Public sector doctor relations with their employer, soured by clumsy, inconsistent provincial implementation of long-awaited Occupation Specific Dispensation, (OSD), pay hikes and further delayed mid-level category doctors pay talks, are on a knife edge.

Purpose. To evaluate implant survival, peri-implant bone loss, and complications affecting fixed full-arch (FFA) restorations supported by implants with a knife-edge thread design and nanostructured, calcium-incorporated surface. Methods. Between January 2013 and December 2015, all patients referred for implant-supported FFA restorations were considered for enrollment in this study. All patient...

Ihedioha U, et al. BMJ Case Rep 2017. doi:10.1136/bcr-2017-219648 DESCRIPTION A 31-year-old man presented to the accident and emergency department with a penetrating injury to his left posterolateral chest wall. He was haemodynamically stable, and there was no significant bleeding from the entry point. Plain anterior radiography (figure 1) of the chest revealed a knife embedded within the extra...

The presented work deals with an analysis of causes the very low service life new version hand woodworking planing knife, which has replaced original a knife. Based on performed experimental works, chemical analysis, macroscopic and microscopic observation, SEM, diffractometric Vickers hardness test it was concluded that cause for (practically nonexistent one) knife are significant features ove...

With the recent adoption of millimeter-wave spectrum in cellular communications, deployment active antenna arrays and use beamforming become vital to compensate for increased path loss. However, directional high-frequency signals may suffer heavy attenuations due blockage effects. Therefore, modelling that adequately incorporates effects becomes increasingly relevant. We propose a Four Knife-Ed...

A 50-years old female patient presented for treatment of the anterior maxillary teeth that had been restored repeatedly in the past with direct resin composite restorations. The treatment plan for this patient included all-ceramic shell crowns on all anterior maxillary teeth and the premolars. Shell crowns were selected as the treatment option to ensure optimum esthetic result with increased st...

We present a mechanical rotation sensor consisting of a balance pivoting on a tungsten carbide knife edge. These sensors are important for precision seismic isolation systems, as employed in land-based gravitational wave interferometers and for the new field of rotational seismology. The position sensor used is an air-core linear variable differential transformer with a demonstrated noise floor...

There has been important progress in understanding ecological dynamics through the development of the theory of ecological stoichiometry. For example, modeling under this framework allows food quality to affect consumer dynamics. While the effects of nutrient deficiency on consumer growth are well understood, recent discoveries in ecological stoichiometry suggest that consumer dynamics are not ...

The slanted-edge method specified in ISO Standard 12233, which measures the modulation transfer function (MTF) by analyzing an image of a slightly slanted knife-edge target, is not robust against noise because it takes the derivative of each data line in the edge-angle estimation. We propose here a modified method that estimates the edge angle by fitting a two-dimensional function to the image ...
