The ALADDIN concept is an integrated Antarctic-based L-band experiment whose purpose is to demonstrate nulling interferometry and to prepare the DARWIN mission. Because of their privileged location, the relatively modest collectors (1 m) and baseline (up to 40 m) are sufficient to achieve a sensitivity (in terms of detectable zodi levels) which is about twice better than that of a nulling instrument on a large interferometer (such as GENIE at the VLTI), and to reach the 20-zodi threshold value identified to carry out the DARWIN precursor science. These numbers are based on a preliminary design study by Alcatel Alenia Space and were obtained using the same simulation software as the one employed for GENIE. The integrated design enables top-level optimization and full access to the light collectors for the duration of the experiment, while reducing the complexity of the nulling breadboard. [less ▲]

The authors present a novel nonlinear homogenization technique for laminated iron cores in three-dimensional (3-D) finite-element (FE) models of electromagnetic devices. The technique takes into account the eddy current effects in the stacked core without the need of modeling all laminations separately. A nonlinear constitutive magnetic law is considered. The system of nonlinear algebraic equations obtained after time discretization is solved by means of the Newton-Raphson scheme. By way of validation, the method is applied to a 3-D FE model of a laminated ring core with toroidal coil. [less ▲]

In less than ten years, a corporate property market has emerged in Wallonia. This market first covered offices and retail units and recently extended to semi-industrial establishments. Its development is largely related to the creation of a new type of demand resulting from the growth of new service activities and from new expectations regarding physical units, environment, accessibility and location choices – on both sub-regional and local scales. It has been favoured by the appearance of new property stakeholders, Belgians as well as foreigners (developers, investors and estate agents), but also by public authorities (the Walloon Region and economic development supra-communal agencies). This market’s emergence is related to the deepening of territorial contrasts as property development projects usually reinforce strong areas. [less ▲]

REASON FOR PERFORMING STUDY: In man, exercise of any type has been shown to induce neutrophil degranulation and respiratory burst activity, as well as an increase in plasma myeloperoxidase (MPO), a specific enzyme of neutrophil azurophilic granules with a strong oxidative activity. Until now, it is not known whether this is the same in horses. OBJECTIVES: To study whether degranulation of blood neutrophils may be induced by exercise by measuring the total concentration of MPO and assess the possible influence of type of competition on this exercise-induced adjustment. METHODS: Blood was sampled before, and 30 min after, the course, in 9 ponies performing the Phase D of a national 3-day event championship (CIC*), and in 7 endurance horses participating at the European endurance championship 2005. White blood cells and granulocytes, total plasma proteins, creatine phosphokinase (CK), and total MPO contents were determined from blood samples. In addition, blood was taken from all ponies and 4 of the endurance horses 5 min after completion of the course to give some idea of the intensity of exercise. RESULTS: The mean blood lactate was 15.8 +/- 5.8 mmol/l after the CIC* and 2.7 +/- 0.2 mmol/l after the 160 km course. Performing both competitions induced a significant increase in CK and MPO. After the endurance course, the number of granulocytes significantly increased. Whilst there was no significant correlation between the measurements in CIC* ponies, MPO was significantly correlated with granulocyte count (r2 = 0.776) and CK (r2 = 0.586) in endurance horses. CONCLUSIONS: Intense exercise induces an activation of blood granulocytes, with degranulation of neutrophils and release of MPO. The plasmatic MPO concentration after endurance was higher than the values reported in some inflammatory pathological conditions. POTENTIAL RELEVANCE: This phenomenon may partly contribute to the occurrence of an exercise-induced oxidative stress and to the alteration of muscular membrane permeability. Further studies should be conducted to assess the possible relationship between MPO concentration and markers of oxidative stress in performance horses [less ▲]

The aim of this paper was to use a parametric stochastic frontier approach (coming from the economic literature) to explore the impact of the concept of activity (taken in a broad sense: i.e., including both professional and non-professional activities) on the constitution and the care of cognitive reserve among the European population aged 50 and up. For this purpose, we use individual data collected during the first wave of SHARE (Survey on Health, Ageing and Retirement in Europe) performed in 2004. The advantages of this survey were (1) it included a large population (n = 18,623) geographically distributed throughout Europe; and (2) it simultaneously analyzed several dimensions (physical and mental health, mobility, occupational activities, socioeconomic status, etc.). Our results confirm the positive impact of occupational activities on the cognitive functioning of elderly people. These results are discussed in terms of the prevention of cognitive aging and Alzheimer’s disease, and more particularly of retirement policy issues. [less ▲]

In this article, we’ll be wondering about the point, the challenges and the limits of integrating competences in Higher Education, starting from three experiences lead in Urban and Economic Geography. For this purpose, we’ve managed to combine works from Higher Education specialists and observations from the field. This reflection has been built in three stages. First, we’ll be reminding the foundations and specificities of the competence based approach. Then, we’ll be analysing our three experiences with the help of a common grid allowing us to successively consider the original needs and motivations, the process design, its trial and its adjustment. Finally, we’ll be trying to draw conclusion in terms of impacts on the students learning process, and impacts on the way teachers approach their teaching process, its limits and constraints.

When submitted to mercury porosimetry, some materials are penetrated by mercury whereas others, among the most porous, are densified by the isostatic pressure. Notably, this is the case for materials whose structure is made of particles aggregated into filament-like clusters that are interconnected in a 3-D array. Indeed, that kind of material undergoes a volume variation due to hierarchical pore collapse. In the case of intrusion, the mercury porosimetry data are classically analyzed by the Washburn equation. In the case of hierarchical pore collapse, data can be correctly analyzed by the collapse model equation. Using an equation that does not correspond to the mechanism leads to large errors in the pore size distribution. Thus, an accurate data analysis requires prior determination of the mechanism leading to the volume variation recorded as a function of the pressure. The present work particularly examines the complex and unusual behavior of partially pyrolyzed resorcinol-formaldehyde gels when submitted to mercury porosimetry. The unusual behavior encountered complicates the mechanism identification and, therefore, the equation selection. However, the major part of the volume distribution as a function of the pore size can be determined with a good accuracy. [less ▲]

The objective of this study was to evaluate the effects of GnRH administered at Day 12 post-AI on the reproductive performance of dairy cows. Holstein-Friesian dairy cows (n = 103) on a large Hungarian dairy farm were allocated randomly to treated (n = 54) or control (n = 49) groups. Twelve days after AI, treated cows received a GnRH agonist i.m., while the control group received a placebo (physiological saline). Progesterone radioimmunoassay was used to determine the correct timing of artificial insemination (Day 0) and the incidence of luteal insufficiency on Day 12. Ultrasonography and radioimmunoassay for pregnancy-associated glycoprotein were used to detect pregnancy and late embryonic/fetal mortality between Days 32 and 55 after AI. Three cows from each group were inseminated when progesterone concentrations were > 1.0 ng/mL, and six cows (four from the treated and two from the control group) had luteal insufficiency (progesterone < 1.0 ng/mL) on Day 12. Late embryonic/fetal mortality occurred in three treated cows and in two control cows. When these cows were removed from the model, calving rates after first service were 59.6% (28/47) and 59.1% (26/44) for treated and control cows, respectively (P > 0.05). There was no significant difference between treated and control cows when they were inseminated before or after Day 100 from calving. In summary, administration of a GnRH agonist on Day 12 after AI did not improve reproductive performance in dairy cows. However, our approach may be used for the field evaluation of different treatment protocols. (c) 2006 Elsevier Inc. All rights reserved. [less ▲]
