Le but de cette communication est d’introduire un modèle clinique de diagnostic de situations de souffrance relationnelles au travail, y compris le harcèlement moral. Ce modèle vise à offrir aux professionnels une grille d’analyse utilisable dans le cadre d’entretiens avec des personnes se sentant victimes de harcèlement moral ou de violence au travail. Les corpus théoriques de référence sont principalement la littérature clinique et organisationnelle sur le harcèlement moral, celle sur la violence au travail, l’analyse systémique des phénomènes d’abus et de conflit en organisation et le coping en situation de stress. Ce modèle a été construit à partir d’un programme de recherche-action comprenant d’une part la rencontre de personnes s’estimant victimes de harcèlement moral, et d’autre part l'analyse d’interventions en organisations à des fins de gestion de conflits. Une méthode d’analyse de cas a été appliquée afin d’identifier dans les témoignages de victimes quels étaient les éléments déterminants d’une situation de harcèlement moral. Plus précisément, nous avons inventorié pour chacun des entretiens les comportements de harcèlement décrits par les personnes, les conséquences qu’elles rapportaient, leurs stratégies pour y faire face, la durée et le contexte organisationnel de la situation. Les interventions en organisations ont été également analysées afin d’investiguer la manière dont les personnes définissaient et décrivaient les situations de souffrance relationnelles au travail. Dans ce cas, c’est l’ensemble des protagonistes que nous avons interrogés sur les sujets étudiés dans les analyses de cas. Ce modèle propose de distinguer cinq phénomènes : la souffrance aiguë au travail, la violence au travail, l’hyperconflit au travail, l’abus sur le lieu de travail et le harcèlement moral. Afin de mener le diagnostic, des critères discriminants sont proposés : l’observation des conséquences sur le bien-être, l’analyse des comportements hostiles, l’observation des dynamiques cognitives entre les parties, la complémentarité de la relation et l’échec du coping.

This paper shows the identification of material parameters for a DC06 IF steel sheet of 0.8 mm by mechanical tests. The experimental equipment used consists of a tensile test machine, a bi-axial test machine able to perform plane-strain and simple shear tests separately or simultaneously and an optical strain gauge. Tensile, plane-strain and simple shear tests were performed at 0°, 45° and 90° from the sheet rolling direction in order to identify Hill 1948 and Hosford 1979 yield criteria. Two identification methods are used: one based on strain measurements (anistropy coefficients) and the other one based on stress measurements (plastic contours). The results confirm that mechanical tests applying other stress-states than tensile are required to obtain accurate material parameters identification. [less ▲]

Single-point incremental forming (SPIF) is a sheet metal forming technique that has gained particular interest in rapid prototyping and small volume production. The study of the underlying forming mechanisms is supported by new developments in finite element simulations and experimental full field strain measurements. This article aims to describe the possibilities and difficulties encountered during validation of finite element predictions of the incremental forming process. The drawing of a straight line into a metal plate was selected as a first test case for this kind of validation. Results of both finite element simulation and experimental work will be discussed.

This paper describes the outcome of the work performed during the 28th Alpbach Summer School, focused on the theme The Birth, Life and Death of Stars. We propose a mission consisting of a large aperture (3.5m main mirror diameter) UV space telescope, with capabilities for imaging and low, medium and high resolution spectroscopy. Even though such a telescope can have multiple scientific applications, we suggest a survey-type mission (SUGAR-1), dedicated mainly to the spectroscopic study of starburst galaxies at redshift z ~ 1, which corresponds to an epoch of enhanced star formation density in the history of the Universe and, in particular, to the time when our Solar System was born. Stars are the fundamental building blocks of galaxies. A major aspect of understanding galaxy formation and evolution is to understand their star formation history. Starburst galaxies are galaxies experiencing intense star forming activity and exhibiting strong UV emission from a young, hot stellar population. The study of starbursts helps us to understand the star formation process, and its influence on the environment and processes in the interstellar gas. The study of the star formation rate (SFR) at various redshifts is possible from the intensities of the H, H, OII and OIII lines, and the luminosity of the UV continuum. These can be used to generate Madau plots, which are diagnostic. Madau plots indicate that a peak of star formation in the history of the Universe occurred at z ~ 1, which corresponds to -5 Gyr, i.e. the moment of the birth of our own Solar System. Observations of this era will enable us to investigate the initial conditions in galaxies like ours when the formation was triggered. By observing a large number of galaxies at 0.4 < z < 1.1, we can learn about the properties of the star formation processes and the conditions of the interstellar medium (ISM) and its chemical properties at this moment of enhanced star formation. Spectroscopy and imaging in the UV will have a great impact on galaxy evolution modeling, since they will provide insight on whether the time corresponding to z = 1 was a time of massive galaxy formation, or if the massive star formation of that time took place in already established galaxies, which were formed at a much earlier stage in the evolution of the Universe. Moreover, studies of the Universe at z ~ 1 are of cosmological relevance, because according to the Cosmological Standard Model, it is precisely at z ~ 1 when the Universe underwent a phase transition from ΩMatter being larger than ΩDarkEnergy, to the opposite. Therefore, to investigate this interesting time in the evolution of the Universe, we suggest the construction of a dedicated UV telescope with a pre-defined science mission to perform Spectrometry in Ultraviolet GAlaxies at Redshift-1 (SUGAR-1). In what follows, a more detailed description of the mission science goals is given. We will show how the science goals are transformed into science requirements for the mission, which are turned into telescope and instrument requirements. Then a brief description will be given of the main technical aspects of the mission (spacecraft structure, electronics, power and orbit). The spacecraft mass and cost budgets of the mission are addressed, ending with a final summary. [less ▲]

The forging process of cylinders requires the knowledge of material recrystallisation conditions to prevent crack appearance. Due to the continuous recrystallisation during forging, very large deformations can be applied as the generated dislocations do not yield to hardening but to recrystallisation phenomenon.

Lower respiratory troubles in mature sports horses mainly include viral diseases (influenza, rhinopneumonia) ; bacterial diseases (that are generally due to commensal bacteria invading the lower respiratory tract because of an impairment of the pulmonaty defences); inflammatory processes (mainly in horses suffering from heaves and inflammatory airway disease) and exercise-induced pulmonary haemorrhages. Dysfunction such as hypersecretion of mucus, bronchospasms, bronchial hypereactivity and oedema may complicate any of this diseases. Treatments focusing on the etiological agents (anti-viral therapy, modulation of immunity, and antibiotic therapy), on the associated symptoms (anti-inflammatory, bronchodilators, regulator of the muco-ciliary clearance) and on the nursing and general management (rest and environmental hygiene) are described in this review [less ▲]

We previously showed that low levels of day-14 CD3 T and NK (CD56) cells donor chimerism predicted graft rejection, whereas high levels of day-28 CD3 T-cell donor chimerism predicted acute graft-versus-host disease (GVHD) after HCT with nonmyeloablative conditioning. Here we investigate whether assessing chimerism levels among CD4 T cells and CD8 T cells, and also the absolute number of lymphocyte subsets of donor and host origins, would lend greater precision to our initial observations. We analyzed data from 157 patients receiving HCT after conditioning with 2 Gy TBI +/− fludarabine as treatment for AML (n= 22), ALL (n= 4), CML (n= 13), CLL (n= 19), MDS (n= 26), MM (n= 24), NHL (n= 30), HD (n= 14), RCC (n= 4), and WASP deficiency (n= 1). Postgrafting immunosuppression included MMF and CSP. A total of 97 patients received grafts from HLA-identical siblings, and 60 patients received grafts from HLA-matched unrelated donors. Lymphocyte subsets were isolated from peripheral blood by flow cytometry on days 14, 28, and 42. The proportion of cells of donor origin (chimerism levels) were assessed by VNTR-PCR and quantified by phosphor imaging. Eighteen patients (11%) had graft rejection. Day-14 donor chimerism levels< 50% among CD3 T (P =.0007), CD4 T (P =.03), and NK cells (P =.003) but not CD8 T cells predicted graft rejection. High absolute numbers of CD3 T (P =.002) and NK cells (P= .002) of host origin on day 14 were each associated with increased risks of graft rejection when treated as continuous linear variables. Grades 2, 3, and 4 acute GVHD were seen in 40%, 9%, and 5% of patients, respectively. High donor chimerism levels on day 14 among CD3 T (P= .02), CD4 T (P =.03), and CD8 T cells (P =.02) but not NK cells were each associated with increased risks of grades 2–4 acute GVHD. High absolute numbers of CD4 T (P =.04) and CD8 T cells (P =.04) of donor origin on days 14–42 were each associated with increased risks of grade 2–4 acute GVHD when treated as continuous linear variables, whereas high donor CD3 T (P= .002), CD8 T (P= .006), and NK cell (P= .002) chimerism levels from days 14–42 were associated with decreased risks of relapse. No statistically significant correlations between absolute numbers of donor cells and risks of relapse were found. These data suggest that assessing CD3, CD4, CD8, and NK cell donor chimerism levels and determining absolute numbers of CD3 and NK cells of host and donor origins are useful for predicting HCT outcomes after nonmyeloablative conditioning.

In the present study, deep drawing simulations were investigated using a recently developed mixed type finite element (FE): the BWD3D. The main formulation of the element is described, with particular focus on the shear locking treatment. Two hardening models used in the presented simulations are described: the isotropic Swift’s model and the physically based microstructural Teodosiu and Hu model. Finally, deep drawing results, in terms of earing profile, are compared to experiment. Special attention is paid to the effects of texture evolution and hardening models; the method used to implement Teodosiu and Hu hardening model is also discussed. [less ▲]

Due to their low geometric probability, planetary transits are rare, and photometric surveys searching for such events have to observe many stars at once and, thus, deal with rather crowded fields. This crowding has two negative effects on the final results of the survey: it decreases the number of detectable transits and increases the number of false positives. We have studied the influence of crowding on different surveys (existing ones as well as planned or even fictitious ones). On the basis of simple but realistic assumptions about the fraction of lower main sequence stars harboring telluric and giant planets within the outer limit of their habitable zone, we predict the harvests of several surveys with and without taking into account the losses due to blends. Our results show that deep surveys such as OGLE-III are much more affected by blends than wide field surveys. Space missions such as Corot and Kepler, although they use very broad PSFs in order to increase the S/N, loose a much lower fraction of transits than deep ground-based surveys. We have also estimated the proportion of false positives in the harvest of the surveys. Thus, our results provide a reliable comparison between the considered surveys. [less ▲]

In the North of Belgium the Boom Clay Formation, at a depth of 200m below surface, is being evaluated as a potential host formation for the disposal of vitrified nuclear waste. The aim of this study is to model the transport of radionuclides through the clay, taking into account the geological heterogeneity and the excavation induced fractures around the galleries in which the waste will be stored. This is achieved by combining a transport model with geostatistical techniques used to simulate the geological heterogeneity and fractures of the host rock formation. In a first phase, 100 simulations of the hydraulic conductivity of the clay are generated by conditional stochastic simulation, using measurements of hydraulic conductivity and 4 types of secondary variables: resistivity logs, gamma ray logs, grain size measurements and descriptions of the lithology. Thereafter, 100 simulations of the fractures around the excavation are generated based on information about the extent, orientation, spacing and aperture of excavation induced fractures, measured around similar galleries. Subsequently, the hydraulic conductivity simulations and the fracture simulations are randomly combined and used as input for a transport model that calculates the transport by advection, diffusion, dispersion, adsorption and decay through the heterogeneous and fractured medium. The effect of “self healing” of the clay formation as a function of time after excavation is taken into account. Finally, this results in 100 breakthrough curves of radionuclides in the aquifers surrounding the Boom Clay, reflecting the uncertainty of travel time through the clay resulting from the uncertainty of the hydraulic conductivity and the fracture distribution. The breakthrough curves can serve as a risk management tool in the evaluation of the suitability of the Boom Clay Formation as a host rock for vitrified nuclear waste storage. [less ▲]

We present a new 3D full-frame profilometer based on structured laser light projection method. This device takes advantage of the polarization states splitting technique for producing and shifting multiple sinusoidal Young’s interference patterns that are projected on the inspected surface. The principle of the technique is presented and we discuss the advantages of monochromatic light projection method as a mean to overcome ambient lighting for in-situ measurement. Some results that we obtained on objects from the Egyptian Department of the British Museum are presented to demonstrate that 3D laser profilometry is a worthwhile technique for epigraphic investigations where naked-eye inspections fail.

The lithic assemblages of Siuren I (Ukraine) suggest that two successive phases can be distinguished in the Krems-Dufour facies of the Aurignacian in Eastern Europe (Demidenko et al.). The assemblages of Kostenki 1 (Russia) and Mitoc-Malu Galben (Romania) do not contradict this distinction and show the functionnal role of the sites in the representation of lamellar products.

The bi-axial experimental equipment [1] developed by Flores enables to perform Baushinger shear tests and successive or simultaneous simple shear tests and plane-strain tests. Such experiments and classical tensile tests investigate the material behavior in order to identify the yield locus and the hardening models. With tests performed on two steel grades, the methods applied to identify classical yield surfaces such as Hill or Hosford ones as well as isotropic Swift type hardening or kinematic Armstrong–Frederick hardening models are explained. Comparison with the Taylor-Bishop-Hill yield locus is also provided. The effect of both yield locus and hardening model choice will be presented for two applications: Single Point Incremental Forming (SPIF) and a cup deep drawing. [less ▲]
