Quality of Life Assessment in Internal Medicine Patients

The relationship between quality of life and chronic illness is clearly established, the evaluation of the latter is necessary for overall care of these patients, the SF36 is a good tool dedicated to this purpose. Our study, although limited by its single-center nature, sheds light on the impact of pathologies encountered in internal medicine hospitalization on quality of life. Our series includes 41 patients with a slight female predominance: 22 women and 19 men. The average age is 48 years old. Thus, it appears that, just like cancer, diabetes and connective tissue disease significantly reduce the quality of life of patients

Synthesis, spectroscopic and electrochemical properties of new covalent assemblies between TTF and various acceptors

Five new acceptor-π–TTF-π-acceptor (A–D–A) triads that contain pyridine, quinoline, nitrophenyl or nitrofuryl groups as acceptor unit have been synthesized by two-fold Wittig olefination reactions and their electrochemical behavior has been studied by cyclic voltammetry (CV). The intramolecular charge transfer (ICT) band in these molecules was characterized by UV–visible electronic absorption spectroscopy and these studies were completed by DFT calculations in the gas phase. These materials appear to be good candidates for the preparation of electroactive discrete metal complexes or coordination polymers as well as for the preparation of radical cations salts

Influence of surface morphology on erosion of plasma-facing components in H-mode plasmas of ASDEX Upgrade

Net erosion of plasma-facing materials was investigated at the low-field-side (outer) strike-point area of the ASDEX Upgrade (AUG) divertor during H-mode discharges with small and frequent ELMs. To this end, Au and Mo marker samples with different surface morphologies and geometries were exposed to plasmas using the DIMII divertor manipulator. The results were compared to existing erosion and deposition patterns from various Land H-mode experiments, in the latter case the main difference was the size and frequency of the ELMs. We noticed that increasing surface roughness reduces net erosion but less than what is the case in L-mode. On the other hand, net-erosion rates in H-mode are generally 2–5 times higher than the corresponding L-mode values, in addition to which exposure in H-mode conditions results in strong local variations in the poloidal and toroidal erosion/deposition profiles. The latter observation we associate with the large migration length, on the order of several cm, of the eroded material, resulting in strong competition between erosion and re-deposition processes especially at poloidal distances > 50 mm from the strike point. Considerable net erosion was measured throughout the analysed poloidal region unlike in L-mode where the main erosion peak occurs in the vicinity of the strike point. We attribute this qualitative difference to the slow decay lengths of the plasma flux and electron temperature in the applied H-mode scenario. Both erosion and deposition require detailed analyses at the microscopic scale and the deposition patterns may be drastically different for heavy and light impurities. Generally, the rougher the surface the more material will accumulate on locally shadowed regions behind protruding surface features. However, rough surfaces also exhibit more non-uniformities in the quality or even integrity of marker coatings produced on them, thus complicating the analyses of the experimental data. We conclude that local plasma parameters have a huge impact on the PFC erosion rates and, besides incident plasma flux, surface morphology and its temporal evolution have to be taken into account for quantitative estimates of erosion rates and PFC lifetime under reactor-relevant conditions

Étude géophysique du site du barrage d’Oum Laksab (Tunisie Centre-Ouest)

Pour mieux concevoir les ouvrages d’exploitation d’eau et les orienter vers les sites les plus favorables, la caractérisation de la structure géologique et géométrique tridimensionnelle demeure importante, nécessitant l’utilisation d’outils de reconnaissance très élaborés.La connaissance géophysique du site du barrage souterrain d’oued Oum Laksab s’est basée sur l’application des méthodes géophysiques (électrique et sismique réfraction). Elle est effectuée dans le lit de l’oued afin d’étudier les variations lithologiques et définir le cadre géotechnique. En effet, les horizons géoélectriques et géosismiques mis en évidence montrent l’existence d’un niveau conducteur qui pourrait correspondre à des argiles. Cette série d’une dizaine de mètres d’épaisseur pourrait servir comme un écran souterrain imperméable efficace

Synthesis of new hydroxylated mono and bis-tetrathiafulvalenes: Electrochemical behaviour, X-ray analysis and conductivity

International audienceSeries of unsymetrical and judiciously functionnalized tetrathiafulvalenes (TTFs) are elaborated by the protection-deprotection of thiolates or selenolates strategy. We have connected the physical properties of the corresponding materials to the interactions born out of the presence of selenium atoms on one side or both sides of the TTF core. The electrochemical values of the new donors are presented. Radical cation salts (RCS) and charge transfer complexes (CTC) were prepared in order to study, in particular, their electrical conductivit
