YREC: The Yale Rotating Stellar Evolution Code

The stellar evolution code YREC is outlined with emphasis on its applications to helio- and asteroseismology. The procedure for calculating calibrated solar and stellar models is described. Other features of the code such as a non-local treatment of convective core overshoot, and the implementation of a parametrized description of turbulence in stellar models, are considered in some detail. The code has been extensively used for other astrophysical applications, some of which are briefly mentioned at the end of the paper.Comment: 10 pages, 2 figures, ApSS accepte

Work related road safety

Work-related road safety is increasingly regarded as a vital issue for a wide range of private companies. Vehicles used in the course of employment are a part of the workplace and it has been estimated that work related road crashes in Australia account for about half of all occupational fatalities and 15% of national road deaths. Further, fleet vehicles are generally sold to private buyers within a few years. This suggests that the safety of a company’s fleet vehicles and the road safety behaviour of its employees is paramount when considering the road safety of the general population. RACV commissioned this report to gain a better understanding of work related road safety. The project includes a review of vehicle technology and driver based safety initiatives; a review of currently available resources that address work related road safety and consultations with a range of organisations. The report concludes by outlining best practice principles and priority actions for managers to improve a company’s road safety profile.Martin Small, Trevor Bailey, Mary Lydon, Tim Davern, Melinda Congi
