RESUMO
In remote field localities, given limited access to specialized equipment, determining the sex of captured adult varanid lizards before release can be problematic. Determining the sex of the tropical semiaquatic Varanus mertensi, a species with significant tail musculature, is difficult using traditional hand-pressure-induced hemipenile eversion. As an alternative, we propose an extended technique for identifying the sex of adult V. mertensi. We recommend using a combination of the traditional field-based hemipenile eversion technique and a measurement of the ratio of androgens to estradiol in plasma samples taken from field-captured animals.

A case of peritonitis caused by Flavimonas oryzihabitans (Pseudomonas oryzihabitans; CDC group VE-2) in a patient on continuous ambulatory peritoneal dialysis is reported. This is the seventh case of infection caused by this organism reported in the English literature and the third reported case of continuous ambulatory peritoneal dialysis-related peritonitis caused by this organism; it is the first case of infection of any kind caused by this organism in England.

The method of lines is a numerical technique particularly suited to the solution of parabolic partial differential equations, which has been the subject of much research in recent years, and which has been incorporated into a number of readily available computer library packages. The method has been applied to a number of problems in areas such as chemical engineering, atmospheric physics and nuclear engineering. It does not however, seem to have been widely used in biological mass transfer problems of the type arising in the study of artificial lungs and kidneys. By describing some of the problems tackled by the author and his colleagues, it is hoped to interest a wider audience in the potential benefits of this method.
