Abstract Coastal aquifers are essential for coastal communities worldwide, one of which is in the Mandalika area (Lombok Island, Indonesia). This tourism sector requires an adequate supply fresh water. a dominated by alluvial plains, excellent rock as aquifer. However, plains also susceptible to seawater intrusion. study uses combination gravity and geomagnetic methods estimate bedrock potentia...

The overarching goal of the study is to develop a rockfall susceptibility map for Valchiavenna (SO), located in Italian Central Alps. approach was two-fold: first part work consisted developing geomechanical maps, which are relevant rock mass instability, whilst second aimed implementation obtained maps as predictors statistically based model. chosen target variables, collected an available fie...

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...

The Three Gorges are the areas in which the geological disasters are very serious. There often happen great landslide disasters, which brings tremendous threat to normal running of the Three Gorge Dam and the properties and lives of the residents in the reservoir. So landslide susceptibility analysis is an important task of prevention and cure of landslides in the Three Gorges. In this paper, l...

[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...
