the search for the self in becketts theatre: waiting for godot and endgame
this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
15 صفحه اولA search for 4750- and 4765-MHz OH masers in Southern Star Forming Regions
We have used the Australia Telescope Compact Array (ATCA) to make a sensitive (5-σ ≃ 100 mJy) search for maser emission from the 4765-MHz 2Π1/2 F=1→0 transition of OH. Fifty five star formation regions were searched and maser emission with a peak flux density in excess of 100 mJy was detected toward fourteen sites, with ten of these being new discoveries. In addition we observed the 4750-MHz 2Π...
متن کاملSearch for radiative pumping lines of OH masers : I . The 34 . 6 μ m absorption line towards 1612 MHz OH maser sources . ⋆
The 1612 MHz hydroxyl maser in circumstellar envelopes has long been thought to be pumped by 34.6 µm photons. Only recently, the Infrared Space Observatory has made possible spectroscopic observations which enable the direct confirmation of this pumping mechanism in a few cases. To look for the presence of this pumping line, we have searched the Infrared Space Observatory Data Archive and found...
متن کاملThermal OH (1667/65 MHz) Absorption and Nonthermal OH (1720 MHz) Emission Towards the W28 Supernova Remnant
Received ; accepted – 2 – ABSTRACT The W28 supernova remnant is an excellent prototype for observing shocked gas resulting from the interaction of supernova remnants (SNRs) and adjacent molecular clouds (MCs). We present two new signatures of shocked molecular gas in this remnant. One is the detection of main-line extended OH (1667 MHz) absorption with broad linewidths. The column density of OH...
متن کاملGbt Observations of Ic443: the Nature of Oh(1720 Mhz) Masers and Oh Absorption
We present spectral line observations of the ground state transitions of hydroxyl(OH) toward supernova remnant(SNR) IC443 carried out with the Green Bank Telescope. Weak, extended OH(1720 MHz) maser emission with OH(1667,1665,1612 MHz) absorption is detected along the southern extent of the remnant where no bright compact maser sources have been previously observed. These newly detected SNR-typ...
