Role of nitric oxide synthase (NOS) of Klebsormidium nitens: Identification and characterization of partners
2021
National audience; Nitric oxide (NO) is an important cellular signaling molecule across kingdoms. During bioticor abiotic stresses, NO burst is detected in both plants and mammals although no sequenceencoding the well described mammalian NO synthase (NOS) is highlighted in plants. Comparedto terrestrial plants, some algae present transcripts encoding the NOS-like enzyme. Amongthem, Klebsormidium nitens the model alga to study the early transition step from aquatic algaeto land plants is found. As mechanisms governing NO synthesis and signaling in green lineageremain unclear, the study of NOS from K. nitens (KnNOS) through (i) the identification ofregulator proteins, (ii) the identification …
Unravelling some early determinants of liking for vegetables at 2 years: a longitudinal study from pregnancy to 2 years
2014
International audience; Food preferences guide food choices, and impact nutritional status, but their early origin needs clarification. The study aimed at understanding the early determining factors of the liking of vegetables (LVeg) at 2y, taking into account peri- and post-natal feeding experiences, children's acceptance of food tastes and odors and parental feeding practices. In a cohort of children (n 314), the milk, complementary feeding (CF) and table feeding received by children and the diet consumed by mothers during pregnancy/lactation were recorded by diaries. The acceptance of food tastes was evaluated in the lab at 3, 6, 12, 20mo; and of food odors at 8, 13, 22mo. Parental feedi…
Analiza PROFIT i jej wykorzystanie w budowie mapy preferencji parametrów logistycznej obsługi klienta
2017
Artykuł podejmuje problematykę badania preferencji nabywców z wykorzystaniem analizy PROFIT. Jego celem jest wskazanie możliwości zastosowania tej metody w tworzeniu mapy percepcji elementów obsługi klienta oraz korzyści płynących z jej zastosowania. Metoda ta pozwala na identyfikację preferencji odbiorców z punktu widzenia określonych zmiennych.
A novel scientific approach to the conservation of archaeological copper alloys artefacts
2007
A novel research approach focused on innovative materials and methods to assure the long-term stability of bronze archaeological artefacts during exhibition and storage is reported. The work deals with the application of advanced analytical techniques and the development, characterisation and testing of materials and procedures for the conservation, protection and restoration of ancient Cu-based alloy artefacts. Our first aim was the selection of Cu-based alloy artefacts from different archaeological sites in Southern Italy with respect of chemical composition, metallurgical features and corrosion products. This step allowed the identification of the ancient alloys, the study of natural pat…
Understanding physiological and physicochemical influences on in-mouth aroma release from yogurts using mechanistic modelling
2008
International audience; On the basis of a first mechanistic model predicting aroma release in the oropharynx during food consumption, the aim of the present work was to improve its accuracy and to use it to identify the main mechanisms responsible for in-mouth aroma release. Comparison between predicted release kinetics and the ones measured by APCI-MS in the nasal cavity of subjects eating flavoured yogurt highlighted the reasonably accurate time predictions of the relative aroma concentration in the nasal cavity and the model ability to simulate successive swallowing events as well as partial velopharyngeal closure. Parameters identified as the most influent for in-vivo aroma release were…
Visually Induced Motion Sickness on the Horizon
2020
Visually induced motion sickness is an unpleasant but common side-effect of many simulations and VR-applications. We investigated whether an earth-fixed reference frame provided in the simulation is able to reduce motion sickness. To do so, we created a moving starfield that did not contain any indicators of the spatial orientation of the observer. As the observer was simulated to move through the randomly oscillating starfield, a time-to-contact task had to be carried out. Two colored stars on collision course with each other had to be spotted, then they disappeared and the time of their collision had to be judged. Eye-movements, task performance, and motion sickness were recorded. This co…
Towards Automatic Testing of Reference Point Based Interactive Methods
2016
In order to understand strengths and weaknesses of optimization algorithms, it is important to have access to different types of test problems, well defined performance indicators and analysis tools. Such tools are widely available for testing evolutionary multiobjective optimization algorithms. To our knowledge, there do not exist tools for analyzing the performance of interactive multiobjective optimization methods based on the reference point approach to communicating preference information. The main barrier to such tools is the involvement of human decision makers into interactive solution processes, which makes the performance of interactive methods dependent on the performance of huma…

545. Un período fundamental para la climatología española: el “descubrimiento” de la circulación atmosférica en altitud, 1950-1980
2016
El período que transcurre entre los años 1950 y 1980 resulta decisivo para la consolidación de la climatología española. Los trabajos de una serie de geógrafos españoles (López Gómez, García Fernández, Gil Olcina, Burriel de Orueta, Albentosa Sánchez y Capel Molina) se convertirán en referencias básicas al presentar en nuestro país los avances sobre la circulación atmosférica en las capas altas de la troposfera que se desarrollan después de la 2a Guerra Mundial en Estados Unidos y otros países europeos. Este trabajo analiza el contexto científico en el que tiene lugar el “descubrimiento” de la circulación atmosférica en altitud por parte de la geografía española y su repercusión para la mej…
