87. Three PG students were assessed using the validated tools thrice for the three selected EPAs. The PGs opined that assessment using rubrics made their task-specific, while faculties were quite satisfied with the assessment process as it removed subjectivity. Conclusions The developed and selected tools of EPAs were found to have a substantial level of both face validity and content validity. The tools were also found to useful for periodic assessment in workplace settings and acceptable to both PG students and internal/external faculty members.We report 105Pd nuclear magnetic resonance (NMR) and nuclear quadrupolar resonance (NQR) measurements on a single crystal of Ce3Pd20Si6, where antiferroquadrupolar and antiferromagnetic orders develop at low temperature. From the analysis of NQR and NMR spectra, we have determined the electric field gradient (EFG) tensors and the anisotropic Knight shift (K) components for both inequivalent Pd sites-Pd(32f) and Pd(48h). The observed EFG values are in excellent agreement with our state-of-the-art density functional theory calculations. The principal values of the quadrupolar coupling are [Formula see text] MHz and [Formula see text] MHz, for the Pd(32f) and Pd(48h) sites, respectively, which is large compared to the Larmor frequency defined by the gyromagnetic constant [Formula see text] MHz/T for 105Pd. Therefore, the complete knowledge of K and the EFG tensors is crucial to establish the correspondence between NMR spectra and crystallographic sites, which is needed for a complete analysis of the magnetic structure, static spin susceptibility, and the spin-lattice relaxation rate data and a better understanding of the groundstate of Ce3Pd20Si6.The iron (II) spin crossover complex Fe(1,10-phenanthroline)2(NCS)2, dubbed Fe-phen, has been studied with scanning tunnelling microscopy, after adsorption on the "herringbone" reconstructed surface of Au(111) for sub-monolayer coverages. The Fe-phen molecules attach, through their NCS-groups, to the Au atoms of the fcc domains of the reconstructed surface only, thereby lifting the herringbone reconstruction. The molecules stack to form 1D chains, which run along the Au [110] directions. Neighboring Fe-phen molecules are separated by approximately 2.65 nm, corresponding to 9 atomic spacings in this direction. The molecular axis, defined by the two phen groups, is aligned perpendicular to the chain axis, along the Au[221 ̅ ]. direction, thereby bridging over 5 atomic spacings, in this direction. Experimental evidence suggests that the molecular spins are locked in a mixed state in the sub-monolayer regime at temperatures between 100 K and 300 K.

Epitaxial strain is found to change the magnetic ordering and surface effects are shown to alter the critical exponents for phase transitions. The magnetic coherence across spacer layers is found to depend on the band structure of the superlattice as a whole, and the conduction-electron spin-density wave responsible for interlayer magnetic coupling is measured directly.

Hitherto, commentators' reviews rely on imposing but narrow streams of evidence to either ignore Vidgen's influence on the dental profession or portray it as both peripheral and controversial. In this account, the authors use historical method to provide a revisionist account of Vidgen's professional profile and, to a lesser extent, a character resurrection. Vidgen was probably introverted. His orientation relating to dental education became obsolete, inappropriate and disruptive. Vidgen's actions, beliefs and values incurred sustained and organized opposition from academe, the Australian Dental Association Queensland Branch, the Odontological Society of Queensland and some private practitioners. The sociopolitical context, namely the Great Depression and affiliated reconstruction, the community's demand for government-administered dental services, World War II, twenty-five years of continuous Australian Labor Party government in Queensland, Edward Hanlon's authoritarianism and the emergence of a welfare state were also relevant to Vidgen's becoming a nonconformist, nonjoiner and an outcast. However, the authors posit that, for the socially disadvantaged and the regionally and remotely domiciled, Vidgen was a humanitarian and a quiet social reformer who, under Hanlon's authority and tutelage, pioneered enduring changes to the delivery of dental services across Queensland.

To date (although it has been indirectly suggested) there have been no published attempts to reproduce the disputed holes identified in the Egyptian mandibles with tools fabricated from stone and bronze, the materials that were available to ancient Egyptian artisans. This paper presents an abbreviated assessment of oral surgery in ancient Egypt regarding these procedures, with an attempt to reproduce these procedures on fresh pig and embalmed cadaver jaws as proxies for vital human bone, using hand drills that were fabricated of bronze and chet.

Guralnick, a major figure in Oral and Maxillofacial Surgery, educational innovator, master surgeon and mentor died, surrounded by family, on September 6, 2017 at Massachusetts General Hospital, the institution he loved and served for 65 years. Like others of his generation, Dr Guralnick served in the Armed Services in Europe during World War II. Little was known of his activities with the 7th General Hospital and of his contributions to the war effort. This paper brings together material from military, local and overseas archives to provide an insight into his life and work during those years.
