La Note du Traducteur comme Manifestation de la Dissonance Cognitive

La "note du traducteur" comme un cas d'ajout cognitif se manifeste comme une technique de traduction, dont le recours est motivé par la recherche d'un état consonant, à la suite d'une situation de dissonance cognitive engendrée par le désaccord avec l'auteur source, et ce par l'adoption du mécanisme nommé "ajout de cognition". Ainsi, l’analyse à la lumière de la théorie psychosociologique de la dissonance cognitive, et le recours aux "notes de traduction" dans un texte historique, met en exergue le désaccord présent entre les sens du texte source et la pensée du traducteur. Une telle approche permettrait d'éclairer une partie du processus psychologique (cognitif) chez le traducteur, à travers ces espaces qu’il utilise pour marquer sa présence intellectuelle

Chemical, mechanical and thermal properties of mortar composites containing waste PET

International audienceThe main objective of this study was to investigate the potential utilization of polyethylene terephthalate PET waste incementitious matrix, as substituent to cement, to develop lightweight construction materials and for preventing chemical attacksor repairing various reinforced concrete structures. Composites containing different amounts of PET particles, as partialreplacement to cement by weight, were characterized by destructive and non-destructive testing. So, the thermal conductivity,ultrasonic pulse velocity (UPV) and sorptivity coefficients of composite made up of mixtures of PET polymer were measured;the adverse environmental conditions are simulated by using various acid solutions. The corrosion process was monitored bymeasuring the mass loss and compressive strength for different periods. The experimental investigation revealed that the additionof PET particles reduces the UPV; furthermore, thermal conductivity and sorptivity of the composites have been decreased. So,the decrease of the sorptivity-value is favorable to the durability of the specimen structures. On behalf of the resistance toaggressive environments, it was found that the course of action of acid attack is dependent on the type of acid and solubility ofthe calcium salt formed. The presence of PET was found to lower the detrimental effect of acids on composite. Scanning electronmicroscope (SEM), X-ray diffraction and FT-IR analyses were used to better understand the cement hydration products of thedeteriorated mortars. In this way, the obtained PET-mortar composites would appear to be low-cost materials which wouldcontribute to resolving some of the solid waste problems in addition to conserving energy

Water Sap flow and Soil Moisture Measurements for an Automatic Irrigation Control System

A sound water management requires accurate field data inquiry that can eventually allow for a proper control of the field’s irrigation. This work pro-poses an automatic irrigation control system that aims at optimizing the quantity of water needed for plants’ growth. The system consists of three key blocks: first, the continuous inquiry of the physical characteristics of the plant; second, the control unit to decide upon the actions to launch by the actuation unit; and third the actuation unit that sets parameters for pumps and valves. Conventional smart irrigation control systems use soil moister sensors which neglect the plant’s physiology as a monitoring factor, so this paper suggests the use of a sap flow sensor that accurately evaluates the plant’s condition; hence, decide upon the proper water distribution, illustrated with preliminary experimental results
