Hygienic Quality of Foods Served on Aircraft

This study set out to evaluate the microbiological hazards associated with the foods served on aircraft. To identify the microbiological quality of hot and cold meals prepared worldwide, samples of aircraft meals were monitored for Salmonella between 1989 and 1994, and for indicator bacteria and Staphylococcus aureus, Bacillus cereus and Clostridium perfringens between 1991 and 1994.

Environmental epidemiologic investigations in the styrene-butadiene rubber production industry.

A review of the literature and an update that is in progress of a previous retrospective cohort mortality study of the styrene-1,3-butadiene industry are discussed. The follow-up has now been extended from April 1, 1976, through December 31, 1981, for plant B and December 31, 1982, for plant A. The person-years at risk of death have gone from 34,187 to 43,341 in plant A and from 19,742 to 26,31...

International Comparisons of Construction Industry Performance: Further Investigations

While there have been many attempts at comparisons of construction performance over the past 50 years, the results have generally been inconclusive and/or contradictory. Such comparisons are of great interest to industry, governments and theorists alike but there is little agreement as to how they are best done. A variety of methodologies have been used, however, the lack of satisfactory outcom...
