We investigate the solid phases of the restricted primitive model (RPM). Monte Carlo simulations show the existence of an order-disorder transition from a substitutionally disordered face centered cubic lattice (fcc) to a new ordered fcc structure which is proposed as the ground state of the RPM at the close packing density. Our results suggest that the new phase might turn out in a new triple ...

Combining transmission electron microscopes and density functional theory calculations, we report the nucleation and growth mechanisms of room temperature rolling induced face-centered cubic titanium (fcc-Ti) in polycrystalline hexagonal close packed titanium (hcp-Ti). Fcc-Ti and hcp-Ti take the orientation relation: 〈0001〉hcp||〈001〉fcc and , different from the conventional one. The nucleation ...

the catalytic cracking of a fuel oil over fluid catalytic cracking (fcc) catalyst has been investigated applying different additives. catalyst mixtures consisting of a equilibrium fcc catalyst (e-cat) blended with zsm-5, mcm-41 and mordenite additives were examined at the additive levels of 25 wt.%. the catalytic performance of the matrix was studied in a fixed bed micro-activity test unit (mat...

The Federal Communications Commission’s (FCC) charge to promote the public interest in the communications sector encompasses a mandate to foster competition.1 The FCC is far from the only federal agency with an interest in competitive communications markets. The Antitrust Division of the Department of Justice (DOJ) and the Federal Trade Commission (FTC), the nation’s generalist antitrust enforc...

To understand the effects of lattice mismatch on heteroepitaxial growth, we have studied equilibrium structure and orientation relationships (ORs) FCC films grown epitaxially substrates, using molecular dynamics simulations in conjunction with embedded atom method potentials. Three film/substrate systems been investigated, namely: Ag Cu, Ni Pb Al. These cover a significant range mismatch, from ...

INTRODUCTION Healthcare quality is usually evaluated through analysing medical outcomes including neonatal readmission and patient and family satisfaction. Parental involvement in neonatal care is considered as one of the most important factors, which directly affects these outcomes. The aim of the present study was to determine the effect of family-centered care including maternal participatio...

BACKGROUND Family-Centred Care (FCC) is recognized as an important component of all paediatric care, including neonatal care, although practical clinical guidelines to support this care model are still needed in Italy. The characteristics and services for families in Italian NICUs show a lack of organization and participation. METHODS The first aim was to compare satisfaction and stress level...

A Monte Carlo simulation study is made of the phase diagram of the restricted primitive model and of the solid± liquid and solid± solid phase coexistence curves in particular. At low temperatures, there is liquid± bcc coexistence and with increasing density there is bcc± fcc coexistence. These coexistence curves end in a triple point (liquid± bcc ± fcc) above which only liquid± fcc coexistence ...

We report results of total energy and electronic structure calculations of fcc and bcc silver bulk and surfaces. We find that under normal conditions (positive pressure) bcc silver is not stable. However, if silver is grown with a volume per atom & 10% larger than that of the well-known fcc silver, the total energy of the bcc structure becomes below that of fcc silver. For bcc (110) a surface s...
