UNLABELLED The purpose was to illustrate the variability of hormonal contraception of patients that presented with membranous dysmenorrheal. A case analysis chart review was completed on six patients referred to a Pediatric Gynecologist in an academic setting. In each case the patient underwent a thorough pelvic and bimanual exam. Following the initial presentation, each patient continued to be...

Thirty-two children with femoral shaft fractures were treated conservatively with initial skin traction followed by an additional period in a spica cast. After 12 to 20 months of follow up, none had any pain and all of them were attending school without problems. Shortening of more than 2 cm occurred in 6 (19%) of the 32 patients. The most important factor associated with shortening was an over...

In the context of mine warfare, detected mines can be classified from their cast shadow. A standard solution is to perform image segmentation first, and then to extract a set of features from the shape allowing classification in a final step. In this paper, we extend this procedure to a sequence of images obtained along a part of a circular trajectory of the sonar. For a given ground mine excep...

In this article we give a survey of the current practice and state-of-theart of recommender services in scientific digital libraries. With the notable exception of amazon.com and CiteSeer which do not qualify as proper scientific libraries our survey revealed that in scientific libraries recommender services are still not in wide use – despite the considerable benefits they offer for students a...

Scientific digital library systems are a very promising application area for value-added expert advice services. Such systems could significantly reduce the search and evaluation costs of information products for students and scientists. This holds for pure digital libraries as well as for traditional scientific libraries with online public access catalogs (OPAC). In this contribution we first ...

Multiple choice questions are a convenient and popular means of testing beginning students in programming courses. However, they are qualitatively different from exam questions. This paper reports on a study into which types of multiple choice programming questions discriminate well on a final exam, and how well they predict exam scores.

A mechanical digitizer was developed for use in prosthetics research where measurements of small differences in shape are of interest. Root-mean-square error was 0.075 mm in the radial direction, 0.05 degrees in the tangential direction, and 0.1 mm in the vertical direction. The system has potential use for time-dependent assessment of changes in socket and residuum cast shape, assessment of so...
