Introduction: Previous work on smaller complex craters less than 20 km in diameter [1-4] has uncovered a petrogenetic (deformation/modification) sequence expressed by cross-cutting relationships between deformation fabrics in target rocks. This sequence is most apparent in the uplifted rocks of crater floors (i.e. central peaks/uplifts). The deformation fabrics that have been studied include ma...

Pores and microfractures provide storage spaces migration pathways for gas accumulation in tight sandstones with low porosity permeability, acting as one of the controlling factors production. The development a rational rock physics model is essential better understanding elastic responses sandstone complex pore structures. Accordingly, seismic characterization pores based on provides valuable ...

Osseointegration refers to the connection between living bone and surface of an implanted device that bears functional load. The Piezosurgery device, as compared rotating instruments, promotes improved wound healing reduces occurrence microfractures smear layer. In this case report, objective was investigate impact using a piezoelectric for preparing osteotomy site on loss crestal around dental...

Introduction: Evidence on the management of chondral defects patella arises from studies in which patellofemoral joint was treated together with femorotibial and primary revision settings. Furthermore, superiority Autologous Matrix Induced Chondrogenesis (AMIC) over microfractures (MFx) for patellar is uncertain. Therefore, present study compared isolated AMIC versus MFx focal unipolar facet jo...

Brittleness is important in the evaluation of fracturing ability shale reservoir and has a significant impact on gas exploration development. This paper discusses characteristics controlling factors brittleness continental Da’anzhai Member Ziliujing Formation Lower Jurassic age northeast Sichuan Basin. Continental lithofacies their associations were grouped into four main rock types: clayey sha...

An hourly scale precursor of inland earthquakes (EQs) is revealed in this paper. Several EQ cases China have been reported. As indicated by a table listing 23 EQs and their shock time, epicenter location, magnitude, near-epicenter weather conditions, start time duration, when the conditions are fair near epicenter, an anomalously negative atmospheric electrostatic signal readily observable appr...

Physical and geochemical characteristics of shale play conclusive role in confirming operation measures during drilling and stimulation. The properties of shale samples from Jiyang depression were investigated through X-ray diffraction, scanning electron microscope, adsorption isothermal, high pressure mercury intrusion, methylene blue trihydrate, pressure pulse decay, tests of specific water w...

The application of 20 kHz high-intensity ultrasound during extraction of oil from two varieties of soybeans (TN 96-58 and N 98-4573) using hexane, isopropanol and a 3:2 hexane–isopropanol mixture was evaluated. In a simplified extraction procedure, ground soybeans were added to solvents and ultrasonicated between 0 and 3 h at ultrasonic intensity levels ranging from 16.4 to 47.6 W/cm. Oil was r...

Fractures and faults riddle the Earth's crust on all scales, and the deformation associated with them is presumed to have had significant effects on its petrological and structural evolution. However, despite the abundance of directly observable earthquake activity, unequivocal evidence for seismic slip rates along ancient faults is rare and usually related to frictional melting and the formati...
