Jovian X-rays can be broadly classified into two categories: (1) "auroral" emission, which is confined to high-latitudes ( ˜>60° ) at both polar regions, and (2) "dayglow" emission, which originates from the sunlit low-latitude ( ˜<50° ) regions of the disk (hereafter called "disk" emissions). Recent X-ray observations of Jupiter by Chandra and XMM-Newton have shown that these two types of X-ray emission from Jupiter have different morphological, temporal, and spectral characteristics. In particular: 1) contrary to the auroral X-rays, which are concentrated in a spot in the north and in a band that runs half-way across the planet in the south, the low-latitude X-ray disk is almost uniform; 2) unlike the ˜40±20-min periodic oscillations seen in the auroral X-ray emissions, the disk emissions do not show any periodic oscillations; 3) the disk emission is harder and extends to higher energies than the auroral spectrum; and 4) the disk X-ray emission show time variability similar to that seen in solar X-rays. These differences and features imply that the processes producing X-rays are different at these two latitude regions on Jupiter. We will present the details of these and other features that suggest the differences between these two classes of X-ray emissions from Jupiter, and discuss the current scenario of the production mechanism of them.

This paper describes the main concepts of the stress-strain interpolation model that has been implemented in the non-linear finite element code Lagamine. This model consists in a local description of the yield locus based on the texture of the material through the full constraints Taylor’s model. The prediction of the Swift effect is investigated: the influence of the texture evolution is shown up. The LAMEL model is also investigated for the Swift effect prediction. [less ▲]

Observations of Jupiter carried out by the Chandra ACIS-S instrument over 24-26 February, 2003, show that the auroral X-ray spectrum consists of line emission consistent with high-charge states of precipitating ions, and not a continuum as might be expected from bremsstrahlung. The part of the spectrum due to oxygen peaks around 650 eV, which indicates a high fraction of fully-stripped oxygen in the precipitating ion flux. The OVIII emission lines at 653 eV and 774 eV, as well as the OVII emission lines at 561 eV and 666 eV, are clearly identified. There is also line emission at lower energies in the spectral region extending from 250 to 350 eV for which sulfur and carbon lines are possible candidates. The Jovian auroral spectra differ significantly from measured cometary X-ray spectra. The charge state distribution of the oxygen ion emission evident in the measured auroral spectra strongly suggests that, independent of the source of the energetic ions (magnetospheric or solar wind) the ions have undergone additional acceleration. For the magnetospheric case, acceleration to energies exceeding 10 MeV is apparently required. The ion acceleration also helps to explain the high intensities of the X-rays observed. The phase space densities of unaccelerated source populations of either solar wind or magnetospheric ions are orders of magnitude too small to explain the observed emissions. The Chandra X-ray observations were executed simultaneously with observations at ultraviolet wavelengths by the Hubble Space Telescope and at radio wavelengths by the Ulysses spacecraft. These additional data sets provide interesting hints as to the location of the source region and the acceleration characteristics of the generation mechanism. The combined observations suggest that the source of the X rays is magnetospheric in origin, and that strong field-aligned electric fields are present which simultaneously create both the several-MeV energetic ion population and the relativistic electrons believed to be responsible for the generation of 40 minute quasi-periodic radio outbursts.

L’objectif de ce travail est d’étudier, dans les conditions réelles de production, la variabilité de la qualité technologique, organoleptique et microbiologique de la viande de porc et d’objectiver les relations qui peuvent exister entre les variables évaluées. L’analyse en composantes principales a permis de mettre en évidence des groupes de variables et de visualiser les relations qui peuvent exister entre ces variables. La première composante principale est corrélée aux variables relatives à la qualité technologique et organoleptique de la viande. Elle met en opposition le pH45 d’une part et les paramètres L*, b* et Cond45 d’autre part. La deuxième composante principale peut être considérée comme un axe de qualité microbiologique. L’analyse en composantes principales a également permis de mettre en évidence des groupes d’individus.

This paper deals with the application of statistical process control techniques based on principal component analysis to vibration-based damage diagnosis of structures. Principal component analysis of the sensor time-responses allows to extract principal directions (i.e. features) which define a subspace that is representative of the dynamics of the instrumented structure. Any change in the response of a single sensor will affect the subspace spanned by the complete sensor response set. It follows that the subspace corresponding to the current state of the structure can be compared to the subspace of the initial state of the structure, assumed to be healthy, in order to diagnose possible damage. Principal component analysis may also be performed for every potential subset of damaged sensors in order to identify the involved sensor, and, therefore, the damaged substructure. In this paper, the problem of structural damage detection is addressed in the case of environmental vibration testing. A direct application is presented for a test item submitted to random vibration testing by means of an electro-dynamic shaker. [less ▲]

The prediction of the final axial stresses and the residual strains of complex extruded aluminium profiles requires a good knowledge of the material behavior and of the industrial process. This paper is focused on the methods required to provide the whole set of data: material ones and process ones. Scanning differential calorimetry, dilatometry and diffusivity tests identify thermophysic material properties and hot tensile tests identify parameters of the elastovisco- plastic Norton-Hoff law. The description of the industrial process and its simulations are described. Then a sensitivity analyzis provides the cooling key parameters causing the undesired final curvature during the industrial process. [less ▲]

Acetaldehyde, the first product of ethanol metabolism, has long been speculated to be involved in many of the behavioral effects of ethanol, although its precise role remains a matter of debate. However, most of the results supporting a role for acetaldehyde in ethanol’s effects come from studies in which ethanol metabolism was pharmacologically manipulated, whereas the behavioral properties of acetaldehyde itself are still largely unknown. In the present studies, we have characterized the locomotor, hypnotic, anxiolytic and amnesic effects of both ethanol and acetaldehyde in C57BL/6J and CD1 mice. Several classical behavioral tests were used: the open field, the loss of righting reflex, the plus-maze, the place conditioning and the passive avoidance. The results show that acetaldehyde similarly to ethanol induces sedation and hypnotic effects at high doses. In addition, acetaldehyde displays potent amnesic effects in the passive avoidance test, suggesting that the first metabolite of ethanol might be critically involved in the memory-impairing effects of ethanol. However, in contrast to ethanol, acetaldehyde does not show anxiolytic properties in the plus-maze. In a second part of the present studies, acetaldehyde contribution to ethanol’s behavioral effects was investigated by using several inhibitors of ethanol metabolism (3-amino-1,2,4-triazole, a catalase inhibitor, and disulfiram, an aldehyde dehydrogenase inhibitor). Overall, the present results suggest that acetaldehyde is involved in some of ethanol’s behavioral effects (amnesia, locomotor depression, sedation) but not in others (in particular anxiolysis).

Experimental testing equipment is built in order to identify material parameters of complex phenomenological constitutive laws. This equipment consists in a bi-axial test machine able to perform plane strain and simple shear tests separately or simultaneously and a Miyauchi simple shear test device; an optical extensometer is used to identify the strain field. The article focus on the validation of the results of this new equipment by comparing with results obtained by standard machines and/or by using FEM simulations of already identified materials. The first results show that the bi-axial machine performs the plane strain test optimally and some modifications are proposed in order to improve the results for the simple shear test. Miyauchi device shows a good performance and the experimental results are compared with a FEM simulation. [less ▲]

In this contribution we review the current status of the determination of the rotational frequency in non-radially pulsating B stars, i.e. beta Cep stars and slowly pulsating B stars. Considerable progress is currently being made in the understanding of the non-radial oscillations of main-sequence B Stars by means of high-temporal, high-spatial resolution spectroscopic time series. This has led to the detection of frequency multiplets, which are interpreted as rotationally splitted non-radial modes and which allow an accurate determination of the surface rotational frequency in some stars. We outline how our future goal, i.e. the derivation of the internal rotation frequency, can be achieved. [less ▲]

Following prescriptions of the recent European Water Framework Directive, a groundwater quality evaluation system must be adopted for checking the groundwater status with respect to different contaminants. A screening evaluation system (based on a system developed by the French Water Agencies) has been adapted to the specific conditions in the Walloon Region of Belgium. Groundwater quality data are aggregated into indicators with respect to different water uses such as drinking water standards, thresholds values for preserving dependent surface ecosystems, or the groundwater ‘natural or patrimonial state’. A global groundwater quality indicator can also be calculated. Different aggregation techniques are discussed with their respective influence on the final indicator. In relation to this evaluation, the monitoring network must be adapted for being (as far as possible) representative of the global quality of water in each groundwater body. Existing knowledge and understanding of the actual hydrogeological conditions were used in priority for choosing an adequate network of monitoring points. At the same time, the spatial density of points was checked in order to obtain a statistically representative network. Applications were performed in five different GWBodies belonging to the hydrographic district of the Meuse River in the Walloon Region and with different contrasted geological conditions: Cretaceous chalks, Carboniferous limestones and Pleistocene gravels of the alluvial plain of the River Meuse. These examples provide a good opportunity for further discussion and work about the main related issues: optimzation procedures, aggregation methods and estimation of the reliability of indicators.

This paper is dedicated to the identification of constitutive parameters of the Mohr-Coulomb constitutive model from in situ measurements. A general definition of an objective function is proposed. A direct approach of inverse analysis is used to identify the shear modulus and the friction angle in four different situations. The first two examples deal with a “numerical” and with a real pressuremeter curve. A difficult convergence and a strong non unicity of solution is observed, which is classical in inverse analysis (ill posed problems). In a second stage, the horizontal displacements related to two excavation problems are used for identifying the two mechanical parameters. A clear minimum of the objective function is detected, giving a unique solution. The reasons of these differences are discussed and some ways of improving the interpretation of the pressuremeter test results are proposed. [less ▲]

Major challenge for semi-solid processing includes broadening the range of alloys that can be successfully thixoformed and developing alloys specifically for thixoforming. One important parameter is appropriate solidus-liquidus interval. The wider the solidification interval, the wider the processing window. This study is related to the experimental determination of this critical parameter on eight different steel compositions. This parameter was obtained using Differential Scanning Calorimetry. This technique allows to obtain the solid fraction versus temperature. The paper also presents the results of thermophysical properties determination such as thermal diffusivity, heat capacity and thermal conductivity. These properties were measured from room temperature to semi-solid state in one particular steel. The thermal diffusivity was measured using the Laser Flash method and the heat capacity using a DSC calorimeter. The thermal conductivity was obtained by calculation knowing the thermal dilatation measured with a dilatometer. All these measurements were performed for temperatures up to the liquidus. These parameters are difficult to measure but they are important to determine for the conductive heating phase of a semi-solid forming (SSM) process. [less ▲]

Started since one decade now, Community forestry in Cameroon presents half-hearted results. The goals of the 1994 law which aims to improve participation of locals populations to forest management and to increase their incomes seems to be hard to reach. Still this management process is criticised, mostly because of the complexity of the “simple management plan”. This article presents and analyses different experimental steps that were tested since ten years in Badjoué land in East Cameroon in order to make changes this precious tool to a participative and sustainable management of natural resources.
