We have obtained high-precision measurements of Vega at projected baselines between 103 m and 273 m with the CHARA Array using the (FLUOR) beam combiner in the K' band. A strongly gravity-darkened model atmosphere is in general agreement with both our interferometric data and archival spectrophotometry. This model indicates that Vega is rotating at 91%ofitsangular break-uprateandthatthepole-to-equator effectivetemperaturedifference is 2250 K. [less ▲]

IR (1-20 micron) observations, photometry, and narrow band spectrophotometry of SN 1987A obtained between March 16 and October 12, 1987, are presented. Variations of the bolometric luminosity are determined from IR and optical photometry. The spectral energy distribution, effective radius, and effective temperature of the hotter component are derived. Also, observations of hydrogen lines and CO emission are discussed. [less ▲]

The results of the first 4 mo of the ESO La Silla IR photometric monitoring program of SN 1987A. IR light curves are presented, and the IR data are combined with optical photometry to determine the luminosity, the effective radius, and the effective temperature, and how they evolved. Particular attention is given to the IR excess which become apparent beginning less than 1 mo after the explosion. Three possible interpretations of the excess IR emission are presented: an IR echo from preexisting dust, thermal emission from dust that has just condensed from the ejecta, and free-free emission from the expanding ejecta. None of the models are entirely satisfactory. [less ▲]

The thread imposed upon the earth"s atmosphere by anthropogenic activities is becoming well documented. Analyses of infrared solar observations carried out at the International Scientific Station of the Jungfraujoch, Switzerland, in 1950-51 and more intensively since the late 1970s have contributed to that documentation. This paper summarizes original findings arrived at so far and raises the need for intensive and coordinated observational programs during the 1990s. [less ▲]

DNA oligonucleotide ions forming G-quadruplex structures were studied in the gas phase using IRMPD spectroscopy. Data interpretation on these large biomolecule ions was made using carefully chosen control experiments. The major finding is a fingerprint of hydrogen bonding in the gas phase in the guanine C6=O6 stretching mode, that allows probing the conservation of G-quartets in the gas phase. The experiments demonstrate the conservation of G-quadruplex hydrogen bonds in the human telomeric sequence d(TTAGGG)4. [less ▲]

The unresolved v3 band Q branch of sulfur hexafluoride, SF6, at 947.9 cm-1 has been identified and quantitatively analyzed in series of high-quality infrared solar spectra recorded at the International Scientific Station of the Jungfraujoch, Switzerland, and at the National Solar Observatory facility on Kitt Peak in Arizona. Series of monthly mean total vertical column abundances of SF6 above both stations, deduced from that feature with line-by-line nonlinear least squares fitting methods, are reported over the time intervals from June 1986 to June 1990 for the Jungfraujoch and from March 1981 to June 1990 for Kitt Peak. Assuming an exponential growth model for fitting these series of measurements, it is found that the vertical column abundances have increased at mean rates of 6.9 +- 2.8 %/yr above the Jungfraujoch (calculated columns of 2.99 x 10E13 molecules/cm2 in June 1986 and 3 94 x 10E13 molecules/cm2 in June 1990) and 6.6 +- 7.2 %/yr above Kitt Peak (calculated columns equal to 2.97 x 10E13 molecules/cm2 in June 1981 and 5.38 x 10E13 molecules/cm2 in June 1990), the uncertainties corresponding to 2 sigma confidence levels. These results are further discussed within the context of variability and compared with previously published measurements. [less ▲]

This paper surveys the growing literature on developing countries’ infrastructure performance measured through frontier analysis techniques. The focus is generally on assessments of operators’ efficiency and productivity growth as part of benchmarking exercises. Two broad types of benchmarks are identified in the literature. The first is based on cross-country or cross regional performance comparisons, the second compares performance before and after reforms, including privatization. These benchmarks are often used to assess the impact of potential or actual policy reforms in specific countries. In a growing number of instances, they are also being conducted in the context of tariff revisions to assess the efficiency gains that can be shared with users as part of these revisions. The main policy conclusions are that there is a difference in the performance effect of key reforms, in particular privatization, between the transport sector and the utilities sector but that generally incentive based regulation delivers efficiency in both sectors The main technical conclusion is that even if in developing economies data problems are constraining, these constraints are not as binding as often argued.

The paper investigates the potential of using widgets-based reflection amplifiers in e-learning courses. Reflection amplifiers are structured opportunities for students to examine and evaluate aspects of their learning experience. The paper deliberately chooses a non-technical viewpoint. It takes the teachers' voices as a starting point. The study reports the results of a survey that asked open educational resources (OERs) course creators about their opinions on different types of reflection amplifiers. The outcomes demonstrate that several reflection techniques are recognised and acknowledged by these practitioners as being of relevance for their courses. Yet, practical application in their courses is quite rare. Results of the survey are subsequently used to inspect possible contributions of widgets technology to the implementation and dissemination of a selection of reflection techniques. The set-up of an experiment intended to test feasibility and relevance of widgets-based reflection amplifiers is eventually outlined. [less ▲]

MSC cells have demonstrated significant immunosuppressive effects in various in vivo and in vitro studies. This study aims to be the first evaluation of the safety and tolerability of third party MSC infusion after cadaveric kidney and liver transplantation in a prospective phase I-II study, taking advantage of our centre expertise and experience in MSC use in graft-versus-host disease (GVHD) after bone marrow transplantation and using an already functioning GMP-compliant laboratory producing clinical-grade MSC. Secondary end-points will help to evaluate the immunosuppressive potential of MSC after organ transplantation, and the opportunity to develop larger randomised, controlled, phase III trials. After successful transplantation, 10 liver and 10 kidney transplant recipients under standard immunosuppression (tacrolimus, MMF, steroids) will receive an intravenous infusion of 1.5-3x106/kg of third-party MSC on post-operative day 3±2. These patients will be prospectively compared to 10 liver and 10 kidney recipients who meet the inclusion criteria but deny MSC infusion. Safety will be assessed by recording side effects, including opportunistic infections and cancers. Immunosuppressive potential will be evaluated by rejection episode rates, by graft/patient survivals, by immunohistology of 3-months kidney and 6-month liver graft biopsies and by in vitro evaluation of the immunity profile of the recipients. In a second step, reduction (kidney) and progressive weaning (liver) of immunosuppression will be attempted in recipients who received MSC. This ongoing study is supported by research grants from the CHU of Liège, University of Liège, and by the Senior Clinical Research Grant from ESOT. The first patients were included and treated in early 2012, and final results expected in late 2013. [less ▲]
