The collinear eZe configuration of helium, with the electrons on opposite sides of the nucleus, is studied in the presence of an external electromagnetic (laser or microwave) field. We show that the classically unstable "asymmetric stretch" orbit, on which doubly excited intrashell states of helium with maximum interelectronic angle are anchored, can be stabilized by means of a resonant driving where the frequency of the electromagnetic field equals the frequency of Kepler-like oscillations along the orbit. A static magnetic field, oriented parallel to the oscillating electric field of the driving, can be used to enforce the stability of the configuration with respect to deviations from collinearity. Quantum Floquet calculations within a collinear model of the driven two-electron atom reveal the existence of nondispersive wave packets localized on the stabilized asymmetric stretch orbit, for double excitations corresponding to principal quantum numbers of the order of Ngreater than or similar to10.

Coatings are designed to protect concrete against environmental aggression. Water is one of the aggressive parameters able to deteriorate the concrete structure. The objectives of this paper are to present the effects of water (i) during application of coating on the concrete substrate and (ii) pull-off test. Semi-permanent moisty state produced by absorption from the uncoated face, total immersion or diffusion of water from the back face of the substrate are analysed. Water vapour diffusion and influence of hydrophobic treatment are also investigated. A classification based on increasing influence of the tests and application conditions on adhesion is proposed and clearly points out the negative effect of capillary action from the uncoated face.

This chapter reports the characteristics of a post graduate diploma on educational technologies based on a combination of face-to-face and distance activities and assesses its quality. We first define the bases of the training program and present several tools (logbook, portfolio and questionnaires) which have been used to evaluate and regulate both training and individual learning process. Our observations indicate an increase and better regulation of the quality of the educational and learning processes. On the basis of the results we achieved, we propose that our original design could be extended to similar adult training programs. The way this innovative system is integrated in the universities shows an evolution due to its success that implies a certain kind of return on investment due to the demand of such kinds of device.

Étant donné la place exceptionnelle dont elle jouit dans l'imaginaire collectif occidental depuis près de 4.000 ans, l'Égypte pharaonique est de nos jours l'objet de nombreuses idées reçues, qui, pour la plupart, remontent à l'Antiquité. L'examen que l'ouvrage propose des principales idées reçues générées par notre société à propos de l'Égypte antique vise à constituer un éveil autant à l'Égyptologie, à l'étude de ce que fut réellement la civilisation pharaonique, qu'à la manière dont celle-ci fut récupérée, exploitée et parfois déformée par notre système culturel, à ce que l'on appelle en Histoire la réception culturelle de l'Égypte.

The present review aims at presenting different methods for pregnancy diagnosis. Since these methods are to be used in the herds, precocity, sensitivity, specificity, accuracy to predict pregnant and non-pregnant ewes, and the possibility to determine fetal numbers are carefully analysed. The progesterone assay is accurate as early as day 17th after fecundation; but the fertilization day must be precisely known. The pregnancy specific or associated glycoproteins (PSPB/PAG) assay is highly sensitive and specific at day 22 in blood and at day 32 in milk samples. However, this assay does not allow to predict the fetal number. The ultrasonography B-mode used on 30 days of gestation gives very good or excellent performance in terms of sensitivity and specificity depending on the practitioner. The method is also able to predict the real time fetal number. [less ▲]

An on going project whose goal is the development and identification of a mathematical model of steel at elevated temperature using a mesoscopic approach is presented. The research aims to study the damage process at elevated temperature using information from the macroscopic and mesoscopic scales. As a final application our results will be used to study the industrial process of continuous casting of low carbon steel. [less ▲]

Relapsing varicella may occur in children with HIV infection and more rarely in younger adults. Our aim was to report unusual clinical, histologic, and virologic aspects of 4 elderly patients with malignant hemopathies who had an unusual form of recurrent varicella develop. Conventional microscopy, immunohistochemistry, and in situ hybridization were applied to smears and skin biopsy specimens. The patients presented a few dozen, scattered, large, papulovesicular lesions with central crusting. No zoster-associated pain or dermatomal distribution of the lesions was noted. Conventional microscopy revealed vascular changes and epidermal alterations typical for alpha-herpes virus infection. The varicella zoster virus major viral envelope glycoproteins gE and gB, and the immediate-early varicella zoster virus IE63 protein and the corresponding genome sequence for gE were detected on Tzanck smears; they were localized in endothelial cells and keratinocytes on skin biopsy specimens. The varicella zoster virus infection in endothelial cells, the vascular involvement, and the widespread distribution of the lesions suggest that the reported eruptions are vascular rather than neural in origin. These findings invalidate the diagnosis of herpes zoster but strongly support the diagnosis of recurrent varicella in an indolent and yet unreported presentation. Furthermore, these eruptions differ from relapsing varicella in children and young adults by the age of the patients, the paucity of clinical lesions, the larger diameter of the lesions and their peculiar clinical aspect, the significantly longer time interval between primary varicella and the recurrence, the prolonged healing time of the lesions, their mild disease course, and the fact that all the lesions are in the same stage of development.

We investigate the feasibility of CD34-selected peripheral blood stem cell (PBSC) transplantation followed by pre-emptive CD8-depleted donor lymphocyte infusions (DLI) after a minimal conditioning regimen. Six patients with advanced hematological malignancies ineligible for a conventional myeloablative transplant (n=5) or metastatic renal cell carcinoma (n=1), and with an HLA-identical (n=4) or alternative (n=2) donor were included. The nonmyeloablative conditioning regimen consisted in 2 Gy TBI alone (n=4), 2 Gy TBI and fludarabine (RCC patient, n=1) or cyclophosphamide and fludarabine (patient who had previously received 12 Gy TBI, n=1). Post transplant immunosuppression was carried out with cyclosporin (CyA) and mycophenolate mofetil (MMF). Initial engraftment was achieved in all patients. One out of six patients (17%) experienced grade > or =2 acute GVHD only after abrupt cyclosporin discontinuation and alpha interferon therapy for life-threatening tumor progression. T-cell chimerism was 23% (19-30) on day 28, 32% (10-35) on day 100, 78% (49-95) on day 180 and 99.5% (99-100) on day 365. Three out of four patients who had measurable disease before the transplant experienced a complete response. We conclude that CD34-selected NMSCT followed by CD8-depleted DLI is feasible and preserves engraftment and apparently also the graft-versus-leukemia (GVL) effect. Further studies are needed to confirm this encouraging preliminary report. [less ▲]

During the preliminary phase A of the Ground-based European Nulling Interferometer Experiment (GENIE), a number of interferometric configurations have been studied, in the cases of exozodiacal cloud and hot Jupiter detection. Their expected performances have been computed in light of the measured or expected performances of the VLTI sub-systems. A simple Bracewell nulling interferometer, formed of two Unit Telescopes and working in the L' or N bands, has been identified as a good candidate configuration for exozodiacal cloud detection. External or internal chopping, fringe tracking and intensity matching will be critical issues for this configuration. In the case of hot Jupiter detection, a double Bracewell with internal modulation in the L' band seems well appropriate, and should allow to carry out low resolution spectroscopy on a few bright exoplanets. The basic assumptions and computations which have lead to these candidate configurations are described in this paper. [less ▲]
