EUROTRANS
No full textThe Integrated Project EUROTRANS (EURopean Research Programme for the TRANSmutation of High Level Nuclear Waste in an Accelerator Driven System) within the ongoing EURATOM 6th European Commission Framework Programme (FP6) is devoted to the study of transmutation of high-level waste from nuclear power plants. The work is focused on transmutation in an Accelerator Driven System (ADS). The objective of EUROTRANS is the assessment of the design and the feasibility of an industrial ADS prototype dedicated to transmutation. The necessary R&D results in the areas of fuel development, structural materials, thermal-hydraulics, heavy liquid metal technology and nuclear data will be made available, together with the experimental demonstration of the ADS component coupling. The outcome of this work will allow to provide a reasonably reliable assessment of technological feasibility and a cost estimate for ADS based transmutation, and to possibly decide on the detailed design of an experimental ADS and its construction in the future. EUROTRANS is integrating critical masses of resources (23M€ EC contribution, 43M€ total eligible costs) and activities of 47 participants from 14 countries, within the industry (10 participants), the national research centres (19) and 17 universities in Europe. The universities are collectively represented by ENEN (European Nuclear Engineering Network). EUROTRANS is the logical continuation of the three FP5 Clusters FUETRA, BASTRA and TESTRA together with the PDS-XADS Project. It takes credit from the Roadmap on P&T of the Technical Working Group [1]. EUROTRANS strengthens and consolidate the European research and development activities in transmutation. The involvement of universities strengthens education and training in nuclear technologies. The involvement of industries assures a market-oriented and economic design development and an effective dissemination of the results.Completato€ 65.00
INDUSTRIA 2015 PEC
No full textThe Program entitled "MILD Technology Integration in innovative combustion system characterised by low emissions" will develop the application of the MILD Combustion Technology in the strategic industrial sectors of steel and electricity in our Country, where energy efficiency is a key aspect. The advantages of applying MILD technology to the steel and energy sectors could be transferred to other important industrial sectors characterised by high energy needs, such as glass, cement and metallurgy sectors. The program foresees MILD technology being implemented in the following four combustion systems:
a reactor for an oxy coal combustion plant with carbon capture sequestration
a gas turbine burner
a steam boiler burner
a steel heating furnace.
The program strategy is to create a synergy between big and small enterprises and research organizations to achieve a commercial exploitation overcoming the technological limits that the development of the prototypes, based on MILD combustion technology, requires. The aim of the program is to demonstrate the applicability of the MILD combustion technique to key industrial processes through the realization of full scale prototypes. The prototypes will be characterised in term of the feasibility, emissions and efficiency obtained using the MILD technique thanks to the uniformity of temperature and thermodynamic variables, distinctive to the MILD technique. These benefits will make the technique a useful instrument to be used in reaching the objectives of the Energy Efficiency Call.Completato€ 195.80

A CRS4 spallation Target for ESS Simulations with starccm+V5.0
Get PDFIn this document, we present a series of CFD simulations performed with starccm+V5 to build a sound proposal of windowless channel spallation target for ESS. The simulations increase progressively in complexity. The first simulation is a simple Mercury loop under the effect of a pulsed proton beam. The second one also includes a Hg/vacuum dynamic interface, using the VOF algorithm. The last simulations consider a LBE loop under vacuum subject to the thermal interaction with a proton beam, and is the basis for the proposal to ESS, still using the VOF algorithm. The simulation could be completed in a satisfactory way thanks to the use of a specific sharpening algorithm. This algorithm is explained and commented. The last simulations implementation is also described in details. The final results are shown. They appear very satisfying because the sharpening algorithm performs very well without giving rigidity to the free-surface and because the design elaborated seems a very promising basis for an ESS spallation target
High Quality Interactive Rendering of Massive Point Models using Multi-way kd-Trees
Get PDFWe present a simple and efficient technique for out-of-core multi resolution construction and high quality visualization of large point datasets. The method introduces a novel hierarchical LOD data organization based on multi-way kd-trees that simplifies memory management and allows controlling the LOD tree's height. The technique is incorporated in a full end-to-end system, which is evaluated on complex models made of hundreds of millions of points.93-10

The liposoluble proteome of Mycoplasma agalactiae: an insight into the minimal protein complement of a bacterial membrane
Get PDFBackground: Mycoplasmas are the simplest bacteria capable of autonomous replication. Their evolution
proceeded from gram-positive bacteria, with the loss of many biosynthetic pathways and of the cell wall. In this
work, the liposoluble protein complement of Mycoplasma agalactiae, a minimal bacterial pathogen causing
mastitis, polyarthritis, keratoconjunctivitis, and abortion in small ruminants, was subjected to systematic
characterization in order to gain insights into its membrane proteome composition.
Results: The selective enrichment for M. agalactiae PG2T liposoluble proteins was accomplished by means of Triton
X-114 fractionation. Liposoluble proteins were subjected to 2-D PAGE-MS, leading to the identification of 40 unique
proteins and to the generation of a reference 2D map of the M. agalactiae liposoluble proteome. Liposoluble
proteins from the type strain PG2 and two field isolates were then compared by means of 2D DIGE, revealing
reproducible differences in protein expression among isolates. An in-depth analysis was then performed by GeLCMS/
MS in order to achieve a higher coverage of the liposoluble proteome. Using this approach, a total of 194
unique proteins were identified, corresponding to 26% of all M. agalactiae PG2T genes. A gene ontology analysis
and classification for localization and function was also carried out on all protein identifications. Interestingly, the
11.5% of expressed membrane proteins derived from putative horizontal gene transfer events.
Conclusions: This study led to the in-depth systematic characterization of the M. agalactiae liposoluble protein
component, providing useful insights into its membrane organization.225-236Pubblicat
