Optimised Mix Design for Normal Strength and High Performance Concrete Using Particle Packing Method
BACKGROUND Failure to achieve properly localized, permanent tissue destruction is a common cause of arrhythmia recurrence after cardiac ablation. Current methods of assessing lesion size and location during cardiac radiofrequency ablation are unreliable or not suited for repeated assessment during the procedure. MRI thermography could be used to delineate permanent ablation lesions because tiss...
The concept of relative bid privacy in auction is proposed, which does not conceal the bids, but conceals the link between them and the corresponding bidders. Relative bid privacy leads to two advantages: the bidding values can be very precise and any auction rule can be applied. A new mix network is designed and applied to implement relative bid privacy efficiently. Two rounds of shuffling are...
In 14 mongrel dogs wash-in and wash-out curves for halothane were obtained from measurements of arterial blood, mixed venous blood and end-tidal gas. From a certain point in the wash-in period the halothane concentration of arterial blood can be calculated from the halothane concentration in end-tidal gas and the blood-gas partition coefficient for halothane. Analysis of the curves shows that t...
BACKGROUND We undertook a randomised, double-blinded, placebo-controlled, crossover trial to test whether intake of artificial food colour and additives (AFCA) affected childhood behaviour. METHODS 153 3-year-old and 144 8/9-year-old children were included in the study. The challenge drink contained sodium benzoate and one of two AFCA mixes (A or B) or a placebo mix. The main outcome measure ...
