Summary report on CSNI/RILEM workshop on use and performance of concrete in NPP fuel-cycle facilities
A summary report on Committee on the Safety of Nuclear Installations/ International Union of Laboratories and Experts in Construction Materials (CSNI/RILEM) was presented. The presentation addressed generation, characterization and management of radioactive waste, fuel-cycle facilities, disposal of radioactive waste and general conclusions and recommendations. To ensure continued performance of critical structures, life limiting features were identified and matched against the available methods of testing and examination. The operational waste would be encapsulated and stored in an on-site-intermediate-level-waste store that would be built on the foundations of the demolished turbine hall

Pseudomorphic SiGe/Si(001) layers synthesized by gas immersion laser doping
We report on the synthesis of SiGe layers on silicon by gas immersion laser doping. GeCl(4) molecules are adsorbed on the surface and further incorporated into the Si top layer by a pulsed laser induced melt/regrowth process. Structural and chemical characterizations of the SiGe layers have been performed by using complementarily Rutherford backscattering spectrometry and x-ray Diffraction which indicate that Ge incorporation in the Si matrix results in a fully strained SiGe layer with gradual Ge concentrations reaching up to 18.5% near the surface.

Genomic and Phylogenetic Analysis of Hepatitis C Virus Isolates from Argentine Patients: a Six-Year Retrospective Study
Typing of hepatitis C virus (HCV) isolates from Argentine patients was performed by using different methodologies in a population of 243 patients. HCV subtype was assigned based upon restriction fragment length polymorphism (RFLP). HCV RNA genomes obtained from serum samples were classified as belonging to clade 1 (53.5%), 2 (23.0%), or 3 (8.6%); 14.8% of samples showed HCV mixed infections, more frequently implying different subtypes within the same clade. In addition to RFLP typing, phylogenetic relatedness among sequences from both 5′ untranslated region (n = 50) and nonstructural 5B coding region (n = 15) was established
GB Virus C/Hepatitis G Virus Groups and Subgroups: Classification by a Restriction Fragment Length Polymorphism Method Based on Phylogenetic Analysis of the 5′ Untranslated Region
A phylogenetic tree based on 150 5′ untranslated region sequences deposited in GenBank database allowed segregation of the sequences into three major groups, including two subgroups, i.e., 1, 2a, 2b, and 3, supported by bootstrap analysis. Restriction site analysis of these sequences predicted that HinfI and either AatII or AciI could be used for genomic typing with 99.4% accuracy. cDNA sequencing and subsequent alignment of 21 Argentine GB virus C/hepatitis G virus strains confirmed restriction fragment length polymorphism patterns theoretically predicted. This method may be useful for a rapid screening of samples when either epidemiological or transmission studies of this agent are carried out
