Les fluides de coupes : état des connaissances sur les usages, les expositions et les pratiques de gestion en France : rapport d'étude

Les fluides de coupe sont principalement utilisés pour leurs propriétés lubrifiantes et/ou pour leur qualité de refroidissement des pièces en métallurgie. Ils sont utilisés pour faciliter l'opération d'usinage et contribue à améliorer la durée de vie de l'outil utilisé. Ils permettent d'éloigner les copeaux de la zone de coupe, ce qui contribue à l'obtention d'un état de surface de qualité, et de refroidir le copeau et la pièce usinée afin de contribuer à la précision dimensionnelle de la pièce finie. Les usages des fluides de coupe sont en évolution depuis les années 2000. Il y a environ 15-30 ans, seules les huiles entières étaient utilisées. Aujourd'hui, l'utilisation des huiles varie selon le type d'application mais il est à noter toutefois que l'usage des huiles entières est en pleine décroissance depuis 2001, contrairement à celui des fluides aqueux (émulsions) en pleine expansion. Les fluides de coupe exposeraient selon l'étude SUMER plus de 1 million de travailleurs. Il existe deux grands secteurs principaux utilisateurs de ces fluides : le travail des métaux (qui expose selon l'INRS le plus grand nombre de salariés) et l'automobile (plus grand secteur utilisateur selon la CSNIL, Chambre Syndical Nationale de l'Industrie des Lubrifiants). De nombreux éléments existent autour de la prévention des risques liés à l'utilisation des fluides de coupe mais comme le rappelait l'INRS dans son rapport publié en 2002, la plupart des méthodes de prévention, collectives ou individuelles, bien que déjà connues, ne sont pas toujours appliquées, et notamment dans les petites entreprises. De plus les moyens de surveillance, bien que largement détaillés dans de nombreux guides, sont rarement mis en oeuvre. Néanmoins, des substances dangereuses peuvent se retrouver soit au sein de la formulation des fluides de coupe (comme certains additifs, biocides..), soit se former au cours du stockage (comme c'est le cas de pour la NDELA, N-nitroso diéthanolamine). Certaines substances ont déjà vu leur usage en tant que biocide être interdit en France, tel que le formaldéhyde ou encore l'acide borique. Des solutions de substitution existent déjà, telles que la micro-lubrification ou l'usinage à sec. Mais la mise en place ou la recherche de substituts s'accompagne souvent de difficultés en ce qui concerne l'adaptation du processus industriel. La mise en oeuvre des collaborations avec les fournisseurs doit donc être fortement encouragée. Enfin, il existe des zones d'ombre concernant les risques associés au développement microbiologique intervenant lors du vieillissement des fluides. L'utilisation grandissante de ces fluides de type aqueux est en lien avec ces problèmes de contamination microbienne des fluides ainsi que les pathologies respiratoires qui semblent y être associées. Cependant l'absence de référentiel exclut toute interprétation des résultats relatifs à ces agents microbiologiques retrouvés à la fois dans les fluides et les aérosols. Conclusions : En raison de la complexité de la formulation des fluides de coupe, il n'existe pas aujourd'hui de méthode de mesure fiable pour évaluer l'exposition à ces produits. Ainsi la mise en place d'une évaluation quantitative des risques sanitaires complète semble prématurée voire impossible. Il apparaît cependant nécessaire d'aller plus loin en matière de prévention : - une valeur limite pourrait être imposée concernant les quantités en amines secondaires précurseurs de nitrosamines, telle que développée dans le modèle allemand, le respect de cette réglementation allemande est déjà un argument mis en place par certains fournisseurs français ; - La micro-lubrification et la recherche de substitution doivent être encouragées ; - L'élaboration d'un référentiel microbiologique qui puisse tenir compte de la qualité des fluides et de la protection des travailleurs devrait être soutenue.

Color sensation in figurative painting

The figurative painter accesses very complex levels of knowledge. To produce a painting requires, first, a deep analysis of the image of the reality and, afterwards, the study of the reconstruction of this reality. This is not about a process of copying, but a process of the comprehension of the concepts that appear in the representation. The drawing guides us in the process of the production of the surface and in the distribution of the colours that, after all, are the data with which the vision mechanism builds the visual reality. Knowing the colour and its behaviour have always been a requirement for the figurative painter. From that knowledge we can draw wider conclusions.

La "bientraitance", exploration du concept et essai d'utilisation en santé publique: une expérience à Fribourg (Suisse). ["Bientraitance": conceptual exploration and an example of its application in public health: an experience from Fribourg, Switzerland]

Since the year 2000, the concept of "bientraitance" (for which no equivalent term has yet emerged in either the English or German language) has gained widespread credence among educators, sociologists and health professionals in France and Belgium. This concept emphasizes a constructive approach to care and education rather than merely one of prevention of disasters. Applied in public health, and in particular to mental health promotion, the use of the concept of "bientraitance" can help promote both effectiveness and meaning in the design and planning of community interventions. The article presents an example of an intervention for children and adolescents in Fribourg, Switzerland. The underpinning hypothesis is that the children and youth groups (such as sports clubs, artistic and cultural associations, scouts and guides) represent largely untapped, or under-tapped, informal health resources with a favourable cost-effectiveness profile. "Bientraitance" criteria are used in selecting certain associations offering structured extracurricular group educational activities and collective out-of-school (or after school) programmes. Support is provided to the organisations selected for recruiting new members, in particular those with potentially lower levels of access, for example disabled children or new migrants. The results will be evaluated for the impact of participation in various out-of-school activities on health and health determinants from a prospective and comparative perspective. This paper shows how the concept of "bientraitance" can be useful in the development of a public health intervention.

Vers une gestion de la nature en termes d'action publique : analyse d'une dynamique d'appropriation des ressources végétales à Tobré, Nord Bénin

Cette étude se fonde sur des recherches ethnographiques menées autour de la mise en oeuvre d'une politique publique de gestion de la nature à Tobré, une région baatonu au Bénin. L'étude se place dans une dynamique d'appropriation des ressources naturelles en rapport avec l'entrée en jeu de multiples acteurs publics et privés dans l'arène locale de gestion de la nature. En effet, ces acteurs ont acquis ces dernières années de l'expérience et de l'efficacité à la faveur des changements institutionnels et politiques et s'incluent davantage dans le processus de décision au point de suppléer l'Etat dans les actions qui étaient ses prérogatives. L'étude met en lumière les rapports de conflits, de compétitions, de concurrence ou de compromis autour des enjeux sociaux, politiques et économiques de protection de la nature. Elle décrit et analyse les formes d'interactions entre les différents acteurs individuels, collectifs et institutionnels, afin de voir en quoi ces interactions participent du processus de mobilisation d'acteurs locaux et de confrontation de vision, qui finalement définit et oriente les politiques locales de protection de la nature. Pour atteindre cet objectif, l'étude mobilise des apports théoriques de plusieurs disciplines, notamment de la socio- anthropologie du développement, de l'histoire et de la sociologie politique. Elle repose également sur des données empiriques collectées à partir d'une combinaison d'outils techniques, des entretiens et des observations jusqu'au dépouillement de presse et des études de cas. Les principaux résultats montrent que les acteurs locaux, particulièrement les comités de gestion sont parvenus à inscrire la gestion des ressources naturelles dans l'espace public à travers les débats dans les médias, les forums, les marches de protestation, etc. De fait, ils ont été capables d'influer sur le processus de définition et de mise en oeuvre des politiques locales de protection de la nature et donc de reconfigurer l'arène locale de gestion des ressources naturelles. Ce qui amène l'Etat et ses services déconcentrés, en premier lieu les services des Eaux et Forêts et la mairie à pactiser avec ces différents comités, sans pour autant perdre de leur notoriété. Au contraire, ils participent de la gouvernance de l'ensemble des actions et permettent de mettre en place des formes de gestion négociée. - This is an ethnographic research on the implementation of a public policy for the management of natural resources in Tobre, a baatonu village in Benin. The study focuses on the dynamic of natural resources ownership in a context of multiple stakeholders in the public and private sectors. In recent years, these stakeholders have become more experienced and efficient as a result of several institutional and policy changes. The stakeholders are more involved in the decision making process to the point that they can complement the role of the State in natural resources management. This study highlights the conflicts, competition, or compromise associated with the social, political and economic constraints of nature conservation. The interactions between individual, collective and institutional stakeholders were analyzed, to understand their role in the process of mobilizing local stakeholders and confronting their visions. This process ultimately defines and guides local policies on the management of nature. To achieve this goal, this study combined theoretical approaches from developmental socio-anthropology, history and political sociology with empirical data collected using interviews, observations, newspapers analysis and case studies. The results show that local stakeholders, particularly the management committees, were successful at introducing the need for sustainable natural resource management in the mainstream public discourse through the media, forums, and demonstrations. They were able to influence the process of identifying and implementing local policies on nature conservancy. This has encouraged the State, through its forestry services, and the district mayors to collaborate with these committees in the shared governance of natural resources.

Geoepidemiology of autoimmune hemolytic anemia.

Autoantibodies against red blood cell antigens are considered the diagnostic hallmark of AIHA: Direct antiglobulin test (DAT) completed by cytofluorometry and specific diagnostic monoclonal antibodies (mAbs) allow for a better understanding of autoimmune hemolytic anemia (AIHA) triggers. Once B-cell tolerance checkpoints are bypassed, the patient loses self-tolerance, if the AIHA is not also caused by an possible variety of secondary pathogenic events such as viral, neoplastic and underlying autoimmune entities, such as SLE or post-transplantation drawbacks; treatment of underlying diseases in secondary AIHA guides ways to curative AIHA treatment. The acute phase of AIHA, often lethal in former times, if readily diagnosed, must be treated using plasma exchange, extracorporeal immunoadsorption and/or RBC transfusion with donor RBCs devoid of the auto-antibody target antigen. Genotyping blood groups (www.bloodgen.com) and narrowing down the blood type subspecificities with diagnostic mAbs help to define the triggering autoantigen and to select well compatible donor RBC concentrates, which thus escape recognition by the autoantibodies.

Total Cost of Transportation Analysis of Road and Highway Issues, HR-388, 2002

In the administration, planning, design, and maintenance of road systems, transportation professionals often need to choose between alternatives, justify decisions, evaluate tradeoffs, determine how much to spend, set priorities, assess how well the network meets traveler needs, and communicate the basis for their actions to others. A variety of technical guidelines, tools, and methods have been developed to help with these activities. Such work aids include design criteria guidelines, design exception analysis methods, needs studies, revenue allocation schemes, regional planning guides, designation of minimum standards, sufficiency ratings, management systems, point based systems to determine eligibility for paving, functional classification, and bridge ratings. While such tools play valuable roles, they also manifest a number of deficiencies and are poorly integrated. Design guides tell what solutions MAY be used, they aren't oriented towards helping find which one SHOULD be used. Design exception methods help justify deviation from design guide requirements but omit consideration of important factors. Resource distribution is too often based on dividing up what's available rather than helping determine how much should be spent. Point systems serve well as procedural tools but are employed primarily to justify decisions that have already been made. In addition, the tools aren't very scalable: a system level method of analysis seldom works at the project level and vice versa. In conjunction with the issues cited above, the operation and financing of the road and highway system is often the subject of criticisms that raise fundamental questions: What is the best way to determine how much money should be spent on a city or a county's road network? Is the size and quality of the rural road system appropriate? Is too much or too little money spent on road work? What parts of the system should be upgraded and in what sequence? Do truckers receive a hidden subsidy from other motorists? Do transportation professions evaluate road situations from too narrow of a perspective? In considering the issues and questions the author concluded that it would be of value if one could identify and develop a new method that would overcome the shortcomings of existing methods, be scalable, be capable of being understood by the general public, and utilize a broad viewpoint. After trying out a number of concepts, it appeared that a good approach would be to view the road network as a sub-component of a much larger system that also includes vehicles, people, goods-in-transit, and all the ancillary items needed to make the system function. Highway investment decisions could then be made on the basis of how they affect the total cost of operating the total system. A concept, named the "Total Cost of Transportation" method, was then developed and tested. The concept rests on four key principles: 1) that roads are but one sub-system of a much larger 'Road Based Transportation System', 2) that the size and activity level of the overall system are determined by market forces, 3) that the sum of everything expended, consumed, given up, or permanently reserved in building the system and generating the activity that results from the market forces represents the total cost of transportation, and 4) that the economic purpose of making road improvements is to minimize that total cost. To test the practical value of the theory, a special database and spreadsheet model of Iowa's county road network was developed. This involved creating a physical model to represent the size, characteristics, activity levels, and the rates at which the activities take place, developing a companion economic cost model, then using the two in tandem to explore a variety of issues. Ultimately, the theory and model proved capable of being used in full system, partial system, single segment, project, and general design guide levels of analysis. The method appeared to be capable of remedying many of the existing work method defects and to answer society's transportation questions from a new perspective.

General electromagnetic simulation tool to predict the microwave nonlinear response of planar, arbitrarily-shaped HTS structures

This work describes a simulation tool being developed at UPC to predict the microwave nonlinear behavior of planar superconducting structures with very few restrictions on the geometry of the planar layout. The software is intended to be applicable to most structures used in planar HTS circuits, including line, patch, and quasi-lumped microstrip resonators. The tool combines Method of Moments (MoM) algorithms for general electromagnetic simulation with Harmonic Balance algorithms to take into account the nonlinearities in the HTS material. The Method of Moments code is based on discretization of the Electric Field Integral Equation in Rao, Wilton and Glisson Basis Functions. The multilayer dyadic Green's function is used with Sommerfeld integral formulation. The Harmonic Balance algorithm has been adapted to this application where the nonlinearity is distributed and where compatibility with the MoM algorithm is required. Tests of the algorithm in TM010 disk resonators agree with closed-form equations for both the fundamental and third-order intermodulation currents. Simulations of hairpin resonators show good qualitative agreement with previously published results, but it is found that a finer meshing would be necessary to get correct quantitative results. Possible improvements are suggested.
