provides an overview of subject repositories (srs) throughout the world in response to the open access movement (oam). it mainly highlights the current trends of repository development in library and information science (lis) field. this paper covers all repositories in lis field as registered in opendoar (directory of open access repository) database. the main objective of the paper is to sele...

Introduction To predict the evolution of a Geological Disposal Facility, it is necessary to understand the interaction between a number of key features and process and its impact on the long-term behaviour. Central to these issues are the mechanisms and process that govern the movement of gases in a repository. Linking the gas transport to the stress-strain response of the engineering systems b...

To assist transport modeling in assessments of the radiological impact of a geological repository for radioactive wastes, the mobility of various elements was studied in arable and wetland soils in the Forsmark region, Sweden. Pore water and total element contents were determined for five types of unconsolidated deposits (regolith), spanning a wide range of soil properties with respect to pH an...

Abstract Cr-doped UO 2 -based model materials were prepared at SCK CEN, mimicking modern LWR fuels, to understand the influence of Cr doping on spent fuel dissolution behaviour in geological repository conditions. Tests carried out with four materials: depleted , Pu-doped and Pu-Cr-doped . Static experiments have been performed up 4 months autoclaves under 10 bar H pressure a Pt/Pd catalyst med...

The Neoproterozoic era was arguably the most revolutionary in Earth history. Extending from 1000 to 541 million years ago, it stands at the intersection of the two great tracts of evolutionary time: on the one side, some three billion years of pervasively microbial 'Precambrian' life, and on the other the modern 'Phanerozoic' biosphere with its extraordinary diversity of large multicellular org...

Northern Chile is home to the world’s largest copper ore deposits, which have been exploited for thousands of years by different groups, at varying scales and purposes. In this context, it important develop new protocols characterise mineralogical variability archaeological ores. A comprehensive representative methodology in analysis minerals, application non-destructive analytical techniques, ...
