BACKGROUND This paper reports on health inequalities awareness-raising workshops conducted with senior New Zealand health sector staff as part of the Government's goal of reducing inequalities in health, education, employment and housing. METHODS The workshops were based on a multi-method needs assessment with senior staff in key health institutions. The(More)
Vertically aligned carbon nanotube turfs (VACNTs), consisting of entwined, nominally vertical carbon nanotubes, are being proposed for use as electrical and thermal contact materials. Issues in their implementation include high contact resistance, the van der Waals interactions of carbon nanotubes, and a low temperature limit during processing. One route(More)
Foreword Ma ¯ ori as a population group have, on average, the poorest health status of any ethnic group in New Zealand. The causes of this are complex, but much of this health inequality is linked to the uneven distribution of the determinants of health, such as income, housing, education and employment. As part of its day-today business, government and(More)
A facility to characterize microelectromechanical system (MEMS) thermal switches by measuring two pertinent figures of merit is described. The two figures of merit measured are the ratio of thermal resistance of the switch in the off and on states, Roff/Ron, and the time required to switch from the off to the on state, tauswitch. The facility consists of(More)
In this work a thermal interface material fabricated by thermocompression bonding of vertically aligned carbon nanotube turf (VACNT) to metallized substrates was characterized. The VACNT structure was fabricated onto silicon substrates using chemical vapor deposition. The structures were then transferred to metallized substrates using thermocompression(More)
