Denis Keefeavoured the dispersion and the cosmopolitanism of the floras and tetrapod faunas. In turn, Triassic successions are rarely complete, commonly showing depositional hiatuses that hinder the correlation among the different basins. Besides, endemism of land vertebrate assemblages may also be due to faci

B. B. Godfrey,T. P. Hughessafe and economic manner. Dynamic stress/strain information can be calculated if the loading and restraining conditions are known, but these are only useful if a simple model is available to mirror these factors. In practice these simple solutions are seldom available. The alternative approach is to

J. M. Buzzirules is the method of design based on prior experience, rather than by structural mechanics. In design-by-analysis, stress analysis plays a central role [.]. It is not a new concept in mechanical engineering, since such a concept arose in railroad engineering, and then was adopted in automotive, an
