Neurophysiological testing has become a valuable tool for investigating brain excitability and nociceptive systems in headache disorders. Previous reviews have suggested that most neurophysiological tests have limited value for headache diagnosis, but a vast potential for exploring the pathophysiology of headaches, the central effects of certain pharmacological treatments and phenotype-genotype correlations. Many protocols, however, lack standardization. This meta-analytical review of neurophysiological methods in migraine was initiated by a task force within the EUROHEAD project (EU Strep LSHM-CT-2004-5044837-Workpackage 9). Most of the neurophysiological approaches that have been used in headache patients are reviewed, i.e. evoked potentials, nociception-specific blink reflex, single-fibre electromyography, neuroimaging methods (functional MRI, PET, and voxel-based morphometry) and the nitroglycerin attack-provoking test. For each of them, we summarize the results, analyse the methodological limitations and propose recommendations for improved methodology and standardization of research protocols. The first part is devoted to electrophysiological methods, the second to neuroimaging techniques and the NTG test. [less ▲]

Neuroimaging methods have been widely used in headache and migraine research. They have provided invaluable information on brain perfusion, metabolism and structure during and outside of migraine attacks, contributing to an improved understanding of the pathophysiology of the disorder. Human models of migraine attacks are indispensable tools in pathophysiological and therapeutic research. This review of neuroimaging methods and the attack-provoking nitroglycerin test is part an initiative by a task force within the EUROHEAD project (EU Strep LSHM-CT-2004-5044837-Workpackage 9) with the objective of critically evaluating neurophysiological tests used in migraine. The first part, presented in a companion paper, is devoted to electrophysiological methods, this second part to neuroimaging methods such as functional magnetic resonance imaging, positron emission tomography and voxel-based morphometry, as well as the nitroglycerin test. For each of these methods, we summarize the results, analyse the methodological limitations and propose recommendations for improved methodology and standardization of research protocols. [less ▲]

In the beginning of a project where repair, protection or reinforcement works are planed on industrial floors, the condition of the structure must be inspected and assessed properly. Which kind of expertise and qualifications are expected from the assessment consultant, depends on the structure, its environment and potential defects. The investigation must be thorough enough to get a reliable picture over the existence, extent, grade, reasons and effects of all significant degradation mechanisms and to assess their progress and effect on the essential requirements that the structure shall meet. The aim of this chapter is to present the general procedures to be followed in order to investigate the common situation of the industrial floors. As the testing procedures are very similar as well for concrete substrate than for overlay evaluation, the principles of the measurement are given hereafter, while the specific applications will be described in chapters 4.2., 4.3. and 4.4. Engineers generally require guidance on both the techniques available for the condition assessment of structures and the methods for data interpretation. Two major stages are usually recommended for such operation. The first stage is based on a rapid-scan visual assessment, often including limited sampling in areas obviously damaged, from which areas can be selected for more detailed investigations. The second stage contains detailed diagnostic survey relies on destructive and non destructive testing techniques. [less ▲]

Coastal aquifers are under a continuous threat of pollution due to the danger of sea water intrusion. In many cases, this threat has become a reality, as a result of excessive pumping beyond some safe yield. Israeli coastal aquifer is a good example. In some places around the world, existing wells, especially close to the coast, have to be abandoned, and the available fresh water of the coastal aquifer decreases. Also, the area above the intruding sea water wedge is lost as a source of water by natural recharge or natural replenishment. Artificial recharge may constitute a response against seawater intrusion. Because of over exploitation of pumping wells, hydraulic depressions appeared along the coast and seawater intrusion advanced inland. The topic of the thesis merges two methodologies linked to these problems. The first one aims the evaluation of different artificial recharge scenarii for controlling sea water intrusion in the Israeli coastal aquifer. Thus, two sites have been selected to apply the first methodology, namely Tel Aviv/Yafo city and Ashqelon town. Secondly, it concerns a new method to assess the vulnerability of pumping/injection wells facing with sea water intrusion and finally for ranking the different mentioned artificial recharge scenarii. The first of both of them is applied with the use of VASP and FEAS software including the existing model of the Israeli coastal aquifer and the second includes the DPSIR concept. VASP is a piece of software for the generation and post-processing of models in addition to the analysis and visualization of environmental data. FEAS is a piece of software that is based on the finite elements techniques, developed for simulating sea water intrusion in two- and three-dimensional coastal aquifers, and upconing problems. The second approach has been developed in prospect to be applied later once the necessary tools would be available. [less ▲]

The intensified cultivation of the rice crop constitutes an important challenge for Gabon in its strategy for food security of the populations. For this purpose, six NERICA rice varieties were selected by farmers from the PVS (Participatory Varietal Selection) trials that were conducted MASUKU in High-Ogooué sine 2009. The agromorphological characteristics like tillering and plant height and yield components (number of panicles/m2, number of grains/panicle, 1000 grain weight, sterility rate) were tested during the vegetative phase. The results were exciting. The six new varieties revealed the following good characteristics: - a good aptitude for high tillering (more than 350 tillers per m2 ); - a good height (more than 120 cm per plant); - a high number of panicles per m2(more than 220 panicles per m2); - the good weight of 1000 grains (more than 25 g). In general, the yield per hectare was very good varying between 4200 kg/ha for NERICA 11 and 7150 kg/ha for the NERICA 14. Consequently, the six newNERICA rice varieties are well adapted to the agroecological conditions of MASUKU and can be diffused in the rice plains of the locality. [less ▲]

The essential role of the thymus is to install an extremely diverse repertoire of T lymphocytes that are self-tolerant and competent against non-self, as well as to generate self-antigen specific regulatory T cells (Treg) able to inactivate in periphery self-reactive T cells having escaped the thymic censorship. Although indirect, techniques of medical imaging and phenotyping of peripheral T cells may help in the investigation of thymic function. Nowadays however, thymopoiesis is better evaluated through quantification by PCR of T-cell receptor excision circles (TREC) generated by intrathymic random recombination of the gene segments coding for the variable parts of the T-cell receptor for antigen (TCR). The TREC methodology is very valuable in the circumstances not associated with intense proliferation or apoptosis of peripheral T lymphocytes. [less ▲]

Les modalités de suivi qui y sont proposées ont pour objet d'informer les apprenants sur leur niveau d'expertise. Elles se centrent non seulement sur les performances, mais également sur la manière dont les apprenants mobilisent et combinent leurs connaissances et leurs expériences pour analyser leur réalité professionnelle. Dans notre intervention, nous illustrerons les indicateurs choisis pour évaluer le niveau de compétence de l'apprenant et les feedbacks communiqués pour progresser. [less ▲]
