Unimolecular reactivity of ionized difluoroethylene and vinylbromide have been investigated using photoionization mass spectrometry and tandem mass spectrometry. Kinetic energy release distributions corresponding to HF- and F- losses from 1,1-C2H2F2+ and to Br-loss from C2H3Br+ have been determined. At low internal energy the loss of HF from C2H2F2+ leads to the fluoroacetylene cation with a large kinetic energy release (0.4-2.5 eV) while at higher energy a new channel is opened, leading to C=CHF+ (fluorovinylidene) with a much smaller kinetic energy release (0.0-0.2 eV). For the F-loss from C2H2F2+ and the Br-loss from C2H3Br+ bimodal distributions have been observed. The possible role of excited states in these dissociations is discussed. [less ▲]

We have analyzed high resolution and high signal-to-noise spectra of about 20 metal-poor stars. The correlations between the relative abundances of 16 elements have been studied, with a special emphasis on the neutron-capture ones. This analysis reveals the existence of two sub-populations of field halo stars, namely Pop IIa and Pop IIb. They differ by the behaviour of the s-process elements versus the alpha and r-process elements. We present a scenario for the formation of these stars, which closely relates the origin of field halo stars to the evolution of globular clusters. According to this scenario, the two sub-populations originate from two different stages in the globular cluster's chemical evolution. In the first stage, the massive stars of the globular cluster's first stellar generation evolve, ending their lives as supernovae and ejecting alpha-elements and r-process elements into the interstellar medium. A second generation of stars forms out of this enriched ISM. In the second stage, the intermediate mass stars reach the end of the main sequence and the AGB stage, ejecting s-elements into the ISM through stellar winds or superwinds events. The matter released in the ISM by the AGB stars will be accreted by the lower-mass stars, enriching those stars in s-elements and accounting for PopIIb stars. We calculate the rates of interstellar gas production by stellar winds and the rates of gas accretion to estimate the changes in the globular cluster stars abundances. We compare those results to our observations. [less ▲]

Much progress has been made through this half century in the search of driving mechanisms and selection of modes. After a short historical account tracing the steps already taken in the early days of stellar stability, quasi-adiabatic and non adiabatic oscillations are described with an emphasis on the physical meaning of the stability coefficient. A simplified picture is presented for the major driving mechanisms. Applications for the major classes of variables stars are reviewed with the problems encountered during this half century and some of the various remedies that have been proposed. At each step, a special care is given to Art CoxUs important contributions. [less ▲]

A management of nitrogen fertilizers and a conversion of cropping soil into fallow were developed to reduce the nitrate pollution of spring exploit to supply with drinking water the southwestern Luxembourg. The methodological approach was based on in situ observations and includes a study of nitrates lost by leaching (measure of nitrogen profiles in experimental fields, use of vertical soil water cup ceramics) and study of the water quality of springs (measurements of nitrate concentrations). Since October 1995, the nitrate concentrations of polluted springs have been reduced by 25 mg l-1 due to the fallow and the reduction of nitrogen fertilizers. [less ▲]

Le groupe « Formation des Utilisateurs » des bibliothèques et centres de documentation est un groupe de travail autonome de l’Association Belge de Documentation (A.B.D.), créé en 1989 suite à une prise de conscience des difficultés rencontrées par les utilisateurs, étudiants et professionnels, confrontés à leur recherche d’informations. Pour évaluer l’état de la formation des utilisateurs de bibliothèque en Belgique, ce groupe a adressé début 1995, un questionnaire à 1500 bibliothèques belges, francophones et néerlandophones, publiques, d’enseignements et d’entreprises. Les finalités, les aspects techniques et les composantes pédagogiques de prise et de traitement d’informations étaient envisagés. 210 bibliothèques ont répondu. Ceci nous a permis de dresser une photographie nuancée de la formation des utilisateurs de bibliothèques en Belgique, en particulier dans ses axes techniques mais aussi méthodologiques (identification des besoins documentaires, exploitation et critique de l’information). Ont également été traités les aspects axiologiques, le degré d’intégration dans le cursus scolaire, les liens avec les nouvelles technologie de l’information et les freins rencontrés... La présentation des résultats de cette enquête dans le cadre du panel « Vue d’ensemble de la formation documentaire dans les différents contextes de l’Europe, de l’Afrique, de l’Amérique du Nord » devrait permettre une mise en relief des pratiques belges à la lumière d’expériences étrangères et la stimulation du travail de réflexion de notre groupe.

The Jackson Model allows to estimate daily actual evaporation from the integrated daily net radiation and from the difference between surface temperature and air near-midday. Accepting a few assumptions and after mathematical manipulations of the initial model, the daily evapotranspiration can be obtained if the near-midday instantaneous sensible heat fluxes and the daily and near midday net radiation are known. This paper focus on the estimation of the instantaneous sensible heat fluxes. Two approaches are used to estimate them : the first uses a classical approach which represents the surface with a homogeneous single layer. The second model approximates the surface with a double-layer. In the latter model, one layer represents the soil and herbaceous vegetation while the second layer is assumed to represent the foliage of trees or shrubs (high vegetation) depending on the site. Finally, this double-layer model is simplified to allow its use by remote sensors observations. These three models are compared with field measurements during the Hapex-Sahel 92 experiment in Niger. The results show that the classical one-layer model is unable to express the latent heat fluxes of this sparse vegetation while the two double-layer models appear promising and need further developments.

Hot compression tests at constant strain rate and temperature allow to reach stress-strain curves. These experimental data are then used to calibrate a Norton Hoff elastoviscoplastic model (Gavrus & Massoni 1995). The implementation of this model (Habraken et al. 1997) in the large strain non linear finite element code LAGAMINE is summarised in this paper. Then finite element thermo-mechanical analysis of previous compression tests and independant ones are performed to validate the produced material constitutive model. These simulations give the stress, strain rate and temperature fields of the sample, necessary to predict recrystallisation phenomena. A summary of the recrystallisation models proposed by the literature as well as the simple one implemented in the LAGAMINA code will be presented. So experimental, numerical and metallographic studies of hot compression tests aim the definition of an accurate predictive thermo-mechanic metallurgical model able to simulate forging processes.

Two ferrous matrix, a high speed steel and a maraging steel has been reinforced with alumina, titanium and vanadium carbides. The composite was realized by powder metallurgy.The particles were mechanically mixed with the prealloyed powder before compaction. To optimize the composite properties, the processing parameters (i.e. prealloyed powders, size, mixing conditions, temperature of sintering, e..) and the effect of reinforcement (size and composition of particles, volume, fraction, ..) were studied. It is necessary to obtain a full density with the minimum porosities and to control boht the size, the distribution and the dispersion of the reinforced particles. The optimal sintering temperature depends on the reinforcement particles used and is of great importance for the properties. Processing parameters (mixing of particules) can greatly affect the final properties. It has been showed that the use of M203 increases the wear resistance in the two matrix. [less ▲]

Some trials with graphite Hi-Cr iron rolls have been done mainly in Japan, for the rolling of stainless steel. This material could lead to good compromise between oxidation, wear and thermal behaviour. By using thermal analysis and resistometry, the conditions for secondary graphite formation have been studied. The amount and volume of free graphite may be strongly increased by a suitable heat treatment, allowing a good thermal conductivity as well as high wear and mechanical properties. [less ▲]

There is a general interest to consider stress constraints in topology optimization of continuum structures. By their very nature stress constraints are local constraints which result in large scale optimization problems that are often expensive to solve. Here in order to reduce the computing the effort we explore an alternative technique based on equivalent global (that is integrated) constraints. We define two global stress constraints based on the p-norm and p-mean of the epsilon-relaxed overall stress criteria in the finite elements. We present a new formulation of the epsilon-relaxation technique which is better suited to topology optimization of continuum structures and which makes the relaxation process automatic. The "p-mean" and "p-norm" functions bound by lower and upper value the maximum value of the epsilon-relaxed overall stress criterion. Based on numerical experiments this study compares the global and the local constraint formulations. Even if the use of integrated constraints leads a reduction of the computing time by one or two orders of magnitude, they definitely give a weaker control of local stress level. This sometimes can lead to solutions that are a bit different. [less ▲]

In fissured and slighly karstified chalks, the main difficulty for modelling groundwater flow and transport consists in finding a good approximation of the highly heterogeneous reality by a REV concept. No major problem is encountered for groundwater flow simulations when the high contrast in hydraulic conductivity can be given to the cells/elements of the model. The Darcy’s law is applied in terms of specific flow rate, through the REV. When considering transport, it is often assumed that the calibrated field of hydraulic conductivity should be kept unchanged. Consequently, ‘physically non acceptable’ values of the effective porosity are often needed to obtain a match between modelled and measured breakthrough curves. The model becomes, to some extent, a black-box model. [less ▲]

Au cours de la dernière décennie, le rendement des cultures de blé a largement progressé essentiellement grâce à l'amélioration génétique et aux performances accrues en matière de fertilisation et de protection de la culture. L'amélioration génétique a petit à petit transformé la plante de blé: l'accroissement du potentiel de rendement repose principalement sur l'amélioration des composantes du rendement déterminées tardivement: fertilité des épis et capacité de remplissage des grains. La part de matière sèche produite à partir du stade dernière feuille devient prépondérante. La fertilisation azotée de la culture s'adapte à cette évolution: report d'une partie de la fumure en cours de montaison (France), renforcement de la fraction de la fumure apportée au stade dernière feuille (Belgique). Le glissement d'une part de la fumure azotée vers des stades plus avancés de la culture modifie les données de l'interaction entre les maladies cryptogamiques et la fumure la pression des maladie diminue en début de montaison mais s'accentue en fin de végétation. Dès lors, les programmes de protection fongicides devraient privilégier la protection des organes supérieurs de la plante: dernière feuille et épi. Les nouveaux fongicides de la famille des strobilurines sont dans cette optique des outils très intéressants. [less ▲]

Presented in this paper are investigations on a possible side effect of repeated treatments with exogeneous gonadotropins in cattle, sheep and goats. First is given an historical approach of the discovery of human and equine chorionic gonadotropins including their biochemical properties. This review is continued with a brief report of some basic notions concerning the immune system followed by the description of respective sensitivities of different species to repeated gonadotropic treatments. A summarized presentation of the results of our investigations and those of different authors on circulating antibodies against exogeneous gonadotropins in the same species is then proposed. A synthetic reflexion leads to point out the positive influence of the philogenetic distance between the species - source of the gonadotropins (human or equine)- and the treated species -human, bovine, caprine, ovine- on the intensity of the immune reaction.
