Tornay, Serge. — Les Fusils Jaunes. Générations et politique en pays nyangatom (Éthiopie). Paris-Nanterre, Société d’ethnologie, 2001, 303 p.

Cet ouvrage représente la synthèse des recherches ethnographiques que l’auteur a conduites depuis 1970 dans la basse vallée de l’Omo en Éthiopie. En 1989, il soutenait, sous la direction du regretté Éric de Dampierre, une thèse d’État qui mettait en évidence le système social des Nyangatom comme un système générationnel : une première dans les recherches africanistes françaises. Les Fusils Jaunes ne sont pas le résumé de cette thèse, mais un essai mûri après plusieurs retours sur le terrain a..

Mechanochemical synthesis and characterization of nanodimensional iron–cobalt spinel oxides

Iron–cobalt spinel oxide nanoparticles, CoxFe3−xO4 (x = 1, 2), of sizes below 10 nm have been prepared by combining chemical precipitation with high-energy ball milling. For comparison, their analogues obtained by thermal synthesis have also been studied. The phase composition and structural properties of the obtained materials have been investigated by means of X-ray diffraction, Mössbauer spectroscopy, infrared spectroscopy, temperature-programmed reduction and magnetization measurements. X-ray diffraction shows that after 1 h of mechanical treatment ferrites are formed. The measurement techniques employed indicate that longer milling induces an increase in crystal size while crystal defects decrease with treatment time. Magnetization and reduction properties are affected by the particles size, the iron/cobalt ratio and the synthesis conditions

Familial and Clinical Correlates in Depressed Adolescents with Borderline Personality Disorder Traits

Introduction: Chart review is a low-cost, but highly informative, method to describe symptoms, treatment and risk factors associated with Borderline Personality Disorder (BPD) and to adapt screening and intervention to clinical reality. Previous chart review studies report more aggressiveness/anger and psychotic features in youths with BPD. They show that adverse family environment and parental psychopathology constitute important factors for BPD pathology. Objectives: To examine clinical characteristics of depressed BPD adolescents (12-17 years old) outpatients according to gender and to explore variables which are associated with BPD traits. Methods: A retrospective chart review using the Child and Adolescent Version of the Retrospective Diagnostic Instrument for Borderlines was conducted on 30 depressed BPD adolescents with BPD traits and 28 non-BPD depressed patients without BPD traits. Participants who reached the C-DIB threshold for BPD were included in the BPD traits group. The Child and Adolescent Version of the Retrospective Diagnostic Interview for Borderlines was used to determine the presence of BPD. Comparisons analyses were performed using Pearson’s Chi-square test. Associated factors were determined using regression analyses. Results: BPD traits participants outpatients were characterised by higher family problems (parental psychopathology, parent disagreement/argument, parent-child relational problem), more aggressive symptoms, and higher rates of family intervention and hospitalisation. A number of familial factors (parental history of delinquency, substance use, or personality disorders, having siblings, parental disagreement/argument in boys) were associated with BPD symptomatologytraits. Attention seeking and problematic functioning (does not adapt well to group activities) were also associated with BPD traits. Discussion: Our study stresses the need to assess BPD traits in adolescent psychiatric evaluation, especially in presence of aggressive behaviours, family problems and attention seeking. Our results also highlight the importance of exploring family characteristics intervention in adolescents with BPD traits

Safety assessment of the process DY Polymer, based on PET direct iV+ technology, used to recycle post-consumer PET into food contact materials

[EN] The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP) assessed the safety of the recycling process DY Polymer (EU register number RECYC197), which uses the Starlinger PET direct iV+ technology. The input is hot caustic washed and dried poly(ethylene terephthalate) (PET) flakes mainly originating from collected post-consumer PET containers, with no more than 5% PET from non-food consumer applications. The flakes are extruded to pellets, which are then crystallised, preheated and treated in a solid-state polycondensation (SSP) reactor. Having examined the challenge test provided, the Panel concluded that the three steps, extrusion, crystallisation and SSP, are critical in determining the decontamination efficiency of the process. The operating parameters to control the performance of these critical steps are temperature, gas flow, pressure and residence time. The challenge test demonstrated that this recycling process is able to ensure that the level of migration of potential unknown contaminants into food is below the conservatively modelled migration of 0.1 ¿g/kg food. Therefore, the Panel concluded that the recycled PET obtained from this process is not of safety concern, when used at up to 100% for the manufacture of materials and articles for contact with all types of foodstuffs for long-term storage at room temperature, with or without hotfill. The final articles made of this recycled PET are not intended to be used in microwave and conventional ovens and such uses are not covered by this evaluation.Lambré, C.; Barat Baviera, JM.; Bolognesi, C.; Chesson, A.; Cocconcelli, PS.; Crebelli, R.; Gott, DM....

Safety assessment of the process Marmara PET Levha, based on Starlinger deCON technology, used to recycle post-consumer PET into food contact materials

[EN] The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP) assessed the safety of the recycling process Marmara PET Levha (EU register number RECYC222), which uses the Starlinger deCON technology. The input material is hot washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post-consumer PET containers, e.g. bottles, including no more than 5% PET from non-food consumer applications. The flakes are preheated before being submitted to solid-state polycondensation (SSP) in a continuous reactor at high temperature under vacuum and. Having examined the challenge test provided, the Panel concluded that the preheating (step 2) and the decontamination in the SSP reactor (step 3) are critical in determining the decontamination efficiency of the process. The operating parameters to control the performance of these critical steps are temperature, pressure, residence time and. It was demonstrated that this recycling process is able to ensure a level of migration of potential unknown contaminants into food below the conservatively modelled migration of 0.1 lg/kg food. Therefore, the Panel concluded that the recycled PET obtained from this process is not considered to be of safety concern, when used at up to 100% for the manufacture of materials and articles for contact with all types of foodstuffs for long-term storage at room temperature, with or without hotfill. The final articles made of this recycled PET are not intended to be used in microwave or conventional ovens and such uses are not covered by this evaluation. (C) 2021 European Food Safety Authority.
