Concept design overview: a question of choices and compromise.

The Spherical Tokamak for Energy Production (STEP) programme hypothesizes that a compact machine offers a route to reduced capital cost that directly tackles the barrier to entry of this potentially transformative technology. History has shown that with an unsolved, complex and highly interdependent design challenge, there is a need to balance exploration of the problem with progress. Almost all complex systems arise from the evolutionary improvement of simpler systems which is an approach the programme has adopted by working through a virtual natural selection of design families towards a single concept consistent with the initiating hypothesis.

Surveillance of bacterial disease in wartime Ukraine.

This analysis considers circulation of bacterial disease in wartime Ukraine. Anthrax, brucellosis, botulism and tularaemia are all naturally occurring in the country. The causative agents of these diseases also formed components of the biological weapons programme the Russian Federation inherited from the Soviet Union at the end of the Cold War.

Mental Health Nurses' Experiences of Working in the Emergency Department of Two Rural Australian Settings.

Providing effective mental health care in Emergency Departments (ED) is a fundamental expectation, as EDs increasingly become the first point of contact with health services for people in mental distress. As part of a larger multi-site translational research project this study explored the experiences, perspectives and recommendations of mental health liaison nurses (MHLN) employed in the EDs of two rural hospitals in New South Wales, Australia. Participants identified numerous benefits associated with embedding the MHLNs within the ED team.
