Heat exchanger fouling by precipitation of calcium phosphates
Creators: name: Singh, Atmajeet
Publisher: name: University of British Columbia
Year: 2008

description: The fouling characteristics of artificially hardened waters containing calcium and orthophosphate ions were investigated. The water was circulated through a steam heated double pipe heat exchanger under turbulent flow conditions. Inlet water temperatures were about 20 to 25°C and the phosphate content about 100 ppm. Experiments were carried out to ascertain the effects of pH, velocity, surface temperature and concentrations of the calcium and the orthophosphate on the fouling process. The fouling behaviour was recorded in terms of the fouling resistance-time curve which was calculated from the time dependence of the overall heat transfer coefficients. Under the constant heat flux condition imposed, the fouling resistance was generally linear in time; however, asymptotic fouling was observed in some cases. The fouling rate was found to be a very strong function of the pH over the range 6.5 to 8.0. The rate was also found to be exponentially dependent on the calculated surface temperature. The initial fouling rate increased linearly with the velocity and with the concentrations of scale forming species. Deposit thickness increased with heated length of the stainless steel test section. In most cases, the deposit was a dense crystalline scale, which had a Ca/P molar ratio of 1.35±0.15. The results are discussed in terms of the ionic equilibrium involved and the solubility and crystallisation kinetics from the literature. It is apparent that the rate of phosphate precipitation is influenced both by surface reaction and mass transfer in the range of the variables studied. Findings are compared with the few prior phosphate fouling studies from the literature. Scale density is reported, and its thermal conductivity estimated using the fouling resistance measurements.

description: Supernovae are the dominant source of chemical enrichment of galaxies, and they are an important source of energy to heat the interstellar medium and accelerate cosmic rays. Our knowledge of supernovae in the Milky Way is based mostly on the study of Galactic supernova remnants (SNRs), providing an (incomplete) record to supernova activity over the last ~100,000 yr. Here we report on an investigation of the spatial distribution of Galactic SNRs. Given the limited number of SNRs it is common to assume a functional form for the Galactocentric distribution of SNRs. However, several functional forms have been used in the past, without much justification for the radial distribution. For example, one often used functional form implies that no supernova activity is present in the Galactic Centre region. However, the presence of a magnetar and a SNR near the Galactic Centre suggest that a spatial distribution with zero SNRs at the Galactic Centre is not realistic. In light of these concerns we reevaluate the Galactic SNR distribution. We provide a brief outline of the main detection biases in finding SNRs and we investigate whether or not the use of the most common functional form is justified and how it compares to other models for the SNR distribution. We do this by analysing the longitudinal distribution of SNRs. We find that a simple exponential distribution is the most consistent and simplest model for describing the radial SNR distribution in the Galaxy and draw comparisons with the massive star formation and metallicity distributions.

description: We investigate correlations of current at contacts and voltage fluctuations at voltage probes coupled to interferometers. The results are compared with correlations of current and occupation number fluctuations at dephasing probes. We use a quantum Langevin approach for the average quantities and their fluctuations. For higher order correlations we develop a stochastic path integral approach and find the generating functions of voltage or occupation number fluctuations. We also derive a generating function for the joint distribution of voltage or occupation number at the probe and current fluctuations at a terminal of a conductor. For energy independent scattering we found earlier that the generating function of current cumulants in interferometers with a one-channel dephasing or voltage probe are identical. Nevertheless, the distribution function for voltage and the distribution function for occupation number fluctuations differ, the latter being broader than that of former in all examples considered here.

description: A natural consequence of string theory is a non-commutative structure of space-time on microscopic scales. The existence of a minimal length, and a modification of the effective field theory are two consequences of this space-time non-commutativity. I will first explore some consequences of the modifications of the effective field theory for structure formation in the context of an inflationary cosmology. Then, I will explore the possibility that the existence of a minimal length will lead to a structure formation scenario different from inflation. Specifically, I will discuss recent work on string gas cosmology.

description: We present AGGGEN (pronounced 'again'), a data-to-text model which re-introduces two explicit sentence planning stages into neural data-to-text systems: input ordering and input aggregation. In contrast to previous work using sentence planning, our model is still end-to-end: AGGGEN performs sentence planning at the same time as generating text by learning latent alignments (via semantic facts) between input representation and target text. Experiments on the WebNLG and E2E challenge data show that by using fact-based alignments our approach is more interpretable, expressive, robust to noise, and easier to control, while retaining the advantages of end-to-end systems in terms of fluency. Our code is available at https://github.com/XinnuoXu/AggGen.

description: Purpose: In this study, we examine joint engagement (JE) in young children with fragile X syndrome (FXS) and its relationship to language abilities and autism spectrum disorder symptomatology at 24 to 36 months (toddler period) and 59 to 68 months (child period). Method: Participants were 28 children with FXS (24 boys, four girls) and their mothers. Videotaped home observations were conducted during the toddler period and coded for JE. Language abilities were measured at both ages from a developmental assessment, a functional measure, and from a language sample. The Childhood Autism Rating Scale (Schopler, Reichler, & Renner, 1988) was completed at both ages. Results: Children with FXS spent more time in supported JE than in coordinated JE. Using a weighted JE variable, we found that children with FXS who had higher weighted JE scores also had more advanced expressive language skills at both the toddler and child periods. Weighted JE was negatively related to autism symptomatology in the toddler period. Conclusion: This study provides evidence that children with FXS who use more JE also have more advanced expressive language skills in early development. Therefore, existing early interventions that target JE behaviors may be effective for promoting language, social communication, and social interaction in this population.

description: Am 9.12.1603 beschwerte sich die Hamburger Bürgerschaft gegenüber dem Rat, dass sich unter den Portugiesen in der Hansestadt auch Juden befänden. Die Bürger erkennen in ihrer Beschwerde zwar den wirtschaftlichen Nutzen der portugiesischen Kaufleute für die Stadt an, verlangen aber die Ausweisung all der Portugiesen, die sich lediglich als Christen ausgeben und insgeheim die jüdische Religion praktizieren. Die Bürgerschaft wurde in ihrer Ablehnung von Juden in der Hansestadt durch die lutherisch-orthodoxe Geistlichkeit unterstützt. Der Rat hatte hingegen das Ziel, den lukrativen Handel mit der Iberischen Halbinsel zu stärken. Dabei wollte er von den Kontakten der Portugiesen profitieren – unabhängig davon, ob diese katholisch oder jüdisch waren. Die Situation der portugiesischen Juden in Hamburg änderte sich so im 17. Jahrhundert mehrfach und war davon abhängig, welche Seite sich in der jeweiligen Auseinandersetzung durchsetzen konnte. Die Beschwerde aus dem Jahr 1603 ist die erste offizielle Erwähnung einer jüdischen Präsenz im Protokoll der Hamburger Obrigkeiten. Sie ist im Protokoll des Konvents zwischen Bürgerschaft und Rat überliefert, das sich heute im Hamburger Staatsarchiv befindet.

description: On December 9, 1603, the Hamburg Parliament lodged a complaint with the Executive Council, that among the Portuguese in the Hansa city Jews were also to be found. The burgesses, to be sure, acknowledged in their complaint the economic utility of the Portuguese merchants for the city, but nonetheless demanded the expulsion of all Portuguese who gave out that they were Christians but who secretly practiced the Jewish religion. In its rejection of Jews in the Hansa city, the Parliament was supported by the orthodox Lutheran clergy. The Executive Council, on the contrary, pursued the goal of strengthening the lucrative trade with the Iberian Peninsula. To this end, the Council wanted to profit from Portuguese contacts--independent of whether they were Catholic or Jewish. The situation of the Portuguese Jews changed several times during the 17th century and in this regard was dependent on which side was able to get its way in the current dispute. The complaint from the year 1603 is the first official mention of a Jewish presence in the minutes of the Hamburg authorities. It is preserved in the minutes of the caucus between the Parliament and the Executive Council, which today is held in the Hamburg State Archive.

description: Current Graph Neural Networks (GNNs) suffer from the over-smoothing problem, which results in indistinguishable node representations and low model performance with more GNN layers. Many methods have been put forward to tackle this problem in recent years. However, existing tackling over-smoothing methods emphasize model performance and neglect the over-smoothness of node representations. Additional, different approaches are applied one at a time, while there lacks an overall framework to jointly leverage multiple solutions to the over-smoothing challenge. To solve these problems, we propose GraTO, a framework based on neural architecture search to automatically search for GNNs architecture. GraTO adopts a novel loss function to facilitate striking a balance between model performance and representation smoothness. In addition to existing methods, our search space also includes DropAttribute, a novel scheme for alleviating the over-smoothing challenge, to fully leverage diverse solutions. We conduct extensive experiments on six real-world datasets to evaluate GraTo, which demonstrates that GraTo outperforms baselines in the over-smoothing metrics and achieves competitive performance in accuracy. GraTO is especially effective and robust with increasing numbers of GNN layers. Further experiments bear out the quality of node representations learned with GraTO and the effectiveness of model architecture. We make cide of GraTo available at Github (\url{https://github.com/fxsxjtu/GraTO}).

Maximizing the expression of a cloned gene under the regulation of the metallothionein promoter
Creators: name: Jervis, Eric J
Publisher: name: University of British Columbia
Year: 2008

description: A stably transformed BHK cell line, engineered to produce a human transferrin half-molecule under the control of a mouse metallothionein promoter, was used as a model system to develop strategies to maximize recombinant protein productivity in mammalian cell culture. The metallothionein promoter is inducible and promotes high levels of expression. Fully induced cells produced up to 0.7 pg transferrin/cell hr, a 4-fold increase in transferrin production over uninduced levels. Cell growth was inhibited at cadmium dosages above 1.0 fmole/cell; prolonged exposure at this dosage is cytotoxic. The metal dose-dependence of induction and lethal effects at high metal dosages motivated the development of special strategies to maximize gene expression. Dosing regimes which maintained cell associated cadmium concentrations below 0.25 fmole/cell, ensured cell growth and high cell specific productivities which maximized final product titers. For routine batch culture initial inducer loadings of 10 fmole/cell for zinc and 1.0 fmole/cell for cadmium gave near-maximum transferrin production levels. For extended culture, repeated small doses of between 0.25 fmole/cell and 0.45 fmole/cell, based on initial cell counts, every 48 hours maximized transferrin synthesis with this cell line. A novel compartmental model with 3 inducer pools was developed which quantitatively reproduced many of the experimental results. Dose-dependent compartmental transfer functions were modeled and kinetic parameters estimated for transferrin synthesis and secretion. Several batch and fedbatch inducer dosing strategies were simulated to identify protocols which maximized gene expression. Sensitivity analysis of the model's parameters predicted that transferrin production rates are less sensitive to variation in cell specific cadmium uptake rates at lower inducer loadings.

description: We analyze lepton flavour violation (LFV), as well as generation of the observed baryon-antibaryon asymmetry of the Universe (BAU) within a generalized minimal lepton flavour violation (MLFV) framework where we allow for CP violation both at low and high energies. The generation of BAU is obtained through radiative resonant leptogenesis (RRL), where starting with three exactly degenerate right-handed neutrinos at Lambda_GUT, we demonstrate explicitly within the SM and the MSSM that the splittings between their masses at the see-saw scale M_nu, generated by renormalization group effects, are sufficient for a successful leptogenesis for M_nu even as low as 10^6 GeV. The inclusion of flavour effects plays an important role in this result and can lead to the observed BAU even in the absence of CP violation beyond the PMNS phases. The absence of a stringent lower bound on M_nu in this type of leptogenesis allows to easily satisfy present and near future upper bounds on mu -> e gamma and other charged lepton flavour violating (LFV) processes even for Lambda_LFV = O(1 TeV). We find, that the MLFV framework in the presence of heavy right-handed neutrinos and leptogenesis is not as predictive as MFV in the quark sector and point out that without a specific MLFV model, there is a rich spectrum of possibilities for charged LFV processes and for their correlation with low energy neutrino physics and the LHC physics, even if the constraint from the observed BAU is taken into account. While certain qualitative features of our analysis confirm findings of Cirigliano et al., at the quantitative level we find phenomenologically important differences. We explain the origin of these differences.

description: This study explores the ways by which the current politics, the ideology and the institutions of the demographic city-state of Athens affect the suppliants of Aeschylus. The study uses the traditional method of finding political allusions, but exploits also modern methods inspired from anthropology, ethnology, imagined geography as an allegory that comments on the relations of Athens with its Ionian allies, based on the constant identification between the Danaids and Ioanians. The identification of Pelasgian Argives with the Athenians is accomplished with references to the autochthonous, pelasgic nature of the people of Argos. These themes were key elements of the Athenian ideology during the 5th century

description: We investigate an interpolation/extrapolation method that, given scattered observations of the Fourier transform, approximates its inverse. The interpolation algorithm takes advantage of modelling the available data via a shape-driven interpolation based on Variably Scaled Kernels (VSKs), whose implementation is here tailored for inverse problems. The so-constructed interpolants are used as inputs for a standard iterative inversion scheme. After providing theoretical results concerning the spectrum of the VSK collocation matrix, we test the method on astrophysical imaging benchmarks.
3.9 day orbital modulation in the TeV gamma-ray flux and spectrum from the X-ray binary LS 5039

description: New observations of LS 5039, a High Mass X-ray Binary comprising a massive star and compact object, were carried out with the High Energy Stereoscopic System of Cherenkov Telescopes (H.E.S.S.) in 2005 at very high energy (VHE) gamma-ray energies. These observations reveal that its flux and energy spectrum are modulated with the 3.9 day orbital period of the binary system. This is the first time in gamma-ray astronomy that orbital modulation has been observed, and periodicity clearly established using ground-based gamma-ray detectors. The VHE gamma-ray emission is largely confined to half of the orbit, peaking around the inferior conjunction epoch of the compact object. For this epoch, there is also a hardening of the energy spectrum in the energy range between 0.2 TeV and a few TeV. The flux vs. orbital phase profile provides the first clear indication of gamma-ray absorption via pair production within an astrophysical source, a process which is expected to occur if the gamma-ray production site is situated within ~1 AU of the compact object. Moreover the production region size must be not significantly greater than the binary separation (~0.15 AU). Notably, these constraints are also considerably smaller than the collimated outflows or jets (extending out to ~1000 AU) observed in LS 5039. The spectral hardening could arise from variations with phase in the maximum electron energies, and/or the dominant VHE gamma-ray production mechanism.

description: Progress on two-dimensional materials has shown that valleys, as energy extrema in a hexagonal first Brillouin zone, provides a new degree of freedom for information manipulation. Then valley Hall topological insulators supporting such-polarized edge states on boundaries were set up accordingly. In this paper, a two-dimensional valley photonic crystal composed of six tunable dielectric triangular pillars in unit cells is proposed in the photonic sense of a deformed Su-Schrieffer-Heeger (SSH) model. We reveal the vortex nature of valley states and establish the selection rules for valley polarized states. Based on the valley topology, a rhombus-shaped beam splitter waveguide is designed to verify the valley-chirality selection above. Our numerical results entail that this topologically protected edge states still maintain robust transmission at sharp corners, henceforth providing a feasible idea for valley photonic devices in THz regime.

description: The solar photosphere and the outer layer of the Sun's interior are characterized by convective motions, which display a chaotic and turbulent character. In this work, we evaluated the pseudo-Lyapunov exponents of the overshooting convective motions observed on the Sun's surface by using a method employed in the literature to estimate those exponents, as well as another technique deduced from their definition. We analyzed observations taken with state-of-the-art instruments at ground- and space-based telescopes, and we particularly benefited from the spectro-polarimetric data acquired with the Interferometric Bidimensional Spectrometer, the Crisp Imaging SpectroPolarimeter, and the Helioseismic and Magnetic Imager. Following previous studies in the literature, we computed maps of four quantities which were representative of the physical properties of solar plasma in each observation, and estimated the pseudo-Lyapunov exponents from the residuals between the values of the quantities computed at any point in the map and the mean of values over the whole map. In contrast to previous results reported in the literature, we found that the computed exponents hold negative values, which are typical of a dissipative regime, for all the quantities derived from our observations. The values of the estimated exponents increase with the spatial resolution of the data and are almost unaffected by small concentrations of magnetic field. Finally, we showed that similar results were also achieved by estimating the exponents from residuals between the values at each point in maps derived from observations taken at different times. The latter estimation technique better accounts for the definition of these exponents than the method employed in previous studies.

description: Collective decays of multiply-excited atoms become subradiant and bound in space when they are strongly coupled to the guided modes in an atom-waveguide interface. In this interface, we analyze their average density-density and modified third-order correlations via Kubo cumulant expansions, which can arise and sustain for long time. The shape-preserving dimers and trimers of atomic excitations emerge in the most subradiant coupling regime of light-induced dipole-dipole interactions. This leads to a potential application of quantum information processing and quantum storage in the encoded nonreciprocal spin diffusion, where its diffusion speed depends on the initial coherence between the excited atoms and is robust to their relative phase fluctuations. The state-dependent photon routing can be viable as well in this interface.

description: This letter reports on the Galactic stellar structures that appear in the foreground of our Canada-France-Hawaii-Telecopse/MegaCam survey of the halo of the Andromeda galaxy. We recover the main sequence and main sequence turn-off of the Triangulum-Andromeda structure recently found by Majewski and collaborators at a heliocentric distance of ~20 kpc. The survey also reveals another less populated main sequence at fainter magnitudes that could correspond to a more distant stellar structure at ~28 kpc. Both structures are smoothly distributed over the ~76 sq. deg. covered by the survey although the closer one shows an increase in density by a factor of ~2 towards the North-West. The discovery of a stellar structure behind the Triangulum-Andromeda structure that itself appears behind the low-latitude stream that surrounds the Galactic disk gives further evidence that the inner halo of the Milky Way is of a spatially clumpy nature.

description: LYSO scintillation crystals, due to their significant characteristics such as high light yield, fast decay time, small Moliére radius, and good radiation hardness, are proposed to be used for the electromagnetic calorimeter section of the Turkish Accelerator Center Particle Factory (TAC-PF) detector. In this work, the center of gravity technique was used to determine the impact coordinates of an electron initiating an electromagnetic shower in the LYSO array, the calorimeter module contains nine crystals, each 25 mm$\times$25 mm in cross-section and 200 mm in length. The response of the calorimeter module has been studied with electrons having energies in the range 0.1 GeV-2 GeV. By using the Monte Carlo simulation based on Geant4, the two-dimensional position resolution of the module is obtained as $σ_{R}(mm)=((3.95\pm0.08)/\sqrt{E})\oplus(1.91\pm0.11)$ at the center of the crystal.

description: It is shown that the fine stucture of the cosmic ray energy spectrum in the knee region, if explained by the Single Source Model (SSM), can, in principle, be clearly revealed and magnified in the size spectrum of extensive air showers (EAS) associated with gamma families. Existing experimental data on EAS at mountain level give support to this hypothesis.

Dynamo Action in the Solar Convection Zone and Tachocline: Pumping and Organization of Toroidal Fields

description: We present the first results from three-dimensional spherical shell simulations of magnetic dynamo action realized by turbulent convection penetrating downward into a tachocline of rotational shear. This permits us to assess several dynamical elements believed to be crucial to the operation of the solar global dynamo, variously involving differential rotation resulting from convection, magnetic pumping, and amplification of fields by stretching within the tachocline. The simulations reveal that strong axisymmetric toroidal magnetic fields (about 3000 G in strength) are realized within the lower stable layer, unlike in the convection zone where fluctuating fields are predominant. The toroidal fields in the stable layer possess a striking persistent antisymmetric parity, with fields in the northern hemisphere largely of opposite polarity to those in the southern hemisphere. The associated mean poloidal magnetic fields there have a clear dipolar geometry, but we have not yet observed any distinctive reversals or latitudinal propagation. The presence of these deep magnetic fields appears to stabilize the sense of mean fields produced by vigorous dynamo action in the bulk of the convection zone.

description: Spectroscopic observations at extreme and far ultraviolet wavelengths have revealed systematic upflows in the solar transition region and corona. These upflows are best seen in the network structures of the quiet Sun and coronal holes, boundaries of active regions, and dimming regions associated with coronal mass ejections. They have been intensively studied in the past two decades because they are highly likely to be closely related to the formation of the solar wind and heating of the upper solar atmosphere. We present an overview of the characteristics of these upflows, introduce their possible formation mechanisms, and discuss their potential roles in the mass and energy transport in the solar atmosphere. Though past investigations have greatly improved our understanding of these upflows, they have left us with several outstanding questions and unresolved issues that should be addressed in the future. New observations from the Solar Orbiter mission, the Daniel K. Inouye Solar Telescope and the Parker Solar Probe will likely provide critical information to advance our understanding of the generation, propagation and energization of these upflows.

Dissipative soliton interaction in Kerr resonators with high-order dispersion

description: We consider an optical resonator containing a photonic crystal fiber and driven coherently by an injected beam. This device is described by a generalized Lugiato-Lefever equation with fourth order dispersion. We use an asymptotic approach to derive interaction equations governing the slow time evolution of the coordinates of two interacting dissipative solitons. We show that Cherenkov radiation induced by positive fourth-order dispersion leads to a strong increase of the interaction force between the solitons. As a consequence, large number of equidistant soliton bound states in the phase space of the interaction equations can be stabilized. We show that the presence of even small spectral filtering not only dampens the Cherenkov radiation at the soliton tails and reduces the interaction strength, but can also affect the the bound state stability.

Spouted bed hydrodynamics at temperatures up to 580 C
Creators: name: Li, Yang
Publisher: name: University of British Columbia
Year: 2008

description: A study of the hydrodynamics of spouted beds at temperatures ranging from room temperature to 580°C was carried out using a 0.156 m I.D. stainless steel conical-cylindrical half-column. Five narrowly sized fractions of Target sand with reciprocal mean diameters of 0.915 mm, 1.010 mm, 1.200 mm, 1.630 mm and 2.025 mm, and three orifices with internal diameters of 12.70 mm, 19.05 mm and 26.64 mm were used. The main purpose of the present work was to obtain a wide range of experimental data at high temperatures and compare the results with existing equations, to establish new correlations under different circumstances. Aspects studied included minimum spouting velocity, Ums, maximum spoutable bed height, Hm, and average spout diameter, Ds. It was found that the stability of spouting decreased with increasing temperature. The value of Ums increased with increasing temperature, especially for the large particles. The best of several empirical equations developed for Ums is one which uses the free-settling terminal velocity of the particles as a correlating parameter. The McNab - Bridgwater equation for Hm overpredicted Hm substantially at room temperatures and underpredicted Hm slightly at high temperatures. A similar equation with a slightly smaller value of Um/Umf than that recommended by McNab and Bridgwater gives better overall results. The Wu et al. non-dimensional equation for Ds, which explicitly includes the effect of gas density and gas viscosity, hence of gas temperature, gave better absolute prediction of the average spout diameter, Ds, than did the dimensional McNab equation, especially at elevated bed temperatures.
Light Nuclei in the Framework of the Symplectic No-core Shell Model

description: A symplectic no-core shell model (Sp-NCSM) is constructed with the goal of extending the {\it ab-initio} NCSM to include strongly deformed higher-oscillator-shell configurations and to reach heavier nuclei that cannot be studied currently because the spaces encountered are too large to handle, even with the best of modern-day computers. This goal is achieved by integrating two powerful concepts: the {\it ab-initio} NCSM with that of the $\mathrm{Sp}(3,\mathbb{R})\supset\mathrm{SU}(3)$ group-theoretical approach. The NCSM uses modern realistic nuclear interactions in model spaces that consists of many-body configurations up to a given number of $\hbarΩ$ excitations together with modern high-performance parallel computing techniques. The symplectic theory extends this picture by recognizing that when deformed configurations dominate, which they often do, the model space can be better selected so less relevant low-lying $\hbarΩ$ configurations yield to more relevant high-lying $\hbarΩ$ configurations, ones that respect a near symplectic symmetry found in the Hamiltonian. Results from an application of the Sp-NCSM to light nuclei are compared with those for the NCSM and with experiment.

Affine perturbation series of the deflection angle of a ray near the photon sphere of a Reissner-Nordström black hole

description: We investigate the affine perturbation series of the deflection angle of a ray near the photon sphere of an extreme Reissner-Nordström black hole. We compare the 0th and 1st orders of the affine perturbation series with the deflection angle in a strong deflection limit. We conclude that the 0th order of the affine perturbation series is more accurate than the deflection angle in the strong deflection limit and that we should improve a strong-deflection-limit analysis by using the 0th order of the affine perturbation series.
