Background:Cross-sectoral coordination of treatment plans and efficient management of patients with chronic diseases and co-morbidities are of great importance. In rheumatoid arthritis (RA) it is essential to orchestrate information available for a p

The quantitative role of different segments of the gastrointestinal tract for Ca absorption, the respective mechanisms, and their regulation are not fully identified for ruminants, that is, cattle. In different in vitro experiments the forestomach wa

The adsorption geometry of the surface methoxy species (-OCH 3 ) on Cu(111) has been determined quantitatively using scanned energy mode photoelectron diffraction in a two-step approach. First, using direct methods it was established that the fragmen

Using model calculations for a Cu25OCH3 cluster the bonding interaction between the methoxy species and a Cu{111} surface has been investigated. In agreement with recent photoelectron diffraction measurements, OCH3 is found to adsorb preferentially i

Photoelectron diffraction data for Ag3d emission from ( 3 × 3 R 30° Ag on Si(111) have been obtained in all three possible modes: scanned polar angle, scanned azimuthal angle, and scanned energy. Single and multiple scattering cluster calculations

The electronic structure of the surface carbonate species adsorbed on Ag{110} has been studied with angle‐resolved photoemission using synchrotron radiation. Despite the low symmetry of the surface complex (Cs) and more than one azimuthal orientati

Vibrational spectroscopy of NO on Ni(111) shows two distinct N–O stretching bands for adsorption on the clean surface at different coverages which have been attributed to tilted and perpendicular bridging species at low and high coverage, respectiv
