Globally, pressure on concentrate feed resources is increasing, especially in the tropics where many countries are net importers of food. Forage plants are a possible alternative but their use as feed ingredients for pigs raises several issues related to their higher fibre and plant secondary metabolites contents as well as their lower nutritive value. In this paper, the nutritive value of several forage species as well as the parameters that influence this nutritive value in relationship to the plant family, the physiological stage, the plant part and the preservation method (fresh, hay and silage) are reviewed. The influence of the breed and the physiological status of the animal on animal voluntary intake of fibre-rich ingredients, digestibility as related to gastrointestinal volume and transit time and growth performances are also discussed. The final section highlights the assets and drawbacks of forage plants in pig diets and stresses the need for proper economic evaluation to conclude on the benefits of the use of forage plants in pig feed.

L’argument de ce XLème Colloque des Hôpitaux de jour psychiatriques nous a plongés dans un abîme de questionnements théoriques et pratiques. Défiés par cette immersion dans les tréfonds du modèle, nous avons choisi de nous accrocher aux fondements de notre univers. La mythologie grecque sera donc notre source d’inspiration en mettant un dieu antique à notre disposition. Chronos sera notre guide dans un périple réflexif soumettant nos théories et notre pratique à l’épreuve du temps. Le récit de la conception d’un atelier thérapeutique, l’atelier « Art & Temps », sera notre fil d’Ariane dans notre tentative de symboliser notre pratique thérapeutique quotidienne et ses enjeux. Par la suite, l’exposé d’un cas clinique concrétisera un raisonnement théorique visant à situer notre modèle de prise en charge dans le réseau psychiatrique global. [less ▲]

One of the bronze plates formerly in the Bianchini collection, which entered the Cabinet des Médailles (Paris) at the end of the 18th century, bears a text and an image, supposedly unintelligible and therefore thought to be of a magic nature. A new examination of this artefact, actually the main part of a bracelet, shows that it depicts an assembly of twenty-eight divinities, illustrating the religious landscape of Egypt in the 2nd-3rd century, and that it is inscribed with two short acclamations. The first one exalts the greatness of the name of Sarapis, the second that of Neôtera the invincible. The identity of this goddess is difficult to define, but she often seems to correspond to a form of Isis assimilated to Korè. The glorifying invocation of these two gods, depicted with their pantheon, may be considered to be an expression of what is today called “megatheism”. [less ▲]

Forage from three species (Adenodolichos rhomboideus, Leucaena leucocephala, Stylosanthes guianensis) were evaluated by determining chemical composition, voluntary intake and apparent in vivo digestibility of dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fibre (NDF) and acid detergent fibre (ADF). Six goats (17.1±0.7 kg) were used in 3 x 3 double latin square design to determine the digestibility and intake of the three forages. Forage from S. guianensis had lower (p<0.001) CP content than L. leucocephala forage and A. rhomboideus leaves. Fibres content (ADF and NDF) were lower (p<0.001) in L. leucocephala (35%) forage than A. rhomboideus (59.5%) leaves and S. guianensis forages (56.5%). L. leucocephala forage was superior in CP, Ash, EE concentrations, digestibility and voluntary intake of CP. A. rhomboideus leaves had lower (p<0.05) apparent digestibility and intake of DM. Digestible CP intake were similar between A. rhomboideus leaves and S. guianensis forages. Low digestibility and voluntary intake of A. rhomboideus leaves may be due to negative effect of anti-nutritional factor such as tannin. Digestible CP was similar for A. rhomboideus leaves and S. guianensis forage. [less ▲]

The aim of this study is to compare the effect of different homogenization treat- 12 ments on the physicochemical properties and the hydrolysis rate of a pure bleached 13 cellulose. Results obtained show that homogenization treatments improve the enzymatic 14 hydrolysis rate of the cellulose fibers by 25 to 100 %, depending of the homogenization 15 treatment applied. Characterization of the samples showed also that homogenization had an 16 impact on some physicochemical properties of the cellulose. For moderate treatment inten- 17 sities (pressure below 500 b and degree of homogenization below 25), an increase of water 18 retention values (WRV) that correlated to the increase of the hydrolysis rate was highlighted. 19 Result also showed that the overall crystallinity of the cellulose properties appeared not to be 20 impacted by the homogenization treatment. For higher treatment intensities, homogenized 21 cellulose samples developed a stable tridimentional network that contributes to decrease 22 cellulase mobility and slowdown the hydrolysis process.

A previous study highlighted the effect of vocal technique on the singing voice accuracy of trained singers (1). The intervals' precision between the notes of the tune was altered when the singers used Western operatic singing technique. In order to better understand these results, we have recorded two different melodies sung with two different vocal techniques. A large panel of trained singers (N = 50) participated in the study. The analytical method described in the reference paper (1) has been applied. The results confirm the effect of vocal technique on the vocal accuracy of trained singers. In addition, these results provide an answer about the melodic effect and guide future work on the perception process of operatic voices. [less ▲]

Background. Numerous students are having school difficulties linked to the way they learn. Some people speak of a “metacognitive deficit”. We refer to a “sleeping potential” instead. Be it psychologists, teachers or parents, all wish to develop their skills in order to help these students. This is the case in primary and secondary school. The EDUCA + project is intended to provide possible solutions. Purpose. The aim of this paper is to present a metacognitive and cognitive theory of learning to learn, which will (a) explain why numerous students are having school difficulties, and (b) predict the success of the EDUCA + project.

Personal identity critically depends on the creation of stories about the self and one's life. The present study investigates the neural substrates of autobiographical reasoning, a process central to the construction of such narratives. During fMRI scanning, participants approached a set of personally significant memories in two different ways: on some trials, they remembered the concrete content of the events (autobiographical remembering), whereas on other trials they reflected on the broader meaning and implications of their memories (autobiographical reasoning). Relative to remembering, autobiographical reasoning recruited a left-lateralized network involved in conceptual processing (including the dorsal medial prefrontal cortex (MPFC), inferior frontal gyrus, middle temporal gyrus, and angular gyrus). The ventral MPFC-an area that may function to generate personal/affective meaning-was not consistently engaged during autobiographical reasoning across participants but, interestingly, the activity of this region was modulated by individual differences in interest and willingness to engage in self-reflection. These findings support the notion that autobiographical reasoning and the construction of personal narratives go beyond mere remembering in that they require deriving meaning and value from past experiences.

Il est maintenu bien reconnu que le vieillissement cognitif est associé à une diminution des capacités exécutives. Toutefois, si des déficits sont effectivement observés au sein des différentes fonctions, des dissociations entre performances préservées/altérées ont également été observées au sein de chacune. Dans cette revue de question, nous détaillerons les effets du vieillissement dans les fonctions de mise à jour, flexibilité, inhibition et coordination de tâches doubles, ainsi que les modifications au sein des réseaux cérébraux associés à ces processus. Nous discuterons également l'influence des capacités attentionnelles, des ressources en mémoire de travail et de certaines caractéristiques génétiques sur ces modifications. [less ▲]

In North Kivu, D.R. Congo, cattle are raised in extensive systems based on local breeds and crossbreds. This farming method affects the performance of dairy animals and mortgages the level of milk consumption in population. An improved farming system, including feed supplementation, Friesian cross-breeding and the sheltering of animals in stalls at night, was studied to evaluate its effect on milk production by Ankole x Friesian crossbreds. The study was performed in Beni, D.R. Congo, on two groups of 15 animals (control group-CoG and improved group-IG), homogeneous according to Friesian blood and parity levels. The improved system, Friesian blood and parity levels increased significantly milk production (P<0.001). Farming system increased milk production by 1.6 l/d (5.2 l/d vs 6.8 l/d respectively in CoG and IG). Milk production ranged from 5.3±0.04 l/d to 6.6±0.02 l/d and from 4.9±0.02 l/d to 7.2±0.02 l/d according, respectively, to Friesian blood level and parity. A significant interaction was observed between farming system and Friesian blood level, and between farming system and parity (P<0.001). The two groups were characterized by a fair adaptation to forage availability associated to climatic factors. The study showed the importance of genetic and environmental factors on the milk production of crossbred dairy cows of the region. [less ▲]

Fatéma Hal, ethnologue et restauratrice marocaine, décrit la nourriture, ainsi que la parole, comme ultime possession dont on ne peut jamais se défaire. On est ce qu’on mange, où qu’on soit. Mais on peut pousser l’analyse au-delà de cela, en affirmant que c’est encore à travers le goût qu’on connait l’autre. Qu’il s’agisse d’ « exotisme culinaire » (Régnier 2004) ou de ce que l’on pourrait définir comme un « cannibalisme exogène », la dégustation des cuisines ainsi dites « ethniques » est une pratique à la mode. Manger l’Autre, pour le connaître ou pour le contrôler ; se faire manger par l’Autre, pour raconter de soi ou pour satisfaire les discours sur l’intégration, témoignent du rôle complexe de la nourriture dans les rapports humains à travers les cultures. L’étude ethnographique que je présente dans cet article vise à illustrer comment certaines femmes marocaines vivant en Italie construisent un savoir culinaire commun, fait de pratiques et de saveurs mobiles, et de quelle façon ce même savoir est acteur du domaine publique.

Recent findings suggest that mind-wandering—the occurrence of thoughts that are both stimulus-independent and task-unrelated—corresponds to temporary failures in attentional control processes involved in maintaining constant task-focused attention. Studies supporting this proposal are, however, limited by a possible confound between mind-wandering episodes and other kinds of conscious experiences, such as external distractions (i.e., interoceptive sensations and exteroceptive perceptions). In the present study, we addressed this issue by examining, in adolescents and young adults, the relations between tasks measuring attentional control abilities and a measure of mind-wandering that is distinct from external distractions. We observed (1) that adolescents experienced more frequent external distractions, but not more mind-wandering, than young adults during the Sustained Attention to Response Task (SART) and (2) that, in young adults, the influence of external distractions on SART performance was fully accounted for by attentional control abilities, whereas mind-wandering was associated with decreases in SART performance above and beyond what was explained by attentional control abilities. These results show that mind-wandering cannot be entirely reduced to failures in the ability to maintain one’s attention focused on task, and suggest that external distractions rather than mind-wandering are due to attentional control failures.
