Water table elevations are usually sampled in space using piezometric measurements that are unfortunately expensive to obtain and are thus scarce over space. Most of the time, piezometric data are sparsely distributed over large areas, thus providing limited direct information about the level of the corresponding water table. As a consequence, there is a real need for approaches that are able at the same time to (1) provide spatial predictions at unsampled locations and (2) enable the user to account for all potentially available secondary information sources that are in some way related to water table elevations. In this paper, a recently developed Bayesian data fusion (BDF) framework is applied to the problem of water table spatial mapping. After a brief presentation of the underlying theory, specific assumptions are made and discussed to account for a digital elevation model and for the geometry of a corresponding river network. On the basis of a data set for the Dijle basin in the north part of Belgium, the suggested model is then implemented and results are compared to those of standard techniques such as ordinary kriging and cokriging. Respective accuracies and precisions of these estimators are finally evaluated using a ‘‘leave-one-out’’ cross-validation procedure. Although the BDF methodology was illustrated here for the integration of only two secondary information sources (namely, a digital elevation model and the geometry of a river network), the method can be applied for incorporating an arbitrary number of secondary information sources, thus opening new avenues for the important topic of data integration in a spatial mapping context.

Fertility quantitative trait loci (QTL) are of high interest in dairy cattle since insemination failure has dramatically increased in some breeds such as Holstein. High-throughput SNP analysis and SNP microarrays give the opportunity to genotype many animals for hundreds SNPs per chromosome. In this study, due to these techniques a dense SNP marker map was used to fine map a QTL underlying nonreturn rate measured 90 days after artificial insemination previously detected with a low-density microsatellite marker map. A granddaughter design with 17 Holstein half-sib families (926 offspring) was genotyped for a set of 437 SNPs mapping to BTA3. Linkage analysis was performed by both regression and variance components analysis. An additional analysis combining both linkage analysis and linkage-disequilibrium information was applied. This method first estimated identity-by-descent probabilities among base haplotypes. These probabilities were then used to group the base haplotypes in different clusters. A QTL explaining 14% of the genetic variance was found with high significance (P < 0.001) at position 19 cM with the linkage analysis and four sires were estimated to be heterozygous (P < 0.05). Addition of linkage-disequilibrium information refined the QTL position to a set of narrow peaks. The use of the haplotypes of heterozygous sires offered the possibility to give confidence in some peaks while others could be discarded. Two peaks with high likelihood-ratio test values in the region of which heterozygous sires shared a common haplotype appeared particularly interesting. Despite the fact that the analysis did not fine map the QTL in a unique narrow region, the method proved to be able to handle efficiently and automatically a large amount of information and to refine the QTL position to a small set of narrow intervals. In addition, the QTL identified was confirmed to have a large effect (explaining 13.8% of the genetic variance) on dairy cow fertility as estimated by nonreturn rate at 90 days. [less ▲]

This work presents a numerical study of the behaviour of stainless steel I-beams subjected to lateral–torsional buckling in case of fire and compares the obtained results with the beam design curves of Eurocode 3. New formulae for lateral–torsional buckling, that approximate better the real behaviour of stainless steel structural elements in case of fire are proposed. These new formulae were based on numerical simulations using the program SAFIR, which was modified to take into account the material properties of the stainless steel. [less ▲]

We present an application of X-FEM to the fracture analysis of piezoelectric materials. These materials are increasingly used in actuators and sensors. Under in service loading, phenomena of crack initiation and propagation may occur due to high electromechanical field concentrations. In the past few years, the extended finite element method (X-FEM) has been applied mostly to model cracks in structural materials. The present paper focuses on the definition of new enrichment functions suitable for cracks in piezolectric structures. The approach is based on specific asymptotic crack tip solutions, derived for piezoelectric materials. [less ▲]

The authors have studied selective growth of cadmium telluride on Si(211) by molecular beam epitaxy (MBE). Patterned substrates were produced by optical lithography of MBE-grown CdTe/As/Si(211). Photoemission microscopy was used as the main tool to study selective growth. This is very powerful because Si or SiO2 can be very easily distinguished from areas covered with even small amounts of CdTe due to contrast from work function differences. It was found that CdTe grows on CdTe without sticking on bare Si areas if the temperature is sufficiently high. Based on the analysis of the temperature dependence of the growth rate of CdTe, we suggest that different physisorption energies on Si and CdTe are the main cause of this selective growth.

L’enjeu est de sonder les relations entre le tourisme – sous ses nombreux aspects – la valorisation de la diversité et le développement : envisager l’industrie du tourisme en tant que terrain possible pour un développement partagé entre diverses régions du globe et une opportunité d’insertion professionnelle, notamment, pour la population immigrée en Europe. A quelles conditions, par quelles pratiques ? La première partie du livre s’interroge ainsi sur le « tourisme alternatif » comme espace de valorisation des compétences interculturelles des migrants. La deuxième partie est consacrée à la présentation d’une entreprise de tourisme solidaire et interculturel développant ses activités en Belgique, en Grèce et dans divers pays de l’Afrique. Un copieux chapitre s’enchaîne, ensuite, sur les relations touristiques entre Turquie et Europe : la consommation touristique des communautés immigrées dans leur pays d’origine, l’installation de pensionnés européens dans les villégiatures turques, le fonctionnement des agences immobilières turques de Bruxelles et de Turquie, enfin, le cas des travailleurs migrants dans le secteur du tourisme turc.

Pregnancy diagnosis is an important part in reproduction management of ruminants. The aim of the study was to use a new method for evaluating the bPAG and cPAG in milk and blood bPAG and compare this results with the other method for pregnancy diagnosis in the cows. The study was carried out in 220 Holstein Frisian cows. Heparinised blood samples were taken from the jugular vein and stored at -20 degrees C until PAG assay by RIA. For bPAG and cPAG, RIA test, milk samples were homogenized. Pure bPAG was used as a standard tracer described by Zoli et al. (1992). The cows were diagnosed as pregnant by means of USG (Aloka SSD 210) and by rectal palpation. bPAG and cPAG concentration in milk increased after 28 day of pregnancy and showed the rapid increase near the parturition. The same results of bPAG concentration we obtained in the blood samples. The decline of bPAG concentration was faster in the milk than in the blood. The data showed that the RIA method is precise enough to measure PAG concentrations in the maternal blood and milk of cows. The data indicate that milk samples can be used for pregnancy diagnosis in cows. The sensitivity and specificity of RIA measurement of PAG are very high. [less ▲]

The mouthbrooding cichlid Oreochromis niloticus is one of the world’s best-studied fish and is raised extensively for aquaculture. Although it is a common behavioural model, its acoustic communication has been neglected. Because of extensive parental care, the species is a good candidate for vocal learning. In male O. niloticus, we investigated for the first time sound production in agonistic interactions during nest construction. Males produce short-duration (250– 400 ms), often double-pulse sounds. Most energy is below 200 Hz and includes three main low-frequency peaks although energy extends beyond 1 kHz. Males (separated as eggs and raised in isolation) produce similar sounds in the same context as parental fish, indicating that the ability to produce sounds and the basic properties of the sounds are innate.
