Rapid Evolution of Volatile CO from the Protostellar Disk Stage to the Protoplanetary Disk Stage

description: Recent observations show that the CO gas abundance, relative to H$_2$, in many 1-10 Myr old protoplanetary disks may be heavily depleted, by a factor of 10-100 compared to the canonical interstellar medium value of 10$^{-4}$. When and how this depletion happens can significantly affect compositions of planetesimals and atmospheres of giant planets. It is therefore important to constrain if the depletion occurs already at the earliest protostellar disk stage. Here we present spatially resolved observations of C$^{18}$O, C$^{17}$O, and $^{13}$C$^{18}$O $J$=2-1 lines in three protostellar disks. We show that the C$^{18}$O line emits from both the disk and the inner envelope, while C$^{17}$O and $^{13}$C$^{18}$O lines are consistent with a disk origin. The line ratios indicate that both C$^{18}$O and C$^{17}$O lines are optically thick in the disk region, and only $^{13}$C$^{18}$O line is optically thin. The line profiles of the $^{13}$C$^{18}$O emissions are best reproduced by Keplerian gaseous disks at similar sizes as their mm-continuum emissions, suggesting small radial separations between the gas and mm-sized grains in these disks, in contrast to the large separation commonly seen in protoplanetary disks. Assuming a gas-to-dust ratio of 100, we find that the CO gas abundances in these protostellar disks are consistent with the ISM abundance within a factor of 2, nearly one order of magnitude higher than the average value of 1-10 Myr old disks. These results suggest that there is a fast, $\sim$1 Myr, evolution of the abundance of CO gas from the protostellar disk stage to the protoplanetary disk stage.

description: The implications of the current commercial agricultural debt problem and declining creditworthiness causes doubt about the continued financing of this sector. By positioning both the commercial and developing agricultural sectors in such a manner that it can prove to it's (potential) financiers that it poses acceptable business risks, financiers will probably continue to be involved. Several internal as well as external factors are currently influencing the agricultural sector and is the outcome of these factors of particular significance. This requires strong strategic inputs by all parties concerned.

description: Noise pollution is becoming a crucial problem in France as traffic is rapidly increasing. Therefore, quieter pavements are requested by many communities such as Limoges Metropole. The latter ordered the use of a low noise porous asphalt. This product is used as a wearing course. It is characterized by its phonic properties and improved skid resistance. However, due to its high content of voids (≥ 20%), its mechanical properties might not be as optimal as a conventional asphalt (BBSG: Semi-coarse asphalt concrete). Therefore, this work seeks to determine the durability of the requested porous asphalt experimentally. Tension/compression tests were carried out using samples cored from slabs. The experiments were performed for several temperatures (-10, 0, 10, 15, 20 °C) and frequencies (0.1, 0.3, 1, 3, 10 Hz). The results obtained show that the studied porous asphalt is a decent product compared to other asphalts.

description: The objectives of the workshop were to (a) explain the concept of economic concentration and (b) critically analyse concentration in the Dairy and Red Meat sectors. Restrictive regulations were cited, among other factors, as a cause of concentration in both sectors. Policymakers therefore need to implement deregulation and promote contestable markets to prevent potential abuse (restrictive practices and price collusion).

description: Effective field theory provides a way of parameterizing strong-field deviations from General Relativity that might be observable in the gravitational waves emitted in a black hole merger. To perform numerical simulations of mergers in such theories it is necessary that the equations be written in a form that admits a well-posed initial value formulation. We study gravity coupled to a scalar field including the leading (4-derivative) effective field theory corrections. We introduce a new class of "modified harmonic" gauges and gauge-fixed equations of motion, such that, at weak coupling, the equations are strongly hyperbolic and therefore admit a well-posed initial value formulation.

Demand and Price Analysis

description: A simultaneous-equation model containing yellow maize export demand and supply functions was specified and estimated by Two-Stage Least Squares using annual data for the period 1960-1990. Export demand was influenced by the world price (real) of yellow maize and lagged exports. Export supply was explained by the lagged domestic producer price, lagged exports and random shocks in supply. The price elasticity of export demand estimated directly from the model was high (-37.90), but lower than that estimated by Johnson's indirect method (-181.30). Export supply in the short- and long-run was price inelastic and relatively more responsive to supply shocks. These results support a priori expectations that local yellow maize producers are price takers on the world market and that export supply reacts sluggishly to changes in the lagged producer price of yellow maize. Climatic variation was the major determinant of export supply. Implications for future yellow maize export supply of potential world trade liberalisation and niche marketing are discussed.
Interpreting the parable of the rich man and Lazarus (Luke 16:19-31): An application and evaluation of the SIFT methodology.
Creators: name: Loftus, Francis
Publisher: name: University of Leicester
Year: 2024
Subjects: Uncategorized

description: This empirical study was designed to explore and to evaluate the contribution of the SIFT approach to biblical hermeneutics for interpreting the parable of the rich man and Lazarus (Luke 16:19-31). The SIFT approach is a recent addition to hermeneutical theories, rooted in the reader perspective approach and informed by the development of the Jungian theory of psychological type. The opening four chapters provide the theoretical context for the empirical study by exploring the historical trajectory of biblical hermeneutics, examining how different hermeneutical approaches have added to the interpretation of this parable. The roots and development of the SIFT approach are examined in discussion of reader response within hermeneutical theory, in the nature of ordinary theology and in psychological type theory. Then the fifth chapter roots the study in the discussion of methodology. In the empirical component to this study 16 individuals (one from each of the 16 complete psychological types) were interviewed to elicit their interpretation of the parable of the rich man and Lazarus. The results from their interviews are discussed in eight chapters, with each chapter presenting the interpretation of two contrasting types. These chapters support the conclusion that the interpretation of individual readers reflects their unique psychological type and helps to validate the theory underpinning the SIFT approach to biblical hermeneutics.

Publisher: name: The Open University

description: The experiences and conceptions of learning of five Open University adult students are reported and explored in this study. The students were studying Open Mathematics, a first level 30 point supported distance-learning course. The course included activities designed to encourage active and reflective learning.

A phenomenographic approach was used to capture a variety of students’ conceptions of learning, including their awareness of their own learning (metacognition). I interviewed each student individually three times, twice during the year of the course and again one year later. I asked the students to think about their learning in a reflective way and to report on any changes in their learning.

This study found that the students tended to separate the mathematical activities from the Teaming to learn’ activities, sometimes resisting or even deliberately avoiding the latter. However a variety of issues was raised and explored, such as the different kinds of writing required by this course and the uses and meanings of the language of learning. Other issues included barriers to learning, problems of finding time for study and the difference between distance-learning and face-to-face study.

With such a small number of students, generalisations were not possible or even aimed for. Instead the study shows a wide range of different experiences and preconceptions of learning and describes changes in learning made by the students during the course.

La diffusion Rayleigh permet d’effectuer des mesures réparties permettant d’obtenir plus de données que les méthodes classiques de mesure de déformation basées la plupart du temps sur des mesures ponctuelles. Les mesures de déformations circonférentielles des alvéoles sont exploitées par analyse inverse, grâce à un modèle éléments finis, pour calculer la variation de section. Les performances de la méthode proposée sont ensuite évaluées grâce à des essais menés sur un démonstrateur réalisé à l’échelle une.

description: Four phases of formal strategic decision-making were identified. The distinguishing characteristics of the four phases were extrapolated to grain cooperatives in the Republic of South Africa. It was determined that they are in the first two phases of formal strategic decision-making and that as a group they are therefore not strategically managed. A greater degree of strategic management of grain cooperatives will ensure increasingly effective strategic decision-making which should have a positive impact on inter alia capital formation.

Excess C/H in Protoplanetary Disk Gas from Icy Pebble Drift across the CO Snowline

description: The atmospheric composition of giant planets carries the information of their formation history. Superstellar C/H ratios are seen in atmospheres of Jupiter, Saturn, and various giant exoplanets. Also, giant exoplanets show a wide range of C/O ratio. To explain these ratios, one hypothesis is that protoplanets accrete carbon-enriched gas when a large number of icy pebbles drift across the CO snowline. Here we report the first direct evidence of an elevated C/H ratio in disk gas. We use two thermo-chemical codes to model the $^{13}$C$^{18}$O, C$^{17}$O, and C$^{18}$O (2-1) line spectra of the HD 163296 disk. We show that the gas inside the CO snowline ($\sim$70 au) has a C/H ratio of 1-2 times higher than the stellar value. This ratio exceeds the expected value substantially, as only 25-60% of the carbon should be in gas at these radii. Although we cannot rule out the case of a normal C/H ratio inside 70 au, the most probable solution is an elevated C/H ratio of 2-8 times higher than the expectation. Our model also shows that the gas outside 70 au has a C/H ratio of 0.1$\times$ the stellar value. This picture of enriched C/H gas at the inner region and depleted gas at the outer region is consistent with numerical simulations of icy pebble growth and drift in protoplanetary disks. Our results demonstrate that the large-scale drift of icy pebble can occur in disks and may significantly change the disk gas composition for planet formation.

description: We describe the simultaneous effects of the spin-orbit (SO) perturbation and a magnetic field $B$ on a disk shaped quantum dot (QD). {As it is known the} combination of electrostatic forces among the $N$ electrons confined in the QD and the Pauli principle can induce a spin polarization when $B$ (applied in the direction orthogonal to the QD) is above a threshold value. In the presence of an electric field parallel to $B$, coupled to the spin $ S $ by a Rashba term, we demonstrate that a symmetry breaking takes place: we can observe it by analyzing the splitting of the levels belonging to an unperturbed multiplet. We also discuss the competitive effects of the magnetic field, the SO perturbation and the electron electron interaction, in order to define the hierarchy of the states belonging to a multiplet. We demonstrate how this hierarchy depends on the QD's size. We show the spin texture due to the combined effects of the Rashba effect and the interaction responsible for the polarization.

description: With the increased awareness of environmental issues, research on earth concrete as an alternative construction material has gained a renewed interest. Compared to conventional concrete, this material is less resistant and hence better knowledge of the mechanical behavior is required. In the present paper, the mechanical response of earth concrete is assessed. Finite elements simulations are performed at the macroscopic scale using Fichant's isotropic damage model in order to have a better understanding of the fracture behavior of these materials and to determine their mechanical properties. The capability of the model is valued by comparing the results of the numerical simulations with the corresponding experimental ones. The results reveal the ability of this damage model to successfully describe the mechanical behavior and performance of earth concrete materials.

description: A negative basis trade enters a long bond position and buys protection on the issuer of the bond through credit default swap (CDS), aiming at arbitrage profit due to the bond-CDS basis. To classic reduced form model theorists, the existence of the basis is an abnormality or merely liquidity noise. Such a view, however, fails to explain large basis trading losses incurred during the financial crisis. Employing a bond continuously hedged by CDS under a dynamic spread model with bond repo financing, we find that there is unhedged and unhedgeable residual jump to default risk that can't be diversified because of credit correlation. An economic capital approach has to apply and a charge on the use of capital follows. Together with the hedge funding cost, it allows us to better understand the basis's economics and to predict its fair level.

description: The analysis of the experimental data of Crystal Barrel Collaboration on the p anti-p annihilation in flight with the production of mesons in the final state resulted in a discovery of a large number of mesons over the region 1900-2400 MeV, thus allowing us to systematize quark-antiquark states in the (n,M^2) and (J,M^2) planes, where n and J are radial quantum number and spin of the meson with the mass M. The data point to meson trajectories in these planes being approximately linear, with a universal slope. Basing on these data and results of the recent K-matrix analysis a nonet classification is performed. In the scalar-isoscalar sector, the broad resonance state f0(1200-1600) is superfluous for the q anti-q classification, i.e. it is an exotic state. The ratios of coupling constants for the transitions f0-> pi pi, K anti-K, eta eta, eta eta' point to the gluonium nature of the broad state f0(1200-1600). The problem of the location of the lightest pseudoscalar glueball is also discussed.

description: De nos jours, l’utilisation des matériaux de construction écologiques et durables comme le béton de terre est devenue nécessaire. Ces matériaux sont composés essentiellement de particules fines comme l'argile qui les rendent très sensible au retrait ce qui peut avoir un effet néfaste sur leur durabilité. Dans cette étude, le retrait à long terme (à partir de 24h) et l’effet des conditions de cure sur la résistance mécanique du béton de terre ont été étudiés. Une investigation expérimentale sur l’évolution de l’endommagement pendant le retrait de dessiccation a été réalisée à l’aide de la technique d’émission acoustique (EA). Cette technique permet un suivi continu de l’endommagement en fonction du temps. La résistance du béton de terre diminue pour les éprouvettes conservées à de faible humidité relative. De plus, les résultats d’EA associés au retrait et à la mesure de perte de masse ont permis de décrire qualitativement le processus de séchage avec une activité acoustique fortement corrélée au taux de retrait.

description: We make two remarks about the null-controllability of the heat equation with Dirichlet condition in unbounded domains. Firstly, we give a geometric necessary condition (for interior null-controllability in the Euclidean setting)which implies that one can not go infinitely far away from the control region without tending to the boundary (if any), but also applies when the distance to the control region is bounded. The proof builds on heat kernel estimates. Secondly, we describe a class of null-controllable heat equations on unbounded product domains. Elementary examples include an infinite strip in the plane controlled from one boundary and an infinite rod controlled from an internal infinite rod. The proof combines earlier results on compact manifolds with a new lemma saying that the null-controllability of an abstract control system and its null-controllability cost are not changed by taking its tensor product with a system generated by a non-positive self-adjoint operator.

description: (Abridged) We have surveyed four globular clusters in the Fornax dwarf galaxy for RR Lyrae stars, using archival HST observations. We identify 197 new RR Lyrae stars in these four clusters. Despite the short observational baseline, we derive periods, light-curves, and photometric parameters for each. The Fornax clusters have exceptionally large RR Lyrae specific frequencies compared with the Galactic globular clusters. Furthermore, the Fornax cluster RR Lyrae stars are unusual in that their characteristics are intermediate between the two Galactic Oosterhoff groups. In this respect the Fornax clusters are similar to the field populations in several dwarf galaxies. We revise previous measurements of the HB morphology in each cluster. The Fornax clusters closely resemble the ``young'' Galactic halo population defined by Zinn. The existence of the second parameter effect among the Fornax clusters is also confirmed. Finally, we determine foreground reddening and distance estimates for each cluster. We find a mean distance modulus to Fornax of (m-M)_0 = 20.66 +/- 0.03 (random) +/- 0.15 (systematic). Our measurements are consistent with a line of sight depth of 8-10 kpc for this galaxy, matching its projected dimensions, and incompatible with tidal model explanations for the observed high velocity dispersions in many dSph galaxies. Dark matter dominance is suggested.

description: Controlling the pathways and outcomes of reactions is a broadly pursued goal in chemistry. In gas phase reactions, this is typically achieved by manipulating the properties of the reactants, including their translational energy, orientation, and internal quantum state. In contrast, here we influence the pathway of a reaction via its intermediate complex, which is generally too short-lived to be affected by external processes. In particular, the ultracold preparation of potassium-rubidium (KRb) reactants leads to a long-lived intermediate complex (K$_2$Rb$_2^*$), which allows us to steer the reaction away from its nominal ground-state pathway onto a newly identified excited-state pathway using a laser source at 1064 nm, a wavelength commonly used to confine ultracold molecules. Furthermore, by monitoring the change in the complex population after the sudden removal of the excitation light, we directly measure the lifetime of the complex to be $360 \pm 30$ ns, in agreement with our calculations based on the Rice-Ramsperger-Kassel-Marcus (RRKM) statistical theory. Our results shed light on the origin of the two-body loss widely observed in ultracold molecule experiments. Additionally, the long complex lifetime, coupled with the observed photo-excitation pathway, opens up the possibility to spectroscopically probe the structure of the complex with high resolution, thus elucidating the reaction dynamics.

description: Cette étude est relative à la détermination des cinétiques de précipitation/dissolution des principaux minéraux constitutifs du Géocorail, un éco-matériau formé à partir d’un dépôt calco-magnésien et destiné au renforcement des ouvrages côtiers et à la lutte contre le recul du trait de côte. Pour ce faire, la dissolution d’une poudre de Géocorail, constituée d’un mélange de brucite, d’aragonite et d’une faible quantité de calcite, dans une solution d’eau de mer naturelle pendant 5 jours a été modélisée à partir du code PHREEQC Version 3. Les résultats obtenus ont été ensuite ajustés à partir des données expérimentales issus d’une étude antérieure afin d’obtenir un modèle cinétique fidèle au procédé en conditions réelles. L’analyse comparative des résultats découlant de cette démarche met en évidence une différence notable avec les paramètres cinétiques issus de la littérature. Une bonne concordance est cependant obtenue avec les données expérimentales et permet de déduire les constantes cinétiques de chaque minéral ainsi que le rapport de concentration Mg/Ca au-delà duquel l’aragonite précipite au détriment de la calcite. Ces cinétiques doivent néanmoins être validées sur des temps plus courts.

description: We measure the rates of type I X-ray bursts, as a function of the bolometric luminosity, from a likely complete sample of 37 non-pulsing transients (1996-2004). Our goals are to test the burst model for neutron stars and to investigate whether black holes have event horizons. We find 135 type I bursts in 3.7 Ms of exposure for the neutron-star group, and the burst rate function is generally consistent with model predictions. However, for the black hole groups (18 sources), there are no confirmed type I bursts in 6.5 Ms of exposure, and the upper limits in the burst function are inconsistent with the model predictions for heavy compact objects with a solid surface. There are systematic spectral differences between the neutron-star and black-hole groups, supporting the presumption that physical differences underly the sample classifications. These results provide indirect evidence that black holes do have event horizons.

description: The International Institute of Tropical Agriculture and collaborating partners have been introducing and disseminating short season soybean varieties among farm households in the Sudan savannas of Northern Nigeria since 2008. This study estimated the impact of soybean production on nutrition of 0-5 year children and dietary diversities of the households in Kano State, Nigeria of the early maturing soybean. A total of 1133 children (488 girls and 645 boys) across the three LGAs of Bunkure, Shanono and Dawakin Tofa, aged between 0-60 months were surveyed using the variables (WFA) Weight for Age, (HFA) (Height for Age) and WFH (Weight for Height). The anthropometric indices were used to obtain the Z scores of sampled children (age 1-5 years). Results of the anthropometric indices from the study generally showed a low prevalence of malnutrition among the children sampled for all the nutritional variables. Majority of the children fall within the normal Z score values (Z > -1). Across the LGAs, malnutrition is noticed only among children of the non-soybean producing households in Shanono LGA. Findings from the study showed that the frequency of the intake of soybean related meals compares favorably with the intake of cereals and other legumes related meals across the 3 LGAs on daily, weekly and monthly basis.

description: We report a lithographic process for creating high-resolution (<10 nm) carbon templates on Si(100). A scanning electron microscope, operating under low vacuum (10E-6 mbar), produces a carbon-containing deposit ("contamination resist") on the silicon surface via electron-stimulated dissociation of ambient hydrocarbons, water and other adsorbed molecules. Subsequent annealing at temperatures up to 1320 K in ultra-high vacuum removes SiO2 and other contaminants, with no observable change in dot shape. The annealed structures are compatible with subsequent growth of semiconductors and complex oxides. Carbon dots with diameter as low as 3.5 nm are obtained with a 200 us electron-beam exposure time.

title: Functional characterisation of the human S1P₄G protein-coupled receptor
Creators: name: Holdsworth, Gillian
Publisher: name: The Open University
Year: 2003

description: The human G protein-coupled receptor (GPCR) S1P4 (formerly named Edg6) was identified as an orphan receptor and assigned to the Edg family on the basis of sequence similarity with other Edg receptors. S1P4 was recently shown to couple to Gαi and Gα12/13 G proteins in response to stimulation by the lysophospholipid, sphingosine-1-phosphate (S1P). This thesis describes functional characterisation of the S1P4 receptor using a modified [35S]GTPγS binding assay. CHO-K1 cells were stably transfected to express S1P4, or a fusion protein between S1P4 and a pertussis toxin-resistant form of Gαi1. S1P4 exhibited significant constitutive activity and treatment with SIP or phytoSIP further stimulated the receptor in a dose-dependent manner. Pertussis toxin treatment demonstrated that both S1P4 constitutive activity and the effects of SIP were transduced via endogenous Gαi G proteins, whilst the SlP4-Gαi1 fusion signalled via the tethered, pertussis toxin-insensitive G protein. Residue was shown to be important in governing S1P4 ligand selectivity; mutation of the naturally occurring glutamic acid to glutamine attenuated the ability of the receptor to respond to S1P and conferred sensitivity to the related compound, lysophosphatidic acid. Since most cell types express endogenous S1P and LPA family receptors, the profile of Edg family receptor expression in CHO-K1 cells was investigated. Transcripts for S1P1,2,4 and LPA1 receptors were detected using RT-PCR with species-specific oligonucleotides. Further investigations into S1P4 constitutive activity, which were undertaken using an inducible expression system, demonstrated direct correlation between S1P4 expression and constitutive activity. This suggested that S1P4 constitutive activity represents an inherent property of this receptor. In common with other naturally constitutively active GPCRs, S1P4 lacks a generally conserved cysteine residue within the first extracellular loop. It is proposed that this may account for S1P4 constitutive activity and may be relevant to the in vivo function of this receptor.

description: Cette étude expérimentale a pour but d’évaluer l’influence de l'incorporation du sable recyclé sur les variations dimensionnelles des mortiers de maçonnerie dues au retrait, et aux effets des cycles séchage-imbibition. Ces propriétés physiques ont été déterminées sur différentes compositions de mortiers de ciment avec et sans adjuvants, confectionnées à base du ciment CEM I 52,5 et un rapport sable/ciment (S/C) =3,0, en substituant le sable naturel par le sable recyclé avec différents pourcentages volumiques de : 0, 15, 30, 40, 50, 75 et 100 %. Pour chaque mortier, 18 éprouvettes, de forme prismatique (4x4x16 cm³), ont été confectionnées afin d’évaluer le retrait endogène ainsi que le retrait libre dans trois milieux différents : en salle sèche, à l’air ambiant (salle du laboratoire) et salle humide. En conséquence, la variation de masses et la résistance en compression ont été évaluées sur six éprouvettes qui ont subi 12 cycles séchage-imbibition. Les résultats montrent en général que les retraits sont plus importants dans la salle sèche et qui sont en relation directe avec l’augmentation du taux de substitution du sable naturel par celui recyclé, et moins prononcés avec l’incorporation du superplastifiant. Cependant, sous l’effet de l’humidité (en salle humide) et des cycles séchage-imbibition, les éprouvettes ont subi des gonflements, particulièrement pour le mortier recyclé à 100%.

description: Les matériaux écologiques de construction tels que le béton de terre contenant une proportion de divers composants écologiques sont de grande importance aujourd'hui. L'objectif de la production de ce béton est de réduire la consommation de ciment et donc la réduction de l’émission de CO2. Le présent travail étudie l'effet de sable de dune sur la durabilité des bétons de terre compressée et stabilisée (BTCS) après 12 cycles de séchage/mouillage, de point de vue : perte de masse, résistance à la compression et absorption totale en eau. Dans ce cadre, on a utilisé cinq teneurs en sable (0, 20, 40, 60 et 80 %) du poids du mélange sec, avec 10% de ciment pour le stabiliser. Le mélange est compacté avec deux contraintes différentes (10 et 20MPa). Les échantillons (moules Proctor) ont été conservés au laboratoire à une température T= 20°C pendant 28 jours. Les résultats indiquent que la résistance à la compression et la durabilité des (BTC) sont bien meilleures pour un taux de sable de 20% et une contrainte de compactage de 20MPa.

A simple SIR model with a large set of asymptomatic infectives

Year: 2020
Subjects: subject: Populations and Evolution (q-bio.PE)
subject: FOS: Biological sciences

description: There is increasing evidence that one of the most difficult problems in trying to control the ongoing COVID-19 epidemic is the presence of a large cohort of asymptomatic infectives. We develop a SIR-type model taking into account the presence of asymptomatic, or however undetected, infective, and the substantially long time these spend being infective and not isolated. We discuss how a SIR-based prediction of the epidemic course based on early data but not taking into account the presence of a large set of asymptomatic infectives would give wrong estimate of very relevant quantities such as the need of hospital beds, the time to the epidemic peak, and the number of people which are left untouched by the first wave and thus in danger in case of a second epidemic wave. In the second part of the note, we apply our model to the COVID-19 epidemics in Italy. We obtain a good agreement with epidemiological data; according to the best fit of epidemiological data in terms of this model, only 10\% of infectives in Italy is symptomatic.
