Spontaneous imbibition is of special importance to oil recovery from fractured reservoirs. Laboratory measurements of volume of liquid imbibed versus time are often used in the prediction of oil recovery. Imbibition measurements also provide a useful approach to the complex problem of characterizing the wetting properties of porous media. Correlation of a large body of data for imbibition of br...

Abstract Due to the high demand for natural aggregates in pavement construction, researchers have been looking alternative materials replace aggregate. In this research, optimum binder content of asphalt mixture incorporate limestones was investigated. The tested according Marshall method. About 20 % limestone used as aggregate replacement asphaltic concrete mixture. To determine stability, vol...

A method for the successful extraction of sequestered cellular DNA from 14,000-year-old fossil bones was developed and applied to asphalt-preserved specimens of the extinct saber-toothed cat, Smilodon fatalis. Two distinct gene segments, the mitochondrial gene for 12S rRNA and nuclear FLA-I (the feline class I major histocompatibility complex gene), from three different individual fossil specim...
