Digital games and playful interactive installations are considered a promising means to raising awareness about the environment and persuading people to adopt an environmental friendly behavior. However, the selection and use of appropriate methods and paradigms for designing and evaluating such systems and successfully blending the ‘fun’ element with the messages to be communicated is still an...

Pharmacovigilance is “the science and activities relating to the detection, assessment, understanding and prevention of adverse effects or any other drug related problem”. There is criticism that drug safety reporting in medical research is inadequate. There is possibility of many types of bias in vaccine safety studies especially in the diagnostic process, at investigator level and in the proc...

It has been documented that AE signals propagate in thin plates as extensional and flexural plate modes. This was demonstrated using simulated AE sources (pencil lead breaks) by Gorman [1] on thin aluminum and gr/ep composite plates and by Gorman and Prosser [2] on thin aluminum plates. A typical signal from a pencil lead break source which identifies these two modes is shown in Figure 1. AE si...

Direct numerical simulation is used to investigate the nature and behaviour of steady spanwise flow modulations excited internally in the Blasius boundary layer, primarily for a Reynolds number based on the displacement thickness ( Æ ) greater than 1,600. Both types of disturbances known – -/streak-/Klebanoff modes or longitudinal vortex modes – exhibit a periodic spanwise variation, but the -m...
