The objective of this study was to examine the effects of the hydroxyapatite (HA) reinforcement morphology and content on the fatigue behavior of HA reinforced high density polyethylene (HDPE). To this end, HDPE was reinforced with 20 and 40 vol% of either HA whiskers or an equiaxed HA powder, and tested in four-point bending fatigue under simulated physiological conditions. The fatigue life, m...

Jacketing of reinforced concrete columns is a common and useful strengthening method. This method substantially improves mechanical properties of the column, such as flexural strength as well as shear and ductility. In this paper, the behavior of confined reinforced concrete columns are investigated. The results indicate that the method is more effective for slender columns in the region of the...

As social media features are increasingly added to e-learning, we urgently need more case studies of their use to ground practices in actual experience rather than hype. Using ethnography-based approach, we studied five continuous professional development pilot trainings where learning largely took place at workplace through wikis, blogs, forums, chats and voice conferencing. Learners valued in...

Fourteen pigs underwent left-sided hepatectomy. The resection was performed with a linear stapling device and the pigs were randomised to either Surgicel reinforced resection lines or not. The median time required for resection was 25 min (range 17-30) in the Surgicel reinforced group compared to 30 min (range 21-41) in the stapled group. This difference was, however, not statistically signific...

T he world’s press frequently contains stories of failed rehabilitation attempts [1] by media personalities, and popular songs on this topic can galvanize strong views [2]. Such events highlight the popularisation of a faulty view that rehabilitation offers only a marginal opportunity for benefit and as such should be avoided at all costs. It is unclear if such scepticism, reinforced by the med...

Public concern about the environment can be unpredictable because it is influenced by numerous factors. Environmental health issues often emerge as important because the public is worried about their health especially when it comes to cancer. Public fear of cancer from environmental exposures is reinforced by many of the US regulations that set pollutant limits based on reducing the risk of can...

This article argues that the increasing use of press images around 1900 contributed to construction political persona British Statesman Joseph Chamberlain. These fused scenes from his public and private life and, paradoxically, new focus on characteristics reinforced role. His did not replace side, nor was unrelated politics as celebrity scholarship suggests, but these projected widened scope w...
