Preliminary results of experiments on D2 gas permeation using a system [vacuum/CaO/Sr/PdD x/D2] have shown some evidence of nuclear transmutation from Sr to Mo. The system is a little simpler than that used by Iwamura et al., and has a reversed gas flow direction. The diagnostic method used to identify the elements was conventional XPS, giving the areal densities of 4.21014 cm-2 (Sr) and 3.31...

It is hard to find a class of natural language phenomena which exhibits more complex interactions between syntax and semantics than comparative constructions. Comparatives come with phrasal or clausal complements. In this paper, we focus on phrasal comparatives, which on first inspection look simpler than the clausal ones, but in fact add a degree of complexity. We will consider predicative com...

Additional network complexity driven by the demand for new broadband services increases the need for network control and management signalling. This paper takes stock of this trend and suggests an approach within the context of IEEE P.1520 to separate signalling and associated broadband intelligent services from multimedia data transport so that each may be developed to their full potential. Th...

BACKGROUND We used High Resolution - peripheral Quantitative CT (HR-pQCT) imaging to examine peri-articular bone quality in early rheumatoid arthritis (RA) and explore whether bone quality improved over 12-months in individuals receiving care consistent with practice guidelines. METHODS A 1-year longitudinal cohort study (Baseline and 12-months) evaluating individuals with early RA compared t...

The present study analyses wage income inequality in Bulgaria during the period 2010-2019, using data from National Revenue Agency (NRA) on actual incurred of taxpayers and survey Household Budget Survey Statistical Institute (NSI). Key indicators are derived under both approaches, which compared evaluated through descriptive analysis. NSI permanently underestimates level its distribution, as e...

Boron and phosphorus were implanted in p-type and n-type silicon wafers in the energy range from 0.1 to 1.5 MeV. Three different methods were used to determine the distribution of the ions: SIMS, CV and NRA. The results were fitted to a Pearson IV distribution in order to extract moments for describing the distributions analytically. The projected ranges agree well with the theoretical values. ...

Boron-containing materials exhibit a unique combination of ceramic and metallic properties that are sensitively dependent on their given chemical bonding elemental compositions. However, determining the composition, let alone bonding, with sufficient accuracy is cumbersome respect to boron, being light element bonds in various coordinations. Here, we report comprehensive compositional analysis ...
