description: We present J-band imaging and H+K-band low-resolution spectroscopy of 2MASS1207-3932 AB, obtained with VLT NACO. For the putative planetary mass secondary, we find J = 20.0+/-0.2 mag. The HK spectra of both components imply low gravity, and a dusty atmosphere for the secondary. Comparisons to synthetic spectra yield Teff_A ~ 2550+/-150K, and Teff_B ~ 1600+/-100K, consistent with their late-M and mid-to-late L types. For these Teff, and an age of 5-10 Myrs, evolutionary models imply M_A ~ 24+/-6 M_Jup and M_B ~ 8+/-2 M_Jup. Independent comparisons of these models to the observed colors, spanning ~I to L', also yield the same masses and temperatures. Our primary mass agrees with other recent analyses; however, our secondary mass, while still in the planetary regime, is 2-3 times larger than claimed previously. This discrepancy can be traced to the luminosities: while the absolute photometry and Mbol of the primary agree with theoretical predictions, the secondary is ~ 2.5+/-0.5 mag fainter than expected in all bands from I to L' and in Mbol. This accounts for the much lower secondary mass (and temperature) derived earlier. We argue that this effect is highly unlikely to result from a variety of model-related problems, and is instead real. This conclusion is bolstered by the absence of any luminosity problems in either the primary, or in AB Pic B which we also analyse. We therefore suggest grey extinction in 2M1207B, due to occlusion by an edge-on circum-secondary disk. This is consistent with the observed properties of edge-on disks around T Tauri stars, and with the known presence of a high-inclination evolved disk around the primary. Finally, the system's implied mass ratio of ~0.3 suggests a binary-like formation scenario. (abridged)

description: Nowadays, there is a growing need especially from biomedical applications, for high computing power and large storage facility systems. Grid is expected to solve all the relevant computational and storage problems that scientists have difficulty in facing. A lot of work is done in the area of Interface. Accessing grid power in a simple way is the number one topic in the scientific community. The purpose of this work was to study the Grid technology and the implementation of this technology in biomedical applications. Great attention was given to the planning and development of user friendly Interfaces. Test cases were used to test the interface, by executing exhaustive computational biomedical applications. Before the execution of the biomedical applications, the appropriate modifications and configurations were applied in order to run on the Grid, with the help of the user friendly interface.

description: Laboratory studies have shown that when online search en-gines’ results are annotated with privacy indicators, someconsumers will pay a premium to make purchases from sitesthat have better privacy policies. To examine whether pri-vacy indicators in search results also influence browsing be-havior outside the laboratory, we conducted a field studyin which participants used a search engine with privacy in-dicators. We collected over 15,000 search queries from 460participants over a 10-month period. We found that whensearch results were annotated with privacy indicators, par-ticipants were more likely to visit sites with high privacyratings, even when they appeared towards the bottom of thesearch results page. Sites with low privacy ratings did nothave significantly different visitation rates than sites withoutany privacy ratings

description: The present dissertation presents a research about the European eT-winning project and its application by seven Greek schools. The aim of the study is to register the literacy practices, as they are formed by the Informa-tion and Communication Technologies (ICTs), in which the students of these schools participate. Using the interviews of the teachers as a tool for collect-ing data and developing Multiliteracies theory for the qualitative analysis of data, a clear perspective of the working methods that the school teams had during their cooperation with the teams of foreign schools is given. The study shows that within the eTwinning project the traditional role of teachers and students is transformed, the collaborative team work is applied and many sources of information are used in order to complete the projects. As a result, students are involved with many literacy practices.
Theory of high energy features in angle-resolved photo-emission spectra of hole-doped cuprates

description: The recent angle-resolved photoemission measurements performed up to binding energies of the order of 1eV reveals a very robust feature: the nodal quasi-particle dispersion breaks up around 0.3-0.4eV and reappears around 0.6-0.8eV. The intensity map in the energy-momentum space shows a waterfall like feature between these two energy scales. We argue and numerically demonstrate that these experimental features follow naturally from the strong correlation effects built in the familiar t-J model, and reflect the connection between the fermi level and the lower Hubbard band. The results were obtained by a mean field theory that effectively projects electrons by quantum interference between two bands of fermions instead of binding slave particles.

description: We use MUSE adaptive optics (AO) data in Narrow Field Mode to study the properties of the ionised gas in MR 2251-178 and PG 1126-041, two nearby (z~0.06) bright quasars hosting sub-pc scale Ultra Fast Outflows (UFOs) detected in the X-ray band. We decompose the optical emission from diffuse gas into a low- and a high-velocity components. The former is characterised by a clean, regular velocity field and a low (~80 km/s) velocity dispersion. It traces regularly rotating gas in PG 1126-041, while in MR 2251-178 it is possibly associated to tidal debris from a recent merger or flyby. The other component is found to be extended up to a few kpc from the nuclei, and shows a high (~800 km/s) velocity dispersion and a blue-shifted mean velocity, as expected from AGN-driven outflows. We estimate mass outflow rates up to a few Mo/yr and kinetic efficiencies between 0.1-0.4 per cent, in line with those of galaxies hosting AGNs of similar luminosity. The momentum rates of these ionised outflows are comparable to those measured for the UFOs at sub-pc scales, consistent with a momentum-driven wind propagation. Pure energy-driven winds are excluded unless about 100x additional momentum is locked in massive molecular winds. By comparing the outflow properties of our sources with those of a small sample of well-studied QSOs hosting UFOs from the literature, we find that winds seem to systematically lie either in a momentum-driven or in an energy-driven regime, indicating that these two theoretical models bracket very well the physics of AGN-driven winds.

description: In the present work changes in the topography of less resistant K2O-CaO-SiO2 and more stable Na2O-CaO-Al2O3-SiO2 glasses were studied in-situ by using a high-resolution atomic force microscope (AFM) in contact mode. The images were taken in air and in water, using a special liquid cell in the latter case. Fresh fracture surfaces were prepared in the corresponding media and the samples were transferred immediately into the AFM. The freshly fractured K2O-containing glasses displayed an irregular ripple pattern in air with ripple diameters of (80 ± 20) nm, heights < 1.2 nm and root mean square (rms) roughnesses < 0.8 nm. With ongoing exposure time, these glasses form a gel layer, isolated droplets and larger drops which can even coalesce. Also partially crystalline secondary reaction products can be observed in the drops. The large drops themselves displayed topographies with a ripple pattern similar to that found on the gel layer-coated surfaces. The drops and the gel layers are soft and may be penetrated and moved by the scanning tip. The in-situ investigation of these glasses in water revealed topographies with a ripple pattern similar to freshly prepared surfaces. This pattern did not change with exposure time, obviously because the water in excess rinsed away possible reaction products. The more resistant Al2O3-containing glasses show a dissimilar behaviour. The ripple pattern on the fracture surfaces is smaller and does not change even after days. Due to the absence of capillary forces and lower van der Waals forces the ripple diameters are smaller in water than in air. Glasses with a high degree of network polymerization also show smaller ripples than glasses with more nonbridging oxygens.
Chemical durability of sodium disilicate glasses in different corrosion media at neutral to basic pH values

description: The chemical corrosion of sodium disilicate glasses in neutral to basic media was investigated. H2O, 1 mol/l NaOH, 1 mol/l LiOH, and a dilution series of sodium silicate solutions with a molar SiO2:Na2O ratio of 2.18 were used as corrosion media in static corrosion tests at temperatures of 30 °C and corrosion times up to 180 d. The corrosion process was characterized gravimetrically and in some cases by chemical analysis. Additionally, the temperature dependence of the corrosion in H2O at temperatures up to 70 °C was investigated. The nature of the corrosion process depends on the character of the corrosion media: The corrosion in 1 mol/l NaOH and 1 mol/l LiOH follows predominantly a square root time law, whereas corrosion in H2O or in sodium silicate solutions can be described by a linear time law. An additional result is that the corrosion rates increase in all cases with pH: in the case descnbed here corrosion in H2O and in alkaline silicate solutions proceeds faster than corrosion in sodium or lithium hydroxide solutions with higher pH values. The dilution series of sodium silicate solutions was used to check the dependence of the corrosion process on the concentration of glass dissolution products in the leachate. The results indicate the importance of surface adsorption processes.

description: In this paper, we prove that there exists an equivalence between 2-category of smooth Deligne-Mumford stacks with torus-embeddings and actions, and the 1-category of stacky fans. For this purpose, we obtain two main results. The first is to investigate a combinatorial aspect of the 2-category of toric algebraic stacks defined in \cite{I2}. We establish an equivalence between the 2-category of toric algebraic stacks and the 1-category of stacky fans. The second is to give a geometric characterization theorem for toric algebraic stacks.

Evaluation of chemical indexes to predict the dissolution rate of amorphous silicate fibers in a physiological salt solution

description: In order to predict the biosolubihty of amorphous inorganic fibers through a chemical index, dissolution experiments were carried out of the amorphous silicate fibers in the RO-SiO2 system (RO: alkaline earth oxide such as MgO, CaO and SrO) in a physiological salt Solution at 40 °C over 50 h with shaking at 120 cycles/min. The correlation was analyzed between the dissolution rate and each index such as carcinogenicity index (KI), nonbridging oxygen index (NBO), free energy of hydration (ΔG0) and molar ratio-weighted mean ionic radius of the alkaline earth ions as the glass network modifiers (ravg). These indexes are based on the chemical composition of the fiber. Among these chemical Indexes, KI, NBO and ΔG0 do not show any correlation with the dissolution rate of the fibers. The ravg, suggested in this study, is the only index that shows a linear correlation with the dissolution rate of the fibers. It is concluded that the ravg plays an important role as an indicator of the biosolubility of amorphous silicate fibers of this type. In addition, the ravg may be one of the indexes to classify the newer fibrous materials of this type, which are less biopersistent.

description: The importance of computing in astronomy continues to increase, and so is its impact on the environment. When analyzing data or performing simulations, most researchers raise concerns about the time to reach a solution rather than its impact on the environment. Luckily, a reduced time-to-solution due to faster hardware or optimizations in the software generally also leads to a smaller carbon footprint. This is not the case when the reduced wall-clock time is achieved by overclocking the processor, or when using supercomputers. The increase in the popularity of interpreted scripting languages, and the general availability of high-performance workstations form a considerable threat to the environment. A similar concern can be raised about the trend of running single-core instead of adopting efficient many-core programming paradigms. In astronomy, computing is among the top producers of green-house gasses, surpassing telescope operations. Here I hope to raise the awareness of the environmental impact of running non-optimized code on overpowered computer hardware.

description: We offer a fractonic perspective on a familiar observation -- a flat sheet of paper can be folded only along a straight line if one wants to avoid the creation of additional creases or tears. Our core underlying technical result is the establishment of a duality between the theory of elastic plates and a fractonic gauge theory with a second rank symmetric electric field tensor, a scalar magnetic field, a vector charge, and a symmetric tensor current. Bending moment and momentum of the plate are dual to the electric and magnetic fields, respectively. While the flexural waves correspond to the quadratically dispersing photon of the gauge theory, a fold defect is dual to its vector charge. Crucially, the fractonic condition constrains the latter to move only along its direction, i.e., the fold's growth direction. By contrast, fracton motion in the perpendicular direction amounts to tearing the paper.

description: This dissertation comprises a theoretical and a research part. The theoretical framework is an attempt to define the potential of intercultural dimensions in museum learning through examing aspects of education, archaeology and museology in order to demonstrate their interconections and their potential to contribute to the discourse on identities as well as to effords towards social inclusion. A synopsis of the international educational approaches to cultural diversity with special references to greek reality and the ethnocentrism of the greek school are presented in the chapter about education. The following chapter, on archaeology and the museum, emphasizes on realization of their political and ideological role & new approaches that aim at the development of a dynamic relationship with society, internationally and in Greece. The research's object is to pin point, record and critically assess actions taken by greek museums, that have an alternative approach to cultural diversity, regarding of the past as well as their contemporary outreach policy. The discussion/conclusions part summarizes the characteristics of the actions presented and tries to place them in the perspective of the theoretical framework.

description: The compositional dependence of the viscosity was studied for two high aluminosilicate melt series: Na2O-CaO-Al2O3-SiO2 (NCAS) and K2O-Na2O-CaO-Al2O3-SiO2 (KNCAS). The viscosity and the glass transition temperature were measured by concentric cylinder viscometry and differential scanning calorimetry, respectively. This work discusses the viscosity predictive model set up by Bottinga and Weill. The temperature dependent constant, D, defining the relative impact of each component on the viscosity, was derived for the compositional range from 35 to 45 mol% SiO2 for KAIO2 and NaAlO2, respectively. With the newly derived D-values, a good agreement was achieved between measured and predicted values.

description: We present the results of an all-sky, deep optical survey for faint Local Group dwarf galaxies. Candidate objects were selected from the second Palomar survey (POSS-II) and ESO/SRC survey plates and follow-up observations performed to determine whether they were indeed overlooked members of the Local Group. Only two galaxies (Antlia and Cetus) were discovered this way out of 206 candidates. Based on internal and external comparisons, we estimate that our visual survey is more than 77% complete for objects larger than one arc minute in size and with a surface brightness greater than an extremely faint limit over the 72% of the sky not obstructed by the Milky Way. Our limit of sensitivity cannot be calculated exactly, but is certainly fainter than 25 magnitudes per square arc second in R, probably 25.5 and possibly approaching 26. We conclude that there are at most one or two Local Group dwarf galaxies fitting our observational criteria still undiscovered in the clear part of the sky, and a roughly a dozen hidden behind the Milky Way. Our work places the "missing satellite problem" on a firm quantitative observational basis. We present detailed data on all our candidates, including surface brightness measurements.

description: Extending previous work on this subject, we evaluate the impact of vector-like fermions at next-to-leading order accuracy in models with a massive vector leptoquark embedded in the $SU(4)\times SU(3)^\prime\times SU(2)_L\times U(1)_X$ gauge group. Vector-like fermions induce new sources of flavor symmetry breaking, resulting in tree-level flavor-changing couplings for the leptoquark not present in the minimal version of the model. These, in turn, lead to a series of non-vanishing flavor-changing neutral-current amplitudes at the loop level. We systematically analyze these effects in semileptonic, dipole and $ΔF=2$ operators. The impact of these corrections in $b\to sνν$ and $b\to cτν$ observables are discussed in detail. In particular, we show that, in the parameter region providing a good fit to the $B$-physics anomalies, the model predicts a $10\%$ to $50\%$ enhancement of $\mathcal{B}(B\to K^{(*)}νν)$.

description: Advancements in information and communications technologies (ICTs) have enabled many developing countries to exploit their comparative advantage in services exports. In developing regions, South Asia has taken the lead in the export of modern services including computer, IT and professional services. During the last decade, South Asia has been able to grow at a reasonable average annual growth rate of almost 7 percent. This growth rate has emanated from the strong performance of South Asia's services sector both in terms of domestic output and exports. This path of service-led growth in South Asia is in sharp contrast to East Asia's high growth, which has been possible through its manufacturing based export orientation. This thesis provides an exploratory analysis of service-led growth in South Asia. First, it explains the growing role of services in the economic growth and development of South Asia, and provides a comparative evaluation of the growth experience of South Asia and East Asia. Second, growth of modern services exports from developing countries are explained and supported by the theoretical and empirical literature, to analyze the different sources of these exports. Third, it explains the growth of modern services exports of South Asia and the export performance of selected modern services of the region, in a global context. Fourth, it provides an objective analysis of the differences in technologies and export potential of selected high performing South and East Asian countries with the developed world. Finally, it examines the intersectoral relationship between the services and agriculture and manufacturing sectors. The study contributes to the debate on the service-led growth path and export orientation, and the findings have important policy implications. The results show that despite the significant growth of modern services exports from South Asia, the region has large potential to further increase these exports. This potential can provide sustainability to the current services dominated growth in the region. Another important implication for policy makers is that sustained growth of high skilled graduates and high end ICT infrastructure are essential for the continuity of modern services export growth. Finally, performance of manufacturing and agriculture sectors are, to some extent, prerequisites for overall services sector growth. -- provide by Candidate.
IR and Raman spectroscopic study of some strontium aluminosilicate glasses

description: Vibrational spectra are measured for strontium aluminosilicate glasses with the composition (in mol%) x SrO ∙ y AI2O3 ∙ (100-x-y) SiO2 (33 ≤ x ≤ 40, 0 ≤ y ≤ 2) with a water content ranging from 0.014 to 0.14 mol ∙ l-1 . The OH bands systematically change with glass composition in both MIR and NIR regions. The ratio of the absorption coefficients α3550/α2800 increases with decreasing number of nonbridging oxygens per tetrahedron (NBO/T; Τ = Si, AI). This indicates an increasing amount of strongly hydrogen bonded OH groups (2800 cm-1) with NBO/T relative to the weakly bonded hydroxyls (3550 cm-1) within the compositional series. Intensity changes in the Raman and IR reflectance spectra also reflect the substitution of Al3+ for Si4+ in the network and the incorporation of Sr2+. The increasing intensity ratio of the Raman bands I945/I1070 with NBO/T indicates an increase of structural units relative to Q^3, as well as the weak shoulder at 870 cm-1 shows a rising amount of Q units. The growing intensity of the IR reflectance band at 930 cm-1 with NBO/T confirms the increasing amount of nonbridging oxygen in the glasses. Α depolarized Raman band at 330 cm-1 was assigned to an Sr-O vibration. For hydrated samples the significantly higher ratio of α3550/α2800 in relation to the basic glasses can be explained by structural changes in the samples due to the water enrichment procedure. The hydroxyl content of the basic and hydrated glasses can be estimated by the so called two-band method with composition independent extinction coefficients for the two IR bands at about 3550 and 2800 cm-1, ε3550 = 80 1 ∙ mol-1 ∙ cm-1 and ε2800 = 170 1 ∙ mol-1 ∙ cm-1, independent of the Al3+ content of the glasses.

description: Η παρέκκλιση των ατόμων από τα κυρίαρχα κανονιστικά πρότυπα συνιστά, σύμφωνα με τον Goffman (2001), τη βασική αιτία για την κοινωνική τους περιθωριοποίηση και τη συρρίκνωση της ανθρώπινης ιδιότητάς τους. Η λογοτεχνία ανέκαθεν υπήρξε ισχυρός φορέας ιδεολογικών μηνυμάτων που άλλοτε έχουν ως στόχο την εδραίωση και άλλοτε την αναθεώρηση των κυρίαρχων κοινωνικών δομών και της κατηγοριοποίησης των ατόμων ευπαθών ομάδων σε αυτές. Η ανίχνευση των στόχων αυτών σε σχέση με τα άτομα με αναπηρία υπήρξε το θέμα της παρούσας έρευνας. Για το λόγο αυτό μελετήθηκαν 53 παιδικά βιβλία Ελλήνων και ξένων συγγραφέων από διαφορετικές χρονικές περιόδους που έχουν ως ήρωες/ ηρωίδες άτομα με αναπηρία. Η ανάλυση περιεχομένου έδειξε πως τα τελευταία χρόνια αυξήθηκαν τα βιβλία που προσεγγίζουν το θέμα της αναπηρίας και πως οι προσεγγίσεις αυτές είναι περισσότερο απαλλαγμένες από απαξιωτικές απεικονίσεις. Ωστόσο, το ποσοστό των βιβλίων παραμένει μικρό σε σύγκριση με το συνολικό αριθμό παιδικών βιβλίων, ενώ ταυτόχρονα μακρύς παραμένει και ο δρόμος μέχρι την πλήρη απαλλαγή των απεικονίσεων αυτών από προκαταλήψεις και στερεότυπα.
description: The declension of some individuals from the applied etiquettes establishes, according to Goffman, the basic reason for their social exclusion and the shrinkage of their human attribute. Fiction has always been a strong carrier of ideological messages that are aimed at the establishment of the revision of the dominant social structures and the classification of individuals from vulnerable groups in them. The detection of those targets in relation to individuals with disabilities was the topic of the present study. 53 children books from different period have been studied. Content analysis showed that recently the number of books on disability increased and that these approachments are more free of degrading portrayals. However the percentage of those books remains low whereas long remains the way till the total release of those portrayals of bias and stereotypes.

description: Ο ιερέας στην Ορθόδοξη Εκκλησία, εκτός του βαθμού του Επισκόπου, είναι έγγαμος. Συνεπώς, βρίσκεται συνεχώς στο μέσο της ενορίας και της οικογένειας του. Η υπερβολική αφοσίωση του στην ενορία, η έντονη κριτική την οποία υφίσταται η οικογένειά του, ο "ασκητικός" τρόπος ζωής των μελών της, είναι προβλήματα τα οποία πιθανόν να προκαλέσουν αντιδράσεις και ένταση τόσο στην πρεσβυτέρα, όσο και στα παιδιά και φυσικά στον ίδιο τον ιερέα. Του λόγου το αληθές μαρτυρεί και η μικρή σε ένταση έρευνα με ερωτηματολόγια σε ιερατικές οικογένειες της Εκκλησίας της Κύπρου. Τέλος, προτείνονται λύσεις και διέξοδοι από τέτοιου είδους καταστάσεις.
description: The clergy of the Orthodox Church are for the most part married, apart from those holding the position of bishop, where marriage is not allowed. It has been noted that the married priest often finds himself at odds between his parish and his family. His over devotion to his parish, the intense criticism which his family is under, the 'ascetic' lifestyle which family members are expected to lead, are problems which can probably cause an adverse reaction and tension for his wife, children and for the priest himself. This subject is examined in this short research study using a questionnaire taken out on priests families from the Church of Cyprus. The results are presented and analysed from the conclusions, solutions are offered and ways out of the above difficulties are given.

description: Upcoming measurements of the highly redshifted 21cm line with next-generation radio telescopes such as HERA and SKA will provide the intriguing opportunity to probe dark matter (DM) physics during the Epoch of Reionization (EoR), Cosmic Dawn, and the Dark Ages. With HERA already under construction, there is a pressing need to thoroughly understand the impact of DM physics on the intergalactic medium (IGM) during these epochs. We present first results of a hydrodynamic simulation suite with $2 \times 512^3$ particles in a $(100 \ h^{-1} \ \text{Mpc})^3$ box with DM annihilation and baryonic cooling physics. We focus on redshift $z \sim 11$, just before reionization starts in our simulations, and discuss the imprint of DM annihilation on the IGM and on structure formation. We find that whereas structure formation is not affected by thermal WIMPs heavier than $m_χ\gtrsim 100 \ \text{MeV}$, heating from $\mathcal{O}$(GeV) DM particles may leave a significant imprint on the IGM that alters the 21cm signal. Cold gas in low density regions is particularly susceptible to the effects of DM heating. We note, however, that delayed energy deposition is not currently accounted for in our simulations.

Theory of the spectral transmittance of Christiansen filters
Creators: name: Hoffnnann, Hans-Jürgen
Publisher: name: Offenbach : Verlag der Deutschen Glastechnischen Gesellschaft
Year: 2003
Subjects: subject: 660

description: Christiansen filters are usually made of grains of transparent materials, such as glass, immersed in a fluid with matching refractive index. If the refractive index of the grains matches that of the fluid the spectral transmittance is maximum. It decreases with increasing difference between the refractive indices. Since a formula due to Raman and Shelyubskii, which is widely used in the literature to describe the spectral transmittance of such filters, has no scientific basis, a new theory is developed taking into account reflection and refraction at the boundaries between grains and fluid. The theory is applied to spheres distributed in the immersion fluid. In this ease, adjustable parameters are not required. For grains of arbitrary shape one needs a statistical description of the boundaries and their orientation. To simplify the procedure an adjustable parameter is introduced to account for such effects. The theory takes into account the aperture angles of the incident beam and of the detector to measure the transmittance. It predicts the dependence of the spectral transmittance as a function of the difference between the refractive indices, the average grain diameters and the thickness of the filter. The inhomogeneity of the refractive index of the glass grains can also be taken into account. The spectral transmittance curves published in the literature are qualitatively quite well described by the calculations. Exact fits, however, are not possible, since the aperture angles are generally not given for the published results. Therefore, experimental investigations controlling all necessary parameters are in progress.
