Hyperbaric Escape Systems (HES) are used when saturation diving bells have to be evacuated and divers transported to safety. The aim of the present investigation was to determine the levels of metabolic CO2 production expected from the occupants of an HES in different wave states, and from this, to recommend a reasonable and safe requirement for scrubbing CO2 within an HES. The CO2 production a...

For some time there has been wordwide concern for the health risks of cigarette smoking. In several countries, including the United States, Canada and the United Kingdom, surveys of the tar and nicotine delivered by commercial brands of cigarettes are carried out and published. Recently carbon monoxide levels have also been measured. The combustion of tobacco products such as cigarettes also pr...

Abstract Aim During surgical scrubbing, Sikhs in healthcare are often expected to remove their kara, a religious metal bangle. This seems inconsistent with policies permitting rings. As some feel they cannot do this, refused entry theatres. The aim of this quality improvement project is explore if and how exclusion might affect propose an inclusive solution accordingly. Method Working MedRACE (...

Background: Scrubbing with toothbrush and gargling chlorhexidine has been shown to be effective in reducing bacteria preventing ventilator-associated pneumonia (VAP) patients the intensive care unit (ICU). However, we still lack established evidencebased practice for oral specific ICUs.Objective: To evaluate effect of two practices different ICUs as measured by previously developed Intensive Ca...

This paper describes a laboratory-scale study on the use of recirculating cyclones as reaction chambers for dry scrubbing of gaseous HCl with solid slaked lime particles. This gas cleaning system combines a numerically optimized reverse flow gas cyclone (RS_VHE geometry) with a straight-through cyclone concentrator, which simultaneously increases the capture of the solid particles and promotes ...

We present an architectural framework for NModular Redundant (NMR) systems exploiting the dynamic partial reconfiguration capability of FPGAs. Partial reconfiguration is used to dynamically construct the throughput datapath under failure conditions. The throughput datapath utilizes only one instance of a Functional Element (FE) while the other instances undergo evaluation by being subjected to ...
