The XXL Survey V: Detection of the Sunyaev-Zel'dovich effect of the Redshift 1.9 Galaxy Cluster XLSSU J021744.1-034536 with CARMA
We report the detection of the Sunyaev-Zel'dovich (SZ) effect of galaxy
cluster XLSSU J021744.1-034536, using 30 GHz CARMA data. This cluster was
discovered via its extended X-ray emission in the XMM-Newton Large Scale
Structure survey, the precursor to the XXL survey. It has a photometrically
determined redshift , making it among the most distant
clusters known, and nominally the most distant for which the SZ effect has been
measured. The spherically integrated Comptonization is
, a measurement which is relatively
insensitive to assumptions regarding the size and redshift of the cluster, as
well as the background cosmology. Using a variety of locally calibrated cluster
scaling relations extrapolated to z~2, we estimate a mass - from the X-ray flux and SZ signal. The measured
properties of this cluster are in good agreement with the extrapolation of an
X-ray luminosity-SZ effect scaling relation calibrated from clusters discovered
by the South Pole Telescope at higher masses and lower redshifts. The full
XXL-CARMA sample will provide a more complete, multi-wavelength census of
distant clusters in order to robustly extend the calibration of cluster scaling
relations to these high redshifts.Comment: ApJ, in press. 9 pages, 4 figures, 4 table
Raltitrexed (Tomudex) administration in patients with relapsed metastatic colorectal cancer after weekly irinotecan/5-Fluorouracil/Leucovorin chemotherapy
PURPOSE: The present study aimed at evaluating the efficacy of Raltitrexed, a specific thymidilate synthase inhibitor, in patients with advanced colorectal cancer (ACC) in relapse (>8 weeks) after a prior response or disease stabilization to first-line chemotherapy combination with lrinotecan+5-Fluorouracil (5-FU)+Leucovorin (LV). METHODS: Twenty-five patients with metastatic ACC entered; 17 males/8 females, median age 61 (range: 47–70), median Karnovsky PS: 80 (70–90), and sites of metastases; liver: 21, lung: 4, lymph nodes: 7, peritoneal: 5 and a life expectancy of at least 3 months, were entered in the present pilot study. All patients had progressed after prior chemotherapy with lrinotecan+5-FU+LV. Raltitrexed was administered at a dose of 3 mg/m(2) i.v. every 21 days. RESULTS: Three patients (12%) achieved a partial response (PR), 8 (32%) had stable disease (SD), and the remaining 14 (56%) developed progressive disease (PD). Median time-to-progression (TTP) was 5.5 months (range, 2–8.5), and median overall survival (OS) 8 months (range, 4.0–12.5). Toxicity was generally mild; it consisted mainly of myelosuppression; neutropenia grade 1–2: 52%-grade 3: 28%, and anemia grade 1–2 only: 36%. Mild mucositis grade 1–2 occured in 13.5% of patients and was the principal non-hematologic toxicity. CONCLUSION: Response to treatment with Raltitrexed is limited in patients with ACC failing after an initial response or non-progression to the weekly lrinotecan+5-FU+LV combination. However, it appears that a limited number of patients with PR/SD may derive clinical benefit, but final proof would require a randomized study

The 1430s: a cold period of extraordinary internal climate variability during the early Spörer Minimum with social and economic impacts in north-western and central Europe
Changes in climate affected human societies throughout the last millennium. While European cold periods
in the 17th and 18th century have been assessed in detail, earlier cold periods received much less attention due to sparse information available. New evidence from proxy archives, historical documentary sources and climate model simulations permit us to provide an interdisciplinary, systematic assessment of an exceptionally cold period in the 15th century. Our assessment includes the role of internal, unforced climate variability and external forcing in shaping extreme climatic conditions and the impacts on and responses of the medieval society in north-western and central Europe. Climate reconstructions from a multitude of natural and anthropogenic archives indicate that the 1430s were the coldest decade in north-western and central Europe in the 15th century. This decade is characterised by cold winters and average to warm summers resulting in a strong seasonal cycle in temperature. Results from comprehensive climate models indicate consistently that these conditions occurred by chance due to the partly chaotic internal variability within the climate system. External forcing like volcanic eruptions tends to reduce simulated temperature seasonality and cannot explain the reconstructions. The strong seasonal cycle in temperature reduced food production and led to increasing food prices, a subsistence crisis and a famine in parts of Europe. Societies were not prepared to cope with failing markets and interrupted trade routes. In response to the crisis, authorities implemented numerous measures of supply policy and adaptation such as the installation of grain storage capacities to be prepared for future food production shortfalls

Foreword
This special issue n° 125 (2015) of the Journal of Mediterranean Geography (JMG), devoted to coastal wetlands, is new step in a series of issues exploring, for two decades now, the diversity and quality of past and present relationships between societies and coastal zones in the Mediterranean. By the early 1990s, a detailed issue about dynamics of the Rhône delta and the Camargue area was supervised and edited by the geographer and geomorphologist Mireille PROVANSAL (JMG, 1993/78 3-4,), but g..
Introduction
Ce numéro 125 (2015) de la revue Méditerranée, dédié aux zones humides littorales en Méditerranée, s’inscrit dans la continuité d’un cycle de réflexion axé sur les espaces côtiers et maritimes qui, depuis maintenant deux décennies, a déjà permis d’explorer diverses facettes de leur(s) dynamique(s), relatives aussi bien à des phénomènes géomorphologiques du temps long qu’à des questions actuelles ou prospectives liées aux intenses - intimes - relations société-environnement qui existent en leu..
