Belgian draft mares were measured when visiting their owners. The mean wither height of at least 4-year-old mares (n = 207) was 1.64 m and the girth circumference 2.22 m. Compared with the wither height, the hip height was 1 % higher (1.655 m) and the body length 8 % higher (1.775 m). The mean cannon circumference was about 30 cm. The wither height, the body length and the girth circumference of the 2-year-old mares ( n = 39) represented respectively 98 %, 96 % and 94 % of the corresponding measurements of the group of older mares ( at least 4 years old). The morphological characteristics of these last ones, compared with results published about 50 years ago, show that the wither height remained identical whereas body length and width seem to have slightly increased.

In Belgium, the Boom Clay is being evaluated as a potential host formation for the disposal of high-level nuclear waste. In order to investigate this option, an underground research facility composed of two access shafts and 200m of galleries was excavated. Excavation induced fractures were observed in a zone of approximately 1 m around the galleries. In this study, the potential effect of these fractures on radionuclide migration in the Boom Clay is investigated. Therefore, a hydrogeological model of the clay is built with a radionuclide source in the middle of the clay layer surrounded by different fracture configurations. Two types of fracture configurations are inserted in the model. The first type of fracture properties is drawn stochastically from the probability distributions of the properties of the fractures observed around previously excavated galleries. These fracture patterns are considered to be realistic although in this study it is conservatively assumed that no self-sealing occurs. The model is run for a large number of stochastically drawn fracture configurations and the results are compared to a model without fractures. These calculations show that the radionuclide fluxes through the clay are not significantly influenced by these fractures. For the second type of fracture configurations, the fracture properties are varied over a much larger range. Hypothetical fractures with much higher values of fracture extent, aperture, dip and frequency than observed are modeled, With these hypothetical fracture configurations, the critical values of the fracture parameters are determined that must be exceeded to have a significant effect on the radionuclide fluxes through the clay. These calculations show that the extent of the fractured zone has the largest effect on radionuclide migration. The other fracture parameters (aperture, spacing and dip) have a limited effect on the radionuclide fluxes. To obtain a total radionuclide flux through the lower clay boundary that is respectively 10%, 50% and 100% larger than without a fractured zone, the extent of the hypothetical fractured zone should be respectively 27.97 m, 43.86 m and 46.92 m. Such fractures are not expected to be generated by mechanical excavation in the Boom Clay. The obtained critical extent values of the hypothetical fractures are a factor 30 to 40 higher than the measured values of the extent of the excavation disturbed zone. These calculations thus indicate that it is very unlikely that the extent of the fractured zone around the galleries will be large enough to have a significant effect on the radionuclide fluxes through the Boom Clay. This conclusion is further supported by the conservative assumption that no self-sealing occurs. These calculations can function as a preliminary robustness test in ongoing safety analysis studies.

Strained nanowires with varying InAs/InP core/shell thicknesses were grown using Chemical Beam Epitaxy. Microphotoluminescence spectroscopy, performed at low temperature, was then used to study the optical properties of single wires. Emission from the InAs core was observed and its dependence on the shell thickness / core diameter ratio was investigated. We found that it is possible to tune the emission energy towards 0.8 eV by controlling this ratio. We have compared the measured energies with calculated energies. Our findings are consistent with the wires having a hexagonal crystal structure. [less ▲]

We study numerically and analytically the dynamics of passive energy transfer from a damped linear oscillator to an essentially nonlinear end attachment. This transfer is caused by either fundamental or subharmonic resonance capture, and in some cases is initiated by nonlinear beat phenomena. It is shown that, due to the essential nonlinearity, the end attachment is capable of passively absorbing broadband energy at both high and low frequencies, acting, in essence, as a passive broadband boundary controller. Complicated transitions in the damped dynamics can be interpreted based on the topological structure and bifurcations of the periodic solutions of the underlying undamped system. Moreover, complex resonance capture cascades are numerically encountered when we increase the number of degrees of freedom of the system. The ungrounded essentially nonlinear end attachment discussed in this work can find application in numerous practical settings, including vibration and shock isolation of structures, seismic isolation,. utter suppression, and packaging.

Wall-associated kinase 1--WAK1 is a transmembrane protein containing a cytoplasmic Ser/Thr kinase domain and an extracellular domain in contact with the pectin fraction of the plant cell wall in Arabidopsis thaliana (L.) HEYNH. In a previous paper [Decreux, A., Messiaen, J., 2005. Wall-associated kinase WAK1 interacts with cell wall pectins in a calcium-induced conformation. Plant Cell Physiol. 46, 268-278], we showed that a recombinant peptide expressed in yeast corresponding to amino acids 67-254 of the extracellular domain of WAK1 specifically interacts with commercial non-methylesterified homogalacturonic acid, purified homogalacturonans from Arabidopsis and oligogalacturonides in a calcium-induced conformation. In this report, we used a receptor binding domain sequence-based prediction method to identify four putative binding sites in the extracellular domain of WAK1, in which cationic amino acids were selected for substitution by site-directed mutagenesis. Interaction studies between mutated forms of WAK1 and homogalacturonans allowed us to identify and confirm at least five specific amino acids involved in the interaction with homogalacturonan dimers and multimers. The presence of this homogalacturonan-binding domain within the extracellular domain of WAK1 is discussed in terms of cell wall architecture and signal transduction. [less ▲]

Within the periurban areas of big cities, soils are often contaminated by heavy metals spread by human activity: atmospheric fallouts due to industry and traffic, recycling of urban wastes (directly or after water treatment), fertilizers and pesticides used in agriculture… This is, among others, verified in the surroundings of Kunming (Yunnan, PR China) and Lille (Nord-Pas de Calais, France), areas with high density of population and traditional metallurgical industries. These areas have also intensive agricultural activities characterized by important vegetable productions, and are generally known as the "green belts" of the cities. These cultures, with short vegetative period, need high biodisponibility of nutrients, biodisponibility which may also occur for other unwanted elements existing in the soil, such as heavy metals. For evident human health reasons the quality of the crops must be ensured and their heavy metal content kept as low as possible, at least under the values of relevant legal thresholds. Thus, vegetables are particularly sensitive to the presence of heavy metals in the soils where they are growing. It is therefore necessary to manage these soils in order to preserve public health or, more basically, the income of the farmers, as contaminated vegetables would not be marketable. Thus, for these large areas contaminated by diffuse pollution, bioremediation looks to be appropriate. But the kind of the bioremediation which will be applied has to be adapted to the severity of the soil pollution and to the intended land use. In this project, we have assessed the contents of Pb, Cd, Zn and Cu of soils and vegetables within the Chenggong county (near Kunming), and compared the results to the already known situation of the surroundings of two lead and zinc smelters located close to Lille. Then goals and ways of bioremediation have been discussed and the first steps of implementation experimented. [less ▲]
