Construction needs cloud flexibility
Australia’s embattled construction sector could benefit from cloud based information systems that can be switched on and off in lockstep with individual projects – with the exception of those organisations based in remote areas like the Kimberleys.

A research team from the University of Leicester and a Singapore medical-tech company has developed a blood-pressure device that provides more accurate blood pressure readings that old-fashion devices. And, you wear it like a wrist watch.
Funded by the Department of Health in the United Kingdom, the device is designed to provide a very accurate way to measure blood pressure using the largest artery in the body.
The device, which is worn like a wrist-watch, is placed over the radial artery on the wrist.
A sensor then measures the artery's pulse and sends the reading into a computer that electronically measures blood pressure in the aorta, the largest artery in the human body.
Traditional blood-pressure measuring devices, which are wrapped around the upper arm, measure the pressure in an artery that is a further distance from the heart than the artery used by this new device.
The aorta is relatively close to the heart, so this new device measures blood pressure that is much closer to the heart (and the brain) than the old pressure devices, which have been used for decades.
Consequently, the new wrist-watch device provides a much more accurate picture of blood pressure than the older technique.
