Memory for times of past events depends on direct impressions of the temporal “distances” of the events in the past and the reconstruction of temporal “locations. Two studies shed light on the possible neurological basis of location-based processes. In an ERP study, adults performed tasks thought to bias subjects to use distance or location processes. Late frontal activity was specifically linked to location-based processes. In another study using the same tasks, aging was found to disrupt location-based processes more than distance-based processes. Age-related differences in the use of location-based processes were mediated by speed of processing and by working-memory capacities. [less ▲]

It is now 30 years since the first motor unit number estimation (MUNE) technique was introduced by Allan McComas as a way of providing an objective, sensitive and reproducible means of measuring the number of motor axons in living human muscle or muscle group. MUNE techniques have substantially evolved over the past decade and have been applied, with increasing frequency, to the study of age effects on motoneurone population and muscle denervating disorders such as amyotrophic lateral sclerosis (ALS), spinal muscular atrophy, poliomyelitis and different types of inherited and acquired peripheral neuropathies. In the future, one of the most important topics involving MUNE, will probably be its use in monitoring the progress of ALS patients undergoing experimental drug trials. However, among incremental, multiple point stimulation, spike-triggered averaging, F-wave analysis and statistical methods, there is no consensus about the best MUNE method. There is only a general feeling that some techniques are more valid than others. For this reason, in the present review, brief descriptions of the distinct MUNE methods are presented. In the second part of the paper, advantages and limitations (alternation, sampling errors, temporal registration etc...) of the most commonly employed procedures are considered. [less ▲]

Near a small city of the Belgian ‘Ardennes’ (East of Belgium), modification of a natural slope for extension of industrial activities has required an extensive drainage in a weathered zone composed of colluvium and weathered claystones and quartzites. After a few days, the drain at the foot of the artificial slope was producing about 1000 m3/day while a natural spring located at a 200 m distance on the hillside was completely dried up. This spring was used for drinking water by the local community. A shallow geophysical prospection by refraction seismics and 2D geoelectrical tomography, associated to geological, morphostructural and hydrogeological observations have lead to a clear understanding of (1) the spring occurrence; (2) the feeding conditions of the spring and consequently (3) the ‘lateral’ hydraulic impact of the drain. In the hill, the bedrock is changing from quartzites (uphill) to claystones (downhill) inducing changes in hydraulic conductivity and thickness of the overlying weathered zone. On the basis of these hydrogeological conditions, associated to the specific topographic conditions, different possible remediation schemas have been proposed to the decision makers. Unfortunately, the full restoration of the natural spring appears to be one of the most technically and financially difficult option …while it is surely the most suitable in the name of a sustainable development.

The simplification of recording procedures constitutes an economic alternative to reduce operational costs when national recording programs are concerned in low input production systems. A total of 54 940 daily milk yields from a herd of 63 Holstein cows recorded in 3 years were used in this study. The effect of reducing tests to measure the accuracy of 305 milk yields was investigated. Two methods of total milk yield computation (the Test Interval Method (TIM) and the Interpolation using Standard Lactation Curves (ISLC)) were compared based on 495 combinations of milk recording alternatives. These alternatives were based on 2 milkings/day, one alternated milking (AM/PM) and one non-alternated milking (AM or PM). All of them were used with 9 intervals between consecutive tests (3 to 11 weeks) and 11 intervals between calving date and the first test day. Results showed that the differences between the actual 305 d milk yield and milk estimated by TIM were the smallest on consecutive test days of maximum 6 weeks of intervals. Differences increased in both sides positively back to A3 and negatively toward A11. Standard estimation errors increased from 4 to 9 from A3 to A11. Phenotypic correlations decreased from .99 to .94 when intervals between the calving date and the first test day increased and this for all test methods (A3-A 11). The ISLC led to a better accuracy of milk yield estimation when intervals between consecutive tests got longer. [less ▲]

The paper covers a brief description and a comprehensive comparative analysis of several state-of-the-art dam breaching models. The study is specifically focused on the applicability and on the predictive capacity of the models for the gradual breaching of an overtopped rockfill dam. A wide range of modelling techniques is reviewed, from process-oriented numerical simulations to empirical models. Comparisons are performed regarding various aspects, such as the applicability of the model without prior calibration or the possibility of coupling the breaching model with a quasi-3D flow solver such as WOLF. Finally, a sensitivity analysis of the downstream hydrograph to various parameters is conducted and the conclusions drawn are illustrated in the case of a large-scale real application in Belgium.

In this paper we consider a tool for analyzing the market outcomes when competitive agents (power producers) interact through the market place. The market clearing mechanism is based on the locational marginal price scheme. A model of the strategic behavior is formulated for the agents. Each agent chooses its bid in order to maximize its profit by assuming that the other agents will post the same bid as at the previous session of the market, and by knowing the network characteristics. The income of each agent over a certain temporal horizon for different power system configurations (the addition of new transmission capabilities, new power plants) is evaluated according to this market dynamics and by integrating this dynamics over the chosen temporal horizon. The mathematical formulation, for the sake of simplicity, is related to a two node power system. In the simulations, the influence of different conditions (line transfer capacity, the number and size of generators, the presence of portfolio) on market outcomes is analyzed, and interesting and sometimes counterintuitive results are found.

In many plant species, flowering is promoted by a long exposure to low temperature, a process known as vernalization. Some plants even have an absolute requirement for winter cold before being able to flower the next summer, hence behave as biennials or winter crops. A recent breakthrough in the understanding of the molecular bases of vernalization has been the cloning of the FLOWERING LOCUS C (FLC) gene in Arabidopsis thaliana (Michaels S.D. & Amasino R.M., 1999). FLC encodes a repressor of flowering and is downregulated by vernalization. So vernalization relieves the inhibitory role that FLC plays on downstream genes involved in the floral transition of the shoot apical meristem (SAM). Although vernalization has been shown, by physiological studies, to be sensed by the SAM, molecular evidences are missing. Such analyses are impaired in Arabidopsis by the small size of the plant and the rosette growth habit. We therefore cloned a FLC homologue in a caulescent relative Brassicaceae: mustard (Sinapis alba L.). We identified two clones by screening a cDNA library made from leaf mRNA. One of them, SaFLC1, was used for in situ hybridizations on SAM sections. Preliminary results are shown. Because of its agronomical importance, we have also tried to manipulate the vernalization process in crops. By using a transgenic approach, we have attempted to bypass the strict vernalization requirement of winter colza (Brassica napus L.). We have over-expressed SaMADS A, a gene which is repressed by FLC in wild type, and observed that the transgenics did not require vernalization any more. [less ▲]

Respiratory disease is the principal cause of loss of young cattle worldwide. The syndrome arises from a number of factors, including those involving the animal, e.g., age, general condition and immune status; its environment, e.g., changes in food, temperature and humidity that lead to stress; and the presence of infectious agents, e.g., bacteria, viruses and mycoplasmas. The syndrome, in a method proposed by the author, can be classified into four grades: Grade 1, subclinical disease; Grade 2, compensated clinical disease; Grade 3, noncompensated clinical disease; and Grade 4, irreversible clinical disease. The increase in frequency and economic impact of bovine respiratory disease complex can be correlated with the escalating industrialisation of cattle production. In intensive operations, commingling of animals from multiple sources, exposure to many organisms, stress and management practices are all factors that can lead to disease. The predisposition of cattle, especially beef calves, to respiratory problems is related to their lack of functional pulmonary hardiness. Selection of breeds that demonstrate adequate pulmonary function and sufficient ventilatory reserve may help in the control of the bovine respiratory disease complex, but this approach is difficult to implement and slow to produce results. Prophylactic measures, including vaccination programmes and modifying management practices to reduce stress, also have a place in preventing the bovine respiratory disease complex. Unfortunately, these measures are not always easy to put into operation and cannot completely eradicate the problem. Therapeutic strategies to minimise the economic impact of the syndrome include use of early antibacterial therapy, modulation of the pulmonary inflammatory reaction and correction of mechanical disorders [less ▲]

In Belgium, respiratory distress syndrome (RDS) is one of the leading causes of neonatal death in the mature hypermuscled Belgian Blue calf (BB) but also occurs in other cattle breeds. Major clinical signs (tachypnea, tachycardia and sometimes depression) develop in the first hours after birth and are due to insufficiency of functional surfactant. Knowing that trace elements deficiencies can slow pulmonary maturation, the aim of this study was to investigate trace elements status in 10 RDS affected BB herds in comparison with 6 reference herds without any evidence of RDS. In each herd, blood was sampled from 10 pregnant or freshly calved healthy cows. In each blood sample, the plasmatic zinc (Zn) and copper (Cu) contents and erythrocytic glutathion peroxydase activity (GSH-pxe) were measured and considered normal when above 15 μmol/L, 14 μmol/L and 250 IU/gHb, respectively. A herd was deficient in one element if at least 30 % of sampled animals were out of normal range for this element. Milk was also sampled and pooled from 10 other cows or, when possible, bulk milk was taken. Milk iodine (I) content was considered normal when above 80 μg/L. Results were compared between groups by Chi-square test. All RDS affected herds had low Zn and Cu concentrations and low GSH-pxe activity. Eight out of 10 had low I in milk. In the non-RDS affected herds, only 1 herd was deficient in I, Zn, Cu and had low GSH-pxe activity, 2 herds were deficient in Zn and Cu and 1 herd was deficient in Cu. RDS affected herds were significantly more often deficient in I and GSH-pxe than non-affected herds. It seems that the trace elements selenium (Se), Zn and Cu play an essential role in the development of RDS. The same applies for I, although not deficient in all herds. The reason for this might be that milk samples were taken during lactation, when cows’ nutrition was different and, in any case, supplemented in I. In mature babies, the same RDS is observed but its etiology is still unclear, although I deficiency in the mother is suspected to play a major role in pathogenesis. Furthermore, it has been demonstrated that a Se-dependent deiodinase is responsible for transformation of thyroxine (T4) into tri-iodothyronine (T3), which is essential for effective surfactant production. In conclusion, results suggest an association between RDS in mature newborn calves and trace elements deficiencies, especially Se and I, that can be responsible for primary surfactant insufficiency.

The verification of a 3D hydrodynamic model of the Ligurian Sea is presented. Two assimilation experiments have been carried out with this model: the assimilation of real SST, and the assimilation of SST forecasted by a statistical predictor. The aim of the study is to establish the skill of the model in these two configurations. The assimilation of predicted SST can help to increase the model skill when observations are not available, and preliminary results show that both approaches obtained similar results. The verification is done in a multi-scale approach, by decomposing the model results and the observations into several spatial scales, using 2D discrete wavelet transforms. At each scale the error between the model and the observations is calculated, and the scales where the biggest errors occur can be identified. The variability distribution of the model and the observations is also examined at each scale, to study the impact of the assimilation on the model variability. This methodology provides a scale-dependent insight in the study of the assimilation of SST and predicted SST. The differences between both assimilated data and how these differences affect the model results are examined. [less ▲]

The paper reports the first results of a work carried out in close collaboration between Astron Buildings SA, a manufacturer of industrial steel buildings, and different groups of civil engineers and mathematicians of the University of Liège to develop an automatic design method for structures with tapered members. This research aims at improving the current method of trialerror followed by experienced engineers to optimize the frames constrained by a chosen national construction code and the technological constraints of the producer. The main benefit of this collaboration arises through the application of a mathematical algorithm based on the sequential quadratic programming method (SQP) in order to reduce, in the first step, the weight of the building, under the great number of constraints. The second step, not yet started, will be devoted to the minimization of the real cost of the frame. This report introduces the first results of this industrial application. [less ▲]

This paper shows the first results of a method of river hydro-geomorphological typology applied on the Euregio Maas-Rhine. This is based on non factorial multivariate analysis (clusters) of only quantitative data automatically extracted from DEM or obtained by field measurements with a simplified protocol. The regional differentiation of variables allows the automatic characterization of rivers especially with the specific stream power. [less ▲]

High Speed Steel (HSS) cast rolls are used in front finishing stands of hot strip mills (HSM). Good wear resistance and hardness at high temperatures, are defining features of HSS. Previous experience has shown that HSS rolls containing mainly hard MC carbides have a high friction coefficient, which is detrimental for the rolling power consumption and for the strip surface quality. On the other hand, HSS rolls containing eutectic rod shaped carbides are brittle and more susceptible to spalling. To overcome these problems, a suitable grade, called HSS7, that gives the best compromise between a low friction coefficient and a high crack propagation and wear resistance was developed. That alloy contains well-dispersed hard VC carbides improving wear, and non-interconnected eutectic carbides of the M2C and M7C3 type, hindering crack propagation. All the metallurgical factors affecting the performance and damage of under rolling condition in front finishing stands are reviewed: wear resistance, friction coefficient, resistance to rolling incident, and oxide film formation. The effect of nature, morphology and amount was for each of the carbides studied and connected to the factor affecting the behaviour of the new grade developed. Different techniques are used such as: differential thermal analysis, optical and electron scanning microscopy and image analysis. A correlation with mechanical properties was also performed.

Proposal of a method of hydro-geomorphological typology of rivers and test of a sub-basin of the Rhône River (Yzeron basin). The paper proposes a hydro-geomorphological typology method of watercourses that might potentially be used in western Europe. The method was tested in the Yzeron basin (France). Field data were collected and analysed by multivariate statistics. Statistical results were consistent with the results of the typology model. Some recommendations are also made for the future development of automatic methods of characterization-sectorization of rivers. [less ▲]

Near Earth Object 2003 EH_1, first seen by LONEOS on 2003 March 6, was identified in early December as the parent of the Quadrantid shower based on the orbit calculated from 48 days of observations following its discovery [1]. The Quadrantids is our most intense annual shower and was until now the only major shower with no parent body. The orbit matches the inclination, semi-major axis, and argument of perihelion of the Quadrantid meteoroids, but has a perihelion distance outside of Earth orbit. It was shown that frequent close encounters with Jupiter result in a rapid dispersion of perihelion distances, accounting for the current orbit of the parent body. The dispersion of orbits in the meteor shower implies a young ˜ 500 year age and the large mass in the stream suggests formation during a comet breakup. This leaves open the possibility that comet C/1490 Y1 was a sighting of the object shortly after it broke up near aphelion, but to match the perihelion time with that of the backward integrated orbit of 2003 EH_1, a better orbit solution is needed. In December and January of 2003, we recovered the object with the ESO New Technology Telescope and computed a much improved orbit. We used that new orbit to study the formation of the Quadrantid stream for various epochs of ejection. In the context of evaluating the NEO impact hazard, those meteoroids trace the orbital evolution of other possible fragments from the breakup 500 years ago that may now be on a collision course with Earth.

Les scientifiques qui ancrent leurs recherches dans le vaste champ des sciences cognitives sont de plus en plus nombreux à s’interroger sur les méthodes qu’ils emploient. De la « connaissance de la connaissance » (Morin, 1986) au « point de vue radicalement en première personne » (Vermersch, 2000a) en passant par la « situation d’étude privilégiée » (Grison, 1998), cette préoccupation épistémologique commence à intégrer progressivement le domaine de l’intervention en sport.
