In this paper, I review various questions related to the relationships between banks and private clients, taking into account the impact of the entry into force of the Belgian Code of Private International Law. Among the questions analysed, I review the position of the bank when faced with clients who are married and the impact of the law of marriage. I also review the impact of the death of a client - what are the duties imposed to the bank, how can the bank deal with prospective heirs. All of this focusing exclusively on cross-border relations and hence on questions of applicable law. [less ▲]

Previous studies have described high levels of polychlorobiphenyls (PCB), polybrominated diphenylether (PBDE), toxaphene, ,p0-dichlorodiphenyltrichloroethane (DDT), and ,p0-dichlorodiphenyldichloroethylene (DDE) in the blubber of the harbour porpoise from the North Sea raising the question of a potential endocrine disruption in this species. In the present study, the thyroids of 57 harbour porpoises from the German and Danish (North and Baltic Seas), Norwegian, and Icelandic coasts have been collected for histological and immunohistological investigations. The number of follicles and the relative distribution of follicles, connective, and solid tissues (%) were quantified in the thyroid of each individual. Then, the potential relationship between the thyroid morphometry data and previously described organic compounds (namely, PCB, PBDE, toxaphene, DDT, and DDE) was investigated using factor analysis and multiple regressions. Thyroid morphology differed strongly between ampling sites. Porpoises from the German (North and Baltic Seas) and Norwegian coasts displayed a high percentage of connective tissues between 30 and 38% revealing severe interfollicular fibrosis and a high number of large follicles (diameter >200 lm). A correlation-based principal component analysis (PCA) revealed two principal components explaining 85.9% of the total variance. The variables PCB, PBDE, DDT, and DDE compounds loaded highest on PC1 whereas toxaphene compound loaded most on PC2. Our results pointed out a relationship between PC1 (PCBs, PBDE, DDE, and DDT compounds) and interfollicular fibrosis in the harbour porpoise thyroids. Such an association is not alone sufficient for a cause–effect relationship but supports the hypothesis of a contaminant-induced thyroid fibrosis in harbour porpoises raising the question of the longterm viability in highly polluted areas.

Various animal models have been developed to investigate the neurobiological and behavioral mechanisms of drug addiction. The most popular of these animal models include the locomotor sensitization paradigm, the place conditioning procedure and the self-administration technique. With these techniques, it is possible to mimic in rodents the major aspects of human drug addiction. The self-administration procedure is the most widely used and show an excellent natural and predictive validity. In the self-administration protocol, experimental animals, usually rats or mice, are allowed to press a lever in order to gain access to a small dose of an addictive drug. The drug may be given to the animal through the oral, the intravenous or the intracranial route of administration, according to the purpose of the study. In recent years, the classical self-administration procedure has been adapted to study the specific neurobiological basis of drug relapse. In this now called drug reinstatement paradigm, when drug self-administration behaviors are well established, an extinction procedure starts, during which lever pressing is no longer reinforced by drug access. After a number of such extinction sessions, lever pressing gradually declines and eventually stops. Drug-seeking behaviors are therefore said to be extinguished. It is then possible to test various stimuli in order to investigate whether they reinstate drug-seeking behaviors and use such a reinstatement as an animal model of drug relapse. Three types of stimuli have been shown to reinstate drug-seeking behaviors: a small priming dose of drug, drug-associated cues and a stressful stimuli. The effects of these three relapse-triggering stimuli are mediated by different neurobiological mechanisms, leading to the expectation that they may be targeted by different pharmacotherapeutic and behavioral interventions. Despite the high value of the current animal models of drug addiction, there show several limitations. In particular, it is difficult to differentiate between self-controlled and compulsive drug use in animals. As only uncontrolled compulsive drug consumption characterizes drug addiction in humans, such a limitation might explain the high frequency of false positive results in animal experiments. Indeed, it is common that therapeutic interventions successfully developed in animals later proved to be disappointing in humans. [less ▲]

Studies of lysozyme have played a major role over several decades in defining the general principles underlying protein structure, folding, and stability. Following the discovery some 10 years ago that two mutational variants of lysozyme are associated with systemic amyloidosis, these studies have been extended to investigate the mechanism of amyloid fibril formation. This Account describes our present knowledge of lysozyme folding and misfolding, and how the latter can give rise to amyloid disease. It also discusses the significance of these studies for our general understanding of normal and aberrant protein folding in the context of human health and disease. [less ▲]

In civil engineering applications the dynamic analysis of large structure is often performed in a modal space. This method is known to offer an interesting decrease of the number of degrees of freedom as well as a decomposition of the structure’s response in “uncoupled” components. Even if the response in each mode can be computed independently from the responses in the other ones, in the context of stochastic loading, the coherence of these modal responses must be accounted for in the determination of the structural response. These quantities are known as the modal cross-correlations. In this paper we will show that these crosscorrelations can be important (contrarily to what is sometimes thought) even in case of wellseparated natural frequencies. This will be illustrated on the analysis of the famous Viaduct of Millau during an erection stage. [less ▲]

In the context of a non linear quasi-steady wind loading, this paper shows the importance of the non linearity of the wind loading. More particularly, it focuses of the influence, on the structural response, of the non linearity of the aerodynamic coefficients. It is shown that, in case of 2-D turbulent flow, the influence of this kind of non linearity may be significant. To do so, statistical characteristics of the loading as well as those of the response are computed in such a turbulent flow. [less ▲]

Arab Islamic landscape design forms a unique source of inspiration for landscape architecture in barren open spaces of the Middle East. Arab Islamic gardens adopted a system marked by perfect responsiveness to environment. The design of urban landscape and gardens in Arab Islamic culture was similarly guided by the dictation of aridity. The need to provide shade, to prevent dust and to conserve water meant that urban open spaces and gardens were sheltered and enclosed. Alhambra in Moorish Spain and the Al-Suhaymi House in Islamic Cairo are two useful historical references for vernacular Islamic landscape designs. This paper presents an overview of landscape design considerations for the composition of vegetation and water and initial observations of their influence in controlling and improving the microclimate in courtyards buildings as a way of passive cooling in the Middle East region. This paper is a part of a Master’s thesis in the field of passive landscape strategies at Wageningen University. The objective is to identify the comfort improvements potential of successfully-planned and integrated landscape design in traditional courtyard buildings. The layout and plant material of Alhambra, Generalife courts and Al-Suhaymi court in Islamic Cairo are examined and evaluated. This study demonstrates that in arid environments, the landscape planning, the composition of vegetation and water and choice of planting material all have important consequences in creating thermally-pleasant environments.

In Wallonia, railways constitute valuable habitats for reptile conservation. All autochthonous species have colonized these man-made habitats, but their presence and abundance largely vary among the natural regions and the kinds of railways. Reptiles are more frequent along railways with remaining rails than along dismounted unused ways, which represents one half of the network. Although representing only a small part of the network, the unused railways not dismounted are particularly rich in reptiles. This is also the case of some active lines in sunny areas of large valleys and in some large switchyards. Anguis fragilis is the most widespread species on the Walloon railways, but P o d a rcis muralisis the most abundant. In Wallonia, railways seemed to have contributed to the local, more rarely regional, dispersion of at least five species of reptiles: Anguis fragilis, Lacerta agilis, Podarcis muralis, Zootoca viviparaa and Coronella austriaca. Some of these species – specifically Podarcis muralis– have most probably colonized new regions through unexpected transportation by merchandise cars. Finally, reptile populations inhabiting the Walloon railways face several threads. [less ▲]

This article presents some basic aspects of a research about the evaluation of the effect of earthquakes on storage racking systems. In particular, it focuses on the possible sliding and friction of the stored good subjected to a horizontal inertial force. In the first part, a theoretical SDOF system is studied to derive general indications on the sliding behavior and to serve as a reference for the validation of a more advanced numerical model. The second part presents then an application of the numerical model to simple rack structures. [less ▲]

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.
