This paper fits in a broader research project funded by the Belgian F.R.S.-Fonds national de la Recherche scientifique. It is entitled: Africa in the “science policies” of France and Great Britain from the eighteenth to the mid- nineteenth century: the scholarly background of the Scramble. This general project aims at completing in an original way recent studies on the interactions between the “New Science” derived from the Scientific Revolution and the building of colonial empires in the Atlantic area from the Enlightenment to the apogee of the first Industrial Revolution. Its objective is to investigate how in this period Africa has become a scientific object in its own right for the colonial administrations of France and Great Britain. Botanical knowledge (industrial plants, food crops and medicinal herbs) that originated in Africa was first applied in the plantations of slave economies in the Caribbean and North America. It was increased with knowledge about the geography and natural history of the continent’s interior through a revival of exploration in Africa itself. The project aims to relate the increased interest from scholars for Africa to the intensification of economic and military competition between the powers. It also wants to demonstrate how a more precise knowledge of the African terrain influenced the ways in which the governments of both countries have integrated colonial expertise in a complex science policy adapted to the specific needs of the two states. In this paper I will focus on the British side of the spectrum. I will investigate the changing British attitude towards Africa in the early nineteenth century through a case study of an expedition to the River Congo organized in 1816. Although this expedition ended in disaster (a majority of the members died in the course of the undertaking), it offers a series of useful examples that help to illustrate the transformation of British science policies under the pressure of competition with the French. Thus, it is my aim to show how Great Britain in the face of state-oriented French science has abandoned its policy of informal relationships and started to encourage its administration and scientific institutions to intervene more directly in exploration. Crucial in this evolution was the way in which the Admiralty absorbed the scholarly input of a number of learned societies and institutions, such as the Royal Society, the British Museum or the so-called “African Association” – the latter combining both scientific and commercial objectives. Thus the expedition illustrates the transition from Late Enlightenment “Banksian” exploration, inspired by the omnipotent science organizer Sir Joseph Banks (1743-1820), towards a more thorough imperial design of exploration under the command of Sir John Barrow (1764-1848). Already since the French conquest of Egypt, “scientific” expeditions relied on the collaboration between learned networks and the military, an example that would be copied later in Algeria. At the British side, it was the Admiralty that strengthened its grip on exploration. Tuckey’s expedition illustrates very well the amplification of operations, the more direct intervention by the government, and the growing importance of the commercial agendas of science. I will focus here on the interaction between the Admiralty and the learned societies with regard to the composition of the instruction text given to the leader of the expedition on the eve of his departure, on the specific choice of the area he had to explore (related to the “Niger question”), on the practical organization (e.g. the development of special steam engines by the engineer Watt, the scientific equipment offered with the help of the British Museum, etc.), on the choice of the scientists who formed a real team of experts (e.g. Christen Smith, John Cranch, etc.), on the collection of scientific data and their integration in collections in Britain, on the presentation of the expedition’s results in a published report entitled Narrative of an expedition to explore the river Zaire, usually called the Congo, in South Africa, in 1816, under the direction of Captain J. K. Tuckey, R.N., (London, 1818), and finally, on the circulation of these results in the rest of Europe due to the translation of the report in Dutch and French. [less ▲]

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.
