Olfactory perception, and especially hedonic evaluation of odors, is highly flexible, but some mechanisms involved in this flexibility remain to be elucidated. In the present study we aimed at better understanding how repeated exposure to odors can affect their pleasantness. We tested the hypothesis of an affective habituation to the stimuli, namely a decrease of emotional intensity over repeti...

Rabbits from three synthetic lines were used in the experiment. Line R was selected for growth for 24 generations. Lines V and A were selected for litter size at weaning for 30 and 33 generations, respectively. Sensory analysis was carried out on the Longissimus muscle. The parameters evaluated were: juiciness (J), hardness (H), fibrousness (F), flouriness (Fl), intensity of rabbit flavour (IRF...

It is shown that surface tension can cause redistribution of melt in a partially molten medium, in accordance with a non-linear diffusion equation for the melt fraction. The associated diffusivity D depends on the surface energy and is positive (stable) for dihedral angle <60 ø and negative (unstable) for dihedral anise >•0ø•1 In the more likely stable case, D ~ . 10 cm .s is typical •or •antle...

Chemical investigation of the aerial parts of Illicium simonsii resulted in the isolation of nine new compounds, simonsols A-E (1-5), simonsins A-B (7-8), terpene-sesquineolignans, clovanedunnianol (9), and p-menthadunnianol (10). Compound 5 was equilibrated with 7 as an inseparable mixture. The structures were elucidated by extensive NMR and MS analysis. Compounds 9, 10, and the mixture of 5 a...

Recent advances in placebo research have demonstrated the mind's power to alter physiology. In this study, we combined an expectancy manipulation model with both verum and sham acupuncture treatments to address: 1) how and to what extent treatment and expectancy effects - including both subjective pain intensity levels (pain sensory ratings) and objective physiological activations (fMRI) - inte...

En parlant de l’œuvre W.G. Sebald, des chercheurs soulignent la « présence muette Shoah » (Dreyfus 2014), et que le sujet reste abordé chez lui plutôt manière oblique (Hunt 2011). C’est précisément cette perspective qui nous intéresse à mettre en l’écrivaine luxembourgeoise Anise Koltz (La lune noircie, 2009) l’auteur belge Paul Willems (Les miroirs d’Ostende, 1978), au moment où ils introduise...
