Camera Arrangement Optimization for Workspace Monitoring in Human-Robot Collaboration.

Human-robot interaction is becoming an integral part of practice. There is a greater emphasis on safety in workplaces where a robot may bump into a worker. In practice, there are solutions that control the robot based on the potential energy in a collision or a robot re-planning the straight-line trajectory.

Increased livestock weight gain from improved water quality in farm dams: A cost-benefit analysis.

Access to water is a critical aspect of livestock production, although the relationship between livestock weight gain and water quality remains poorly understood. Previous work has shown that water quality of poorly managed farm dams can be improved by fencing and constructing hardened watering points to limit stock access to the dam, and revegetation to filter contaminant inflow. Here we use cattle weight gain data from three North American studies to develop a cost-benefit analysis for the renovation of farm dams to improve water quality and, in turn, promote cattle weight gain on farms in south-eastern Australia.

[The significance of plasmapheresis in the treatment of acute liver failure].

The authors describe the use of plasmapheresis in the treatment of acute hepatic failure in viral hepatitis with a fulminant course. Plasmapheresis was used with regard to severe trombocytopenia and manifestations of haemorrhagic diathesis. In the discussion they draw attention to the importance of supportive methods in the treatment of acute hepatic failure and to perspectives of liver transplantations in this context.
