Wear behaviours

This study aims to test the effectiveness of an awareness-raising model designed based on the theory of planned behaviour regarding helmet use for motorcycle taxi drivers. This quasi-experimental study took place in the cities of Parakou (intervention group) and Porto Novo (control group).

Research protocols regarding the use of ActiGraph wGT3X+ accelerometers in care home residents are yet to be established. The purpose of this study was to identify the minimal wear time criteria required to achieve reliable estimates of physical activity (PA) and sedentary behaviour (SB) in older care home residents.

Highly porous Ti matrix composites can be a solution for some of the major clinical concerns for the load bearing implants such as low tribocorrosion resistance, stress shielding, and lack of biological anchorage. In order to respond to these needs, highly porous Ti-TiB-TiNx in-situ composites were synthesized by pressureless sintering using BN as reactant and urea as space holder. Corrosion behaviour was investigated at body temperature, in phosphate buffer saline solution (PBS), by measuring open circuit potential (OCP) and cyclic polarization.

Retrieved metal-on-metal acetabular cups are valuable resources in investigating the wear behaviour of failed hip implants, but adequate methods to do so are lacking. To further contribute to addressing this issue, we developed a method to detect the in vivo location of the primary wear scar of an explanted cup.

The feedback produced by operating Sodium-cooled Fast Reactors (SFRs) has shown the importance of material tribological properties. Where galling or adhesive wear cannot be allowed, hardfacing alloys, known to be galling-resistant coatings, are usually applied on rubbing surfaces.

The authors investigate friction and wear behaviours of atomic smooth graphite flake slides on hydrogenated diamond-like carbon (DLC). In this paper, the authors propose a novel method to examine if surfaces possess wear-resisting characteristic at micro-scale by measuring frictional force after a number of sliding cycles.

In those situations where an individual will have visitors in the home, refuses to wear a mask or cover his/her mouth when coughing, and/or is less likely to adhere to an anti-TB treatment regimen because of drug or alcohol addiction, it may be prudent to be more conservative and keep the patient in the hospital until sputum is AFB smear-negative. The individual may be transferred to another facility while still AFB smear positive, as long as it is to an AII room. The individual should be transported with appropriate respiratory precautions....

A Roman slave, identified by the tablet he wears around his neck, shows the family a basin with a base made in the form of the sea monster Scylla. The basin in the painting references an ancient basin (labrum) that was mounted onto a modern base similar to the one in the painting. Alma-Tadema included detailed references to Greek and Roman antiquities in many of his works of art. His paintings of domestic life set in ancient Rome appealed to the nineteenth-century public’s infatuation with Greek and Roman culture that was fueled by the rediscovery and excavations of Pompeii and Herculaneum.

In a study of the impact of dividend and earnings on stock prices, Hartone (2004) argues that a significantly positive impact is made on equity prices if positive earnings information occurs after negative dividend information. Also, a significantly negative impact occurs in equity pricing if positive dividend information is followed by negative earning information. Docking and Koch (2005) discovers that there is a direct relationship between dividend announcement and equity price behavior.
