Keeping anaesthetic pollution to minimum in theatre environment

Anaesthetic gases and vapours are a potential pollutant in veterinary practices, with a prolonged lifetime of up to 120 years in the atmosphere. They impact not only on ozone depletion and, consequently, on global warming, but also on the health of operating theatre staff. In 2014, 2 of the 30 human adverse events reported involving veterinary surgeons and veterinary nurses in the UK were due t...

Pollution control caching

POLLUTION CONTROL CACHING The bandwidth mismatch of today's high speed processors and standard DRAMS is between a factor of 10 to 50. From 1995 to the year 2000 this mismatch is expected to grow to three orders of magnitude, necessitating greater emphasis for on-chip caches. However, the cost of on-chip memory is largely a function of the chip area it requires. Today, these on-chip caches typic...

Groundwater Pollution Control

Groundwater is an important source of potable water because it is abundant and readily available in many locations and often requires little or no treatment. In 1995, groundwater accounted for approximately 20% of potable water use in the U.S., and approximately 50% of the U.S. population relied on groundwater for their source of drinking water. In most European countries, groundwater accounts ...

: Functional Safety of a Theatre Stage Machinery Control System

Computer technology has the potential to significantly reduce the risks associated with scenery motion in live theatre, as well as enhancing the spectacle of performance. The industry is becoming more concerned about safety standards compliance. IEC 61508 is emerging as the universally favoured standard for functional safety of stage machinery control systems.
