BACKGROUND. Depression is a psychopathology that affects many people (33.4 million every year in Europe). Depressed patients may demonstrate large variations in the evaluation of themselves (instability of self-esteem and of self-efficacy). In addition, it has been demonstrated that, in the general population, negative feelings and emotions are positively correlated with the volatility of self-representations. However, no study has assessed the stability of personal identity in depressed patients. Some researchers have nevertheless shown that changes in personality traits are observable in the development of depressive disorder. HYPTHESES. Depressed patients’ description of their traits of personality varies depending on the mood phases crossings unlike that of control subjects who remained stable. METHOD. Depressed patients (N = 17, M age = 51) were compared to control subjects (N = 18, M age = 47). Severity of depressive symptoms (BDI -II), implicit (name - letter task) and explicit (CSR) self-esteem, stability of identity and self-concept clarity were assessed. RESULTS. Depressed patients have a self-perception less stable than control subjects and a lower clarity of identity. The severity of depressive symptoms was positively correlated with poorer clarity of identity. DISCUSSION. These results support our hypothesis. Experimental and clinical perspectives of these will be discussed. [less ▲]

Introduction : Des interventions non pharmacologiques peuvent réduire le risque que des aidants professionnels qui accompagnent des personnes âgées (atteintes ou non de démence) développent des attitudes âgistes[1], un sentiment d’incompétence[2], une insatisfaction professionnelle[3,4] et un burnout[2]. Ces interventions sont néanmoins essentiellement destinées aux aidants en milieu institutionnel. Objectif : Évaluer, au niveau de différents paramètres (âgisme, connaissances sur la maladie d’Alzheimer, sentiment de compétence, satisfaction professionnelle, burnout, stratégies de coping), l’efficacité d’une formation destinée à des aidants professionnels à domicile. Méthodologie : 18 aides familiales ont bénéficié d’une formation de trois jours visant à améliorer leurs connaissances sur les démences et à les aider à mettre en place des stratégies de résolution de problèmes face aux difficultés rencontrées dans leur pratique, et ceci, afin de favoriser une vision moins stigmatisante de la maladie d’Alzheimer. Différents auto-questionnaires ont été complétés par les participantes avant et après l’intervention. Résultats : Les analyses statistiques indiquent que la formation permet de diminuer l’âgisme des aidantes, d’améliorer leurs connaissances sur la maladie d’Alzheimer et leur satisfaction vis-à-vis de leurs tâches professionnelles. Les stratégies de coping centrée sur la résolution de problème sont également considérées comme plus aidantes. Conclusion : L’intervention est efficace puisqu’elle atteint ses objectifs initiaux. Ces résultats encouragent non seulement la formation des aidants professionnels à domicile mais aussi l’évaluation de l’efficacité des interventions proposées, à la fois auprès des aidants professionnels, informels et des personnes accompagnées. En effet, sur base de la littérature[5,6], nous faisons l’hypothèse que l’amélioration des connaissances et la diminution de l’âgisme réduisent le risque d’induire des comportements de dépendance chez les personnes accompagnées. Ce constat est important compte tenu du rôle des aides familiales, à savoir aider les personnes âgées (atteintes ou non de démence) qui présentent des difficultés dans la réalisation des activités (instrumentales) de la vie quotidienne afin qu’elles restent le plus longtemps possible à leur domicile.

Cement will remain the key material to satisfy global housing and modern infrastructure needs. Cement production has undergone a tremendous development from its beginnings some 2000 years ago. Today's annual global cement production has reached 3.6 billion tones, and is expected to increase to some 4 billion tones per year. Major growth is foreseen in countries such as China and India as well as in regions like the Middle East and Northern Africa. Cementitious materials, such as cement pastes and mortars, are the object of a massive use in the buildings, in engineering works or in public roads. their good mechanical resistance properties, justifies having a resort. Another aspect is also taken into account, their durability. From macroscopic aspects transfer coefficients have a direct influence on the mechanical behavior and the durability of the structure, bound to the drying of cementitious materials. In the process of drying many problems are encountered such high energy consumption, kinetic of drying and the final shape of the product. In fact, the improvement of drying system is becoming a necessity. This paper considers the convective drying of an unsaturated wet mortar slab. A calculation model is given, which use the equations of the drying air and those describing the transfer of heat and mass in the porous media. The diffusion model is used to simulate the internal heat and mass transfers. Equations of the drying air (continuity, momentum, energy and mass equations) are written, using the classical assumptions in the boundary layer. The results allow analyzing the drying process, by deducing the space and temporal evolution of the heat and moisture distribution in the porous slab and in the drying air. The evolutions of local heat and mass transfer coefficients on the slab surface are also deduced and analyzed [less ▲]

The objective of this study was to discriminate by a NIR line scan hyperspectral imaging, taxonomic plant families comprised of different grassland species. Plants were collected from semi-natural meadows of the National Apuseni Park, Apuseni Mountains, Gârda area (Romania) according to botanical families. Chemometric tools such as PLS-DA were used to discriminate distinct grassland species, and assign the different species to botanical families. Species within the Poacea family and Other Botanical Families could be distinguished (R2=0.91 and 0.90, respectively) with greater accuracy than those species in the Fabacea family (R2=0.60). A correct classification rate of 99% was obtained in the assignment of the various species to the proper family. Moreover a complete study based on wavelength selection has been performed in order to identify the chemical compound related to each botanical family and therefore to the possible toxicity of the plant. This work could be considered as a first step for the development of a complete procedure for the detection and quantification of possible toxic species in semi-natural meadows used by grazing animals.
