, and to a lesser extent by the motion of each atom in its own trap.

description: The Rivlin-Ericksen model is one of the oldest models in fluid dynamics to describe non-Newtonian properties. The model comes with two independent transports at second order. In this paper, we study the relativistic origin of the Rivlin-Ericksen fluid. Starting from a relativistic Weyl invariant uncharged fluid in $3+1$ dimensions, we reduce it over light-cone directions and obtain a generic non-relativistic uncharged fluid in one lower dimension with all possible second order terms in the constitutive relations. We observe that the Rivlin-Ericksen fluid is a subclass of our generalised non-relativistic system. We also compute the holographic values of all the non-relativistic second order transports and find that three of them satisfy a universal constraint relation.

Low-emissive coatings on the outer surface of heat-insulating glasses - a challenge to the flat glass industry

description: The influence of low-emissive coatings on the outer surface of window glazings is reported.They reduce the heat radiation exchange with the open sky respectively the surroundings. However, they are effective and without disadvantages only on the outdoor surface of heat-insulating glasses. Here they diminish the risk of dewing on this surface and the heat loss through the window is not only decreased but it becomes also independent of the inclination of the glazing in the facade. The low-emissivity of coatings is camouflaged by wetting during rain, however, because in this case the sky is overcast, the heat loss is only insignificantly increased. It is known that the covering of dirt by weathering significantly decrease solar transmittance for all kinds of glazings. But surprisingly it has shown that these coverings only insignificantly influence the emissivity of coatings beneath. This proves that the function of heat-insulating glasses with low-emissive coatings on the outdoor surfaces is not impaired by weathering if the coatings have sufficient ageing resistance to environmental attacks.Today, there are low-emissive coatings on the base of SnO2 on the market with high solar transmittance developed forposition 3 of double heat-insulating glasses as well as coatings with reduced solar transmittance for position 2 of solar control glasses. Because the chemical and abrasive resistance of both types of coatings is better than that of untreated float glass, they can also be applied on outdoor surfaces. With these coatings on position 1 a new generation of heat-insulating and solar control glasses with improved functions can be created. In combination with the developing of coatings more advantageous than those on the base of SnO2 this may be a challenge to the flat glass industry in the future.

description: Concentrated sodium silicate solutions with a SiO2:Na2O molar ratio of 3.3 and a SiO2 content of 27 wt% were dried at temperatures between 30 and 100 °C to residual water contents between 11 and 45 wt%. The materials are brittle, transparent and X-ray amorphous. Their structure is discussed, with the conclusion that it is vitreous. The materials were investigated by thermal analysis techniques (e.g. differential scanning calorimetry in open and closed crucibles, thermogravimetry, hot stage microscopy), optical and electron microscopy, and X-ray diffraction. Up to six thermal events detected by thermal analysis are discussed. Two of these thermal events were analysed with respect to their heat rate dependence and are discussed with respect to structural transitions (glass to gel and gel to sol). Other events are also discussed, such as the temperatures of foam formation during heating and the boiling temperatures of the investigated samples.

Στην έρευνα συμμετείχαν 360 παιδιά (194 αγόρια και 166 κορίτσια), ηλικίας 11-12 ετών, από δέκα σχολεία, χωρισμένα σε δύο ομάδες: μία ομάδα με έμφαση στον προσανατολισμό στο «έργο» και μία ομάδα με έμφαση στον προσανατολισμό στο «εγώ». Σχεδιάστηκαν και διδάχθηκαν τέσσερα μαθήματα φυσικής αγωγής. Η έρευνα πραγματοποιήθηκε με την βοήθεια ερωτηματολογίων και δύο κινητικών τεστ στην πετοσφαίριση. Από την στατιστική ανάλυση των δεδομένων διαπιστώθηκε ότι τα κορίτσια είναι περισσότερο εσωτερικά παρακινημένα και παρουσίασαν αυξημένα σκορ στους στόχους της κοινωνικής αποδοχής και της προσωπικής βελτίωσης. Σχετικά με το στόχο της απόδοσης οι μαθητές/τριες της ομάδας που διδάχθηκαν μαθήματα με έμφαση στον προσανατολισμό στο "εγώ" παρουσίασαν υψηλότερα σκορ σε σύγκριση με την ομάδα "έργου". Τα ευρήματα της παρούσας έρευνας πιστοποιούν ότι ένα μάθημα φυσικής αγωγής δομημένο με στόχους (είτε μάθησης είτε επίδοσης) δίνει ουσιαστικά κίνητρο στην προσπάθεια των μαθητών, επηρεάζει θετικά την πρόθεση για συμμετοχή και βελτιώνει προοδευτικά την απόδοση.
description: The purpose of this study was to explore the effect that the structure of aim has on internal motivation, achievement goals, the climate of motivation and the performance of final form primary school students. The survey took a sample of 360 children (194 boys and 166 girls) aged 11-12, from ten schools divided into two groups. The first experimental was the task involving emphasis group and the other with the ego involving emphasis group. Four P.E. sessions were planned and taught. The research was carried out through questionnaires and motor tests in volleyball. From the statistical analysis of data was found that girls are more internally motivated and scored higher on targets of social acceptance and personal improvement. Regarding the purpose of performance those students who were taught lessons of orientation with emphasis on the "ego" demonstrated higher levels of achievement compared with the "task" group. The findings of this research confirm that a P.E. lesson that sets targets either learning or performance, contributes significantly to students' motivation revives their interest in participation and gradually enhances their performance.

description: We report on spin Hall magnetoresistance (SMR) and spin Seebeck effect (SSE) in single crystal of the rare-earth antiferromagnet DyFeO$_{3}$ with a thin Pt film contact. The angular shape and symmetry of the SMR at elevated temperatures reflect the antiferromagnetic order of the Fe$^{3+}$ moments as governed by the Zeeman energy, the magnetocrystalline anisotropy and the Dzyaloshinskii-Moriya interaction. We interpret the observed linear dependence of the signal on the magnetic field strength as evidence for field-induced order of the Dy$^{3+}$ moments up to room temperature. At and below the Morin temperature of 50$\,$K, the SMR monitors the spin-reorientation phase transition of Fe$^{3+}$ spins. Below 23$\,$K, additional features emerge that persist below 4$\,$K, the ordering temperature of the Dy$^{3+}$ magnetic sublattice. We conclude that the combination of SMR and SSE is a simple and efficient tool to study spin reorientation phase transitions and sublattice magnetizations.

description: This paper is the second part of a parametric study of the flow and thermal structures in glass melting furnaces with a throat. The effects of the following parameters are discussed: a) the batch velocity, b) the melting temperature, c) the submerged depth of the batch, d) the wall heat losses, and e) the thickness of glass melt containing gas bubbles under the batch. The study indicates that the partially submerged batch and heat losses through the refractories have a strong impact on both the longitudinal and spanwise flow patterns of the molten glass. These physical phenomena must be accounted for if one wants to realistically simulate the natural convection circulation of the molten glass in the bath.

description: The weathering of K-glass has been studied by measuring transmission and reflection in the visible (VIS), near infrared (NIR) and infrared (IR) wavelength ranges, by chemical depth profiling with secondary neutral mass spectrometry (SNMS) and by atomic force microscopy (AFM) imaging. K-glass is a commercial tin oxide coated glass with low IR emissivity. The SnO2:F-coated side has been exposed to atmospheric conditions for up to 32 weeks and for up to two years. It could be shown that the optical properties are only affected in the VIS range, but the visible contamination does not influence the high IR reflection. This means that the heat-insulating properties of window glazings with the K-glass coating on the surface do not degrade under atmospheric conditions. Chemical depth profiles did not reveal major changes, except for an increase in the signals of minor elements on the surface, namely sodium, carbon and silicon. AFM showed that after 32 weeks the deep valleys of the rather rough crystalline SnO2:F are partially filled up. The high transmission of new K-glass can be regained since contamination or corrosion products can be removed by washing. The coating itself is chemically stable.

description: On May 21, 2019 Advanced LIGO and Advanced Virgo detectors observed a gravitational-wave transient GW190521, the heaviest binary black-hole merger detected to date with the remnant mass of 142$\,$M$_\odot$ that was published recently. This observation is the first strong evidence for the existence of intermediate-mass black holes. The significance of this observation was determined by the coherent WaveBurst (cWB) - search algorithm, which identified GW190521 with minimal assumptions on its source model. In this paper, we demonstrate the capabilities of cWB to detect binary black holes without use of the signal templates, describe the details of the GW190521 detection and establish the consistency of the model-agnostic reconstruction of GW190521 by cWB with the theoretical waveform model of a binary black hole.

description: High-throughput molecular profiling technologies have produced high-dimensional multi-omics data, enabling systematic understanding of living systems at the genome scale. Studying molecular interactions across different data types helps reveal signal transduction mechanisms across different classes of molecules. In this paper, we develop a novel Bayesian representation learning method that infers the relational interactions across multi-omics data types. Our method, Bayesian Relational Learning (BayReL) for multi-omics data integration, takes advantage of a priori known relationships among the same class of molecules, modeled as a graph at each corresponding view, to learn view-specific latent variables as well as a multi-partite graph that encodes the interactions across views. Our experiments on several real-world datasets demonstrate enhanced performance of BayReL in inferring meaningful interactions compared to existing baselines.

description: Powder technology and sintering were used to fabricate glass-ceramic matrix composites from Latvian industrial wastes and alumina platelets reinforcement. The optimization of the sintering behaviour of glass-ceramic compositions containing clay and alumina platelets was carried out. Highly crystalline and dense products (> 90 % theoretical density) were fabricated by sintering at temperatures in the range 1040 to 1060 °C, depending on composition. Addition of waste glass to influence the sintering temperature and sintering interval was also investigated. Composites showed higher fracture strength (up to 97 MPa) and hardness than unreinforced glass-ceramics. The "best" composition in terms of density and mechanical properties contained 20 wt% alumina platelets. The matrix exhibited a microstructure composed mainly of elongated crystals of pyroxene type in a residual glassy matrix. These composites are candidates for applications as building materials, such as floor and wall tiles, and for manufacturing machine elements and parts.

description: In this study five series of glasses belonging to the general formula xAl2O3 ∙ (1 - x - y)PbO ∙ yP2O5 were prepared. In each of these series y was unchanged and the amount of alumina that could be added yielding a clear glass was found to depend on its value. The structure and aqueous resistance of the prepared glasses were investigated. The initial substitutions of AI2O3 for PbO considerably improve aqueous resistance of the glasses studied, whereas the subsequent substitutions have a much lesser effect. In turn, the influence of the initial substitutions on the aqueous resistance of the glasses is gradually diminished as the PbO contents of the base glasses (i.e., Al2O3-free glasses) are increased. Structurally, the dominance level of the Al(PO)4 moities was found to rise as the limiting composition was approached in each of the studied series. Moreover, the capability of these moieties to enhance glass crystallization was verified. In addition, PbO was found to enhance the formation of Q1-end groups in the glass structures. Glasses deviated from the uniform dissolution mechanism typical of phosphate glasses are classified into two subgroups according to the molar percentage value of the P2O5 component in their leached solution, as determined by the ICP measurements. The structural origins for these deviations were discussed.

Αν L(M) είναι η γλώσσα που αναγνωρίζεται από έναν μη-πλήρη ασαφή αναγνωριστή Μ, δείχνουμε ότι υπάρχει μία πλήρωση Μc του Μ τέτοια, ώστε: L(M)=L(M)
description: In the first chapter, fuzzy language recognizability via finite monοids (called m-recognizability) is examined. Fuzzy languages computed by (max, min)-automata, (max, ) -automata and (max, ) - automata are m-recognizable. The syntactic monoid associated to each m-recognizable language can be effectively constructed.In the second chapter, we show that a fuzzy language is recognized by a finite monoid iff has finitely many right derivatives, iff it has finitely many left derivatives. Finally we show that the behaviors of Lukasiewicz automata have the above properties. In the third chapter, we present a type of algebra, called the max-product algebra, in order to examine the properties of max-product machines. A formulation of max-product grammars is given in this section and then an alternative formulation of max-product grammars is given. This alternative formulation is motivated by the fact that max-product grammars be viewed as a model of fuzzy grammars.In the fourth chapter, we define and examine the concept of a fuzzy recognizer. If L(M) is the language recognized by an incomplete fuzzy recognizer M, we show that there is a completion Mc of M such that (M)=L(M)

description: Η αρνητική έκβαση του κρητικού πολέμου και η παράδοση του Χάνδακα το 1669 είχαν σαν αποτέλεσμα οι Μανιάτες, που συνεργάστηκαν με τους Βενετούς και τους Κρητικούς εναντίον των Τούρκων, να εγκαταλείψουν μαζικά τη Μάνη. Οι περισσότεροι με αρχηγούς την οικογένεια των Στεφανόπουλων κατέφυγαν στην Κορσική, αφού πρώτα υπέγραψαν συμφωνία με τη Δημοκρατία της Γένοβας. Εκεί εγκαταστάθηκαν διαδοχικά στην Παόμια, στο Αιάκειο και μετά την προσάρτηση του νησιού στη Γαλλία, στο Καργκέζε. Οι Μανιάτες διαβίωσαν και ευημέρησαν στην Κορσική για τρεις σχεδόν αιώνες (έως τις αρχές του 20ου αιώνα) διατηρώντας την ελληνικότητά τους χάρη στην κοινή γλώσσα, τη θρησκεία, τα ήθη, τα έθιμα και τις συνήθειές τους που τους ξεχώριζαν από τους Κορσικανούς και παρά την πίεση που τους ασκήθηκε από την Καθολική Εκκλησία.
description: The negative outcome of the Cretan war and the surrender of Chandakas to the Turks in 1669 resulted in the massive abandonment of Mani by the local Maniates, who had cooperated with the Venicians and Cretans against the Turks. Most of them having the Stefanopoulow family as leaders went to Corsica after signing an agreement with the Democracy of Genova. There, they settled successively in Paomia, in Aiakeio and in Cargese, after the annexation of the island to France. The Maniates lived and prospered in Corsica for almost 3 centuries (until the beginning of the 20th century) maintaining their Greek identity thanks to their common language, religion, traditions, customs and habits which distinguished them from the Corsicans, despite the pressure forced of them by the Catholic Church.

description: The set of orbits of $GL(V)$ in $Fl(V)\times Fl(V)\times V$ is finite, and is parametrized by the set of certain decorated permutations in a work of Solomon. We describe a Mirabolic RSK correspondence (bijective) between this set of decorated permutations and the set of triples: a pair of standard Young tableaux, and an extra partition. It gives rise to a partition of the set of orbits into combinatorial cells. We prove that the same partition is given by the type of a general conormal vector to an orbit. We conjecture that the same partition is given by the bimodule Kazhdan-Lusztig cells in the bimodule over the Iwahori-Hecke algebra of $GL(V)$ arising from $Fl(V)\times Fl(V)\times V$. We also give conjectural applications to the classification of unipotent mirabolic character sheaves on $GL(V)\times V$.

The impact of mood on the endorsement of rumination: an exploration of the association between cognitive biases and behaviour
Creators: name: Pidcock, Madeleine Marie
Publisher: name: The Australian National University
Year: 2015

description: Reliable and robust methods of assessment are crucial to best practise within research and clinical settings. Although there are a number of benefits associated with the use of self-report questionnaires there is cause to examine how accurately they measure the frequency and content of mental processes. In particular, little attention has been paid to the potential influence of mood to effect endorsement behaviour. The existence of mood related variation in response styles would represent a major threat to the correct interpretation of self-report data. In clinical settings this threat is further increased due to samples of respondents who are expected to experience variations in mood across the course of therapy and relevant measurement points (e.g. pre-post treatment outcome measures). This dissertation sought to assess how mood may influence the endorsement of ruminative behaviours. The choice to examine rumination was threefold, rumination has developed as a key construct in understanding cognitive vulnerabilities to depression, it is solely assessed via self-report methodologies, and concerns have been raised that existing questionnaires are overly negative in tone. This is of particular significance given that there is a large body of literature demonstrating that depression is characterised by cognitive biases for negatively valenced stimuli. Such biases have been demonstrated in attention, memory, and interpretation -cognitive processes that are intrinsic to endorsement behaviour. If negative affect influences endorsement of ruminative behaviours, the aforementioned cognitive biases may play a role. This was explored over five studies. Results demonstrated that respondents are sensitive to question valence, and that subtle changes in wording can inflate item negativity. Furthermore, results indicated that experimentally induced negative mood increased perception of item negativity and endorsement of ruminative items. The final two studies highlight possible options for quantifying and minimising the effects of mood related changes in endorsement via the development and validation of a novel measure for endorsement bias, and support for the incorporation of informant-reports in the assessment process.

description: This paper is dedicated to Mike Duff on the occasion of his 70th birthday. I discuss some issues of M-theory/string theory/supergravity closely related to Mike's interests. I describe a relation between STU black hole entropy, Cayley hyperdeterminant, Bhargava cube and a 3-qubit Alice, Bob, Charlie triality symmetry. I shortly describe my recent work with Gunaydin, Linde, Yamada on M-theory cosmology, inspired by the work of Duff with Ferrara and Borsten, Levay, Marrani et al. Here we have 7-qubits, a party including Alice, Bob, Charlie, Daisy, Emma, Fred, George. Octonions and Hamming error correcting codes are at the base of these models. They lead to 7 benchmark targets of future CMB missions looking for primordial gravitational wave from inflation. I also show puzzling relations between the fermion mass eigenvalues in these cosmological models, exceptional Jordan eigenvalue problem, and black hole entropy. The symmetry of our cosmological models is illustrated by beautiful pictures of a Coxeter projection of the root system of E7.

description: A selection of glass samples from the stained glass windows of León Cathedral (Spain) dating from Medieval and Renaissance times has been chemically characterized. The techniques used for this characterization were X-ray diffraction, inductively coupled plasma. X-ray fluorescence and flame photometry. The analyses indicate that the samples are potash-lime glass, with the Medieval glass having a low alumina concentration. This fact has given rise to its deterioration throughout history due to environmental conditions.

Fibre reinforced concrete in shear and flexure
Creators: name: Henley, Julien
Publisher: name: University of British Columbia
Year: 2009

description: An experimental investigation into the effect of steel fibres on the shear strength of concrete beams and slabs containing no transverse reinforcement is presented. Eight slab elements were tested in the UBC Element Tester and eight beams were tested under third point loading. A number of combinations of concrete strength and fibre volumes were considered in the experimental program. The concrete strength was varied from 25 MPa to 95 MPa while the fibre content ranged from 0% to 1.5% by volume. The beams showed an increase in shear strength of up to 80 % when 1.5 % by volume of steel fibres were added to the concrete. Apart from considering the ultimate shear strength of the slabs and beams, the effect of steel fibres on crack widths and modes of crack opening was also considered. A method is presented to include the effect of steel fibres in predicting the flexural strength of steel fibre reinforced concrete sections. Previous results on the pull-out strength of individual fibres were used to define the tensile response of fibre reinforced concrete at a crack. With this proposed stress-strain relationship it is possible to predict the flexural response using a traditional strain compatibility based procedure. A tensile stress block is also derived to simplify flexural predictions. These methods are then compared to experimental results and show favourable agreement. Some possible additions to the Modified Compression Field Theory (MCFT) are suggested to account for the increase in shear strength due to steel fibres. To include the effect of steel fibres in a rationally based method for the shear strength of members containing no transverse reinforcement, the following areas are considered: the average post-cracking tensile response of concrete, the ability of a crack to transmit shear force by aggregate interlock and the crack spacing. The theoretical predictions are compared to the experimental results and some additional experimental work and show promise.

Population Boundaries for Galactic White Dwarf Binaries in LISA's Amplitude-Frequency Domain

Subjects: subject: Astrophysics (astro-ph)

description: Detached, inspiraling and semi-detached, mass-transferring double white dwarf (DWD) binary systems are both expected to be important sources for the proposed space-based gravitational-wave detector, LISA. The mass-radius relationship of individual white dwarf stars in combination with the constraints imposed by Roche geometries permit us to identify population boundaries for DWD systems in LISA's ``absolute'' amplitude-frequency diagram. With five key population boundaries in place, we are able to identify four principal population sub-domains, including one sub-domain that identifies where progenitors of Type Ia supernovae will reside. Given one full year of uninterrupted operation, LISA should be able to measure the rate at which the gravitational-wave frequency $f$ and, hence, the orbital period is changing in the highest frequency subpopulation of our Galaxy's DWD systems. We provide a formula by which the distance to each DWD system in this subpopulation can be determined; in addition, we show how the masses of the individual white dwarf stars in mass-transferring systems may be calculated.
