متن کاملCarnivoran Remains from the Malapa Hominin Site, South Africa
Recent discoveries at the new hominin-bearing deposits of Malapa, South Africa, have yielded a rich faunal assemblage associated with the newly described hominin taxon Australopithecus sediba. Dating of this deposit using U-Pb and palaeomagnetic methods has provided an age of 1.977 Ma, being one of the most accurately dated, time constrained deposits in the Plio-Pleistocene of southern Africa. ...

15 صفحه اولLow Reynolds number flows across ordered arrays of micro-cylinders embedded in a rectangular micro/minichannel
Pressure drop of ordered arrays of cylinders embedded inside microchannels is experimentally and analytically studied. Two independent modeling techniques are used to predict the flow resistance for the creeping flow regime. The pressure drop is expressed as a function of the involved geometrical parameters such as micro-cylinder diameter, spacing between adjacent cylinders, channel height, and...
