heterogeneity within the orientalist discourse: representation of the orient in womens travelogues and mens paintings
from 1950s onward, new theories and critical approaches burgeoned across humanities. these theories were context-oriented; as a result, the analysis of discursive practices gained significance. thus, social, political, historical and cultural discourses that have been hitherto marginalized and considered inferior to literary texts, were introduced as important texts to be analyzed by critics. o...
Global variation of body‐wave attenuation in the upper mantle from teleseismic P wave and S wave spectra
[1] We constrain the spatial variation of P‐wave (tP*) and S‐wave (tS*) attenuation by inverting 190,000 teleseismic P‐ and S‐wave spectra up to 0.8 Hz. These spectra are derived from 250 deep earthquakes recorded at 880 broadband global and regional network stations. The variance and ratios of tP* and tS* values are consistent with PREM’s upper mantle velocity and Q structures and conventional...
متن کاملP and S wave tomography of the mantle beneath the United States
Mantle seismic structure beneath the United States spanning from the active western plate margin to the passive eastern margin was imaged with teleseismic P and S wave traveltime tomography including USArray data up to May 2014. To mitigate artifacts from crustal structure 5–40 s, Rayleigh wave phase velocities were used to create a 3-D starting model. Major features of the final P and Smodels ...
متن کاملCrust and upper mantle P- and S-wave delay times at Eurasian seismic stations
Median crust and upper mantle Pand S-wave delay times, based on residuals for teleseismic Pand S-wave arrival times included in the groomed ISC/NEIC database of Engdahl et al. [Bull. Seism. Soc. Am. 88 (1998) 722] are estimated as functions of time and azimuth for Eurasian seismic stations. The effects of source and lower mantle 3-D structure on the station residuals are corrected by ray tracin...
متن کاملMantle seismic structure beneath the MELT region of the east pacific rise from P and S wave tomography
Relative travel time delays of teleseismic P and S waves, recorded during the Mantle Electromagnetic and Tomography (MELT) Experiment, have been inverted tomographically for upper-mantle structure beneath the southern East Pacific Rise. A broad zone of low seismic velocities extends beneath the rise to depths of about 200 kilometers and is centered to the west of the spreading center. The magni...
