Can Law Improve Prevention and Treatment of Cancer?

The December 2011 issue of Public Health (the Journal of the Royal Society for Public Health) contains a symposium entitled: Legislate, Regulate, Litigate? Legal approaches to the prevention and treatment of cancer. This symposium explores the possibilities for using law and regulation – both internationally and at the national level – as the policy instrument for preventing and improving the treatment of cancer and other leading non-communicable diseases (NCDs). In this editorial, we argue that there is an urgent need for more legal scholarship on cancer and other leading NCDs, as well as greater dialogue between lawyers, public health practitioners and policy-makers about priorities for law reform, and feasible legal strategies for reducing the prevalence of leading risk factors. The editorial discusses two important challenges that frequently stand in the way of a more effective use of law in this area. The first is the tendency to dismiss risk factors for NCDs as purely a matter of individual \u27personal responsibility\u27; the second is the fact that effective regulatory responses to risks for cancer and NCDs will in many cases provoke conflict with the tobacco, alcohol and food industries. After briefly identifying some of the strategies that law can deploy in the prevention of NCDs, we briefly introduce each of the ten papers that make up the symposium

The influence of process gas type on the enamel surface condition of a high power diode laser generated single-stage ceramic tile grout seal

Almost all laser materials processing operations require the simultaneous use of an process or assist gas. This paper examines the use of O2, Ar, N2 and He as process gasses during the firing of a vitreous enamel to form a single-stage ceramic tile grout seal with a high power diode laser (HPDL) and the effects thereof on the surface condition of the glaze. The findings revealed marked differences in the surface condition of the HPDL generated enamel glaze depending upon the process gas used. The use of O2 as the process gas was seen to result in glazes with far fewer microcracks and porosities than those generated with any of the other three gasses, particularly He. Such differences were found to be due to the ability of the smaller O2 gas molecules to dissolve molecularly into the open structure of the HPDL generated enamel glaze and also, the inherent reactiveness of O2 which consequently effects exothermic reactions when it is used as a process gas. Both occurrences were seen, in turn, to affect the cooling rate and therefore the tendency of the molten glaze to generate microcracks when cooled

A comparative investigation of the wear characteristics of a high power diode laser generated single-stage tile grout and commercial epoxy tile grout

A comparative study of a single-stage ceramic tile grout, generated using a 60 W high power diode laser (HPDL), and a commercially available tile grout has determined the wear characteristics of the two materials. Within both normal and corrosive environmental conditions, the single-stage ceramic tile grout proved to have a superior wear rate over the epoxy tile grout, 0.9 mg/cm2/h compared with 125 mg/cm2/h when in an HNO3 environment respectively. Likewise, life assessment testing revealed that the single-stage ceramic tile grout gave an increase in wear life of 4 to 42 times over the commercially available epoxy tile grout, depending upon the corrosive environment. It is believed that the economic and material benefits to be gained from the deployment of such an effective and efficient means of sealing ceramic tiles could be significant
