The shoot apical meristem (SAM) of Sinapis alba can be switched from vegetative to reproductive fate by exposure of 2-month old plants to a single long day (LD). Floral transition then occurs in good synchrony within a population, and a number of biochemical, cellular, and morphological changes have been described. Our aim is to integrate gene expression patterns into this timing. We report here the analysis of SaLFY, orthologous to the floral meristem identity gene LEAFY of Arabidopsis. Materials and Methods: Plants of Sinapis were grown in 8-h shorts days for two months before being induced to flower by one 22-h LD. Shoot apices were harvested 24, 32, 40, 48, 56 and 80h after start of the LD, and prepared for in situ hybridization (Melzer et al., 1999). Results and Conclusions: As expected, the expression of SaLFY was very strong in flower primordia. More surprisingly, SaLFY was expressed well before the initiation of flowers. First, a strong signal was detected in the tip of young leaf primordia of vegetative plants. Secondly, SaLFY was transiently expressed in the SAM of induced plants, from 32h after the start of the LD, when cell proliferation increased. The signal formed, in transverse sections, a discontinuous ring with activation where last leaves were to be initiated. Interestingly, this activation in the SAM matched in time and space early growth changes previously described during the transition to flowering, namely an increase of leaf primordia growth and an acceleration of last leaf initiation (Bernier, 1997), suggesting that SaLFY may have dual functions in fate specification during the floral transition of the SAM.

This paper presents the resolution of a practical hydraulic engineering problem thanks to effective numerical tools. A sedimentation study of the lock of Hun (river Meuse, Belgium) is completed using solid transport models integrated in a finite volume free surface flows solver. The silting of the lock entrance is successfully modelled and various layout modifications of the site are tested to predict their effects and to see to what extent they could improve the actual situation. The analysis of the results shows that a regular dredging of the lock entrance is ineluctable. [less ▲]

There is currently a debate regarding the status of recall and recognition memory in amnesic patients with focal hippocampal damage. Proportionate deficits of recall and recognition memory have been observed in some patients with selective hippocampal damage. In addition, these patients showed an impairment of both the recollection and familiarity aspects of recognition memory. In contrast, other amnesic patients with selective hippocampal lesions demonstrated relatively preserved recognition memory, despite severely impaired recall abilities. In some of them, familiarity processes were found to be intact. The resolution of this controversy has important implications for theories of episodic memory. In the present study, we examined the recall and recognition performance of an amnesic patient, MR, who suffered from bilateral hippocampal damage and temporoparietal cortical atrophy following carbon monoxide poisoning. Verbal and nonverbal recall and recognition memory were measured by tasks matched for difficulty. On these tasks, MR’s recall performance was more severely impaired than his recognition memory. In addition, MR’s recognition performance was normal on most of the tasks. In order to determine on which processes MR based his recognition decisions, we administered to the patient and to matched controls the process dissociation procedure. This evaluates the contribution of recollection and familiarity within a recognition task. The results indicated that, in this patient, familiarity was preserved, but recollection was impaired. This study thus supports the idea that amnesic patients with hippocampal damage can show preserved familiarity-based recognition memory, despite poor recall and recollection. [less ▲]

This paper is devoted to the non linear quasi-steady aerodynamic loading. A linear approximation is often used to compute the response of structures to buffeting forces. Some researchers have however shown that it is possible to account for the non linearity of this loading. This non linearity can come (i) from the squared velocity or (ii) from the shape of the aerodynamic coefficients (as functions of the wind angle of attack). In this paper, we show that this second origin can have significant implications on the design of the structure, particularly when the non linearity of the aerodynamic coefficient is important (obvious, isn’t it?) or when the transverse turbulence is important.

The needs for a building in energy of heating depend on the degree on thermo isolation on its envelope, of its air tightness, the needs for ventilation and its opening to the solar contributions, all parameters which the architect must control to optimize his project. This assessment can be visualized graphically on an abacus, and that simultaneously with the risk of overheating in summer. Paper thus locates the stakes continued by the step of the passive house, in general: to minimize the losses by the envelope, to manage the needs for ventilation and to maximize the solar contributions do not prevent from avoiding the overheating of summer. Passive house JOHANNS built in Kettenis (Eupen) by the architect Leo MICHAËLIS is then presented: project, building site and heat balance. [less ▲]

The state of Minas Gerais (Brazil) exhibits several major karst areas located in sandstone and quartzite terrains, that display a complex suite of underground and surface karstic forms. In the Espinhaço Ridge, central Minas Gerais, several caves, up to a few hundred metres long, occur in the surroundings of the town of Diamantina. Some of these caves, such as Salitre, represent swallow-holes and show dome pits. Other horizontal caves are characterized by corrosion forms generated into the phreatic zone. In some places, such as in the Rio Preto area, these phreatic forms have been overprinted by ceiling tubes, suggesting a polyphase karst evolution, prior to the draining of the cave. Relicts of passages, with circular cross section up to a metre in diametre, can be found amidst the residual tower-like surface landforms, which constitute a typical scenery in the landscape. Their dissection is due to a generalised karstification in the area, resulting in closed canyons, megakarrens and kamenitzas. In southern Minas Gerais, close to the Mantiqueira Ridge, the caves of the state park of Ibitipoca can extent 2 km in length. These caves are associated with a very large hanging geological syncline. Several of these caves contain active streams, that flow for hundreds of metres before disappearing in sand-choked passages. Keyhole cross sections characterize steeply descending passages in these caves, indicating a change from slow phreatic flow towards a faster vadose flow responsible for the vertical incision of the passage. Such change is probably related to base level lowering and/or to turn in the direction of the water flow. Several generations of wall-pockets, from a few centimetres to over a metre long, occur into the caves. These features are good indicators of the initial phase of speleogenesis, generating the initial conduits by their coalescence. This mechanism is also responsible for cut-off meanders. The main river in the area, which flows along the syncline axis, cuts through a rock barrier, generating a tunnel-like passage. This cave drains, through resurgences in its walls, part of the water that flows in other caves located in the flank of the syncline. The non-carbonate karst features observed in the state of Minas Gerais demonstrate the complex organisation of polyphase karst systems due to the linkage of underground and surface forms not previously connected. As in carbonate areas, these systems may play an important hydrological role. [less ▲]

According to recent data (GLC2000 map), African dense forests cover c. 236 million ha, that is 7.9 % of the total continent area. The Central African forest is the last contiguous block of tropical forest in Africa; it covers an area of c. 203 million ha, whereas the forest cover of West Africa (c. 10 million ha) is highly fragmented. At the fringes of the Congo Basin, forests are replaced by woodlands and shrublands, mixed in some places with croplands. Woodlands and shrublands together cover 27 % of the continent, while grasslands represent 15 % of the land. The largest desert in the world is the Sahara desert that covers an area of c. 900 million ha or 33 % of the African continent. Agricultural activities extend over 12 % of the continent. The area of cropland is more important in West Africa than in Central Africa, respectively 16 % and 7 %. Closely related to agriculture, the deforestation rate is higher in West Africa (1.7 % versus 0.4 %). The other causes of deforestation are logging, mining activities, infrastructure development and fires. The most forested countries of the continent are: Central African Republic (c. 8 million ha), Gabon (c. 21 million ha), Cameroon (c. 21 million ha), Congo (c. 26 million ha) and D. R. Congo (c. 125 million ha). These five countries account for 85 % of the African dense forest. In Central Africa, 45 % of the total forest area is under a logging concession status. As a consequence, logging activities play a major role in the Central African rainforest’s future. According to the ITTO (International Tropical Timber Organization) figures, in 2003 the estimated productions of the five previously mentioned countries were: c. 7.4 million m3 of logs; c. 1.1 million m3 of sawn wood; c. 380,000 m3 of plywood and veneer, that is less than 1 % of the world production. Logging in Central Africa is characterized by its high selectivity. For economic reasons, only a few species are commercialized. Usually only one to two trees are felled per hectare and the cover disturbance is about 10 %. The most felled species can be grouped in two categories: hygrophilous evergreen rain forest species and moist semi-evergreen rain forest species. The first category is mainly composed of azobe Lophira alata, beli Julbernardia pellegriniana, douka Tieghemella africana, kevazingo Guibourtia spp., okoume Aucoumea klaineana, pachyloba Afzelia pachyloba, tali Erythrophleum ivorense. The second category is made up of afromosia Pericopsis elata, agba Prioria balsamifera, ayous Triplochyton scleroxylon, dibetou Lovoa trichiloides, frake Terminalia superba, iroko Milicia excelsa, kossipo Entandrophragma candollei, moabi Baillonella toxisperma, movingui Distemonanthus benthamianus, padouk Pterocarpus soyauxii, sapelli Entandrophragma cylindricum, sipo Entandrophragma utile. The major forest companies in the region are mostly subsidiaries of larger European firms (French, German, etc.) although Asian business is becoming more and more important. Obliged by the recent evolution of the Central African forestry laws, some of these logging companies are conceiving forest management plans. The management methods currently implemented were developed as normative regulations issued under the forest laws in the region. The basis of these methods is a statistical inventory of the resources which allows the determination of the population structures, i.e. the number of stems per diameter class. Considering increment and mortality, rotation and/or minimum felling diameters are adapted to reach a satisfactory reconstitution rate. Unfortunately, undamental knowledge about the species population dynamic parameters is still lacking and finally the precision on the rate of reconstitution after a cutting cycle is jeopardized. Moreover, these methods do not pay any attention to long-term preservation of the logged species, since species could have a satisfactory level of reconstitution after one rotation, but could disappear after a second cycle. For such species specific interventions are needed to improve their natural regeneration capacities. In this paper, examples are given for a 176,000 ha management unit in Cameroon for flagship species: assamela Pericopsis elata, ayous Triplochyton scleroxylon, iroko Milicia excelsa, moabi Baillonella toxisperma, sapelli Entandrophragma cylindricum and tali Erythrophleum ivorense. The obtained results attest the need to implement sylvicultural techniques in order to maintain the production capacity of the African rain forests, this production capacity being the best guarantee for the preservation of their integrity.

Carapidae (or pearlfish) are eel-like fishes living inside different invertebrates, such as holothurians, sea stars or bivalves. In some Polynesian areas where they live in sympatry, several species (Carapus homei, Carapus mourlani, Carapus boraborensis and Encheliophis gracilis) are able to inhabit the same host species. The heterospecific infestation rate is very rare, suggesting that the four species can compete for their hosts. Some differences in settlement period, breeding period and in pelagic larval duration (PLD) could allow better characterisation of the life history of each species. More than 700 larvae were collected during an entire year on the Rangiroa atoll (French Polynesia). Each species was identified; their settlement pattern was examined and their PLD was deduced from otolith (sagittae) increments. In the four collected species, the settlement pattern differed: C. homei and C. mourlani settle on the reef during the entire year, and show an asynchronous and diffuse breeding cycle. C. boraborensis and E. gracilis have a shorter settlement period which could be compatible with breeding synchronisation. As most reef fishes, Carapidae larvae mainly settle during moonless nights. Moreover, each species presents some plasticity, allowing it to settle on the reef under suitable conditions. [less ▲]

This paper deals with the consequences of modelling a tapered steel frame with beam elements rather than shell elements. It starts by presenting a specific beam element accounting for the tapering that allows performing geometrically as well as materially non-linear analysis. Then, several kinds of analyses are carried out on two different frames and the results obtained using shell elements, tapered beam elements and prismatic beam elements are compared. This comparison shows that the use of tapered elements leads to results in close agreement with those obtained by shell elements, unlike the prismatic ones. The paper aims at showing that resorting to a so-called segmentation technique should be decided carefully. It also intends at showing the accuracy and convenience of tapered elements when compared to shell models: the total number of degrees of freedom is indeed significantly reduced, leading to easier meshing, shorter computation time and easier interpretation of results.

Locomotor activation is often reported to occur after a systemic administration of low doses of ethanol in most mouse strains, as for example outbred CD1 mice. However, in some strains of mice, such as the inbred C57BL/6J mice, and in rats, systemic injections of ethanol typically induce only a depression of the locomotor activity. Recently, Correa et al. (2003) showed that direct infusions of ethanol in the brain ventricles of rats induced locomotor stimulant effects. These authors suggested that some undefined peripheral effects of ethanol may mask its central stimulant effects when ethanol is administered intraperitoneally. The aim of the present study was to investigate the locomotor effects of either intraperitoneal and intracerebroventricular ethanol administrations in two strains of mice, outbred CD1 and inbred C57BL/6J, that are respectively characterized by the presence and absence of a locomotor stimulant response to ethanol. The results showed that ethanol at moderate and high doses induced locomotor depressant effects in C57BL/6J mice whatever the route of ethanol administration. In contrast, ethanol induced a biphasic effect on locomotor activity in CD1 mice with a stimulant response at low doses followed by a significant sedation. Such a response to ethanol was observed after both peripheral and central administrations of ethanol. The results of the present study demonstrate that the locomotor effects of ethanol in mice are not affected by the route of administration, i.e. peripheral or central. In these rodents, there is no evidence that unidentified peripheral effects of ethanol mask the stimulant ethanol effects. [less ▲]

We present a novel, generic image classification method based on a recent machine learning algorithm (ensembles of extremely randomized decision trees). Images are classified using randomly extracted subwindows that are suitably normalized to yield robustness to certain image transformations. Our method is evaluated on four very different, publicly available datasets (COIL-100, ZuBuD, ETH-80, WANG). Our results show that our automatic approach is generic and robust to illumination, scale, and viewpoint changes. An extension of the method is proposed to improve its robustness with respect to rotation changes. [less ▲]

The aim of this study was to estimate sedimentation rates in floodplains and to investigate lateral channel migrations over the last centuries. Considering the difficulties in determining these parameters using traditional dating methods, we have used different kinds of slag rejected from former metal works. In the Ardenne region (southern part of Belgium), at the end of 14th century, iron factories moved near to rivers in order to take advantage of the hydraulic energy. At the same time, large quantities of slag produced in primitive blast furnaces were piled onto the floodplains, often very close to rivers. Consequently, microslag could be carried away either during floods or by lateral erosion to be deposited on the floodplains downstream. In order to use slag as a stratigraphical tracer, we located slag waste sites along rivers and we dated the periods of furnace activity from historical studies. Afterwards, we measured slag concentrations in the alluvium and we studied their evolutions in different borings. These results allowed us to reconstruct the appearance of the floodplain at the inception of the metal works and to estimate lateral channel mobility over several centuries. Moreover, different kind of tephra and 14C dating have been used in order to date the deposits that have been established before the settlement of metallurgy. [less ▲]

In numerical simulations, it is always necessary to find an optimum between the simplicity of the model and a good representation of real phenomena. In the field of hydraulic flows simulations, the models using depth-averaged and moment equations are an interesting compromise between full 3D and simple depth-averaged models. This paper presents the use of a moment equation for suspended load transport. A simple but representative model for the sediment concentration profiles is developed. This original bi-linear concentration profile is compared to the traditional Rouse-profiles and shows a good correspondence despite its great simplicity. Advective and diffusive sediment fluxes are developed analytically and lead to a concise formulation, which is an asset for practical use. A differential equation for the sediment concentration moment is also fully developed, and a special attention is cast to the source term. The finite volume scheme has been chosen to implement the model, because it is particularly well suited for highly advective transport equations, it is conservative and it makes the choice of the upwinding easier. 1D simulations show the capacity of the model to reproduce laboratory experiments described in the literature.
