The need to make emergency drills as realistic as possible presents problems in children's hospitals because of the difficulties that exist in recruiting and using children to act as casualties. In this article, the author describes one approach, the use of home school children and their parents, that proved highly successful in conducting a drill involving a school bus accident and possible ch...

Existing computer-assisted instructional (CAI) techniques for introductory biology are presently restrictive in scope, due to their focus on utilizing drills that aim for rote memorization instead of providing interaction that aids in intuitive understanding. In this paper, we discuss a prototype system for assessing learner understanding of introductory cell biology concepts using sketch-based...

A “skills and drills” intervention in 4 hospitals in Karnataka, India, produced modest improvement in provider knowledge and skills but not in actual response to obstetric and newborn emergencies. We explore possible explanations, which include (1) the need for a more intensive intervention; (2) other weaknesses in the health system; and (3) behavioral or organizational barriers related to hier...

High-frequency and high-speed printed circuit boards (PCBs) are made of ceramic particles anisotropic fibres, which difficult to machine. In most cases, severe tool wear occurs when drilling high-frequency PCBs. To protect the substrate drills, diamond films typically fabricated on drills using hot filament chemical vapour deposition (HFCVD). This study investigates coating characteristics with...
