AIM This study aimed to evaluate whether the extract of Morinda citrifolia L. mixed with irreversible hydrocolloid powder decreases microbial contamination during impression making without affecting the resulting casts. MATERIALS AND METHODS Twenty volunteers were randomly divided into two groups (n = 10). Group A 30 ml extract of M. citrifolia L diluted(More)
A subset of ultraluminous X-ray sources (those with luminosities of less than 10(40) erg s(-1); ref. 1) are thought to be powered by the accretion of gas onto black holes with masses of ∼5-20M cicled dot, probably by means of an accretion disk. The X-ray and radio emission are coupled in such Galactic sources; the radio emission originates in a relativistic(More)
Effective traffic incident management is an important success factor in reducing incident duration and the severe resultant congestion impacts. As such by having proper and reliable traffic incident indicators can greatly improve prioritisation and deployment of effective rapid incident response. This research aimed to examine and improve indicators for(More)
A structured approach is required to ensure significant and ongoing improvement in traffic systems strategy and operations. A review of improvement frameworks identified the Capability Maturity Model as a potentially useful approach to assess the current level of 'capability' of traffic management systems and identify future trajectories in the short to(More)
Assessing and prioritising cost-effective strategies to mitigate the impact of traffic incidents on non-recurrent congestion on major roads are currently a major challenge for road network operations. There is a lack of relevant local research in this area. Several incident duration models developed from international research are not considered appropriate(More)
Millisecond radio pulsars are neutron stars that have been spun-up by the transfer of angular momentum during the low-mass X–ray binary phase. The transition from an accretion-powered to a rotation-powered pulsar takes place on evolutionary timescales at the end of the accretion process, however it may also occur sporadically in systems undergoing transient(More)
