As a result the estimated alphas and loadings in standard linear models(More)
The climate of the early nineteenth century is likely to have been significantly cooler than that of today, as it was a period of low solar activity (the Dalton minimum) and followed a series of large volcanic eruptions. Proxy reconstructions of the temperature of the period do not agree well on the size of the temperature change, so other observational(More)
The purpose of this study was to document mean, standard deviation, and range of furcation depth and Interroot separation dimensions of 5 multirooted tooth types. A total of 412 extracted teeth were examined and classified as: maxillary first molar, maxillary second molar, maxillary first premolar, mandibular first molar, and mandibular second molar. The(More)
The response of the head to impact in the posterior-to-anterior direction was investigated with live anesthetized and post-mortem primates. The study was conducted at the University of Michigan Transportation Research Institute (UMTRI) under the sponsorship of the Motor Vehicle Manufacturers Association. 3-D motion and epidural pressures were experimentally(More)
