Partly damaged by fire during the sack of the city of Dinant by Charles the Bold in 1466, the collegiate church of Dinant went through a long and expensive restoration from the year 1472 onwards. Combining the study of the archival evidence with the archaeological analysis of the building itself, this article aims to reassess the extent of this restoration, which had never been studied thoroughly. This paper also seeks to describe the chronology of these operations as well as the building processes at work. [less ▲]

En 2004, Bertrand Daunay et Jacques Treignier (2004) indiquaient que les pratiques langagières enseignantes constituaient une problématique émergente en formation initiale et continue des enseignants. Ils mentionnaient alors quelques travaux en littéracies universitaires, champ qui s’est considérablement étoffé, mais soulignaient que l’oral était peu étudié. Depuis lors, plusieurs publications sont apparues concernant les écrits professionnels des enseignants : Daunay (2011), Cadet & Rinck (2014), Bride & Chenot (2015), Ronveaux (2015), en plus des travaux pionniers entrepris par et autour de Dominique Bucheton au sujet des conduites orales en classe (voir notamment Bucheton & al., 2004 ; Bucheton & Dezutter, 2008 ; Bucheton & Soulé, 2009). À la suite de Dominique Bucheton et al. (2004), je soutiens que le langage constitue la dimension centrale de l’activité enseignante, qu’il soit écrit ou oral. Dans une perspective vygotskienne (1997 [1931], 2014 [1934]), je considère en effet que les verbalisations enseignantes constituent des médiations décisives dans le processus d’apprentissage des élèves. Ces traces sémiotiques diverses constituent véritablement des outils au sens vygotskien (1934-1997, 1931-2014), donc des dimensions susceptibles de soutenir chez les élèves des fonctions psychiques supérieures (mémoriser, problématiser…). Les verbalisations enseignantes constituent des médiations décisives, donc des intermédiaires, des interfaces, entre l’élève et le savoir. À ce titre, ces pratiques langagières fondatrices de l’agir enseignant méritent d’être mieux cernées. La présente contribution se propose d’étudier les verbalisations écrites et orales déployées par les enseignants autour des journaux des apprentissages, journaux réflexifs par lesquels élèves du primaire et du secondaire sont invités à secondariser (Bautier & Goigoux, 2004) les apprentissages réalisés en classe : autrement dit, ils adoptent à leur égard une posture exotopique, une posture de surplomb. Cette analyse de l’activité interactive et dynamique « enseignant/élève » repose sur une conception qui articule contenus d’enseignement et pratiques langagières scolaires, tandis qu’elle vise à décrire « le détail ordinaire du quotidien » des praticiens (Bucheton, 2008).

L’initiation à l’écriture scientifique telle qu’elle se décline dans les mémoires de Master peut se focaliser sur plusieurs de ses dimensions, mais la capacité à élaborer une problématique est peut-être l’une des exigences les plus complexes qui se pose au chercheur néophyte. Cette contribution envisage des travaux dans lesquels les étudiants doivent tout à la fois rendre compte d’un ouvrage lu, formuler et étayer un avis critique à son encontre avant de concevoir la problématique qui sera traitée dans leur mémoire. Une analyse sociolinguistique des données révèle trois logiques scripturales contrastées : émergent en effet des discours restitutifs (il s’agit de donner à voir), critiques (il s’agit de faire croire) ou problématisants (il s’agit de faire savoir). La question de la place dévolue à la linguistique, tant en termes de formation que de recherche, sous-tend toute la réflexion. [less ▲]

Specific training and competition management necessitates information about exercise intensities and fitness, which are usually assessed by standardized exercise tests. Our purpose was to identify parameters whose measurement can be largely integrated in the daily training and competition routine and which provide information on fitness and adequacy of applied training. Further, we evaluated training and competition intensities of eventing horses, based on data generated by a proportionally large group of horses over several years. Data of 187 horses from 1-star to 4-star level over a time period of six years were collected during 410 training sessions and 916 Cross Country rides, including measurement of covered distance and speed (GPS, Fidelak EquiPILOT), continuously recording of heart rate (HR) (Polar T52H) and determination of blood lactate concentrations (BLC) (Dr. Lange photometer). Characteristics of the track, altitude profile, ambient temperature and humidity were recorded at each session. The results of the one-way ANOVA indicated a significant effect of competition level on HR (F3,373=23.29; p<0.001) and BLC (F3,763=46.12; p<0.001). Under competition conditions, HR and BLC increased from 1-star to 3-star level (1-star: HR=194±9 bpm, BLC=7.7±5.6 mmol/l; 2-star: HR=198±9 bpm, BLC=9.6±6.2 mmol/l; 3-star: HR=205±10, BLC=15.6±9.8 mmol/l; 4-star: HR=207±2 bpm, BLC=12.4±9.3 mmol/l), while under training conditions, they decreased with increasing competition level (1-star: HR=184±29 bpm; BLC=18.9±11.1 mmol/l; 2-star: HR=182±19 bpm; BLC=12.1±9.0; 3-star: HR=174±25 bpm; BLC=6.9±7.1 mmol/l; 4-star: HR=161±24 bpm, BLC=4.0±5.6 mmol/l). On 1-/2-star level, BLCs after training exceeded those after competition. Reverse applied for 3-/4-star level. On 3-star level, the percentage of HRs above 200 bpm during Cross Country was considerably greater than on lower levels (1-star: 33%; 2-star: 54%; 3-star: 94%). The competition format (CCI/CIC) had no significant effect on the progress of HR. The altitude profile however, had a significant effect on HR (F1,201=26.72, p<0.001) and BLC (F1,89=25.56; p<0.001). Evaluation of physiological response to training and competition through implementation of measurement technology allows an assessment of the different impacts on exercise intensities and should be more commonly used to assess appropriateness of training and competition management in eventing horses. It should be further investigated if the detected discrepancies in the response to training and competition between levels are a result of different fitness ore varying training strategies. LP To meet the demands of international Eventing competitions, a systematic training of horses is necessary. Close monitoring of physiological response to exercise during training and competition can help to improve training. Keywords Exercise physiology; training; eventing; heart rate; lactate. [less ▲]

Knowing that polyunsaturated fatty acids can lead to the formation of potentially toxic aldehydes as secondary oxidation products, an analytical method using liquid chromatography coupled to tandem mass spectrometry detection (LC-MS/MS) has been developed to evaluate the concentration of eight aldehydes in animal feed: malondialdehyde (MDA), 4-hydroxy-2-nonenal (4-HNE), 4-hydroxy-2-hexenal (4-HHE), crotonaldehyde (CRT), benzaldehyde (BNZ), hexanal (HXL), 2,4-nonadienal and 2,4-decadienal. The developed method has been validated according to the criteria and procedure described in international standards. The evaluated parameters were: specificity/selectivity, recovery, precision, accuracy, uncertainty, limits of detection and quantification, using the concept of accuracy profiles. These parameters have been determined during experiments realized on 3 different days with grounded Kellogg’s® Corn Flakes® cereals as model matrix for animal feed and spiked at different levels of concentration. Malondialdehyde, 4-HHE, 4-HNE, crotonaldehyde, benzaldehyde and hexanal can be analysed in the same run in animal feed with a very good accuracy, with recovery rates ranging from 86 to 109% for a working range going from 0.16 to 12.50 mg/kg. Concerning 2,4-nonadienal and 2,4-decadienal, their analysis can be realized as well but in a limited range of concentration and with a limited accuracy. Indeed, recovery rates ranged between 54 and 114% and coefficient of variation for the intermediate precision between 11 and 25% for these two compounds. [less ▲]

This paper addresses the problem of an aggregator controlling residential heat pumps to offer a direct control flexibility service. The service is defined by a 15 minute power modulation, upward or downward, followed by a payback of one hour and 15 minutes. The service modulation is relative to an optimized baseline that minimizes the energy costs. The potential amount of modulable power and the payback effect are computed by solving mixed integer linear problems. Within these problems, the building thermal behavior is modeled by an equivalent thermal network made of resistances and lumped capacitances whose parameters are identified from validated models. Simulations are performed on 100 freestanding houses. For an average 4.3 kW heat pump, results show a potential of 1.2 kW upward modulation with a payback of 600 Wh and 150 Wh of overconsumption. A downward modulation of 500 W per house can be achieved with a payback of 420 Wh and 120 Wh of overconsumption. [less ▲]

The aim of this study is to propose the application of a network approach to historic urban landscape conservation. Network approaches in landscape ecology and urban studies have been applied in various ways. In a natural landscape, the ecological network model has been applied to conserve biodiversity. The model consists of core areas, corridors, and buffer zones (Cook & van Lier, 1994; Jongman, 2004).In urban studies, the network metaphor has a long tradition especially in transportation planning. More recently, urban design has brought its contribution by different means. Three of these means are: (i) the space syntax method; (ii) the urban ecological network planning; and (iii) the development of heritage corridors for cultural heritage conservation. As urban landscapes are complex, there have been a multiplicity of methods, and graphical representations to the design of networks. In this context, the application of a network approach to urban cultural heritage conservation poses several questions: what method to use to identify the nodes and links? What kind of attributes to investigate? To answer these questions this study investigates the different types of heritage nodes, and corridors existing in an urban context: cultural, historic, functional, visual, and physical. [less ▲]

Air-ice CO2 fluxes were measured continuously using automated chambers from the initial freezing of a sea ice cover until its decay. Cooling seawater prior to sea ice formation acted as a sink for atmospheric CO2, but as soon as the first ice crystals started to form, sea ice turned to a source of CO2, which lasted throughout the whole ice growth phase. Once ice decay was initiated by warming the atmosphere, the sea ice shifted back again to a sink of CO2. Direct measurements of outward ice-atmosphere CO2 fluxes were consistent with the depletion of dissolved inorganic carbon in the upper half of sea ice. Combining measured air-ice CO2 fluxes with the partial pressure of CO2 in sea ice, we determined strongly different gas transfer coefficients of CO2 at the air-ice interface between the growth and the decay phases (from 2.5 to 0.4 mol m−2 d−1 atm−1). A 1D sea ice carbon cycle model including gas physics and carbon biogeochemistry was used in various configurations in order to interpret the observations. All model simulations correctly predicted the sign of the air-ice flux. By contrast, the amplitude of the flux was much more variable between the different simulations. In none of the simulations was the dissolved gas pathway strong enough to explain the large fluxes during ice growth. This pathway weakness is due to an intrinsic limitation of ice-air fluxes of dissolved CO2 by the slow transport of dissolved inorganic carbon in the ice. The best means we found to explain the high air-ice carbon fluxes during ice growth is an intense yet uncertain gas bubble efflux, requiring sufficient bubble nucleation and upwards rise. We therefore call for further investigation of gas bubble nucleation and transport in sea ice. [less ▲]

Chemical signals are involved in the courtship behavior of many invertebrate and vertebrate species. Lady beetles are no exception to this rule; a significant number of published reports highlight the role of cuticular chemicals involved in the reproduction of lady beetles, including gender recognition. Recent data have also demonstrated the presence of a volatile female sex pheromone that facilitates male attraction in some species. Here, we present a synthetic overview of the current knowledge about the sexual behavior of lady beetles and associated chemicals for which the function and identification have been provided. Because lady beetles are often reared as biological control agents, the chemical cues involved in their sexual behavior could be used as components in integrated management approaches against soft-bodied hemipterans. In conclusion, this review provides new perspectives and potential developments for sustainable insect management mainly based on the semiochemicals involved in the sexual behavior of lady beetles. A better understanding of these chemical signals would help maximize their presence in areas where their predatory behavior is requested, as a result of the application of formulations inducing behavioral manipulation.
