Abstract After reviewing many literature foundations, the thesis combines basic methods of elastic mechanics with mathematical knowledge, sets bipotential stress potential complex function and analyses relationship between component, strain component function, applies variable function. The expression relevant is derived, displacement boundary conditions surrounding rock shallow circular tunnel...

In recent years, ocean current turbines have proven to be a reliable device for renewable energy generation. A crucial element of these are the foundations, since they limit displacement turbine, which is key in achieving efficiency conversion, and can account up 26% total cost project. Most design procedures foundations focus on sandy clayey soils, but rock soils often predominate tropical loc...

We recently identified a novel human protein kinase, p160 ROCK, as a putative downstream target of the small GTPase Rho. Using the human ROCK cDNA as a probe, we isolated cDNA of two distinct, highly related sequences from mouse libraries. One encoded a mouse counterpart of human ROCK (ROCK-I), and the other encoded a novel ROCK-related kinase (ROCK-II). Like ROCK/ROCK-I, ROCK-II also bound to ...

Drilling into a rock massif is energetically extremely consumptive process. Hence the optimization of drilling regime with objective of energy consumption minimization, is very important. Proposed article discusses partial problem of this problem. During the drilling process it is useful to know the drilled rock type, whereas to particular drilled rock needs convenient drilling regime, which is...

protein serine/threonine kinase (ROCK), is one of the central regulatory molecules for cytoskeleton control and cell adhesion process. ROCK also involves in other cell functions such as apoptosis and tumor invasiveness. Rho kinase is thought to play an important role in a variety of cellar functions such as stress fiber formation, focal adhesion formation, cell aggregation, cell morphology, cyt...

In this work, the effect of rock bolt angle on the shear behavior of Rock Bridges is investigated using the particle flow code in two dimensions (PFC2D) for three different Rock Bridge lengths. Firstly, the calibration of PF2D is performed to reproduce the gypsum sample. Then the numerical models with the dimensions of 100 mm * 100 mm are prepared. The Rock Bridge is created in the middle of th...

The rock composition of karst area is mainly limestone, which easy to be eroded and dissolved by water, forming a complex fragile tectonics. Under the action earthquake, instability stratum aggravated. mid story isolation structure new type developed from basic structure, irregular buildings are highly susceptible adverse seismic conditions. Previous studies have mostly adopted assumption rigid...

No prior research has documented the different types of rock coatings in Yosemite Valley, despite the evident black streaks down Yosemite Falls, the light granitic rock exposed by recent rock falls contrasting with dark rock coatings, and the millions of visitors who have photographed the coated rocks of Yosemite. This paper identifies the types of rock coatings found on Half Dome, in Yosemite ...

Rock tensile strength (TS) is an essential parameter for designing structures in rock-based projects such as tunnels, dams, and foundations. During the preliminary phase of geotechnical projects, rock TS can be determined through laboratory works, i.e., Brazilian (BTS) test. However, this approach often restricted by laborious costly procedures. Hence, study attempts to estimate BTS values empl...
