To investigate systematically the effects of Re and other elements on deuterium (D) retention, W binary W-alloys (Re, Mo Ta) were irradiated with 6.4 MeV Fe ions at high temperatures (1073–1273 K) then exposed to D 2 gas 673 K. Depth profiles measured by nuclear reaction analysis (NRA), retention was determined thermal desorption spectrometry (TDS) NRA. The addition 5 at.% into reduced content ...

This study examined the influence of gender on individual risk perception. The analysis covered 17 involuntary risks and effects three dimensions - likelihood, impact overall rating. results showed that while magnitude significance coefficients varied by risk, a general pattern was apparent: females judged as being more likely, having greater impact, or higher rating than their male counterpart...

Amistad National Recreation Area is a 23,186 ha property in Val Verde County, Texas. A floral inventory was conducted in 2003–2004, producing a checklist of 699 taxa with 99 infraspecific taxa, 686 species, 402 genera, and 106 families. There are 651 native taxa and 48 introduced. No federally or state listed plants were documented. Seventeen species of conservation concern were verified within...

l-Canavanine inhibits the appearance of nitrate reductase (NADH-nitrate oxidoreductase, EC 1.6.6.1) in both root tips and mature root sections of corn (Zea mays L.). Ten-fold more canavanine was required to cause a 50% reduction in the level of nitrate reductase activity (NRA) in root tips than in mature root sections. For example with one particular batch of seeds 500 mum canavanine was effect...

Enhanced nitrogen use efficiency (NUE) in turfgrass systems comprises several factors, including more efficient uptake and assimilation of applied (N), as well reduced N losses to the environment. The objectives current research were evaluate inter- intraspecific variation parameters two Agrostis species, creeping bentgrass (Agrostis stolonifera L.) velvet canina L.), under field controlled env...

Abstract This paper presents and proves totally correct a new algorithm, called $$\textsf{QSMA}$$ QSMA , for the satisfiability of quantified formula modulo complete theory an initial assignment. The optimized variant implemented in YicesQS is described shown to preserve total correctness. A report on perform...

TINA aims to provide an architecture based on distributed computing technologies that will enable telecommunications networks to support the flexible introduction and control of new advanced services. The provided services and the supporting network and computing infrastructure will be managed in an integrated fashion. Network management aspects in TINA are addressed by its Network Resource Arc...
