Nonlinear Impedance Spectroscopy and Its Application to Solid Oxide Fuel Cells
Creators: name: Xu, Ning
Publisher: name: Imperial College London
Year: 2013

description: Electrochemical impedance spectroscopy (EIS) is recognized as a powerful tool for characterizing the charge transfer reaction on heterogeneous interfaces, thus has been widely applied in various fields of research and in many applications, such as corrosion, development of various types of batteries and fuel cells. Due to the limitation of linearization inherent to the EIS technique the nonlinear information of an investigated system is automatically abandoned. This work focuses on extending the traditional linear EIS technique into the nonlinear domain, nonlinear EIS (NLEIS), and has demonstrated that the nonlinear information can be utilized for gaining a more comprehensive understanding of a system. In this work, the NLEIS technique is discussed from a basic theoretical point of view, including the fundamental definition of nonlinear “impedance” and experimental issues on which a consensus has yet to be reached within the community. A LabView programmed experimental setup was developed during the project to perform NLEIS measurements and preliminary data analysis, which appeared superior to commercial systems (higher frequency range) and systems developed at other institutes (lower noise level). A qualitative approach for data analysis in NLEIS is discussed and prompted in this work, which is more intuitive and suitable for fast first stage analysis compared to an in-depth quantitative modelling approach. To test the NLEIS methodology developed, a classic redox couple- ferri-ferrocyanide- was examined. Information on nonlinearity and symmetry of the system was directly investigated by measuring harmonic responses up to 5th order and it was demonstrated that in contrast to EIS a full set of kinetic parameters could be directly calculated from a single measurement. In addition, features generic to the methodology were discovered, which are independent of systems under investigation. Finally, the NLEIS technique was used in investigating the oxygen reduction reaction on strontium and iron doped lanthanum cobaltite (LSCF) cathode materials of intermediate-temperature solid oxide fuel cells (IT-SOFCs). The decrease of the level of nonlinearity and the increase of asymmetry indicates a potential mechanism change, with increased operating temperature.

description: We analyze the role of the surface terms in the conservation law for the sum of the magnetic helicity density and the chiral imbalance of the charged particle densities. These terms are neglected in the Anomalous MagnetoHydroDynamics (AMHD), where infinite volume is considered typically. We discuss a finite volume system, such as a magnetized neutron star (NS), and study the contribution of the surface terms to the evolution of the magnetic helicity. Accounting for the fast washing out of the chiral imbalance in a nascent NS, we demonstrate that the surface terms contribution can potentially lead to the reconnection of magnetic field lines and subsequent gamma or X-ray bursts observed from magnetars. We derive the additional surface terms originated by the mean spin flux through a volume boundary arising due to macroscopic spin effects in electron-positron plasma. Then, comparing this quantum surface term with the classical one known in standard MHD, we find that the new quantum contribution prevails over classical term for the rigid NS rotation only.

description: Redshift Survey Compact Groups (RSCGs) are tight knots of N >= 3 galaxies selected from the CfA2+SSRS2 redshift survey. The selection is based on physical extent and association in redshift space alone. We measured 300 new redshifts of fainter galaxies within 1 h^{-1} Mpc of 14 RSCGs to explore the relationship between RSCGs and their environments. 13 of 14 RSCGs are embedded in overdense regions of redshift space. The systems range from a loose group of 5 members to an Abell cluster. The remaining group, RSCG 64, appears isolated. RSCGs are isolated and distinct from their surroundings to varying degrees, as are the Hickson Compact Groups. Among the 13 embedded RSCGs, 3 are distinct from their general environments (RSCG 9, RSCG 11 and RSCG 85).

description: In the recent years experiments have established the existence of neutrino oscillations and most of the oscillation parameters have been measured with a good accuracy. The search for New Physics in neutrino oscillation will be an experimental concrete possibility in the next future. In this paper we investigate the ability of the DUNE facility to search for Non Standard Interaction (NSI) in neutrino propagation in matter, emphasizing the role of different assumptions on the shape and absolute normalization errors of both $ν_e$ and $ν_μ$ signals. We also study in detail the effects of NSI and systematics in the extraction of standard oscillation parameters.

The Mild Synthesis of Zinc Oxide Nanoparticles and Nanocomposites via hydrolysis of Well-Characterised Zinc Organometallics
Creators: name: Orchard, Katherine Lorraine
Publisher: name: Imperial College London
Year: 2011

description: This thesis centres on the development of a clean, one step method for generating surface-functionalised zinc oxide (ZnO) nanoparticles for application in the synthesis of well-dispersed inorganic-organic nanocomposites. The nanoparticle synthesis method utilises the controlled hydrolysis of organometallic zinc compounds, employing diethylzinc as a bulk precursor and an alkylzinc carboxylate as a substoichiometric, secondary precursor to deliver the capping ligands. A series of ethylzinc carboxylate species were synthesised and studied by NMR spectroscopy (EtZn(OOCR); R = H, CH3, and (CH2)nCH3, where n = 4, 10, 16). The ligand stoichiometry of the complexes was found to depend on the nature of the solvent (coordinating vs. non-coordinating), and single crystal X-ray experiments indicated that the strength of the donor interaction of a coordinating solvent affects the nuclearity of the complex‟s repeat unit in the solid state. In addition, the isolated complexes of the acetate derivative were active catalysts for the copolymerisation of CO2 and cyclohexene oxide. The ZnO nanoparticle synthesis route was first explored in the absence of a polymer matrix and was proven to yield hydrophobic nanoparticles with a narrow size distribution without the need for size selection steps (average particle size 3.6 ± 0.2 nm, σ = 15% using stearate; HR-TEM). The effect of varying different synthesis parameters on the resulting ZnO particle size and morphology was investigated. Additional inorganic zinc phases were observed on slowing the reaction rate, allowing insight into the mechanism of delivery of carboxylate groups to the growing nanoparticle surfaces. Finally, in situ ZnO/epoxy resin nanocomposites were prepared. The degree of nanoparticle dispersion improved with surface-functionalisation in the order stearate < uncapped < benzoate (TEM), which correlated with the nature of the particle-matrix interaction (DSC). In situ prepared nanoparticles (uncapped) were also introduced into conventional microcomposites and found to improve the composite density and thermal conductivity relative to the highest loading of microparticles alone.

description: We describe a version of an algorithm for evolving self-gravitating collections of particles that should be nearly ideal for parallel architectures. Our method is derived from the ``self-consistent field'' (SCF) approach suggested previously by Clutton-Brock and others. Owing to the use of a global description of the gravitational field, the particles in an SCF simulation do not interact with one another directly, minimizing communications overhead between nodes in a parallel implementation. Ideal load-balancing is achieved since precisely the same number of operations are needed to compute the acceleration for each particle. Consequently, the SCF technique is perfectly scalable and the size of feasible applications will grow in simple proportion to advances in computational hardware. We describe an SCF code developed for and tested on a Connection Machine 5. Empirical tests demonstrate the efficient and scalable nature of the algorithm. Depending on the application, simulations with particle numbers in the range $N\sim 10^7 - 10^{8.5}$ are now possible. Larger platforms should make simulations with billions of particles feasible in the near future. Specific astrophysical applications are discussed in the context of collisionless dynamics.

description: In this article we give the details on the analytic calculation of the master integrals for the planar double box integral relevant to top-pair production with a closed top loop. We show that these integrals can be computed systematically to all order in the dimensional regularisation parameter $\varepsilon$. This is done by transforming the system of differential equations into a form linear in $\varepsilon$, where the $\varepsilon^0$-part is a strictly lower triangular matrix. Explicit results in terms of iterated integrals are presented for the terms relevant to NNLO calculations.

Circulating microRNA in Chronic Obstructive Pulmonary Disease
Creators: name: Donaldson, Anna
Publisher: name: Imperial College London
Year: 2014

description: Skeletal muscle dysfunction in COPD is associated with increased morbidity. Novel agents might reverse skeletal muscle dysfunction through different mechanisms since the biopsy picture in COPD patients is heterogenous. Thus there is a need for a biomarker of skeletal muscle dysfunction which could both be measured in blood and obviate the need for a biopsy. Previous work has found that muscle-specific microRNA (miR-1, miR-499, miR-206 and miR-133) are down-regulated in the quadriceps of COPD patients. Tissue specific miRNA circulate in the blood at detectable levels and are currently under investigation as biomarkers of other diseases. I therefore hypothesised that muscle-specific microRNA might be clinically viable biomarkers of skeletal muscle dysfunction. The studies in this thesis found that: 1. Levels of circulating muscle-specific microRNA (miR-1, miR-133, miR-206 and miR-499) were increased in stable COPD patients. The increase in muscle-specific microRNA in the stable COPD patients suggests that continual muscle turnover occurs outside of times of disease exacerbation. 2. Plasma levels of muscle-specific miRNA were not different in COPD patients admitted to hospital for an exacerbation of their disease compared to stable COPD patients. 3. Most muscle-specific microRNA did not change in muscle with acute exercise. I demonstrated an increase in miR-181 (an miRNA not restricted to, but with known function in muscle) one hour after acute exercise in the quadriceps muscle of COPD patients. However when fold change was calculated for the COPD patients and controls, there was no statistical difference found. There were no detectable miR-181 changes measured in blood. 4. Finally, I used a microarray approach to investigate other circulating microRNA that might to be useful to separate patients based on their lean muscle-mass. COPD patients with a reduced skeletal muscle mass had a reduced number of microRNA associated with growth and cell pluripotency, further studies are required to validate these findings. Taken together, the results from this thesis suggest that the microRNA analysed were detectable in blood, but they could not be usefully used (based on current analysis) as biomarkers of quadriceps dysfunction.
Surface Brightness of Starbursts at Low and High Redshifts

description: Observations in the rest frame ultraviolet from various space missions are used to define the nearby starburst regions having the highest surface brightness on scales of several hundred pc. The bright limit is found to be 6x10^-16 ergs/cm^2-s-A-arcsec^2 for rest frame wavelength of 1830 A. Surface brightness in the brightest pixel is measured for 18 galaxies in the Hubble Deep Field having z > 2.2. After correcting for cosmological dimming, we find that the high redshift starbursts have intrinsic ultraviolet surface brightness that is typically four times brighter than low redshift starbursts. It is not possible to conclude whether this difference is caused by decreased dust obscuration in the high redshift starburst regions or by intrinsically more intense star formation. Surface brightness enhancement of starburst regions may be the primary factor for explaining the observed increase with redshift of the ultraviolet luminosity arising from star formation.

Searches for neutral Higgs bosons in the tau tau final state at CMS
Creators: name: Lane, Rebecca
Publisher: name: Imperial College London
Year: 2015

description: The Compact Muon Solenoid (CMS) detector is located at the CERN Large Hadron Collider. It is a general purpose detector designed to test predictions of the standard model (SM) and search for the Higgs boson, as well as to look for signatures of new physics beyond the SM. The analyses described in this thesis use proton-proton collision data recorded by CMS during 2011 and 2012. Searches for neutral Higgs bosons decaying into tau pairs are presented. The searches are performed separately for the SM Higgs boson or the neutral Higgs bosons of the minimal supersymmetric standard model (MSSM). The MSSM searches consist of two different analyses. The first is a direct search for any one of the MSSM neutral Higgs bosons in the mass range from 90 GeV to 1 TeV decaying directly into taus. The second searches for the signature from a heavy neutral Higgs boson of the MSSM decaying into two light MSSM Higgs bosons with SM-like properties (H → hh) in the final state with two b-quarks and two taus. The SM and MSSM ττ analyses use 4.9 fb−1 of data collected at 7 TeV and 19.7 fb−1 collected at 8 TeV, while the MSSM H → hh analysis uses only the 8 TeV data. In the SM analysis, an excess of events in data above the background expectation is observed with an observed (expected) local significance of 3.2 (3.7) standard deviations at 125 GeV. This excess is found to be consistent with the 125GeV Higgs boson of the SM in mass and coupling strengths. No significant excess is observed in either MSSM search, and so upper limits are set on cross-section times branching ratio for the Higgs production processes at the 95% confidence level. Limits are also set in mA-tanβ parameter space of several interesting MSSM benchmark scenarios.

description: HST observations of eight intrinsically luminous quasars with redshifts between $0.16$ and~$0.29$ are presented. Seven companion galaxies brighter than $M_V = -16.5$ lie within a projected distance of 25 kpc of the quasars; three of the companions are located closer than $3''$ (6 kpc projected distance) from the quasars, well within the volume that would be enclosed by a typical $L^*$ host galaxy. The observed association of quasars and companion galaxies is statistically significant and may be an important element in the luminous-quasar phenomenon. Evidence for candidate host galaxies is presented for the three most promising cases: PG 1116+215, 3C 273, and PG 1444+407, but additional observations are required before the characteristics of the candidate hosts can be regarded as established. Upper limits are placed on the visual-band brightnesses of representative galactic hosts for all of the quasars. These limits are established by placing galaxy images obtained with HST underneath the quasars and measuring at what faintness level the known galaxies are detected. On average, the HST spirals would have been detected if they were one magnitude fainter than $L^*$ or brighter and the early-type galaxies could have been detected down to a brightness level of about $L^*$, where $L^*$ is the Schechter characteristic luminosity of field galaxies.

Detailed Mid- and Far-Ultraviolet Model Spectra for Accretion Disks in Cataclysmic Binaries

description: We present a large grid of computed far- and mid-ultraviolet spectra (850 Angstroms to 2000 Angstroms) of the integrated light from steady-state accretion disks in luminous cataclysmic variables. The spectra are tabulated at 0.25 Angstrom intervals with an adopted FWHM resolution of 1.0 Angstrom, so they are suitable for use with observed spectra from a variety of modern space-borne observatories. Twenty-six different combinations of white dwarf mass M(wd) and mass accretion rate dM/dt are considered, and spectra are presented for six different disk inclinations, i. The disk models are computed self-consistently in the plane-parallel approximation, assuming LTE and vertical hydrostatic equilibrium, by solving simultaneously the radiative transfer, hydrostatic equilibrium, and energy balance equations. Irradiation from external sources is neglected. Local spectra of disk annuli are computed taking into account line transitions from elements 1-28 (H through Ni). Limb darkening as well as Doppler broadening and blending of lines are taken into account in computing the integrated disk spectra. The radiative properties of the models are discussed, including the dependence of ultraviolet fluxes and colors on M(wd), dM/dt, and i. The appearance of the disk spectra is illustrated, with regard to changes in the same three parameters. Finally, possible future improvements to the present models and spectra are discussed. The synthetic spectra are available as machine-readable ASCII files via ftp.

Terrestrial Implications of Cosmological Gamma-Ray Burst Models

description: The observation by the BATSE instrument on the Compton Gamma Ray Observatory that gamma-ray bursts (GRBs) are distributed isotropically around the Earth but nonuniformly in distance has led to the widespread conclusion that GRBs are most likely to be at cosmological distances, making them the most luminous sources known in the Universe. If bursts arise from events that occur in normal galaxies, such as neutron star binary inspirals, then they will also occur in our Galaxy about every hundred thousand to million years. The gamma-ray flux at the Earth due to a Galactic GRB would far exceed that from even the largest solar flares. The absorption of this radiation in the atmosphere would substantially increase the stratospheric nitric oxide concentration through photodissociation of N$_2$, greatly reducing the ozone concentration for several years through NO$_x$ catalysis, with important biospheric effects due to increased solar ultraviolet flux. A nearby GRB may also leave traces in anomalous radionuclide abundances.

The role of deep moist convective processes in western boundary currents - troposphere coupling
Creators: name: Sheldon, Luke
Publisher: name: Imperial College London
Year: 2014

description: Previous studies have suggested that atmospheric deep convection is occurring above the oceans western boundary currents. To investigate the occurrence of deep (ocean surface to troposphere) convection in mid-latitudes, diagnostics of upright and slantwise convective instability are created and used in the ERA-interim re-analysis dataset. These diagnostics find that deep convection is restricted to the western boundary currents in winter. However, over the ocean currents deep convection can occur up to 50% of the winter. As these ocean currents, including the Gulf Stream and Kuroshio, are warm and carry large quantities of heat polewards they could influence the frequency of deep convection. A simple calculation demonstrates that decadal ocean variability can change the atmospheric stability by 80% in the core of the Kuroshio and Gulf Stream. The deep convective instability occurs in synoptic systems that pass over the ocean currents. Specifically, instability occurs on the atmospheric fronts in the extra-tropical cyclones. To investigate the convective instability and related circulation at atmospheric fronts a composite of all atmospheric fronts in the Gulf Stream region is produced. The front composites show that where slantwise instability occurred at a front an associated increase in frontal ascent throughout the troposphere and precipitation is also found. An investigation into the possible mechanisms that produced the increased ascent at slantwise unstable fronts concludes that a possible cause is a coarse resolution of slantwise circulations in the ERA-interim dataset. This increase in deep ascent associated with slantwise instability could explain, at least partially, the deep ascent found by previous studies over the Gulf Stream. This is consistent with the finding that the deep ascent in the Gulf Stream annual mean is a product of extreme events. The occurrence of deep slantwise instability and the associated circulations are also resolution dependent. A comparison between 25 km, 60 km and 135 km grid-spacing atmospheric model runs are made using the UPSCALE project dataset. The 25 km model runs indicate greater deep slantwise and upright convective instability. The 25-km set-up is also the only one where increased deep ascent at slantwise unstable fronts is observed.

description: Filter bank multi-carrier (FBMC) offers superior spectral properties compared to cyclic-prefix orthogonal frequency-division multiplexing (CP-OFDM), at the cost of an inherent shortcoming in dispersive channels called intrinsic imaginary interference. In this paper we propose a new FBMC based communication system using two orthogonal polarizations for wireless communication systems: dual-polarization FBMC (DP-FBMC). Using this system we can significantly suppress the FBMC intrinsic interference. Therefore in DP-FBMC all the multicarrier techniques used in CP-OFDM systems such as channel equalization, etc., should be applicable without using the complex processing methods required for conventional FBMC. DP-FBMC also has other interesting advantages over CP-OFDM and FBMC: it is more robust in highly dispersive channels, and also to receiver carrier frequency offset (CFO) and timing offset (TO). In our DP-FBMC system we propose three different structures based on different multiplexing techniques. We show that compared to conventional FBMC, one of these DP-FBMC structures has equivalent complexity and equipment requirements. We compare DP-FBMC with other systems through simulations. According to our results DP-FBMC has potential as a promising candidate for future wireless communication networks.

Sewage sludge as source of activated carbon for the removal of endocrine disrupting chemical in wastewater
Creators: name: Pullket, Suangusa
Publisher: name: Imperial College London
Year: 2015

description: Sewage sludge is an unavoidable consequence of wastewater treatment (WWT). Increasing legislation has propagated sludge production whilst limiting disposal options. WWT effluent contains many trace contaminants, one group of significant concern being endocrine disrupting chemicals (EDCs). Their removal is becoming a priority. Sludge is a potentially valuable material which offers opportunities for reuse and valorisation. This research has undertaken an in depth and rigorous study of the optimization of sludge carbonization and activation to produce inorganic-carbonaceous adsorbents akin to activated carbon. The resulting sludge based adsorbents (SBAs) have been comprehensively evaluated for their adsorption of EDCs using bisphenol A (BPA). This data has enabled a fundamental analysis of SBA-EDC adsorption processes and the proposal of an adsorption mechanism. SBA production using various European sludge types was undertaken, to produce high performance SBAs based on surface area (SA) and EDC adsorption. Key research findings were: • SBAs can be produced from most types of municipal sludge, except lime added sludge. • Carbonized or carbonized/steam activated SBAs presented low SA (270_m2/g) and BPA adsorption capacity (87 mg/g) when compared to chemically activated SBAs. • K2CO3 was the best chemical reagent in producing high SA up to 1979 m2/g and BPA adsorption of 714 mg/g. • FeCl3 is a very attractive chemical reagent in giving high BPA adsorption and SBA yield of 119_mg/g and 59.3_%, respectively. • Bisphenol A adsorption fitted well with Langmuir, Freundlich and Temkin equations with the best fit depending on the production conditions (temperature, time, activating reagent). • BPA adsorption by SBAs generally depend on SA and pore volume, with surface chemistry also influencing adsorption, especially for chemically activated SBAs. • The SBAs produced from K2CO3 activation outperformed all commercial activated carbons (CACs); the best SBA outperformed the best CAC by nearly 2-fold indicating the significant potential of SBAs as effective adsorbents for WWT effluents.
Robust multi-structure segmentation of magnetic resonance brain images
Creators: name: Ledig, Christian
Publisher: name: Imperial College London
Year: 2015

description: Magnetic resonance (MR) imaging is a powerful technique for the non-invasive in-vivo imaging of the human brain. In this thesis several robust techniques are developed that allow the fully-automatic analysis of MR brain images. In particular an approach is presented that quantifies the volume of more than 100 individual structures within the whole brain. This methodology is extended to measure structural volume changes based on images acquired at multiple time points. The possibility to quantify volumetric change of numerous brain structures simultaneously sets the method apart from many established approaches that measure change of individual structures only. The presented methodology is robust in the presence of disease-related atrophy or severe brain deformation. The proposed algorithms are evaluated on widely used reference datasets. The obtained results compare favourable to state-of-the-art techniques. The methods are employed to perform a cross-sectional and a longitudinal analysis of a large cohort of Alzheimer’s disease (AD) patients. Employing the extracted information (volume, atrophy) as features it is shown that AD related disease states can be classified with high accuracy. In addition a prospective cohort of traumatic brain injury (TBI) patients is studied. Structural volumes are extracted at the acute disease stage and the extent of structural change occurring within the months following the head trauma is quantified. The results show that cerebral white matter atrophy is increased in TBI and that the involvement of individual brain structures, such as the hippocampus or the thalamus, is particularly predictive for the outcome of the head injury. These results confirm the methods’ potential to support large scale imaging studies by robustly extracting markers with clinical interpretation from MR brain images. In addition, a novel evaluation measure is proposed to quantitatively assess the accuracy of automatically calculated image segmentations with respect to a reference segmentation.

A CO(3-2) Survey of Nearby Mira Variables
Creators: name: Young, K.
Publisher: name: arXiv
Year: 1995
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: A survey of CO(3-2) emission from optically visible oxygen-rich Mira variable stars within 500 pc of the sun was conducted. A molecular envelope was detected surrounding 36 of the 66 stars examined. Some of these stars have lower outflow velocities than any Miras previously detected in CO. The average terminal velocity of the ejected material was 7.0 km/sec, about half the value found in Miras selected by infrared criteria. None of the stars with spectral types earlier than M 5.5 were detected. The terminal velocity increases as the temperature of the stellar photosphere decreases, as would be expected for a radiation driven wind. Mass loss rates for the detected objects were calculated, and it was found that there is no correlation between the infrared color of a Mira variable, and its mass loss rate. The mass loss rate is correlated with the far infrared luminosity, although a few stars appear to have extensive dust envelopes without any detectable molecular wind. A power-law relationship is found to hold between the mass loss rate and the terminal velocity of the ejected material. This relationship indicates that the dust envelope should be optically thick in the near infrared and visible regions of the spectrum when the outflow velocity is > 17 km/sec. At the low end of the range of outflow velocities seen, the dust drift velocity may be high enough to lead to the destruction of the grains via sputtering. Half of the stars which were detected were re-observed in the CO(4-3) transition. A comparison of the outflow velocities obtained from these observations with those obtained by other investigators at lower frequencies shows no evidence for gradual acceleration of the outer molecular envelope.

Advanced nonlinear analysis of masonry arch bridges
Creators: name: Zhang, Yanyang
Publisher: name: Imperial College London
Year: 2014

description: This research investigates the nonlinear response up to collapse of masonry arches and arch bridges using advanced numerical descriptions. Past research has shown that the mesoscale modelling approach for brick-masonry, where bricks and mortar joints are modelled separately, may offer a realistic representation of the mechanical behaviour of masonry components. However, because of the significant computational cost, thus far the use of this modelling strategy has been mainly restricted to 2D analysis of masonry arches and arch bridges. In some cases this may lead to a crude representation of the response which is inherently three-dimensional, especially when the analysed structure is subjected to eccentric loading or is characterised by a complex geometry (e.g. skew arches). In this work, masonry arches and arch bridges are analysed using a partitioned mesoscale approach, which enables the use of a detailed model for describing material nonlinearity at structural scale. This is combined with a partitioned approach allowing for parallel computation which guarantees computational efficiency. In the 3D mesoscale description, brick units and mortar interfaces are modelled separately accounting for the actual texture and arrangement of masonry. 3D elastic continuum solid elements are used to model brick units while mortar interfaces are modelled by means of 2D nonlinear interface elements. In analysing masonry bridges, the backfill material is modelled as an elasto-plastic continuum, while the physical interface between the continuum and mesoscale domain for masonry is represented by nonlinear zero-thickness interface elements allowing separation and plastic sliding. The proposed modelling approach has been applied to the analysis of multi-ring square and skew arches and masonry arch bridges. The numerical results, which also include numerical-experimental comparisons, confirm the accuracy of the adopted numerical strategy. Moreover numerical simulations have been performed to investigate the effects of the arch geometry, loading positions, material characteristics and potential settlements at the supports. The results obtained offer important information and a detailed description on the complex response of these critical structural systems under different loading and boundary conditions.

A Reanalysis of the Carbon Abundance in the Translucent Cloud toward HD 24534

description: We have reanalyzed the Goddard High Resolution Spectrograph data set presented by Snow et al. which contains the interstellar intersystem C II] 2325A line through the translucent cloud toward HD 24534 (X Persei). In contrast to the results of Snow et al., we clearly detect the C II] feature at the 3-sigma confidence level and measure a C^+ column density of 2.7 +/- 0.8 x 10^17 cm^-2. Accounting for the C I column density along the line of sight, we find 10^6 C/H = 106 +/- 38 in the interstellar gas toward this star. This gas-phase carbon-to-hydrogen ratio suggests that slightly more carbon depletion may be occurring in translucent as compared to diffuse clouds. The average diffuse-cloud C/H, however, is within the 1-sigma uncertainty of the measurement toward HD 24534. We therefore cannot rule out the possibility that the two cloud types have comparable gas-phase C/H, and therefore comparable depletions of carbon.
