The dynamics of aroma release during consumption of candies of different structures, and relationship with temporal perception

2011

 ; We investigated the role of both candy texture and eating technique (melting or chewing) on the dynamics of aroma release. One novelty of this type of analysis was the simultaneous application of instrumental and sensory analysis. Four candy textures were established based on their storage modulus at 1 Hz by varying the gelatine content between 0 and 15% w/w. The in vivo release of three aroma compounds was monitored using Proton Transfer Reaction Mass Spectrometry and with a trained panel of testers. The gelatine content had no significant effect on the headspace/product partition and diffusion properties of the aroma compounds. The highest in vivo release for all aroma compounds was ob…

Effect of substrate particle size on burrowing of the juvenile freshwater pearl mussel Margaritifera margaritifera

2021

AbstractJuveniles of the endangered freshwater pearl mussel (FPM,Margaritifera margaritifera) live burrowed in stream substrate for the first years of their life. Fine sediments block water exchange within substrate and may cause juvenile mortality and recruitment failure. To better understand the connection between success of juvenile FPM and substrate particle size, it would be important to understand behavioural responses of FPM to varying substrate sizes at this critical life stage. We placed newly detached FPM juveniles in a 7-mm layer of sieved sand sorted into five sizes (< 120, 120–200, 200–250, 250–500 and 500–650 µm) each with 10 replicate dishes, 10 juveniles per dish, with bu…

Pleasure of eating: a lever for the adoption of healthy eating in children

2018

Childhood obesity, despite a recent stabilization, is still a matter of concerns in the European region and elsewhere (WHO, 2017), i.e. in France (where it concerned 17% of 3-14 y-old children in 2015; INCA3). Since many years, public health campaigns have encouraged healthy eating in many countries over the world, in particular by highlighting the beneficial effect on health of some food groups (e.g., in France “For your health, eat five fruits and vegetables a day”). However, the WHO noted in 2017 that among adolescents, “daily consumption of fruit and vegetables increased slightly between 2002 and 2014, but overall prevalence remains low ; and daily consumption of sugary soft drinks and …

Développement précoce du comportement et des préférences alimentaires

2014

Manger est essentiel pour la survie, et nous naissons équipés pour absorber des nutriments à partir des apports alimentaires. Cependant, l'alimentation ne se résume pas à cet aspect. Quoi, comment, quand, combien manger sont autant de questions qui renvoient à d'autres aspects du comportement alimentaire, auxquelles il nous faut répondre quotidiennement. Ces autres aspects du comportement alimentaire sont appris, essentiellement durant les premières années de vie [1]. Ainsi, nous avons montré que les comportements alimentaires acquis à l'âge de 2 à 3 ans étaient prédictifs des mêmes comportements observés chez le jeune adulte [2,3]. Pour cette raison, il est fondamental de savoir quand et c…

AQUATIC ACOUSTIC NOISE: BEHAVIORAL AND MOLECULAR RESPONSES IN ECHINODERMS, THE CASE OF A. LIXULA (LINNAEUS, 1758) SEA URCHINS

2018

Anthropic noise is considered a real pollutant, in particular the submarine noise. The impact on biodiversity is not yet sufficiently understood. Further research is needed to evaluate any negative effects. The noises associated with anthropogenic activities are increasing: shipments, seismic surveys, sonar, recreational rowing and future mineral extraction activities from ocean depths (DSM). These noises are having an impact on the welfare of many marine species. The understanding of the effects on biodiversity could be important for the creation of guidelines, laws or rules for the most environmentally sustainable exploitation of natural resources. Our study aims to investigate the motili…

Models of the population playing the Rock-Paper-Scissors game

2018

We consider discrete dynamical systems coming from the models of evolution of populations playing rock - paper - scissors game . Asymptotic behaviour of trajectories of these systems is described, occurrence of the Neimark-Sacker bifurcation and nonexistence of time averages are proved.

Un programa de entrenamiento para familiares de pacientes con trastorno límite de la personalidad basado en la terapia dialéctica comportamental

2021

espanolLos familiares de pacientes con trastorno limite de la personalidad (TLP) experimentan ansiedad y depresion, y estan inmersos en un clima familiar disfuncional. Aunque existen tratamientos eficaces para el TLP, se ha prestado menos atencion a los familiares. El objetivo de este trabajo fue adaptar para familiares el entrenamiento grupal en habilidades de la terapia dialectica comportamental, en 14 sesiones. La muestra estuvo formada por 12 familiares: 50% madres, 41,7% padres y 8,3% parejas. Se evaluaron los niveles de depresion (BDI-II), ansiedad (OASIS) y emocion expresada (LEE-S) antes y despues de la intervencion. Los resultados indican que tras la intervencion se produce una mej…

The need for a behavioural science focus in research on mental health and mental disorders

2013

Psychology as a science offers an enormous diversity of theories, principles, and methodological approaches to understand mental health, abnormal functions and behaviours and mental disorders. A selected overview of the scope, current topics as well as strength and gaps in Psychological Science may help to depict the advances needed to inform future research agendas specifically on mental health and mental disorders. From an integrative psychological perspective, most maladaptive health behaviours and mental disorders can be conceptualized as the result of developmental dysfunctions of psychological functions and processes as well as neurobiological and genetic processes that interact with …

The Health Competency Determinant Factors of Latvian Population

2013

Competencies develop and changes throughout a person’s life, they can gain or lose, going through various age stages. Their development does not end in youth, but continue on through the adult life. The ability to thing and reflect those thoughts specifically come forward in the center of structure of competency, which grows at the same time as the individual matures. One of the competency types is health competency. Health competency is a relatively new concept; it is not sufficiently researched. Aim of the study was to determine the factors of an adult individual health competency. 827 respondents participated in the study, in the processing of data was used SPSS. Was used factor analysis…
