in the present study we search potential of pt-decorated graphene (ptg) as a new nanostructure adsorbent for nitrous oxide (n2o) using density functional theory (dft). after fully relaxation of different possible orientations of n2o-ptg complex, we distinguished two optimized configurations for this system; 1- terminal n-side of gas is oriented towards pt so that the molecule axis is perpendicu...

BACKGROUND Peer Assessment (PA) in health professions education encourages students to develop a critical attitude towards their own and their peers' performance. We designed a PA task to assess students' clinical skills (including reasoning, communication, physical examination and treatment skills) in a role-play that simulated physical therapy (PT) practice. Students alternately performed in ...

in the present work, the electrooxidation of formic acid and formaldehyde; potentially important fuels for future fuel cells, was investigated on the fe3o4@pt core-shell nanoparticles/carbon-ceramic electrode (fe3o4@pt/cce). the fe3o4@pt nanoparticles were prepared via a simple and fast chemical method and their surface morphology, nanostructure properties, chemical composition, crystal phase, ...

Motivated by the long-term goal of understanding vectorial biological processes such as proton transport (PT) in biomolecular ion pumps, a number of developments were made to establish combined quantum mechanical/molecular mechanical (QM/MM) methods suitable for studying chemical reactions involving significant charge separation in the condensed phase. These developments were summarized and dis...

The present study is an integrated approach to the Pt, Pd, and Rh cycling derived from catalytic converters along highway roadsides of Athens Basin, including their contents, dispersed Pt- Pd-bearing nano- microparticles in dust bioaccumulation plants, aiming assess auto-catalyst-derived environmental impact large city potential human health risk. determined mean values 314 510 23 (all μg/kg) s...

Background: Phlebitis is a complication associated with peripheral intravenous catheters and an adverse event.Objective: To analyze catheter-associated phlebitis incidents drug administration to adult inpatients their consequences. Methodology: Quantitative, retrospective, descriptive, cross-sectional study. Non-probabilistic convenience sampling technique was used, 96 patients hospitalized in ...

The first measurements of the Fourier coefficients (VnΔ) azimuthal distributions charged hadrons emitted from photon-proton (γp) interactions are presented. data extracted 68.8 nb−1 ultra-peripheral proton-lead (pPb) collisions at sNN=8.16TeV using CMS detector. high energy lead ions produce a flux photons that can interact with oncoming proton. This γp system provides set unique initial condit...
