Status and perspectives of SARNET network

43 organisations (research, universities, industry, utilities, safety authorities and TSO) from 22 countries network their capabilities for R&D on Severe Accidents (SA) in SARNET (Severe Accident Research NETwork of excellence) in the EC FP7 for 4 years from April 2009. The overall work represents about 40 persons per year (230 researchers and 20 PhD students). A 43rd partner is currently joining the network: BARC (India). See www.sar-net.e

Proposed relation between SARNET network on severe accidents and TWG Gen.II/III

SA Research Priorities defined in SARNET network should be the basis for proposing in the future relevant R&D programs to address them, when needed, and launch projects with the endorsement of TWG

TERRISCOPE: AN OPTICAL REMOTE SENSING RESEARCH PLATFORM USING AIRCRAFT AND UAS FOR THE CHARACTERIZATION OF CONTINENTAL SURFACES

ONERA is developing TERRISCOPE, a new platform to characterize the environment and the continental surfaces by optical remote sensing using manned aircrafts and UAS (Unmanned Airborne System). The objective of TERRISCOPE is to make available to the scientific community combinations of optical measurements remotely sensed with the best level state-of-the-art sensors. Different kinds of sensors have already been acquired or are still being acquired: Hyperspectral sensors (0.5–2.5 μm range), visible high resolution cameras, multispectral infrared cameras and airborne laser scanners. Each sensor is declined in two versions: one high performance for manned aircrafts and one more compact for UAS. This paper describes the whole equipment, and presents the main characteristics and performances of the carriers, the sensors and the processing chain. Possible sensors combinations on airplanes and UAS are also presented, as well as preliminary results

Neo/adjuvant chemotherapy does not improve outcome in resected primary synovial sarcoma: a study of the French Sarcoma Group

Background: There are only scarce data about the benefit of adjunctive chemotherapy in patients with localized synovial sarcoma (SS). Patients and methods: Data from 237 SS patients recorded in the database of the French Sarcoma Group were retrospectively analyzed. The respective impact of radiotherapy, neo-adjuvant chemotherapy and adjuvant chemotherapy on overall survival (OS), local recurrence-free survival (LRFS) and distant recurrence-free survival (DRFS) were assessed after adjustment to prognostic factors. Results: The median follow-up was 58 months (range 1-321). Adjuvant, neo-adjuvant chemotherapy and postoperative radiotherapy were administered in 112, 45 and 181 cases, respectively. In all, 59% of patients treated with chemotherapy received an ifosfamide-containing regimen. The 5-year OS, LRFS and DRFS rates were 64.0%, 70% and 57%, respectively. On multivariate analysis, age >35 years old, grade 3 and not-R0 margins were highly significant independent predictors of worse OS. After adjustment to prognostic factors, radiotherapy significantly improved LRFS but not DRFS or OS. Neither neo-adjuvant nor adjuvant chemotherapy had significant impact on OS, LRFS or DRFS. Conclusion: As for other high-grade soft-tissue sarcomas, well-planned wide surgical excision with adjuvant radiotherapy remains the cornerstone of treatment for SS. Neo-adjuvant or adjuvant chemotherapy should not be delivered outside a clinical trial settin

Microbial dynamics in industrial blue veined cheeses in different packaging

International audienceThe aim of this study was to evaluate the effects of packaging on the microbiota of blue veined cheeses. The microbial dynamics of portions of industrial cheeses packaged under vacuum in different films and whole cheeses in aluminium foil was compared using culture-dependant and metagenomic approaches. There was no oxygen in the packaging and CO2 concentrations were between 5 and 12%. The composition of the lactic acid bacteria population did not change significantly during storage; it varied more according to factory of origin. Vacuum packaging hampered the growth of aerobic bacteria (Brevibacterium, Arthrobacter, Brachybacterium) and Gram-negative bacteria more than did stretch film. In vacuum-packed cheese portions, Staphylococcus and/or Brevibacterium and Arthrobacter were the dominant Gram-positive catalase-positive populations, depending on the factory of origin. Cheese packaged under vacuum had a lower pH than cheese in aluminium foil or stretch film

Changes in biochemical and sensory parameters in industrial blue-veined cheeses in different packaging

International audienceThe effects of packaging on the biochemical and sensory characteristics of industrial blue-veined cheese (pieces of cheeses pre-packaged in materials of different permeability and whole cheeses traditionally wrapped in aluminium foil) were evaluated over 43 days of storage. In cheese pieces in reduced-O-2 packaging, less ammonia production and lower proteolysis were observed. Packaged cheese pieces were distinguished from controls by higher levels of (a) methyl ketones and their corresponding alcohols and acids, (b) methyl acids derived from branched chain amino acids and (c) esters. This may be due to less oxidation. Packaged cheese pieces were also more acid, with more pungency, creaminess and milky odour and less bitterness than the control cheeses. They have high moisture content, owing to the low water vapour permeability of the films. Fourme d'Ambert cheese pieces wrapped in permeable film behaved similarly to the corresponding control throughout storage
