Translation is a challenging task, especially when it deals with ideological turns. Translations may be ma- nipulated and rewritten by rival parties to serve their own interests and convey their own ideologies and also translators play a significant role in negotiating meaning within social and political processes. In the field of ideological turns, different matters are being discussed f...
a survey on the abundance and diversity of fish larvae along the iranian waters of the oman sea, extending from hormuz strait to gowatr bay, was carried out in 2009 (before and post monsoon). fish larva were collected by a bongo net (300 µ mesh size) and temperature, salinity, dissolved oxygen, ph, chlorophyll-a, clarity, nitrate, nitrite, silicate and sulfate by oceanic data recorder (ctd) and...

BACKGROUND In the current era of strong worldwide market couplings the global financial village became highly prone to systemic collapses, events that can rapidly sweep throughout the entire village. METHODOLOGY/PRINCIPAL FINDINGS We present a new methodology to assess and quantify inter-market relations. The approach is based on the correlations between the market index, the index volatility...
We outline the development and the application in a field test of the Autonomous Fibre-Optic Rotational Seismograph (AFORS), which utilizes the Sagnac effect for a direct measurement of the seismic-origin rotations of the ground. The main advantage of AFORS is its complete insensitivity to linear motions, as well as a direct measurement of rotational components emitted during seismic events. Th...
The ground motion attenuation relations have been proposed on an empirical basis and widely been used for ground motion prediction in convenient and efficient way. The accuracy of the predictions, however, is not so high given an earthquake magnitude and distance, the uncertainty of the relations has, say, 0.5 or more in a natural logarithmic standard deviation, which significantly governs the ...
We determined the centroid moment tensor (CMT) solutions of earthquakes that occurred along the North Anatolian fault (NAF) beneath the Sea of Marmara and the Aegean Sea, using data obtained from Turkey’s broadband seismograph network. The CMT solution of the 2014 Aegean Sea earthquake (Mw 6.9) represents a strike-slip fault, consistent with the geometry of the NAF, and the source-time function...
[1] Satellite imagery reveals that a series of large icebergs (B15B in April 2001, C19 in June 2003, and B15A in October 2005) broke up or fractured while exiting the Ross Sea in a narrowly defined area off Cape Adare, Antarctica. Examination of recent swath‐mapped bathymetric observations revealed that the principle agent of these breakups is a previously unknown 9 km long ridge with minimum d...
[1] Clear atmospheric pressure changes associated with the 2003 Tokachi-Oki, Japan, earthquake with Mw 8.3 were recorded with the microbarographs distributed in Japan. The pressure change starts at the arrival of seismic waves and reaches its maximum amplitude at the arrival of Rayleigh waves, suggesting that the observed pressure change was driven by the ground motion of seismic waves passing ...
Between 1957 and 1982, water flooding was conducted to improve petroleum production in the Cogdell oil field north of Snyder, TX, and a contemporary analysis concluded this induced earthquakes that occurred between 1975 and 1982. The National Earthquake Information Center detected no further activity between 1983 and 2005, but between 2006 and 2011 reported 18 earthquakes having magnitudes 3 an...
