this study tried to explore disciplinary variations of web blurbs across soft and hard knowledge fields on the one hand, and to illustrate how academic publishers exploit interactional metadiscourse devices in move structure of their blurbs on the other.
The geomagnetic field variations measured at the surface of the Earth are composed of both internal and external parts. The external field arises from the sources in the magnetosphere and ionosphere, whereas the internal field is generated by the currents induced within the Earth. The internal part may in some situations comprise a notable part of the measured total field and thus a blind usage...
Solar activity is the dynamic energy source behind all solar phenomena driving space weather. During an active solar period, violent eruptions occur more often on the Sun. The solar flares (SFs) and coronal mass ejections (CMEs) shoot energetic and highly charged particles towards Earth that ensuing ionospheric and geomagnetic disturbances. The some geomagnetic disturbances illuminate night ski...

today, the route for economic development in most countries is the same as international open competitive economy. economic institutes well known that supportive public economy belonged on the past and they may compete in the global economy. it is obvious that if they have no competitive potency or not familiar with competition technique, they may be devastated. banking system aims to collect t...
Using PSD (Power Spectral Density) data on electron density and electric field variations observed on board Aureol-3 satellite at low-to-mid-latitude ionosphere we analyze a scale distribution of the ionospheric turbulence in a form k , where k is the wave number and α is the spectral index. At first, high-resolution data in the near-equator region for several orbits have been processed. In thi...
Ultra low frequency (ULF) wave activity in the high-latitude ionosphere has been observed by a high frequency (HF) Doppler sounder located at Tromsù, Norway (69.7°N, 19.2°E geographic coordinates). A statistical study of the occurrence of these waves has been undertaken from data collected between 1979 and 1984. The diurnal, seasonal, solar cycle and geomagnetic activity variations in occurrenc...
the present study reports an analysis of response articles in four different disciplines in the social sciences, i.e., linguistics, english for specific purposes (esp), accounting, and psychology. the study has three phases: micro analysis, macro analysis, and e-mail interview. the results of the micro analysis indicate that a three-level linguistic pattern is used by the writers in order to cr...
abstract the present thesis seeks to critically read george orwell’s nineteen eighty-four and animal farm in the light of louis althusser’s thought and theory. the present thesis proceeds to examine and demonstrate althusser’s major concepts including ideological state apparatuses (isas), repressive state apparatuses (rsas), the structure, the subject, and ideological interpellation which r...
