description: The strategic prospects for the US (or any) economy can be evaluated by reference to the financial balances of its main sectors, which are related to one another by a consistent accounting system. The 1992-2000 expansion, accompanied by a rising budget surplus, was greeted by a storm of self-congratulation in the US and widely expected to last indefinitely. But inspection of the balances revealed that the configuration of driving forces was unsustainable and that the fiscal stance should drastically change at some stage. Eventually, there has indeed been a huge fiscal expansion which warded off an incipient recession. But the new configuration of financial balances again reveals an unsustainable situation, with government, foreign and private debt all rising excessively fast. Sustained growth in the medium term can only be achieved if there is now a prolonged expansion in net export demand--for which the rest of the world does not seem to be well prepared.

description: Two studies were conducted to determine the effect of physical barriers (black plastic, weed barrier and grass mulch) and a bare soil treatment on sweet potato weevil (SPW) infestation of "Viola" and "Sunny" sweet potato cultivars. Harvested roots were individually inspected and rated on a SPW damage index (DI) of 1-6 ( I - no damage, 6 - most severe damage). A mean damage index (MDI) was also calculated. All medium-sized storage roots with a DI rating _ 2 were considered as marketable yield. The yield of medium-sized roots for the "Sunny" cultivar was significantly higher under plastic mulch than on bare soil. The grass mulch treatment produced a higher percentage of storage roots rated DI-1 than plots with synthetic mulches (plastic or weed barrier). The grass mulch treatment also produced a higher percentage of medium-sized marketable roots than the weed barrier treatment. Sweet potatoes from the weed barrier plots had a higher MDI than those in the grass mulch plots. In the "Viola" study, the grass mulch treatment produced the highest total and marketable yields. The weed barrier treatment had a higher MDI, a lower percentage of roots rated DI-1 and a higher percentage of roots rated DI-6 than all the other treatments. These trials have demonstrated that grass mulch has more potential than weed barrier for controlling SPW.

description: The rise-up in boron neutrino spectrum at low energies has been studied within the framework of `pure LMA' scenario. Indirect bounds on the spectral `upturn' have been obtained from the available solar neutrino data. These bounds have been used to demonstrate the efficacy of the precision measurements of the `upturn' for further constraining the neutrino parameter space allowed by SNO salt phase data. The sterile neutrino flux has been constrained in the light of the recent 766.3 Ty KamLAND spectral data.

description: Récemment introduit à la Martinique, la présence de Scutellonema bradys dans les champs d'igname cultivés en rotation avec d'autres cultures, ne s'explique, pour l'instant, que par l'utilisation de matériel végétal infesté. Dans le semenceau, la population de S. bradys est composée de femelles, de mâles et de juvéniles en proportions équivalentes. Après la mise en terre, seules les femelles sont capables de se déplacer vers les racines et vers le néo-tubercule. Le transit ne s'effectue pas par le chemin racinaire via le prétubercule, mais par le sol. Le processus de germination et de tubérisation favorise cette migration. Comme les femelles sont fécondées avant de quitter les tissus parenchymateux du plant, elles pondent dès leur pénétration dans les tissus végétaux. Pour préserver les racines des attaques de S. bradys, il suffit d'enrober le semenceau dans un matériau qui laisse passer le germe, mais pas les nématodes, comme par exemple la cire. ----- Definition of a control method for the yam nematode Scutellonema bradys with the help of the population dynamic studies. Recently introduce in Martinique, the occurence of Scutellonema bradys in yam fields rotated with other crops only results nowaday from the used of infested planting material. In the seed tuber, the S. bradys population is composed of equal proportions of females, males and juveniles. After planting, only females are able to move to roots and neo-tuber. The nematodes do not invade the root via the bud, but transit in the soi!. Germination and tuber emergence favorise the migration. As females are fertilized before to leave the seed tissue, they lay eggs immediatly after penetration. To prevent roots from nematode attacks, it is enough to coat the seed tuber with a material wich allow the passage of the shoot but not of the nematodes, such as wax

description: Hard X-ray spectra in solar flares provide knowledge of the electron spectrum that results from acceleration and propagation in the solar atmosphere. However, the inference of the electron spectra from solar X-ray spectra is an ill-posed inverse problem. Here we develop and apply an enhanced regularization algorithm for this process making use of physical constraints on the form of the electron spectrum. The algorithm incorporates various features not heretofore employed in the solar flare context: Generalized Singular Value Decomposition (GSVD) to deal with different orders of constraints; rectangular form of the cross-section matrix to extend the solution energy range; regularization with various forms of the smoothing operator; and "preconditioning" of the problem. We show by simulations that this technique yields electron spectra with considerably more information and higher quality than previous algorithms.

description: L'igname est l'une des principales plantes à tubercule cultivé en zone tropicale. Actuellement, avec la nécessité d'augmenter la production à des coûts favorables, la tendance est au développement croissant de cette culture qui occupe de plus en plus de zones mécanisables. L'une des conditions essentielles pour réussir une culture d'igname consiste à réaliser une bonne préparation du sol pour faciliter l'amélioration de l'enracinement et la tubérisation. C'est ce point fondamental qui a fait l'objet de notre étude. Nous avons en effet ; comparé plusieurs modes de préparation de sol et testé leur incidence sur l'enracinement et le développement des tubercules de l'igname. Les résultats de cette étude nous ont permis de mettre au point un billonneur pour une préparation du sol adaptée à la culture de l'igname.

description: The phenomenon of diquark condensation at non-zero baryon density and zero temperature is analyzed in the strong coupling limit of lattice QCD. The results indicate that there is attraction in the quark-quark channel also at strong coupling, and that the attraction is more effective at high baryon density, but for infinite coupling it is not enough to produce diquark condensation. It is argued that the absence of diquark condensation is not a peculiarity of the strong coupling limit, but persists at sufficiently large finite couplings.

description: Light-exposure of sprouting tubers of both sweet potato and yam bean caused "greening" in the periderm; however, the light-induced inhibition of tuber growth observed in sweet potato was not observed in yam bean tubers. Examination of the protein profiles and isoperoxidase banding patterns revealed no significant differences between lightexposed and dark-grown tuber tissue. While the basis of this lightmediated effect on starch accumulation may not be easily determined within the limits of biochemical assays, it has now become possible, with the emerging new molecular techniques, to determine whether this phenomc.non is due to the differential expression of the genes coding for the enzymes responsible for starch biosynthesis viz A(U)DP glucose pyrophosphorylase and starch synthase. The paper highlights the further advantages of using molecular approaches to the understanding of the tuberisation process.

description: This paper investigates the application of a unified non-orthogonal multiple access framework in beam hopping (U-NOMA-BH) based satellite communication systems. More specifically, the proposed U-NOMA-BH framework can be applied to code-domain NOMA based BH (CD-NOMA-BH) and power-domain NOMA based BH (PD-NOMA-BH) systems. To satisfy dynamic-uneven traffic demands, we formulate the optimization problem to minimize the square of discrete difference by jointly optimizing power allocation, carrier assignment and beam scheduling. The non-convexity of the objective function and the constraint condition is solved through Dinkelbach's transform and variable relaxation. As a further development, the closed-from and asymptotic expressions of outage probability are derived for CD/PD-NOMA-BH systems. Based on approximated results, the diversity orders of a pair of users are obtained in detail. In addition, the system throughput of U-NOMA-BH is discussed in delay-limited transmission mode. Numerical results verify that: i) The gap between traffic requests of CD/PD-NOMA-BH systems appears to be more closely compared with orthogonal multiple access based BH (OMA-BH); ii) The CD-NOMA-BH system is capable of providing the enhanced traffic request and capacity provision; and iii) The outage behaviors of CD/PD-NOMA-BH are better than that of OMA-BH.

description: A test of the benchmark QED process e+e- -> gamma gamma (gamma) is reported, using the data collected with the DELPHI detector at LEP 2. The data analysed were recorded at centre-of-mass energies ranging from 161 GeV to 208 GeV and correspond to a total integrated luminosity of 656.4 pb^{-1}. The Born cross-section for the process e+e- -> gamma gamma (gamma) was determined, confirming the validity of QED at the highest energies ever attained in electron-positron collisions. Lower limits on the parameters of a number of possible deviations from QED, predicted within theoretical frameworks expressing physics beyond the Standard Model, were derived.

description: Der ländliche Raum unterliegt einem Nutzungswandel. Wirtschaftliche, kulturelle und demographische Entwicklungen haben den Alpenraum im letzten Jahrhundert transformiert. Zahlreiche Ortskerne in ruralen Gebieten sind durch Abwanderung und Verlagerung diverser Funktionen durch Leerstand geprägt. Die folgende Arbeit behandelt dieses Phänomen der räumlichen Entwicklungen anhand von Bad Gastein. Bad Gastein, ein traditioneller Sommerkurort und nun Wintersportparadies, zählt zu den ältesten Tourismusregionen Österreichs. Es ist ein Ort der Extreme - hohe Berge kesseln den Ort ein, der sich über mehrere Ebenen erstreckt, und ein mächtiger Wasserfall durchschneidet das Zentrum. Man trifft auf Architekturen aus unterschiedlichen Epochen, doch im historischen Ortskern findet man seit Jahren leerstehende Gebäude. Währenddessen entsteht ein neues Zentrum nahe dem Bahnhof. Bad Gastein bildet einen spannenden und heterogenen Raum, jedoch ohne Perspektiven. In dieser Arbeit wird der Ort analysiert um Qualitäten, Defizite und Potentiale herauszufiltern. Mit unterschiedlichen Maßnahmen, Maßstäben und einer theoretischen Fundierung sollen Strukturen geschaffen werden, die positive Entwicklungen stimulieren und den Ort aus dem Dornröschenschlaf wecken.
description: Rural regions are underlying changes in their utilization. Economic, cultural and demographic developments have transformed the Alpine region in the last century. Especially town centres are being affected by vacancy due to migration, market and interest shifts. This thesis deals with these spatial developments with a focus on the place Bad Gastein. Bad Gastein, a traditional summer health resort and nowadays also a well-known winter sport paradise, is one of the oldest tourism regions of Austria. It is a place of extremes - tall mountains surround the city, which extends over several height levels, and a dominant waterfall intersects its structure. Architecture out of different epochs characterises the historical centre, however the majority of the buildings there are vacant. Meanwhile a new centre emerges close by the train station. It's a fascinating and heterogenic place, though without perspectives. The aim of this thesis is to analyse and select the citys qualities, deficits and potentials. Various methods and actions in different scales and theoretical foundation are used to produce new structures to stimulate positive developments in the city with the ambition to resurrect Bad Gastein.

description: We present Chandra and XMM-Newton observations of a small sample (11 objects) of optically-selected Seyfert~2 galaxies, for which ASCA and BeppoSAX had suggested Compton-thick obscuration of the Active Nucleus (AGN). The main goal of this study is to estimate the rate of transitions between "transmission-" and "reprocessing-dominated" states. We discover one new transition in NGC4939, with a possible additional candidate in NGC5643. This indicates a typical occurrence rate of at least ~0.02/year. These transitions could be due to large changes of the obscuring gas column density, or to a transient dimming of the AGN activity, the latter scenario being supported by detailed analysis of the best studied events. Independently of the ultimate mechanism, comparison of the observed spectral dynamics with Monte-Carlo simulations demonstrates that the obscuring gas is largely inhomogeneous, with multiple absorbing components possibly spread through the whole range of distances from the nucleus between a fraction of parsecs up to several hundreds parsecs. As a by-product of this study, we report the first measurement ever of the column density covering the AGN in NGC3393 (N_H ~ 4.4x10^{24} atoms/cm/cm), and the discovery of soft X-ray extended emission, apparently aligned along the host galaxy main axis in NGC5005. The latter object hosts most likely an historically misclassified low-luminosity Compton-thin AGN.

description: Choosing a simple class of flows, with characteristics that may be present in the Earth's core, we study the ability to generate a magnetic field when the flow is permitted to oscillate periodically in time. The flow characteristics are parameterised by D, representing a differential rotation, M, a meridional circulation, and C, a component characterising convective rolls. Dynamo action is sensitive to these flow parameters and fails spectacularly for much of the parameter space where magnetic flux is concentrated into small regions. Oscillations of the flow are introduced by varying the flow parameters in time, defining a closed orbit in the space (D,M). Time-dependence appears to smooth out flux concentrations, often enhancing dynamo action. Dynamo action can be impaired, however, when flux concentrations of opposite signs occur close together as smoothing destroys the flux by cancellation. It is possible to produce geomagnetic-type reversals by making the orbit stray into a region where the steady flows generate oscillatory fields. In this case, however, dynamo action was not found to be enhanced by the time-dependence. A novel approach is taken to solving the time-dependent eigenvalue problem, where by combining Floquet theory with a matrix-free Krylov-subspace method we avoid large memory requirements for storing the matrix required by the standard approach.

description: We describe a way to continue the fermionic renormalization group flow into phases with broken global symmetry. The method does not require a Hubbard-Stratonovich decoupling of the interaction. Instead an infinitesimally small symmetry-breaking component is inserted in the initial action, as an initial condition for the flow of the selfenergy. Its flow is driven by the interaction and at low scales it saturates at a nonzero value if there is a tendency for spontaneous symmetry breaking in the corresponding channel. For the reduced BCS model we show how a small initial gap amplitude flows to the value given by the exact solution of the model. We also discuss the emergence of the Goldstone boson in this approach.

description: A new bookkeeping system called Jiskefet is being developed for A Large Ion Collider Experiment (ALICE) during Long Shutdown 2, to be in production until the end of LHC Run 4 (2029). Jiskefet unifies two functionalities: a) gathering, storing and presenting metadata associated with the operations of the ALICE experiment and b) tracking the asynchronous processing of the physics data. It will replace the existing ALICE Electronic Logbook and AliMonitor, allowing for a technology refresh and the inclusion of new features based on the experience collected during Run 1 and Run 2. The front end leverages web technologies much in use nowadays such as TypeScript and NodeJS and is adaptive to various clients such as tablets, mobile devices and other screens. The back end includes an OpenAPI specification based REST API and a relational database. This paper will describe the organization of the work done by various student teams who work on Jiskefet in sequential and parallel semesters and how continuity is guaranteed by using guidelines on coding, documentation and development. It will also describe the current status of the development, the initial experience in detector stand-alone commissioning setups and the future plans.

description: We review some recent developments in Higgs physics at a $γγ$ collider. We begin with single Higgs boson production in $γγ$ collisions proceeding via the hadronic content of the photon. For SM Higgs masses of current theoretical interest, the resolved photon contributions are non-negligible in precision cross section measurements. We found that production of the heavier Higgs bosons, $H^0$ and $A^0$, of the MSSM can probe regions of the SUSY parameter space that will complement other measurements. We showed that associated $t H^\pm$ production in $γγ$ collisions can be used to make an accurate determination of $\tanβ$ for low and high $\tanβ$ by precision measurements of the $γγ\to H^\pm t +X $ cross section. We then reviewed recent progress on Higgs physics in direct photon processes in which the Higgs bosons are produced via virtual loops. Precision measurements of the magnitude and phase of the $Hγγ$ coupling at a photon collider can be used to determine Higgs parameters related to physics beyond the SM.

description: A la Martinique, l'intensification fourragère par Brachiaria humidicola (Bh) n'a connu qu'un succès modeste, malgré les qualités de cette espèce et son. aptitude à lutter efficacement contre les adventices des milieux humides. A ses possibilités de semis mécanisé s'oppose une installation lente et peu spectaculaire. Pour améliorer ses conditions d'installation de Bh, l'effet de la dose de semences, d'une fumure phosphatée et de l'association au semis de Bh et de Brachiaria decumbens (Bd) ont été étudiés. Ces deux espèces sont en effet complémentaires : Bd se développe en peu de temps, puis est sali plus ou moins rapidement selon la nature du milieu et la qualité de la gestion. En revanche, Bh s'installe très lentement, mais la croissance vigoureuse de ses stolons produit alors un tapis végétal dense qui étouffe toute autre espèce. Les résultats de semis confirment le faible pouvoir germinatif de Bh, qui ne s'installe rapidement que par bouturage. Ni une fumure phosphatée, ni une dose double de semences n'ont d'effet sur son installation. La concurrence entre Bd et Bh s'exerce au départ en faveur de Bd, dont la rapide croissance n'est pas affectée par la présence de Bh. Par la suite, Bh progresse pour devenir la principale "adventice" de Bd. Le salissement des parcelles à Bh reste cependant faible, essentiellement pendant la phase d'installation. L'association produit une prairie mixte qui peut être exploitée rapidement dès 5 mois. La cor. _iétition s'exerce toujours en faveur de Bh et les mauvaises herbes asservies aux deux espèces restent discrètes. Le semis de Bh sous couvert de Bd est un moyen de réduire la durée d'immobilisation des parcelles. En attendant de nouvelles variétés de Bh, à pouvoir germinatif plus élevé, le bouturage reste le mode d'implantation le plus efficace mais aussi le plus coûteux.

description: Trade liberalisation in Mexico started in a significant way in 1985/86, and was consolidated by the NAFTA agreement 1994. Mexico was expected to benefit in terms of increased export growth, employment, real wages, and above all, a faster rate of economic growth. In practice, there has been a divorce between rhetoric and reality. The growth of GDP post-liberalisation has been only one-half that pre-liberalisation. This paper gives three explanations. Firstly, export growth has hardly changed. Secondly, there has been a sharp increase in the propensity to import (partly related to US direct foreign investment) which has reduced the growth of GDP consistent with a sustainable balance of payments equilibrium on current account. Thirdly, liberalisation has been used as a substitute for a development strategy. JEL Codes: F13, F14, F32, O19, O24

The response of the overnight call rate to exchange rates or stock prices lasts longer than the reaction to the output gap and the inflation gap. Except for the lagged overnight call rate, the inflation gap and the exchange rate are more influential than the output gap and stock prices in explaining the variance of the overnight call rate.

description: Relative Sunspot Number is one of the major parameters for the study of long-term solar activity. The automatic calculation of the Relative Sunspot Number is more stable and accurate as compared to manual methods. In this paper, we propose an algorithm that can detect sunspots and divide them into groups, to automatically calculate the Relative Sunspot Number. Mathematical Morphology was adopted to detect sunspots then group them. The dataset used were the continuum images from SDO/HMI. The process was carried out on the overall HMI data available on the timespan from January 2022 to May 2023 with a time cadence of one day. The experimental results indicated that the method achieved high accuracy of 85.3\%. It was well fitted with the international Relative Sunspot Number provided by Solar Influences Data Analysis Center (SIDC) (CC=0.91). We calculated the conversion factor K value of SDO/HMI for calculating the Relative Sunspots Number(K=1.03).

description: A la Martinique, l'usage des réserves sur pied permet le report d'excédents fourragers de la fin de la saison des pluies au Carême. L'aptitude de quatre graminées fourragères à accumuler d'importantes quantités de matière sèche (Tripsacum laxum (Tl), Pennisetum purpureum (Pp), Brachiaria decumbens (Bd) et Panicum maximum (Pm)) est étudiée depuis trois années sur trois sites. Deux dates de mise en défends ont été retenues (un et deux mois avant le début supposé de la période séche). Pendant le Carême, le rendement en matière sèche et l'évolution de la composition morphologique (proportion de feuilles, tiges et débris) ont été mesurés toutes les quinzaines. La moyenne des rendements accumulés pour Bd, Pm, Tl et Pp ont été respectivement de 10.0, 11.3, 15.0 et 21.7 t MS/ha dont 17.5 %, 20.7 %, 40.1 % et 17.1 % de feuilles. T. laxum semble donc recommandé pour cette technique car il accumule jusqu'à 6.0 t MS/ha de feuilles durant la saison sèche, alors que Pp, Pm et Bd n'atteignent que 3.4, 2.3 et 1.7 t MS/ha chacun.

description: Raman microspectroscopy was used to characterize amorphous silica plastic behavior. Using a correlation between Raman spectrum and density, a map of the local residual indentation-induced densification is obtained. The existence of a densification-induced hardening is also evidenced through a diamond anvil cell experiment. Such observations are not accounted for by the previously proposed hardening-free pressure-dependent yield criterion based on indentation curves. These results open the way to more accurate description of a constitutive law for amorphous silica.

description: Kontar et al. (2004) have shown how to recover mean source electron spectra in solar flares through a physical constraint regularization analysis of the bremsstrahlung photon spectra that they produce. They emphasize the use of non-square inversion techniques, and preconditioning combined with physical properties of the spectra to achieve the most meaningful solution to the problem. Higher-order regularization techniques may be used to generate ${overline F}(E)$ forms with certain desirable properties (e.g., higher order derivatives). They further note that such analyses may be used to infer properties of the electron energy spectra at energies well above the maximum photon energy observed. In this paper we apply these techniques to data from a solar flare observed by RHESSI on 26 February, 2002. Results using different orders of regularization are presented and compared for various time intervals. Clear evidence is presented for a change in the value of the high-energy cutoff in the mean source electron spectrum with time. We also show how the construction of the injected (accelerated) electron spectrum $F_0(E_0)$ (assuming that Coulomb collisions in a cold target dominate the electron energetics) is facilitated by the use of higher-order regularization methods.

description: L'incidence des pratiques culturales employées en culture bananière sur le développement des populations de nématodes a fait l'objet de nombreuses études menées en Côte d'Ivoire. Parmi ces pratiques , trois d'entre elles peuvent avoir des conséquences directes sur le parasitisme. La première concerne le système de culture (période d'abandon des parcelles) et les deux autres concernent la plante (état sanitaire du matériel de plantation et recépage des rejets surnuméraires). Après une période d'abandon de deux ans, une jachère à Asystasia gangetica ou Chromolaena odorata éradique l'espèce Radopholus similis mais maintient les espèces Helicotylenchus multicinctus et Hoplolaimus pararobustus. Seul l'emploi de vitro-plants indemnes de nématodes maintient cet équilibre, alors que l'emploi de souches ou de rejets (matériel infesté) rétablit la population de R. similis. Le recépage des rejets surnuméraires perturbe aussi l'équilibre initial des peuplements puisque R. similis est sensible au stress physiologique causé par la défoliation. Mais son développement est stimulé sur les rejets maintenus comme fructifères. Le développement d'H. multicinctus étant soumis à une compétition interspécifique avec R. similis. il est alors accru sur les rejets recépés.

description: Optical Coherence Tomography (OCT) is an in vivo imaging technique which is able to perform tomographic or crosssectional images of biological tissues. It's main field of application lies in ophthalmology for acquiring 3D volumes of the retina. Thereby unique information about macular diseases such as diabetic retinopathy, or age related macular degeneration can be obtained. However, image contrast may be rather poor in conventional OCT imaging which can be overcome using polarization sensitive OCT (PS-OCT). Another limitation of state of the art is the limited transverse resolution of OCT instruments. The resolution can be improved using adaptive optics. In this thesis an existing adaptive optics-scanning laser ophthalmoscope (AO-SLO) in combination with a time domain OCT (TD-OCT) was upgraded by an additional polarization sensitive channel in order to provide PS-OCT images with cellular resolution. PS-OCT improves the image contrast. Thereby additional information of the retina can be gathered, because several retinal structures (e.g. retinal pigment epithelium) change the polarization state of the light which can be detected using PS-OCT. Furthermore a dynamic focus scheme for achieving isotropic resolution through the whole volume OCT scan was calibrated. To improve the signal-to-noise ratio, the system was partially further developed. The new instrument was tested on technical samples as well as for in vivo retinal imaging. Representative images recorded in healthy volunteers are presented.
G65.2+5.7: A Thermal Composite Supernova Remnant With a Cool Shell

description: This paper presents archival ROSAT PSPC observations of the G65.2+5.7 supernova remnant (also known as G65.3+5.7). Little material obscures this remnant and so it was well observed, even at the softest end of ROSAT's bandpass (~0.11 to 0.28 keV). These soft X-ray images reveal the remnant's centrally-filled morphology which, in combination with existing radio frequency observations, places G65.2+5.7 in the thermal composite (mixed morphology) class of supernova remnants. Not only might G65.2+5.7 be the oldest known thermal composite supernova remnant, but owing to its optically revealed cool, dense shell, this remnant supports the proposal that thermal composite supernova remnants lack X-ray bright shells because they have evolved beyond the adiabatic phase. These observations also reveal a slightly extended point source centered on RA = 19h 36m 46s, dec = 30deg 40' 07'' and extending 6.5 arcmin in radius in the band 67 map. The source of this emission has yet to be discovered, as there is no known pulsar at this location.

How Astronomers Perceive the Societal Impact of Research: An Exploratory Study

description: We present an exploratory study of the perception of professional astronomers about the societal impact of astronomy. Ten semi-structured interviews with astronomers from a range of career and cultural backgrounds have been conducted to gain in-depth insight into their opinion about societal impact and their approach in realising it. The results show that the interviewees are aware of the diversity of impacts that astronomical research has. However, they are mostly active in outreach and only a few activities are incorporated into their jobs to achieve an impact on development. There is little contact with stakeholders in industry, policy or other fields, like development. Besides, a structured approach in their personal outreach is lacking, and assessment is only done informally. Despite the limited sample size of this study, the results indicate that a further change is necessary to engage professional astronomers with topics of development and societal impact to create action on the level of individual researchers.

External membrane bioreactor for the anaerobic treatment of low strength municipal wastewater
Creators: name: Di, Donghong
Publisher: name: University of British Columbia
Year: 2011

description: In this study, the workability of a newly designed anaerobic external membrane bioreactor (AnMBR) was examined. During the acclimatization period, the system was operated at a temperature of 25 to 42 °C and a pH of 6.8 to 7.5. The influent COD was 510 (±13) mg/L. After the acclimatization, the system was maintained at 25 °C and a pH of 6.3 to 7.0. The influent COD was 290 (±18) mg/L. The hydraulic retention time (HRT) was decreased in a stepwise manner from an initial value of 61 hours to 2 hours. As the HRT was decreased, the corresponding volumetric organic loading rate (OLR) was increased from 0.22 ± (0.04) kg COD/m³day to 2.84 ± (0.11) kg COD/m³-day. Results showed that the anaerobic external MBR was capable of treating low strength municipal wastewater under controlled conditions. The COD removal ef ficiencies were 84 (±4) % and 60 (±14) % for the acclimatization period and the steady-state operation period, respectively. The decrease in COD removal efficiency may have been caused by short retention time of organic material in the reactor due to the short HRTs, the inhibition of biomass activity by the high OLR, a decrease of the soluble COD portion of the influent, and the accumulation of VFAs in the reactor. An HRT of 8 hours and OLR of 1.6 kg COD/m³•day was identified as the optimum operational conditions for the system. The permeability of the membrane limited the system treatment capacity. Inorganic membrane permeability was superior to the organic membrane permeability. When operated at trans-membrane pressure (TMP) of 207 kPa and cross flow velocity (CFV) of 3.3 m/s, the organic membrane exhibited high and stable permeate flux. Membrane permeability decreased with an increase of sludge concentration at TMP of 276 kPa, but was independent of sludge concentration at TMP of 83 kPa. Organic membrane cleaning with sodium hypochlorite resulted in an effective flux recovery.

description: As a possible improvement to the United Nations' Human Development Index (HDI), we propose including in the set of individual variables some of an environmental or social nature. Thus, by rescaling all the variables non-linearly it is possible to mitigate the effect of outliers and synthesize by principal components, or alternatively by a different averaging method that takes sustainability into account and penalizes unbalances among different aspects of development. Both methods are easy to implement and calibrate. The ensuing effect on the ranking of world countries is compared to the HDI ranking. JEL Codes: C43, O11, O47, Q01

description: At end-June 2004, the Basel Committee on Banking Supervision finally issued the "New Capital Accord" ("Basel II"), following endorsement by G10 bank supervisors. The Accord replaces the original accord agreed in July 1988 and implemented by most major international banks since 1993. Publication followed years of exhausting work by the Committee to improve upon the original in the light of market developments, advances in risk management and revealed deficiencies in the operation of the current scheme. This article traces the evolution of Basel II, focussing on the post-2000 period. The Impact of the three rounds of consultation on the final shape of the Accord is explored, as is the role played by the Quantitative Impact Studies (particularly, "QIS3"). Finally, Basel II is assessed from a "cost-benefit" standpoint, and outstanding concerns are identified. JEL Codes: G21, G28
