The Wheel Keeps Turning

The big wheel keeps on turning.

The wheels on the bus go round and round, round and round, round and round, all day long. Those of you who have children know this song. It's great. At least, it is for the first 10 times of listening. In the same way, some have welcomed reorganisations of the National Health Service (NHS) as the way forward – but again, and again, and again, year in, year out? My first experience of primary ca...

Atlantic circulation keeps turning

Two major research projects that are running out in November have investigated the Atlantic circulation system that includes the Gulf Stream and come to the conclusion that there is no immediate risk of it shutting down, allaying fears that were raised seven years ago. Yet a better understanding of the interaction between ocean circulation and climate change is still needed, so two new research...

The Turning of the Wheel

Home haemodialysis in Australia - is the wheel turning full circle?

In the mid 1970s, home haemodialysis accounted for nearly half of all patients on dialysis, both in Australia and elsewhere. The advent of both peritoneal dialysis (itself a home therapy) and satellite haemodialysis resulted in a gradual attrition in the use of home haemodialysis. Since 2000, the introduction of nocturnal home haemodialysis has begun to change this pattern in Australia, with a ...

Analysis of 3D Passive Walking Including Turning Motions for the Finite-width Rimless Wheel

The focus of studies in the field of passive walking has often been on straight walking, while less attention has been paid to the field of turning motions. In this paper, the passive motions of a finite width rimless wheel as the simplest 3D model of passive biped walkers was investigated with a focus on turning motions. For this purpose, the hybrid model of the system consisting of continuous...
