The prevailing paleocurrent direction was towards the northnorthwest. A significant difference, however, exists between the wave lengths of the ripples in the Kope and Fairview.

متن کاملFlume experiments on the migration rate of wave - formed ripple marks
The migration rate of wave-formed ripple marks was investigated using a twodimensional wave flume. Well sorted fine-grained sand (0.2 mm in diameter) was placed on a 1/20-fixed slope and an adjacent part of the horizontal flume bottom. The onshore migration rates of ripples and near-bottom orbital velocities were measured at three sites along the slope with different water depths and at one sit...
متن کاملTABLE OF MARKS OF FINITE GROUPS
Let G be a finite group and C(G) be the family of representative conjugacy classes of subgroups of G. The matrix whose H;K-entry is the number of fixed points of the set G=K under the action of H is called the table of marks of G where H;K run through all elements in C(G). In this paper, we compute the table of marks and the markaracter table of groups of order pqr where p, q, r are prime numbers.
