Potential hearing compensation cost by race and sex.

A large general industrial population (n = 10,000) is analyzed using different low fences (15 bB HTL to 35 dB HTL) with the high fence held constant at 93 dB HTL. Three different audiometric test frequency combinations are considered: HTL.5,1,2 kHz, HTL.5,1,2,3 kHz and HTL1,2,3 kHz. The data base is analyzed first as a total population and then divided into different subpopulations including male, female, black and whites; and further subdivided into black males, black females, white males and white females. The findings indicate that significant differences exist between the groupings with respect to the potential hearing compensation cost and percent of a population exceeding the different low fence frequency combinations.

The sub-structure of nucleosomes.

A model for the sub-structure of the core particle of the nucleosome in chromatin, based on results from neutron and x-ray scattering and other physico-chemical observations, is presented. Two disc-shaped heterotypic tetramers of histones, opposed face-to-face, form the core protein. Each tetramer is enclasped by an annulus of DNA and the two annuli are joined by a linker piece. The mode of self assembly of core particles in solution is derived as are the changes in conformation of the core particle which occur on transcription and chromosome replication.

Coronary care unit ST-trending system: interpreting complex output data.

Analysis of the ST segment is an accepted part of the assessment of coronary ischaemia. Traditionally, such analysis has been applied to 12-lead surface electrocardiograms, but it is increasingly applied to 24-hour Holter recordings and bedside monitoring systems, using complex computer algorithms. There is a potential for results to be misleading as a consequence of uncritical acceptance of complex medical data processing.
