Dans l'enseignement des activités physiques, les réactions de l'enseignant à la prestation des élèves (feedback) constituent l'une des variables déterminantes dans la réussite pédagogique. Les réactions à la prestation se caractérisent par une grande variabilité interindividuelle. Leur émission fait suite à un processus comportant deux phases: le diagnostic et la prescription. Afin de mettre en évidence le rôle exercé par les facteurs liés aux caractéristiques de l'enseignant sur celles de leurs interventions, nous avons comparé les réactions à la prestation émises par 12 éducateurs physiques lors d'une séance d'enseignement simulé. Grâce à cette technique vidéo, les sujets réagissent à partir de performances motrices identiques. Les feedback ont été comparés entre quatre groupes de sujets caractérisés par des niveaux d'expérience sportive et pédagogique similaires. Une analyse factorielle par correspondance a permis d'identifier des classes de sujets émettant des feedback de même type. Les résultats tendent à souligner que (1) le niveau d'expertise dans la pratique de l'activité enseignée exerce une influence sur la première de ces phases; (2) le degré d'expertise pédagogique contribue à améliorer l'émission du message.

Notre but est de définir une approche multidisciplinaire permettant d'offrir les meilleures chances de guérison ou de survie prolongée aux patientes. Nous nous sommes basés sur notre expérience personnelle et les données actuelles de la littérature, tout en intégrant les approches innovatrices (ex : chimiothérapie intrapéritonéale précoce). Pour certaines patientes, le pronostic reste trop sombre avec un traitement standard et il nous semble important de leur proposer un traitement potentiellement plus efficace. [less ▲]

The purpose of this study was 1) to measure and compare some physiological parameters in horses during a standardised treadmill exercise performed either in temperate atmospheric conditions (TC) (ambient temperature: 15 degrees C; relative humidity: 55%), or in hot and humid conditions (HHC) (ambient temperature: 30 degrees C; relative humidity: 75%) and 2) to follow the recovery of the same horses during 1 h after both tests. Five healthy fit Standardbred horses were investigated twice at 8 days interval, in TC and in HHC. Some measurements were made during a standardised treadmill exercise test (SET), others during a 1 h recovery period. The SET consisted of 8 min warm-up and 8 min exercise. During the SET, respiratory airflow and O2 and CO2 fraction in the respiratory gases were continuously recorded, using 2 ultrasonic pneumotachographs connected to a face mask and a mass spectrometer. Oxygen uptake (VO2), carbon dioxide output, respiratory quotient and expired minute volume (VE) were obtained on a breath-by-breath basis. The maximal values obtained during the highest intensity of the SET and the values obtained 2 min after the end of the test were used for the comparison between both tests. Heart rate (HR) and skin temperature were continuously recorded, using a heart rate recording system and a real time infrared thermographic unit, respectively. After both SETs in TC and HHC, the horses recovered in TC. Heart rate, respiratory frequency (f) and rectal temperature were regularly measured during 1 h after the test. Venous blood was sampled after the completion of the test for biochemical analysis, namely plasma electrolytes and enzymatic activities. Exercising in HHC induced a reduction of the aerobic metabolism to the total energy requirement, i.e. a 20% decrease of VO2 and 55% increase in lactate, as well as a decrease in VE. The increase in rectal and skin temperature, the dehydration and the weight loss were higher in HHC than in TC. During the recovery period the HR and f remained higher up to 30 min after the end of the SET in HHC while the rectal temperature remained higher up to 60 min after the end of this test. Therefore, despite the fact that our horses recovered in TC after exercising in HHC, there were significant differences between their physiological parameters measured during the recovery. This means that the recovery in air-conditioned unit would probably be an insufficient measure to ensure an adequate cooling of the horses and justify consequently the adaptations proposed by the Federation Equestre Internationale (FEI), i.e. the decrease of the distance of the run and the increase of the time devoted to the halt between phases [less ▲]

School physical education focussed on the harmonious development of the individual's various components - namely his motor, cognitive, affective and social dimensions. Within the French-speaking Community of Belgium, as in many other regions in the world, the practive of voleyball comes within the activities proposed in the physical education programme of secondary education. The analysis of activites put forward by physical education teachers shows that volayball is the most practised collective sport in secondary education... [less ▲]

Among various aluminosilicate supports, the K10 montmorillonite clay was the best catalyst for the oxidation of organic substrates with potassium ferrate (VI). Thus, a solid mixture of K2FeO4 and K10 has been used for the efficient oxidation of selected alcohols, benzylamine, thiophenol, and aniline in hydrocarbon solvents at room temperature. Somewhat humid clay performs best, and it is important to control the amount of water associated to the solid support. [less ▲]

We described an exclusively in vitro procedure for cloning and recloning bovine embryos. Embryos obtained by IVM/IVF/IVC developed to the morula stage were used as blastomere donors in cunjunction with IVM recipient oocytes. Reconstructed embryos were developed in vitro in co-culture using bovine oviductal epithelial cells. The resulting morulae were used as donors for recloning under the same experimental conditions. No significant difference was observed between cloning and recloning in terms of development (rates of blastocysts: 12.9 versus 14.9%), in the number of nuclei per blastocyst (63.8 versus 49.1), or in pregnancy rates (35.7 versus 33.3%). The high variability observed between replicates and the correlation between results in first and second cycle nuclear transfer may suggest an inherant potential of individual donor embryos to support development by cloning [less ▲]

The fluctuations of annual precipitation observed in Niamey and Zinder (Niger) since the turn of the century warranted a comparison of rainfall maps and rainy-season characteristics between 1950-1967 (period of high rainfall) and 1968-1985 (period of low rainfall). Calculating two specific annual spatiotemporal rainfall profiles provided precisions as to the irregular and heterogeneous advance of the drought through Niger. [less ▲]
