J. B. Cheatham Jr.composed of the alga . Kutzig. The unusual properties of this alga to secrete hydrocarbon oils has made it a prime contributor to the oil-rich oil shales such as torbanites, Green River and in localised various other organic-rich deposits. The alga is associated with flooding of Permian swamps and o

Prediction of Elastic-Plastic Wave Profiles in Aluminum 1060-0 Under Uniaxial Strain Loading,e of two flat plates has a two-wave structure as shown in Fig. 1. The elastic wave propagates at velocity . with intensity . where . is the yield stress of the material in a uniaxial stress test, λ and μ are Lame’s constants, and p is the material density. This is followed by the higher intensity plastic wave travelling at a slower velocity
