Le tournant fictionnel de la traduction au service de la visibilité du traducteur
No full textThis article deals with a case study belonging to what has been called the “fictional turn” in translation studies, that is the approach of fictional representations of translators or interpreters in literature and cinema. This perspective contributes to the visibility of translator and can shed new light on some theoretical issues about translation, especially when the author of the fiction is a practising translator
Coping with Iberian monopolies: Genoese trade networks and formal institutions in Spain and Portugal during the second half of the eighteenth century
No full textThis article explores Genoese trade interests in Cadiz and Lisbon, the two capitals of Iberian colonial trade at the end of the early-modern period. The author aims to explain the persisting intermediary role of a merchant community that has been largely overlooked by historians. The structure of the trade networks established in the two cities will be reconstructed by using the primary sources conserved in the archive of the Durazzos, a powerful aristocratic family of the Republic which has left a unique collection of private correspondence. This sizeable and largely unexplored documentation illuminates the different strategies used to access the Spanish and Portuguese monopolistic systems, the main actors who traded in both contexts, their relations with the local elite, and the nature of the business networks linking Genoese investors in the mother city with the expatriated agents. The author concludes with a comparative analysis of the institutional resources that Genoese used to maintain their interests, with particular attention paid to the religious institutions established by the 'nation' in the two port cities
Providing the motivation to prove in a dynamic geometry environment
No full textThe use of dynamic geometry software may provide opportunities to improve the teaching and learning of mathematical proof within the context of plane geometry. Yet, it seems, if the approach to proving continues to emphasise a standardised linear deductive presentation, little improvement in student conceptions may result. This paper considers the design of geometrical tasks that could provide the motivation to prove
The madeira touch: Encouraging visual-spatial exploration using a tactile interactive display
No full textThe current information marketplace for tourists is dominated by for-profit purveyors of information. Potential visitors must rely on experts-for-hire or search engine results in order to learn about a desired destination. In this paper, we introduce The Madeira Touch, a multimodal display installation rooted in the unique characteristics of Madeira, which allows users to explore the island by selecting a type of scenery and showing the user-generated photos of that type of scenery in a map-based interface. To make this pervasive display more engaging, we designed an exploratory tactile-input mode of interaction: users will be able to touch a physical object, representing a type of scenery (a rock for mountains, a seashell for the sea, etc.), which will then bring up suitable photos of that type of scenery overlaid on a map of the island. The display will help users to form their mental image of the island and to plan trips that best suit their interests. Copyright is held by the author/owner(s)

Supercapacitive microbial fuel cell: Characterization and analysis for improved charge storage/delivery performance
No full textAbstractSupercapacitive microbial fuel cells with various anode and cathode dimensions were investigated in order to determine the effect on cell capacitance and delivered power quality. The cathode size was shown to be the limiting component of the system in contrast to anode size. By doubling the cathode area, the peak power output was improved by roughly 120% for a 10ms pulse discharge and internal resistance of the cell was decreased by ∼47%. A model was constructed in order to predict the performance of a hypothetical cylindrical MFC design with larger relative cathode size. It was found that a small device based on conventional materials with a volume of approximately 21cm3 would be capable of delivering a peak power output of approximately 25mW at 70mA, corresponding to ∼1300Wm−3
Biomimetics in the design of a robotic exoskeleton for upper limb therapy
No full textCurrent methodologies in designing robotic exoskeletons for upper limb therapy simplify the complex requirements of the human anatomy. As a result, such devices tend to compromise safety and biocompatibility with the intended user. However, a new design methodology uses biological analogues as inspiration to address these technical issues. This approach follows that of biomimetics, a design principle that uses the extraction and transfer of useful information from natural morphologies and processes to solve technical design issues. In this study, a biomimetic approach in the design of a 5-degree-of-freedom robotic exoskeleton for upper limb therapy was performed. A review of biomimetics was first discussed along with its current contribution to the design of rehabilitation robots. With a proposed methodological framework, the design for an upper limb robotic exoskeleton was generated using CATIA software. The design was inspired by the morphology of the bones and the muscle force transmission of the upper limbs. Finally, a full design assembly presented had integrated features extracted from the biological analogue. The successful execution of a biomimetic design methodology made a case in providing safer and more biocompatible robots for rehabilitation. © 2018 Author(s). Published by AIP Publishing
Investigation of energy absorption capacity of 3D filament wound composite tubes: experimental evaluation, numerical simulation, and acoustic emission monitoring
No full textBy analyzing the failure mechanisms, crashworthiness characteristics of FW composite tubes subjected to two modes of progressive damage and catastrophic failure are investigated using acoustic emission technique and numerical method. The AE signals of ±45° composite tubes were classified using hierarchical and wavelet transform methods, and based on the realistic and three-dimensional geometrical architecture of tubular structures, the microstructural finite element model was developed using Catia and ABAQUS software. Then deformation patterns and the impression of each mechanism on the crashworthiness characteristics were assessed. Results indicated that fiber breakage and fiber/matrix debonding could likely control the higher percentage of damage. By changing the type of modes from progressive damage to catastrophic failure, the percentage of matrix cracking increases, the fiber/matrix separation decreases, and the failure behavior become dominated by local buckling. Comparing the FE simulation with experimental results, we found the proposed 3D model can reasonably predict the pre-crushing, post-crushing, and material densification.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Ship Hydromechanics and Structure
Timeline of changes in appetite during weight loss with a ketogenic diet
No full textBackground/objective: Diet-induced weight loss (WL) leads to increased hunger and reduced fullness feelings, increased ghrelin and reduced satiety peptides concentration (glucagon-like peptide-1 (GLP-1), cholecystokinin (CCK) and peptide YY (PYY)). Ketogenic diets seem to minimise or supress some of these responses. The aim of this study was to determine the timeline over which changes in appetite occur during progressive WL with a ketogenic very-low-energy diet (VLED).
Subjects/methods: Thirty-one sedentary adults (18 men), with obesity (body mass index: 37±4.5 kg m−2) underwent 8 weeks (wks) of a VLED followed by 4 wks of weight maintenance. Body weight and composition, subjective feelings of appetite and appetite-related hormones (insulin, active ghrelin (AG), active GLP-1, total PYY and CCK) were measured in fasting and postprandially, at baseline, on day 3 of the diet, 5 and 10% WL, and at wks 9 and 13. Data are shown as mean±s.d.
Results: A significant increase in fasting hunger was observed by day 3 (2±1% WL), (P<0.01), 5% WL (12±8 days) (P<0.05) and wk 13 (17±2% WL) (P<0.05). Increased desire to eat was observed by day 3 (P<0.01) and 5% WL (P<0.05). Postprandial prospective food consumption was significantly reduced at wk 9 (16±2% WL) (P<0.01). Basal total PYY was significantly reduced at 10% WL (32±8 days) (P<0.05). Postprandial active GLP-1 was increased at 5% WL (P<0.01) and CCK reduced at 5 and 10% WL (P<0.01, for both) and wk 9 (P<0.001). Basal and postprandial AG were significantly increased at wk 13 (P<0.001, both).
Conclusions: WL with a ketogenic VLED transiently increases the drive to eat up to 3 weeks (5% WL). After that, and while participants are ketotic, a 10–17% WL is not associated with increased appetite. However, hunger feelings and AG concentrations increase significantly from baseline, once refeeding occurs.© The Author(s) 2017.

Near-infrared spectroscopy (NIRS) as a tool to prevent cerebral desaturation in newborns with bradycardia events: A systematic review
No full textObjective: Near infrared spectroscopy (NIRS) is a non-invasive tool providing real-time continuous measurement of regional cerebral blood oxygenation and indirect blood flow. The aim of this review is to determine the best evidence to guide the use of NIRS to detect and avoid abnormalities of cerebral perfusion and oxygenation in newborns with bradycardia. Design: For this systematic review according to PRISMA Statement, we reviewed papers from 2000 to 2023. Research articles, trial, classical articles, observational studies applying NIRS in term and preterm neonates with bradycardia were selected if the title and/or abstract suggested an association between bradycardia or bradycardia associated with apnoea and modification of cerebral oxygenation. Main results: All included studies (Table 1) were conducted on male and female newborns with gestational age (GA) between 22.6 and 42 weeks and birth weight (BW) between 212 and 3460 g. The definition of bradycardia and cerebral desaturation differed among authors. Seven out of nine papers agreed on association between bradycardia and cerebral desaturation, but no author indicated the cut-off of heart rate (HR) under which cerebral desaturations occur. No study focused on long-term outcome related to cerebral desaturation. Conclusions: Even if cut-off values of HR causing cerebral desaturation are not clear and a well-fixed definition of cerebral desaturation has not yet been standardized, the studies demonstrated that bradycardia events lead to reduction of cerebral saturation. Continuous monitoring of HR and cerebral saturation by non-invasive tools could play a key role in the assessment of newborns
