Measurements of low-frequency sound propagation over the areas of the Australian continental shelf, where the bottom sediments consist primarily of calcarenite, have revealed that acoustic transmission losses are generally much higher than those observed over other continental shelves and remain relatively low only in a few narrow frequency bands. This paper considers this phenomenon and provid...

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...

climate change is one of the major global concerns. emission of anthropogenic greenhouse gases is the main cause of climate change. one way of reducing the emissions is the application of carbon capture and storage (ccs) in geological formations. in this study, feasibility of ccs was studied in an iranian gas production area located in the northern persian gulf coast in the south of country. th...

coastal fars gravimetry project in fars province was carried out to find the buried salt domes and to determine characteristics of faults in this area. the lavarestan structure was covered by 4203 gravimetry stations in a regular grid of 1000*250 m. depth structural model of this anticline made in previous studies was based on geological evidences and structural geology measurements. in order t...

Abstract A hydrogeochemical study was carried out on the shallow Catania Plain alluvial aquifer, in eastern Sicily to reconstruct its hydrogeological structure, meteoric recharge and assess influence of human activities groundwater. To characterize geochemistry two sampling campaigns were out, August–October 2004 April–May 2005 47 sites distributed throughout plain. The samples collected analyz...

Abstract The construction industry in Abu Dhabi is thriving and its coastline has some of the most ambitious structures world. Whilst subsurface evaporitic calcareous soft rocks this region are great geological interest, they relatively poorly understood from a geotechnical engineering perspective, forcing foundation designs to be overly conservative. Understanding stiffness underlying geology ...

Carbonatite intrusive complexes are important hosts for Rare Earth Elements (REE) deposits and commonly affected by surficial weathering processes. Mount Weld REE deposit of Western Australia is one the world’s richest here we present whole-rock mineral geochemical data on compositions primary weathered carbonatites. The concentrations in magmatic carbonatites at vary two orders magnitude, sugg...

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...
