Heterotrophic bacterial growth and the chemical composition of dissolved organic matter (DOM) produced by bacteria from freshwater and marine environments were monitored during experiments with artificial media containing glucose as the sole carbon source. Glucose was quickly consumed, and DOM was released during bacterial growth. Percentages of extracellular release of DOM from bacteria ranged...

One of the ways to define mobility in a transportation system is total travel time for all travelers using the transportation network. A good assessment of the mobility is essential for knowing the points of congestion in the network and the factors responsible for the congestion. Also the change in mobility from the baseline to the horizon year would give the modeler an idea of the effectivene...

The synthesis of polycyclic aromatic hydrocarbons (PAHs) from benzene by shock waves was studied, in order to search for a novel possibility of PAH formation under cosmochemical conditions. Shock waves generated by projectile impacts were transmitted into pure benzene, and then the shocked samples were analyzed by FID gas chromatography and gas chromatography mass spectrometry. The projectile v...

Despite the paucity of direct evidence about the origin of human language, the great intrinsic interest in this question has made it difficult for writers to resist speculating about it (Harnad et al., eds., 1976; Merlin, 1991; Deacon, 1997; Jablonski & Aiello, eds., 1998; King, ed., 1999; Knight et al., eds., 2000). The following attempts to bring a fresh perspective on this old question, usin...
