Adaptive management of applications across multiple clouds:the SeaClouds approach

How to deploy and manage, in an efficient and adaptive way, complex applications across multiple heterogeneous cloud platforms is one of the problems that have emerged with the cloud revolution. In this paper we present context, motivations and objectives of the EU research project SeaClouds, which aims at enabling a seamless adaptive multi-cloud management of complex applications by supporting the distribution, monitoring and migration of application modules over multiple heterogeneous cloud platforms. After positioning SeaClouds with respect to related cloud initiatives, we present the SeaClouds architecture and discuss some of its aspect, such as the use of the OASIS standard TOSCA and the compatibility with the OASIS CAMP initiative

Production and quality control of GEM detectors for the Phase 1 upgrade of the CMS experiment

The CMS collaboration has approved the installation of an additional set of muon detectors based on triple-GEM technology in the first endcap muon station known as GE1/1 [1]. They will be installed in 2019 during the second Long Shutdown (LS2) planned by LHC. The chambers will be built by different production sites in Europe, Asia and the United States. In each production site, the chamber quality and performance are measured by systematic inspections and standardized procedures to ensure the timely delivery of fully efficient detectors to CMS

Production and quality control of the new chambers with GEM technology in the CMS muon system

The CMS collaboration has approved the installation of an additional set of muon detectors based on triple-GEM technology in the first endcap muon station known as GE1/1. They will be installed in 2019 during the second Long Shutdown (LS2) planned by LHC. A first set of chambers have been already built by different production sites in Europe, Asia and the United States. Systematic inspections and strict quality controls, scheduled for the GE1/1 chambers approval by the central site (Cern), were carried out successfully in Bari (Italy). Seven short GE1/1 chambers of tenth generation out of 13 for the first end-cap have been already delivered to Cern. The new chambers quality and performances attest the notable contribution of Bari site to complete the GE1/1 muon detector station for the next upgrade of the CMS experiment. The results of the quality control procedures concerning the effective gain and the response uniformity of the delivered detectors will be shown together with the results on other relevant parameters like internal pressure drop, maximum spurious signal rate and normalized resistance as well

MYCOTOXIN DETECTION IN INFANT FORMULA MILKS IN ITALY

International audienceAfter birth, infant formulas constitute an important or often sole food source for infants during the first life months. In this study, a survey on the presence of aflatoxin M1 (AFM1) and ochratoxin A (OA) in the 14 leading brands of infant formulas marketed in Italy was conducted. Mycotoxins were determined by immunoaffinity column clean-up and HPLC with fluorescence detection. AFM1 was found in 2 out of 185 samples but at levels below the European legislation limit of 25 ng/L. OA was detected in 133 (72%) samples (range 35.1-689.5 ng/L). It has been observed that OA contamination was 80% in the ready-to-use preparations and 63% in the powdered samples. The Scientific Committee for Food (SCF) reviewed the toxicology on OA and concluded that it would be prudent to reduce exposure to OA ensuring that exposures are towards the lower end of the range of tolerable daily intakes of 1.2-14 ng/kg b.w. per day. OA was also evaluated by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and a provisional tolerable weekly intake (PTWI) of 100 ng/kg b.w. was established. The OA levels in pre-term ready-to-use infant formulas were sufficient to cause a higher OA intake than the suggested TDI. Our results point out the need to perform controls for prevention programs especially when attempting to identify risk markers of the infant feed quality

Enantiopure 3-(arylmethylidene)aminoxy-2-methylpropionic acids: synthesis and antiinflammatory properties

Some optically active 3-(arylmethylidene)aminoxy- (3a-g, 4a-g) and fluorenylideneaminoxy-2-methylpropionic acids (5, 6), were prepared as analogues of the antiinflammatory arylpropionic acids of type B, in which the aromatic group is substituted by an MAOM moiety. Some of the new compounds. tested in vivo for their antiinflammatory properties by means of the carrageenan-induced paw edema method in rats, exhibited activity indices similar to that shown in the same test by ibuprofen. Compounds 3a.b and 4a,b, for which at least one of the two enantiomers had shown an inhibition value higher than 40% in the in vivo test, were assayed for their in vitro enzymatic inhibitory activity. showing percentage inhibition values between 40 and 50% at a concentration of 10 muM against COX-2: at the same concentration, they appeared to be devoid of any activity towards COX-1. Compounds 3a.b and 4a,b also proved to possess a similar toxicity. The lack of enantioselectivity shown by compounds 3-6 was tentatively explained in terms of a conformational freedom of the enantiomers which allows their quasi-superimposition
