Measuring extensive air showers with Cherenkov light detectors of the Yakutsk array: The energy spectrum of cosmic rays

The energy spectrum of cosmic rays in the range E ∼ 1015 eV to 6 × 1019 eV has been studied using the air Cherenkov light detectors of the Yakutsk array. The total flux of photons produced by relativistic electrons (including positrons as well, hereafter) of extensive air showers in the atmosphere is used as the energy estimator of the primary particle initiating a shower. The resultant differe...

Clusters in the Arrival Directions of 2 × 1017-eV Cosmic Rays Detected at the Yakutsk EAS Array

1. Primary cosmic radiation (PCR) of ultrahigh energies (E0 > 4 × 1017 eV) is thought to consist primarily of charged particles, protons, and nuclei of various chemical elements. These charged particles are strongly mixed by the magnetic field of the galaxy and distributed almost isotropically over the celestial sphere. For this reason, it is difficult to find the local sources of PCR. The abov...

gradual erasure of subjectivity: a study of samuel beckett’s trilogy in the light of postmodernism

ساموئل بکت بیشتر از هر نویسنده دیگری در نیم? دوم قرن بیستم با گفتارش زمان? ما را به آستان? از هم پاشیدگی کشانده است، آستانه ای که در آن مدرنیته با سرانجام گریزان اما غیرقابل اجتناب خود مواجه می شود. در این تحقیق روی مفهوم فردیت و محو آن در دوران پسامدرن تاکید شده و در طی آن سعی شده است که فردیت مدرن و پسامدرن در رمان های سه گانه بکت بررسی گردد. تحقیق حاضر یک بررسی کتابخانه ای و کیفی بر روی سه ر...
