BACKGROUND: Organ procurement and transplant activity from controlled donation after circulatory death (DCD) was evaluated over an 11-year period to determine whether this program influenced the transplant and donation after brain death (DBD) activities. MATERIAL AND METHODS: Deceased donor (DD) procurement and transplant data were prospectively collected in a local database for retrospective review. RESULTS: There was an increasing trend in the potential and actual DCD numbers over time. DCD accounted for 21.9% of the DD pool over 11 years, representing 23.7% and 24.2% of the DD kidney and liver pool, respectively. The DBD retrieval and transplant activity increased during the same time period. Mean conversion rate turning potential into effective DCD donors was 47.3%. Mean DCD donor age was 54.6 years (range, 3-83). Donors >/=60 years old made up 44.1% of the DCD pool. Among referred donors, reasons for nondonation were medical contraindications (33.7%) and family refusals (19%). Mean organ yield per DCD donor was 2.3 organs. Mean total procurement warm ischemia time was 19.5 minutes (range, 6-39). In 2012, 17 DCD and 37 DBD procurements were performed in the Liege region, which has slightly >1 million inhabitants. CONCLUSIONS: This DCD program implementation enlarged the DD pool and did not compromise the development of DBD programs. The potential DCD pool might be underused and seems to be a valuable organ donor source. [less ▲]

La qualité des services d'accueil et d'éducation des jeunes enfants constitue un enjeu sociétal d'actualité, mais peut faire l'objet d'interprétations multiples. Fondé sur les résultats d'une recherche menée dans une démarche de théorisation ancrée, cet article donne de manière synthétique une grille de lecture de différentes manières de considérer la qualité des services d'accueil et d'éducation des jeunes enfants dans un cadre professionnel.

The first part of this article [1] described the methodology to follow to develop a technique for the quantitative analysis of active substance in a solid tablet type formulation using near infrared spectroscopy. It seems appropriate to complete this description by detailing the different steps involved through illustrated examples and by proposing useful guidelines for new users. The quantitative analysis example chosen is that of content uniformity (CU) of tablet type solid forms (cf. Ph. Eur. 2.9.6/2.9.40) [2], a test required in the pharmaceutical industry and for which this alternative quantitative analysis could offer substantial gains. It should be noted that the approach described applies to other types of quantitative analysis (mean assay, water content in raw materials, polymorph assay within a tablet, etc.). [less ▲]

INTRODUCTION: Controlled donation after circulatory death (DCD) remains ethically controversial. The authors developed a controlled DCD protocol in which comfort therapy is regularly used. The aim of this study was to determine whether this policy shortens the DCD donors' life. METHODS: The authors retrospectively analyzed prospectively collected data on patients proposed for DCD at the University Hospital of Liege, Belgium, over a 56-month period. The survival duration of these patients, defined as duration between the time of proposal for DCD and the time of circulatory arrest, was compared between patients who actually donated organs and those who did not. RESULTS: About 128 patients were considered for controlled DCD and 54 (43%) became donors. Among the 74 non-donor patients, 34 (46%) objected to organ donation, 38 patients (51%) were denied by the transplant team for various medical reasons, and two potential DCD donors did not undergo procurement due to logistical and organizational reasons. The survival durations were similar in the DCD donor and non-donor groups. No non-donor patient survived. CONCLUSIONS: Survival of DCD donors is not shortened when compared with non-donor patients. These data support the ethical and respectful approach to potential DCD donors in the authors' center, including regular comfort therapy. [less ▲]

This working paper describes an experimental study carried out on a refrigeration scroll compressor with and without vapour injection. The test rig designed for that purposed allows evaluating the performance over a wide range of operating conditions, by varying the supply pressure, the injection pressure, the exhaust pressure, the supply superheating and the injection superheating. 97 Steady-state points are measured, with a maximum isentropic efficiency of 64.1% and a maximum consumed electrical power of 13.1 kW. A critical analysis of the experimental results is then carried out to evaluate the quality of the data using a machine learning method. This method based on Gaussian Processes regression, is used to build a statistical operating map of the compressor as a function of the different inputs. This statistical operating map can then be compared to the experimental data points to evaluate their accuracy. [less ▲]

While 3D cinema is becoming increasingly established, little effort has focused on the general problem of producing a 3D sound scene spatially coherent with the visual content of a stereoscopic-3D (s-3D) movie. The perceptual relevance of such spatial audiovisual coherence is of significant interest. In this paper, a subjective experiment is carried out where an angular error between an s-3D video and a spatially accurate sound reproduced through Wave Field Synthesis (WFS) is simulated. The psychometric curve is measured with the method of constant stimuli, and the threshold for bimodal integration is estimated. The impact of the presence of background noise is also investigated. A comparison is made between the case without any background noise and the case with an SNR of 4 dB(A). Estimates of the thresholds and the slopes, as well as their confidence intervals, are obtained for each level of background noise. When background noise was present, the point of subjective equality (PSE) was higher (19.4° instead of 18.3°) and the slope was steeper (-0.077 instead of -0.062 per degree). Because of the overlap between the confidence intervals, however, it was not possible to statistically differentiate between the two levels of noise. The implications for the sound reproduction in a cinema theater are discussed. [less ▲]

PSII antenna size heterogeneity has been intensively studied in the past. Based on DCMU fluorescence rise kinetics, multiple types of photosystems with different properties were described. However, due to the complexity of fluorescence signal analysis, multiple questions remain unanswered. The number of different types of PSII is still debated as well as their degree of connectivity. In Chlamydomonas reinhardtii we found that PSIIα possesses a high degree of connectivity and an antenna 2-3 times larger than PSIIβ, as described previously. We also found some connectivity for PSIIβ in contrast with the majority of previous studies. This is in agreement with biochemical studies which describe PSII mega-, super- and core- complexes in Chlamydomonas. In these studies, the smallest unit of PSII in vivo would be a dimer of two core complexes hence allowing connectivity. We discuss the possible relationships between PSIIα and PSIIβ and the PSII mega-, super- and core- complexes. We also showed that strain and medium dependent variations in the half-time of the fluorescence rise can be explained by variations in the proportions of PSIIα and PSIIβ. When analyzing the state transition process in vivo, we found that this process induces an inter-conversion of PSIIα and PSIIβ. During a transition from state 2 to state 1, DCMU fluorescence rise kinetics are satisfactorily fitted by considering two PSII populations with constant kinetic parameters. We discuss our findings about PSII heterogeneity during state transitions in relation with recent results on the remodeling of the pigment-protein PSII architecture during this process. [less ▲]

A l’heure de l’attribution des premières forêts communautaires au Gabon, de multiples questions surgissent et attendent de manière urgente une réponse de la part de l’Etat. Le présent article se penche sur l’une d’entre elles, à savoir la superposition des permis d’exploitation (minier, forestier) avec l’espace utilisé traditionnellement par les communautés locales et candidates à l’obtention d’une forêt communautaire. Quelques situations rencontrées sur le terrain sont présentées et discutées. Il est urgent qu’un réel aménagement du territoire voie le jour au Gabon, qui détermine la place de chaque activité, hiérarchise l’affectation de l’espace et détermine le cas échéant les conditions de « cohabitation » de plusieurs permis.
