A technique for finding the symmetry axes of implicit polynomial curves under perspective projection.

This paper presents an algebraic technique for detecting the symmetry axes of a perspectively projected plane curve. The procedure applies to implicit polynomials which has been fitted to 2D image data acquired by means of a photo camera or a TV set. The effectiveness of the proposed method has been demonstrated experimentally by using both synthetic and real images.

[Anesthesia problems in children with cleft lip, maxilla and palate].

The technical and physiopathological problems associated with labiomaxillopalatine schisis in children are discussed. Personal experience, involving the choice of a type of anaesthesia based on the use of an analgesic (pentazocine), and the exclusion of halogenated anaesthetics in most cases, is reported. Stress is laid on the simplicity of the technique.

[Catamnestic study of 92 cases of burned patients: medico-legal considerations].

The authors have examined 1478 burned or scalded patients of the Plastic Surgery Institute of the University of Parma from 1967 to 1976; they have considered particularly 92 cases who showed more than 20% of burned skin. For these patients they have considered many data of medico-legal interest in order to facilitate the estimate of the personal damage in penal and civil law.

[Clinico-statistical data on 1,478 cases of burns admitted to the Burn Center of the Plastic Surgery Institute of the University of Parma in the 10-year period of 1967-76].

After having shortly illustrated the work's purpose, the Authors start to examine the statistics obtained in a research developed on 1,478 burned patients admitted at the burn center of the Institute of Plastic Surgery of Parma's University from 1967 to 1976. By and by are taken into consideration the statistics concerning age, sex, work, the percentage of burned body surface, the burn's causes, the mortality due to burns and the time spent in hospital. The most important data are those that come out from the comparison of the data that the N.
