Symptomatic patients who are found to have nonspecific BWT on CT should undergo definitive endoscopic investigation because the majority will have significant gastroenterologic disease, and only a minority will have a normal colonoscopy.

Balloon-expandable aortic valves have excellent rates of circularity with low eccentricity and maintain full expansion without stent fracture at an average 2.5 years after implantation.

This paper describes the motivation, proposal, and early prototype testing of a computer tool for story visualisation prior to storywriting. An analysis of current software for making various types of visual story is made; this identifies a gap between software which emphasises preset banks of artwork, and software which emphasises low-level construction and/or drawing. A proposal is made to fill this gap, and a prototype implementation of the proposal is described in the context of a school-based study with Year 5, covering ages 9-10 years. Results from this prototype study both validate the novel proposal made and demonstrate that children are capable of more complex graphical interaction than most current software permits.

This paper reports a study assessing a new computer tool for cartoon storytelling, created by the authors for a target audience in the upper half of the English and Welsh Key Stage 2 (Years 5 and 6, covering ages 9 to 11 years). The tool attempts to provide users with more opportunities for expressive visualisation than previous educational software; its design was motivated by earlier work connecting "moving image literacy" with print literacy, and it was used here in storywriting preparation work: users first visualised a known story, then wrote their versions of it based on the cartoons they had made. The stories produced are compared with stories written using two other preparation activities, one a pencil-and-paper cartooning exercise and the other a teacher's normal planning session, which also resulted in a retelling of a known story.The study finds that no one preparation process had a noticeably different effect on the final written stories; however, the cartoons produced with the software are found to be quite different to their paper counterparts, showing a greater variety of character action, pose and interaction, slightly more variety of camera shot distance, and more pictures. Children's and teachers' reactions to the software tool are also discussed.
