Avant-propos

La mer Noire, ancien segment maritime du Rideau de fer, connaît un regain d'intérêt depuis 1989. Amorçant une ouverture économique réciproque, onze pays se sont regroupés au sein de la Zone de Coopération Economique de la mer Noire (ZCEMN), créée en juin 1991 à l'initiative de la Turquie, avec l'objectif d'instaurer une zone de libre échange et d'établir de multiples connexions. Mais la Turquie cherche surtout à se rapprocher de la Communauté européenne. Son influence renouvelée sur un espace considérablement étendu répond au souci occidental de combler un vide stratégique sur les marges méridionales de l'ex-URSS. Cependant, cette puissance régionale ne dispose que de moyens limités. Enfin l'aire de la mer Noire, dépourvue d'unité politique, culturelle ou religieuse, rassemble des Etats impliqués dans des logiques de tension. La Grèce, membre à la fois de la ZCEMN et de la CEE, étant un interlocuteur incontournable, le règlement des contentieux gréco-turcs est un préalable à toute politique cohérente et coordonnée sur les marges sud-est de l'Europe

Preferences for long-term follow-up care in childhood cancer survivors

Follow-up care is important for childhood cancer survivors to facilitate early detection and treatment of late effects. We aimed to describe preferences for different organisational aspects and models of follow-up care among Swiss childhood cancer survivors, and characteristics associated with preferences for different models. We contacted 720 survivors aged 18+ years, diagnosed with cancer after 1990 (age 0-16 years), registered in the Swiss Childhood Cancer Registry (SCCR), and Swiss resident, who previously participated in a baseline survey. They received questionnaires to assess attendance and preferences for follow-up (rated on 4-point scales, 0-3). Clinical information was available from the SCCR. Survivors (n = 314: response rate 43.6%; 47.8% still attended follow-up) rated clinical reasons for follow-up higher than supportive reasons (p < .001). They rated checking for cancer recurrence (mean = 2.78, SD = 0.53) and knowing about risks for my children most important (mean = 2.22, SD = 0.83). They preferred to attend a children's hospital (mean = 1.94, SD = 1.11), adult hospital (mean = 1.86, SD = 0.98) or general practitioner (mean = 1.86, SD = 1.01) rather than a central specialised late effects clinic (mean = 1.25, SD = 1.06, p < .001), and be seen by paediatric (mean = 2.24, SD = 0.72) or medical oncologist (mean = 2.17, SD = 0.69). Survivors preferred decentralised clinic-based follow-up, rather than one central specialised late effects clinic. Survivors' preferences should be considered to ensure future attendance

Mutations des régions frontalières avec l’Union européenne: Cahiers du CEFRES N° 9f, Territoires en mutation

International audienceCette seconde table ronde a pour sujet les mutations des régions frontalières avec l’Union européenne. Tout d’abord, Michel Foucher (Université Lumière Lyon II) s’intéresse à la problématique sans cesse renouvelée des frontières internes et externes de l’Union européenne, puis G. Lepesant (CERI) se concentre sur les échanges et la coopération aux frontières orientales de l’Allemagne. Jiří Patočka (AV ČR) communique ensuite sur certains aspects du développement des eurorégions en République tchèque tandis que František Zich (UK) s’intéresse aux évolutions des relations entre les habitants des régions frontalières germano-tchèques. Suivent une communication de Giorgio Ficarelli (Comission européenne) sur les actions de soutien de l’Union européenne à la coopération transfrontalière, une autre de Jaroslav Zámečník qui se focalise sur une expérience particulière de coopération frontalière, celle de l’eurorégion Nisa, et une autre de Milan Jeřábek (Masarykova Univerzita), commentant les résultats de sondages réalisés dans les régions frontalières tchéco-allemandes. Enfin, Jiří Tomeš (UK) réfléchit à une problématisation de la différenciation régionale et de son contexte politique et Ľubomír Falťan (SAS) conclut sur quelques remarques au sujet des relations transfrontalières austro-slovaques

Effect of GA 3 and paclobutrazol on adventitious shoot regeneration of two Pelargonium sp

This study had two aims. The first was to improve the regeneration efficiency of Pelargonium leaf discs by adventitious budding. The second was to test the effect of gibberellic acid (GA 3) and paclobutrazol (PBZ) on callus formation and adventitious shoot regeneration in Pelargonium before using genetic transformation of this species for functional validation of genes involved in the process of GA regulation. GA 3 and paclobutrazol (an inhibitor of GA synthesis pathway) were added (together or separately) in the shoot regeneration media of two Pelargonium species, Pelargonium * hortorum \u27Panache sud\u27 (\u27P.sud\u27) and Pelargonium * domesticum \u27Autumn haze\u27 (\u27 P.dom\u27). In both cases, GA 3 applied alone, completely inhibited the bud regeneration. Moreover, the rate of callus formation decreased drastically when 5 M of GA 3 was applied to \u27 P. dom\u27 explants. Similar result was obtained with \u27P.sud\u27 explants using 20 M GA 3. Paclobutrazol (0.3 M) applied at the same time as GA 3 (10 M) could partially restore regeneration process of \u27 P. dom\u27. For \u27 P. dom\u27, the use of paclobutrazol alone increased callus formation and slightly improved the rate of regeneration. Moreover, initiated buds had a better appearance. For \u27P. sud\u27, which had an abundant callusing, paclobutrazol did not improve regeneration and led to hyperhydric shoots

X-ray diagnostics of dodecane jet in spray A conditions using the new one shot engine (NOSE)

[EN] Quantifying liquid mass distribution data in the dense near nozzle area to develop and optimize diesel spray by optical diagnostic is challenging. Optical methods, while providing valuable information, have intrinsic limitations due to the strong scattering of visible light at gas-liquid boundaries. Because of the high density of the droplets near the nozzle, most optical methods are ineffective in this area and prevent the acquisition of reliable quantitative data. X-ray diagnostics offer a solution to this issue, since the main interaction between the fuel and the X-rays is absorption, rather than scattering, thus X-ray technique offers an appealing alternative to optical techniques for studying fuel sprays. Over the last decade, x-ray radiography experiments have demonstrated the ability to perform quantitative measurements in complex sprays. In the present work, an X-ray technique based on X-ray absorption has been conducted to perform measurements in dodecane fuel spray injected from a single-hole nozzle at high injection pressure and high temperature. The working fluid has been doped with DPX 9 containing a Cerium additive, which acts as a contrast agent. The first step of this work was to address the effect of this dopant, which increases the sensitivity of X-ray diagnostics due its strong photon absorption, on the behavior and the physical characteristics of n-dodecane spray. Comparisons of the diffused back illumination images acquired from ndodecane spray with and without DPX 9 under similar operating conditions show several significant differences. The current data show clearly that the liquid penetration length is different when DPX 9 is mixed with dodecane. To address this problem, the dodecane was doped with a several quantities of DPX containing 25% ± 0.5 of Cerium. Experiments show that 1.25% of Ce doesn’t affect the behaviour of spray. Radiography and density measurements at ambient pressure and 60 bars are presented. Spray cone angle around 5° is obtained. The obtained data shows that the result is a compromise between the concentration of dopant for which the physical characteristics of the spray do not change and the visualization of the jet by X-ray for this concentration.This work is supported by ANR Research National Agency (ECN-France project).
