This paper is concerned with the numerical simulation of hot metal forming, especially superplastic forming. A complete thermo-viscoplastic formulation at finite strains is derived and a unified stress update algorithms for thermo-elastoplastic and thermo-elastoviscoplastic constitutive equations is obtained. The resulting unified implicit algorithm is both efficient and very inexpensive. Finally, numerical simulations of superplastic forming are exposed. [less ▲]

This paper considers finite-automata based algorithms for handling linear arithmetic with both real and integer variables. Previous work has shown that this theory can be dealt with by using finite automata on in finite words, but this involves some difficult and delicate to implement algorithms. The contribution of this paper is to show, using topological arguments, that only a restricted class of automata on in finite words are necessary for handling real and integer linear arithmetic. This allows the use of substantially simpler algorithms and opens the path to the implementation of a usable system for handling this combined theory. [less ▲]

The definition of the term cryptospore is amended to include only spores thought to be produced by embryophytes and to exclude all enigmatic palynomorphs. Cryptospores are included here in the miospore group.The oldest published assemblage of typical cryptospores is Llanvirn in age. The evolution of cryptospore assemblages is very slow from the Llanvirn to the early Llandovery. The Telychian and Sheinwoodian stages are periods of drastic impoverishment in cryptospore biodiversity, followed by an important modification in miospore assemblages. This step in the evolution of the vegetation is correlated with the rapid transgression of seas on the continent during the early Llandovery. On the other hand, the Hirnantian glaciation does not affect diversity of the miospore assemblages. [less ▲]

La simple exposition répétée à un stimulus conduit les sujets à préférer ce stimulus par rapport à des stimuli non présentés. Nous avons exploré cet effet chez 22 sujets âgés (de 60 à 70 ans) et 22 sujets jeunes (de 20 à 30 ans) appariés quant au niveau d’éducation. Dans une première phase, on demande aux sujets d'estimer l'âge de 15 visages-cibles, non familiers. Ces 15 visages sont présentés durant 15 msec., cinq fois dans un ordre aléatoire. Ensuite, on présente aux sujets 15 paires de visages (un visage-cible et un visage non présenté) et on leur demande de choisir le visage qu'ils préfèrent. Enfin, un test de reconnaissance leur est administré. En ce qui concerne le jugement de préférence, les sujets âgés et les sujets jeunes choisissent préférentiellement le visage exposé antérieurement, avec une performance supérieure au hasard. De plus, la performance des deux groupes ne diffère pas significativement. Par contre, la performance des sujets âgés en reconnaissance est significativement inférieure à celle des sujets jeunes. En conclusion, ces résultats indiquent que les processus sous-tendant l'effet de simple exposition sont préservés par le vieillissement en dépit d'une reconnaissance explicite déficitaire. [less ▲]

We describe an active application in the field of multicast congestion control for real-time traffic. Our Active Layered Multicast Adaptation Protocol is a layered multicast congestion control scheme built on top of an Active Network infrastructure. It benefits from router support in order to obtain information about resources available and to perform the adaptation tasks at the places where shortage of resources occur. It supports heterogeneous receivers through the combination of layered multicast transmission with selective filtering and pruning of layers within the active nodes. Market-based resource management ideas are applied to achieve a resource utilisation level that represents an equilibrium between the user goals and the node operator goals. Our simulation results show that the protocol is feasible and provides adequate reactions to short term and persistent congestion, while keeping the amount of state and processing in the active nodes limited.

In order to accommodate fluctuations in network conditions, adaptive applications need to obtain information about resource availability, Using active networks, new models for adaptive applications can be envisaged, which can benefit from the possibility to send mobile code to the network nodes. We describe a model for trading resources inside an active net-work node, based on the interaction between capsules as reactive user agents, and resource manager agents which reside in the network nodes. We apply the model to the case of a many-to-one audio application with congestion control, which trades off link resources against memory when there is congestion at the outgoing interface towards the destination. Our simulation results indicate that the application makes effective use of the available resources, and it also allows resources to be shared according to user preferences. [less ▲]

In the framework of a North Sea and adjacent areas monitoring, metallothioneins (MTs) have been studied in livers and kidneys of 8 marine mammals species collected on the Belgian coast and in the Northeast Atlantic between 1993 and 2000: the harbour porpoise Phocoena phocoena , the harbour seal Phoca vitulina, the white beaked dolphin Lagenorhynchus albirostris, the white sided dolphin Lagenorhynchus acutus, the sperm whale Physeter macrocephalus, the fin whale Balaenoptera physalus, the common dolphin Delphinus delphis and the striped dolphin Stenella coeruleoalba. The participation of this protein in metal detoxification has been investigated since high levels of cadmium (Cd) and mercury (Hg) have been measured in livers and kidneys of those marine mammals. It appears that MT concentrations vary widely in marine mammals tissues (from 50 to more than 2000 µg.g–1 dw) underlying the numerous parameters involved: species, tissue, physiological status, pregnancy, age, diet and metal level. The percentage of the cytosolic Cd bound to MTs can reach almost 100%. On the contrary, the percentage of hepatic and renal Hg bound to MT is very low (generally less than 10 %) and this metal is mainly associated with selenium (HgSe) under a detoxified form in the insoluble fraction of the tissues. Characterisation of renal MTs of white-sided dolphin has been performed: the protein has two isoforms (MT-1 and MT-2) with a molecular weight estimated around 6800. MT-1 can bind Cu, Zn, Hg and Cd while MT-2 only binds Zn, Hg and Cd suggesting different metabolic functions for the two isoforms. MT-2 was also more abundant than MT-1. To conclude, MTs appear to play a minor role in the binding and detoxification of Hg by marine mammals. On the contrary, close and dynamic interactions occur between Cd and MTs. White-sided dolphin metallothioneins has two isoforms likely characterised by different metabolic functions in relation with cellular homeostasis and cadmium detoxification. [less ▲]

This paper presents an overview of algorithms for constructing automata from linear arithmetic constraints. It identifies one case in which the special structure of the automata that are constructed allows a linear-time determinization procedure to be used. Furthermore, it shows through theoretical analysis and experiments that the special structure of the constructed automata does, in quite a general way, render the usual upper bounds on automata operations vastly overpessimistic.

We show that the synthesis conditions have a dramatic influence on the resistivity behavior of calcium and sodium doped LaMnO3. Several samples prepared by lowtemperature techniques exhibit a double-peaked curve of resistance versus temperature. The model of spin-polarized intergranular tunneling provides a good approach to discuss our experimental results. Grain size and crystallinity are proved to be essential parameters, which are strongly influenced by the preparation process (e.g. the precursors nature and the thermal treatment). [less ▲]

L'assistance technique dite «programme de stewardship» a été initiée par les donateurs au Rwanda en 1998, avec l'aide du Consortium IPHYTROP, conformément aux «Lignes directrices sur l'aide et l'environnement N"6" de l'OCDE (1995). Elle vise à accompagner les achats de pesticides et à responsabiliser tous les acteurs de la filière et en priorité les producteurs. Pour la première fois durant la campagne 1999/2000, au Mali, au Burkina Faso et au Tchad, un programme de stewardship complet destiné aux utilisateurs de pesticides a été réalisé dans le cadre des Appels d'Offres pour l'achat des produits phytosanitaires. Ce programme, financé par SENCHIM-AG, a été proposé afin d'apporter d'une part, un complément de formation technique en matière de lutte phytosanitaire et d'autre part, de communiquer sur le terrain aux encadreurs et aux agriculteurs les éléments essentiels sur les produits fournis et à les conscientiser quant aux risques liés à l'utilisation des produits phytosanitaires (insecticides, herbicides, fongicides). C'est l'intérêt de tous les acteurs d'accompagner désormais systématiquement les livraisons de produits phytosanitaires de tels programmes de formation. L'article se propose d'exposer le programme réalisé, les. contraintes rencontrées et les enseignements tirés de ces trois premières expériences. [less ▲]

Remote sensing of Jupiter's aurora from x-ray to radio wavelengths has revealed much about the nature of the jovian aurora and about the impact of ionosphere-magnetosphere coupling on the upper atmosphere of Jupiter, As indicated by the combination of x-ray and ultraviolet observations, both energetic heavy ions and electrons energized in the outer magnetosphere contribute to auroral excitation. Imaging with the Hubble Space Telescope in the ultraviolet and with the InfraRed Telescope Facility at infrared wavelengths shows several distinct regions of interaction: 1) a dusk sector where turbulent auroral patterns extend well into the polar cap; 2) a morning sector generally characterized by a single spatially confined auroral are originating in the outer or middle magnetosphere of Jupiter; 3) diffuse emissions associated with the Io plasma - spectroscopy has provided important information about the thermal structure of Jupiter's auroral atmosphere and the altitude distribution of auroral particle energy deposition, while Lyman alpha line profiles yield clues to the nature of thermospheric dynamical effects. Galileo observations at visible wavelengths on the nightside offer a new view of the jovian aurora with unprecedented spatial information. Infrared observations have added much to the understanding of thermal structure at all latitudes, the dynamics of the thermospheric wind system, and auroral morphology, and may hold the key to understanding the role of Joule heating in Jupiter's thermosphere. ROSAT observations have revealed soft x-ray emissions from Jupiter's lower latitudes as well as from the auroral zones, implying that energetic particle precipitation also occurs at low latitudes in regions magnetically linked to the inner radiation belts. In this review, multispectral observations of jovian auroral emissions are presented within a theoretical/modeling framework that is intended to provide some insight into magnetosphere-ionosphere coupling and its effects on the upper atmosphere.

High pressure treatments produce gelified chicken meat patties with new properties thigh water retention and cohesive texture) and without salt or fat addition. In comparison with heat-induced patties, the pressurised patties present an equivalent hardness with better water binding properties. Pressurisation causes an increase of the colour lightness parameter (L*) and a decrease of redness (a*) and yellowness (b*); but the meat discoloration provoked by the pressure treatments is less significant than the colour changes induced by heating. The pressure-gelation of chicken meat patties is affected by the intensity, the duration and the temperature of the process. The elevation of pressure from 400 to 600 MPa enhances the texture qualities and the water binding capacity of formed gels. A positive effect on texture quality. is observed by prolonging the pressurisation time up to 30 min. The pressurisation temperature (between 15 and 40 degreesC) has no effect on product quality. Addition of salt (fat) prevents (reduces) the gelation ability of meat patties under pressure, whereas it improves the texture of heat-induced gels. [less ▲]

The study concerns the application techniques of agrochemical products and especially focuses on the wear of spraying nozzles. This one leads to a modification of the spraying characteristics and the homogeneity of distribution deteriorates. An accelerated wear process of nozzles is defined by the standard ISO 5682-1, which makes it possible to compare the wear resistance of the different nozzles available on the market. In order to accelerate the process, an erosive suspension is used in the test rig, but this suspension looses its characteristics during the utilisation time. This is the reason why a system measuring continuously the erosive power has been set up. This system is validated by different discontinuous measurement and the correlation observed have a coefficient of about 0,99. From the signal detected by the new device, two calculations have been carried out. A first one determining continuously the total wear quantity of the nozzles. A second one identifying continuously the erosive power of the suspension. On the one hand, we obtain a basis allowing to compare the wear resistance of nozzles and on the other hand, a parameter indicating the appropriate time to change the suspension. [less ▲]

The purpose of the study was to examine the relationship between in vivo and ex vivo quantitative ultrasound (QUS) measurements with and without soft tissue and ex vivo dual X-ray absorptiometry (DXA) at different aspects and levels of the third metacarpal bone (MC III) in horses. Both MC III of 8 clinically normal horses were divided in 9 sites (lateral, medial, dorsal aspect; proximal, mid, distal level). Speed of sound (SOS) measurements were performed with a QUS multisite device (Sunlight Ltd., Rehovot, Israel) and a DXA device (Hologic Inc., Bedford, USA) was used to evaluate cortical bone mineral density (BMD) at each site. Ex vivo data on MC III were analysed with a mixed model to test the hypothesis of no difference between aspect and level in QUS and DXA while adjusting for fixed member and for random horse effects. Pearson correlation coefficients between SOS and BMD obtained on MC III with soft tissue were calculated for each member and site. A mixed model was used to determine whether there is a difference between in vivo and ex vivo SOS data while adjusting for fixed aspect, level, and member and random horse effects. Highly significant (p<0.001) differences were obtained between aspects for ex vivo SOS and DXA measurements. Differences (p<0.001) were obtained between measurement levels for DXA data. The table shows least squares means (LSM) and standard errors (Std Err) for QUS and DXA measurements performed at different aspects. The correlation coefficient between SOS and DXA over all 9 sites and both MC III was negative (r=-0.28; p<0.001). In vivo and ex vivo SOS data were different (p<0.01) BUT NOT EX VIVO DATA WITH AND WITHOUT SOFT TISSUE (P>0.05). The study suggests that, in horses, SOS results can not be explained only by BMD, but could reflect additional properties of bone, such as elasticity, architecture or bone strength. Our results indicate that soft tissue does not influence ex vivo SOS measurement results. [less ▲]
