Historical Archaeologists (SHA) in Sacramento, California….a good time was had by all (or most, anyway). While at the conference I attended this year’s forum sponsored by the African Diaspora Archaeology Network…By the way, I REALLY like these […]

First lady Laura Bush was the campus of Howard University in late October, along with many others, to conduct a session of the White House Conference on Helping America’s Youth. Apparently neither she, nor the Howard University officials, expected a large protest to ensue…. “What started as a demonstration of 50 students standing around the […]

Due to an unpleasant chain of events, the African-American Archaeology Listserv was deleted from Yahoo groups a few weekends ago. John McCarthy & I have reestablished the list, but unfortunately we cannot reestablish our membership (almostguiding structure, which is analogous to the second one, is structured to enclose only half the portion of the rolling member as that disclosed by U.S. Pat. No. 6203199, in which the upper and the lower walls are used to control the motion of the rolling member. The structure is also created by using the plastic molding process, which being similar to aforesaid two types, can not be free from the problems of shrinking deformation and an ineligible frictional resistance caused by a large contact area as that described in the former two types of structure. The dimensional deviation caused by shrinking deformation may lead to retardation of the rolling member by the circulation guiding structure and, in the worst case scenario, the function of the linear transmission
