This article reports on a study examining the phenomenon of resilience, or the manifestation of competence despite the presence of stressful life events or circumstances, as a factor leading to the academic success of 20 African American 12th-graders (10 females, 10 males)from impoverished backgrounds. Interviews were conducted with these at-risk but achieving urban California high school seniors, to identify internal and external forces contributing to the development of resilience among...

An oral health care programme in secondary schools using the atraumatic restorative treatment (ART) technique for dental caries was started in 1993. Glass-ionomer was used as the restorative and sealant material. Sealants were placed using the ‘press finger’ technique. Results after 1 year revealed a survival percentage for one-surface ART restorations of 93.4 whilst the complete and partial retention percentages for sealants were 60.3 and 13.4, respectively. No caries was observed in teeth...

To characterize the early events in liver injury produced by halothane, experiments were performed in genetically susceptible guinea pigs 19 hours after halothane exposure. Serum bile acid concentrations were fourfold increased in halothane-exposed animals compared with controls. In isolated perfused liver experiments, livers from halothane-exposed animals did not differ in hepatic oxygen uptake or in perfusion pressure at the end of experiments, but bile flow and biliary bile salt...

General Circulation Models (GCMs) were used to develop climate change scenarios for the Lengwe National Park in Malawi Scenanos of future precipitation and ambient temperature were in turn used to evaluate habitat suitabihty of 5 ungulate populations and to rank their vulnerabihty to global climate change in the park Preliminary results suggest that ambient temperatures may n s e with a doubling of atmospheric COz, and precipitation will be more vanable The vulnerability assessment results...

Thirty-one students from a French rural engineering school spent a six-week training period in an isolated tropical forest environment in western Cote d'Ivoire. They received preventive medical treatment before departure and were kept under constant surveillance. Because the group was multiethnic and divided into four separate work teams, communication was a major problem. Regular prevention and continuous care allowed control of the fever episodes which occurred in one half of the group...
