Abstract This paper presents an approach for the optimisation of geological disposal canister loadings, combining high resolution simulations used nuclear fuel characteristics with articial neural network and a genetic algorithm. The fuels (produced in open cycle without reprocessing) considered this work come from Swiss Pressurised Water Reactor, taking into account their realistic lifetime re...

Type 304L stainless steel (304LSS) is one of the candidate canister materials for storing radioactive spent fuels, usually near seashore environments along with nuclear power plants. During prolonged exposure dry storage canisters to saline environments, they are highly susceptible chloride induced stress corrosion cracking. Failure a not only would release isotopes into environment, but also l...

The profiles of major volatile organic compound (VOC) sources in petrochemical industry of the Yangtze river delta, China, were experimentally determined. Source samples were taken using summa canister near the petrochemical units. The concentrations of 72 VOC species were quantified using canister sampling and a gas chromatography–mass spectrometry system, and VOC source profiles were develope...

If the anaesthetic circle system is arranged to increase the humidity of fresh anaesthetic gases by placing the carbon dioxide absorbent canister between the fresh gas inlet and the patient, drying of the soda-lime can occur. Very dry soda-lime adsorbs significant quantities of halothane. Using fresh soda-lime, effluent halothane concentration reached 50% of the input concentration in 35s, but ...

A 30-year-old male was presented to the Emergency Department (ED) by the Emergency Medical Services (EMS). He was found unconscious but breathing normally, and had a seizure for more than 30 minutes. He was no previous history of systemic disease, previous operation, medication and any known allergy. According to the witnesses, he was alone in the coffee shop, and besides him was a lighter refi...

One of the requirements of a system for disposal of spent nuclear fuel is that it should be possible and feasible to retrieve the canisters even after they have been put in place and the surrounding bentonite has absorbed water and developed a swelling pressure. This ‘gripping’ of the canister must be released before the canister can be retracted from the deposition hole. One way to achieve thi...

The metered-dose inhalers (MDIs) currently available for inhaled Background: corticosteroid delivery do not offer an integrated dose counter; therefore, it is difficult to evaluate adherence of patients. The present authors developed a linear regression equation using canister weight to calculate the number of doses actuated from the MDIs. This study aimed to assess medical adherence after the ...
