A paraboloidal bow shock model is developed in order to estimate the surface distribution of gas shock-induced modifications surrounding Venusian impact craters. We apply two-dimensional oblique shock dynamics to describe a three-dimensional paraboloidal-shaped bow shock impinging upon an assumed incompressible Venusian surface. The effects of the hypersonic atmospheric shock acting on the Venu...

derik geothermal region has area of 242 km2 and is located 10 km to the west of salmas city in west azarbaijan province of iran. the most outstanding surface manifestations of geothermal energy in this region are three warm springs and outcrops of travertine deposits and quaternary basalt outcrops around warm springs. temperature range of warm springs varies from 31 to 32.6 °c. we visited and s...

the main limitation of radar interferometry in measuring ground displacements is due to phase propagation delays caused by the troposphere. tropospheric water vapor is a major limitation for high precision interferometric synthetic aperture radar (insar)applications. using global meteorological reanalysis models and merisdata are two methods that can be used for correcting the effects of the tr...

Data collected during the 2004 Long-range Ocean Acoustic Propagation Experiment provide absolute intensities and travel times of acoustic pulses at ranges varying from 50 to 3200 km. In this paper a subset of these data is analyzed, focusing on the effects of seafloor reflections at the shortest transmission range of approximately 50 km. At this range bottom-reflected (BR) and surface-reflected...

The local earthquake events recorded north of Panjal thrust (=Main Central thrust) and Main Boundary Thrust (MBT) by the four broadband seismological observatories located at Jammu, Poonch, Doru and Bani in Jammu and Kashmir from January to May, 2012 have coda magnitudes ranging from 1.7 to 3.8 were used to compute source parameters namely; seismic moment, source radius, and stress drop. These ...

The intermediate-depth (50–180 km) seismicity beneath Myanmar provides direct evidence of the subducting Indian slab. However, historic lack regional seismic observations leads to previous low-resolution models that show large variations in slab geometry Myanmar. depth extent and morphology are still poorly known. In this study, we conduct a joint inversion teleseismic P-wave traveltimes from r...

Protein phosphatase 4 (PPP4) is a protein serine/threonine phosphatase that has been implicated in microtubule organization at centrosomes. Complexes of PPP4 with high apparent molecular masses (450 and 600 kDa) were purified from mammalian skeletal muscle and testis to near homogeneity. Amino acid sequences derived from a protein component present in both complexes were utilized to identify a ...

Abstract. Remnants of the Caribbean Large Igneous Plateau (C-LIP) are found as thicker than normal oceanic crust in Sea that formed during rapid pulses magmatic activity at ?91–88 and ?76 Ma. Strong geochemical evidence supports hypothesis C-LIP due to melting plume head Galápagos hotspot, which interacted with Farallon (Proto-Caribbean) plate eastern Pacific. Considering tectonics theory, it i...

In the southern Tibetan plateau, which is considered to be the ongoing India–Eurasia continental collision zone, tracing of the Indian crustal front beneath Tibet is still controversial. We conducted deep subsurface electrical modeling in southern Tibet and discuss the geometry of the front of the Indian crust. Three areas along the Yarlung-Zangbo river zone for which previous magnetotelluric (...
