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.

Networks of associated words are used in qualitative data analysis software such as Candide, Réseau-Lu T-Lab on one side and Prospéro on the other side. The precise algorithm of both Candide and Prospéro is described. Strength and limits of such a feature are compared with the gain it provides to social scientists. The paper concludes on a procedure helping to judge the adequacy and accuracy of categories of analysis constructed by the researcher. [less ▲]

The main objective of our dissertation was to contribute to a better understanding of the cognitive processes involved in episodic memory and their cerebral substrates. More specifically, our work focused on two questions. First, we were interested in the contribution of recollection and familiarity to recognition memory. On the one hand, we examined the performance on recognition tasks when recollection cannot be used anymore (studies 1, 2 and 3) and, on the other hand, the influence of frontal lobe lesions on the processes involved in a recognition memory task (study 4). Second, we explored the processes recruited in an important aspect of episodic memory, namely, memory for the temporal context of events, by studying the nature of the difficulties encountered by older adults on a task assessing memory for temporal information (studies 5 and 6).

It has long been thought that, of all EU competition processes, merger regulation was immune from arbitration. This has changed dramatically over the last few years. Starting in 2000, the European Commission accepted, albeit reluctantly, to consider behavioural commitments made by merging entities. In the past, the Commission had considered that such commitments were not adequate to ensure competitive market structures. Compliance with structural remedies can be monitored fairly easily by the Commission. Structural commitments entail mostly divestments needed to maintain an acceptable level of competition. Behavioural commitments, however, require more extensive monitoring, since they concern the future behaviour of the merged entity. Monitoring these commitments is time consuming and the Merger Task Force (MTF) does not have the necessary resources to do so. One of the solutions favoured by the MTF to monitor compliance with these new commitments, is to impose an arbitration agreement to the merged entity. The article examines the difficulties posed by the arbitration process in this context [less ▲]

This paper explains how the dynamic approach has been implemented in the computer software SAFIR in order to cope with temporary and local failures that occured in a step be step static analysis of structures subjected to fire.By means of this recently implemented dynamic algorithm, it’s now possible to simulate the complete failure mechanism, to predict the influence of a local failure on the global behaviour of the structure and to follow eventually the progressive collapse. Therefore the resistance time is now really determined whereas in the past many numerical failure corresponding to local failure were interpreted as resistance time of the whole structure. [less ▲]

Two-colour sum-frequency generation (two-colour SFG) spectroscopy was used to probe both vibrational and electronic properties of 1-dodecanethiol/Ag(1 1 1), Au(1 1 1), and Pt(1 1 1), of 5-[p-(6-mercaptohexoxy)-phenyl]-10,15,20-triphenylporphin/Pt(1 1 1), and of C60/Ag(1 1 1). The role of the various physical parameters determining the sum-frequency generation (SFG) intensity equation is highlighted. The enhancement of the non-linear second order susceptibility in the aforementioned interfaces is explained in terms of metal interband transition, molecular electronic transition and of electron–phonon coupling, respectively.

In the frame of a FIRST-Europe project, the research team worked with a partner from university of Barcelona (Spain) and a company fabricating products to reduce moisture problems in dwellings. An original instrument was designed. It was based on the "electronic nose" principle. With suitable data processing tools and an adequate calibration, the instrument was able to distinguish, from the analysis of the gas phase, the emission of the clean material from the one of the same material contaminated by moulds and from the one of the product against humidity. Discriminating between different mould species was more difficult. [less ▲]
