RESUMO
Kondrashov and Rothenberg (Appl. Radiat. Isot. 55 (2001) 799) have published "a substantial correction for calculating estimates of lead concentration and uncertainty for in vivo X-ray fluorescent bone analysis with Cd-109 source" (sic). Our paper shows that their correction fails to consider two important points that render it (i) a correction to a superseded method and (ii) of limited effect. Also, their approach to a "crude" estimate produces measurement uncertainties that are implausibly small. In order that they not be propagated in the literature, our paper also corrects several misstatements and errors in Kondrashov and Rothenberg.

As part of an ENB educational evaluation of teamworking in mental health, a report-and-respond survey was used as one of five data collection methods. This instrument disseminated earlier findings back to the participants and invited further comments. This article discusses the usefulness of this type of survey as a data collection tool and presents the findings of the survey which was administered to service professionals, educationalist, students, users and carers involved in mental health throughout England. The findings show that when groups of professionals are working within increasingly tight financial constraints and increased workloads, multiprofessional teamworking can be scarce in reality. These tensions present issues for nurse education and training at both pre- and post-registration levels in relation to the teaching of, for and about effective teamwork.

The aluminum industry has experienced several fire losses involving hot rolling mills. These accidents have resulted in up to 10 million of dollars in damages, lost production and injuries. The problems contributing to the losses include operations, equipment, building and technical issues. This paper reviews datails of these large losses and the impact they had on the industries where they occurred. A review will then be made of the elements at the plant which contributed to the event and an engineering study which quantified the hazard and demostrated the effectiveness of various control measures in preventing this type of event at other plants. solutions included a combination of traditional fire protection systems and coordination with operations for effective hazard control (AU)
