The Cassini Ultraviolet Imaging Spectrograph (UVIS) observed Jupiter in a 4-sec integration "high time-resolution mode" on Jan 8, 13-14, and 20-21 in 2001. In this mode Extreme-Ultraviolet and Far-Ultraviolet spectra were obtained with reduced spectral and spatial resolution in order to study rapid variations in H2 band and H Lyman alpha emission. Previous work has shown that the region inside Jupiter's main auroral ovals contains highly variable spots of emission (auroral flares) that persist for typically 1 or 2 minutes. This duration is similar to that in Jupiter's quasi-periodic (QP) radio bursts. We compare UVIS data to simultaneous Galileo Plasma Wave Subsystem (PWS) and Cassini Radio and Plasma Wave Subsystem (RPWS) observations. Jan 8 was an active period for UV variability, that we associate with polar auroral flares. There is a correlation between the radio and UV bursts in this period, suggesting that they are related phenomena. We will also explore coordinated Hubble Space Telescope Imaging Spectrograph (STIS) time-tagged UV images from Dec 14 and Dec 16, 2000, and Jan 13-14, and Jan 20-21, 2001 to study the spatial properties of the auroral flares. The auroral emissions inside the main oval were most prominent in the Dec 14, 2000 HST data. We acknowledge support from the Cassini Project, the Space Telescope Science Institute, and the NASA OSS Minority University Initiative. [less ▲]

Jupiter was observed by the Chandra X-ray Observatory in late February, 2003, for 144 ks, using both the ACIS-S and HRC-I imaging x-ray cameras. Five orbits of HST STIS observations of the planet's northern auroral zone were obtained during the ACIS-S observations. These data are providing a wealth of information about Jupiter's auroral activity, including the first x-ray spectra from the x-ray hot spots inside the auroral ovals. We will also discuss time variability in the auroral x-ray emission and a possible phase relation between the emission from the northern and southern x-ray aurora. [less ▲]

Typologie des mss qui conservent le répertoire dramatique occitan, établie en se fondant sur la spécificité d’un genre par nature lié à une performance. Dans le cas du théâtre, les données codicologiques (qualité des supports, ajouts marginaux, ratures, présence de notation musicale, de didascalies rubriquées…) sont à considérer en tenant compte de la fonction pratique des mss et du rapport des textes à la scène. L’enquête codicologique éclaire donc l’activité dramatique dans son ensemble (de l’écriture des textes à la conception du spectacle), et ses résultats s’insèrent dans une réflexion plus générale sur le statut littéraire du texte de théâtre occitan au Moyen Âge. Cet article s’inscrit dans l’esprit des recherches menées par G.A. Runnalls sur les mss du théâtre du Nord.] [less ▲]

Original free-surface flow solvers have been developed by the HACH during the last years. The resulting fully integrated WOLF package allows engineers to study a very wide range of free surface flows situations. Successful and accurate computations are performed for phenomena as various as hydrological run-offs and dam breaking in quasi 3 dimensions including solid transport effects, as well as rivers networks modelling with explicit exchanges between river paths. All the models, physically based, use efficient and original numerical methods to solve continuous or discontinuous free-surface flow equations. They handle structured or unstructured grids with both first and second order accurate explicit or implicit algorithms in time and space. WOLF also includes powerful user-friendly pre- and post-processing with 2D and 3D animated visualizations as well as a parameters optimization software interconnected with all the package components and based on the innovating method of genetic algorithms. In this paper, the production of the hydroelectric power plants installed on a 60 km long section of the rivers Amblève and Warche in Belgium is presented in details to illustrate the numerical calculation and optimization process. The river network is modeled using real natural topographic data. Hydrological balance is closed and roughness coefficients are calibrated from water level and discharge field measurements. Hydroelectric production is optimized by an automatic calibration of the parameters of the hydrogram injected in the network from the Robertville dam. This approach leads to a substantial gain in both hydroelectric production and financial benefits and deals with all management and security criteria. [less ▲]

Aerated flow over stepped chutes is principally studied on laboratory models. Consequently, the obtained design relations have a limited field of application. In order to propose a more general description of the flow, a quasi-2D numerical model is developed. The fluid is considered as an air-water mixture governed by the shallow-water equations. Moreover, a transport equation for air concentration represents the self-aeration of the flow and a coefficient of uneven vertical velocity distribution integrates indirectly the turbulent structures. The paper includes a brief description of the flow behaviour, the quasi-2D model equations, and a comparison of the numerical results with the measured flow characteristics in a 30° stepped flume.

The effects of high level of rapeseed meal in the diet on the concentration of antinutritional factors (glucosinolates metabolites) in blood plasma, milk and thyroid were studied in 90 ewes. From the 100th day of gestation, ewes bearing two foetuses were divided into three groups and were fed with pasture hay ad libitum and 500 g/d of diet containing 0 or 40% rapeseed meal obtained from either Apex or Synergy variety. During the 47 first days of lactation, 1200 g/d of the same meal were given. Thereafter, during 3 weeks, the ewes were only fed with hay. Blood and milk samples were taken fortnightly for the determination of SCN- and 5-vinyl-1,3- oxazolidine-2-thione (5-VOT) concentrations. One ewe from each group was slaughtered at the end of rapeseed meal distribution and another one three weeks later for thyroid analyses. SCN- and 5-VOT concentrations in blood plasma increased significantly (P<0.05) and regularly until one month of rapeseed supplementation to the withdrawal of rapeseed in the diet. One to three weeks after the end of rapeseed meal distribution, the SCN- and 5-VOT plasma concentrations came back at the basal level. Some changes were also observed for SCN- and 5-VOT contents in milk. The results indicated a great capacity of the ewes to excrete SCN- and 5-VOT by the milk. A 5-VOT accumulation was observed in the thyroid according to the level of progoitrin in the diet, but no SCN- accumulation. The 5-VOT concentration in thyroid of the ewes fed during three weeks with hay came back to zero. The thyroid analysis showed the reversible aspect of the thyroid hypertrophy due to 5-VOT accumulation. [less ▲]

During the preliminary phase A of the Ground-based European Nulling Interferometer Experiment (GENIE), a number of interferometric configurations have been studied, in the cases of exozodiacal cloud and hot Jupiter detection. Their expected performances have been computed in light of the measured or expected performances of the VLTI sub-systems. A simple Bracewell nulling interferometer, formed of two Unit Telescopes and working in the L' or N bands, has been identified as a good candidate configuration for exozodiacal cloud detection. External or internal chopping, fringe tracking and intensity matching will be critical issues for this configuration. In the case of hot Jupiter detection, a double Bracewell with internal modulation in the L' band seems well appropriate, and should allow to carry out low resolution spectroscopy on a few bright exoplanets. The basic assumptions and computations which have lead to these candidate configurations are described in this paper. [less ▲]

This paper describes the implementation of an online transient stability assessment software, composed of algorithms for contingency screening and for the design of preventive control actions. The implementation of the two parts rely on a hybrid method called SIME, coupled with a time domain simulation engine and power flow program. The speed up of the contingency screening module is obtained by distributing contingencies on a cluster of computers to comply with extended real-time speed requirements. A compensation scheme is used to determine active power rescheduling alternatives in order to stabilize the dangerous contingencies identified at the screening step. The software has been coupled with an industrial EMS platform, and tested in the simulation environment. [less ▲]

The Gravettian tradition appears to develop from local Mousterian and different cultures at the beginning of the European Upper Palaeolithic (Chatelperronian in the west, foliate points in the north and the Streletskaian in the east). New technological characteristics proper to the Gravettian developed in different regions of middle Europe, apparently around the same time: thin, standardised blades, development of small backed armatures. The Gravettian is thus a pan-European phenomenon, extending across middle Europe, but developing locally. Development within the Gravettian is quite complex, with regional areas of expansion of processes varying according to the phase or facies considered. The Moldavian sequence is key to understanding the regional development of the Gravettian. It can be integrated with that of central and eastern Europe. General developmental tendencies appeared here, connecting regional patterns with traditional roots. The Gravettian culture can thus be considered a collection of technological processes probably adopted by diverse ethnic groups which nevertheless were in regular contact. During the Second Pleniglacial, important climatic changes provoked a division between central and western groups, leading to profound differences between south-eastern Europe (Ukraine, the Carpathian region, the Balkans) and western Europe (Solutrean-Magdalenian succession).

Chalk is the constituent material of numerous oil reservoirs in North Sea. The mechanical behaviour of a saturated chalk has been largely studied. However, different aspects of its behaviour are not yet well understood: material characteristics depend on the saturating fluids and chalk response is time-dependent. This paper proposes the PASACHALK numerical model: an elasto-plastic constitutive law is presented, which reproduces the different plastic mechanisms of the chalk (pore collapse and shear failure) and the influence of pore fluids. The water sensitivity of this soft rock is explained by the existence of suction effects in chalk. Finally, a simulation of a hypothetical reservoir is proposed to show the response of the elasto-plastic model during depletion phase and water injection phase. [less ▲]

For easier handling and use in fixed bed reactors, Pd-Ag/SiO2 aerogel-like xerogel catalysts were shaped into microspheres using the microencapsulation process developed by BRACE GmbH. Before the bead production process, the xerogel catalyst was ground in water and mixed with ethylene glycol and sodium alginate, the latter of which is the gelation agent. The beads were formed at a vibrating nozzle and solidified during their fall in a water tank containing calcium ions, which induce cross-linking of the alginate and consequent bead hardening. Preliminary work was done using a syringe instead of the material-consuming BRACE unit. The beads were made from a suspension of dried only, dried and calcined, or dried, calcined, and reduced catalyst. The textural properties of the beads were analyzed by nitrogen adsorption-desorption isotherms and mercury porosimetry; and bead catalytic activity was tested for selective hydrodechlorination of 1,2-dichloroethane. The beads made from a suspension of dried catalyst appear to have properties the closest to that of the xerogel reference catalyst. Porosity and surface area are maintained at their level before bead formation. However conversion of 1,2-dichloroethane decreases after the production process, possibly due to poisoning by calcium ions. (C) 2004 Elsevier B.V. All rights reserved. [less ▲]

The state of Minas Gérais, Brazil, contains numerous karsts booth inside carbonated and non carbonated rocks. Différent caves are found in quartzite and Itaberite formations (Banded Iron formation). The term karst is used in the meaning of "any features of the classical karst morphology (caves, sink-holes, lapies...) where dissolution plays the main genetically action and this in any kind of rocks". In some areas, lapiaz and kamenitza affect wide landscapes (area of Diamantina, Natural Parc of Rio Preto). Several caves are found and some of these are several kilomeetres long (grutta do Bromelias, Natural Parc of Ibitipoca). Inside caves, we found numerous forms like dissolution alveoli, spelothems, .... Many times, the cave sides and solutional forms are covered by crust which solidify a very crumbly quartzite. Différent morphologies show an primary solutional stage of the rocks before a physical erosional stage which destroy the earliest forms (piping, river érosion, collapsing). [less ▲]

Great concern raised from the populations decline observed for the harbour porpoises in the North Atlantic but Norwegian populations remain poorly characterized. Trace elements concentrations (Zn, Cu, Cd, Se, total Hg) have been determined in liver, kidney and muscle of 23 harbour porpoises (Phocoena phocoena) caught in fishing nets along the Norwegian coast. Sources of variation have been examined with a special interest on geographic location and diet modifications analysed through stable isotopes of carbon (δ13C) and nitrogen (δ15N). This study further intend to complete previous feeding ecology knowledge with a combined approach of stable isotopes ratios and metals concentrations as dietary tracers. Norwegian porpoises display mean hepatic concentrations of Zn, Cu and total Hg (96 ± 18; 25 ± 6 ; 15 ± 10 µg.g-1dw respectively) among the lowest in the North-Atlantic. These results suggest that porpoises from this region are less exposed to these metals than others sites such as the North Sea. The low burdens of certain metals (Zn, Cu, Hg) observed make the Norwegian populations suitable to be used as reference level for future ecotoxicological studies on this species. However, renal Cd concentrations (6.7 ± 4.1µg.g-1dw) are twice higher than those from the Southern North Sea. They probably reflect dietary modifications of the porpoises through their range. The low isotopic composition (mean muscle values: d13C=-18.5 ± 0.6 0/00 and δ15N=13.5 ± 1.2 0/00) suggests that Norwegian porpoises feed on more oceanic preys as confirmed by variations of hepatic Hg and renal Cd concentrations. Given that teutophagous marine mammals present higher concentrations of Cd than piscivorous ones. The results obtained lead to the conclusion that the Norwegian porpoises rely on more oceanic squids than those from the North Sea. [less ▲]

A coordinated action involving eleven stations of the ground -based Network for Detection of Stratospheric Change (NDSC) equipped with Fourier transform infrared (FTIR) instruments was conducted to contribute to the validation of the three atmospheric chemistry instruments onboard ENVISAT, that are MIPAS, SCIAMACHY and GOMOS. The target products for validation are total columns of O3, CH4, CO and some important NOy species (NO2, HNO3, NO) and the source gas N2O. Together the eleven stations cover the latitudes between 79 °N and 78°S, including polar, mid-latitude and subtropical and tropical locations. The goal is to contribute to the assessment of the data quality of the aforementioned ENVISAT instruments, from a quasi -global perspective. The period of intensive ground-based data collection for the benefit of the ENVISAT Validation Commissioning Phase that is dealt with in the present paper is July 15 to December 1, 2002. The FTIR network involved collected a data set corresponding to an equivalent of approximately 400 days of measurements; about three quarter of the data have already been submitted to the ENVISAT Calval database and are included in the present work. Unfortunately, the distribution of ENVISAT data has been slow and limited. Only a limited number of coincidences has been found for making data inter -comparisons. Therefore, the conclusions drawn in this paper are very preliminary and cover only a limited set of data products from SCIAMACHY only. Our findings up to now concerning the above mentioned target products are the following: (1) SCIAMACHY near infrared operational products (CO, CH4, N 2O) have no scientific meaning yet, (2), the operational SCIAMACHY total vertical O3 column product derived in the ultraviolet window has undergone some improvements with changing versions of the processor(s) but it still underestimates the column by about 5 – 10 %, (3), the operational SCIAMACHY total vertical O3 column product derived in the visible window is unrealistically large, and (4), the operational NO2 total column product from SCIAMACHY seems to largely overestimate the real column, but very few coincidences and large dispersions of the data do inhibit any further conclusion at present. In a next phase, the same ground-based correlative data set will be exploited to further validate the ENVISAT data as soon as more and reprocessed data will be distributed. [less ▲]

Since the middle of the 20th century, the University of Liège has been active at the International Scientific Station of the Jungfraujoch (ISSJ) in the Swiss Alps (46.5°N, 8.0°E, 3580m asl) to study the chemical composition of both the solar photosphere and the Earth’s atmosphere. Since 1989, the ISSJ is an accepted site of the northern midlattitude primary Alpine station of the NDSC (Network for the Detection of Stratospheric Change). This acceptance resulted from earlier monitoring activities by Ulg of a large number of atmospheric constituents. Within the NDSC frame, a special attention and many efforts have been devoted to the monitoring of the most important atmospheric constituents involved both in the erosion of stratospheric ozone and in the greenhouse capacity of the troposphere, after it became clear that human activities have a direct impact on these two processes. Using two high resolution Fourier transform infrared (FTIR) spectrometers, over 25000 wide-band solar spectra encompassing nearly 1700 days since the mid 1980s have been recorded and analyzed to study, quasi simultaneously and repeatedly, local, seasonal and secular variations of some 20 gaseous telluric species. So far, most results have been reported, demonstrating the power of infrared spectrometric solar observations to characterize the chemical composition of the atmosphere. These datas, archived in terms of total vertical column abundances (e.g., at the NDSC-Data Host Facility; http://www.ndsc.ws), are expressed in number molecules per cm2 above the site using best-know input parameters (i.e. spectroscopic-, instrumental-, environmental-) in the retrieval procedure. Meanwhile, more sophisticated algorithms, based on the “Rodgers” optimal estimation method, have been developed, allowing to derive partial tropospheric- and stratospheric columns for various species, including HCl, ClONO2, O3, HF, CO, N2O, CH4, HCN, OCS. This contribution reports related results for HCl and ClONO2. [less ▲]

Growing concern has been raised about the status and the long-term viability of the harbour porpoise (Phocoena phocoena) in the North Sea and adjacent areas. Sources of trace metal variations were investigated using a multidisciplinary approach. Porpoises from the Belgian coasts were compared to individuals from the German North Sea and Baltic coasts, Denmark, Norway and Iceland. Toxicological results (Hg, Zn, Cu, Cd and Se) were confronted to most common pathological findings, namely emaciation, lesions of the respiratory system or parasitism. Influence of diet through stable carbon and nitrogen analysis (d13C and d15N), age and sex have also been considered. As expected, the nutritional status of stranded harbour porpoise from the Southern North Sea is poor compared to by-caught individuals from Norway and Iceland, as reflected by their blubber thickness, weight to length ratio and hepatic to total body mass ratio. The porpoises collected along the Southern North Sea coast display higher Zn and Hg concentrations compared to individuals collected in more preserved areas from the North Atlantic. Moreover, significant Zn, Hg and Se levels were observed with increasing emaciation severity. Porpoises displaying severe bronchopneumonia also have higher Zn concentrations probably due to the association previously described of emaciation and bronchopneumonia. Hg is clearly linked to parasitism. These increasing concentrations are not related to a shrinking of liver mass as it remains unchanged during the emaciation. As a result, hepatic trace metal load increases also. These observations tend to indicate a general redistribution of heavy metals within the organs (muscles to livers), which results from protein catabolism. Such a re-distribution could well be an additional stress for porpoises already experiencing stressful conditions (organochlorines, etc…). In contrast, Cu and Cd were never associated to emaciation. Other parameters such as age class or diet are more likely to be involved. [less ▲]

Die Referentin, selbst Sprachberaterin, versteht die individuelle Beratung bei der Textrezeption und -produktion als eine Chance zum lebendigen Austausch zwischen Linguisten und Nichtlinguisten. Individuelle Sprachberatung ist mehr als eine Übersetzung linguistischer Erkenntnisse für Laien. Die Bereitschaft der sprachberatenden Linguisten zur Beeinflussung der Textproduktion setzt voraus, dass eine „reine“ Deskription sprachlicher Phänomene als Utopie bzw. als ein genuin monologisches Verfahren der Grammatikographie erkannt wird. Ob das Gespräch den Sprachberatungskunden letztlich dazu anregt, „wegen des Wetters“ zu schreiben oder „wegen dem Wetter“ – in jedem Falle haben Berater und Kunde auf der Grundlage empirisch gewonnener und deskriptiv ausgewerteter Daten gemeinsam eine Norm formuliert. Sprachberatung kann aber auch nachgerade in der Werbung für die Utopie einer reinen Deskription bestehen, selbst wenn der ursprüngliche Anlass des Gesprächs die Suche nach einer möglichst strengen Norm gewesen ist. Nicht nur wie sprachliche Zweifelsfälle und mögliche Lösungsansätze dargestellt werden, sondern auch welche Fakten präsentiert werden, hängt von einer Reihe spontan – das heißt: in Sekundenschnelle – getroffener Entscheidungen beider Gesprächspartner ab. Bereits beim ersten Kontakt (Begrüßung; Formulierung der Frage) ordnet die Sprachberaterin ihren Gesprächspartner einer Gruppe von Sprachteilnehmern zu und macht sich ein Bild von der Situation, in der dieser Zweifelsfall aufgekommen ist. Von der Bewertung dieser Gesprächssituation hängt es ab, ob die Antwort in einer schnellen impliziten Handlungsanweisung besteht („Der Satz ist korrekt“) oder ob Grundfragen der Linguistik wie die Definition des „Standards“ im Varietätenspektrum, quantitative und qualitative Methoden in der Korpusauswertung, vielleicht sogar sprachphilosophische Fragen thematisiert werden. Im Vortrag sollen am Beispiel einiger Zweifelsfälle aus dem Bereich der Syntax (Moduswahl, Substantivvalenz, Monoflexion) situationsgerechte Gesprächsziele und -strategien herausgearbeitet und zur Diskussion gestellt werden. Neben dem Erkenntnisinteresse und den Gesprächszielen der Anrufer wird das Erkenntnisinteresse der Linguisten zu bedenken sein. Paradebeispiel hierfür ist die Frage, inwiefern die gängigen mehr oder weniger verbzentrierten Grammatikmodelle der Produktion konzeptionell schriftlicher Texte angemessen sind. [less ▲]

The paper discusses the components of reduction factor to be accounted for design purposes. A parametric study of moment resisting steel frames (MRSF) designed according Eurocode 3 (EC3) and Eurocode 8 (EC8) is performed. The structural supply of the designed structures exceeds largely the seismic demand in spite of the fact that Ultimate Limit State (ULS) verification of EC8 for MRSF is not conservative. The structural performance is poorly correlated with ULS verification of EC8 but with others code restrains and with parameters like base shear ratio or fundamental period. The practice that deduces the values of reduction factor on the observation of structural performance under past earthquake is not rationally based. This practice tends to make useless the ULS verification for structural systems like MRSF, in which structural performance is poorly correlated with the ULS verification. This practice is responsible of the unsafe values of reduction factors assigned in the seismic codes. [less ▲]

In Belgium, the Boom Clay is being considered as a potential host formation for the disposal of nuclear waste. Part of the safety assessment and feasibility studies of a potential nuclear waste disposal consists of hydrogeological modeling. In order to model the groundwater flow and possible radionuclide transport in the clay, the spatial distribution of the hydraulic conductivity of the clay has to be assessed. In this study, geostatistical methods are used to characterize the hydraulic conductivity field. More specific, direct sequential simulation of the hydraulic conductivity is carried out, using measurements of hydraulic conductivity and 4 types of soft data or secondary variables: resistivity logs, gamma ray logs, grain size measurements and descriptions of the lithology. The primary and secondary information is analyzed with geostatistical tools and combined to generate 100 fields of the hydraulic conductivity of the Boom Clay. Next, each field is input to a groundwater flow model to predict the advective travel time of constituents released from the disposed waste in the Boom Clay to the aquifers surrounding the Boom Clay. Statistical analysis of the ensemble of model predictions results in a predictive distribution for the advective travel time. This distribution reflects the uncertainty of the advective travel time that results from the uncertainty of the spatial distribution of the hydraulic conductivity of the Boom Clay [less ▲]
