We present and discuss the spatial distribution of more than 1000 aftershocks of the largest continental intraplate earthquake to occur during the modern seismological period. The data were recorded on a network of eight portable digital seismographs deployed for 3 weeks starting 17 days after the mainshock. We have calculated high-quality single-event locations, based on a 1D velocity model de...

version lines of ammonia (NH 3) have been detected toward the nuclear 40 00 sized bar of the nearby spiral galaxy Maaei 2. The relative intensities of the ammonia lines are characterized by a rotational temperature of 85 K. This is higher than rotational temperatures measured toward IC 342 and most Galactic Center clouds, implying kinetic temperatures > 100 K. Since the kinetic temperature of t...

A downhole seismometer at 900-m depth and a temporary network of surface stations were deployed to use rays from local microearthquakes to study the upper and middle crust beneath the Long Valley caldera. The downhole seismograms show S waves with high apparent amplitudes from earthquakes located 2-20 km to the south of the downhole seismometer. In contrast, S waves from earthquakes located in ...

[1] We present tomographic images of the mantle structure beneath the western United States. Our Dynamic North America Models of P and S velocity structure (DNA07‐P and DNA07‐S) use teleseismic body waves recorded at ∼600 seismic stations provided by the Earthscope Transportable Array and regional networks. DNA07‐P and ‐S benefit from the unprecedented aperture of the network while maintaining ...

Aim Rosa damascene Mill. belongs to the family of Roseaceae and its essential oil is produced in large amounts in Iran. The wide application of rose oil has raised questions about potential adverse health effects. We have investigated cytotoxic activity and genotoxic effects of Rosa oil from Kashan, Iran. Methods The cytotoxic effect and IC50 of the essential oil on the cell lines was studied f...

Prior studies suggest that certain issues, principles and policies are related to the successful institutionalisation of Knowledge Management (KM). This article examines the role these three factors play in the establishment of KM and report on an empirical study conducted in 86 South African based

[1] Geologic investigations of how the Tibetan plateau is currently deforming have focused primarily on its boundary faults. Consequently, how the interior of the plateau deforms remains poorly understood. To fill this gap in knowledge, we conducted field mapping, analysis of remote sensing and digital topographic data, and reinterpretation of existing geologic maps in central Tibet. This study...

abstract shah jahan, based on structural zone is located in south of kapedagh and in eastern side of aladagh mountains in 37◦ till 37◦25' northern latitude and 57◦30' till 58◦30' eastern longitude of northeastern part of iran. geomorphologic and tectonic elements show that this area is partly young and mountains can be affected highly by geomorphologic and hydrologic elem...

Nutrient and chlorophyll a concentrations and distributions in two adjoining regions of the South Atlantic Bight (SAB), Onslow Bay and nearshore Long Bay, were investigated over a 3-year period. Onslow Bay represents the northernmost region of the SAB, and receives very limited riverine influx. In contrast, Long Bay, just to the south, receives discharge from the Cape Fear River, draining the l...
