Carbon Dioxide Reduction Systems

The Methoxy system for regenerating oxygen from carbon dioxide was studied. Experiments indicate that the reaction between carbon dioxide and hydrogen can be carried out with ease in an efficient manner and with excellent heat conservation. A small reactor capable of handling the C02 expired by three men has been built and operated. The decomposition of methane by therma1,arc and catalytic processes was studied. Both the arc and catalytic processes gave encouraging results with over 90 percent of the methane being decomposed to carbon and hydrogen in some of the catalytic processes. Control of the carbon deposition in both the catalytic and arc processes is of great importance to prevent catalyst deactivation and short circuiting of electrical equipment. Sensitive analytical techniques have been developed for all of the components present in the reactor effluent streams

Legal and Regulatory Implications of Disruptive Technologies in Emerging Market Economies

The is report was produced for the World Bank and looks at the legal implications which may impact on the introduction of disruptive technology in emerging markets

Aboriginal People ‘Talking Back’ to Policy in Rural Australia

How does a geographically remote Australian Aboriginal community ensure that culturally and locally important priorities are recognised in policy? This paper discusses a case study of Indigenous community engagement in policy making, revealing some of the challenges community leaders face and the strategies they implement in their struggle for a strong say and hand in designing appropriate policy responses to local problems. The case study community is Walgett, a remote New South Wales community with a large Aboriginal population, distinguished in history for its part in the 1965 Freedom Ride which highlighted racial segregation and discrimination across outback Australia. Today Walgett ranks as one of Australia’s most disadvantaged communities (Vinson, 2007), and hence was chosen as one of 29 priority remote Aboriginal communities to be the focus of the Australian Government’s Remote Service Delivery commitment, part of the Closing the Gap agenda

Policy, legal and regulatory implications of a Europe-only cloud

This article explores key legal and regulatory issues arising from recent cloud localization initiatives, with a particular focus on calls to establish a Europe-only cloud. The analysis covers jurisdictional conflicts and extraterritoriality concerns, as well as the impact on fundamental rights such as privacy, data protection and freedom of expression

Counting outdated honeypots: Legal and useful

Honeypots are intended to be covert and so little is known about how many are deployed or who is using them. We used protocol deviations at the SSH transport layer to fingerprint Kippo and Cowrie, the two most popular medium interaction SSH honeypots. Several Internet-wide scans over a one year period revealed the presence of thousands of these honeypots. Sending specific commands revealed their patch status and showed that many systems were not up to date: a quarter or more were not fully updated and by the time of our last scan 20% of honeypots were still running Kippo, which had last been updated several years earlier. However, our paper reporting these results was rejected from a major conference on the basis that our interactions with the honeypots were illegal and hence the research was unethical. We later published a much redacted account of our research which described the fingerprinting but omitted the results we had gained from the issuing of commands to check the patch status. In the present work we provide the missing results, but start with an extended ethical justification for our research and a detailed legal analysis to show why we did not infringe cybersecurity laws

Measurement of two-halo neutron transfer reaction p(11^{11}Li,9^{9}Li)t at 3AA MeV

The p(\nuc{11}{Li},\nuc{9}{Li})t reaction has been studied for the first time at an incident energy of 3$A$ MeV delivered by the new ISAC-2 facility at TRIUMF. An active target detector MAYA, build at GANIL, was used for the measurement. The differential cross sectionshave been determined for transitions to the \nuc{9}{Li} ground andthe first excited states in a wide range of scattering angles. Multistep transfer calculations using different \nuc{11}{Li} model wave functions, shows that wave functions with strong correlations between the halo neutrons are the most successful in reproducing the observation.Comment: 6 pages, 3 figures, submitted to Physical Review Letter

Lifetimes of states in 19Ne above the 15 O + alpha breakup threshold

The 15O(alpha,gamma)19Ne reaction plays a role in the ignition of Type I x-ray bursts on accreting neutron stars. The lifetimes of states in 19Ne above the 15O + alpha threshold of 3.53 MeV are important inputs to calculations of the astrophysical reaction rate. These levels in 19Ne were populated in the 3He(20Ne,alpha)19Ne reaction at a 20Ne beam energy of 34 MeV. The lifetimes of six states above the threshold were measured with the Doppler shift attenuation method (DSAM). The present measurements agree with previous determinations of the lifetimes of these states and in some cases are considerably more precise
