This paper presents the reframing approach developed by Michel Monroy. His approach deals more particularly with the reframing of conflictual situations experienced within the frame of a family as well as at work. The way he gives shape to his practice seems to us to be an interesting contribution on the field of methodology as well as to the reframing technique as such. [less ▲]

Materials exhibiting a strong piezoelectric effect may be used in many applications, where they serve as sensors, actuators or transducers. These applications range from for sub-millimeter length scales in MEMs (Micro-Electro-Mechanical Systems) up to large scales in the the design of smart wings in the aerospace industry. As for regular materials subjected to high mechanical stresses, the knowledge of fracture behavior for these smart materials is often crucial within the design of parts under high electrical and mechanical loading. The Extended Finite Element Method [1] has been originally designed for crack growth analysis in isotropic elastic materials. In association with level-sets [2] as a mean for representing the crack geometry, it is a powerful way to get rid of the costly constrained remeshing needed with conventional techniques. Under certain circumstances, this method is also able to achieve regular convergence rates in the energy error even for a cracked domain [3]. Piezoelectric materials exhibit an transversely isotropic mechanical characteristic, as well as a coupling between mechanical and electrical variables. This leads to different near-crack tip mechanical fields and the presence of singularities in the electrical variables [4][5]. To treat this new problem in the X-FEM, specific crack analysis tools and changes in the enrichment functions are needed which allows to represent the crack- both in the mechanical and electrical functional spaces. In this work, we will present these techniques and perform a convergence analysis to ensure that the crack tip behavior is accurately taken into account. Finally, we suggest a simple propagation model for crack growth. [less ▲]

The book explains the physical foundations of the most common in-vivo medical imaging modalities. It is written for readers having a basic knowledge of physics. However the most essential physical phenomenon and their properties are described. Exploring the electromagnetic spectrum from the shortest to the longest wavelengths the book deals with nuclear imaging, RX imaging, endoscopy, thermography and MRI. Acoustic wave and ultrasonography is the next subject. The book ends with the digital image and a few radioprotection notions. [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 ▲]

Using manual acoustic tracking our study quantified (1) the spatial distribution (2) the movement patterns and (3) the depth preference of adult whitefish, Coregonus lavaretus in it small artificial lake of eastern Belgium were the species was introduced in 1978 for recreational fishing. From June to October 2004, n=6 C. lavaretus (LF 285-519 mm) were tracked (pingers and depth sensor transmitters) from a small boat over periods ranging from 98 to 108 days in Robertville Lake (elevation: 490 m; area: 63 ha max. depth: 47 in). Whitefish were consistently mobile but showed quite variable lake use patterns. Two individuals traveled the entire length and breadth of the lake, whereas others remained in movement in the deep zone in the middle part of the lake or near the retaining darn wall. Whitefish occupied positions in the water column ranging front 2.6 to 27.0 m (mean 12.7 +/- 5.6 m) that varied depending on individuals. This first study on individual whitefish behaviour provides a better understanding of the behavioural ecology of the species in small artificial lake. [less ▲]

A new automate, ImmunoCap 250 has recently been released by Sweden Diagnostics for the determination of specific and total IgE. We have evaluated its analytical performances (intra- and inter-assay precision, linearity, recovery and sensibility) and compared the results obtained by Unicap 100 on 149 samples positive for 12 different allergens and 30 samples containing different concentrations of total IgE. Intra- and inter-assay precision are less than 10% excepted for the specific IgE of one allergen (i3, common wasp), but still in accordance with the NCCLS guidelines. The sensibility is 0.01 kU(A)/L for specific and 0.35 kU/L for total IgE. The method is linear up to 5000 kU/L for total and at least 80 kU(A)/L for specific IgE. The recovery test showed a recovery of the International standard WHO 75/502 between 85 and 115%, with a mean of 103%. The correlation coefficient between the ImmunoCap 250 and Unicap 100 is 0.9866 and 0.9984 for specific and total IgE respectively. ImmunoCap 250 is a good solution for laboratories that perform twenty to thirty thousand determinations. [less ▲]

The rabbit is an essential model in scientific research, particularly in the study of cardiovascular diseases such as hypertension and atherosclerosis and for the investigation of the osteoarticular system. Due to the fact that various factors (environmental, microbial, stress, pain.) can influence data obtained from experiments, special care must be given to housing conditions. Sensory enrichment (olfactive, auditive, visual or tactile stimuli) and physical enrichment (nutritional and social stimuli) allow rabbits to express specific behaviours and reduce stereotypies. This synthesis reminds of the importance of these factors and gives to the researcher some ways to control them. [less ▲]
