Locating Groundwater at Ta-Kang-Shan and Ping-Ting Sites by Geoelectric Methods

Locating Slippery Highway Sites by Accident Analysis

IN T R O D U C T IO N It is generally agreed that a wet pavement surface presents less resistance to skidding than does the same surface in a dry condition. It is also well known that ice and snow are very slippery; but on the other hand, they are special conditions which do not reflect any skid characteristic of the pavement surface. It is, therefore, the wet surface condition that is critical...

Derivation of rate equations for multisite ping-pong mechanisms with ping-pong reactions at one or more sites.

It has become clear as the result of the pioneering studies of Northrop on transcarboxylase (l), and the later studies in Lardy’s (2) and Utter’s (3) laboratories on pyruvate carboxylase that biotin-containing enzymes have two-site ping-pong mechanisms in which biotin is carboxylated at one site, and in turn carboxylates a substrate at the second site. The rate equations for such mechanisms hav...

Investigation of Geoelectric-While-Tunneling Methods through Numerical Modeling

In this paper, we explore the fundamental physics behind the application of electrical resistivity and induced polarization during tunnel boring machine (TBM) mining. Using finite element (FE) analysis, we model the electric field created when current is injected into the surrounding ground via electrodes in the TBM cutterhead. The FE analysis simulates a variety of materials and conditions inc...
