The analysis of variance results indicated that the footwear material, floor, contamination conditions, and groove width were all significant (p<0.0001) factors affecting the measured COF.
Friction measurements were conducted to study the effects of shoe sole, floor, contamination, and inclined angle of the floor surface on friction coefficient.
A regression model using measured COF as the dependent variable and tread groove width, groove orientation, footwear material, floor, and contamination conditions as independent variables was established.
The results showed that all the footwear materials, floors, and the contamination conditions affected the measured COF significantly.
In this study, friction measurements using a Brungraber Mark II slipmeter were conducted under three footwear materials, three floors, and three contamination conditions.
We also observed that the steepest increase in BLLs occurred at the lowest levels of lead-contaminated floor dust, which indicates that lead contamination should be kept as low as possible.
A Delaware bankruptcy judge held a hearing in September on whether plaintiffs' evidence on asbestos contamination from floor tiles had scientific validity, and concluded last month that the evidence was not admissible.
Two studies, the first of their kind to use nationally representative data from U.S. homes, predict how varying degrees of lead contamination of floor and windowsill dust may affect the blood lead levels of resident children [ EHP 117:461–467; Gaitens et al.; EHP 117:468–474; Dixon et al.].
Plastic overshoes may increase bacterial contamination of floors [ 13] and, in addition, hands become contaminated when overshoes are put on or removed.
But before Cambridge's social and political scientists moved into the Old Cavendish, in 1976, the National Radiological Protection Board went into Rutherford's room and reported contamination on the floor and on doors, handrails and shelves.
Virus was shed by all four inoculated ducks and transmitted to all four contact ducks either through direct contact or environmental contamination of the floor and shared pool (Table 1).
