After the Fukushima Daiichi nuclear power plant (NPP) accident, new regulatory requirements were enforced in July 2013 and a backfit was required for all existing nuclear power plants. It is required to take measures to prevent severe accidents and mitigate their radiological consequences. The Regulatory Standard and Research Department, Secretariat of Nuclear Regulation Authority (S/NRA/R) has...

We present the design and operation of a specialized Atomic Layer Deposition (ALD) system, dedicated to stable isotopic tracing experiments oxide film growth, using isotopically labelled water as reactant. A small chamber volume allows with only very quantities vapor, minimising consumption water. The first results for growth ZnO TiO2 Diethlyzinc (DEZ) Tetrakis(dimethylamino)titanium (TDMAT) zi...

Prostaglandin E2 (PGE2) has been demonstrated to attenuate cardiac ischemia-reperfusion (I/R) injury. However, the underlying mechanism of PGE2 in cardiac I/R injury remains unknown. Upregulated expression levels of vascular endothelial growth factor (VEGF) and endothelial nitric oxide synthase (eNOS) were reported in acute myocardial infarction (AMI), and were demonstrated to diminish I/R inju...

The most effective way to promote Next Generation Access coverage and ultra-broadband penetration is through infrastructure competition. In Countries having well-developed cable networks this market condition preexists. Where CaTV is limited or null, one way to surrogate its powerful procompetitive effect is through the VDSL2/FttC architecture stimulating competition among operators. This has b...

The capacity for nitrate reduction, as measured by nitrate reductase activity (NRA), was generally low for a range of plant communities in Australia (coastal heathland, rainforest, savanna woodland, monsoon forest, mangrove, open Eucalyptus forest, coral cay open forest) and only a loose relationship existed between NRA and leaf nitrogen concentration. This suggests that nitrate ions are not th...

In this paper, an adaptive framework for audio retrieval in live teleconferencing environments with multiple participants is proposed. The framework uses a non reference anchor array (NRA) to capture the interfering speech sources, in addition to the primary array that captures the speech source of interest (SOI). A linearly constrainedminimum variance (LC-MV) beamformer is used herein such tha...

During the last five years of operation of Atucha I Nuclear Power Plant (CNA I) and Embalse Nuclear Power Plant (CNE), a field team from the Environmental Radioactivity Division of Nuclear Regulatory Authority (NRA) has carried out surveillance programs in the surroundings of these facilities, in order to estimate the radiological impact. The argentine nuclear power plants use natural uranium a...
