The application of the effective stress analysis to earth slopes has suffered through lack of a general solution such as that presented by Taylor (1937) for the total stress analysis. Recent developments in computing technique have been applied to the slip circle method and have made it possible...
Stability charts are presented to facilitate the computation of the factor of safety of earth slopes during rapid drawdown. As the reservoir level is lowered, the factor of safety decreases if it be assumed that no dissipation of pore pressure occurs during drawdown. Pore pressures during...
Within the framework of limit equilibrium methods of stability analysis, no restriction need be placed at the outset upon the shape of the possible slip surface. In many cases, the critical surface may deviate significantly from a circle or a plane and therefore a method that facilitates the...
Hydrostatic pressure, arching of the soil and electro-osmotic forces have each been suggested as the dominant factor to account for stability of trench excavations in cohesionless soils supported by clay slurries. The Authors suggest that the most important mechanism is the hydrostatic pressure...
A clay with near perfect particle parallelism was prepared by consolidating a slurried kaolin in a large oedometer. Shear box samples trimmed at various angles to the compression direction revealed no significant difference in drained strength. Samples with original bedding normal and parallel to...
In Section 1 I shall attempt to demonstrate how the need for a transformational rule, Tuni, uniting features under an NP node, rises in a transformational grammar containing a certain type of deletion transformation. Tuni will be investigated further (formally in Section 2, informally in Section...
Seeds and embryos contained within the silicified ovuliferous cone Araucaria mirabilis from the Cerro Cuadrado petrified forest are described. One wingless seed, 0.8-1.3 cm in length and 0.2-0.6 cm in width, is embedded in each ovuliferous scale. Seeds show a three-layered integument and a...
Studies of Paleozoic Seed Ferns: Anatomy and Morphology of Morphology of Microspermopteris aphyllum.Download
The discovery of numerous specimens of the monostelic pteridosperm genus Microspermop- teris in Pennsylvanian coal ball petrifactions from the Lewis Creek and What Cheer localities provides additional information about the anatomical and morphological variability within the genus. Specimens are...
