Sensory and chemical characterisation of Sauvignon blanc wine: Influence of source of origin
2011
Abstract The main objective of the study was to investigate influence of geographical location on volatile composition and perceived flavour profile of Sauvignon wines of New Zealand (Marlborough), French (Sancerre; Loire; Saint Bris), and Austrian (Styria) origin. Nineteen New Zealand wine professionals evaluated 18 Sauvignon wines, 6 from each source of origin, by sensory methods that included intensity ratings to experimenter-provided descriptors, typicality ratings, and classification tasks (non-directed and directed sorting). Results demonstrated that wines from the three sources of origin were separated by sensory analyses, with New Zealand wines dominated by perceived green character…
Spinodal lines and Flory-Huggins free-energies for solutions of human hemoglobins HbS and HbA
1991
Gelation of deoxygenated solutions of sickle-cell human Hemoglobin (HbS) is of high theoretical interest and it has serious pathological consequences. For this reason HbS is probably the most studied protein capable of self-organization. This notwithstanding, the location in the T, c plane of the region of thermodynamic instability of solutions of deoxy-HbS (as bounded by the spinodal line and as distinct from the gelation region) has remained unknown, along with related values of Flory-Huggins enthalpies and entropies. In the present work this information is derived from experiments for the two cases of (deoxy) HbS and of human adult hemoglobin (HbA). Experiments also show critical exponen…
Hyperspectral imaging in perfusion and wound diagnostics – methods and algorithms for the determination of tissue parameters
2018
Abstract Blood perfusion is the supply of tissue with blood, and oxygen is a key factor in the field of minor and major wound healing. Reduced perfusion of a wound bed or transplant often causes various complications. Reliable methods for an objective evaluation of perfusion status are still lacking, and insufficient perfusion may remain undiscovered, resulting in chronic processes and failing transplants. Hyperspectral imaging (HSI) represents a novel method with increasing importance for clinical practice. Therefore, methods, software and algorithms for a new HSI system are presented which can be used to observe tissue oxygenation and other parameters that are of importance in supervising…
EXPLORING THE EFFECTS OF DISCUSSION AND TEXT PLANNING STRATEGIES TO ENHANCE AND ASSESS WRITTEN COMMUNICATION SKILLS
2016
A scuola come nella vita, le capacità di comunicazione scritta sono fondamentali. Queste abilità riguardano soprattutto la costruzione di testi per usi e scopi diversi, l’elaborazione efficace delle informazioni, l’uso corretto della forma linguistica. Scrivere significa conoscere le regole grammaticali ma soprattutto riflettere sulle situazioni e sui contesti specifici di realizzazione, considerare le funzioni linguistiche, gli scopi e i bisogni comunicativi. Sempre più spesso lo sviluppo tecnologico alimenta le difficoltà di bambini e ragazzi di produrre discorsi corretti, coerenti e logicamente organizzati. Per promuovere e valutare la competenza espressiva scritta (strutturazione logica…
Definition of a mutual reference shape based on information theory and active contours
2013
In this paper, we propose to consider the estimation of a reference shape from a set of different segmentation results using both active contours and information theory. The reference shape is then defined as the minimum of a criterion that benefits from both the mutual information and the joint entropy of the input segmentations. This energy criterion is here justified using similarities between information theory quantities and area measures, and presented in a continuous variational framework. This framework brings out some interesting evaluation measures such as the specificity and sensitivity. In order to solve this shape optimization problem, shape derivatives are computed for each te…

Évaluation mettant en balance les risques et les bénéfices relatifs d’autres produits phytopharmaceutiques autorisés ou des méthodes non chimiques de…
2018
La saisine porte sur l’évaluation des intérêts agronomiques et des risques des préparations phytopharmaceutiques (PPP) à base de substances actives de la famille des néonicotinoïdes (NN) et de leurs alternatives : il est demandé, pour les usages autorisés en France des PPP à base de NN, de réaliser une évaluation mettant en balance les risques et les bénéfices des PPP autorisées, ou des méthodes non chimiques de prévention ou de lutte. La demande porte également sur l’incidence économique et les éventuelles conséquences de mise en oeuvre pratique pour l’activité agricole, ainsi que les risques d’apparition de résistances parmi les organismes nuisibles (ON). Cette demande a pris place dans l…
Development of the ETOC : a European test of olfactory capabilities
2003
A number of smell tests designed to evaluate human olfactory capabilities have been published, but none have been validated cross-culturally. The aim of this study was therefore to develop a reliable and quick olfactory test that could be used to evaluate efficiently the olfactory abilities of a European population. This test, named ETOC and based on a combination of a supra-threshold detection task and an identification task, was designed to be a cross-cultural tool that would measure the decline in olfactory performance with ageing. Two versions of the ETOC, one easy and one less easy, were used to test the olfactory performance of European citizens in three countries (France, Sweden and …
