description: Σκοπός της παρούσας εργασίας ήταν η έρευνα, η μελέτη και η κριτική παρουσίαση της επτανησιακής εφημερίδας Το Μέλλον (Ζάκυνθος, 1849-1851). Η εργασία διαρθρώνεται σε δύο μέρη. Στο Α΄ μέρος, επιχειρήσαμε την ιστορική ένταξη της εφημερίδας και τη σκιαγράφηση του ιδεολογικού προφίλ της, με άξονα τη στάση της απέναντι στα μείζονα πολιτικά διακυβεύματα της εποχής της. Στη συνέχεια, την συγκρίναμε με δύο σύγχρονές της επτανησιακές εφημερίδες. Έπειτα, παρουσιάσαμε τα στοιχεία ταυτότητας της εφημερίδας και των συντακτών της, καθώς και την ύλη της. Εξετάσαμε ξεχωριστά το λογοτεχνικό και φιλολογικό υλικό της εφημερίδας. Τέλος, διατυπώσαμε τα συμπεράσματά μας. Στο Β΄ μέρος, παρουσιάσαμε την πρωτογενή ερευνητική δουλειά πάνω στην οποία στηρίχτηκε το Α΄ μέρος (αποδελτίωση και ευρετηρίαση). Για την αποδελτίωση της εφημερίδας, δημιουργήσαμε αναλυτικά φυλλάδια για κάθε φύλλο της εφημερίδας και ξεχωριστό λογοτεχνικό και φιλολογικό παράρτημα. Ακόμα, αναφερθήκαμε αναλυτικά στη διαδικασία της ευρετηρίασης και παραθέσαμε τα ευρετήρια. Τέλος, συντάξαμε τη βιβλιογραφία.
description: The aim of this study was to inquiry, study and critically present the ionian newspaper The Future (Zante, 1849-1851). The study is divided in two parts. In part A, we attempted the historical integration of the newspaper and the presentation of its ideological profile, according to its stand towards the major political stakes of its era. Next, we compared it with two contemporaneous ionian newspapers. Then, we presented the identity of the newspaper, of its editors and also its content. We examined separately the literary and philological material of the newspaper. Finally, we concluded. In part B, we presented the primary inquiring work on which part A was based (cataloguing and composing indices). In order to produce the indexing of the newspaper, we created for each newspaper issue analytical fiches and a separate literal and philological appendix. Furthermore, we analyzed the procedure of composing indices and we presented them. Finally, we composed the literature review.

description: We present an analysis of the stellar populations in a sample of ~7000 galaxies from the 6dF Galaxy Survey (6dFGS). We derive ages and metallicities using stellar population models. We also derive dynamical masses and dynamical mass-to-light ratios by combining central velocity dispersions with global photometry in B, R and K bands. Together, these data allow to reduce the degeneracies between age, metallicity and star formation burst-strength that have limited previous studies. We find old galaxies exhibit a mass-metallicity relation with slope d[Fe/H]/dlogM = 0.25, while young galaxies show slopes consistent with zero. When we account for the effects of the mass-metallicity relation, we obtain a single, consistent relation between mass-to-light ratio and mass for old galaxies in all passbands. As we have accounted for stellar population effects, this relation must have a dynamical origin. However, we demonstrate that any simple trend between mass-to-light-ratio and mass or luminosity is inconsistent with the observations, and that a more complex relationship must exist. We find the central regions of galaxies often exhibit young stellar populations. However it is only in the lowest-mass galaxies (~10^{10} M$_{\odot}$) that these populations are evident in the global photometry. In higher-mass galaxies, young central populations have decreasing influence on the global photometry, with there being no discernible impact in galaxies more massive than ~2x10^{11} M$_{\odot}$. We conclude that the young stellar populations detected in spectroscopic studies are generally centrally concentrated, and that there is an upper limit on the mass of star-forming events in massive galaxies. These results have ramifications for mass-to-light ratios estimated from photometric observations.

description: We present a detailed analysis of 99 optically thin C III absorption systems at redshift, $0.2 \le z \le 0.9$ associated with neutral hydrogen column densities in the range, $15 \le {\rm log}$ $N_{\rm H\,I}$ ($cm^{-2}$) $\le 16.2$. Using photoionization models, we infer the number density ($n_{\rm H}$), C-abundance ($[C/H]$) and line-of-sight thickness ($L$) of these systems in the ranges, $-3.4 \le$ log $n_{\rm H}$ (in $cm^{-3}$) $\le -1.6$, $-1.6 \le [C/H] \le 0.4$, and 1.3 pc $\le L \le$ 10 kpc, respectively with most of the systems having sub-kpc scale thickness. We combine the low$-z$ and previously reported high$-z$ ($2.1\le z\le 3.3$) optically thin C III systems to study the redshift evolution and various correlation between the derived physical parameters. We see a significant redshift evolution in $n_{\rm H}$, $[C/H]$ and $L$. We compare the redshift evolution of metallicity in C III systems with those of various types of absorption systems. We find that the slope of $[C/H]$ vs. $z$ for C III absorbers is stepper compared to the redshift evolution of cosmic metallicity of the damped \lya\ sample (DLAs) but consistent with that of sub$-$DLAs. We find the existence of strong anti-correlation between $L$ vs. $[C/H]$ for the combined sample with a significance level of 8.39$σ$. We see evidence of two distinct $[C/H]$ branch C III populations (low$-[C/H]$ branch, $[C/H]$ $\le -1.2$ and high$-[C/H]$ branch, $[C/H]$ $> -1.2$) in the combined C III sample when divided appropriately in the $L$ vs. $N_{\rm C\,III}$ plane. Further studies of C III absorbers in the redshift range, $1.0 \le z \le 2.0$ is important to map the redshift evolution of these absorbers and gain insights into the time evolution physical conditions of the circumgalactic medium.

description: We show that the massless higher spin four-dimensional particle model with bosonic counterpart of N=1 supersymmetry respects SU(3,2) invariance. We extend this particle model to a superparticle possessing $SU(3,2|1)$ supersymmetry which is a closure of standard four-dimensional N=1 superconformal symmetry $SU(2,2|1)$ and its bosonic SU(3,2) counterpart. The new massless higher spin D=4 superparticle model describes trajectories in Minkowski superspace $(x^μ, θ^α, \barθ^{\dotα})$ extended by the commuting Weyl spinor $ζ^α$, $\barζ^{\dotα}=(ζ^α)^\ast$. We find the relevant phase space constraints and quantize the model. As a result of quantization we obtain the superwave function which describes an infinite sequence of four-dimensional massless chiral superfields with arbitrary external helicity indices.

Metastable Helium Absorptions with 3D Hydrodynamics and Self-Consistent Photochemistry I: WASP-69b, Dimensionality, XUV Flux Level, Spectral Types, and Flares

description: The metastable Helium (He*) lines near $10830~{\rm A}$ are ideal probes of atmospheric erosion--a common phenomenon of close-in exoplanet evolution. A handful of exoplanet observations yielded well-resolved He* absorption features in transits, yet they were mostly analyzed with 1D isothermal models prescribing mass-loss rates. This work devises 3D hydrodynamics co-evolved with ray-tracing radiative transfer and non-equilibrium thermochemsitry. Starting from the observed stellar/planetary properties with reasonable assumptions about the host's high energy irradiation, we predict from first principle the mass loss rate, the temperature and ionization profiles, and 3D outflow kinematics. Our simulations well reproduce the observed He* line profiles and light curves of WASP-69b. We further investigate the dependence of He* observables on simulation conditions and host radiation. The key findings are: (1) Simulations reveal a photoevaporative outflow ($\sim 0.5~M_{\oplus}~{\rm Gyr}^{-1}$) for WASP-69b without a prominent comet-like tail, consistent with the symmetric transit shape (Vissapragada et al. 2020). (2) 3D simulations are mandatory for hydrodynamic features, including Coriolis force, advection, and kinematic line broadening. (3) EUV ($>13.6~{\rm eV}$) photons dominate photoevaporative outflows and populate He* via recombination; FUV is also detrimental by destroying He*; X-ray plays a secondary role. (4) K stars hit the sweet spot of EUV/FUV balance for He* line observation, while G and M stars are also worthy targets. (5) Stellar flars create characteristic responses in the He* line profiles.

description: Within local-spin-density functional theory, we have investigated the `dissociation' of few-electron circular vertical semiconductor double quantum ring artificial molecules at zero magnetic field as a function of inter-ring distance. In a first step, the molecules are constituted by two identical quantum rings. When the rings are quantum mechanically strongly coupled, the electronic states are substantially delocalized, and the addition energy spectra of the artificial molecule resemble those of a single quantum ring in the few-electron limit. When the rings are quantum mechanically weakly coupled, the electronic states in the molecule are substantially localized in one ring or the other, although the rings can be electrostatically coupled. The effect of a slight mismatch introduced in the molecules from nominally identical quantum wells, or from changes in the inner radius of the constituent rings, induces localization by offsetting the energy levels in the quantum rings. This plays a crucial role in the appearance of the addition spectra as a function of coupling strength particularly in the weak coupling limit.

Metastable Helium Absorptions with 3D Hydrodynamics and Self-Consistent Photochemistry II: WASP-107b, Stellar Wind, Radiation Pressure, and Shear Instability

description: This paper presents simulations of the metastable helium (He*) observations of WASP-107b, so far the highest signal-to-noise ratio detection that is confirmed by three different instruments. We employ full 3D hydrodynamics coupled with co-evolving non-equilibrium thermochemistry and ray-tracing radiation, predicting mass loss rates, temperature profiles, and synthetic He* line profiles and light curves from first principles. We found that a stellar wind stronger than solar is demanded by the observed heavily blueshifted line profile and asymmetric transit light curve. Contrary to previous beliefs, we argue that radiation pressure can be important for Ly$α$ observations but {\it not} He*. We found WASP-107b is losing mass at a rate of $\dot{M} \simeq 1.0\times 10^{-9}~M_\oplus~{\rm yr}^{-1}$. Although $\dot{M}$ varies by $<1~\%$ given constant wind and irradiation from the host, shear instabilities still emerge from wind impacts, producing $\sim 10~\%$ fluctuations of He* transit depths over hour-long timescales. The common assumption that He* transit depth indicates the fluctuation of $\dot{M}$ is problematic. The trailing tail is more susceptible than planet adjacency to the shear instabilities, thus the line profile is more variable in the blue-shifted wing, while the transit light curve is more variable after mid-transit. We stress the synergy between Ly$α$ (higher altitudes, lower density) and He* (lower altitudes, higher density) transit observations, particularly simultaneous ones, yield better understanding of planetary outflows and stellar wind properties.

description: In this work, we introduce the notion of Ball dentable property in Banach spaces. We study certain stability results for the $w^*$-Ball dentable property leading to a discussion on Ball dentability in the context of ideals of Banach spaces. We prove that the $w^*$-Ball-dentable property can be lifted from an $M$-ideal to the whole Banach Space. We also prove similar results for strict ideals of a Banach space. We note that the space $C(K,X)^*$ has $w*$-Ball dentable property when $K$ is dispersed and $X^\ast$ has the $w^*$-Ball dentable property.

Approximate sensitivities for the multi-dimensional electromagnetic inverse problem
Creators: name: Farquharson, Colin Glennie
Publisher: name: University of British Columbia
Year: 2009

description: Inversion of measurements from a geophysical electromagnetic survey to produce a two- or three-dimensional conductivity model of the Earth is computationally demanding. The classical approach is to linearise the inverse problem and iterate towards the solution. A typical, modern version of this approach is described in the initial part of this thesis, and applied to the one-dimensional inversion of time-domain electromagnetic data. One of the most time-consuming parts of a linearised, iterative inversion procedure is the generation of the Jacobian matrix of sensitivities. In this thesis, I have developed an approximate method for generating these sensitivities. The approximation is based on the adjoint-equation method in which the sensitivities are obtained by integrating, over an individual cell, the scalar product of an adjoint field (the adjoint Green’s function) with the electric field produced by the sources for the geophysical survey. Instead of calculating the adjoint field in the multi-dimensional conductivity model, an approximate adjoint field is computed in a homogeneous or layered halfspace, or using the Born approximation. This approximate adjoint field is significantly quicker to compute than the true adjoint field and leads to considerable reductions in the time required to generate the Jacobian matrix of sensitivities. The time-differences were found to be of one or two orders of magnitude for the small examples considered in this thesis, and this saving will further increase with the size of the problem. The approximate sensitivities were compared to the accurate sensitivities for two and three-dimensional conductivity models, and for both artificial sources and the plane wave source of magnetotellurics. In all the examples considered, the approximate sensi tivities appeared to be sufficiently accurate to allow an iterative inversion algorithm to converge to an acceptable model. This was emphasised by the successful inversion, using approximate sensitivities, of two sets of magnetotelluric data: a synthetic data-set and a sub-set of the COPROD2 data.

description: Currently, soil structure interaction in energy piles has not been understood thoroughly. One of the important underlying features is the effect of tip and head restraints on displacement, strain and stress in energy piles. This study has investigated thermo-mechanical response of energy piles subjected to different end restraints by using recently found analytical solutions, thus providing a fundamental, rational, mechanics-based understanding. End restraints are found to have a substantial effect on thermo-mechanical response of energy piles, especially on thermal axial displacement and axial stress in the pile. Head restraint imposed by interaction of an energy pile with the superstructure led to a decrease in the magnitude of head displacement and increase in axial stress, while decreasing the axial strain. The impact of head restraint was more pronounced in end bearing than in fully floating energy piles.

description: Spectra comprised of hundreds of time-components for absorption path lengths up to 130 km have been recorded around 1050 nm by combining two recent techniques, intracavity laser spectroscopy with vertical external cavity surface emitting multiple-quantum-well lasers and time-resolved Fourier transform spectroscopy. A sensitivity of 1 10^{-10} cm^{-1}.Hz^{-1/2} is achieved, for simultaneously acquired 10^4 spectral elements, three orders of magnitude better than the sensitivity obtained in previous similar experiments. Specific advantages of the method, especially for frequency and intensity metrology of weak absorption transitions, are discussed.

This can explain the recent experimental data on the pseudogap enhancement of Ni substituted NdBa_2{Cu_{1-y}Ni_y}O_6.8 from Pimenov et al. (Phys. Rev. Lett. 94, 227003 (2005)).

description: We present an analysis of the Evershed effect observed with a resolution of 0.2 arcsec. Using the new Swedish 1-m Solar Telescope and its Littrow spectrograph, we scan a significant part of a sunspot penumbra. Spectra of the non-magnetic line Fe I 7090.4 A allows us to measure Doppler shifts without magnetic contamination. The observed line profiles are asymmetric. The Doppler shift depends on the part of the line used for measuring, indicating that the velocity structure of penumbrae remains unresolved even with our angular resolution. The observed line profiles are properly reproduced if two components with velocities between zero and several km/s co-exist in the resolution elements. Using Doppler shifts at fixed line depths, we find a local correlation between upflows and bright structures, and downflows and dark structures. This association is not specific of the outer penumbra but it also occurs in the inner penumbra. The existence of such correlation was originally reported by Beckers & Schroter (1969), and it is suggestive of energy transport by convection in penumbrae.

description: Parker Solar Probe (PSP) aims at exploring the nascent solar wind close to the Sun. Meanwhile, PSP is also expected to encounter small objects like comets and asteroids. In this work, we survey the ephemerides to find a chance of recent encounter, and then model the interaction between released dusty plasmas and solar wind plasmas. On 2019 September 2, a comet-like object 322P/SOHO just passed its perihelion flying to a heliocentric distance of 0.12 au, and swept by PSP at a relative distance as close as 0.025 au. We present the dynamics of dust particles released from 322P, forming a curved dust tail. Along the PSP path in the simulated inner heliosphere, the states of plasma and magnetic field are sampled and illustrated, with the magnetic field sequences from simulation results being compared directly with the in-situ measurements from PSP. Through comparison, we suggest that 322P might be at a deficient activity level releasing limited dusty plasmas during its way to becoming a "rock comet". We also present images of solar wind streamers as recorded by WISPR, showing an indication of dust bombardment for the images superposed with messy trails. We observe from LASCO coronagraph that 322P was transiting from a dimming region to a relatively bright streamer during its perihelion passage, and simulate to confirm that 322P was flying from relatively faster to slower solar wind streams, modifying local plasma states of the streams.

description: The present study examines the opinions of primary and secondary school teachers concerning the application of cooperative teaching and learning forms in multicultural classrooms. In particular, ten teachers from schools of the Larissa prefecture participated in the research, which was conducted in the period October – November 2013. We used as a research tool the technique of the semi-structured interview, posing eight-teen open questions. Both the theoretical and the empirical part of the study showed the importance of cooperative teaching and learning forms for every classroom, focusing, however, on multicultural classrooms. The opinions expressed by the teachers who took part in the research revealed, among other things, the students’ positive response towards cooperative teaching and learning forms, which they find interesting, regardless of their language and cultural background. The answers of the teachers participating in the present study also made clear the insufficiency of teachers’ initial training and their scientific knowledge about this specific subject area; therefore, the need for relevant in-service training is stressed out.

description: Epidemiological studies of cruciferous crops (Brassica oleracea) consumption show reduction in incidence and progression of prostate and colon cancer among the others. Cabbage, broccoli and cauliflower are source of organo-sulphur compounds: S-methyl cysteine sulphoxide and glucosinolates. Metabolism of glucoraphanin in gut lumen leads to sulforaphane (SF), exerting mild pro-oxidant activity required to induction of phase 2 and antioxidant genes that in result reduces level of inflammatory cytokines. We are conducting diet intervention prostate cancer study to elucidate effects of increased levels of SF on molecular phenotype in healthy prostate tissue. The aims of this pilot study are to provide for the first time evidence in humans for the critical role of SF in regulating metabolism, and to identify the underlying mechanisms by which SF can reduce the risk of aggressive prostate cancer.

For the sake of improved interpretation of simultaneous gene expression and metabolism response we are challenging state-of-the-art methods to integrate omics data. In integration of multiple data types e.g. transcriptomics and metabolomics, the typical statistical approaches as canonical correlation analysis (CCA) are failing due to small number of observations (e.g. conditions, diet etc.) in comparison to data size (number of genes, metabolites). Modifications designed to cope with this issue are not ideal due to the need to add simulated data resulting in a lack of p-value computation or by pruning of variables hence losing potentially valid information. Instead, our approach makes use of verified or putative molecular interactions or functional association to guide analysis. The workflow includes dividing of data sets to reach the expected data structure, statistical analysis within groups and interpretation of results. By applying pathway and network analysis, data obtained by various platforms are grouped with moderate stringency to avoid functional bias. As a consequence CCA and other multivariate models can be applied to calculate robust statistics and provide easy to interpret associations between metabolites and genes to leverage understanding of metabolic response. Effective integration of lipidomics and transcriptomics is demonstrated on publicly available murine nutrigenomics data sets. We are able to demonstrate that our approach improves detection of genes related to lipid metabolism, in comparison to applying statistics alone. This is measured by increased percentage of explained variance (95% vs. 75-80%) and by identifying new metabolite-gene associations related to lipid metabolism.

description: The study describes levels of thinking in regard to the design of statistical studies. Clinical interviews were conducted with 15 students. Each student was enrolled in high school or was a recent graduate. The students interviewed represented a range of mathematical backgrounds. During the clinical interview sessions, students were asked how they would go about designing studies to answer several different quantifiable questions. Several levels of sophistication were identified in their responses. The levels of sophistication in response are discussed in terms of the Biggs and Collis (1982, 1991) cognitive model.

Στην παρούσα εργασία κατασκευάστηκε ένα ερωτηματολόγιο που έχει ως στόχο να καταγράψει θέματα ταυτότητας των Παλλινοστούντων. Η υπόθεση είναι ότι οι Παλλινοστούντες έχουν ισχυρούς δεσμούς με την Ελληνική παράδοση και την Ελληνική γλώσσα ανεξαρτήτως του τόπου διαμονής τους. Το δείγμα το οποίο χρησιμοποιήθηκε για την έρευνα προέρχεται από στενό φιλικό μου περιβάλλον. Το δείγμα διαφέρει ως προς την ηλικία, το φύλο, τις σπουδές, το επάγγελμα και την οικογενειακή κατάσταση. Τα άτομα τα οποία δέχτηκαν και απάντησαν στο ερωτηματολόγιο είναι Παλιννοστούντες, οι οποίοι μένουν και εργάζονται στην Ελλάδα και Έλληνες ομογενείς οι οποίοι κατοικούν και εργάζονται στη Ρωσία. Ειδικότερα, εξετάζεται ο τρόπος με τον οποίο ζουν πραγματικά και φαντασιακά ανάμεσα σε δυο χώρες, ανάμεσα σε δυο πατρίδες, την Ελλάδα και την Πρώην Σοβιετική Δημοκρατία στην οποία γεννήθηκαν ή /και μεγάλωσαν.
description: The present work is based on a questionnaire, which aims to record identity issues of Repatriated Greeks of the Former Soviet Union. There will be comparative study for recording behaviors of Repatriated Greeks in tradition and language issues. The hypothesis is that Repatriated Greeks have strong ties with the Greek Tradition and Greek language, irrespective where they live. The sample that takes part in the research comes from my close environment. They are Repatriated Greeks who live and work in Greece and Greeks who still live and work in Russia or former Soviet Democracies.The sample differs in age, gender, studies, profession and marital status. We will study the Pontic Greeks from the Former Soviet Union who have come for permanent establishment in Greece. Particularly, we will investigate the matter that they live their real and imaginary life, between two countries, Greece and the Former Soviet Democracy, in which they were born and raised.

description: The indigenously organised IT artefact represents a version of technology that is not entirely familiar to most indigenous communities. An indigenous IT artefact can be many things in today’s digital world; it can be a mobile application for a tribal language or a website that stores tribal information. This study provides a procedure to guide the construction of a 3d model of a taonga as a proxy for an IT artefact. Here, I create the TAIHONOHONO framework grounded in a set of principles that adhere to being responsible, reciprocal, and respectful during the construction of a 3d model.
Distant perturbation asymptotics in window-coupled waveguides. I. The non-threshold case

description: We consider a pair of adjacent quantum waveguides, in general of different widths, coupled laterally by a pair of windows in the common boundary, not necessarily of the same length, at a fixed distance. The Hamiltonian is the respective Dirichlet Laplacian. We analyze the asymptotic behavior of the discrete spectrum as the window distance tends to infinity for the generic case, i.e. for eigenvalues of the corresponding one-window problems separated from the threshold.

description: The purpose of this Master’s Theses has been to examine whether the suggested methods, as well as the curriculum of the Ministry, promote a cooperative apprenticeship regarding the French lessons of the Greek primary school. In the first part, the cooperative apprenticeship was studied through the bibliography. Furthermore, the curriculum of the Ministry was examined thoroughly. Finally, the French syllabus, which is recommended by the Greek Ministry, was analyzed in order to accredit if it can be characterized as a cooperative one.

description: The study describes students’ patterns thinking for statistical problems set in two different contexts. Fifteen students representing a wide range of experiences with high school mathematics participated in problem-solving clinical interview sessions. At one point during the interviews, each solved a problem that involved determining the typical value within a set of incomes. At another point, they solved a problem set in a signal-versus-noise context (Konold & Pollatsek, 2002). Several patterns of thinking emerged in the responses to each task. In responding to the two tasks, some students attempted to incorporate formal measures, while others used informal estimating strategies. The different types of thinking employed in using formal measures and informal estimates are described. The types of thinking exhibited in the signal-versus-noise context are then compared against those in the typical value context. Students displayed varying amounts of attention to both data and context in formulating responses to both problems. Suggestions for teachers in regard to helping students attend to both data and context when analyzing statistical data are given.

description: We present uniformly reprocessed and re-calibrated data from the RoboPol programme of optopolarimetric monitoring of active galactic nuclei (AGN), covering observations between 2013, when the instrument was commissioned, and 2017. In total, the dataset presented in this paper includes 5068 observations of 222 AGN with Dec > -25 deg. We describe the current version of the RoboPol pipeline that was used to process and calibrate the entire dataset, and we make the data publicly available for use by the astronomical community. Average quantities summarising optopolarimetric behaviour (average degree of polarization, polarization variability index) are also provided for each source we have observed and for the time interval we have followed it.

The Pre-cataclysmic Binary HS 1136+6646 May Have a Companion

description: Because of the similarity of the primary star of HS 1136+6646 to the planetary nebula central star BE Ursae Majoris, we did wide field imaging of the former with an H-alpha filter. No nebulosity was detected. On the other hand, the point spread function of the star appeared extended. A partially-resolved red component is detected in the image with the five-band Sloan Digital Sky Survey. Most importantly, a companion is easily resolved in the HST acquisition image for the published STIS observation. A companion to the pre-cataclysmic binary is present at a separation of 1.349'' at position angle 54.4 deg. Evidence indicates that it is likely of K spectral type. We cannot demonstrate conclusively that this component has common proper motion with the close binary. However, the similar apparent z magnitudes and spectral types of HS 1136+6646B and the resolved component make it likely that we have in reality a hierarchial triple system. In any case, the presence of this component needs to be taken into account in future ground-based studies.

description: Even under constant external conditions, the expression levels of genes fluctuate. Much emphasis has been placed on the components of this noise that are due to randomness in transcription and translation; here we analyze the role of noise associated with the inputs to transcriptional regulation, the random arrival and binding of transcription factors to their target sites along the genome. This noise sets a fundamental physical limit to the reliability of genetic control, and has clear signatures, but we show that these are easily obscured by experimental limitations and even by conventional methods for plotting the variance vs. mean expression level. We argue that simple, global models of noise dominated by transcription and translation are inconsistent with the embedding of gene expression in a network of regulatory interactions. Analysis of recent experiments on transcriptional control in the early Drosophila embryo shows that these results are quantitatively consistent with the predicted signatures of input noise, and we discuss the experiments needed to test the importance of input noise more generally.

The effect of steam injection on the electrical conductivity of sand and clay
Creators: name: Butler, David Buchanan
Publisher: name: University of British Columbia
Year: 2009

description: To interpret electrical surveys used to monitor subsurface steam-injection projects, one needs to know whether steam zones are resistive or conductive relative to initial conditions. This can be determined through laboratory measurements of the effects of steam injection on the electrical conductivity of sand. Experiments presented in chapter 2 measured the combined effects of the salinity of the boiler feedwaters and the steam quality - the fraction of the injected flux that is vapour. The injection of low quality steam, boiled from a saline solution, into clean sand saturated with the same solution, resulted in a net decrease in conductivity, and a constant equilibrium conductivity in the steam zone. The injection of high-quality steam, using the same solutions, resulted in conductivity dropping first to a minimum, and then increasing to an equilibrium value similar to that seen in the low quality injection. This localized conductivity minimum became progressively less conductive with time, and travelled with the steam front. The appearance of the conductivity minimum at the steam front can be attributed to the formation of a dilution bank, which temporarily decreases the local salinity. This suggests that many steam injections will create steam zones with electrically resistive fronts, which can be used to track the steam. The effects of clay on the electrical conductivity of steam zones is further investigated in chapter 3. Experimental and numerical results indicate that clay-bearing steam zones can be electrically conductive relative to initial conditions, in part due to water saturations in the steam zones that are higher than those in comparably steam-flooded clean sands. However, it is still likely that high quality steam injections will result in resistive leading edges of the steam zones. In low quality steam injections, where dilution banks do not form around the front, it is more likely that steam zones are entirely conductive relative to initial conditions, particularly in fresh water environments.
