Asbestos has been described as a physical carcinogen in that long thin fibers are generally more carcinogenic than shorter thicker ones. It has been hypothesized that long thin fibers disrupt chromosome behavior during mitosis, causing chromosome abnormalities which lead to cell transformation and neoplastic progression. Using high-resolution time lapse(More)
We have presented data that indicate that MAP-2 associates with brain microtubules at nonrandomly distributed sites, whose distribution on the microtubule polymer can best be described by the 12-dimer MAP superlattice originally described by Amos; because of the additional spacings, however, between MAP-2 projections observed on MAP-2-saturated(More)
Organization of kinetochore fiber microtubules (MTs) throughout mitosis in the endosperm of Haemanthus katherinae Bak. has been analysed using serial section reconstruction from electron micrographs. Accurate and complete studies have required careful analysis of individual MTs in precisely oriented serial sections through many (45) preselected cells.(More)
A dichotomy exists in the engineering design process between 1) product teams organized to engineer products collaboratively, and 2) the single-user architectures inherent in computers and computer-aided design applications (CAx). Selective design authority is typically assigned to individuals within a product team; they become contributors in a serialized(More)
This thesis has been read by each member of the following graduate committee and by majority vote has been found satisfactory. As chair of the candidate's graduate committee, I have read the thesis of Tyson Baker in its final form and have found that (1) its format, citations, and bibliographical style are consistent and acceptable and fulfill university(More)

As chair of the candidate's graduate committee, I have read the thesis of Jonathan Knighton Shelley in its final form and have found that (1) its format, citations, and bibliographical style are consistent and acceptable and fulfill(More)
The engineering design process evolves products by a collaborative synthesis of specifications, personnel and organizations. Unfortunately, collaborative effectiveness is thwarted by existing single-user computer-aided applications like computer-aided design, computer-aided analysis, and others. These applications and associated file management systems(More)
