Groundwater samples were collected from eight wells in remote Antelope Creek valley, Idaho. Seven out of eight locations showed that groundwater 222 Rn concentrations were much greater than 11 Bq/L (300 pCi/L), a maximum contaminant level (MCL) proposed by United States Environmental Protection Agency (USEPA). Rock and soil samples collected near the sampling wells revealed that 238 U contents ...

The Beaverhead impact structure, in southwestern Montana (44°36-N;112°58'W), was identified recently by the presence of shatter cones and impactitcs in outcrops of Proterozoic sandstones of the Belt Supergroup [1]. The cones occur over an area > 100 km. Because the geologic and tectonic history of this region is long and complex, the outline of the original impact crater is no longer identifiab...

Background: Negative regulatory mechanisms of ROCK signaling are poorly understood. We have discovered a novel mechanism to attenuate ROCK signaling. Results: Coronin1B is a novel binding partner of ROCK2 that inhibits ROCK signaling to myosin. Conclusion: Coronin1B regulates ROCK by a novel signal attenuation mechanism. Significance: Coronin1B attenuation of ROCK signaling is associated with N...

Rock bolts have been widely used as rock reinforcing members in underground coal mine roadways and tunnels. Failures of rock bolts occur as a result of overloading, corrosion, seismic burst and bad grouting, leading to catastrophic economic and personnel losses. Monitoring the health condition of the rock bolts plays an important role in ensuring the safe operation of underground mines. This wo...

[1] Experimental data for alteration of synthetic Martian basalts at pH = 0–1 indicate that chemical fractionations at low pH are vastly different from those observed during terrestrial weathering. Rock surface analyses from Gusev crater are well described by the relationships apparent from low-pH experimental alteration data. A model for rock surface alteration is developed, which indicates th...

In terms of target detection and classification, scattering from exposed rock on the seafloor, (i.e., individual rocks and rock outcrops) presents some of the most difficult challenges for modern MCM and ASW sonar systems in shallow water. Work on characterizing, modeling and simulating mean levels and other statistical measures of acoustic scattering from rocks and rock outcrops is therefore c...

Since rock fracture is a key property for different rock engineering applications, rock fracture measurement is often carried out in classifying the rock mass. Most geo-mechanics models (e.g. finite element) are of the equivalent continuum type in which fractures are represented not individually, but by their influence on a large element of the rock mass. Elastic modulus, for example, is obtain...

Most empirical and numerical approaches to design in rock mechanics incorporate rock mass classification. Numerical design methods generally use classification values to calculate input parameters for stress-based failure criteria. Empirical methods use classification to allow comparisons between similar rock mass conditions, generally based on a graphical design technique that differentiates s...
